Abstract
The invention relates to a high-density, high-voltage-proof, multi-contact connector assembly. In order to overcome the problem of surface leakage currents or electrical discharges due to high voltage, the structure of terminals of the connector assembly has been changed in such a way as to provide male terminals with insulating ferrules, so that there will no longer be any gap for electric surface currents where two thermoplastic parts of the insulating body of a connector are pressed one part against the other. According to another embodiment, this problem is solved by forming an insulating body of the connector in one piece and inserting the terminals into openings being smaller than the diameter of the terminals, so that the undersized part of the opening is located in the depth of the opening and the creep distances are enlarged. Additionally, the terminals are provided with cutting barbs which, upon a rotation within the opening in the thermoplastic part, cut into the material and securely lock the terminals in place.
