Optical connector

An optical connector comprising:

• a ferrule to which one end of an optical fiber cable is fixed;
• a housing having a front end and a rear end, a locking hole being provided at each of two opposite sides of the front end, wherein a head is defined at the front end, the ferrule is housed in the head and a at least a portion of an other end of the optical fiber cable extends from the rear end;
• a coupling which is externally fitted to the housing, the coupling being slidable in a longitudinal direction of the housing and biased toward the front end;
• a spring push which is internally inserted into the rear end of the housing, the spring push being provided at a front end with a locking projection to be locked into one of the locking holes at the front of the housing;
• a protective boot which extends from the rear end of the housing, with a leading end thereof engaged with the spring push, at least a portion of the protective boot partly surrounding at least a portion of the other end of the optical fiber cable;
• the coupling and the spring push being configured to lock the spring push to an elastic locking portion within an adapter by advancing the coupling;
• and
• the coupling and the spring push being configured to unlock the spring push from the elastic locking portion within the adapter to allow the spring push to be pulled out from the housing by retreating the coupling,
• wherein at least a pair of locking holes and locking projections are respectively provided behind the locking hole at the front of the housing and the locking projection at the front of the spring push, and
• wherein a load applied to the locking projection at the head of the spring push is distributed with the aid of the locking projection at the rear thereof when the optical fiber cable is bent.
