Abstract
The utility model discloses a grounding spring, which possesses a horizontal long plate-shaped weld part. One end of the weld part is bended upward and then is inclinedly extended upward and inward to form a pressure stop portion, then is bended and extended outward to form a lower hook plate; the other end of the weld part is bended and extended upward, and then is extended horizontally to form an elastic portion; the free end of the elastic portion is bended and extended upward, and then bended downward to form a suppress portion; the free end of the suppress portion is extended outward, and then bended to the direction of the suppress portion and inclinedly extended to form an upper hook plate; and the free end of the upper hook plate is hooked in the lower hook plate. According to the utility model, the grounding spring is molded after a metal sheet with good conductivity is punched and bended, the structure is simple, the performance is good, and the production cost is low.
Description
Technical field
The utility model relates to a kind of shell fragment, particularly relates to a kind of simple in structurely, and performance is good, the grounding elastic part that production cost is low.
Background technology
Along with the progress and development of Information technology, electronic product is inseparable with our life, for example mobile communication product, computer or video and audio product etc., in our life in occupation of the status of not replacing.This electronic product constantly improves frequency of operation in order to improve the quality and function.Yet; The electromagnetic radiation pollution that high-frequency produced is seriously threatening the safety of flight safety, communication security and human body like aircraft too. in view of the above problems; Present most of manufacturer all adopts ground connection (Grounding), shielding (Shielding) and filtering methods such as (Filtering) to reduce amount of electromagnetic radiation, and wherein earthing mode has best protection effect.And on mobile phone products; Grounding elastic part is one of them important part; By means of the structure of precision and the conduction of good material; Between user and product, play the effect of the conducting of a high-quality, can effectively reduce the reflection of signal and, also be the optimal selection countermeasure of product being carried out electrostatic defending simultaneously the protection of EMI (electromagnetic interference).
But present grounding elastic part is owing to exist defective on the structure, and operator's device on each grounding elastic part has the interim compressing tablet that ends; Be used for the elastic portion of grounding elastic part is carried out spacing, prevent the extrusion together of grounding elastic part storehouse, after being installed in grounding elastic part on the product; To end compressing tablet more temporarily and take away,, increase production cost and human resources virtually though this kind method has been guaranteed the result of use of grounding elastic part to product; Reduce labor productivity, be unfavorable for market competition.The serious problems that also some grounding elastic part has ignored that its elastic portion is outwards pullled or overvoltage and causing reduces fatigue life of grounding elastic part.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure to the deficiency of above-mentioned prior art, and performance is good, the grounding elastic part that production cost is low.
For realizing above-mentioned purpose; The utility model provides a kind of grounding elastic part; It has the weld part of a horizontal long plate shape, and upwards sloping inwardly after weld part one end upwards bends extends to form only splenium, and the upper end of ending splenium extends to form down hook plate to the outer arcuate bending again; The weld part other end forms elastic portion to the direction horizontal-extending of weld part after upwards bending is extended again; The elastic portion free end more upwards bending be bent to form elastic pressing part downwards after extending, form hook plate to the direction bending and the diagonally extending of elastic pressing part again after the elastic pressing part free end stretches out, and upward the hook plate free end colludes and is held in down in the hook plate.
In sum, the utility model grounding elastic part is processed through the one-body molded pressing and bending afterwards of electric conductivity good metal sheet material, and simple in structure, performance is good, and production cost is low.

Fig. 2 is the front view of grounding elastic part shown in Figure 1.
The front view of Fig. 3 for being out of shape behind the grounding elastic part pressurized shown in Figure 1.
Each description of reference numerals is following among the figure:
Weld part 1 ends splenium 2

Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
See also Fig. 1 and Fig. 2, the utility model grounding elastic part structure that is formed in one is processed through pressing and bending by electric conductivity good metal sheet material; Simple in structure, performance is good, in present embodiment; Sheet metal be beryllium copper, phosphor bronze or stainless steel any one; Certainly, it also can be other electric conductivity good metal material, not to exceed.
See also Fig. 1 and Fig. 2, grounding elastic part comprises the weld part 1 of a horizontal long plate shape, and upwards sloping inwardly after an end of this weld part 1 upwards bends extends to form only splenium 2, and the upper end of ending splenium 2 extends to form down hook plate 3 to the outer arcuate bending again.Weld part 1 other end forms elastic portion 4 to the direction horizontal-extending of weld part 1 after upwards bending is extended again; The free end of elastic portion 4 upwards bending is bent to form elastic pressing part 5 downwards after extending again; Form hook plate 6 to bending of the direction of elastic pressing part 5 and diagonally extending again after the free end of elastic pressing part 5 stretches out, and on hook plate 6 free ends collude and be held in down in the hook plate 3.Weld part 1, end splenium 2, elastic portion 4 and elastic pressing part 5 and surround a cavity 7.The intersection of the bending part of elastic portion 4 and horizontal-extending part convexes with plate shoulder 41 to both sides.
See also Fig. 3, when the utility model grounding elastic part used, elastic pressing part 5 pressurizeds moved down; Drive elastic portion 4 distortion and be contained in downwards in the cavity 7, last hook plate 6 downwards and move inward, last hook plate 6 free ends are resisted against and end on the splenium 2 and following hook plate 3 outsides are resisted against hook plate 6 inboards; Be out of shape to cavity 7 inner bendings so that end splenium 2; Be resisted against inboard, elastic pressing part 5 tops until following hook plate 3 tops, promptly stop elastic pressing part 5 to continue to press down, thereby prevent that this grounding elastic part overvoltage from damaging.
In sum, the utility model grounding elastic part is processed through the one-body molded pressing and bending afterwards of electric conductivity good metal sheet material, and simple in structure, performance is good, and production cost is low.
