When the terminals cannot be plugged together and need to be crimped again, the terminals should be pressed on the conductor and the insulating layer respectively, the conductor should not be crimped, and the insulating layer should not be pressed into the crimping part of the conductor. Wire conductors must not interfere with mating. The cross-section at the crimping point between the terminal and the wire using the crimping method shall meet the quality requirements. The connection between the terminal and the wire should be firm, and should not be damaged or disengaged under the specified tension, and the tension value should be less than the specified value.
