Abstract
Abstract A coaxial electrical connector is disclosed of the type in which a bayonet coupling nut on one connector member mates with bayonet pins on the mating connector member. A rotatable ring on the one connector member has a threaded engagement with the bayonet coupling nut. The wave spring normally associated with a bayonet coupling nut is eliminated. After the nut is engaged with the mating connector member, the ring is rotated to shift the connector shell or outer conductor forwardly until it bottoms out against the mating shell thereby extending the upper frequency limit of the connector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
An electrical connector member for a coaxial cable having inner and outer conductors comprising: a conductive shell having a forward mating end and a rear termination end adapted to be connected to the outer conductor of the cable; an insulator in said shell containing a center contact adapted to be connected to the inner conductor of the cable; a ring rotatably mounted on said shell, said ring embodying a forwardly facing shoulder engaging a rearwardly facing shoulder on said shell; a rotatable bayonet coupling nut in front of said ring; and said ring and nut having a threaded connection therebetween whereby rotation of said ring in one direction will cause said shell and nut to move axially toward each other after said nut is coupled to a mating connector member.
Claim 2
Dependent Claim
130 words
An electrical connector member for a coaxial cable having inner and outer conductors comprising: a conductive shell having a forward mating end and a rear termination end adapted to be connected to the outer conductor of the cable; an insulator in said shell containing a center contact adapted to be connected to the inner conductor of the cable; a ring rotatably mounted on said shell, said ring embodying a forwardly facing shoulder engaging a rearwardly facing shoulder on said shell; a rotatable bayonet coupling nut in front of said ring; and said ring and nut having a threaded connection therebetween whereby rotation of said ring in one direction will cause said shell and nut to move axially toward each other after said nut is coupled to a mating connector member.
Claim 3
Dependent Claim
33 words
An electrical connector member as set forth in claim 1 wherein: the forward end of said ring is internally threaded and the rear of said nut is externally threaded providing said threaded connection.
Claim 4
Dependent Claim
62 words
An electrical connector member as set forth in claim 1 wherein: overlapping annular grooves are formed in said ring and said shell; and a retaining ring is carried by one of said grooves and extends into the other groove, the front face of said retaining ring and the front edge of said other groove providing said forwardly and rearwardly facing shoulders, respectively.
Claim 5
Dependent Claim
154 words
An electrical connector for coaxial cables comprising: first and second mating connector members each adapted to be connected to a coaxial cable; each said connector member comprising a conductive shell having an insulator therein containing a center contact matable with the center contact of the other connector member; said shells having forwardly facing surfaces thereon adapted to abut each other after said connector members are initially mated; one of said shells having a bayonet coupling nut thereon for connection with bayonet pins on the other shell; a ring rotatably mounted on said one shell behind said nut, said ring having a forwardly facing shoulder engaging a rearwardly facing shoulder on said one shell; and said ring and nut having a threaded connection therebetween whereby rotation of said ring in one direction will cause said shell surfaces to abut after said connector members are initially mated by engagement of said bayonet pins with said nut.
Claim 6
Dependent Claim
154 words
An electrical connector for coaxial cables comprising: first and second mating connector members each adapted to be connected to a coaxial cable; each said connector member comprising a conductive shell having an insulator therein containing a center contact matable with the center contact of the other connector member; said shells having forwardly facing surfaces thereon adapted to abut each other after said connector members are initially mated; one of said shells having a bayonet coupling nut thereon for connection with bayonet pins on the other shell; a ring rotatably mounted on said one shell behind said nut, said ring having a forwardly facing shoulder engaging a rearwardly facing shoulder on said one shell; and said ring and nut having a threaded connection therebetween whereby rotation of said ring in one direction will cause said shell surfaces to abut after said connector members are initially mated by engagement of said bayonet pins with said nut.
