Specifically, the grounding spring sheet 10 includes a base portion 11, a first arch portion 12 and a second arch portion 13 provided on the base portion 11. The first arch 12 is used for abutting against the structural member, and the second arch 13 is used for abutting against the metal ground, so that the structural member can be grounded through the grounding spring plate 10.

The first arch 12 is provided in the first portion 110, and is arched from the first portion 110 to a side away from the second portion 112. The second arch portion 13 is provided in the second portion 112, and is arched from the second portion 112 to a side away from the first portion 110.

As can be seen from the above description, the first arch portion 12 is disposed on the first portion 110 and arches in a direction away from the second portion 112, the second arch portion 13 is disposed on the second portion 112 and arches in a direction away from the first portion 110, and the first portion 110 and the second portion 112 are disposed opposite to each other, so that the grounding spring 10 can achieve large-span grounding in the arrangement direction of the first portion 110 and the second portion 112, and the grounding difficulty of the structural member in the mobile terminal is reduced.

In one embodiment, the first portion 110 is disposed parallel to the second portion 112, and the intermediate portion 114 is connected to the same side of the first portion 110 as the second portion 112. For example, the first portion 110, the second portion 112, and the intermediate portion 114 are in a "[" configuration. So configured, a uniform gap 111 may be formed between the first portion 110 and the second portion 112, and on the one hand, portions of components within the mobile terminal may be disposed within the gap 111 to increase space utilization; on the other hand, the parallel arrangement of the first portion 110 and the second portion 112 is also advantageous for saving the internal space of the mobile terminal. Of course, in other embodiments, the middle portion 114 may be connected to different sides of the first portion 110 and the second portion 112, that is, the first portion 110, the second portion 112 and the middle portion 114 may have a "Z" shape.

In one embodiment, the middle portion 114 is configured in a straight configuration, and the middle portion 114 may be perpendicular to the first portion 110. The intermediate portion 114 is perpendicularly joined to the second portion 112. By such arrangement, a uniform gap can be formed between the first portion 110 and the second portion 112, the space surrounded by the middle portion 114, the first portion 110 and the second portion 112 can be fully utilized, and the space occupied by the middle portion 114 is small.

It should be noted that the junction between the middle portion 114 and the first portion 110 may be rounded, and the junction between the middle portion 114 and the second portion 112 may be rounded, so as to avoid stress concentration.

With continued reference to fig. 1, in one embodiment, one end of the first arch 12 is connected to the first portion 110, and the other end of the first arch 12 is a free end i 120. So configured, the first arch portion 12 can withstand proper deformation at the time of abutment to increase the abutment force, and can compensate for the machining error by the deformation amount, thereby reducing the machining accuracy. One end of the second arch 13 is connected to the second portion 112, and the other end of the second arch 13 is a free end ii 130. The technical effects brought by the arrangement of the second arch portion 13 are the same as those of the first arch portion 12, and will not be described here again.

The first arch portion 12 may be provided in a circular arc structure, and an arc surface of the circular arc structure is used for abutting against a structural member, and the circular arc surface is smoother and has no sharp corner, so that an indentation caused to the structural member can be avoided. The second arch part 13 may be provided in a circular arc structure with a circular arc surface for abutting against the metal ground, the circular arc surface being smooth and free of sharp corners, so that the impression of the metal ground can be avoided. In the embodiment shown in fig. 1, the starting end of the first arch 12 extends from the first portion 110 to a side away from the second portion 112, the free end i 120 of the first arch 12 extends around to a side close to the second portion 112, the starting end is in arc transition connection with the free end i 120, and the arc surface is used for abutting against a structural member. The structure of the second arching portion 13 may be provided with reference to the first arching portion 12, but is not limited thereto.

In one embodiment, the second portion 112 is formed with a second through hole 1120, one end of the second arch 13 is connected to the edge of the second through hole 1120, the other end of the second arch 13 is a free end ii 130, and the free end ii 130 faces the second through hole 1120. In this way, the connection area between the second arch portion 13 and the second portion 112 is reduced, and the elastic deformation amount of the second arch portion 13 is increased, so that the grounding distance range that the grounding spring sheet 10 can adapt to is increased, and the compatibility is better.
