Abstract
Abstract A coupling device which allows for quickly changing electrical fixtures without rewiring. The quick change mounting fixture comprises a combined electrical and mechanical two-piece male and female fastening device. The invention allows for consumer as well as professional installation and detachment of fixtures by providing an easy and safe method. All wires and contacts are self contained and shielded from accidental contact. The invention comprises a female receptacle plate for mounting to a standard ceiling or wall mounted electrical junction box, a male tap support plate which also functions as a fixture support, a block terminal support, where contacts and wire routes are located, and a shield cover.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
281 words
An electrical quick connect power tap system comprising: A. a socket comprising: a. a front surface, b. a pair of concentric semicircular slots in said front surface, each terminating at each end at an opening wider than said slot, the opening at one end being wider than the other, c. a pair of socket contacts spaced away from and to the rear of said front surface and presenting a radially disposed surface generally perpendicular to said front surface, and d. insulating surfaces surrounding each of said contacts and preventing contact therewith except on said generally perpendicular surface from the rear of said front surface and arcuately with respect to the axis of said concentric slots, and B. a plug comprising: a. a front surface, and b. a pair of uprights adapted to fit through the wider openings of said slots, each of said uprights comprising portions of three widths, a first narrow portion narrower than the one of said slots into which it fits, a second wider portion fitting into the narrower of the two wider openings of the one of said slots into which it fits, and a third widest portion fitting into the widest of the two wider openings of the one of said slots into which it fits, said portions being spaced from the front surface of said plug in order of the narrowest, wider, and widest portions; and c. a pair of plug electrical contacts adapted to mate with said female contacts wiping against them in an axial motion toward said front surface of said socket when said wider portion of said uprights are fitted into the two narrower of the two wider openings of said slots.

An electrical quick connect power tap system comprising: A. a socket comprising: a. a front surface, b. a pair of concentric semicircular slots in said front surface, each terminating at each end at an opening wider than said slot, the opening at one end being wider than the other, c. a pair of socket contacts spaced away from and to the rear of said front surface and presenting a radially disposed surface generally perpendicular to said front surface, and d. insulating surfaces surrounding each of said contacts and preventing contact therewith except on said generally perpendicular surface from the rear of said front surface and arcuately with respect to the axis of said concentric slots, and B. a plug comprising: a. a front surface, and b. a pair of uprights adapted to fit through the wider openings of said slots, each of said uprights comprising portions of three widths, a first narrow portion narrower than the one of said slots into which it fits, a second wider portion fitting into the narrower of the two wider openings of the one of said slots into which it fits, and a third widest portion fitting into the widest of the two wider openings of the one of said slots into which it fits, said portions being spaced from the front surface of said plug in order of the narrowest, wider, and widest portions; and c. a pair of plug electrical contacts adapted to mate with said female contacts wiping against them in an axial motion toward said front surface of said socket when said wider portion of said uprights are fitted into the two narrower of the two wider openings of said slots.
Claim 3
Dependent Claim
36 words
An electrical quick connect connector as defined in claim 1 wherein said socket contacts are located adjacent the ends of said slots having the narrower openings, and said plug electrical contacts are mounted to said uprights.
Claim 4
Dependent Claim
63 words
An electrical quick connect power tap system as defined in claim 1, and B. a pair of mating ground contacts, one mounted to said plug and one mounted to said socket, said ground contacts comprising radially disposed surfaces adapted to mate before said plug and socket contacts mate and to wipe against each other during the wiping of said plug and socket contacts.
Claim 5
Dependent Claim
68 words
An electrical quick connect power tap system as defined in claims 1 or 2, wherein said socket contacts each present a terminating end portion closer to the front surface of said socket than said radially disposed surface, and each of said plug contacts presents a depending surface for engagement with the corresponding of said terminating end portions of said socket contacts at the end of said axial motion.
