The connector includes first, second, and third contacts positioned within an insulating housing that has at least three cavities parallel to one another. Each contact is positioned within the housing so that the connector is configured to receive external conductors and the associated switch terminals.
Description




BACKGROUND OF THE INVENTION




The present invention relates generally to an insulated connector, and more particularly to insulated connectors for use with switches. The connector may be used with sub-miniature switches, and more particularly, with push button sub-miniature switches.




Switches are well known and can be used in various electro-mechanial devices, such as video games, vending machines, and control apparatuses. Push button switches are one type of switch that can incorporate normally open, normally closed and common terminals. Push button switches are often used in vending machines, video games, slot machines and the like. These switches can be used to allow a user to operate a computer animated figure in a video game, to order a refreshment beverage in a vending machine, or to play a ‘hand’ in a slot machine.




Many of these devices have a limited amount of space for switch placement, and the switches are generally part of an electrical circuit that requires external conductors to remain in electric contact with the switch terminals. Typically, the conductors are soldered onto the terminals of the switches, and the ends of the conductors are terminated at the terminals. It is imperative that the conductors are soldered onto the appropriate switch terminals to allow for proper switch functionality. Because space within the devices is limited, this process is very tedious and can result in manual error during installation.




To protect the switch or adjacent components from early burn out, a circuit element, such as a diode, is often placed across two of the switch terminals. Typically, circuit element leads are soldered onto the switch terminals. It is crucial that the circuit element leads are connected onto the appropriate switch terminals for proper switch functionality. Again, because space within the devices is limited, this process is tedious and can result in manual error.




In addition, the switches often times work in conjunction with another electrical device, such as a lamp as part of an electrical assembly. Often, the lamp is positioned vertically above or below the switch and has two terminals protruding therefrom. Like the switch, the lamp requires external conductors to remain in electric contact with the lamp terminals. Some circuits require the lamp to be connected to the circuit via an electrical circuit element and an external conductor. The conductors and/or circuit element leads are typically soldered onto the lamp terminals and then terminated. Similar to the switch, the conductors and/or circuit element leads must be connected to the appropriate lamp terminals for proper functionality of the lamp in the electrical circuit. This process is also very tedious and can result in manual error during installation.




In the past, external conductors and/or circuit element leads were manually soldered onto the appropriate switch and electrical device terminals, increasing manual error and labor manufacturing costs.




Accordingly, there continues to be a need for an insulated electrical connector that eases the process of connecting a switch to a circuit within an apparatus. Preferably, such a connector eliminates most, if not all of the circuit element soldering otherwise required for these devices. Further, such a connector also avoids the need for multiple, individual connectors for each switch or lamp terminal.




SUMMARY OF THE INVENTION




The present invention relates generally to insulated connectors. A first embodiment of a connector of the invention is configured for use with an associated switch. The switch includes three protruding co-planar switch terminals parallel and spaced from one another. The connector comprises first, second, and third contacts. Each contact includes a terminal receiving portion configured to cooperate with one of the associated three switch terminals and an external conductor receiving portion configured to cooperate with an external conductor.




The first embodiment of the connector also includes an insulating housing having at least three cavities parallel to one another and defining a cavity plane. Each cavity includes a terminal receiving portion and a first conductor opening formed therein.




Each contact is positioned within the housing so that the terminal receiving portions of each contact and cavity are substantially aligned. The conductor receiving portion and the conductor openings of the contacts and cavities are substantially aligned and configured to receive an external conductor transverse to the cavity plane.




A second embodiment of the invention is an insulated connector for use with an associated electrical assembly that has upper and lower terminals vertically spaced from one another. The insulated connector comprises at least one upper contact, at least one lower terminal contact, and at least one lower circuit element contact. The second embodiment also includes an insulated housing that has at least one upper cavity, at least one lower terminal cavity, and at least one lower circuit element cavity. The second embodiment also includes at least one circuit element that has first and second leads.




The upper contacts, lower terminal contacts, and lower circuit element contacts are positioned within the upper cavities, lower terminal cavities, and lower circuit element cavities of the housing so that the connector is configured to receive upper and lower terminals of the associated electrical assembly, and external conductors. The first and second leads of the circuit element are interposed within the contacts so that the upper contacts and lower circuit element contacts are in electrical contact with one another.




Other features and advantages of the present invention will be apparent from the following detailed description, the accompanying drawings, and the appended claims.

DETAILED DESCRIPTION OF THE INVENTION




While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a specific embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated.




It should be further understood that the title of this section of this specifically, normally, “Detailed Description of the Invention,” relates to a requirement of the United States Patent and Trademark Office, and does not imply, nor should be referred to limit the subject matter disclosed and claimed herein.




The present insulated connectors


10


,


200


are configured for use with switches


12


and electrical assemblies


14


. Connectors


10


,


200


incorporating aspects of the invention provide for a compact connector and reliable electrical contact between a switch


12


or electrical assembly


14


, which may include circuit elements


16


, and external conductors


18


.




Connectors


10


,


200


of the invention include a housing


20


,


208


with cavities


22


,


210


,


212


,


214


formed therein, and contacts


24


,


202


,


204


,


206


positioned within the cavities


22


,


210


,


212


,


214


.





FIG. 1

depicts a first embodiment


10


of a connector incorporating aspects of the invention in connection with a three position switch


12


having three terminals


26


(FIGS.


2


and


5


). The connector


10


includes at least one contact, and is shown in

FIGS. 2 and 5

incorporating three contacts


24


. The connector also includes a housing


20


(

FIGS. 3 and 5

) having at least three cavities


22


formed therein. The connector preferably includes five cavities formed therein, as shown in

FIGS. 1-3

, and


5


. It should be noted that connectors


10


,


200


can also function with other switches


12


that incorporate a different number of terminals and that also have a different number of positions. A different number of terminals would require a different number of connector cavities and contacts, and a different number of switch positions would dictate the number of external conductors to be connected to the connector.





FIG. 2

shows contacts


24


having a terminal receiving portion


28


configured to cooperate with the terminals


26


of the switch


12


, and an external conductor receiving portion


30


configured to cooperate with an external conductor


18


. Preferably, the contacts


24


are formed having first (top)


32


and second (bottom)


34


surfaces parallel to one another, and a third (lateral)


36


surface substantially orthogonal to and extending between the first and second surfaces


32


,


34


. In a preferred embodiment, a loaded beam


38


, which can include a dimple


40


(

FIGS. 2 and 4

) formed thereon, can be formed on the contact third surface


36


. A portion


42


of the second surface


34


can also be cut away.




The terminal receiving portions


28


of the contacts


24


cooperate with the switch terminals


26


by receiving the terminals


26


within the space defined by first, second, and third surfaces


32


,


34


,


36


of the contacts


24


. Specifically, when the connector


10


is connected to the switch


12


, the loaded beam


38


abuts against a lateral side


44


of the terminal


26


, and the dimple


40


of the loaded beam


38


cooperates with an aperture


46


formed within the terminal


26


. Further, a bottom end


48


of the terminal


26


is guided and locked into place by the cut away portion


42


of the second surface


34


. Each terminal


26


thus “clicks” into the connector


10


and is in constant electrical contact with its respective contact


24


.




The housing


20


should have at least three cavities


22


formed therein, and is shown in

FIG. 3

with five cavities


22


formed therein. The cavities


22


can be parallel to one another and define a cavity plane CP (FIG.


3


). A terminal receiving portion


50


of each cavity


22


is configured to cooperate with the switch terminals


26


(FIG.


5


). The contacts


24


are positioned within the cavities


22


so that the terminal receiving portions


28


,


50


of the contacts


24


and cavities


22


are substantially aligned. Thus, the terminal receiving portion


50


of each cavity


22


also receives a corresponding switch terminal


26


when the switch


12


is connected to the connector


10


. The cavities


22


of the housing


20


insulate the contacts


24


from one another so that the contacts


24


are not in electrical contact with one another.




The embodiment of

FIG. 2

shows the external conductor receiving portions


30


of the contacts


24


including first and second insulation displacement connector grooves


52


,


54


. The insulation displacement connector grooves


52


,


54


are formed within the first and second surfaces


32


,


34


of the contacts


24


. As shown in

FIG. 2

, the external conductor receiving portions


30


of the contacts


24


cooperate with the external conductors


18


by receiving the conductors


18


within the first and second insulation displacement connector grooves


52


,


54


. It should be noted that in other embodiments, not shown, the external conductor receiving portion


30


can include only one insulation displacement connector groove formed on the first or second surface


32


,


34


.





FIGS. 3 and 5

shows first and second conductor openings


56


,


58


formed within the cavities


22


of the housing


20


. The first and second conductor openings


56


,


58


are substantially aligned with the first and second grooves


52


,


54


of the contacts


24


. As shown in

FIGS. 1 and 5

, this allows for the external conductors


18


to be received in the conductor openings


56


,


58


and insulation displacement connector grooves


52


,


54


transverse, and preferably substantially orthogonal, to the cavity plane CP.




Preferably, as shown in

FIGS. 2-3

, the external conductor receiving portions


30


of the contacts


24


and external conductor openings


56


,


58


of the housing are formed at respective distal ends


64


,


66


of the contacts


24


and cavities


22


, and the terminal receiving portions


28


,


50


of the contacts


24


and cavities


22


are formed at their respective proximal ends


60


,


62


. This configuration advantageously allows the connector


10


to be connected to the switch


12


at a proximal end


68


of the connector


10


(FIGS.


1


and


5


), and the external conductor


18


to be inserted within the conductor receiving portions


30


and conductor openings


56


,


58


of the contacts


24


and cavities


22


at a distal end


70


of the connector


10


. Thus, the configuration provides spacing between the terminal


26


and conductor


18


, which in turn, if desired, allows for easier termination of a free end


72


of the external conductor


18


. It should be noted, however, that the conductor receiving portions


30


and the conductor openings


56


,


58


need not be at the proximal end


60


,


62


of the contacts


24


and cavities


22


, and the terminal receiving portions


28


,


50


need not be at the distal end


64


,


66


of the contacts


24


and cavities


22


.




Electrical circuits may require a circuit element


16


connected across switch terminals


26


. In such a configuration, connectors


10


for such circuits incorporate contacts


24


that include circuit element lead receiving portions


74


, as shown in

FIGS. 2 and 4

. It should be noted that, although

FIGS. 2 and 4

show the circuit element lead receiving portion


74


in proximity to the terminal receiving portion


28


, this need not be the case. The connectors


10


for circuits requiring circuit elements


16


also incorporate a housing


20


that includes circuit element lead apertures


76


formed therein, as shown in FIG.


3


. Preferably, each cavity


22


includes one circuit element lead aperture


76


formed therein, although this need not be the case.

FIG. 3

shows that the housing


20


can have a circuit element receiving recess


78


. The contacts


24


are positioned in the housing


20


so that the circuit element lead. receiving portions


28


and circuit element lead apertures


76


are substantially aligned. The circuit element


16


can then be placed within the circuit element receiving recess


78


of the housing


20


so that the circuit element leads


80


are interposed within two of the circuit element lead apertures


76


, as shown in FIG.


1


.




An enlarged view of an embodiment of the circuit element lead receiving portion


74


is shown in FIG.


4


. In this embodiment, a first set of insulation displacement connector beams


82


are formed on a second set of insulation displacement connector beams


84


, which are formed on the first surface


32


of the contact


24


. The first set of insulation displacement connector beams


82


form a wide groove


86


and the second set of the insulation displacement connector beams


84


form a narrow groove


88


.




The configuration and design of the two sets of insulation displacement connector beams


82


,


84


shown in

FIG. 4

provide for reliable and constant electrical contact between the circuit element


16


and the contact


24


, and also provide for compact contacts


24


and connectors


10


. Specifically, the first set of insulation displacement connector beams


82


grasps one of the circuit element leads


80


with an interference fit, which allows for permanent circuit element lead


80


deformation. The second set of insulation displacement connector beams


84


provide most of the deflection while still requiring only a minimum gap between the second set of the insulation displacement connector beams


84


. The minimum gap decreases the minimal width MW of the first (top) surface


32


of the contact


24


, and thus reduces overall contact


24


and connector


10


width. The reduction in connector width is beneficial because of the spacing constraints within some of the devices in which connectors


10


are incorporated.




In addition, the design of the two sets of insulation displacement connector beams


82


,


84


allows the contacts


24


to “lock” the leads


80


of the circuit element


16


within the beams


82


,


84


when the contacts


24


are inserted into the housing


20


. As a result, the circuit element


16


is in electrical contact with two of the contacts


24


. Preferably, the connector


10


, with the circuit element


16


connected thereto, is connected to the switch


12


so that, as described above, the switch terminals


26


are in electrical contact with the contacts


24


, and thus the circuit element


16


. In turn, the external conductors


18


can be inserted into the connector


10


so that, as described above, they are received within the conductor receiving portion


30


and conductor openings


56


,


58


, and in electrical contact with the contacts


24


. Note that the two sets of insulation displacement connector beams


82


,


84


are illustrated and described while incorporated on a lower terminal contact


204


of a second embodiment


200


of the invention. The IDC beams


82


,


84


would typically be incorporated in circuit element receiving portions


74


,


236


,


248


of contacts


24


in the first embodiment


10


, and of upper contacts


202


and lower circuit element contacts


206


in the second embodiment


200


.




As shown in

FIGS. 1

,


2


and


5


, the connector


10


can also include an end member


90


for cooperation with the distal end


70


of the connector


10


. The end member


90


preferably includes at least three upper and at least three lower apertures


92


,


94


formed on the top and bottom surfaces


96


,


98


of the end member


90


. The end member of

FIGS. 1

,


2


and


6


includes five upper and lower apertures


92


,


94


formed on the top and bottom surfaces


96


,


98


of the end member. In addition, the end member


90


can have a male connector


100


and the housing


20


can have a female connector


102


to allow the end member


90


to cooperate with the housing


20


. As shown in

FIGS. 1

,


3


and


5


, the end member male connector


100


can be formed as a ledge


104


depending from the top surface


96


of the end member


90


, and the housing female connector


102


can be a ledge


106


formed on a top surface


108


of the housing


20


. As shown in

FIG. 1

, the housing


20


and the end member


90


cooperate with one another so that the first and second conductor openings


56


,


58


of each cavity are substantially aligned with the five upper and three lower apertures


92


,


94


of the end member


90


. If desired, after the end member


90


is connected to the connector


10


, free ends


72


(

FIG. 4

) of the external conductors


18


that extend from the end member


90


lower apertures


94


can then be terminated.





FIG. 7

depicts an exploded view of a second embodiment


200


of a connector incorporating different types of contacts


202


,


204


,


206


and a housing


208


with cavities


210


,


212


,


214


formed therein.

FIG. 7

shows the second embodiment


200


in cooperation with an electrical assembly


14


. The electrical assembly


14


includes a five position switch


216


having three (lower) terminals


218


integral with an electrical device (lamp)


220


having two (upper) terminals


222


. It should be noted that connectors of the invention can also function with other electrical assemblies


14


that incorporate a different number of terminals, and switches having a different number of positions.





FIG. 8

shows a detailed view of a preferred contact design and contact configuration of the second embodiment. Three different types of contacts


202


,


204


,


206


are shown: upper contacts


202


; lower terminal contacts


204


; and lower circuit element contacts


206


. The upper contacts


202


are configured to cooperate with the upper (lamp) terminals


222


of the electrical assembly


14


and with a circuit element


224


. The lower terminal contacts


204


are configured to cooperate with the lower (switch) terminals


218


of the electrical assembly


14


and the external conductors


226


. The lower circuit element contacts


206


are configured to cooperate with the circuit elements


224


and the external conductors


226


. Preferably, the lower terminal contacts


204


and lower circuit element contacts


206


define a lower cavity plane indicated at LCP, as shown in FIG.


9


.




Each contact


202


,


204


,


206


has a design similar to contacts


24


of the first embodiment


10


described above. If desired, the contacts


202


,


204


,


206


can be identical to one another and incorporate the design of contacts


24


of the first embodiment


10


.




As shown in

FIG. 8

, each contact


202


,


204


,


206


preferably includes first (top) and second (bottom) surfaces


228


,


230


parallel to one another, and a third (lateral) surface


232


transverse, and preferably substantially orthogonal, to the first and second surfaces


228


,


230


.




The second embodiment includes at least one upper contact


202


, at least one lower terminal contact


204


, and at least one lower circuit element contacts


206


. A first variation of the second embodiment (not shown) includes two upper contacts


202


, two lower terminal contacts


204


, and two lower circuit element contacts


206


. In the first variation, at least one of the two upper terminals


222


of the electrical assembly


14


is in electrical contact with an external conductor


226


, and at least one of three lower terminals


218


of the electrical assembly


14


is in electrical contact with an external conductor


226


. Specifically, at least one of the two upper contacts


202


is in electrical contact with at least one of the two lower circuit element contacts


206


by way of a circuit element


224


. The at least one of the two lower circuit element contacts


206


is in electrical contact with an external conductor


226


. At least one of the two lower terminal contacts


204


is in electrical contact with an external conductor


226


.




A preferred contact configuration of the second embodiment


200


incorporating the three different types of contacts


202


,


204


,


206


is shown in FIG.


8


: (1) two upper contacts


202


include terminal receiving portions


234


and circuit element lead receiving portions


236


adjacent to one another and are located substantially at a proximal end


238


of the upper contact; (2) three lower terminal contacts


204


include terminal receiving portions


240


and external conductor receiving portions


242


spaced from one another substantially at proximal


244


and distal ends


246


of the lower terminal contacts


204


; and (3) two lower circuit element contacts


206


include circuit element receiving portions


248


and external conductor receiving portions


250


spaced from one another substantially at proximal


252


and distal ends


254


of the lower circuit element contact


206


.




In a preferred configuration, the terminal receiving portions


234


,


240


, external conductor receiving portions


242


,


250


, and circuit element lead receiving portions


236


,


248


have a similar design and cooperate with the upper and lower terminals


222


,


218


, external conductors


226


, and leads


256


of the circuit elements


224


, respectively, as do the terminal receiving portions


28


, conductor receiving portions


30


, and circuit element lead receiving portions


74


of the first embodiment


10


. It should be noted, however, that the contacts


202


,


204


,


206


and the respective terminal receiving portions


234


,


240


, external conductor receiving portions


242


,


250


, and circuit element lead receiving portions


236


,


248


can be designed and configured differently, which different designs are within the scope and spirit of the present invention. Further, like the contact design of the first embodiment


10


, the external conductor receiving portions


242


,


250


need not be spaced from the terminal receiving portions


242


or the circuit element lead receiving portions


248


of the lower terminal contacts


204


and lower circuit element contacts


206


, respectively. Likewise, the circuit element lead portions


236


need not be adjacent the terminal receiving portions


234


of the upper contacts


202


.




Preferably, as shown in

FIG. 8

, the upper contacts


202


and lower circuit element contacts


206


are in electrical contact with one another by way of circuit elements


224


. The circuit elements


224


can be, for example, a diode


258


, a connecting wire


260


or the like. The upper terminal


222


, which cooperates with the terminal receiving portion


234


of the upper contact


202


, can thus be in electrical contact with an external conductor


226


by way of the lower circuit element contact


206


, which includes its respective external conductor receiving portion


250


. Thus, although both the upper and lower terminals
