Cast forming methods for making sealed conductors
View Patent ↗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.
1. 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.
2. The method of claim 1 further comprising receiving the electrical contact in an aperture in a head bar of the mold.
3. 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.
4. The method of claim 3 further comprising through bolting the electrical contact through the head bar.
5. 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.
6. The method of claim 5 wherein the electrical contact is held in place in the mold assembly by the head bar.
7. The method of claim 5 further comprising:
curing the mold material within the mold assembly to form the insulation around the electrical contact;
removing the insulated electrical contact from the mold assembly; and detaching the head bar.
8. 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 a head bar of an open mold assembly;
inserting the electrical contact fastened to the electrically conductive cable into the open mold assembly, wherein the open mold assembly receives the electrically conductive cable at a recess and the electrically conductive cable extends beyond the mold;
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.
9. The method of claim 8 further comprising bolting the electrical contact to the head bar.
10. The method of claim 8 further comprising: curing the mold material within the mold assembly to form the insulation around the electrical contact;
removing the insulated electrical contact from the mold assembly; and detaching the head bar.
11. The method of claim 10 further comprising:
forming a first cable end in accordance and a second cable end wherein said first cable end is adapted to receive said second cable end so as to provide a water and weather tight seal when connected, and also permitting disconnection, reconnection and connection of additional cables in series, as needed.
