Problems solved by technology

[0003] In the existing wiring harness design of the distribution box, the wiring harness of the distribution box and the main wiring harness are usually designed in one piece. In the process of vehicle production design, if the layout of the distribution box changes, the distribution box needs to be redesigned. The branch of the box wiring harness has caused a lot of unnecessary repeated designs, wasting manpower and material resources

Abstract

The invention discloses a vehicle distribution box wire harness structure. A distribution box wire harness comprises a distribution box end wire harness and an electric appliance end wire harness, and the distribution box end wire harness is connected with the electric appliance end wire harness through a connector; one end of the distribution box end wire harness is connected with the distribution box, the other end of the distribution box end wire harness is connected with one end of the connector, the other end of the connector is connected with the electrical appliance end wire harness, and the other end of the electrical appliance end wire harness is connected with a wiring end of each electrical appliance. According to the design, the design cost can be reduced, the assembly efficiency is improved, and the modularization degree of equipment is improved.

Description

technical field [0001] The invention relates to a wiring harness structure of a vehicle distribution box, which is particularly suitable for simplifying the wiring harness structure of the vehicle distribution box and improving the modularization degree of the vehicle. Background technique [0002] The chassis and cab of commercial vehicles are usually of a split design. When the wiring harness of the cab and the chassis wiring harness are docked, a wiring device is required to connect and fix the main wiring harness of the chassis and the main wiring harness of the cab. Due to the large number of wiring harnesses and the use of many connectors, a junction box is usually designed to fix the connectors, and then the junction box is fixed on the front panel of the cab with bolts and nuts. The main wiring harness of the chassis is usually arranged inside the longitudinal beam, and some special electrical devices are arranged outside the longitudinal beam due to maintenance or l...
