[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, A screw connection with an EMC electromagnetic shielding housing, including a housing body 1, a protective housing 2 and a fixing component. The protective housing 2 is arranged inside the housing body 1. The fixing component includes a support frame 3, an elastic member, a push plate 4, a sliding plate 5 and a flange 6. The support frame 3 is arranged outside the lower side of the housing body 1. The support frame 3 is symmetrically arranged on the left and right sides of the support frame 3. The support frame 3 is provided with an activity groove with an opening on the side close to the housing body 1. The elastic member and the push plate 4 are arranged in the activity groove. The two ends of the elastic member are respectively connected with the push plate 4 and the inner wall of the activity groove. The lower side of the push plate 4 is connected with a sliding plate 5 that fits against the top wall of the fitting flange 6. The sliding plate 5 is in a cross shape. The left and right sides of the protective housing 2 are provided with connection grooves connected with the sliding plate 5. The left and right sides of the housing body 1 are provided with sliding holes adapted to the sliding plate 5.

[0023] During the actual use process, the protective housing 2 is inserted into the housing body 1. When the connection groove is aligned with the sliding hole, under the support of the support frame 3, the elastic member drives the push plate 4 to move, and the push plate 4 drives the sliding plate 5 to insert into the connection groove. It should be noted that when the sliding plate 5 is completely inserted into the connection groove, the front and rear side walls of the sliding plate 5 are in contact with the housing body 1, and the housing body 1 provides good support, and the protective housing 2 provides good electromagnetic protection.

[0024] During the actual use process, in order to facilitate unlocking the fixing component, the present utility model is improved in that the front and rear sides of the sliding plate 5 protrude from the front and rear side walls of the housing body 1, and through the front and rear side walls of the sliding plate 5, it is convenient to drive the push plate 4 to squeeze the elastic member.

[0025] In order to prevent the fixing component from causing the protective housing 2 to become loose and fall due to vibration, for this reason, a positioning bolt 7 is further arranged on the flange 6. The end of the positioning bolt 7 is in contact with the front and rear side walls of the sliding plate 5, and the positioning bolt 7 can stably resist the sliding plate 5 inserted into the connection groove to prevent the sliding plate 5 from becoming loose.

[0026] In this embodiment, the side of the sliding plate 5 close to the protective housing 2 is provided with a rounded corner to facilitate the sliding of the protective housing 2. The top wall of the housing body 1 is provided with a hollow hole to facilitate the auxiliary disassembly of the protective housing 2.

[0027] If only a spring 8 is used for the elastic member, it is easy to have an unstable support situation. For this reason, the elastic member includes a spring 8 and a telescopic rod 9. The spring 8 is sleeved on the telescopic rod 9. The two ends of the spring 8 and the telescopic rod 9 are respectively connected with the inner wall of the support frame 3 and the push plate 4. The telescopic rod 9 cooperates with the spring 8 to stably push the push plate 4 to do a linear motion.
