Abstract
A combination electrical connector and electrical switch comprises a three-sided shroud portion formed upon the electrical switch housing so as to ensure proper electrical connection of the electrical switch and electrical connector in a polarized manner. The electrical connector comprises electrical contacts which include insulation displacement portions for electrical connection to external wiring, and blade reception portions for electrical connection to blade members of the electrical switch wherein all electrical connections are solderless. The blade reception portions of the contacts comprise oppositely disposed, flexible members which are integrally connected together and which are able to self-generate the necessary forces to engage and retain the blade members of the electrical switch.
Description




FIELD OF THE INVENTION




The present invention relates generally to electrical switch mechanisms and electrical connector components, and more particularly to a new and improved low-profile combination electrical switch and connector assembly which facilitates easy assembly of the switch mechanism and connector component, wherein the connector component and switch mechanism are connected together in a properly oriented or polarized manner, and wherein the electrical contacts disposed within the electrical connector not only facilitate easy connection to external wires through means of insulation displacement techniques, but in addition, the electrical contacts are self-supporting and self-generate requisite forces for electrical connection to tab members of the switch mechanism.




BACKGROUND OF THE INVENTION




Switch mechanisms and operatively associated electrical connector components are often mounted upon support panels, walls, or the like so as to remotely control electrical appliances, lighting fixtures, or other electrical equipment. Space for accommodating the electrical switch mechanisms and their operatively associated electrical connector components, however, is often limited, confined, or simply not readily accessible whereby it becomes necessary to minimize or optimize the component or hardware dimensions. In addition, it is desirable that the electrical switch mechanism and the electrical connector component be able to be electrically connected to, and when required, electrically disconnected from, each other in a relatively simple, properly oriented, and cost-effective manner, preferably by means of non-soldered plug-in and/or insulation displacement type connections. Accordingly, replacement or exchange of the assembly components would be facilitated and expedited. Unfortunately, such an electrical connector and switch mechanism assembly does not presently exist in the current state of the art.




A need therefore exists in the art for a new and improved combination electrical switch mechanism and electrical connector assembly wherein the electrical switch mechanism and the electrical connector has a compact profile enabling the same to be mounted within confined or restricted spatial environments upon support panels, walls, or the like, wherein the electrical switch mechanism and electrical connector can be readily and easily assembled or electrically connected together in a properly oriented or polarized manner by means of solderless connections, and wherein further, the electrical contacts disposed within the electrical connector not only can provide electrical connections to external wiring by means of solderless insulation displacement structure formed upon first ends of the contacts, but in addition, second opposite ends of the contacts can mate with tab contact members of the switch mechanism by means of contact portions which are self-supporting and which self-generate the necessary forces for mating with the tab contact members of the switch mechanism without support from the surrounding housing enclosure.




OBJECTS OF THE INVENTION




Accordingly, it is an object of the present invention to provide a new and improved combination electrical switch mechanism and electrical connector assembly.




Another object of the present invention is to provide a new and improved combination electrical switch mechanism and electrical connector assembly which has a compact profile for facilitating mounting of the assembly within spatially confined or restricted areas upon support panels, walls, or the like.




An additional object of the present invention is to provide a new and improved combination electrical switch mechanism and electrical connector assembly wherein the electrical switch mechanism and electrical connector are provided with mating structure such that the switch mechanism and connector can only be connected together in a predetermined polarized manner.




A further object of the present invention is to provide a new and improved combination electrical switch mechanism and electrical connector assembly wherein the electrical connections between the electrical switch mechanism and the electrical connector, and between the electrical contact members of the connector and external wiring connected thereto are accomplished in a solderless manner, and wherein the electrical contacts of the connector are self-supporting and self-generating in connection with forces required for mating with the tab members of the electrical switch mechanism.




SUMMARY OF THE INVENTION




The foregoing and other objectives are achieved in accordance with the teachings and principles of the present invention through the provision of a new and improved combination electrical switch mechanism and electrical connector assembly which comprises an electrical connector having electrical contacts disposed therein, and a switch mechanism which includes a plurality of dependent tab members for insertion within the electrical connector for mating with the contact members of the electrical connector in a friction-fit solderless manner. The switch mechanism also comprises a three-sided shrouded housing whereby the switch mechanism can only be mated with the electrical connector in a predetermined polarized manner. The contact members of the electrical connector also have insulation displacement portions for terminating external wiring therein in a solderless manner, and the contact members are self-supporting so as not to require external support from the electrical connector housing. The contact members also self-generate the requisite forces required for mating with the dependent tab members of the switch mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, and more particularly to

FIGS. 1 and 2

thereof, a first embodiment of the new and improved combination electrical switch mechanism and electrical connector assembly is disclosed, is generally indicated by the reference character


10


, and is seen to comprise the electrical switch mechanism


12


and the electrical connector


14


. The switch mechanism


12


may comprise, for example, a conventional rocker switch element


16


which is mounted within a switch plate


18


wherein the plate


18


is adapted to be disposed externally upon a support panel, wall, plate, or the like, not shown, when the switch mechanism


12


is mounted upon the support panel, wall, plate, or the like, not shown. In order to facilitate the mounting of the switch mechanism


12


upon the support panel, plate, wall, or the like, not shown, the switch mechanism


12


further comprises a housing


20


which has a configuration which is substantially that of a rectangular parallelepiped, and a pair of flexible mounting fingers


22


is mounted upon respective opposite ends


24


of the switch housing


20


in a cantilevered manner. Each one of the flexible mounting fingers


22


is integrally mounted at its lower end portion upon a lower end region of the switch housing


20


, while an upper distal end portion


26


of each finger


22


is disposed at an elevational level which is below the lower edge of switch plate


18


so as to define a space


28


having a predetermined dimension. The dimension of space


28


is adapted to substantially match the thickness dimension of the support panel, wall, plate, or the like, not shown, upon which the combination switch mechanism and electrical connector


10


is to be mounted in a snap-fitted manner.




In particular, the switch mechanism


12


is adapted to be inserted downwardly through an aperture, not shown, defined within the support panel, plate, wall, or the like, also not shown, whereby the flexible fingers


22


will be forced inwardly, from their illustrated positions toward the switch mechanism housing


20


, by the side walls of the support panel, plate, wall, or the like, not shown, which define the aperture, not shown. When the upper distal end portions


26


of the fingers


22


pass beneath the lower surface of the support panel, wall, plate, or the like, not shown, the fingers


22


will expand outwardly or snap back to their illustrated positions so as to lockingly engage the undersurface of the support panel, plate, wall, or the like, whereby the switch mechanism


12


will be fixedly mounted upon the support panel, wall, plate, or the like, not shown.




With reference continuing to be made to

FIGS. 1 and 2

, the switch mechanism


12


is seen to further comprise a plurality of dependent blade-type contact members


30


extending downwardly from the bottom portion of the switch housing


20


, and a three-sided shroud


32


integral with the end walls


24


of the switch housing, and the rear wall, not shown, of the switch housing


20


, and depending downwardly so as to surround the dependent blade members


30


upon three sides thereof, leaving the fourth front side open, and also define a substantially enclosed space


34


. The electrical connector


14


is seen to comprise an electrical connector contact housing


36


which has the configuration of a rectangular parallelepiped and which is supported upon a lower base or foundation


38


. The upper surface


40


of the electrical connector housing


36


is seen to comprise a plurality of apertures


42


for receiving or accommodating insertion or reception of the dependent blade members


30


of the switch mechanism


12


, and the apertures


42


connect to interior hollow portions of the housing


36


within which electrical contact portions are disposed, as will be more fully disclosed and explained hereinafter, for mating electrical connection with the blade members


30


of the switch mechanism


12


when the switch mechanism


12


and electrical connector


14


are mated together as a result of the switch mechanism


12


being moved downwardly relative to the electrical connector


14


in accordance with the arrow D or as a result of the electrical connector


14


being moved upwardly relative to the switch mechanism


12


in accordance with the arrow U.




Opposite end walls


44


of the dependent shroud are provided with apertures


46


, and opposite end walls


48


of the connector housing


36


are provided with detents


50


which are adapted to be lockingly snap-fitted within the apertures


46


of the shroud end walls


44


when the switch mechanism


12


is mated with the electrical connector


14


. As can best be appreciated from

FIG. 2

, when the electrical switch mechanism


12


is mounted upon or mated with the electrical connector


14


, the switch housing


20


is disposed atop the connector housing


36


and the three-sided shroud


32


of the switch mechanism


12


substantially encloses the opposite end walls


48


,


48


and rear wall, not shown, of the electrical connector housing


36


. The bottom surface portions of the shroud end walls


44


,


44


, as well as the bottom portion of its rear wall


52


, are supported upon the base or foundation


38


of the connector


14


. The electrical connector


14


is also provided with an auxiliary housing portion


53


which is integrally formed upon and projects forwardly of the connector housing


36


. Auxiliary housing portion


53


is provided for facilitating insertion of the electrical connector contacts into the electrical connector


14


wherein the electrical connector contacts provide electrical connection between external wiring and the contact blade members


30


of the switch mechanism


12


. In addtition, as can be further appreciated, due to the interactive structure of the switch mechanism


12


and the electrical connector


14


, and in particular, the provision of the three-sided shroud portion


32


upon the switch mechanism


12


as well as the provision of the auxiliary housing portion


53


upon the electrical connector


14


, the switch mechanism


12


must be disposed in a uniquely required orientation when the switch mechanism


12


is to be mounted upon the electrical connector


14


whereby, in effect, a polarized connection is established or defined between the switch mechanism


12


and the electrical connector


14


so as to ensure proper mounting or mating of such components with respect to each other.




In connection with the electrical connector contacts, the electrical connector


14


is adapted to have inserted therein three electrical connector contacts for electrical mating with the three dependent blade members


30


of the switch mechanism. Accordingly, with additional reference being made to

FIGS. 3 and 4

, the new and improved electrical connector contacts are disclosed and are generally indicated by the reference character


54


. It is noted that

FIG. 3

discloses the electrical contact


54


as disposed in its normal orientation for insertion within the electrical connector


14


, while

FIG. 4

discloses the electrical contact


54


as disposed in an inverted mode so as to clearly illustrate additional features of the contact


54


which are not apparent from FIG.


3


. Accordingly, orientation terminology will be used in connection with the description of the contact


54


as shown in

FIG. 3

, although such terminology may not be accurate with respect to the disclosure of

FIG. 4

due to the inversion of the contact


54


as disclosed in FIG.


4


as compared to its orientation in

FIG. 3

, however, the component parts of the contact


54


as shown in

FIG. 4

which correspond to the same parts of the contact


54


as shown in

FIG. 3

will be designated by the same reference characters for clarity and consistency.




More particularly, as shown in

FIG. 3

, each one of the electrical connector contacts


54


is seen to comprise, as considered from the viewpoint of the disposition of the contact


54


when the same is mounted within the electrical connector


14


, a forwardly disposed insulation displacement contact portion


56


for electrical connection to external wiring and a rearwardly disposed blade-engaging contact portion


58


for electrical connection to the blade members


30


of the switch mechanism


12


. The insulation displacement contact portion


56


is seen to comprise a pair of vertically spaced upper and lower insulation displacement contact members


60


,


62


. The contact members


60


,


62


are connected to each other at left side or edge portions thereof, again as considered from the viewpoint of the disposition of the contacts


54


when the contacts


54


are disposed or mounted within the electrical connector


14


, by means of a vertically disposed wall member


64


, and the right side portions of the contact members


60


,


62


define free edge portions


66


,


68


. As will be discussed shortly hereinafter, the upstanding wall member


64


and the free edge portions


66


,


68


of the contacts


54


help serve to support the contacts


54


within the electrical connector


14


. In addition, substantially central portions of the contact members


60


,


62


are of course provided with slotted regions


70


,


72


which are provided for achieving insulation displacement or insulation stripping procedures in connection with external wires, not shown, to be electrically connected to the electrical connector contacts


54


in accordance with well-known techniques.




The blade-engaging contact portion


58


of each one of the electrical contacts


54


is seen to comprise a left side wall member


74


which, in effect, is an integral extension of the upstanding side wall member


64


of the insulation displacement contact portion


56


, and a floor member


76


which is integrally connected at its left edge portion to the lower end of the upstanding wall member


74


. A first downwardly extending blade-engaging contact member


78


is integrally connected to the upper end of the upstanding wall member


74


, and a second upwardly extending blade-engaging contact member


80


is integrally connected to the right edge portion of the floor member


76


. It is seen that the first blade-engaging contact member


78


is provided with a vertically central, longitudinally extending planar portion


82


, and the second blade-engaging contact member


80


is similarly provided with a vertically central, longitudinally extending planar portion


84


which is transversely spaced from the planar portion


82


of contact member


78


so as to permit insertion of a respective one of the blade members


30


of the switch mechanism


12


therebetween. The provision of the planar surfaces or portions


82


,


84


establish surface-to-surface contact with the blade member


30


, and in order to facilitate insertion of the blade member


30


into the space or channel


86


defined between the planar portions


82


,


84


, the upper end of the contact member


78


is provided with an outwardly inclined or divergent entrance portion


88


and the upper end of the contact member


80


is similarly provided with an outwardly inclined or divergent entrance portion


90


.




It is to be appreciated that both of the blade engaging contact members


78


,


80


are respectively freely mounted upon the upstanding wall and floor members


74


,


76


so as to be resiliently flexible, and in this manner, the contact members


78


,


80


are self-supporting and self-generate the necessary forces in the transverse or lateral direction so as to properly engage a respective one of the blade members


30


when the blade member


30


is inserted into space or channel


86


between the contact portions


82


,


84


. In order to permit the blade-engaging contact members


78


,


80


to be so flexibly disposed, it is noted that the forward end portions


92


,


94


of the contact members


78


,


80


are longitudinally or axially spaced as at


96


from rear edge portions


98


,


100


of the insulation displacement contact members


60


,


62


. In a similar manner, rear end portions


102


,


104


of the contact members


78


,


80


are longitudinally or axially recessed forwardly as at


106


,


108


from the respective rear edge surface portions


110


,


112


of the upstanding wall and horizontal floor members


74


,


76


such that when the electrical contacts


54


are mounted within the electrical connector


14


, the rear end portions


102


,


104


of the contact members


78


,


80


will not engage or abrade the rear internal wall surface of the electrical connector housing


36


. It is also to be appreciated that all electrical connections characteristic of the combination electrical switch and connector assembly


10


of the present invention, that is, between the external wires, not shown, and the insulation displacement contacts


60


,


62


, and between the blade members


30


and the contact members


78


,


80


are entirely solderless.




With reference again being made to

FIGS. 1 and 2

, the electrical connector


14


, comprising the primary connector housing


36


and the auxiliary connector housing


53


comprises, for example, four upstanding wall members


114


so as to define, in effect, three electrical contact sockets


116


therebetween which extend substantially the full depth of the electrical connector


14


and within which the electrical contacts


54


will be disposed. More particularly, a horizontally disposed or extending channel


118


is defined within a vertically central portion of each left-side interior wall surface of each upstanding wall member


114


, and in a similar manner, a pair of vertically spaced horizontally extending channels


120


,


122


are defined within vertically central portions of each right-side interior wall surface of each upstanding wall member


114


. As can therefore be appreciated, when the electrical contacts


54


are to be mounted within the electrical connector


14


, electrical contact vertical wall member


64


/


74


will be disposed within the electrical connector channel


118


while the free edge portions


66


,


68


of each contact


54


will be respectively disposed within the channels


120


,


122


of the connector


14


.




In order to lock each one of the contacts


54


within its respective socket


116


, a rearward portion of each one of the vertical walls defining each channel


118


is provided with an aperture, not shown, for receiving a locking tab


124


which is provided upon the vertical wall member


74


of each contact


54


as best seen in FIG.


4


. In addition, each one of the sockets


116


is also provided with an internal upstanding boss or the like, not shown, upon which the floor member


76


of each contact


54


is supported so as to support the rearward portion of each contact


54


, particularly in connection with the resistance to any downward force which may be impressed thereon when the blade members


30


of the switch mechanism


12


are being inserted into the spaces


86


of the contact members


54


so as to be electrically engaged with the flexibly movable contact portions


78


,


80


. Lastly, each one of the upstanding wall members


114


has integrally formed upon forward end portions thereof, at upper and lower vertically spaced levels, a plurality of oppositely disposed tab members


126


which serve to retain the external wires, not shown, which are to be inserted into the sockets


116


for electrical connection to the insulation displacement contact members


60


,


62


.




With reference now being made to

FIGS. 5



a


,


5




b


, and


6


, a second embodiment of the new and improved combination electrical switch mechanism and electrical connector assembly is disclosed and is generally indicated by the reference character


210


. It is to be noted that the second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


as disclosed within

FIGS. 5



a


,


5




b


and


6


is structurally and operationally similar to the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

, except as will be specifically noted hereinafter, and accordingly component parts of the second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


as disclosed within

FIGS. 5



a


,


5




b


and


6


which are similar to corresponding parts of the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

will be designated by corresponding reference characters except that the reference characters will be within the


200


and


300


series. In addition, with respect to those component parts of the second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


as disclosed within

FIGS. 5



a


,


5




b


and


6


whose function is apparently substantially the same as in the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed


10


within

FIGS. 1 and 2

, a detailed description of such component parts and their functions is deemed unnecessary and therefore will not be provided.




More particularly, then, it is seen that the major difference between the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

and the second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


as disclosed within

FIGS. 5



a


,


5




b


and


6


resides in the fact that, in lieu of the auxiliary housing portion


53


projecting forwardly from a side portion of the electrical connector housing


36


as was the case with the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

, the auxiliary housing portion


253


of the electrical connector


214


projects downwardly from the bottom, base, or foundation portion


238


of the electrical connector housing


236


. In this manner, the contact housing


236


is disposed atop the auxiliary housing portion


253


as opposed to the housings being disposed in effect in a side-by-side arrangement as was the case of housing


36


and auxiliary housing


53


of the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

. In this manner, it is also seen that the wires to be mated with the electrical contacts disposed within the auxiliary housing portion


253


will extend horizontally, as opposed to vertically, thus permitting the second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


disclosed within

FIGS. 5



a


,


5




b


and


6


to be used within applications which may require orientations which are different from those afforded by the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

.




Continuing further, it is seen that the auxiliary housing portion


253


comprises four upstanding wall members


314


which are disposed parallel to each other in a mariner similar to the disposition of the upstanding wall members


114


of the auxiliary housing portion


53


of the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


as disclosed within

FIGS. 1 and 2

, however, in lieu of the horizontally disposed channels


118


,


120


,


122


extending rearwardly from forwardly disposed faces of the upstanding wall members


114


, the upstanding wall members


314


are respectively provided with vertically disposed channels


318


,


320


,


322


which extend upwardly from lower or bottom surfaces


315


of the upstanding wall members


314


as best seen in

FIG. 5



b


. It is to be further appreciated that the same electrical contacts


54


shown in

FIGS. 3 and 4

, and previously used in connection with the combination electrical switch mechanism and electrical connector assembly


10


, are likewise to be used in connection with the combination electrical switch mechanism and electrical connector assembly


210


except that the electrical contacts


54


will be inserted vertically upwardly within the channels


318


,


320


,


322


as opposed to horizontally as was the case when the electrical contacts


564


were inserted within the channels


118


,


120


,


122


of the combination electrical switch mechanism and electrical connector assembly


10


. Accordingly, it will be further appreciated that when the electrical switch blade members


230


are to be mated with the electrical contacts


54


, in lieu of the tip portions


231


of the blade members


230


being inserted between the entrance portions


88


,


90


of the electrical contacts


54


, the tapered tip portions


231


of the blade members


230


will be inserted between the end faces of the electrical contact planar portions


82


,


84


. It is lastly to be appreciated that the polarizing feature characteristic of the first embodiment of the combination electrical switch mechanism and electrical connector assembly


10


is also present within second embodiment of the combination electrical switch mechanism and electrical connector assembly


210


as comprising the three-sided shroud


232


which includes side walls


244


and rear wall


252


. In addition, as is also clear from

FIGS. 5



a


and


5




b


, the apertures


242


are laterally offset backwardly toward the rear vertical wall surface


243


of the electrical connector housing


236


and away from the front vertical wall surface


245


of the electrical connector housing


236


, and similarly for the blade member


230


disposed within the electrical switch housing


220


as being offset laterally rearwardly away from the front wall


221


of the housing


220


and toward the rear wall


252


of the housing shroud


232


.




Thus, it may be seen that in accordance with the principles and teachings of the present invention, a new and improved combination electrical switch mechanism and electrical connector assembly has been developed wherein the assembly has a relatively low profile and wherein all electrical connections between the switch mechanism and the electrical connector, as well as between the electrical connector and external wiring, is achieved through means of solderless connections. In addition, the connection between the switch mechanism and the electrical connector is polarized such that the components can only be connected to each other in a predetermined proper mode or orientation. Lastly, the electrical contacts disposed within the electrical connector are self-supporting and self-generate the necessary forces for properly mating with the blade members of the switch mechanism.




Obviously, many variations and modifications of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described herein.
