Moreover, the definition of the direction described above is not meant to limit the usage patterns of the connector 101 and the other 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 5B. A connector 101 of this embodiment is a socket (female connector) and includes a housing 1 , a plurality of (here, four) contacts 2 , and a pair of mounting brackets 3 .

The housing 1 is a flat rectangular parallelepiped elongated in a first direction (front-to-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 mounting brackets 3 as inserts. The housing 1 has a bottom wall 11 and a peripheral wall 12 . The bottom wall 11 has a plate shape elongated in the first direction and forms the bottom of the housing 1 . The peripheral wall 12 protrudes forward from the peripheral edge of the bottom wall 11 and has a rectangular frame shape in plan view. Hereinafter, "planar view" refers to viewing from the third direction (vertical direction).

Specifically, the peripheral wall 12 is composed of a pair of first peripheral walls 121 and a pair of second peripheral walls 122 . The pair of first peripheral walls 121 are a pair of walls of the peripheral wall 12 along the first direction (front-rear direction). The pair of second peripheral walls 122 are a pair of walls of the peripheral wall 12 along the second direction (horizontal direction). A portion surrounded by the pair of first peripheral walls 121, the pair of second peripheral walls 122, and the bottom wall 11 constitutes a recess 13 in which the housing 1A of the other connector 102 is fitted. That is, the peripheral wall 12 surrounds the recess 13 . The other connector 102 is connected to the connector 101 by fitting the housing 1A of the other connector 102 into the recess 13 .

The housing 1 has four slits 123 spaced apart in the first direction (front-rear direction). Each of the four slits 123 has a rectangular shape elongated in the second direction (horizontal direction) in a plan view, and is an opening penetrating the pair of first peripheral walls 121 in a third direction (vertical direction). are connected to the openings penetrating in the third direction. The four contacts 2 are held by the housing 1 by being pushed into the four slits 123 from below. The term "pushed in" as used herein is a concept including pushing in by applying a certain force or more, that is, press-fitting.

The housing 1 has tapers 124 provided on the periphery of the recess 13 at both ends in the first direction (front-rear direction). The taper 124 is inclined so as to increase the opening area of the recess 13 from one end (lower end) to the other end (upper end) in the third direction (vertical direction). The taper 124 serves as a surface that guides the housing 1A into the recess 13 of the connector 101 when the housing 1A of the other connector 102 is fitted into the recess 13 of the connector 101 .

The contact 2 is a metal molded body made of a metal material such as copper alloy. Also, the contact 2 is plated with gold. Note that the contact 2 may not be plated with gold. As shown in FIGS. 4 to 5B, the contact 2 has a pair of holding portions 21, a bottom portion 23, and a pair of joint portions 24, which are integrally constructed.

Each of the pair of holding portions 21 has an inner piece 211, an outer piece 212, and a connecting piece 213, which are integrally formed. Each of the pair of holding portions 21 has an inverted U shape with one end (upper end) in the third direction as the top when viewed from the front. Hereinafter, "front view" refers to viewing from the first direction (front-rear direction). The pair of holding portions 21 are held by the pair of first peripheral walls 121 so as to be aligned in the second direction (horizontal direction). That is, the pair of holding portions 21 are held by the peripheral wall 12 (first peripheral wall 121) with the recess 13 interposed therebetween. In this embodiment, no obstacle (for example, part of the housing 1) exists between the pair of holding portions 21 (see FIG. 1). That is, the pair of holding portions 21 face each other inside the recess 13 without interposing an obstacle therebetween.

The inner piece 211 has a rectangular plate shape elongated in the third direction (vertical direction) and is exposed in the recess 13 (see FIG. 1). The inner piece 211 is arranged to contact the contact 2A of the other connector 102 when the housing 1A of the other connector 102 is fitted in the recess 13 . Specifically, the contacts 2 are electrically connected to a pair of contacts 2</b>A arranged in the second direction (horizontal direction) of the other connector 102 . The inner piece 211 on the first end side (left side) in the second direction of the contact 2 contacts the contact 2A on the second end side (right side) in the second direction when the housing 1A is fitted in the recess 13 . . Similarly, the inner piece 211 on the second end side (right side) in the second direction of the contact 2 contacts the contact 2A on the first end side (left side) in the second direction when the housing 1A is fitted in the recess 13. do. That is, in this embodiment, the pair of connection portions 22 are the inner pieces 211 of the pair of holding portions 21, respectively.

Also, the inner piece 211 is integral with a projection 214 protruding along the thickness direction (horizontal direction) of the inner piece 211 . When the housing 1A of the other connector 102 is fitted in the recess 13, the protrusion 214 is aligned with the protrusion 251 (described later) of the corresponding contact 2A in the third direction (vertical direction) and positioned above the protrusion 251. (See FIG. 10B). Therefore, unless the other connector 102 is pulled out from the recess 13 with a predetermined force or more, the projection 251 of the contact 2A is caught by the projection 214 of the contact 2, so that the connection between the connector 101 and the other connector 102 is not released. In other words, the protrusion 214 of the contact 2 and the protrusion 251 of the contact 2A constitute a lock mechanism capable of releasing the connection state between the connector 101 and the other connector 102 by applying a force greater than or equal to a predetermined amount. In other words, each of the pair of connection portions 22 (inner pieces 211) has a lock mechanism (protrusion 214) that can release the connection state between the contact 2 and the contact 2A when a force greater than or equal to a predetermined value is applied. .

The outer piece 212 has a rectangular plate shape elongated in the third direction (vertical direction) and faces the inner piece 211 . The outer piece 212 is positioned outside the inner piece 211 in the longitudinal direction (second direction) of the contact 2 . The outer piece 212 is not exposed in the recess 13 and is held by the peripheral wall 12 (first peripheral wall 121). One surface (left surface) of the outer piece 212 on the first end side (left side) in the second direction is in contact with a part of the first peripheral wall 121 on the first end side in the second direction (see FIG. 10A ). ). Similarly, one surface (right surface) of the outer piece 212 on the second end side (right side) in the second direction is in contact with a portion of the first peripheral wall 121 on the second end side in the second direction. That is, the surface of the outer piece 212 opposite to the surface facing the inner piece 211 is in contact with a portion of the peripheral wall 12 (first peripheral wall 121).

The connecting piece 213 connects one end (upper end) of the inner piece 211 in the third direction and one end (upper end) of the outer piece 212 in the third direction. That is, the connecting piece 213 connects one end (upper end) of the inner piece 211 and the outer piece 212 on the side opposite to the bottom portion 23 . Moreover, the connecting piece 213 has an inverted U shape with one end (upper end) in the third direction as the top when viewed from the front.

The bottom portion 23 has a rectangular plate shape elongated in the second direction (horizontal direction). The bottom portion 23 is sandwiched between the pair of holding portions 21 so as to block the opening of the bottom wall 11 of the slit 123 . A first end (left end) in the longitudinal direction of the bottom portion 23 is integrated with one end (lower end) of the inner piece 211 on the first end side (left side) in the second direction. The second end (right end) in the longitudinal direction of the bottom portion 23 is integrated with one end (lower end) of the inner piece 211 on the second end side (right side) in the second direction. That is, the bottom portion 23 connects the pair of holding portions 21 with the bottom wall 11 of the recess portion 13 .

A pair of joint portions 24 are provided at both ends of the contact 2 in the longitudinal direction (second direction). That is, the pair of joint portions 24 are located outside the pair of holding portions 21 in the longitudinal direction of the contact 2 . Both of the pair of joint portions 24 are exposed from the housing 1 in the second direction (horizontal direction). One surface (lower surface) of each of the pair of joint portions 24 is a joint surface that is joined to the substrate 4 by soldering, for example. That is, the pair of joint portions 24 is provided at each of both end portions of the contact 2 in the direction in which the pair of holding portions 21 are arranged (second direction). The pair of joint portions 24 are configured to be joined to the substrate 4 .

Here, in the present embodiment, a plurality of joint portions 24 are arranged on both sides of the housing 1 in the second direction (horizontal direction). The plurality of joint portions 24 are arranged line-symmetrically in plan view with respect to a line passing through the center of the housing 1 in the second direction (see FIG. 2). Therefore, in this embodiment, when the plurality of contacts 2 are joined to the substrate 4 by soldering, for example, the same self-alignment phenomenon tends to occur on both sides of the housing 1 in the second direction. Therefore, in the present embodiment, the self-alignment phenomenon on both sides of the housing 1 in the second direction is less likely to be biased, and the rotation of the connector 101 with respect to the substrate 4 caused by the self-alignment phenomenon is less likely to occur.

The plurality of contacts 2 are roughly divided into first terminals 51 and second terminals 52 (see FIG. 1). Both the first terminal 51 and the second terminal 52 can be used as signal terminals. In this embodiment, among the four contacts 2, there are two first terminals 51 and two second terminals 52. As shown in FIG. Further, in this embodiment, four contacts 2 are arranged in the longitudinal direction (first direction) of the housing 1, and two second terminals 52 are arranged so as to sandwich the two first terminals 51. It is The width dimension (dimension in the first direction (front-rear direction)) of the second terminal 52 is larger than the width dimension of the first terminal 51 . Therefore, the impedance of the second terminal 52 is smaller than the impedance of the first terminal 51 . That is, the rated current of the second terminal 52 is higher than the rated current of the first terminal 51 . Therefore, the second terminal 52 can also be used as a terminal for a power source such as a battery.

Each of the pair of mounting brackets 3 is a metal molded body made of a metal material such as copper alloy. A pair of mounting brackets 3 are provided at both ends of the housing 1 in the longitudinal direction (first direction). The pair of mounting brackets 3 has a function of increasing the strength of the housing 1 by being attached to the housing 1 . Each of the pair of mounting brackets 3 has one main piece 31, a pair of side pieces 32, and a pair of bottom pieces 33, which are integrally constructed. In the following description, of the pair of mounting brackets 3, the mounting bracket 3 attached to the first end (front end) of the housing 1 in the first direction will be described as an example. The mounting bracket 3 attached to the rear end) has the same configuration.

The main piece 31 is attached to the second peripheral wall 122 on one end side (here, the front side) in the first direction. The pair of side pieces 32 protrude toward the inside of the housing 1 (here, rearward) from both ends of the main piece 31 in the second direction (horizontal direction). Each of the pair of side pieces 32 has projecting pieces 321 protruding downward. One end (lower end) of the projecting piece 321 in the third direction is exposed through the bottom wall 11 of the housing 1 (see FIG. 3). One surface (lower surface) of the projecting piece 321 is a bonding surface that is bonded to the substrate 4 by soldering, for example.

The pair of bottom pieces 33 are integral with one end (rear end) of the main piece 31 in the third direction and are bent along the bottom wall 11 of the housing 1 . The bottom piece 33 on the first end side (left side) in the second direction is connected to a plurality of (here, four) joint portions 24 located on the first end side (left side) in the second direction and in the first direction (front-rear direction). are held in the housing 1 so as to be aligned with the . Similarly, the bottom piece 33 on the second end side (right side) in the second direction is connected to the plurality (here, four) of joints 24 located on the second end side (right side) in the second direction and the first direction ( are held in the housing 1 so as to be aligned in the longitudinal direction). One surface (lower surface) of each of the pair of bottom pieces 33 is exposed from the bottom wall 11 of the housing 1 and serves as a bonding surface that is bonded to the substrate 4 by soldering, for example.

(2.2) Other Connector Next, another connector 102 corresponding to the connector 101 of this embodiment will be described in detail with reference to FIGS. 6 to 8B. The other connector 102 of this embodiment is a header (male connector) and includes a housing 1A and a plurality of (here, eight) contacts 2A. In this embodiment, a pair of contacts 2A arranged in the second direction (horizontal direction) constitutes one contact group, and a plurality of (here, four) contact groups are arranged in the first direction (front-rear direction). It is held in the housing 1A. The plurality of contact groups correspond to the plurality of contacts 2 of the connector 101 on a one-to-one basis.

The housing 1A is an insulating resin molded body. In this embodiment, the housing 1A is an insert-molded product in which a plurality of contacts 2A are inserted. The housing 1A has a main portion 14 and a pair of flanges 15. As shown in FIG.

The main portion 14 has a flat rectangular parallelepiped shape elongated in the first direction (front-rear direction). Main portion 14 , including a pair of flanges 15 , is sized to fit in recess 13 of connector 101 . From both sides of the main portion 14 in the second direction (horizontal direction), portions of the plurality of contacts 2A are exposed. In this embodiment, four contacts 2A are held in a state of being aligned in the first direction on the first end side (left side) in the second direction of the main portion 14, and the contact pieces 25 ( (to be described later) and a terminal piece 27 (to be described later) are exposed. Similarly, on the second end side (right side) of the main portion 14 in the second direction, four contacts 2A are held in a state of being aligned in the first direction. 27 is exposed. Here, the pair of contacts 2A arranged in the second direction are held by the solid main portion 14 with a gap therebetween in the second direction. That is, the space between the pair of contacts 2A is filled with the housing 1A.

The plurality of contact groups are electrically connected to the pair of connecting portions 22 of the plurality of contacts 2 in a one-to-one relationship with the housing 1A fitted in the recess 13 of the connector 101 . Therefore, in the present embodiment, the pair of contacts 2A arranged in the second direction (horizontal direction) are electrically connected to the same potential. That is, the other connector 102 has at least one pair of contacts 2A which are held by the housing 1A so as to be partially exposed to the outside of the main portion 14, and which are electrically connected to the pair of connection portions 22 one-to-one. It has one (four in this embodiment).

The pair of flanges 15 protrude from both ends of the main portion 14 in the first direction (front-rear direction). The dimension of each of the pair of flanges 15 in the second direction (horizontal direction) is larger than the dimension of the main portion 14 in the second direction. Specifically, the dimension of each of the pair of flanges 15 in the second direction is such that the contact pieces 25 of the plurality of contacts 2A projecting from the main portion 14 are hidden when viewed from the front. That is, the other connector 102 further has a pair of flanges 15 projecting from both ends of the main portion 14 in a direction (first direction) intersecting the direction (second direction) in which the pair of contacts 2A are arranged. The pair of flanges 15 protrudes outward from the portions (contact pieces 25) of the pair of contacts 2A that come into contact with the pair of connecting portions 22 in the direction (second direction) in which the pair of contacts 2A are arranged. .

The contact 2A is a metal molded body made of a metal material such as copper alloy. Also, the contact 2A is plated with gold. Note that the contact 2A does not have to be plated with gold. The contact 2A has a contact piece 25, a hanging piece 26, and a terminal piece 27, which are integrally constructed (see FIGS. 8A and 8B). The contact piece 25 has a rectangular plate shape. The contact piece 25 is provided so as to be exposed from one surface of the main portion 14 in the second direction (horizontal direction). The contact piece 25 is configured to contact the corresponding connection portion 22 when the housing 1A is fitted in the recess 13 of the connector 101 .

Further, the contact piece 25 is integral with a protrusion 251 that protrudes along the thickness direction (horizontal direction) of the contact piece 25 . When the housing 1A is fitted in the recess 13 of the connector 101, the projection 251 is aligned with the corresponding projection 214 of the contact 2 in the third direction (vertical direction) and positioned below the projection 214 (see FIG. 10B). ). As described above, the protrusion 251, together with the protrusion 214 of the contact 2, constitutes a lock mechanism capable of releasing the connection state between the connector 101 and the other connector 102 by applying a force greater than or equal to a predetermined value.

The hanging piece 26 has a rectangular plate shape elongated in the third direction (vertical direction). The hanging piece 26 faces the contact piece 25 in the second direction (horizontal direction). A first end (upper end) of the hanging piece 26 in the third direction is curved in an inverted U shape and is integrated with a first end (upper end) of the contact piece 25 in the third direction.

The terminal piece 27 has a rectangular plate shape elongated in the second direction (horizontal direction). A first end of the terminal piece 27 in the second direction is integrated with a second end (lower end) of the hanging piece 26 in the third direction. A second end of the terminal piece 27 in the second direction is exposed from the housing 1A. One surface (lower surface) of the terminal piece 27 in the third direction is a bonding surface that is bonded to the substrate 4 by soldering, for example.

Here, in the present embodiment, a plurality of terminal strips 27 are arranged on both sides of the housing 1A in the second direction (horizontal direction). The plurality of terminal strips 27 are arranged line-symmetrically in plan view with respect to a line passing through the center of the housing 1A in the second direction (see FIG. 7A). Therefore, in this embodiment, when the plurality of contacts 2A are joined to the substrate 4 by soldering, for example, the same self-alignment phenomenon tends to occur on both sides of the housing 1A in the second direction. Therefore, in the present embodiment, the self-alignment phenomenon on both sides of the housing 1A in the second direction is less likely to be biased, and the other connector 102 is less likely to rotate with respect to the substrate 4 due to the self-alignment phenomenon.

Like the contacts 2, the contacts 2A are roughly divided into first terminals 51 and second terminals 52. As shown in FIG. In this embodiment, among the eight contacts 2A, there are four first terminals 51 and four second terminals 52 . In this embodiment, four contacts 2A are arranged in the longitudinal direction (first direction) of the housing 1A on both sides of the main portion 14 in the second direction (left-right direction). Two second terminals 52 are arranged on both sides of the main portion 14 in the second direction so as to sandwich the two first terminals 51 . Further, in this embodiment, the other connector 102 does not have the mounting bracket 3 . Instead, the four contacts 2A as the second terminals 52 function as mounting brackets.

In the present embodiment, in both the contacts 2 and 2A, the cross-sectional shape of the first terminal 51 is the same as the cross-sectional shape of the second terminal 52 when viewed from the first direction (front-rear direction). The "same" as used herein is an expression including "substantially the same". Therefore, slight differences in the cross-sectional shapes of the first terminal 51 and the second terminal 52 due to manufacturing errors or variations are within the allowable range.

(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. 10A). Further, another connector 102 corresponding to the connector 101 is mounted on another substrate 4 (hereinafter also referred to as "second substrate 42") similarly built in the electronic device (see FIG. 10A).

Then, as shown in FIGS. 10A and 10B, by connecting the connector 101 to the other 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 other connector 102 by electrically connecting the plurality of contacts 2 of the connector 101 to the plurality of pairs of contacts 2A of the other connector 102 . At this time, the plurality (here, two) first terminals 51 of the connector 101 are electrically connected to the corresponding plurality of pairs (here, two pairs) of the first terminals 51 of the other connector 102 . Also, the plurality (here, two) of the second terminals 52 of the connector 101 are electrically connected to the corresponding plurality of pairs (here, two pairs) of the second terminals 52 of the other connector 102 . That is, in this embodiment, the connector 101 and the other connector 102 constitute the connection device 100 . In other words, the connection device 100 includes a connector 101 and another connector 102 having a pair of contacts 2A electrically connected to the contacts 2. As shown in FIG. In addition, in FIGS. 10A and 10B, the other connector 102 is illustrated in a state in which the front and rear are reversed.

Here, when the connector 101 is connected to the other connector 102, as shown in FIG. 10B, the pair of connection portions 22 (inner pieces 211) are attached to the pair of contacts 2A in the second direction (horizontal direction). pushed. Therefore, the pair of connection portions 22 are brought into contact with the pair of contacts 2A while being elastically deformed in the second direction. Specifically, in the holding portion 21 on the first end side (left side) in the second direction, the inner piece 211 and the outer piece 212 elastically deform leftward. Similarly, in the holding portion 21 on the second end side (right side) in the second direction, the inner piece 211 and the outer piece 212 elastically deform rightward. Therefore, in the state in which the connector 101 is connected to the other connector 102, the pair of connection portions 22 imparts elastic force to the pair of contacts 2A to restore their original states. In other words, the contact 2 has a structure in which the pair of connection portions 22 is pushed by the pair of contacts 2A, thereby bending outward so that the distance between the pair of connection portions 22 increases.

A part of the first peripheral wall 121 that is in contact with the outer piece 212 is pushed by the elastically deformed outer piece 212 and elastically deforms slightly. Specifically, this wall has a dimension of several millimeters in the lateral direction (second direction) of the housing 1 and a dimension of several hundred μm in the lateral direction (second direction) of the first peripheral wall 121. Then, it is elastically deformed by several μm to several tens of μm.

(3) Advantages In the connector 101 of this embodiment, each contact 2 has a pair of connection portions 22 . In the connector 101 of this embodiment, a pair of holding portions 21 including a pair of connecting portions 22 are held by the housing 1 . That is, in the connector 101 of this embodiment, one contact 2 has two electrical contacts, and the two contacts are held by the housing 1 . Therefore, when the other connector 102 is connected to the connector 101 , the pair of connection portions 22 that come into contact with the other connector side contacts 2A of the other connector 102 are both held by the housing 1 . Therefore, the connector 101 of the present embodiment can improve the strength of the contacts 2 in a state of being electrically connected to the other connector side contacts 2A of the other connector 102 .

Here, in the connector described in Patent Document 1 (hereinafter referred to as "comparative connector"), the socket-side terminals (contacts) are similar to the connector 101 of the present embodiment, header-side terminals (other connector-side contacts). It has two electrical contacts that make contact with the However, in the connector of the comparative example, one of the two contacts of the contact is not held by the housing and is freely movable with respect to the housing. On the other hand, in the connector 101 of this embodiment, the pair of connection portions 22 of the contacts 2 are both held by the housing 1 . Therefore, in the connector 101 of this embodiment, when the other connector 102 is connected to the connector 101, the housing 1 can receive the force of the pair of connecting portions 22 being pushed by the other connector side contacts 2A.

That is, the connector 101 of the present embodiment has a stronger force with which the other connector side contact 2A is sandwiched between the pair of connecting portions 22 than the connector of the comparative example. For this reason, the connector 101 of the present embodiment also has the advantage that the other connector 102 is less likely to come off from the connector 101 even if the other connector 102 receives an external force in a direction that causes the other connector 102 to be displaced from the connector 101 .

(4) Modifications In the connector 101 of the present embodiment, the longitudinal dimension of the first peripheral wall 121 is larger than the longitudinal dimension of the second peripheral wall 122, but other configurations are possible. For example, the longitudinal dimension of the first peripheral wall 121 may be smaller than the longitudinal dimension of the second peripheral wall 122 . Also, the longitudinal dimension of the first peripheral wall 121 may be substantially the same as the longitudinal dimension of the second peripheral wall 122 . In this case, the other connector 102 of this embodiment is also appropriately changed according to the shape of the connector 101 .

In this embodiment, the contact 2 is fixed to the substrate 4 by soldering one surface (lower surface) of each of the pair of joint portions 24 to the substrate 4, but other configurations may be used. For example, the contact 2 may be fixed to the substrate 4 by soldering one surface (lower surface) of the bottom portion 23 to the substrate 4 in addition to the pair of joint portions 24 . Alternatively, the contact 2 may be fixed to the substrate 4 by soldering only one surface (lower surface) of the bottom portion 23 to the substrate 4 .

In this embodiment, the pair of contacts 2A arranged in the second direction (horizontal direction) of the other connector 102 may be integrated. This configuration can be realized, for example, by connecting the hanging pieces 26 of the pair of contacts 2A arranged in the second direction to form one metal compact. In this case, the other connector 102 has four contacts 2A arranged in the first direction (front-rear direction).

In this embodiment, the connector 101 has two contacts 2 as the first terminals 51 and two contacts 2 as the second terminals 52 , but the number of contacts 2 is not limited. For example, the connector 101 may have three or more contacts 2 as first terminals 51 or three or more contacts 2 as second terminals 52 . Alternatively, the connector 101 may have only the contact 2 as the first terminal 51, for example. Alternatively, the connector 101 may have only the contact 2 as the second terminal 52, for example.

In this embodiment, the contacts 2 are held by the housing 1 by being pushed into the slits 123 from below, but other configurations may be used. For example, the housing 1 may be an insert-molded product in which the contacts 2 are inserted. In this configuration, slit 123 is not required.

In this embodiment, the other connector 102 does not have the mounting bracket 3, but may have the mounting bracket 3. FIG. In this case, the mounting brackets 3 may be provided, for example, at both ends of the main portion 14 in the longitudinal direction (second direction). Moreover, in this case, the shape of the mounting bracket 3 may be appropriately changed according to the shape of the other connector 102 .

In other words, the contact 2A as the first terminal 51 has a larger projecting force from the housing 1A than the contact 2A as the second terminal 52 . In this way, in the contact 2A as the first terminal 51, by increasing the amount of protrusion of the terminal piece 27 from the housing 1A and by increasing the joint area of the terminal piece 27 with respect to the substrate 4, the contact 2A can be positioned with respect to the substrate 4. can be fixed more firmly.

According to this configuration, when the other connector (102) is connected to the connector (101), even if it is pushed by the other connector side contact (2A), the outer piece (212) is less likely to elastically deform excessively. However, this configuration is not essential, and the opposite side of the outer piece (212) may not be in contact with a portion of the peripheral wall (12).

In the connector (101) of the seventh aspect, in any one of the fourth to sixth aspects, the pair of holding portions (21) face each other inside the recess (13) without interposing an obstacle. .

According to this configuration, the distance between the pair of holding portions (21) can be reduced compared to the case where an obstacle exists inside the recess (13). Therefore, according to this configuration, it is possible to reduce the size of the contact (2), and as a result, it is possible to reduce the size of the housing (1) that holds the contact (2). However, this configuration is not essential, and the pair of holding parts (21) may face each other with a part of the housing (1) interposed inside the recess (13), for example.

In the connector (101) of the eighth aspect, in the first aspect, the contact (2) further comprises a pair of mating portions (24) and a bottom portion (23).

Therefore, according to this configuration, it is possible to improve the reliability of the electrical connection between the contact (2) and the connector-side contact (2A). Moreover, according to this configuration, the pair of joints (24) is fixed to the substrate (4) outside the pair of holding portions (21) in the direction in which the pair of holding portions (21) are arranged. Therefore, according to this configuration, when the other connector (102) is connected to the connector (101), the connecting part (22) receives the force of being pushed by the other connector side contact (2A) at the joining part (24). Is possible. Therefore, according to this configuration, it is possible to further improve the reliability of the electrical connection between the contact (2) and the connector-side contact (2A). However, this configuration is not essential, and for example, the pair of holding parts (21) may not have the inner piece (211), the outer piece (212), and the connecting piece (213). Also, for example, the pair of joints (24) may be inside the pair of holding parts (21) in the direction in which the pair of holding parts (21) are arranged.
