Abstract
Disclosed is an improved multi-pin type of water proof electric connector which is guaranteed free of shortcircuit between adjacent pin-and-contact piece connections even if water should invade to any pin-and-connector piece connection through the very small gap between the conductor and the insulation sheath of the wire by the capillary action. The electric connector comprises a male half having contact pieces and a female half having pin terminals in its cavity, and a seal member placed in the space which is to be formed between the outer surface of the plug housing and the inside surface of the socket housing when the male and female halves are coupled. The plug housing has a plurality of hollow protrusions each containing a contact piece, and the seal member encircles each of the protrusions, thereby sealing each pin-and-contact piece connection independently from adjacent pin-and-contact piece connections when the male and female halves are mated.
