Description




FIELD OF INVENTION




The present invention relates generally to the field of modular plugs for terminating cables. More particularly, it relates to an improved plug for terminating communication cables having a plurality of twisted signal pairs of conductors and controlling the positions of the untwisted conductors in order to reduce near-end crosstalk.




BACKGROUND OF THE INVENTION




Communications networks generally transmit data at a high frequency over cables having a plurality of twisted signal pairs of conductors. For example, according to currently accepted performance standards, Category


5


products operate at frequencies up to 100 MHz and Category


6


products operate at frequencies up to 250 MHz over Unshielded Twisted Pair (UTP) cable that contains eight (8) individual conductors arranged as four (4) twist pairs. When data is transmitted via an alternating current in a typical telecommunication application at such high frequencies, each individual conductor and each signal pair creates an electromagnetic field that can interfere with signals on adjacent conductors and adjacent signal pairs. This undesirable coupling of electromagnetic energy between adjacent conductor pairs, referred to as crosstalk, causes many communications problems in networks.




Crosstalk is effectively controlled within communication cables through the use of twisted pairs of conductors. Twisting a signal pair of conductors causes the electromagnetic fields around the wires to cancel out, leaving virtually no external field to transmit signals to nearby cable pairs. In contrast, Near End Crosstalk (NEXT), the crosstalk that occurs when connectors are attached to twisted pair cables, is much more difficult to control. Since twisted signal pairs must be untwisted into individual conductors in order to attach a connector, high levels of NEXT are introduced when portions of transmitted signals within the connector are electromagnetically coupled back into received signals.




In efforts to control NEXT, a wide variety of modular plugs have been developed for terminating communications cables that contain twisted signal pairs of conductors. As communication technology advances, however, and allows transmission at higher and higher frequencies, the modular plugs known in the prior art are no longer capable of maintaining NEXT levels within the ranges specified in widely accepted national performance standards. For Category


6


products, for example, the Commercial Building Telecommunications Wiring Standard (ANSI/TIA/EIA-568) specifies a de-embedded NEXT test plug range which all patch cord plugs should meet to ensure interoperable Cat


6


performance. In order to satisfy TIA/EIA 568B-2.1, patch cord plugs must be designed with low NEXT variability centered within the specified de-embedded NEXT test plug range. In standard plug designs, however, pair-to-pair distortion, twist rate, and individual conductor positions are not strictly controlled. Hence, large variations of NEXT performance occur. Prior art modular plug designs also cause increased de-embedded NEXT variability by utilizing strain relief components that consist of a latching bar that pinches the cable jacket, prohibiting cable movement within the plug housing. In order to generate sufficient retention force, these bar style strain relief components significantly deform the cable jacket and the twisted pair conductors within the jacket. This pinching deformation causes distortion and displacement of twisted pairs of conductors that in turn causes increased de-embedded NEXT variability.




Accordingly, there is a demand for an improved modular cable termination plug.




SUMMARY OF THE INVENTION




The present invention overcomes the deficiencies of the prior art by providing an improved modular cable termination plug. The improved modular cable termination plug of the claimed invention utilizes mechanical features that will control the twist rate, un-twisted length, and position of individual conductors as well as twisted pairs of conductors within a cable and ensure repeatable placement of the conductors from the undisturbed cable to the point of termination. Accordingly, in comparison to the modular cable termination plugs available in the prior art, the claimed invention is more versatile and provides reduced NEXT variability and enhanced performance.




In accordance with the present invention, the improved modular cable termination plug comprises a conductor divider having an entrant barb and a plurality of conductor divider channels, a load bar having a plurality of through holes, and a plurality of contact terminals of alternating heights. In one embodiment of the invention, the conductor divider and the load bar hold conductors in three separate horizontal planes in order to minimize crosstalk between adjacent signal pairs of conductors. One embodiment of the present invention also provides for a housing and a plurality of slots in the load bar that are adapted to receive the plurality of contact terminals. The integral slots in the load bar provide an advantage over the prior art by reducing the overall length of untwisted cable within a housing.




It is another feature of the invention to provide a cable strain relief. In one embodiment, a strain relief collar secures the load bar, conductor divider, and cable within a housing. In another embodiment of the claimed invention, a strain relief boot protects the bend radius of the cable.




It is yet another feature of the invention to provide a method of separating and arranging signal pairs of conductors in order to minimize the crosstalk within a modular connector plug. According to the method, untwisted signal pairs are separated and arranged into three separate planes, and individual conductors are separated and arranged in three separate planes and are terminated by contact terminals having varying heights.




These and other features and advantages of the present invention will be apparent to those skilled in the art upon review of the following detailed description of the drawings and preferred embodiments.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




Referring now to the drawings,

FIG. 1

shows an exploded perspective view of a modular plug assembly


100


in accordance with the claimed invention. In the preferred embodiment of the claimed invention, the plug assembly includes a strain relief boot


90


, a strain relief collar


82


, a conductor divider


20


, a load bar


40


, and a housing


60


. The preferred modular plug


100


is depicted in an assembled state in the cross sectional view shown in FIG.


1


A. As shown in

FIG. 1A

, the conductor divider


20


and the load bar


40


are designed to fit within the internal cavity


68


of the plug housing


60


. The conductor divider


20


and the load bar


40


are secured in their proper location within the plug housing


60


by the walls


83


of the strain relief collar


82


. In an assembled state, movement of the conductor divider


20


, the load bar


40


, and the strain relief collar


82


is preferably minimized through the use of an integrated snap. A horizontal latch tab


87


on the strain relief collar


82


engages against the edge of a pocket


72


in the lower surface


70


of the plug housing


60


. In a similar manner, each wall


83


of the strain relief collar


82


has a vertical latch tab


86


that engages against the edges of pockets


94


in the strain relief boot


90


in order to complete the preferred assembly.




The conductor divider


20


of the claimed modular plug assembly is shown in detail in

FIGS. 2-5

. The conductor divider


20


is comprised of an entrant barb


28


and a plurality of divider channels


30


,


31


,


32


,


33


. The entrant barb


28


is designed to be fully inserted into a communications cable


10


and thereby greatly minimize the traditional transition region that is present in prior art plugs between a non-distorted cable and any cable organizing device. It is well known to those skilled in the art that crosstalk can be reduced by limiting the length of manipulated untwisted cable. Accordingly, by substantially reducing the transition region between the cable


10


and the conductor divider


20


, the present invention effectively eliminates a potential source of crosstalk within the modular connector


100


that is present in prior art designs. The entrant barb


28


is preferably in the form of a double post, as shown in

FIG. 2B

, since the double post design can be used in connection with cables


10


that have an internal spline or with splineless cables. When used with a cable


10


having an internal spline, each post in the double post design fits into a corner of the cable spline flush to the end of the cable


10


. This retention eases termination by allowing an installer to free his grasp of the conductor divider


20


while untwisting signal pairs of conductors and seating the signal pairs


12


in the divider channels


30


,


31


,


32


,


33


. While the entrant barb


28


having a double post is preferred, one skilled in the art should recognize that a single post entrant barb


28


as shown in

FIG. 2A

, or any number of other designs could be effectively used according to the claimed invention.




The conductor divider


20


shown in

FIGS. 2-5

also has a plurality of divider channels


30


,


31


,


32


,


33


for separating and arranging the signal pairs


12


of conductors in a communications cable


10


. Since the preferred embodiment of the claimed invention is a Category


6


modular plug that terminates an Unshielded Twisted Pair (UTP) cable that contains eight (8) individual conductors arranged as four (4) twist pairs, the preferred conductor divider


20


has four divider channels


30


,


31


,


32


,


33


. As shown in

FIGS. 4 and 5

, each divider channel


30


,


31


,


32


,


33


is preferably designed to grip and hold one untwisted conductor pair. In the preferred embodiment of the claimed plug assembly


100


, the upper divider channel


30


features a tapered split channel divider


34


, and the side divider channels


32


,


33


have tapered side walls


35


,


36


and retention bumps


37


, all of which help secure conductor signal pairs in an untwisted state within the channels.




The load bar


40


of the claimed modular plug


100


is shown in detail in

FIGS. 6-10

. The load bar


40


preferably has a plurality of through holes


42


that are used to separate and arrange each individual conductor


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


of the cable


10


. In the preferred embodiment, the through holes


42


holds each individual conductor in one of three planes in order to control NEXT. The load bar


40


also has integral slots


44


aligned with each through hole


42


that are adapted to receive a contact terminal


50


.




The modular plug


100


of the claimed invention can be easily assembled in the field. Referring to FIG.


1


and

FIG. 11

, a cable


10


is inserted through the cable clearance hole


92


of the strain relief boot


90


and through the strain relief collar


82


. The twisted pairs of conductors are untwisted, and each untwisted signal pair


12


is placed into one of the plurality of divider channels


30


,


31


,


32


,


33


on the conductor divider


20


.




Since the conductor divider


20


does not have a designated top or bottom surface, the conductor divider


20


can be utilized for both ends of a cable


10


by flipping the conductor divider


20


over to match the orientation of the cable. Accordingly, termination of cables


10


in the field is easier than with prior art designs since the conductor divider


20


can be installed depending on the cable lay and signal pair


12


disturbance can be minimized. In the preferred embodiment shown in the figures, the signal pair


12


of conductors


3


and


6


are placed in the upper divider channel


30


, the signal pair


12


of conductors


4


and


5


are placed in the lower divider channel


31


, and the signal pairs


12


of conductors


1


and


2


and


7


and


8


are placed in side divider channels


32


,


33


. The retention bumps


37


on the side divider channels


32


,


33


help speed the process of termination by holding the signal pairs


12


in place and allowing the installer to focus on seating the next signal pair


12


.




When the signal pairs


12


are placed in a divider channel, the entrant barb


28


of the conductor divider


20


is fully inserted into the cable


10


as shown in

FIG. 11

, thereby eliminating any transition region between the cable


10


and the divider channels


30


,


31


,


32


,


33


. The alignment of the signal pairs


12


within the channel dividers


30


,


31


,


32


,


33


on the installed conductor divider


20


is shown in

FIGS. 4 and 5

. As shown in

FIG. 4

, as the signal pairs


12


emerge from the cable


10


, the signal pair


12


for conductors


3


and


6


and for conductors


4


and


5


are held in a parallel, horizontal arrangement. This arrangement of signal pairs


12


is maintained throughout the divider channels


30


,


31


, except that in the preferred embodiment shown in

FIG. 5

, the signal pair


12


in the upper divider channel


30


is separated by a tapered divider


34


. Referring back to

FIG. 4

, it can be seen that the signal pairs


12


for conductors


1


and


2


and for conductors


7


and


8


will initially be held in a vertical arrangement in the side divider channels


32


,


33


. Within the side divider channels


32


,


33


, the tapered side walls


35


,


36


will gently reposition and secure the signal pairs


12


in a fixed horizontal arrangement at the front surface


27


of the conductor divider


20


, as shown in FIG.


5


.




For the purposes of reducing crosstalk within a connector, securing untwisted signal pairs


12


in a fixed position with the claimed invention offers a distinct advantage over prior art designs that do not control the precise positions of untwisted signal pairs


12


or individual conductors. By eliminating the transition area between the cable and the conductor divider channels and by separating and controlling the conductor signal pairs


12


while the conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


transition from the circular state within the cable


10


to the planar state within the modular plug


100


, NEXT is reduced in the claimed modular plug. NEXT can be even further reduced by arranging the conductor signal pairs


12


in different planes on the front surface


27


of the conductor divider


20


. Preferably, the conductors are arranged horizontally in three separate planes as shown in

FIG. 5

, as a tri-level conductor divider


20


minimizes NEXT between signal pairs


12


of conductors


3


,


6


and conductors


4


,


5


, between signal pairs


12


of conductors


3


,


6


and conductors


1


,


2


, and between signal pairs


12


of conductors


3


,


6


and conductors


7


,


8


. One skilled in the art will also recognize that the positioning and geometry of the divider channels


30


,


31


,


32


,


33


can be modified to tune NEXT variability between signal pairs


12


within accepted levels. For example, the side divider channels


32


,


33


can be raised or lowered, the separation between the upper channel divider


30


and the lower channel divider


31


can be increased or decreased, or the tapered divider


34


in the upper channel divider


30


could be wider or narrower.




Referring now to

FIGS. 12

,


13


and


14


, the load bar


40


is installed following the conductor divider


20


. As shown in

FIG. 12

, each signal pair


12


held by the conductor divider


20


is separated into individual conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


, and each conductor is inserted through a through hole


42


in the load bar


40


. In order to comply with nationally recognized standards, the conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


are arranged in sequential order as shown in

FIGS. 8

,


10


A and


10


B. The load bar


40


also preferably holds the conductors in a staggered alignment and in three horizontal planes as shown in

FIGS. 6-10

. In the preferred embodiment, the staggered placement of conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


in the load bar


40


reduces NEXT by balancing electromagnetic energy transmitted between signal pairs


12


. For example, by placing the through hole


42


for conductor


2


vertically below the through holes


42


for conductor


1


and conductor


3


, conductor


3


will induce a more even magnitude of electromagnetic energy on conductor


1


relative to the horizontally adjacent conductor


2


. Further, one skilled in the art should recognize that by varying the placement of the individual conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


within the load bar


40


, NEXT variability between signal pairs


12


can be tuned within accepted levels. By comparing the embodiment of the load bar


40


in

FIGS. 6

,


7


,


8


, and


10


A to the embodiment of the load bar


40


in

FIGS. 9 and 10B

, an example of how the placement of individual conductors can be varied within the load bar


40


can be seen. Specifically, the distance between conductors


3


and


6


and conductors


4


and


5


can be adjusted in order to tune the NEXT performance of the modular plug


100


.




In order to minimize NEXT, the load bar


40


is preferably installed adjacent to the conductor divider


20


as shown in

FIG. 13

in order to minimize the length of the untwisted conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


. The overall length of the claimed modular plug is also minimized through the use of slots


44


that are integral to the load bar


40


. The integral slots


44


allow the claimed invention to utilize a more compact design than those known in the prior art and thereby enhance the overall performance of the plug. Once the load bar


40


is positioned, the excess cable shown in

FIG. 13

can be trimmed at the cut off face


46


of the load bar


40


, resulting in the complete subassembly shown in FIG.


14


.




In order to complete the assembly of the modular plug


100


, the subassembly shown in

FIG. 14

can be inserted into the cavity


68


of the housing


60


as shown in

FIGS. 1A and 15

. The load bar


40


, conductor divider


20


and cable


10


are preferably secured within the cavity


68


of the housing


60


with the strain relief collar


82


. The walls


83


of the strain relief collar


82


, which has been previously installed on the cable


10


, slide into the cavity


68


of the housing


60


until the latch tab


87


engages against the edge of the pocket


72


in the lower surface


70


of the housing


60


. The engaged strain relief collar


82


exerts a force against the conductor divider


20


within the cavity


68


of the housing


60


, thereby ensuring the proper positioning of the conductor divider


20


and the load bar


40


within the housing


60


and preventing the conductor divider


20


and the load bar


40


from traveling back and out of the housing


60


.




In embodiments where a shielded cable is used, a shielded plug housing


160


is required in order to make an electrical ground connection between the cable


10


and the mating housing


160


. As shown in

FIG. 16

, the shielded plug housing


160


has an electromagnetic interference shield


163


, a pair of contact tabs


165


, and a pair of support tabs


168


. In order to complete assembly of a shielded modular plug, the ground braid of a cable should be folded back onto the cable jacket. Then, when the subassembly shown in

FIG. 14

is inserted into the cavity


68


of the shielded housing


160


, the ground braid of the cable will contact the upper surface


164


of the shield


163


and the pair of contact tabs


165


, forming an electrical ground connection path through the cable and the shield


163


.




In addition to securing the conductor divider


20


and load bar


40


, the strain relief collar


82


also uses a combination of normal and shear forces to secure the cable


10


. In the preferred embodiment of the claimed invention, when the stain relief collar


82


is installed over a cable


10


, the walls


83


of the strain relief collar


82


deflect outwardly. This outward deflection of the walls


83


of the strain relief collar


82


creates an interference fit between the exterior surface of the walls


83


of the strain relief collar


82


and the interior walls


75


of the cavity


68


of the housing


60


. Preferably, as the walls


83


of the strain relief collar


82


are installed into the cavity


68


of the housing


60


, the interference fit causes the walls


83


to deflect inward, resulting in a press fit that generates a normal force on the cable


10


along the entire length of the wall


83


and a shear force at the interior edge of the wall


83


. In some embodiments, these forces may also be enhanced by the placement of cable retention barbs


180


on the inside surface of the walls


83


, as shown in FIG.


17


. With or without the barbs


180


, however, these forces provide superior retention of the cable


10


without the distortion and displacement of twisted pairs of conductors within the cable


10


that occurs with the latching bar strain relief features that are well known in the prior art. Accordingly, the present invention also provides enhanced control over NEXT variability.




After the strain relief collar


82


is engaged in the cavity


68


of the housing


60


, the strain relief boot


90


, also previously installed on the cable


10


, can be secured onto the modular plug assembly


100


. The strain relief boot


90


slides over the walls


83


of the strain relief collar


82


, and the latch tabs


86


are preferably engaged against the edges of the pockets


94


in the strain relief boot


90


. The boot, which is preferably made of a rubberized material, ensures that the minimum bend radius of the cable


10


leaving the modular plug


100


is maintained.




Finally, electrical termination for the modular plug assembly


100


is accomplished by inserting a plurality of contact terminals, preferably insulation piercing contacts (IPCs)


50


, through the slots


62


in the housing


60


which are aligned with the slots


44


in the load bar


40


. As shown in

FIGS. 1

,


9


,


10


A and


10


B, different sizes of contact terminals


50


are used to terminate the connections in the plug assembly


100


. Two or three different sizes of contact terminals may be used, but tall IPCs


54


, Medium IPCs


53


, and short IPCs


52


are preferably alternated and aligned with respective conductors


1


,


2


,


3


,


4


,


5


,


6


,


7


,


8


that are held in a staggered relationship in the load bar


40


. It is known in the art that an alternating IPC pattern minimizes NEXT by balancing coupled electromagnetic energy that is transmitted between contacts, but the unique arrangement of staggered conductors and alternating IPCs disclosed in

FIGS. 6-10

and


15


maximizes this effect. In the preferred embodiment, placing a short contact pin


52


aligned with conductor


2


between two tall contact pins


54


aligned with conductor


1


and conductor


3


compensates conductor


3


to conductor


2


coupling with conductor


3


to conductor


1


coupling. As a result, despite the tall contact


54


for conductor


1


being twice the distance from the contact for conductor


3


as from the contact for conductor


2


, the extra coupling generated by the larger surface area of the tall contact


54


for conductor


1


counterbalances the relatively large amount of coupling induced upon the closer short contact


52


for conductor


2


. In addition, NEXT can be even further minimized in the preferred embodiment by placing a hole


55


in the tall contact terminal


54


corresponding to conductor


3


and thereby reducing the surface area of the contact terminal. The reduced surface area has the effect of reducing the coupling between the contact terminals


50


for conductors


3


and


2


while maintaining the coupling between the contact terminals


50


for conductors


3


and


1


.




It should be understood that the illustrated embodiments are exemplary only and should not be taken as limiting the scope of the present invention. The claims should not be read as limited to the order or elements unless stated to that effect. Therefore, all embodiments that come within the scope and spirit of the following claims and equivalents thereto are claimed as the invention.
