Optical connector and insertion and removal method of optical connector

1. An optical connector insertable into and removable from an optical connector adapter, the optical connector comprising: a housing which houses a ferrule; a coupling attached to the housing by inserting the housing into the coupling; a coupling engagement member attached to a rear of the housing by inserting the housing into the coupling engagement member, the coupling engagement member being movable in a forward direction and a rearward direction with respect to the housing and the coupling engagement member being connected to the coupling; and a boot formed to accommodate an optical fiber therethrough and attached to the coupling engagement member so as to extend rearward from the coupling engagement member, wherein the coupling engagement member can exert a forward pressure on the housing by pressing the boot in the forward direction, thereby a latch of the optical connector adapter can be attached to the housing, wherein the coupling engagement member can exert a rearward pressure on the coupling by pulling the boot in the rearward direction thereby the latch of the optical connector adapter can be detached from the housing, wherein the boot is attached to the coupling engagement member via a connection member formed in a tubular shape, and wherein the connection member comprises a fitting convex portion, and the coupling engagement comprises a fitting opening and the connection member is attached to the coupling engagement member when the fitting convex portion fits into the fitting opening.

2. The optical connector according to claim 1 ,

wherein the coupling engagement member comprises a main body and a pair of extending portions extending forward from the main body,

wherein the pair of extending portions connect the coupling engagement member with the coupling.

3. The optical connector according to claim 1 ,

wherein an engagement concave portion is provided on one of the coupling and the coupling engagement member, and an engagement convex portion is engageable with the engagement concave portion and is provided on the other of the coupling and the coupling engagement member,

a length of the engagement concave portion in a front-back direction is greater than a length of the engagement convex portion in a forward-backward direction, such that the engagement convex portion is moveable within the engagement concave portion.

4. The optical connector according to claim 1 ,

wherein an operation portion is formed at a rear portion of the boot and extends outward from the rear portion of the boot.

5. An optical connector insertable into and removable from an optical connector adapter, the optical connector comprising: a housing which houses a ferrule; a coupling attached to the housing by inserting the housing into the coupling; a coupling engagement member attached to a rear of the housing by inserting the housing into the coupling engagement member, the coupling engagement member being movable in a forward direction and a rearward direction with respect to the housing and the coupling engagement member being connected to the coupling; and a boot comprising an opening formed to accommodate an optical fiber therethrough and attached to the coupling engagement member so as to extend rearward from the coupling engagement member, wherein the boot comprises a body which is substantially radially symmetric with respect to a central axis and operation portion which extends outward from the rear of the body, wherein the coupling engagement member can exert a forward pressure on the housing by pressing the boot in the forward direction, thereby a latch of the optical connector adapter can be attached to the optical connector, wherein the coupling engagement member can exert a rearward pressure on the coupling by pulling the boot in the rearward direction thereby the latch of the optical connector adapter can be detached from the housing wherein the boot is attached to the coupling engagement member via a connection member formed in a tubular shape, and wherein the connection member comprises a fitting convex portion, and the coupling engagement member comprises a fitting opening and the connection member is attached to the coupling engagement member when the fitting convex portion fits into the fitting opening.

6. An optical connector insertable into and removable from an optical connector adapter, the optical connector comprising:

a housing which houses a ferrule;

a coupling attached to the housing by being inserted into the coupling;

a coupling engagement member attached to a rear of the housing by being inserted into the housing, the coupling engagement member being movable in a forward direction and a rearward direction with respect to the housing and the coupling engagement member being connected to the coupling; and

a boot comprising an opening formed to accommodate an optical fiber therethrough and attached to the coupling engagement member so as to extend rearward from the coupling engagement member,

wherein the boot comprises a body which is substantially radially symmetric with respect to a central axis and an operation portion which extends outward from the rear of the body,

wherein the coupling engagement member can exert a forward pressure on the housing by pressing the boot in the forward direction, thereby a latch of the optical connector adapter can be attached to the optical connector; and

wherein the coupling engagement member can exert a rearward pressure on the coupling by pulling the boot in the rearward direction thereby

the latch of the optical connector adapter can be detached from the housing.
