An electrical connector has a contact having redundant contact points for interconnection to an electrical pin terminal. The contact portion is defined by a base section of the terminal having upstanding wall sections defined by upstanding strap portions and an intermediate beam section. The intermediate beam section has a first constricted portion defining parallel and opposed constricted walls, where each constricted portion includes inwardly directed C-shaped projections defining internal contact surfaces for contact with a pin. The contact has an upstanding polarizing feature which is wider than the upstanding wall sections of the contact member. The corresponding housing includes a projection on the internal surface of the cavities which allows the polarizing feature of the contact to pass beneath, but which cannot allow improper loading of the terminals within the respective terminal receiving cavities.

Electrical pin contact and housing

A fluorescent lighting assembly (,) includes a ballast lampholder subassembly (,) located at one end of a troffer (,) and at least one lampholder connector (,) located at the opposite end. The ballast lampholder subassembly (,) includes ballast circuitry connected to fluorescent lamp terminals (,) all positioned within a ballast lampholder housing (,). A molded ballast lampholder cover (,) encloses three sides of the ballast lampholder subassembly and a stamped metal plate forms the ballast lampholder base (,), with the ballast circuitry located on a circuit board (,) positioned on the interior surface of the base. Integrally molded lampholders (,) extend from channels (,) on the cover (,) and are positioned between larger enclosure sections (,) which provide space for larger ballast components. Fluorescent lamp terminals (,) are inserted from the interior of the cover into cavities (,) in lampholders (,), and lead wires connect the terminals to the printed circuit board. Lampholder connectors (,) including integrally molded lampholders (,) are located at the opposite end of the fluorescent lighting assembly (,).

Lighting assembly for multiple fluorescent lamps

A fluorescent lampholder connector (50, 150) for use in a fluorescent lighting assembly (2) includes a molded lampholder connector housing having spaced-apart molded lampholders (51, 150) extending upwardly from a lampholder connector base. Each of the lampholders includes a pair of terminal cavities (52, 152) opening on a lower surface of the connector housing. Fluorescent lamp terminals (17) are disposed in respective ones of the terminal cavities. In one embodiment, the connector (50) has two lampholders (51), and lead wires (57) connect the terminals in one lampholder to the terminals in the other lampholder. In another embodiment, the connector (151) has three lampholders, a bus wire (157) extends along the lower surface of the connector housing, and lead wires (161) connect the terminals to the bus wire.
