Abstract
Abstract An electrical coupler comprises a receptacle member connected with an electric cable, and a plug member connected with an electric cable. They may be connected to permit electricity to flow between them in the usual fashion. Securing means prevent disconnection of the members caused by axial pulling on the cables. The securing means includes a strap with a flexible mid portion adapted to be wrapped around the cable connected with one of the members. The strap has end portions each with a stud projecting laterally therefrom, and there are a pair of stud receiving sockets in the other of said members. The strap may include a tab for facilitating removal of one of the studs from their sockets.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A portable electrical coupler subject to disconnection as a result of tensions applied to either or both ends of said electrical coupler which is used in conjunction with temporary wiring devices such as extension cords and the like comprising a receptacle member connected with a free and unconstrained electric cable which may be carried from place to place, a plug member connected with a free and unconstrained electric cable which may be carried from place to place and adapted to be inserted into said receptacle member to permit electricity to flow between said members, and securing means for preventing disconnection of said members caused by axial pulling on the cables, said securing means including a strap with a flexible mid portion adapted to be wrapped around the cable connected with one of said members and having end portions each with a stud projecting laterally therefrom, and means defining a pair of stud receiving sockets in the other of said members.
Claim 2
Dependent Claim
160 words
A portable electrical coupler subject to disconnection as a result of tensions applied to either or both ends of said electrical coupler which is used in conjunction with temporary wiring devices such as extension cords and the like comprising a receptacle member connected with a free and unconstrained electric cable which may be carried from place to place, a plug member connected with a free and unconstrained electric cable which may be carried from place to place and adapted to be inserted into said receptacle member to permit electricity to flow between said members, and securing means for preventing disconnection of said members caused by axial pulling on the cables, said securing means including a strap with a flexible mid portion adapted to be wrapped around the cable connected with one of said members and having end portions each with a stud projecting laterally therefrom, and means defining a pair of stud receiving sockets in the other of said members.
Claim 3
Dependent Claim
30 words
The electrical coupler as set forth in claim 1, wherein said end portions of said strap have flattened cross sections and said studs extend from a major side surface thereof.
Claim 4
Dependent Claim
21 words
The electrical coupler as set forth in claim 2, wherein said mid portion of said strap has a rounded cross section.
Claim 5
Dependent Claim
28 words
The electrical coupler as set forth in claim 2, wherein said strap includes a tab for facilitating removal of one of said studs from one of said sockets.
Claim 6
Dependent Claim
27 words
The electrical coupler as set forth in claim 4, wherein said tab includes an extension of one of said flat end portions beyond the stud projecting therefrom.
Claim 7
Dependent Claim
36 words
The electrical coupler as set forth in claim 1, further including surface means defining a pair of stud receiving sockets in said one member for receiving the studs when said securing means is not in use.
Claim 8
Dependent Claim
51 words
The electrical coupler as set forth in claim 1, wherein said sockets having inwardly extending shoulders around the entrance thereto, each of said studs having an enlarged head portion and a reduced cross section neck portion between said head portion and the respective one of said end portions of said strap.
Claim 9
Dependent Claim
19 words
The electrical coupler as set forth in claim 6, wherein said sockets are proportioned snugly to receive said studs.
Claim 10
Dependent Claim
35 words
The electrical coupler as set forth in claim 1, wherein said sockets have a major axis which lies in a plane transverse to the direction of insertion of said plug member into said receptacle member.
Claim 11
Dependent Claim
23 words
The electrical coupler as set forth in claim 1, wherein said mid portion is wrapped around a cable at least one complete revolution.
Claim 12
Dependent Claim
