Embodiment Construction

[0023] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to provide a comprehensive understanding of the present invention, many details are described below, but it will be apparent to those skilled in the art that the present invention can be practiced without these details. Known components, methods and processes will not be described in detail below.

[0024] A kind of CAN bus branch production method, when for mass production situation, such as figure 1 As shown, it specifically includes the following steps:

[0025] a) Assume that the CAN bus main line is the A cable;

[0026] b) Select the branch connection position on the cable A in advance and mark H, take the cable with a length of about 12mm from the point H as the midpoint to both ends of the cable, and remove the insulation jacket 1 of the cable with a length of 24mm;

[0027] c) Take the H point as the midpoint and take a 10mm long cable ...

Abstract

The invention discloses a manufacturing method of CAN (controller area network) bus branch batch production. The method comprises the following steps of: peeling the trunk of a CAN bus; folding the exposed wire along the center and then directly performing compression joint of a plug-in terminal; heating a shrinkage pipe to perform insulation protection, and mounting a plug-in jacket; for the after-sale restructuring condition, folding the exposed wire along the center and connecting the CAN bus extension branch in parallel by use of a compression joint terminal; heating the shrinkage pipe to perform insulation protection, and covering the restructured wire harness part with metal foil braided shield; and finally heating the shrinkage pipe as a cover to finish the manufacturing of the CAN bus branch. According to the invention, the manufacturing process of the CAN bus carrying branches in two conditions is simplified, the materials are saved, the expandability and reliability are improved, and the overall stability of the CAN bus network is guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle electrical technology, in particular to a manufacturing method for CAN bus branch mass production and an after-sales remanufacturing method. Background technique [0002] With the continuous development of vehicle technology, the number of vehicle-mounted devices using CAN communication continues to increase. CAN communication harnesses are used more and more frequently on vehicles, and there are more and more CAN bus branches. How to make CAN bus branches economically, efficiently and conveniently It has gradually become a difficult point in the design of vehicle electrical wiring harnesses. There are several problems in the production method of the traditional CAN bus branch: [0003] 1. The process is cumbersome. The traditional production method adopts the method of adding a branch harness after the main harness is disconnected and then pressing the three wires together. For each CAN bus branch, it is ...
