Method for manufacturing electrical connectors for enhancing coplanarity
View Patent ↗The present invention is a method for manufacturing an electrical connector comprising an insulative housing with a base side and an opposed side and lateral sides interposed between said base side and said opposed side and at least one conductive contact extending from the base side of the insulation in a first leg and then laterally adjacent the top side of the housing in a second leg. In this method there is provided a mold comprising a first die and an opposed second die all defining an interior cavity and an exterior area. A molding compound input port extends between the exterior area and the interior cavity and a contact receiving aperture extending through the first die from the exterior area to the interior cavity. The conductive contact is then positioned so that the first leg extends upwardly from the exterior area through the contact receiving aperture into the interior cavity. The first leg extends through said interior cavity, and the second leg extends laterally adjacent the opposed die. The interior cavity of the mold is then filled with a polymeric molding compound, and force is applied on the second leg to cause the second leg of the contact to bear against the second die.
1. A method for manufacturing an electrical connector comprising an insulative housing with a base side and an opposed side and lateral sides interposed between said base side and said opposed side and at least one conductive contact extending from the base side of the insulation in a first leg and then laterally adjacent the top side of the housing in a second leg, said method comprising the steps of:
(a) providing a mold comprising a first die and an opposed second die all defining an interior cavity and an exterior area, a molding compound input port extending between the exterior area and the interior cavity and a contact receiving aperture extending through the first die from the exterior area and the interior cavity;
(b) then positioning the conductive contact such that the first leg extends upwardly from the exterior area through the contact receiving aperture into the interior cavity and then through said interior cavity such that the second leg extends adjacent the opposed die so that the second leg is supported by the opposed die along its length on one side but is unsupported on an opposing side by either of the first die or the second die;
(c) then filling the interior cavity of the mold with a polymeric molding compound; and
(d) substantially simultaneously with step (c) causing the second leg of the contact to bear against the second die.
2. The method of claim 1 wherein the first die is a base die and the second die is a top die.
3. The method of claim 2 wherein the second die is superimposed over the first die.
4. The method of claim 3 wherein molding compound input port extends laterally through the mold.
5. The method of claim 4 wherein force is applied axially and upwardly on the first leg of the contact.
6. The method of claim 1 wherein force is applied downwardly on the second die.
7. The method of claim 4 wherein force is applied downwardly on the second die.
8. The method of claim 1 wherein the second leg of the conductive contact has an upper edge and a length and the upper edge is in contact with the second die.
9. The method of claim 8 wherein the upper edge of the second leg of the conductive contact is in continuous contact with the second die over the entire length of said second leg.
10. The method of claim 1 wherein in the completed connector the insulative housing has an upper side and the upper edge of the second leg is substantially parallel to the upper side of the insulative housing.
