Description

Plug-in box

Technical Field

The utility model relates to a communication equipment technical field, in particular to subrack.

Background

In the existing inserting box type product, the positioning of the back plate assembly is mostly completed by the guide rails on two sides of the box body and the guide of the sheet metal structural member and the guide and positioning between the bottom guide pin and the sheet metal. Because the box uses the bottom plate of box as the benchmark on the whole, every layer of overlap joint between backplate subassembly and the bottom plate increases, and the error that panel beating, installation etc. produced will increase. The more sheet metal processing procedures, the more structural member stacking layers and the larger accumulated error are, so that the connection precision of the back plate and each functional module is directly reduced, and serious hidden danger is buried for the reliability of the whole machine product.

As shown in fig. 1, fig. 1 is a schematic perspective view of a conventional subrack. The plug-in box comprises a box body 100 and a back plate assembly 300 arranged in the box body 100; the box body 100 comprises a bottom plate 110, two side plates 130 vertically connected to the bottom plate 110 and oppositely arranged, and an upper cover 150 connected to the side plates 130 and oppositely arranged with the bottom plate 110; the inner surface of the side plate 130 is provided with a guide rail 131, and the upper cover 150 is provided with a positioning hole 151; one end of the back plate assembly 300 away from the bottom plate 110 is provided with a positioning pin 311; the backboard assembly 311 is inserted into the box body 100 along the guide rail 131, and the positioning pin 311 is inserted into the positioning hole 151, so as to realize the positioning and installation of the backboard assembly 300 and the box body 100.

However, since the box body 100 is formed by U-shaped bending of a sheet metal part, when the box body is bent, a bending error exists between the side plate 130 and the bottom plate 110, so that the bending accuracy between the side plate 130 and the bottom plate 110 cannot be effectively ensured, and the rear end of the upper cover 150 is of a cantilever structure and has low rigidity, and the upper cover 150 is installed on the basis of the side plate 130, so that the installation error is accumulated. When the backplate assembly 300 is positioned and mounted with reference to the upper cover 150, the mounting accuracy of the backplate assembly 300 is difficult to ensure due to large accumulated errors.
