Embodiment

[0035] The production process of a kind of new energy vehicle special wire harness that the present invention proposes, comprises the following steps:

[0036] S1. Preparatory work: prepare the materials required for wire harness production;

[0037] S2. Tangent: Check whether the size of the main conductor meets the design requirements. If it meets the requirements, locate the main conductor to be cut according to the design requirements. The ratio of the stripping length of the insulation skin at the tangent position to the stripping length required by the design is 2:3, perpendicular to the axis of the main conductor Cut the wire in the direction, and carry out visual inspection. The qualified standard is that there are no broken core wires, uneven core wires, damaged core wires, bent core wires, residual wire sheath, and unpeeled rubber;

[0038] S3. Pre-installation, crimping, stranding, ultrasonic welding: pre-thread the two main wires after tangent in step S2 into diffe...

Abstract

The invention discloses a production process of a special wire harness for a new energy automobile. The production process comprises the following steps: S1, preparing materials; S2, cutting lines; S3, allowing main wires to penetrate holes of a sheath sealing rear cover in advance, loading a sealing plug, dividing each main wire into an A end and a B end, crimping two main wire A end shielding rings, assembling a high-voltage sheath, crimping two main wire B end shielding rings, fixing two single auxiliary wires with the two main wires, then performing wire stranding, preassembling a black double-wall heat shrinkable tube, carrying out ultrasonic welding, and heating the black double-wall heat shrinkable tube, wherein one end close to the sealing plug is the main wire A end, the other endis the main wire B end; S4, winding glue and assembling; and S5, carrying out drawing test, conduction test, size inspection, appearance inspection and finished product packaging, and warehousing qualified finished products to finish the production process of the special wire harness for the new energy automobile. The production process provided by the invention is high in percent of pass, and the produced wire harness is excellent in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of wire harness production technology, in particular to a production technology of a special wire harness for new energy vehicles. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form advanced technical principles, new technologies, and new structures. Due to the advantages of saving fuel energy, less exhaust gas emissions, environmental friendliness, and high efficiency, new energy vehicles have been used more and more in recent years, and they have also become the development trend of future vehicles. The wiring harness is the carrier of the new energy vehicle circuit, which plays a vital role in the operation of the entire new energy vehicle. During the operation of new energy vehicles, especially electric vehicles, the power comes from the battery system,...
