Abstract

The present invention provides an electrical connection structure, a charging connector, and a connection terminal, which are applied to a printed circuit board (PCB). The PCB has a connection hole. The electrical connection structure comprises multiple metal springs and a connection terminal, which are fixed to the PCB around the hole. When the connection terminal is inserted into the hole, it makes contact with the metal springs, thus establishing an electrical connection between the terminal and the PCB. In the electrical connection structure of the present invention, the connection terminal maintains excellent contact with the metal springs, ensuring a stable connection between them and the PCB. Furthermore, the metal springs provide multiple signal sensing points, ensuring the stability of the signal transmission.Furthermore, the metal springs offer excellent performance and can be connected and disconnected repeatedly, which prolongs their lifespan.
