Embodiment Construction

[0033] The invention can be used to electrically connect a substrate and other matching components, and can be used for electromagnetic protection. The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with accompanying drawings. And for the sake of explanation, in addition to the installation section of the following shrapnel for welding to the circuit board, various complex deformations above the installation section are called elastic arm sections. As for the differences between the elastic arm sections of various shrapnel, in this The inventions are not listed one by one.

[0034] Please refer to image 3 , 4 The shrapnel 2 shown is made by bending a copper sheet, and is soldered to the substrate 1 by the surface adhesion method, and the conductive material of the shrapnel 2 itself is used for electrical connection; it includes a section of in...

Abstract

The invention relates to a surface mounting metal elastic sheet with a bending enhancement part on an elastic arm, which comprises a mounting section for being welded on a substrate and an elastic arm section, wherein the elastic arm section extends from one end of the mounting section and comprises at least one bending enhancement part, and the bending enhancement part can reduce the deformation amount of the most fragile part when the elastic arm section deforms under stress and can disperse the stress to other parts. Thus, the service life of the elastic sheet with the bending enhancement part is prolonged, and moreover, the elastic sheet structure can be maintained to achieve an expected elasticity performance.

Description

【Technical field】 [0001] The technical field of the present invention relates to a surface-mounted elastic piece, in particular to a surface-mounted metal elastic piece with a bending reinforcement part on the elastic arm. 【Background technique】 [0002] The shrapnel commonly used in the electronics industry is made of a metal, such as beryllium copper, phosphor bronze, etc. The elastic force after folding is used as a connection for grounding, buffering or electromagnetic protection (EMI, electro-magnetic interference) when other components are electrically connected to the substrate, or for electrical connection of batteries, electrical connections of antennas, Anti-electromagnetic interference grounding...etc. A kind of structure of known shrapnel 6 is as figure 1 As shown, it is made by bending a thin copper sheet, has a section of mounting section 61, a section of spring arm section 62, and an adsorption part 63 that is farther from the spring arm section 62 from the ...
