Electrical plug

Claim 2

An electrical plug having an elongated plug body one end of which is adapted to be inserted into an electrical jack, said plug body having a cavity containing at least one electrical terminal, said cavity having a forward wall adjacent said end and a rear wall, a removable handle slidable axially and rotatable on said plug body and when mounted on said plug body covering said portion of said plug body containing said terminal including said cavity and said forward and rear walls, and mechanical interlocking means between said handle and said plug body adapted to lock said handle in fixed relationship with said plug body when said handle is mounted on said plug body and rotated a partial turn in one direction and to permit unlocking and slidable axial removal of said handle over said end from the portion of said plug body containing said terminal upon rotation a partial turn in the opposite direction, said forward wall containing a peripheral groove extending axially and said handle containing internal boss means adapted to move axially through said groove when said handle is slidably mounted axially over said portion of said plug body containing said terminal and to abut against the rear wall of said cavity so as to limit the inward movement of said handle.

Claim 3

A plug as claimed in claim 1 in which said handle is tubular and the portion of said plug body containing said peripheral groove contains a recess adjacent the periphery spaced from said groove, and said handle in the forward portion thereof contains internal boss means seating in said recess when said plug body and handle are interlocked and capable of sliding axially in said groove when rotated to the unlocked position.

Claim 4

A plug as claimed in claim 1 in which said handle Is slightly resilient and is made of electrically insulative polymeric plastic material.

Claim 5

A plug as claimed in claim 1 in which the forward end of said handle has a knurled area on its outer surface.

Claim 6

An electrical plug having an elongated plug body including an electrically conducting tip rod and sleeve electrically insulated from one another at one end, extending axially from an intermediate laterally extending offset portion and adapted to be inserted into an electrical jack, said offset portion extending rearwardly to form a generally tubular housing adapted to receive connecting means for connecting said tip rod to an electrical conductor, said housing being formed with an opening in a wall thereof through which said connecting means is accessible, a tubular handle slidably and rotatably mounted on said housing, and interlocking means between said handle and said housing including means to hold said handle in place and prevent axial movement thereof when said handle is rotated in one direction, means to release said handle and permit axial removal thereof over said tip rod and sleeve so as to expose said connecting means in said housing when said handle is rotated in the opposite direction, and internal boss mean spaced inwardly from the rear of said handle adapted to contact the rear side of said opening to limit the inward movement of said handle when it is mounted on said housing and moved axially inward over said opening.

Claim 7

An electrical plug having an elongated plug body including an electrically conducting tip rod and sleeve electrically insulated from one another at one end, extending axially from an intermediate laterally extending offset portion and adapted to be inserted into an electrical jack, said offset portion extending rearwardly to form a generally tubular housing adapted to receive connecting means for connecting said tip rod to an electrical conductor, said housing being formed with an opening in a wall thereof through which said connecting means is accessible, a tubular handle slidably and rotatably mounted on said housing, and interlocking means between said handle and said housing including means to hold said handle in place and prevent axial movement thereof when said handle is rotated in one direction, means to release said handle and permit axial removal thereof over said tip rod and sleeve so as to expose said connecting means in said housing when said handle is rotated in the opposite direction, and internal boss mean spaced inwardly from the rear of said handle adapted to contact the rear side of said opening to limit the inward movement of said handle when it is mounted on said housing and moved axially inward over said opening.

Claim 8

An electrical plug having an elongated plug body including an electrically conducting tip rod and sleeve electrically insulated from one another at one end, extending axially from an intermediate laterally extending offset portion and adapted to be inserted into an electrical jack, said offset portion extending rearwardly to form a generally tubular housing adapted to receive electrical conductors to be connected to said tip rod and sleeve, said housing having an opening in a wall thereof extending longitudinally from front to rear, connecting means for connecting said tip rod to one of said conductors in said housing and accessible through said opening, an electrically insulating tubular handle slidable axially and rotatably mounted on said housing, a peripheral groove extending axially in said offset portion, boss means on the inside of said handle spaced inwardly from the forward and rear portions of said handle and adapted to pass through said groove when said handle is mounted on said housing, said boss means at the rear portion of said handle being adapted to abut against the rear side of said opening to limit the inward movement of said handle, a recesses surface in said housing spaced inwardly from said offset portion and adapted to receive said boss means at the forward part of said handle when said handle is rotated whereby when said handle is rotated in one direction said boss means seats in said recess and forms an interlock holding said handle and housing together in fixed relationship and when rotated in the opposite direction until said boss means is opposite said groove said handle can be pulled longitudinally and slidably removed over said sleeve and tip rod thereby exposing said opening in said housing and rendering said connecting means accessible.

Claim 9

An electrical plug having an elongated plug body including an electrically conducting tip rod and sleeve electrically insulated from one another at one end, extending axially from an intermediate laterally extending offset portion and adapted to be inserted into an electrical jack, said offset portion extending rearwardly to form a generally tubular housing adapted to receive electrical conductors to be connected to said tip rod and sleeve, said housing having an opening in a wall thereof extending longitudinally from front to rear, connecting means for connecting said tip rod to one of said conductors in said housing and accessible through said opening, an electrically insulating tubular handle slidable axially and rotatably mounted on said housing, a peripheral groove extending axially in said offset portion, boss means on the inside of said handle spaced inwardly from the forward and rear portions of said handle and adapted to pass through said groove when said handle is mounted on said housing, said boss means at the rear portion of said handle being adapted to abut against the rear side of said opening to limit the inward movement of said handle, a recesses surface in said housing spaced inwardly from said offset portion and adapted to receive said boss means at the forward part of said handle when said handle is rotated whereby when said handle is rotated in one direction said boss means seats in said recess and forms an interlock holding said handle and housing together in fixed relationship and when rotated in the opposite direction until said boss means is opposite said groove said handle can be pulled longitudinally and slidably removed over said sleeve and tip rod thereby exposing said opening in said housing and rendering said connecting means accessible.
