Description

Technical Field

[0001] The utility model belongs to the technical field of direct current power supply protection modules, in particular to a high-frequency direct current power supply protection module. Background Art

[0002] A DC power supply is a device that maintains a steady voltage and current in a circuit, such as a dry cell, storage battery, or DC generator.

[0003] According to a DC power supply protection module disclosed in the patent publication number CN116436255A, by setting a protective bottom frame and a protective top frame, and using connecting bolts and limit clamps, the protective bottom frame, the protective top frame and the DC power supply protector can be fixed at the same time, so that the DC power supply protector is protected by the protective bottom frame and the protective top frame to prevent the DC power supply protector from being damaged. However, there are still the following deficiencies, such as:

[0004] Since the device is provided with a ventilation dustproof plate and has many heat dissipation holes on the surface, the dust-proof effect of this method is poor. When not in use, external dust can easily enter the DC power supply protector through the heat dissipation holes. Long-term accumulation will cause dust to adhere to the internal control board, which is prone to poor contact during use. In severe cases, it will cause damage and economic losses. Therefore, we propose a high-frequency DC power supply protection module. Utility Model Content

[0005] The purpose of the utility model is to provide a high-frequency DC power supply protection module. By setting a dustproof component, the dust can be reduced from entering the power supply protector through the heat dissipation port, thereby increasing the service life of the power supply protector. At the same time, the clamp block will push the dustproof plate downward under the elastic action of the spring piece, so that the dustproof plate and the power supply protector are in close contact, thereby improving the dustproof effect. The problem that the existing power supply protection module easily allows external dust to enter the interior, and long-term accumulation will cause dust to adhere to the internal control board, which is prone to poor contact during use, and may cause damage in serious cases.

[0037] A specific application of this embodiment is:

[0038] When in use, the mounting base 1 is installed in the control cabinet, and then the power supply protector 11 is plugged into the mounting base 1. The positioning block 13 is used to position the power supply protector 11. At the same time, the mounting block 114 on the connecting block 111 can be accurately plugged into the mounting base 1, and then the turning handle 16 is turned to drive the bevel gear 2 163 to rotate forward through the turning rod 161, and the bevel gear 2 163 drives the bevel gear 1 143 to rotate reversely, thereby causing the rotating shaft 142 to rotate reversely. Since the rotating shaft 142 and the threaded rod 144 are threadedly connected, and the two threaded rods 144 are arranged with opposite threads, the rotation of the rotating shaft 142 will respectively drive the two threaded rods 144 to approach or move away from each other, and through the reverse rotation of the rotating shaft 142, the two threaded rods 144 will drive the two push blocks 145 to move away from each other, and the limiting block 15 can limit the push block 145, so that the push block 145 makes a linear motion.

The power protector 11 is tightly attached to the mounting base 1, and the power protector 11 can be fixed without using screws. The installation is convenient and not easy to be damaged. When the power protector 11 is not in use, the push plate 123 is pulled to drive the dustproof plate 121 to move to the right, and the dustproof plate 121 slides on the limit rail 115 through the slide rail 124, so that the dustproof plate 121 seals the top of the power protector 11, which can reduce the dust from entering the power protector 11 through the heat dissipation port, thereby improving the service life of the power protector 11. At the same time, the clamping block 31 will push the dustproof plate 121 downward under the elastic action of the spring piece 32, so that the dustproof plate 121 is tightly attached to the power protector 11, and the dustproof effect is improved. The movement of the dustproof plate 121 will not be affected, and the dustproof plate 121 can be prevented from moving by itself. When the power protector 11 needs to be used, the dustproof plate 121 is pushed to the left to expose the heat dissipation port on the top of the power protector 11, so that heat can be dissipated during use, which is more practical.
