A protective shell

Abstract

This utility model discloses a protective housing, including an upper housing and a lower housing. The upper housing is detachably mounted on the lower housing. An AC input connector is provided on the upper surface of the upper housing, and several mounting holes 'a' are also formed on the surface of the upper housing. A mounting seat corresponding to the mounting holes 'a' is provided inside the lower housing. A mounting cylinder is screwed onto the end of the mounting seat, and a mounting groove is formed on the mounting cylinder, with a threaded section on the mounting groove. The beneficial effects of this utility model are: by placing the power supply equipment inside the lower housing and then placing the upper housing on the lower housing, the mounting cylinder is positioned within the mounting holes 'a' and fixed with bolts. At the same time, the upper and lower housings are fixed around their perimeter with screws, thereby forming a closed cavity. This isolates the noise of the power supply equipment, reduces electromagnetic radiation harm to operators, and also reduces interference with surrounding modules.

Description

Technical Field

[0001] This utility model relates to the field of electromagnetic protection technology, and in particular to a protective shell. Background Technology

[0002] Power supply equipment is an essential component in modern computer rooms, communication systems, power control systems, AC / DC power supply systems, and new energy conversion systems, providing operating power or uninterrupted backup power to system equipment. Currently, most existing power supply equipment is exposed, with few incorporating electromagnetic radiation shielding. While this design facilitates maintenance, the electromagnetic waves generated during operation leak and radiate through the exposed plastic parts, posing a potential health hazard to on-site operators.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this embodiment, as Figure 1 As shown, a protective housing includes an upper housing 1 and a lower housing 2. The upper housing 1 is detachably mounted on the lower housing 2. An AC input connector 7 is provided on the upper surface of the upper housing 1. Several mounting holes a8 are also formed on the surface of the upper housing 1. A mounting base 11 corresponding to the mounting holes a8 is provided inside the lower housing 2. A mounting cylinder 12 is screwed onto the end of the mounting base 11, and a mounting groove with a threaded section is formed on the mounting groove. A power supply device is placed inside the lower housing 2, and then the upper housing 1 is placed on top of the lower housing 2, so that the mounting cylinder 12 is located within the mounting holes a8 and fixed with bolts. Screws 6 are also used to fix the upper housing 1 and lower housing 2 around their perimeter, thus forming a closed cavity. This isolates noise from the power supply device, reduces electromagnetic radiation harm to operators, and also reduces interference with surrounding modules. Furthermore, the closed cavity isolates high-voltage and low-voltage areas, avoiding the risk of arcing and breakdown. In this embodiment, the AC input connector 7 is an existing device and has not been modified; therefore, it will not be described in detail. Figure 3 As shown, several interfaces 9 are also provided on the upper housing 1, through which the required devices can be connected.

[0021] Furthermore, such as Figure 2As shown, a step 10 is provided inside the lower housing 2, and a mounting base 11 is disposed on the step 10. Specifically, the main function of the step 10 is to raise the power supply equipment, allowing more existing components to be placed on the lower layer of the step 10, thereby enhancing integration and meeting product requirements.

[0022] Furthermore, the upper housing 1 has several grooves 5 on its side, and mounting holes b are formed within the grooves 5. The upper surface of the lower housing 2 has mounting holes c13 corresponding to the mounting holes b. Specifically, the upper housing 1 is placed on the lower housing 2, so that the mounting cylinder 12 is located within the mounting hole a8 and fixed with bolts. At this time, the mounting holes b and c are also aligned, and then fixed with screws 6, thereby forming a closed cavity. In this embodiment, the main function of the mounting cylinder 12 and the mounting hole a8 is to provide a reference for quick installation.

[0023] In this embodiment, a groove b3 is provided on the side of the lower housing 2, and a groove c corresponding to the groove b3 is provided on the side of the upper housing 1. A mounting hole d4 is provided at the bottom of the groove b3. Specifically, the main function of the mounting hole d4 is to install and fix the protective housing onto the corresponding equipment.

[0024] Furthermore, the surfaces of the upper housing 1 and the lower housing 2 are coated with an anti-corrosion coating. Specifically, by coating the surfaces of the upper housing 1 and the lower housing 2 with an anti-corrosion coating, the reliability of the metal cavity in humid and salt spray environments is improved.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
