ABSTRACT:
A self-contained, readily-attached electrical connector unit for fluorescent light fixtures is disclosed which hangs from and attaches to the separate prongs of a pair of single or double pronged fluorescent bulbs. The device provides a convenient means for providing auxillary power e.g., connecting extra lighting or a motor for lighted or animated displays to ceiling fixtures and eliminates extraneous wiring and brackets normally used for these purposes, and further eliminates the use of battery-powered motors with these inherent shortcomings and expense.
In one embodiment a housing unit for an outlet plug and motor drive is disclosed having a pair or receptacle cups engageable over the ends of a pair of fluorescent tubes for making electrical connection to said outlet and/or motor. In another embodiment the receptacle cups are flexibly attached to the housing so as to be engageable with the prongs of variously spaced tubes. The receptacle cups are insulated and house cooperative conductor discs or connectors which make the electrical connections and are easily and safely attached and detached.
