Locking electrical receptacle
First Claim
1. An apparatus for use in securing an electrical connection, said electrical connection being formed by a plug including prongs of a male assembly extending from a housing of said male assembly and a receptacle including sockets of a female assembly, wherein said electrical connection is broken by withdrawal of said prongs from said sockets, said apparatus comprising:
- a plug mating structure of said plug for receipt within a receptacle mating structure of said receptacle;
at least one tab structure having a pivoting end opposite a free end and extending outward from said plug mating structure of said plug for receipt within a recess formed on an internal wall of said receptacle mating structure of said receptacle, wherein said tab structure is moveable between a lock configuration in which a portion of said tab structure is disposed within said recess and a release configuration in which said portion is withdrawn from said recess, wherein said pivoting end of said tab structure is disposed further from said housing than said free end and said free end is disposed external to the plug mating structure when in the lock configuration, and wherein said tab structure is biased toward said lock configuration such that said tab structure automatically becomes disposed within said recess when said plug is fully inserted into said receptacle; and
a release mechanism comprising a button accessible by a user external to said housing for moving said tab structure to said release configuration to facilitate withdrawal of said plug from said receptacle.

Abstract
A method and apparatus for securing an electrical connection formed by a mating structure including prongs of a male assembly and receptacles of a female assembly are provided. In certain embodiments, the electrical connection can be secured by frictional engagement between the plug and receptacle housings. This can be accomplished by forcing a wedge into an interface between the housings or expanding a locking element, such as an elastomeric ring, into the interface. Such locking and releasing of the secure connection can be actuated using a locking nut.

13. An apparatus for use in securing an electrical connection, said electrical connection being formed by a plug including prongs of a male assembly and a receptacle including sockets of a female assembly, wherein said electrical connection is broken by withdrawal of said prongs from said sockets, said apparatus comprising:
-
a plug mating structure of said plug for receipt within a receptacle mating structure of said receptacle; at least one tab structure extending outward from said plug mating structure of said plug for receipt within an aperture passing through an internal wall of said receptacle mating structure of said receptacle, wherein said tab structure is moveable between a lock configuration in which a portion of said tab structure is disposed within said aperture and a release configuration in which said portion is withdrawn from said aperture; and a release mechanism for moving said tab structure to said release configuration to facilitate withdrawal of said plug from said receptacle.
