Abstract
Abstract A fiber optic modular connector system is disclosed which includes a receptacle connector (30) and a locking leaf spring (17) having a locking tang (17c) mounted on the receptacle connector. The connector system further includes a removable plug connector housing (19) carrying a rotatable coupling ring (23) for selective coupling with the receptacle connector. The coupling ring includes external splines (25) for accepting a connector installation and removal tubular wrench (50), and further includes a plurality of notches (27) for cooperating with the locking leaf spring to provide a ratchet mechanism. The notches on the coupling ring and the locking leaf spring on the receptable connector allow the coupling ring to be rotated in a first direction, and prevent rotation in a second direction when the locking tang of the leaf spring is engaged with one of the notches on the coupling ring. The disclosed connector system further includes a connector installation and removal tubular wrench (50) which has an elongated housing (35) and an internally splined socket (39) for selectively meshing with and engaging the external splines of the plug connector coupling ring. An elongated slot (47) extending from the end of the socket along the housing is provided to allow the tubular wrench to be placed over a removable plug connector having a fiber optic cable connected thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
198 words
A connector system comprising: a receptacle connector; a removable plug connector housing; a coupling ring rotatably mounted on said plug connector housing for selective coupling with said receptacle connector; interlocking means about said coupling ring to render said coupling ring selectively engageable by a tubular wrench; locking means on said receptacle connector and said coupling ring for cooperatively allowing relative rotation in a first direction between said coupling ring and said receptacle connector, and for preventing relative rotation in a second direction between said coupling ring and said receptacle connector when said locking means is enabled; and a tubular wrench having: an elongated cylindrical housing; a socket at one end of said housing for selectively engaging said interlocking means about said coupling ring and further having unlocking means for disabling said locking means, said interlocking means about said coupling ring comprising means about said coupling ring for slidably engaging said tubular wrench socket, and said socket including means for meshing with said slidably engaging means about said coupling ring to provide a rotationally interlocked engagement between said tubular wrench and said coupling ring; and an elongated slot axially extending from the end of said socket along said housing.
Claim 2
Dependent Claim
198 words
