(1) Outline Hereinafter, the mounting bracket 5 and the connector 101 to which the mounting bracket 5 is mounted will be described with reference to FIGS. 1 to 6B. The connector 101 of this embodiment is attached to a substrate 7 (see FIG. 13) such as a printed wiring board or a flexible printed wiring board. The connector 101 is used for electrically connecting a plurality of substrates 7 mounted on a mobile terminal such as a smartphone. Of course, the purpose of the connector 101 is not limited, and the connector 101 may be used for an electronic device other than a portable terminal such as a camera module. In addition, the connector 101 is not limited to an application for electrically connecting a plurality of substrates 7, and is electrically connected between a plurality of components, for example, between the substrate 7 and a display or between the substrate 7 and a battery. Any application can be used.

  The connector 101 includes a housing 1, a plurality of contacts 2, and a mounting bracket 5. The housing 1 holds a plurality of contacts 2. The housing 1 has a bottom wall 11 and a peripheral wall 12 surrounding the bottom wall 11. The peripheral wall 12 includes a pair of first peripheral walls 121 and a pair of second peripheral walls 122. At least one of the pair of first peripheral walls 121 holds the plurality of contacts 2 in a state in which the contacts 2 are arranged in the arrangement direction (longitudinal direction of the first peripheral wall 121). The pair of second peripheral walls 122 connect the ends of the pair of first peripheral walls 121 to each other.

  The dimension in the thickness direction of the housing 1 is, for example, several mm or less. Moreover, the dimension of the longitudinal direction of the housing 1 is a dozen mm, for example. Moreover, the dimension of the transversal direction of the housing 1 is several mm, for example. Further, the interval between the plurality of contacts 2, that is, the pitch is, for example, a comma number mm. In the present embodiment, the plurality of contacts 2 are arranged at an equal pitch, but may be arranged at an irregular pitch.

  The mounting bracket 5 includes a mounting member 50 that is mounted on the housing 1 of the connector 101. The attachment member 50 has a first attachment piece 51 and a second attachment piece 52. The first attachment piece 51 covers at least a part of the inner side surface S1 (see FIG. 15A) of the peripheral wall 12. The 2nd attachment piece 52 is connected with the 1st attachment piece 51, and covers at least one part of the connection surface S3 (refer FIG. 15A) which connects the outer side surface S2 (refer FIG. 15A) of the surrounding wall 12, and inner surface S1. Moreover, the attachment member 50 does not have the site | part located on the opposite side of the 1st attachment piece 51 on both sides of the surrounding wall 12 (refer FIG. 15A).

  That is, since the mounting bracket 5 of the present embodiment does not have a portion located on the opposite side of the first mounting piece 51 with the peripheral wall 12 interposed therebetween, the volume ratio of the mounting bracket 5 to the housing 1 can be reduced. it can.

(2) Details Hereinafter, the configuration of the connector 101 of the present embodiment will be described in detail. In the following, the longitudinal direction of the housing 1, 1 </ b> A is the left-right direction (first direction), the lateral direction of the housing 1, 1 </ b> A is the vertical direction (second direction), and the thickness direction of the housing 1, 1 </ b> A Direction). 1 to 31 show arrows indicating these directions (up, down, left, right, front, back), but these arrows are described only for the purpose of assisting the explanation. It is not too much, and it is not accompanied by an entity Further, the definition of the direction is not intended to limit the usage form of the connector 101 and the other connector 102 of the present embodiment.

(2.1) Overall Configuration First, the overall configuration of the connector 101 of this embodiment will be described in detail. The connector 101 of the present embodiment is a socket (female connector), and includes a housing 1, a plurality of contacts 2, and a pair of mounting brackets 5. The mounting bracket 5 will be described in detail in “(2.2) Mounting bracket”.

  The housing 1 is a flat rectangular parallelepiped shape that is long in the first direction (left-right direction), and is a resin molded body having insulating properties. In the present embodiment, the housing 1 is an insert molded product having the pair of mounting brackets 5 as an insert product. The housing 1 has a bottom wall 11, a peripheral wall 12, and a base portion 16. The bottom wall 11 has a plate shape that is long in the first direction (left-right direction), and constitutes the bottom of the housing 1. The peripheral wall 12 protrudes forward from the periphery of the bottom wall 11 and has a rectangular frame shape in plan view. That is, the peripheral wall 12 is configured to surround the bottom wall 11. Here, “plan view” means viewing from the third direction (front-rear direction).

  Specifically, the peripheral wall 12 includes 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 along the first direction in the peripheral wall 12. In each of the pair of first peripheral walls 121, a plurality of contacts 2 are stored in a plurality of storage portions 17 described later, whereby the plurality of contacts 2 are held in a state aligned in one direction (left-right direction). . That is, the peripheral wall 12 is provided with a plurality of contacts 2. In the present embodiment, each of the pair of first peripheral walls 121 holds four contacts 2.

  The base portion 16 has a rectangular parallelepiped shape that is long in the first direction (left-right direction), and protrudes forward from the center of the bottom wall 11. A portion surrounded by the bottom wall 11, the peripheral wall 12, and the base portion 16 constitutes a fitting recess 13 into which the other connector 102 is fitted. Specifically, in the fitting recess 13, a pair of first peripheral walls 121 </ b> A (described later) of the other connector 102 and a pair of second peripheral walls 122 </ b> A (described later) of the other connector 102 are fitted. As a result, the other connector 102 is connected to the connector 101.

  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 plated with gold. The contact 2 has a spring piece 24, a rising piece 25, a falling piece 26, and a terminal piece 27, which are integrally formed (see FIG. 5B).

  The spring piece 24 has a tip curved in a horseshoe shape and is configured to be elastically deformed in the second direction (vertical direction). That is, the spring piece 24 is pushed by the corresponding contact 2 </ b> A in a state where a plurality of other connector side contacts 2 </ b> A (hereinafter, in principle, referred to as “contact 2 </ b> A”) of the other connector 102 are inserted into the fitting recess 13. Thereby, the spring piece 24 is comprised so that the elastic force of the direction which goes to corresponding contact 2A may be generate | occur | produced.

  The rising piece 25 has a plate shape. The first end (rear end) of the rising piece 25 is integral with the spring piece 24. The rising piece 25 is configured to contact the corresponding contact 2 </ b> A in a state where the plurality of contacts 2 </ b> A of the other connector 102 are inserted into the fitting recess 13. The rising piece 25 is integral with a protrusion 251 protruding toward the spring piece 24. The protrusions 251 are aligned with the protrusions 221 of the corresponding contacts 2A in the third direction (front-rear direction) in a state where the plurality of contacts 2A of the other connector 102 are inserted into the fitting recesses 13 and forward of the protrusions 221. Located (see FIG. 14). That is, the protrusion 251 constitutes a lock mechanism by being hooked on the protrusion 221 of the corresponding contact 2A.

  The falling piece 26 is plate-shaped. The first end (front end) of the falling piece 26 is curved in an inverted U shape and is integrated with the second end (front end) of the rising piece 25.

  The terminal piece 27 is plate-shaped. The terminal piece 27 is integral with the second end (rear end) of the falling piece 26. The tip of the terminal piece 27 is exposed from the housing 1 at one end side (rear side) in the third direction. One surface (rear surface) of the terminal piece 27 becomes a bonding surface bonded to the substrate 7 by soldering, for example.

  The plurality of contacts 2 are roughly classified into a signal terminal 3 for signal transmission and a power terminal 4 electrically connected to a power source. In the present embodiment, among the eight contacts 2, there are four signal terminals 3 and four power supply terminals 4. In the present embodiment, the two signal terminals 3 and the two power supply terminals 4 are provided in each of the pair of first peripheral walls 121 in a state of being arranged in the arrangement direction (left-right direction). In each of the pair of first peripheral walls 121, the two signal terminals 3 are provided so as to be sandwiched between the two power supply terminals 4.

  In the present embodiment, the power supply terminal 4 has a shape in which three signal terminals 3 are arranged in one direction (left-right direction) and integrated. That is, in the present embodiment, the width dimension of the power supply terminal 4 (the dimension in the first direction (left-right direction)) is made larger than the width dimension of the signal terminal 3. Thereby, the impedance of the power terminal 4 is made smaller than the impedance of the signal terminal 3, and the rated current of the power terminal 4 is made larger than the rated current of the signal terminal 3. In the power supply terminal 4, the three spring pieces 24 are integrated with the first end (rear end) of the rising piece 25 with an interval in the first direction (left-right direction). Further, the terminal piece 27 of the power supply terminal 4 is integral with two projecting pieces 271 that project outward from one end in the second direction (vertical direction). For this reason, when the terminal piece 27 of the power supply terminal 4 is joined to the substrate 7 by, for example, soldering, the solder easily spreads in the region between the two protruding pieces 271 and the fillet is easily formed. Therefore, in this configuration, the power supply terminal 4 can be more firmly bonded to the substrate 7.

  In the present embodiment, the cross-sectional shape of the signal terminal 3 is the same as the cross-sectional shape of the power supply terminal 4 when viewed from the first direction (left-right direction). Here, “identical” is an expression including “substantially identical”. Therefore, it is an error within an allowable range that the cross-sectional shapes of the signal terminal 3 and the power supply terminal 4 are slightly different from each other due to manufacturing errors or variations.

  The housing 1 has a plurality of (eight in this case) storage portions 17 corresponding to the plurality of contacts 2 on a one-to-one basis. The plurality of storage portions 17 respectively penetrate the bottom wall 11 in the thickness direction (front-rear direction). Each of the plurality of contacts 2 is housed in the housing portion 17 by being pushed into the housing portion 17 from behind.

  The plurality of storage portions 17 are divided into two equal parts on both sides in the second direction (vertical direction) across the base portion 16. The plurality of storage portions 17 on both sides of the base portion 16 in the second direction are all provided side by side at substantially equal intervals along the first direction (left-right direction). Here, out of the four storage portions 17 on the first side (upper side) in the second direction of the base portion 16, the two storage portions 17 on both sides in the first direction (left-right direction) are respectively provided as contacts 2. The power terminal 4 is accommodated. In addition, among the four storage portions 17 on the second side (lower side) of the base portion 16 in the second direction, the power storage terminals 4 are also provided as contacts 2 in the two storage portions 17 on both sides in the first direction. It is stored. In the remaining four storage portions 17, signal terminals 3 are stored as contacts 2, respectively.

  Each of the plurality of contacts 2 is partially exposed to the fitting recess 13 in a state of being accommodated in the accommodating portion 17. Specifically, a part of each spring piece 24 of the plurality of contacts 2 is exposed to the fitting recess 13 from the inside of the base 16. Further, a part of the rising piece 25 of each of the plurality of contacts 2 is exposed to the fitting recess 13 from the inside of the first peripheral wall 121. Therefore, when the other connector 102 is connected to the connector 101, the part exposed to the fitting recess 13 of each of the plurality of contacts 2 comes into contact with the corresponding contact 2 </ b> A of the other connector 102. Thereby, the plurality of contacts 2 of the connector 101 are electrically connected to the plurality of contacts 2A of the other connector 102, respectively.

The two thick portions 18 both cover the boundary between the bottom wall 11 and the first mounting piece 51. That is, the thick portion 18 covers the boundary between the bottom wall 11 and a portion of the attachment member 50 that passes through the bottom wall 11 and is exposed to the inside of the peripheral wall 12 (first attachment piece 51).

  The housing 1 has a plurality of (here, six) protruding walls 19 (see FIGS. 1 and 3). Each of the six projecting walls 19 has a rectangular plate shape. Of the six projecting walls 19, four projecting walls 19 project from the one end (front end) in the third direction of the first peripheral wall 121 in the direction (forward) along the third direction. Further, the remaining two projecting walls 19 both project from the one end (front end) in the third direction of the second peripheral wall 122 in the direction (forward direction) along the third direction. In other words, the protruding wall 19 protrudes from the connecting surface S3 of the peripheral wall 12 in the third direction (front-rear direction). The six projecting walls 19 face the second ends of the corresponding second mounting pieces 52. Specifically, on the first side (upper side) in the second direction, the two protruding walls 19 face the second ends (upper ends) of the two second mounting pieces 52, respectively. Further, on the second side (lower side) in the second direction, the two protruding walls 19 face the second ends (lower ends) of the two second mounting pieces 52, respectively. Further, on the first side (left side) in the first direction, the projecting wall 19 faces the second end (left end) of the second mounting piece 52. Further, the projecting wall 19 faces the second end (right end) of the second mounting piece 52 on the second side (right side) in the first direction. Thus, the protruding wall 19 faces one end of the second mounting piece 52 on the outer surface S2 side.

  In this embodiment, the mounting bracket 5 on the first side (left side) in the first direction is connected to the pair of upper and lower power supply terminals 4 via the conductors of the substrate 7 in a state where the joint portion 511 is joined to the substrate 7. Electrical connection is possible. Similarly, the mounting bracket 5 on the second side (right side) in the first direction is electrically connected to the pair of upper and lower power supply terminals 4 via the conductor of the substrate 7 in a state where the joint portion 511 is joined to the substrate 7. It is possible to connect to. That is, some contacts 2 (power supply terminals 4) of the plurality of contacts 2 are configured to be electrically connected to the same potential as the mounting bracket 5.

(3) Other Connector Hereinafter, another connector 102 corresponding to the connector 101 of the present embodiment will be described with reference to FIGS.

(3.1) Overall Configuration First, the overall configuration of the other connector 102 of this embodiment will be described in detail. The connection terminal 6 will be described in detail in “(3.2) Connection terminal”. The other connector 102 of the present embodiment is a header (male connector), and as shown in FIGS. 7 to 12C, the other connector side housing 1A (hereinafter, in principle, referred to as “housing 1A”) and a plurality (here, , 8) contacts 2A. The other connector 102 of this embodiment includes two pairs of other connector side mounting brackets 5A (hereinafter, in principle, referred to as “mounting brackets 5A”) and a pair of connection terminals 6. The connection terminal 6 will be described in detail in “(3.2) Connection terminal”.

  The housing 1A is a flat rectangular parallelepiped shape that is long in the first direction (left-right direction), and is a resin molded body having an insulating property. The housing 1A has a bottom wall 11A and a peripheral wall 12A. The bottom wall 11A has a plate shape that is long in the first direction, and forms the bottom of the housing 1A. The peripheral wall 12A is integral with the bottom wall 11A. The peripheral wall 12A protrudes forward from the periphery of the bottom wall 11A so as to surround one surface (front surface) of the bottom wall 11A, and has a rectangular frame shape in plan view. That is, the peripheral wall 12A is configured to surround the bottom wall 11A. Here, “plan view” means viewing from the third direction (front-rear direction).

  Specifically, the peripheral wall 12A includes a pair of first peripheral walls 121A and a pair of second peripheral walls 122A. The pair of first peripheral walls 121A is a pair of walls that are long in the first direction (left-right direction) of the peripheral walls 12A. The pair of second peripheral walls 122A is a pair of walls that are long in the second direction (vertical direction) of the peripheral wall 12A. A portion surrounded by the bottom wall 11A and the peripheral wall 12A constitutes a fitting recess 13A into which the connector 101 is fitted. Specifically, the base 16 of the connector 101 is fitted into the fitting recess 13A.

  In the present embodiment, the housing 1A is an insert molded product having a plurality of contacts 2A and two pairs of mounting brackets 5A as insert products. In the present embodiment, the plurality of contacts 2A are provided on each of the pair of first peripheral walls 121A. Specifically, each of the pair of first peripheral walls 121A holds four contacts 2A. In the present embodiment, the pair of connection terminals 6 are held in the housing 1A by being partially pushed into the pair of second peripheral walls 122A.

  The contact 2A is a metal molded body made of a metal material such as a copper alloy. The contact 2A is plated with gold. The contact 2A may not be plated with gold. The contact 2 </ b> A has a contact piece 21, a drooping piece 22, and a terminal piece 23, which are integrally formed (see FIG. 11B). The contact piece 21 is plate-shaped. The contact piece 21 is provided on the surface of the peripheral wall 12A facing the fitting recess 13A. The contact piece 21 is configured to come into contact with the corresponding contact 2 in a state where the base portion 16 of the connector 101 is inserted into the fitting recess 13A.

  The contact piece 21 is provided with a recess 211 that is recessed in a direction away from the fitting recess 13A. The recess 211 is configured such that a part of the corresponding contact 2 is fitted in a state where the base portion 16 of the connector 101 is inserted into the fitting recess 13A. That is, the recess 211 of the contact piece 21 and the corresponding contact 2 constitute a lock mechanism that can release the connection state between the connector 101 and the other connector 102 by applying a force greater than a predetermined force.

  The hanging piece 22 has a plate shape. The drooping piece 22 is provided along the outer surface of the first peripheral wall 121A (the upper surface is the upper first peripheral wall 121A and the lower surface is the lower first peripheral wall 121A). One end (front end) of the drooping piece 22 is curved in an inverted U shape and is integrated with the first end (front end) of the contact piece 21.

  The drooping piece 22 is integrated with a protrusion 221 that projects along the thickness direction (vertical direction) of the drooping piece 22. The protrusion 221 is aligned with the protrusion 251 of the corresponding contact 2 in the third direction (front-rear direction) in a state where the base portion 16 of the connector 101 is inserted into the fitting recess 13 </ b> A, and is positioned behind the protrusion 251. (See FIG. 14). Therefore, unless the connector 101 is pulled out of the fitting recess 13A with a predetermined force or more, the connection state between the connector 101 and the other connector 102 is not released by the protrusion 251 of the contact 2 being caught by the protrusion 221 of the contact 2A. . That is, the protrusion 221 of the contact 2A and the protrusion 251 of the contact 2 constitute a lock mechanism that can release the connection state between the connector 101 and the other connector 102 by applying a force of a predetermined level or more.

  The terminal piece 23 is plate-shaped. The first end of the terminal piece 23 is integral with the second end (rear end) of the contact piece 21. Further, the second end of the terminal piece 23 is exposed from the housing 1A on one end side (rear side) in the third direction. One surface (rear surface) of the terminal piece 23 becomes a bonding surface bonded to the substrate 7 by soldering, for example.

  Similar to the connector 101, the plurality of contacts 2A are roughly divided into a signal terminal 3A and a power supply terminal 4A. In the present embodiment, like the connector 101, among the eight contacts 2A, there are four signal terminals 3A and four power terminals 4A. In the present embodiment, two signal terminals 3A and two power supply terminals 4A are provided on each of the pair of first peripheral walls 121A in a state of being arranged in the arrangement direction (left-right direction). In each of the pair of first peripheral walls 121A, the two signal terminals 3A are provided so as to be sandwiched between the two power supply terminals 4A.

  In the present embodiment, the power supply terminal 4A has a shape in which the three signal terminals 3A are arranged in one direction (left-right direction) and are integrated, like the power supply terminal 4 of the connector 101. That is, in the present embodiment, the width dimension of the power supply terminal 4A (the dimension in the first direction (left-right direction)) is made larger than the width dimension of the signal terminal 3A. Thereby, the impedance of the power terminal 4A is made smaller than the impedance of the signal terminal 3A, and the rated current of the power terminal 4A is made larger than the rated current of the signal terminal 3A. The contact piece 21 of the power terminal 4A is provided with three recesses 211. Further, the terminal piece 23 of the power supply terminal 4A is integrated with two projecting pieces 231 projecting outward from the second end in the second direction (vertical direction). For this reason, when the terminal piece 23 of the power supply terminal 4A is joined to the substrate 7 by, for example, soldering, the solder easily spreads in the region between the two protruding pieces 231 and the fillet is easily formed. Therefore, in this configuration, the power supply terminal 4 </ b> A can be more firmly bonded to the substrate 7.

  In the present embodiment, the cross-sectional shape of the signal terminal 3A is the same as the cross-sectional shape of the power supply terminal 4A when viewed from the first direction (left-right direction). Here, “identical” is an expression including “substantially identical”. Therefore, it is an error within an allowable range that the cross-sectional shapes of the signal terminal 3A and the power supply terminal 4A are slightly different from each other due to manufacturing errors or variations.

  The mounting bracket 5A is a metal molded body made of a metal material such as a copper alloy, for example, and includes a plate-like first piece 501 and a plate-like second piece 502 that is integral with the first piece 501. (See FIG. 11A). The mounting bracket 5A as a whole is L-shaped in plan view. Here, “plan view” means viewing from the first direction (left-right direction).

  A pair of mounting brackets 5A is provided on each of the pair of second peripheral walls 122A (see FIGS. 7 and 8). Specifically, the mounting bracket 5A is provided such that the first piece 501 is embedded in the second peripheral wall 122A. That is, the mounting bracket 5A is provided on the second peripheral wall 122A on which the connection terminal 6 is provided among the pair of second peripheral walls 122A. Specifically, of the pair of second peripheral walls 122A, the second peripheral wall 122A provided with the connection terminals 6 is an insert-molded product using the mounting bracket 5A as an insert product. The mounting bracket 5A is used to improve the strength of the second peripheral wall 122A (that is, the housing 1A).

  The second piece 502 is exposed from the housing 1A, and the rear surface thereof is substantially flush with the rear surface of the contact 2A. In each of the pair of first peripheral walls 121A, the two second pieces 502 are provided in the housing 1A in a state of being aligned with the terminal pieces 23 of the plurality of contacts 2A in the arrangement direction (left-right direction). Therefore, the second piece 502 can be bonded to the substrate 7 like the plurality of contacts 2A. Then, by joining the second piece 502 to the substrate 7 by soldering, the stress applied to the second piece 502 (that is, the mounting bracket 5A) can be transmitted to the substrate 7, and the substrate 7 can also receive the stress. become. For this reason, the strength of the mounting bracket 5A can be improved, and as a result, the strength of the housing 1A can be improved.

(3.2) Connection terminal Next, the connection terminal 6 in the other connector 102 of this embodiment is demonstrated in detail using FIG. 12A-FIG. 12C. In the present embodiment, the connection terminal 6 is provided on each of the pair of second peripheral walls 122A. In the following description, as a general rule, the connection terminal 6 attached to the second peripheral wall 122A on the first side (left side) in the first direction will be described as an example, but the second peripheral wall on the second side (right side) in the first direction. The connection terminal 6 attached to 122A has the same configuration.

  The connection terminal 6 is a metal molded body made of a metal material such as a copper alloy and has conductivity. Further, the connection terminal 6 is plated with gold. The connection terminal 6 may not be plated with gold. The connection terminal 6 includes a main piece 61, a facing piece 62, and a connecting piece 63. The main piece 61 has a rectangular plate shape that is long along the second direction (vertical direction). The main piece 61 is held by the housing 1A by being pushed into the groove 14 (see FIG. 8) of the second peripheral wall 122A from the rear. “Pushing” as used herein is a concept including pushing in by applying a certain force or more, that is, press-fitting.

  The groove 14 is provided in each of the pair of second peripheral walls 122A. The groove 14 is provided so as to penetrate the second peripheral wall 122A in the third direction (front-rear direction). Specifically, the groove 14 of the second peripheral wall 122A on the first side (left side) in the first direction opens a part of the front surface, a part of the rear surface, and a part of the left side surface of the second peripheral wall 122A. Is provided. Further, the groove 14 of the second peripheral wall 122A on the second side (right side) in the first direction is provided so as to open a part of the front surface, a part of the rear surface, and a part of the right side surface of the second peripheral wall 122A. ing. In the present embodiment, the dimension in the longitudinal direction (vertical direction) of the groove 14 is slightly smaller than the dimension in the longitudinal direction (vertical direction) of the main piece 61 of the connection terminal 6. Therefore, the main piece 61 of the connection terminal 6 is held in the housing 1A in a plastically deformed state by being pushed into the groove 14 from the rear. That is, the connection terminal 6 is configured such that a part (main piece 61) is held by the housing 1A.

  A first end (front end) in the short direction of the main piece 61 is integral with a first end of the connecting piece 63. In the present embodiment, the first ends of the two connecting pieces 63 are integrated with the first ends of the main pieces 61 in the short direction at intervals in the longitudinal direction (vertical direction) of the main pieces 61. The second ends of the two connecting pieces 63 are integral with the first ends (front ends) of the corresponding opposing pieces 62 in the longitudinal direction. That is, the connection terminal 6 has a plurality (here, two) of opposing pieces 62. The first ends of the plurality of facing pieces 62 are integral with the corresponding plurality (here, two) of connecting pieces 63.

  In the connection terminal 6, neither the opposing piece 62 nor the connecting piece 63 is held by the housing 1A. In the present embodiment, in the state where the main piece 61 is held by the housing 1A (second peripheral wall 122A), gaps are respectively generated between the facing piece 62 and the connecting piece 63 and the housing 1A. For this reason, in this embodiment, the opposing piece 62 and the connecting piece 63 are easily deformed elastically without being obstructed by the housing 1A.

  The connecting piece 63 connects the end portions (here, the front ends) of the main piece 61 and the opposing piece 62. Specifically, the upper connecting piece 63 connects the first end (front end) in the short direction of the main piece 61 and the first end (front end) in the longitudinal direction of the upper facing piece 62. Further, the lower connecting piece 63 connects the first end (front end) in the short direction of the main piece 61 and the first end (front end) in the longitudinal direction of the lower facing piece 62. Further, the connecting piece 63 is curved in an inverted U shape in plan view. Here, “plan view” means viewing from the second direction (vertical direction).

  At the first end (front end) of the main piece 61 in the short direction, avoiding portions 610 are provided at both corners in the longitudinal direction (vertical direction) of the main piece 61. The avoiding portion 610 is recessed in a direction (backward direction) along the third direction (front-rear direction). This direction corresponds to a direction opposite to the direction in which the connection terminal 6 is pushed into the second peripheral wall 122A. That is, the avoiding portion 610 is provided at a corner portion of one end (here, the front end) connected to the connecting piece 63 in the main piece 61, and the direction opposite to the direction in which the connecting terminal 6 is pushed into the second peripheral wall 122A (that is, , Backwards).

  In the connection terminal 6 on the first side (left side) in the first direction, the avoiding portion 610 on the first side (upper side) in the second direction is provided so as to open front, upper, and left sides. Further, in the connection terminal 6 on the first side (left side) in the first direction, the avoiding portion 610 on the second side (lower side) in the second direction is provided so as to open the front, the lower side, and the left side. Yes. Similarly, in the connection terminal 6 on the second side (right side) in the first direction, the avoiding portion 610 on the first side (upper side) in the second direction is provided so as to open frontward, upward, and rightward. Yes. Further, in the connection terminal 6 on the second side (right side) in the first direction, the avoiding portion 610 on the second side (lower side) in the second direction is provided so as to open the front, the lower side, and the right side. Yes. Further, the avoiding portion 610 is provided so that the opening surface viewed from the third direction (front-rear direction) expands from the rear toward the front.

  As for the length of the main piece 61 in the longitudinal direction (vertical direction), the dimension on the second end (rear end) side in the short side direction is larger than the dimension on the first end (front end) side in the short side direction. Yes. Further, the second end (rear end) in the short direction of the main piece 61 is exposed from the housing 1A at one end side (rear side) in the third direction of the housing 1A. One surface (rear surface) of the second end in the short direction of the main piece 61 is substantially flush with one surface (rear surface) of the plurality of contacts 2A, and becomes a bonding surface bonded to the substrate 7 by soldering, for example. That is, the connection terminal 6 further includes a joint portion 611 that is joined to the substrate 7. And the junction part 611 is provided in the 2nd end (rear end) of the transversal direction of the main piece 61, ie, the end of the bottom wall 11 side.

  Two concave portions 612 are provided at the second end (rear end) in the short direction of the main piece 61. Each of the two recesses 612 is recessed in a direction along the thickness direction of the housing 1A (here, forward). This direction corresponds to a direction in which the connection terminal 6 is pushed into the second peripheral wall 122A. Moreover, the two recessed parts 612 are connected, and the site | part to which the two recessed parts 612 are connected is also dented in the direction (front direction) along a 3rd direction. That is, the recess 612 is provided at the second end (rear end) in the short direction of the main piece 61, that is, at one end on the bottom wall 11A side, and in a direction (forward facing) to push the connection terminal 6 into the second peripheral wall 122A. It is depressed.

  The facing piece 62 has a rectangular plate shape that is long in the third direction (front-rear direction). The facing piece 62 faces the main piece 61 with a space in the first direction (left-right direction) and is exposed from the second peripheral wall 122A. Specifically, the opposing piece 62 of the connection terminal 6 on the first side (left side) in the first direction is exposed from the left surface of the second peripheral wall 122A. Further, the opposing piece 62 of the connection terminal 6 on the second side (right side) in the first direction is exposed from the right surface of the second peripheral wall 122A.

  A gap is provided between the facing piece 62 and the main piece 61. Moreover, the opposing piece 62 and the connecting piece 63 among the connection terminals 6 are not held by the housing 1A. For this reason, the opposing piece 62 and the connecting piece 63 can be elastically deformed. In particular, the opposing piece 62 can be elastically deformed in the first direction (left-right direction). That is, in the connection terminal 6, the portions (opposing piece 62 and connecting piece 63) that are not held by the housing 1 </ b> A can be elastically deformed.

  The opposing piece 62 is provided with a protrusion 621 that protrudes in a direction along the first direction (left-right direction). Specifically, a protruding portion 621 protruding leftward is provided on the facing piece 62 of the connection terminal 6 on the first side (left side) in the first direction. Further, a protrusion 621 that protrudes rightward is provided on the facing piece 62 of the connection terminal 6 on the second side (right side) in the first direction. That is, the opposing piece 62 has a protrusion 621 that protrudes in a direction along the direction in which the pair of second peripheral walls 122A are arranged.

  In the present embodiment, the protrusion 621 extends from the second end (rear end) in the longitudinal direction of the facing piece 62 along the third direction (front-rear direction). That is, the protrusion 621 extends along a direction orthogonal to the bottom wall 11A of the housing 1A. Further, one end (front end) of the protrusion 621 on the side of the connecting piece 63 has a taper in which the amount of protrusion from the facing piece 62 becomes smaller as the connecting piece 63 is approached. Due to this taper, when the other connector 102 is connected to the connector 101, the protrusion 621 is hardly caught on the mounting bracket 5 of the connector 101.

  In the present embodiment, the connection terminal 6 on the first side (left side) in the first direction is connected to the pair of upper and lower power supply terminals 4 </ b> A via the conductor of the substrate 7 in a state where the bonding portion 611 is bonded to the substrate 7. Electrical connection is possible. Similarly, the connection terminal 6 on the second side (right side) in the first direction is electrically connected to the pair of upper and lower power supply terminals 4 </ b> A via the conductors of the substrate 7 in a state where the joint portion 611 is joined to the substrate 7. It is possible to connect to. That is, some of the contacts 2A (power supply terminal 4A) among the plurality of contacts 2A are configured to be electrically connected to the same potential as the connection terminal 6.

(4) Connection System The connector 101 is mounted on a substrate 7 (hereinafter also referred to as “first substrate 71”) built in an electronic device such as a smartphone (see FIG. 13). The other connector 102 corresponding to the connector 101 is mounted on another board 7 (hereinafter also referred to as “second board 72”) that is also built in the electronic device (see FIG. 13).

  Then, as shown in FIGS. 13 and 14, by connecting the connector 101 to the other connector 102, an electrical connection is established between the first conductor of the first substrate 71 and the second conductor of the second substrate 72. Connected to. Specifically, the plurality of contacts 2 of the connector 101 are electrically connected to the plurality of contacts 2A of the other connector 102, whereby the connector 101 is connected to the other connector 102. At this time, a plurality of (here, four) signal terminals 3 of the connector 101 are electrically connected to a plurality of (here, four) signal terminals 3A corresponding to the other connector 102, respectively. In addition, a plurality of (here, four) power supply terminals 4 of the connector 101 are electrically connected to a plurality of (here, four) power supply terminals 4A corresponding to the other connectors 102, respectively. That is, in this embodiment, the connection system 100 is configured by the connector 101 and the other connector 102. In other words, the connection system 100 includes a connector 101 and another connector 102. In FIG. 13 and FIG. 14, the other connector 102 is illustrated in a state where the front and rear are reversed. The same applies to FIGS. 15A and 15B described later.

  Here, when the connector 101 is connected to the other connector 102, the opposing piece 62 of the connection terminal 6 is connected to the first mounting piece 51 and the second mounting piece 52 of the mounting bracket 5 as shown in FIGS. 15A and 15B. It is pushed in a direction along one direction (left-right direction). For this reason, the connection terminal 6 contacts the mounting bracket 5 in a state of being elastically deformed in the direction along the first direction (left-right direction). Specifically, in the connection terminal 6 on the first side (left side) in the first direction, the two opposing pieces 62 come into contact with the first attachment piece 51 of the attachment fitting 5 while being elastically deformed rightward. Further, in the connection terminal 6 on the second side (right side) in the first direction, the two opposing pieces 62 come into contact with the first attachment piece 51 of the attachment fitting 5 while being elastically deformed leftward. That is, in a state where the connector 101 is connected to the other connector 102, the connection terminal 6 gives the mounting bracket 5 an elastic force for returning to the original state.

  In a state where the connector 101 is connected to the other connector 102, the mounting bracket 5 comes into contact with the connection terminal 6, whereby the mounting bracket 5 is electrically connected to the connection terminal 6. Therefore, the first conductor that is electrically connected to the mounting bracket 5 among the first conductors included in the first substrate 71 and the connection terminal 6 among the second conductors included in the second substrate 72 are electrically connected. The second conductor is electrically connected. In the present embodiment, the first conductor that is electrically connected to the power supply terminal 4 of the connector 101 and the second conductor that is electrically connected to the power supply terminal 4A of the other connector 102 via the mounting bracket 5 and the connection terminal 6. The conductor is electrically connected.

(5) Advantages In describing the advantages of the mounting bracket 5 of the present embodiment, first, a comparative example of the mounting bracket 5 of the present embodiment will be given. The basic structure of the mounting bracket of the comparative example is the same as that of the mounting bracket 5 of the present embodiment, but the portion where the mounting member is located on the opposite side of the first mounting piece with the peripheral wall 12 interposed therebetween (hereinafter “opposite” Side part)). The mounting bracket of the comparative example is mounted on the peripheral wall 12 similarly to the mounting bracket 5 of the present embodiment. Here, in the mounting bracket of the comparative example, since the mounting member has the opposite side portion, compared with the mounting bracket 5 of the present embodiment, the volume is large by the amount of the opposite side portion, and the housing The volume ratio to 1 is also large.

  On the other hand, in the mounting bracket 5 of the present embodiment, since the mounting member 50 does not have the opposite side portion, the volume ratio of the mounting bracket 5 to the housing 1 can be reduced. For this reason, the mounting bracket 5 of the present embodiment can reduce the size of the connector 101 compared to the case where the mounting member 50 has the opposite side portion. That is, compared with the case where the attachment member 50 has an opposite side portion that covers the outer side surface S2 of the peripheral wall 12, the dimension in the thickness direction of the peripheral wall 12 can be reduced. As a result, the connector 101 can be downsized. You can plan. Further, when the size of the connector 101 is defined to be a predetermined size, the strength of the housing 1 can be improved as compared with the case where the attachment member 50 has the opposite side portion. That is, since the attachment member 50 does not have the opposite side portion, the thickness direction of the peripheral wall 12 (the second direction (vertical direction) of the first peripheral wall 121 and the second peripheral wall 122 is the same as the opposite side portion). Since the dimension in one direction (left-right direction) can be increased, the strength of the housing 1 can be improved.

(6) Modifications Modifications of this embodiment will be listed below. Since the basic configuration of the modified example described below is common to the other connector 102 of the present embodiment, the description of the common points is omitted. In addition, any of the modifications described below can be used in the connection system 100 in place of the other connector 102 of the present embodiment. The modifications described below can be applied in appropriate combinations. For example, the first modification and the second modification can be combined with any of the third to seventh modifications.

(6.1) First Modification The other connector 102 of the first modification does not include the mounting bracket 5A as shown in FIGS. In this modification, only the connection terminal 6 is attached to each of the pair of second peripheral walls 122A, and the pair of attachment fittings 5A is not attached. In this configuration, since it is not necessary to provide a space for attaching the mounting bracket 5A to the housing 1A, the dimension of the housing 1A (particularly, the dimension in the longitudinal direction of the housing 1A) can be reduced. That is, in this configuration, the other connector 102 can be reduced in size.

(Summary)
As described above, the mounting bracket (5) of the first aspect includes the mounting member (50). The attachment member (50) is attached to the housing (1) of the connector (101) having a plurality of contacts (2). The housing (1) has a bottom wall (11) and a peripheral wall (12) surrounding the bottom wall (11). The attachment member (50) has a first attachment piece (51) and a second attachment piece (52). The first mounting piece (51) covers at least a part of the inner surface (S1) of the peripheral wall (12). The second mounting piece (52) is connected to the first mounting piece (51), and at least part of the connecting surface (S3) connecting the outer surface (S2) and the inner surface (S1) of the peripheral wall (12). cover. The attachment member (50) does not have a part (opposite part) located on the opposite side of the first attachment piece (51) across the peripheral wall (12).

  According to this configuration, since the opposite portion is not provided, the volume ratio of the mounting bracket (5) to the housing (1) can be reduced.

  In the mounting bracket (5) of the second aspect, in the first aspect, the first mounting piece (51) penetrates the bottom wall (11) in the thickness direction of the bottom wall (11). The attachment member (50) further includes a third attachment piece (53). The third attachment piece (53) extends along the bottom wall (11) from one end of the first attachment piece (51) on the bottom wall (11) side.

  According to this configuration, even when another connector (102) is connected to the connector (101), even if stress in the direction along the thickness direction of the bottom wall (11) is applied to the bottom wall (11), this stress is applied. Can be received by the third mounting piece (53). For this reason, according to this structure, the intensity | strength of a bottom wall (11), ie, a housing (1), can be improved compared with the case where it does not have the 3rd attachment piece (53). However, this configuration is not essential, and the attachment member (50) may not have the third attachment piece (53). Furthermore, the 1st attachment piece (51) does not need to penetrate the bottom wall (11).

  In the mounting bracket (5) of the third aspect, in the second aspect, the third mounting piece (53) has a recess (531). The recess (531) is recessed along the bottom wall (11) in plan view.

  According to this structure, when joining the 3rd attachment piece (53) to a board | substrate (7) by soldering, a solder tends to spread to a recess (531) and a fillet is easy to be formed. For this reason, according to this structure, when joining the 3rd attachment piece (53) to a board | substrate (7), a 3rd attachment piece (53) can be joined more firmly with respect to a board | substrate (7). . However, this configuration is not essential, and the third attachment piece (53) may not have the recess (531).

  In the mounting bracket (5) of the fourth aspect, in any one of the first to third aspects, the mounting member (50) is a set of the first mounting piece (51) and the second mounting piece (52). As the piece (54), a plurality of assembled pieces (54) are provided.

  According to this structure, the external force applied to the connector (101) can be received by the plurality of sets (54). For this reason, according to this structure, the intensity | strength of a housing (1) can be improved compared with the case where it has only one piece (54). However, this configuration is not essential, and the attachment member (50) may have only one assembly piece (54).

  In the mounting bracket (5) of the fifth aspect, in the fourth aspect, the mounting member (50) has two pieces (54). The two pieces (54) are respectively attached to the pair of first peripheral walls (121). The pair of first peripheral walls (121) holds the contacts (2) of the peripheral walls (12) in a state of being arranged in the arrangement direction.

  According to this configuration, the external force applied to the pair of first peripheral walls (121) can be received by the two assembled pieces (54). For this reason, according to this structure, the intensity | strength of a pair of 1st surrounding wall (121) can be improved, and the intensity | strength of a housing (1) can be improved as a result. However, this configuration is not essential, and the assembly piece (54) may be attached to a portion of the peripheral wall (12) other than the pair of first peripheral walls (121).

  In the mounting bracket (5) of the sixth aspect, in the fourth aspect, the mounting member (50) has three pieces (54). The three pieces (54) are respectively provided on the pair of first peripheral walls (121) and the second peripheral wall (122) of the peripheral walls (12). The pair of first peripheral walls (121) holds the plurality of contacts (2) in a state of being arranged in the arrangement direction. The second peripheral wall (122) connects the ends of the pair of first peripheral walls (121).

  According to this structure, the external force applied to a pair of 1st surrounding wall (121) and 2nd surrounding wall (122) can be received by three sets of pieces (54). For this reason, according to this structure, the intensity | strength of a pair of 1st surrounding wall (121) and 2nd surrounding wall (122) can be improved, and the intensity | strength of a housing (1) can be improved as a result. However, this configuration is not essential, and the assembly piece (54) may be attached to a portion of the peripheral wall (12) other than the pair of the first peripheral wall (121) and the second peripheral wall (122).

  In the attachment bracket (5) of the seventh aspect, in any one of the first to sixth aspects, the attachment member (50) further includes a joint portion (511) joined to the substrate (7). The joining portion (511) is provided at one end of the first mounting piece (51) on the bottom wall (11) side.

  According to this configuration, when the attachment member (50) is joined to the substrate (7), the portion of the first attachment piece (51) that is not joined to the substrate (7) and the second attachment piece (52) are: It is not fixed to the substrate (7). For this reason, according to this structure, compared with the case where an attachment member (50) has an other side part, the stress added to an attachment member (50) when connecting another connector (102) to a connector (101) is applied. Can be reduced.

  That is, in the configuration in which the attachment member (50) has the opposite side portion, the first attachment piece (51) and the opposite side portion sandwich the peripheral wall (12). In this configuration, when the opposite side portion is joined to the substrate (7), when the other connector (102) is connected to the connector (101), the first attachment piece (51), the second attachment piece (52), and the opposite The side part is difficult to elastically deform. Therefore, in this configuration, it is difficult to escape the external force applied to the connector (101). On the other hand, in the configuration in which the attachment member (50) does not have the opposite side portion, when the other connector (102) is connected to the connector (101), the first attachment piece (51) and the second attachment piece (52). Is easily elastically deformed. Therefore, in this configuration, the external force applied to the connector (101) can be easily released, and as a result, the stress applied to the mounting member (50) can be reduced.

  Moreover, according to this structure, compared with the case where an other side part is joined to a board | substrate (7), the residual stress of an attachment member (50) can be reduced. However, this configuration is not essential, and the attachment member (50) may not have the joint portion (511).

  The connector (101) according to the eighth aspect includes the mounting bracket (5) according to any one of the first to seventh aspects, a housing (1), and a plurality of contacts (2).

  According to this configuration, when a part of the mounting member (50) exposed from the exposed portion (111) is joined to the substrate (7) by soldering, the mounting bracket (5) is firmly fixed to the substrate (7). The strength of the mounting bracket (5) can be further improved. Further, when the mounting bracket (5) is electrically connected to the same potential as that of some contacts (2), the impedance of the mounting bracket (5) can be reduced. However, this configuration is not essential, and the housing (1) may not have the exposed portion (111).

The thick part (18) covers the boundary between the bottom wall (11) and a part of the attachment member (50) that penetrates the bottom wall (11) and is exposed to the inside of the peripheral wall (12).

  According to this configuration, when connecting the other connector (102) to the connector (101), the external force applied to the connector (101) can be received by the thick portion (18). For this reason, according to this structure, compared with the case where it does not have a thick part (18), an external force is hard to be transmitted to a bottom wall (11) and an attachment member (50), and, as a result, housing (1) Strength can be improved. However, this configuration is not essential, and the housing (1) may not have the thick portion (18).

  In the connector (101) of the eleventh aspect, in any of the eighth to tenth aspects, the housing (1) further includes a protruding wall (19). The protruding wall (19) protrudes from the connecting surface (S3) in the thickness direction of the housing (1) and faces one end on the outer surface (S2) side of the second mounting piece (52).

  According to this configuration, when an external force is applied from the outside of the housing (1) toward the end (here, the second end) located on the connecting surface (S3) of the second mounting piece (52), This external force is easily received by the protruding wall (19). For this reason, according to this structure, this external force is not easily transmitted to the second mounting piece (52), and as a result, the second mounting piece (52) is not easily deformed. However, this configuration is not essential, and the housing (1) may not have the protruding wall (19).

  The header of the twelfth aspect is a header as another connector (102) connected to the socket as the connector (101) of any of the eighth to eleventh aspects. The header has a plurality of other connector side contacts (2A) electrically connected to the plurality of contacts (2) of the socket.

  According to this structure, the header which can aim at reduction of the volume ratio with respect to the housing (1) of a mounting bracket (5) is realizable.

  By the way, the connector (101) may be connected to the other connector (102) of any one of the following first to sixteenth aspects without depending on the above-described eighth to eleventh aspects. Good. That is, if the connector (101) is configured to be connected to the other connector (102) of any one of the following first to thirteenth aspects, any of the above eighth to eleventh aspects is provided. It need not be an aspect.

  The other connector (102) of the first aspect includes a plurality of contacts (2A), a housing (1A), and a connection terminal (6). The housing (1A) holds a plurality of contacts (2A).
