Abstract
The utility model discloses a terminal spring sheet of a laminated structure. The terminal spring sheet comprises a spring sheet body, wherein a base body of the spring sheet body is a stainless steel sheet, and a copper layer and a tin layer are plated on the surface of the stainless steel sheet sequentially from inside to outside. The terminal spring sheet has the advantages of being good in spring sheet elasticity, excellent in electrical conductivity and resistant to corrosion.
Description
Technical field
The utility model relates to the binding post technical field, especially relates to a kind of terminal springs sheet.
Background technology
The binding post connection of lead is for ease used; Mainly form by one section sheet metal that is enclosed in the ambroin the inside; These ambroin two ends are all porose can insert lead, thereby binding post can couple together lead, and can break off at any time; And needn't weld them or be intertwined, easily quick.
The inner sheet metal of existing binding post is processed by materials such as steel or copper, and its weak point is: steel sheet metal corrosion resistance and conductivity are relatively poor, and the conductivity of copper sheet metal is better; But strain property is relatively poor; Lost efficacy easily through plugging repeatedly behind the lead, and the surface of copper can be oxidized to verdigris, the conductivity of verdigris is very poor; Influence the performance of terminal, therefore be necessary to improve.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of terminal springs sheet of laminated construction, and it has good springiness, good, the corrosion resistant characteristics of conductivity.
To achieve these goals, the technical scheme that the utility model adopted is: the terminal springs sheet of laminated construction, comprise the spring leaf body, and the matrix of said spring leaf body is a stainless steel substrates, the stainless steel substrates surface is coated with copper layer and tin layer from the inside to the outside successively.
After adopting said structure, the utility model is compared the advantage that is had with prior art and is: good springiness, conductivity are good, corrosion-resistant.The matrix of the terminal springs sheet of the laminated construction of the utility model is a stainless steel substrates, thereby has better elasticity, after plugging lead repeatedly, is difficult for losing efficacy because of distortion.Be coated with copper layer, tin layer outside the stainless steel layer.Because copper, tin are the optimum conductor of electricity, guaranteed to have good electrical contact property between spring leaf and the lead, and the tin layer of outermost can prevent that copper is oxidized.Simultaneously, the tin layer is difficult for being scratched by lead, and combines between copper and the tin closely to have strengthened the adhesion of coating.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified
Fig. 1 is the binding post overall structure sketch map of the utility model.
Fig. 2 is the structural representation of the terminal of the utility model.
Fig. 3 is that the master of the embodiment of the utility model looks the sectional structure sketch map.
Among the figure: 1, pedestal; 2, terminal, 21, the terminal frame, 22, the spring leaf body, 221, stainless steel substrates, 222, the copper layer, 223, the tin layer, 23, V-notch, 24, breach.
Embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection range of the utility model.
Embodiment, see that Fig. 1 is to shown in Figure 3: binding post comprises that terminal 2 and 1, two terminal 2 of pedestal place respectively in two terminal accommodating nests on the pedestal 1, and terminal 2 is made up of terminal frame 21 and spring leaf body 22.Wherein, shaped as frame terminal frame 21 can be processed by stainless steel, and spring leaf body 22 is S-shaped and be stuck in the terminal frame 21.Form V-notch 23 on the spring leaf body 22 and be used to the lead of pegging graft with breach 24.The matrix of spring leaf body 22 is a stainless steel substrates 221, and stainless steel substrates 221 surfaces are coated with copper layer 222 and tin layer 223 from the inside to the outside successively, thereby guarantees that spring leaf 22 has better elastic, lead property, corrosion resistance, and long service life.
