Detailed ways

As shown in the perspective view of FIG. 1 and the exploded perspective view of FIG. 2 , the optical connector 100 according to the embodiment of the present invention includes a housing 10 , a ferrule 20 , a locking member 30 and an unlocking member 40 .

The optical connector 100 is used to install an optical fiber at the ferrule 20, for example, so that it is inserted into and fitted into the installation hole of an adapter or module on the opposite side and optically combined with the optical fiber on the opposite side. . However, the applicable field of the optical connector 100 is not limited to the coupling of optical fibers.

3 and 4 are cross-sectional views showing the configuration when the housing 10, the ferrule 20, the locking member 30, and the unlocking member 40 in the optical connector 100 are combined. FIG. 3 shows a state (locked state) when the optical connector 100 is mounted on an adapter, a module, or the like on the opposite side and locked. FIG. 4 shows a state in which the optical connector 100 is unlocked (unlocked state) when the optical connector 100 is detached from the adapter or module on the opposite side.

The housing 10 is provided with a receiving groove 11 which is drilled to the inside along the axis. In this embodiment, two ferrules 20 are provided. The ferrule 20 is provided on each of the left and right sides of the receiving groove 11 in parallel with the axis so as to protrude from the front end portion of the housing 10 .

The locking member 30 includes a first extending portion 31 , a second extending portion 32 , a rotating shaft 33 , a contact portion 34 and a latch 35 . The first extension portion 31 and the second extension portion 32 are connected to two sides of the rotating shaft 33 . That is, the 1st extension part 31 and the 2nd extension part 32 are connected so that it may be continuous, and the rotation shaft 33 is provided so that it may protrude toward both sides from the middle part. In addition, a groove having an abutting portion 34 inclined from the rotating shaft 33 toward the latch 35 is formed in the middle portion of the second extending portion 32 .

The locking member 30 is integrated into the housing 10 . Specifically, the locking member 30 is arranged in the accommodating groove 11 provided in the housing 10 . The locking member 30 is provided in the accommodating groove 11 of the housing 10 so as to be rotatable with the rotating shaft 33 as the central axis. That is, with the rotation shaft 33 as the central axis, when the first extension portion 31 is pushed down, the latch 35 is pushed up, and when the first extension portion 31 is pushed up, the latch 35 is pushed down.

The unlocking member 40 includes a handle portion 41 , a storage groove 42 , a position regulating portion 43 , and an operation protrusion portion 44 . The position regulating portion 43 is formed in a cylindrical shape so as to accommodate the housing 10 combined with the locking member 30 . In the present embodiment, since the outer shape of the casing 10 is formed in a rectangular shape, the position regulating portion 43 is formed in a rectangular cylindrical shape that fits into the casing 10 .

The handle portion 41 extends from the rear end portion of the position regulating portion 43 . The handle portion 41 functions as a portion for the user to operate when the optical connector 100 is attached to and detached from the adapter or module on the opposite side. By using the handle portion 41 to move the unlocking member 40 relative to the housing 10 , the locked state ( FIG. 3 ) in which the housing 10 is pushed into the unlocking member 40 and the unlocking state in which the housing 10 is pulled out by the unlocking member 40 can be selectively switched. state (Figure 4).

The inside of the handle portion 41 is formed as a hollow storage groove 42 . The hollow storage groove 42 is provided with an operation for abutting against the contact portion 34 of the locking member 30 when the housing 10 and the unlocking member 40 are slid and moved from the locked state ( FIG. 3 ) to the unlocked state ( FIG. 4 ). Protrusions 44 .

In a state where the unlocking member 40 is attached to the casing 10 in the direction indicated by the arrow in FIG. 2 , the operation protrusion 44 presses the latch in the process of moving the unlocking member 40 to the position where the locking state ( FIG. 3 ) is achieved. After the lock 35 is rotated clockwise by the latch 35 about the rotation shaft 33 and moved slightly downward, the operation protrusion 44 is accommodated in the abutting part 34 by the latch 35 . At the same time, the protruding portion 411 of the hollow storage groove 42 constituting the handle portion 41 presses the first extension portion 31, and the locking member 30 rotates counterclockwise about the rotation shaft 33 again, and becomes as shown in FIG. 3 . locked state.

That is, when the optical connector 100 is mounted on the adapter or module on the opposite side, the latch 35 can be locked on the card provided on the side of the adapter or module through the procedure shown above. The optical connector 100 is mounted on the adapter or the module while the stop portion is formed in a locked state ( FIG. 3 ).

On the other hand, when the unlocking member 40 is moved from the locked state ( FIG. 3 ) to the unlocked state ( FIG. 4 ), when the unlocking member 40 is pulled and moved toward the first extension portion 31 side (leftward in FIG. 3 ), The operation protrusion portion 44 abuts against the contact portion 34 of the lock member 30 , and rotates the lock member 30 in the clockwise direction about the rotation shaft 33 as an axis. At this time, since the protrusion portion 411 does not contact the first extension portion 31 due to the movement of the unlocking member 40 to the left, the locking member 30 can be rotated by the rotation shaft 33 as an axis. When the unlocking member 40 is further moved, the latch 35 is accommodated in the accommodating groove 11, the locked state is released, and the unlocked state is obtained ( FIG. 4 ). At this time, the first extension portion 31 is accommodated in the storage groove 42 of the unlocking member 40 .

In addition, when the locked state is released and the unlocked state is obtained, the unlocking member 40 is further pulled and moved (moved toward the left side in the drawing), whereby the optical connector 100 can be removed from the adapter or the module.

As described above, without elastically deforming the locking member 30 , the optical connector 100 can be formed in which the locked state and the unlocked state can be selectively shifted by rotating the latch 35 with the rotating shaft 33 as the rotating shaft.

However, the configuration of the optical connector 100 may be appropriately changed. For example, the arrangement of the abutting portion 34 in the lock member 30 and the operation protrusion portion 44 in the unlocking member 40 may be changed so that the first extension portion 31 can be moved from the lower side to the upper side in the unlocked state using the rotation shaft 33 as the rotation shaft. The contact part 34 and the operation protrusion part 44 are provided so that the locking member 30 is rotated by pushing. In addition, the arrangement of the first extension portion 31 in the locking member 30 and the protruding portion 411 in the unlocking member 40 may be changed, so that the second extension portion 32 can be moved from the lower side to the upper side in the locked state using the rotation shaft 33 as the rotation shaft. The first extending portion 31 and the protruding portion 411 are provided so as to rotate the locking member 30 by pushing. In addition, if the latch 35 is rotated with the rotating shaft 33 as the rotating shaft, the locked state and the unlocked state can be selectively shifted, and other structures can also be used.

In addition, for example, in the optical connector 100, two ferrules 20 are arranged to be configured, and the number and arrangement of the ferrules 20 may be changed. In addition, for example, in the optical connector 100, the receiving groove 11 and the locking member 30 are arranged between the two ferrules 20, but they may be arranged in the lateral direction of one ferrule 20, or may be arranged at other positions.

In addition, in the present embodiment, the optical connector 100 is formed as an optical fiber mounted on the ferrule 20, but the scope of application of the present invention is not limited to the optical fiber connector. For example, it may be formed as a connector in which electrical wiring is attached to the ferrule 20 .
