Description
Technical Field
[0001] This utility model relates to the field of power module technology, and in particular to a power module with a protective structure. Background Technology
[0002] A power module is a power supply that can be directly mounted on a printed circuit board. Its key feature is its ability to power application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads. Due to the numerous advantages of its modular structure, modular power supplies are widely used in communication fields such as switching equipment, access equipment, mobile communications, microwave communications, optical transmission, and routers, as well as in automotive electronics, aerospace, and other industries.
[0003] In the prior art, according to Chinese patent application number CN202222874857.9, a power module with a protective structure is disclosed, which includes a power module body, pins, and a protective shell. The bottom of the inner wall of the protective shell has several through holes, and the pins cooperate with the through holes. Tube shells are fixed in pairs on both sides of the power module body. A spring is fixed inside the tube shell, and a movable block is fixed to the other end of the spring. A movable rod is fixed to the other end of the movable block, and a fixed block is fixed to the other end of the movable rod. Fixed grooves are provided in pairs on both sides of the inner wall of the protective shell, and the fixed blocks are movably connected to the interior of the fixed grooves. This invention can block dust in the air, providing good protection and ensuring the normal operation of the module, indirectly improving its service life. It solves the problem that current power modules lack a protective structure, allowing dust to easily adhere to their surface and affect their normal operation.
[0004] In the prior art, according to Chinese patent application number CN202222874857.9, a power module with a protective structure is disclosed. However, after installation, the components that assist in disassembly are relatively close to the housing, affecting the efficiency of disassembly. Furthermore, the filter pores are only on the top layer of the housing, and the filtering effect tends to deteriorate after a period of use. Therefore, we propose a power module with a protective structure to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the power module with a protective structure disclosed in Chinese patent application number CN202222874857.9, where the self-disassembly auxiliary parts are close to the shell after installation, affecting the disassembly efficiency, and the filter holes on the shell alone are prone to deterioration in filtration effect after a period of use. Therefore, this utility model proposes a power module with a protective structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a power module with a protective structure, including a power module body, a shell, and a top cover. The power module body is located inside the shell.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figure 1-6 A power module with a protective structure includes a power module body 1, a housing 2, and a top cover 3. The power module body 1 is located inside the housing 2. The lower side of the housing 2 has several through holes, and filter holes are provided on both the left and right sides of the housing 2. The filter holes are used for heat dissipation inside the housing 2 and can filter the air, reducing the probability of dust entering the housing 2. The lower side of the power module body 1 is connected to a pin 9, which slides inside the through holes. The through holes have sealing rings to improve the sealing of the pin 9 and reduce the entry of dust into the housing 2 through the pin 9. The housing 2 and the top cover 3 are detachably connected. The module also includes: two C-shaped protective plates 4, two positioning blocks 5, two A-type filter plates 6, two auxiliary filter sections 7, and a quick-release connection unit 8.
[0029] The power module body 1 is fixedly connected to the inner side of the C-type protection plate 4. The lower side of the C-type protection plate 4 is provided with an A-type support block 10. A C-type support plate 11 slides on the outer side of the C-type protection plate 4. The C-type support plate 11 is connected to the inner side of the outer shell 2 and the A-type support block 10. The A-type support block 10 cooperates with the C-type protection plate 4 to install the power module body 1 on the inner side of the two C-type support plates 11. At the same time, the C-type protection plate 4 can prevent the C-type support plate 11 from directly contacting the power module body 1, which improves the safety of the device. The C-type protection plate 4 is wider than the PBC board on the power module body 1, which makes the power module body 1 more stable after installation.
[0030] The C-shaped support plate 11 has a positioning hole on one side, and the positioning block 5 can slide inside the positioning hole. The quick-release connection unit 8 is located between the two positioning blocks 5 and the two C-shaped protection plates 4. The quick-release connection unit 8 allows the power module body 1 to be quickly installed and removed. The quick-release connection unit 8 includes two mounting shells 81 and four springs 82. The mounting shells 81 are connected to the upper side of the C-shaped protection plates 4. The positioning blocks 5 can slide inside the mounting shells 81. The inner side of the mounting shells 81 is provided with a guide groove, and a guide block 83 slides inside the guide groove. The guide block 83 and the positioning block 5 are connected. The positioning block 5 is connected to the C-shaped support plate 11. Two blind holes are provided on the side away from the C-shaped support plate 11. The spring 82 is located inside the blind holes and inside the mounting shell 81. When the power module body 1 is installed, the positioning block 5 will contact the upper end of the C-shaped support plate 11. Under the action of the chamfer, the positioning block 5 is squeezed into the mounting shell 81. After the power module body 1 is installed in place, the positioning block 5 will enter the positioning hole under the action of the spring 82, realizing the positioning and installation of the power module body 1. This achieves the ability of rapid installation and improves the installation efficiency of the power module body 1.
[0031] A connecting rod 84 is provided inside the spring 82, and a sliding hole is provided on one side of the mounting shell 81. The connecting rod 84 can slide inside the sliding hole and is fixedly connected to the inside of the blind hole. An auxiliary plate 85 is provided between the two mounting shells 81. The auxiliary plate 85 is connected to the connecting rod 84. The connecting rod 84 slides in the sliding hole through the auxiliary plate 85. The connecting rod 84 will slide in the mounting shell 81 with the positioning block 5, allowing the positioning block 5 to slide out from the positioning hole, so that the power module body 1 can be disassembled, which improves the disassembly efficiency of the device.
[0032] The C-shaped support plate 11 is located between the two A filter plates 6. The A filter plates 6 can perform the first filtration of the air, reducing the probability of dust accumulating on the power module body 1. The left and right sides and front and rear ends of the A filter plates 6 are provided with limiting strips 12. The limiting strips 12 are connected to the inner side of the outer shell 2 and limit the power module body 1. The upper side of the two A filter plates 6 is provided with A pressure plate 13. The outer side of the A pressure plate 13 is connected with a sealing ring 14. The A pressure plate 13 is connected to the lower side of the upper cover 3. The A pressure plate 13 and the sealing ring 14 are on the upper side of the A filter plates 6 to seal the upper side of the A filter plates 6, reducing the probability of dust accumulating on the power module body 1.
[0033] The upper side of the C-shaped support plate 11 is provided with a positioning groove, and the B connecting plate 86 slides inside the positioning groove. The upper side of the two B connecting plates 86 is provided with a pressure strip 88, which is connected to the lower side of the A pressure plate 13. The pressure strip 88 can limit the B connecting plate 86, making the limiting plate 87 more stable. The auxiliary plate 85 is provided with a limiting plate 87 on the side away from the connecting rod 84. The limiting plate 87 is connected to the B connecting plate 86. The limiting plate 87 can limit the auxiliary plate 85, allowing the quick-release connecting unit 8 to be limited along with the positioning block 5, thereby improving the stability of the power module body 1 installation.
[0034] The auxiliary filter section 7 is located between the A filter plate 6 and the C-shaped support plate 11. The auxiliary filter section 7 is used for secondary filtration to improve the filtration effect. The auxiliary filter section 7 includes two filter strips 71 and two B filter plates 72. An A connecting plate 73 is fixed to the front side of the C-shaped support plate 11. Connecting blocks 74 are fixed to the upper and lower sides of the two B filter plates 72. The connecting blocks 74 are connected to the A connecting plate 73 and the inner side of the outer shell 2. The filter strips 71 and B filter plates 72 are connected to the inner side of the outer shell 2. The filter strips 71 and B filter plates 72 can provide secondary filtration for the inner side of the outer shell 2, reducing the probability of dust accumulation in the power module body 1 and improving the service life of the device. At the same time, the A connecting plate 73 and the connecting blocks 74 can support and fix the C-shaped support plate 11, improving the stability of the device.
