Electrical connector assembly
First Claim
1. An electrical connector assembly including a pair of connector housings which are moveable along a primary axis from an uncoupled position to a coupled position, a coupling ring rotatably mounted to one of said connector housings for drawing the other connector housing therewithin, and means for resisting rotation of the coupling ring, said resisting means characterized in that:
- one of said connector housings includes a first surface (72);
said coupling ring includes a second surface (82) disposed in confronting relation to the first surface (72);
a plurality of equally spaced protuberances (74) extending outwardly from one of said surfaces (72), each said protuberance being comprised of an elastically deformable material anda plurality of equally spaced sockets (84) extending inwardly from the other of said surfaces (82), each of said protuberances (74) and said sockets (84) being generally hemispherically shaped, the protuberances (74) being received within respective of the sockets (84) and each being required to elastically deform to advance into its next adjacent socket upon application of an external torque tending to rotate the coupling ring, whereby as the coupling ring is rotated each protuberance elastically deforms and advances to its next succeeding socket.

Abstract
An electrical connector assembly (100) includes a coupling ring (50) for connecting together two connector housings (10, 20) and self-contained means for resisting rotation of the coupling ring relative to the connector housing (20) to which it is rotatably mounted. The resisting means includes coupling ring (50) and connector housing (20) respectively, frusto-conical surfaces (72, 82) with protuberances (74) and sockets (84), in faced relation, the protuberances being adapted to be received in and rotated to succeeding sockets. The compressible plastic is such that as the housings are drawn into tight engagement the protuberances on the coupling ring engage the plastic surface on the other connector housing (10), causing the protuberances and surfaces to elastically compress. The tapered shoulders enhance engagement therebetween to increase the frictional forces resisting the vibration and radially locates the coupling ring with respect to the connector components to minimize hammering in shock prone environments resulting from radial clearances therebetween.

11. An electrical connector assembly including a pair of electrical connector housings (10, 20) which are movable from a decoupled position to a mated position, a coupling ring (50) mounted for rotation on one housing (20) and arranged to be threaded on the other housing (10) to move and couple the housings together in the mated position, and means (72, 74, 82, 84) operative between said coupling ring and one of said housings for resisting unwanted rotation of the coupling ring, said assembly characterized in that:
-
said one housing (20) includes a first portion (70) having a frusto-conical surface (72) comprised of an elastically deformable material; said coupling ring (50) includes a second portion (80) comprised of an elastically deformable material having a frusto-conical surface (82) confronting the first portion (70); a plurality of sockets (84) disposed in one of said frusto-conical surfaces (82); and an integral protuberance (74) comprised of an elastically deformable material extending outwardly from the other of said frusto-conical surfaces (72), said protuberance being received in one of said plurality of sockets and required to undergo elastic deformation to succeed into other of said sockets upon application of an external torque tending to rotate the coupling ring, whereby as external torque is applied to the coupling ring the first and second surfaces and the protuberance elastically deform and the protuberance is constrained to succeed from the one socket to the next socket. - View Dependent Claims (12, 13)
