Problems solved by technology

[0005] The disadvantage of the prior art is that two different molds need to be used to stamp the shielding cover and the shielding frame respectively, and a special structure needs to be designed for fixing the shielding cover in the electronic product, which is inconvenient for loading and unloading when the electronic product is being maintained, and There will inevitably be large or small gaps in the lock structure after assembly, and electromagnetic waves will leak from these gaps in actual use

Embodiment Construction

[0020] The specific implementation of the electromagnetic shield provided by the present invention will be given below in conjunction with the accompanying drawings.

[0021] figure 2 It is a structural schematic diagram of the electromagnetic shielding cover described in this specific embodiment, including a shielding cover 21 and a shielding frame 22, the shielding cover 21 is made of metal conductive shielding tape, and the shielding frame 22 is adhered to the surface of the shielding cover 21 . The electromagnetic shielding cover provided in this specific embodiment is specially used in mobile phones.

[0022] The electromagnetic shield described in this specific embodiment has a width of 19.58 mm, a length of 24.73 mm, and a thickness of 1.15 mm. In the prior art, if a shielding cover is formed by stamping a metal plate, in the case of using a shielding frame 22 of the same size, the width of the obtained electromagnetic shielding cover is 19.84mm due to the thickness ...

Abstract

The present invention discloses an electromagnetic shielding cover, comprising a shielding frame and a shielding lid. The shielding lid is made from a metallic conduction shielding adhesive tape. The shielding frame is adhered to the surface of the shielding cover. The shielding cover has the advantages that the shielding cover can reduce the material cost, the labor cost and the quality inspection cost of the manufacture, the size of the shielding cover can be reduced, the electromagnetic leakage due to the gap between the shielding lid and the shielding cover can be avoided, and the handling operation is simple and convenient.

Description

【Technical field】 [0001] The invention relates to the field of electronic product manufacturing, in particular to an electromagnetic shielding cover. 【Background technique】 [0002] With the increasing development of mobile communication technology and various other microwave communication technologies, people's living space is filled with increasingly dense electromagnetic waves of various bands. For mobile phones and other consumer electronics products, electromagnetic waves in the space can easily interfere with the normal operation of their internal circuits, causing abnormal operation of the internal circuits, causing performance degradation or even failure of electronic products. [0003] In mobile phones and other various consumer electronics products, in order to shield the external electromagnetic wave noise from interfering with the internal circuit, it is usually necessary to use a special electromagnetic shielding cover to shield the external noise electromagneti...
