Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to electrical connectors and, more particularly, to an electrical connector having a plurality of finger contacts defining a ground plane.
BACKGROUND OF THE INVENTION
Electrical connectors are used to place electrical devices, such as printed circuit boards, in electrical communication with one another. Typically, an electrical connector includes a set of electrical contacts that are adapted to receive a first set of members from the first device to be coupled. The set of contacts extends from the electrical connector and terminates in a second set of members that couple to the second device to be coupled, placing the two devices in electrical communication with each other through the electrical connector.
In order to minimize high frequency noise, it is desirable to provide a ground plane near the electrical contacts in the electrical connector, the ground plane being connected to ground potential. Typically, one or more of the electrical contacts will be coupled to the ground plane. Known electrical connectors are typically provided with certain predetermined electrical contacts connected to the ground plane. Accordingly, unique electrical connectors must normally be provided for each pair of devices to be interconnected.
There is therefore a need for an electrical connector design that allows for customization regarding which pins are grounded and which are not. The present invention is directed towards meeting this need.
SUMMARY OF THE INVENTION
The present invention relates to electrical connector having at least one ground plate adapted to be electrically connected to a ground potential, wherein the ground plate includes a plurality of substantially parallel elongated, bendable fingers. Each finger is spaced from every other finger in the ground plate and may be independently bent inwardly. In one embodiment, the electrical connector also includes a plurality of electrically conducting members or contacts, preferably formed on the edge or surface of a printed circuit board or card. The electrically conducting members are positioned adjacent to the ground plate(s), such that when a ground plate finger is bent inwardly, it can make selective and independent electrical contact with a preselected electrically conducting member. Preferably, the electrical connector includes a pair of ground plates oriented substantially in parallel, such that the fingers of each ground plate may be bent inwardly towards the opposite ground plate to define plurality of electrically interconnected electrically conducting members held firmly by the fingers of the two ground plates.
One object of the present invention is to provide an improved electrical connector device. Related objects and advantages of the present invention will be apparent from the following description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
FIGS. 1-4A
illustrate a first embodiment of the present invention, an edge-type electrical connector
20
for receiving a plurality of electrical contacts and independently configurable to provide any desired pattern of grounding thereto. Referring to
FIGS. 1-3
, the electrical connector includes a housing portion
22
having a generally open top slot for receiving electrical contacts (generally conductive pads on the edge of a printed circuit board). The housing
22
further contains a plurality of electrical contact receptors or sockets
24
for receiving the individual electrical contacts and holding them in electric communication with a plurality of respective conductors
28
. The plurality of electrical contact receptors
24
is generally arranged in a single row, although the plurality of electrical contact receptors
24
could be arranged in two or more parallel rows. As illustrated in
FIG. 1
, each electrical contact receptor
24
comprises a pair of elongated electrically conducting members
26
positioned opposite each other and having a separation distance therebetween of slightly less that the width of a received contact, such that a contact inserted therebetween would be held in electrical communication with the electrical contact receptor
24
by the spring forces generated by the elastically deflected electrically conducting members
26
. While electrical contact receptors
24
comprising multiple pairs of elongated electrically conducting members
26
are preferred, any convenient electrical contact receptor configuration may be selected, such as sockets or the like. The electrical contact receptors
24
terminate in electrical conductors
28
extending from the housing
22
. The conductors
28
may be bent away from the housing, if desired (see
FIG. 1
) or left straight (see FIG.
2
).
The housing
22
further includes one or more ground plates
30
positioned therein and oriented substantially parallel to the row of electrical contact receptors
24
.
FIG. 2
illustrates the connector
20
with the housing
22
removed. The ground plates
30
are formed of an electrically conductive material, such as copper, steel, an alloy, or the like. The ground plates
30
are preferably substantially planar and are more preferably positioned substantially parallel to the row of electrical contact receptors
24
. The ground plates
30
include a plurality of individual elongated finger portions
32
formed therein. The finger portions
32
preferably extend parallel to the electrically conducting members
26
and are positioned such that each electrically conducting member
26
is spaced opposite a finger portion
32
. In other words, each electrically conducting member
26
and at least one respective finger portion
32
are positioned substantially adjacently, such that the finger portion
32
may be bent sufficiently inwardly toward the electrical conducting member
26
to make electrical contact therewith.
Referring to
FIGS. 4A and 4B
, the ground plates
30
are discussed in greater detail. Each finger portion
32
is preferably defined by a (preferably rectangular) window
34
. Each finger portion
32
extends from the ground plate
30
on one side of the window
34
and extends into the window
34
therefrom. The finger portion
32
is preferably an elongated rectangular member extending within the window portion
34
and is more preferably centered therein. The window portions
34
need not be discrete. In other words, the finger portions
32
may be spaced such that there is a gap between each finger portion
32
that is not filled by solid ground plate material. Additionally, the finger portions
32
may be formed with substantially no window portions
34
. Referring to the ground plate
30
illustrated in
FIG. 4B
, the ground plate
30
further includes mounting portions
35
for securely attaching the ground plate
30
to the rest of the electrical connector
20
.
The electrical connector
20
is preferably produced with all of the finger portions
32
oriented flush with their respective ground plate
30
. In other words, the finger portions
32
are preferably unbent when the electrical connector
20
is produced, although the electric connector
20
may be produced with one or more of the finger portions
32
bent. The electrical connector
20
may therefore be readily modified to have any desired connector ground pin configuration by simply bending the appropriate fingers
32
inwardly to ground the desired electrical contact receptor
24
positions (the bending may be done manually by the end user, mechanically, or during the stamping or forming process). The electrical connector
20
may thusly be customized at any time after production, increasing its utility and flexibility of use. Customization may be done in bulk following manufacture to address a technical requirement. Alternately, the electrical connectors
20
may be sold as manufactured and customized in the field to meet the specific needs of an individual user.
FIGS. 5-11
illustrate a second embodiment of the present invention, a board-to-board type electrical connector
120
including a male connector assembly
121
and a female connector assembly
122
adapted to receive the male connector assembly
121
in electric communication. Both housing portions
121
,
122
are adapted to receive electrical signals from an attached device. The female connector assembly
122
further includes a pair of independently configurable ground plates
30
adapted to provide any desired pattern of grounding thereto. The electrical connector includes a female connector assembly
122
having a generally open central slot
123
for receiving the compatible male connector assembly
121
in electrical communication. The central slot
123
further includes a plurality of electrical contact receptors
124
positioned therein. The male connector assembly
121
includes a plurality of sequentially disposed electric contacts
125
. These electric contacts
125
are typically disposed as two rows, one on either elongated side of the male connector assembly
121
. Further, each male electric contact
125
preferably has two elongated prongs
125
A and
125
B extending therefrom, as is illustrated in FIG.
8
.
As noted above, the female connector assembly
122
includes a plurality of electrical contact receptors or sockets
124
for receiving the first elongated prongs
125
B of the male electrical contacts
125
in electric communication. The plurality of electrical contact receptors
124
is generally arranged one or more rows to match the rows of electric contacts
125
on the male connector assembly
121
. However, the male electric contacts
125
and the female electric contact receptors
124
could be disposed according to any convenient geometry.
As illustrated in
FIG. 9
, each electrical contact receptor
124
comprises an elongated electrically conducting member
126
having a rounded contact tip
127
extending therefrom. The elongated electrically conducting member is adapted to extend into the female connector assembly
122
with the rounded contact tip protruding into the slot
123
. A first elongated prong
125
B of a male electric contact
125
positioned on a male connector assembly
121
inserted into the female connector assembly
122
would be held in electrical communication with the electrical contact receptor
124
, as shown in FIG.
6
. The electrical contact receptor
124
also includes a second elongated portion
128
adapted to extend from the female connector assembly
122
for electrical connection to a device, such as a printed circuit board.
As shown in
FIG. 7
, the male connector assembly preferably has a T-shaped cross-section with a top bar portion
130
and an elongated portion
131
adapted to extend into the central slot
123
when the male connector assembly
121
is joined with the female connector assembly
122
. As shown in
FIG. 10
, the electrical contacts
125
are inserted into the male connector assembly
121
such that the first elongated prong
125
B extends through the elongated portion
131
and at least partially protrudes therefrom. The second elongated prong
125
A extends through the top bar portion
130
.
As illustrated in
FIG. 11
, the female connector assembly
122
further includes one or more ground plates
30
positioned adjacent one or more grounding slots
134
formed therein. As discussed above and shown in
FIGS. 4A and 4B
, the ground plates
30
are made of an electrically conducting material, such as copper or steel. The ground plates
30
include a plurality of individual elongated finger portions
32
formed therein. Each ground plate
30
is oriented such that the fingers
32
are substantially adjacent and spaced from the second elongated prongs
125
B when the male and female connector assemblies
121
,
122
are mated. The finger portions
32
preferably extend parallel to the first elongated prongs
125
A and are positioned such that each first elongated prong
125
A of a male electrical contact
125
on a male connector assembly
121
inserted into the female connector assembly
122
is spaced opposite a finger portion
32
. In other words, each male first elongated prong
125
A and at least one respective finger portion
32
are positioned substantially adjacently, such that the finger portion
32
may be bent sufficiently inwardly toward the male second first prong
125
A to make electrical contact therewith. Since the ground plate
30
is electrically grounded, contact by a male first elongated prong
125
A with a finger portion
32
will electrically ground the associated male second elongated prong
125
B, any electrical receptor
124
in contact with the associated male second elongated prong
125
B, as well as any device electrically connected thereto.
As with the electrical connector
20
embodiment discussed above, the electrical connector
120
is preferably produced with all of the finger portions
32
oriented flush with their respective ground plate
30
, i.e., unbent, although the electric connector
120
may be produced with one or more of the finger portions
32
bent. The electrical connector
120
may therefore be readily modified to have any desired connector ground pin configuration by simply bending the appropriate fingers
32
inwardly to ground the desired male electrical contact
121
positions (the bending may be done manually by the end user, mechanically, or during the stamping or forming process). The electrical connector
120
may thusly be customized at any time during or after production, increasing its utility and flexibility of use. Customization may be done in bulk following manufacture to address a technical requirement. Alternately, the electrical connectors
120
may be sold as manufactured and customized in the field to meet the specific needs of an individual user.
In operation, predetermined fingers
32
are urged into electrical contact with pre-selected electrically conducting members
26
(or male electrical contacts
125
), thereby electrically connecting pre-selected contact receptors
24
/contacts
125
to a common ground plate
30
. Which contact receptors
24
/contacts
125
are grounded to the ground plate
30
is predetermined according to the configuration of the device or devices to be mated to the electrical connector
20
/
120
. In other words, the end user determines which contact receptors
24
/contacts
125
are to be connected to the ground plate
30
based on the wiring of the device connected to the electrical connector
20
/
120
. Electrical contacts (not shown) extending from the device(s) are electrically connected to the electrical connector
20
; those contacts received by electrical connector such that they are ultimately in electric communication with the fingers
32
urged are thusly grounded by the ground plate
30
.
Preferably, two ground plates
30
are provided and oriented in parallel, such that each respective finger
32
of each ground plate
30
is paired with an opposite respective finger
32
of the other ground plate
30
. The fingers
32
are spaced a finite, non-zero distance apart sufficient to accommodate the placement of a conductor partially filling the space in between the fingers
32
. In other words, there is sufficient room between the unbent fingers
32
for the insertion of at least one electrically conducting member therebetween such that the neither finger
32
electrically contacts the electrically conducting member. The fingers
32
may be plastically deformed (i.e., bent) towards one another such that at least one finger
32
electrically connects with an electrically conducting member, such as an electrical contact receptor
124
or an electric contact
125
, positioned therebetween and desired to be grounded. However, other designs are contemplated having only a single ground plate
30
or multiple asymmetrically disposed ground plates
30
.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are to be desired to be protected.
