Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to electrical connectors, and, more particularly, to electrical connectors which couple with an electrical plug of a compressor.




2. Description of the Related Art




Compressor plugs are used to create an electrical connection to a terminal of a hermetic compressor. Such a compressor is typically employed in a refrigeration or air conditioning system.




Like in other situations where exposure to possible live electrical connections is possible, it is known to provide some sort of housing unit (akin to a junction box used in other situations) around the compressor plug as a preventive measure. Specifically, it has been known to use a housing unit that includes a fence member and a corresponding lid to enclose the compressor plug.




A problem associated with the electrical interconnects associated with the compressor and the compressor plug is that they tend to not be very robust mechanically. Consequently, these electrical interconnects can be broken, mechanically and thus electrically, rather easily.




In the embodiments of the known housing unit discussed above, the lid is mechanically associated with the compressor plug, either by contact or by an interconnection therebetween. As such, any impact upon the lid is transferred not only to the fence member but also to the compressor plug, thereby risking breakage of at least some of the electrical interconnects associated therewith. Additionally, the presence of the lid on the fence limits access to the compressor plug.




What is needed in the art is a housing member that can be readily held in place mechanically relative to the compressor plug, provide appropriate impact protection to the compressor plug and electrical interconnects associated therewith and still provide sufficient electrical shielding of those electrical interconnects.




SUMMARY OF THE INVENTION




The present invention provides a compressor plug assembly that includes a protective fence member that is readily connectable to a compressor plug and that helps protect the compressor plug from impact while still permitting access thereto.




The invention comprises, in one form thereof, a compressor plug cap assembly that includes a compressor plug and a fence member. The compressor plug has a first plug side face and an opposing second plug side face, the first plug side face configured for operative association with a compressor. The fence member substantially surrounds and is operatively connected to the compressor plug. The fence member is mounted relative to the compressor plug so as to substantially coextend with the first plug side face and to extend beyond the second plug side face. The fence member has a top fence side and a bottom fence side, each of the top fence side and the bottom fence side being substantially open.




The invention comprises, in another form thereof, a compressor plug cap assembly including a compressor plug, a fence member and a latch bail. The compressor plug has a diametrically opposed pair of arcuate receiver members associated therewith. The fence member is configured for mechanically receiving said compressor plug therein. The fence member at least partially surrounds the compressor plug. The fence member has a pair of receiver slots therein, the receiver slots being diametrically opposed to and generally parallel to each other. The fence member has a curved end portion, the curved end portion having a tang slot therein. The latch bail has a generally U-shaped configuration. The latch bail has a pair of bail ends, each bail end operatively mating with and pivotably mounted within one receiver slot. Each bail end has a bail extension portion extending toward the compressor plug. Each bail extension portion is received within a respective arcuate receiver member. The latch bail has a rounded mid-section, the latch bail including a tang extension thereat. The tang extension operatively fits in the tang slot of the fence member.




The invention comprises, in yet another form thereof, a compressor plug cap assembly that includes a compressor plug and a fence member. The compressor plug has a diametrically opposed pair of plug tabs extending therefrom. The fence member is configured for mechanically receiving the compressor plug therein. The fence member at least partially surrounds the compressor plug. The fence member has a diametrically opposed pair of receiver notches therein, each receiver notch receiving a corresponding plug tab therein.




An advantage of the present invention is that the fence member of the compressor plug assembly is configured for protecting the compressor plug from impact while still promoting easy access thereto.




Another advantage is that simple yet robust mechanical connections are used to hold together the elements of the compressor plug assembly.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to the drawings, and more particularly to

FIG. 1

, there is shown a compressor plug cap assembly


20


which generally includes a compressor plug


22


, fence member


24


and latch bail


26


.




Compressor plug


22


is used in association with a compressor (not shown) of a household appliance (e.g., a refrigerator, freezer, etc.). The body of compressor plug


22


is typically made of an elastomeric material (such as the one sold under the trade name of Santopreme 253-36). Compressor plug


22


includes a plug end


28


(

FIG. 2

) and a conductor out-feed end


30


. Female receptacle members


32


within plug end


28


facilitate an electrical connection between an electrical connector (not shown) of the compressor, while out-feed conductors


34


of conductor out-feed end


30


permit a connection with a power source (not shown). Compressor plug


22


has a first side face


36


(best seen in

FIG. 3

) and an opposing second side face


38


. Access to female receptacle members


32


is available via first side face


36


.




Additionally, generally orthogonal to both out-feed conductors


34


and second side face


38


, compressor plug


22


has a diametrically opposed pair of substantially arcuate receiver members


40


(

FIGS. 3

,


4


) associated therewith. Arcuate receiver members


40


, while shown to be generally semicircular and to be integral with compressor plug


22


in this embodiment, instead could take other arcuate forms (such as circular, oval or semi-oval) and/or could be attached to (as opposed to integral with) compressor plug


22


.




Fence member


24


is configured for mechanically receiving compressor plug


22


therein in a manner such that fence member


24


at least partially surrounds compressor plug


22


. Fence member


24


is advantageously composed of cold-rolled steel or other material that permits fence member


24


to withstand a dropped steel ball test (i.e., impact resistant). Fence member


24


has a pair of receiver slots


42


therein (as best seen in FIGS.


4


and


5


), receiver slots


42


being diametrically opposed to and generally parallel to each other. Each receiver slot


42


is substantially L-shaped, having a primary slot portion


44


and a shorter secondary slot portion


46


. Fence member


24


has a curved end portion


48


and a second end portion


50


opposite curved end portion


48


. Curved end portion


48


has a tang slot


52


therein, while second end portion


50


has an out-feed receptor slot


54


therein, out-feed receptor slot


54


receiving conductor out-feed end


30


of compressor plug


22


therein. In this embodiment out-feed receptor slot


54


is nearly a complete circle with an upper opening (not labeled) to permit insertion and, yet, promote retention of conductor out-feed end


30


therein.




Second end portion


50


is further provided with a sizing notch


56


below and in communication with out-feed receptor slot


54


. As such, the presence of sizing notch


56


allows out-feed receptor slot


54


to be opened to greater than its normal width, thereby easing insertion of conductor out-feed end


30


therein. Additionally, if conductor out-feed end


30


is wider than out-feed receptor slot


54


, a force fit (e.g., a snap fit) therebetween will result, thereby aiding in the retention of compressor plug


22


within fence member


24


.




Fence member


24


coextends with first side face


36


of compressor plug


22


, fence bottom


57


of fence member


24


and first side face


36


thereby being configured for adjoining a compressor (not shown) to which compressor plug


22


is to be electrically connected. Meanwhile, fence member


24


extends beyond second side face


38


of compressor plug


22


. The resulting gap between fence top


58


of fence member


24


and second side face


38


of compressor plug


22


effectively protects both female receptacle members


32


within plug end


28


and the electrical connector of the compressor from various objects that may strike (e.g, such as from falling) fence member


24


that would otherwise impact directly on compressor plug


22


if such a gap were to not exist. Such a degree of impact protection is achieved without placing a lid upon fence member


24


, thereby permitting relatively ready accessibility to compressor plug


22


. Fence bottom


57


and fence top


58


are substantially open, thereby permitting easy access into fence member


24


.




Latch bail


26


has a generally U-shaped configuration (as seen from

FIGS. 1

,


4


and


6


) and usually is formed of a bent wire. Latch bail


26


has a pair of bail ends


60


, each bail end


60


operatively mating with and pivotably mounted within a respective receiver slot


42


in fence member


24


. Each bail end


60


has a bail end ear


62


, bail end ear


62


being initially receivable in a respective primary slot portion


44


of receiver slot


42


in fence member


24


and then pivotably receivable within a respective secondary slot portion


46


thereof. As seen from

FIG. 1

, the combined configuration of each bail end ear


62


and each L-shaped receiver slot


42


helps to retain latch bail


26


in the locked position, shown in

FIG. 1

, within fence member


24


.




Each bail end


60


has a bail extension portion


64


extending toward the other of bail ends


60


and, when latch bail


26


is assembled with the rest of compressor plug cap assembly


20


, each bail extension portion


64


extends toward compressor plug


22


. Specifically, each bail extension portion


64


is inserted and pivotably received within a respective arcuate receiver member


40


of compressor plug


22


.




Latch bail


26


has a rounded mid-section


66


and has a tang extension


68


at rounded mid-section


66


thereof. Tang extension


68


operatively fits in tang slot


52


of fence member


24


. Such an operative fit helps retain latch bail


26


and, via bail extension portions


64


, compressor plug


22


within fence member


24


.




Latch bail


26


is springably expanded, positioned relative to compressor plug


22


and then released to allow insertion of each batch extension portion


64


in respective arcuate receiver member


40


. Latch bail


26


, via the pivotable connection between each batch extension portion


64


and respective arcuate receiver member


40


, is positioned so as to be substantially orthogonal to compressor plug


22


. Compressor plug


22


is now inserted into fence member


24


, conductor out-feed end


30


snapping into out-feed receptor slot


54


in second end portion


50


and each bail end ear


62


slidably fitting into primary slot portion


44


of respective receiver slot


42


within fence member


24


. Locking of latch bail


26


relative to fence member


24


is achieved by rotating latch bail


26


toward a parallel position with respect to compressor plug


22


. At the end of that rotation, tang extension


68


of latch bail


26


engages tang slot


52


in fence member


24


and each bail end ear


62


moves into secondary slot portion


44


of respective receiver slot


42


.




In an alternate embodiment shown in

FIGS. 7-10

, compressor plug cap assembly


80


includes a compressor plug


82


and a fence member


84


.




Compressor plug


82


includes a plug end


86


and a conductor out-feed end


88


. Female receptacle members


90


within plug end


86


facilitate an electrical connection between an electrical connector (not shown) of the compressor, while out-feed conductors


92


of conductor out-feed end


88


permit a connection with a power source (not shown). Compressor plug


82


has a first side face


94


and an opposing second side face


96


. Access to female receptacle members


90


is available via first side face


94


.




Additionally, compressor plug


82


has a diametrically opposed pair of tab members


98


associated therewith, each tab member


98


located on plug end


86


at a position generally orthogonal to out-feed conductors


92


and below second side face


96


. Each tab member


98


extends angularly upward toward second side face


96


.




Fence member


84


is configured for mechanically receiving compressor plug


82


therein in a manner such that fence member


84


at least partially surrounds compressor plug


82


. Fence member


84


has a pair of tab receiver apertures


100


therein (as best seen in FIGS.


4


and


5


), tab receiver apertures


100


being diametrically opposed to each other and positioned so as to receive a corresponding tab member


84


of compressor plug


82


therein.




Fence member


84


has a curved end portion


102


and an opposite second end portion


104


. Second end portion


104


has an out-feed receptor slot


106


therein, out-feed receptor slot


106


receiving conductor out-feed end


88


of compressor plug


82


therein. In this embodiment, out-feed receptor slot


106


is substantially orthogonal (i.e., rectangular in shape).




Second end portion


104


is further provided with a sizing notch


108


below and in communication with out-feed receptor slot


106


. As such, the presence of sizing notch


108


allows out-feed receptor slot


106


to be opened to greater than its normal width, thereby easing insertion of conductor out-feed end


88


therein. Additionally, by configuring conductor out-feed end


88


to be wider than out-feed receptor slot


106


(in its unexpanded, relaxed state), a force fit therebetween can be achieved, thereby aiding in the retention of compressor plug


82


within fence member


84


.




Fence member


84


coextends wit first side face


94


of compressor plug


82


, fence member


84


and first side face


94


thereby being configured for adjoining a compressor (not shown) to which compressor plug


82


is to be electrically connected. Meanwhile, fence member


84


extends beyond second side face


96


of compressor plug


82


. The resulting gap between fence top


110


of fence member


84


and second side face


96


of compressor plug


82


effectively protects both female receptacle members


90


within plug end


86


and the electrical connector of the compressor from various objects that may strike (e.g., such as from falling) fence member


84


that would otherwise impact directly on compressor plug


82


if such a gap were to not exist. Such a degree of impact protection is achieved without placing a lid upon fence member


84


, thereby permitting relatively ready accessibility to compressor plug


82


.




Compressor plug


82


is inserted into fence member


84


. In the process, conductor out-feed end


88


snaps into out-feed receptor slot


106


in second end portion


104


and each tab member


98


snaps into respective tab receiver aperture


100


within fence member


84


. As such, compressor plug cap assembly


80


offers the advantage of quick and easy assembly.
