Detailed Description

(embodiment mode 1)

(1) Summary of the invention

Hereinafter, the connector 101 according to embodiment 1 will be described with reference to C in fig. 1 to 6. The connector 101 of the present embodiment is mounted on a substrate 7 such as a printed wiring board or a flexible printed wiring board (see fig. 13). The connector 101 is used to electrically connect a plurality of boards 7 mounted on a mobile terminal such as a smartphone. Of course, the use of the connector 101 is not limited, and the connector 101 may be used for electronic devices other than a portable terminal such as a camera module. The connector 101 is not limited to the use for electrically connecting the plurality of substrates 7, and may be used for electrically connecting a plurality of members, such as a substrate 7 and a display, and a substrate 7 and a battery.

The connector 101 includes a housing 1, a plurality of contacts 2, and a connection terminal 6. The housing 1 holds a plurality of tabs 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 connectors 2 in a state of being aligned in the alignment direction (the 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 of the case 1 in the thickness direction is, for example, several mm or less. The dimension of the housing 1 in the longitudinal direction is, for example, ten and several mm. The dimension of the housing 1 in the width direction is, for example, several mm. The arrangement interval, i.e., the pitch of the plurality of joints 2 is, for example, several tenths of mm. In the present embodiment, the plurality of tabs 2 are arranged at equal pitches, but may be arranged at unequal pitches.

The connection terminal 6 has conductivity, and can be electrically connected to a conductive portion having conductivity of another connector 102 (described later). In addition, a part of the connection terminal 6 is held by the housing 1. Specifically, the connection terminal 6 is held by at least one second peripheral wall 122 of the pair of second peripheral walls 122. In the present embodiment, the connection terminal 6 is held by the housing 1 by being partially pressed into at least one second peripheral wall 122 of the pair of second peripheral walls 122. At least a part of the connection terminal 6 not held by the housing 1 is a part in contact with the conductive part and is elastically deformable.

That is, the connector 101 of the present embodiment includes the connection terminal 6 having conductivity in addition to the plurality of contacts 2. Therefore, when the connector 101 of the present embodiment is connected to the other connector 102, not only the plurality of contacts 2 but also the connection terminal 6 is electrically connected to the other connector 102, and as a result, reliability of electrical connection to the other connector 102 can be improved.

(2) Detailed description of the invention

The structure of the connector 101 according to the present embodiment will be described in detail below. Hereinafter, the longitudinal direction of the

housings

1 and 1A is referred to as the lateral direction (first direction), the width direction of the

housings

1 and 1A is referred to as the vertical direction (second direction), and the thickness direction of the

housings

1 and 1A is referred to as the front-rear direction (third direction). In fig. 1 to 32, arrows indicating the directions (up, down, left, right, front, and rear) are shown, but the arrows are described only for the purpose of assisting the description and do not have entities. The above-described direction is not limited to the use of the connector 101 and the other connector 102 in this embodiment and embodiment 2 described later.

(2.1) integral Structure

First, the overall configuration of the connector 101 of the present embodiment will be described in detail. As for the connection terminal 6, a detailed description is given in "(2.2) connection terminal". The connector 101 of the present embodiment is a plug (male connector), and includes a housing 1, a plurality of (here, eight) contacts 2, two pairs of mounting fittings 5, and a pair of connection terminals 6, as shown in C of fig. 1 to 6.

The housing 1 is a flat rectangular parallelepiped shape elongated in the first direction (the left-right direction), and is a resin molded body having insulation properties. The housing 1 has a bottom wall 11 and a peripheral wall 12. The bottom wall 11 is plate-shaped and long in the first direction, and constitutes a bottom of the housing 1. The peripheral wall 12 is formed integrally with the bottom wall 11. The peripheral wall 12 projects forward so as to surround one surface (front surface) of the bottom wall 11 from the peripheral edge 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, the "plan view" refers to a view 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 that are longer in the first direction (left-right direction) of the peripheral walls 12. The pair of second peripheral walls 122 is a pair of walls that are longer in the second direction (up-down direction) of the peripheral wall 12. The portion surrounded by the bottom wall 11 and the peripheral wall 12 constitutes a fitting recess 13 into which the other connector is fitted. Specifically, the step 16 (described later) of the other connector 102 is fitted into the fitting recess 13.

In the present embodiment, the housing 1 is an insert-molded article in which the plurality of connectors 2 and the two pairs of mounting fittings 5 are inserts. In the present embodiment, the plurality of joints 2 are provided on each of the first peripheral walls 121 of the pair of first peripheral walls 121. Specifically, the pair of first peripheral walls 121 hold four joints 2, respectively. In the present embodiment, the pair of connection terminals 6 are held by the housing 1 by pressing a portion of each of the pair of second peripheral walls 122.

The joint 2 is a metal molded body made of a metal material such as a copper alloy. Further, the tab 2 is plated with gold. Note that gold plating may not be applied to the contact 2. The header 2 includes a contact piece 21, a hanging piece 22, and a terminal piece 23, which are integrally formed (see B of fig. 5). The contact piece 21 has a plate shape. The contact piece 21 is provided on the facing surface of the peripheral wall 12 facing the fitting recess 13. The contact piece 21 is configured to contact the corresponding other connector-side contact 2A (described later) in a state where the step portion 16 of the other connector 102 is inserted into the fitting recess 13.

Further, the contact piece 21 is provided with a recess 211 recessed toward a direction away from the fitting recess 13. The recess 211 is configured to fit a part of the corresponding other connector-side contact 2A in a state where the step 16 of the other connector 102 is inserted into the fitting recess 13. That is, the recesses 211 of the contact pieces 21 and the corresponding other connector-side contacts 2A constitute a lock mechanism capable of releasing the connection state between the connector 101 and the other connector 102 by applying a force of a predetermined value or more.

The hanging piece 22 is plate-shaped. The hanging piece 22 is provided along an outer surface of the first peripheral wall 121 (an upper surface in the case of the upper first peripheral wall 121, and a lower surface in the case of the lower first peripheral wall 121). One end (front end) of the hanging piece 22 is bent in an inverted U shape and is integrally formed with the first end (front end) of the contact piece 21.

The hanging-down piece 22 is integrally formed with a projection 221 projecting in the thickness direction (vertical direction) of the hanging-down piece 22. The projections 221 are aligned in the third direction (front-rear direction) with projections 251 (described later) of the corresponding other connector-side contact 2A in a state where the step 16 of the other connector 102 is inserted into the fitting recess 13, and are positioned rearward of the projections 251 (see fig. 14). Therefore, when the other connector 102 is not pulled out from the fitting recess 13 with a force equal to or greater than a predetermined force, the protrusion 251 of the other connector-side contact 2A is locked to the protrusion 221 of the contact 2, and the connection state between the connector 101 and the other connector 102 is not released. That is, the projection 221 of the connector 2 and the projection 251 of the other connector-side connector 2A constitute a lock mechanism capable of releasing the connection state between the connector 101 and the other connector 102 by applying a force of a predetermined value or more.

The terminal piece 23 has a plate shape. The first end of the terminal piece 23 is formed integrally with the second end (rear end) of the contact piece 21. The second end of the terminal piece 23 is exposed from the housing 1 at one end side (rear side) in the third direction. One surface (rear surface) of the terminal piece 23 is a bonding surface to be bonded to the substrate 7 by, for example, soldering.

The plurality of contacts 2 are roughly divided into signal terminals 3 and power supply terminals 4. The signal terminal 3 is a terminal for signal transmission. The power supply terminal 4 is a terminal electrically connected to a power supply. In the present embodiment, eight contacts 2 include 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 the arrangement direction (the left-right direction) in each of the pair of first peripheral walls 121 in the first peripheral wall 121. In addition, two signal terminals 3 are provided on each of the pair of first peripheral walls 121 so as to be sandwiched between the two power supply terminals 4.

In the present embodiment, the power supply terminal 4 is formed in a shape in which three signal terminals 3 are arranged in one direction (left-right direction) and are integrally formed. That is, in the present embodiment, the width dimension (the dimension in the first direction (the left-right direction)) of the power supply terminal 4 is made larger than the width dimension of the signal terminal 3. Thus, the impedance of the power supply terminal 4 is made smaller than the impedance of the signal terminal 3, and the rated current of the power supply terminal 4 is made larger than the rated current of the signal terminal 3. In addition, three recesses 221 are provided in the hanging piece 22 of the power terminal 4. The terminal piece 23 of the power terminal 4 is integrally formed with two projecting pieces 231 projecting outward in the second direction (vertical direction) from the second end. Therefore, when the terminal piece 23 of the power terminal 4 is joined to the substrate 7 by soldering, for example, the solder easily spreads to the region between the two projecting pieces 231, and a fillet is easily formed. Therefore, in this structure, the power supply terminal 4 can be firmly bonded to the substrate 7.

In the present embodiment, the shape of the cross section of the signal terminal 3 is the same as the shape of the cross section of the power supply terminal 4 when viewed from the first direction (left-right direction). The term "identical" herein includes "substantially identical". Therefore, it is an error within an allowable range that the shapes of the cross sections of the signal terminal 3 and the power supply terminal 4 are slightly different from each other due to manufacturing errors or variations.

The attachment 5 is a metal molded body made of a metal material such as a copper alloy, and includes a plate-shaped first piece 501 and a plate-shaped second piece 502 integrally formed with the first piece 501 (see a in fig. 5 a). The mounting metal fitting 5 is L-shaped as a whole in a plan view. Here, the "plan view" refers to a view from a first direction (left-right direction).

The mounting metal fitting 5 is provided in a pair in each of the pair of second peripheral walls 122 (see fig. 1 and 2). Specifically, the mounting fitting 5 is provided such that the first plate 501 is buried in the second peripheral wall 122. That is, the mounting metal 5 is provided in the second peripheral wall 122 provided with the connection terminal 6 out of the pair of second peripheral walls 122. Specifically, the second peripheral wall 122 provided with the connection terminal 6 out of the pair of second peripheral walls 122 is an insert-molded article in which the attachment fitting 5 is an insert. The mounting fitting 5 serves to improve the strength of the second peripheral wall 122 (i.e., the housing 1).

The second piece 502 is exposed from the housing 1 with its rear surface substantially coplanar with the rear surface of the header 2. In each of the pair of first peripheral walls 121, the two second pieces 502 are provided in the housing 1 so as to be aligned with the terminal pieces 23 of the plurality of connectors 2 in the alignment direction (left-right direction). Therefore, the second sheet 502 can be bonded to the substrate 7 in the same manner as the plurality of tabs 2. Further, by joining the second sheet 502 to the substrate 7 by soldering, stress applied to the second sheet 502 (i.e., the mounting component 5) can be transmitted to the substrate 7, and the stress can be received by the substrate 7. Therefore, the strength of the attachment fitting 5 can be increased, and as a result, the strength of the housing 1 can be increased.

(2.2) connection terminal

Next, the connection terminal 6 in the connector 101 of the present embodiment will be described in detail with reference to fig. 6 a to 6C. In the present embodiment, the connection terminal 6 is provided to each of the second peripheral walls 122 of the pair of second peripheral walls 122. In the following description, the connection terminal 6 attached to the second peripheral wall 122 on the first side (left side) in the first direction is described as an example in principle, but the connection terminal 6 attached to the second peripheral wall 122 on the second side (right side) in the first direction 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, gold plating is applied to the connection terminals 6. Note that gold plating may not be applied to the connection terminals 6. The connection terminal 6 includes a main piece 61, an opposing piece 62, and a connecting piece 63. The main piece 61 has a rectangular plate shape that is long in the second direction (vertical direction). The main piece 61 is pressed into the groove 14 (see fig. 2) of the second peripheral wall 122 from the rear, and is held by the housing 1. The term "press-in" as used herein includes a concept that a force of a predetermined amount or more is applied to press-in, that is, press-in.

The groove 14 is provided in each of the pair of second peripheral walls 122. The groove 14 is provided so as to penetrate the second peripheral wall 122 in the third direction (front-rear direction). Specifically, the groove 14 of the second peripheral wall 122 on the first side (left side) in the first direction is provided so that 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 122 are opened. The groove 14 of the second peripheral wall 122 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 122. 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 pushed into the groove 14 from behind, and is held by the housing 1 in a state after plastic deformation. That is, the connection terminal 6 is partially (main piece 61) held by the housing 1.

A first end (tip) of the main piece 61 in the width direction is integrally formed with a first end of the connecting piece 63. In the present embodiment, the first ends of the two coupling pieces 63 are formed integrally with the first end of the main piece 61 in the width direction thereof at intervals in the longitudinal direction (vertical direction) of the main piece 61. Second ends of the two coupling pieces 63 are integrally formed with first ends (distal ends) of the corresponding opposing pieces 62 in the longitudinal direction, respectively. That is, the connection terminal 6 has a plurality of (here, two) opposing pieces 62. First ends of the opposing pieces 62 are integrally formed with a corresponding plurality of (here, two) connecting pieces 63.

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

The connecting piece 63 connects the ends (tip ends in this case) of the main piece 61 and the opposing piece 62 to each other. Specifically, the upper connecting piece 63 connects a first end (front end) of the main piece 61 in the width direction and a first end (front end) of the upper facing piece 62 in the longitudinal direction. The lower connecting piece 63 connects a first end (tip) of the main piece 61 in the width direction and a first end (tip) of the lower facing piece 62 in the longitudinal direction. The connecting piece 63 has an inverted U-shape in plan view. Here, the "plan view" refers to a view from the second direction (vertical direction).

Relief portions 610 are provided at both corners in the longitudinal direction (vertical direction) of the main piece 61 at a first end (front end) in the width direction of the main piece 61. The escape portion 610 is recessed toward the direction (rear) 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 122. That is, the escape portion 610 is provided at a corner portion of one end (here, the front end) of the main piece 61 connected to the connecting piece 63, and is recessed in a direction opposite to a direction in which the connection terminal 6 is pushed into the second peripheral wall 122 (i.e., rearward).

In other words, the connector 101 includes the plurality of contacts 2, the housing 1 holding the plurality of contacts 2, and the connection terminal 6. The connection terminal 6 has conductivity, and can be electrically connected to a conductive portion (in the present embodiment, a mounting metal fitting 5A described later) having conductivity of the other connector 102. The connection terminal 6 is held by the housing 1 by being partially pushed into the housing 1. At least a part of the connection terminal 6 not held by the housing 1 is a part in contact with the conductive part and is elastically deformable. The connection terminal 6 includes a main piece 61, an opposing piece 62, and a connecting piece 63. The main piece 61 is held by the housing 1. The opposing piece 62 faces the main piece 61 with a space therebetween and is exposed from the housing 1. The connecting piece 63 connects the ends of the main piece 61 and the opposing piece 62 to each other. The main piece 61 has a relief portion 610. The escape portion 610 is provided at a corner portion of one end of the main piece 61 connected to the connecting piece 63, and is recessed in a direction opposite to a direction in which the connection terminal 6 is pushed into the housing 1.

In the connection terminal 6 on the first side (left side) in the first direction, the escape portion 610 on the first side (upper side) in the second direction is provided so as to be open to the front, upper, and left. In addition, in the connection terminal 6 on the first side (left side) in the first direction, the escape portion 610 on the second side (lower side) in the second direction is provided so as to be open to the front, the lower, and the left. Similarly, in the connection terminal 6 on the second side (right side) in the first direction, the escape portion 610 on the first side (upper side) in the second direction is provided so as to be open to the front, the upper side, and the right side. In the connection terminal 6 on the second side (right side) in the first direction, the escape portion 610 on the second side (lower side) in the second direction is provided so as to be open to the front, the lower, and the right. The escape portion 610 is provided such that an opening surface as viewed from the third direction (front-rear direction) is enlarged from the rear toward the front.

The dimension of the main piece 61 in the longitudinal direction (vertical direction) is larger on the second end (rear end) side in the width direction than on the first end (front end) side in the width direction. Further, a second end (rear end) of the main piece 61 in the width direction is exposed from the housing 1 at one end side (rear side) of the housing 1 in the third direction. One surface (rear surface) of the second end of the main piece 61 in the width direction is substantially coplanar with one surface (rear surface) of the plurality of tabs 2, and is a bonding surface bonded to the substrate 7 by, for example, soldering. That is, the connection terminal 6 further has a bonding portion 611 bonded to the substrate 7. The joint portion 611 is provided at a second end (rear end) of the main piece 61 in the width direction, that is, at one end on the bottom wall 11 side.

Two recesses 612 are provided at a second end (rear end) of the main piece 61 in the width direction. Both the recesses 612 are recessed in a direction along the thickness direction of the housing 1 (front direction in this case). This direction corresponds to a direction in which the connection terminal 6 is pushed into the second peripheral wall 122, in other words, a direction from one end (rear end) of the main piece 61 on the bottom wall 11 side to the other end (front end). Further, the two concave portions 612 are connected, and a portion where the two concave portions 612 are connected is also recessed in the direction (forward) along the third direction. That is, the concave portion 612 is provided at a second end (rear end) in the width direction of the main piece 61, that is, at one end on the side of the bottom wall 11, and is recessed toward a direction (front) in which the connection terminal 6 is pushed into the second peripheral wall 122. In other words, the recess 612 is provided at one end on the bottom wall 11 side, and is recessed from the one end on the bottom wall 11 side toward the other end.

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 therebetween in the first direction (left-right direction), and is exposed from the second peripheral wall 122. 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 122. The opposing piece 62 of the connection terminal 6 on the second side (right side) in the first direction is exposed from the right side of the second peripheral wall 122.

A gap is provided between the opposing piece 62 and the main piece 61. The opposing piece 62 and the connecting piece 63 of the connection terminal 6 are not held by the housing 1. Therefore, the opposing piece 62 and the connecting piece 63 can be elastically deformed. In particular, the opposing piece 62 is elastically deformable in the first direction (left-right direction). That is, in the connection terminal 6, the portions (the facing pieces 62 and the connecting pieces 63) not held by the housing 1 can be elastically deformed.

The opposing piece 62 is provided with a projection 621 projecting in a direction along the first direction (left-right direction). Specifically, a protrusion 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 projection 621 projecting 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 protruding toward a direction along the direction in which the pair of second peripheral walls 122 are arranged.

In the present embodiment, the projection 621 extends from the second end (rear end) of the opposing sheet 62 in the longitudinal direction along the third direction (front-rear direction). That is, the protrusion 621 extends in a direction orthogonal to the bottom wall 11 of the housing 1. Further, the projection 621 has a taper at one end (tip) on the side of the connecting piece 63, which becomes smaller as it approaches the connecting piece 63 and projects from the opposite piece 62. Due to this taper, the projection 621 is less likely to be locked to a mounting metal fitting 5A (described later) of the other connector 102 when the connector 101 is connected to the other connector 102.

In the present embodiment, the connection terminal 6 on the first side (left side) in the first direction can be electrically connected to the pair of upper and lower power supply terminals 4 via the conductor of the substrate 7 in the state where the joining portion 611 is joined to the substrate 7. Similarly, the connection terminal 6 on the second side (right side) in the first direction can be 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 joining part 611 is joined to the substrate 7. That is, some of the plurality of contacts 2 (power supply terminals 4) are electrically connected to the connection terminals 6 in an equipotential manner.

(3) Another connector

Next, another connector 102 corresponding to the connector 101 of the present embodiment will be described with reference to B in fig. 7 to 12.

(3.1) integral Structure

First, the overall structure of the other connector 102 of the present embodiment will be described in detail. The other connector 102 of the present embodiment is a receptacle (female connector), and includes the other-connector-side housing 1A, a plurality of other-connector-side contacts 2A, and a pair of other-connector-side attachment fittings 5A. In the following description, the other-connector-side housing 1A, the other-connector-side joint 2A, and the other-connector-side mounting fitting 5A will be referred to simply as a "housing 1A", a "joint 2A", and a "mounting fitting 5A", respectively, in principle. The mounting metal fitting 5A is described in detail in "(3.2) mounting metal fitting".

The housing 1A is a flat rectangular parallelepiped shape elongated in the first direction (the left-right direction), and is a resin molded body having insulating properties. In the present embodiment, the housing 1A is an insert-molded article in which the pair of attachment fittings 5A are inserts. The housing 1A has a bottom wall 11A, a peripheral wall 12A, and a table portion 16. The bottom wall 11A is plate-shaped and long in the first direction (left-right direction), and constitutes a bottom of the housing 1A. The peripheral wall 12A projects forward from the peripheral edge 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 periphery of the bottom wall 11A. Here, the "plan view" refers to a view 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 in the first direction among the peripheral walls 12A. The plurality of joints 2A are housed in the plurality of housing portions 17 described below in each of the pair of first peripheral walls 121A, and the plurality of joints 2A are held in a state aligned in one direction (left-right direction). That is, the peripheral wall 12A is provided with a plurality of joints 2A. In the present embodiment, the pair of first peripheral walls 121A hold four tabs 2A, respectively.

The table portion 16 is a rectangular parallelepiped shape elongated in the first direction (the left-right direction), and protrudes forward from the center of the bottom wall 11A. A portion surrounded by the bottom wall 11A, the peripheral wall 12A, and the step portion 16 constitutes a fitting recess 13A into which the connector 101 is fitted. Specifically, the pair of first peripheral walls 121 of the connector 101 and the pair of second peripheral walls 122 of the connector 101 are fitted in the fitting recess 13A. Thereby, the connector 101 is connected to the other connector 102.

The tab 2A is a metal molded body made of a metal material such as a copper alloy. Further, the tab 2A is plated with gold. Note that gold plating may not be applied to the contact 2A. The connector 2A includes a spring piece 24, a rising piece 25, a rising piece 26, and a terminal piece 27, which are integrally formed (see B of fig. 11).

The spring piece 24 is configured such that the tip end thereof is bent into a horseshoe shape and elastically deformed in the second direction (vertical direction). That is, the spring pieces 24 are configured to be pressed by the corresponding contacts 2 in a state where the plurality of contacts 2 of the connector 101 are inserted into the fitting recesses 13A, and to generate elastic force toward the corresponding contacts 2.

The riser 25 is plate-shaped. The first end (rear end) of the rising piece 25 is formed integrally with the spring piece 24. The rising piece 25 is configured to contact the corresponding contact 2 in a state where the plurality of contacts 2 of the connector 101 are inserted into the fitting recess 13A. In addition, the rising piece 25 is formed integrally with a projection 251 that projects toward the spring piece 24. The projections 251 are aligned with the projections 221 of the corresponding contacts 2 in the third direction (front-rear direction) in a state where the plurality of contacts 2 of the connector 101 are inserted into the fitting recesses 13A, and are positioned forward of the projections 221 (see fig. 14). That is, as described above, the projections 251 are locked to the projections 221 of the corresponding header 2, thereby constituting a lock mechanism.

The rising and falling pieces 26 are plate-shaped. The rising and lowering piece 26 has a first end (front end) bent in an inverted U shape and is integrally formed with a second end (front end) of the rising and lowering piece 25.

The terminal piece 27 has a plate shape. The terminal piece 27 is formed integrally with the second end (rear end) of the rising and falling piece 26. The tip of the terminal piece 27 is exposed from the case 1A on one end side (rear side) in the third direction. One surface (rear surface) of the terminal piece 27 is a bonding surface to be bonded to the substrate 7 by, for example, soldering.

The plurality of contacts 2A are roughly divided into signal terminals 3A for signal transmission and power terminals 4A electrically connected to a power supply, similarly to the connector 101. In the present embodiment, as in the case of the connector 101, the eight contacts 2A include four signal terminals 3A and four power supply terminals 4A. In the present embodiment, two signal terminals 3A and two power supply terminals 4A are provided in the arrangement direction (the left-right direction) on each of the first peripheral walls 121A of the pair of first peripheral walls 121A. In addition, two signal terminals 3A are provided on each of the pair of first peripheral walls 121A so as to be sandwiched between two power supply terminals 4A.

In the present embodiment, the power supply terminal 4A is formed in a shape in which three signal terminals 3A are arranged in one direction (left-right direction) and are integrally formed, similarly to the power supply terminal 4 of the connector 101. That is, in the present embodiment, the width dimension (the dimension in the first direction (the left-right direction)) of the power supply terminal 4A is made larger than the width dimension of the signal terminal 3A. Thus, the impedance of the power supply terminal 4A is made smaller than the impedance of the signal terminal 3A, and the rated current of the power supply terminal 4A is made larger than the rated current of the signal terminal 3A. In the power supply terminal 4A, the three spring pieces 24 are formed integrally with the first end (rear end) of the rising piece 25 at intervals in the first direction (left-right direction). The terminal piece 27 of the power terminal 4A is integrally formed with two projecting pieces 271 projecting outward in the second direction (vertical direction) from one end. Therefore, when the terminal piece 27 of the power terminal 4A is joined to the substrate 7 by, for example, soldering, the solder easily spreads to the region between the two projecting pieces 271, and fillets are easily formed. Therefore, in this structure, the power supply terminal 4A can be firmly bonded to the substrate 7.

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

The housing 1A has a plurality of (here, eight) receiving portions 17 corresponding to the plurality of joints 2A one-to-one. The plurality of receiving portions 17 penetrate the bottom wall 11A in the thickness direction (front-rear direction). The plurality of contacts 2A are pushed into the housing 17 from the rear, and are housed in the housing 17.

The plurality of receiving portions 17 are provided so as to be bisected on both sides in the second direction (vertical direction) across the table portion 16. The plurality of receiving portions 17 located on both sides of the table portion 16 in the second direction are arranged at substantially equal intervals along the first direction (the left-right direction). Here, the power supply terminals 4A are housed as the contacts 2A in two of the four housing sections 17 located on the first side (upper side) in the second direction of the table section 16 and located on both sides in the first direction (left-right direction). In addition, the power supply terminals 4A are also housed as the contacts 2A in two of the four housing sections 17 located on the second side (lower side) in the second direction of the table section 16 and located on both sides in the first direction, respectively. The remaining four receiving portions 17 receive the signal terminals 3A as the contacts 2A, respectively.

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

(3.2) mounting fittings

Next, the mounting metal fitting 5A in the other connector 102 according to the present embodiment will be described in detail with reference to fig. 12a and 12B. In the present embodiment, the attachment fittings 5A are provided at both end portions of the housing 1A in the first direction (left-right direction), respectively. In the following description, the mounting metal fitting 5A attached to the first end (left end) of the housing 1A in the first direction is described as an example in principle, but the mounting metal fitting 5A attached to the second end (right end) of the housing 1A in the first direction has the same configuration.

The attachment fitting 5A is a metal molded body made of a metal material such as a copper alloy. The mounting fittings 5A are used to improve the strength of the housing 1A. The mounting fixture 5A includes a first mounting piece 51, a second mounting piece 52, and a third mounting piece 53 as a mounting member 50 mounted to the housing 1A. The first mounting piece 51 has a rectangular plate shape that is long in the third direction (front-rear direction). The first attachment piece 51 covers at least a part of the inner surface S1 of the peripheral wall 12A in a state where the attachment member 50 is attached to the housing 1A. Specifically, the first attachment piece 51 is attached to the housing 1A in a state of penetrating the bottom wall 11A in the third direction (front-rear direction), and covers the inner surface S1 of the peripheral wall 12A in the third direction (see fig. 15 a and 15B). A first end (tip) of the first mounting piece 51 in the longitudinal direction is integrally formed with a first end of the second mounting piece 52. Further, a second end (rear end) in the longitudinal direction of the first attachment piece 51 is formed integrally with the third attachment piece 53.

The first end of the second mounting piece 52 is coupled to the first end (tip) of the first mounting piece 51 in the longitudinal direction. A second end of the second attachment piece 52 faces a projecting wall 19 (described later). The second attachment piece 52 covers at least a part of the coupling surface S3 that couples the outer surface S2 and the inner surface S1 of the peripheral wall 12A in the state where the attachment member 50 is attached to the housing 1A. In the present embodiment, the connection surface S3 is the distal end portion of the first peripheral wall 121A (or the second peripheral wall 122A), and constitutes the outer surface of a portion having a trapezoidal shape in plan view (see fig. 15 a and 15B). Here, the "plan view" means a view from a first direction (left-right direction) when the first peripheral wall 121A is an object, and a view from a second direction (up-down direction) when the second peripheral wall 122A is an object.

The mounting member 50 does not have a portion covering the outer side surface S2 of the peripheral wall 12A. That is, the mounting member 50 does not have a portion located on the opposite side of the first mounting piece 51 with the peripheral wall 12A therebetween. In other words, the mounting member 50 does not have a portion that is coupled to the second end of the second mounting piece 52 and extends from the second end of the second mounting piece 52 along the outer side surface S2 of the peripheral wall 12A. In further other words, the mounting member 50 does not have a portion that sandwiches the peripheral wall 12A between the mounting member 50 and the first mounting piece 51 in the thickness direction of the peripheral wall 12A.

In the present embodiment, the mounting member 50 includes a plurality of (three in this case) pieces 54 as one piece 54 of the first mounting piece 51 and the second mounting piece 52. Specifically, in the attachment fitting 5A on the first end (left end) side in the first direction, the two segments 54 are attached to the first ends (left ends) in the longitudinal direction of the pair of first peripheral walls 121A, respectively. In addition, the remaining one of the tabs 54 is attached to the second peripheral wall 122A on the first side (left side) in the first direction. Similarly, in the mounting metal 5A on the second side (right side) in the first direction, the two segments 54 are mounted to the second ends (right ends) of the pair of first peripheral walls 121A in the longitudinal direction, respectively. The remaining one of the segments 54 is attached to the second peripheral wall 122A on the second end (right end) side in the first direction of the housing 1A. That is, the three sheets 54 are provided on the pair of first and second

peripheral walls

121A, 122A of the peripheral wall 12A, respectively.

The third mounting piece 53 has a rectangular plate shape that is long in the second direction (vertical direction). The third mounting piece 53 is integrally provided with three pieces 54. Specifically, both ends in the longitudinal direction (vertical direction) of the third mounting piece 53 are integrally formed with the second ends (rear ends) in the longitudinal direction of the pair of upper and lower first mounting pieces 51, respectively. In addition, in the mounting fitting 5A on the first side (left side) in the first direction, one end (left end) in the width direction of the third mounting piece 53 is formed integrally with the second end (rear end) in the longitudinal direction of the first mounting piece 51. Similarly, in the mounting bracket 5A on the second side (right side) in the first direction, one end (right end) in the width direction of the third mounting piece 53 is formed integrally with the second end (rear end) in the longitudinal direction of the first mounting piece 51.

Here, as described above, the first attachment piece 51 is attached to the housing 1A in a state of penetrating the bottom wall 11A in the third direction (front-rear direction). Therefore, the third mounting piece 53 formed integrally with the second end (rear end) in the longitudinal direction of the first mounting piece 51 is exposed from the housing 1A at one end side (rear side) in the third direction. (refer to fig. 8). That is, the first mounting piece 51 penetrates the bottom wall 11A in the thickness direction of the bottom wall 11A. The third mounting piece 53 extends along the bottom wall 11A from one end of the first mounting piece 51 on the bottom wall 11A side.

One surface (rear surface) of the third mounting piece 53 is substantially coplanar with one surface (rear surface) of the plurality of tabs 2A, and is joined to the substrate 7 by soldering, for example. That is, the third mounting piece 53 has a bonding portion 511 bonded to the substrate 7. In other words, the mounting member 50 has a bonding portion 511 bonded to the substrate 7. The joint portion 511 can be said to be provided at one end (here, the third mounting piece 53) of the first mounting piece 51 on the bottom wall 11A side.

The third mounting piece 53 has a recess 531. In the mounting fitting 5A on the first side (left side) in the first direction, a recess 531 is recessed from one end (right end) to the other end (left end) in the width direction of the third mounting piece 53. In addition, in the mounting fitting 5A on the second side (right side) in the first direction, the recess 531 is recessed from one end (left end) to the other end (right end) in the width direction of the third mounting piece 53. That is, the third mounting piece 53 has a recess 531 recessed along the bottom wall 11A in a plan view. Here, the "plan view" refers to a view from the third direction (front-rear direction).

The third mounting piece 53 has a plurality of (here, two) terminal portions 532. The two terminal portions 532 are formed integrally with the third mounting piece 53 so as to protrude from both ends in the longitudinal direction (vertical direction) of the third mounting piece 53. The terminal portion 532 has a rectangular plate shape which is long along the second direction (vertical direction). The terminal portion 532 on the first side (upper side) in the second direction is aligned with the plurality of contacts 2A on the first side (upper side) in the second direction in the first direction (left-right direction). Similarly, the terminal portion 532 on the second side (lower side) in the second direction is aligned with the plurality of contacts 2A on the second side (lower side) in the second direction in the first direction (left-right direction). One surface (rear surface) of the terminal portion 532 is substantially coplanar with one surface (rear surface) of the plurality of contacts 2A, and is a bonding surface bonded to the substrate 7 by soldering, for example.

Here, the housing 1A is provided with a plurality of (six in this case) exposed portions 111 (see fig. 8 and 10). Specifically, on a first side (left side) in the first direction of the housing 1A, the three exposed portions 111 are provided at first ends (left ends) in the first direction of the pair of first peripheral walls 121A and the second peripheral wall 122A, respectively. On a second side (right side) in the first direction of the housing 1A, the three exposed portions 111 are provided at a second end (right end) in the first direction of the pair of first peripheral walls 121A and the second peripheral wall 122A, respectively.

The exposed portion 111 is recessed forward from the rear surface of the peripheral wall 12A, and a part of the corresponding first attachment piece 51 is exposed from the housing 1A. For example, on a first side (left side) in the first direction, the upper, lower, and left exposed portions 111 expose portions of the upper, lower, and left first mounting pieces 51 from the case 1A, respectively. That is, the exposed portion 111 is recessed in the thickness direction (front-rear direction) of the bottom wall 11A, and a part of the mounting member 50 is exposed from the housing 1A.

The case 1A has a plurality of (two in this case) thick portions 18 (see fig. 7 and 9). The two thick portions 18 are provided at both ends of the fitting recess 13A in the longitudinal direction (left-right direction). The thick portion 18 is formed integrally with the bottom wall 11A so as to protrude forward from the bottom wall 11A. The thick portion 18 has a triangular shape in plan view, and has a bottom surface contacting the bottom wall 11A, a rising surface contacting the corresponding first mounting piece 51, and an inclined surface facing outward. Here, the "plan view" refers to a view from the second direction (vertical direction). Specifically, the rising surface of the thick portion 18 provided on the first side (left side) in the first direction is in contact with the first mounting piece 51 provided on the left second peripheral wall 122A. In the thick portion 18 provided on the second side (right side) in the first direction, the rising surface is in contact with the first attachment piece 51 provided on the second peripheral wall 122A on the right side. Both thick portions 18 cover the boundary between the bottom wall 11A and the first mounting piece 51. That is, the thick portion 18 covers the boundary between the bottom wall 11A and the portion (first mounting piece 51) of the mounting member 50 that penetrates the bottom wall 11A and is exposed inside the peripheral wall 12A.

The housing 1A has a plurality of (six in this case) protruding walls 19 (see fig. 7 and 9). The six projecting walls 19 are each in the shape of a rectangular plate. Four of the six projecting walls 19 each project from one end (front end) of the first peripheral wall 121A in the third direction toward the direction (front) along the third direction. In addition, the remaining two projecting walls 19 each project from one end (front end) of the first peripheral wall 122A in the third direction toward the direction (front) along the third direction. In other words, the protruding wall 19 protrudes in the third direction (front-rear direction) from the connection surface S3 of the peripheral wall 12A. The six projecting walls 19 are opposed to the second ends of the corresponding second mounting pieces 52, respectively. Specifically, on the first side (upper side) in the second direction, the two projecting walls 19 are opposed to the second ends (upper ends) of the two second mounting pieces 52, respectively. On a second side (lower side) in the second direction, the two projecting walls 19 face second ends (lower ends) of the two second mounting pieces 52, respectively. Further, on a first side (left side) in the first direction, the projecting wall 19 faces a second end (left end) of the second mounting piece 52. Further, on a second side (right side) in the first direction, the projecting wall 19 faces a second end (right end) of the second mounting piece 52. In this way, the projecting wall 19 faces one end of the second mounting piece 52 on the outer side surface S2 side.

(4) Connection system

The connector 101 is mounted on a substrate 7 (hereinafter, also referred to as "first substrate 71") incorporated in an electronic device such as a smartphone (see fig. 13). In addition, another connector 102 corresponding to the connector 101 is similarly mounted on another substrate 7 (hereinafter, also referred to as "second substrate 72") incorporated in the electronic device (see fig. 13).

As shown in fig. 13 and 14, the first conductor of the first substrate 71 and the second conductor of the second substrate 72 are electrically connected by connecting the connector 101 to another connector 102. 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, the plurality of (four in this case) signal terminals 3 of the connector 101 are electrically connected to the corresponding plurality of (four in this case) signal terminals 3A of the other connector 102, respectively. The plurality of (four in this case) power supply terminals 4 of the connector 101 are electrically connected to the corresponding plurality of (four in this case) power supply terminals 4A of the other connector 102, respectively. That is, in the present embodiment, the connection system 100 is configured by the connector 101 and the other connector 102. In other words, the connection system 100 is provided with the connector 101 and the other connector 102. In fig. 13 and 14, the connector 101 is shown in a state of being reversed front to back. The same applies to a in fig. 15 and B in fig. 15 described later.

When the connector 101 is connected to the other connector 102, as shown in fig. 15A and 15B, the opposing piece 62 of the connection terminal 6 is pressed in the direction along the first direction (the left-right direction) by the first mounting piece 51 and the second mounting piece 52 of the mounting fixture 5A. Therefore, the connection terminal 6 is in contact with the attachment metal fitting 5A in a state of being elastically deformed in a 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 are in contact with the first mounting piece 51 of the mounting bracket 5A in a state of being elastically deformed in the right direction, respectively. In addition, in the connection terminal 6 on the second side (right side) in the first direction, the two opposing pieces 62 are in contact with the first mounting piece 51 of the mounting bracket 5A in a state of being elastically deformed in the left direction, respectively. That is, in a state where the connector 101 is connected to the other connector 102, the connection terminal 6 applies an elastic force to the mounting metal fitting 5A to return to an original state.

(5) Advantages of the invention

The connector 101 of the present embodiment includes a connection terminal 6 that can be electrically connected to a conductive portion (here, the mounting metal fitting 5A) having conductivity of another connector 102, in addition to the plurality of contacts 2. Therefore, when connecting the connector 101 to the other connector 102, not only the plurality of contacts 2 but also the connection terminal 6 can be electrically connected to the conductive portion of the other connector 102. In the connection terminal 6, at least a part of the portion not held by the housing 1 (the facing piece 62 and the connecting piece 63 in the present embodiment) is a portion that comes into contact with the conductive portion and is elastically deformable.

Here, a comparative example of the connector 101 of the present embodiment is described. The basic structure of the connector of the comparative example is the same as that of the connector 101 of the present embodiment, but does not include a connection terminal, and the mounting metal fitting has a structure capable of electrically connecting with a conductive portion of the other connector 102. In the connector of the comparative example, the mounting metal fitting can be electrically connected to the conductive portion of the other connector 102, as in the connector 101 of the present embodiment. However, the mounting fitting is used to ensure the strength of the housing, and therefore, even if it can be slightly elastically deformed, it is basically a structure that is difficult to be elastically deformed. Therefore, in the connector of the comparative example, in a state where the connector is connected to the other connector 102, the mounting metal fitting is difficult to contact the conductive portion of the other connector 102 in an elastically deformed state, and it is difficult to apply an elastic force.

On the other hand, in the connector 101 of the present embodiment, the portion of the connection terminal 6 not held by the housing 1 is elastically deformable. That is, in the connector 101 of the present embodiment, the connection terminal 6 can be brought into contact with the conductive portion of the other connector 102 in an elastically deformed state. Therefore, the connection terminal 6 can apply an elastic force to and contact the conductive portion of the other connector 102 in a state where the connector 101 is connected to the other connector 102. As described above, the connector 101 of the present embodiment can improve the reliability of electrical connection with the other connector 102 as compared with the connector of the comparative example.

In addition, in the connector 101 of the present embodiment, a part of the connection terminal 6 is pressed into at least one second peripheral wall 122 of the pair of second peripheral walls 122, and is held by the housing 1. That is, in the connector 101 of the present embodiment, the connection terminal 6, a part of which is elastically deformable, can be provided to the housing 1 by a simple process of pressing the connection terminal 6 into the second peripheral wall 122.

Here, in the connector 101 of the present embodiment, the connection terminal 6 is not used for the purpose of serving as a locking mechanism for maintaining the connection state between the connector 101 and the other connector 102, but is used for the purpose of electrically connecting a conductive portion of the other connector 102. Specifically, the connection terminal 6 can be electrically connected to a conductor (second conductor) of the other board 7 (second board 72) on which the other connector 102 is mounted, in a state where the connector 101 is connected to the other connector 102. In other words, in the connection system 100 including the connector 101, the other connector 102, and the substrate 7 on which the other connector 102 is mounted, the connection terminal 6 is electrically connected to the conductor of the substrate 7. In this structure, there are the following advantages: the connection terminal 6 can electrically connect the substrate 7 (first substrate 71) and the substrate 7 (second substrate 72) independently of the tab 2. For example, in the present embodiment, the plurality of contacts 2 include the signal terminals 3 and the power supply terminals 4, but all of the plurality of contacts 2 may be the signal terminals 3. In this case, the connection terminal 6 may be used as the power supply terminal 4.

In the connector 101 of the present embodiment, the connection terminal 6 is formed in a shape capable of elastically contacting the conductive portion of the other connector 102 regardless of the shape of the conductive portion of the other connector 102. In this structure, there are the following advantages: for example, even when the surface of the conductive portion of the other connector 102 facing the connector 101 is flat and the conductive portion is not elastic, the connection terminal 6 can elastically contact the conductive portion.

In the connector 101 of the present embodiment, since each of the plurality of contacts 2 has a lock mechanism, the lock mechanism is not required for the connection terminal 6. Therefore, in the present embodiment, the connection terminal 6 does not have a locking mechanism such as a recess. Therefore, the present embodiment has the following advantages: since the connection terminal 6 is not provided with a recess or the like, the amount of deflection can be obtained as much as possible, and the contact force with respect to the conductive portion of the other connector 102 can be easily ensured. It is arbitrary whether or not the connection terminal 6 has a lock mechanism.

In the connector 101 of the present embodiment, for example, as shown in fig. 1, the connection terminal 6 is held by the housing 1 so as to be positioned adjacent to the power supply terminal 4 without sandwiching the signal terminal 3 therebetween. In this configuration, since the area of the joint portion (conductor) between the power supply terminal 4 and the connection terminal 6 in the substrate 7 is easily obtained, there is an advantage that a large current flows easily when the structure is used for, for example, an application of branching a current flowing through the power supply terminal 4 to the connection terminal 6. The connection terminal 6 does not necessarily have to be located adjacent to the power supply terminal 4, and the signal terminal 3 may be disposed between the connection terminal 6 and the power supply terminal 4, for example.

In the connector 101 of the present embodiment, the projection 621 of the connection terminal 6 does not function as a locking mechanism, but functions as a removing mechanism for removing foreign matter adhering to the projection 621 and the surface of the conductive portion of the other connector 102. That is, even if the conductive portion of the other connector 102 does not have a structure corresponding to the locking mechanism, the projection 621 of the connection terminal 6 functions as a removal mechanism. In particular, in the present embodiment, as shown in fig. 6 a to 6C, for example, the projection 621 of the connection terminal 6 has a semi-cylindrical shape having an axis in the third direction (front-rear direction) perpendicular to the bottom wall 11, and has a curved surface in which the amount of projection from the opposing piece 62 decreases with distance from the axis. Therefore, the present embodiment has the following advantages: when the connection terminal 6 is brought into contact with the conductive portion of the other connector 102, even if foreign matter adheres to the connection terminal 6 or the conductive portion, the foreign matter is easily pushed out to the outside of the opposing piece 62 along the curved surface of the projection 621, and the foreign matter is easily removed.

In the connector 101 of the present embodiment, the main piece 61 of the connection terminal 6 does not protrude from the housing 1. In other words, the joint portion of the connection terminal 6 with the substrate 7 (first substrate 71) is not aligned with the plurality of tabs 2 in the arrangement direction (left-right direction) of the plurality of tabs 2. It is optional whether or not the main piece 61 of the connection terminal 6 protrudes from the housing 1.

(6) Modification example

Modifications of the present embodiment will be described below. The basic configuration of each of the modifications described below is the same as that of the connector 101 of the present embodiment, and therefore, the description of the same points is omitted. In addition, any of the modifications described below can be used in the connection system 100 instead of the connector 101 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 one of the third modification to the seventh modification.

(6.1) first modification

As shown in fig. 16 and 17, the connector 101 of the first modification does not include the attachment 5. In the present modification, only the connection terminal 6 is attached to each of the pair of second peripheral walls 122, and the pair of mounting fittings 5 is not attached thereto. In this structure, a space for mounting the mounting fitting 5 to the housing 1 does not need to be provided, and the size of the housing 1 (particularly, the size in the longitudinal direction of the housing 1) can be reduced. That is, in this configuration, the connector 101 can be downsized.

(6.2) second modification

The connector 101 of the second modification is different from the connector 101 of the first modification in that the main piece 61 of the connection terminal 6 has a pair of extension pieces 613, as shown in fig. 18. The pair of extension pieces 613 extend along the bottom wall 11 from the second end (rear end) of the main piece 61 in the width direction, that is, the end on the bottom wall 11 side. The pair of extension pieces 613 are integrally formed with the main piece 61 so as to protrude from both ends in the longitudinal direction (vertical direction) of the main piece 61. The extension piece 613 is a rectangular plate that is long in the second direction (vertical direction). The extension piece 613 on the first side (upper side) in the second direction is aligned with the plurality of tabs 2 on the first side (upper side) in the second direction in the first direction (left-right direction). Similarly, the extension piece 613 on the second side (lower side) in the second direction is aligned with the plurality of tabs 2 on the second side (lower side) in the second direction in the first direction (left-right direction).

One surface (rear surface) of the extension piece 613 is substantially coplanar with one surface (rear surface) of the plurality of tabs 2, and is a bonding surface bonded to the substrate 7 by soldering, for example. That is, in the present modification, the joint portion 611 is also provided to the extension piece 613. In this structure, the extension piece 613 can be bonded to the substrate 7 instead of the second piece 502 of the mounting fixture 5.

(6.3) third modification

In the connector 101 of the third modification, as shown in fig. 19 a to 19C, both the opposing pieces 62 of the connection terminal 6 do not have the projection 621. Even if the connection terminal 6 has a structure without the projection 621 as in the present modification, it is possible to apply an elastic force to the conductive portion of the other connector 102 and make contact with the conductive portion in a state where the connector 101 is connected to the other connector 102. In addition, in this structure, the connection terminal 6 can be easily manufactured as compared with the case where the connection terminal 6 has the projection 621.

(6.4) fourth modification

In the connector 101 of the fourth modification, as shown in fig. 20 a to 20C, the connection terminal 6 has one opposing piece 62 and one connecting piece 63. That is, in the present modification, the opposing piece 62 and the connecting piece 63 of the connection terminal 6 are not divided into two from the first end (front end) in the width direction of the main piece 61. In the present modification, two protrusions 621 are provided on one surface of one facing piece 62 at intervals in the second direction (vertical direction). In this configuration, the connection terminal 6 can be easily manufactured as compared with a configuration in which the opposing piece 62 and the connecting piece 63 are divided into two parts.

(6.5) fifth modification

In the connector 101 of the fifth modification, as shown in fig. 21a to 21C, the connection terminal 6 has one opposing piece 62 and one connecting piece 63. That is, in the present modification, the opposing piece 62 and the connecting piece 63 are not divided into two parts, as in the fourth modification. In the present modification, the opposing piece 62 has only one protrusion 621. In this structure, the connection terminal 6 can be easily manufactured as compared with a case where the connection terminal 6 has a plurality of protrusions 621.

(6.6) sixth modification

In the connector 101 of the sixth modification, as shown in fig. 22a to 22C, the connection terminal 6 has one opposing piece 62 and one connecting piece 63. That is, in the present modification, the opposing piece 62 and the connecting piece 63 are not divided into two parts, as in the fourth modification. In the present modification, the facing piece 62 does not have the projection 621. In this structure, the connection terminal 6 can be easily manufactured as compared with the case where the connection terminal 6 has the projection 621.

As in the fourth to sixth modifications, the connection terminal 6 is not limited to the configuration having two opposing pieces 62 and two connecting pieces 63, and may have a configuration having one opposing piece 62 and one connecting piece 63. The connection terminal 6 may have three or more opposing pieces 62 and three or more connecting pieces 63. The facing piece 62 is not limited to the structure having one projection 621, and may have a structure having two projections 621 or a structure having no projection 621. The opposing sheet 62 may have three or more protrusions 621.

(6.7) seventh modification

In the connector 101 of the present embodiment, as shown in fig. 2, for example, both ends of the bottom wall 11 in the first direction (left-right direction) are formed integrally with a pair of extension walls 112 extending along the first direction (left-right direction), respectively. In the connector 101 of the present embodiment, a gap is provided between the pair of extension walls 112 and the main piece 61 on either the first side (left side) or the second side (right side) in the first direction. In contrast, in the connector 101 of the seventh modification example, as shown in fig. 23, the pair of extension walls 112 are in contact with the main piece 61 on either the first side (left side) or the second side (right side) in the first direction, and no gap is provided between the pair of extension walls 112 and the main piece 61. In fig. 23, only the first side (left side) in the first direction of the connector 101 is illustrated.

Here, when a gap is provided between the pair of extending walls 112 and the main piece 61 as in the connector 101 of the present embodiment, the following advantages are provided. That is, when one surface (rear surface) of the second end in the width direction of the main piece 61 is joined to the substrate 7 by soldering, the solder diffuses into the gap, and fillets are easily formed. Therefore, in this structure, the main piece 61 (i.e., the connection terminal 6) is easily and firmly joined to the substrate 7, and as a result, the connector 101 is easily and firmly fixed to the substrate 7.

On the other hand, when no gap is provided between the pair of extension walls 112 and the main piece 61 as in the connector 101 of the present modification, the following advantages are obtained. That is, when stress is applied to the main piece 61 in the first direction (the left-right direction), the pair of extension walls 112 receives the stress, and the main piece 61 is less likely to be plastically deformed. Therefore, in this structure, the strength of the main piece 61 (i.e., the connection terminal 6) can be improved. In this configuration, when the connection terminal 6 is pushed into the groove 14 of the second peripheral wall 122, the main piece 61 is guided to the groove 14 by the pair of extension walls 112, so that the accuracy of positioning of the main piece 61 can be improved.

(6.8) other modifications

In the connector 101 of the present embodiment, the connection terminal 6 can be electrically connected to the mounting metal fitting 5A of the other connector 102, but the present invention is not limited thereto. For example, even when the other connector 102 does not have the mounting metal fitting 5A, the connection terminal 6 may be connected to a conductive portion having conductivity of the other connector 102.

In the connector 101 of the present embodiment, one connection terminal 6 is provided in each of the pair of second peripheral walls 122, but another configuration may be adopted. For example, a plurality of connection terminals 6 may be provided in each of the pair of second peripheral walls 122. In addition, the connection terminal 6 may be provided on the first peripheral wall 121 in addition to the second peripheral wall 122. In this case, the first peripheral wall 121 may have a groove into which a part of the connection terminal 6 (here, the main piece 61) is pushed.

In the connector 101 of the present embodiment, the dimension in the longitudinal direction of the first peripheral wall 121 is larger than the dimension in the longitudinal direction of the second peripheral wall 122, but other configurations may be adopted. For example, the dimension in the longitudinal direction of the first peripheral wall 121 may be smaller than the dimension in the longitudinal direction of the second peripheral wall 122. Further, the dimension in the longitudinal direction of the first peripheral wall 121 may be substantially the same as the dimension in the longitudinal direction of the second peripheral wall 122. In this case, the other connector 102 of the present embodiment may be appropriately modified according to the shape of the connector 101.

In the connector 101 of the present embodiment, the opposing piece 62 and the connecting piece 63 of the connecting terminal 6 are elastically deformable, but other configurations may be adopted. For example, only the opposing piece 62 of the connection terminal 6 may be elastically deformable. That is, the connection terminal 6 may be configured to be elastically deformable at a portion not held by the housing 1.

In the connector 101 of the present embodiment, in a state where the main piece 61 is held by the housing 1, gaps are generated in the width direction (vertical direction) of the housing 1 between the opposing piece 62 and the coupling piece 63, respectively, and the housing 1, but gaps may not be generated. That is, the opposing piece 62 and the connecting piece 63 may be elastically deformed in contact with the housing 1.

In the connector 101 of the present embodiment, the main piece 61 of the connection terminal 6 is held by the housing 1 in a plastically deformed state, but other configurations may be adopted. For example, the main piece 61 may be held by the case 1 in a state where the case 1 is plastically deformed without plastically deforming the main piece 61. Further, the main piece 61 may be held by the case 1 in a state where both the main piece 61 and the case 1 are plastically deformed.

The connector 101 of the second modification does not include the attachment fitting 5, but may include the attachment fitting 5. That is, both the connection terminal 6 having the extension piece 613 and the pair of mounting fittings 5 may be provided in each of the pair of second peripheral walls 122.

In the connectors 101 according to the third modification to the sixth modification, the main piece 61 of the connection terminal 6 does not have the relief portion 610, but other configurations may be adopted. That is, in the connectors 101 according to the third modification to the sixth modification, the main piece 61 of the connection terminal 6 may have the relief portion 610.

In the other connector 102 of the present embodiment, the mounting member 50 of the mounting metal fitting 5A has three pieces 54, but is not limited to this configuration. For example, the mounting member 50 may have only one tab 54, or may have only two tabs 54. In the case where the mounting member 50 has two pieces 54, the two pieces 54 are preferably provided on the pair of first peripheral walls 121A, respectively.

In the other connector 102 of the present embodiment, the projecting wall 19 is in contact with one end of the second mounting piece 52 on the side of the outer side surface S2, but may not be in contact. That is, a gap may be provided between the projecting wall 19 and one end of the second mounting piece 52 on the outer side surface S2 side.

In the other connector 102 of the present embodiment, the mounting member 50 has the third mounting piece 53, but other configurations may be adopted. For example, the mounting member 50 may not have the third mounting piece 53. In this configuration, a second end (rear end) in the longitudinal direction of the first mounting piece 51, that is, one end on the bottom wall 11A side is exposed from the case 1A on one end side (rear side) in the thickness direction of the case 1A. In this configuration, when one surface (rear surface) of the second end of the first mounting piece 51 in the longitudinal direction is substantially flush with one surface (rear surface) of the plurality of tabs 2A, the first mounting piece is bonded to the substrate 7 by soldering, for example. That is, in this case, it can be said that the joint portion 511 is provided at one end of the first mounting piece 51 on the bottom wall 11A side.

In the other connector 102 of the present embodiment, the third mounting piece 53 has a plurality of terminal portions 532, but another structure may be adopted. For example, the third mounting piece 53 may not have the terminal portion 532.

In the connection system 100 of the present embodiment, the connector 101 is a plug, and the other connector 102 is a socket, but the present invention is not limited thereto. That is, in the connection system 100, the connector 101 may be a receptacle and the other connector 102 may be a plug.

(embodiment mode 2)

(1) Detailed description of the invention

The following describes the connector 101 according to embodiment 2. Since the basic configuration of the connector 101 of the present embodiment is the same as that of the connector 101 of embodiment 1, the description of the same configuration is omitted. Further, the connector 101 of the present embodiment can form a connection system 100 with another connector 102, similarly to the connector 101 of embodiment 1.

The connector 101 of the present embodiment is different from the connector 101 of embodiment 1 in that the housing 1 is an insert-molded product in which the connection terminal 6 is an insert, as shown in fig. 24 to 27. In other words, the pair of connection terminals 6 are held by the pair of second peripheral walls 122 as inserts of the housing 1 which is an insert molding.

In the present embodiment, the main piece 61 and a part of the connecting piece 63 are held by the housing 1 as an insert of the housing 1 in the groove 14 of the second peripheral wall 122. That is, the connection terminal 6 is configured such that a part (a part of the main piece 61 and the connection piece 63) is held by the housing 1.

In the present embodiment, the wall portion 15 is provided between the facing piece 62 and the main piece 61 in the groove 14. The wall portion 15 has a rectangular plate shape that is long in the second direction (vertical direction). The wall portion 15 is formed integrally with the bottom wall 11 of the housing 1, and protrudes from the bottom wall 11 in a direction along the thickness direction of the bottom wall 11 (forward in this case). That is, the housing 1 further includes a wall portion 15 provided between the main piece 61 and the opposing piece 62.

A gap is provided between the opposing piece 62 and the wall portion 15 (i.e., the main piece 61). The opposing piece 62 and the connecting piece 63 (except for a part of the connecting piece 63) of the connecting terminal 6 are not held by the housing 1. Therefore, the opposing piece 62 and the connecting piece 63 (except for a part of the connecting piece 63) can be elastically deformed. In particular, the opposing piece 62 is elastically deformable in the first direction (left-right direction). That is, in the connection terminal 6, the portion not held by the housing 1 (the facing piece 62 and the connection piece 63 (except for a part of the connection piece 63)) can be elastically deformed.

When the connector 101 of the present embodiment is connected to the other connector 102, the opposing piece 62 of the connection terminal 6 is pressed in the direction along the first direction (the left-right direction) by the first mounting piece 51 and the second mounting piece 52 of the mounting fixture 5A, similarly to the connection terminal 6 of embodiment 1 (see a of fig. 28 and B of fig. 28). Therefore, the connection terminal 6 is in contact with the attachment metal fitting 5A in a state of being elastically deformed in a direction along the first direction (left-right direction). That is, in a state where the connector 101 is connected to the other connector 102, the connection terminal 6 applies an elastic force to the mounting metal fitting 5A to return to an original state.

In the connector 101 of the present embodiment, the connection terminal 6, a part of which is elastically deformable, can be provided in the housing 1 by a simple process such as insert molding.

(2) Modification example

Modifications of the present embodiment will be described below. The basic configuration of each of the modifications described below is the same as that of the connector 101 of the present embodiment, and therefore, the description of the same points is omitted. In addition, any of the modifications described below can be used in the connection system 100 instead of the connector 101 of the present embodiment. The modification described below can be applied in appropriate combination with the modification of the connector 101 according to embodiment 1.

(2.1) first modification

As shown in fig. 29 and 30, the connector 101 of the first modification differs from the connector 101 of the present embodiment in that the attachment 5 is not provided. In the present modification, only the connection terminal 6 is attached to each of the pair of second peripheral walls 122, and the pair of mounting fittings 5 is not attached thereto. In this structure, a space for mounting the mounting fitting 5 to the housing 1 does not need to be provided, and the size of the housing 1 (particularly, the size in the longitudinal direction of the housing 1) can be reduced. That is, in this configuration, the connector 101 can be downsized.

(2.2) second modification

As shown in fig. 31, the connector 101 of the second modification is different from the connector 101 of the first modification in that the main piece 61 of the connection terminal 6 has a pair of extension pieces 613. In this structure, the extension piece 613 can be bonded to the substrate 7 instead of the second piece 502 of the mounting fixture 5.

(2.3) third modification

In the connector 101 of the present embodiment, as shown in fig. 25, for example, both ends of the bottom wall 11 in the first direction (left-right direction) are formed integrally with a pair of extension walls 112 extending along the first direction (left-right direction), respectively. In the connector 101 of the present embodiment, the pair of extension walls 112 contact the main piece 61 on either the first side (left side) or the second side (right side) in the first direction, and no gap is provided between the pair of extension walls 112 and the main piece 61. In contrast, in the connector 101 of the third modification, as shown in fig. 32, a gap is provided between the pair of extension walls 112 and the main piece 61 on either the first side (left side) or the second side (right side) in the first direction. In fig. 32, only the first side (left side) in the first direction of the connector 101 is illustrated.

In this configuration, when one surface (rear surface) of the second end in the width direction of the main piece 61 is joined to the substrate 7 by soldering, the solder diffuses into the gap, and the fillet is easily formed. Therefore, in this structure, the main piece 61 (i.e., the connection terminal 6) is easily and firmly joined to the substrate 7, and as a result, the connector 101 is easily and firmly fixed to the substrate 7.

The first modification to the third modification described above can be combined with any one of the third modification to the sixth modification of embodiment 1. That is, the connection terminal 6 of each of the first modification to the third modification may be replaced with the connection terminal 6 of any one of the third modification to the sixth modification of embodiment 1.

(conclusion)

As described above, the connector (101) of the first aspect includes the plurality of contacts (2), the housing (1), and the electronic component (6). A housing (1) holds a plurality of joints (2). The connection terminal (6) has conductivity and can be electrically connected to a conductive portion of another connector (102). The housing (1) has a bottom wall (11) and a peripheral wall (12) surrounding the bottom wall (11). The peripheral wall (12) has 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 connectors (2) in a state of being arranged in the arrangement direction. The pair of second peripheral walls (122) connect the ends of the pair of first peripheral walls (121) to each other. A part of the connection terminal (6) is held by at least one second peripheral wall (122) of the pair of second peripheral walls (122). At least a part of the connection terminal (6) not held by the housing (1) is a part that is in contact with the conductive part and is elastically deformable.

According to this configuration, when the connector (101) is connected to another connector (102), not only the plurality of contacts (2) but also the connection terminal (6) can be electrically connected to the conductive portion of the other connector (102). Further, according to this configuration, in a state where the connector (101) is connected to the other connector (102), the connection terminal (6) applies an elastic force to the conductive portion of the other connector (102) and comes into contact therewith. Therefore, according to this structure, the reliability of the electrical connection with the other connector (102) can be improved.

In addition, in the connector (101) according to the second aspect, in addition to the first aspect, the connection terminal (6) is electrically connected to some of the plurality of contacts (2) at the same potential.

According to this configuration, the connection terminal (6) can function as a part of the contact (2). Furthermore, according to this configuration, since the current flowing through a part of the terminal (2) branches to the connection terminal (6), the rated current of a part of the terminal (2) including the connection terminal (6) can be increased.

For example, the connection terminal (6) is assumed to be equipotentially electrically connected to the power supply terminal (4). In this configuration, the connection terminal (6) functions as a power supply terminal (4). In addition, in this configuration, since currents flow through the connection terminal (6) and the power supply terminal (4), respectively, the rated current of the power supply terminal (4) including the connection terminal (6) can be increased.

Here, when the connection terminal (6) is electrically connected to the power supply terminal (4) in an equipotential manner and the connection terminal (6) has the protrusion (621), or when the connection terminal has the protrusion (621) extending in a direction orthogonal to the bottom wall (11), the following advantages are provided. In other words, in the above case, the contact resistance at the contact portion between the connection terminal (6) and the conductive portion of the other connector (102) is reduced by the projection (621), and therefore, the current easily flows through the connection terminal (6). Therefore, it is easy to cause the current to flow through the connection terminal (6) and the power supply terminal (4) in a balanced manner, and the current is not likely to flow intensively through the power supply terminal (4). As a result, the rated current of the power supply terminal (4) including the connection terminal (6) can be further increased.

However, the configuration of the second aspect is not essential, and all the contacts (2) and the connection terminals (6) may be electrically connected to each other at different potentials. For example, in a substrate (first substrate (71)) on which the connector (101) is mounted, a conductor on which the connection terminal (6) is mounted and a conductor on which the contact (2) is mounted may be different from each other. That is, the connection terminal (6) may be used as a terminal independent from the terminal (2).

In addition, in the connector (101) according to the third aspect, the plurality of contacts (2) include signal terminals (3) for signal transmission and power supply terminals (4) electrically connected to a power supply in addition to the second aspect. The connection terminal (6) is electrically connected to the power supply terminal (4) at the same potential.

According to this configuration, since currents flow through the connection terminal (6) and the power supply terminal (4), the rated current of the power supply terminal (4) including the connection terminal (6) can be increased.

In addition, in the connector (101) of the fourth aspect, in addition to any one of the first to third aspects, the connection terminal (6) is electrically connected to a conductor (second conductor) included in a substrate (second substrate (72)) on which the other connector (102) is mounted, in a state in which the connector (101) is connected to the other connector (102).

According to this structure, the connection terminal (6) can electrically connect the substrate (7) (first substrate (71)) and the substrate (7) (second substrate (72)) independently of the tab (2).

In addition, in the connector (101), in addition to any one of the first to third aspects, a plurality of joints (2) may be provided in each of the pair of first peripheral walls (121).

According to this configuration, the other connector (102) can be electrically connected to the connector (101) regardless of the orientation of the other connector (102) along the first direction (left-right direction). However, this structure is not essential, and the plurality of joints (2) may be provided only on one of the pair of first peripheral walls (121).

In addition, in the connector (101) according to the fifth aspect, in addition to any one of the first to fourth aspects, the connection terminal (6) is provided in each of the pair of second peripheral walls (122).

According to this configuration, the other connector (102) can be electrically connected to the connector (101) regardless of the orientation of the other connector (102) along the first direction (left-right direction). However, this structure is not essential, and the connection terminal (6) may be provided only on one of the pair of second peripheral walls (122).

In addition, in the connector (101) according to a sixth aspect, in addition to any one of the first to fifth aspects, the connection terminal (6) includes a main piece (61), an opposing piece (62), and a connection piece (63). The main piece (61) is held by the housing (1). The opposing piece (62) faces the main piece (61) with a gap therebetween, and is exposed from the second peripheral wall (122). The connecting piece (63) connects the ends of the main piece (61) and the opposing piece (62) to each other.

According to this structure, since there is a gap between the main piece (61) and the opposing piece (62), the opposing piece (62) is easily elastically deformed and is also hardly plastically deformed. However, this structure is not essential, and for example, the main piece (61) and the connecting piece (63) may be held by the case (1), and only the facing piece (62) may not be held by the case (1). The connection terminal (6) may not have the main piece (61), the connection piece (63) may be held by the housing (1), and only the facing piece (62) may not be held by the housing (1).

In addition, in the connector (101) according to the seventh aspect, the connection terminal (6) further includes a bonding portion (611) bonded to the substrate (7) in addition to the sixth aspect. The joint (611) is provided at one end of the main piece (61) on the bottom wall (11) side.

According to this configuration, the connection terminal (6) can be fixed to the substrate (7) by joining the joining portion (611) to the substrate (7) by soldering. Therefore, according to this structure, the strength of the connection terminal (6) can be improved as compared with the case where the joint portion (611) is not provided. However, this structure is not essential, and the connection terminal (6) may not have the joint portion (611). That is, the connection terminal (6) may not be fixed to the substrate (7).

In addition, in the connector (101) according to the eighth aspect, in addition to the seventh aspect, the main piece (61) has an extension piece (613). The extension piece (613) extends from one end of the main piece (61) on the bottom wall (11) side along the bottom wall (11). The joint part (611) is also arranged on the extension piece (613).

According to the structure, the area of the part of the connecting terminal (6) fixed on the substrate (7) is increased according to the amount of the extension piece (613). Therefore, according to this configuration, the connection terminal (6) can be more firmly fixed to the substrate (7) than in the case where the extension piece (613) is not provided, and the strength of the connection terminal (6) can be further improved. However, this structure is not essential, and the main piece (61) may not have the extension piece (613). In addition, when the main piece (61) has the extension piece (613), the extension piece (613) may not be provided with the joint portion (611).

In addition, a connector (101) according to a ninth aspect is provided with the mounting metal fitting (5) mounted to the housing (1) in addition to any one of the first to eighth aspects. Of the pair of second peripheral walls (122), the second peripheral wall (122) provided with the connection terminal (6) is an insert-molded article in which the attachment fitting (5) is an insert.

According to this configuration, since the strength of the second peripheral wall (122) is increased by the mounting metal fitting (5), the stress applied to the second peripheral wall (122) to which the mounting metal fitting (5) is mounted is less likely to be transmitted to the connection terminal (6) provided in the second peripheral wall (122). Therefore, according to this structure, the connection terminal (6) is less likely to be plastically deformed. In addition, according to the structure, the shape of the connecting terminal (6) is not easy to change, so that the position deviation of the connecting terminal (6) relative to the second peripheral wall (122) can be reduced. In addition, for example, when the mounting fitting (5) is fixed to the substrate (7) by soldering, the second peripheral wall (122) is also fixed to the substrate (7), and therefore the connection terminal (6) provided in the second peripheral wall (122) is easily held by the second peripheral wall (122). However, this structure is not essential, and the attachment fitting (5) may be attached to the second peripheral wall (122) by being pushed into the second peripheral wall (122). The connector (101) may not be provided with the mounting member (5).

In addition, in the connector (101) according to the tenth aspect, in addition to the sixth aspect, the opposing piece (62) has a protrusion (621) that protrudes toward a direction along which the pair of second peripheral walls (122) are arranged.

According to this configuration, in a state where the connector (101) is connected to the other connector (102), the connection terminal (6) is more likely to contact the conductive portion of the other connector (102) than in a case where the protrusion (621) is not provided. Therefore, according to this configuration, the contact resistance at the contact portion between the connection terminal (6) and the conductive portion can be reduced, and the current can be made to flow easily through the connection terminal (6). In addition, according to this configuration, the possibility of occurrence of contact failure due to foreign matter can be reduced. That is, when another connector (102) is connected to the connector (101), the protrusion (621) moves while wiping the surface of the conductive portion, and therefore foreign matter adhering to the surfaces of the protrusion (621) and the conductive portion can be removed. However, this structure is not essential, and the connection terminal (6) may not have the projection (621).

In addition, in the connector (101) of the eleventh aspect, in addition to the tenth aspect, the projection (621) extends in a direction orthogonal to the bottom wall (11).

According to this structure, the contact area of the protrusion (621) that is in contact with the conductive portion of the other connector (102) is increased. Therefore, according to this configuration, the contact resistance at the contact portion between the connection terminal (6) and the conductive portion can be further reduced, and the current can be made to flow easily through the connection terminal (6). Further, according to this configuration, when another connector (102) is connected to the connector (101), the area of the surface of the conductive portion wiped by the projection (621) is increased as compared with a case where the projection (621) does not extend in the direction orthogonal to the bottom wall (11). Therefore, according to the structure, foreign matters attached to the surfaces of the protrusion part (621) and the conductive part can be easily removed, and the possibility of poor contact caused by the foreign matters is further reduced. However, this structure is not essential, and the projection 621 may not extend in the direction orthogonal to the bottom wall 11.

In addition, in the connector (101) according to the twelfth aspect, the connection terminal (6) has a plurality of opposing pieces (62) in addition to the sixth aspect.

According to this configuration, the reliability of electrical connection between the connection terminal (6) and the conductive portion of the other connector (102) can be improved as compared with a case where the connection terminal (6) has only one opposing piece (62). However, this structure is not essential, and the connection terminal (6) may have only one opposing piece (62).

In addition, in the connector (101) of the thirteenth aspect, in addition to any one of the first to twelfth aspects, the connection terminal (6) is held by the housing (1) by being partially pushed into at least one of the pair of second peripheral walls (122).

According to the structure, the connecting terminal (6) with a part capable of elastic deformation can be arranged on the shell (1) through a simple process of pressing the connecting terminal (6) into the second peripheral wall (122). However, this structure is not essential, and the connection terminal (6) may be held by the housing (1) by other means.

In addition, in the connector (101) of the fourteenth aspect, in addition to the sixth aspect, the connection terminal (6) is held by the housing (1) by being partially pushed into at least one second peripheral wall (122) of the pair of second peripheral walls (122). The main piece (61) has an escape portion (610). The escape part (610) is provided at a corner of one end of the main piece (61) that is connected to the connecting piece (63), and is recessed in a direction opposite to the direction in which the connection terminal (6) is pushed into the second peripheral wall (122).

According to the structure, when the main piece (61) is pressed into the second peripheral wall (122), a part of the second peripheral wall (122) is not easy to be cut. Therefore, according to the structure, foreign matters generated by cutting the second peripheral wall (122) are not easy to generate, and the foreign matters are not easy to adhere to the connecting terminal (6). However, this structure is not essential, and the main piece (61) may not have the escape portion (610).

In addition, in the connector (101) according to the fifteenth aspect, in addition to the seventh aspect, the main piece (61) further includes a recess (612). The recess (612) is provided at one end of the main piece (61) on the bottom wall (11) side, and is recessed from the one end on the bottom wall (11) side toward the other end.

According to this structure, when the joining part (611) is joined to the substrate (7) by soldering, the solder easily spreads into the recessed part (612), and fillets are easily formed. Therefore, according to this structure, the main piece (61) can be more firmly bonded to the substrate (7). However, this structure is not essential, and the main piece (61) may not have the recess (612).

In addition, in the connector (101) of the sixteenth aspect, in addition to any one of the first to twelfth aspects and the fifteenth aspect, the housing (1) is an insert-molded article in which the connection terminal (6) is an insert.

According to this configuration, a connection terminal (6) that is partially elastically deformable can be provided in the housing (1) by a simple process such as insert molding. However, this structure is not essential, and the connection terminal (6) may be held by the housing (1) by other means.

In addition, in the connector (101) according to the seventeenth aspect, in addition to the sixth aspect, the housing (1) is an insert-molded article in which the connection terminal (6) is an insert. The housing further has a wall portion (15) provided between the main piece (61) and the opposing piece (62).

According to this configuration, even if the opposing piece (62) attempts to be excessively elastically deformed, the opposing piece (62) comes into contact with the wall portion (15), thereby restricting the movement of the opposing piece (62). That is, according to this structure, the possibility that the opposing piece (62) is excessively elastically deformed can be reduced. However, this structure is not essential, and the case (1) may not have the wall portion (15).

The receptacle according to the eighteenth aspect is connected to the plug of the connector (101) according to any one of the first to seventeenth aspects, and is a receptacle of another connector (102). The receptacle has a plurality of other connector-side contacts (2A) electrically connected to the plurality of contacts (2) of the plug.

According to this configuration, it is possible to realize a receptacle capable of improving the reliability of electrical connection between a plug and a receptacle.

A connection system (100) according to a nineteenth aspect is provided with the connector (101) according to any one of the first to seventeenth aspects and another connector (102). The other connector (102) has a plurality of other-connector-side contacts (2A) electrically connected to the plurality of contacts (2).

According to this configuration, a connection system (100) can be realized, wherein the connection system (100) can improve the reliability of the electrical connection between the connector (101) and the other connector (102).

However, the connector (101) is not limited to the first to seventeenth aspects described above, and may be connected to another connector (102) of any one of the following first to eleventh aspects. That is, any one of the first to seventeenth aspects described above is not required as long as the connector (101) is connected to another connector (102) of any one of the first to eleventh aspects described below.

The other connector (102) of the first aspect is provided with a mounting fitting (5A). The mounting fitting (5A) is provided with a mounting member (50). The mounting member (50) is mounted to a housing (1A) of another connector (102) having a plurality of contacts (2A). The case (1A) has a bottom wall (11A) and a peripheral wall (12A) surrounding the bottom wall (11A). The mounting member (50) has a first mounting piece (51) and a second mounting piece (52). The first attachment piece (51) covers at least a part of the inner surface (S1) of the peripheral wall (12A). The second mounting piece (52) is connected to the first mounting piece (51) and covers at least a part of a connecting surface (S3) that connects the outer side surface (S2) and the inner side surface (S1) of the peripheral wall (12A). The mounting member (50) does not have a portion (hereinafter referred to as "opposite-side portion") located on the opposite side of the first mounting piece (51) with the peripheral wall (12A) therebetween.

According to this configuration, the volume ratio of the attachment metal fitting (5A) to the housing (1A) can be reduced as compared with a case where the attachment member (50) has an opposite side portion. Therefore, according to this configuration, the other connector (102) can be downsized compared to the case where the mounting member (50) has the opposite side portion. In addition, when the size of the other connector (102) is set to a predetermined size, the strength of the housing (1A) can be increased as compared with the case where the mounting member (50) has an opposite side portion.

In another connector (102) of a second aspect, in addition to the first aspect, the first mounting piece (51) penetrates the bottom wall (11A) in the thickness direction of the bottom wall (11A). The mounting member (50) further has a third mounting piece (53). The third mounting piece (53) extends from one end of the first mounting piece (51) on the bottom wall (11A) side along the bottom wall (11A).

According to this configuration, even if a stress (11A) is applied in the direction along the thickness direction of the bottom wall (11A) when the connector (101) is connected to another connector (102), the stress can be received by the third mounting piece (53). Therefore, according to this configuration, the strength of the bottom wall (11A), that is, the housing (1A), can be increased as compared with the case where the third attachment piece (53) is not provided. However, this structure is not essential, and the mounting member (50) may not have the third mounting piece (53). The first mounting piece (51) may not penetrate the bottom wall (11A).

In another connector (102) according to a third aspect, in addition to the second aspect, the third mounting piece (53) has a recess (531). The recess (531) is recessed along the bottom wall (11A) in a plan view.

According to the structure, when the third mounting piece (53) is connected to the substrate (7) by soldering, the solder is easily diffused to the recess (531), and the fillet is easily formed. Therefore, according to this configuration, when the third mounting piece (53) is bonded to the substrate (7), the third mounting piece (53) can be more firmly bonded to the substrate (7). However, this structure is not essential, and the third mounting piece (53) may not have the recess (531).

In another connector (102) according to a fourth aspect, in addition to any one of the first to third aspects, the mounting member (50) has a plurality of pieces (54) with the first mounting piece (51) and the second mounting piece (52) as one piece (54).

According to this structure, an external force applied to the other connector (102) can be received by the plurality of tabs (54). Therefore, according to this structure, the strength of the case (1A) can be improved as compared with the case where only one segment (54) is provided. However, this structure is not essential, and the mounting member (50) may have only one segment (54).

In another connector (102) according to a fifth aspect, in addition to the fourth aspect, the mounting member (50) has two blades (54). The two pieces (54) are attached to the pair of first peripheral walls (121A), respectively. The pair of first peripheral walls (121A) hold the plurality of connectors (2A) in the peripheral wall (12A) in an aligned state in the alignment direction.

According to this structure, external force applied to the pair of first peripheral walls (121A) can be received by the two pieces (54). Therefore, according to the structure, the strength of the pair of first peripheral walls (121A) can be improved, and as a result, the strength of the housing (1A) can be improved. However, this structure is not essential, and the segment (54) may be attached to a portion of the peripheral wall (12A) other than the pair of first peripheral walls (121A).

In another connector (102) according to a sixth aspect, in addition to the fourth aspect, the mounting member (50) has three blades (54). The three sheets (54) are respectively provided on a pair of a first peripheral wall (121A) and a second peripheral wall (122A) of the peripheral walls (12A). The pair of first peripheral walls (121A) hold the plurality of connectors (2A) in an aligned state in the alignment direction. The second peripheral wall (122A) connects the ends of the pair of first peripheral walls (121A) to each other.

According to this structure, external force applied to the pair of first peripheral walls (121A) and second peripheral walls (122A) can be received by the three group pieces (54). Therefore, according to this configuration, the strength of the pair of first peripheral wall (121A) and second peripheral wall (122A) can be increased, and as a result, the strength of the housing (1A) can be increased. However, this structure is not essential, and the segment (54) may be attached to a portion of the peripheral wall (12A) other than the pair of the first peripheral wall (121A) and the second peripheral wall (122A).

In another connector (102) according to a seventh aspect, in addition to any one of the first to sixth aspects, the mounting member (50) further includes a bonding portion (511) that is bonded to the substrate (7). The joint (511) is provided at one end of the first mounting piece (51) on the bottom wall (11A) side.

According to this configuration, when the mounting member (50) is bonded to the substrate (7), the portion of the first mounting piece (51) that is not bonded to the substrate (7) and the second mounting piece (52) are not fixed to the substrate (7). Therefore, according to this configuration, stress applied to the mounting member (50) when connecting the connector (101) and the other connector (102) can be reduced as compared with a case where the mounting member (50) has an opposite side portion.

That is, in the structure in which the mounting member (50) has the opposite side portion, the first mounting piece (51) and the opposite side portion sandwich the peripheral wall (12A). In this structure, when the opposite side portion is joined to the substrate (7), the first mounting piece (51), the second mounting piece (52), and the opposite side portion are less likely to be elastically deformed when the connector (101) is connected to the other connector (102). Therefore, in this structure, it is not easy to eliminate the external force applied to the other connector (102). On the other hand, in a configuration in which the mounting member (50) does not have an opposite side portion, the first mounting piece (51) and the second mounting piece (52) are easily elastically deformed when the connector (101) is connected to the other connector (102). Therefore, in this structure, the external force applied to the other connector (102) is easily eliminated, and as a result, the stress applied to the mounting member (50) can be reduced.

In addition, according to the structure, compared with the case that the opposite side part is jointed to the substrate (7), the residual stress of the mounting component (50) can be reduced. However, this structure is not essential, and the mounting member (50) may not have the engaging portion (511).

Another connector (102) according to an eighth aspect is provided with the mounting fitting (5A) according to any one of the first to seventh aspects, a housing (1A), and a plurality of joints (2A).

According to this configuration, compared to the case where the mounting member (50) has the opposite side portion, the other connector (102) can be realized, and the other connector (102) can be downsized. In addition, when the size of the other connector (102) is defined to be a predetermined size, the other connector (102) can be realized in which the strength of the housing (1A) can be improved as compared with the case where the mounting member (50) has an opposite side portion.

In another connector (102) according to a ninth aspect, in addition to the eighth aspect, the housing (1A) has an exposed portion (111). The exposed portion (111) is recessed in the thickness direction of the bottom wall (11A) and exposes a part of the mounting member (50) from the housing (1A).

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 component (5A) can be more firmly fixed to the substrate (7), and the strength of the mounting component (5A) can be further improved. In addition, when the mounting fitting (5A) is equipotentially and electrically connected to a part of the joint (2A), the impedance of the mounting fitting (5A) can be reduced. However, this structure is not essential, and the case (1A) may not have the exposed portion (111).

In another connector (102) according to a tenth aspect, in addition to the eighth or ninth aspect, the housing (1A) further includes a thick portion (18). The thick portion (18) covers the boundary between the bottom wall (11A) and a portion of the mounting member (50) that penetrates the bottom wall (11A) and is exposed inside the peripheral wall (12A).

According to this configuration, when the connector (101) is connected to the other connector (102), an external force applied to the other connector (102) can be received by the thick portion (18). Therefore, according to this configuration, external force is less likely to be transmitted to the bottom wall (11A) and the mounting member (50) than in the case where the thick portion (18) is not provided, and as a result, the strength of the housing (1A) can be increased. However, this structure is not essential, and the case (1A) may not have the thick portion (18).

In another connector (102) according to an eleventh aspect, in addition to any one of the eighth to tenth aspects, the housing (1A) further includes a protruding wall (19). The protruding wall (19) protrudes from the connecting surface (S3) in the thickness direction of the housing (1A) and faces one end of the second mounting piece (52) on the outer surface (S2) side.

According to this configuration, when an external force is applied in a direction toward an end (second end in this case) of the second mounting piece (52) located on the connecting surface (S3), the external force is easily received by the protruding wall (19). Therefore, according to this configuration, the external force is less likely to be transmitted to the second mounting piece (52), and as a result, the second mounting piece (52) is less likely to be deformed. However, this structure is not essential, and the case (1A) may not have the protruding wall (19).
