Abstract

An electrical assembly for selectively supplying either 120 volts or 227 volts from a junction box to a high intensity discharge lamp fixture via a dual voltage ballast and a dual voltage electrical connector. The dual voltage electrical connector has dual operation capacity with input voltages of either 120 or 277 volts. The connector comprises a female connector having nine bores extending therethrough with female terminals fixedly coupled within four of the bores, and a male connector having nine bores extending therethrough with contact pins extending outwardly from four of these bores. When the connectors are coupled together in their first orientation, the male contact pin which conducts 120 volts of electricity engages the female terminal connected to a line wire. When the male and female connectors are manually rotated 180° relative to one another into their second orientation, a different pin, which conducts 277 volts, engages the line wire terminal. A latching device is fixedly coupled to the two connectors for releasably coupling the two connectors together.

Claims

1. An electrical assembly, comprising:

a lamp fixture with a pair of lamp terminals;

a dual voltage ballast electrically coupled to said lamp fixture, said ballast having a high voltage terminal, a low voltage terminal and a lamp wire terminal;

a first connector having first and second opposing ends with a plurality of first electrical terminals, one of said first terminals being electrically connected to a hot conductor of a power cable by a line wire, another of said first terminals being electrically connected to a neutral conductor of a power cable by a common wire and another of said first terminals being electrically connected to one of said lamp terminals of said lamp fixture by a first lamp wire; and

a second connector having a main body with first and second opposing faces with a plurality of second electrical terminals, one of said second terminals being electrically connected to said low voltage terminal of said ballast by a low input voltage wire, another of said second terminals being electrically connected to said high voltage terminal of said ballast by a high input voltage wire and another of said second terminals being electrically connected to said lamp wire terminal of said ballast by a second lamp wire,

said first and second connectors adapted to be positioned in first and second orientations, said second terminal with said low input voltage wire being electrically coupled to said first terminal with said line wire when said first and second connectors are in said first orientation, and said second terminal with said high input voltage wire being electrically coupled to said first terminal with said line wire when said first and second connectors are in said second orientation, said first and second connectors being rotatable relative to one another through 180°

to move between said first and second orientations.

2. An electrical assembly as claimed in claim 1, wherein

said first connector includes indicia on the side of said first connector directly adjacent and aligned with said first terminal connected to said line wire;

and

said second connector includes indicia on the sides of said second connector directly adjacent and aligned with said second terminals connected to said high and low voltage wires.

3. An electrical assembly as claimed in claim 1, and further comprising

a latch member for securing said first and second connectors together in said first and second orientations.

4. An electrical assembly as claimed in claim 1, wherein

said second connector includes arms integrally coupled to and extending from opposing sides of said second connector parallel to said terminals and past said second face.

5. An electrical assembly as claimed in claim 4, wherein

each of said arms form a shoulder.

6. An electrical assembly as claimed in claim 5, wherein

a portion of said first connector slidably fits between said arms when said first and second connectors are connected.

7. An electrical assembly as claimed in claim 1, wherein

said first connector includes a first set of apertures forming a first matrix at said second end, with said first terminals positioned within said first set of apertures, said first matrix has three rows and three columns to form a three by three matrix, a first row of said first matrix has first, second and third positions, a second row of said first matrix has fourth, fifth and sixth positions, and a third row of said first matrix has seventh, eighth and ninth positions, and

said second connector includes second set of apertures forming a second matrix at said second face, with said second terminals positioned within said second set of apertures, said second matrix has three rows and three columns to form a three by three matrix, a first row of said second matrix has first, second and third positions, a second row of said second matrix has fourth, fifth and sixth positions, and a third row of said second matrix has seventh, eighth and ninth positions.

8. An electrical assembly as claimed in claim 7, wherein

9. An electrical assembly as claimed in claim 8, wherein

said second terminal connected to said low voltage wire is coupled within said ninth position of said second matrix, and

said second terminal connected to said high voltage wire is coupled within said first position of said second matrix.

10. An electrical assembly as claimed in claim 1, and further comprising

a pair of latching members for securing said first and second connectors together,

said latching members being resiliently, pivotally and integrally coupled to opposing sides of said first connector and extending outwardly past said second end.

11. An electrical assembly as claimed in claim 10, wherein

said latching members have locking teeth for engaging shoulders formed on said second connector, thereby latching said first connector to said second connector.

12. An electrical assembly as claimed in claim 11, wherein

said connectors are molded and formed of rigid plastic.
