Description

Technical Field

[0001] The present disclosure relates to a connector.

Background Art

[0002] Conventionally, a connector that obtains an electrical connection state by bringing corresponding terminals into contact with each other by fitting a housing of a receptacle connector and a housing of a plug connector is known. As a prior art document disclosing this type of connector, for example, there is Patent Document 1 below. The connector (10) disclosed in Patent Document 1 is composed of a header (20) which is a plug connector and a socket (30) which is a receptacle connector, as shown in FIGS. 42 to 44. The header (20) includes a header-side signal terminal (22) and a header-side power supply terminal (23), and the socket (30) includes a socket-side signal terminal (32) and a socket-side power supply terminal (33).

[0003] In the connector (10) described in Patent Document 1, since the current supplied from the power line is larger than the current supplied from the signal line, the width of the header-side power supply terminal (23) along the longitudinal direction (X) of the header housing (21) is formed to be wider than the width of the header-side signal terminal (22) along the longitudinal direction (X). Further, the width of the socket-side power supply terminal (33) along the longitudinal direction (X) of the socket housing (31) is formed to be wider than the width of the socket-side signal terminal (32) along the longitudinal direction (X). And according to Patent Document 1, the cross-sectional shape of the socket-side signal terminal (32) and the cross-sectional shape of the socket-side power supply terminal (33) are substantially the same shape, and the cross-sectional shape of the header-side signal terminal (22) and the cross-sectional shape of the header-side power supply terminal (23) are substantially the same shape. However, by making the power supply terminal wider than the signal terminal, the cross-sectional area of the terminal can be increased, so it is said that the current capacity can be increased. Note that the reference numerals related to the description of the prior art document are distinguished from the respective embodiments of the present disclosure by adding parentheses.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-166120 [Summary of the Invention] [Problems to be Solved by the Invention]

[0005] However, in the conventional connector disclosed in Patent Document 1 above, since the current capacity depends on the dimension in the width direction of the power supply terminal, there is a problem that in order to increase the current capacity by increasing the cross-sectional area of the terminal, the size of the connector also increases.

[0006] Therefore, an object of the present disclosure is to provide a connector that can increase the current capacity of a power supply terminal without increasing the size of the connector by realizing a configuration that can increase the current capacity without increasing the dimension in the width direction compared to the power supply terminal of the conventional example. [Means for Solving the Problems]

[0007] The connector according to the present disclosure includes a first connector including a first connector-side signal terminal and a first connector-side power supply terminal aligned in the same column of a first connector housing, and a second connector including a second connector-side signal terminal and a second connector-side power supply terminal aligned in the same column of a second connector housing. By fitting the first connector housing and the second connector housing, the first connector-side signal terminal and the second connector-side signal terminal come into contact with each other, and the first connector-side power supply terminal and the second connector-side power supply terminal come into contact with each other. The first connector-side signal terminal and the first connector-side power supply terminal have a contact portion formed by bending a metal plate into a U shape. The second connector-side signal terminal has a contact portion formed by bending a metal plate into a U shape. The second connector-side power supply terminal has a contact portion formed in an I shape made of a metal plate thicker than the second connector-side signal terminal. When the first connector housing and the second connector housing are fitted, the U-shaped contact portion of the second connector-side signal terminal is sandwiched and contacted by the U-shaped contact portion of the first connector-side signal terminal, and the I-shaped contact portion of the second connector-side power supply terminal is sandwiched and contacted by the U-shaped contact portion of the first connector-side power supply terminal. Further, the height of the second connector-side power supply terminal in the fitting direction is lower than the height of the second connector-side signal terminal in the fitting direction and the height of the resin-made second connector housing. It is characterized by this.

[0008] That is, since the second connector-side power supply terminal has an I-shaped contact portion made of a metal plate thicker than the second connector-side signal terminal, even if the widths of the second connector-side power supply terminal and the second connector-side signal terminal in the alignment direction are the same, the cross-sectional area becomes larger. In addition, since the I-shaped contact portion of the second connector-side power supply terminal is sandwiched and contacted by the U-shaped contact portion of the first connector-side power supply terminal, the current path is shorter than that of the signal terminal in the form where the U-shaped contact portion of the second connector-side signal terminal is sandwiched and contacted by the U-shaped contact portion of the first connector-side signal terminal. That is, compared with the header-side power supply terminal in the conventional example, the second connector-side power supply terminal of the present Disclosure has a shorter current path. Since the current capacity is proportional to the cross-sectional area of the power supply terminal and inversely proportional to the length of the current path, the present one with a large cross-sectional area and a short current path DisclosureIt is possible to increase the current capacity without depending on the dimension in the width direction of the power supply terminal. Also, since the height of the second connector-side power supply terminal in the fitting direction is lower than the height of the second connector-side signal terminal in the fitting direction, when fitting, the signal terminals of the second connector and the first connector come into contact with each other and are aligned, and then the power supply terminals come into contact with each other. Therefore, damage due to collision at a misaligned position is less likely to occur. In particular, in the case of the second connector-side power supply terminal having a contact portion formed in an I-shape made of a metal plate thicker than the second connector-side signal terminal, since the thickness dimension is large, if it collides with the first connector housing, the influence of damage due to the collision is large. However, since the height of the second connector-side power supply terminal in the fitting direction of the present disclosure is lower than the height of the second connector-side signal terminal in the fitting direction, it is possible to prevent damage by contacting the first connector housing.

[0009] Also, in the connector according to the present disclosure, the second connector-side power supply terminal can be formed by bending a metal plate into an L shape as a whole.

[0010] That is, since the second connector-side power supply terminal is formed by bending a metal plate into an L shape as a whole, it has a larger cross-sectional area than the signal terminal over its entire length and is also easy to manufacture.

[0013] Also, in the connector according to the present disclosure, both sides of the second connector-side power supply terminal can be embedded in the longitudinal direction of the second connector housing made of resin.

[0014] That is, since both sides of the second connector-side power supply terminal are embedded in the terminal arrangement direction of the resin-made second connector housing, the second connector-side power supply terminal is less likely to peel off from the second connector housing.

[0015] Also, in the connector according to the present disclosure, the second connector-side power supply terminal can be wider than the second connector-side signal terminal.

[0016] That is, if the second connector-side power supply terminal is wider than the second connector-side signal terminal, the cross-sectional area becomes even larger, so the current capacity can be further increased.

[0017] Another connector according to the present disclosure includes a first connector including a first connector-side signal terminal and a first connector-side power terminal aligned in the same column of the first connector housing, and a second connector including a second connector-side signal terminal and a second connector-side power terminal aligned in the same column of the second connector housing. By fitting the first connector housing and the second connector housing, the first connector-side signal terminal and the second connector-side signal terminal come into contact with each other, and the first connector-side power terminal and the second connector-side power terminal come into contact with each other. The first connector-side signal terminal and the first connector-side power terminal have a contact portion formed by bending a metal plate into a U shape. The second connector-side signal terminal has a contact portion formed by bending a metal plate into a U shape. The second connector-side power terminal has a contact portion formed in an I shape made of a metal plate thicker than the second connector-side signal terminal. When the first connector housing and the second connector housing are fitted, the U-shaped contact portion of the second connector-side signal terminal is sandwiched between and contacts the U-shaped contact portion of the first connector-side signal terminal, and the I-shaped contact portion of the second connector-side power terminal is sandwiched between and contacts the U-shaped contact portion of the first connector-side power terminal. The height of the second connector-side power supply terminal in the fitting direction is lower than the height of the second connector-side signal terminal in the fitting direction and the height of the resin-made second connector housing. The second connector-side power terminal is characterized in that it is formed by bending a metal plate into an L shape as a whole and has at least one notch.

[0018] That is, since the second connector-side power terminal has an I-shaped contact portion made of a metal plate thicker than the second connector-side signal terminal, even if the widths of the second connector-side power terminal and the second connector-side signal terminal in the alignment direction are the same, the cross-sectional area is larger. Also, since the I-shaped contact portion of the second connector-side power terminal is sandwiched between and contacts the U-shaped contact portion of the first connector-side power terminal, the current path is shorter than that of the signal terminal in the form where the U-shaped contact portion of the second connector-side signal terminal is sandwiched between and contacts the U-shaped contact portion of the first connector-side signal terminal. That is, compared with the header-side power terminal in the conventional example, this DisclosureThe second connector-side power supply terminal has a shorter current path. Since the current capacity is proportional to the cross-sectional area of the power supply terminal and inversely proportional to the length of the current path, this Disclosure can increase the current capacity without depending on the dimension in the width direction of the power supply terminal.

[0019] Also, in another connector according to the present disclosure, the notch can be a through hole or a through groove that penetrates in the thickness direction of a metal plate that is bent in an L shape to form the second connector-side power supply terminal.

[0020] That is, since the second connector-side power supply terminal is formed by bending a metal plate into an L shape, it has a larger cross-sectional area than the signal terminal over its entire length and is also easy to manufacture.

[0021] Also, in another connector according to the present disclosure, at least a part of the resin material constituting at least a part of the second connector housing can be filled in the notch.

[0022] That is, when trying to make the second connector-side power supply terminal longer horizontally to cope with an increase in current, it is assumed that the strength of the resin-made second connector housing that holds the second connector-side power supply terminal may be insufficient or the molding may be difficult. Therefore, by providing a notch in the second connector-side power supply terminal and filling at least a part of the resin material constituting at least a part of the second connector housing in this notch, the second connector-side power supply terminal and the second connector housing can be firmly connected, and the strength as a connector can be improved.

[0023] Also, in another connector according to the present disclosure, chamfered shape portions are formed at both ends on both sides in the fitting direction of the second connector-side power supply terminal, and at least a part of the chamfered shape portions is embedded in the longitudinal direction of the resin-made second connector housing can be set .

[0024] That is, since both sides of the power supply terminal on the second connector side are embedded in the terminal arrangement direction of the resin second connector housing, it is difficult for the power supply terminal on the second connector side to peel off from the second connector housing. In particular, chamfered portions are formed by removal processing at both ends on both sides in the fitting direction of the power supply terminal on the second connector side, so that manufacturing dimensional errors that inevitably occur in the power supply terminal on the second connector side are removed. When manufacturing the power supply terminal on the second connector side, which is a metal material, to be embedded in the second connector housing, which is a resin material, problems such as the resin material protruding do not occur, and stable manufacturing can be carried out.

Effect of the Invention

[0025] According to the present disclosure, without depending on the dimension in the width direction of the power supply terminal, the cross-sectional area of the power supply terminal can be increased and the current path can be shortened. Therefore, the current capacity can be increased without increasing the dimension in the terminal alignment direction of the connector. That is, according to the present disclosure, it is possible to provide a connector with an increased current capacity of the power supply terminal without increasing the size of the connector.

[0027] Hereinafter, preferred embodiments for carrying out the present disclosure will be described with reference to the drawings. In the drawings, for convenience of explanation, a first direction, a second direction, and a third direction are defined. In this specification, the first direction is the left-right direction. In the drawings, the left-right direction is shown as the X direction. In particular, the rightward direction is the +X direction, and the leftward direction is the -X direction. Also, in this specification, the second direction is the front-back direction. In the drawings, the front-back direction is shown as the Y direction. In particular, the forward direction is the +Y direction, and the backward direction is the -Y direction. Furthermore, in this specification, the third direction is the up-down direction. In the drawings, the up-down direction is shown as the Z direction. In particular, the upward direction is the +Z direction, and the downward direction is the -Z direction. However, the X direction which is the first direction, the Y direction which is the second direction, and the Z direction which is the third direction defined in this specification do not limit the directions when using the connectors in each of the embodiments described below. The connectors in each of the embodiments described below can be used in any direction.

[0028] Also, each of the following embodiments does not limit the invention according to each claim, and not all of the combinations of features described in each of the following embodiments are essential for the solution means of the invention.

[0029] [First Embodiment] As shown in FIGS. 1 to 3, the connector 10 of the first embodiment includes a first connector 100 which is a receptacle connector and a second connector 500 which is a plug connector. The second connector 500 of the first embodiment is fitted to or removed from the first connector 100 by moving up and down along the Z direction which is the third direction.

[0030] Each of the first connector 100 and the second connector 500 of the first embodiment can be fixed to a circuit board or the like (not shown) to establish electrical connection between circuit boards.

[0031] The configuration of the second connector 500 of the first embodiment which is a plug connector is shown in FIGS. 9 to 13.

[0032] As shown in FIGS. 9 and 10, the second connector 500 of the first embodiment has a second connector housing 501 having a substantially rectangular shape when viewed from above and below along the Z direction, which is the third direction. The second connector housing 501 has long sides along the left - right direction along the X direction, which is the first direction, and short sides along the front - rear direction along the Y direction, which is the second direction. That is, the second connector housing 501 has an outer shape with a substantially rectangular shape extending in the left - right direction.

[0033] The second connector housing 501 is composed of a second connector insulator 502 made of a resin material and second connector hold - downs 503 made of a metal material installed at the left and right ends of the second connector insulator 502. The second connector insulator 502 can be composed of insulating resin parts such as engineering plastics, and has the function of mechanically fixing and holding a plurality of terminals, which will be described later, at predetermined positions, and insulating between the terminals to make each conductive path independent. On the other hand, the second connector hold - down 503 is a member that functions as a fixing and reinforcing metal fitting for a circuit board (not shown), and contributes to protecting the fitting surface and improving the robustness.

[0034] A plurality of terminals are installed in the second connector housing 501 described above. As shown in FIGS. 9 and 10, in the second connector housing 501 of the first embodiment, a plurality of terminals are arranged in a row along the left - right direction along the X direction, which is the first direction of the second connector housing 501. Also, in the second connector 500 of the first embodiment, terminal groups are arranged in a total of two rows, one row on the front side and one row on the rear side of the second connector housing 501.

[0035] Specifically describing a plurality of terminals with reference to FIGS. 9 and 10, among the plurality of terminals arranged in alignment on the front side of the second connector housing 501, one second connector side power terminal 510 is arranged at approximately the central position, five second connector side signal terminals 520 are arranged on the right side of the second connector side power terminal 510, and four second connector side signal terminals 520 are arranged on the left side of the second connector side power terminal 510. On the other hand, among the plurality of terminals arranged in alignment on the rear side of the second connector housing 501, one second connector side power terminal 510 is arranged at approximately the central position, four second connector side signal terminals 520 are arranged on the right side of the second connector side power terminal 510, and five second connector side signal terminals 520 are arranged on the left side of the second connector side power terminal 510.

[0036] In addition, in the case of the first embodiment, since the total number of the second connector side signal terminals 520 arranged in alignment in the same column of the second connector housing 501 is odd, the plurality of terminals arranged in one column on the front side of the second connector housing 501 and the plurality of terminals arranged in one column on the rear side are arranged so as to be rotationally symmetric when rotated in the XY plane. By adopting such an arrangement configuration, when the second connector 500 of the first embodiment is fitted with the first connector 100 described later, the front-rear installation direction is not limited, and the orientation during use is not limited. Also, when the total number of the second connector side signal terminals 520 arranged in alignment in the same column of the second connector housing 501 is even, the number of the second connector side signal terminals 520 arranged on the left and right of the second connector side power terminal 510 may be made the same.

[0037] As shown in FIG. 11, the second connector side signal terminal 520 is configured to include a contact portion 521 formed by bending a metal plate into a U shape and a connection portion 522 continuously formed on the U-shaped contact portion 521.

[0038] On the other hand, as shown in FIG. 12, the second connector-side power supply terminal 510 is formed by bending a metal plate thicker than the second connector-side signal terminal 520 into an L shape, and includes a contact portion 511 formed in an I shape and a connection portion 512 continuously formed on the I-shaped contact portion 511. That is, since the second connector-side power supply terminal 510 is formed by bending a metal plate into an L shape, it has a larger cross-sectional area than the second connector-side signal terminal 520 over its entire length, and is also easy to manufacture.

[0039] Also, as shown in FIGS. 10 and 13, in the first embodiment, the height of the second connector-side power supply terminal 510 in the fitting direction (the vertical direction which is the Z direction) is configured to be lower than the height of the second connector-side signal terminal 520 in the fitting direction (the vertical direction which is the Z direction).

[0040] Also, as shown in FIG. 13, in the first embodiment, both sides of the second connector-side power supply terminal 510 are embedded in the longitudinal direction of a resin second connector housing 501 (more specifically, a second connector insulator 502).

[0041] Furthermore, as shown in FIGS. 9 and 10, the second connector-side power supply terminal 510 of the first embodiment is wider than the second connector-side signal terminal 520.

[0042] As described above, with reference to FIGS. 9 to 13, the configuration of the second connector 500 of the first embodiment, which is a plug connector, has been described. Next, with reference to FIGS. 14 to 17, the configuration of the first connector 100 of the first embodiment, which is a receptacle connector, will be described.

[0043] As shown in FIGS. 14 and 15, the first connector 100 of the first embodiment has a first connector housing 101 having a substantially rectangular shape when viewed from above and below along the Z direction, which is the third direction. The first connector housing 101 has long sides in the left-right direction along the X direction, which is the first direction, and short sides in the front-rear direction along the Y direction, which is the second direction. That is, the first connector housing 101 has an external shape with a substantially rectangular shape extending in the left-right direction.

[0044] The first connector housing 101 is composed of a first connector insulator 102 made of a resin material and first connector hold-downs 103 made of a metal material installed at the left and right ends of the first connector insulator 102. The first connector insulator 102 can be composed of insulating resin parts such as engineering plastics, and has the function of mechanically fixing and holding a plurality of terminals described later at predetermined positions and insulating between the terminals to make each conductive path independent. On the other hand, the first connector hold-down 103 is a member that functions as a fixing and reinforcing metal fitting for a circuit board (not shown), and contributes to protecting the fitting surface and improving the robustness.

[0045] A plurality of terminals are installed in the first connector housing 101 described above. As shown in FIGS. 14 and 15, in the first connector housing 101 of the first embodiment, a plurality of terminals are arranged in a row in the left-right direction along the X direction, which is the first direction of the first connector housing 101. Also, in the first connector 100 of the first embodiment, terminal groups aligned in a total of two rows, one row on the front side and one row on the rear side of the first connector housing 101, are arranged.

[0046] Specifically explaining a plurality of terminals with reference to FIGS. 14 and 15, for the plurality of terminals arranged in alignment on the front side of the first connector housing 101, one first connector-side power terminal 110 is arranged at approximately the central position, five first connector-side signal terminals 120 are arranged on the right side of the first connector-side power terminal 110, and four first connector-side signal terminals 120 are arranged on the left side of the first connector-side power terminal 110. On the other hand, for the plurality of terminals arranged in alignment on the rear side of the first connector housing 101, one first connector-side power terminal 110 is arranged at approximately the central position, four first connector-side signal terminals 120 are arranged on the right side of the first connector-side power terminal 110, and five first connector-side signal terminals 120 are arranged on the left side of the first connector-side power terminal 110.

[0047] In addition, in the case of the first embodiment, since the total number of the first connector-side signal terminals 120 arranged in alignment in the same column of the first connector housing 101 is odd, the plurality of terminals arranged in one column on the front side of the first connector housing 101 and the plurality of terminals arranged in one column on the rear side are arranged so as to be rotationally symmetric when rotated in the XY plane. By adopting such an arrangement configuration, when the second connector 500 described later is fitted into the first connector 100 of the first embodiment, the front-rear installation direction is not limited, and the orientation during use is not limited. Also, when the total number of the first connector-side signal terminals 120 arranged in alignment in the same column of the first connector housing 101 is even, the number of the first connector-side signal terminals 120 arranged on the left and right sides of the first connector-side power terminal 110 may be the same.

[0048] As shown in FIG. 16, the first connector-side signal terminal 120 includes a contact portion 121 formed by bending a metal plate into a U shape, and a connection portion 122 formed continuously with the U-shaped contact portion 121.

[0049] Also, as shown in FIG. 17, the first connector-side power supply terminal 110 is configured to have a contact portion 111 formed by bending a metal plate into a U shape, similar to the first connector-side signal terminal 120, and a connection portion 112 continuously formed on the U-shaped contact portion 111.

[0050] As described above, with reference to FIGS. 14 to 17, the configuration of the first connector 100 of the first embodiment, which is a receptacle connector, has been described.

[0051] As described above, the connector 10 of the first embodiment includes the first connector 100 including the first connector-side signal terminal 120 and the first connector-side power supply terminal 110 aligned in the same row of the first connector housing 101, and the second connector 500 including the second connector-side signal terminal 520 and the second connector-side power supply terminal 510 aligned in the same row of the second connector housing 501. Therefore, by fitting the first connector housing 101 and the second connector housing 501, the first connector-side signal terminal 120 and the second connector-side signal terminal 520 come into contact with each other, and the first connector-side power supply terminal 110 and the second connector-side power supply terminal 510 come into contact with each other (see FIGS. 7 and 8).

[0052] When the first connector housing 101 and the second connector housing 501 are fitted, as shown in FIG. 7, the U-shaped contact portion 521 of the second connector-side signal terminal 520 is sandwiched and contacted by the U-shaped contact portion 121 of the first connector-side signal terminal 120, and as shown in FIG. 8, the I-shaped contact portion 511 of the second connector-side power supply terminal 510 is sandwiched and contacted by the U-shaped contact portion 111 of the first connector-side power supply terminal 110.

[0053] Therefore, since the second connector-side power supply terminal 510 has an I-shaped contact portion 511 made of a metal plate thicker than the second connector-side signal terminal 520, even if the widths of the second connector-side power supply terminal 510 and the second connector-side signal terminal 520 in the alignment direction are the same, the cross-sectional area becomes larger.

[0054] Also, in the first embodiment, as shown in the sub - figure (b) of FIG. 18, the I - shaped contact portion 511 of the second - connector - side power - supply terminal 510 is sandwiched and contacted by the U - shaped contact portion 111 of the first - connector - side power - supply terminal 110. Therefore, compared with the signal - use terminals 120 and 520 in the form where the U - shaped contact portion 521 of the second - connector - side signal - use terminal 520 is sandwiched and contacted by the U - shaped contact portion 121 of the first - connector - side signal - use terminal 120 as shown in the sub - figure (a) of FIG. 18, the current path becomes shorter (refer to the arrows in FIGS. 18(a) and (b)). That is, compared with the header - side power - supply terminal of the conventional example, the second - connector - side power - supply terminal 510 of the first embodiment has a shorter current path. Since the current capacity is proportional to the cross - sectional area of the power - supply terminal and inversely proportional to the length of the current path, the first embodiment with a large cross - sectional area and a short current path has the effect of being able to increase the current capacity without depending on the dimension in the width direction (the left - right direction which is the X direction) of the power - supply terminal.

[0055] Also, as shown in FIGS. 10 and 13, in the connector 10 of the first embodiment, the height of the second - connector - side power - supply terminal 510 in the fitting direction is lower than the height of the second - connector - side signal - use terminal 520 in the fitting direction.

[0056] That is, since the height in the fitting direction of the second connector side power supply terminal 510 is lower than the height in the fitting direction of the second connector side signal terminal 520, when fitting, first, the signal terminals 120 and 520 of the second connector 500 and the first connector 100 come into contact with each other and are aligned, and then the power supply terminals 110 and 510 come into contact with each other. Therefore, in the connector 10 of the first embodiment, damage due to collision at a misaligned position is less likely to occur. In particular, in the case of the second connector side power supply terminal 510 having the contact portion 511 formed in an I shape made of a metal plate thicker than the contact portion 521 of the second connector side signal terminal 520, because the thickness dimension is large, if it collides with the first connector housing 101, the influence of damage due to the collision is large. However, since the height in the fitting direction of the second connector side power supply terminal 510 of the first embodiment is lower than the height in the fitting direction of the second connector side signal terminal 520, it is possible to prevent the second connector side power supply terminal 510 from contacting the first connector housing 101 and being damaged.

[0057] Furthermore, as shown in the sub-diagrams (a1) and (a2) in FIG. 19, if the height in the fitting direction of the second connector side power supply terminal 510 is the same as the height in the fitting direction of the second connector side signal terminal 520, and the positions of the first connector 100 and the second connector 500 are misaligned during fitting, the second connector side power supply terminal 510 with a large thickness dimension may collide with the first connector housing 101, and there is also a risk that the resin-made first connector housing 101 will be damaged. However, as in the first embodiment shown in the sub-diagrams (b1) and (b2) in FIG. 19, when the height in the fitting direction of the second connector side power supply terminal 510 is lower than the height in the fitting direction of the second connector side signal terminal 520, even if the positions of the first connector 100 and the second connector 500 are misaligned during fitting, the first to come into contact are the resin-made first connector housing 101 and the second connector housing 501, so the risk of damage occurring is significantly reduced.

[0058] Also, as shown in FIG. 13, in the connector 10 of the first embodiment, both sides of the second connector side power supply terminal 510 are embedded in the longitudinal direction of the resin-made second connector housing 501. That is, both sides of the second connector side power supply terminal 510 are embedded in the terminal arrangement direction of the resin-made second connector housing 501. Therefore, in the first embodiment, the second connector side power supply terminal 510 is configured to be difficult to peel off from the second connector housing 501.

[0059] Also, as shown in FIGS. 9 and 10 etc., in the connector 10 of the first embodiment, the second connector side power supply terminal 510 has a wider dimension in the left-right direction which is the X direction than the second connector side signal terminal 520. That is, since the second connector side power supply terminal 510 is wider than the second connector side signal terminal 520, the cross-sectional area is further increased, and the current capacity can be further increased. This configuration is preferably applied within a range where the overall shape dimensions of the connector 10 are acceptable, that is, within a range where an increase in the size of the connector 10 is acceptable.

[0060] As described above, the preferred embodiments of the present disclosure have been described, but the technical scope of the present disclosure is not limited to the scope described in the above first embodiment. Various changes or improvements can be made to the above first embodiment.

[0061] For example, in the above-described first embodiment, as shown in the sub-diagram (b) in FIG. 18, the I-shaped contact portion 511 of the second connector side power supply terminal 510 was configured to be sandwiched and contacted by the U-shaped contact portion 111 of the first connector side power supply terminal 110. At this time, in the above-described first embodiment, it was assumed that both the front and rear wall surfaces of the I-shaped contact portion 511 of the second connector side power supply terminal 510 would contact the U-shaped contact portion 111 of the first connector side power supply terminal 110. However, this DisclosureIn that case, it is sufficient that the I-shaped contact portion 511 of the second connector side power supply terminal 510 and the U-shaped contact portion 111 of the first connector side power supply terminal 110 are in contact with each other at least partially and in such a way that the current path is the shortest. That is, in this Disclosure case, the I-shaped contact portion 511 of the second connector side power supply terminal 510 and the U-shaped contact portion 111 of the first connector side power supply terminal 110 only need to be in contact with each other on the left wall surface of the partial view (b) in FIG. 18.

[0062] Also, for example, in the above-described first embodiment, the first connector 100 was described as a receptacle connector and the second connector 500 as a plug connector. However, in the present disclosure, the side having the configuration of the first connector 100 may be a plug connector, and the side having the configuration of the second connector 500 may be a receptacle connector.

[0063] It is clear from the description of the claims that forms with such modifications or improvements added can also be included in the technical scope of the present invention.

[0064] [Second Embodiment] Next, a connector 60 according to a second embodiment, which is another exemplary form obtained by improving the above-described first embodiment, will be described.

[0065] As shown in FIGS. 20 to 22, the connector 60 of the second embodiment includes a first connector 600 that is a receptacle connector and a second connector 700 that is a plug connector. The second connector 700 of the second embodiment is fitted to or removed from the first connector 600 by being moved up and down along the Z direction, which is the third direction.

[0066] Each of the first connector 600 and the second connector 700 of the second embodiment can be fixed to a circuit board or the like (not shown) to establish electrical connection between the circuit boards.

[0067] The configuration of the second connector 700 of the second embodiment, which is a plug connector, is shown in FIGS. 29 to 36.

[0068] As shown in FIGS. 29 and 30, the second connector 700 of the second embodiment has a second connector housing 701 having a substantially rectangular shape when viewed from above and below along the Z direction, which is the third direction. The second connector housing 701 has long sides in the left-right direction along the X direction, which is the first direction, and short sides in the front-rear direction along the Y direction, which is the second direction. That is, the second connector housing 701 has an externally visible shape of a substantially rectangular shape extending in the left-right direction.

[0069] The second connector housing 701 is composed of a second connector insulator 702 made of a resin material and second connector hold-downs 703 made of a metal material installed at the left and right ends of the second connector insulator 702. The second connector insulator 702 can be composed of insulating resin parts such as engineering plastics, and mechanically fixes and holds a plurality of terminals described later at predetermined positions, and has a function of insulating between the terminals to make each conductive path independent. On the other hand, the second connector hold-down 703 is a member that functions as a fixing and reinforcing metal fitting for a circuit board (not shown), and contributes to protecting the mating surface and improving the robustness.

[0070] A plurality of terminals are installed in the second connector housing 701 described above. As shown in FIGS. 29 and 30, in the second connector housing 701 of the second embodiment, three terminals are arranged in each column so as to form a column in the left-right direction along the X direction, which is the first direction of the second connector housing 701. That is, in the second connector 700 of the second embodiment, a total of two rows of six aligned terminal groups, three in one row on the front side and three in one row on the rear side of the second connector housing 701, are arranged.

[0071] Specifically describing a plurality of terminals with reference to FIGS. 29 and 30, among the three terminals arranged in alignment on the front side of the second connector housing 701, one second connector side power supply terminal 710 is arranged at the central position, one second connector side signal terminal 720 is arranged on the right side of the second connector side power supply terminal 710, and one second connector side signal terminal 720 is arranged on the left side of the second connector side power supply terminal 710. On the other hand, among the three terminals arranged in alignment on the rear side of the second connector housing 701, one second connector side power supply terminal 710 is arranged at the central position, one second connector side signal terminal 720 is arranged on the right side of the second connector side power supply terminal 710, and one second connector side signal terminal 720 is arranged on the left side of the second connector side power supply terminal 710.

[0072] In the case of the second embodiment, since the total number of the second connector side signal terminals 720 arranged in alignment in the same column of the second connector housing 701 is an even number, by making the number of the second connector side signal terminals 720 arranged on the left and right sides of the second connector side power supply terminal 710 the same, when the second connector 700 of the second embodiment is fitted with the first connector 600 described later, the front and rear installation directions are not limited, and the orientation during use is not limited. If, by chance, the total number of the second connector side signal terminals 720 arranged in alignment in the same column of the second connector housing 701 is an odd number, they may be arranged so as to be rotationally symmetric when rotated in the XY plane. By adopting such an arrangement configuration, when fitted with the first connector 600 described later, the front and rear installation directions are not limited, and the orientation during use is not limited.

[0073] As shown in FIG. 34, the second connector side signal terminal 720 is configured to include a contact portion 721 formed by bending a metal plate into a U shape and a connection portion 722 formed continuously with the U-shaped contact portion 721.

[0074] On the other hand, as shown in FIG. 35, the second connector-side power supply terminal 710 is formed by bending a metal plate thicker than the second connector-side signal terminal 720 into an L shape, and includes a contact portion 711 formed in an I shape and a connection portion 712 continuously formed on the contact portion 711 having an I shape. That is, since the second connector-side power supply terminal 710 is formed by bending a metal plate into an L shape, it has a larger cross-sectional area than the second connector-side signal terminal 720 over its entire length, and is also easy to manufacture.

[0075] Also, as shown in FIG. 35, the second connector-side power supply terminal 710 has two notches 713 at positions near the curved portion where the metal plate is bent into an L shape. The notch 713 of the second embodiment is formed as a through hole that penetrates in the thickness direction of the metal plate that is bent into an L shape to form the second connector-side power supply terminal 710. Then, as shown in FIGS. 33 and 36, a part of the second connector insulator 702 made of a resin material that constitutes the second connector housing 701 is filled in the notch 713.

[0076] Here, when attempting to make the second connector-side power supply terminal 710 longer in the horizontal (left-right direction) to cope with an increase in current, it is assumed that the strength of the second connector housing 701 including the resin second connector insulator 702 that holds the second connector-side power supply terminal 710 may be insufficient or molding may be difficult. Therefore, in the second embodiment, a notch 713 formed as a through hole is provided in the second connector-side power supply terminal 710, and a resin material (a part of the second connector insulator 702) that constitutes at least a part of the second connector housing 701 is filled in this notch 713. By adopting such a configuration, a strong connection state between the second connector housing 701 and the second connector-side power supply terminal 710 is realized, and the strength of the entire connector 60 is also improved.

[0077] Further, as shown in FIG. 35, chamfered shape portions 714 are formed by removal processing at both end portions on both sides in the fitting direction of the second connector side power supply terminal 710. The chamfered shape portions 714 have a shape in which both end portions on both sides in the fitting direction are chamfered into an R shape, and the shape can be formed by removal processing using a conventionally known removal processing technique such as press processing, turning processing, grinding processing, polishing processing, or the like.

[0078] Then, as shown in FIG. 36, at least a part of the chamfered shape portion 714 formed by removal processing is embedded in the longitudinal direction of the second connector housing 701 (more specifically, the second connector insulator 702) made of resin. That is, since both sides of the second connector side power supply terminal 710 are embedded in the terminal arrangement direction of the resin-made second connector housing 701, the second connector side power supply terminal 710 is less likely to peel off from the second connector housing 701. In particular, by forming the chamfered shape portions 714 by removal processing at both end portions on both sides in the fitting direction of the second connector side power supply terminal 710, it is possible to remove manufacturing dimensional errors that inevitably occur in the second connector side power supply terminal 710 whose overall shape is formed by bending a thick metal plate into an L shape. As a result, when manufacturing the second connector side power supply terminal 710 made of a metal material to be embedded in the second connector housing 701 (more specifically, the second connector insulator 702) made of a resin material, problems such as the resin material overflowing do not occur, and stable manufacturing can be carried out.

[0079] Also, as shown in FIG. 31 (or as is clear by comparing FIGS. 26 and 27 with FIG. 28), in the second embodiment, the height of the second connector side power supply terminal 710 in the fitting direction (the vertical direction which is the Z direction) is configured to be lower than the height of the second connector side signal terminal 720 in the fitting direction (the vertical direction which is the Z direction).

[0080] Furthermore, as shown in FIGS. 9 and 10, the second connector-side power supply terminal 710 of the second embodiment is wider than the second connector-side signal terminal 720.

[0081] As described above, with reference to FIGS. 29 to 36, the configuration of the second connector 700 of the second embodiment, which is a plug connector, has been described. Next, with reference to FIGS. 38 to 41, the configuration of the first connector 600 of the second embodiment, which is a receptacle connector, will be described.

[0082] As shown in FIGS. 38 and 39, the first connector 600 of the second embodiment has a first connector housing 601 having a substantially rectangular shape when viewed from above and below along the Z direction, which is the third direction. The first connector housing 601 has long sides in the left-right direction along the X direction, which is the first direction, and short sides in the front-rear direction along the Y direction, which is the second direction. That is, the first connector housing 601 has an outer shape with a substantially rectangular shape extending in the left-right direction.

[0083] The first connector housing 601 is composed of a first connector insulator 602 made of a resin material and first connector hold-downs 603 made of a metal material installed at the left and right ends of the first connector insulator 602. The first connector insulator 602 can be composed of insulating resin parts such as engineering plastics, and has the function of mechanically fixing and holding a plurality of terminals described later at predetermined positions and insulating between the terminals to make each conductive path independent. On the other hand, the first connector hold-down 603 is a member that functions as a fixing and reinforcing metal fitting for a circuit board (not shown), and contributes to protecting the fitting surface and improving the robustness.

[0084] A plurality of terminals are installed in the above-described first connector housing 601. As shown in FIGS. 38 and 39, in the first connector housing 601 of the second embodiment, three terminals are arranged in each column so as to form a row in the left-right direction along the X direction, which is the first direction of the first connector housing 601. That is, in the first connector 600 of the second embodiment, a total of two rows of six aligned terminal groups are arranged, with three in one row on the front side and three in one row on the rear side of the first connector housing 601.

[0085] Specifically explaining the plurality of terminals with reference to FIGS. 38 and 39, among the plurality of terminals arranged in alignment on the front side of the first connector housing 601, one first connector side power supply terminal 610 is arranged at the central position, one first connector side signal terminal 620 is arranged on the right side of the first connector side power supply terminal 610, and one first connector side signal terminal 620 is arranged on the left side of the first connector side power supply terminal 610. On the other hand, among the plurality of terminals arranged in alignment on the rear side of the first connector housing 601, one first connector side power supply terminal 610 is arranged at the central position, one first connector side signal terminal 620 is arranged on the right side of the first connector side power supply terminal 610, and one first connector side signal terminal 620 is arranged on the left side of the first connector side power supply terminal 610.

[0086] In the case of the second embodiment, since the total number of the first connector side signal terminals 620 arranged in the same column of the first connector housing 601 is an even number, the number of the first connector side signal terminals 620 arranged on the left and right of the first connector side power supply terminal 610 is the same. When the second connector 700 is fitted to the first connector 600, the front-back installation direction is not limited, and the orientation during use is not limited. On the other hand, when the total number of the first connector side signal terminals 620 aligned in the same column of the first connector housing 601 is an odd number, the plurality of terminals arranged in one row on the front side of the first connector housing 601 and the plurality of terminals arranged in one row on the rear side may be arranged so as to be rotationally symmetric when rotated in the XY plane. By adopting such an arrangement configuration, when the second connector 700 is fitted to the first connector 600 of the second embodiment, the front-back installation direction is not limited, and the orientation during use is not limited.

[0087] As shown in FIG. 40, the first connector side signal terminal 620 includes a contact portion 621 formed by bending a metal plate into a U shape, and a connection portion 622 formed continuously with the U-shaped contact portion 621.

[0088] Also, as shown in FIG. 41, the first connector side power supply terminal 610 is configured to include a contact portion 611 formed by bending a metal plate into a U shape, and a connection portion 612 formed continuously with the U-shaped contact portion 611, similar to the first connector side signal terminal 620.

[0089] As described above, with reference to FIGS. 38 to 41, the configuration of the first connector 600 of the second embodiment, which is a receptacle connector, has been described.

[0090] As described above, the connector 60 of the second embodiment includes a first connector 600 including a first connector-side signal terminal 620 and a first connector-side power supply terminal 610 aligned in the same column of the first connector housing 601, and a second connector 700 including a second connector-side signal terminal 720 and a second connector-side power supply terminal 710 aligned in the same column of the second connector housing 701. Therefore, by fitting the first connector housing 601 and the second connector housing 701, the first connector-side signal terminal 620 and the second connector-side signal terminal 720 come into contact with each other, and the first connector-side power supply terminal 610 and the second connector-side power supply terminal 710 come into contact with each other (see FIGS. 26 to 28).

[0091] When the first connector housing 601 and the second connector housing 701 are fitted, as shown in FIG. 28, the U-shaped contact portion 721 of the second connector-side signal terminal 720 is sandwiched and contacts the U-shaped contact portion 621 of the first connector-side signal terminal 620, and as shown in FIGS. 26 and 27, the I-shaped contact portion 711 of the second connector-side power supply terminal 710 is sandwiched and contacts the U-shaped contact portion 611 of the first connector-side power supply terminal 610.

[0092] Therefore, since the second connector-side power supply terminal 710 has an I-shaped contact portion 711 made of a metal plate thicker than the second connector-side signal terminal 720, even if the widths of the second connector-side power supply terminal 710 and the second connector-side signal terminal 720 in the alignment direction are the same, the cross-sectional area is larger.

[0093] In the second embodiment, in order to cope with an increase in current, the second connector-side power supply terminal 710 is made longer in the horizontal (left-right direction). In the second connector-side power supply terminal 710 of the second embodiment, a notch portion 713 formed as a through hole is provided, and at least a part of the resin material (a part of the second connector insulator 702) constituting at least a part of the second connector housing 701 is filled in the notch portion 713. Therefore, a strong connection state between the second connector housing 701 and the second connector-side power supply terminal 710 is realized, and the strength of the entire connector 60 is also improved.

[0094] Also, as shown in FIG. 36, in the connector 60 of the second embodiment, both sides of the second connector-side power supply terminal 710 are embedded in the longitudinal direction of the resin second connector housing 701. That is, both sides of the second connector-side power supply terminal 710 are embedded in the terminal arrangement direction of the resin second connector housing 701. Therefore, in the second embodiment, the second connector-side power supply terminal 710 is configured to be difficult to peel off from the second connector housing 701.

[0095] In particular, in the second embodiment, chamfered shape portions 714 are formed by removal processing at both end portions on both sides in the fitting direction of the second connector-side power supply terminal 710. Therefore, manufacturing dimensional errors that inevitably occur in the second connector-side power supply terminal 710 whose overall shape is formed by bending a thick metal plate into an L shape can be removed. As a result, when manufacturing the second connector-side power supply terminal 710 made of a metal material to be embedded in the second connector housing 701 made of a resin material (more specifically, the second connector insulator 702), problems such as the resin material protruding do not occur, and stable manufacturing can be carried out.

[0096] Also, as shown in FIG. 31 (or as is clear by comparing FIGS. 26 and 27 with FIG. 28), in the connector 60 of the second embodiment, the height of the second connector-side power supply terminal 710 in the fitting direction is lower than the height of the second connector-side signal terminal 720 in the fitting direction.

[0097] That is, since the height in the fitting direction of the second connector side power supply terminal 710 is lower than the height in the fitting direction of the second connector side signal terminal 720, when fitting, first, the signal terminals 620 and 720 of the second connector 700 and the first connector 600 come into contact with each other and are aligned, and then the power supply terminals 610 and 710 come into contact with each other. Therefore, in the connector 60 of the second embodiment, damage due to collision at a misaligned position is less likely to occur. In particular, in the case of the second connector side power supply terminal 710 having a contact portion 711 formed in an I shape made of a metal plate thicker than the contact portion 721 of the second connector side signal terminal 720, since the thickness dimension is large, if it collides with the first connector housing 601, the influence of damage due to the collision is large. However, since the height in the fitting direction of the second connector side power supply terminal 710 of the second embodiment is lower than the height in the fitting direction of the second connector side signal terminal 720, it is possible to prevent the second connector side power supply terminal 710 from coming into contact with the first connector housing 601 and being damaged.

[0098] Also, as shown in FIGS. 29 and 30 and the like, in the connector 60 of the second embodiment, the second connector side power supply terminal 710 has a wider dimension in the left-right direction, which is the X direction, than the second connector side signal terminal 720. That is, since the second connector side power supply terminal 710 is wider than the second connector side signal terminal 720, the cross-sectional area is further increased, and the current capacity can be further increased. This configuration is preferably applied within the range where the overall shape dimensions of the connector 60 can be tolerated, that is, within the range where an increase in the size of the connector 60 can be tolerated.

[0099] As described above, the preferred embodiments of the present disclosure have been described. However, the technical scope of the present disclosure is not limited to the scope described in the above second embodiment. Various changes or improvements can be made to the above second embodiment.

[0100] For example, in the above-described second embodiment, the notch portion 713 formed in the second connector-side power supply terminal 710 was formed as a through hole that penetrates in the thickness direction of the metal plate. However, regarding the notch portion of the present disclosure, for example, as shown in FIG. 37, it may be a notch portion 713a formed as a through groove that penetrates in the thickness direction of the metal plate that is bent into an L shape to form the second connector-side power supply terminal 710 as a whole. That is, the notch portion of the present disclosure may have any shape as long as a strong connection state between the second connector housing 701 and the second connector-side power supply terminal 710 is realized. It may be a notch portion 713 formed as a closed through hole as shown in FIG. 35, or a notch portion 713a formed as an open through groove as shown in FIG. 37.

[0101] Also, for example, in the above-described second embodiment, the first connector 600 was described as a receptacle connector and the second connector 700 as a plug connector. However, in the present disclosure, the side having the configuration of the first connector 600 may be a plug connector, and the side having the configuration of the second connector 700 may be a receptacle connector.

[0102] It is clear from the description of the claims that forms with such modifications or improvements added may also be included in the technical scope of the present invention.
