[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1 , Figure 2 As shown, Figure 1 What is shown is the overall schematic diagram of the connecting wires in the embodiment, Figure 2 Shown is an exploded schematic diagram of the connection lines in the embodiment.

[0022] The device includes a cable 10 and a rubber coating structure 20. The cable 10 includes a main line segment 11 and a connecting segment 12. The connecting segment 12 is arranged at both ends of the main line segment 11. The connecting segment 12 is a conductive wire bundle that is welded and pressed after the insulation layer is stripped. The rubber coating structure 20 is coated on the outside of the connecting segment 12.

[0023] The conductive wire harness of the cable 10 is preferably a copper wire harness. After the insulation layer of the connecting section 12 is stripped, the copper wire harness is welded and pressed together through an ultrasonic square pressing process to form an integrated structure with a certain shape. Compared with the structure obtained by the process of sleeve-wrapping a square tube and stamping the copper wire harness in the prior art, the bonding strength between the conductive wires of the connecting section is stronger, and the risk of the harness being separated from the copper tube is avoided. In addition, the manufacturing raw material: square tube is reduced, saving a lot of cost.

[0024] The encapsulated structure 20 is coated on the outside of the connecting section 12 to play the role of insulation, connection and protection, and the encapsulated structure 20 at both ends is set in different colors to distinguish the positive and negative electrodes, such as red for the positive electrode and blue for the negative electrode. The encapsulated structure 20 is set on the outside of the connecting section 12 by injection molding.

[0025] like Figure 2 As shown, Figure 2 Shown is an exploded schematic diagram of the connection lines in the embodiment.

[0026] The connecting section 12 is provided with a mounting hole 13, which facilitates the connection between the device and the battery pack or the outlet or the junction box end;

[0027] The connecting section 12 is preferably rectangular in shape, with a simple structure, saving mold development difficulty and low manufacturing difficulty. The connecting section 12 is generally connected to other devices by fasteners, and the mounting hole 13 is convenient for the installation of fasteners, which include screws / flat washers / spring washers, etc.

[0028] The rubber-coated structure 20 includes a sheath 21 and a protective cover 22. The shape of the sheath 21 matches the shape of the connecting section 12. A mounting hole 2 is provided on the sheath 21 at a position corresponding to the mounting hole 13. The protective cover 22 can cover the mounting hole 2 of the sheath 21, and the sheath 21 and the protective cover 22 are connected by a set connecting piece 23.

[0029] The sheath 21 plays a protective role on the connecting section 12. The positions of the mounting hole 2 and the mounting hole 13 correspond to each other, which is convenient for the installation of the fasteners. After the fasteners are installed, the protective cover 22 plays a further protective role, such as dust prevention and leakage prevention. The protective cover 22 is connected to the sheath 21 through the connector 23, which is convenient for carrying the entire device.

[0030] Specifically, the connecting piece 23 is made of a flexible material and does not affect the covering of the protective cover 22 and the sheath 21 .

[0031] The end of the protective cover 22 that covers the sheath 21 is provided with an inner groove 221, which is a hexagonal structure. The inner groove 221 of the hexagonal structure can be closely matched with the outer hexagonal screw head of one of the fasteners, further improving the sealing effect of the protective cover 22, thereby further improving its protection performance.

[0032] Working principle: The utility model welds and presses the copper wire harness to form a connecting section of a certain shape through the ultrasonic squaring process, so that the bonding strength between the conductive wires of the connecting section is stronger, and the wire harness is avoided from being detached, and the cost is saved. The utility model has a rubber-coated structure and an inner groove of the hexagonal structure opened on the end of the protective cover that is covered with the sheath. The inner groove of the hexagonal structure can be tightly matched with the outer hexagonal screw head of one of the fasteners, thereby further improving the sealing effect of the protective cover, thereby further improving its protective performance.
