Description

Technical Field

[0001] The utility model relates to the technical field of charging spring pins, in particular to a charging spring pin capable of passing large current. Background Art

[0002] The charging spring pin can be understood as a PIN spring pin. The PIN pin is a metal material used in the connector to complete the conduction (transmission) of electricity (signals).

[0003] The spring pin is a commonly used connector. It has many names, such as: also known as ejector pin connector, POGOPIN connector, spring ejector pin, spring probe connector, etc.

[0004] Spring probes are generally used for precision connections in electronic products such as mobile phones, communications, automobiles, smart wearables, drones, smart robots, aerospace, etc., and can improve the corrosion resistance, stability and durability of these connectors.

[0005] The spring probe is a carrier for transmitting signals and currents. It is hardware for achieving power supply or conduction. Most of the time, the spring probe needle contacts the copper wall obliquely downward. The spring of the spring probe bears a small amount of gravity, so the inner wall of the copper sleeve is required to be smooth.

[0006] With the popularization of electronic devices, the application of spring probes is becoming more and more extensive. It is widely used in signal transmission. The most common one is the mobile phone antenna pin. The advantage of using spring probe antenna and motherboard is that the inductance is small and the interference to the radio frequency signal is weak.

[0007] At present, most charger spring pins with cylindrical structures, while having a certain telescopic buffer function, only rely on internal springs for telescopic and connection, and are fixed as a whole by welding. When the internal spring becomes detached and loose, it is inconvenient to repair and re-weld it. Utility Model Content
