ABSTRACT:
A locking electrical cord connector includes a two piece housing formed from electrically non-conductive material. A pair of conductors are received in the housing. Each conductor includes a male electrical contact and a female electrical contact. Two locking mechanisms are also provided in the housing. The first cooperates with the male electrical contacts for locking the male electrical contacts to a receptacle. The second cooperates with the female electrical contacts for locking the female electrical contact to a plug of another electrical appliance. More particularly, each of the locking mechanisms includes a spring metal element. The distal end of each spring metal element associated with a male contact is bradded to the male contact. The distal end of each spring metal element associated with a female contact is fixed in a notch in the housing. The proximal ends of the spring metal elements are received in slots cut in opposed slide blocks. These slide blocks are held for limited reciprocal movement within a chamber in the housing. A lever controlled cam actuator cooperates with the slide blocks and allows the locking cord connector to be locked and unlocked. When locked, the spring metal elements bow to provide frictional binding action.
