Abstract
Abstract A push-on pull-off connector member 30 for coupling to a standard bayonet receptacle 10 has three equi-spaced circumferential slots 36 for receiving the bayonet pins 20 of the receptacle 10. Spring rings 40 in circular recesses 38 opening into the slots 36 from each side retain the pins 20. The recesses 38 are easily formed, for example, by milling. The coupled connector resists a weak uncoupling force but separates under a strong force, and can provide a snatch-disconnect facility. In alternative embodiments, each slot 36 has a single circular ring (FIG. 6), two spring rings are formed at each end of a single member (FIG. 4), the rings have inwardly-directed tangs for ease of fitting and removal (FIG. 5), or the spring rings are parts of question-mark shaped members (FIG. 7).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
An electrical connector member comprising a generally cylindrical shell member forming a housing for one or more electrical contacts and being provided with means for retaining the connector member on a mating connector member which carries generally radial bayonet pins, the said means including an axial passage for receiving each bayonet pin, and being such that the connector member can be coupled to and uncoupled from a mating connector member carrying bayonet pins by a sufficient axial force but is retained in the coupled condition against a weak force in the uncoupling direction, characterised in that the said means includes a plurality of resilient members each having a plurality of at least partially circular portions, each said circular portion being accommodated in a respective recess and each recess intersecting with the associated passage such that the said portions extend partially into the passage.
Claim 2
Dependent Claim
143 words
An electrical connector member comprising a generally cylindrical shell member forming a housing for one or more electrical contacts and being provided with means for retaining the connector member on a mating connector member which carries generally radial bayonet pins, the said means including an axial passage for receiving each bayonet pin, and being such that the connector member can be coupled to and uncoupled from a mating connector member carrying bayonet pins by a sufficient axial force but is retained in the coupled condition against a weak force in the uncoupling direction, characterised in that the said means includes a plurality of resilient members each having a plurality of at least partially circular portions, each said circular portion being accommodated in a respective recess and each recess intersecting with the associated passage such that the said portions extend partially into the passage.
Claim 3
Dependent Claim
18 words
A connector member according to claim 1, in which the a circular portions are portions of circular spring.
Claim 4
Dependent Claim
28 words
A connector member according to claim 1, in which each circular portion is connected to another circular portion by means extending around the periphery of the connector member.
Claim 5
Dependent Claim
35 words
A connector member according to claim 1, in which each circular portion is a loop portion of resilient member of question-mark shape having its stem portion seated in a peripheral groove of the connector member.
Claim 6
Dependent Claim
39 words
A connector member according to claim 4, in which the loop portion is shaped such that the force required to couple the connector member onto a mating connector member is different from the force required to uncouple the members.
Claim 7
Dependent Claim
21 words
A connector member according to claim 1, in which the circular portions are portions of circular rings of moulded plastics material.
Claim 8
Dependent Claim
28 words
A connector member according to claim 1, in which the circular portions are portions of circular rings having inwardly-directed radial portions thereon to facilitate handling of the rings.
Claim 9
Dependent Claim
17 words
