The second straight portion 828 is bent toward a direction parallel to the main plate 400, one end of the second straight portion 828 is connected to the pressing portion 822, and the other end of the second straight portion 828 is connected to the second stopper 8442 of the second fixing portion 844.

The distance between the pressing portion 822 and the main board 400 may be slightly smaller than the height of the connector 600 and other components, and the distance between the first flat portion 826 and the main board 400 is greater than the distance between the pressing portion 822 and the main board 400 and is greater than the distance between the first fixing section 8424 and the main board 400. The distance between the second flat portion 828 and the main plate 400 is the same as the distance between the first flat portion 826 and the main plate 400.

When the first fixing section 8424 and the second fixing section 8444 are both fixedly connected to the middle frame 220, the first fixing section 8424 and the second fixing section 8444 can elastically deform and apply elastic force to the first straight portion 826, the second straight portion 828 and the pressing portion 822, wherein the pressing portion 822 is subjected to a large elastic force, the pressing portion presses the connector 600 under the elastic force, and when the pressing force is too large, the pressing portion 822 deforms in a direction away from the main board 400.

The embodiment of the present application can further compress the connector 600 by reducing the gap between the pressing plate main body 820 and the connector 600 by providing the form of the pull convex hull.

As shown in fig. 2 and 8, the electronic device in the embodiment of the above application further includes a reinforcing sheet 900, the reinforcing sheet 900 may be disposed to cover the slot 829, and the area of the reinforcing sheet 900 may be larger than the slot area of the slot 829, so that the reinforcing sheet 900 may close the slot 829. The reinforcing sheet 900 may be fixedly connected to the pressing plate main body 820, and may be welded or bonded, and the reinforcing sheet 900 may limit a deformation range of the pressing portion 822. It can be understood that when compressing portion 822 receives the reaction force of connector 600 and warp towards the direction of keeping away from mainboard 400, compressing portion 822 warp to the reinforcing sheet 900 of reaching the summit, then can't upwards warp again, and reinforcing sheet 900 can restrict the deformation scope of compressing portion 822, and the overall structure intensity of reinforcing clamp plate 800 also improves the spacing intensity to connector 600, prevents that connector 600 from taking off. In some implementations, the reinforcing sheet 900 may be integrally formed with the pressing plate 800, for example, the reinforcing sheet 900 and the pressing plate main body 820 may be formed as a complete plate, the reinforcing sheet 900 may include a bending portion 920 and a limiting portion 940, the bending portion 920 is bent toward a direction away from the main plate 400, and the limiting portion 940 is formed by bending the end of the bending portion 920 again toward a direction parallel to the main plate 400, the limiting portion 940 is stacked on the pressing plate main body 820 and covers the slot 829, and then the limiting portion 940 is fixedly connected to the pressing plate main body 820, so as to fix the reinforcing sheet 900. Of course, the bending portion 920 is fixedly connected with the pressing plate main body 820, and the limiting portion 940 is not fixedly connected with the pressing plate main body 820, for example, the limiting portion 940 can be abutted to the end face of the pressing plate main plate 820 in a manner of compacting the reinforcing sheet 900, so that the structural strength of the pressing plate 800 is further increased, and the pressing plate 800 is not easy to deform.
