Detailed Description

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

The optical connector 100 is used to mount an optical fiber on, for example, a ferrule 20, and to insert and fit the optical fiber into a mounting hole of an adapter or a module on the opposite side to optically couple the optical fiber on the opposite side. However, the application field of the optical connector 100 is not limited to the coupling of optical fibers.

Fig. 3 and 4 are cross-sectional views showing a structure in which the housing 10, the ferrule 20, the locking member 30, and the unlocking member 40 are combined in the optical connector 100. 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 (unlocked state) in which the optical connector 100 is unlocked when it is removed from the adapter or module on the opposite side.

The housing 10 has a housing groove 11 formed therein along the axis. In this embodiment, 2 ferrules 20 are provided. The ferrule 20 is provided on each of the left and right sides of the housing groove 11 so as to protrude from the front end of the housing 10 in parallel with the axial center.

The locking member 30 includes a first extension 31, a second extension 32, a rotation shaft 33, an abutting portion 34 and a latch 35. The first extension 31 and the second extension 32 are connected to both sides of the rotation shaft 33. That is, the first extension 31 and the second extension 32 are continuously connected, and the rotation shaft 33 is provided so as to protrude from the middle portion thereof to both sides. In addition, a groove having an abutting portion 34 inclined from the rotation shaft 33 toward the latch 35 is provided in the middle portion of the second extending portion 32.

The locking member 30 is incorporated in the housing 10. Specifically, the lock member 30 is disposed in the housing groove 11 of the housing 10. The locking member 30 is rotatably provided in the housing groove 11 of the housing 10 about the rotation shaft 33. That is, when the first extension 31 is pushed down with the rotation shaft 33 as a center axis, the latch 35 is pushed up, and when the first extension 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 regulation portion 43, and an operation protrusion portion 44. The position regulation part 43 is formed in a cylindrical shape so as to house the housing 10 combined with the lock member 30. In the present embodiment, the outer shape of the housing 10 is formed in a rectangular shape, and therefore the position regulating portion 43 is formed in a rectangular tubular shape fitted to the housing 10.

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

The handle portion 41 is formed with a hollow storage groove 42 therein. The hollow storage groove 42 is provided with an operation protrusion 44 which comes into contact with the contact portion 34 of the lock member 30 when the housing 10 and the unlock member 40 are slid and shifted from the locked state (fig. 3) to the unlocked state (fig. 4).

In a state where the unlocking member 40 is attached to the housing 10 in the direction of the arrow in fig. 2, the operation protrusion 44 presses the latch 35 in a process of moving the unlocking member 40 to a position where the unlocking member is in the locked state (fig. 3), and after the operation protrusion 44 is slightly moved downward by the latch 35 being rotated clockwise about the rotation shaft 33, the operation protrusion 44 is accommodated in the abutting portion 34 by the latch 35. At the same time, the protrusion 411 constituting the hollow storage groove 42 of the handle portion 41 presses the first extending portion 31, and the locking member 30 is again rotated counterclockwise about the rotation shaft 33 as an axis, and becomes the locked state shown in fig. 3.

That is, when the optical connector 100 is mounted on the adapter or the module on the opposite side, the latch 35 is locked to the locking portion provided on the side of the adapter or the module in the above-described procedure, and the optical connector 100 can be mounted on the adapter or the module in the locked state (fig. 3).

On the other hand, when the unlocking member 40 is moved by being pulled toward the first extending portion 31 (in the left direction in fig. 3) when the unlocking member 40 is shifted from the locked state (fig. 3) to the unlocked state (fig. 4), the operation protrusion 44 comes into contact with the contact portion 34 of the locking member 30, and the locking member 30 is rotated clockwise about the rotation shaft 33. At this time, the protrusion 411 does not abut on the first extending portion 31 due to the leftward movement of the unlocking member 40, and therefore the locking member 30 can be rotated about the rotation shaft 33. When the unlocking member 40 is further moved, the latch 35 is accommodated in the accommodating groove 11, and the locked state is released to become the unlocked state (fig. 4). At this time, the first extension 31 is received in the storage groove 42 of the unlocking member 40.

When the locked state is released and the unlocked state is reached, the unlocking member 40 is further pulled and moved (moved to the left side in the drawing), and the optical connector 100 can be removed from the adapter or the module.

As described above, the optical connector 100 can be formed in which the latch 35 is rotated about the rotation shaft 33 as a rotation shaft without elastically deforming the lock member 30, and the locked state and the unlocked state can be selectively shifted.

The configuration of the optical connector 100 may be changed as appropriate. For example, the arrangement of the abutting portion 34 of the lock member 30 and the operation protrusion 44 of the unlock member 40 may be changed such that the abutting portion 34 and the operation protrusion 44 are provided so that the rotation shaft 33 is used as a rotation shaft, and the first extending portion 31 is pushed up from the lower side in the unlocked state to rotate the lock member 30. In addition, the arrangement of the first extending portion 31 of the lock member 30 and the protrusion 411 of the unlock member 40 may be changed such that the first extending portion 31 and the protrusion 411 are provided so that the second extending portion 32 is pushed up from the lower side in the locked state with the rotation shaft 33 as the rotation shaft to rotate the lock member 30. Further, if the latch 35 is rotated about the rotation shaft 33, the locked state and the unlocked state can be selectively shifted, and other configurations may be adopted.

For example, in the optical connector 100, the arrangement of two ferrules 20 may be provided, and the number of ferrules 20 may be changed or the arrangement may be changed. For example, in the optical connector 100, the housing groove 11 and the lock member 30 are disposed between 2 ferrules 20, but may be disposed in the lateral direction of one ferrule 20 or may be disposed at other positions.

In the present embodiment, the optical connector 100 is formed by mounting an optical fiber on the ferrule 20, but the application range of the present invention is not limited to the connector for an optical fiber. For example, a connector in which electrical wiring is mounted on the ferrule 20 may be used.
