Abstract

The invention relates to a shielding cover. The shielding cover comprises a shielding rack and a shielding cover, wherein an edge part is arranged at an edge position of the shielding rack and outwards extends along a length direction, an edge position of the shielding cover is inwards bent along a length direction to form a bending groove, at least one concave structure is arranged on an upper surface of the shielding rack, at least one convex structure is arranged on a lower surface of the shielding cover and is adaptive to the concave structure, and the edge part is inserted into the bending groove from a groove opening of the bending groove until the convex structure is clamped into the concave structure. The shielding cover has the advantages that the die development cost and the die repair cost are reduced, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to electronic shielding technology, in particular to a shielding cover. Background technique [0002] The shielding cover generally includes a shielding bracket and a cover. In the prior art, the assembly of the shielding bracket and the cover adopts a hole and a convex hull structure. Therefore, it is necessary to form multiple convex hulls or hole features on the mold, and the forming punch is easy to wear And breakage, resulting in the risk of fuzz or plugging holes in the product holes after molding, as well as the shortness of the convex hull and the risk of rupture. In addition, the frequency of mold punch damage is high, increasing mold repair and reducing production efficiency. In addition, when electronic components need to be replaced or repaired, it is difficult to disassemble the existing shielding cover structure, and the shielding cover and electronic components on the PCB are easily damaged during disassembly, and ...
