Following extensive research, development, and accumulation, Rtench chooses to use an oval spring structure. The compression force and life of the spring can be precisely determined by precise design calculations. 

After long-term research and development and accumulation, Rtench adopts an oval spring structure design. Through accurate design calculations, the spring's compression force and life can be accurately calculated. Through accurate design calculations, the spring's compression force and life can be accurately calculated. Even at a very low 0.30N working elasticity, stable contact and long life can be obtained. At present, many earbud-type Bluetooth wireless headsets and smart wearable electronic mobile terminals that rely on magnets are using a large number of low-elasticity Pogo Pin connectors for connection charging or top antenna signal. At the same time, low-elastic springs are also used in products with multiple pins, such as the 20Pin connector male and female mating products for vertical contact by the weight of the terminal product.
