Causes of unstable signal current in pogo pin connector.Spring needle Production

　　The pogo pin connector is mainly used for energization and conduction. Most of the pogo pin connector needles contact the copper wall obliquely below, and the pogo pin connector spring bears a small amount, so the inner wall of the copper sleeve needs to be kept smooth. For example, the pogo pin connector factory needs to be made into a non-beveled surface, and the bottom is flat, most of the current needs to be conducted through the spring, which requires relatively high springs. Of course, it is necessary to ensure that the signal current does not fluctuate when the current suddenly increases. So what are the reasons for the unstable signal current when pogopin connector is used?

　　1. The size of the pogo pin connector

　　The size of the 5G radio frequency pogopin connector is mainly determined by the design strength, current load and shape, but the cost of a large diameter will increase a lot. The needle tube of the standard pogo pin connector is generally 1.5, and the needle is 0.9, which is a relatively economical choice.

　　2. The height of the pogo pin connector

　　The height of the 5G radio frequency pogopin connector is mainly determined by the working height, the height during working compression, and the accuracy when the matching parts are installed. Usually the compression stroke is about 70% of the total stroke, and the common working stroke is 1.0mm.

　　Three, pogo pin connector current load

　　5G radio frequency pogopin connector has different requirements for current load. The entire design parameters of pogo pin connector need to be changed and adjusted accordingly.

　　The design concept of 5G radio frequency pogopin

　　1. Needle bevel structure

　　The design concept of 　　pogo pin spring thimble can ensure low and stable contact resistance, and can ensure the stable conduction of the product.

　　2. Needle punching structure

　　5G radio frequency pogopin spring thimble The length of the matching spring can exceed the length of the needle tube. When the space is limited, the reverse drilling design is adopted, which is beneficial to obtain a stable elasticity and stroke.

　　3. Needle flat bottom structure

　　In this design, because the pogo pin spring thimble needle and the spring thimble needle tube cannot be contacted under special circumstances, the current cannot go through the needle tube, and the tube wall will follow the spring, resulting in excessive resistance and greatly reduced voltage, leading to electronic products The current fluctuates.
