Abstract
An electrical connector has an insulative housing, a plurality of first contacts extending through the housing for electrically contacting conductors in a mating connector, and a cover releasably secured to the housing and contacting at least one of the plurality of first contacts.
Description
FIELD OF THE INVENTION
The present invention relates to an electrical connector which has a component package and a retaining device that releasably retains the component package within the connector. More particularly, the present invention relates to such a connector where the retaining device at least partially shields the component package.
BACKGROUND OF THE INVENTION
Electrical connectors, including electric components such as modular jacks, can use various types of filters to reduce or eliminate noise, and can use LEDs to indicate a system status. Such filters may include a three terminal capacitor or a common mode choke coil. A disadvantage in the use of such filters is that they may complicate the production of the connector. A need, therefore, has been perceived for providing a filtered electrical connector or an electrical connector with one or more LEDs that are assembled in a relatively simple manner.
The use of an integral ferrite element for this purpose is proposed in Japanese Patent Publication 64-2273. This reference discloses a modular jack having a modular insert installed in a casing. The body of the insert is formed with ferrite, and on one side of the insert body insert holes are formed for introducing connecting lines to be connected to respective contact springs.
While this reference would appear to simplify the apparatus used for noise filtering in modular jacks, such filtered connector is larger than a comparable non-filtered connector. Thus, a need exists for further increasing the compactness of such filtered connector.
U.S. Pat. No. 5,456,619 discloses a filtered modular jack assembly having an outer insulative housing with open front and rear sides. A ferrite element with vertical conductive wires is positioned adjacent the rear end, and an elongated insulative insert is superimposed over the ferrite element. The insulative insert is fixed to the housing, and the conductive wire extends vertically from the ferrite element over the upper side of the insert to its terminal end and then bends downwardly and rearwardly to rest on the top surface of an interior medial wall in the housing. The connector, however, cannot interchange various filters. Accordingly, a need still exists for a connector jack which can achieve such compactness while using multiple types of filtering elements.
A need also exists for such a connector that can securely removably receive any of a plurality of components, such as a filter element, LED, or the like, as mounted within or on a component package, especially in the field. Accordingly, if in the field or elsewhere it is determined that one component is not desired or is not operating properly, the component package there-having may simply be removed from the jack, and be replaced by another component package having a more suitable component. A need further exists for such a connector that is properly shielded.
SUMMARY OF THE INVENTION
The aforementioned need is satisfied by the present invention, in which an electrical connector has an insulative housing, a plurality of first contacts extending through the housing for electrically contacting conductors in a mating connector, and a cover releasably secured to the housing and contacting at least one of the plurality of first contacts.
In one embodiment of the present invention, a modular jack releasably receives a component package having an exterior surface, a plurality of first conductive elements mounted on the exterior surface, and at least one electric device mounted thereon and electrically coupled to the first conductive elements. The jack has an insulative insert mounted within an interior section of an insulating housing. The insert has a forward portion and a rear portion, where the rear portion defines a recess for receiving the component package therein. The recess defines a mouth thereof, and the component package is received within the recess through the mouth thereof. Each first conductive element of the component package resides at a respective predetermined location within the recess when the component package is received within the recess.
A plurality of first contacts are mounted to the forward portion of the insert to electrically contact conductors in a connector inserted toward the forward portion of the insert and into the jack. Each first contact corresponds to a first conductive element in the component package, extends from the forward portion of the insert generally to the predetermined location of the corresponding first conductive element, and terminates at a termination in communication with such predetermined location. The termination of each first contact electrically contacts the corresponding first conductive element at the respective predetermined location when the component package is received within the recess. A retaining device is releasably secured over the mouth of the recess to releasably retain the component package as received in the recess.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to
FIGS. 1-5
, wherein like numerals are used to indicate like elements throughout, one type of modular jack is shown for purposes of disclosing typical features in modular jacks. As will be seen in
FIGS. 6-10
, wherein like numerals are also used to indicate like elements throughout, the modular jack of the present invention shares many common features with the modular jack shown in
FIGS. 1-5
.
As seen in
FIGS. 1 and 2
, the modular jack has an outer insulative housing which is shown generally at numeral
10
. This housing includes a top wall
12
, a bottom wall
14
and a pair of opposed lateral walls
16
and
18
. The housing could be constructed of a thermoplastic polymer having suitable insulative properties and may have conventional metallic exterior shielding
61
. Within these walls is an interior section
20
which has a rear open end
22
and a forward open end
24
. Projecting upwardly from the bottom wall in this interior section there is a medial wall generally shown at numeral
26
which has a rear side
28
and a front side shown generally at numeral
30
which includes a bottom front side
31
, a top front side
32
, a recessed medial front side
34
, and an inclined top side
36
which slopes upwardly and forwardly from its rear side toward its front side. Adjacent to the lateral walls, the medial wall has lateral extensions
38
and
40
which serve as projections to retain other elements as will be hereafter explained. Interposed between these lateral extensions there are a plurality of wire separation extensions as at
42
,
44
and
46
and between these wire separation extensions there are plurality of slots as at
48
.
As will be appreciated and as further explained hereafter, the wall and recesses of the outer insulative housing may interact to receive an insulative insert
72
(best seen in FIGS.
3
and
4
). In the type of insert
72
shown in the drawings, each conductor in the jack is part of/mounted to such insert
72
. Alternatively, the housing
10
could have terminals that correspond to such conductors (not shown) so as to make electrical connection between the conductors in the housing
10
and the insert
72
. Importantly, the housing
10
and the insert
72
may be formed as a substantially unitary body without departing from the spirit and scope of the present invention.
Extending downwardly from the bottom wall there are alignment and retention posts
50
and
52
. The lateral wall
16
includes a lower shoulder
54
, another shoulder
56
, a lower main wall
58
, an upper main wall
60
and a recess interposed between the lower and upper main wall
58
,
60
to receive a tab
62
of shield
61
when a plug (not shown) enters the jack. It will be seen that the lateral wall
18
has substantially identical features as lateral wall
16
. The top wall
12
includes an upper bridge section
64
, a lower bridge section
66
, a front recess
68
and a rear recess
70
.
Referring particularly to
FIGS. 3 and 4
, the insulative insert which may be received by the housing
10
is shown generally at numeral
72
. This insert
72
has a vertical section shown generally at numeral
74
which includes a base wall
76
. The vertical section also includes opposed side walls
82
and
84
. The vertical section also has a front wall
94
in which there are apertures
96
and
98
. Finally the vertical section
74
of the insert
72
defines a recess
100
. The insert also has a horizontal section shown generally at numeral
102
which has a plurality of grooves as at groove
104
and
106
which extend from the rear to the front of this horizontal section. In these grooves there are conductors as at wire
108
(FIG.
2
).
Referring particularly to
FIG. 5
, a cap element which may be mounted to the insert
72
is shown generally at numeral
110
. This cap element
110
has a rear wall
112
and defines a recess
114
therein. The cap also has a top end wall
116
and a bottom end wall
118
which have respectively grooves as at groove
120
and
122
. Conductors as at wire
124
and
126
are positioned in each of these grooves. The cap also has side walls
128
and
130
which have respectively latches
132
and
134
for engaging the side walls
82
and
84
of the insulative insert. A filter means such as common mode chokes 136 and 138 may be mounted on the inner or recess side of the wall 112, as is more filly discussed in U.S. patent application Ser. No. 08/863,654, hereby incorporated by reference. Other filtering elements such as inductive serial filters, differential filters, low pass capacitive filters and other magnetic filters may be substituted for the common mode choke.
It will be appreciated that a compact modular jack as shown in
FIGS. 1-5
facilitates the use of several different types of filtering elements depending on specific needs. That is, a large variety of filters or other components may be housed in the recess of the insert. Consequently, the use of a standard package as is required in many prior art modular jacks is not necessary so as to allow greater flexibility in meeting specific application needs. It will also be appreciated, however, that the filtering element or the like in the jack of
FIGS. 1-5
is not normally removable once inserted. Accordingly, if in the field or elsewhere it is determined that one filter element or the like or other suitable electric device is not desired, such filter element or the like or other electric device cannot simply be removed from the jack and be replaced by another more suitable filter element or the like.
Referring now to
FIGS. 6-10
, it is seen that in contrast to the jack of
FIGS. 1-5
, an electrical connector such as modular jack
200
of the present invention accommodates a component package
202
having a suitable electric device
203
, where the component package
202
is in fact removably insertable and therefore exchangeable in the field or elsewhere with other component packages
202
having other suitable electric devices
203
. Thus, and as described above, if it is determined that one electric device
203
is not desired, the component package
202
there-having may simply be removed from the jack
200
, and be replaced by another component package
202
having a more suitable electric device
203
.
In particular, and referring now to
FIG. 6
, the modular jack
200
of the present invention is similar to the jack shown in
FIGS. 1-5
in that such jack
200
has an insert
72
with walls that define a recess
100
, where the insert
72
is mounted within an interior section of an insulating housing
10
. Notably, the housing
10
and the insert
72
of the jack
200
may be formed as a unitary body without departing from the spirit and scope of the present invention. Here, the recess
100
securely removably receives the component package
202
having an electric device
203
therein.
As should be understood, the electric device
203
may be the aforementioned filter, LED, or the like or any other electric device that may be received in/secured to the component package
202
such that at least a portion of the component package
202
may be received in the recess
100
. For example, the electrical device
203
may be a resistor or capacitor, a simple electronic circuit, an antenna, a complex integrated circuit, etc.
As seen in
FIG. 6
, the component package
202
has a substrate with a first surface
204
, a plurality of first conductive elements
206
mounted on the surface
204
, and at least one electric device
203
mounted thereon and electrically coupled to the first conductive elements
206
. In one embodiment of the present invention, and as seen in
FIG. 8
, the component package
202
could use a circuit substrate such as a generally planar circuit board with magnetics mounted thereto, where the circuit board includes the first conductive elements
206
and the magnetics are appropriately coupled thereto. In another embodiment of the present invention (not shown), the component package
202
could be an integral module with circuitry encapsulated therein. Of course, other types of component packages
202
may be employed without departing from the spirit and scope of the present invention.
In terms of the present invention, the insert
72
as shown in
FIGS. 1-5
may be defined to include a forward portion
208
(i.e., the horizontal section
102
, generally) and a rear portion
210
(i.e., the vertical section
74
, generally), where the rear portion
210
defines the recess
100
that receives at least a portion of the component package
202
therein. As seen, the recess
100
defines a mouth
220
thereof, where the component package
202
is received within the recess
100
through such mouth
220
. Generally, the mouth
220
is adjacent the exterior of the jack
200
, although such mouth
220
need not necessarily be immediately adjacent such jack
200
exterior. For example, the mouth
220
may be retracted somewhat into the recess
100
. Again, the insert
72
is mounted within an interior section of the insulating housing
10
.
As should be understood from
FIG. 6
, each first conductive element
206
of the component package
202
resides at a respective predetermined location within the recess
100
when the component package
202
is received within the recess
100
. Each predetermined location may preferably be generally at the mouth
220
of the recess
100
, as shown, although each predetermined location may be elsewhere without departing from the spirit and scope of the present invention. Moreover, each predetermined location may be at different places relative to mouth
220
of the recess
100
without departing from the spirit and scope of the present invention. For example, the predetermined locations of some of the first conductive elements
206
may be at the mouth
220
of the recess
100
, while the predetermined locations of some of the other first conductive elements
206
may be farther into the recess
100
.
As seen in
FIG. 6
, a plurality of first contacts
212
are mounted to the forward portion
208
of the insert
72
. As should be understood, such first contacts
212
are for electrically contacting conductors (not shown) in a connector
213
inserted toward the forward portion
208
of the insert and into the jack
200
. Each first contact
212
corresponds to a first conductive element
206
in the component package
202
, in that a corresponding first contact
212
and first conductive element
206
are intended to be in electrical contact with one another. As seen, then, each first contact
212
extends from the forward portion
208
of the insert
72
generally to the predetermined location of the corresponding first conductive element
206
and terminates at a termination
214
that proximate such predetermined location.
As should now be evident, the termination
214
of each first contact
212
electrically contacts the corresponding first conductive element
206
on the exterior surface
204
of the component package
202
as received in the recess
100
, where such first conductive element
206
is at such predetermined location merely on the basis of the component package
202
being properly positioned in the recess
100
. In one embodiment of the present invention, one or more appropriate keying mechanisms, such as complementary slots and keys, pins and holes, etc. (not shown) may be employed to ensure such proper positioning. Such keying mechanisms may not in all cases be necessary.
In one embodiment of the present invention, and as seen in
FIG. 6
, each termination
214
of the plurality of first contacts
212
is a spring termination. That is, each termination
214
is constructed from a suitable material such that the termination
214
can act as a spring if biased in a particular manner. This helps accommodate tolerance differences between component packages
202
being inserted into the housing
10
. Here, the spring terminations
214
may be biased toward the mouth
220
of the recess
100
, whereby the terminations
214
of the plurality of first contacts
212
in combination act to urge the inserted component package
202
out of the recess
100
. Accordingly, and as seen in
FIGS. 6-10
, the jack
200
preferably includes a retaining device
215
that is releasably secured over the mouth
220
of the recess
100
to act against the bias of the spring terminations
214
and thereby releasably retain the component package
202
as received in the recess
100
. Retaining device
215
may be stamped and formed from the same conductive materials as the shield
217
, such as a copper alloy. Other materials, including insulative materials, may be employed without departing from the spirit and scope of the present invention.
In one embodiment of the present invention, the jack
200
includes features for releasably securing the retaining device
215
to the remainder of the jack
200
against the bias of the spring terminations
214
. Such features may include one or more of the aforementioned appropriate keying mechanisms. As best seen in
FIG. 9
, the features may include a pair of opposing latches
216
on the retaining device
215
for cooperating with a corresponding pair of opposing latch catches
218
on the housing
10
when the retaining device
215
is properly positioned over the mouth
220
of the recess
100
. Alternatively, the housing
10
could have the latches
216
and the retaining device
215
could have the catches
218
. Of course, other structures may be employed as the retaining device securing device
216
,
218
without departing from the spirit and scope of the present invention.
In one particular embodiment, and as seen, the main body of the jack
200
(i.e., the combination of the housing
10
and the insert
72
) has opposing lateral sides, where each lateral side has one of the latch
216
and the latch catch
218
. Correspondingly, the retaining device
215
includes a main panel
215
a for being positioned over the mouth
220
of the recess
100
, and a pair of opposing arms
215
b that each extend generally transversely from the main panel
215
a
and toward the main body of the jack
200
, where each arm
215
b
has the other of the latch
216
and the latch catch
218
. As should now be evident, the retaining device
215
is suitably sized so that when mounted to the main body of the jack
200
, the arms
215
b
of such retaining device are adjacently positioned to receive and ‘hug’ the main body of the jack
200
therebetween, such as with an interference fit. Thus, the respective latches
216
and latch catches
218
combine and interlock to secure the retaining device
215
to the main body of the jack
200
. In so doing, the component package
202
is secured to the jack such that the termination
214
of each first contact
212
electrically contacts the corresponding first conductive element
206
on the exterior surface
204
of the component package
202
.
Retaining device
215
also includes tabs
215
c
that extend from the main panel
215
a
. Tabs
215
c
limit the insertion of component package
202
into recess
100
and provide additional points of contact between retaining device
215
and the external shield
217
. The retaining device
215
may be separate and apart from the remainder of the jack
200
(as shown), may be unitary with shield
217
, or may be coupled in some fashion to the remainder of the jack
200
(not shown) by a coupling device such as a hinge, for example. If coupled in some fashion by a coupling device, the coupling device preferably can withstand multiple cycles of coupling and un-coupling, and does not suffer any degradation such as for example fatigue.
In one embodiment of the present invention, the retaining device
215
also provides shielding. That is, the retaining device
215
is constructed from a suitable conductive/shielding material such as a copper alloy, whereby the shielding retaining device
215
at least partially shields the component package
202
from externally originating electromagnetic interference, and also shields the exterior of the jack
200
from electromagnetic interference that originates from the component package
202
. Preferably, the shielding retaining device
215
along with an external shield
217
around housing
10
combine to provide adequate electromagnetic interference shielding.
In such embodiment, the jack
200
may further comprise such external jack shield
217
which is fitted over the insert
72
and housing
10
and which defines an opening corresponding to the mouth
220
of the recess
100
, whereby the opening allows external access to the recess
100
through such mouth
220
. Like the shielding retaining device
215
, the jack shield
217
is constructed from a suitable conductive/shielding material such as a copper alloy. Thus, in combination, the jack shield
217
and the shielding retaining device
215
, substantially shield the component package
202
from externally originating electromagnetic interference, and also shield the exterior of the jack
200
from electromagnetic interference that originates from the component package
202
. Preferably, the shielding retaining device
215
electrically contacts the jack shield
217
when releasably secured to the jack
200
over the mouth
220
of the recess
100
. Accordingly, if the jack shield
217
is electrically grounded by way of an underlying substrate
222
(FIG.
6
), then so too is the shielding retaining device
215
electrically grounded. In this embodiment, each catch
218
may include an opening, a protuberance, or a depression in the side wall of the jack shield
217
.
In one embodiment of the present invention, the retaining device
215
includes a component package securing structure
219
for securing the component package
202
to such retaining device
215
. The component package securing structure
219
may releasably secure the component package
202
, for example by way of a pair of securing clips (FIGS.
7
-
9
), or may fixedly secure the component package
202
, for example by way of a piece of adhesive tape (not shown) or in any other suitable manner. The component package securing device
215
may include one or more of the aforementioned appropriate keying mechanisms. Although physically connected, component package
202
could be electrically isolated from retaining device
215
.
Accordingly, the retaining device
215
can carry the component package
202
, and replacement of a component package
202
in a jack
200
is as simple as removing or ‘popping out’ one retaining device
215
, with one component package
202
secured thereto by the component package securing structure
219
thereof, and inserting or ‘popping in’ another retaining device
215
, with another component package
202
secured thereto by the component package securing structure
219
thereof. Alternatively, if the component package securing device releasably secures the component package
202
, the retaining device
215
is removed, the component package
202
is removed from the component package securing structure
219
, and another component package
202
is inserted into such component package securing structure
219
. The retaining device
215
with the new component package
202
may then be popped back in to jack
200
.
As is to be expected, the jack
200
is to be mounted to an underlying substrate
222
(shown in
FIG. 6
) such that signals pass through the jack
200
between the first contacts
212
and second contacts
224
that couple to the substrate
222
. In one embodiment of the present invention, and as shown in
FIG. 6
, the jack
200
has a plurality of the second contacts
224
mounted to the rear portion
210
of the insert
72
for electrically contacting the underlying substrate
222
. Preferably, and as seen, each second contact
224
extends from the rear portion
210
of the insert
72
to the recess
100
and terminates at a termination
228
in communication with the recess
100
. Likewise, it is seen that in the present invention, the component package
202
has a plurality of second conductive elements
226
mounted on the exterior surface
204
of such package
202
, where the electric device
203
on the component package
202
is electrically coupled to the second conductive elements
226
. Accordingly, the termination
228
of each second contact
224
securely electrically contacts a corresponding second conductive element
226
on the exterior surface
204
of the component package
202
as received in the recess
100
.
Similar to the first contacts
212
and first conductive elements
206
, and as should be understood from
FIG. 6
, in one embodiment of the present invention, each second conductive element
206
of the component package
202
resides at a respective predetermined location within the recess
100
when the component package
202
is received within the recess
100
. Each predetermined location may preferably be generally at the mouth
220
of the recess
100
, as shown, although each predetermined location may be elsewhere without departing from the spirit and scope of the present invention. Moreover, each predetermined location may be at different places relative to mouth
220
of the recess
100
without departing from the spirit and scope of the present invention. For example, the predetermined locations of some of the second conductive elements
226
may be at the mouth
220
of the recess
100
, while the predetermined locations of some of the other second conductive elements
226
may be farther into the recess
100
.
Each second contact
224
corresponds to a second conductive element
226
in the component package
202
, in that a corresponding second contact
224
and second conductive element
226
are intended to be in electrical contact with one another. As seen, then, each second contact
224
extends from the rear portion
210
of the insert
72
generally to the predetermined location of the corresponding second conductive element
226
and terminates at a termination
228
that is adjacent such predetermined location. As with the first contacts
212
and first conductive elements
206
, the termination
228
of each second contact
224
electrically contact the corresponding second conductive element
226
on the exterior surface
204
of the component package
202
as received in the recess
100
, where such second conductive element
226
is at such predetermined location merely on the basis of the component package
202
being properly positioned in the recess
100
.
Similar to the terminations
214
, in one embodiment of the present invention, and as seen in
FIG. 6
, each termination
228
of the plurality of second contacts
212
is a spring termination. That is, each termination
228
is constructed from a suitable material such that the termination
228
can act as a spring if biased in a particular manner. Like the spring terminations
214
, the spring terminations
228
may be biased toward the mouth
220
of the recess
100
, whereby the terminations
214
and
228
of the plurality of first and second contacts
212
,
224
in combination act to urge the inserted component package
202
out of the recess
100
. Accordingly, the retaining device
215
that is releasably secured over the mouth
220
of the recess
100
acts against the bias of the spring terminations
214
and
228
. Such bias provides suitable contact force with the package
202
.
In one embodiment of the present invention, and as seen in
FIG. 6
, the first and second conductive elements
206
,
226
are located on generally opposing sides of the component package
202
. However, the elements
206
,
226
may also be located elsewhere without departing from the spirit and scope of the present invention.
In one embodiment of the present invention, and as best seen in
FIG. 6
, the first and/or second conductive elements
206
,
226
mounted on the exterior surface
204
of the component package
202
comprise conductive pads that are generally coextensive with such exterior surface
204
. Here, ‘coextensive’ means flush with respect to such exterior surface
204
, or at least minimally differing in elevation with respect to such exterior surface
204
. In another embodiment of the present invention (not shown), the first and/or second conductive elements
206
,
226
mounted on the exterior surface
204
of the package
202
comprise conductive extending elements that extend away from such exterior surface
204
. For example, the extending elements may include spring terminations or spring loops.
In one embodiment of the present invention, and as seen in
FIG. 10
, the component package
202
includes or is associated with one or more LEDs
230
or the like, each of which lights upon the occurrence of a pre-defined event. The LEDs
230
may reside on/in the component package
202
, or may be positioned on the shielding retaining device
215
physically apart from the component package
202
but coupled thereto using suitable wiring or a flex circuit, for example. Illustratively, and as may be appreciated, one LED
230
may light when outgoing data is being transmitted, another LED
230
may light when incoming data is being received, and another LED
230
may light to show that the jack
200
is active and has a connector
213
coupled thereto. Preferably, the light from each LED
230
is communicated to the front face of the housing
10
adjacent the mouth
220
thereof. Accordingly, such light may be observed if the bulk of the jack
200
is positioned interior to a structure (such as a cabinet or the like). For example, the housing
10
may include an appropriate aperture through which such light may be seen at such front face, or may include a light pipe
232
or the like embedded therein which guides such light to such front face. Alternatively, such light pipe
232
may reside on a top or side face of the housing, as is shown.
In the present invention, a jack
200
can securely removably receive any of a plurality of electric devices as mounted within or on a component package
202
, and such package
202
may be easily replaced, especially in the field, by removing a retaining device
215
that holds the component package
202
in proper position in the jack
200
. While the present invention has been described in connection with the embodiments as shown in
FIGS. 6-10
, it is to be understood that other similar embodiments may be used or modifications and additions may be made to the described embodiments for performing the same function of the present invention without deviating therefrom. Therefore, the present invention should not be limited to any single embodiment, but rather construed in breadth and scope in accordance with the recitation of the appended claims.
