Abstract: The present invention discloses an electrical connector that includes a front zinc-alloy shell and a rear zinc-alloy shell. The front zinc-alloy shell and the rear zinc-alloy shell are made from die casting. The two shells are fitted tightly to provide shielding against electromagnetic interference. There is a cable plastic block with holding grooves to hold wires for electrical grounding and an isolation plate underneath the cable to provide electrical isolation. The holding grooves increase the connection strength of a connector cable. There is also a plastic block with an engagement hook. The engagement hook has a hook portion at one end and a curved fixing portion at the other end with an extending portion. The engagement hook provides an elastically supportive force. When a downward force is applied to the engagement hook, the curved fixing portion provides a counteracting force to press the extension portion against the front zinc-alloy shell.

Abstract: An electrical connector comprising: a shell, zinc alloy shell, body, front rubber core, rubber plug and wire; said zinc alloy shell body is provided with a holding groove penetrating from the front to rear ends; the front rubber core and the rubber plug are installed inside the zinc alloy shell body, and the shell set externally onto the zinc alloy shell body; the electric connector is provided with a hook unit, which penetrates the front rubber core, and is also coupled with the zinc alloy shell body; at the rear end of said hook unit, a locating part is molded, and also locked at the threading section of the wire. Compared with prior arts, the utility model features excellent air-tightness, anti-EMI capacity and compactness, thus improving the signal transmission capacity of the electric connector.
