[0002] A shielding cover is a device used to shield the electronic signals of components. In actual application scenarios, there is also a need for mutual isolation between multiple components covered by the shielding cover. Therefore, some shielding covers are provided with isolation members in the cover body, such as Figure 1 As shown, in the existing shielding cover, the isolation member 2 is generally welded to the cover body 1 by welding. When assembling the isolation member and the cover body, not only welding equipment is required, but also a jig for positioning the isolation member is needed, which is rather troublesome to operate. In other words, the existing shielding cover with an isolation member has the problems of cumbersome assembly procedures and low assembly efficiency. Summary of the Utility Model

[0029] Embodiment 1

[0030] Please refer to Figures 2 to 4, Embodiment 1 of the present utility model is: A shielding cover, including a cover body 1 and a separator 2. The cover body 1 and the separator 2 are respectively made of metal materials with electromagnetic shielding performance. An installation window 11 is provided on the cover body 1, and the separator 2 is inserted at the installation window 11. The separator 2 includes a first arm 21 and a second arm 22. The first arm 21 and the second arm 22 are connected to form a V-shaped structure. The ends of the first arm 21 and the second arm 22 away from each other respectively have a clamping plate 23 extending outward. Clamping blocks 24 are respectively provided on the sides of the first arm 21 and the second arm 22 away from each other. A clamping space 25 for clamping the edge of the installation window 11 is formed between the clamping block 24 and the clamping plate 23.

[0031] Before the separator 2 is assembled to the cover body 1, in the separator 2, the first arm 21 and the clamping plate 23 connected to it form an obtuse angle structure, and the second arm 22 and the clamping plate 23 connected to it form an obtuse angle structure.

[0032] The cover body 1 includes a top plate 12 and a surrounding wall 13 connected to each other. The surrounding wall 13 is arranged along the edge of the top plate 12, and the installation window 11 is provided on the top plate 12.

[0033] To facilitate the positioning and installation of the separator 2, a receiving groove 14 is provided on the top surface of the top plate 12, and at least part of the area of the clamping plate 23 is received in the receiving groove 14.

[0034] To avoid the clamping plate 23 causing an increase in the overall thickness of the shielding cover, preferably, the top surface of the clamping plate 23 is arranged lower than or flush with the top surface of the top plate 12. Of course, in some application scenarios, it is also acceptable that the top surface of the clamping plate 23 is higher than the top surface of the top plate 12.

[0035] As a preferred implementation manner, the receiving groove 14 is a stamping structure formed by stamping, which can facilitate the processing and forming of the receiving groove 14. In other embodiments, it is also possible to process the receiving groove 14 by milling.

[0036] The separator 2 is an integral structure processed from a single metal plate. Such a separator 2 has good integrity and low manufacturing cost.

[0037] To enable the spacer 2 to be inserted into the installation window 11 more smoothly, optionally, the clamping block 24 has a guiding surface 26, the guiding surface 26 is arranged away from the clamping plate 23, the guiding surface 26 is an arc surface or an inclined surface, and after the guiding surface 26 contacts the edge of the installation window 11, it can guide the first arm 21 and the second arm 22 to deform towards each other, so that the clamping block 24 can smoothly pass through the installation window 11. In other embodiments, it is also possible not to provide the guiding surface 26 on the clamping block 24. At this time, the assembler can manually control the first arm 21 and the second arm 22 to approach each other, so that the clamping block 24 passes through the installation window 11.

[0038] In this embodiment, the clamping block 24 is a convex structure formed by stamping. This can not only facilitate the forming of the clamping block 24, but also reduce the consumables required for manufacturing the spacer 2, thereby saving the production raw material cost of the shielding cover.

[0039] To make the force on the spacer 2 more balanced, preferably, the clamping block 24 on the first arm 21 and the clamping block 24 on the second arm 22 are arranged opposite to each other. In an actual product, it is also possible that the clamping block 24 on the first arm and the clamping block 24 on the second arm 22 are arranged in a staggered manner.

[0040] The number of the clamping blocks 24 on the first arm 21 is multiple, and / or the number of the clamping blocks 24 on the second arm 22 is multiple. In this embodiment, two clamping blocks 24 are respectively provided on the first arm 21 and the second arm 22.

[0041] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
