Problems solved by technology

[0005] However, in such a structure, although the protruding part 130 prevents it from falling off, if the elastic part 110 lifts up and deforms in the direction of the arrow B, the protruding part 130 will easily break away from the mounting hole 14 and the grounding spring 100 will fall off.

Embodiment Construction

[0019] image 3 A perspective view of an assembly for installing a metal casing for the grounding shrapnel of the present invention. Fig. 4 is a perspective view of the structure of the grounding shrapnel of the present invention. The metal dome 200 includes an elastic portion 210 , a bottom 220 and an engaging portion 240 . The elastic portion 210 is connected to one side of the bottom 220 and generally extends toward a first direction L, and the engaging portion 240 is connected to the other side of the bottom 220 . The elastic portion 210 , the bottom portion 220 and the engaging portion 240 are integrally formed. In this embodiment, the engaging portion 240 and the bottom 220 form a U-shape. In addition, the ground spring 200 further includes a protruding portion 230 , the protruding portion 230 has an inclined surface 232 and an opening 234 adjacent to the inclined surface 232 and the bottom 220 , and the direction of the opening 234 is perpendicular to the first direc...

Abstract

The invention is a grounding elastic plate, installed on an assembly part with a mounting hole, comprising a base, an elastic part and a fastening part, where the elastic part is connected to one side of the base and the fastening part is connected to the other side of the base. As the grounding elastic plate is mounted on the assembly part, both the elastic part and fastening part coat the edges of the assembly part.

Description

technical field [0001] The invention relates to a grounding shrapnel used in an electronic device. Background technique [0002] Generally speaking, in an electronic device, the grounding of the circuit board is usually to electrically connect a certain part of the circuit board to the metal casing of the electronic device, and the electrical connection is usually accomplished through a metal elastic piece. Such as figure 1 As shown, a prior art ground shrapnel 100 is installed on a metal casing 10 of an electronic device, and the metal casing 10 is provided with a fitting 12 extending from the side wall of the metal casing 10 and has a mounting hole 14 , for installing the grounding shrapnel 100, and the circuit board (not shown) is placed on the top of the grounding shrapnel 100, so that the circuit board and the metal casing 10 are electrically connected through the grounding shrapnel 100, which completes the grounding of the circuit board. [0003] The structure of the...
