● The voltage selection needs to be matched: the rated voltage of the vehicle after the load calculation should be less than or equal to the rated voltage of the connector. If the working voltage of the vehicle exceeds the rated voltage of the connector and runs for a long time, the electrical connector has the risk of creepage and ablation.
● The current selection needs to be matched: the rated current of the vehicle after the load calculation should be less than or equal to the rated current of the connector. If the working current of the vehicle exceeds the rated current of the connector and runs for a long time, the electrical connector has the risk of overload and ablation.

● The whole vehicle needs flexible wiring: for the whole vehicle wiring, each OEM has requirements for bending radius and slack;
For use cases, it is recommended that after the wiring harness is assembled, the connector terminals themselves will not be stressed. Only when the wiring harness as a whole is subjected to vibration, impact and relative displacement of the vehicle body due to the operation of the vehicle, the purpose of strain relief is achieved through the flexibility of the wiring harness, even if a little strain is transmitted to the connection. Connector terminals, the resulting stress does not exceed the design retention force of the terminal in the connector.
