The contact pin comprises a contact pin fixing seat 4 and a contact pin body 3 arranged on the contact pin fixing seat 4. The contact pin fixing seat 4 is of a T-shaped structure, the contact pin body 3 is fixed at the lower end part of the contact pin fixing seat, a group of springs 5 are downwards arranged on two sides of the top of the contact pin fixing seat 4, and the top of each spring 5 is fixedly connected with the contact pin fixing seat 4. The slot 7 is a T-shaped slot matched with the contact pin, the size of the slot is slightly larger than that of the contact pin, and the middle part of the slot is communicated. The horizontal molded surfaces at two sides of the inside of the slot 7 are respectively provided with a group of upright posts 8, the upright posts 8 correspond to the positions of the springs 5, and the diameters of the upright posts 8 are smaller than the inner diameter of the springs 5; when the connector is assembled, the upright post 8 stretches into the spring 5, the spring 5 is sleeved outside the upright post 8, and the bottom of the spring is contacted with the horizontal molded surface in the slot 7; the upright post 8 can play a certain guiding role on the movement of the pin.
