A high current pogo pin is a precision instrument of three parts: a needle tube, a spring, and a needle shaft. Qincheng will then describe the differences in the production processes of the needle shafts of various pogo pins.

The distinction between the needle shafts of pogo pins

1. Pogo pin needle shaft with flat head

Easy to produce and inexpensive;

2. Pogo pin needle shaft with sectional hypotenuse

It is currently widely used in the industry and has good electrical properties.

The plant now has two types of bevel angles: the first is 12°. This bevel angle allows the needle shaft to be pre-positioned during assembly, and the length of the needle seat must be kept short to save space. The second variety is 218°, which is currently more widely utilized in the factory. It necessitates a somewhat lengthy needle seat that satisfies the high resistance value of the tube wall after assembly.

3. Pogo pin needle shaft with anti-drilling properties

Specifications: For use in products with long tightening strokes.

There are now two types of reverse drilling angles in the industry: the first is 120°, which is easier to drill. The second variety is 160°, tougher to drill but can enhance spring positioning space.

The cost distinction between the three types of pogo pins

Single-needle thimbles are often larger than 1MM in diameter. Because the gold-plated surface area is huge, our prices are higher. However, if the diameter is tiny, the complexity of production increases and the price necessarily rises.

If the diameter exceeds 0.5, one head can move, but the other cannot, the smaller the diameter, the higher the price.

Double-ended needles cost more than the previous two types, and both can move. This is the one I sell the most of, and I am quite familiar with it. The smaller the diameter, the higher the price, and it can reach a diameter of 0.15MM.
