(Embodiment 1) FIGS. 1 to 3A and 6 show a first embodiment of a connector attaching / detaching tool according to the present invention.
It will be described in detail based on. As shown in FIG. 1, the tool has a MU shown in FIG. 6 (a) attached to the front ends of a pair of base materials 2 whose rear ends are connected to each other by a synthetic resin connecting member 10.
Locking hook 3 lockable / unlockable in locking hole N of connector C
A vibration preventing member 4 disposed outside the MU connector C held between the locking hooks 3 to prevent the connector 3 from vibrating.
Is provided.

As shown in FIG. 1, the base material 2 is a metal elongated plate material that becomes thinner in three stages from the rear end to the front end.
When the widest rear end side arbitrary portion (preferably approximately the center portion) is pinched and both base materials 2 are pressed inward in the opposite direction,
The front ends of the base materials 2 are closed close to each other, and when the pressing is released, the front ends of the respective base materials 2 are separated and opened by the self-elastic force.

As shown in FIG. 1, the locking hooks 3 are formed by bending the tips of the respective base materials 2 inwardly.
When the front end side of the base material 2 is closed as described above at the front end of the base material 2 and the front end side of the base material 2 is closed as described above, the MU connector C is fitted and locked in the locking hole N of the MU connector C disposed therebetween. The connector C is sandwiched and held therebetween (FIG. 3A), and when the front end side of the base material 2 is opened, the connector C is detached from the locking hole N to release the locking.

As shown in FIGS. 1 and 2, the anti-sway member 4 is formed by bending a thin metal plate having a thickness of 0.3 mm into a substantially U-shaped cross section. In the direction of the arrow ab in the figure, from a position at which the distal end surface R of the MU connector C can be surrounded (a position shown in FIG. 2) to a position at which the distal end surface R is exposed to the outside (a position shown in FIG. 1). It is possible to slide. The tip portion of each anti-vibration member 4 is enlarged in the direction facing each other as compared with the other portions, and as shown in FIG.
When the distal end face R of the U connector C is slid in the direction of the arrow b in the drawing to a position where the MU connector C can be surrounded, substantially the entire circumference of the MU connector C can be surrounded as shown in FIG. is there. As shown in FIGS. 1 and 2, an elongated hole 12 is opened on the back surface of each anti-vibration member 4, and a rivet 13 is attached to the base material 2 inside the elongate hole 12, so that the anti-vibration member 4 is provided. 4 is slid to a predetermined position in the direction of the arrow a or the direction of the arrow b in the figure, the rivet 13 comes into contact with the inner peripheral surface of the front end portion or the inner peripheral surface of the rear end portion of the elongated hole 12 so as not to slide further in the same direction. It is regulated. Further, a guide projection 14 that can be engaged with the guide groove L (FIG. 6B) of the adapter D is integrally provided at the tip of each shake prevention member 4. The function of the guide projection 14 is the same as that of the conventional connector attaching / detaching tool.

By using the optical connector attaching / detaching tool of the present invention shown in FIGS. 1 and 2, the insertion hole E of the adapter D shown in FIG.
In order to attach (insert) the MU connector C shown in FIG. (1) As shown in FIG. 1, in a state where the rear part of the MU connector C is arranged between the front ends of the opposing base materials 2 (between the locking hooks 3),
By closing the front end side of the base material 2, the locking hook 3 is fitted and locked in the locking hole N of the connector C, and the connector C is sandwiched and held between the locking hooks 3. (2) As shown in FIG.
In the direction to surround the distal end surface R of the MU connector C. This prevents the distal end surface R of the connector C from being scratched and dust from being attached, and also ensures that the longitudinal direction of the base material 2 matches the longitudinal direction of the MU connector C. The direction of C is regulated. More specifically, as shown in FIG. 3A, the anti-vibration member 4 comes into contact with the upper and lower surfaces of the optical connector C, and the arrow e of the connector C
Prevents swinging in the direction. (3) The guide projection 14 projecting from the tip of the shake preventing member 4 is engaged with the guide groove L corresponding to the predetermined insertion hole E of the adapter D shown in FIG. (4) The connector attaching / detaching tool (base material 2) is pressed toward the adapter D side. In this case, since the end face of the anti-vibration member 4 abuts against the peripheral edge of the insertion hole E of the adapter D and cannot be moved in the pressing direction, the base material 2 relatively moves in the same direction. The MU connector C held between the hooks 3 is pushed forward from the shake prevention member 4 and inserted into the insertion hole E.
At this time, since the longitudinal direction of the base material 2 and the longitudinal direction of the MU connector C coincide with each other, the engagement of the guide projection 14 and the guide groove L causes the longitudinal direction of the base material 2 and the axis of the insertion hole E to be aligned. By matching, the MU connector C is inserted straight into the insertion hole E. (5) When the MU connector C is inserted into the insertion hole E to a predetermined position, the base material 2 is opened to release the holding of the connector C, and then the connector attaching / detaching tool is pulled back.

The MU connector C mounted in the insertion hole E of the adapter D is detached (pulled out) therefrom by the optical connector attaching / detaching tool of the present invention shown in FIGS. 1 and 2 as shown in FIG. Is as follows. (1) As shown in FIG. 1, the anti-sway member 4 is slid in the direction of arrow a to expose the locking hook 3, and the locking hook 3 is attached to the MU connector C attached to the adapter D (FIG. 6b). To the outside of the locking hole N. (2) The front end side of the base material 2 is closed, and the locking hook 3 is fitted and locked in the locking hole N of the connector C.
Is held between the locking hooks 3. (3) The connector attaching / detaching tool (base material 2) is pulled toward the user, and the MU connector C is removed from the insertion hole E of the adapter D.

(Embodiment 2) A second embodiment of the connector attaching / detaching tool of the present invention will be described in detail with reference to FIG. The basic configuration of this tool is the same as that shown in FIGS. 1 to 3A. The difference is that, as shown in FIG. 4 (a), the operating portions 6 are provided at the rear ends of the pair of base materials 2 without connecting the rear ends of the base materials 2 to each other. When the side of the base member 2 is opened and the locking hook 3 locked in the locking hole N of the MU connector C is released, and the operation of the operation part 6 is released, the front end side of the base material 2 is automatically closed and locked. The hook 3 is locked in the locking hole N of the MU connector C.

More specifically, as shown in FIG. 4B, each base material 2 is provided on a support portion 22 protruding from the tip of the grip 20.
Are attached by a shaft 23 so as to be rotatable in the directions of arrows ab in the figure, and the bases 2 are connected to each other by a spring 5 at a position closer to the front end of the base 2 than the shaft 23, so that When the distal end sides of the base materials 2 are closed in the direction of arrow b by the elastic restoring force of the spring 5 and the operating unit 6 is closed in the direction of arrow c in the drawing against the elastic restoring force of the spring 5, the base material 2 Is opened in the direction of arrow a. Therefore, the MU connector C gripped by the connector attaching / detaching tool is gripped only by the elastic restoring force of the spring 5, and is always gripped with a uniform force, so that the connector C can be prevented from being damaged or deformed.

In the connector attaching / detaching tool of the present invention shown in FIG. 4, the base 2 has a U-shaped cross section, so that the locking projectingly provided at the tip of the base 2 as shown in FIG. When the optical connector C is held between the hooks 3, the inner peripheral surface 2
5 is arranged outside of the connector C (in contact with the outer peripheral surface of the connector C), and the direction of the connector C can be regulated so that the longitudinal direction of the base material 2 matches the longitudinal direction of the optical connector C. is there. Thereby, while maintaining the same effect as in the case where the anti-vibration member 4 is provided, the dimension (width W) near the front end of the base material 2 is reduced by the amount of the omission of the anti-vibration member 4,
Even if Adapter D is arranged at a narrow pitch,
The optical connector C can be detached.

(Embodiment 3) A third embodiment of the connector attaching / detaching tool according to the present invention will be described in detail with reference to FIG. The basic configuration of this tool is the same as that shown in FIGS. 1 to 3A. The difference is that the connector attaching / detaching tool shown in FIGS. 1 to 3A has two bases 2 joined by a joining member 10, but the tool shown in FIG. A pair of base materials 2 are formed by bending an elongated plate material at its center.
Is formed. Similar to the anti-vibration member 4, the connector C and the optical connector C are arranged near the front end of each of the substrates 2 shown in FIG. 5 so that the longitudinal direction of the optical connector C coincides with the longitudinal direction of the optical connector C.
Is provided. FIG.
Since the structure near the tip of the base member 2 is extremely simple, the dimensions of the vicinity of the tip of the base material 2 are much smaller than those of the connector removal tool shown in FIG. The optical connector C can also be attached and detached.

[0023]

The connector attaching / detaching tool of the present application has the following effects. (1) When the base material is closed, it is locked in the locking hole of the optical connector, and when the base material is opened, the locking hook is released so that the locking is released.
Unlike the conventional case, there is no need to operate the hook member specially, and it is not necessary to switch the operation between the insertion and removal of the optical connector. (2) Since an anti-vibration member is provided outside the optical connector to prevent the optical connector from oscillating, the optical connector can be inserted straight into the insertion hole of the adapter or pulled out straight from the insertion hole. . (3) The anti-vibration member can be slid to a position protruding from the front end surface of the optical connector, so that the optical connector can be fixed stably. Further, since the connector can be slid backward to a position where the distal end surface of the connector is exposed, the vibration preventing member does not interfere with the vicinity of the adapter. In addition, if the anti-vibration member of such a slide structure is configured to cover substantially the entire circumference of the optical connector, the distal end surface of the optical connector attached to the adapter is exposed to the outside once before and after the attachment. There is no.
Accordingly, there is no possibility that the cord or the like contacts the distal end surface of the optical connector during the mounting operation, and the distal end surface is damaged or dust adheres to the optical connector, thereby increasing insertion loss. (4) The locking hooks that oppose each other are biased by the spring in the direction in which the locking hooks approach each other, and the locking hooks are locked in the locking holes of the optical connector. Is opened when it is opened against the urging of the spring, there is no danger that the locking hook will be released accidentally during operation and the optical connector will fall. Further, since the optical connector is always held at a constant pressing force, there is no possibility that an unnecessary force acts on the optical connector to damage the optical connector. (5) Since the pair of base materials are formed by bending an elongated plate material, the structure is extremely simple, the production is easy, and the cost is low. (6) The optical connector can be attached to and detached from adapters arranged at a narrow pitch.
