Abstract: A pogo pin connector includes: a piston cylinder, a cylindrical piston with its bottom latched into the piston cylinder and capable of moving along the piston. cylinder axially; a needle head partially latched into the piston and capable of rotating freely in the piston, a spring installed between the needle head and the bottom of the piston cylinder for pushing the needle head to the outside, such that the top of the needle may protrude from the top of the needle head under the elastic effect of the spring. The needle head is latched to the top of the piston under the elastic effect of the spring and the top of the needle head protrudes from the piston to contact with a connecting member for an electrical conduction when there is no external pressure.
