DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a panel mounting bracket for an optical adapter.

[0002]

2. Description of the Related Art Conventional optical adapter panel mounting brackets are:
As shown in FIGS. 7 to 10, the front plates c and d are provided with a protruding piece e for pressing and supporting one side h of the panel g and a spring piece f for pressing and supporting the other side i of the panel g. A pair of U-shaped metal fittings a and b that are fitted and fixed from both upper and lower surfaces of the optical adapter K are formed on the left and right side plates 1 and m of the metal fittings a and b.
In n and o, fitting holes r and s for fitting with engaging projections p and q protruding from both left and right side surfaces of the optical adapter K are formed to face each other.

As shown in FIG. 9 (A), an optical adapter has a pair of metal fittings a and b with one side plates l and o inside and the other side plates m and n outside. By opposing pressing from both upper and lower sides of K, each side plate l, m, n, o rides on the engaging projections p, q and is pushed outwards against its own elasticity, Furthermore, a pair of fittings a and b
When the is pressed, the fitting holes r and u of the side plates 1 and o and the fitting holes s and t of the side plates m and n are fitted to the engaging projections p and q, respectively, as shown in FIG. As described above, it is fixed to the optical adapter K.

[0004]

However, according to the conventional panel mounting bracket described above, when a pair presses and fixes the brackets a and b from both the upper and lower sides of the optical adapter K,
Each side plate l, m, n, o must be pushed outward at the same time. At this time, especially the inner side plate l, o has the outer side plate m, n in addition to its own elasticity. The outer side plates m, n must be spread out against the resilience.
However, there are various problems such as difficulty in expanding the side plates 1 and o, fitting and fixing to the optical adapter K is complicated and time-consuming, and the working efficiency of the fitting and fixing is extremely low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the above-mentioned conventional optical adapter panel mounting bracket.
Each one side plate is provided with a fitting hole for fitting with the engaging protrusion of the optical adapter, and the other side plate is provided with an engaging recess for engaging with the engaging protrusion at a lower end of the side plate. When the pair of metal fittings is fitted from both the upper and lower sides of the optical adapter with the side plate provided with the engaging recess inside and the side plate provided with the fitting hole outside, the fitting recess is provided. The inner side plate is not expanded, and only the outer side plate is expanded, so that it can be easily and quickly fitted and fixed to the optical adapter. It is an object of the present invention to provide a panel mounting bracket for an optical adapter which can be significantly improved.

According to the present invention, in order to achieve the above object, a front plate is provided with a projecting piece and a spring piece for pressing and supporting a panel from both sides, and a pair of U-shaped fittings are fitted and fixed from both upper and lower sides of an optical adapter. A panel mounting bracket having a shape, wherein one of two side plates that are fitted and fixed to each other on the right and left side surfaces of the optical adapter is fitted into an engagement protrusion on a side surface of the optical adapter. The hole is formed on the other side plate, and an engagement recess for engaging with the engagement protrusion is formed at each end of the side plate.

[0007]

When fitting a pair of metal fittings from the upper and lower sides of the optical adapter, one side plate provided with the engaging concave portions of the two metal fittings is set to the inside (the side of the optical adapter) and a fitting hole is provided. When the other side plate is pressed against the upper and lower sides of the optical adapter as the outer side, the one side plate slides along both side surfaces of the optical adapter without being expanded outward. The engagement recesses engage with both engagement protrusions on the side surface of the optical adapter.

At this time, the other side plate is spread outwardly by riding on the engaging projection. Further, by pressing both metal fittings oppositely, the above-mentioned engaging concave portion is engaged with the above-mentioned engaging protrusion to a predetermined position, and at the same time, the fitting hole of the other side plate is opposed to the above-mentioned engaging protrusion. Then, the other side plate returns to the original position (vertical) by the restoring force,
An engagement hole is fitted to the engagement protrusion, and a pair of metal fittings is fitted and fixed to the optical adapter.
