Therefore, to avoid the problem of connector retreat, the connector must first have sufficient retention force, and secondly, a reasonable terminal assembly specification should be formulated, and then the specification of the connector mating gap should be matched. If the above conditions are met, the terminal retreat problem can basically be avoided.
Seal failure
For wiring harness connectors in automotive wet areas, water resistance is an essential performance requirement for connectors in wet areas, such as engine compartments. The waterproof parts of connectors are mainly divided into two types: sealing rings and sealing plugs. The sealing ring is used to seal between the connectors, and the sealing plug is used to seal the wire and the inlet end of the connector. Sealing rings are further divided into axial seals and end face seals, and sealing plugs are further divided into individual sealing plugs and integral sealing plugs.
