Problems solved by technology

[0002] With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products are also increasing, and the failure rate of wiring harnesses is becoming more and more complex. The failure rate of wiring harnesses also increases accordingly; this requires improving the reliability and durability of wiring harnesses Performance, many people are more interested in the process and production of wire harnesses, but the existing wire harness technology and production failed to meet the needs of various electronic products, so that the manufactured wire harness products do not meet the needs, which is a problem for users bring loss
[0003] Due to the unscientific production process and unreasonable process parameters of the existing automobile wiring harness, especially the production process of the wear-and-tear connection harness, the production efficiency of the wiring harness is low, the pass rate is low, and the production cost of the enterprise remains high.

Embodiment 1

[0028] (1) Raw material reception: receive raw materials and check the quantity, batch, etc.;

[0029] (2) Raw material inspection: check whether the outer tube, outer diameter, number of single wires, single wire diameter and flame retardant performance of the wire are up to the standard. Uniformity, whether the insulation layer is cracked or bubbles, whether the insulation layer is close to the wire core and whether the wire core is oxidized, and whether the outer tube and color of the terminal are in compliance with the standards. Among them, the inspection content of the appearance of the terminal includes: Cracks, deformations, defects, burrs and corrosion phenomena, inspect the appearance, color and flame retardancy of the fiberglass casing, and inspect the appearance, color and flame retardancy of the sensor. Among them, the inspection contents of the appearance of the fiberglass casing and the sensor include: Free from flash, scratches, cracks and holes;

[0030] (3) ...

Embodiment 2

[0041] Embodiment 2: The rest is the same as Embodiment 1, except that in the step (10), the temperature and pressure of low-pressure injection molding are 175° C. and 11 bar, respectively.

Embodiment 3

[0042] Embodiment 3: The rest is the same as Embodiment 1, except that in the step (10), the temperature and pressure of low-pressure injection molding are 180° C. and 12 bar, respectively.

[0043] After the above process steps, the wire harness sample is taken out to be tested:

[0044]

[0045]

[0046] From the above data, it can be seen that the appearance quality of the produced wire harness products is good, there is no damage or cracking phenomenon, and the conduction rate meets the requirements of use, which is 100%. use.

Abstract

The present invention discloses a production method of an abrasion connection harness, and relates to the field of the automobile harness production technology. The production method comprises the 13 steps: reception of raw materials, examination of the raw materials, wire cutting and skinning, crimping, assembling, crimping, assembling, conduction test, low pressure molding and examination, conduction test, final inspection and package. Through the optimization of the production process, the adoption of a plurality of technologies and checking at each level, the production method of an abrasion connection harness is able to ensure that materials or provides produced by each process may reach best technology qualities; and moreover, through strict control of technological parameters, produced harness products are ensured to reach the high standard so that the rejection rate is reduced, and a pipeline operation step is employed in the crimping and assembling steps so that the production efficiency is increased, the cost of enterprises is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of automobile wiring harness production, in particular to a production method of a wearing and connecting wiring harness.
