Description

Technical Field

[0001] This utility model relates to the field of DC power supplies, and in particular to a modular desktop DC power supply. Background Technology

[0002] Prefabricated benchtop DC power supplies are commonly used power devices in laboratories, research and development, maintenance, and testing. They provide stable DC voltage and current. Prefabricated benchtop DC power supplies have a modular design, allowing users to flexibly configure the output voltage and current for more precise power control.

[0003] Existing modular desktop DC power supplies release a large amount of heat during use and are equipped with heat exchange devices to dissipate the internal heat. However, the heat dissipation openings of DC power supplies cannot filter the incoming air. In humid areas, the air contains a lot of moisture, which increases the conductivity between electrical components, leading to electrical faults such as short circuits, thus affecting the normal operation of the power supply. Utility Model Content

[0004] The main objective of this invention is to provide a modular desktop DC power supply that can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] As a further embodiment of this utility model, the connecting assembly includes a plurality of connecting grooves formed on the filter plate, the plurality of connecting grooves being distributed at the top corner of the filter plate, and a plurality of connecting posts being fixedly connected to one side of the cover plate, with one end of each of the plurality of connecting posts passing through the plurality of connecting grooves.

[0008] As a further embodiment of this utility model, the connecting assembly further includes a fixing groove formed on the connecting column, and a fixing rod is slidably disposed in the fixing groove.

[0009] As a further embodiment of this utility model, a threaded groove is provided on one side of the fixing rod, and a bolt is provided on the connecting column, with one end of the bolt threadedly connected to the threaded groove.

[0010] As a further embodiment of this utility model, each of the connecting columns is provided with an installation cavity, a spring is fixedly connected inside the installation cavity, and a positioning block is fixedly connected to the other end of the spring.

[0011] As a further embodiment of this utility model, a positioning hole is provided on one side of the connecting groove, and the positioning hole is adapted to the positioning block.

[0012] As a further embodiment of this utility model, the power supply box is provided with a plurality of air inlets and a plurality of exhaust outlets, and the plurality of air inlets and exhaust outlets are evenly spaced in an array.

[0013] The beneficial effects of this utility model are as follows:

[0014] A filter plate is installed on the outside of the power supply box, and then the filter plate is fixed to the power supply box by the connecting assembly. Air first enters the filter chamber through the filter holes. The moisture in the air is first filtered by the moisture-absorbing cotton, and then further absorbed by the activated carbon plate. Then it enters the power supply box through the filter holes on the other side to remove the moisture in the air. This prevents large amounts of moisture in the air from entering the power supply, thereby preventing moisture from increasing the conductivity between electrical components, avoiding electrical faults such as short circuits, and ensuring that the power supply can work normally.

[0015] After the connecting post is inserted into the connecting groove, the spring inside the cavity is installed first, and one end of the positioning block is pushed into the positioning hole, thereby restricting the filter plate on the connecting post and limiting the position of the filter plate to prevent it from shaking, which facilitates the subsequent installation of the fixing rod.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-6 As shown, a prefabricated desktop DC power supply includes a power supply box 1. A cover plate 2 is fixedly connected to one side of the power supply box 1. A filter plate 5 is provided on the outside of the power supply box 1. The filter plate 5 has a plurality of filter chambers 6, which are distributed in an array at equal intervals. An activated carbon plate 8 is provided inside the filter chamber 6. Two sets of moisture-absorbing cotton 7 are provided on the inner wall of the filter chamber 6. The two sets of moisture-absorbing cotton 7 are symmetrically distributed about the central axis of the filter chamber 6. One side of the two sets of moisture-absorbing cotton 7 is attached to both sides of the activated carbon plate 8.

[0025] In this embodiment, the filter plate 5 is provided with a plurality of filter holes 9, which are distributed in an array at equal intervals. The cover plate 2 is provided with a connecting component, which is used to connect the filter plate 5 to the power supply box 1.

[0026] To prevent excessive moisture from entering the power supply box 1, the filter plate 5 is first fitted onto the outside of the power supply box 1, and then the filter plate 5 is fixed to the power supply box 1 by the connecting assembly. Air first enters the filter chamber 6 through the filter hole 9. The moisture in the air is first filtered by the moisture-absorbing cotton 7, and then further absorbed by the activated carbon plate 8. Finally, it enters the power supply box 1 through the filter hole 9 on the other side to remove the moisture in the air. This prevents a large amount of moisture from entering the power supply, thereby preventing moisture from increasing the conductivity between electrical components, avoiding electrical faults such as short circuits, and ensuring that the power supply can work normally.

[0027] The power supply box 1 has several air inlets 3 and several exhaust ports 4. The air inlets 3 and several exhaust ports 4 are evenly spaced and arranged in an array. The power supply box 1 dissipates the heat generated inside the power supply box 1 through the air inlets 3 and exhaust ports 4, thereby avoiding internal overheating.

[0028] In this embodiment, the connecting component includes a plurality of connecting grooves 11 formed on the filter plate 5, the plurality of connecting grooves 11 being distributed at the top corner of the filter plate 5, a plurality of connecting posts 10 being fixedly connected to one side of the cover plate 2, one end of each of the plurality of connecting posts 10 passing through the plurality of connecting grooves 11, the connecting component also includes a fixing groove 12 formed on the connecting posts 10, a fixing rod 13 being slidably disposed in the fixing groove 12.

[0029] When the filter plate 5 is fitted onto the power supply box 1, first align the connecting post 10 with the connecting groove 11, then insert the connecting post 10 into the connecting groove 11 to restrict the position of the filter plate 5. Then insert the fixing rod 13 into the fixing groove 12 to fix the position of the filter plate 5, preventing the filter plate 5 from falling off the power supply box 1, thereby increasing the convenience of component connection.

[0030] Meanwhile, a threaded groove is provided on one side of the fixing rod 13, and a bolt 14 is provided on the connecting column 10. One end of the bolt 14 is threadedly connected to the threaded groove. When the fixing rod 13 is inserted into the fixing groove 12, and one end of the bolt 14 is connected to the threaded groove of the fixing rod 13, the fixing rod 13 is fixed in the fixing groove 12, thereby the fixing rod 13 is reliably connected to the connecting column 10.

[0031] In this embodiment, each of the connecting posts 10 has an installation cavity 15, a spring 16 is fixedly connected in the installation cavity 15, and a positioning block 17 is fixedly connected to the other end of the spring 16. A positioning hole 18 is provided on one side of the connecting groove 11, and the positioning hole 18 is adapted to the positioning block 17.

[0032] After the connecting post 10 is inserted into the connecting groove 11, the spring 16 in the cavity 15 is installed first, and one end of the positioning block 17 is pushed into the positioning hole 18, thereby restricting the filter plate 5 on the connecting post 10, restricting the position of the filter plate 5, and preventing the filter plate 5 from shaking, so as to facilitate the subsequent installation of the fixing rod 13.

[0033] It should be noted that this utility model is a prefabricated desktop DC power supply. To prevent excessive moisture from entering the power supply box 1, the filter plate 5 is first fitted onto the outside of the power supply box 1. Then, the connecting post 10 is aligned with the connecting groove 11, and the connecting post 10 is inserted into the connecting groove 11, thereby restricting the position of the filter plate 5. The fixing rod 13 is then inserted into the fixing groove 12, and one end of the bolt 14 is connected to the threaded groove of the fixing rod 13, fixing the fixing rod 13 in the fixing groove 12. This securely connects the fixing rod 13 to the connecting post 10, thus fixing the position of the filter plate 5. Air first enters the filter chamber 6 through the filter hole 9. The moisture in the air is first filtered by the moisture-absorbing cotton 7, then further absorbed by the activated carbon plate 8, and then enters the power supply box 1 through the filter hole 9 on the other side to remove the moisture in the air.
