Description

Connector

The present invention relates to a connector that can be easily locked and released with an adapter or a module.

When connecting an optical fiber to an adapter or module, use a connector that can lock and release the connection state. For example, a housing is disclosed that includes a lock lever, the lock lever is provided with a locked portion that is locked in a fitted state with an opposite side, and a connector formed by combining the housing and a sliding cover that can slide on the housing. The sliding cover is slidable on the housing and has an operating part extending in the detaching direction. If the operating part is operated in the detaching direction, the abutting part contacts the operated part of the lock lever to elastically deform the operated part to unlock the lock (Patent Document 1). [Prior technical literature] [Patent Literature]

[Patent Document 1] JP 2005-173173 A.

[Problems to be solved by the invention]

However, in the conventional technology, since the elastic deformation of the operated portion of the lock lever is used, when the locking and unlocking of the connector are repeated, plastic deformation gradually occurs, and the locking or unlocking may not be performed reliably. [Means to solve the problem]

One aspect of the present invention is a connector, including a housing, a locking member, and an unlocking member. The locking member has a first extension, a second extension, and a rotating shaft. The second extension is provided with other components. For the latched latch, the first extension part and the second extension part are connected by a rotating shaft, and are installed on the housing with the rotating shaft as the center of rotation. The unlocking member is configured to be relatively movable to the housing, by unlocking The member moves relative to the housing, and rotates the first extension portion and the aforementioned second extension portion with the rotation axis as the rotation center, thereby moving the latch to selectively switch the locked state and the unlocked state.

Here, it is preferable that the unlocking member has a handle portion, a storage groove, a position regulating portion, and an operating protrusion. The position regulating portion is formed into a shape that can be attached to the housing, and the handle portion faces the side of the position regulating portion inserted into the housing. The opposite side of the lock member extends and protrudes, and the storage groove is provided in the handle portion. By relatively moving the unlocking member toward the side opposite to the side inserted into the housing, the operating protrusion abuts against the abutment portion of the lock member and rotates the shaft The locking member is rotated for the center of rotation, and the latch shifts from the locked state to the unlocked state. [Effects of Invention]

With the present invention, it is possible to provide a connector that can be locked and unlocked without using the elastic deformation of the member.

As shown in the perspective view of FIG. 1 and the exploded perspective view of FIG. 2, the optical connector 100 in the embodiment of the present invention is configured to include 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, for example, the ferrule 20, so that it is inserted into and fitted into the mounting hole of the adapter or module on the opposite side to form an optical type with the optical fiber on the opposite side. Combine. However, the application field of the optical connector 100 is not limited to the combination of optical fibers.

In addition, FIGS. 3 and 4 are cross-sectional views showing the structure 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 installed on the adapter or module on the opposite side and locked. FIG. 4 shows the unlocked state (unlocked state) when the optical connector 100 is removed from the adapter or module on the opposite side.

The housing 10 is provided with a receiving groove 11 penetrated 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 accommodating groove 11 so as to protrude from the front end of the housing 10 in parallel with the axis.

The locking member 30 includes a first extension portion 31, a second extension 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 both sides of the rotating shaft 33. That is, the first extension portion 31 and the second extension portion 32 are connected in a continuous manner, and the rotating shaft 33 is provided so as to protrude from the middle portion 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 extension portion 32.

The locking member 30 is incorporated in the housing 10. Specifically, the locking member 30 is arranged in the receiving groove 11 provided in the housing 10. The locking member 30 is arranged in the receiving groove 11 of the housing 10 so as to be rotatable with the rotating shaft 33 as the central axis. That is, with the rotating shaft 33 as the central axis, when the first extension portion 31 is pressed, the latch 35 is pushed up, and when the first extension portion 31 is pushed up, the latch 35 is pressed 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, 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 cylindrical shape fitted to the housing 10.

The handle portion 41 is extended from the rear end of the position regulating portion 43. The handle 41 functions as a part for the user to operate when the optical connector 100 is installed and removed as an opposing adapter or module. The handle 41 is used to move the unlocking member 40 relative to the housing 10, thereby selectively switching between pushing the housing 10 into the locked state of the unlocking member 40 (FIG. 3) and unlocking the housing 10 when the unlocking member 40 is pulled out Status (Figure 4).

The inside of the handle portion 41 is formed as a hollow storage groove 42. In the hollow storage groove 42, there is provided an operation for contacting the abutting portion 34 of the locking member 30 when the housing 10 and the unlocking member 40 slide to move from the locked state (FIG. 3) to the unlocked state (FIG. 4) Protruding part 44.

In the state in which the unlocking member 40 is installed in the housing 10 in the direction indicated by the arrow in FIG. 2 and the unlocking member 40 is moved to the position in the locked state (FIG. 3), the operating projection 44 presses the latch After the lock 35 is rotated in the clockwise direction with the rotation shaft 33 as an axis and moved slightly downward by the latch 35, the operating protrusion 44 is accommodated in the contact portion 34 by the latch 35. At the same time, the protrusion 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 around the rotation shaft 33 again to become as shown in FIG. 3 Locked state.

That is, when the optical connector 100 is installed on the adapter or the module on the opposite side, the latch 35 can be locked on the side of the adapter or the module by the sequence shown above. The locking portion is formed into a locked state (Figure 3), and the optical connector 100 is mounted on the adapter or module.

On the other hand, when the unlocking member 40 is moved from the locked state (FIG. 3) to the unlocked state (FIG. 4), if the unlocking member 40 is stretched and moved toward the first extension portion 31 side (the left direction in FIG. 3), The operating protrusion 44 abuts on the abutting portion 34 of the lock member 30 and rotates the lock member 30 in a clockwise direction with the rotation shaft 33 as an axis. At this time, due to the relationship of the unlocking member 40 moving to the left, the protrusion 411 does not abut the first extension portion 31, and therefore the rotation shaft 33 can be used as a shaft to rotate the locking member 30. If the unlocking member 40 continues to move, the latch 35 is accommodated in the accommodating groove 11, the locked state is released, and it becomes an unlocked state (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 becomes the unlocked state, the unlocking member 40 is further stretched and moved (moved to the left in the drawing), whereby the optical connector 100 can be detached from the adapter or module.

As described above, it is possible to form the optical connector 100 that does not need to elastically deform the locking member 30, and rotates the latch 35 with the rotating shaft 33 as the rotating shaft, whereby the locked state and the unlocked state can be selectively shifted.

However, the structure of the optical connector 100 may be appropriately changed. For example, it is also possible to change the arrangement of the abutment portion 34 in the locking member 30 and the operating protrusion 44 in the unlocking member 40, so that the rotation shaft 33 is used as a rotation axis and the first extension portion 31 is moved from the lower side in the unlocked state. The locking member 30 is pushed to rotate, and the abutting portion 34 and the operating protrusion 44 are provided. In addition, the arrangement of the first extension portion 31 of the locking member 30 and the protrusion portion 411 of the unlocking member 40 can also be changed so that the rotation shaft 33 is used as a rotation axis and the second extension portion 32 is moved from the lower side in the locked state. The locking member 30 is pushed to rotate, and the first extension portion 31 and the protrusion portion 411 are provided. 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 may be adopted.

In addition, for example, in the optical connector 100, the ferrule 20 is configured by two arrangements, and the number of the ferrule 20 can be changed, and the arrangement can also be changed. In addition, for example, in the optical connector 100, the accommodating 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 in other positions.

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