The electronic wiring harness is composed of terminal blocks, insulating wrapping materials, insulating sheaths and wires. It is a wiring component used to connect various electrical equipment in the circuit. In the field of electronic wiring harnesses, production quality is undoubtedly the top priority. Many details in the processing process may directly affect the use effect. In order to ensure the stable transmission of the wire harness, it is generally necessary to pay attention to these key points.
1. Wire dip tin/tinning time
After the wire is stripped, once the wire is stained with tin, too long heating time may cause the PVC to shrink due to heat. Therefore, control the tinning/tinning time not to be too long, and at the same time, ensure that the tin is evenly and completely covered.
2. Pay attention to the phenomenon of terminal PIN off when wearing rubber shell
When the plastic shell is worn, the terminal PIN often occurs. During the processing of the wire harness, it is necessary to pull back every time it is inserted into a hole to ensure that each terminal passing through the plastic shell is in good condition.
3. Ensure sufficient tension after crimping
If the tension cannot be reached after crimping, check whether the crimping range of the terminal and the wire conductor is suitable. Whether the material of the mold blade and the design of its structure are reasonable. Whether the material of the terminal meets the standard and so on.
