Description

Connector structure with high protective performance Technical Field The present utility model relates to the field of electrical connectors, and more particularly, to a connector structure with high protection performance. Background In the prior art, a male head and a female head commonly adopt a screw crimping structure to realize the electric connection of a contact pin and a cable, namely, a cable conductor is pressed on a wiring terminal at the tail end of the contact pin by screwing a screw, so as to form a mechanical fixing and conducting path. However, the crimping design has obvious defects that the contact pins are connected with the cable through screw crimping, so that the physical distance (creepage distance) between each conductive part and the inner wall of the shell is excessively compressed, under the high-voltage working condition, partial electric arcs are easily formed by air ionization due to insufficient creepage distance between the conductive parts, the high temperature generated in the moment of electric arc discharge can directly ablate the surfaces of the contact pins and adjacent insulating materials, the inside of the connector is carbonized and burnt, the electric connector is easy to damage, and the potential safety hazard is large. Disclosure of utility model The utility model aims to provide a connector structure with high protection performance, optimize the internal structure of an electric connector, increase the creepage distance and improve the protection performance.
