Abstract
Abstract An electrical connector having as parts a plug (11) and receptacle (10) which are releasably mated by selective rotation of a coupling ring (20) carried by one of said parts for interconnecting pin (34) and socket contacts respectively mounted within said connector parts, and including a first rigid insulator (31) in one of the connector parts within which the socket contact is located, and a second rigid insulator (32) in the other connector part including the pin contact extending from a surface therof; characterised by a body (36) of resilient insulative material located over the second rigid insulator (32) surface, said body having a thickness dimension measured along the pin contact (34) sufficient to compressingly contact the first rigid insulator (31) when the parts are mated and when the maximum tolerance spacing between the two insulators exists.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
137 words
An electrical connector having as parts a plug (11) and receptacle (10) which are releasably mated by selective rotation of a coupling ring (20) carried by one of said parts for interconnecting pin (34) and socket contacts respectively mounted within said connector parts, and including a first rigid insulator (31) in one of the connector parts within which the socket contact is located, and a second rigid insulator (32) in the other connector part including the pin contact extending from a surface therof; characterised by a body (36) of resilient insulative material located over the second rigid insulator (32) surface, said body having a thickness dimension measured along the pin contact (34) sufficient to compressingly contact the first rigid insulator (31) when the parts are mated and when the maximum tolerance spacing between the two insulators exists.
Claim 2
Dependent Claim
137 words
An electrical connector having as parts a plug (11) and receptacle (10) which are releasably mated by selective rotation of a coupling ring (20) carried by one of said parts for interconnecting pin (34) and socket contacts respectively mounted within said connector parts, and including a first rigid insulator (31) in one of the connector parts within which the socket contact is located, and a second rigid insulator (32) in the other connector part including the pin contact extending from a surface therof; characterised by a body (36) of resilient insulative material located over the second rigid insulator (32) surface, said body having a thickness dimension measured along the pin contact (34) sufficient to compressingly contact the first rigid insulator (31) when the parts are mated and when the maximum tolerance spacing between the two insulators exists.
Claim 3
Dependent Claim
60 words
An electrical connector as claimed in claim 1, in which the first insulator (31) includes an enlarged cavity in an outer surface aligned with the socket contact, and the insulative body (36) includes a protruding portion about the pin of such dimension as to enable compressing receipt within the cavity in said first insulator on mating of the connector parts.
Claim 4
Dependent Claim
25 words
An electrical connector as claimed in claim 2, in which the cavity is of circular plan and the insulative body protruding portion is generally conical.
Claim 5
Dependent Claim
36 words
An electrical connector as claimed in any preceding claim, in which the coupling ring (20) positions the plug and receptacle at a constant predetermined spacing on mating with the insulative body providing the sole tolerance compensation.
Claim 6
Dependent Claim
96 words
An electrical connector as claimed in any preceding claim in which the coupling ring (20) includes internal threads (28) which continuously engage a complementary set of threads (27) on the plug, a flange (33) which lockingly engages the receptacle during mating of the parts, selective rotation of said coupling ring when engaged with the receptacle positively driving the connector parts together, and spring means (39) carried by the coupling ring snapping against a surface of the plug when the coupling ring has rotated a predetermined amount thereby tactilely and audibly indicating mating of the connector parts.
Claim 7
Dependent Claim
34 words
An electrical connector as claimed in claim 5, in which means (38,46) rotating with the coupling ring engages further means (47) carried by the plug on the connector parts mating and unmating preventing override.
Claim 8
Dependent Claim
43 words
An electrical connector as claimed in claim 6, in which said means rotating with the coupling ring includes a washer (38) and projection (46) therefrom, and the means carried by the plug includes a slot (47) within which the washer projection is received.
Claim 9
Dependent Claim
40 words
An electrical connector as claimed in any preceding claim in which a coupling ring to plug interlock means (50-58) is released by the receptacle being received within the plug enabling rotation of the coupling housing with respect to the plug.
Claim 10
Dependent Claim
89 words
An electrical connector as claimed in any preceding claim in which the coupling ring flange (33) has at least one keyway (25) formed therein aligned with a keyway (49) formed in the plug when the plug is released from the receptacle, at which time spring-loaded means (52,53) located generally in the plug keyway obstruct rotation of the coupling ring with respect to the plug, said spring-loaded means being moved on receipt of the receptacle within the plug to a position allowing the coupling ring to rotate about the plug.
Claim 11
Dependent Claim
35 words
An electrical connector as claimed in claim 9, in which a key (14) on the receptacle engages the spring-loaded means (52,53) on said receptacle entering the plug moving said spring-loaded means to the release position.
Claim 12
Dependent Claim
30 words
An electrical connector as claimed in claim 10, in which the spring-loaded means (52,53) returns to the coupling ring rotation obstructing relation on the receptacle being removed from the plug.
Claim 13
Dependent Claim
109 words
An electrical connector as claimed in claim 9, 10 or 11 in which there are two keyways (49,25) provided in the plug and coupling ring at substantially 180 degree angular spacing, said spring-loaded means including an annular interlock sleeve (50) located between the coupling ring and plug with first and second actuators (52,53) mounted thereon extending into the respective keyways, and a spring (64) urging the interlock sleeve toward the plug open end, the receptacle including first and second keys (14) so dimensioned and located as to fit into the keyways on mating of the plug and receptacle and engage both the actuators releasing the coupling ring for rotation.
