Abstract

The utility model relates to an elastic sheet of an electric product. The elastic sheet is of a frame shape in appearance. The upper end portion of the frame and the lower end portion of the frame are used to contact with inner shells of the electric products. The middle of the frame concaves inwards and forms a concave portion, and therefore the elastic sheet is formed in a shape of the number '8'. Compared with an existing elastic sheet in a 'z' shape, the elastic sheet of the electric product has better pressure proof performance, is not easy to pile up in gold-plating machining to affect machining quality, and is not easy to clamp with other elements due to the fact that the elastic sheet of the electric product is in an enclosed ring shape when is in use.

Description

A kind of shell fragment of electronic product

Technical field

The utility model relates to a kind of shell fragment of electronic product

Background technology

A kind of parts that use through regular meeting on electronic product are exactly metal clips; Its end is welded on the circuit substrate; Other end elasticity conflict an electronic component or metal framework; Thereby make electronic component be electrically connected on circuit substrate, or the electrostatic defending to circuit substrate is provided.

In the prior art; The shell fragment of electronic product generally all is " Z " font; There is following shortcoming in this " Z " font shell fragment: 1) in the process of making shell fragment, one procedure is arranged, be placed in the electrolyte shell fragment gold-plated exactly; And a large amount of " Z " font shell fragments is easy to form the stacking phenomenon of " ZZZZ " in electrolyte, thereby can influence the crudy of shell fragment; 2) " Z " font shell fragment because self shape, therefore is easy to take place the phenomenon of blocking mutually with other elements in use; Withstand voltage degree when 3) in addition, " Z " font shell fragment uses is not high yet

Summary of the invention

the utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of improved shell fragment that is used for electronic product is provided.

For solving above technical problem, the utility model is taked following technical scheme:

The shell fragment of a kind of electronic product is frame shaped, and the upper end of this framework and bottom are used for contacting with the inner casing of electronic product; The middle part of framework caves inward, and forms concave shaped portion.

preferably, the ratio of width between the said concave shaped portion and framework width is between 0.6 ~ 0.8:1.

preferably, the middle part of the said framework camber that caves inward.

preferably have opening in the middle of the bottom of said framework.

preferably, both sides, the cross section spirogyrate camber of said framework.

preferably, the material of said shell fragment is a beryllium copper.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

the utility model shell fragment middle part caves inward, and forms the shape of similar " 8 " word, compares with existing " Z " font shell fragment, and the utility model shell fragment has better voltage endurance capability; Shell fragment also is difficult for producing the stacking phenomenon when gold-plated, and crudy is improved; And when using, shell fragment, therefore also is difficult for blocking mutually with other elements owing to be the ring-type of sealing.

Description of drawings

Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further detailed explanation:

Fig. 1 is the front view of the utility model shell fragment;

Fig. 2 is the cross-sectional view of the utility model shell fragment;

wherein: 1, framework; 2, upper end; 3, bottom; 30, opening; 4, concave shaped portion.

Embodiment

Embodiment 1

present embodiment is used for the shell fragment of electronic product, selects for use beryllium copper to process, and it has framework 1, and the upper end 2 and the bottom 3 of framework 1 are used for contacting with the inner casing of electronic product; The middle part of framework 1 camber that caves inward forms concave shaped portion 4.This makes the present embodiment shell fragment have the profile of similar " 8 " word.

In the present embodiment, the width w between the concave shaped portion 4 ₁ Width w with framework 1 ₂ Ratio be 0.75:1.

Have opening 30 in the middle of the bottom 3 of framework 1, this is the bending machining of being convenient to shell fragment on the one hand; On the other hand, when shell fragment was welded on the electronic product, opening 30 can play the effect in tin hole, can guide flowing of scolding tin, made the shell fragment welding fixing better.

in addition, both sides, the cross section spirogyrate camber of framework 1.

The withstand voltage degree of present embodiment shell fragment significantly improves, and compression resistance can reach more than the 5kg, and the compression resistance of common " Z " shape shell fragment is generally about 2kg.

After present embodiment shell fragment is welded on the electronic unit such as mainboard, be the ring-type of sealing, be difficult for blocking mutually with miscellaneous part.

More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection range of the utility model
