The bending angle of the side plate 12 is 90 degrees, and the bending angle of the flange 13 is 90 degrees. The number of the rims 13 can be plural depending on the actual design. The flange 13 is provided with a fixing hole 14. Through the fixing hole 14, the cover 1 is fixed to the circuit board by bolts.
One or several of the flanges 13 are provided with bending structures 15. The bending structure 15 includes a first bending edge 151 formed by bending and extending upwards and reversely from the tail end of the turning plate. A first plugging gap 2 is formed between the first bending edge 151 and the turning plate. The bending angle of the first bending edge 151 is greater than 90 degrees. The first plug-in slot 2 has a designed height dimension. The grounding spring plate 3 includes a base plate 31, a limiting plate 32 bent and extended from one end of the base plate 31, a first cantilever 33 bent and extended from the end of the limiting plate 32, and a second cantilever 34 bent and extended from the end of the first cantilever 33. The base plate 31 and the stopper plate 32 described above form a base body. The substrate 31 is defined to be horizontally arranged, and the limiting plate 32 is bent upwards by 90 degrees. The first cantilever 33 is bent towards the side facing away from the substrate 31, and an included angle between the first cantilever 33 and the limiting plate 32 is smaller than 90 degrees. The second cantilever 34 is bent upwards, and the included angle between the second cantilever 34 and the first cantilever 33 is larger than 90 degrees.
