[0017] (Description of embodiments of the present invention)

[0018] First, embodiments of the present invention will be described.

[0019] (1) The terminal of the present invention comprises: a terminal body having a busbar fastening portion for bolting to a busbar; and a spring member having a spring sheet that contacts a counterpart terminal and engages with the terminal body, the terminal body comprising: a first mounting piece extending from the end of the busbar fastening portion in a first direction orthogonal to the bolt axis, i.e., a first end; and a second mounting piece extending from the end of the busbar fastening portion in a second direction opposite to the first direction, i.e., a second end, in a manner opposite to the first mounting piece, the spring member being assembled between the first mounting piece and the second mounting piece and engaging with the first mounting piece and the second mounting piece respectively.

[0020] According to this structure, the current from the opposite terminal in contact with the spring sheet of the spring member flows separately from the spring member to the first assembly piece and the second assembly piece. Furthermore, the current flowing through the first assembly piece and the current flowing through the second assembly piece merge at the busbar fastening portion and flow to the busbar. That is, the current flowing through the first assembly piece and the current flowing through the second assembly piece are configured so that they do not merge before reaching the busbar fastening portion where they are bolted to the busbar. Therefore, the localized increase in heat generation caused by the current flowing through the first assembly piece and the current flowing through the second assembly piece merging before reaching the busbar fastening portion is prevented, and as a result, heat generation from the terminal body can be suppressed.

[0021] (2) In (1) above, the first assembly piece and the second assembly piece in the terminal body can also be integrally formed with the busbar fastening part by bending.

[0022] According to this structure, the first assembly piece and the second assembly piece can be easily formed. Furthermore, the unfolded shape of the terminal body, including the busbar fastener, the first assembly piece, and the second assembly piece, can be simplified. Therefore, when the terminal body is formed from a sheet material through punching, the punching waste loss of the sheet material can be minimized.

[0023] (3) In (2) above, the first assembly piece and the second assembly piece may have a first configuration portion and a second configuration portion respectively, the spring member is disposed between the first configuration portion and the second configuration portion, the first assembly piece has a first bending portion formed by bending a portion from the first end to the first configuration portion, and the second assembly piece has a second bending portion formed by bending a portion from the second end to the second configuration portion.

[0024] According to this structure, the rigidity of the first and second assembly pieces can be improved relative to the torque generated during bolt tightening at the busbar fastening part by means of the first and second bending portions, respectively. This suppresses deformation of the first and second assembly pieces during bolt tightening.

[0025] (4) In (3) above, the first assembly piece may have a first inclined portion that is inclined from the first bent portion toward the first end toward the first direction, and the second assembly piece may have a second inclined portion that is inclined from the second bent portion toward the second end toward the second direction.

[0026] According to this structure, the first inclined portion of the first assembly piece and the second inclined portion of the second assembly piece are inclined in such a way that they extend outwards as they move towards the busbar fastening portion. As a result, space can be ensured between the first inclined portion and the second inclined portion, which, for example, makes it easy to ensure the placement space of the nut in the busbar fastening portion.

[0027] (5) The connector of the present invention comprises: a terminal as described in any one of (1) to (4) above; and a housing having a cavity for receiving the terminal.

[0028] According to this structure, the current from the opposite terminal in contact with the spring sheet of the spring member flows separately from the spring member to the first assembly piece and the second assembly piece. Furthermore, the current flowing through the first assembly piece and the current flowing through the second assembly piece merge at the busbar fastening portion and flow to the busbar. That is, the current flowing through the first assembly piece and the current flowing through the second assembly piece are configured so that they do not merge before reaching the busbar fastening portion where they are bolted to the busbar. Therefore, the localized increase in heat generation caused by the current flowing through the first assembly piece and the current flowing through the second assembly piece merging before reaching the busbar fastening portion is prevented, and as a result, heat generation from the terminal body can be suppressed.

[0032] (Structure of connector 10)

[0033] like Figure 1 and Figure 2As shown, connector 10 includes a housing 11 and terminals 12 housed within the housing 11. Connector 10 is, for example, a high-voltage connector capable of handling high voltage / high current. Connector 10 is mated with a counterpart connector (not shown). Terminals 12 of connector 10 are electrically connected to counterpart terminals T of the counterpart connector.

[0034] The connector 10, for example, has a plurality of terminals 12 (three in this embodiment). The plurality of terminals 12 are arranged in the width direction (Y-axis direction). Each of the plurality of terminals 12 is electrically connected to a separate counterparty terminal T. Figure 1 As shown, an opening 13 is provided on the front X1 side end face of the housing 11, and the counterpart terminal T is inserted into the opening 13 with the rear X2 facing outward. There are three openings 13 corresponding to the number of terminals 12. Each counterpart terminal T is inserted into the corresponding terminal 12 inside the housing 11.

[0035] (Structure of shell 11)

[0036] like Figure 2 As shown, the housing 11 includes a main body 15 and a fixing part 16 integrally formed with the main body 15, and the main body 15 has a cavity 14 inside. The housing 11 is formed, for example, from synthetic resin. It should be noted that... Figure 2 This shows the state with one of the multiple terminals 12 removed from the cavity 14. Additionally, Figure 3 yes Figure 2 The 3-3 line cross-sectional view shows the terminal 12 housed in the cavity 14.

[0037] like Figure 2 and Figure 3 As shown, the main body 15 has three cavities 14 corresponding to the number of terminals 12. The cavities 14 are arranged in the width direction (Y-axis direction). Each terminal 12 is housed in its respective cavity 14. Each cavity 14 communicates with the aforementioned openings 13. The opposing terminal T is inserted into the cavity 14 through the opening 13. The terminal 12 is assembled from the rear (X2) end of the cavity 14 towards the front (X1). Figure 3 As shown, cavity 14 has a locking portion 17 protruding into the interior of cavity 14. The locking portion 17 locks onto terminal 12 to prevent terminal 12 from falling off cavity 14 rearward X2.

[0038] like Figure 1 and Figure 2 As shown, the housing 11 includes, for example, a pair of fixing parts 16. The pair of fixing parts 16 extend, for example, from the rear X2 side end of the main body 15 to both sides in the width direction (Y-axis direction). Each fixing part 16 is fastened to, for example, a device housing, which is the fixing object for fixing the connector 10, by bolts.

[0039] (Structure of terminal 12)

[0040] like Figure 3 and Figure 4 As shown, the terminal 12 in this embodiment includes, for example, a terminal body 20, a spring member 50, and a clamping member 60. The terminal body 20, spring member 50, and clamping member 60 are each formed separately. Furthermore, the terminal body 20 and spring member 50 are each formed of a conductor such as metal. The terminal body 20 is integrally formed from a sheet of material with uniform thickness by stamping. The spring member 50 is integrally formed from a sheet of material with uniform thickness that is thinner than the terminal body 20 by stamping. It should be noted that the thickness of the spring member 50 is, for example, set to be less than half the thickness of the terminal body 20.

[0041] (Structure of terminal body 20)

[0042] The terminal body 20 includes a busbar fastening portion 21, a first mounting piece 30, and a second mounting piece 40. As described above, the terminal body 20 is formed from a plate-shaped raw material by stamping, therefore the busbar fastening portion 21, the first mounting piece 30, and the second mounting piece 40 are all plate-shaped.

[0043] (Structure of busbar fastener 21)

[0044] The busbar fastening portion 21 is formed as a plate that is perpendicular to the insertion direction of the counterpart terminal T relative to the terminal 12 (rear X2 in this embodiment). That is, the thickness direction of the busbar fastening portion 21 is consistent with the front-rear direction (X-axis direction).

[0045] like Figure 3 As shown, a through hole 22 is formed in the busbar fastening part 21, extending through the busbar fastening part 21 in the front-rear direction. On the front X1 side surface of the busbar fastening part 21 at a position corresponding to the through hole 22, a nut 23 capable of engaging a bolt B1 is fixed, for example, by welding or pressing. The busbar fastening part 21 is fastened to, for example, a busbar B2 by the bolt B1 and the nut 23. The busbar B2 is, for example, a conductive member disposed within the device housing to which the connector 10 is fixed. The bolt axis L1 of the busbar fastening part 21 extends along the X-axis.

[0046] (Structure of the first assembly piece 30 and the second assembly piece 40)

[0047] like Figure 3 and Figure 4As shown, the first assembly piece 30 extends forward X1 from the first end 21a of the busbar fastening portion 21 in a first direction orthogonal to the bolt axis L1 (Z1 above). The second assembly piece 40 extends forward X1 from the second end 21b of the busbar fastening portion 21 in a second direction opposite to the first direction (Z2 below). The first assembly piece 30 and the second assembly piece 40 are integrally formed with the busbar fastening portion 21 by bending. The first assembly piece 30 and the second assembly piece 40 are formed in a manner that they face each other in the Z-axis direction. The first assembly piece 30 and the second assembly piece 40 have a generally symmetrical shape.

[0048] The first assembly piece 30 and the second assembly piece 40 each have a first mounting portion 31 and a second mounting portion 41, respectively. A spring member 50 is disposed between the first mounting portion 31 and the second mounting portion 41. The first mounting portion 31 and the second mounting portion 41 are, for example, formed as plates perpendicular to the Z-axis direction. The first mounting portion 31 and the second mounting portion 41 are opposite to each other in the Z-axis direction and are, for example, parallel to each other. For example, the second mounting portion 41 has a locking hole 41a, and the locking portion 17 of the housing 11 is locked in the locking hole 41a. The locking portion 17 is locked in the locking hole 41a in a manner that prevents the terminal 12 from falling off the cavity 14 rearward X2.

[0049] The first assembly piece 30 has a first bent portion 32 formed by bending a portion from the first end 21a of the busbar fastening portion 21 to the first placement portion 31. In addition, the first assembly piece 30 has a first inclined portion 33 that is inclined upward Z1 from the first bent portion 32 toward the first end 21a.

[0050] The second assembly piece 40 includes a second bent portion 42 formed by bending a portion from the second end 21b of the busbar fastener 21 to the second placement portion 41. Additionally, the second assembly piece 40 includes a second inclined portion 43 that slopes downwards towards the Z2 side from the second bent portion 42 toward the second end 21b. The first inclined portion 33 and the second inclined portion 43 are opposite each other in the Z-axis direction and are inclined in a manner that extends outwards in the Z-axis direction as they approach the busbar fastener 21. A nut 23, fixed to the back side (front X1 side) of the busbar fastener 21, is disposed between the first inclined portion 33 and the second inclined portion 43.

[0051] As described above, the terminal body 20, including the busbar fastening part 21, the first assembly piece 30, and the second assembly piece 40, is formed, for example, from a strip of raw material punched from a metal sheet into a straight strip shape, and the strip of raw material is bent so that both ends of the long side face the same direction, thereby forming a generally U-shaped shape. In addition, by bending the first assembly piece 30 and the second assembly piece 40 to form the first bend 32 and the second bend 42, respectively, the rigidity relative to the torque generated when the busbar fastening part 21 is bolted can be improved, for example.

[0052] (Structure of spring component 50)

[0053] like Figure 4 As shown, the spring member 50 of terminal 12 includes a pair of sidewall portions 50a facing each other in the Y-axis direction and a plurality of connecting portions 51, 52, 53, and 54 connecting the pair of sidewall portions 50a to each other. In the spring member 50 of this embodiment, the number of the plurality of connecting portions 51, 52, 53, and 54 is, for example, two at the front and two at the back, totaling four, and these are referred to as the first connecting portion 51, the second connecting portion 52, the third connecting portion 53, and the fourth connecting portion 54. Each sidewall portion 50a of the spring member 50 is, for example, a flat plate perpendicular to the Y-axis direction. In addition, each sidewall portion 50a is, for example, approximately quadrilateral when viewed from the Y-axis direction.

[0054] A first connecting portion 51 and a second connecting portion 52 are provided at the rear end (rear x2 end) of the spring member 50. The first connecting portion 51 connects the upper ends of each side wall portion 50a to each other at the rear end of the spring member 50. The second connecting portion 52 connects the lower ends of each side wall portion 50a to each other at the rear end of the spring member 50. A third connecting portion 53 and a fourth connecting portion 54 are provided at the front x1 side compared to the first connecting portion 51 and the second connecting portion 52. The third connecting portion 53 connects the upper ends of each side wall portion 50a to each other. The fourth connecting portion 54 connects the lower ends of each side wall portion 50a to each other.

[0055] like Figure 3 and Figure 4 As shown, the spring member 50 has a counter terminal insertion port 55 at its front end (front X1 end). The counter terminal insertion port 55 is formed by the front ends of a pair of sidewall portions 50a, a third connecting portion 53, and a fourth connecting portion 54. The counter terminal T is inserted into the counter terminal insertion port 55 with the rear X2 facing outwards. The spring member 50 has a clamping member insertion port 56 at its rear end (rear X2 end). The clamping member insertion port 56 is formed by the rear ends of a pair of sidewall portions 50a, a first connecting portion 51, and a second connecting portion 52.

[0056] (Structure of spring sheet 57)

[0057] like Figure 3 As shown, the spring member 50 has, for example, two spring plates 57. The two spring plates 57 extend obliquely from the third connecting portion 53 and the fourth connecting portion 54 toward the rearward X2 side, respectively, in a manner approaching each other. The two spring plates 57 are located between a pair of sidewall portions 50a and are positioned opposite each other in the Z-axis direction. A counter-terminal T, inserted from the counter-terminal insertion port 55 toward the rearward X2 side, is inserted between the two spring plates 57.

[0058] The spring member 50 includes a first stop portion 58 extending from the third connecting portion 53. The first stop portion 58 abuts against the front end portion (front x 1 side end) of the first mounting piece 30 in a rearward x 2 direction. In addition, the spring member 50 includes a second stop portion 59 extending from the fourth connecting portion 54. The second stop portion 59 abuts against the front end portion (front x 1 side end) of the second mounting piece 40 in a rearward x 2 direction.

[0059] The spring member 50 is joined to the first assembly piece 30 and the second assembly piece 40 of the terminal body 20, for example, by laser welding, arc welding, gas welding, spot welding (resistance welding), or ultrasonic welding. Specifically, the third connecting portion 53 of the spring member 50 is joined to a portion near the front end of the first placement portion 31 in the first assembly piece 30. The fourth connecting portion 54 of the spring member 50 is joined to a portion near the front end of the second placement portion 41 in the second assembly piece 40. Thus, the spring member 50 is electrically connected to both the first assembly piece 30 and the second assembly piece 40. Current flows primarily from the spring member 50 to the first assembly piece 30 and the second assembly piece 40 via the aforementioned joining portions. It should be noted that the joining method between the terminal body 20 and the spring member 50 is not limited to the various welding methods described above; mortise and tenon joints, etc., can also be used.

[0060] (Structure of clamping component 60)

[0061] like Figure 3 As shown, the clamping member 60 is inserted forward X1 into the clamping member insertion port 56 and is fitted to the top end of a pair of spring plates 57 (here, the rear X2 end). The clamping member 60 applies a pressing force to the pair of spring plates 57 in a direction that brings them closer together. The clamping member 60 is formed, for example, by stamping a metal sheet. The clamping member 60 is separate from the terminal body 20 and the spring member 50. It should be noted that the clamping member 60 is not a component of the terminal 12 that requires electrical connection. Therefore, the material of the clamping member 60 can be a material that is difficult to conduct electricity or an insulator. The material of the clamping member 60 is, for example, stainless steel.

[0062] The clamping member 60 has a pair of arms 61 that clamp a pair of spring plates 57. The pair of arms 61 are inclined toward each other in a forward X1 direction. The pair of arms 61 exert spring force in the direction of approaching each other. The pair of spring plates 57 facing each other in the Z-axis direction are exerted force toward each other by the elasticity of the clamping member 60. Therefore, even if misalignment occurs in the Z-axis direction between the terminal 12 and the counterpart terminal T due to manufacturing tolerances, the force (contact pressure) of the pair of spring plates 57 clamping the counterpart terminal T in the Z-axis direction is varied as much as possible.

[0063] (The function of this implementation method)

[0064] The function of this embodiment will be explained below.

[0065] The current from the opposing terminal T, which is in contact with each spring piece 57 of the spring member 50, flows separately from the spring member 50 to the first mounting piece 30 and the second mounting piece 40. Furthermore, the current flowing through the first mounting piece 30 and the current flowing through the second mounting piece 40 merge at the busbar fastening portion 21 and flow to the busbar B2. That is, the terminal 12 in this embodiment is structured such that the current flowing through the first mounting piece 30 and the current flowing through the second mounting piece 40 do not merge before reaching the busbar fastening portion 21, which is bolted to the busbar B2. Therefore, the localized increase in heat generation caused by the merging of the currents flowing through the first mounting piece 30 and the second mounting piece 40 before reaching the busbar fastening portion 21 is prevented, and as a result, the heat generated by the terminal body 20 can be suppressed.

[0066] (Effects of this implementation method)

[0067] The effects of this embodiment will be explained below.

[0068] (1) The terminal body 20 of the terminal 12 includes: a first mounting piece 30 extending from the first end 21a of the busbar fastening portion 21; and a second mounting piece 40 extending from the second end 21b of the busbar fastening portion 21 opposite to the first mounting piece 30. A spring member 50 is mounted between the first mounting piece 30 and the second mounting piece 40, and engages with the first mounting piece 30 and the second mounting piece 40 respectively. According to this structure, the local heat generation caused by the current flowing through the first mounting piece 30 and the current flowing through the second mounting piece 40 merging before reaching the busbar fastening portion 21 is not generated, and as a result, the heat generation generated by the terminal body 20 can be suppressed.

[0069] (2) The first assembly piece 30 and the second assembly piece 40 in the terminal body 20 are integrally formed with the busbar fastening part 21 by bending. According to this structure, the first assembly piece 30 and the second assembly piece 40 can be easily formed. In addition, the unfolded shape of the terminal body 20, including the busbar fastening part 21, the first assembly piece 30 and the second assembly piece 40, can be simplified (for example, it can be set as a straight strip). Therefore, when the terminal body 20 is formed from a plate-shaped raw material by punching, the punching waste loss of the plate-shaped raw material can be minimized.

[0070] (3) The first assembly piece 30 and the second assembly piece 40 each have a first placement portion 31 and a second placement portion 41, respectively. The spring member 50 is disposed between the first placement portion 31 and the second placement portion 41. The first assembly piece 30 has a first bent portion 32 formed by bending a portion from the first end 21a to the first placement portion 31. The second assembly piece 40 has a second bent portion 42 formed by bending a portion from the second end 21b to the second placement portion 41. According to this structure, in the first assembly piece 30 and the second assembly piece 40, the rigidity relative to the torque generated when the bolt is tightened at the busbar fastening portion 21 can be improved by the first bent portion 32 and the second bent portion 42, respectively. As a result, deformation of the first assembly piece 30 and the second assembly piece 40 during bolt tightening can be suppressed.

[0071] (4) The first assembly piece 30 has a first inclined portion 33 that slopes from the first bend 32 toward the first end 21a toward the first direction side (here, the upper Z1 side). The second assembly piece 40 has a second inclined portion 43 that slopes from the second bend 42 toward the second end 21b toward the second direction side (here, the lower Z2 side). According to this structure, the first inclined portion 33 of the first assembly piece 30 and the second inclined portion 43 of the second assembly piece 40 are inclined in such a way that they extend outwards towards the busbar fastening portion 21. As a result, space can be ensured between the first inclined portion 33 and the second inclined portion 43, and as a result, for example, space for the nut 23 in the busbar fastening portion 21 can be easily ensured.

[0072] (Other implementation methods)

[0073] The above embodiments can be implemented with the following modifications. The above embodiments and the following variations can be combined with each other within the scope of technical inconsistency.

[0074] In the terminal body 20, the first inclined portion 33 of the first mounting piece 30 may also be inclined downward Z2 toward the first end 21a of the busbar fastening portion 21 from the first bent portion 32. The second inclined portion 43 of the second mounting piece 40 may also be inclined upward Z1 toward the second end 21b of the busbar fastening portion 21 from the second bent portion 42. That is, the first inclined portion 33 and the second inclined portion 43 may also be inclined in such a way that they narrow inward toward the busbar fastening portion 21.
