Structure of pogo pin connector
With the development of the market and the upgrading of product technology, more and more consumers are not only limited to the multi-function of the product, but they are also pursuing a stylish appearance and a small and thin appearance. But to manufacturing and design, such a product is a huge challenge for all electronic product engineers. Because of the structural design space and the standard specifications of the connectors, it is difficult for engineers to have a good choice to complete it. In addition, pogo pins have obvious advantages in terms of assembly cost, service life, sample cycle, and cost in the structural space.
The main function of the pogo pin is overcurrent, ranging from 20MA-10A. Mainly, there are strict regulations on the diameter, height, and plating requirements of the pogo pin.
The pogo pin needle requires a smooth surface into a small round hemisphere. Needle design requirements for POGOPIN pogo pins.
Bevel: In order to ensure that the needle is always in contact with the needle tube when working, Tyco Hanze cut the end of the needle that is in contact with the spring into a bevel. This design concept can ensure a low and stable contact impedance to ensure the stable conduction of the product. The back-drilling design is a good choice for small-sized connectors, which can meet the elasticity requirements of customers
The length of the matching spring of this design can exceed the length of the needle tube. In the case of limited space, the design of reverse drilling can obtain a stable elastic stroke. The flat-bottomed design will not be inaccessible due to certain conditions on the structure of the needle and the needle tube, which will cause the current to go through the needle tube, and the wall of the needle tube will go straight along the spring, which will cause the resistance to be too large and the voltage will drop in a large arc.
We are a pogo pin manufacturer, a high-tech enterprise focusing on precision connection, technology development as the core, and integrating R&D, production, and sales.
