Abstract
An insulated electrical connector is used with an associated switch. The switch includes three protruding co-planar switch terminals parallel and spaced from one another. 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
222
,
218

242
,

of the lower terminal contacts
204
and lower circuit element contacts
206
in the lower cavity plane LCP. Such a configuration reduces labor costs by allowing only one machine to connect the external conductors
226
to the connector in one plane, as opposed to requiring a more elaborate machine or two machines to connect external conductors to the upper and lower terminals in two different planes.
