How is a good harness designed Techeng Electronics

Each link of harness design needs to be targeted. For example, the design drawings, design samples, dimensions, etc. need to be modified and confirmed for many times, so as to ensure the quality and safety of the harness. Harness design is a very rigorous work. The accuracy of its design is directly related to the performance and quality of equipment.

The following are some relevant accuracy of harness design and test standards that need to be understood in the process of harness processing, so as to ensure the reliability of harness product quality, achieve zero defects of finished harness products and let customers rest assured.

1. The pressure contact shall be firm and shall not be damaged or disconnected under the specified tension.

2. The surface insulation of the crimping part shall be good, and the conductor shall not be broken.

3. The harness binding material shall be extended within 25mm from the tail of the plastic shell, except for a single conductor.

4. Voltage drop test requirements: refer to standard QC / t29106-1992 for detailed requirements of terminal voltage drop.

5. U-shaped terminal crimping and ultrasonic fusion can be used for crimping of connecting nails, and special machine shall be used for crimping.

6. Wear resistant cloth woven tape shall be used for fixing and binding outside the harness connection point. In the area with waterproof requirements, the connecting nail shall be protected by a heat shrinkable tube jacket. The temperature resistance of the heat shrinkable tube shall be - 40 ℃ - + 100 ℃.

7. The industrial harness label shall indicate the connection position and print correctly and clearly. The label shall be pasted about 50mm away from one end of the harness and pasted firmly.

8. Minimum pull-out force test requirements: the connection between the terminal and the wire shall be firm. Carry out the pull-out test on the crimped harness at the rising speed of 200mm / min, and the minimum pull-out force shall meet the regulations.

The designed harness products can only be mass produced through proofing, test and Research on technical feasibility. In this way, the designed harness products can meet the needs of customers, and can also reduce the waste of raw materials and production costs in the production process.

Techeng's main products: power system current overload connector, silica gel wire, UAV / aircraft model battery connection harness, automobile emergency start power clip, new energy automobile harness, electronic harness, adapter, etc.
