First of all, we need to know what is "mini spring needle". Just like the name, "mini spring needle" is also a kind of pogo pin, but its volume is very small and its space utilization rate is very low (special space)
1、 Application of micro spring needle. It is a new type of connector system suitable for use in limited space. If the product requires flat design or modularization of the final product, butt connector should be avoided, so micro spring needle is an ideal choice. The connector is pushed directly onto the contact pad on the PCB.
2、 Product properties of micro spring needle. The rated current can reach 10a, the minimum pin pin spacing is 0.4mm (perforated plug) / 0.3mm (surface mount), and the service life is more than 50000 cycles. With high vibration resistance, it is suitable for data transmission or current transmission of light and thin mobile phone modules (display, audio jack, charging and other modules).
3、 Structure and working principle of micro spring needle. Like the common pogo pin, the micro pin connector consists of a thin tube containing a spring and a thimble. The spring pushes the needle to the contact pad on the printed circuit board to establish a reliable and vibration resistant electric contact.
