Abstract
Abstract This invention relates to circular or cylindrical connectors comprising a male and a female member which are brought together to effect electrical interconnection between circuit components with subsequent locking of the members together by rotation of collar which is rotatably affixed to one of the members and has internal spiral grooves which engage pins affixed to the other of the connector members. In one embodiment the collar and pins are made from metal, and the pin-bearing member is made from plastic, and the torque-break resistance of the connector is improved through the use of L-shaped anchor strips to which the pins are affixed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
The circular electrical connector of the type wherein one of a pair of inter-engaging members has a revolvable circular outer collar having at least one interior helical groove attached for cooperative inter-engagement with pins affixed to the shell portion of the other of said pair of members to effect removable affixation of said members to each other, comprising at least one elongating backing strip affixed to and positioned interiorly of said shell portion with at least one of said pins affixed to a main portion of said strip, said strip extending inwardly of said shell from the point of affixation to said strip of said pin, the long axis of said strip being substantially parallel to the axis of the member to which it is affixed, said backing strip being L-shaped at a portion thereof inwardly of said shell portion from said point of affixation.
Claim 2
Dependent Claim
145 words
The circular electrical connector of the type wherein one of a pair of inter-engaging members has a revolvable circular outer collar having at least one interior helical groove attached for cooperative inter-engagement with pins affixed to the shell portion of the other of said pair of members to effect removable affixation of said members to each other, comprising at least one elongating backing strip affixed to and positioned interiorly of said shell portion with at least one of said pins affixed to a main portion of said strip, said strip extending inwardly of said shell from the point of affixation to said strip of said pin, the long axis of said strip being substantially parallel to the axis of the member to which it is affixed, said backing strip being L-shaped at a portion thereof inwardly of said shell portion from said point of affixation.
Claim 3
Dependent Claim
18 words
The device described in claim 1 wherein said L-shaped portion is formed at the end of said strip.
Claim 4
Dependent Claim
33 words
The device described in claim 1 wherein said L-shaped portion extends from the main portion of said strip in a direction away from the axis of the member with which it is associated.
Claim 5
Dependent Claim
35 words
The device described in claim 3 wherein said L-shaped portion extends from the main portion of said strip in a direction which is normal to the axis of the member with which it is associated.
