The invention discloses a fast wiring interlocking electrical connector, which comprises a plug and a socket. The plug mainly comprises a cover plate, a base, a wire locking mechanism and a sliding block, wherein the base comprises an elastic locking mechanism which is arranged outside the base; the wire locking mechanism and the sliding block are arranged in the base. The socket mainly comprisesan integral base and monolithic Z-shaped compound spring leaves, wherein the tail ends of the Z-shaped spring leaves have a needle eye-shaped flexible pressure-welded structure and a rectangular welded structure respectively. The plug realizes fast wiring and wire locking by pushing the intermediate sliding block to commonly drive the opening and closing of wiring holes of two wire clamping springs. The elastic locking mechanism of the base realizes interconnecting locking and unlocking with the socket. The socket realizes the regulation of a contact distance between two poles and a distance between holes reserved at a board end. Simultaneously, the connector still has the advantages of simple structure, convenience and high speed of use, high connection reliability, high current carryingcapability and the like.
