Abstract: A waterproof electrical connector for connecting electrical conductors. The connector includes male and female electrical contact members which are adapted to be connected to different electrical conductors. In addition, the male and female electrical contact members comprise male and female complementary plugs which are adapted to mate with each other to create an electrical connection. Also provided are male and female elastic, insulating blocks in which the male and female members are respectively embedded. Male and female housings house the male and female blocks, respectively. A first sealing means seals the end of the male and female blocks nearest the electrical connection from the infiltration of water. The first sealing means is pressure-actuated and comprises a concave cup at the end of each block. A second sealing means seals the male and female housings against the infiltration of water therethrough is also provided and it is also pressure-actuated.
