Description

[Detailed description of the invention] The present invention relates to an installation structure for an optical adapter.

[Prior art]

When connecting optical fibers from the outside to the optical connection terminal section in an optical device, or when connecting optical fibers from the outside within the optical connection case,
A plurality of optical connector plugs are used, and a plurality of optical adapters corresponding to the optical connector plugs are arranged on the optical connection terminal portion or a plate in the housing.

However, if an optical connector plug that connects by screwing with a finger operation is employed, the optical adapter must be placed with a necessary distance from adjacent optical adapters to facilitate finger operation.

Therefore, in order to fix the arrangement of a large number of optical adapters, the plate becomes large, or multiple plates are required, resulting in restrictions on mounting electrical equipment in the optical equipment rack and an increase in the size of the optical connection housing. Problems such as these are occurring.

[Object of the Invention] An object of the present invention is to provide an optical adapter installation structure that allows a large number of optical adapters to be mounted in an optical connection terminal section or an optical connection housing within an optical device.

[Structure of the invention]

The optical adapter installation structure of the present invention is characterized in that a plurality of pairs of guide rails into which the flange portion of the optical adapter or the plate to which the optical adapter is attached are fitted and slidably guided are arranged in parallel in close proximity to each other in a plurality of planes. It is said that

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

In order to facilitate understanding of the embodiments of the present invention, a conventional optical adapter installation structure will first be described.

Figure 1 shows how optical connector plugs are connected to conventional optical adapters, where a plurality of optical adapters 2 are placed on a plate 1 with the necessary spacing so that the optical connector plugs 3 can be inserted and removed by rotating the fingers 4. It is located. Because the finger 4 is operated in this way, it is not possible to place adjacent optical adapters 2 in close contact with each other on the plate 1. was becoming larger.

FIG. 2 shows an embodiment according to the present invention, and FIG. 3 shows a cross section taken along line XX in FIG.

A rectangular hole 6 having a width slightly narrower than one side of the flange portion of the optical adapter 2 and having bent portions 5 on two short sides is formed in the plate 1'.
are arranged parallel to each other so that the long sides of the rectangles face in a certain direction. Also, a first plate fixed on the plate 1' and the long side of the rectangular hole
a guide member 7 and a second guide member 1 having a Z-shaped cross section.
3 form a grooved guide rail 8, and two sides of the flange of each optical connector adapter 2 are slidably placed between the grooves of the guide rail 8. The guide rails 8 are parallel to each other and have a length longer than one side of the flange of the optical adapter 2.

With the above structure, each optical adapter 2 can slide along the long side of the rectangular hole 6,
There is no need to maintain a spacing between the adapters in order to operate the fingers 4. Therefore, it is possible to arrange the guide rails extremely close to each other by considering only the size of the guide rails.

Note that the present invention is not limited to the above-mentioned embodiments. For example, in order to suppress the movement of the optical adapter due to vibration or earthquake after optical connection, the elastic adapter shown in FIG. Various fixing methods can be considered, such as attaching the plate 9 or attaching a fixing part 10 shown in FIG. 5 that fixes the two plates fitted into the guide rail with screws 10a.

Furthermore, in the embodiment, the flange portion of the optical adapter is slid within the guide rail, but the sixth embodiment
As shown in the figure, a slide plate 11 on which the optical adapter 2 is fixed individually may be used, and in the case of a guide rail, instead of a concave groove using the first and second guide members 7, 13, As shown in FIG. 7, attach the grooved plate 12 with the optical adapter 2 attached to the plate
It is also conceivable to use a convex guide rail that can be slid between the long sides of the rectangular hole. Further, in the embodiment, the plate is installed so as to slide horizontally, but it is also possible to install the plate vertically so that the optical adapter can move in the vertical direction.
As described above, the present invention can be implemented with various modifications.

〔Effect of the invention〕

As is clear from the above description, the optical adapter installation structure of the present invention can greatly alleviate the restriction on the number of optical adapters that can be installed due to restrictions on the optical adapter installation surface, and can also make the optical adapter installation plate larger. It is possible to avoid problems such as restrictions on mounting electrical equipment in an optical device or an increase in the size of an optical connection case caused by multilayering, that is, an enlargement of an optical adapter mounting area.
