Abstract
A method is disclosed for manufacturing insulated electrical terminals in which the insulation is uniformly distributed over all portions of the terminal which are to be insulated. The present invention concerns a treatment of the terminal between the stages in which the terminal is initially stamped and formed and the stage in which the coating of insulation material is applied to the terminal. In this intermediate stage the terminal is subjected to a treatment which reduces any sharp edges, burrs, or the like to have radii of curvature thereby allowing the insulation coating to uniformly flow on the entire surface of the terminal.
Claims17
A method of producing insulated electrical terminals comprising the steps of:
- stamping a continuous series of terminals from a flat web of metal stock, each said terminal having at least one insulation piercing portion;
- subjecting all of said at least one insulation piercing portion of said terminal to an erroding medium which reduces all sharp edges of said portion to radii of curvature;
- and
- applying a coating of insulative material to said portion of said terminal.
A method of producing an electrical terminal having an insulation piercing portion with a coating of insulation at least partially covering said portion, said method comprising the steps of:
- forming a continuous series of terminals from a web of metal stock material, each said terminal having an insulation piercing portion;
- reducing all sharp edges, projections, burrs and the like on at least said insulation piercing portion of said terminal to curved surfaces of transition;
- and
- coating said insulating piercing portion of said terminal with a dielectric material.
An improved, partially insulated electrical terminal having a coating of insulation at least partially covering an insulation piercing portion of said terminal, said terminal being produced by the steps of:
- forming a continuous series of terminals from a web of metal stock material, each terminal having at least one insulation piercing portion;
- reducing all sharp edges, projections, burrs and the like on said at least one portion of said terminal to curved surfaces of transition;
- and
- coating said at least one portion of said terminal with a dielectric material.
