At this time, by rotating the threaded bolt 42, the bottom end of the threaded bolt 42 is threadedly connected with the threaded cylinder 41 on the side of the base 1. As the number of turns of the threaded bolt 42 is increased, the downward pressing force of the top cover 5 is increased until the connecting wires are pierced, so that the connecting wires are electrically connected to the needle plate 2. At the same time, according to the thickness of the connecting wires, the number of turns of the threaded bolt 42 can be adjusted, so as to adapt to different connecting wires, thereby improving the practicability of the connector.
