[0010]

In this conventional panel mounting structure, since the mounting structure uses guide rails on the upper and lower sides of the panel, this mounting structure of a plug-in type is used in a housing having a narrow opening. Then, a guide rail for guiding the top and bottom of the panel is required. in this way,
Mounting two upper and lower guide rails in the housing
There has been a problem in that the workability and the man-hour for mounting the guide rail are disadvantageous.

When it is necessary to connect cables from the outside to the panel inside the housing, especially when outdoors, etc., the introduction of cables from the lower part of the housing becomes mainstream because of the waterproof structure of the housing. Although it is necessary to secure a lower space and an introduction path to the panel, there is a problem that the guide rail for guiding the lower side of the panel becomes a hindrance when cables are drawn into the panel from outside the housing.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a panel mounting structure for a communication device in which the mounting structure of the panel in a narrow place where mounting becomes difficult is reduced in size and weight to improve productivity and maintainability. To provide.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a panel mounting structure according to the present invention, wherein (a) and (b) show states before and after mounting the panel on a housing, respectively.

FIGS. 2A and 2B are an exploded perspective view of the panel and a housing of FIG. 1, respectively.

Further, FIGS. 3 (a), 3 (b) and 3 (c)
3A and 3B are a side view and a front view, respectively, showing a relative position between the panel and the guide fitting in a process until the panel in FIG. 1 is mounted by being guided by the guide fitting.

In the present embodiment, as shown in FIG. 1A, the panel 1 is inserted into the housing 8 in the direction indicated by the dashed arrow, and is slid in the rear direction of the housing 8, to thereby obtain the structure shown in FIG.
The state shown in FIG.

As shown in FIG. 2A, the panel 1 has a structure in which a substrate 2 provided with a connector 4 for connection to the main body is screwed to the panel mounting member 3 by screws 30a.

The panel mounting member 3 has a substantially L-shape, and one side 3
a is bent to form the strip pieces 3b, 3c, 3d, and the bent end 3e is bent at 90 ° in the opposite direction to the other side to form a mounting hole, so that a substantially L-shaped panel mounting is provided. Mounting holes for mounting the substrate 2 with screws 30a are provided on the side planes 3f and 3g of the fixture 3.

As shown by a chain line arrow in FIG. 2B, the guide fitting 6 screwed into the main body case 7 with the screw 30b is formed by processing a thin sheet metal.
One end of a sheet metal flat plate 6a having a hole 6b drawn in a T-shape for holding the connector 5 and the panel 1 for making a connection with the panel 1 and sliding the panel 1 is connected to a portion of the hole 6b above the neck of the T-shape. The other end of the sheet metal flat plate 6a is bent in the opposite direction to the above-mentioned one end to form a Z-shape, and the other end of the sheet metal plate 6a is formed into a Z-shape so as to form the opening 6c. Are provided with mounting holes for mounting to the main body case 7.

Further, the main body case 7 is integrally formed with a boss, a mounting portion of the connector 5 and the like which engage with a mounting screw hole on the front side and a mounting hole of the guide fitting 6 on the rear side provided by die casting or the like. I have.

Next, the assembly of this embodiment will be described with reference to FIGS.

As shown by a chain line arrow in FIG. 2B, a mounting hole provided on the back side of the guide fitting 6 is engaged with a boss integrally formed on the back side of the main body case 7.

Thereafter, the mounting hole of the guide fitting 6 is aligned with the mounting screw hole on the front side of the main body case 7, and screwed by the screw 30b.

Next, as shown by a chain line arrow in FIG. 2B, the connector 5 is screwed to a connector mounting portion formed integrally with the main body case 7 with a screw 30c.

On the other hand, as shown by a chain line arrow in FIG. 1, the panel 1 is inserted from the front of the housing 8 by bending one side of the panel mounting fixture 3 to the opening 6 c of the guide fitting 6. Slide toward the back.

At this time, the T-shaped hole 6 on the guide fitting 6
b (shown in FIG. 2 (b)) serves as a guide to guide the panel 1, and from the state shown in FIG. 3 (b) to FIG.
In the state shown in (c), the connector 5 on the housing 8 and the connector 4 on the panel 1 are fitted.

Then, the mounting of the panel 1 on the housing 8 is completed by fixing the mounting holes of the guide fitting 6 and the mounting screw holes of the housing 8 with screws, and the state shown in FIG. 1B is obtained.

[0032]

As described above, the present invention comprises the panel guide means for guiding only the upper side of the panel, and as an embodiment thereof, the panel guide means is substantially L-shaped and one side is cut off. An opening is formed by bending a panel mounting tool whose end is bent and a sheet metal flat plate provided above the inside of the housing and having a T-shaped hole and a T-shaped hole on the T-shaped neck. inserted Yo is composed of a T-shaped under-neck portion of the holes and molded guide bracket on the opposite side bent in a Z-shape each of which, in front of the openings of the guide bracket to one side bent in zigzag in the panel fixture and by mounting the panel to the housing while sliding, Runode not only guide the upper side of the panel, when using a mounting structure of a panel system in a narrow housing frontage of communication equipment, It is possible to effectively utilize the space in the body, has the effect that it is possible to improve the mounting efficiency in the housing.

In addition, there is no mechanical obstacle in connecting an external cable or the like directly to the panel from the outside of the housing, so that the external cable or the like can be easily routed and the number of members can be reduced. Is reduced.

Further, since the guide structure on the lower side of the panel is eliminated, not only the space for mounting the guide member at the lower portion of the panel can be eliminated, but also the improvement of the component mounting area on the substrate and the restriction on the component mounting space. This has the effect of enabling reduction of the amount.
