Abstract

An elongated grid tee for supplying low voltage power on a suspended ceiling comprising at least two electrically conductive paths electrically insulated from each other, extending lengthwise of the tee, and accessible for receiving or supplying electrical power at numerous locations along the length of the tee.

Claims

1. An elongated grid tee, with a reinforcing bulb at its upper side, for supplying low voltage power on a suspended ceiling comprising at least two electrically conductive paths electrically insulated from each other, extending lengthwise of the tee, and accessible for receiving or supplying electrical power at numerous locations along the length of the tee, at least one of the electrically conductive paths being disposed in an elongated plastic insulator cap mechanically attached to the bulb with prongs, the prongs extending from the plastic insulator cap and inserted and retained in receiving apertures in the bulb.

2. A grid tee as set forth in claim 1, wherein the conductive paths are symmetrically disposed on the tee relative to a central plane of symmetry of the tee.

3. A grid tee as set forth in claim 1, wherein the at least two electrically conductive paths are made of wire and are disposed in the plastic insulator cap.

4. A grid tee as set forth in claim 1, wherein the prongs are integral with the plastic insulator cap.

5. A grid tee as set forth in claim 1, wherein the prongs have barb-like configurations.
