Abstract
The utility model relates to a contact pin for current shunting. The contact pin comprises a cylindrical pin body (1) and a base (2), wherein the bottom of the pin body (1) is connected with the base (2) each other, and a plurality of equilateral pyramid-shaped or semispherical annular bulges (4) are integrally formed on one surface of the base (2), which is connected with the pin body (1). The plurality of annular bulges (4) are annularly distributed around a central axis (8) of the pin and closely connected mutually without gaps. A connection part between the bottom of the pin body (1) and the base (2) are inwards sunk, and the radius of the cross section of the connection part is smaller than that of the cross section of the pin body (1). An annular sunk zone (7) is formed between the plurality of annular bulges (6) and the sunk part between the bottom of the pin body and the base. The contact pin disclosed by the utility model has the advantages of eliminating gaps caused by scratch marks of barbs, ensuring that the pin and a copper plate are seamlessly riveted, improving the mechanical and electric performances of the contact pin and increasing the reliability of connection between the contact pin and the copper plate.
Description
Technical field
The utility model relates to a kind of contact pin that is used for the electric current shunting, belongs to electronic information field.
Background technology
Electric current shunting main line is the tendency solution that present information electron trade solves big electric current, the distribution of high reliability electric current.The contact pin that electric current shunting main line is used is a critical component of electric current being shunted connection, and exigent tightness can guarantee that like this product contact pin in long use keeps good mechanical to contact with electricity with copper coin.Present contact pin adopts the design of projection hangnail type; As shown in Figure 1; Contact pin is designed with hangnail 3 by second end place of needle body 1, base 2 and needle body 1; Therefore the thorn point direction of hangnail 3 is then lived the contact-making surface of copper coin 4 inwalls through the thorn pinnacle of hangnail 3, thereby is prevented that contact pin from withdrawing from outward down in being riveted to copper coin 4.But this contact pin has corresponding drawback, and the contact surface at contact pin and copper produces cut in the process of riveted joint at first easily, and is secondly as shown in Figure 1, after contact pin inserts, causes contact-making surface empty the connection to occur, is unfavorable for the fastening of contact pin and electrically contacts.The loosening phenomenon with poor electric contact of contact pin especially appears in the long-term use of product easily.
The utility model content
The purpose of utility model has provided a kind of contact pin that is used for the electric current shunting, and traditional contact pin is transformed, and changes hangnail of the prior art into upright annular protrusion, effectively solves problems such as hangnail scratch copper sheet and generation space.
In order to reach above-mentioned utility model purpose, the technical scheme that the utility model adopted is:
A kind of contact pin that is used for electric current shunting comprises cylinder bodily form needle body and base, and needle body is connected mutually with base in the bottom, and the one side that is connected with needle body at base is one-body molded to have a plurality of equilateral pyramid shapes or hemispherical annular protrusion.
Preferably, above-mentioned a plurality of annular protrusions are with the circular distribution in the axis of contact pin, adjacent each other connection, junction tight.
Preferably, the junction between above-mentioned needle body bottom and the said base caves inward, and junction cross section radius is less than the cross section radius of needle body.
Preferably, form the annular recess band between the junction of above-mentioned a plurality of annular protrusion and said depression.
Compared with prior art, the contact pin that the utility model provides has been removed because the space that the scratch of hangnail causes makes contact pin and copper coin produce seamless riveted, has improved the mechanics and the electric property of contact pin, has increased the reliability that contact pin is connected with copper coin.

Reference numeral: 1-needle body; The 2-base; The 3-hangnail; The 4-copper coin; The 5-space; The 6-annular protrusion; The 7-hollow zone; The 8-axis.
Embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, the utility model is done further to describe in detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 3; The contact pin that is used for the electric current shunting that the utility model provides; Comprise cylinder bodily form needle body 1 and base 2, needle body 1 is connected mutually with base 2 in the bottom, and the one side that is connected with needle body 1 at base 2 is one-body molded to have a plurality of equilateral pyramid shapes or hemispherical annular protrusion 4.A plurality of annular protrusions 4 are with the axis 8 circular distributions of contact pin, adjacent each other connection, junction tight.Junction between needle body 1 bottom and the said base 2 caves inward, and junction cross section radius is less than the cross section radius of needle body 1.Form annular recess band 7 between the junction of a plurality of annular protrusions 6 and said depression.
Compare with prior art such as Fig. 1 and 2, the contact pin that the utility model provides has at first removed hangnail 3, has increased annular protrusion 4 and hollow zone 5.In concrete use, as shown in Figure 4, annular protrusion 4 embeds in the copper coin 2 in the process that presses; Fixing plug pin can not rotate it, secondly, and when annular protrusion 4 gets in the copper coin 2; Can push copper coin; Make copper towards the place distortion of having vacant position, will fill hollow zone 3 very naturally like this, make whole contact pin and copper coin the tight riveted occur.The effect of hollow zone is fixing plug pin, makes it produce displacement along self long axis direction.
The contact pin that the utility model provides; Contact pin to traditional improves, and has removed hangnail, has increased the annular protrusion that tip is directed upwardly; And between the root of convexity and contact pin main body, be formed with hollow zone; Insert in the process of copper sheet in reality, filled in hollow zone by the copper sheet part of annular protrusion pointed nose extruding, thereby reach the purpose of fixedly inserting and can not form space and scratch copper sheet.
The above; It only is practical implementation case in order to explanation the utility model; But be not in order to limit the practical range of the utility model; Such as those skilled in the art must be covered by the scope of the utility model claim not breaking away from all equivalence changes of being accomplished under indicated spirit of the utility model and the principle or modifying.
