Abstract
An SC connector includes a back body having a locking member and a front body having a locking member and a buffer back post. The front body is disposed in the back body and the back body locking member and front body locking member engage to provide a one-piece ferrule buffer back post connector assembly.
Claims23
A fiber optic connector comprising:
- a back body having a first opening and a second opening and a bore aligned along a longitudinal axis of said back body and extending between the first and second openings, said back body further including:
- a back body locking member disposed on said back body proximate the first end of said back body;
- and
- a first shoulder region extending into the bore of said back body at a first predetermined distance from the first opening of said back body;
- and
- a front body having a first end having an aperture therein and a second end disposed in the bore of said back body, said front body further including:
- a back post projecting from the second end of said front body into the bore of said back body;
- and
- a front body locking member provided as a flange projecting from an outer surface of said front body wherein said front body locking member and said back body locking member engage to secure together said front body and said back body.

A fiber optic connector comprising:
- a back body having a first opening and a second opening and a bore extending between the first and second openings;
- and
- a front body having a first end having an aperture therein and a second end, said front body further including a back post projecting from the second end of said front body;
- wherein said back body further includes first means for engaging said front body and said front body includes second means for engaging said back body;

A method of terminating a fiber optic cable comprising the steps of:
- (a) inserting a ferrule into a first end of a front body with a second opposite end of the front body having a buffer back post projecting therefrom;
- (b) sliding a spring over the buffer back post;
- (c) engaging the spring to the front body such that the spring is secured over the buffer back post;
- (d) coupling a back body to the front body such that the back body surrounds the buffer back post and a first end of the spring contacts a first surface of the back body;
- (e) disposing an optical fiber through the ferrule;
- and
- (f) securing the optical fiber in the ferrule.

- a fiber optic cable, said fiber optic cable including:
- a shield provided from aramid fiber;
- a buffer;
- and
- an optical fiber;
- a connector coupled to said fiber optic cable, said connector including:
- a back body having a first opening and a second opening and a bore extending between the first and second openings of said back body, a locking member disposed on the first end of said back body and a first shoulder region extending into the bore of said back body at a first predetermined distance from the first opening of said back body;
- and
- a front body having a first end and a second end wherein the first end of said front body has an aperture therein, and the second end of said front body has a hollow back-post projecting from a surface thereof and an outer surface of said front body has a locking member projecting therefrom, and wherein the second end of said front body is disposed in the bore of said back body and the front body locking member are engageable to and the back body locking member secure together said front body and said back body;
- and
- a ferrule, having a bore therethrough, said ferrule disposed in the aperture of the first end of said front body with said buffer and said optical fiber disposed in the back-post and said optical fiber extending through the bore of said back post and into the bore of said ferrule.

A fiber optic connector comprising:
- a back body having a first opening and a second opening and a bore extending between the first and second openings;
- a front body having a first end, a second end, and a pair of shoulder regions, said front body further having a back post projecting from the second end thereof;
- a locking member disposed in the bore of said back body for engaging the pair of shoulder region in said front body;
- and
- a spring disposed over said back post, said spring for providing a force which maintains a contact region between the shoulder regions of said front body and the locking member disposed in the bore of said back body.
