Surface mounting elastic sheet with supporting section and blocking adsorption section

Abstract

The invention relates to a surface mounting elastic sheet with a supporting section and a blocking adsorption section. The surface mounting elastic sheet comprises a mounting section, an elastic reflexed section, an auxiliary section, an elastic arm section, the supporting section and the blocking adsorption section. The elastic arm section is limited to deformation amplitude by the blocking adsorption section when in hook junction or being dragged by external objects; and the blocking adsorption section disperses the lower pressure to the supporting section when in normal use, so that the cushioning effect is strengthened and the using efficiency of the elastic sheet is maintained.

Description

【Technical field】 [0001] The technical field of the present invention relates to a surface-mounted shrapnel, especially a surface-mounted shrapnel with a supporting section and a blocking adsorption section. 【Background technique】 [0002] Shrapnel has a wide range of applications in the electronics industry, such as for battery electrical connection, antenna electrical connection, anti-electromagnetic interference grounding, heat conduction, or buffering.... A common shrapnel structure such as figure 1 As shown, it is made by bending an extremely thin copper sheet, and has a mounting section 2, an elastic reflex section 3, an elastic arm section 5, and an absorbing portion 57 extending from the elastic arm section 5 and parallel to the installation section. [0003] The function of the mounting section 2 is to weld the elastic piece 1 on the circuit board 90 by using surface mount technology, that is, when the elastic piece 1 is correspondingly placed on the circuit board ...

Problems solved by technology

However, the end of the elastic arm section 5 with the adsorption portion 57 is spaced from the installation section 2 without any obstruction, so that the elastic pieces 1 are easily hooked to each other during assembly and transportation. Furthermore, except that the elastic pieces 1 are hooked to each other In addition, it is also easy to be hooked by foreign objects so that the elastic arm section 5 is reversely bent to reduce the use function, or cause the elastic piece 1 to deform and lose its effectiveness, or even break and become unusable

[0006] Also, the elastic arm section 5 is too thin, and when it is subjected to excessive downward force, the elastic reflex section 3 will be temporarily deformed, and as the force is greater, it will exceed the linear range of Hooke's law, which will lead to The elastic arm section 5 and the elastic reflex section 3 produce irreversible plastic deformation, and even the elastic piece 1 breaks due to the stress concentration effect

[0007] In addition, since the suction part 57 for the suction nozzle is arranged on the top of the elastic arm section 5, once the shape of the elastic piece 1 has a workmanship error, when the suction nozzle moves down to suck, it is likely to squeeze the elastic arm section 5 due to the downward movement, causing the elastic piece 1 It directly bounces away, causing additional foreign matter to appear on the circuit board 90, so the operation process must be interrupted, and the shrapnel 1 is taken out manually
