[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] To address the problems existing in the prior art, this embodiment provides the following technical solution: a power supply switch comprising a housing 1, an installation plate 3 installed inside the housing 1, an installation facilitator 5 and a control component 41 at the front end of the installation plate 3, and a control component 41 arranged in multiple groups at equal intervals on the front side of the installation facilitator 5, thus integrating multiple functional control components together. This effectively saves internal space in the housing 1, reduces the overall size of the housing 1, achieves miniaturization of the overall equipment volume, and reduces material costs. Simultaneously, the installation facilitator 5 is provided on the outside of the control component 4, enabling precise alignment and installation of the control component 4, and facilitating subsequent disassembly, replacement, and maintenance of the control component 4.

[0028] like Figures 1-7 As shown, a power supply switch is provided with a housing 1, and an mounting plate 3 is installed inside the housing 1. The mounting plate 3 is an aluminum alloy substrate with high thermal conductivity.

[0029] An installation facilitator 5 is fixedly installed on the upper front side of the mounting plate 3. The installation facilitator 5 is located on the outside of the control component 4. The control components 4 are arranged in multiple groups at equal distances on the front side of the installation facilitator 5. The mounting plate 3 acts as a heat spreader, which enables the heat source of the connected components to spread quickly. The outer side of the mounting plate 3 is in close contact with the outer shell 1, which can conduct heat to the entire outer shell 1 and accelerate the dissipation of heat. At the same time, a control component 2 41 is also provided on the lower front side of the mounting plate 3.

[0030] The installation mechanism 5 includes a magnetic block 51 located at the rear end of the middle of each control component 4. The rear end of the magnetic block 51 is magnetically connected to a magnetic port 52. The magnetic ports 52 are equally spaced inside the mounting groove 53. The mounting groove 53 is located inside the mounting block 54. The rear end of the mounting block 54 is fixedly connected to the mounting plate 3. Fixing posts 55 are fixedly installed on the left and right sides of the outside of the mounting block 54. Limiting elements 56 are slidably provided on the outside of the fixing posts 55. Bolts 57 are provided inside the left and right ends of the limiting elements 56.

[0031] The magnetic block 51 is a permanent magnet, and magnetic suction ports 52 are set on the rear side. The magnetic suction port 52 is equipped with a magnetic chip. The adjacent surfaces of the two are opposite and attract each other, which can generate magnetic attraction. The magnetic suction port 52 is set inside the mounting groove 53 opened inside the mounting block 54. At this time, the control component 4 will be pre-positioned and installed on the front side of the mounting block 54. This setting can make the control component 4 accurately positioned on the front side of the mounting block 54, effectively avoiding the occurrence of installation offset.

[0032] Then pull the limiting member 56 that is slidably set on the outside of the fixing column 55 symmetrically installed on the left and right sides of the mounting block 54 and move it inward so that the inner side of the limiting member 56 fits with the upper and lower ends of the control component 4. The upper side of the inner side of the left and right sides of the limiting member 56 has a round hole and the lower side has a threaded hole, which are vertically aligned. After the limiting member 56 is adjusted, the bolt 57 can be inserted into the inner side of the two to tighten the limiting. At this time, the limiting member 56 can limit the position of the control component 4 for a second time, which can ensure the stability of the control component 4 installed on the front side of the mounting block 54.

[0033] If the control component 4 needs to be replaced or maintained in the future, the bolt 57 can be unscrewed and pulled out of the inside of the limiting member 56. At this time, the limiting member 56 will separate from the attached control component 4. Then, hold the control component 4 and pull it forward to remove the control component 4 from the front of the mounting block 54.

[0034] In addition, a dustproof component 2 is provided on the front side of the outer casing 1. Some outer casings 1 on the market adopt a semi-enclosed design. Such a design will cause a large amount of dust to be absorbed and accumulated inside the outer casing 1 over a long period of time. The accumulation of dust will cause short circuits in the internal components of the outer casing 1. By setting the dustproof component 2, a large amount of dust can be blocked from entering the interior of the outer casing 1, which can protect the internal components of the outer casing 1.

[0035] The dustproof component 2 includes a dustproof mesh 21 that is slidably disposed inside the front side of the housing 1. The lower side of the dustproof mesh 21 is engaged with a locking port 22, which is symmetrically opened on the lower side of the housing 1. The upper middle part of the dustproof mesh 21 is fixedly connected to the middle part of the connecting block 23 by bolt 2. The connecting block 23 is fixedly disposed on the upper front side of the middle part of the housing 1. Specifically, a round hole is opened on the upper middle part of the dustproof mesh 21, and a threaded hole is opened in the middle part of the connecting block 23. When the lower side of the dustproof mesh 21 is engaged with the locking port 22, the round hole opened on the upper middle part of the dustproof mesh 21 will fit with the threaded hole in the middle part of the connecting block 23. At this time, bolt 2 can be inserted into the interior of both for limiting.

[0036] When it is necessary to operate the internal components of the outer casing 1, the bolts securing the dustproof net 21 and the connecting block 23 can be unscrewed and pulled out. Then, the dustproof net 21 can be pulled upwards, and the bottom of the dustproof net 21 will disengage from the engaging slot 22. Pull the dustproof net 21 out of the front of the outer casing 1, and then the internal components of the outer casing 1 can be operated. After the operation is completed, the dustproof net 21 can be reinstalled back into the front of the inner side of the outer casing 1.

[0037] In addition, a temperature sensor 6 (model DS18B20) is installed on the right side of the inner wall of the outer casing 1. Furthermore, fans 7 are arranged horizontally at equal intervals on the rear wall of the outer casing 1. An air inlet 8 is provided in the middle of each fan 7. The air inlet 8 is located inside the rear wall of the outer casing 1, and a dustproof screen is installed inside the air inlet 8.

[0038] Temperature sensor 6 can detect the temperature inside the housing 1. Once temperature sensor 6 detects that the temperature inside the housing 1 exceeds the preset value, it can transmit a signal to the control circuit, thereby triggering the fan 7 to start. The fan 7 can quickly blow the heat inside the housing 1 out from the front of the housing 1, which can accelerate the heat dissipation.

[0039] The working principle of this power supply switch is as follows: An installation plate 3 is set inside the housing 1. An easy-installation mechanism 5 and a control component 41 are installed on the front side of the installation plate 3. Multiple control components 4 are installed at equal intervals on the front side of the easy-installation mechanism 5. The control components 4 are compactly arranged together with the control components 41, which can effectively eliminate the waste of space when assembling multiple independent components, achieve high-density integrated installation, and reduce the overall volume of the housing 1, thereby reducing the material cost of the equipment. At the same time, the easy-installation mechanism 5 set on the outside of the control components 4 can achieve precise pre-positioning of the control components 4 in the narrow space of the housing 1 through magnetic attraction, which can effectively avoid the occurrence of misalignment during installation. Then, it can be fixed by secondary limiting. In addition, the magnetic attraction makes it convenient for the subsequent disassembly and replacement of the control components 4.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
