Nowadays, with the progress of the market and the development of product technology, more and more consumers are not only concerned about the multi-function of the product, but also the appearance and body shape of the product. Pursue exquisite appearance, small and thin body. But it is a big challenge for most electronic product engineers to make and design such products. Because the structural design space and the standard specifications of the connectors must be considered, it is difficult for engineers to have a good choice to implement. The pogo pin has obvious advantages in terms of function and appearance. Its advantages are reflected in the use of structural space, assembly cost, service life, sample cycle and cost.
Current is the main function of the pogo pin, ranging from 20MA-10A. This is mainly related to the strict requirements of the diameter, height and electroplating of the pogo pin.
The needle of the pogopin pogo pin is required by the design, and the surface is required to be smooth into a small round hemisphere. But Tyco Hanze will cut the end of the needle that is in contact with the spring into a bevel. Do you know why? This is to ensure that the needle is always in contact with the needle tube when it is working. This design concept can ensure stable conduction of the product. In addition, the design of reverse drilling is the best choice for small-sized connectors, because it can meet the elasticity requirements of customers.
The length of the matching spring of this design is allowed to exceed the length of the needle tube, because under the condition of limited space, the design of reverse drilling is beneficial to obtain a more stable elastic stroke. The flat-bottomed design will cause the needle and the needle tube structure to be inaccessible due to certain conditions, which will cause the current to be unable to pass through the needle tube, and the needle tube wall will follow the spring straight, which causes the resistance to be too large and greatly reduces the voltage.
