Problems solved by technology

Among the various grounding methods, the grounding effect of the shrapnel is the best. In small equipment, due to space constraints and other reasons, the shape of the shrapnel is relatively small, especially the spring feet of the shrapnel are relatively small. In use, the small spring feet are relatively easy to deform. After deformation, there is no preload between the spring feet of the shrapnel and the metal parts that are in contact, resulting in grounding failure.
[0005] The application number is 200920261258.1, which discloses a grounding shrapnel between relatively moving metal parts in a mobile phone, including a shrapnel body. The shrapnel body is rectangular, and its long side direction is the direction of motion. Welding position, a slender gap is set in the middle position, the two ends of the gap are divided into the spot welding position, and raised contacts are symmetrically arranged on both sides of the gap, so as to solve the problem of relatively moving metal parts grounding and easy to connect the shrapnel The problem of reverse scraping and producing abnormal scratches
[0006] The current grounding shrapnel including the above-mentioned patents are usually installed in the form of screws or hot-melt welding, but due to the unreasonable structural design of the grounding shrapnel, its assembly and disassembly are relatively difficult
In the process of assembling the goods, due to structural defects, the accuracy of the assembly is not high; and the difficulty of the assembly process is relatively high, and the final product is unstable

Abstract

The invention relates to the technical field of grounding, relates to a grounding device, in particular to a grounding elastic sheet. The grounding elastic sheet comprises a U-shaped structure body, wherein an elastic sheet is arranged at one side of the body. The grounding elastic sheet is used for connecting a rear cover, namely a battery cover and a front shell to achieve grounding; and the grounding elastic sheet is simple in structure and low in manufacturing cost, and is convenient to install.

Description

technical field [0001] The invention relates to the technical field of grounding, and relates to a grounding device, in particular to a grounding elastic piece and a structure using the grounding elastic piece. Background technique [0002] Mobile devices, especially handheld electronic devices (such as mobile phones) have strict anti-static requirements to protect internal electronic components from static damage. Stable and reliable grounding meets anti-static requirements to protect electronic components. [0003] For example, the application number is 200410082448.9 discloses a grounding shrapnel, which is installed on an assembly with an installation hole. The ground elastic piece includes a bottom, an elastic part and a buckle part. The elastic part is connected to one side of the bottom, and the buckle part is connected to the other side of the bottom relative to the elastic part. When the grounding elastic piece is installed on the fitting, the elastic part and th...
