Embodiment Construction

[0024] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0025] Please refer to figure 1 , this embodiment provides a semi-trailer and its semi-trailer wire harness 100 . The semi-trailer mainly includes a vehicle frame, a seven-pin socket 200, a five-pin socket 300 and two spiral connecting wires for connecting the power supply of the tractor. The seven-pin socket 200 and the five-pin socket 300 are fixedly arranged on the front beam 500 of the vehicle frame at intervals. Among them, both the seven-pin socket 200 and the five-pin socket 300 have a unified wiring standard, which is common for the electrical c...

Abstract

The invention provides a semitrailer wire harness. The semitrailer wire harnesses comprise a main wire harness and a branch wire harness, the main wire harness comprises a grounding wire, a pluralityof first wires, a plurality of second wires and a shell wrapping the wires into a whole. One wiring end of the grounding wire is divided into two strands, namely a first strand of grounding wire wiring end and a second strand of grounding wire wiring end; the wiring end of the first strand of grounding wire and the wiring ends of the plurality of first wires are used for being connected with a seven-core socket together so as to be connected with different lamps of a light assembly of the semitrailer; the branch wire harness comprises a plurality of third wires wrapped together; one end of each of the plurality of third wires is correspondingly connected with the wiring end of the second strand of grounding wire and the wiring ends of the plurality of second wires respectively; the other ends of the third wires are used for being connected with a five-core socket unit together so as to be connected with a braking system of the semitrailer. In this way, the semitrailer wire harnesses bind the wires used for supplying power to the light assembly and the brake system of the semitrailer together, and the high concentration of the wire harnesses is achieved.

Description

technical field [0001] The invention relates to the technical field of transport vehicles, in particular to a semi-trailer and its wiring harness. Background technique [0002] There are two types of semi-trailer electrical systems, which are used for lamps and brakes (antilockbrake system, ABS for short). Among them, the electrical interface form of lamps is based on the ISO 1185 standard, and the electrical interface form of the brake system is the ISO 7638 standard. The existing semi-trailer electrical appliances are artificially divided into two lines, the lamps use a seven-core wiring harness, and the braking system ABS uses a five-core wiring harness. [0003] The above-mentioned seven-core and five-core wire harnesses are fixed separately and distributed in distributed wiring. The number of wire harnesses is large, and the corresponding wire harness fixing brackets are also large, resulting in high cost of wire harnesses, and multiple grounding lines. The redundancy ...
