(Embodiment 1)
A wiring device according to a first embodiment of the present invention will be described with reference to FIGS. In this wiring device, an outlet A compliant with the IEC standard to which a plug 200 provided on a power cord from a load device is detachably connected is provided on the front surface of the body 1 (outlet body); In a state where the container 1 of the outlet A is attached and the rear part of the container 1 is housed in an embedded box embedded in the construction surface with the opening on the front side communicating with the embedding hole opening in the construction surface And an attachment frame 110 (frame member) attached to the opening of the embedded box.

  As shown in FIGS. 2 and 3, the container 1 of the outlet A is a body 2 formed in a rectangular parallelepiped shape whose front surface is opened using a thermosetting synthetic resin (for example, urea resin) having excellent tracking resistance. And a cover 3 formed in the shape of a rectangular parallelepiped whose rear surface is opened using a synthetic resin (for example, polybutylene terephthalate = PBT) having elasticity and excellent tracking resistance. Here, the container 1 has a prescribed unit dimension to be described later.

  A pair of assembly claws 4 project from the left and right end faces of the body 2. On the other hand, shoulders 5 project from the left and right ends of the cover 3, and assembly pieces 6 project from the rear edge of each shoulder 5 toward the body 2. Each assembly piece 6 is formed with a pair of engagement holes 6a for engaging with the assembly claws 4 of the body 2 in an uneven manner. Thus, when the body 2 and the cover 3 are assembled, the cover 3 is brought close to the body 2 from the front side, and the assembly claw 4 is fitted into the engagement hole 6 a provided in the assembly piece 6. And are to be combined.

  The interior of the body 2 is divided into two internal spaces by a partition wall 7 provided in the middle in the longitudinal direction. The front end portion of the partition wall 7 projects forward from the opening surface of the body 2. In addition, a positioning protrusion 2a protruding forward is provided at an appropriate position on the peripheral wall of the body 2. The partition wall 7 and the positioning projection 2a engage with a recess (not shown) formed in the cover 3 when the body 2 and the cover 3 are coupled to prevent the cover 3 from rattling with the body 2. To do. In addition, a partition wall (not shown) is also formed in the cover 3, and when the body 2 and the cover 3 are joined, the partition wall 7 of the body 2 and the partition wall of the cover 3 are brought into contact with each other. The internal space is divided into two independent rooms.

  A blade receiving member 9 is accommodated in each of the left and right storage chambers 8 partitioned by the partition wall 7 inside the body 2. Each blade receiving member 9 includes a pair of spring pieces 9a facing each other, and a U-shaped connecting piece 9b that continuously and integrally couples between the two spring pieces 9a. A terminal piece 9c is formed integrally with the connecting piece 9b at the open end of the connecting piece 9b so as to protrude away from each other. The pair of spring pieces 9a are inclined so that the distance between them becomes narrower toward the upper side, and the distance between the upper ends of the pair of spring pieces 9a increases toward the upper side so that the pin terminals 204a and 204b on the plug 200 side can be easily inserted. It is inclined to. Each storage chamber 8 is provided with a pair of locking springs 10 so as to face a pair of terminal pieces 9c provided in the blade receiving member 9. The locking spring 10 is formed by bending one end portion of the belt plate in an S shape to form a contact piece 10a and bending the other end portion in a J shape to form a locking piece 10b. The contact piece 10a and the locking piece 10b are accommodated in the body 2 so as to face the terminal piece 9c.

  A wire insertion port 2b is formed on the rear wall of the body 2 so that an electric wire can be introduced between the locking spring 10 and the terminal piece 9c. When an electric wire is inserted from the side of the locking piece 10b between the locking spring 10 and the terminal piece 9c through the electric wire insertion port 2b, the electric wire is connected to the terminal piece 9c by the spring force of the contact piece 10a and the locking piece 10b. And the locking piece 10b bites into the electric wire so that the electric wire cannot be pulled out. Thus, since it can connect only by inserting an electric wire in the electric wire insertion port 2b, compared with the case where a screwed terminal etc. are used, a connection work becomes easy. Further, since two electric wires can be connected to each blade receiving member 9 arranged in each storage chamber 8, it is used as a feed wiring for connecting one electric wire to the power source side and the other electric wire to another outlet. For example, the wiring work of connecting a plurality of outlets in parallel is facilitated.

  Furthermore, a release button 11 is disposed in each storage chamber 8 so as to straddle a pair of lock springs 10 respectively facing a pair of terminal plates 9c provided in each blade receiving member 9. The release button 11 is disposed so as to be in contact with the locking piece 10 b of the both locking springs 10 and to be slidable along the rear wall of the body 2. The part where the release button 11 contacts the locking piece 10b is deviated from the part where the locking piece 10b holds the electric wire between it and the terminal piece 9c. Further, an operation hole 2c is formed in the rear wall of the body 2 at a portion corresponding to the release button 11, and when the release button 11 is pushed by inserting a tip of a minus driver into the operation hole 2c, the operation hole 2c is bitten into the electric wire. The lock piece 10b is bent away from the electric wire so that the electric wire can be pulled out. Here, it is common to use a single wire having an insulation coating as the electric wire, and the length of the insulation coating is important for obtaining the required connection strength against the drawing of the electric wire. On the rear surface, a groove-like gauge 2d indicating the length for exposing the core wire is provided. At the time of construction, the insulating coating is peeled off so as to expose the core wire corresponding to the length of the gauge 2d.

  On the other hand, one outlet portion 20 is formed on the front wall of the cover 3. The shape, size, and pole arrangement of the outlet portion 20 (socket) and the plug 200 that is detachably connected to the outlet portion 20 conform to the IEC standard (CEI / IEC 906-3). The shape, size, pole arrangement, etc. of the connector used for the SELV power supply (AC and DC 6V, 12V, 24V, 48V) are defined.

  As shown in FIGS. 5 and 6, the plug 200 is connected to the end of the electric wire 210 from the load device. The plug 200 includes a substantially columnar gripping part 201 (plug body), and a cylindrical fitting part 202 having a smaller diameter than the rear side is formed on the front end side of the gripping part 201. A fitting hole 203, which is recessed in a round hole shape, is opened on the front surface of the fitting portion 202, and a reference rib 205 indicating a reference position is formed on the inner peripheral surface of the fitting hole 203 in the plug insertion / removal direction (FIG. 5 ( b) in a direction perpendicular to the paper surface). Then, on the straight line that passes through the center position of the gripping part 201 and is orthogonal to the line segment connecting the center position and the reference rib 205, the position is symmetrical with respect to the center position in the axial direction of the gripping part 201. Two round rod-like pin terminals 204a and 204b extending along the line are arranged.

  Here, in the DC power supply plug 200, as shown in FIG. 6A, when the reference rib 205 is viewed on the upper side, the pin terminal 204a located on the right side is on the positive side, and the pin terminal 204b located on the left side is on the negative side. It is a pin terminal. In addition, on the inner peripheral surface of the fitting hole 203, an identification rib 206 for preventing misconnection that extends along the plug insertion / extraction direction protrudes at a position corresponding to the type of power source (direct current or alternating current and rated voltage). Has been. FIG. 6A shows the position of the identification rib 206 provided on the plug 200 for DC power supply. When the power supply voltage is DC6V, 12V, 24V, and 48V, the position of the reference rib 205 is the reference (0 °). As shown, the identification ribs 206 are formed one by one at the positions of 120 °, 150 °, 210 °, and 240 ° counterclockwise. FIG. 6B shows the position of the identification rib 206 provided on the AC power supply plug 200. When the power supply voltage is AC6V, 12V, 24V, and 48V, the counterclockwise rotation is based on the position of the reference rib 205, respectively. In addition, identification ribs 206 are formed one by one at 30 °, 60 °, 300 °, and 330 ° positions. Here, the plug shown in FIG. 5 is for DC48V, and an identification rib 206 is formed at a position of 240 ° counterclockwise with respect to the reference rib 205.

  On the other hand, as shown in FIGS. 3B and 4, the outlet portion 20 has the same shape and size as the front surface of the fitting portion 202 of the plug 200, and the fitting portion 202 is detachably connected. The plug insertion hole 21 is opened. From the bottom surface of the plug insertion hole 21, a columnar protrusion 22 inserted into the fitting hole 203 of the plug 200 is formed to protrude forward. Terminal insertion holes 23a and 23b into which the pin terminals 204a and 204b are respectively inserted open on the front surface of the protruding portion 22. The above-described blade receiving members 9 and 9 are accommodated inside the protrusion 22 so as to face the terminal insertion holes 23a and 23b, and the blades are inserted into the pin terminals 204a and 204b inserted through the terminal insertion holes 23a and 23b. The receiving members 9 and 9 are electrically connected.

  Further, a fitting groove 24 indicating a reference position is formed on the side peripheral surface of the protruding portion 22 along the plug insertion / extraction direction, and passes through the center position of the protruding portion 22 to connect the center position and the fitting groove 24. On the straight line orthogonal to the minute, the terminal insertion holes 23a and 23b are opened at positions symmetrical to the center position. Here, in the outlet portion 20 for DC power supply, as shown in FIG. 4A, the terminal insertion hole 23a located on the left side when the fitting groove 24 is viewed on the upper side corresponds to the positive-side pin terminal, The terminal insertion hole 23b located on the right side corresponds to the pin terminal on the negative electrode side.

  Further, on the side peripheral surface of the protruding portion 22, a fitting for preventing erroneous connection in which the identification rib 206 of the corresponding plug 200 is fitted at a position corresponding to the type of power supply (DC or AC, and rated voltage). A groove 25 (an erroneous connection preventing groove) is formed. 4A shows the position of the fitting groove 25 provided in the outlet portion 20 for DC power supply. When the power supply voltage is DC6V, 12V, 24V, and 48V, the position of the fitting groove 24 is shown. With reference to (0 °), fitting grooves 25 are formed one by one at positions 120 °, 150 °, 210 °, and 240 ° clockwise. FIG. 4B shows the position of the fitting groove 25 provided in the outlet portion 20 for AC power supply. When the power supply voltage is AC6V, 12V, 24V, 48V, the position of the fitting groove 24 is shown respectively. As a reference (0 °), fitting grooves 25 are formed one by one at positions of 30 °, 60 °, 300 °, and 330 ° clockwise. Here, the outlet portion 20 shown in FIGS. 1 to 3 is for DC48V, and the fitting groove 25 is formed at a position of 240 ° clockwise with respect to the position of the fitting groove 24. Thus, in the outlet portion 20, the fitting groove 25 into which the identification rib 206 provided in the plug 200 is engaged is formed at a position corresponding to the power supply voltage on the side peripheral surface of the protruding portion 22. The plugs 200 having different supply voltages can be prevented from being plugged in and connected to the outlet portion 20 depending on the positions of 206 and the fitting groove 25, and a power supply suitable for the load device 60 can be supplied.

  Thus, when the fitting portion 202 of the plug 200 suitable for the outlet portion 20 is inserted into the plug insertion hole 21, the protruding portion 22 is inserted into the fitting hole 203 of the fitting portion 202, and the fitting is performed. The reference rib 205 and the identification rib 206 provided on the inner peripheral surface of the portion 202 are engaged with the fitting grooves 24 and 25 of the protrusion 22, respectively. At this time, the pin terminals 204a and 204b inserted into the protrusion 22 through the terminal insertion holes 23a and 23b of the protrusion 22 are electrically connected to the blade receiving members 9 and 9, respectively. The plug 200 is held in a state of being connected to the outlet portion 20 by the elastic contact force with which the blade receiving members 9 and 9 elastically contact 204b. In the outlet portion 20, since the front surface of the protruding portion 22 is in a position retracted from the front surface of the container body 1, the protruding amount of the plug 200 connected to the outlet portion 20 from the front surface of the container body 1 can be reduced.

  The container 1 of the outlet A is attached to a plate 100 which will be described later, and a pair of attachment claws 3a project from the shoulder portions 5 provided on both sides of the cover 3 so as to be coupled to the plate 100. ing. The front end of the mounting claw 3a is inclined so that the amount of protrusion from the shoulder 5 becomes smaller toward the front.

  In order to embed the outlet A in the construction surface, a plate 100 shown in FIGS. 7 to 9 is used. The plate 100 is composed of a plate frame 110 that holds the container 1 and a decorative plate 120 that covers the plate frame 110 and is applied with good appearance. The plate frame 110 includes a synthetic resin and a metal. The plate frame 110 made of synthetic resin is insulative, and the left ends of the pair of frame pieces 113a and 113b (the upper ends of FIG. 9 (a)) and the right ends (the lower ends of FIG. 9 (a)). ) Are continuously and integrally joined by the horizontal pieces 112 so that a rectangular opening window 111 exposing the front surface of the container 1 is formed in a vertically long rectangular frame shape having a central portion. On the rear surface side of both side edges along the longitudinal direction of the opening window 111, a strip-like fixed beam portion 114 and a movable beam portion 115 are provided so as to face each other.

  The movable beam portion 115 is continuously and integrally connected to the frame piece 113b via a connecting portion 116 extending in the longitudinal direction of the movable beam portion 115 at both ends in the longitudinal direction, and two intermediate portions are connected to the movable beam portion 115. It is continuously and integrally connected to the frame piece 113b via a bridge portion 117 in the orthogonal direction. Moreover, the part between each connection part 116 and each bridge | bridging part 117 and between both the bridge | bridging parts 117 becomes the slit 118a-118c penetrated in the front and back. The synthetic resin forming the plate frame 110 is flexible, and the movable beam portion 115 and the connecting portion 116 are flexible. The slits 118a and 118c on both sides are formed in an L shape, and the slit 118b in the middle is formed in a straight line. In the frame piece 113b, in the vicinity of each bridge portion 117, a long hole-like groove 119 penetrating the front and back is provided so that the movable beam portion 115 is flexible even at a portion corresponding to the bridge portion 117.

  On the other hand, on one surface facing the opening window 111 in the fixed beam portion 114 and the movable beam portion 115, a holding groove 114 a as a holding portion that engages with the mounting claws 3 a that protrude in pairs on both side surfaces of the body 1. , 115a are provided at equal pitches for each three pairs (see FIGS. 9B and 9C). Therefore, when the mounting claws 3a provided on the container 1 are engaged with the holding grooves 114a and 115a, the container 1 is attached to the plate frame 110 with the front surface of the container 1 exposed from the opening window 111. can do. Further, the base of the fixed beam portion 114 and the movable beam portion 115 is in contact with the front surface of the shoulder portion 5 protruding from both side surfaces of the vessel body 1 so that the vessel body 1 does not fall forward from the plate frame 110. Portions 114d and 115d are formed. That is, the front surface of the shoulder portion 5 abuts against the abutting portions 114d and 115d, and the rear surface of the attachment claw 3a is engaged with the holding grooves 114a and 115a, so that the body 1 is attached to the plate frame 110.

  Here, the attachment claws 3a of the container 1 are introduced into the holding grooves 114a and 115a from the rear surface side of the plate frame 110 at the respective front end portions of the surface facing the opening window 111 of the fixed beam portion 114 and the movable beam portion 115. In order to guide each attachment claw 3a to the holding grooves 114a and 115a, guide portions 114b and 115b having inclined surfaces that are inclined so as to increase the distance from each other toward the tip end side are provided. That is, as shown in FIGS. 10A to 10C, in order to attach the container 1 to the plate frame 110, the attachment claws 3 a protruding from one side of the container 1 are provided in the holding groove 114 a of the fixed beam portion 114. When the container body 1 is pushed forward with respect to the plate frame 110 with the front end of the container body 1 substantially aligned with the opening window 111, the mounting claws 3a protruding from the other side surface of the container body 1 are While the movable beam portion 115 is bent, it is driven into the holding groove 115a by the inclined surface provided on the attachment claw 3a and the guide portion 115b, and the attachment claw 3a can be easily engaged with the holding groove 115a.

  On the other hand, at the base of the fixed beam portion 114, an instrument removal hole 114c that penetrates the plate frame 110 from the front and back is provided between each pair of adjacent holding grooves 114a, and the body 1 is attached to the plate frame 110. In this state, when a tip of a screwdriver or a tool dedicated for removal is inserted into the tool removal hole 114c and the body 1 is pushed toward the movable beam 115 by the tip of the tool, the movable beam is moved with a slight force by the lever principle. The portion 115 can be bent, and the body 1 can be detached from the plate frame 110 by releasing the engagement state between the holding groove 114 a on the fixed beam portion 114 side and the mounting claw 3 a of the body 1. ing.

  As described above, the plate frame 110 has three pairs of holding grooves 114a and 115a in the fixed beam portion 114 and the movable beam portion 115, respectively, and the body 1 is formed with a pair of mounting claws 3a on each side surface. Therefore, it is possible to attach up to three of the above-mentioned container 1 to the plate frame 110. In other words, the plate frame 110 is for three pieces, and the container 1 whose attachment dimensions are set so that a maximum of three plate frames 110 can be attached to the three plate frames 110 is referred to as one module-sized container body 1. I will decide. In this way, by defining the relative mounting dimensions of the container 1 and the plate frame 110, it is possible to attach an arbitrary number of containers 1 in the range of 1 to 3 to the plate frame 110. Become. The pitch of the holding grooves 114a and 115a provided in the fixed beam portion 114 and the movable beam portion 115 is equal to the pitch of the mounting claws 3a projecting from the side surface of the one-dimensional module body 1, and as described above. Since the holding grooves 114a and 115a are equally spaced, if the module 1 has one module size, the plate is formed by using any two holding grooves 114a and 115a adjacent to the fixed beam portion 114 and the movable beam portion 115. It can be attached to the frame 110. FIG. 1B shows a state in which the container 1 is attached to the plate frame 110.

  Incidentally, a recess 131 is formed in the front surface of the intermediate portion of each horizontal piece 112 of the plate frame 110. Each recess 131 has a box hole 132 through which a box screw for attaching the plate frame 110 to an embedding box (not shown) is inserted, and a screw for directly attaching the plate frame 110 to a construction surface such as a wall surface. And a scissor fitting locking hole 134 for engaging a scissor fitting (not shown) used when attaching to a wall panel or the like forming the construction surface.

  Further, at the four corners of the plate frame 110, decorative plate locking holes 135 for locking the locking protrusions 123 protruding from the rear surface of the decorative plate 120 are provided. The decorative plate 120 can be detachably attached so as to cover the front surface of the plate frame 110 by inserting and locking.

  The decorative plate 120 is formed using an insulating synthetic resin, and has a rectangular main portion 121 that covers the front surface of the plate frame 110, and the entire periphery from the periphery of the main portion 121. Thus, it is formed in a substantially box shape in which the side wall 122 protruding rearward is integrally formed.
