Features of High Current Spring Charge Pogopin


The functions of the high-current spring charging Pogopin mainly have three aspects: power transmission, data transmission and video transmission and data transmission functions. The high-current spring charging Pogopin can be processed into a magnetic charging cable by adding a wire harness part.

The service life of spring charging Pogopin charging pins is longer than other ordinary charging pins, because the plating thickness on the surface of spring charging Pogopin is much higher than the ordinary plating thickness. The more it can resist the corrosion of external environment, thus protecting the connector and prolonging the connector Service life. After the coating is enlarged, the service life will be extended.


The spring charging Pogopin has more stable performance than other common charging pins. The electroplating layer on the surface of the connector can increase the ductility of the connector, improve the durability, and improve the wear resistance. It is greatly improved. The electroplating layer on the surface of the connector can make the impedance of the connector More stable, so that the electrical performance of the connector is more stable.

The spring is the key component of the spring force in the spring-charged Pogopin, and the choice of the spring is also critical. The spring is made of high-carbon steel materials, and commonly used materials are SWP, stainless steel and beryllium copper. It is well known that SWP has good tensile properties. It can produce Good mechanical life and large elastic value; but this material is a high magnetic material, easy to rewind at high temperature, and corrosive. Therefore, it must be treated before use; as for stainless steel material, it is a kind of Low magnetic material, can withstand high temperature, so it is also selected as a commonly used material; about beryllium copper, it has excellent fatigue resistance and low impedance, but its tensile properties are relatively poor, usually when small wire diameters and high force values ​​are required. Not a good choice. The role of the spring-charged Pogopin cannot be ignored, because the performance requirements and use environment of the spring-charged Pogopin need to be considered when selecting materials.

Spring-charged Pogopins are used in smart terminal devices such as smart devices, so stable current signals and resistances are required to stabilize the performance of the devices. Therefore, spring-charged Pogopin manufacturers will first consider the resistance design of the thimble when designing to stabilize the performance of the device.

The spring-charged Pogopin needs to be plugged and unplugged repeatedly during the working process, and it also has very strict requirements on its working frequency.

With the continuous development of science and technology, smart devices are getting smaller and smaller, their functions are more and more powerful, and their appearance is becoming more and more changeable, so the spring-charged Pogopin still has high requirements for accuracy.

Many electronic devices now use waterproofing as a selling point, and the spring-charged Pogopin has this function.


The positive force of the spring-charged Pogopin working point is greater than 60g, and the holding force is stable 0.5kgf\/pin5.3. The thimble also has shock resistance. The thimble has a vibration frequency of 10-500HZ for 15 minutes, 1.2mm amplitude, power failure does not exceed 1μsec, contact impedance lt ; 100mOhm impact resistance.

Finally, the high-current spring charging Pogopin produced by professional charging pin manufacturers has strong wear resistance. The electroplating layer on the surface of the connector can isolate harmful substances in the environment, which not only reduces the damage to the connector, but also increases the wear resistance of the connector. sex.
