Optical connector
An optical connector includes an optical fiber, a ferrule provided at an end portion of the optical fiber, a plug housing in which the ferrule is accommodated, a lock arm provided on the plug housing and holding the plug housing and the mating housing in a fitted state, a holder assembled to the plug housing to hold the ferrule in the plug housing, and a holder protrusion provided on the holder and pressed by the lock arm which is flexibly deformed in an unlocking direction by a predetermined amount or more so that the holder is displaced in a direction of releasing the ferrule from being held by the holder.
1. An optical connector comprising:
an optical fiber;
a ferrule provided at an end portion of the optical fiber;
a housing in which the ferrule is accommodated;
a lock arm that is provided on the housing and is flexibly deformed when being fitted with a mating housing and restores after the fitting to lock the mating housing so that the housing and the mating housing are held in a fitted state;
a holder assembled to the housing to hold the ferrule in the housing; and
a holder protrusion that is provided on the holder and is pressed by the lock arm which is flexibly deformed in an unlocking direction by a predetermined amount or more so that the holder is displaced in a direction of releasing the ferrule from being held by the holder, and
wherein the holder is locked to a locked portion of the housing by a lock portion, the lock portion including a temporary lock portion that holds the holder to the housing to allow the ferrule to be inserted into the housing, and a main lock portion that holds the holder by inserting the holder into the housing in a state in which the ferrule is accommodated in the housing.
2. The optical connector according to claim 1 ,
wherein a lock surface of the main lock portion is an inclined surface that causes the lock portion to flexibly deform in the unlocking direction by coming into sliding contact with a lock surface of the locked portion.
3. The optical connector according to claim 1 ,
wherein the holder protrusion is provided in a middle position between a pair of the lock portions extending on both sides of the holder in an attaching direction in which the holder is attached to the housing.
