Retention: The mating retention of high-voltage connections and the retention of plastic parts on conductive terminals are important considerations. Many high-voltage connectors in the industry have defects such as lack of quantification of buckle retention force and torque of buckle, so there is a lot of room for optimization.
Secondary lock: The high-voltage connector needs to have a secondary locking mechanism. The secondary locking mechanism requires a certain starting force (usually not greater than 40N). The main purpose is to prevent the high-voltage connector from being damaged by external forces such as transportation and handling. And accidentally opened.
Error proofing and marking: High-voltage connectors need to have mechanical error proofing function, that is, to meet a certain force value for wrong insertion of plugs and sockets (error proofing force > 3 times the insertion force, usually at least 80N), and the terminals will not be damaged in any way .
In addition, error-proof designs such as color identification and key identification are usually required.
Vibration, shock performance: High voltage connectors must be designed to meet certain mechanical loads. In general, vibration level 3 is required.
Crimping strength: High voltage connector terminals and cables need to meet a certain crimping strength, so as to maintain stable crimping resistance under temperature cycle conditions for a long time, and at the same time avoid crimping separation caused by inertial forces such as vibration and swing of micro-terminal cables .
