Connector structure

A connector structure, comprising:

• an insulating housing, comprising a base seat and a hollow cylinder connected to the base seat, the hollow cylinder defining a through slot and comprising a limiting structure, the through slot penetrating the base seat and the hollow cylinder along a vertical direction, the limiting structure arranged on an end of the through slot, the limiting structure comprising a pair of limiting surfaces and a pair of limiting concave-arc surfaces, the limiting surfaces parallel to each other and arranged oppositely, the limiting concave-arc surfaces arranged oppositely and respectively connected to opposite sides of each of the limiting surfaces;
• and
• a contact pin, configured to detachably insert to the insulating housing along the vertical direction, the contact pin comprising a inserted portion and an exposed portion, the inserted portion comprising a positioning section connected to the exposed portion, the positioning section comprising a pair of positioning surfaces and a pair of positioning convex-arc surfaces, the positioning surfaces parallel to each other and arranged oppositely, the positioning convex-arc surfaces arranged oppositely and respectively connected to opposite sides of each of the positioning surfaces;
• wherein when the contact pin is not inserted into the insulating housing, a limiting spacing is defined between the limiting concave-arc surfaces, a positioning spacing is defined between the positioning convex-arc surfaces, the positioning spacing is greater than the limiting spacing;
• wherein when the contact pin is inserted into the insulating housing, the inserted portion is inserted in the through slot, the positioning section is fixed in the limiting structure, each of the positioning surfaces is abutted against to each of the limiting surfaces, each of the positioning convex-arc surfaces is abutted against to each of the limiting concave-arc surfaces.
