The wiring device case 1 includes a body 3 and a cover main body 2. The cover main body 2 constitutes at least a part of a wiring device cover 20 (hereinafter also simply referred to as "cover 20"). In other words, the wiring device device 10 according to the present embodiment includes the wiring device 4 and the cover 20 including the cover body 2.

In this embodiment, the wiring device 4 has the function of an outlet to which a plug of an electrical device is connected and supplies power to the electrical device. Here, as an example of an electrical outlet, a two-port electrical outlet for AC 100V with a grounding electrode and to which two plugs can be connected at the same time is exemplified. Further, in this embodiment, as the wiring device device 10, an outdoor wiring device device 10 that is attached to the outer wall of a building is illustrated. The building in which the wiring device device 10 is installed is, for example, a single-family house, an apartment complex, an office, a store, or a nursing care facility. That is, in this embodiment, the wiring device device 10 is an outdoor outlet device.

The wiring device device 10 is attached to a construction surface (outer wall surface of a building) with electric wires electrically connected to the wiring device 4. In this wiring device device 10, by connecting the plug of the electrical device to the wiring device 4, power can be supplied from the wiring device 4 to the electrical device. Here, the wiring device device 10 includes a connection surface 411 in which an insertion hole 412 (see FIG. 1) and a ground insertion hole 413 (see FIG. 1) are formed for connecting the plug 8 (see FIG. 3) in the wiring device 4. It can be attached to the construction surface with the side facing downward. Therefore, the plug 8 is connected to the wiring device 4 from below, making it difficult for rainwater to enter the inside of the wiring device 4 through the insertion hole 412 and the ground insertion hole 413.

The wiring device device 10 configured in this manner is used to supply power to various electrical devices such as lighting fixtures, electronic signboards, vending machines, electric vehicles, water heaters, and power tools. That is, by connecting the plug 8 of the cable 80 (see FIG. 3) connected to the electrical device to the wiring device device 10, power can be supplied from the wiring device 4 to the electrical device via the cable 80.

Here, the wiring device device 10 according to the present embodiment can cover the wiring device 4 with the cover 20 when the wiring device 4 is not in use. That is, the cover body 2 is configured to be movable (rotatable) between a closed position (see FIG. 2) that covers the wiring device 4 and an open position (see FIG. 1) that exposes the wiring device 4. In this wiring device device 10, when the wiring device 4 is not in use, the cover body 2 that is in the closed position covers the wiring device 4, and the cover body 2 is opened (set to the open position) to plug the wiring device 4. It is possible to operate the wiring device 4 such as connecting and disconnecting the wiring device 8. Further, the cover main body 2 is formed with a pull-out portion 231 for pulling out the cable 80.

The wiring device case 1 further includes a shaft 7 for connecting the body 3 and the cover main body 2. The body 3 holds a wiring device 4. The cover main body 2 is supported by the body 3 so as to be movable between a position that covers the wiring device 4 (closed position) and a position that exposes the wiring device 4 (open position). That is, when the cover body 2 is in the open position, the wiring device 4 is not covered by the cover body 2, and the wiring device 4 can be accessed from outside the wiring device case 1. Hereinafter, the cover 20 will be described using the direction in which the cover body 2 is in the closed position, unless otherwise specified.

The body 3 includes a vertically long rectangular frame 35, a storage portion 36 that protrudes forward from the front surface of the frame 35, and a rectangular plate-shaped extension 37 that protrudes downward from the lower edge of the frame 35. It consists of and. The body 3 is made of, for example, ASA (Acrylate Styrene Acrylonitrile) resin.

A ground terminal hole 351 is formed in the frame 35 at a position below the storage portion 36 and corresponding to the lower end of the extension terminal plate 45 . By tightening the terminal screw 47 to the extension terminal plate 45 from the front surface of the frame 35 through the ground terminal hole 351, the extension terminal plate 45 and the terminal screw 47 constitute a ground terminal. In other words, the grounding wire of the electrical equipment can be electrically connected to the extension terminal board 45. A rib 352 is formed on the outer periphery of the rear surface of the frame 35 over substantially the entire circumference. Furthermore, a pair of mounting holes 353 for passing mounting screws are formed in the frame 35.

The front surface of the storage section 36 is not parallel to the front surface of the frame body 35, but is inclined obliquely upward. As a result, the amount of protrusion of the storage section 36 from the front surface of the frame body 35 increases as it approaches the lower end edge of the storage section 36 in the vertical direction. In this embodiment, at least a portion of the front surface of the storage section 36 is not a flat surface but a curved surface that is convex diagonally upward. The inside of the storage section 36 is hollow. A first opening 361 is formed on the lower surface of the storage section 36, and a second opening 362 is formed on the rear surface of the storage section 36.

The wiring device 4 is stored in the internal space of the storage section 36. A pair of mounting pieces 431 through which the fixing screws 48 are inserted protrude from both left and right side surfaces of the second body 43 of the wiring device 4 . The wiring fixture 4 is fixed to the body 3 by a fixing screw 48. With the wiring device 4 fixed to the body 3, the lower surface (connection surface 411) of the wiring device 4 is exposed from the first opening 361 of the storage portion 36. In other words, the body 3 holds the wiring device 4 with the connection surface 411 of the wiring device 4 exposed through the opening (first opening 361) formed in the front surface of the body 3.

In the present embodiment, the body 3 is tilted in the vertical direction so that the connection surface 411 exposed from the first opening 361 faces slightly forward rather than vertically downward (directly below). Hold. Here, the wiring device 4 is attached to the body 3 with the entire housing 40 tilted so that not only the connection surface 411 but also the rear surface of the first body 42 and the front surface of the second body 43 are tilted with respect to the vertical direction. Retained. As a result, the insertion direction of the plug blade 81 (or pin 82) of the plug 8 (see FIG. 3) connected to the wiring device 4 is a direction slightly inclined with respect to the vertical direction. In other words, the plug 8 is connected to the connection surface 411 not from vertically below (directly below) but from diagonally in front.

A lock receiving portion 38 is formed on the front surface of the extension portion 37 . The lock receiving portion 38 constitutes the lock mechanism 5 together with the lock plate 52 held by the cover body 2. The lock receiving portion 38 has a lock hole 381 opening on the bottom surface. A leaf spring 382 is attached within the lock hole 381 with a screw 383.

A pair of guide protrusions 39 are further formed on the front surface of the extension portion 37 . The pair of guide protrusions 39 are located at the lower end of the front surface of the extension portion 37 and protrude from both ends in the left and right direction. The distance between the pair of guide protrusions 39 becomes smaller as the tip edges of the pair of guide protrusions 39 are approached. The pair of guide protrusions 39 have a function of guiding the movement of the cover body 2 by coming into contact with the inner surface of the cover body 2 when the cover body 2 moves from the open position to the closed position. A through hole 391 passing through the guide projection 39 in the thickness direction (horizontal direction) is formed in one (right side in this case) of the pair of guide projections 39 .

In addition to the above-described configuration, the body 3 further includes a water passage groove 31, a support portion 32, and a protruding piece 33 (see FIG. 1).

The water passage groove 31 is a groove located at the upper end of the body 3 and has an opening on the top surface. The water passage groove 31 is, for example, a groove for guiding rainwater or the like that has entered the space between the body 3 and the cover body 2 from the gap between the body 3 and the cover body 2 to both sides of the body 3 in the left and right direction. be. In other words, when water such as rainwater enters through the gap between the body 3 and the cover main body 2, this water is guided to both sides of the body 3 through the water passage 31, so that the wiring fixtures 4 exposed from the front of the body 3 are Less likely to get wet.

The support part 32 is a structure for rotatably supporting the cover main body 2 with respect to the body 3 by holding the shaft body 7. Here, the support part 32 is located at the upper end of the body 3 and supports the cover body 2 so that the cover body 2 can rotate around the rotation axis 300 (see FIG. 1). The axial direction of the rotating shaft 300 coincides with the left-right direction. Therefore, the rotation shaft 300, which is the center of rotation of the cover body 2, is located at the upper end of the body 3. The support portion 32 will be described in detail in the section “(2.5) Details of hinge structure”.

The protruding piece 33 is a structure for temporarily fixing the cover body 2 in the open position. In this embodiment, a pair of protruding pieces 33 are provided, and the pair of protruding pieces 33 protrude from both end surfaces of the support portion 32 in the left-right direction (see FIG. 9A). Details of the protruding piece 33 will be described in the section "(2.5) Details of hinge structure".

The cover 20 includes a cover body 2 that covers the wiring device 4, as shown in FIGS. 1 to 5. Since the wiring device 4 is stored in the storage section 36 of the body 3 as described above, the cover main body 2 is configured to cover the wiring device 4 together with the storage section 36. Here, the cover main body 2 is formed into a box shape with an open rear surface.

The cover body 2 has a main wall 200, a first side wall 201, a second side wall 202, and a bottom wall 203. The main wall portion 200 covers the wiring device 4 from at least one of the front and the top. The first side wall portion 201 is adjacent to the main wall portion 200 and covers the wiring device 4 from the left side. The second side wall portion 202 is adjacent to the main wall portion 200 and covers the wiring device 4 from the right side. In this embodiment, the main wall portion 200 has a curved portion 204 (see FIG. 2) and a flat portion 205 (see FIG. 2). The curved portion 204 is a portion that is curved obliquely upward and convex along the front surface of the storage portion 36 . The flat portion 205 is a portion formed in a flat plate shape that is continuous with the lower end edge of the curved portion 204 and is perpendicular to the front-rear direction. The bottom wall portion 203 is adjacent to the main wall portion 200 and covers the wiring fixture 4 from below. A pull-out portion 231 for pulling out the cable 80 (see FIG. 3) is formed in the bottom wall portion 203. In this embodiment, since the wiring device 4 is a two-port outlet, the cover main body 2 is formed with a pair of drawer portions 231 arranged in the left-right direction. Each drawer portion 231 is an opening portion that is open to the rear when viewed from below.

Here, each of the first side wall section 201 and the second side wall section 202 is substantially perpendicular to the main wall section 200. That is, each of the first side wall part 201 and the second side wall part 202 is substantially perpendicular to the left-right direction. However, "orthogonal" as used in the present disclosure includes not only a state in which they intersect strictly at 90 degrees, but also a state in which they intersect substantially at right angles within a certain degree of error. Further, the bottom wall portion 203 is substantially orthogonal to the vertical direction. However, the bottom wall portion 203 is not strictly parallel to the horizontal plane, and the lower surface of the bottom wall portion 203 is slightly inclined diagonally forward. Furthermore, the curved portion 204 is slanted toward the front, giving the upper surface of the cover body 2 a slope that prevents rainwater from accumulating.

Further, the dimensions of the cover main body 2 when viewed from the front are approximately the same as the dimensions of the body 3, and when the wiring device device 10 is viewed from the side in the left and right direction, the body 3 and the cover main body 2 have a sense of unity. It is elevated.

Further, the cover main body 2 has a pair of bearing portions 28 . A bearing hole 273 into which the shaft body 7 is inserted is formed in each of the pair of bearing parts 28, and the pair of bearing parts 28 hold the shaft body 7 held by the support part 32 of the body 3. do. The shaft body 7 is arranged on the rotating shaft 300. According to this configuration, the cover main body 2 is held with respect to the body 3 so as to be rotatable about the rotation shaft 300. The pair of bearing portions 28 will be described in detail in the section “(2.5) Details of hinge structure”.

By the way, the wiring device case 1 according to the present embodiment has a function of fixing the cover body 2 in the closed position by the lock mechanism 5 (see FIG. 1) and the lock member 6 (see FIG. 2). Therefore, the cover body 2 is formed with an operation hole 271 for operating the lock mechanism 5 and a regulation hole 272 for attaching the lock member 6.

The operation hole 271 is formed at the center in the left-right direction at the lower end of the main wall 200 of the cover body 2 . The operation hole 271 is a through hole 27 through which the lock pin 51 is inserted. The lock pin 51 is a pin for operating the lock mechanism 5. The lock mechanism 5 is configured to be switchable between a locked state in which the cover body 2 is fixed in the closed position and an unlocked state in which the cover body 2 is allowed to move from the closed position to the open position.

Specifically, as shown in FIGS. 4 and 5, the lock pin 51 is a round bar-shaped member that is long in the front-rear direction, and penetrates the cover body 2 by being inserted into the operation hole 271. A lock plate 52 is fixed to an end (rear end) of the lock pin 51 that protrudes from the rear surface of the cover main body 2 . The lock plate 52 is configured to be rotatable within a range of approximately 90 degrees around the axis of the lock pin 51. A head 53 is formed at an end (front end) of the lock pin 51 that protrudes from the front surface of the cover body 2 . A groove having a shape corresponding to a special jig (key) is formed in the head 53. Therefore, by operating the head 53 of the lock pin 51 using a dedicated jig, the lock pin 51 can be rotated together with the lock plate 52.

Here, the lock plate 52 constitutes the lock mechanism 5 together with the lock receiving portion 38 of the body 3. The lock receiving portion 38 is formed at a position corresponding to the lock plate 52 when the cover body 2 is in the closed position. Therefore, by rotating the lock plate 52 with the cover main body 2 in the closed position, the lock plate 52 is inserted into and removed from the lock hole 381. When the lock plate 52 is inserted into the lock hole 381, the lock plate 52 is caught on the lock receiver 38, so movement of the cover body 2 from the closed position to the open position is restricted, and the cover body 2 is fixed in the closed position. be done. In other words, the state in which the lock plate 52 is inserted into the lock hole 381 corresponds to the locked state. Further, a state in which the lock plate 52 is removed from the lock hole 381 corresponds to an unlocked state. When the lock plate 52 is inserted into and removed from the lock hole 381, a click feeling (feeling of moderation) is generated by the leaf spring 382.

The regulation hole 272 is formed at the rear end of the lower end of the second side wall 202 of the cover body 2 . The regulation hole 272 is a through hole 27 through which the lock member 6 (see FIG. 2) is passed. The lock member 6 is, for example, a general lock such as a padlock. When the lock member 6 is inserted into the regulation hole 272, the periphery of the hole contacts the lock member 6, thereby regulating the movement of the cover body 2 from the closed position to the open position. The lock member 6 may or may not be included in the components of the wiring device case 1. In FIG. 2, the lock member 6 is represented by an imaginary line (double-dashed line).

Specifically, as shown in FIG. 2, the lock member 6 is attached to the wiring device case 1 with its shackle portion passing through the second side wall portion 202 of the cover body 2 and the guide protrusion 39 of the body 3. By this, the cover body 2 is fixed in the closed position. That is, the lock member 6 is locked by passing the shackle portion through the regulation hole 272 of the cover body 2 and the through hole 391 of the guide protrusion 39, thereby regulating the movement of the cover body 2 from the closed position to the open position, that is, the cover body 2 is locked. Lock main body 2. On the other hand, when the lock member 6 is unlocked and removed from the wiring device case 1, the restriction on movement of the cover body 2 from the closed position to the open position is released, and the cover body 2 is unlocked.

By the way, in this type of outlet device with a cover 20, if the plug 8 is pulled out while the cover body 2 is in the closed position, the plug 8 will get caught on the cover body 2, causing the plug 8 to be pulled out halfway ( (hereinafter referred to as a "half-finished state"). In the incomplete state, the plug 8 is not completely removed from the wiring device 4, so the electrical connection between the plug 8 and the wiring device 4 may continue, and in that case, compared to the normal connection state, The electrical resistance (contact resistance) between the plug 8 and the wiring device 4 may increase.

In the wiring device device 10 according to the present embodiment, the wiring device 4 having a function of preventing the plug 8 from being removed is employed in order to reduce the occurrence rate of such incomplete states. The plug 8 retaining function can be achieved, for example, by rotating the plug 8 around an axis along the insertion direction, or by hooking a protrusion provided on the wiring device 4 onto the plug 8. This is realized by a method of preventing the plug 8 from coming off. However, even in this type of wiring device device 10, in a situation where the plug 8 retaining function is not used correctly, for example, when a person's foot gets caught in the cable 80, the plug 8 can be removed from the wiring device 4. There is a possibility that it will come off.

Therefore, in this embodiment, as shown in FIG. 3, a space S1 is provided that is sufficient for the pair of blades 81 and the pin 82 of the plug 8 to completely come out from the wiring device 4 when the cover body 2 is in the closed position. is located between the cover main body 2 and the body 3 and below the connection surface 411. Therefore, in the wiring device device 10, even if the plug 8 is pulled out from the wiring device 4 when a person's foot gets caught in the cable 80 while the cover body 2 is in the closed position, the plug 8 can be overcome and the occurrence of a half-finished state can be avoided.

(2.3) Waterproof Plate The waterproof board 9 is arranged so as to be sandwiched between the rear surface of the body 3 and the construction surface (wall surface), and is inserted into the storage section 36 from the second opening 362 on the rear surface of the body 3. Prevent rainwater from entering the space. The waterproof plate 9 is formed into a rectangular plate shape that is one size smaller than the frame 35 of the body 3, as shown in FIGS. 4 and 5. The waterproof plate 9 is made of, for example, soft vinyl chloride resin. An annular groove 91 is formed on the front surface of the waterproof plate 9. The groove 91 is formed so as to surround at least a region of the front surface of the waterproof plate 9 that faces the second opening 362 . By fitting the rib 352 formed on the rear surface of the frame 35 into the groove 91, rainwater is prevented from entering the second opening 362.

Furthermore, a rib 92 is formed on the rear surface of the waterproof plate 9 so as to substantially surround the entire circumference of the area where the groove 91 is formed. The ribs 92 prevent rainwater from entering the space between the waterproof board 9 and the construction surface. Furthermore, a wire passage hole 93 for wire passage is formed in the waterproof plate 9 at a position corresponding to the second opening 362 . In the waterproof plate 9, a pair of attachment holes 94 for passing attachment screws are formed at positions corresponding to the pair of attachment holes 353.

According to the above configuration, the wiring device device 10 is attached to a construction surface with a pair of mounting screws, with the body 3 holding the wiring device 4 combined with the waterproof plate 9. At this time, the electric wire pulled out from the construction surface is introduced into the internal space of the storage part 36 through the wire passage hole 93 and the second opening 362, and is connected to the terminal part of the wiring device 4 in the storage part 36. When the cover main body 2 attached to the body 3 is closed, that is, when the cover main body 2 is in the closed position, the pair of mounting screws are covered by the cover main body 2 together with the wiring device 4.

(2.4) Details of Wiring Equipment Cover Hereinafter, a more detailed configuration of the cover 20 according to the present embodiment will be described with reference to FIGS. 6 to 8B.

The cover body 2 integrally includes a first molded body 21 and a second molded body 22. The first molded body 21 is made of a first resin containing a glitter pigment. The second molded body 22 is made of a second resin that does not contain a glittering pigment. In this embodiment, the first molded body 21 and the second molded body 22 are integrally molded by two-color molding (double molding). The first molded body 21 includes a main plate 210 and a first side plate. 211 and a second side plate 212 are integrated. The main plate 210 covers the wiring device 4 from at least one of the front and the top. The first side plate 211 is configured to protrude rearward from the left edge of the main plate 210. That is, the first side plate 211 is adjacent to the main plate 210 and covers the wiring device 4 from the left side. The second side plate 212 is configured to protrude rearward from the right edge of the main plate 210. That is, the second side plate 212 is adjacent to the main plate 210 and covers the wiring device 4 from the right side. An opening 213 that opens downward when viewed from the front is formed in the center of the lower end of the main plate 210 in the left-right direction.

The second molded body 22 integrally includes a bottom plate 23, a pair of vertical frame portions 24, a rising portion 25, and a reinforcing portion 26. The bottom plate 23 covers the wiring device 4 from below. The pair of vertical frame portions 24 protrude rearward from the rear end edges of each of the first side plate 211 and the second side plate 212. The pair of vertical frame portions 24 are provided over the entire length of the first molded body 21 in the vertical direction. As shown in FIG. 6, the rising portion 25 is formed in a shape that rises upward from the front end edge and both left and right end edges of the bottom plate 23. The rising portion 25 includes an exposed portion 251 that is exposed forward through the opening 213. The portion of the rising portion 25 other than the exposed portion 251 is joined to the first molded body 21 so as to overlap with the first molded body 21 from the back side (the surface facing the body 3). The reinforcing part 26 is a band-shaped member that connects the upright part 25 and the pair of vertical frame parts 24, and overlaps the first molded body 21 from the back surface (the surface facing the body 3). It is combined with the first molded body 21.

In other words, regarding the main wall portion 200 of the cover body 2, only the center portion in the left-right direction at the lower end portion is constituted by the second molded body 22 (exposed portion 251), and the other portions are constituted by the first molded body 21. (main plate 210). Similarly, with respect to the first side wall portion 201, only the rear end portion is composed of the second molded body 22 (vertical frame portion 24), and the other portion is composed of the first molded body 21 (first side plate 211). It is configured. Regarding the second side wall portion 202, only the rear end portion is composed of the second molded body 22 (vertical frame portion 24), and the other portion is composed of the first molded body 21 (second side plate 212). There is. The bottom wall portion 203 is composed of the second molded body 22 (bottom plate 23).

In this embodiment, the first resin constituting the first molded body 21 is a flame-retardant resin containing a glitter pigment. The "glitter pigment" as used herein is a pigment that is made of, for example, metal powder (metal flakes), mica, titanium oxide, or glass flakes, and exhibits metallic luster or pearl-like luster. In this embodiment, metal powder (for example, aluminum flakes) is used as a glittering pigment, and the first resin constituting the first molded body 21 is colored with a metallic color. In other words, the first resin constituting the first molded body 21 is a so-called dope-dyed (raw material colored) resin that is colored at the raw material stage before molding by containing a bright pigment in a base material made of a translucent resin. It is. By using this type of dyed resin, it is possible to color the finished product (first molded body 21) with a metallic color or the like even without painting. The base material of the first resin, which is a flame-retardant resin, is, for example, polycarbonate, ASA resin, PC/ABS alloy resin, or ABS resin.

Further, the second resin constituting the second molded body 22 is a flame-retardant resin that does not contain a glittering pigment. In this embodiment, the second resin constituting the second molded body 22 is a so-called solid color undyed resin that does not contain a glittering pigment but only contains a colored pigment. By using this type of base-dyed resin, it is possible to color the finished product (second molded body 22) in a solid color even without painting. The base material of the second resin, which is a flame-retardant resin, is, for example, polycarbonate, ASA resin, PC/ABS alloy resin, or ABS resin. In this embodiment, the base material of the second resin is a different resin from the base material of the first resin.

In addition, "flame-retardant resin" as used in the present disclosure refers to resin that is not flammable but flame-retardant when classified into combustible and flame-retardant (including non-flammable). It is. In this embodiment, the cover main body 2 has flame retardancy of UL94 V-2 or higher. "UL94" is a flame retardant evaluation standard established by UL (Underwriters Laboratories). There are six grades in the UL94 standard: "HB" for the horizontal combustion test, "V-2", "V-1", "V-0", "5VA", and "5VB" for the vertical combustion test. There is a grade. Of these six grades, "HB" has the lowest flame retardancy, followed by "HB", "V-2", "V-1", "V-0", "5VB", and "5VA". becomes more sexual. In other words, the cover main body 2 (the first molded body 21 and the second molded body 22) having flame retardancy of UL94 V-2 or higher is classified as "V-2", "V-1", "V-1", "HB", etc. It has a flame retardancy of "V-0", "5VB", or "5VA". A resin having flame retardancy of UL94 V-2 or higher has the property of burning while exposed to flame in the atmosphere, but extinguishing when removed from the flame (self-extinguishing property). The flame-retardant resin that is the material of the cover body 2 (the first molded body 21 and the second molded body 22) has a flame retardant rating of "V-2" or higher according to the UL94 standard when the thickness of the sample is, for example, 2.5 mm. It is preferable that the

Further, in the first molded body 21, at least one surface (that is, the surface) of each of the first side plate 211 and the second side plate 212 on the side opposite to the body 3 is formed of an uneven surface that is textured (embossed). The "texturing" herein refers to a process of forming a fine uneven wrinkle pattern (texture) on the surface of the first molded body 21 when the first molded body 21 is molded. In the present embodiment, in the first molded body 21, the left side surface of the first side plate 211, the right side surface of the second side plate 212, and the front and top surfaces of the main plate 210 are made of textured uneven surfaces. Thereby, even if the first molded body 21 is unpainted (without painting), it is possible to realize a texture similar to that of painting due to the fine irregularities on the surface.

Further, if the first molded body 21 is a silver-like metallic color and the second molded body 22 is a solid color such as gray or black, the first molded body 21 will stand out compared to the second molded body 22. Become. In particular, by adopting the same solid color as the second molded body 22 for the body 3, the hinge structure, etc., which will be described later, provided at the rear end of the wiring device case 1 becomes less noticeable, making it sharper. You can achieve a beautiful appearance.

By the way, the cover main body 2 has at least one (four in this embodiment) through holes 27. These through holes 27 are both provided in the second molded body 22 of the first molded body 21 and the second molded body 22. That is, all the through holes 27 are formed in the second molded body 22, and no through holes 27 are formed in the first molded body 21. The term "through hole" used herein means a hole that is formed to pass through the second molded body 22 and whose peripheral edge of the opening surface is formed in a closed loop shape. In other words, a hole whose opening surface has a discontinuous periphery, that is, a part of the periphery is open, such as the pull-out portion 231, for example, is not included in the term "through-hole" herein.

In this way, by forming the through hole 27 only in the second molded body 22 that does not contain the glitter pigment, for example, even if a weld line occurs around the through hole 27, the weld line is less noticeable. There are advantages. That is, when the cover body 2 having the through hole 27 is molded, for example, by injection molding, when molding the cover body 2, a plurality of mold pieces are combined, and a cavity formed between the plurality of mold pieces is removed. Molten resin is injected into the inside from the gate part. Here, the core for forming the through hole 27 becomes an obstacle, causing the molten resin to separate into two parts, and the tips (flow fronts) of the separated molten resin join together around the core, creating a weld line. may occur. If such a weld line were to occur in the first molded body 21, the weld line would be formed depending on the orientation of the glitter pigment because the molten resin (first resin) contains a glitter pigment with directionality. may be noticeable in appearance. On the other hand, in the second molded body 22 that does not contain a glittering pigment, the colored pigment contained in the molten resin (second resin) has a substantially spherical shape and has no directionality, so the weld line is less noticeable in appearance.

In this embodiment, since the through hole 27 is provided only in the second molded body 22 of the first molded body 21 and the second molded body 22, the through hole 27 is provided in the molded cover main body 2 for the above reason. This has the advantage that the weld line around the hole 27 is less noticeable.

The plurality of through holes 27 include an operation hole 271, a regulation hole 272, and a pair of bearing holes 273. In this embodiment, all four through holes 27 are formed in the second molded body 22. The operation hole 271 is formed in the exposed portion 251 of the rising portion 25 of the second molded body 22 . The regulation hole 272 is formed at the lower end of one (the right side in this embodiment) of the pair of vertical frame portions 24 in the second molded body 22 . The pair of bearing holes 273 are formed at the upper end portions (bearing portions 28) of the pair of vertical frame portions 24.

Furthermore, in this embodiment, the first molded body 21 does not have a uniform thickness over its entirety, but the thickness changes partially. Here, at least a portion of the main plate 210 is set to be thicker than the first side plate 211 and the second side plate 212.

Specifically, as shown in FIGS. 8A and 8B, a thickness t2 of a region Z1 of the main plate 210 corresponding to the curved portion 204 (see FIG. 2) is different from that of the other region (for example, the flat portion 205 (see FIG. 2). (t1<t2). The thickness t1 of the area of the main plate 210 corresponding to the flat portion 205 (see FIG. 2) is the same as the thickness t1 of the first side plate 211 and the second side plate 212. FIG. 8B is an enlarged view of a main part taken along the line AA in FIG. 8. Here, the thickness t1 of the first side plate 211, the second side plate 212, etc. is preferably 2 mm to 3 mm, for example. In this case, it is preferable that the thickness t2 of the region Z1 of the main plate 210 is larger than the thickness t1 by, for example, several percent to more than ten percent of the thickness t1.

In this embodiment, as shown in FIG. 8A, the gate mark 214 of the first molded body 21 is located at the center of the upper end of the main plate 210 in the left-right direction. Here, the gate trace 214 is provided on the rear surface of the main plate 210. The gate trace 214 is a portion corresponding to a gate portion, that is, a portion that becomes an inlet of resin (first resin) when it flows into the mold during molding of the first molded body 21 .

In such a configuration, when molding the first molded body 21, the molten resin injected from the gate portion basically flows through the mold into each of the main plate 210, the first side plate 211, and the second side plate 212. , flows from the upper end to the lower end. Here, it would be ideal if the molten resin could reach the lower ends of the main plate 210, the first side plate 211, and the second side plate 212 substantially simultaneously, since molding defects such as flow marks and weld lines, for example, would be less likely to occur. However, the upper half of the main plate 210 (region Z1 corresponding to the curved part 204) is curved, and the main plate 210 has a larger area from the upper end to the lower end than the first side plate 211 and the second side plate 212. The distance becomes longer. In addition, due to various circumstances, the timing at which the molten resin reaches the lower end may vary between the main plate 210, the first side plate 211, and the second side plate 212. For example, when the molten resin reaches the lower end of the first side plate 211 and the second side plate 212 before the main plate 210, the molten resin wraps around from the first side plate 211 and the second side plate 212 to the main plate 210, causing, for example, flow marks and Molding defects such as weld lines may occur.

Therefore, in the present embodiment, in the first molded body 21, the thickness t2 of at least a portion of the main plate 210 is made relatively larger than the thickness t1 of the first side plate 211 and the second side plate 212. The flow rate of the molten resin during molding of the molded body 21 is controlled. In short, if the thickness t2 of the main plate 210 becomes larger than the thickness t1 of the first side plate 211 and the second side plate 212, the flow velocity of the molten resin in the main plate 210 will improve. As a result, the timing at which the molten resin reaches the lower end can be aligned between the main plate 210, the first side plate 211, and the second side plate 212, and molding defects such as flow marks and weld lines are less likely to occur.

Further, in the present embodiment, the gate marks 214 of the first molded body 21 are provided on the main plate 210, but the gate marks 214 of the first molded body 21 are not limited to this example. Traces may also be provided.

(2.5) Details of Hinge Structure Next, the hinge structure for rotatably supporting the cover main body 2 with respect to the body 3 will be described in detail with reference to FIGS. 9A to 12. FIG. 9A is a cross-sectional view of the upper end of the wiring device case 1 viewed from the front and cut along a plane orthogonal to the front-rear direction. 9B is an enlarged view of region Z1 in FIG. 9A, and FIG. 9C is an enlarged view of region Z2 in FIG. 9A.

The cover body 2 is supported by the body 3 by a hinge structure so as to be rotatable between a closed position and an open position about a rotation shaft 300 located at the upper end of the body 3. The hinge structure includes a support portion 32 of the body 3, a pair of bearing portions 28 of the cover main body 2, and a shaft body 7.

The shaft body 7 is a round bar-shaped member disposed on the rotating shaft 300. In this embodiment, the shaft body 7 is made of metal. A recess 70 is formed on the outer circumferential surface of the shaft 7 at the center of the shaft 7 in the axial direction, over the entire circumference. Since the shaft body 7 is separate from the resin body 3 and the cover body 2, the material of the shaft body 7 can be made of metal. The diameter of the shaft body 7 can be made smaller than that of the shaft body.

The support portion 32 has a holding hole 34 through which the shaft body 7 passes. The holding hole 34 penetrates the support portion 32 along the axial direction (horizontal direction) of the rotating shaft 300. The width of the support portion 32 in the left-right direction is smaller than the width of the body 3 in the left-right direction. The support portion 32 is provided at the upper end of the body 3 and at the center of the body 3 in the left-right direction. In this embodiment, the support portion 32 is arranged within a water passage groove 31 (see FIG. 10) formed in the body 3.

Specifically, the upper end of the body 3 is formed with the water passage groove 31 having an opening on the upper surface as described above. As shown in FIG. 10, the water passage groove 31 has a pair of side surfaces 311 facing each other in the front-rear direction. The water passage groove 31 is formed at the upper end of the body 3, extending substantially between both ends in the left-right direction. Furthermore, the bottom surface 312 of the water passage groove 31 is inclined with respect to the horizontal plane so as to become lower toward both ends in the left and right direction. As a result, water W1 such as rainwater (see FIG. 12) that has entered through the gap between the body 3 and the cover main body 2 is guided to both sides of the body 3 in the left and right direction through the water passage groove 31.

The support portion 32 is located between a pair of side surfaces 311 of the water passage groove 31 . The support portion 32 is located at the rear end within the water passage groove 31 so that a gap is formed between the support portion 32 and the front side surface 311 of the pair of side surfaces 311 . Further, an opening connected to the holding hole 34 is provided in the center portion of the rear surface of the support portion 32 in the left-right direction (see FIG. 5). Here, the support portion 32 is formed to protrude upward from the bottom surface 312 of the water channel 31, but this configuration is not essential. For example, there may be a gap between the bottom surface 312 and the support portion 32. It's okay.

The shaft body 7 is inserted into the holding hole 34. The width of the support portion 32 in the left-right direction is shorter than the entire length of the shaft body 7, and both ends of the shaft body 7 protrude from the support portion 32 when the shaft body 7 is inserted into the holding hole 34.

A protrusion 340 is provided on the inner peripheral surface of the holding hole 34 at a portion corresponding to the recess 70 of the shaft 7 when the shaft 7 is inserted into the holding hole 34 . By inserting the protrusion 340 into the recess 70, the shaft body 7 is positioned within the holding hole 34 in the axial direction (horizontal direction) of the rotating shaft 300. That is, when the protrusion 340 is inserted into the recess 70, the protrusion 340 contacts the side surface 701 of the recess 70 (see FIG. 9C), so that the first orientation along the axial direction (horizontal direction) of the rotating shaft 300 is The protrusion 340 restricts the movement of the shaft body 7 to. In the present embodiment, the protrusion 340 contacts the left side surface 701 of both left-right side surfaces of the recess 70 formed in the shaft body 7, so that the shaft body 7 moves to the right as the "first direction". movement is regulated.

In this embodiment, the direction in which the shaft body 7 is inserted into the holding hole 34 is determined when the wiring device case 1 is assembled. For example, the shaft body 7 is inserted from the right side of the holding hole 34 to the left side. inserted. Here, if a direction opposite to the first direction (rightward) is defined as a "second direction", the shaft body 7 is inserted into the holding hole 34 in the second direction (leftward). It turns out. The right end surface of the protrusion 340 is an inclined surface 341 that is inclined with respect to the axial direction of the rotating shaft 300 (see FIG. 9C). The inclined surface 341 is inclined so that the amount of protrusion of the protrusion 340 from the inner circumferential surface of the holding hole 34 decreases as it approaches the right edge. Thereby, when the shaft body 7 is inserted into the holding hole 34 from the right side, the shaft body 7 comes into contact with the inclined surface 341 of the projection 340, so that the shaft body 7 easily rides on the projection 340. Further, the left end surface of the protrusion 340 is a regulating surface 342 that is orthogonal to the rotation axis 300. Therefore, when the protrusion 340 is inserted into the recess 70, the restriction surface 342 contacts the side surface 701 of the recess 70, thereby restricting movement of the shaft body 7 in the first direction (rightward).

Further, the support portion 32 further includes a plurality of convex portions 343 that protrude from the inner circumferential surface of the holding hole 34 (see FIG. 9A). In this embodiment, a pair of convex portions 343 are formed at both ends of the holding hole 34 in the left-right direction and at positions slightly closer to the center. When the shaft body 7 is inserted into the holding hole 34, the tips of the pair of protrusions 343 come into contact with the metal shaft body 7, so that the shaft body 7 is held in a state where the wobbling of the shaft body 7 is reduced. is supported by the support portion 32. In order to reduce rattling of the shaft body 7, the shaft body 7 may be knurled, but the knurling process is expensive. In this embodiment, by forming the convex portion 343 on the inner circumferential surface of the holding hole 34, a structure for reducing rattling of the shaft body 7 can be realized at low cost.

The pair of bearings 28 are provided at both ends of the upper end of the cover main body 2 in the left-right direction. The pair of bearing parts 28 are located one each on both sides of the support part 32 of the body 3 in the left-right direction. In this embodiment, the pair of bearing portions 28 are formed at the upper end portions of the pair of vertical frame portions 24 of the second molded body 22 . The pair of bearing portions 28 have a pair of bearing holes 273 through which the shaft body 7 passes. The bearing hole 273 passes through the bearing portion 28 along the axial direction (left-right direction) of the rotating shaft 300.

When the shaft body 7 is inserted into the holding hole 34 and the pair of bearing holes 273, the center piece 71 of the shaft body 7 is held by the support part 32, and the tip piece 72 and the base end piece 73 of the shaft body 7 are held together. It is held by the bearing part 28 of. The center piece 71 is a central portion of the shaft body 7 in the longitudinal direction (left-right direction). The tip piece 72 is a portion that protrudes from the center piece 71 in the second direction (leftward), and protrudes from the support portion 32 in the second direction (leftward). The tip piece 72 is held by the left bearing part 28 by being inserted into a bearing hole 273 formed in one of the pair of bearing parts 28 (here, the left one). The base end piece 73 is a portion that protrudes from the center piece 71 in a first direction (rightward), and protrudes from the support portion 32 in a first direction (rightward). The base end piece 73 is held by the right bearing part 28 by being inserted into a bearing hole 273 formed in one (here, the right side) bearing part 28 of the pair of bearing parts 28 . At least one of the support portion 32 and the pair of bearing portions 28 is configured to hold the shaft body 7 rotatably about the rotating shaft 300.

Here, as shown in FIG. 9B, the outer diameter d2 of the tip piece 72 is smaller than the outer diameter d1 of the center piece 71. Further, the inner diameter d3 of the left bearing hole 273 into which the tip piece 72 is inserted is smaller than the outer diameter d1 of the center piece 71. Furthermore, the inner diameter d3 of the left bearing hole 273 into which the tip piece 72 is inserted is greater than or equal to the outer diameter d2 of the tip piece 72. That is, the relationship "d2≦d3<d1" is established between the outer diameters d1 and d2 and the inner diameter d3 shown in FIG. 9B. In other words, a step is formed on the outer peripheral surface of the shaft body 7 between the center piece 71 and the tip piece 72 to make the outer diameter d2 of the tip piece 72 smaller than the outer diameter d1 of the center piece 71. . Further, the inner diameter of the right bearing hole 273 into which the base end piece 73 is inserted is larger than the outer diameter d1 of the center piece 71. In other words, the pair of bearing holes 273 have different inner diameters.

Therefore, when the shaft body 7 is inserted in the second direction (leftward) into the holding hole 34 and the pair of bearing holes 273 during assembly of the wiring device case 1, the center piece 71 and the tip piece The movement of the shaft body 7 in the second direction is restricted by the step between the shaft body 72 and the shaft body 72 . That is, the shaft body 7 is inserted in the second direction (to the left) with the holding hole 34 and the pair of bearing holes 273 aligned in a straight line along the rotating shaft 300. At this time, after the tip piece 72 is inserted into the bearing hole 273 of the left bearing part 28, the shaft body 7 is inserted into the bearing hole in the left bearing part 28 at the step between the center piece 71 and the tip piece 72. By contacting the periphery of 273, movement in the second direction (leftward) is restricted. In this state, the movement of the shaft body 7 in the first direction (rightward) is also restricted by the restriction surface 342 of the protrusion 340 coming into contact with the side surface 701 of the recess 70 as described above. . Therefore, movement of the shaft body 7 along the axial direction (left-right direction) of the rotating shaft 300 is restricted, and the shaft body 7 is prevented from coming off from the holding hole 34 and the pair of bearing holes 273.

As described above, since the shaft body 7 does not pass through the left bearing hole 273 of the pair of bearing holes 273, it is not essential that the bearing hole 273 pass through the bearing portion 28. That is, one of the pair of bearing holes 273 (here, the left side) may be a hole having a bottom instead of the through hole 27.

Here, in this embodiment, the inner diameters of the holding hole 34 and the pair of bearing holes 273 are both set to be larger than the outer diameter of the shaft body 7. Therefore, while positioning the shaft body 7 and preventing it from coming off, the shaft body 7 is more securely attached to the support portion 32 or the pair of bearing portions 28 than in a configuration in which the shaft body 7 is press-fitted into the support portion 32 or the pair of bearing portions 28. Damage can be reduced. Therefore, the wiring device case 1 is less likely to be damaged.

By the way, the wiring device case 1 according to the present embodiment includes a protruding piece 33 as a structure for holding (temporarily fixing) the cover main body 2 in the open position. The protruding piece 33 is provided on the body 3.

The protruding piece 33 has a cantilever shape. The protruding piece 33 protrudes from at least one of both end surfaces of the support portion 32 in the longitudinal direction (left-right direction) of the water passage groove 31 . In this embodiment, a pair of protruding pieces 33 are provided, and the pair of protruding pieces 33 protrude from both end surfaces of the support portion 32 . As shown in FIG. 10, the pair of protruding pieces 33 are located below the shaft body 7, and are arranged so that their upper surfaces face the outer circumferential surfaces (lower surfaces) of the pair of bearings 28. Each of the pair of protruding pieces 33 is configured to be elastically deformable so that at least its tip portion can move in the vertical direction.

Each of the pair of protruding pieces 33 has a regulating protrusion 331 that protrudes upward from its upper surface. The regulating protrusion 331 is formed in a substantially triangular shape with hypotenuses on both sides in the front and rear directions when viewed from one axial direction of the rotating shaft 300. On the other hand, each of the pair of bearing parts 28 has a hook part 281 on a part of its outer peripheral surface in the rotational direction of the cover body 2. The hook portion 281 is formed in a substantially triangular shape with hypotenuses on both sides in the rotation direction of the cover main body 2 when viewed from one axial direction of the rotation shaft 300 . Here, the pair of regulating protrusions 331 on the pair of protruding pieces 33 are located around the rotating shaft 300 and on the locus of the hook portion 281 when the cover body 2 moves from the closed position to the open position. .

When the cover body 2 is in the open position, a portion of the protruding piece 33 (regulating protrusion 331) comes into contact with the hook portion 281 in the rotational direction of the cover body 2, thereby causing the cover body 2 to move to the closed position. to regulate. That is, as shown in FIGS. 10 and 11, when the cover body 2 is in the open position, a part of the protruding piece 33 (regulating protrusion 331) provided on the body 3 touches a part of the cover body 2 (the hook part 281). ), movement (rotation) of the cover main body 2 to the closed position is restricted. As a result, the cover body 2 is held in the open position.

Further, when the cover main body 2 moves from the open position to the closed position, a part of the protruding piece 33 (regulating protrusion 331) is pushed by the hook part 281 and elastically deforms in a direction away from the rotating shaft 300. Then, the restriction on movement of the cover body 2 to the closed position is released. That is, when the user closes the cover body 2 that is in the open position, as shown in FIG. By pressing , the protruding piece 33 is elastically deformed, and the tip of the protruding piece 33 moves downward. In FIG. 10, the tip of the protruding piece 33 in a downwardly moved state is shown by an imaginary line (two-dot chain line). As a result, the hook portion 281 of the cover body 2 passes over a portion of the protruding piece 33 (regulating protrusion 331), and the cover body 2 becomes movable to the closed position. In FIG. 10, the cover body 2 is shown by an imaginary line (two-dot chain line) after the hook portion 281 has climbed over the regulating protrusion 331 but before reaching the closed position. When the cover main body 2 reaches the closed position, the hook portion 281 separates from the regulating protrusion 331, and the protruding piece 33 returns to its original position (the position indicated by the solid line in FIG. 10) due to its elastic force. When the cover body 2 is in the closed position, the hook portion 281 is accommodated in the hole formed in the body 3, thereby avoiding interference with the body 3.

When the cover main body 2 moves from the closed position to the open position, a part of the protruding piece 33 (regulating protrusion 331) is attached to the hook part 281, similarly to when the cover main body 2 moves from the open position to the closed position. is pushed and elastically deforms in a direction away from the rotating shaft 300 (downward). As a result, the cover main body 2 becomes movable to the open position, and is held at the open position when the cover body 2 reaches the open position.

By the way, when the cover main body 2 is held in the open position, the projecting piece 33 of the body 3 receives the moment acting on the cover main body 2 due to the cover main body 2's own weight. Therefore, the elastic modulus of the protruding piece 33 is set to be relatively large so that the moment acting on the cover body 2 due to its own weight does not release the restriction on movement of the cover body 2 to the closed position. It is preferable. In this case, when the hook part 281 gets over the regulation protrusion 331, the protruding piece 33 becomes difficult to bend, so that the shaft body 7 is elastically deformed when the hook part 281 gets over the regulation protrusion 331. It is preferable to have. Thereby, when the hook portion 281 climbs over the regulating protrusion 331, both the protruding piece 33 and the shaft body 7 are bent, and the decrease in the amount of deflection of the protruding piece 33 can be compensated for.

Furthermore, in this embodiment, as shown in FIG. 12, a hook portion 281 is provided at a position facing the tip of the protruding piece 33. As a result, when the hook part 281 gets over the regulating protrusion 331, the hook part 281 pushes the tip of the protrusion piece 33, so compared to the case where the hook part 281 pushes the base end of the protrusion piece 33, The protruding piece 33 becomes easier to bend.
