Correct method to avoid dimension error of spring probe

　　The needle tube and needle head of spring probe are turned and milled by copper bars one by one; the traditional processing method is to use cutter to process, and the processed products have low precision and cost; the energy consumption is applied in the application fields with low precision requirements for spring probe products.

　　With the popularity of smart phones and smart wear, electronic products are becoming more and more thin and compact, which makes the originally limited space become smaller and smaller; in order to meet the market demand, the volume of spring probe connector is becoming smaller and smaller, and the accuracy requirements of spring probe are also higher and higher.

　　The precision of spring probe products processed by different processing equipment is different, so how to avoid the dimensional error of spring probe?

　　First of all, the surface finish of high-precision spring probe products is very high. The surface finish of the outer wall of the needle tube does not have a great influence on it, but on its inner wall. If the surface is very rough, the friction coefficient of the spring probe during elastic expansion and contraction will be particularly large, which may cause stuck. More importantly, if the friction coefficient is too large during operation, it will lead to the outer wall of the spring probe and the needle tube The wear of the inner wall of the spring probe is very serious, so the service life of the spring probe is reduced.

　　Secondly, the size error of spring probe products will be larger if the products are processed by equipment with low precision, which will bring trouble to the later assembly and application, and may not match well.
