Description
TECHNICAL FIELD
The present invention generally relates to routing twisted conductor pairs of a cable to a jack module and, in particular, to devices, systems and methods for controlling the consistency with which the twisted conductor pairs are routed.
DESCRIPTION OF THE RELATED ART
As is known, communications patch panels frequently incorporate the use ofjack modules
100
, as shown in
FIG. 1
, that can be readily attached to and removed from the patch panel. Typically, existing jack modules
100
include a housing
102
having a front portion
104
and a back portion
110
. The front portion
104
is visible to the user of the patch panel (not shown) and includes one or more jack openings
106
configured to receive a communication connector (not shown). The front portion
104
and the back portion
110
matingly engage each other and serve to protect a printed wiring board
130
, one or more jack receptacles
136
, and a plurality of insulation displacement connectors
138
. The jack receptacles
136
are mounted to the front side
132
of the printed wiring board
130
while the insulation displacement connectors (IDCs)
138
are mounted to the back side
134
. Traces (not shown) on the printed wiring board
130
electrically connect the IDCs
138
to the electrical contacts
137
(
FIG. 2
) housed within the jack receptacles
136
. As assembled, each jack receptacle
136
aligns with a jack opening
106
in the front portion
104
of the housing while the IDCs
138
are aligned with a terminal connection region
112
disposed on the back portion
110
. As shown, the front portion
104
and the back portion
110
of the housing are held together with assembly tabs
108
on the front portion that engage assembly notches
109
on the back portion
110
.
FIG. 2
shows a front view of the jack module
100
, as would be seen by a user of a typical communications patch panel.
FIGS. 3 and 4
show the terminal connection region
112
in greater detail. As shown in
FIG. 4
, the terminal connection region
112
consists of two substantially parallel rows
114
of wire guide posts
116
and wire guide splitters
117
, altematingly disposed along each row
114
. As best seen in
FIG. 3
, adjacent wire guide posts
116
and wire guide splitters
117
have a terminal slot
118
disposed therebetween. Each terminal slot
118
allows access to one of the IDCs
138
disposed within the parallel rows
114
. Physical and electrical contact is made between a conductor (not shown) and an IDC
138
by urging the conductor into the terminal slot
118
until the conductor passes between the opposed portions of thc IDCs contact tail
139
FIG.
1
). Opposed portions of the contact tail
139
cut through insulation disposed around the conductor, thereby making electrical contact.
Referring now to
FIG. 4
, the manner of electrically connecting a cable including a plurality of twisted pairs to an existing jack module
100
is addressed. First, a technician determines which IDCs
138
are associated with the desired jack receptacle
136
. Here, the IDCs
138
of interest are accessed by way of the pairs of terminal slots labeled
118
a
,
118
b
,
118
c
, and
118
d
, each of the pairs of the terminal slots
118
being configured to receive the conductors from one of the cable's twisted conductor pairs. Once the desired IDCs
138
have been determined, the technician urges the desired conductor into the appropriate IDC, typically using a device such as a punch-down tool (not shown). As shown, one twisted pair would be inserted into each pair of terminal slots
118
A-D. The wire guide splitters
117
assist the technician in separating the conductors of each twisted conductor pair, thereby making it easier for the technician to insert the desired conductor into the desired IDC
138
.
Such methods of routing twisted pairs on the back of existing jack modules
100
have proved adequate for existing performance levels. This is because in the past variation of the routing of twisted pairs, from pair to pair, has had little effect if any on performance. However, recent developments, such as patch panels requiring category 6 performance levels, are much more sensitive to variations in twisted pair dress and routing.
Therefore, there is a need for improved devices, systems and methods that address variations in twisted pair dress and routing and/or other shortcomings of the prior art.

DETAILED DESCRIPTION
Reference will now be made to the drawings wherein like numerals indicate corresponding parts throughout the several views. As shown in
FIG. 5A
, an embodiment of a back-end variation control cap
140
is shown in an inverted position. The back-end variation control cap
140
includes an upper portion
142
and a bottom portion
150
, with a plurality of twisted pair channels
146
connecting the upper portion
142
and the bottom portion
150
. Preferably, each twisted pair channel
146
is configured to receive a twisted conductor pair
124
from a communications cable
120
, as shown in FIG.
7
. This particular embodiment includes four twisted pair channels
146
is for use with a communications cable
120
that includes four twisted conductor pairs
124
housed within a cable jacket
122
.
Referring now to
FIG. 6A
, the bottom portion
150
of the back-end variation control cap
140
includes a plurality of wire constraints
156
disposed along the bottom edges
154
of a pair of opposed end walls
152
. Preferably, each wire constraint
156
is configured to frictionally engage an individual conductor
126
from a twisted conductor pair
124
(FIG.
5
C). In the embodiment shown, this is accomplished by providing a pair of opposed surfaces
158
that are separated by a distance that is slightly less than the outer diameter of each conductor
126
. The bottom portion
150
also includes a plurality of twisted pair splitters
160
. Preferably, each twisted pair splitter
160
includes a pointed, or knife-like, ridge
162
that allows a technician to separate the individual conductors
126
within each twisted conductor pair
124
. A twisted pair splitter
160
is disposed on the bottom portion
150
adjacent each of the twisted pair channels
146
. Therefore, in the embodiment shown, there are four twisted pair splitters
160
. A pair of routing posts
164
are centrally located on the bottom portion
150
. The routing posts
164
assist a technician to route the conductors
126
in a desired fashion.
A plurality of punch-down walls
170
also are included. One punch-down wall
170
is provided for each conductor
126
that is to be routed within the back-end variation control cap
140
. Preferably, the punch-down walls
170
are disposed in substantially parallel pairs, each pair including a punch-down wall
170
disposed on opposing sides of each twisted pair splitter
160
and extending to an associated wire constraint
156
. Preferably, as shown in
FIG. 5A
, the punch down walls
170
are substantially parallel to the longitudinal center line of the back-end variation control cap
140
and are disposed such that two pairs of the punch-down walls
170
are on opposed sides of the center line. As shown in
FIG. 5B
, each punch-down wall
170
includes a notch
174
which is configured to prevent excessive force from being applied to the portion of each conductor
126
that is being engaged with its associated IDC
138
(FIG.
1
).
In Operation
As previously noted, the embodiment shown is configured for use with a standard communications cable
120
that includes a cable jacket
122
and four twisted conductor pairs
124
, as shown in FIG.
7
. For ease of description, the four twisted conductor pairs are designated
124
a
,
124
b
,
124
c
and
124
d.
During use, each twisted conductor pair
124
a-d
is routed through the corresponding twisted pair channel
146
a-d
, as shown in FIG.
7
. The twisted conductor pairs
124
a-d
are pulled through the twisted pair channels
146
a-d
until the cable jacket
122
abuts the upper portion
142
of the back-end variation control cap
140
. Next, as shown in
FIG. 6A
, the individual conductors
126
of each twisted conductor pair
124
a-d
are separated using the twisted pair splitters
160
. The twisted pair splitters
160
facilitate separation of the typically small diameter conductors
126
. As well, the twisted pair splitters
160
help ensure that the conductors
126
of each twisted conductor pair
124
a-d
remain uniformly parallel to each other as the conductors
126
extend outwardly toward the wire constraints
156
, thereby helping to insure uniformity in the manner of routing of the twisted conductor pairs
124
a-d.
For ease of description, reference will now be made only to twisted conductor pair
124
a
. After the conductors
126
a
of twisted conductor pair
124
a
have been separated at the twisted pair splitter
160
, each conductor
126
a
is extended outwardly toward a corresponding wire constraint
156
a
. The conductors
126
a
are disposed adjacent the bottom ledge
172
of an associated punch-down wall
170
(FIG.
5
B). After the conductors
126
a
have been routed along the punch-down walls
170
, the conductors
126
a
are frictionally restrained by the wire constraints
156
a
, thereby maintaining the conductors
126
a
in the desired routing positions. As well, by frictionally engaging the conductors
126
a
with the wire constraints
156
a
, the communications cable
120
is held in place such that the cable jacket
122
remains adjacent the upper portion
142
of the back-end variation control cap
140
. By repeating the above steps discussed with regard to twisted conductor pair
124
a
for twisted conductor pairs
124
b-d
, the twisted conductor pair routing arrangement as shown in
FIG. 6A
is achieved.
FIG. 6D
is a view of the back-end variation control cap
140
taken along line
6
D-D of FIG.
6
A. Note, conductors
126
a
are retained within wire constraints
156
a
and conductors
126
b
are retained within wire constraints
156
b.
After the twisted conductor pairs
124
a-d
have been routed as desired, the back-end variation control cap
140
is positioned above the back portion
110
of the jack module, see, for example, jack module
100
(FIG.
4
), such that the twisted conductor pairs
124
a-d
are aligned with the appropriate terminal slots
118
. For the routing configuration shown in
FIG. 6A
, when the back-end variation control cap
140
is properly aligned with the back portion
110
, the twisted conductor pairs
124
a-d
will be aligned with the terminal slots
118
a-d
, respectively. The back-end variation control cap
140
is then urged into position adjacent the back portion
110
by engaging the punch-down tool sockets
144
(
FIG. 7
) with a punch-down tool (not shown). As the back-end variation control cap
140
is urged into position adjacent the back portion
110
, the conductors
126
of the twisted conductor pairs
124
a-d
are urged downwardly through the terminal slots
118
a-d
and into both physical and electrical contact with the contact tails
139
of the IDCs
138
(FIG.
1
).
FIG. 7
shows the back-end variation control cap
140
as assembled to jack module
100
. Preferably, the bottom portion
150
of the back-end variation control cap
140
is configured such that the wire guide posts
116
and wire guide splitters
117
nest therein. Note, physical contact between the conductors
126
and the IDCs
138
maintain the back-end variation control cap
140
in the desired position adjacent the jack module in this embodiment.
As shown in FIG.
6
B and
FIG. 6C
, multiple routing options are possible for the twisted conductor pairs
124
a-d
.
FIG. 6B
discloses an arrangement wherein adjacent twisted conductor pairs
124
b
and
124
d
crossover one another. This arrangement is achieved by routing the twisted conductor pairs
124
a-d
through the associated twisted pair channels
146
a-d
, respectively. Next, twisted conductor pairs
124
a
and
124
c
are routed to their respective pairs of wire constraints
156
a
and
156
c
. To achieve crossover between adjacent twisted conductor pairs
124
b
and
124
d
, twisted conductor pair
124
b
is routed to the twisted pair splitter
160
that is disposed adjacent twisted pair channel
146
d
. Once twisted conductor pair
124
b
has been separated with the twisted pair splitter
160
, the conductors
126
b
are routed to wire constraints
156
d
and are frictionally engaged therein. To complete the adjacent crossover arrangement, twisted conductor pair
124
d
is routed through a gap
166
disposed between the routing posts
164
. The twisted conductor pair
124
d
is separated into individual conductors
126
d
with the twisted pair splitter
160
that is disposed adjacent twisted pair channel
146
b
. The conductors
126
d
are then routed to and secured in the wire constraints
156
b
. Once the twisted conductor pairs
124
a-d
have been arranged and secured within the back-end variation control cap
140
, the cap is ready for installation on the jack module
100
in the manner previously discussed with regard to FIG.
6
A. Once assembled, this routing arrangement results in twisted conductor pairs
124
b
and
124
d
being inserted into terminal slots
118
d
and
118
b
, respectively.
FIG. 6C
discloses an arrangement in which twisted conductor pairs
124
a
and
124
d
which are disposed diagonally to each other within the communications cable
120
are routed in a crossover fashion. To achieve this configuration, twisted conductor pairs
124
b
and
124
c
are separated into pairs of substantially parallel conductors
126
and secured within their respective wire constraints
156
b
and
156
c
. Next, twisted conductor pair
124
a
is routed around the centrally disposed routing posts
164
and are separated into conductors
126
a
with the aid of twisted pair splitter
160
disposed adjacent to twisted pair channel
146
d
. The conductors
126
a
are then extended outwardly in a substantially parallel fashion and arc secured within wire constraints
156
d
. Similarly, twisted conductor pair
124
d
is routed around the centrally located routing posts
164
opposite twisted conductor pair
124
a
. Twisted conductor pair
124
d
is separated into conductors
126
d
with the assistance of twisted pair splitter
160
which is disposed adjacent twisted pair channel
146
a
. The conductors
126
d
are then extended outwardly in a substantially parallel manner and engaged within wire constraints
156
a
. With the twisted conductor pairs
124
a-d
so arranged, the back-end variation control cap
140
is in condition for mounting to the jack module
100
. The routing arrangement shown in
FIG. 6C
results in twisted conductor pairs
124
a
and
124
da
being inserted into terminal slots
118
d
and
118
a
, respectively.
