Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to an electrical outlet receptacle, and, more particularly, to a modular electrical outlet receptacle.




2. Description of the Related Art




An office environment, as well as other work locations, often has several types of electrical and electronic equipment, such as computers, printers, photocopiers, communication equipment, facsimile machines, answering machines, etc. Each of these devices must be plugged into a circuit, which provides power from a power distribution system. Office environments often consist of large open areas of floor space, which are divided into separate and distinct areas by way of a wall panel system. The wall panel system can be modular and moved about with relative ease to change an office floor plan.




Modular electrical outlet receptacles may be included in the wall panel system, and provide flexibility in terms of system layout and inter-connectability with other components of the system. Typically a modular electrical receptacle includes at least one connector, which is adapted to interface with a corresponding connector on a wiring harness. The wiring harness typically includes a further connector at an opposing end thereof, which extends to another component of the system, such as another electrical receptacle. A problem with some modular electrical receptacles is the high cost involved to construct the receptacles. Conductors that traverse modular electrical receptacles must be strong enough to withstand repeated insertions and removals of electrical plugs.




Conductors may be formed by folding stamped metal, which serve to conduct power from an external source to a plug inserted into a portion of the formed conductor. Such conductors include a portion of folded metal forming a receiving slot for the insertion of a blade of the plug. Repeated insertions and removals of the blade of the plug may cause the receiving slot to deform.




What is needed in the art is a modular electrical receptacle with metal stamped and bent electrical conductors, which can retain their conductivity through, repeated insertions and retractions of electrical plugs.




SUMMARY OF THE INVENTION




The present invention provides a modular electrical receptacle including a housing, at least one plug-in connector and a face plate having at least two blade openings and an associated ground plug opening.




The invention comprises, in one form thereof, an electrical receptacle including at least one conductor member having at least one folded segment oriented to define a receiving socket and a housing having at least one lateral support feature, the at least one folded segment insertable into a corresponding one of the at least one lateral support features along an insertion axis, the at least one lateral support feature supporting the at least one folded segment in a direction transverse to the insertion axis, the housing including at least one blade opening, the at least one blade opening being disposed proximate to at least one of the receiving sockets.




An advantage of the present invention is that a modular electrical receptacle is provided with a conductor that is less expensive to form.




Another advantage is that the electrical conductor can be constructed from thinner material than would normally be used.




Yet another advantage is that the electrical conductor does not require added clips or springs to prevent deformation of the electrical contacts.

. Protrusions


24


are provided to co-act with similar provisions in housing


18


to provide separation of electrical conductors therein. Holes


26


are provided to allow connection of housing


18


to back plate


14


and thereby form an integral unit.




Conductor members


16


include electrical contacts


30


, folded segments


32


and


33


, folds


34


and receiving socket


36


. Conductor members


16


can be variously configured to provide electrical connections from one receiving opening


22


in one electrical connector


12


to another receiving opening


22


in another electrical connector


12


. Electrical contacts


30


provide for electrical interconnection between conductor members


16


and other conductor members or wiring harnesses, which are not shown. Electrical contacts


30


extend into electrical contact receiving openings


22


and are separated thereby. Folded segments


32


and


33


are each folded along a fold


34


to economically provide a receiving socket


36


between folded segments


32


and


33


. Folded segments


32


and


33


are folded along separate folds


34


, which are generally parallel with each other. Folded segments


32


and


33


, along with the portion of conductor member


16


between folds


34


, have a U-shaped cross-section. Receiving socket


36


is oriented and shaped to accommodate insertion of an electrical prong of an electrical plug, which is not shown. Alternatively, some conductor members


16


may connect power from one electrical connector


12


to another electrical connector


12


and not have a receiving socket


36


.

40


, a housing body


42


, contact separators


44


, assembly protrusions


46


and channel protrusions


48


. Faceplate


40


may be formed integral with housing body


42


thereby forming a single unitary construction. Faceplate


40


includes blade openings


50


and ground openings


52


. Blade openings


50


accommodate electrical prongs of a plug not shown. Ground opening


52


is shaped and oriented relative to blade openings


50


to accommodate a ground prong of a grounded plug.




Housing body


42


can be separate from faceplate


40


or alternatively be part of an integral monolithic construction with faceplate


40


. Contact separators


44


in housing body


42


separate conductor members


16


from each other. Assembly protrusions


46


in housing


18


accommodate the assembly of back plate


14


to housing


18


. Assembly protrusions


46


may either be inserted into holes


26


and extend there beyond for a terminating process or have a blind hole in assembly protrusion


46


to accommodate fasteners inserted through holes


26


.




Channel protrusion


48


is a generally U-shaped protrusion in housing


18


that accommodates folded segments


32


and


33


of conductor member


16


. Alternatively, one or more of the sides of channel protrusion


48


may be common with a surface of housing


18


, as illustrated by channel protrusion


48


A or channel protrusion


48


may take the form of a recess in housing


18


. Folded segments


32


and


33


are inserted into channel protrusion


48


such that the U-shaped folded segments


32


and


33


are inverted relative to the U-shaped channel protrusion


48


, as illustrated in FIG.


2


. Channel protrusions


48


serve as lateral support devices as they support folded segments


32


and


33


so that repeated insertions and retractions by an electrical plug through receiving socket


36


do not cause permanent deformation of folded segments


32


and


33


. The insertion of folded segments


32


and


33


into channel protrusions


48


, along an insertion axis, allow conductor member


16


to be made from a thinner material than would be possible without the support provided by channel protrusion


48


, thereby reducing the cost of the assembly. Channel protrusions


48


also mechanically support folded segments


32


and


33


, in a direction transverse to the insertion axis, which thereby enable receiving socket


36


to retain an acceptable amount of pressure on a plug blade inserted in receiving socket


36


. Channel protrusions


48


eliminate the need for a spring or clip, which may otherwise be needed to provide additional strength to folded segments


32


and


33


.
