Embodiment Construction

[0014] refer to figure 1 As shown, the new type of shrapnel includes a bottom piece 1 with a longitudinal through hole inside to form a ring shape, two side pieces 2 and claws 5, the bottom piece 1 is provided with a ring-shaped groove 7 on the peripheral side, and the side pieces are evenly clamped in the ring groove 7; the lower part of the bottom plate is a downward convex part 3, and the upper part of the claw is inserted and connected in the through hole 4, and the lower part of the claw is provided with a barb 6 against the convex part.

[0015] The side panels are connected by an upwardly raised fastening section 9 and a straight section 8 below the fastening section. above the end of the segment. The fastening section 9 includes a starting section 91 inclined upward and a tail section 92 connected with the starting section and turned back downward. An angle of 15-30 degrees is formed between the initial section 91 and the straight section. The side pieces are copper...

Abstract

The invention discloses a novel elastic sheet. The novel elastic sheet comprises a bottom sheet, a plurality of side sheets and a clamping claw, wherein the bottom sheet is internally provided with a longitudinal through hole and is of an annular shape, an annular clamping groove is arranged at the peripheral side of the bottom sheet, the side sheets are uniformly clamped in the annular clamping groove, the lower part of the bottom sheet is a downward convex part, the upper part of the clamping claw is inserted into the through hole in a penetrating way, and the lower part of the clamping claw is provided with an inverted hook propping against the convex part. The novel elastic sheet is simple in structure, high in firmness and high in clamping performance, and unfavorable contact is difficult to occur.

Description

technical field [0001] The invention relates to a novel shrapnel. Background technique [0002] Shrapnel has a wide range of applications in electronic products. Although the structure is simple, it has absolutely critical functions. With the development trend of various electronic products being light, thin, fine, and sharp, shrapnel is required to have a design purpose. Usually, the shrapnel is formed by bending a metal sheet with good conductivity, and the metal sheet has elastic metal properties after bending, and is welded and fixed on the circuit board. [0003] The existing shrapnel has weak fixation and weak clamping performance, and is prone to poor contact. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new type of shrapnel with simple structure, strong fixation, strong clamping performance, and less prone to poor contact. [0005] In order to solve the above problems, the present invention adopts ...
