The square pin comprises a square steel pin, four side surfaces of the central section of the square steel pin are respectively provided with a triangle projection, a vertex angle of each triangle projection is round, two ends of the square steel pin are cone-shaped, tips of cones of the two ends are round, and the surface of the square steel pin is a copper layer. The square pin is simple and stable in structure, low in cost and easy to use, service lifetime of products can be ensured, and production efficiency can be improved.

Description

Four directions pin

Technical field

The utility model relates to electronics contact pin, is specifically related to a kind of cubic pin.

Background technology

Four directions pin is a kind of widely used electronics contact pin, and existing cubic pin is generally fine copper structure, at medium position, a stuck point is set., there is following shortcoming in the cubic pin of this structure: (1) production cost is high; (2) quality weight, cost of transportation is high; (3) when in use, often there will be loosening situation, so that affect the stable connection of cubic pin and binding post, reduce life of product; (4) termination out-of-shape, affects production efficiency during use, increased the cost of enterprise.

Summary of the invention

The purpose of this utility model is to provide a kind of cubic pin.

The utility model is achieved through the following technical solutions:

A kind of cubic pin, comprise cubic draw point, four sides of the medium position of described cubic draw point, be respectively arranged with a leg-of-mutton projection, the drift angle of described triangular hill is fillet, the two ends of described cubic draw point are conical, and the conical termination at described two ends is fillet, and described cubic draw point surface is copper layer.

Further, described cubic draw point and four projections are structure as a whole.

The utility model replaces the contact pin of traditional fine copper, the steel of outer field copper and internal layer, consists of, and the conductance of copper is high, and the thermal diffusivity of steel is good, can greatly reduce costs, and under identical area, copper covered steel is low weight, larger saving logistics cost; Two ends are the conical structure of fillet, and more convenient grafting, enhances productivity; Four sides at middle part are respectively equipped with projection, can improve the stability of grafting, guarantee the useful life of product.

The utility model is simple in structure, and cost is low, and Stability Analysis of Structures is easy to use, and can guarantee the useful life of product, enhances productivity.
