Embodiment 1

[0022] Embodiment 1: The wire harness of this embodiment has no branch structure.

[0023] First, use a steel rod with a diameter equal to that of the wire harness to make an under-vulcanized sleeve. Cover the steel rod with vulcanized rubber and heat and vulcanize it. Stop heating when it is not fully vulcanized. The vulcanized rubber forms an under-vulcanized sleeve on the surface of the steel rod, and then The undervulcanized casing is cut open and stripped from the rod. Cut the undervulcanized sleeve axially along a straight line.

[0024] The cable is straightened out through one-time forming tooling. The one-time forming tooling includes a slot plate and connectors at both ends. There is a straight slot in the center of the slot plate. There are notches at both ends of the straight slot. The notch slots are positioned along the side walls and bottom of both sides. The slot, the connector is installed at the notch, and after the connector is put into the notch, there is ...

Embodiment 2

[0025] Embodiment 2: The wiring harness of this embodiment has a branch structure

[0026] Use one-time forming tooling to position through the flange grooves of each connector, and design one-time forming tooling, including the slot plate and connectors. There are two positioning slots on the slot plate, one straight slot and one inclined slot. The distance between the positioning grooves of each connector flange is fixed, and the width of the middle wire harness groove is equal to the diameter of the wire harness. After the first connector is made and the glue is stacked, the second and third connectors are made. The cable semi-finished product starts from the first end and puts the connector and wire harness into the one-time forming tool step by step. When placing the second and third end connectors, push the connector back to place the flange plate in the groove of the positioning flange plate, and the second end is connected. The connector is used to install the branch p...

Abstract

The invention discloses a cable harness vulcanization method. The cable harness vulcanization method comprises the following steps of that vulcanized rubber is coated on a steel bar, heating and vulcanizing are carried out, heating is stopped when a complete vulcanization state is not reached, the vulcanized rubber forms an under-vulcanized sleeve pipe on the surface of the steel bar, the under-vulcanized sleeve pipe is cut off and stripped from the steel bar, finally, the vulcanized sleeve pipe sleeves a cable harness, and heating is carried out to finish vulcanization. According to the cableharness vulcanization method, the problems of non-uniform rubber coating and non-uniform stress deformation of wire harness can be solved, and the problem of vulcanization eccentricity of the cable wire harness is thoroughly solved from the aspect of a process method.

Description

technical field [0001] The invention belongs to the technical field of cable vulcanization, mainly relates to a treatment method for preventing eccentric vulcanization of multi-head cable harnesses, and belongs to the category of cable assembly. Background technique [0002] Due to the flexibility of the wire harness and the uneven pressure of the vulcanization process in the existing cable harness manufacturing method, the cable is prone to unqualified phenomena such as wire harness eccentricity and even wire leakage after vulcanization. The main reasons are: [0003] a. Due to the difference of each wire, the same trimming size will also cause length errors between the finished cables. Since the vulcanization process is based on the positioning of the connector flanges on both sides, the longer cable harness will go out of the mold during vulcanization molding. The redundant part is bent and deformed; [0004] b. The cable harness is composed of soft wires. It is difficul...
