The invention relates to the field of electrical connection and in particular to a crimping connector. In a crimping connector housing, a conductive piece is disposed on one side of a wire duct, and acrimping reed is disposed on a side opposite to the conductive piece. The crimping reed is movably installed in the housing in a direction toward the conductive piece. The housing is provided thereinwith an elastic member which provides an acting force for the crimping reed along its moving direction. An operating handle has a cam pressing surface which is abutted against the crimping reed alongits moving direction and constitutes a cam push rod model with the crimping reed in cooperation with the elastic member. When the operating handle is rotated, the crimping reed can move close to andaway from the conductive piece so as to compact and loosen the conductive piece. In this way, the elastic member provides an acting force for translation for the crimping reed to loosen the wire, provides the elastic force indirectly for the operating handle through the crimping reed to keep the operating handle in a wiring state and a crimping state, which greatly improves the crimping reliability and extending the service life of the connector.
