[0002] Electronic components are basic elements in electronic circuits, usually individually packaged and with two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with a specific function, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is to solder them to printed circuit boards. Electronic components may be individual packages or groups of varying complexity, such as operational amplifiers, resistors, logic gates, etc. Shielding covers are tools used to shield electronic signals. The function of a shielding cover is to shield the influence of external electromagnetic waves on the internal circuit and the radiation of electromagnetic waves generated internally.

It cannot meet the use requirements. Therefore, a shielding cover structure of an electronic component is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a shielding cover structure for electronic components, which has the advantages of good heat dissipation effect and strong practicality. It solves the problem that the existing electronic component shielding cover dissipates heat through heat dissipation fins, heat dissipation holes and multiple side heat dissipation holes on the frame, but during use, the internal electronic components are in an overheated state for a long time, which will lead to a reduction in the service life of the electronic components, seriously affecting the quality of the electronic components and failing to meet the use requirements.

[0010] Furthermore, the outer diameter of the micro fan is matched with the inner diameter of the protective cover, and a number of ventilation holes matching with the micro fan are provided inside the protective cover.

[0011] Furthermore, the mounting block is screwed to the top of the shielding cover, and the reset spring is connected to the outside of the elastic telescopic rod.

[0012] Furthermore, the number of the mounting block, the elastic telescopic rod, the connecting block and the reset spring is four, and the pressure-resistant plate is a soft rubber plate.

[0013] Furthermore, the shielding cover is a hollow cuboid and is made of titanium alloy.

[0014] Furthermore, the shielding cover and the base are snap-connected, and an electronic component body is arranged between the shielding cover and the base.

[0015] Compared with the prior art, the utility model provides a shielding cover structure for electronic components, which has the following beneficial effects:

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 In this embodiment, a shielding cover structure of an electronic component includes a base 1 and a shielding cover 2 arranged on the top of the base 1. A heat dissipation mechanism 3 extending to the inside of the shielding cover 2 is arranged on the outside of the shielding cover 2. A pressure-resistant component 4 is arranged on the top of the shielding cover 2. The heat dissipation mechanism 3 includes a micro fan 31 fixedly installed inside the shielding cover 2. A heat dissipation groove 33 is provided on the side of the inside of the shielding cover 2 away from the micro fan 31. Dustproof nets 32 are fixedly installed on the left and right sides of the outside of the shielding cover 2. A protective cover 34 fixedly connected to the inside of the shielding cover 2 is fixedly installed on the outside of the micro fan 31. The shielding cover 2 is a hollow rectangular parallelepiped, and the shielding cover 2 is made of titanium alloy. The shielding cover 2 and the base 1 are snap-connected, and an electronic component body is arranged between the shielding cover 2 and the base 1.

[0025] The micro fan 31 is started to rotate through the controller, and the micro fan 31 conveys wind to the inside of the shielding cover 2 through the air inlet hole. By setting the air inlet hole and the heat dissipation groove 33, it is convenient to dissipate heat and cool the electronic component body inside the shielding cover 2. By setting the protective cover 34, the micro fan 31 is prevented from affecting the electronic component body, thereby achieving the advantage of good heat dissipation effect.

[0026] An air inlet hole adapted to the micro fan 31 is provided inside the shielding cover 2 , and two dustproof nets 32 are respectively located outside the air inlet hole and the heat dissipation slot 33 .

[0027] It should be noted that the outer diameter of the micro fan 31 is matched with the inner diameter of the protective cover 34 , and a number of ventilation holes matching with the micro fan 31 are provided inside the protective cover 34 .

[0028] In this embodiment, the pressure-resistant assembly 4 includes a mounting block 41 fixedly connected to the top of the shielding cover 2, a side of the mounting block 41 away from the shielding cover 2 is fixedly connected to an elastic telescopic rod 42, a side of the elastic telescopic rod 42 away from the mounting block 41 is fixedly connected to a connecting block 43, a reset spring 44 is fixedly connected between the mounting block 41 and the connecting block 43, and a side of the connecting block 43 away from the shielding cover 2 is fixedly connected to a pressure-resistant plate 45. By providing the elastic telescopic rod 42 and the reset spring 44, when the pressure-resistant plate 45 is subjected to pressure, the elastic telescopic rod 42 and the reset spring 44 are deformed, thereby absorbing a large amount of energy, preventing the shielding cover 2 from being deformed at the bottom due to external impact, thereby preventing the electronic component body from being damaged, thereby achieving the advantage of strong practicality.

[0029] The mounting block 41 is screwed to the top of the shielding cover 2 , and the return spring 44 is connected to the outside of the elastic telescopic rod 42 .

[0031] The working principle of the above embodiment is:

[0032] When in use, the micro fan 31 is started to rotate through the controller, and the micro fan 31 conveys wind to the inside of the shielding cover 2 through the air inlet hole. By setting the air inlet hole and the heat dissipation groove 33, the electronic component body inside the shielding cover 2 is dissipated and cooled. By setting the protective cover 34, the micro fan 31 is prevented from affecting the electronic component body. When protecting the shielding cover 2, by setting the elastic telescopic rod 42 and the reset spring 44, the pressure-resistant plate 45 is deformed when it is subjected to pressure, thereby absorbing a large amount of energy, thereby preventing the bottom of the shielding cover 2 from being deformed due to external impact and causing damage to the electronic component body.

The device is powered by an external power supply.
