In the automotive industry, complex wiring harnesses consist of numerous individual wires, crimp contacts, and crucial connector housings. To ensure the proper functioning of all functions in the final product, wires must be precisely installed in their respective connector housings, ensuring that each component is in the correct position. The precise fit and stability of the connector housing are crucial for ensuring the stability and reliability of the entire wiring harness system.
The crimping contacts in the connector housing must achieve precise locking, which is the key to ensuring stable transmission of signals and power. To ensure that this requirement is met, polarity reversal testing can be used for inspection. This method involves introducing a test current into one pin of the connector and observing whether the current is smoothly and accurately output from the corresponding pin on the other end. Through this method, the locking status of the crimping contacts and the overall conductivity of the connector can be effectively verified.
If the actual situation is not like this, it indicates that at least one pressure contact point has not been correctly inserted into the designated cavity of the connector housing. To correct this error, the following steps must be performed: first, gently remove the incorrect crimping contact from the connector housing; Subsequently, reinsert it into the correct cavity position to ensure accurate matching with the casing.
Important Notice
If the crimping terminal is removed from the connector housing, it must not be bent or the locking function damaged. Bent or excessively bent latches can have a negative impact on the cavity gap. Damaged locking may result in failed mating of the connector housing.
be careful
Customers are prohibited from disassembling certain crimping joints. This ban mainly applies to crimping connections used in safety related components such as airbags. The reason for prohibiting disassembly is that the crimping contacts may be damaged during the disassembly process, so there is a possibility of connection failure due to initial damage when inserting again in the future.
