Description
Technical field
The present invention relates to electric connection technology field, in particular to wire spring plug bush.
Background technology
Connector is the important device for conducting electric current.In modern industry, especially in terms of electrical equipment, the application of connector
It is extremely wide.For metal terminal as the important component in connector, it is very high to manufacture the requirement of processing to it, makes every effort to economical, simplifies,
With control cost.Metal terminal is mostly using the combination of wire spring plug bush and contact pin at present.Wire spring plug bush includes body, cap bag and more
Root coil spring, body have jack.More coil springs are inserted into jack, one week close-packed arrays of the coil spring along the edge of body, stretched
The part for going out jack is bent to body outer wall, coil spring is hung over the port of jack, then cap bag is enclosed on to the end of body, make line
Spring is stretched out in gap of the part of jack between cap bag inwall and body outer wall, and cap bag and body are led to using interference fit
The part that coil spring is stretched out outside jack is crossed to fix.But using wire spring plug bush, because its coil spring is relatively more, and the assembling of coil spring
Also it be unable to do without artificial means at present to carry out, therefore, assembling is time-consuming, and efficiency is low, virtually adds the manufacturing cost of product, simultaneously
Because existing most of wire spring plug bush structures are not compact, effective contact area of coil spring is small when in use, causes to go out when using
The problem of existing service life is short, and contact resistance is high.
Therefore, as shown in figure 1, Chinese patent CN200910208863.7 discloses a kind of wire spring plug bush, the wire spring plug bush
Including cap bag 4 and body 1, body 1 has jack, and cap bag 4 is fixedly connected with one end of body 1 and forms a gap, wherein, body
The edge of the one end being engaged with cap bag is provided with multiple necks 2, and one end of coil spring 3 is located in jack 11, the other end of coil spring 3
In through neck 42 and it is sandwiched in the gap that cap bag 4 and body 1 are formed.The bottom of jack is provided with groove 12, and wire spring plug bush is also
Including limit plug 2, limit plug 2 includes positioned at the part of groove 12 and is located at jack 11 positioned at the part of jack 11, limit plug 2
Gap is formed between part and the inwall of body 1, the other end of coil spring 3 is located in gap.
But there is following defect in wire spring plug bush disclosed in the patent：On the one hand, cap bag space-consuming in front end is more so that whole
Body structure is not compact；On the other hand, the presence of cap bag 4 and limit plug 2 make it that structure is excessively complicated, and manufacturing cost is high, and technique is numerous
It is trivial.
The content of the invention
