Abstract
The utility model relates to the technical field of a metal structure member and particularly relates to an electronic metal shrapnel. The electronic metal shrapnel comprises a W-type shrapnel body, wherein two ends of the shrapnel body are linear portions, a central portion has two symmetrical arc portions, and top ends of the linear portions have contact bars bending inwards. The electronic metal shrapnel has a simple structure, is convenient to manufacture, is not easy to deviate and has long service life, moreover, a surface of the metal shrapnel is coated with a nickel-plating layer, conductive performance of the metal shrapnel can be further improved, and resistor conduction efficiency is improved.
Description
Technical field
The utility model relates to hardware technical field, especially a kind of metal electron shell fragment.
Background technology
Metal clips (metal dome) is commonly called as the young sheet of pot.It adopts ultra-thin 0.05mm～0.1mm thickness, and the stainless steel material of Vickers hardness between 480～550 made.Metal clips have contact steadily, conduction is strong, resilience is stable, all good several large advantage of feel.Metal clips, because of its good conduction property, can play good switch and enable and control action between operator and product.Secondly metal clips possesses stable resilience force, can bring comfortable shake-up sense to operator.Meanwhile, metal clips has pressing the life-span of overlength.Metal clips is an important part on switch.Metal clips is mainly used in thin film switch, contact-making switch, pcb board, FPC plate, in the products such as medicine equipment.Metal clips of the prior art in long use procedure, the easily skew of occurrence positions, in addition, structure is comparatively complicated, is unfavorable for manufacturing.Given this, be necessary metal clips of the prior art to be improved, to address the above problem.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of simple in structure, the metal electron shell fragment that result of use is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of metal electron shell fragment, comprise " W " type elastic sheet body, described elastic sheet body two ends are line part, and centre has two symmetrical curved portions, and described line part top has aduncate bow strip.
Further, described elastic sheet body surface-coated nickel coating.
The beneficial effects of the utility model are that metal electron elastic piece structure of the present utility model is simple, easily manufactured, be not easy to be offset, long service life, in addition at metal clips surface-coated nickel coating, can enter the electric conductivity of a ground reinforcement metal shell fragment, improve resistance conducting efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. line parts in figure, 2. curved portions, 3. bow strip.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
Metal electron shell fragment as shown in Figure 1, comprises " W " type elastic sheet body, and elastic sheet body two ends are line part 1, and centre has two symmetrical curved portions 2, and line part 1 top has aduncate bow strip 4.Elastic sheet body surface-coated nickel coating, can enter the electric conductivity of a ground reinforcement metal shell fragment, improves resistance conducting efficiency.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
