Abstract
Abstract An insulating cord grip capable of being locked and unlocked by hand includes two cylindrical sections each having a hand grip on its outer surface. A locking of one of the sections relative to the other is achieved through relative rotary motion about a common axis to move one section axially with respect to the other. The locking means include a locking thread on the inner surface of one section and one on the outer surface of the other section. The two sections cooperate as they are rotated relative to one another with an internal cable clamping member which member tends to urge the sections apart axially with increasing force as the axial approach of the two sections urges the clamp against a contained cable with increasing force.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
A locking electrical connector comprising a cable terminal and a cable clamp, said cable terminal having an insulating housing and having conductive conductor terminal means within the housing, and said terminal having locking contacts extending from said conductor attachment terminals, said clamp and terminal being adapted to be and having means for being assembled together after cable conductors are connected to said conductor terminals, said clamp being made up of two insulating tubular parts having internal wedge means for bearing against a cable passing therethrough, a first tubular part having an external hand gripping surface at one section thereof and having an external thread at another section thereof, a second tubular part having an external hand gripping surface and having an internal thread, said internal wedge means being free to move generally radially in said tubular parts into and out of contact with a cable passing through said clamp, means for inducing radial movement of said wedge means responsive to axial movement of said two tubular parts, said two tubular parts being movable axially responsive to the engagement of said internal and external threads and rotation of said tubular parts relative to each other, and the threads of said tubular parts being of the self-locking Dardalet type.
Claim 2
Dependent Claim

A locking electrical connector comprising a cable terminal and a cable clamp, said cable terminal having an insulating housing and having conductive conductor terminal means within the housing, and said terminal having locking contacts extending from said conductor attachment terminals, said clamp and terminal being adapted to be and having means for being assembled together after cable conductors are connected to said conductor terminals, said clamp being made up of two insulating tubular parts having internal wedge means for bearing against a cable passing therethrough, a first tubular part having an external hand gripping surface at one section thereof and having an external thread at another section thereof, a second tubular part having an external hand gripping surface and having an internal thread, said internal wedge means being free to move generally radially in said tubular parts into and out of contact with a cable passing through said clamp, means for inducing radial movement of said wedge means responsive to axial movement of said two tubular parts, said two tubular parts being movable axially responsive to the engagement of said internal and external threads and rotation of said tubular parts relative to each other, and the threads of said tubular parts being of the self-locking Dardalet type.
Claim 3
Dependent Claim
11 words

Claim 4
Dependent Claim
21 words
The article of claim 1 wherein the angle of the Dardalet type threads is of the order of 12 to 15°.
Claim 5
Dependent Claim
18 words
The article of claim 2 wherein the plastic has a good balance of lubricity and surface binding properties.
