Abstract
A sealed connector assembly connects a first cable to a second cable and includes female and male terminal assembly components each having molded in place a weather resistant sleeve that both covers the respective terminal assembly components, and defines openings or gaps which enable female and male contacts to be electrically connected and the sleeves to mechanically contact, thereby providing weather and element resistance. In a method for insulating the respective female and male terminals in a mold assembly, an O-ring applied to the terminal components to prevent liquid mold material from flowing over the electrical contacts.
Claims11
A method for forming insulation around an electrical contact, the method comprising:
- fitting an o-ring on the electrical contact;
- and
- inserting the electrical contact in a mold and filling the mold with a molten mold material, wherein
- during the molding process, the o-ring prevents the molten mold material from flowing onto the electrical contact wherein the electrical contact is connected to an electrically conductive cable that is partially contained within the mold.
A method for forming insulation around an electrical contact, the method comprising:
- fitting an o-ring on a head bar of a mold assembly;
- and
- inserting the electrical contact in a mold and filling the mold with a molten mold material, wherein
- during the molding process, the o-ring prevents the molten mold material from flowing onto the electrical contact wherein the electrical contact is connected to an electrically conductive cable that extends beyond the mold.
A method for forming insulation around an electrical contact, the method comprising:
- fastening the electrical contact to a conductive cable;
- fitting an o-ring on the electrical contact;
- fitting a head bar of an open mold assembly to the electrical contact;
- inserting the electrical contact fastened to the conductive cable into the open mold assembly, wherein the open mold assembly receives the conductive cable at a recess;
- closing the open mold assembly to encase the electrical contact fastened to the conductive cable in the closed mold assembly including the head bar;
- and
- injecting molten mold material into the mold assembly, wherein the o-ring prevents the molten mold material from flowing onto the electrical contact, wherein the electrical contact is connected to an electrically conductive cable that extends beyond the mold.
