In the following, the longitudinal direction of each of the housings 1,60 of the connector 101 and the mating connector 102 is the front-rear direction (first direction), the lateral direction of the housings 1,60 is the left-right direction (second direction), and the housings 1,60. The thickness direction will be described as the vertical direction (third direction). Note that FIGS. 1 to 14 show arrows indicating these directions (up, down, left, right, front, back) as viewed from the center of the connector 101 or the mating connector 102, but these arrows are simply. It is described only for the purpose of assisting the explanation, and does not accompany the substance. Further, the above-mentioned provision of the direction does not mean that the usage pattern of the connector 101 and the mating connector 102 of the present embodiment is limited.

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

The housing 1 is a resin molded body having a flat rectangular parallelepiped shape long in the front-rear direction and made of an insulating resin material (for example, LCP (Liquid Crystal Polymer) resin). In the present embodiment, the housing 1 is an insert molded product having a pair of holding metal fittings 3 as an insert product. The housing 1 has a bottom wall 12 and a peripheral wall 11. The bottom wall 12 has a plate shape long in the front-rear direction and constitutes the bottom portion of the housing 1. The peripheral wall 11 projects upward from the peripheral edge of the bottom wall 12 and has a rectangular frame shape in a 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 wall portions 121 is a pair of wall portions along the front-rear direction of the peripheral wall 11. The pair of second wall portions 122 is a pair of wall portions along the left-right direction of the peripheral wall 11. In other words, the pair of second wall portions 122 are wall portions that intersect (for example, orthogonally) with each other in the front-rear direction. The 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 into which the housing 60 of the mating connector 102 fits. That is, the peripheral wall 11 surrounds the recess 13. When the housing 60 of the mating connector 102 fits into the recess 13, the mating connector 102 is connected to the connector 101.

The housing 1 has a plurality of slits 123 (here, six) arranged at intervals in the front-rear direction. Each of the six slits 123 has a rectangular shape that is long in the horizontal direction in a plan view, and the pair of first penetrating portions 15 that penetrate the pair of first wall portions 121 in the vertical direction and the bottom wall 12 in the vertical direction. It is composed of a second penetrating portion 16 penetrating through. Each of the six contacts 2 is held in 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 the lower end to the upper end. The taper 124 is a surface that guides the mating connector 102 to the recess 13 when the mating connector 102 is fitted into the recess 13 of the connector 101. 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 molded body made of a metal material such as a copper alloy. The contact 2 is gold-plated. The contact 2 may not be gold-plated. 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 joining terminals 24, which are integrally configured.

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

The inner piece 211 has, for example, a rectangular plate shape that is long in the vertical direction and is exposed in the recess 13 (see FIG. 1). The inner piece 211 is arranged so as to come into contact with the contact 70 described later of the mating connector 102 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). ..

A protrusion 215 (second hooking portion) projecting in the thickness direction (left-right direction) of the inner piece 211 is integrally provided on the inner side surface of the inner piece 211. The above-mentioned inner surface is an inner surface in a direction (left-right 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 in the direction opposite to each other. The protrusion 215 is a portion that is hooked with the hook recess 77 (second mating side hooking portion) of the contact 70B described later of the mating connector 102 in a state where the connector 101 is connected to the mating connector 102. The protrusion amount W1 of the protrusion 215 is larger than the depth W2 of the hook recess 77. For example, the protrusion amount W1 is 0.02 m, and the depth W2 is 0.015. As a result, when the connector 101 is connected to the mating connector 102, the protrusion 215 comes into contact with the bottom surface of the hook recess 77. As a result, the pair of contact terminals 21 and the contact 70B are in stable electrical contact.

More specifically, the protrusion 215 is vertically aligned with the step portion 77a of the hook recess 77 and is located above the step portion 77a in a state where the connector 101 is connected to the mating connector 102 (see FIG. 13B). ). Therefore, unless the mating connector 102 is pulled out from the connector 101 with a force equal to or greater than a predetermined value, the stepped portion 77a of the contact 70B is caught by the protruding portion 215 of the contact 2, and the connection state between the connector 101 and the mating connector 102 is released. Not done. That is, the protrusion 215 of the contact 2 and the hook recess 77 of the contact 70B form a lock mechanism capable of releasing the connection state between the connector 101 and the mating connector 102 by applying a force equal to or higher than a predetermined value.

The outer piece 212 has, for example, a rectangular plate shape that is long 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 each of the pair of contact terminals 21 is arranged (left-right direction). The outer piece 212 is not exposed to the recess 13 and is held by the peripheral wall 11 (first wall portion 121). Further, the left surface (outer surface) of the left outer piece 212 is arranged at a distance from the first wall portion 121 on the left side (see FIG. 7). Similarly, the right surface (outer surface) of the outer piece 212 on the right side is arranged at a distance from the first wall portion 121 on the right side. That is, in the outer piece 212, a surface (outer surface) opposite to the surface facing the inner piece 211 is arranged at a distance from the peripheral wall 11.

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

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

The connecting portion 23 has, for example, a rectangular plate shape that is long in the left-right direction. The connecting portion 23 is located between the pair of contact terminals 21 so as to close 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 with the bottom wall 12 of the recess 13.

Each of the pair of joining 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. Further, the pair of joining terminals 24 are located outside the pair of contact terminals 21 in the direction in which each of the pair of contact terminals 21 is arranged (left-right direction). That is, the pair of joining terminals 24 are arranged at both ends in the direction (horizontal direction) in which each of the pair of contact terminals 21 in the contact 2 is arranged. Each of the pair of joining terminals 24 is located on the lower end side of the pair of first wall portions 121, extends outward in the left-right direction, and is exposed from the housing 1. The lower surface of each of the pair of bonding terminals 24 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. That is, the pair of bonding terminals 24 are configured to be bonded to the substrate 4. In the present embodiment, a plurality of (six here) joining terminals 24 are arranged on both sides of the housing 1 in the left-right direction.

A plurality of (six in this case) contacts 2 are roughly classified into a signal terminal 51 and a power supply terminal 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-back 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 the four signal terminals 51. .. That is, of the plurality of contacts 2, the contact 2 at the end on both the front and rear sides is the power supply terminal 52, and the contact 2 other than the end is the signal terminal 51. The width dimensions (dimensions in the front-rear direction) of the signal terminal 51 and the power supply terminal 52 are substantially the same as each other.

The pair of holding metal fittings 3 are metal molded bodies 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), respectively. The pair of holding metal fittings 3 have a function of increasing the strength of the housing 1 by being attached to 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 first holding terminals. 2 It has a holding terminal 35 (holding terminal), an inner piece 36, and a hook recess 363 (first hook portion). These are integrally configured. In the following description, since the pair of holding metal fittings 3 have symmetrical shapes 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 of the pair of holding metal fittings 3.

The main piece 31 is a portion that covers the end portion of the upper surface of the peripheral wall 11 in the front-rear direction in a substantially U-shape. More specifically, the main piece 31 covers the upper surface of the second wall portion 122 and one end of each upper surface of the pair of first wall portions 121 (end portion on the second wall portion 122 side). 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 end portion in the longitudinal direction on the upper surface of each of the pair of first wall portions 121. More specifically, the pair of first main piece portions 311 covers from the front end in the longitudinal direction to a position beyond the power supply terminal 52 on the front side on the upper surface of each of the pair of first wall portions 121. Further, 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 parts 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 surfaces of each of the pair of first wall portions 121. The width of each of the pair of first outer pieces 32 in the front-rear direction is, for example, substantially the same as the width of each of the pair of first main piece portions 311 in the front-rear direction. The lower ends of each of the pair of first outer pieces 32 are located, for example, below the center of each of the pair of first wall portions 121 in the vertical direction.

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 almost the entire outer surface of the second wall portion 122.

The 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 project downward from the lower ends of each of the pair of first outer pieces 32 along the outer surface of the first wall portion 121, and the lower surface of the first wall portion 121. Is exposed from. The lower end of the first holding terminal 34 on the left side is arranged next to the joint terminal 24 on the left side of the power supply terminal 52 (for example, next to the front). Similarly, the lower end of the first holding terminal 34 on the right side is arranged next to the joint terminal 24 on the right side of the power supply terminal 52 (for example, next to the front). The lower surface of each of the pair of first holding terminals 34 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.

The 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 from the left and right ends of the lower end of the second outer piece 33 along the lower surface of the second wall portion 122, and projects outward in the left-right direction. The second holding terminal 35 on the left side is arranged next to the first holding terminal 34 on the left side (for example, next to the front). Similarly, the second holding terminal 35 on the right side is arranged next to the first holding terminal 34 on the right side (for example, next to the front). The lower surface of each of the pair of second holding terminals 35 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.

The first holding terminal 34 and the second holding terminal 35 on the left side are arranged in the front-rear direction with the six joining terminals 24 located 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 joining terminals 24 located on the right side.

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

The pitch interval P1 between the power supply terminal 52 (adjacent contact) and the pair of first holding terminals 34 is smaller than the pitch interval P2 of the plurality of contacts 2 (see FIG. 1). The 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 join the first holding terminal 34 and the second holding terminal 35 to the same pad as the power supply terminal 52 adjacent to them.

In the present embodiment, the first holding terminal 34 is arranged next to the power supply terminal 52, but the second holding terminal 35 may be arranged next to the power supply 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 side surface of the second wall portion 122. The upper half 361 of the inner piece 36 covers the taper 124 of the second wall 122, and the lower half 362 of the inner piece 36 covers the lower side surface of the taper 124 of the second wall 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 is hooked with a protrusion 75 described later of the mating connector 102 fitted in the recess 13. The hook recess 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. By catching the hook recess 363 and the protrusion 75, the pulling force when pulling out the mating connector 102 from the connector 101 can be increased.

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

The housing 1 has a recess 125 for spacing and a recess 126 for gills. Hereinafter, the recess 125 for spacing and the recess 126 for the elastic portion are also referred to as the recess 125 and the recess 126, respectively.

The recess 125 is provided on both end faces 123a in the left-right direction in the slit 123 at the end on both front and rear sides. The end surface 123a is a portion of the peripheral wall 11 facing the outer piece 212 of each of the pair of contact terminals 21 of the power supply terminal 52 in the direction (horizontal direction) in which the pair of contact terminals 21 of the power supply terminal 52 are lined up. The recess 125 secures a distance between the peripheral wall 11 and the outer piece 212 of each of the pair of contact terminals 21 of the power supply terminal 52 in the direction in which each of the pair of contact terminals 21 of the power supply terminal 52 is lined up. The recess 125 is provided from the lower end to the vicinity of the upper end of the slit 123, and is opened at the lower end of the slit 123. In the present embodiment, the recess 125 is provided only in the slit 123 at the end of the plurality of slits 123, but may be provided in another slit 123.

The recess 125 allows each of the pair of contact terminals 21 of the power supply terminal 52 to bend into the recess 125 when a load is received from the mating connector 102 connected to the connector 101. As a result, the load acting on the pair of contact terminals 21 from the mating connector 102 can be reduced, and as a result, the pair of contact terminals 21 can be prevented from being plastically deformed by the load from the mating connector 102. Since the strength of the holding metal fittings 3 is improved around the slits 123 at the outermost ends on both the front and rear sides of the housing 1, the housing 1 is unlikely to be elastically deformed. For this reason, the recess 125 makes it possible to release the load from the mating connector 102 to the pair of contact terminals 21.

The recess 126 is a portion where the gill portion 214 of the contact 2 fits. The recess 126 is provided at a position facing the gill portion 214 of the contact 2 on the front and rear side surfaces 123b of each of the plurality of slits 123. In other words, the recesses 126 are provided at the left and right ends on the front and rear side surfaces 123b of each slit 123. Further, in other words, the recess 126 is provided at a position facing the elliptical portion 214 on the peripheral wall 11 in the front-rear direction (contact alignment direction). The recess 126 is provided from the lower end to the vicinity of the upper end of the slit 123, and is opened at the lower end of the slit 123.

(2.2) Mating Connector Next, the mating connector 102 that is detachably connected to the connector 101 of the present embodiment will be described in detail with reference to FIGS. 8 to 12. The mating connector 102 of the present embodiment is a header (male connector), and includes a housing 60 and a plurality of (six in this case) contacts 70.

The plurality of contacts 70 are held in the housing 60 in a state of being arranged in the front-rear direction. Each of the plurality of contacts 70 has a one-to-one correspondence with the plurality of contacts 2 of the connector 101. The plurality of contacts 70 are electrically connected to the pair of contact terminals 21 of the plurality of contacts 2 in a state where the mating connector 102 is connected to the connector 101 (that is, the housing 60 is fitted in the recess 13 of the connector 101). Be connected. Of the plurality of contacts 70, the contact 70A at the end on both the front and rear sides is used as the power supply terminal 92, and the contact 70B other than the end is used as the signal terminal 91.

The housing 60 is a resin molded body having an insulating property. In the present embodiment, the housing 60 is an insert molded product having a plurality of contacts 70 as insert products. The housing 60 has, for example, a flat rectangular parallelepiped shape that is long in the front-rear direction. The housing 60 has a size that fits into the recess 13 of the connector 101. The housing 60 has an upper surface (first surface) 66, a lower 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 alignment direction). The left side surface 62 and the right side surface 63 are a pair of side surfaces extending along the front-rear direction and arranged on the 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-back direction) of the lower surface 61. In this embodiment, two protrusions 67 are provided. One protrusion 67A is formed on the lower surface 61 in a range from one end in the longitudinal direction to the center. 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 row with an interval. The two protrusions 67A and 67B are provided at the center of the lower surface 61 in the width direction. It is desirable that the position in the longitudinal direction of the lower surface 61 where the protrusion 67 is provided is 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 in a misaligned manner. The protrusion 67 can prevent the mating connector 102 from breaking in the middle of the lower surface 61 in the longitudinal direction when the mating connector 102 is inserted into the recess 13 of the connector 101 in a misaligned manner.

The plurality of contacts 70 are metal molded bodies made of a metal material such as a copper alloy. Further, the contact 70 is gold-plated. The contact 70 may not be gold-plated. The plurality of contacts 70 are provided on the surface of the housing 60 so as to be arranged in the longitudinal direction (front-back direction) of the housing 60. Of the plurality of contacts 70, the outermost contacts 70A on both the front and rear sides are provided at both ends in the longitudinal direction (front and rear direction) of the housing 60.

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

Each of the pair of contact pieces 71 has, for example, a rectangular plate shape that is long 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 surface 62 and the right side surface 63. The pair of contact pieces 71 come into contact with the corresponding pair of contact terminals 21 in a state where 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 that is long 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. The left and right ends of the connecting portion 72 are connected to the upper ends of the pair of contact pieces 71.

The pair of joining terminals 73 have, for example, a rectangular plate shape that is long in the left-right direction. One end of each of the pair of joining terminals 73 in the left-right direction is connected to the lower end of the pair of contact pieces 71. Each of the pair of joining terminals 73 projects outward in the left-right direction from the lower ends of the left side surface 62 and the right side surface 63 of the housing 60. The lower surface of the pair of joining terminals 73 is a joining surface that is joined to the substrate 4 (more specifically, a conductor formed on the surface of the substrate 4) by soldering, for example.

The outermost contacts 70A on both front and rear sides further have an outer piece 74, a protrusion 75 (first mating side hooking portion), and a notch 78. The frontmost contact 70A and the rearmost contact 70A have the same structure. Therefore, only the outer piece 74, the protrusion 75 and the notch 78 of the frontmost contact 70A will be described, and the outer piece 74, the protrusion 75 and the notch 78 of the rearmost contact 70A will be described. The 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 70A to the front end surface 64 of the housing 60. The outer piece 74 extends from the upper end to the lower end of the front end surface 64.

The protrusion 75 is provided on the outer surface of the outer piece 74 and projects in the thickness direction of the outer piece 74. The protrusion 75 is a portion that is hooked on the hook recess 363 of the holding metal fitting 3 of the connector 101 in a state where 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. As a result, when the connector 101 is connected to the mating connector 102, the protrusion 75 comes into contact with the bottom surface of the hook recess 363. As a result, the endmost contact 70A and the holding metal fitting 3 are in stable electrical contact.

Further, the protrusion 75 is vertically aligned with the step portion 363a on the upper side of the hook recess 363 and is located below the step portion 363a in a state where the connector 101 is connected to the mating connector 102 (see FIG. 14). .. Therefore, unless the mating connector 102 is pulled out from the connector 101 with a force equal to or greater than a predetermined value, the protruding portion 75 of the mating connector 102 of the hooking recess 363 of the connector 101 is caught, and the connection state between the connector 101 and the mating connector 102 is changed. It will not be released. That is, the protrusion 75 of the mating connector 102 and the hooking recess 363 of the connector 101 form a locking mechanism capable of releasing the connection state between the connector 101 and the mating connector 102 by applying a force equal to or higher than a predetermined value.

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

The contact 70B other than the end end further has a hook recess 77 (second mating hook portion). That is, the plurality of contacts 70 include the contact 70B having the hook recess 77. The hook recess 77 is provided on the lateral outer surface of each of the pair of contact pieces 71 of the contact 70B in the left-right direction. The hook recess 77 is, for example, rectangular when viewed from the left and right, and is recessed in the contact piece 71 in the thickness direction. The hook recess 77 is hooked with the protrusion 215 of the corresponding contact 2 of the connector 101 in a state where the connector 101 is connected to the mating connector 102. More specifically, the step portion 77a on the lower side of the hook recess 77 is aligned vertically with the protrusion 215 and is located below the protrusion 215 (see FIG. 13B). The hook recess 77 constitutes a lock mechanism capable of releasing the connection state between the connector 101 and the mating connector 102 by applying a force equal to or higher than a predetermined force together with the protrusion 215 of the contact 2.

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

Further, as shown in FIGS. 8 and 12, in the left-right direction (each arrangement direction of the pair of contact pieces 71), the length of the pair of joining terminals 73 of the endmost contact 70A among the plurality of contacts 70. L1 is shorter than the length L2 of the pair of joining terminals 73 of the contacts 70B other than the most extreme end. Thereby, when the connector 101 is connected to the mating connector 102, it is possible to prevent the pair of joining terminals 73 of the contacts 70B other than the end end from coming into contact with the holding metal fitting 3 of the connector 101.

As shown in FIGS. 9 and 10, the cross-sectional shape (cross-sectional shape orthogonal to the front-rear direction) of the contacts 70 (70A and 70B) is box-shaped. That is, most of the pair of contact pieces 71 (that is, almost the entire surface) excluding at least the upper and lower ends extend linearly in the vertical direction. In addition, most of the connecting portion 72 (that is, almost the entire portion) excluding at least the left and right end portions extends linearly in the left-right direction. In this way, the cross-sectional shape of the contact 70 is box-shaped, that is, there is no bent or curved portion in the cross-sectional shape of the contact 70, so that one contact piece 71 and the connecting portion are sequentially arranged from one joining terminal 73. 72, the path length of the conductive path leading to the other contact piece 71 and the other joint 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 corner portion 78 connecting the pair of contact pieces 71 and the connecting portion 72 is chamfered to form, for example, an inclined surface of 45 degrees. As a result, when the connector 101 and the mating connector 102 are connected, the mating connector 102 can be smoothly fitted into the recess 13 without the corner portion 78 being caught in the connector 101.

As shown in FIG. 10, the pair of contact pieces 71 of the contact 70A at the outermost end are inclined from the lower surface 61 of the housing 60 toward the upper surface 66 in the opposite direction (inside in the left-right direction). As a result, even when the holding metal fittings 3 are provided at both the front and rear ends of the connector 101, the mating connector 102 (particularly the contact 70A at the end) can be easily inserted and removed from the recess 13 of the connector 101.

(2.3) 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). Further, the mating connector 102 that is detachably connected to the connector 101 is mounted on another board 4 (hereinafter, also referred to as “second board 42”) also built in the electronic device (see FIG. 13A). The first electric component is mounted on the first board 41, and the second electric component is mounted on the second board 42. The first electric component is, for example, a battery (first battery), and the second electric 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 to each other. 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 of (for example, four) signal terminals 51 of the connector 101 are electrically connected to the corresponding plurality of (for example, four) signal terminals 91 of the mating connector 102, respectively. Further, the plurality of (for example, two) power supply terminals 52 of the connector 101 are electrically connected to the corresponding plurality of (for example, two) power supply terminals 92 of the mating connector 102, respectively. By connecting the connector 101 to the mating connector 102 in this way, for example, the first electrical component and the second electrical component are electrically connected via the connector 101 and the mating connector 102. As a result, for example, electric power is supplied from the first battery to the second battery.

In the present embodiment, the connecting device 100 is composed of the connector 101, the mating connector 102, the first board 41, and the second board 42. In other words, the connector 100 includes a first board 41 on which the first electric component is mounted, a second board 42 on which the second electric component is mounted, a connector 101 mounted on the first board 41, and a second board. It includes a mating connector 102 that is mounted on the 42 and fitted into the recess 13 of the connector 101. Note that, in FIGS. 13A and 13B, the mating connector 102 is shown in an inverted state in the vertical and horizontal directions as compared with FIGS. 8 to 10.

Here, when the connector 101 is connected to the mating connector 102, as shown in FIG. 13B, the pair of contact terminals 21 are pushed outward by the contact 70 in the left-right direction. Therefore, each of the pair of contact terminals 21 comes into contact with the contact 70 in a state of being elastically deformed in the outward direction 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 tries to return to the original state.

More specifically, in the present 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, when the protrusion 215 comes into contact with the bottom surface of the hook recess 77, the pair of contact terminals 21 are electrically connected to the contact 70B, respectively. In this way, when the protrusion 215 comes into contact with the bottom surface of the hook recess 77, the electrical contact between the pair of contact terminals 21 and the contact 70B is stabilized. When the connector 101 is pulled out from the mating connector 102, the protrusion 215 is caught by the step portion 77a of the hook recess 77. This makes it difficult for the connector 101 to come off from the mating connector 102.

Further, when the connector 101 is connected to the mating connector 102, as shown in FIG. 14, the protrusion 75 of the contact 70A at the end of the mating connector 102 is pushed into the hook recess 363 of the holding metal fitting 3 of the connector 101. In this state, since the protrusion amount W3 of the protrusion 75 is larger than the depth W4 of the hook recess 363, the protrusion 75 comes into contact with the bottom surface of the hook recess 363. By this contact, the contact 70A at the end of the mating connector 102 is electrically connected to the holding metal fitting 3 of the connector 101. When the protrusion 75 comes into contact with the bottom surface of the hook recess 363, the electrical contact between the endmost contact 70A and the holding metal fitting 3 is stabilized. When the connector 101 is pulled out from the mating connector 102, the protrusion 75 is caught by the step portion 363a of the hook recess 363. As a result, the connector 101 is more difficult to disconnect from the mating connector 102.

In the present embodiment, when the connector 101 is pulled out from the mating connector 102, the protrusion 215 of the contact 2 is caught in the hook recess 77 of the contact 70B, and the protrusion 75 of the contact 70A is caught in the hook recess 363 of the holding metal fitting 3. As a result, a high extraction structure that requires a high extraction force is constructed.

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 in a state of facing each other with the recess 13 sandwiched therein, and are connected by the connecting portion 23. That is, there is no contact terminal that rises from the center of the recess 13. Therefore, the width of the housing 1 (the width in the direction in which each of the pair of contact terminals 21 are arranged) can be made smaller, and the connector 101 can be made smaller.

Further, according to the mating connector 102 according to the present 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 upper surface 66 of the housing 60. It is connected by. That is, there is no contact piece rising from the center in the width direction of the housing 60 (the direction in which each of the pair of contact pieces 71 is arranged). Therefore, the width of the housing 60 (the width in the direction in which each of the pair of contact pieces 71 are arranged) can be made smaller, and the mating connector 102 can be made smaller. Further, since the protrusion 75 is provided on the outer piece 74 extending from the connecting portion 72, the pulling force when pulling out the mating connector 102 from the connector 101 can be increased.

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