In the figure, reference numeral 1 denotes a connector of this embodiment, which is one of a pair of connectors as a connector assembly. The connector 1 is preferably a cable connector, and is used in a state where the connector 1 is connected to one end of a cable 91 and is fitted to a mating connector 101 (the pair of connector components as described below) The other of the connectors). The mating connector 101 is installed in devices such as a personal computer, a smartphone, a tablet terminal, a car navigation device, a car audio device, a car sensor, a car camera, a car lighting device, and a vehicle control device A connector on the electrical equipment, electronic equipment, etc., but can be installed on any type of equipment. For convenience of illustration, only the portion near the end of the cable 91 is drawn, and the other portions are omitted.

In addition, the cable 91 may be any type of cable, and may be a coaxial cable, a twisted pair cable, etc., but as shown in FIG. 2, the cable 91 will have a double axis with two parallel wires 93 Cable. The cable 91 includes: a first wire 93a in which a conductive first core wire 94a is covered with an insulated inner covering element 95; and a second wire 93b in which a conductive second core wire 94b is covered with an insulation The inner cover element 95, and the first wire 93a and the second wire 93b are arranged in parallel It is integrally covered with an insulating outer covering element 92. As shown in FIG. 2, it is assumed that a part of the first core wire 94 a and the second core wire 94 b within a predetermined length from the end is exposed in a state where the inner covering element 95 is removed. In addition, when the first core wire 94 a and the second core wire 94 b are collectively described, they will be collectively referred to as the core wire 94, and when the first conductive wire 93 a and the second conductive wire 93 b are collectively described, they will be collectively referred to as the conductive wire 93.

Here, the cable 91 and the connector 1 may be used to provide power or may be used to transmit a signal. In addition, the connector 1 will be described as a connector having a small diameter (for example, an outer diameter of about 3.0 mm (the outer diameter of a rear sleeve 12)).

In this embodiment, expressions such as up, down, left, right, front, and back that are used to explain the operation and configuration of the components of the connector 1 and the mating connector 101 are not absolute but relative, And although these indications are appropriate when the components of the connector 1 and the mating connector 101 are in the orientation shown in the figure, when these orientations change, these orientation indications should be variably interpreted in response to these changes.

The connector 1 includes: a front sleeve 11, which is integrally made of an insulating material such as a synthetic resin; and a housing 61, which serves as an outer conductor portion, which is formed by punching and pressing a conductive metal plate , An element formed by processing such as bending, etc., and housed in the front sleeve 11; an intermediate insulator 21, which is an element integrally formed of an insulating material such as synthetic resin, and housed in the housing 61; a terminal 51, as a The central conductor portion is an element integrally formed by performing processing such as punching, pressing, bending, etc. on the conductive metal plate and is housed in the intermediate insulator 21; a cap body 22, as a cover element, is formed by such as The synthetic resin is preferably an element integrally formed with a heat-resistant insulating material, and is provided on the rear side of the housing 61 and the terminal 51; a sealing element 31, which is made of materials such as synthetic resin An elastic body integrally formed by a grease and sealing the rear side of the housing 61, the terminal 51 and the cap 22 in a watertight manner; and a rear sleeve 12 which is an integrally formed element through an insulating material such as synthetic resin and It is provided on the rear side of the front sleeve 11.

The front sleeve 11, the cap 22, the sealing element 31, and the rear sleeve 12 are all integrated with other elements through overmolding (insert molding), and although shown separately from other elements, they are not separate There is, but it should be noted that the front sleeve 11, the cap 22, the sealing element 31, and the rear sleeve 12 are all shown in a separate manner in FIG.

As shown in FIGS. 5A to 5D, the housing 61 includes: a body portion 63 as a cylindrical outer body portion; and a tail portion 62 as an outer tail portion rearward from the rear end 63r of the body portion 63 (X axis negative Direction). The body portion 63 is a hollow portion made by rolling a flat metal plate into a cylindrical shape, and includes a seam 63c extending in the front-rear direction (X-axis direction). A cylindrical inner cavity 61a is formed inside the body portion 63, and the intermediate insulator 21 and the terminal 51 are accommodated in the inner cavity 61a.

In addition, the body portion 63 is formed such that a slit 63a extending in the circumferential direction intersects the slit 63c. The slit 63a is a portion where the insulating material constituting the front sleeve 11 enters and is formed to penetrate the metal plate constituting the body portion 63 in the plate thickness direction, but does not exist over the entire circumference of the body portion 63. The intermediate insulator 21 and the terminal 51 are accommodated in the inner cavity 61a through a small protrusion 21d provided on the outer side of the intermediate insulator 21 in a state of being lightly pressed into the rear of the slit 63a. That is, the small protrusion 21d is located behind the slit 63a as a light press-fitting portion. A plurality of locking protrusions 64 protruding inward in the radial direction are formed on the body portion 63 within a range between a front end 63f and the slit 63a. The locking protrusion 64 is fitted into the connector 1 The mating connector 101 included in the mating connector 101 is engaged with a mating housing 161 described later.

When the engaging housing 161 enters the inner cavity 61a from the front end 63f and engages with the locking protrusion 64 protruding radially inward, the locking protrusion 64 is pushed radially outward by the engaging housing 161, so the front end 63f of the body portion 63 and the slit The range between 63a is deformed and the diameter is enlarged. However, due to the existence of the slit 63a, this deformation is not transmitted to the rear of the slit 63a. Therefore, even if the fixing strength of the intermediate insulator 21 to the housing 61 cannot be increased due to miniaturization, the intermediate insulator 21 accommodated in the internal cavity 61 a and located behind the slit 63 a will not be separated from the main body 63.

In addition, the rear end 63r of the body portion 63 is provided with a notch portion 65 recessed forward. A positioning protrusion 21c of the intermediate insulator 21 enters the notch 65 to engage with the notch 65. In addition, an opening 63b penetrating the metal plate constituting the body portion 63 in the plate thickness direction is formed near the rear end 63r of the body portion 63. A part of the insulating material forming the cap body 22 enters the opening 63b formed through one side wall of the body portion 63.

A first connecting plate 62a and a second connecting plate 62b that are orthogonal to each other when viewed from a longitudinal direction (X-axis direction, that is, the front-rear direction) of the connector 1 are disposed near the rear end of the tail portion 62. The second connection plate 62b is formed by being bent at a right angle with respect to the first connection plate 62a. As shown in FIG. 4C, when viewed in the front-rear direction, the end of the second wire 93b of the cable 91 with the inner covering element 95 removed is exposed to the two core wires 94b that are orthogonal to each other on the circumferential surface, respectively. The first connection plate 62a and the second connection plate 62b are close to each other, and are connected to the first connection plate 62a and the second connection plate 62b through connection means such as welding. Therefore, even if the range where the second core wire 94b overlaps the tail portion 62 is short in the front-rear direction, because the second core wire 94b is connected to the first connection plate 62a and the second connection plate at two places on the circumferential surface of the second core wire 94b Since the connecting plate 62b is connected, the second core wire 94b and the tail portion 62 are reliably connected to each other and are electrically connected to each other.

The front sleeve 11 is integrally attached to the outside of the housing 61 through overmolding. As described above, because a part of the insulating material forming the front sleeve 11 enters the slit 63a of the housing 61, the front sleeve 11 is reliably attached to the housing 61. The front sleeve 11 is a substantially cylindrical element, and has a cylindrical inner cavity 11a penetrating in the axial direction (that is, the front-rear direction), and the housing 61 is located in the main body 63 in front of the notch 65. Partially accommodated in the internal cavity 11a. In addition, as shown in FIGS. 4A and 4B, the front sleeve 11 is in a state where the front sleeve 11 extends forward from the front end 63f of the body portion 63 of the housing 61, and the housing 61 is not present in the front sleeve in the internal cavity 11a The barrel 11 extends backward from a front end 11f of a housing within a predetermined length. In addition, a central axis of the inner cavity 11a is coaxial with the central axis of the inner cavity 61a of the housing 61, and an inner diameter of the inner cavity 11a is substantially the same as an outer diameter of the housing 61.

As shown in FIGS. 6A to 6D, the intermediate insulator 21 is a substantially cylindrical element and has a cylindrical inner cavity 21a penetrating in the axial direction (that is, the front-rear direction). A portion of the inner cavity 21a that is in contact with the front end 21f is provided with a tapered portion 21a1 whose inner diameter increases as it extends forward (X-axis positive direction). In addition, a corner hole portion 21a3 having a rectangular cross section is provided in a portion of the internal cavity 21a that is in contact with a rear end 21r. In addition, a portion of the inner cavity 21a between the tapered portion 21a1 and the corner hole portion 21a3 is a round hole portion 21a2 having a circular cross section, and the round hole portion 21a2 has a smaller inner diameter than the corner hole portion 21a3 One inside diameter. The terminal 51 is accommodated in the internal cavity 21a, the body portion 53 of the terminal 51 is accommodated in the corner hole portion 21a3, and a contact arm portion 54 of the terminal 51 is accommodated in the round hole portion 21a2. The tapered portion 21a1 serves as a guide for smoothly inserting the end of a mating terminal 151 described later included in the mating connector 101 of the mating connector 1 in the absence of the terminal 51.

In addition, a recess 21b is formed in the intermediate insulator 21 within a predetermined length in front of the rear end 21r. The concave portion 21 b is a portion where a part of the insulating material forming the cap body 22 enters, and is formed to be further recessed with respect to the outer peripheral surface of the intermediate insulator 21, but does not exist on the entire circumference of the intermediate insulator 21. In addition, a part of the rear end 21r is provided with a positioning protrusion 21c protruding rearward and radially outward. The positioning protrusion 21c protrudes radially outward from the outer circumferential surface of the intermediate insulator 21 and enters the notch 65 of the housing 61 to be engaged with the notch 65.

The intermediate insulator 21 is pressed into the inner cavity 61a of the housing 61 from the rear. At this time, the positioning protrusion 21c enters the notch 65 of the housing 61 from the rear to engage with the notch 65, and the positioning of the intermediate insulator 21 relative to the housing 61 in the front-rear direction and the circumferential direction is completed.

As shown in FIGS. 7A to 7C, the terminal 51 includes: a body portion 53 as a central body having a rectangular cylindrical shape with a rectangular cross section; a pair of contact arm portions 54 extending forward from the body portion 53; and a tail portion 52 , As a central tail, extending rearward from the main body 53. The body portion 53 is a portion formed by bending a flat metal plate into a rectangular tube shape, and one of the side walls of the rectangular tube is provided with an engaging protrusion 53a protruding outward. In addition, the base end of the contact arm portion 54 is integrally connected to the front ends of the pair of side walls of the corner tube. The contact arm 54 serves as a cantilevered leaf spring. The interval between the pair of contact arm portions 54 facing each other becomes narrower as it extends forward, and the interval between the pair of contact arm portions 54 at the end (ie, the free end) is preferably set smaller than that of the mating terminal 151 An outer diameter of the contact portion 154. When the connector 1 and the mating connector 101 are fitted with each other, since the mating terminal 151 enters between the pair of contact arm portions 54 facing each other to widen the interval between the pair of contact arm portions 54, both serve as cantilevers A pair of contact arm portions 54 of the flat leaf spring hold the mating terminal 151 from both sides thereof, thereby contacting the arm portion 54 and the mating terminal 151 The contact between them is reliably maintained and conducted.

The tail portion 52 has a connecting portion 52c integrally connected to the body portion 53. The connecting portion 52c is an element for connecting the rear end of the body portion 53 and the front end of the tail portion 52 and extends in a direction orthogonal to the front-rear direction (Y-axis direction in the example shown in the figure), and It serves as a cover element that closes the rear end of the main body portion 53 in the shape of an angle tube. In the example shown in the figure, the connecting portion 52c is bent at a substantially right angle from the rear end of the side wall on which the engaging protrusion 53a is formed on the angled cylindrical body portion 53, and is directed in the direction of the side wall facing the side wall (Y The axis extends in the negative direction), passes over the side walls facing each other, is bent at a substantially right angle, and then is integrally connected to the front end of the tail 52 extending in the front-rear direction. In this way, because the rear end of the angular tube-shaped body portion 53 is blocked by the connecting portion 52c, the insulating material forming the cap 22 or the elastic body forming the sealing element 31 is reliably prevented from entering the angular tube from the rear end and It enters between the pair of contact arms 54.

In addition, the first connection plate 52 a and the second connection plate 52 b that are orthogonal to each other when viewed from a longitudinal direction of the connector 1 (X-axis direction, that is, the front-rear direction) are provided near the rear end of the tail 52. The second connecting plate 52b is formed by being bent at a right angle with respect to the first connecting plate 52a. As shown in FIG. 4C, when viewed in the front-rear direction, the end of the first lead wire 93 a of the cable 91 with the inner cover element 95 removed removes the first core wire 94 a at two portions orthogonal to each other on the circumferential surface Or close to the first connection plate 52a and the second connection plate 52b, and connected to the first connection plate 52a and the second connection plate 52b through connection means such as welding. Therefore, even if the range where the first core wire 94a overlaps the tail portion 52 is short in the front-rear direction, because the first core wire 94a is connected to the first connection plate 52a and the second connection plate 52b at two places on the circumferential surface of the first core wire 94a, Therefore, the first core wire 94a and the tail 52 are reliably connected to each other and reliably conduct to each other.

The terminal 51 is pressed into the inner cavity 21a of the intermediate insulator 21 from the rear. Subsequently, the angular cylindrical body portion 53 enters the corner hole portion 21a3 formed in the portion of the inner cavity 21a that contacts the rear end 21r, and the pair of contact arm portions 54 enters the front of the corner hole portion 21a3 Inside the round hole portion 21a2. At this time, the inner diameter of the round hole portion 21a2 is smaller than the outer diameter of the body portion 53, and the portion of the coupling portion 52c near the front end of the tail portion 52 abuts a rear surface of the positioning protrusion 21c, so that the body portion 53 does not enter the circle In the case of the hole portion 21a2, the positioning of the terminal 51 with respect to the intermediate insulator 21 is completed in the front-rear direction. In addition, since the angular cylindrical body portion 53 is accommodated in the angular hole portion 21a3, the positioning of the terminal 51 with respect to the intermediate insulator 21 in the circumferential direction is completed. Since the engaging protrusion 53a of the body portion 53 bites into the inner wall of the corner hole portion 21a3, the terminal 51 does not displace relative to the intermediate insulator 21 in the front-rear direction. In addition, as shown in FIGS. 4A and 4B, the contact arm portion 54 stops within the circular hole portion 21a2 and does not enter the tapered portion 21a1.

In addition, in a state where the terminal 51 is pressed into the internal cavity 21 a of the intermediate insulator 21 (which has been pressed into the internal cavity 61 a of the housing 61 ), as shown in FIG. 4A, the tail 52 of the terminal 51 faces the tail 62 of the housing 61. Extend backwards. Specifically, the tail portion 52 of the terminal 51 is substantially flush with the cylindrical wall of the cylindrical body portion 63 of the housing 61, is located on the opposite side of the tail portion 62 of the housing 61 in the circumferential direction, and extends rearward. That is, the tail portion 52 of the terminal 51 and the tail portion 62 of the housing 61 form a part of a cylindrical wall surface having substantially the same diameter as the cylindrical wall surface of the body portion 63 of the housing 61. In addition, in the front-rear direction, the position of the rear end of the tail portion 52 of the terminal 51 is the same as the position of the rear end of the tail portion 62 of the housing 61, and the positions of the first connection plate 52a and the second connection plate 52b of the terminal 51 are The positions of the one connecting plate 62a and the second connecting plate 62b are also the same. As shown in FIG. 4C, the first connection plate 52a of the terminal 51 and the first connection plate 62a of the housing 61 face each other, and the second connection plate 52b of the terminal 51 and the second connection plate 62b of the housing 61 are large Flush.

In this way, after the intermediate insulator 21 is pressed into the inner cavity 61a of the housing 61 and the terminal 51 is pressed into the inner cavity 21a of the intermediate insulator 21, the cap 22 as shown in FIGS. 9A to 10C is integrally formed in the middle by overmolding The rear side of the insulator 21 and the terminal 51. For the sake of convenience, in FIGS. 9A to 10C, the cap body 22 is shown separately, but the cap body 22 undergoes overmolding (insert molding), in which the insulator 21, the terminal 51, and the housing 61 are installed in the molding In the state in the mold, a dielectric material such as a synthetic resin is filled in the mold, and thus becomes an element integrally formed with the intermediate insulator 21, the terminal 51, and the housing 61, so that the cap body 22 is not as shown in FIG. 9A to 10C actually exist in a single body of a shape shown in FIG.

As a result, the insulating material forming the cap 22 enters the rear end 63r of the body portion 63 of the housing 61 in which the intermediate insulator 21 and the terminal 51 are housed and enters the housing 61 near the rear end 63r on the outer circumferential surface of the body portion 63 , The gap between the intermediate insulator 21 and the terminal 51 to close the rear end 63r of the body portion 63 of the housing 61 and the gap between the housing 61, the intermediate insulator 21 and the terminal 51. In addition, the insulating material forming the cap 22 passes through the recess 21b of the intermediate insulator 21, enters the opening 63b formed in the body 63 of the housing 61, and fills the recess 21b and the opening 63b to form the cap 22, so that the cap 22 is reliably Attached to the housing 61 and the intermediate insulator 21. In addition, since the rear end blocked by the connecting portion 52c is blocked from the rear by the cap body 22, the body portion 53 of the terminal 51 housed in the corner hole portion 21a3 of the internal cavity 21a of the intermediate insulator 21 is not blocked from the corner The hole 21a3 is pulled out.

Specifically, the cylindrical portion 22c of the cap body 22 enters the concave portion 21b of the intermediate insulator 21 located in the inner cavity 61a of the body portion 63 from the rear end 63r side of the body portion 63 of the housing 61, opposite the cylindrical portion 22c A radially outer portion 22h enters between the notch 65 of the housing 61 and the positioning protrusion 21c of the intermediate insulator 21 and covers the positioning protrusion 21c, and protrudes radially outward from the outer surface of the cylindrical portion 22c 22b enters the opening 63b of the housing 61. In addition, a portion near the rear end of the intermediate insulator 21 enters a front cavity 22d formed in the cylindrical portion 22c, and a portion near the rear end of the body portion 53 of the terminal 51 enters a rear cavity behind the front cavity 22d The body 22e, the portion near the front end of the tail portion 62 of the housing 61 enters a notch 22g on the outer periphery, and the positioning protrusion 21c enters an outer cavity 22i in the outer portion 22h.

The recess 21b of the intermediate insulator 21 does not extend over the entire circumference of the intermediate insulator 21, and as shown in FIGS. 6A to 6D, a rear convex portion 21e forms a part of the circumference of the intermediate insulator 21. Therefore, the cylindrical portion 22c of the cap body 22 is provided with a concave portion 22m corresponding to the rear convex portion 21e, as shown in FIGS. 10A to 10C, and is provided with a body portion 63 that enters the outer peripheral surface of the intermediate insulator 21 and the housing 61 The thin-walled portion 22k in the small gap between the inner peripheral surfaces of the two is as shown in FIGS. 9A to 10C. Although the thin-walled portion 22k may not be formed due to the change in the gap, even if the thin-walled portion 22k is not formed, the waterproof performance is not affected by the cap body 22.

As described above, the cap body 22 is formed by overmolding, and thus the cap body 22, the intermediate insulator 21, the housing 61, and the terminal 51 can be reliably integrated even if each element becomes smaller for miniaturization. 11A and 11B show a part of the assembly in a state where the front sleeve 11 is formed by overmolding. In addition, when the cap body 22 is formed by overmolding, a gate formed on the wall surface of the forming mold (mold) (not shown) is located immediately in front of the rear surface of the cap body 22, as shown in FIG. 11B , And the insulating material forming the cap body 22 is filled in the forming mold through the gate as indicated by arrow 43 and enters Components to integrate these components. The gate can be only one point, but it can be multiple points. For example, the gate 43 and the gate 43a can be disposed to face each other on both sides of the cap body 22 in the Z-axis direction. As a result, when the molding die is filled with an insulating material, the pressure of the insulating material acting on the elements in the molding die is more likely to be uniform, and the occurrence of short molding due to deviation of these elements is suppressed. It should be noted that a gate mark 22j remains on the surface of the cap body 22 after forming.

As shown in FIGS. 8A and 8B, the outer peripheral surface of the cap body 22 becomes a circumferential surface that is substantially flush with the outer peripheral surface of the cylindrical body portion 63 of the housing 61. In addition, an umbrella-shaped or mushroom-shaped anchor portion 22a protruding backward is formed on the rear surface of the cap body 22, and a constricted portion 22f is formed between the rear surface of the cap body 22 and the anchor portion 22a. The tail portion 62 of the housing 61 is exposed by protruding backward from a boundary portion between the rear surface and the circumferential surface of the cap body 22, so that at least the first connection plate 62a and the second connection plate 62b are located behind the anchor portion 22a. Similarly, the tail portion 52 of the terminal 51 is exposed by protruding backward from the boundary portion between the rear surface and the circumferential surface of the cap 22, so that at least the first connection plate 52a and the second connection plate 52b are located behind the anchor portion 22a.

The core 94 of the cable 91 is connected to the tail 52 of the terminal 51 and the tail 62 of the housing 61. Here, the first connection plate 52a and the second connection plate 52b of the tail portion 52 of the terminal 51 and the first connection plate 62a and the second connection plate 62b of the tail portion 62 of the housing 61 are provided at the anchor portion of the cap body 22 in the front-rear direction At the same position behind 22a, the first connection plate 52a of the terminal 51 and the first connection portion 62a of the housing 61 face each other, while the second connection plate 52b of the terminal 51 and the second connection plate 62b of the housing 61 are substantially flush with each other .

Therefore, the inner cover element 95 of the cable 91 is removed and the parallel arranged first core wire 94a and the second core wire 94b are mounted on the second connection plate 52b of the parallel arranged terminal 51 and the first On the two connection plates 62b, and as a result, as shown in FIGS. 8A and 8B, the first core wire 94a abuts or approaches the first connection plate 52a and the second connection plate 52b of the tail 52 of the terminal 51 and the second core wire 94b abuts Or the first connection plate 62a and the second connection plate 62b close to the tail portion 62 of the housing 61. By performing connection such as welding, the two parts of the first core wire 94a on the circumferential surface are connected to the first and second connection plates 52a and 52b, and the two parts of the second core wire 94b on the circumferential surface are also connected to The first connection plate 62a and the second connection plate 62b. In this way, since the first core wire 94a and the second core wire 94b of the cable 91 can be connected to the tail portion 52 of the terminal 51 and the tail portion 62 of the housing 61 through a relatively simple operation (for example, a robot, etc.), the connector 1 The assembly work can be simplified and rationalized, and production costs can be reduced. In addition, since the two portions of the first core wire 94a on the circumferential surface are connected to the first connection plate 52a and the second connection plate 52b, the two portions of the second core wire 94b on the circumferential surface are connected to the first connection plate 62a and the first Two connecting plates 62b, even if the overlapping length of the first core wire 94a and the second core wire 94b with the tail 52 and the tail 62 is short in the front-rear direction, the sum of the lengths of the first core wire 94a connected to the tail 52 and the second core wire 94b connected to the tail The total length of 62 becomes longer, making the connection reliable.

In this way, after the core wire 94 of the cable 91 is connected to the tail 52 of the terminal 51 and the tail 62 of the housing 61, the sealing element 31 is integrally attached to the rear side of the molded terminal 51, the housing 61, and the cap 22 by overmolding . The elastic body forming the sealing element 31 (which is a material having higher flexibility than the materials of the front sleeve 11, the cap body 22, and the rear sleeve 12) enters the housing 61, the intermediate insulator 21, the terminal 51, and the cap There is a gap between the bodies 22, thereby sealing the gap in a watertight manner. In addition, the elastic body covers the periphery of the tail 52 of the terminal 51 and the tail 62 of the housing 61 and the core 94 of the cable 91 connected to them without a gap, and seals the gap in a water-tight manner. Preferably, as As shown in FIGS. 4A to 4C, the sealing element 31 is formed such that the front portion of the sealing element 31 overlaps the rear end on the outer peripheral surface of the front sleeve 11 and a portion near the rear end in the front-rear direction, and the rear portion of the sealing element 31 covers Around each element in a range up to at least the anchor portion 22a of the cap 22. In addition, the sealing element 31 may be formed so as to cover the periphery of each element in a range up to a portion near the inner end of the lead wire 93 that covers the front end of the outer circumferential surface of the element 95 without a gap.

Therefore, the anchor portion 22a of the cap body 22 is buried in the sealing element 31 and the sealing element 31 enters around the constriction 22f, so that the cap body 22 and the sealing element 31 are reliably combined with each other. In addition, since the elastic body forming the sealing element 31 has high flexibility and covers the tail portion 52 of the terminal 51 and the tail portion 62 of the housing 61 and the core 94 of the cable 91 connected thereto without gaps, the tail portion 52 of the terminal 51 The tail portion 62 of the casing 61 and the core wire 94 can be reliably waterproofed.

After the sealing element 31 is integrally formed by overmolding, the sealing element 31 and the housing 61 are closely adhered to each other through reheating, so that the waterproof performance can be further improved.

Subsequently, the rear sleeve 12 is integrally attached to the rear of the front sleeve 11 by overmolding to cover the circumference of the sealing element 31 and the wire 93 of the cable 91. The rear sleeve 12 is an element for forming the outermost layer of the connector 1 together with the front sleeve 11, and preferably, as shown in FIGS. 4A to 4C, the rear sleeve 12 is formed to approach the front in the front-rear direction The portion from the rear end on the outer peripheral surface of the sleeve 11 to the portion near the outer end of the cable 91 covering the front end on the outer peripheral surface of the element 92 covers the periphery of each element without a gap.

It should be noted that the rear sleeve 12 may have a recess 12b that exists on the entire circumference of the outer surface. The recess 12b is used to fit or unfit the connector 1 and the mating connector 101 (i.e. Connector 1) hook an appliance (jig, not shown). In addition, when the rear sleeve 12 is formed by overmolding, the gate formed on the wall surface of the molding die (mold) (not shown) is located immediately behind the recess 12b as shown in FIG. 4A and forms the rear The insulating material of the sleeve 12 is filled into the forming mold through the gate, as indicated by the arrow 41.

Preferably, the gates face each other on both sides of the rear sleeve 12 in the Y-axis direction. As a result, when the forming mold is filled with an insulating material as indicated by arrow 41, the pressure of the insulating material acting on the element in the forming mold is more likely to be uniform, and the dissatisfaction of the workpiece due to the deviation of the element is suppressed. The position of the gate is preferably close to the outer covering element 92 to improve the fusion between the insulating material forming the rear sleeve 12 and the outer covering element 92 of the cable 91, but the outer covering element 92 exists directly under the gate This is undesirable because the outer covering element 92 is deformed by an injection pressure of the insulating material. In addition, when the rear sleeve 12 has the recess 12b, the gate is preferably positioned closer to the outer covering element 92 than the recess 12b. If the position of the gate is closer to the front sleeve 11 than the thin recess 12b, the pressure of filling the mold for molding with an insulating material is necessarily increased, and the cable 91 may be deformed. Taking these facts into consideration, it is preferable that the gate is in the position shown in FIG. 4A. It should be noted that a gate mark 12c remains on the surface of the formed rear sleeve 12.

In addition, the insulating material filled in the forming mold overflows and flows out from the forming mold as indicated by the arrow 42. Preferably, the outflow of the insulating material due to the overflow also occurs at positions facing each other on both sides of the rear sleeve 12 in the Y-axis direction. The insulating material overflows, so that the fusion between the insulating material forming the rear sleeve 12 and the outer covering element 92 of the cable 91 becomes high, thereby improving the waterproof performance. Preferably, the position where the insulating material flows out is close to the rear end 12r of the rear sleeve 12 to improve the insulating material and the outside The fusion between the cover elements 92. It should be noted that an overflow mark 12d remains on the surface of the formed rear sleeve 12.

Next, the configuration of the mating connector 101 will be explained.

The mating connector 101 includes: a mating housing 111, which is integrally formed of an insulating material such as a synthetic resin; and a mating housing 161, as a mating outer conductor portion, by performing such operations as punching, pressing, and bending on a conductive metal plate An element formed by processing, etc., and housed in the mating housing 111; the mating terminal 151, as the mating center conductor, is punched, pressed, An element integrally formed by bending or the like and housed in the mating housing 111; the mating sealing element 131, which is an element integrally formed by an elastomer such as a synthetic resin rubber, is hermetically sealed in a watertight manner The rear side of the housing 161 and the mating terminal 151; and the first outer sealing element 141 and the second outer sealing element 142 of the O-ring type, which are integrally formed through an elastomer such as synthetic resin and attached to the mating housing 111 outer peripheral surface.

The mating housing 111 and the mating sealing element 131 are integrated with other components through overmolding.

As shown in FIGS. 17A and 17B, the mating housing 161 includes: a flat body portion 163 extending in the front-rear direction (X-axis direction); and a flat tail portion 162 rearward from the rear end of the body portion 163 (X The axis extends in the positive direction); and a cylindrical contact portion 164 connected to the front end of the body portion 163. The tail portion 162 is a flat plate-shaped element wider than the body portion 163, and is connected to a connector, a circuit board, and a wire such as a wire included in a device (not shown) mounted with the mating connector 101. In addition, the inclined portions 162a are formed on both sides in the width direction, so that the front end of the tail portion 162 smoothly transitions to the body portion 163 having a narrow width.

In addition, the contact portion 164 is a portion made by rolling a flat metal plate into a cylindrical shape, and includes a seam 164c extending in the front-rear direction (X-axis direction). The inside of the contact portion 164 is a cylindrical inner cavity 164a, and the contact portion 154 of the mating terminal 151 passes through the inner cavity 164a. In addition, the outer peripheral surface of the contact portion 164 is provided with a concave portion 164b extending over the entire circumference in the circumferential direction. The recess 164b is engaged with the locking protrusion 64 of the housing 61 included in the connector 1 of the mating connector 101. In addition, near the rear end of the contact portion 164, a contact portion 164 is formed through the thickness direction An opening 164d of the metal plate. A part of the insulating material forming the fitting housing 111 enters the opening 164d.

A curved portion 163a having a substantially crank-like side shape is formed on the way of the body portion 163. As shown in FIG. 17B, the portion of the body portion 163 other than the curved portion 163a and the tail portion 162 are offset axially (in the example shown in the figure, the negative direction of the Z axis) with respect to the central axis of the cylindrical contact portion 164, To extend straight in the front-rear direction. As shown in FIG. 13B, the body portion 153 of the mating terminal 151 is offset in a direction opposite to the body portion 163 and the tail portion 162 across the central axis (in the example shown in the figure, the positive direction of the Z axis), to Straight in the front-rear direction. The curved portion 163a is shifted more than the tail portion 162 from the body portion 163 except for the curved portion 163a. Therefore, because the interval between the curved portion 163a and the body portion 153 of the mating terminal 151 is large, when the mating housing 111 is molded by overmolding, the insulating material filled in the molding die (not shown) smoothly The flow passes through the gap between the curved portion 163a and the body portion 153 of the mating terminal 151 to uniformly fill the entire molding die.

As shown in FIGS. 13A and 13B, the gate formed on the wall surface of the forming mold (die) (not shown) is located between the curved portion 163a of the body portion 163 of the mating housing 161 and the body portion 153 of the mating terminal 151 And, the insulating material forming the mating case 111 is filled into the forming mold through the gate as indicated by arrow 44 and enters various parts to integrate these elements. The thickness of the body portion 163 of the mating housing 161 is thinner than that of the body portion 153 of the mating terminal 151, and a curved portion 163a is provided on the thinner side to allow the flow of the insulating material to escape. As a result, it is possible to prevent the fitting housing 161 and the fitting terminal 151 from being deformed due to the flow of the insulating material during the overmolding process.

As shown in FIGS. 16A and 16B, the mating terminal 151 includes: a flat body portion 153 extending in the front-rear direction (X-axis direction); a flat tail portion 152 rearward from the rear end of the body portion 153 (X-axis positive direction) extends; and a cylindrical contact portion 154 is connected to the front end of the body portion 153. The tail portion 152 is a flat plate-shaped element wider than the body portion 153, and is connected to a connector, a circuit board, and a lead wire such as a wire included in a device (not shown) mounted with the mating connector 101. Subsequently, the contact portion 154 enters between the contact arm portions 54 of the terminal 51 of the connector 1 of the mating connector 101 that are opposed to each other, and is held from both sides thereof. As a result, the contact between the contact portion 154 of the mating terminal 151 and the contact arm portion 54 of the terminal 51 is reliably maintained, and the contact portion 154 of the mating terminal 151 and the contact arm portion 54 of the terminal 51 are reliably conducted to each other. In addition, the inclined portions 152a are formed on both sides in the width direction, so that the front end of the tail portion 152 smoothly transitions to the body portion 153 having a narrow width.

In addition, a stepped portion 153a is provided near the front end of the body portion 153, and the stepped portion 153a has a substantially stepped side shape. As shown in FIG. 13B, the portion of the body portion 153 located in front of the stepped portion 153a (negative direction of the X axis) and the contact portion 154 substantially linearly extend in line with the central axis of the contact portion 164 of the cylindrical fitting housing 161, However, the portion of the body portion 153 located behind the stepped portion 153a (X-axis positive direction) and the tail portion 152 are offset in the front-rear direction offset downward from the center axis (in the example shown in the figure, the Z-axis positive direction) Straight. As described above, the body portion 153 and the tail portion 152 are offset in the opposite direction to the body portion 163 and the tail portion 162 of the mating housing 161 across the center axis so as not to contact the body portion 163 and the tail portion 162 of the mating housing 161.

In a state where the mating housing 161 and the mating terminal 151 are arranged to have a positional relationship as shown in FIGS. 13B and 14B, the mating sealing element 131 is integrally attached by overmolding to surround the body portion 163 of the mating housing 161 Around the connecting portion between the tail portion 162 and the connecting portion between the body portion 153 and the tail portion 152 of the mating terminal 151. Forming an elastic body (which It is a material that is higher in flexibility than the material of the mating housing 111) The gap between and around the mating housing 161 and the mating terminal 151 is sealed in a water-tight manner.

Subsequently, the fitting housing 111 is integrally attached by overmolding to cover the periphery of the fitting housing 161, the fitting terminal 151, and the fitting sealing member 131. As shown in FIGS. 13A to 15D, the fitting housing 111 covers the periphery of the fitting sealing element 131 and keeps the elastic body forming the fitting sealing element 131 defined therein. At this time, because the inclined portion 162a is formed at the connection portion between the body portion 163 and the tail portion 162 of the mating housing 161 and the inclined portion 152a is formed at the connection portion between the body portion 153 and the tail portion 152 of the mating terminal 151 to support the elastic body, so even When the mating housing 111 is overmolded, an elastomer with a high flexibility material is pushed by the flowing insulating material or the insulating material forming the mating housing 111 is pressed from the surroundings. The connection portion between the tail portions 162 and the periphery of the connection portion between the body portion 153 and the tail portion 152 in the mating terminal 151 can be kept surrounded without the elastic body flowing out.

It is not always necessary to form inclined portions 152a, 162a in the tail portion 152 of the mating terminal 151 and the tail portion 162 of the mating housing 161, and as shown in FIGS. 15C and 15D, if the mating sealing element 131 is arranged to be caught in front of the tail portions 152, 162 Nearby, even if the inclined portions 152a and 162a are omitted, the same action and effect can be obtained. That is, preferably, the mating sealing element 131 surrounds the connecting portion between the body portion 153 and the tail portion 152 of the mating terminal 151 and the connecting portion between the body portion 163 and the tail portion 162 of the mating housing 161.

In addition, as shown in FIGS. 12A to 15D, the mating housing 111 covers the entire body portion 153 of the mating terminal 151 and the entire contact portion 164 and body portion of the mating housing 161 in the front-rear direction 163, and has a range of a predetermined length from the end of the contact portion 154 of the mating terminal 151 protruding forward from a housing front end 111f (X-axis negative direction) to protrude, and has a tail 162 and mating from the mating housing 161 A range of a predetermined length of the rear end of the tail portion 152 of the terminal 151 is exposed backward from the rear end 111r of a case (positive direction of the X axis) to protrude. Preferably, a plate-shaped intervention portion 111b interposed between the tail portion 162 of the mating housing 161 and the tail portion 152 of the mating terminal 151 is formed behind the rear end 111r of the housing. In addition, the fitting housing 111 is formed so that at least a part of the cylindrical outer peripheral surface of the contact portion 164 of the fitting housing 161 is exposed at a portion near the front end 111 f of the housing. Since a part of the insulating material forming the fitting housing 111 enters the opening 164 d formed on the contact portion 164, the contact portion 164 is reliably attached to the fitting housing 111.

In addition, a flange portion 111a protruding outward in the radial direction is formed near the middle between the front end 111f and the rear end 111r of the housing on the outer circumferential surface of the mating housing 111 in the front-rear direction. The flange portion 111a is a portion for attaching to an outer wall of a box of a device (not shown) to which the mating connector 101 is installed, and the mating connector 101 of the mating connector 101 is located in front of the flange portion 111a The part is exposed to the outside of the case, and the part of the mating connector 101 that is located behind the flange portion 111a of the mating connector 101 is housed inside the case. In addition, a first groove portion 111c is formed on a portion in front of the flange portion 111a over the entire circumference of the outer circumferential surface of the fitting housing 111, and a second groove portion 111d is formed on the outer circumferential surface of the fitting housing 111 Is formed on the rear part of the flange portion 111a over the entire circumference. The first outer sealing element 141 is attached to the first groove portion 111c and the second outer sealing element 142 is attached to the second groove portion 111d. The first outer sealing element 141 and the second outer sealing element 142 protrude outward in the radial direction from the outer peripheral surface of the mating connector 101 before and after the flange portion 111a.

In addition, a third groove portion 111e is formed on the rear portion of the second groove portion 111d over the entire circumference of the outer peripheral surface of the fitting housing 111. When the fitting housing 111 is pressed into the hole formed in the outer wall of the box body, the third groove portion 111e is generated due to friction between the portion behind the third groove portion 111e of the fitting housing 111 and the hole In the case of debris, etc., a tank for containing debris, etc. Since the debris and the like are accommodated in the third groove portion 111e, the waterproof performance can be prevented from being reduced due to the debris and the like adhering to the second outer sealing member 142. When the fitting housing 111 is not fitted in the connector 1, water is prevented from entering the case through the fitting sealing element 131 and the second outer sealing element 142.

Next, the fitting state of the connector 1 and the mating connector 101 configured as described above will be explained.

18A and 18B are a two-face view showing a state where the connector and the mating connector according to the present embodiment are fitted with each other. In FIG. 18, FIG. 18A is a top view and FIG. 18B is a cross-sectional view taken along line M-M of FIG. 18A.

In this embodiment, the connector 1 and the mating connector 101 are brought closer to each other from a state where the front end 11f of the housing of the front sleeve 11 and the front end 111f of the mating housing 111 face each other and separate from each other, And the housing front end 111f of the mating housing 111 relatively enters the internal cavity 11a opened at the housing front end 11f of the front sleeve 11, so that the housing front end 111f of the mating housing 111 and the internal cavity 11a are fitted to each other, as shown in FIG. 18A and 18B.

When the connector 1 and the mating connector 101 are fitted to each other, the front portion of the flange portion 111a of the mating housing 111 enters the internal cavity 11a of the front sleeve 11 to be housed in the internal cavity 11a, the front portion The exposed contact portion 164 of the mating housing 161 enters the inner cavity 61a of the housing 61 to receive Accommodated in the inner cavity 61a, the flange portion 111a of the mating housing 111 approaches or abuts the front end 11f of the front sleeve 11, and the housing front 111f of the mating housing 111 approaches or abuts the front end 21f of the intermediate insulator 21 , And the contact portion 154 of the mating terminal 151 enters the internal cavity 21a opened at the front end 21f of the intermediate insulator 21 and enters between the terminals 51 of the pair of contact arm portions 54 housed in the internal cavity 21a and is removed from the two Side hold.

In addition, the vicinity of the front end 111f of the mating case 111 and the vicinity of the front end 21f of the intermediate insulator 21 are substantially the same in diameter, and are arranged in parallel in the insertion and removal direction (X-axis direction) of the connector 1 and the mating connector 101 . Similarly, the contact portion 164 of the mating case 161 is also arranged in parallel with the intermediate insulator 21 and the terminal 51 in the insertion and removal direction. In addition, the component of the mating connector 101 that enters the rear (the X-axis negative direction) from the slit 63a of the housing 61 is only the contact portion 154 of the mating terminal 151, and the mating housing 111 or the mating housing 161 does not further enter the rear of the slit 63a. In addition, even if the connector 1 and the mating connector 101 are twisted while being fitted to each other or the cable 91 is pulled diagonally, because the portion in front of the slit 63a (positive direction of the X axis) of the housing 61 can be smoothly displaced to cope with this Correspondence, so that even if the fitting between the connector 1 and the mating connector 101 is released, the connector 1 or the mating connector 101 will not be damaged. Therefore, the diameters of the connector 1 and the mating connector 101 can be reduced, and a connector assembly can be obtained that is not easily damaged while maintaining the plug-in performance (fitting feeling, insertion force, tension of pull-out force, etc.) and the connector 1 Contact with mating connector 101.

In addition, since the tapered portion 21a1 is formed in the inner cavity 21a of the intermediate insulator 21, the tip of the mating terminal 151 can smoothly enter the inner cavity 21a. In addition, since the interval between the contact arm portions 54 at the free end is smaller than the outer diameter of the mating terminal 151, if the mating terminal 151 enters Between the pair of contact arm portions 54, the interval between the pair of contact arm portions 54 facing each other is enlarged and generates an elastic reaction force to grip the mating terminal 151 from both sides. As a result, the contact between the contact arm portion 54 and the mating terminal 151 is reliably maintained and reliably conducted to each other. In addition, the plurality of locking protrusions 64 formed on the body portion 63 of the housing 61 are engaged with the concave portions 164 b formed on the contact portions 164 of the mating housing 161. As a result, the contact between the body portion 63 of the housing 61 and the contact portion 164 of the mating housing 161 is reliably maintained and reliably conducts to each other. In addition, the first outer sealing element 141 attached to the first groove portion 111 c of the fitting housing 111 is pressed against the inner circumferential surface of the inner cavity 11 a of the front sleeve 11. As a result, the gap between the outer circumferential surface of the mating case 111 and the inner circumferential surface of the inner cavity 11a of the front sleeve 11 is sealed in a watertight manner to prevent moisture from entering.

Even if moisture permeates through the portion sealed by the first outer sealing element 141, in the connector 1, the tail 52 of the terminal 51 and the tail 62 of the housing 61 and the core 94 of the cable 91 connected to them are affected The sealing member 31 covers, so that moisture is reliably prevented from entering the tail portion 52 of the terminal 51, the tail portion 62 of the housing 61, and the core wire 94. Likewise, in the mating connector 101, since the mating sealing member 131 covers the area between and around the mating housing 161 and the mating terminal 151, moisture is reliably prevented from entering the tail 152 of the mating terminal 151 and the tail 162 of the mating housing 161 .
