Every link of wiring harness design needs to be targeted. For example: design drawings, design samples, size and so on need to be revised and confirmed several times, so as to ensure the quality and safety of wiring harness. Wire harness design is a very rigorous work, the accuracy of its design, directly related to the performance and quality of the equipment.

The following is the wiring harness processing process need to understand some of the related wiring harness design accuracy and standard testing, so as to ensure the reliability of the quality of wiring harness products, so that the finished wiring harness zero defect so that customers can rest assured that the use of.

1, pressure contact should be firm, in the specified tension should not be damaged and off.

2. The surface insulation of the pressing joint should be good, and the conductor should not be broken.

3. The wiring harness wrapping material should be extended within 25mm from the end of the plastic case, except for a single wire.

4, voltage drop test requirements: terminal voltage drop detailed requirements refer to standard QC/T29106-1992.

5. The pressing of the connecting nail can use the U terminal pressing and ultrasonic fusion, etc., and the special machine shall be used for pressing.

6. Wear-resistant cloth tape should be used as a fixed wrapping outside the wiring harness connection point. In the area with waterproof requirements, the connecting nail should be protected by a heat-shrinkable tube jacket.

7. The label of the industrial wire harness should indicate the location of the connection and print it correctly and clearly. The label should be affixed at about 50mm from one end of the wire harness and stick firmly.

8. Minimum drawing force test requirements: the connection between the terminal and the wire should be firm, and the tension test should be carried out on the crimped wire harness at the rising speed of 200mm/min. The minimum drawing force should meet the requirements.

The designed wire harness products, but also through the proofing, test testing, technical feasibility of multiple aspects of research, can be mass production, so designed wire harness products to meet the needs of customers, but also in the production process can reduce the waste of raw materials, reduce production costs.

Techeng main products: power system current overload connectors, silicone wires, unmanned aerial vehicle/model battery wiring harness, auto emergency start power clamp, new energy vehicle wiring harness, electronic wiring harness, transfer and so on.
