We provide all kinds of high-precise solid pin milled pieces and connectors, which are used together with pogo pin. They arewidely used in intelligent wearable fields such as TWS headsets, watch/bracelet,fully meet the requirements of customers onappearance, assembly and corrosion resistance.
- High salt spray resistance 1,000H+ .
- High Perspiration resistance 240H+ .
- Meet the requirements of biocompatibility. (such as nickel release test)
Solid pin type
According to the welding type,solid pin can be divided into 3 types: flat bottom type, plug-in plate type and welding wire type;Pin can be shipped separately, or it can be combined with plastic to form solid pin connector for shipment.
Contact surface of inner concave surface and convexarc surface
The solid pin can be designed with curved surface, which makesthe design of earphone, smart bracelet and other products moreflexible.
Flat contact surface
Flat contact surface is the most widely used,and it is relatively easy to process and control.
