Description

Technical Field

[0001] The utility model relates to the technical field of automobile electric wires, in particular to an automobile electric wire with ultra-high electronic retention force. Background Art

[0002] Ultra-high holding force automotive wire refers to a wire with very high holding force, used in automobiles.

[0003] In order to reduce manufacturing costs and save wiring space, the OEM proposed a plan to replace the 0.35mm2 wire with 0.22mm2 wire. The automotive performance of the replaced 0.22mm2 wire can remain unchanged, but in the production process of the wire harness, after the 0.22mm2 terminal is crimped, the terminal holding force is only 40N, which does not meet the 50N requirement of 0.35mm2, resulting in an increase in the scrap rate of the wire harness production process, increased costs, and reduced production efficiency; and generally, wires have a certain length. If a fault occurs somewhere in the wire, it may be necessary to destroy the protective cover of the wire to repair the faulty part. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an ultra-high-end electronic retention force automotive wire, which solves the problem in the prior art that if a wire fails somewhere, the protective cover of the wire may need to be destroyed to repair the faulty part.

[0005] To achieve the above-mentioned purpose, the utility model proposes an ultra-high-voltage electrical wire for automobiles, comprising: an insulating layer, a plurality of conductor layers are arranged inside the insulating layer, the conductor layers are formed by twisting a plurality of annealed soft copper wires, a plurality of sheath layers are detachably connected to the outside of the insulating layer, the sheath layers comprise a lower sheath and an upper sheath, the upper sheath is hinged to the upper end of the lower sheath, an embedded component is fixedly connected to the end face of the lower sheath away from the hinge, an embedded groove matching the embedded component is provided on the end face of the upper sheath away from the hinge, and two adjacent sheath layers are detachably connected.

[0006] As a further solution of the utility model: a bulletproof wire is wound on the surface of the annealed soft copper wire, and the bulletproof wire is wound on the surface of the annealed soft copper wire at a certain pitch, and the insulating layer is a polyvinyl chloride material.

[0007] As a further solution of the utility model: a plurality of protrusions are fixedly arranged circumferentially on the outer surface of the insulating layer, and limiting grooves are provided on the mutually close curved surfaces of the lower sheath and the upper sheath, and the limiting grooves are adapted to the protrusions.

[0008] As a further solution of the utility model: a plurality of connecting parts are connected to the outer surface of the sheath layer near one end, a mounting ball is fixedly connected to the end of the connecting part, a plurality of mounting grooves are opened on the outer surface of the sheath layer near the other end, the mounting balls are made of elastic material, the number of the mounting grooves is the same as the number of the mounting balls, and the mounting grooves are adapted to the mounting balls.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The insulation layer of the wire is removably provided with multiple sheath layers, including a lower sheath and an upper sheath, and the lower sheath and the upper sheath are detachably connected. This means that when the wire needs to be repaired, the lower sheath and the upper sheath can be separated to expose the fault for repair.

[0011] 2. The two adjacent sheath layers are detachably connected, which makes it easy to separate the adjacent sheath layers during maintenance and only deal with the fault without destroying the protective sheath of the entire wire.

[0012] 3. By wrapping bulletproof wire on the surface of the annealed soft copper wire of the conductor layer, the terminal holding force after crimping the terminal is increased from 40N to 65N on the basis of ensuring the original conductivity and insulation performance of the wire. Compared with the wire with a specification of 0.35mm2, it not only ensures the terminal holding force, but also reduces the wire cross-section, thereby reducing the manufacturing cost of the automobile.

Compared with the wire with a specification of 0.35mm2, the terminal holding force is guaranteed, the wire cross-section is reduced, and the automobile manufacturing cost is reduced.

[0021] The insulating layer 1 is made of polyvinyl chloride material and has the properties of flame retardancy, liquid resistance, corrosion resistance and scratch resistance.
