Description




BACKGROUND OF THE INVENTION




The present invention relates to a wiring system used to provide electricity to individual work spaces created by a plurality of partitions subdividing an office area.




Open office space is typically partitioned to be used efficiently. By using a plurality of office panels or partitions, valuable space can be divided into individual cubicles providing employees with their own work spaces. The office panels are generally rectangular and may be provided with decorative surfaces. Each panel is provided with fasteners along the side edges which allow several adjacent panels to be attached to one another in orientations such as end to end or perpendicularly to one another.




Each panel is provided with a raceway which extends the length of each panel and is used to support a wiring system. The raceway may be located along the lower edge of the panel or near the middle of the panel at a height above the upper surface of a work surface such as a desk top. The wiring system is used to electrically connect adjacent panels while providing each panel with electricity. The wiring system includes receptacles mounted on a distribution harness (

FIGS. 4 and 5

) which, when supplied with electricity, provides each individual work station with receptacles for electrically operated equipment such as computers, lamps or the like. The receptacles are conventionally duplex receptacles in that each receptacle is provided with a pair of outlets.




Referring to

FIGS. 4 and 5

, one method of supplying electrical receptacles


40


to a plurality of individual work stations defined by office panels includes the use of buss or distribution harness


38


. Each end of distribution harness


38


is provided with connector


44


having a plurality of openings for receiving the socket ends of the receptacles


40


, jumper cables and power entry. Electrical current is supplied to the wiring system from either a ceiling power entry


61


, which would plug into one outlet of a receptacle, or a floor power entry


61


, which is plugged into connector


44


secured to one end


43


of distribution harness


38


(FIG.


5


). From power entry


61


, the electrical current travels through distribution harness


38


to receptacles


40


.




Receptacles


40


are electrically connected to distribution harness


38


which carries a plurality of jacketed wires or buss bars which are constructed from stamped metal (not shown). Distribution harness


38


typically carries eight or ten wires (although the present invention is not so limited) with each receptacle


40


being electrically connected to a ground wire, a neutral wire and a hot wire, the three wires defining a circuit. If desired, each receptacle


40


attached to harness


38


may be electrically connected to the same ground and neutral wires, however, receptacles


40


may be connected to different hot wires to define a second circuit. The first receptacle


40


is in engagement with connector


44


located at one end of distribution harness


38


and is connected to a combination of three wires of a first circuit. The second receptacle


40


, plugged into connector


44


at the opposite end of distribution harness


38


, may be electrically connected to the same or a second combination of three wires of a second circuit. By placing two receptacles on two separate circuits, overloading of a single circuit is prevented if, for example, more than one piece of equipment was plugged into receptacles


40


on that single circuit.




Distribution harness


38


is provided with elongated body portion


42


having ends


43


. One connector


44


is integrally attached to elongated body


42


at each end


43


(

FIG. 5

) and connectors


44


include sockets


46


having openings


47


, one pair of sockets protruding from each side of connector


44


. Socket


46


of connector


44


electrically connects with socket


48


located at one end of receptacle


40


while one socket


49


at the end of jumper cable


50


is electrically linked to socket


47


of connector


44


to define a pathway for electrical current between receptacle


40


, connector


44


and jumper cable


50


. One receptacle


40


is electrically attached to each socket


46


of connector


44


such that receptacles


40


may be mounted adjacent one another. A pair of receptacles


40


may be placed in one office panel being spaced the length of distribution harness


38


. One socket


49


of jumper cable


50


is secured to socket


47


of connector


44


while the second socket


49


of cable


50


is secured to a socket of a second connector disposed on distribution harness


38


in an adjacent office panel, thereby allowing distribution harnesses


38


of adjacent office panels to be electrically connected (FIG.


4


).




Once receptacles


40


are electrically joined with connectors


44


, receptacles


40


are secured to brackets


52


which are in turn fixed to distribution harness


38


(FIG.


5


). Tabs


54


extending from receptacle housing


56


are provided with apertures


58


which align with apertures


60


in brackets


52


. Fasteners are placed through aligned apertures


58


and


60


, securing receptacles


40


to buss or harness


38


. A plurality of wires or stamped buss bars (not shown) extend the length of distribution harness


38


between connectors


44


. All eight or ten wires are carried through connectors


44


to form contacts (not shown). Each receptacle


40


includes three wires (not shown) extending through receptacle


40


, connecting with connectors which align with each opening of the outlets in receptacle


40


. These wires have contacts at each end which provide means for electrically connecting to different combinations of ground, neutral and hot wires in connector


44


. By having each receptacle


40


associated with a separate circuit, overloading of a single circuit is prevented.




A problem with the current wiring system is the cost of the distribution harness. The distribution harness is a relatively large component of the system which requires that the raceway disposed at the bottom of the office panel be large enough to support the assembly. This adds to the cost of manufacturing and assembling the office panels when the wiring system is installed. Further, the size of the distribution harness limits the number of receptacles to two in each panel. The distribution harness is an expensive component of the wiring assembly which in turn increases the overall expense of supplying electricity to a plurality of work stations in an office. The assembly of the distribution harness assembly is time consuming due to the number of parts which must be assembled which again increases the cost of manufacturing. Furthermore, outlets in a duplex receptacle must be on the same circuit.




It is desired to provide a wiring assembly for providing office panels with a plurality of receptacles which eliminates the need for a distribution harness while being cost effective and easy to assemble.




SUMMARY OF THE INVENTION




The present invention relates to a wiring assembly for office panels in which the wires conventionally carried by the distribution harness are carried directly by the receptacle, thus eliminating the buss or distribution harness. The receptacle is preferably plugged into a quad connector and the wiring system is supplied power by a typical ceiling or floor power entry. Each receptacle picks off three wires from the eight or ten wires carried by the receptacle to provide the receptacle with electrical power. The receptacles may be wired to one circuit or a plurality of circuits to a partitioned area depending on how the area is being utilized. A jumper cable links one end of the first receptacle to one end of a second receptacle. The receptacles are wired in different circuits by being electrically connected to a different combination of three wires.




If desired, each outlet in a duplex or larger receptacle could be connected to a different circuit.




The advantages of eliminating the distribution harness include reducing the size of the wiring assembly as well as the cost of the assembly. The installation time required for placing the electrical assembly within the raceways of a plurality of office panels has also been reduced, which in turn lowers the expense of manufacturing. By wiring each receptacle or each outlet to be on a specific circuit, a work space may be provided with any number of circuits, from one to four in each panel depending on the needs of the office area.

of electrical assemblies


34


(

FIGS. 1 and 2

) to be exposed. Wiring assembly


30


includes a plurality of separate electrical assemblies


34


, generally two, which are spaced along each raceway


24


and thus panel


20


to provide electricity to the partitioned office space.




Referring to

FIGS. 2

,


6


and


7


, receptacles


36


have connectors or sockets


66


disposed at each end for electrically connecting to jumper cables


50


. Sockets


66


are male in construction and are received by female sockets


49


of jumper cables


50


. Referring to

FIG. 6

, when electrical assembly


34


is provided with a single receptacle


36


, a plurality of assemblies


34


are interconnected by jumper cables


50


. A series of receptacles


36


may be electrically connected by connecting socket


66


of one receptacle


36


with socket


49


of jumper


50


and socket


66


of a second receptacle


36


is received by the second socket


49


of jumper


50


. As usual, one end of the series of electrical assemblies is supplied with electrical current by power entry


61


or a jumper from an adjacent panel. When mounting receptacles


36


back-to-back to provide front and back surfaces


51


of panels


20


with electrical outlets or when panels


20


are disposed perpendicularly to one another as illustrated in

FIG. 3

, each assembly


34


further includes quad connector


62


module. Referring to

FIGS. 7 and 12

, quad connector


62


module includes surfaces


64


and


65


each having a pair of sockets


64




a


,


64




b


, and


65




a


,


65




b


protruding therefrom, respectively, and all electrically connected to each other. Sockets


64




a


and


64




b


are flush with edges


67


of quad connector


62


and are female in construction so as to electrically connect with male sockets


66


of receptacles


36


. Sockets


65




a


and


65




b


are male and are received in female sockets


49


of jumper cables


50


. Male sockets


65




a


and


65




b


are offset from edges


67


of quad connector


62


, being disposed inwardly from edges


67


. In assembly of wiring assembly


34


, female socket


49


of cable


50


is connected to one male socket


65




a


or


65




b


of connector


62


and one female socket


64




a


or


64




b


receives male socket


66


of receptacle


36


. Once cable


50


is electrically connected to quad connector


62


, resilient metal locking tabs


63


located on both sides of connector


62


engage a portion of socket


49


of cable


50


to prevent cable


50


from becoming dislodged from engagement with quad connectors


62


(

FIGS. 1

,


2


,


3


and


12


). It is understood that locking tabs


63


is only one method of locking cable


50


into engagement with quad connectors


62


and that any suitable method may be used.




As illustrated in

FIGS. 3 and 7

, quad connector


62


has the capability of supporting a pair of duplex receptacles


36


, with a receptacle


36


electrically connected to each socket


64




a


and


64




b


of quad connector


62


. The pair of sockets


65




a


and


65




b


of connector


62


are provided on the opposite side of quad connector


62


and are able to receive sockets


49


of two jumper cables


50


. For example, in one panel system shown in

FIG. 3

, one jumper cable


50




a


secures one electrical assembly


34




a


to a second electrical assembly


34




b


between two panels


20




a


and


20




b


that are disposed perpendicular to one another. A second jumper cable


50




b


, electrically connected to first assembly


34




a


, links first electrical assembly


34




a


to a third electrical assembly


34




c


located in a third panel


20




c


. Electrically connecting the above described panels


20




a


-


20




c


is possible because quad connector


62


allows two jumper cables


50




a


and


50




b


from two different panels


20




b


and


20




c


to be connected simultaneously. The distance between subsequent assemblies


34


is dependant upon the length of jumper cables


50


linking assemblies


34


as well as the size of panels


20


. Assemblies


34


are spaced to provide an adequate number of receptacles


36


to the work space and may include from a single electrical assembly


34


or a plurality of assemblies


34


as is depicted in the present embodiment.




Buss or distribution harness


38


of prior wiring systems disclosed in

FIGS. 4 and 5

is an expensive component used in the construction of wiring assembly


30


. The present invention eliminates distribution harness


38


by using receptacle


36


itself as the power distribution unit (

FIG. 8

) as will be described hereinbelow.




Referring more specifically to receptacle


36


shown in

FIGS. 8 and 10

, housing


68


includes a front plate


70


and rear plate


72


which are detachably joined by a plurality of integral pegs (not shown) and apertures


71


(FIG.


10


). The pegs extend perpendicularly from the inner surface of front plate


70


, aligning with and engaging and being welded or bonded to apertures


71


located in inner surface


98


of rear plate


72


, thereby interlocking front plate


70


and rear plate


72


. Housing


68


is constructed from a non-metallic material such as plastic including flame retardant polycarbonate, polystyrene, PVC, or ABS, by any suitable method including injection molding. Front plate


70


is provided with openings that define a pair of electrical sockets or outlets


74


in receptacle


36


, making receptacle


36


a duplex receptacle. Each outlet


74


includes elongated apertures or slots


76


and


78


which allow prongs of a conventional electrical plug of any electrically operated device (not shown) to connect to a neutral wire and a hot wire carried within housing


68


. Further provided to define grounded outlets


74


is a smaller, D-shaped aperture


80


disposed adjacent elongated slots


76


and


78


to enable an electrical connection between a ground prong of an electric plug and a ground wire in housing


68


.




Each receptacle


36


carries a plurality of active conductors or wires


96


which extend the length of receptacle housing


68


as discussed above (FIG.


8


). In a preferred embodiment, wires


96


have metal terminals


94


secured to both ends as shown in FIG.


9


. Wires


96


are relatively loose to permit crossing over of wires


96


. Wires


96


have an insulative jacket disposed thereon so as to protect against shorts in receptacle


36


when wires


96


are crossed as will be discussed below. Alternatively, conductors


96


may be stamped copper, cut to a specific length and shape necessary to create different circuits for receptacles


36


as will be described below. Crossing over of stamped copper conductors is not possible as they are not insulated from one another, thus contact between conductors


96


will create a short in receptacle


36


. A third method of wiring receptacle


46


includes the use of a printed circuit board.




Front plate


70


and rear plate


72


have ends


88


and


90


with grooves


82


and


84


located in plates


70


and


72


, respectively. When front plate


70


is assembled with rear plate


72


, ends


88


and


90


of each plate align such that grooves


82


and


84


define openings


86


in each end


88


and


90


of housing


68


(FIGS.


6


and


7


). Openings


86


are sized to received terminals


94


on wires


96


(FIGS.


8


-


10


), holding wires


96


in position within housing


68


. Once in place, terminals


94


are spaced from one another to define contacts in male sockets


66


at each end of receptacle


36


.




Projecting substantially perpendicularly from inner surface


98


of rear plate


72


are partitions and


102


which are longitudinally spaced from one another. Partitions are shorter than partitions


102


and are centrally disposed between ends


88


and


90


of rear plate


72


. A pair of partitions


102


are placed at each end


104


of partition , partitions and


102


being aligned along their longitudinal axes such that voids


106


exist between adjacent partitions and


102


. Voids


106


are of sufficient size for receiving metal electrical connectors or spades


108


and


109


so that connectors


108


and


109


fit tightly within voids


106


. Each electrical connector


108


and


109


includes a pair of female sockets


110


and


112


, respectively, which align with slots


76


and


78


for receiving the male prongs of an electrical plug. Electrical connector


114


is disposed between the longitudinal sets of spacers and


102


such that female sockets


116


of connector


114


align with D-shaped apertures


80


for receiving the male ground prongs of an electrical plug. It is understood that any orientation of alternative partitions may be used to receive connectors


108


,


109


,


114


whereby the connectors are suitably supported.




Connectors


108


,


109


, and


114


are constructed from a conductive metal which, when connected with conductors such as wires


96


and being in contact with the prongs of the electrical plug, provide a pathway for electrical current traveling through wiring system


30


to the electrically operated device. Sockets


110


,


112


and


116


are shaped such that the prongs of an electrical plug fit tightly in the sockets allowing for direct contact of the prongs and metal connectors


108


,


109


, and


114


. Sockets


110


and


112


of electrical connectors


108


and


109


, and sockets


116


of electrical connector


114


are integrally joined by bar


118


. Along the lower edge of each socket


110


,


112


, and


116


is a pair of barbs


122


. When electrical connectors


108


,


109


and


114


are electrically joined to one wire


96


, barbs


122


and bar


118


are folded around wire


96


(FIG.


8


). In order for an electrical connection to be made, pressure is applied to barbs


122


causing barbs


122


to pierce the insulative covering about wires


96


to, contacting the bare copper wire, thereby providing a conductive pathway for electrical current.




When manufactured, each receptacle


36


may be wired to be on a specific circuit. Wires


96


are manufactured to include a small amount of slack between terminals


94


so that they may be crossed over one another, enabling connection of wires


96


positioned within housing


68


furthest from stationary connectors


108


,


109


and


114


as illustrated in FIG.


8


. For example, in the case of the circuit provided in receptacle


36


which is illustrated in

FIG. 8

, hot wire


96




a


is positioned a distance from electrical connectors


114


. Therefore, in order for a connection to be made between conducting wire


96




a


and connector


114


, wire


96




a


must be crossed over hot wire


96




b


. Housing


68


of each receptacle


36


is provided with a marking (not shown) such as a number or letter so that the circuitry located within the receptacle may be easily identified. By having receptacles


36


wired on specific circuits, panels


20


of a work space may be provided with any number of circuits to prevent overloading of a single circuit. Each work space may be provided with receptacles


36


all wired on the same circuit such that different work spaces have different circuits. A second option is to place a pair of receptacles


36


on the same circuit in one panel


20


and receptacles


36


of a second circuit in a second panel


20


of the work space, thereby supplying a work space with two circuits. Further, each receptacle


36


in one panel


20


could be on different circuits to provide each panel with two circuits. Another alternative may be to provide each individual outlet


74


with a separate circuit, providing panel


20


with four different circuits, two circuits in each receptacle


36


.




In accordance with the present invention, receptacle


36


is wired to a specific circuit to allow for the different configurations of circuits in a work space as discussed above. Referring to

FIG. 11

, a schematic of one wiring scheme


30


is shown having ten wires electrically connected to six receptacles


36




a


-


36




f


. It is understood that the illustrated wiring schematic may be the same for the prior art wiring system including the distribution harness as it is for the present invention. A wiring system


30


having eight wires is similar to the ten wire system shown in

FIG. 11

having two fewer hot wires (

FIG. 10

) as will be discussed below. When wiring receptacles


36


, all ten wires


96


are carried by the receptacles with three wires


96


being “picked off,” or electrically connected to, by connectors


108


,


109


, and


114


to electrify outlets


74


. The remaining wires


96


simply pass through receptacles


36


without being electrically connected to connectors


108


,


109


and


114


. Electrical current is supplied to all ten wires with only three being used to supply electricity to outlets


74


. Sockets


49


of jumper cables


50


receive male socket


66


of receptacles


36


and carry current from one receptacle


36


to a second receptacle


36


. With the receptacles


36


themselves carrying wires


96


, distribution harness


38


used in previous systems is effectively eliminated.




Referring specifically to wiring system


30


of the schematic in

FIG. 11

, receptacle


36




a


is electrically connected to ground wire


126


, neutral wire


128


, and hot wire


130


, such that outlets


74


of receptacle


36




a


are on one circuit. Duplex receptacle


36




b


is mounted directly behind receptacle


36




a


in the manner illustrated in

FIG. 3

, creating one electrical assembly


34


having a pair of duplex receptacles


36


. Receptacle


36




b


is electrically connected to the same ground


126

and


156


, respectively. These receptacles


36


are shown carrying eight wires


96


. Although wires


96


are shown in

FIG. 10

as being straight, it is understood that wires


96


may be crossed over adjacent wires in order to come in contact with connectors

as first outlet


74


. Socket


110


′ of the second outlet


74


is connected to a second, different hot wire


160


by line


162


, thereby placing the second outlet


74


on a separate circuit from the first outlet


74


.




In assembling electrical assemblies


34


and thus wiring assembly


30


, each receptacle


36


is first wired to be on a given circuit. To do this, sockets


110


of connector


108


are secured to a hot wire


96


, sockets


112


of connector


109


are secured to a neutral wire


96


, and sockets


116


of ground connector


114


are secured to a ground wire


96


. Wires


96


need not be aligned parallel to one another, they may be crossed over one another to provide connection with connectors


108


,


109


and


114


to produce the desired circuit (FIG.


8


). Once receptacles


36


are produced, they are labeled with an identifying mark indicating the circuit for which the receptacle is wired. Receptacle


36


is electrically connected with jumper cable


50


(

FIG. 6

) and quad connector


62


(FIG.


7


). Depending on the number of circuits being provided to a work space, receptacles


36


are electrically connected to one another to create electrical assemblies


34


. Quad connector


62


is used if electrical assembly


34


is being provided with a pair of receptacles


36


mounted back-to-back or if panels


20


are oriented perpendicularly to one another. Male socket


66


of receptacle


36


is received by one female socket


64




a


and


64




b


of quad connector


62


to provide an electrical connection between quad connector


62


and receptacle


36


, forming electrical assembly


34


. A pair of adjacent electrical assemblies


34


are then joined by jumper cables


50


such that female socket


49


of cable


50


is received within one male socket


65




a


and


65




b


of connector


62


. Once fully inserted into quad connector


62


, locking tabs


63


lock onto jumper cable


50


to ensure full seating of male socket


65




a


and


65




b


of connector


62


into female socket


49


of cable


50


. One electrical assembly


34


is then supplied with power from ceiling or floor entry supply


61


(

FIGS. 6 and 7

) which supplies electricity to receptacles


36


via jumper cable


50


and quad connector


62


, thereby energizing electrical outlets


74


for use to supply electricity to any electrical equipment.




The sockets of jumper cables


50


and quad connectors


62


include individual connector terminals (not shown) that electrically contact terminals


94


to provide electrical continuity for each individual circuit.
