The invention discloses a cold extrusion method for improving the strength and the service life of a connector, and belongs to the technical field of cold extrusion molding of metal products. The cold extrusion method comprises cutting, heat treatment, extrusion and surface treatment; and a method in which the heat treatment process and the surface treatment process are adopted, the allowance is increased, and movable extrusion is carried out according to the reserve for shifting the position of a metallographical flow line collecting mark is adopted, so that the service life of the connector is prolonged by 10 times or above. The finished product of the connector has the characteristics of fullness, smoothness, fineness, enough size, high strength and stable quality.
