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

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.
