Problems solved by technology

During the crimping process of the antenna, the rear cover may be pushed, and when the elastic piece is pulled in the opposite direction, the oblique pulling force applied by the antenna feed point to the contact part is very likely to cause the elasticity Mechanical deformation of the arm damages the shrapnel
And because the size of the shrapnel is very small, when the mobile phone vibrates or falls, the antenna feed point may also cause mechanical deformation of the shrapnel
[0004] Patent Application No. 201420071013.3 of the People's Republic of China discloses an elastic piece for connecting the antenna. The elastic arm includes a horizontal part extending parallelly from the tensioning part, and the plate-shaped base extends upward from both sides and overlaps the The retaining portion on the horizontal portion, but the retaining portion is located at the tail of the elastic arm, resulting in the defect that the moment arm is longer, and a slightly larger external force may also cause damage to the elastic arm

Embodiment Construction

[0021] see Figure 1 to Figure 6 As shown, the antenna connection elastic piece of the present invention includes a plate-shaped base 10, a tensioning portion 20 formed by reversely bending and extending from the rear end of the plate-shaped base 10, and an elastic arm formed by extending obliquely upward from the end of the tensioning portion 20. 30 , and a support portion 40 formed by bending backwards from the end of the elastic arm 30 and extending toward the plate-like base 10 . One end of the tightening part 20 is defined as the rear end, and the opposite side is the front end.

[0022] An upwardly recessed tin container 11 is formed between the plate base 10 and the tensioning portion 20 . The elastic arm 30 includes a horizontal portion 31 extending from the end of the tensioning portion 20 parallel to the plate-shaped base 10, an inclined portion 32 extending upward from the end of the horizontal portion 31, and an inclined portion 32 formed on the inclined portion. ...

Abstract

An antenna connection elastic sheet comprises a plate base, a tensioning portion formed by reverse bending extension from the rear end of the plate base, an elastic arm formed by the inclined upward extending of the tail end of the tensioning portion and a supporting portion formed by reverse bending extending from the tail end of the elastic arm towards the plate base. Two sides of the lower end of the supporting portion extend towards the transverse direction to form retaining arms, the two cross sides of the plate base at the positions of the retaining arms are bent upwards to extend to form retaining sheets above the retaining arms, and the retaining arms comprise upper retaining sheets and front retaining sheets. The upper retaining sheets are formed by upward bending extending from the two sides of the plate base and bending extending towards the retaining arms, and the front retaining sheets are formed by downward bending extending from the front ends of the upper retaining sheets. The antenna connection elastic sheet is good in service life and not easy to damage.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an antenna connecting shrapnel used for connecting an antenna and a printed circuit board in a mobile phone. Background technique [0002] At present, smart phones are developing in the direction of larger screen size and thinner and thinner. The mobile phone antenna is generally installed on the back cover of the mobile phone. Some mobile phones with metal frames also use the metal frame directly as an antenna. The antenna is usually connected to the motherboard. A feed point, the feed point needs to be connected to the main board through a connecting device. [0003] Usually, the antenna connection elastic piece generally includes a plate-shaped base, a tensioning portion bent and extended from one end of the plate-shaped base, and an elastic arm and a contact portion formed obliquely upwards from the tensioning portion. During the crimping process of the antenna, the rear...
