BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attaching / detaching tool for facilitating an attaching / detaching operation of an optical connector.

[0002]

2. Description of the Related Art As an example of a conventional optical connector that enables particularly high-density mounting, for example, as described in Reference 3 of JIS C 5973, four F04 type single-core optical fiber connectors are used. In some cases, multi-core connection is made using a batch adapter. In this case, when the plug is inserted into and removed from the adapter, for example, a detachable tool having a structure as shown in FIG. 5 is used. When the plug is inserted into the quadruple adapter, the plug is held by the attaching / detaching tool, and the plug is connected to the adapter by pushing the plug into a target port of the adapter. Also, when removing the plug, the removal tool is inserted by inserting the removal tool along the target plug, operating the lever 41 to couple the tool to the plug, and then pulling out the removal tool.

Here, as another example of an optical connector that enables high-density mounting, there is an optical connector as described in Japanese Patent Application No. 1-310680. Since this optical connector plug employs a push-pull coupling system, it can be coupled to and released from the optical connector housing only by operating the plug in the axial direction. However,
Since optical connector plugs are densely mounted on the back panel, it is very difficult to operate individual plugs by hand. In addition, when used as a plug-in optical connector, usually, other electrical cables, cable catches, etc. are densely packed behind the back panel, and the optical connector itself is located deeper than these cables. ing.

[0004]

When a conventional detachable tool as shown in FIG. 5 is used on a back panel where cables and the like are densely arranged as described above, the tool is accurately inserted in a target port. It is very difficult. Further, there is a problem that it is very difficult to operate the lever or the like of the tool in a state where the cables and the like are densely packed.

An object of the present invention is to provide an optical connector attaching / detaching tool capable of easily performing an attaching / detaching operation even in a state where optical connector plugs are densely mounted and cables and the like are congested. is there.

[0006]

According to the present invention, there is provided an optical connector housing comprising: an optical connector housing;
Through the plurality of optical connector plugs
Notches and each housed optical connector plug
A guide groove that is provided along and guides the insertion jig and extraction jig.
U-shaped guide jig with optical connector plug
Temporarily, and push it in as it is pushed into the guide groove.
Opened and held in cooperation with the lever to be moved
With a hook at the tip to release the optical connector plug
Insert the jig into the guide groove, hook it into the hole
Removal with hook at the tip to pull out optical connector plug
And a jig.

[0007]

According to the above construction, even when the optical connector plugs are densely mounted and the cables are congested, the insertion jig or the removal jig is operated after the guide jig is attached. This makes it possible to easily perform the intended operation of inserting and removing the optical connector plug.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a view for explaining an embodiment of a guide jig in a detachable tool according to the present invention, wherein FIG. 1 (a) is a left side view, FIG. 1 (b) is a front view, and FIG. FIG. 2D is a sectional view taken along the line II of FIG.

One of the guide jigs 1 having a rectangular shape in a front view.
A notch 2 is provided on the side (short side), and the whole has a U-shape. Therefore, a large number of optical connector plugs 31 are provided in an optical connector housing 30 (see FIG. 4) described later.
Even when the optical connector plugs 31 are connected to each other (see FIG. 4), the guide jig 1
Can be attached to the optical connector housing 30. In the drawing, reference numeral 3 denotes a dowel which fits into a dowel hole (not shown) on the optical connector housing 30 side, and 4 denotes a pair of guide grooves formed at eight locations in the long side direction.

FIG. 2 is a view for explaining an embodiment of the insertion jig in the detachable tool according to the present invention, wherein FIG. 2A is a plan view, FIG. 2B is a side view, and FIG. Is a front view.

A pair of hooks 12 projecting forward of the main body 10 are opened by operating levers 11 provided on both sides of the main body 10a of the insertion jig 10, and an optical connector plug 31 is coupled thereto. Then, in this state, the guide jig 1 is inserted along the guide groove 4. Guide groove 4
Is set smaller than the width of the lever 11,
As the insertion jig 10 is pushed in, the lever 11 is pushed,
The hook 12 opens. At this time, since the optical connector plug 31 is already held in the guide jig 1, the optical connector plug 3
1 will be inserted into the optical connector housing 30. When the insertion jig 10 is pulled out after the optical connector plug 31 is completely connected, only the insertion jig 10 is pulled out because the hook 12 is already open. In the illustrated example, the lever 11 and the hook 12 are integrally formed using an elastic member. 10b is a handle.

FIG. 3 is a view for explaining an embodiment of a removal jig in the detachable tool according to the present invention. FIG. 3A is a plan view, FIG. 3B is a side view, and FIG. Is a front view.

A pair of elastic member hooks 22 project from the front of the main body 20a of the extraction jig 20. When the removal jig 20 is inserted into the guide jig 1, the hook 22 is caught by the hole 32 (see FIG. 4) at the rear end of the optical connector plug 31, and then the removal jig 20 is pulled out.
The optical connector plug 31 is pulled out together with the removal jig 20. In the figure, reference numeral 20b denotes a handle.

FIG. 4 shows the positional relationship between the optical connector housing 30, the optical connector plug 31, the guide jig 1 and the insertion jig 10 of the present invention, which are described in Japanese Patent Application No. 1-310680. FIG. A hole 32 is provided at the rear end of the optical connector plug 31, and the hole 32 is connected to the hook 12 of the insertion jig 10 or the hook 22 of the removal jig 20.

[0015]

As described above, in the optical connector attaching / detaching tool according to the present invention, the guide jig is attached to the optical connector housing, and then the insertion jig or the removal jig is inserted along the guide jig. Therefore, it is possible to very easily operate the attachment / detachment tool with respect to the target optical connector plug. In addition, the optical connector plug and the insertion / removal jig are automatically connected or disconnected only by the operation of inserting the insertion jig or the removal jig into the guide jig. Operation becomes much easier. These features have a particularly remarkable effect in facilitating the attachment / detachment operation in a state where the optical connector plugs are densely mounted and the cables and the like are congested.
