[0039] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0040] like Figures 1 to 3 As shown, the electrical connector 10 of this embodiment includes a first terminal 1, a second terminal 2, and a conductive element 3. One end of the first terminal 1 forms a first insertion interface 111, and the conductive element 3 is electrically connected to the other end of the first terminal 1. The second terminal 2 is disposed outside the first terminal 1 and contacts the first terminal 1 to provide a clamping force on the first terminal 1.

[0041] When the electrical connector 10 of this embodiment is electrically connected, the conductive element 3 is connected to the corresponding electrical connector, and the accessory is inserted into the first terminal 1 through the first insertion interface 111, thereby realizing the electrical connection between the electrical connector and the accessory through the electrical connector 10. By placing the second terminal 2 on the outside of the first terminal 1, the clamping force of the first terminal 1 provided by the second terminal 2 can be increased, thereby reducing the contact resistance between the electrical connector 10 and the accessory and improving the current carrying capacity of the electrical connector 10.

[0042] Optionally, the rigidity of the second terminal 2 is greater than that of the first terminal 1.

[0043] When connecting the accessory to the electrical connector 10, the first terminal 1 needs to undergo elastic deformation so that the accessory can be inserted into the first terminal 1 through the first insertion interface 111. The second terminal 2, located outside the first terminal 1, needs to provide a large and stable clamping force to the first terminal 1 to ensure good contact between the accessory and the first terminal 1.

[0044] By setting the rigidity of the second terminal 2 to be greater than that of the first terminal 1, the first terminal 1 is made to easily undergo elastic deformation, facilitating the insertion of accessories into the first terminal 1 through the first insertion interface 111, which helps improve the connection efficiency of the electrical connector 10. In addition, the second terminal 2 can provide a larger clamping force on the first terminal 1, thereby improving the current carrying capacity of the electrical connector 10 while facilitating electrical connection.

[0045] Optionally, the material of the second terminal 2 may include steel.

[0046] For example, the material of the second terminal 2 is stainless steel.

[0047] By making the material of the second terminal 2 include steel, the rigidity of the second terminal 2 can be effectively guaranteed, and the current carrying capacity of the electrical connector 10 can be further improved.

[0048] Optionally, the first terminal 1 is a silver-plated terminal.

[0049] For example, the first terminal 1 is a silver-plated copper terminal, or the first terminal 1 is a silver-plated aluminum terminal.

[0050] By setting the first terminal 1 as a silver-plated terminal, not only can the resistance of the first terminal 1 be reduced, but the first terminal 1 can also have better corrosion resistance and oxidation resistance, thereby further improving the current carrying capacity and reliability of the electrical connector 10.

[0051] Optionally, conductive component 3 is a silver-plated conductive component.

[0052] For example, conductive component 3 is silver-plated copper, or the first terminal 1 is silver-plated aluminum.

[0053] By making the conductive element 3 a silver-plated conductive element, not only can the resistance of the conductive element 3 be reduced, but the conductive element 3 can also have better corrosion resistance and oxidation resistance, thereby further improving the current carrying capacity and reliability of the electrical connector 10.

[0054] In some embodiments, such as Figure 4 and Figure 5 As shown, the first terminal 1 includes a plurality of first spring contacts 11, which together form a first insertion interface 111. The second terminal 2 includes a plurality of first clamping plates 21, which correspond one-to-one with the first spring contacts 11. Each first clamping plate 21 is used to provide clamping force to the corresponding first spring contact 11.

[0055] By configuring the first terminal 1 to include multiple first spring contacts 11, with the multiple first spring contacts 11 forming a first insertion interface 111, the elasticity of the first terminal 1 can be improved, facilitating the insertion of accessories into the first terminal 1 through the first insertion interface 111, which is beneficial to improving the connection efficiency of the electrical connector 10. Furthermore, by configuring the second terminal 2 to include multiple first clamping plates 21, each first clamping plate 21 providing clamping force to the corresponding first spring contact 11, the material amount of the second terminal 2 can be reduced, lowering the cost of the electrical connector 10.

[0056] Optionally, such as Figure 4 and Figure 5 As shown, multiple first spring pieces 11 form two first spring piece groups, which are arranged at intervals along a first direction. Multiple first spring pieces 11 within the same first spring piece group are arranged at intervals along a second direction, where the second direction is perpendicular to the first direction. Correspondingly, multiple first pressing plates 21 form two first pressing plate groups, which are arranged at intervals along the first direction. Multiple first pressing plates 21 within the first pressing plate groups are arranged at intervals along the second direction.

[0057] To make the technical solution of this disclosure easier to understand, the following description uses an example where the orientation of the first connector 111 is upward, the first direction is consistent with the left-right direction, and the second direction is consistent with the front-back direction. The vertical, left-right, and front-back directions are as follows: Figures 1 to 6 As shown.

[0058] For example, such as Figure 4 and Figure 5 As shown, two first spring clip groups are arranged at intervals along the left-right direction, and multiple first spring clips 11 in the same first spring clip group are arranged at intervals along the front-back direction. Two first clamping plate groups are arranged at intervals along the left-right direction, and multiple first clamping plates 21 in the same first clamping plate group are arranged at intervals along the front-back direction. The upper ends of the first spring clips 11 form an upward-facing first insertion interface 111.

[0059] The above-described structure of the first terminal 1 and the second terminal 2 facilitates the processing and manufacturing of the first terminal 1 and the second terminal 2, and helps to reduce the cost of the electrical connector 10.

[0060] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, the other end of the first terminal 1 forms a second plug-in interface 121, and the conductive element 3 is plugged into the second plug-in interface 121.

[0061] For example, the conductive element 3 is disposed on the lower side of the first terminal 1, the lower end of the first terminal 1 forms a second insertion interface 121 with the opening facing downward, and the upper end of the conductive element 3 is inserted into the second insertion interface 121.

[0062] By connecting the conductive element 3 to the second connector 121, it is convenient to connect the conductive element 3 to the first terminal 1, thereby improving the assembly efficiency of the electrical connector 10 and reducing the assembly cost of the electrical connector 10.

[0063] In other embodiments, the other end of the first terminal 1 may also be welded to the conductive element 3.

[0064] Optionally, such as Figure 4 and Figure 5 As shown, the first terminal 1 includes a plurality of second spring contacts 12, which together form a second insertion interface 121. The second terminal 2 includes a plurality of second clamping plates 22, which correspond one-to-one with the second spring contacts 12. Each second clamping plate 22 is used to provide clamping force to the corresponding second spring contact 12.

[0065] By configuring the first terminal 1 to include multiple second spring contacts 12, with the multiple second spring contacts 12 forming a second insertion interface 121, the elasticity of the first terminal 1 can be improved, facilitating the insertion of the conductive component 3 into the first terminal 1 through the second insertion interface 121, which is beneficial to improving the connection efficiency of the electrical connector 10. Furthermore, by configuring the second terminal 2 to include multiple second clamping plates 22, each second clamping plate 22 providing clamping force to the corresponding second spring contact 12, the material amount of the second terminal 2 can be reduced, lowering the cost of the electrical connector 10.

[0066] Optionally, such as Figure 4 and Figure 5 As shown, multiple second spring pieces 12 form two second spring piece groups, which are arranged at intervals along a first direction, and multiple second spring pieces 12 in the same second spring piece group are arranged at intervals along a second direction. Correspondingly, multiple second pressing pieces 22 form two second pressing piece groups, which are arranged at intervals along the first direction, and multiple second pressing pieces 22 in the second pressing piece groups are arranged at intervals along the second direction.

[0067] For example, such as Figure 4 and Figure 5 As shown, two second spring clip groups are arranged at intervals along the left-right direction, and multiple second spring clips 12 in the same second spring clip group are arranged at intervals along the front-back direction. Two second clamping plate groups are arranged at intervals along the left-right direction, and multiple second clamping plates 22 in the same second clamping plate group are arranged at intervals along the front-back direction. The lower ends of the second spring clips 12 form an upward-opening second insertion interface 121.

[0068] The above-described structure of the first terminal 1 and the second terminal 2 facilitates the processing and manufacturing of the first terminal 1 and the second terminal 2, and helps to reduce the cost of the electrical connector 10.

[0069] Optionally, such as Figure 4As shown, the first terminal 1 also includes a first connecting piece 13 and a first welding part 14. The two ends of the first connecting piece 13 are welded through the first welding part 14, so that the first connecting piece 13 is formed into a ring. The first spring piece 11 and the second spring piece 12 are disposed on opposite sides of the first connecting piece 13. Multiple first spring pieces 11 are connected to the first connecting piece 13, and multiple second spring pieces 12 are connected to the first connecting piece 13.

[0070] For example, the first spring piece 11 is disposed on the upper side of the first connecting piece 13, and the second spring piece 12 is disposed on the lower side of the first connecting piece 13. The first spring piece 11, the second spring piece 12, the first connecting piece 13 and the first welding part 14 are integrally stamped.

[0071] When processing the first terminal 1, a first stamping part including a first spring sheet 11, a second spring sheet 12, a first connecting piece 13, and a first welding part 14 can be stamped first, and then the first stamping part can be bent into shape. Figure 4 The shape shown is then welded at both ends through the first welding part 14, so that the first stamping part forms a ring.

[0072] Optionally, such as Figure 5 As shown, the second terminal 2 also includes a second connecting piece 23 and a second welding part 24. The two ends of the second connecting piece 23 are welded through the second welding part 24, so that the second connecting piece 23 is formed into a ring. The first clamping piece 21 and the second clamping piece 22 are disposed on opposite sides of the second connecting piece 23. Multiple first clamping pieces 21 are connected to the second connecting piece 23, and multiple second clamping pieces 22 are connected to the second connecting piece 23.

[0073] For example, the first clamping plate 21 is disposed on the upper side of the second connecting plate 23, and the second clamping plate 22 is disposed on the lower side of the second connecting plate 23. The first clamping plate 21, the second clamping plate 22, the second connecting plate 23, and the second welding part 24 are integrally stamped.

[0074] When processing the second terminal 2, a second stamping part including a first clamping plate 21, a second clamping plate 22, a second connecting plate 23, and a second welding part 24 can be stamped first, and then the second stamping part can be bent into shape. Figure 5 The shape shown is then welded at both ends through the second welding part 24, so that the second stamping part forms a ring.

[0075] In some embodiments, such as Figures 1 to 3 , Figure 6 As shown, conductive component 3 is a conductive sheet.

[0076] By setting the conductive element 3 as a conductive sheet, the current-carrying area of ​​the conductive element 3 can be increased, thereby further improving the current-carrying capacity of the electrical connector 10.

[0077] Optionally, the length of the conductive sheet is 34mm to 42mm.

[0078] For example, the length of the conductive sheet is 38mm.

[0079] By setting the length of the conductive sheet to 34mm to 42mm, the length of the conductive part 3 can be shortened and the cost of the electrical connector 10 can be reduced while facilitating the connection of the conductive part 3 with the first terminal 1 and the electrical connector.

[0080] Optionally, the width of the conductive sheet is 18mm to 22mm.

[0081] For example, the width of the conductive sheet is 20mm.

[0082] By setting the width of the conductive sheet to 18mm to 22mm, the current carrying capacity of the conductive element 3 can be guaranteed while reducing the width of the conductive element 3 and lowering the cost of the electrical connector 10.

[0083] Optionally, the thickness of the conductive sheet is 10mm to 14mm.

[0084] For example, the thickness of the conductive sheet is 12mm.

[0085] By setting the thickness of the conductive sheet to 10mm to 14mm, the thickness of the conductive part 3 can be reduced while ensuring the current carrying capacity of the conductive part 3, thereby reducing the cost of the electrical connector 10.

[0086] Optionally, such as Figures 1 to 3 As shown, the electrical connector 10 also includes a connector housing 4, with a first terminal 1, a second terminal 2, and a portion of the conductive element 3 disposed within the connector housing 4. The connector housing 4 has a first opening 411 and a second opening 421. The first opening 411 corresponds to the first insertion interface 111, and the second opening 421 allows another portion of the conductive element 3 to extend out. The connector housing 4 can be an insulating housing.

[0087] For example, when the accessory is connected to the electrical connector 10, the accessory passes sequentially through the first opening 411 and the first insertion interface 111 and is inserted into the first terminal 1. The portion of the conductive element 3 extending from the second opening 421 is used for connection with the electrical connector.

[0088] By setting the connector housing 4, not only can the first terminal 1, the second terminal 2 and the conductive element 3 be protected, improving the reliability of the electrical connector 10, but the external insulation of the first terminal 1, the second terminal 2 and the conductive element 3 can also be achieved, improving the safety of the electrical connector 10 in use.

[0089] Optionally, such as Figure 3 As shown, the conductive component 3 is provided with a first limiting part 31, and the connector housing 4 is provided with a second limiting part 422. The first limiting part 31 and the second limiting part 422 are mutually limiting.

[0090] By limiting the first limiting part 31 and the second limiting part 422, the limiting between the conductive element 3 and the connector housing 4 can be achieved, thereby improving the connection reliability between the conductive element 3 and the first terminal 1 and further improving the reliability of the electrical connector 10.

[0091] Optionally, one of the first limiting part 31 and the second limiting part 422 is a limiting hole, and the other of the first limiting part 31 and the second limiting part 422 is a limiting protrusion, with the limiting protrusion disposed inside the limiting hole.

[0092] For example, the first limiting part 31 is a limiting hole, and the second limiting part 422 is a limiting protrusion. The limiting protrusion is inserted into the limiting hole to achieve the limiting between the conductive part 3 and the connector housing 4.

[0093] By setting the first limiting part 31 and the second limiting part 422 to the above structure, the structure of the conductive element 3 and the connector housing 4 is simple and easy to manufacture, which helps to further reduce the cost of the electrical connector 10.

[0094] Optionally, such as Figure 3 As shown, the limiting protrusion has a barbed structure.

[0095] For example, such as Figure 3 As shown, the conductive element 3 is disposed on the lower side of the first terminal 1. The limiting protrusion is an upward-facing barbed structure. After the limiting protrusion is inserted into the limiting hole of the conductive element 3, the barbed structure can limit the conductive element 3 to move downward, thus preventing the conductive element 3 from separating from the first terminal 1.

[0096] By setting the limiting protrusion as a barbed structure, the limiting reliability between the conductive part 3 and the connector housing 4 can be improved, thereby further improving the reliability of the electrical connector 10.

[0097] Optionally, such as Figures 1 to 3 As shown, the connector housing 4 includes a first housing 41 and a second housing 42, with the first housing 41 detachably connected to the second housing 42. A first terminal 1 and a second terminal 2 are both disposed within the first housing 41, and a first opening 411 is located within the first housing 41. A portion of the conductive element 3 is disposed within the second housing 42, and a second opening 421 is located within the second housing 42.

[0098] For example, the first housing 41 and the second housing 42 are connected by a snap-fit. When assembling the electrical connector 10, firstly, the first terminal 1 is inserted into the interior of the second terminal 2. Then, the first housing 41 is fitted over the outside of the first terminal 1 and the second terminal 2 from top to bottom. Next, the second housing 42 is fitted over the outside of the first terminal 1 and the second terminal 2 from bottom to top. Then, the second housing 42 is connected to the first housing 41. Finally, the conductive element 3 is inserted into the first terminal 1 from the bottom of the second housing 42.

[0099] By making the first housing 41 and the second housing 42 detachably connected, it is convenient to assemble and disassemble the electrical connector 10, which helps to reduce the cost of the electrical connector 10 and facilitates the maintenance of the electrical connector 10.

[0100] The electrical connector 10 of this embodiment improves the assembly efficiency of the electrical connector 10 and the pair of accessories and reduces the connection cost of the electrical connector 10 and the pair of accessories by inserting the pair of accessories into the first terminal 1. Specifically, the pressure between the first terminal 1 and the pair of accessories can reach 50N, the contact resistance between the first terminal 1 and the pair of accessories can be reduced to 20uΩ, and the current carrying capacity of the electrical connector 10 can reach 450A.

[0101] The motor controller of this disclosure includes the electrical connector 10 described in any of the above embodiments.

[0102] Because the electrical connector 10 of this embodiment has good current carrying capacity, the motor controller of this embodiment also has good current carrying capacity.

[0103] Optionally, such as Figure 6 As shown, the motor controller includes a controller housing 5, and an electrical connector 10 is connected to the controller housing 5. A first insertion interface 111 is located outside the controller housing 5, and a conductive component 3 is located inside the controller housing 5. An electrical connector 6 is provided inside the controller housing 5, and the electrical connector 6 is welded to the conductive component 3.

[0104] For example, the controller housing 5 includes a controller cover and a controller bottom shell. The controller cover and controller bottom shell are connected and form a cavity for accommodating electrical components. An electrical connector 10 is fixed to the controller cover. A first insertion interface 111 is located on the upper side of the controller cover, and a conductive element 3 is located on the lower side of the controller cover and within the cavity. An electrical connector 6 is located within the cavity, and the electrical connector 6 and the conductive element 3 are laser-welded together.

[0105] By welding the electrical connector 6 to the conductive component 3, the resistance at the connection between the electrical connector 6 and the conductive component 3 can be reduced, thereby increasing the current carrying capacity at the connection between the electrical connector 6 and the conductive component 3.

[0106] The vehicle in this disclosure includes the electrical connector 10 described in any of the above embodiments or the motor controller described in any of the above embodiments.

[0107] For example, the vehicle includes a motor controller and a battery pack. The battery pack and the motor controller are electrically connected via an electrical connector 10, that is, the battery pack is electrically connected to a matching accessory, and the matching accessory is plugged into a first plug-in interface 111, thereby realizing the electrical connection between the battery pack and the motor controller, and thus using the battery pack to supply power to the motor controller.
