As an indispensable part of electronic products, the charging needle is well designed, which can not only save space, but also greatly reduce the difficulty of assembly. In recent years, electronic products have been developed to be light, thin and small. In order to save space, electronic manufacturers have made the charging pin adapter expand rapidly. Let's learn about the characteristics of the charging pin?
1、 Stable contact resistance
Charging pin connectors are mostly used in intelligent devices and other intelligent terminal devices, so stable current signal and resistance are required to stabilize the performance of the device. For the consumption of charging pins, the ordinary static impedance is 50 milliohm, and the minimum can be as low as 30 milliohm.
2、 Operating frequency and duration of charging pin
The charging pin adapter needs to be plugged and unplugged repeatedly during operation, which makes a very strict request for its working frequency. The service life of the charging pin can reach about 10000 times, and 5W times or 10W times when the request is severe.
3、 Small size, high density and light weight
With the development of science and technology, smart devices are becoming smaller and smaller, more functional, and more changeable in appearance. Therefore, there are high requirements for the volume and precision of the charging pin adapter, and the small diameter consumed in batch can reach 0.6mm.
4、 Waterproof and moisture-proof
At present, many electronic devices take waterproof as a selling point, but the charging needle adapter does have this function. In the development, the waterproof and moisture-proof function of the charging needle adapter will be better.
5、 Mechanical properties of charging needle
The positive force at the working point of the charging needle adapter is greater than 80g, and the holding force is stable at 0.5kgf/pin5.3. Not only that, the charging needle also has shock resistance. The shock resistance of the charging needle achieves 10 ~ 500Hz vibration frequency in 15 minutes, 1.2mm amplitude, and power failure does not exceed 1 μ SEC, contact impedance < 100mohm.
