Pogo Pin Connector High Current Pin

Pogo Pin Connector High Current Pin

The pogo pin is the core part of the precision connector used in communication base stations or terminals, automobiles, medical, unmanned aerial vehicles, industry, aerospace, and other fields. Both signals and current can be transmitted through the pogo pin. 

With the development of society, more and more products require high current transmission and rapid charging, and even some products also have lightning protection requirements, which also makes the spring thimble more and more current to withstand. As is a Pogo pin technology company, We have the following manufacturing techniques for pogo pins:

Drill design spring thimble: This structure has a flat-bottomed needle, simple processing, lowest cost, but there is a higher risk of the needle and the needle tube not contacting and the risk of power failure, and the contact impedance of the product is also Very large, products with this structure are usually only used in occasions where the product requirements are particularly low and the current is particularly small. At present, regular large companies basically do not choose products with this structure.

Sectional bevel spring thimble: The needle of this structure is a sectioned bevel, the processing is more complicated, the cost is relatively high, but the product needle and the needle tube are in good contact, and the contact impedance is also very small, mainly because of the spring It has a lateral force component to the needle elasticity so that the needle and the needle tube are in stable contact. This structure is widely used in the spring thimble factory, and it is only used in small and medium current situations.

Three, steel ball spring thimble: This structure needle is a cut bevel, and a steel ball will be added under it. This structure is complicated to process, the cost is relatively high, and the needle tube space occupied is also large, but the product needle and the needle tube are in good contact, and the contact impedance is also very small. The lateral force component, which allows stable contact between the needle and the needle tube. The steel ball also adds a current flow channel. This structure is widely used in spring thimble factories, and it will be used in situations where the current is medium and large.
