[0004] The above-mentioned method of interfering and holding the upper cover and the lower frame has been used in the industry for a long time, and has a good practical effect, but there are also unfavorable factors that affect the stability and accuracy of its use.
Due to the limitations of the manufacturing process, the interference protrusions and interference holes stamped on the clamping piece with a small surface area and the fixed side frame usually cause the interference of the two due to insufficient precision of the stamping position or insufficient size accuracy. The holding position is not accurate, the holding force is not enough, so that the entire upper cover is not fixed stably, the service life of the shielding structure is greatly shortened, and its ability to shield electromagnetic waves will be affected accordingly
Moreover, under the current trend of miniaturization of handheld devices, this method of holding through holes and protrusions hinders the use of two-piece shielding structures in small handheld devices because the height of the product is limited by the through holes and protrusions. application

Embodiment Construction
[0012] see figure 1 , figure 2 and image 3 As shown, the shielding structure 1 of an electronic device mainly includes a protective top surface 10 and a fixed side frame 20 .
[0013] The protective top surface 10 is a rectangular plate-shaped structure made of a metal material. The protective top surface 10 is provided with an upper surface 101 and a lower surface 102 opposite thereto. There are several through holes 103 , and the two sides in the length direction and one side in the width direction of the protective top surface 10 protrude from the upper surface 101 to provide protrusions 104 . The other side of the width direction of the protective top surface 10 is recessed to form a recessed space (not marked). In this recessed space, a clamping elastic piece 105 is extended from the protective top surface 10. The free end of the clamping elastic piece 105 is bent and A locking portion 106 protrudes toward the lower surface 102 of the protective top surface 10 .

The invention discloses a shielding structure of an electronic device and the shielding structure is used to be arranged on a circuit board to shield the electronic devices arranged on the circuit board. The shielding structure comprises a protective top surface and a fixing side frame, wherein the fixing side frame is provided with a side frame which is separated from the assembled circuit board, the side edge of the side frame extends to form a side wall and shield the space between the side frame and the circuit board, wherein the side frame is provided with a positioning plate to form an inserting space in which the protective top surface is inserted from the first edge of the fixing side frame along a direction parallel to the circuit board; and the protective top surface is insertedin the inserting space.
Description
【Technical field】 [0001] The invention relates to a shielding structure of an electronic device, in particular to a shielding structure of a detachable electronic device. 【Background technique】 [0002] Electromagnetic interference is one of the common problems in electronic communication equipment. Usually conductive loops and signal paths will radiate electromagnetic waves of a certain frequency when current passes through them. If the frequency of these electromagnetic waves is similar to or the same as the operating frequency of other electronic components, then It will affect the signal transmission and working performance of these electronic components. If this electromagnetic wave is generated in some communication devices that need to transmit signals through electromagnetic waves, such as mobile phones, it will have a greater impact on the call quality. [0003] In order to reduce or eliminate this undesirable electromagnetic interference, a shielding structure of a...
