Electrical connector having a coupling indicator

Claim 2

An electrical connector assembly of the type comprising a plug member and a receptacle member each having electrical terminals secured in passageways extending therethrough, a coupling member rotatingly mounted on the plug member and having threads on an internal surface for threadable engagement with threads on an external surface of the receptacle member to mate the plug member and receptacle member together and the electrical terminals therein, and a spring member secured onto said plug member retaining said coupling member onto said plug member, characterized in that: said spring member has a hammer section and a detent section adjacent each other; said coupling member has an anvil section and a pin member, said pin member rides along an outer surface of said spring member as the threads of said coupling member are threadably moving along the threads of said receptacle member and engages said detent section causing said spring member to be radially and circumferentially deformed thereby cocking said hammer section which forcefully strikes said anvil section as said pin member moves into a relief area between said hammer section and said detent section resulting in a tactile, audible and visible indication that the connector assembly is completely mated.

Claim 3

An electrical connector assembly as set forth in claim 1, characterized in that said plug member has a groove in which said spring member is disposed and a recess in which a securing section of said spring member extends thereby preventing said spring member from rotating relative to said plug member.

Claim 4

An electrical connector assembly as set forth in claim 2, characterized in that said securing section has a J-shape configuration such that a free end thereof engages an inner surface of an annular shoulder of said coupling member.

Claim 5

An electrical connector assembly as set forth in claim 1, characterized in that said spring member has another detent section adjacent said hammer section, said other detent section having another relief area in which said pin member is disposed when said coupling member is in an uncoupled position.

Claim 6

An electrical connector assembly as set forth in claim 4, characterized in that said spring member along an inside surface extending along said detent sections and said hammer section has a radius greater than the radius of the remaining inside surface thereof.

Claim 7

An electrical connector assembly as set forth in claim 1, characterized in that said plug member and said receptacle member include metal shells having dielectric inserts carrying said electrical terminals secured therein.

Claim 8

An electrical connector assembly as set forth in claim 6, characterized in that said metal shells and said inserts having mating keys and keyways to assure proper mating engagement therebetween.

Claim 9

An electrical connector assembly as set forth in claim 7, characterized in that said inserts are angularly oriented relative to said metal shells.

Claim 10

A separable electrical connector comprising: first and second shells connectable in alignment along a common axis; interfitting keying means on the shells to allow their axial approach and retreat relative to each other; an insulating insert mounted within each shell; cooperating pin and receptacle-type electrical terminals, said pin terminals mounted in one of said inserts and said receptacle terminals mounted in said other insert, said pin and terminal receptacles connectable in mated relationship; and means for connecting and disconnecting the first and second shells together, said means comprising: a coupling ring rotatably mounted on one of said shells; interfitting thread means in said ring and on said other shell; a retaining ring mounted on the one of said shells retaining said coupling ring thereon; and said coupling ring having an anvil section and a pin member adjacent to said anvil section; said retaining ring defining a spring member having a hammer section and a detent section thereto, said pin member moving along said spring member as said coupling ring is rotated causing said thread means to draw said shells, inserts and terminals together in mated relationship, and, when said pin member engages said detent section, said spring member is radially and circumferentially deformed thereby cocking said hammer section which forcefully strikes said anvil section as said pin member moves free of said detent section resulting in a tactile, audible and visible indication that the connector is completely mated.

Claim 11

A separable electrical connector comprising: first and second shells connectable in alignment along a common axis; interfitting keying means on the shells to allow their axial approach and retreat relative to each other; an insulating insert mounted within each shell; cooperating pin and receptacle-type electrical terminals, said pin terminals mounted in one of said inserts and said receptacle terminals mounted in said other insert, said pin and terminal receptacles connectable in mated relationship; and means for connecting and disconnecting the first and second shells together, said means comprising: a coupling ring rotatably mounted on one of said shells; interfitting thread means in said ring and on said other shell; a retaining ring mounted on the one of said shells retaining said coupling ring thereon; and said coupling ring having an anvil section and a pin member adjacent to said anvil section; said retaining ring defining a spring member having a hammer section and a detent section thereto, said pin member moving along said spring member as said coupling ring is rotated causing said thread means to draw said shells, inserts and terminals together in mated relationship, and, when said pin member engages said detent section, said spring member is radially and circumferentially deformed thereby cocking said hammer section which forcefully strikes said anvil section as said pin member moves free of said detent section resulting in a tactile, audible and visible indication that the connector is completely mated.

Claim 12

A separable electrical connector as set forth in claim 9 wherein said inserts include interfitting keying means and said inserts are positionable relative to their respective shells so that said shells and their respective inserts are matably engagable.

Claim 13

A separable electrical connector as set forth in claim 9 wherein said first shell and its insert have forward sections spaced from each other defining an annular space therebetween; said second shell and its insert have hood sections with the shell hood section covering the insert forward section and the insert hood section being disposed within said annular space when said shells and inserts are mated.

Claim 14

A separable electrical connector as set forth in claim 9 wherein said spring member includes another detent section adjacent said hammer section for indicating an uncoupled condition of the connector.
