A connecting structure includes at least one conductive terminal having a body, a conducting portion connected below the body, a pre-breaking portion provided at an upper end of the body, and a temporary soldering portion connected above the pre-breaking portion; a first strip connected to the conducting portion; and a second strip soldered to the temporary soldering portion. A method for manufacturing an electrical connector includes: forming a first strip and at least one conductive terminal connected thereto; soldering a second strip to the temporary soldering portion of the conductive terminal; separating the conducting portion of the conductive terminal and the first strip; operating the second strip to control the conductive terminal to be mounted to a housing; and disconnecting the pre-breaking portion of the conductive terminal, and removing the second strip and the temporary soldering portion of the conductive terminal.
