[0002] A mobile phone shielding cover is a device that uses a shielding body to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading outward.

[0003] The principle of a mobile phone shielding case is to use a shield to surround interference sources such as components, circuits, assemblies, cables, or the entire system to prevent the spread of interfering electromagnetic fields. The shield also surrounds receiving circuits, devices, or systems to protect them from external electromagnetic fields. Shielding cases are typically made of 0.2mm thick stainless steel and nickel silver.

[0004] In the prior art, there are dust-proof shielding covers with dust-proof nets provided on the surface of the shielding cover. However, the dust-proof mobile phone shielding covers in the prior art are generally not strong enough and are prone to rupture under stress, thereby affecting the normal use of components, circuits, assemblies, cables or the entire system in the mobile phone, and have certain limitations.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A dustproof mobile phone shielding cover includes a shielding cover body 1, a first fixed through-slot 3 and a second fixed through-slot 4 are respectively provided on both sides of the top of the shielding cover body 1, and a first dustproof net 5 and a second dustproof net 6 are respectively fixedly connected to the first fixed through-slot 3 and the second fixed through-slot 4. It should be noted that the first fixed through-slot 3 and the second fixed through-slot 4 in the utility model are appropriately changed according to the position of the internal components, circuits, assemblies, cables or the entire system of the mobile phone, because the first fixed through-slot 3 and the second fixed through-slot 4 are located in the components inside the mobile phone, and then the first fixed through-slot 3 and the second fixed through-slot 4 are respectively fixedly connected to the first dustproof net 5 and the second dustproof net 6. The first dustproof net 5 and the second dustproof net 6 are fixedly connected at the second fixed through groove 4, so that the entire shielding cover has dustproof properties, and the dustproof net is set here to facilitate the heat dissipation of components. A protruding block 7 is longitudinally arranged at the top center of the shielding cover main body 1, and an inner cavity is opened at the bottom of the shielding cover main body 1. A placement bin 10 is provided at the top of the inner cavity of the shielding cover main body 1 and corresponding to the protruding block 7. The interior of the placement bin 10 is provided with insulating rubber 11. The material of the protruding block 7 is the same as that of the shielding cover main body 1, and the material of the placement bin 10 is the same as that of the shielding cover main body 1.

[0023] Specifically, on the basis of the existing dustproof mobile phone shielding cover, a protruding block 7 is longitudinally arranged in the middle of the top of the shielding cover, and a placement bin 10 is arranged at the bottom of the protruding block 7 and at the top of the inner cavity of the shielding cover main body 1. An inner cavity is opened inside the placement bin 10, and an insulating rubber 11 is arranged in the inner cavity. The insulating rubber fills the inner cavity of the placement bin 10. When the shielding cover is subjected to force, if the object is large, because the protruding block 7 is more protruding than other parts of the shielding cover main body 1, the force will act on the protruding block 7, thereby providing a certain degree of buffering through the elasticity of the insulating rubber 11, thereby protecting the entire shielding cover main body.

[0024] Furthermore, longitudinal reinforcing ribs 8 are provided at a certain distance in the transverse direction along the front edge of the inner cavity top of the shielding cover body 1 , and the other end of the longitudinal reinforcing ribs 8 is located at the rear edge of the inner cavity top of the shielding cover body 1 .

[0025] Furthermore, a transverse reinforcing rib 9 is provided at a certain distance along the longitudinal direction on each side edge of the inner cavity top of the shielding cover body 1 , and the other end of the transverse reinforcing rib 9 is located at the other side edge of the inner cavity top of the shielding cover body 1 .

[0026] Specifically, considering that other objects may sometimes fall into other parts of the shielding cover body 1, these objects are relatively small, and in this case, they will be protected by several longitudinal reinforcing ribs 8 and transverse reinforcing ribs 9 at the bottom of the shielding cover body 1 to protect the shielding cover body 1.

[0027] Furthermore, a plurality of buckle grooves 2 are provided at the front and rear ends of the shielding cover body 1, and the shielding cover is fixed by the buckle grooves 2. This is an existing mature technology, and its internal specific structure and working principle will not be described in detail again.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
