[0050] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0051] The material of the conductor 210 in the embodiments of the present application is metal, which can be aluminum or aluminum alloy, copper or copper alloy, and the conductor 210 can be a multi-core cable or a solid cable. Embodiment 1

[0052] As Figures 1-6As shown, the electric connection device 1 can include at least one sleeve assembly 100, or can include a plurality of sleeve assemblies 100. Each sleeve assembly 100 includes n layers of conductive devices 10, wherein n is a positive integer, and the nth layer of conductive devices 10 in the n layers of conductive devices 10 is at least partially sleeved outside the (n-1)th layer of conductive devices 10; and at least one external conductive device 200, which is electrically connected with any layer of conductive devices 10 in the n layers of conductive devices 10 to form a loop group 600.

[0053] In an embodiment, as shown, Figure 3 The sleeve assembly 100 is one, n=4, and the conductive devices 10 from top to bottom are the first layer, the second layer, the third layer, and the fourth layer, respectively. The first layer is the innermost layer, and the fourth layer is the outermost layer (hereinafter referred to as the above). Each layer of conductive devices 10 is connected with the external conductive device 200 to form different loop groups 600. The external conductive device 200 can be a terminal or a wire, and the material can be the same as or different from that of the conductive device 10. When the external conductive device 200 is a terminal, one end of the terminal is electrically connected with the conductive device 10, and the other end of the terminal can be connected with a corresponding wire as needed. The length and lead direction of the external conductive device 200 are set according to actual needs.

[0054] The cross-sectional area of the sleeve assembly 100 can be polygonal. Preferably, for convenience of placement, as shown in Figure 8 and Figure 14 The cross-sectional area of the sleeve assembly 100 is quadrilateral or hexagonal.

[0055] As shown in Figure 1 and Figure 2 The external conductive device 200 of the first layer can pass through the second layer of conductive devices 10, the third layer of conductive devices 10, and the fourth layer of conductive devices 10 in sequence. Similarly, different external conductive devices 200 can be electrically connected with any layer of conductive devices 10 to form a loop.

[0056] In this application, different conductive devices 10 in each sleeve assembly 100 can carry different currents. The sleeve assembly 100 with such a structure is more compact and orderly, and facilitates the arrangement of each conductive device 10, reduces the wiring space, and is more convenient for installation and maintenance. In addition, the outer conductive device 10 of the multi-layer sleeve assembly can shield the signals generated by the inner conductive device 10 to some extent, reducing the signal interference to the outside.

[0057] The nth layer of conductive devices 10 in the n layers of conductive devices 10 is at least partially sleeved outside the (n-1)th layer of conductive devices 10. In one embodiment, in the extension direction of the electric connection device 1, part of the nth layer of conductive devices 10 is not covered by the (n+1)th layer. In another embodiment, as shown in Figure 1As shown, the length of each layer of the conductive device 10 is the same, and the conductive device 10 of the nth layer is entirely covered by the conductive device 10 of the (n+1)th layer.

[0058] The external conductive device 200 can be one or multiple, and the external conductive device 200 can be electrically connected with any layer of the conductive device to form a loop group 600. As shown, Figure 9 As shown, an external conductive device 200 is shown, which can be electrically connected with different layers of the conductive device 10. In the process of vehicle wiring, according to the actual use environment, each sleeve assembly 100 can be combined with multiple layers of the conductive device 10, and the number of external conductive devices 200 can also be set according to actual needs.

[0059] When the external conductive device 200 is multiple, multiple external conductive devices 200 can be electrically connected with different layers of the conductive device 10 of the n layers of the conductive device 10 to form multiple loop groups 600. As shown, Figure 3 As shown, the conductive device 10 is 4 layers, and the external conductive device 200 is 12, and every 3 external conductive devices 200 can be electrically connected with the 4 layers of the conductive device 10 to form different loop groups 600. For example, when the conductive device 10 is 3 layers, and the external conductive device 200 is 2, the two external conductive devices 200 can be electrically connected with any two layers of the 3 layers of the conductive device 10.

[0060] In addition, multiple external conductive devices 200 can also be electrically connected with the same layer of the conductive device 10 of the n layers of the conductive device 10 to form a loop group 600. For example, the conductive device 10 is 2 layers, and the external conductive device 200 is 2, and the 2 external conductive devices 200 are all electrically connected with the outermost layer of the conductive device 10 or all electrically connected with the innermost layer of the conductive device.

[0061] In order to ensure various connection modes, according to the actual wiring needs, the number of external conductive devices 200 connected by different layers of the conductive device 10 can be different. In order to ensure that each loop group does not interfere with each other, multiple external conductors 210 are arranged at intervals in the radial projection of the sleeve assembly 100.

[0062] The electrical connection mode of the conductive device 10 and the external conductive device 200 can also generally use crimping or welding, and the welding mode is preferred here, including ultrasonic welding, magnetic induction welding, etc., which can weld the two together.

[0063] As shown in the embodiment of the application, Figure 3 and Figure 4 As shown, the first layer of the conductive device 10 can be solid; another mode is as shown in Figure 1As shown, the first layer of conductive devices 10 is hollow, and the cross-section of the conductive device 10 is quadrilateral, and the cross-section of the conductive device 10 of the nth layer is generally set to be quadrilateral or hexagonal in order to cover the (n-1)th layer of conductive devices 10 on the inner side.

[0064] In the present application, the external conductive device 200 is electrically connected to the conductive device 10 through the opening 30. Specifically, the nth layer of conductive devices 10 is provided with at least one opening 30, and the external conductive device 200 is electrically connected to the conductive device 10 on the inner side through the opening 30. Here, except that the conductive device 10 of the innermost layer (the first layer) does not need to be provided with an opening 30, the conductive device 10 of the remaining layers needs to be provided with an opening 30. The position of the opening 30 is set according to the actual use position, and the external conductive device 200 can be connected to the conductive device 10 covered on the inner side through the openings 30 of each layer.

[0065] Specifically, when n = 2, as shown in Figure 5 and Figure 6 each sleeve assembly 100 includes a first conductive device 11 and a second conductive device 12 (shown in the upper two layers in the figure) extending in the axial direction, the second conductive device 12 is at least partially sleeved on the outer side of the first conductive device 11, and the second conductive device 12 is provided with at least one first opening 31. Here, the first opening 31 can be provided with multiple (the holes on the same layer of conductive device 10 are all first openings 31). The number of first openings 31 is generally greater than or equal to the number of external conductive devices 200, and the at least one external conductive device 200 is electrically connected to the first conductive device 11 through the first opening 31, and / or at least one external conductive device is directly electrically connected to the second conductive device 12.

[0066] Specifically, when n = 3, as shown in Figure 5 and Figure 6 it further includes a third conductive device 13, the third conductive device 13 is at least partially sleeved on the outer side of the second conductive device 12, and the third conductive device 13 is provided with at least one second opening 32, and the external conductive device 200 is electrically connected to the first conductive device 11 through at least one first opening 31 and at least one second opening 32, respectively, and at least one external conductive device 200 is electrically connected to the second conductive device 12 through another second opening 32. The number of openings 30 of the nth layer of conductive devices 10 is greater than or equal to the total number of external conductive devices 200 on all layers of conductive devices 10 on the inner side. n≥2, n is a positive integer, which will not be listed one by one here.

[0067] In another embodiment, as shown in Figure 10As shown, the present application also includes built-in conductive devices 500, which can also be electrically connected with the conductive devices 10 in the adjacent two sleeve joint components 100 through the openings 30. Preferably, the welding connection mode is adopted.

[0068] In an embodiment, in order to save space, facilitate assembly, and facilitate the arrangement along the vehicle body, at least one bending portion 20 is arranged on the sleeve joint component 100.

[0069] As shown in Figure 2 , Figure 4 and Figure 8 , in an embodiment, in order to ensure the insulation between the circuit groups 600, each of the circuit groups 600 has a conductor 210 and an insulator 220 formed on at least the outer surface of the conductor 210.

[0070] An embodiment is that the conductive device 10 and the external conductive device 200 respectively have a conductor 210 and an insulator 220, and when the external conductive device 200 is electrically connected with the conductive device 10, the insulator 220 at the connection position can be removed before the connection.

[0071] In another embodiment, after the conductors 210 of each conductive device 10 and each external conductive device 200 are electrically connected, a glue injection and molding form is adopted between them to insulate the different circuit groups 600. Example 2

[0073] In an embodiment, as shown in Figure 12 , the extension directions of at least two sleeve joint components 100 are different. The adjacent two sleeve joint components 100 can extend in different directions according to actual needs.

[0074] In another embodiment, as shown in Figure 11 , the extension directions of the adjacent two sleeve joint components 100 are the same, and they are arranged side by side. As shown in Figure 7 and Figure 8 , the sleeve joint components 100 are eight, and multiple external conductive devices 200 are respectively electrically connected with different conductive devices 10 of different sleeve joint components 100.
