Embodiment Construction

[0017] see figure 2 , image 3 As shown, the elastic sheet 20 of the present application includes a plate-shaped base 21, a tensioning portion 22 formed by reverse bending from one end of the plate-shaped base 21, an elastic arm 23 extending from the end of the tensioning portion 22, formed on the The contact portion 24 on the elastic arm 23, the support arm 25 formed by bending from the end of the elastic arm 23 toward the plate base 21 and extending obliquely toward the tensioning portion 22, and the support arm 25 formed from the end of the support arm 25 The support portion 26 is formed by bending upwards. The elastic arm 23 includes a horizontal portion 231 extending from the end of the tensioning portion 22 parallel to the plate-shaped base portion 21, and an inclined portion 232 extending obliquely upward from the end of the horizontal portion 231. The contact portion 24 is a spherical structure formed by punching upward from the inclined portion 232 .

Abstract

An elastic sheet is disclosed and comprises a plate-shaped base part, a tensioning part which is bent from one end of the plate-shaped base part in a reverse direction, an elastic arm which extends from the tail end of the tensioning part, a contact part formed on the elastic arm, a support arm which is bent toward the plate-shaped base part from the tail end of the elastic arm and extends toward the tensioning part in an inclined manner, and a support part which is bent upward from the tail end of the support arm; by bending one end, positioned close to the support part, of the support arm toward the elastic arm, an infolding part is formed; via the infolding part, the support arm and the plate-shaped base part are always in a suspended state when the support arm is pressed downward.

Description

technical field [0001] The present application relates to the field of electrical connectors, in particular to a shrapnel for antenna connection. Background technique [0002] At present, thinning has become the main development trend of smart phones, and the problem brought about by the thinning of mobile phones is that mobile phone components need to be ultra-thin at the same time. Smartphones generally require a number of elastic pieces for connecting to the antenna on the mobile phone casing, but the elasticity of the elastic pieces will be affected after the thinning of the elastic pieces. [0003] Such as figure 1 As shown, the existing elastic sheet 10 includes a plate-shaped base 11, a tensioning portion 12 formed by reverse bending from one end of the base 11, an elastic arm 13 formed by extending upward from the tensioning portion 12, and formed on the The contact portion 14 at the upper end of the elastic arm 13, the supporting arm 15 is formed by extending in p...
