Description

Technical Field

[0001] The utility model relates to the technical field of industrial engineering equipment accessories, in particular to a slot cover plate for a high-frequency switching power supply module. Background Art

[0002] As the DC power supply source of communication equipment, the high-frequency switching power supply plays an indispensable key role in the communication system. With the continuous development of technology, various communication equipment has become increasingly integrated and miniaturized, requiring the power supply equipment to be miniaturized accordingly for flexible configuration within the site. Since the rectifier modules of high-frequency switching power supplies are iterated rapidly and their sizes have been decreasing generation by generation, there are size differences between each generation of products and products with different powers. Moreover, the maximum capacity of the power supply system has a redundant design and usually does not configure all modules at full power. To ensure that the air flow channel of the power supply system meets the requirements of the overall heat dissipation design, the reserved module slots must be equipped with cover plates to avoid air flow "short circuit". Due to the size differences of modules with different versions and powers, there are also various non-universal specifications for the slot cover plates. At the same time, due to the diversity of end-user requirements, a large number of slot cover plates of various specifications are often used. The fixing methods of different specifications of slot cover plates are different. Typically, there are mainly two types. One is to fix through the buckle holes on the upper bottom plate of the power supply box and the buckle feet of the cover plate, and the other is to fix through the fixing ears on the side wall of the power supply box and the buckle feet of the cover plate. The cover plates using these two fixing methods cannot be universal. This not only causes trouble in use but also leads to an increase in cost. Content of the Utility Model

[0003] Aiming at the defects existing in the prior art, the utility model provides a universal slot cover plate for a high-frequency switching power supply module with strong practicability, convenient use and adaptable to power supply boxes with different fixing methods.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: A universal slot cover plate for a high-frequency switching power supply module, which is fixed at the slot of the power supply box of the high-frequency switching power supply module. A number of first fixing feet and a number of second fixing feet are arranged on the inner side surface of the cover plate. Both the first fixing feet and the second fixing feet have hooks. The first fixing feet are opposite to the buckle holes on the power supply box, and the second fixing feet are opposite to the fixing ears inside the power supply box. When the cover plate is installed, for a power supply box with buckle holes, it is fixed by buckling the first fixing feet with the buckle holes of the power supply box. Or for a power supply box with fixing ears, it is fixed by buckling the second fixing feet with the fixing ears of the power supply box.

[0005] Further, the second fixing feet include at least four, which are respectively arranged at positions close to the four corners on the inner side of the cover plate. For the power supply box with fixing ears, the fixing ears are respectively arranged at positions close to the four corners on the inner side surfaces of the two side walls of the power supply box, and each fixing ear extends towards the middle of the power supply box. When the cover plate is installed, it is fastened and fixed to the cover plate by the hooks of the second fixing feet buckling with the fixing ears.

[0006] Further, the first fixing feet include at least four, and each first fixing foot is respectively arranged at a position on the inner side surface of the cover plate adjacent to the second fixing feet, and the second fixing feet are located on the outer side while the first fixing feet are located on the inner side, and the positions of the first fixing feet are higher than those of the second fixing feet; for the power supply box with buckling holes, the buckling holes are respectively arranged at positions close to the four corners on the top plate and the bottom plate of the power supply box. When the cover plate is installed, it is fastened and fixed to the cover plate by the hooks of the first fixing feet buckling into the buckling holes.

[0007] Further, a retaining edge is arranged on the inner side of each second fixing foot. After the second fixing foot is buckled with the fixing ear, the front edge of the fixing ear is buckled by the hook of the second fixing foot and the inner side edge of the fixing ear is resisted by the retaining edge.

[0008] Further, the retaining edge and the hook of the second fixing foot are connected to each other and form a 90-degree angle to improve the stability of buckling with the fixing ear.

[0009] Further, clamping edges are arranged on both the upper edge and the lower edge of the cover plate. When the cover plate is installed on the power supply box, the upper and lower clamping edges respectively clamp the upper and lower edges of the slot to improve the stability and sealing performance.

[0010] Further, the first fixing feet and the second fixing feet are of an integral structure with the cover plate and can be integrally formed with a plastic material.

[0011] Through the combined action of the limiting and fixing structures of the upper and lower edges and the four-corner hook fixing feet of the present utility model, the compatibility and matching with power module slots of different sizes and specifications can be realized; the cover plate is of an integrated design and has two types of fixing feet, which can be used for different fixing methods without screw fastening installation, and the disassembly and assembly are simple and fast, and a general effect can be achieved.
