Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to an automobile connecting wire with a high-integrated signal. Background Art

[0002] The automotive wiring harness composed of automotive connecting wires is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component that connects the circuit. It is different from ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. Automotive wires are all copper multi-core soft wires, some of which are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), which are soft and not easy to break.

[0003] At present, traditional automobile circuit layout generally uses wire cable cores to connect with terminal connectors directly to gradually form the internal circuit of the car; however, due to the relatively small wiring space of the automobile circuit, when the number of wire cable cores is large, they also need to be sorted and planned, and a large number of terminal connectors are required in the circuit layout process. Since it is impossible to integrate the terminal connectors together, it is inevitable that there will be multiple terminal connectors in a limited space, which makes the staff more difficult to lay out the automobile circuit, and the wires are easily messy, resulting in the staff being unable to quickly find the corresponding wires during later maintenance. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the problem of difficulty in circuit layout caused by narrow wiring space and the use of too many terminal connectors.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highly integrated signal automobile connecting wire, comprising two connecting wires and a terminal connector, wherein a plurality of wire cable cores are arranged inside the two connecting wires, the terminal connector comprises an upper row of connecting terminals and a lower row of connecting terminals, and conductive plastic is arranged on the upper row of connecting terminals and the lower row of connecting terminals; the plurality of wire cable cores extending from the two connecting wires to the outside are respectively connected to the conductive plastic of the upper row of connecting terminals and the lower row of connecting terminals.

[0006] As a further solution of the utility model: the terminal connector is made of plastic material.

[0007] As a further solution of the utility model: the outer layer of the connecting wire is provided with an insulating layer, and the insulating layer is made of extruded TPU material.

[0008] As a further solution of the utility model: the inner layer of the connecting wire is provided with a shielding layer, and the shielding layer is mixed by tinned copper wire and high-strength fiber wire.

[0009] As a further solution of the utility model: cable ties are provided on both sides of the connecting wires, and the cable ties are used to bundle and fix multiple wire cable cores outside the connecting wires.

[0010] As a further solution of the utility model: the front ends of the upper row of wiring terminals and the lower row of wiring terminals are connected to multiple wire cable cores, and the rear ends are electrically connected to multiple differential signal pairs.

[0011] As a further solution of the utility model: a parallel iron sheet is provided on the two connecting wires, the parallel iron sheet is provided with at least two through holes, and the two connecting wires pass through the through holes.

[0012] Compared with the prior art, the beneficial effects of this technical solution are:

[0013] (I) When the wire core is connected to the terminal connector, the multiple wire cores of the two connecting wires are distinguished, and then placed into the conductive plastic on the upper and lower rows of terminals respectively, and crimped to fix the wire core in the conductive plastic. The double-layer side-by-side method is adopted to achieve a high degree of integration of the terminal connector, which can reduce the space occupied by the connector and alleviate the space pressure of the circuit layout. At the same time, the rear ends of the upper and lower rows of terminals are electrically connected to multiple differential signal pairs, with 16 high-speed differential signal pairs, which can meet the application requirements of 25Gbps Ethernet 15m.

[0014] (ii) The flexibility, flame retardancy and tensile strength of the connecting wires are improved through the insulation layer and the shielding layer to prevent the connecting wires from being melted due to the high temperature of the terminal wire core in the small space, and to prevent the connecting wires from being easily broken.

[0029] When the wire cable core 101 is docked with the terminal connector 2, the multiple wire cable cores 101 of the two connecting wires 1 are distinguished, and then placed into the conductive plastic 203 on the upper row of terminals 201 and the lower row of terminals 202 respectively, and crimped to fix the wire cable core 101 in the conductive plastic 203. A double-layer side-by-side approach is adopted to achieve high integration of the terminal connector 2, which can reduce the space occupied by the connector and alleviate the space pressure of circuit layout.
