Embodiment Construction

[0012] see Figure 1 to Figure 3 , the electromagnetic shielding cover 100 is used to shield the electronic components (not shown) on the circuit board 20 to shield electromagnetic waves. The electromagnetic shielding cover 100 includes a first cover 30 and a second cover 40 rotatably connected to the first cover 30 , the first cover 30 and the second cover 40 form a closed cover.

[0013] The first cover 30 includes a top surface 301 , a side plate 302 and an opening 310 . The side panel 302 is bent and extended around the top surface 301 , and the opening 310 passes through the side panel 302 to reach the top surface 301 . The first cover 30 is fixed on the circuit board 20 , and in this embodiment, the first cover 30 is fixedly combined with the circuit board 20 by welding.

[0014] The second cover 40 covers the opening 310 , and the second cover 40 includes a main body 401 , a bent portion 402 and a hook 410 . One end of the body 401 is movably connected to the first c...

Abstract

A shielding is fixed on a circuit board and is used for shielding electromagnetic interference generated by electric elements on the circuit board. The shielding board includes a first cover and a second cover. The first cover and the second cover define an enclosed cover body. The first cover is provided with an opening. The second cover is disposed in the opening and one end of the second cover is in rotary connection with the first cover. The second cover is provided with a supporting block. The first cover does not contact with the electric elements. The supporting block contacts with the electric elements. By the rotary connection of the first cover and the second cover and the hook design of the second cover, the simple structure is realized and an aim of reducing cost is achieved.

Description

technical field [0001] The invention relates to a shielding case. Background technique [0002] General electronic equipment, such as televisions, computers, test equipment, etc., are equipped with numerous electronic components. When the electronic equipment is working, the electronic components will generate electromagnetic waves, which will not only cause electromagnetic interference between the internal electronic components and affect the normal operation of the electronic equipment, but also the electromagnetic waves will radiate outward, causing harm to the human body. Therefore, how to shield the electromagnetic waves generated by electronic components has become an urgent problem to be solved in the industry. However, the structure of the existing shielding case is complicated and the cost is high. Contents of the invention [0003] In view of this, the present invention provides a shielding case with a simple structure to save costs. [0004] The shielding cov...
