Moreover, the definition of the direction described above is not intended to limit the usage patterns of the connector 101 and the mating connector 102 of the present embodiment.

(2.1) Connector First, the connector 101 of this embodiment will be described in detail with reference to FIGS. 1 to 7. FIG. A connector 101 of this embodiment is a socket (female connector) and includes a housing 1 , a plurality of (here, six) contacts 2 , and a pair of holding metal fittings 3 .

The housing 1 is a flat rectangular parallelepiped elongated in the front-rear direction, and is a resin molded body made of an insulating resin material (for example, LCP (Liquid Crystal Polymer) resin). In this embodiment, the housing 1 is an insert-molded product having a pair of holding metal fittings 3 as inserts. Housing 1 has a bottom wall 12 and a peripheral wall 11 . The bottom wall 12 is in the shape of a plate elongated in the front-rear direction and constitutes the bottom of the housing 1 . The peripheral wall 11 protrudes upward from the peripheral edge of the bottom wall 12 and has a rectangular frame shape in plan view.

Specifically, the peripheral wall 11 is composed of a pair of first wall portions 121 and a pair of second wall portions 122 . The pair of first walls 121 are a pair of walls of the peripheral wall 11 along the front-rear direction. The pair of second wall portions 122 are a pair of wall portions of the peripheral wall 11 along the left-right direction. In other words, the pair of second walls 122 are walls that intersect (perpendicularly, for example) the front-rear direction. A portion surrounded by the pair of first wall portions 121, the pair of second wall portions 122, and the bottom wall 12 constitutes a recess 13 in which the housing 60 of the mating connector 102 is fitted. That is, the peripheral wall 11 surrounds the recess 13 . The mating connector 102 is connected to the connector 101 by fitting the housing 60 of the mating connector 102 into the recess 13 .

The housing 1 has a plurality of (here, six) slits 123 spaced apart in the front-rear direction. Each of the six slits 123 has a rectangular shape elongated in the horizontal direction in a plan view, and includes a pair of first through portions 15 vertically penetrating the pair of first wall portions 121 and vertically extending through the bottom wall 12 . and a second through portion 16 penetrating through. The six contacts 2 are held by the housing 1 by being pushed into the six slits 123 from below.

The housing 1 has a taper 124 on the upper half of the inner surface of the second wall portion 122 . The taper 124 is inclined so as to widen the opening area of the recess 13 from its lower end to its upper end. The taper 124 serves as a surface that guides the mating connector 102 into the recess 13 of the connector 101 when the mating connector 102 is fitted into the recess 13 . The lower half of the inner surface of the second wall portion 122 is, for example, perpendicular to the upper surface of the bottom wall 12 (that is, parallel to the outer surface of the second wall portion 122).

The contact 2 is a metal compact made of a metal material such as copper alloy. The contact 2 is plated with gold. Note that the contact 2 may not be plated with gold. As shown in FIGS. 3 and 4, the contact 2 has a pair of contact terminals 21, a connecting portion 23, and a pair of joint terminals 24, which are integrally constructed.

Each of the pair of contact terminals 21 has an inner piece 211, an outer piece 212, a connecting piece 213, an edge portion 214, and a projecting portion 215, which are integrally formed. Each of the pair of contact terminals 21 has an inverted U shape with the upper end as the apex when viewed from the front and back. The pair of contact terminals 21 are held by the pair of first wall portions 121 while being aligned in the left-right direction. That is, the pair of contact terminals 21 are held by the peripheral wall 11 while facing each other with the recess 13 interposed therebetween. In this embodiment, there is no obstacle (for example, part of the housing 1 and/or terminals) between the pair of contact terminals 21 (see FIG. 1). In other words, the pair of contact terminals 21 face each other inside the recess 13 without interposing an obstacle therebetween.

The inner piece 211 has, for example, a rectangular plate shape elongated in the vertical direction, and is exposed in the concave portion 13 (see FIG. 1). The inner piece 211 is arranged to contact a contact 70 of the mating connector 102, which will be described later, when the connector 101 is connected to the mating connector 102 (that is, the mating connector 102 is fitted in the recess 13 of the connector 101). .

The inner side surface of the inner piece 211 is integrally provided with a protrusion 215 (second hook portion) that protrudes in the thickness direction (horizontal direction) of the inner piece 211 . The inner side surface is the inner side surface in the direction (horizontal direction) in which each of the pair of contact terminals 21 faces each other. That is, each of the pair of contact terminals 21 has a protrusion 215 provided on the inner side surface facing each other. The projecting portion 215 is a portion that hooks with a hooking recess 77 (second mating hooking portion) of a contact 70B of the mating connector 102 when the connector 101 is connected to the mating connector 102 . Projection amount W1 of projection 215 is greater than depth W2 of hooking recess 77 . For example, the protrusion amount W1 is 0.02 m and the depth W2 is 0.015. Accordingly, when the connector 101 is connected to the mating connector 102 , the projection 215 contacts the bottom surface of the hook recess 77 . As a result, the pair of contact terminals 21 and the contact 70B are stably brought into electrical contact.

More specifically, when the connector 101 is connected to the mating connector 102, the protrusion 215 is vertically aligned with the stepped portion 77a of the hooking recess 77 and positioned above the stepped portion 77a (see FIG. 13B). ). Therefore, unless the mating connector 102 is pulled out from the connector 101 with a force greater than a predetermined amount, the stepped portion 77a of the contact 70B is caught by the protrusion 215 of the contact 2, thereby releasing the connection between the connector 101 and the mating connector 102. not. In other words, the projection 215 of the contact 2 and the hooking recess 77 of the contact 70B constitute a lock mechanism capable of releasing the connection state between the connector 101 and the mating connector 102 by applying a force greater than or equal to a predetermined amount.

The outer piece 212 has, for example, a rectangular plate shape elongated in the vertical direction, and faces the inner piece 211 . The outer piece 212 is located outside the inner piece 211 in the direction in which the pair of contact terminals 21 are arranged (horizontal direction). The outer piece 212 is not exposed in the concave portion 13 and is held by the peripheral wall 11 (first wall portion 121). A left surface (outer surface) of the left outer piece 212 is spaced apart from the left first wall portion 121 (see FIG. 7). Similarly, the right surface (outer surface) of the right outer piece 212 is spaced apart from the right first wall portion 121 . That is, the outer piece 212 has a surface opposite to the surface facing the inner piece 211 (outer surface) and is spaced apart from the peripheral wall 11 .

The connecting piece 213 connects the upper ends of the inner piece 211 and the outer piece 212 (the end opposite to the connecting portion 23). The connecting piece 213 has an inverted U shape with the upper end as the apex when viewed from the front and back.

The gill portion 214 is a portion held by the peripheral wall 11 . The gill portion 214 protrudes in the front-rear direction from each of the front-rear ends of the outer piece 212 .

The connecting portion 23 has, for example, a rectangular plate shape elongated in the left-right direction. The connecting portion 23 is sandwiched between the pair of contact terminals 21 so as to block the second penetrating portion 16 of the bottom wall 12 of the slit 123 . The left end of the connecting portion 23 is integrated with the lower end of the left inner piece 211 . The right end of the connecting portion 23 is integrated with the lower end of the right inner piece 211 . That is, the connecting portion 23 connects the pair of contact terminals 21 at the bottom wall 12 of the recess 13 .

Each of the pair of joint terminals 24 is provided at the lower end of each of the pair of contact terminals 21 . That is, the left joint terminal 24 is provided at the lower end of the outer piece 212 of the left contact terminal 21 . The right joint terminal 24 is provided at the lower end of the outer piece 212 of the right contact terminal 21 . Also, the pair of joint terminals 24 is positioned outside the pair of contact terminals 21 in the direction in which the pair of contact terminals 21 are arranged (horizontal direction). That is, the pair of joint terminals 24 are arranged at both ends of the contact 2 in the direction in which the pair of contact terminals 21 are arranged (horizontal direction). Each of the pair of connection terminals 24 is positioned on the lower end side of the pair of first wall portions 121 and extends outward in the left-right direction to be exposed from the housing 1 . A lower surface of each of the pair of joint terminals 24 is a joint surface that is joined to the substrate 4 (more specifically, a conductor formed on the surface of the substrate 4) by soldering, for example. That is, the pair of connection terminals 24 are configured to be connected to the substrate 4 . In this embodiment, a plurality of (here, six) connection terminals 24 are arranged on both sides of the housing 1 in the left-right direction.

The plurality of (here, six) contacts 2 are roughly divided into signal terminals 51 and power supply terminals 52 (see FIG. 1). The signal terminal 51 is a terminal through which a signal current (for example, a current of about 0.3 A) flows. The power supply terminal 52 is a terminal through which a power supply current (for example, a current of about 3.0 A) flows. Six contacts 2 are arranged in the longitudinal direction (front-rear direction) of the housing 1, and two power supply terminals 52 are arranged at both front and rear ends of the housing 1 so as to sandwich four signal terminals 51 therebetween. . That is, among the plurality of contacts 2 , the contacts 2 at the extreme ends on both front and rear sides are the power terminals 52 , and the contacts 2 other than the extreme ends are the signal terminals 51 . The width dimension (the dimension in the front-rear direction) of the signal terminal 51 and the power terminal 52 are substantially the same.

The pair of holding metal fittings 3 is a metal molded body made of a metal material such as a copper alloy. The pair of holding metal fittings 3 are provided at both ends of the housing 1 in the longitudinal direction (front-rear direction). By being attached to the housing 1 , the pair of holding metal fittings 3 has a function of increasing the strength of the housing 1 . Each of the pair of holding metal fittings 3 includes one main piece 31, a pair of first outer pieces 32, one second outer piece 33, a pair of first holding terminals 34 (holding terminals), and a pair of second 2 holding terminal 35 (holding terminal), inner piece 36, and hook recess 363 (first hook portion). These are integrally constructed. In the following description, since the pair of holding metal fittings 3 are symmetrical in the front-rear direction, only the holding metal fitting 3 attached to the front end portion of the housing 1 will be described as an example.

The main piece 31 is a portion that covers the front-rear end of the upper surface of the peripheral wall 11 in a substantially U-shape. More specifically, the main piece 31 covers the upper surface of the second wall portion 122 and one end portion (the end portion on the second wall portion 122 side) of the upper surface of each of the pair of first wall portions 121 . More specifically, the main piece 31 has a pair of first main piece portions 311 and one second main piece portion 312 . The pair of first main piece portions 311 covers one longitudinal end portion of the upper surface of each of the pair of first wall portions 121 . More specifically, the pair of first main piece portions 311 covers the upper surface of each of the pair of first wall portions 121 from the front end in the longitudinal direction to a position beyond the power terminal 52 on the front side. In addition, the pair of first main piece portions 311 exposes the inner edge and covers the outer edge on the upper surface of each of the pair of first wall portions 121 . The second main piece portion 312 is a portion that covers the upper surface (for example, substantially the entire upper surface) of the second wall portion 122 . The second main piece portion 312 is connected to the front end portion of each of the pair of first main piece portions 311 .

The pair of first outer pieces 32 are portions extending from each of the pair of first main piece portions 311 of the main piece 31 to the outer side surfaces of each of the pair of first wall portions 121 . The width in the front-rear direction of each of the pair of first outer pieces 32 is, for example, substantially the same as the width in the front-rear direction of each of the pair of first main piece portions 311 . The lower end of each of the pair of first outer pieces 32 is positioned, for example, below the vertical center of each of the pair of first wall portions 121 .

The second outer piece 33 is a portion extending from the second main piece portion 312 of the main piece 31 to the outer surface of the second wall portion 122 . The second outer piece 33 covers substantially the entire outer surface of the second wall portion 122 .

A pair of first holding terminals 34 are terminals extending from each of the pair of first outer pieces 32 . More specifically, the pair of first holding terminals 34 protrude downward along the outer surface of the first wall portion 121 from the lower end of each of the pair of first outer pieces 32 to extend the lower surface of the first wall portion 121 . exposed from The lower end of the first holding terminal 34 on the left side is arranged next to (for example, next to) the connecting terminal 24 on the left side of the power terminal 52 . Similarly, the lower end of the first holding terminal 34 on the right side is arranged next to (for example, next to) the connecting terminal 24 on the right side of the power terminal 52 . A lower surface of each of the pair of first holding terminals 34 is a bonding surface that is bonded to the substrate 4 (more specifically, a conductor formed on the surface of the substrate 4) by soldering, for example.

A pair of second holding terminals 35 are terminals extending from the second outer piece 33 . More specifically, each of the pair of second holding terminals 35 is bent along the lower surface of the second wall portion 122 from both left and right ends of the lower end of the second outer piece 33 and protrudes outward in the left-right direction. The second holding terminal 35 on the left side is arranged next to (for example, adjacent to) the first holding terminal 34 on the left side. Similarly, the second holding terminal 35 on the right side is arranged next to (for example, adjacent to) the first holding terminal 34 on the right side. A lower surface of each of the pair of second holding terminals 35 is a bonding surface that is bonded to the substrate 4 (more specifically, a conductor formed on the surface of the substrate 4) by soldering, for example.

The first holding terminal 34 and the second holding terminal 35 on the left side are aligned in the front-rear direction with the six connecting terminals 24 positioned on the left side. Similarly, the first holding terminal 34 and the second holding terminal 35 on the right side are aligned in the front-rear direction with the six connecting terminals 24 on the right side.

The first holding terminal 34 and the second holding terminal 35 on the left side are bonded to the same pad on the substrate 4 (see FIG. 13A) to which the bonding terminal 24 on the left side of the power supply terminal 52 is bonded. As a result, the metal fitting 3 is electrically connected to the power terminal 52 . As a result, the metal fitting 3 functions as a part of the power terminal 52, and the current capacity of the power terminal 52 increases.

The pitch interval P1 between the power supply terminal 52 (adjacent contacts) and the pair of first holding terminals 34 is smaller than the pitch interval P2 between the contacts 2 (see FIG. 1). A pitch interval P3 between the pair of first holding terminals 34 and the pair of second holding terminals 35 is smaller than the pitch interval P2. This makes it easier to bond the first holding terminal 34 and the second holding terminal 35 to the same pad as the adjacent power supply terminal 52 .

Although the first holding terminal 34 is arranged next to the power terminal 52 in this embodiment, the second holding terminal 35 may be arranged next to the power terminal 52 .

The inner piece 36 is a portion extending from the second main piece portion 312 of the main piece 31 to the inner surface of the second wall portion 122 . The upper half portion 361 of the inner piece 36 covers the taper 124 of the second wall portion 122 , and the lower half portion 362 of the inner piece 36 covers the lower side surface of the taper 124 in the second wall portion 122 . Therefore, the upper half 361 of the inner piece 36 is inclined along the taper 124 and the lower half 362 of the inner piece 36 is substantially perpendicular to the upper surface of the bottom wall 12 .

The inner piece 36 is provided with a hook recess 363 that hooks a later-described protrusion 75 of the mating connector 102 fitted in the recess 13 . The hooking concave portion 363 is provided in a concave shape in the lower half portion 362 of the inner piece 36 . The hook recess 363 has a rectangular shape when viewed from the front and back. The engagement between the hook recess 363 and the projection 75 can increase the pulling force when pulling out the mating connector 102 from the connector 101 .

The structure of the housing 1 will be further described with reference to FIGS. 5 to 7. FIG.

The housing 1 has a spacing recess 125 and an edge recess 126 . Hereinafter, the spacing recess 125 and the marginal recess 126 are also referred to as the recess 125 and the recess 126, respectively.

The recesses 125 are provided on the end surfaces 123a on both sides in the left-right direction of the slits 123 at the extreme ends on both the front and rear sides. The end face 123a is a portion of the peripheral wall 11 that faces the outer piece 212 of each of the pair of contact terminals 21 of the power terminal 52 in the direction in which the pair of contact terminals 21 of the power terminal 52 are arranged (horizontal direction). The recess 125 secures a space between the peripheral wall 11 and the outer piece 212 of each of the pair of contact terminals 21 of the power terminal 52 in the direction in which the pair of contact terminals 21 of the power terminal 52 are arranged. The recess 125 is provided from the lower end of the slit 123 to near the upper end, and is open at the lower end of the slit 123 . In addition, in this embodiment, the concave portion 125 is provided only in the slit 123 at the end of the plurality of slits 123 , but may be provided in other slits 123 .

This concave portion 125 allows each of the pair of contact terminals 21 of the power supply terminal 52 to bend into the concave portion 125 when a load is applied from the mating connector 102 connected to the connector 101 . Thereby, the load acting on the pair of contact terminals 21 from the mating connector 102 can be reduced, and as a result, plastic deformation of the pair of contact terminals 21 due to the load from the mating connector 102 can be suppressed. Since strength is improved by the holding metal fittings 3 around the slits 123 at the extreme ends on both the front and rear sides of the housing 1, the housing 1 is less likely to deform elastically. Therefore, the concave portion 125 allows the load from the mating connector 102 to the pair of contact terminals 21 to escape.

The concave portion 126 is a portion into which the error portion 214 of the contact 2 is fitted. The concave portion 126 is provided at a location facing the gill portion 214 of the contact 2 on both front and rear side surfaces 123 b of each of the plurality of slits 123 . In other words, the recesses 126 are provided at both the left and right ends of the side surfaces 123 b on both the front and rear sides of each slit 123 . Furthermore, in other words, the recessed portion 126 is provided at a portion of the peripheral wall 11 facing the gill portion 214 in the front-rear direction (the direction in which the contacts are arranged). The recess 126 is provided from the lower end of the slit 123 to near the upper end, and is open at the lower end of the slit 123 .

The mating connector 102 of this embodiment is a header (male connector) and includes a housing 60 and a plurality of (here, six) contacts 70 .

The plurality of contacts 70 are held by the housing 60 while being aligned in the front-rear direction. The plurality of contacts 70 correspond to the plurality of contacts 2 of the connector 101 on a one-to-one basis. The plurality of contacts 70 are electrically connected to the pair of contact terminals 21 of the plurality of contacts 2 in a state in which the mating connector 102 is connected to the connector 101 (that is, a state in which the housing 60 is fitted in the recess 13 of the connector 101). Connected. Of the plurality of contacts 70 , the contacts 70 A at the extreme ends on both front and rear sides are used as power supply terminals 92 , and the contacts 70 B other than the extreme ends are used as signal terminals 91 .

The housing 60 is an insulating resin molding. In this embodiment, the housing 60 is an insert-molded product in which a plurality of contacts 70 are inserted. The housing 60 has, for example, a flat rectangular parallelepiped shape elongated in the front-rear direction. Housing 60 is sized to fit in recess 13 of connector 101 . The housing 60 has a top surface (first surface) 66 , a bottom surface (second surface) 61 , a left side surface 62 , a right side surface 63 , a front end surface 64 and a rear end surface 65 . The upper surface 66 and the lower surface 61 extend along the front-rear direction (contact arrangement direction). The left side surface 62 and the right side surface 63 are a pair of side surfaces extending in the front-rear direction and arranged on both left and right sides of the upper surface 66 . The front end surface 64 and the rear end surface 65 are end surfaces on both sides in the front-rear direction.

The housing 60 has a protrusion 67 (see FIGS. 11 and 12). The protrusion 67 protrudes from the lower surface 61 of the housing 60 and extends along the longitudinal direction (front-rear direction) of the lower surface 61 . In this embodiment, two protrusions 67 are provided. One protrusion 67A is formed in a range from one longitudinal end to the center of the lower surface 61 . The other protrusion 67B is formed on the lower surface 61 in a range from the other end in the longitudinal direction to near the center. That is, the two protrusions 67A and 67B are arranged in a line with a gap therebetween. The two protrusions 67A and 67B are provided at the center of the lower surface 61 in the width direction. The longitudinal position of the lower surface 61 where the projection 67 is provided is desirably a position where a load acts on the mating connector 102 when the mating connector 102 is inserted into the recess 13 of the connector 101 with a shift. The projecting portion 67 can prevent the mating connector 102 from breaking in the longitudinal direction of the lower surface 61 when the mating connector 102 is inserted into the concave portion 13 of the connector 101 while being displaced.

The plurality of contacts 70 are metal compacts made of a metal material such as copper alloy. Further, the contact 70 is plated with gold. Note that the contact 70 does not have to be plated with gold. The plurality of contacts 70 are provided on the surface of the housing 60 so as to line up in the longitudinal direction (front-rear direction) of the housing 60 . Among the plurality of contacts 70 , the contacts 70</b>A at the extreme ends on both front and rear sides are provided at both ends of the housing 60 in the longitudinal direction (front and rear direction).

The contact 70 has a pair of contact pieces 71, a connecting portion 72, and a pair of joint terminals 73, which are integrated (see FIG. 9).

Each of the pair of contact pieces 71 has, for example, a rectangular plate shape elongated in the vertical direction. Each of the pair of contact pieces 71 is provided so as to be exposed on the left side surface 62 and the right side surface 63 of the housing 60 . Each of the pair of contact pieces 71 extends from the upper end to the lower end of the left side 62 and the right side 63 . The pair of contact pieces 71 contact the corresponding pair of contact terminals 21 when the connector 101 is connected to the mating connector 102 .

The connecting portion 72 is a portion that connects the pair of contact pieces 71 . The connecting portion 72 has, for example, a rectangular plate shape elongated in the left-right direction. The connecting portion 72 is provided so as to be exposed on the upper surface 66 of the housing 60 . Both left and right ends of the connecting portion 72 are connected to upper ends of the pair of contact pieces 71 .

The pair of connection terminals 73 are, for example, rectangular plates elongated in the left-right direction. One end in the left-right direction of each of the pair of joint terminals 73 is connected to the lower ends of the pair of contact pieces 71 . Each of the pair of joint terminals 73 protrudes outward in the left-right direction from the lower end of each of the left side surface 62 and the right side surface 63 of the housing 60 . The lower surfaces of the pair of joint terminals 73 are joint surfaces that are joined to the substrate 4 (more specifically, conductors formed on the surface of the substrate 4) by soldering, for example.

The contact 70</b>A at the extreme end on both the front and rear sides further has an outer piece 74 , a protrusion 75 (first mating hook), and a notch 78 . The frontmost contact 70A and the rearmost contact 70A have the same structure. Therefore, only the outer piece 74, the projection 75 and the notch 78 of the frontmost contact 70A will be described, and only the outer piece 74, the projection 75 and the notch 78 of the rearmost contact 70A will be described. Description is omitted.

The outer piece 74 has, for example, a rectangular plate shape, and extends from the connecting portion 72 of the frontmost contact 70</b>A to the front end surface 64 of the housing 60 . The outer piece 74 extends from the upper end of the front end face 64 toward the lower end.

The protrusion 75 is provided on the outer surface of the outer piece 74 and protrudes in the thickness direction of the outer piece 74 . The projecting portion 75 is a portion that engages with the engaging recess 363 of the holding metal fitting 3 of the connector 101 when the connector 101 is connected to the mating connector 102 . The protrusion amount W3 of the protrusion 75 is larger than the depth W4 of the hook recess 363 (see FIG. 13B). For example, the protrusion amount W3 is 0.02 m and the depth W4 is 0.015 m. Thereby, when the connector 101 is connected to the mating connector 102 , the protrusion 75 contacts the bottom surface of the hook recess 363 . As a result, the contact 70A at the extreme end and the metal fitting 3 are stably brought into electrical contact with each other.

Further, when the connector 101 is connected to the mating connector 102, the protrusion 75 is vertically aligned with the stepped portion 363a on the upper side of the hook recess 363 and positioned below the stepped portion 363a (see FIG. 14). . Therefore, unless the mating connector 102 is pulled out from the connector 101 with a force greater than a predetermined amount, the projection 75 of the mating connector 102 is caught in the hook recess 363 of the connector 101, and the connection state between the connector 101 and the mating connector 102 is maintained. not released. In other words, the protrusion 75 of the mating connector 102 and the hooking recess 363 of the connector 101 constitute a locking mechanism that can release the connection state between the connector 101 and the mating connector 102 by applying a force greater than or equal to a predetermined amount.

The cutouts 78 are provided on both sides in the width direction (horizontal direction) of the outer piece 74 (see FIG. 8). The cutouts 78 are provided on both left and right sides near the tip (lower end) of the outer piece 74 . The notch 78 is, for example, a semicircular notch. On the other hand, the front end surface 64 of the housing 60 is provided with two fitting portions 641 that fit into the cutout portions 78 on both left and right sides. The fitting portion 641 has a semicircular shape that can be fitted with the notch portion 78 , and is provided as, for example, a stepped portion on the front end surface 64 . Since the cutout portion 78 is caught by the fitting portion 641 , it is possible to prevent the outer piece 74 from being turned up from the front end surface 64 of the housing 60 when the mating connector 102 is pulled out from the connector 101 .

The contacts 70B other than the extreme ends further have a hook recess 77 (second mating hook). That is, the plurality of contacts 70 includes contacts 70B having hook recesses 77. FIG. The hooking recesses 77 are provided on the lateral outer surfaces of each of the pair of contact pieces 71 of the contact 70B. The hook recess 77 is, for example, rectangular in a front view from the left and right direction, and is recessed in the thickness direction of the contact piece 71 . When the connector 101 is connected to the mating connector 102 , the hook recess 77 hooks the projection 215 of the corresponding contact 2 of the connector 101 . More specifically, the stepped portion 77a on the lower side of the hooking recessed portion 77 is vertically aligned with the protrusion 215 and located below the protrusion 215 (see FIG. 13B). The hooking recesses 77 together with the projections 215 of the contacts 2 constitute a locking mechanism that can release the connection state between the connector 101 and the mating connector 102 by applying a force greater than a predetermined force.

As shown in FIGS. 8 and 12, in the front-rear direction (contact arrangement direction), the width D1 of the pair of joint terminals 73 of the contact 70A at the farthest end among the plurality of contacts 70 is equal to the width D1 of the contact 70B other than the farthest end. is larger than the width D2 of the pair of connection terminals 73 of the . Thereby, the bonding strength between the bonding terminal 73 of the contact 70A at the farthest end and the substrate 4 (see FIG. 13A) can be improved.

Also, as shown in FIGS. 8 and 12, the length of the pair of joint terminals 73 of the endmost contact 70A among the plurality of contacts 70 in the left-right direction (direction in which the pair of contact pieces 71 are arranged) is L1 is shorter than the length L2 of the pair of connection terminals 73 of the contact 70B other than the extreme ends. As a result, when the connector 101 is connected to the mating connector 102, the pair of connection terminals 73 of the contacts 70B other than the end can be prevented from coming into contact with the holding metal fittings 3 of the connector 101. FIG.

As shown in FIGS. 9 and 10, the cross-sectional shape of the contacts 70 (70A and 70B) (cross-sectional shape perpendicular to the front-rear direction) is box-shaped. That is, the pair of contact pieces 71 extend linearly in the vertical direction over at least the majority (that is, substantially the entirety) except for the upper and lower ends. In addition, the connecting portion 72 extends linearly in the left-right direction in a large portion (that is, substantially the entire portion) except for at least the left and right ends. Since the cross-sectional shape of the contact 70 is box-shaped, that is, since the cross-sectional shape of the contact 70 does not include a bent or curved portion, the contact piece 71, the connecting portion, and the connecting terminal 73 are formed in this order. 72, the other contact piece 71 and the other connection terminal 73 can be shortened as much as possible, and the conductor resistance of the contact 70 can be reduced.

Further, in the contacts 70 (70A and 70B), the corners 78 where the pair of contact pieces 71 and the connecting portions 72 are connected are chamfered to form, for example, 45-degree inclined surfaces. Accordingly, when the connector 101 and the mating connector 102 are connected, the mating connector 102 can be smoothly fitted into the concave portion 13 without the corner portion 78 being caught by the connector 101 .

As shown in FIG. 10, the pair of contact pieces 71 of the farthest contact 70A are inclined from the lower surface 61 toward the upper surface 66 of the housing 60 in the opposing direction (inward in the left-right direction). As a result, the mating connector 102 (especially the endmost contact 70A) can be easily inserted into and pulled out of the recess 13 of the connector 101 even when the holding metal fittings 3 are provided at both the front and rear end portions of the connector 101 .

(2.3) Connection Device The connector 101 is mounted on a substrate 4 (hereinafter also referred to as "first substrate 41") built in an electronic device such as a smartphone (see FIG. 13A). A mating connector 102 detachably connected to the connector 101 is mounted on another board 4 (hereinafter also referred to as a "second board 42") also built in the electronic device (see FIG. 13A). A first electrical component is mounted on the first substrate 41 and a second electrical component is mounted on the second substrate 42 . The first electrical component is, for example, a battery (first battery), and the second electrical component is also, for example, a battery (second battery).

Then, as shown in FIGS. 13A and 13B, by connecting the connector 101 to the mating connector 102, the first conductor of the first substrate 41 and the second conductor of the second substrate 42 are electrically connected. connected to Specifically, the connector 101 is connected to the mating connector 102 by electrically connecting the plurality of contacts 2 of the connector 101 to the plurality of contacts 70 of the mating connector 102 . At this time, the plurality (eg, four) of signal terminals 51 of the connector 101 are electrically connected to the corresponding plurality (eg, four) of signal terminals 91 of the mating connector 102 . Also, the plurality (eg, two) of power terminals 52 of the connector 101 are electrically connected to the corresponding plurality (eg, two) of power terminals 92 of the mating connector 102 . By connecting the connector 101 to the mating connector 102 in this manner, for example, the first electrical component and the second electrical component are electrically connected via the connector 101 and the mating connector 102 . Thereby, for example, power is supplied from the first battery to the second battery.

In this embodiment, the connector 101, the mating connector 102, the first substrate 41, and the second substrate 42 constitute the connection device 100. As shown in FIG. In other words, the connection device 100 includes a first board 41 mounted with a first electrical component, a second board 42 mounted with a second electrical component, a connector 101 mounted on the first board 41, and a second board. 42 and a mating connector 102 fitted in the recess 13 of the connector 101 . In addition, in FIGS. 13A and 13B, the mating connector 102 is shown upside down and left to right as compared with FIGS. 8 to 10. FIG.

Here, when connecting the connector 101 to the mating connector 102, the pair of contact terminals 21 are pushed outward in the horizontal direction by the contacts 70, as shown in FIG. 13B. Therefore, each of the pair of contact terminals 21 comes into contact with the contact 70 while being elastically deformed outward in the left-right direction. In other words, each of the pair of contact terminals 21 comes into contact with the contact 70 by an elastic force that tends to return to its original state.

More specifically, in this embodiment, the protrusion amount W1 of each protrusion 215 of the pair of contact terminals 21 is larger than the depth W2 of the hook recess 77 of the contact 70B. Therefore, the pair of contact terminals 21 are electrically connected to the contacts 70B by the contact of the protrusions 215 with the bottom surface of the hooking recesses 77, respectively. In this manner, the contact of the protrusion 215 with the bottom surface of the hook recess 77 stabilizes the electrical contact between the pair of contact terminals 21 and the contact 70B. When the connector 101 is pulled out from the mating connector 102 , the protrusion 215 is caught by the stepped portion 77 a of the hook recess 77 . This makes it difficult for the connector 101 to come off from the mating connector 102 .

When the connector 101 is connected to the mating connector 102, the protrusion 75 of the contact 70A at the extreme end of the mating connector 102 is pushed into the hook recess 363 of the holding metal fitting 3 of the connector 101, as shown in FIG. In this state, the projection 75 contacts the bottom surface of the hooking recess 363 because the protrusion amount W3 of the protrusion 75 is larger than the depth W4 of the hooking recess 363 . Due to this contact, the endmost contact 70A of the mating connector 102 is electrically connected to the holding metal fitting 3 of the connector 101 . The electrical contact between the endmost contact 70A and the holding metal fitting 3 is stabilized by the protrusion 75 coming into contact with the bottom surface of the hook recess 363 . When the connector 101 is pulled out from the mating connector 102 , the protrusion 75 is caught by the stepped portion 363 a of the hook recess 363 . This makes it even more difficult for the connector 101 to come off from the mating connector 102 .

In this embodiment, when the connector 101 is pulled out from the mating connector 102 , the protrusion 215 of the contact 2 is hooked on the hooking recess 77 of the contact 70B and the protrusion 75 of the contact 70A is hooked on the hooking recess 363 of the holding metal fitting 3 . This constitutes a high withdrawal structure that requires a high withdrawal force.

As described above, according to the connector 101 according to the present embodiment, the pair of contact terminals 21 of each contact 2 are held by the peripheral wall 11 while facing each other with the recess 13 interposed therebetween, and are connected by the connecting portion 23 . That is, there is no contact terminal rising from the center of the recess 13 . Therefore, the width of the housing 1 (the width in the direction in which the pair of contact terminals 21 are arranged) can be made smaller, and the size of the connector 101 can be reduced.

Further, according to the mating connector 102 of this embodiment, the pair of contact pieces 71 of the mating connector 102 are provided on the pair of side surfaces 62 and 63 of the housing 60 and the connecting portion 72 provided on the top surface 66 of the housing 60 . are connected by That is, there is no contact piece rising from the center of the housing 60 in the width direction (the direction in which the pair of contact pieces 71 are arranged). Therefore, the width of the housing 60 (the width in the direction in which the pair of contact pieces 71 are arranged) can be made smaller, and the size of the mating connector 102 can be reduced. Further, since the outer piece 74 extending from the connecting portion 72 is provided with the protrusion 75 , the pull-out force when pulling out the mating connector 102 from the connector 101 can be increased.

Further, according to the connection device 100 according to the present embodiment, it is possible to provide a connection device having the effect of the connector 101 and the effect of the mating connector 102 .
