Abstract

A structure of an elastic sheet is formed by a stand body and an elastic component. The stand body has a plane fixed portion. Two sides of the fixed portion extend in a linear manner to form shielding portions, and each shielding portion is provided with a spacing hole. Moreover, the elastic component includes an elastic arm and a contact portion. The fixed portion is folded upward and extends in a reverse manner to form the elastic arm. The elastic arm extends upward to form the contact portion which is arc-shaped. The contact portion is further equipped with an opening which corresponds to the elastic arm to make the contact portion exhibit good elastic intensity when force is acted on the contact portion, thereby providing buffer and shock-absorbing effects. In addition, link lugs facing to the spacing holes are adopted to make the elastic arm exhibit an effect of movable spacing, thereby preventing the elastic sheet against deformation and damage, and improving the service life of the elastic sheet.

Description

Elastic piece structure

Technical field

The utility model relates to a kind of shell fragment, especially refers to provide the effect of a buffering with shock-absorbing, and prevents the deformed damaged gain elastic piece structure in useful life.

Background technology

Press, along with the progress and development of Information of Science and Technology, such as mobile communication product, computer or video and audio product etc. of electronic product, in our life in occupation of the status of not replacing.As is generally known, nearly all electronic product all can produce electromagnetic interference (Electromagnetic Interference in operation, EMI) problem, and after electromagnetic interference namely refers to electric product itself energising, the electromagnetic wave that produces because of electromagnetic induction effect to arround the interference effect that causes of electronic equipment, also because electromagnetic interference can cause other electric equipment work interruptions, undesired shutdown, safeguards increase, crosstalk and system delay, and the injury etc. that causes human body.

In view of the above problems, present most of manufacturer all adopts the methods such as ground connection (Grounding), shade (Shielding) and filtering (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 to the protection of EMI (electromagnetic interference), also be the optimal selection countermeasure of product being carried out electrostatic defending simultaneously.

Only, known grounding elastic part is owing to existing defective on the structure, and general shell fragment design is simple and easy, majority is the force-applied shell fragment of one-part form, excessive or press to fall into when excessive when pressure, the bent angle of shell fragment can suffer damage because material is tired, causes shell fragment to lose originally due elasticity.And, excessive pressure and excessive compression.Also some grounding elastic part has been ignored its elastic portion and is pulled outwardly and pulls or serious problems that overvoltage and causing reduces fatigue life of grounding elastic part.

Summary of the invention

The technical problem that the utility model solves is namely providing a kind of elastic piece structure, and the effect of buffering with shock-absorbing can be provided, and prevents that deformed damaged from gaining useful life.

The technological means that the utility model adopts is as follows.

A kind of elastic piece structure includes at least: a pedestal, and it has a fixed part that is the plane, and this fixed part both sides straight line extends to form an occlusion part, and this occlusion part is provided with a spacing hole; One elastic component, it has an elastic arm and an arc-shaped contact part, and this elastic arm is made of bending fold back extension on other side direction of relative two occlusion parts of fixed part, and contact site upwards is camber extension by elastic arm and consists of, and this contact site has an opening, and this opening is relatively this elastic arm, and relative this spacing hole of elastic arm two sides is respectively established a pivot ear in addition.

This resilient-arm position height is not higher than this spacing hole relative position height.

This elastic arm generally is parallel with this fixed part.

This fixed part is provided with at least one perforation.

The beneficial effect that the utility model produces is: at first, have better elastic strength by elastic arm when contact site is stressed, and reach the effect of buffering and shock-absorbing.

Secondly, elastic arm two sides are respectively established a pivot ear, and this pivot ear relative limit hole site, in order to do making the elastic arm activity have position-limiting action, and prevent that deformed damaged is with gain useful life.

Embodiment

The utility model " elastic piece structure " basic structure as shown in Figures 1 and 2, shell fragment is made of a pedestal 10 and an elastic component 20.

Wherein: this pedestal 10 has a fixed part 11 that is the plane, and these fixed part 11 both sides straight lines extend to form an occlusion part 12, and this occlusion part 12 is provided with a spacing hole 121.

This elastic component 20 has an elastic arm 21 and an arc-shaped contact part 22, and this elastic arm 21 is made of bending fold back extension on relative two occlusion parts of fixed part 12 other side direction, and contact site 22 upwards is camber extension by elastic arm 21 and consists of, and this contact site 22 has an opening 221, and this opening 221 is relatively this elastic arm 21, can prevent that contact site 22 from colluding foreign object and being subjected to external force and damaging, in addition elastic arm 21 2 sides relatively this spacing hole 121 respectively establish a pivot ear 211.

During whole the use, as shown in Figure 3, this fixed part 11 is provided with at least one perforation 111, allow scolding tin adhere to and fix with an electronics group assembly (not shown) by perforation 111, and the extended spot that can avoid scolding tin to seek connections with this this fixed part 11 and elastic arm 21 causes reducing elasticity, this contact site 22 is used for and another electronics group assembly its contact position of (not shown) or corresponding formation electrical contact in addition, and this elastic arm 21 generally is parallel with this fixed part 11, and these elastic arm 21 position height are not higher than this spacing hole 121 relative position height.

When contact site 22 is stressed, as shown in Figure 4, these elastic arm 21 pressurizeds move toward fixed part 11, more can be by the reciprocal restoring force of elastic arm 21 towards fixed part 11, the effect of one buffering with shock-absorbing can be provided, and further by 121 positions, pivot ear 211 relative limit holes, start has position-limiting action and make elastic arm 21 have up and down, and can reduce elastic arm 21 and meet with stresses, gain useful life to prevent deformed damaged.
