  • Process of producing electrical terminal with electrical contacts and system thereof
    Patent number: 5153989
    Abstract: A process of producing electrical terminals with electrical contacts, including the steps of: a first step for continuously providing contact mounting holes at a first predetermined distance in an electrical conductive base and conveying the electrical conductive base in a first direction; a second step for continuously providing contact holding holes at a second predetermined distance in a carrier, continuously fitting electrical contacts into the contact holding holes and conveying the carrier in a second direction perpendicular to the first direction; a third step for positioning the electrical contacts in the contact holding holes of the carrier to the contact mounting holes of the electrical conductive base; a fourth step for fitting the electrical contacts in the contact holding holes into the contact mounting holes of the electrical conductive base; and a fifth step for cutting the electrical conductive base to separate electrical terminal each having an electrical contact at an end thereof.
