[0078] Refer to the appendix Figures 1 - 18 An exemplary description is given of a wiring device according to an embodiment of the present application, which wiring device includes a first conductive connection member 100, a second conductive connection member 200, a third conductive connection member 300, a first connection unit 400, a second connection unit 500, and a first insulating bracket 600.

[0079] The first end of the first conductive connector 100 is used to connect to the first energizing device. The first end of the second conductive connector 200 is electrically connected to the second end of the first conductive connector 100. The second end of the second conductive connector 200 is electrically connected to the first end of the third conductive connector 300. The second end of the third conductive connector 300 is used to connect to the second energizing device. Thus, the first energizing device can form an electrical connection with the second energizing device through the first conductive connector 100, the second conductive connector 200, and the third conductive connector 300. In this embodiment, the first energizing device is a controller, and the second control device is a motor. Thus, the controller can form an electrical connection with the motor through the wiring device, and then control the motor to work. In the embodiment of the present application, the motor includes a motor and a generator. There are six first conductive connectors 100, second conductive connectors 200, and third conductive connectors 300. Three of them are used to connect the controller to the motor, and the other three are used to connect the controller and the generator. In some other embodiments, the number of the first conductive connector 100, the second conductive connector 200, and the third conductive connector 300 can be 2, 3, or more. Those skilled in the art can configure according to the situation of the motor to be connected. The first energizing device and the second energizing device can also be other devices that need to be electrically connected except for the controller and the motor.

[0080] The first connection unit 400 is used to connect the second end of the first conductive connector 100 and the first end of the second conductive connector 200 to make them contact to form an electrical connection. The second connection unit 500 is used to connect the second end of the second conductive connector 200 and the first end of the third conductive connector 300 to make them contact to form an electrical connection. Thus, the second end of the second conductive connector 500 can be connected to the second energizing device through the third conductive connector 300. It should be noted that the first connection unit 400 is floatingly arranged on the first insulating bracket 600. Here, the so-called floating means that it can move within a small range on the first insulating bracket 600. Thus, when there are errors between the first conductive connector 100 and the second conductive connector 200 due to manufacturing, assembly, etc., or when the wiring device vibrates as a whole, the gap caused by manufacturing, assembly errors or vibration between the first conductive connector 100 and the second conductive connector 200 can be compensated by the floating of the first connection unit 400. When the first conductive connector 100 and the second conductive connector 200 pass through a large current, it is not easy to appear ablation phenomenon, reducing the safety risk and ensuring the stable connection between the first energizing device and the second energizing device. In this embodiment, the second connection unit 500 is fixedly connected to the first insulating bracket 600. That is, the second connection unit 500 can fix the second end of the second conductive connector 200 and the first end of the third conductive connector 300 on the first insulating bracket 600.

[0081] It should be noted that in the embodiments of the present application, the first end and the second end of the first conductive connector 100 refer to two different positions of the first conductive connector 100, and it is not limited that the first conductive connector 100 has only two ends. The first end and the second end are not limited to being the two ends of the first conductive connector 100 in a certain direction (such as its length direction, width direction, etc.). When the first conductive connector 100 is in a strip structure, the first end and the second end of the first conductive connector 100 are preferably the two ends of the first conductive connector 100 in its length direction or extension direction. Similarly, the first end and the second end of the second conductive connector 200 refer to two different positions of the second conductive connector 100, and it is not limited that the second conductive connector 200 has only two ends. The first end and the second end are not limited to being the two ends of the second conductive connector 200 in a certain direction (such as its length direction, width direction, etc.). When the second conductive connector 200 is in a strip structure, the first end and the second end of the second conductive connector 200 are preferably the two ends of the second conductive connector 100 in its length direction or extension direction.

[0082] See the appendix Figures 1 - 7, in the embodiment of the present application, the wiring device further includes a second insulating bracket 700, which is injection molded from an insulating material and is used to fix, support, and isolate the first conductive connectors 100, so that the first conductive connectors 100 are insulated from each other. The first conductive connectors 100 are rigid copper bars or other suitable conductive connectors, and are integrally injection molded with the second insulating bracket 700, that is, the first conductive connectors 100 are incorporated into the second insulating bracket 700 during the injection molding of the second insulating bracket 700, so that the second insulating bracket 700 and the first conductive connectors 100 are integrally combined by injection molding; specifically, during the integral injection molding, the first conductive connectors 100 are used as part of the mold, so that the second insulating bracket 700 is integrally formed with the first conductive connectors 100 when it is molded. A through hole 111 is provided at the first end of the first conductive connector 100, and a bolt blind hole 710 corresponding to the through hole 111 is provided on the second insulating bracket 700. The through hole 111 is located outside the bolt blind hole 710 and is coaxial with the bolt blind hole 710. Thus, a bolt can be used to pass through the connection terminal on the first energizing device and the through hole 111 to engage with the bolt blind hole 710, so as to clamp and fix the connection terminal on the first energizing device and the first end of the first conductive connector 100 between the bolt and the second insulating bracket 700, and make the connection terminal on the first energizing device and the first end of the first conductive connector 100 contact to form an electrical connection. In the embodiment of the present application, a groove is provided at the position of the bolt blind hole 710 on the second insulating bracket 700, and the groove can be matched with the shape of the connection terminal on the first energizing device. The through hole 111 and the bolt blind hole 710 are located at the bottom of the groove, and the provision of the groove facilitates the alignment and connection of the connection terminal on the first energizing device with the through hole 111 and the bolt blind hole 710. In the embodiment of the present application, a plurality of grooves 720 are further provided on the second insulating bracket 700. The grooves 720 are weight-reducing grooves and heat-dissipating grooves, which are used to achieve the lightweight of the second insulating bracket 700 and meet the heat-dissipating requirements of the first conductive connectors 100 on the premise of meeting the strength requirements. In the embodiment of the present application, a plurality of mounting bolt holes 730 are further provided on the second insulating bracket 700. The mounting bolt holes 730 are used to enable the second insulating bracket 700 to be fixedly installed on the equipment to which the wiring device is applied through bolts, for example, installed on the frame of a vehicle. In some other embodiments, the second insulating bracket 700 may not be provided, but a mounting and fixing structure may be provided on the equipment where the wiring device is installed to fix, support, and isolate the plurality of first conductive connectors 100.

[0083] See appendix Figures 7 - 9, in the embodiment of the present application, the first conductive connector 100 includes a first connection segment 110, a second connection segment 120, and a plurality of bending segments. The first connection segment 110 is connected to the second connection segment 120 through the plurality of bending segments. A through hole 111 is provided on the first connection segment 110, and the first connection segment 110 is used to connect to the first energizing device. The second connection segment 120 is conductively connected to the first end of the second conductive connector 200 and is perpendicular to the first connection segment 110. A bolt hole 112 is provided on the second connection segment 120. The plurality of bending segments include a bending segment 130 and a bending segment 140. The bending segment 130 is connected to the second connection segment 120, the bending segment 130 is perpendicular to the second connection segment 120 and parallel to the first connection segment 110. There is at least one bending segment 140 and it is connected between the bending segment 130 and the first connection segment 110. The angle between each bending segment 140 and the bending segment 130 is greater than or equal to 0° and less than or equal to 90°. By such a setting, the wiring of the plurality of first conductive connectors 100 can be made more compact, saving space occupation, meeting the requirements of space layout and installation, and being able to improve the deformation margin. Figure 7 The first conductive connector 100 shown in only has one bending segment 140, and the number of bending segments 140 in other first conductive connectors 100 is two or three. In the embodiment of the present application, the first connection segment 110, the bending segment 130, and the bending segment 140 are all located in the second insulating bracket 700, and the second connection segment 120 extends out of the second insulating bracket 700. Refer to the appendix Figure 9 , the length of the second connection segment 120 located outside the insulating bracket, that is, the distance D1 between the side of the second connection segment 120 facing the first connection segment 110 and the side of the second connection segment 120 away from the first connection segment 110, is greater than or equal to 27 mm, that is, the second connection segment 120 is at least 27 mm; the distance D3 between the side of the second connection segment 120 away from the first connection segment 110 and the side of the first connection segment 110 away from the second connection segment 120 is greater than or equal to 60 mm; the effective connection length (that is, the effective contact length) between the second connection segment 120 and the second conductive connector 200 is 15 mm. The deformation margin of the second connection segment 120 in the first conductive connector 100 of the present application is very small during vibration. If it is fixedly connected to other conductive connectors in a conventional manner (for example, directly fixed on the terminal block by bolts), it is very easy to generate a gap with other conductive connectors during vibration, and it is very easy to cause ablation when passing a large current. And in the present application, by configuring it to be floatingly connected to the second conductive connector 200, the gap generated between the first conductive connector 100 and the second conductive connector 200 due to vibration can be compensated in a floating manner, so that it is not easy to cause ablation when passing a large current.

[0084] Refer to the appendix Figures 10 - 17, in the embodiment of the present application, a via hole 121 is provided at the second end of the first conductive connector 100, and a via hole 210 is provided at the first end of the second conductive connector 200. The via hole 121 and the via hole 121 can be circular holes or waist-shaped holes. Configuring them as waist-shaped holes can better compensate for assembly errors. The second conductive connector 200 is a rigid copper bar or other suitable conductive connectors. The first connection unit 400 can include a first clamping member and a second clamping member. The first clamping member partially passes through the via hole 121 and the via hole 210 and is fixedly connected to the second clamping member to clamp and fix the second end of the first conductive connector 100 and the first end of the second conductive connector 200 between the first clamping member and the second clamping member. The second end of the first conductive connector 100 and the first end of the second conductive connector 200 are in contact to form an electrical connection. In this embodiment, the first clamping member is the first bolt 410, and the second clamping member is the first nut 420. The first nut 420 can be a square nut, a hexagonal nut, or other nuts commonly used in the art. A first installation groove 620 matching the first nut 420 is provided on the first insulating bracket 600. The size of the first installation groove 620 is slightly larger than that of the first nut 420, and the first nut 420 is floatingly accommodated in the first installation groove 620. The first installation groove 620 can limit the rotation of the first nut 420 therein, thereby facilitating the engagement of the first bolt 410 and the first nut 420 to form a fixed connection. A through hole 621 is provided at the bottom of the first installation groove 620. The diameter of the through hole 621 is larger than the diameter of the first bolt 410 passing through it. Thus, the through hole 621 does not limit the movement of the first bolt 410 in the axial direction of the through hole. In some other embodiments, the first bolt 410 (such as the head of the first bolt 410) can also be configured to be floatingly accommodated in the first installation groove 620. That is, the first clamping member or the second clamping member can be configured to be floatingly accommodated in the matching first installation groove 610. When an error occurs between the first conductive connector 100 and the second conductive connection due to reasons such as assembly and manufacturing, or when vibration occurs, the first clamping member and the second clamping member can float (such as up and down) in the first installation groove 620. Thus, the gap generated between the first conductive connector 100 and the second conductive connector 200 due to errors or vibrations can be effectively compensated, so that it is not easily ablated when passing a large current. The first clamping member and the second clamping member can also be other suitable clamping and fixing members other than bolts and nuts.

[0085] See attached Figures 10 - 18, in the embodiment of the present application, a via hole 220 is provided at the second end of the second conductive connector 200, and a via hole 310 is provided at the first end of the third conductive connector 300. The second connection unit 500 includes a third clamping member and a fourth clamping member. The third clamping member partially passes through the via hole 220 and the via hole 310 and is fixedly connected to the fourth clamping member to clamp and fix the second end of the second conductive connector 200 and the first end of the third conductive connector 300 between the third clamping member and the fourth clamping member. The second end of the second conductive connector 200 and the first end of the third conductive connector 300 are in contact to form an electrical connection. In this embodiment, the third clamping member is a second bolt 510, and the fourth clamping member is a second nut 520. The second nut 520 can be a square nut, a hexagonal nut or other commonly used nuts in the art. A second mounting groove 630 matching the second nut 520 is provided on the first insulating bracket 600, and the second nut 520 is received in the second mounting groove 630. The second mounting groove 630 can limit the rotation of the second nut 520 therein, thereby facilitating the engagement of the second bolt 510 and the second nut 520 to form a fixed connection. A threaded hole 631 is provided at the bottom of the second mounting groove 630, and the second bolt 510 engages with the threaded hole 631. Thus, the second end of the second conductive connector 200 and the first end of the third conductive connector 300 are detachably fixed to the second insulating bracket 700, that is, the second nut 520 is fixedly received in the second mounting groove 630. The threaded hole 631 can also be replaced with a threaded connection portion such as a threaded groove, and the second bolt 510 can engage with it to be detachably fixed to the first insulating bracket 600. Thus, the second end of the second conductive connector 200 is fixed, and the first end of the second conductive connector 200 is floating. The third clamping member and the fourth clamping member can also be other suitable clamping and fixing members other than bolts and nuts.

[0086] In some other embodiments, the second connection unit 500 may include a fifth clamping member. The fifth clamping member partially passes through the through hole 220 and the through hole 310 and is fixedly connected to the first insulating bracket 600, so as to clamp and fix the second end of the second conductive connector 200 and the first end of the third conductive connector 300 between the fifth clamping member and the first insulating bracket 600. The second end of the second conductive connector 200 and the first end of the third conductive connector 300 are in contact to form an electrical connection. The fifth clamping member may be a bolt, and a threaded connection portion (such as a threaded groove or a threaded hole) matching with it is provided on the first insulating bracket 600. The threaded connection portion may be integrally formed with the first insulating bracket 600 or be the thread of a nut embedded in the first insulating bracket 600. The bolt passes through the through hole 220 and the through hole 310 and meshes with the threaded connection portion to achieve a fixed connection. In some embodiments, the fifth clamping member may be a rivet, and a through hole matching with it is provided on the first insulating bracket 600. The rivet passes through the through hole 220, the through hole 310 and the through hole on the first insulating bracket 600 and is riveted and fixed to the first insulating bracket 600.

[0087] See the appendix Figures 10 - 16, in the embodiment of the present application, a floating groove 610 is provided on the insulating bracket. The extending direction of the floating groove 610 is the same as that of the second conductive connector 200. The first nut 420 and the second mounting groove 630 are located at the bottom of the floating groove 610. The second conductive connector 200 is located in the floating groove 610 and the depth of the floating groove 610 is greater than the thickness of the second conductive connector 200. The first end of the second conductive connector 200 can float within the floating groove 610. A limiting portion 640 is further provided on the insulating bracket. The limiting portion 640 is located at the top of the floating groove 610 and is used to limit the second conductive connector 200 from leaving the floating groove 610, that is, to limit the floating range of the second conductive connector 200 and prevent its floating range from being too large. In the embodiment of the present application, a positioning protrusion 650 is further provided in the floating groove 610, and a positioning hole 230 matching the positioning protrusion 650 is provided on the second conductive connector 200. When the second conductive connector 200 is located in the floating groove 610 and the positioning protrusion 650 is inserted into the positioning hole 230, the through holes 210 and 220 at both ends of the second conductive connector 200 are respectively aligned with the through holes of the first nut 420 in the first mounting groove 620 and the second nut 520 in the second mounting groove 630, so as to facilitate the connection of the first bolt 410 and the second bolt 510. In the embodiment of the present application, a plurality of grooves 660 are further provided on the side of the first insulating bracket 600 away from the second conductive connector 200. The grooves 660 are weight-reducing grooves and heat-dissipating grooves, which are used to achieve the light weight of the first insulating bracket 600 and meet the heat-dissipating requirements of the second conductive connector 200 on the premise of meeting the strength requirements. In the embodiment of the present application, mounting bolt holes 670 and positioning pins 680 are further provided on the first insulating bracket 600. The mounting bolt holes 670 are used to enable the first insulating bracket 600 to be fixedly installed on the equipment to which the wiring device is applied through bolts, and the positioning pins 680 are used for positioning when the first insulating bracket 600 is installed. For example, when the wiring device is the drive assembly of a vehicle, the first insulating bracket 600 can be selectively fixedly installed on the motor, motor controller or transmission of the drive assembly through bolts.

[0088] See appendix Figure 18 , in the embodiment of the present application, a fixing hole 320 is provided at the second end of the third conductive connector 300, which is formed by a press riveting process and is used to fix the connection terminal or connection wire of the second energizing device therein. The third conductive connector 300 can be bent at 90° or other appropriate angles, and those skilled in the art can configure it according to the connection requirements.

[0089] It should be noted that in the embodiments of the present application, the first end and the second end of the third conductive connector 300 refer to two different positions of the third conductive connector 300, and it is not limited that the third conductive connector 300 has only two ends. The first end and the second end are not limited to be the two ends of the third conductive connector 300 in a certain direction (such as its length direction, width direction, etc.). When the third conductive connector 300 is in a strip structure, the first end and the second end of the third conductive connector 300 are preferably the two ends of the third conductive connector 300 in its length direction or extension direction.

[0090] In some other embodiments, when the connection terminal or the connection wire of the second energizing device is short and the deformation margin is insufficient, the second connection unit 500 can be configured to be floatingly disposed on the first insulating bracket 600. That is, the threaded hole 631 provided at the bottom of the second mounting groove 630 can be replaced with a through hole with a diameter larger than that of the second bolt 510 passing through it, so that it does not limit the movement of the second bolt 510, and the second bolt 510 and the second nut 520 can float in the second mounting groove 630. The floating of the first connection unit 400, the second connection unit 500 and the second conductive connector 200 as a whole is restricted by the limiting portion 640 on the floating groove 610, so that when floating, neither the first nut 420 nor the second nut 520 can leave the corresponding mounting groove. In some other embodiments, the second bolt 510 (such as the head of the second bolt 510) can also be configured to be floatingly received in the second mounting groove 630. In some other embodiments, through holes or threaded holes may not be provided at the bottoms of the first mounting groove 620 and the second mounting groove 630, but the lengths of the first bolt 410 and the second bolt 510 can be configured such that after meshing with the first nut 420 and the second nut 520, they do not protrude from the other end.

[0091] In some other embodiments, the wiring device may not have the third conductive connector 300. Instead, a fixing hole similar to the fixing hole 320 may be provided at the second end of the second conductive connector 200. This fixing hole is used to fix the connection terminal or connection wire of the second energizing device, and the via hole 220 is located between the via hole 210 and this fixing hole. The second end of the second conductive connector 200 may be connected to the first insulating bracket 600 through a second bolt 510 and a threaded connection portion (such as a threaded groove or a threaded hole) provided on the first insulating bracket 600 that matches it. This threaded connection portion may be integrally formed with the first insulating bracket 600 or be the thread of a nut embedded in the first insulating bracket 600. The second bolt 510 passes through the via hole 220 and meshes with this threaded connection portion to clamp and fix the second end of the second conductive connector 200 between the second bolt 510 and the first insulating bracket 600. The present application also provides a drive assembly, which includes a controller, a motor, and the wiring device as described above. Among them, when the wiring device includes the third conductive connector 300, the first end of the first conductive connector 100 is connected to the controller, and the second end of the second conductive connector 200 is connected to the motor through the third conductive connector 300. The controller is conductively connected to the motor (motor and generator) through the first conductive connector 100, the second conductive connector 200, and the third conductive connector 300, so that the motor can be controlled to work. In some embodiments, when the wiring device does not include the third conductive connector 300, the first end of the first conductive connector 100 is connected to the controller, and the second end of the second conductive connector 200 is directly connected to the motor. The controller is conductively connected to the motor through the first conductive connector 100 and the second conductive connector 200. In some embodiments, those skilled in the art can change the number of the first conductive connector 100, the second conductive connector 200, and the third conductive connector 300 as needed, so that the controller is conductively connected to only the motor or only the generator through them.

[0092] The present application also provides a vehicle, which includes the drive assembly as described above. The vehicle may be, for example, a hybrid electric vehicle or other suitable vehicles that require the use of an electric motor. Among them, the first connection unit 400 is disposed on the first insulating bracket 600 in a floating manner along the height direction of the vehicle, that is, the first connection unit 400 can float in the height direction of the vehicle. The height direction of the vehicle is perpendicular to the ground direction (that is, the so-called up and down direction). When the vehicle is running, the vibration of the vehicle is generally along its height direction, that is, the vibration of the wiring device as a whole is along the height direction of the vehicle. By disposing the first connection unit 400 on the first insulating bracket 600 in a floating manner along the height direction of the vehicle, when the vehicle vibrates along its height direction, the first connection unit 400 can also synchronously float along the height direction of the vehicle to compensate for the gap generated between the first conductive connection member 100 and the second conductive connection member 200 due to vibration, so that when the first conductive connection member 100 and the second conductive connection member 200 pass a large current, the phenomenon of ablation is not likely to occur, reducing the safety risk and ensuring the stable connection between the controller and the motor.
