Claim 11

An electrical connector comprising complementary receptacle and plug connector members, each member comprising a hollow shell containing an insulating insert, each of said inserts supporting at least one electrical contact with the contacts of each member being adapted for axial connection in electrical engagement with a corresponding contact carried in the other member; a rotatable coupling ring carried by said plug and engageable with said receptacle for mating said connector members and holding the contacts therein in engagement; resilient means interposed between said coupling ring and said plug and having a predetermined range of axial deflection relative to said plug; said receptacle having a plurality of bayonet pins and said coupling ring having a corresponding plurality of pin-receiving tracks to provide a bayonet type releasable connection between said coupling ring and said receptacle, said coupling ring having limited axial movement relative to said plug so that upon connection of said coupling ring with said receptacle said coupling ring moves axially along said plug toward said receptacle thereby compressing said resilient means; and a plurality of detent means disposed between said coupling ring and said plug and having a predetermined range of radial movement, said detent means being equidistantly arranged about the circumference of said plug and said coupling ring having a corresponding plurality of interior axial slots extending forwardly from the rearward end of said coupling ring, said detent means being readily removable through said rearward end for replacement purposes without dismantling said connector when fully mated, and said detent means being releasably engageable with corresponding ones of said slots when said connector is fully mated to thereby substantially preclude rotational movement of said coupling ring relative to said plug except upon the application of deliberate external force to said coupling ring applied during disconnection of said members.

Claim 13

The electrical connector set forth in claim 9, wherein each of said detent means comprises a leaf spring having a base substantially fixed against radial movement relative to said plug, whereby the torque required to unseat said springs from said slots will be greater in the unmating direction of rotation fo said coupling ring than in the mating direction of rotation thereof.

Claim 14
