As an important component of connectors, contact terminals play a decisive role in the performance and price of connectors. Contact terminals usually appear in pairs, including the hole end (female end) and the pin end (male end). Generally, the hole end has a more complex structure compared to the pin end, making it the main research object of contact terminals.
According to the different structures of the female end, contact terminals can be divided into slotted terminals, crown spring terminals, and wire spring terminals. Slotted terminals have multiple contact pieces. Compared to crown spring terminals and wire spring terminals, slotted terminals have a simple and sturdy structure, making them suitable for harsh environments. The crown spring terminal is equipped with a claw structure inside, and when the pin is inserted, the claw can use its own elastic force to clamp the pin, forming stable contact. Compared to slotted terminals, crown spring terminals have stable contact, soft insertion and extraction force, and are suitable for high current equipment. The wire spring terminal is in contact with the insertion pin through hyperbolic copper wire, providing a insertion and extraction life of over 100000 times, suitable for various types of equipment with high insertion and extraction frequency and high reliability requirements.
