Abstract
Abstract An electrical connector is disclosed with means for producing a tactile signal when the connector members (10,12) are in a fully mated condition. An indicator (60) is movably mounted on the coupling nut (14) and is engageable by the opposed connector member (10) when the members are in a fully mated condition. An indicator element (60) is disposed in a passage (64) in the wall of the coupling nut (14) and a cam shaped surface (66) on the indicator element engages the starting end (72) of the thread (26) of the opposed member which causes it to move abruptly, i.e. "pop out" to a signal position when the full mate condition is reached.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
In a connector assembly of the type having first and second connector members adapted to be moved between a detached relationship and a fully mated relationship by a coupling nut rotatably mounted on the first connector member, each connector member including at least one terminal corresponding to a terminal on the other connector member, the corresponding terminals being coupled when the connector members are disposed in the fully mated relationship position, the improvement comprising: an indicator element movably supported by said coupling nut for movement between a reference position and a signal position; and a spring biasing said indicator element toward its reference position; said coupling nut comprising a cylindrical shell having forward and rearward faces and an internal wall, screw thread on the internal wall and a passage disposed in the internal wall, said passage extending axially from the rearward face of said coupling nut and being in alignment with a selected part of the second connector member; said second connector member having external screw thread adapted to be engaged by the said internal screw thread; said indicator element being slidably disposed in said passage and having an actuator portion engageable with the selected part of the second connector member when the connector members are in said fully mated relationship whereby as the coupling nut is rotated, the connector members are moved to the fully mated relationship and the indicator element is moved to the signal position when the terminals are coupled.

Claim 3
Dependent Claim
60 words
The invention as defined in claim 1 wherein said passage extends through said internal screw threads on said coupling nut, said selected part is the starting end of the external thread on the second connector member and said actuator portion is disposed so as to engage the starting end of the external thread when the fully mated condition is reached.
Claim 4
Dependent Claim
42 words
The invention as defined in claim 2 wherein said biasing spring comprises a spring wire having one portion seated on said first connector member and another portion operatively connected with said indicator element for urging said indicator element toward said reference position.
Claim 5
Dependent Claim
23 words
The invention as defined in claim 2 wherein said actuating portion includes a cam surface for causing abrupt movement of said indicator element.
Claim 6
Dependent Claim
142 words
In combination, a connector assembly comprising a pair of detachable connector members, a coupling nut rotatably mounted on one of the connector members, said connector members being movable by the coupling nut between a detached relationship and a fully mated relationship, an indicator element mounted in the coupling nut for providing a tactile signal when the connector members are in the fully mated relationship, the indicator element having an actuator portion for engaging the other connector member and a signal portion slidably retracted into a concealed position of the coupling nut when the members are not fully mated and extended into a signal position with the signal portion protruding beyond a surface of said coupling nut when the members are fully mated and a spring interconnecting the indicator element and the coupling nut for biasing said indicator element toward the retracted position.
