Description

Technical Field

[0001] The invention relates to the technical field of connecting wires, and in particular to a wear-resistant and bending-resistant connecting wire. Background Art

[0002] At present, connecting wires are a commonly used power connection accessory, which is widely used in power distribution cabinets, electrical equipment and power batteries of electric vehicles. Among them, the power batteries of electric vehicles are connected by multiple battery modules, and connecting wires are needed to connect multiple battery modules.

[0003] Chinese invention patent CN103112161A discloses a process for processing thermoplastic tubes with wires. In the process of cutting the thermoplastic tubes with scissors, the length of each section of the thermoplastic tube is such that when it is sheathed on each section of the wire, each end of the thermoplastic tube is 10 mm shorter than the wire. Then, a hot air gun is used to bake, heat, shrink and shape each section of the thermoplastic tube that has been sheathed on each section of the wire.

[0004] However, the above patents have the following defects:

[0005] (1) The existing connecting wire has poor bending resistance, which can easily lead to the spring connecting wire breaking during use, thereby causing damage to the connecting wire and shortening the service life of the connecting wire.

[0006] (2) The connecting wires may easily cause the outer layer of the wiring harness to wear or even break over a long period of time, which may easily lead to dangers such as short circuits, causing unnecessary economic losses. Utility Model Content

[0007] In order to solve one or some technical problems existing in the prior art, the purpose of the present application is to provide a wear-resistant and bending-resistant connecting wire, which can provide bending compensation when the connecting wire is bent to avoid breaking of the connecting wire.

[0008] In order to solve the above existing technical problems, one of the purposes of this application is achieved by adopting the following technical solution:

[0009] A wear-resistant and bending-resistant connecting wire comprises a wire body, a waterproof layer fixedly sleeved on the outer side wall of the wire body, an elastic layer fixedly arranged on the outer side wall of the waterproof layer, a high-temperature resistant layer fixedly arranged on the outer side wall of the elastic layer, and a wear-resistant layer fixedly arranged on the outer side wall of the high-temperature resistant layer.

[0010] Furthermore, the waterproof layer is a waterproof plastic film.

[0011] Furthermore, the elastic material is made of rubber.

[0012] Furthermore, the high temperature resistant layer comprises silicone tape layers arranged inside and outside, and a fireproof ceramic layer is fixedly arranged between the two silicone tape layers.

[0013] Furthermore, the wear-resistant layer is a nylon layer.

[0014] Furthermore, a plurality of rubber protrusions are evenly and fixedly provided on the outer side wall of the wear-resistant layer.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) By setting an elastic layer, the elastic layer can provide bending compensation when the connecting wire is bent, thereby avoiding the breakage of the connecting wire and improving the service life of the connecting wire. Compared with the prior art, the present invention solves the technical problem that the existing connecting wire has poor bending resistance and is prone to breakage during use, thereby causing damage to the connecting wire and affecting the service life of the connecting wire.

[0022] Embodiment 1:

[0023] like Figure 1 As shown, this embodiment provides a wear-resistant and bending-resistant connecting wire, which includes a wire body 1, a waterproof layer 3 fixedly sleeved on the outer wall of the wire body 1, an elastic layer 2 fixedly provided on the outer wall of the waterproof layer 3, a high-temperature resistant layer 6 fixedly provided on the outer wall of the elastic layer 2, and a wear-resistant layer 4 fixedly provided on the outer wall of the high-temperature resistant layer 6.

[0024] The wear-resistant and bending-resistant connecting wire comprises a wire body 1, a waterproof layer 3 is fixedly sleeved on the outer wall of the wire body 1, an elastic layer 2 is fixedly arranged on the outer wall of the waterproof layer 3, a high-temperature resistant layer 6 is fixedly arranged on the outer wall of the elastic layer 2, and a wear-resistant layer 4 is fixedly arranged on the outer wall of the high-temperature resistant layer 6. By arranging the elastic layer 2, the elastic layer 2 can provide bending compensation when the connecting wire is bent, avoid the breakage of the connecting wire, and improve the service life of the connecting wire. Compared with the prior art, the technical problem that the bending resistance of the existing connecting wire is poor, the spring connecting wire is easily broken during use, thereby causing damage to the connecting wire and affecting the service life of the connecting wire is solved.

[0025] Furthermore, the waterproof layer 3 is a waterproof plastic film, and the waterproof layer 3 increases the waterproof performance.

[0026] Furthermore, the elastic layer 2 is made of rubber material and can provide bending compensation when the connecting line bends.

[0027] Furthermore, the high temperature resistant layer 6 includes silicone tape layers 7 arranged inside and outside, and a fireproof ceramic layer 8 is fixedly arranged between the two silicone tape layers 7. The high temperature resistant layer 6 composed of the double-layer silicone tape layer 7 and the fireproof ceramic layer 8 has strong high temperature resistance, can greatly improve the high temperature resistance level, and make the wire material play a role of high temperature resistance.

[0028] Furthermore, the wear-resistant layer 4 is a nylon layer, and a plurality of rubber protrusions 5 are evenly and fixedly arranged on the outer wall of the wear-resistant layer 4. When the connecting wire contacts with an external object, the rubber protrusions 5 contact with the external object, so that the outer side of the connecting wire can be prevented from being worn or damaged. Meanwhile, the setting of the nylon layer can greatly improve the wear resistance of the outer side of the connecting wire. Compared with the prior art, the technical problem that the outer skin of the wiring harness is easily worn or even broken due to long-term wiring is solved, thereby easily causing dangers such as short circuits and causing unnecessary economic losses is solved.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
