Description
PAT(~.~ cQ~7n CONN~CTOR
Techn; c;~l F; el ~1 The present invention relates to an electrical connector and more particularly to a patch cord connector for a cro~-connect system that achieves category 5 required performance and i8 more readily termina~ea~le.
RAC~Y.O.---.1 Of th~ Inv~nt;on Cros~-connect wiring systems are well-known and include panels or wiring blocks which terminate cables and have an end adapted to interconnect with patch cord connectors. The~e cross-connect systems are generally utilized for connecting between wiring blocks of incoming and outgoing wiring systems, such as can be found in wiring closets. The 110 system patch cord connector 15 generally terminates a cable holding a plurality o~ wires and connects to a 110-style connector on a wiring block or panel. With the recent increase in the number of users on networks, a~ well as the higher data rates being utilized, it has become a necessity to design electrical connectors 20 for use with the cross-connect system which will reduce the ef~ect of the crosstalk to achieve category 5 performance. One example can be seen in the prior art patch cord connector of U.S. Patent No. 5,226,835 to Baker, III et al. and assigned to AT&T Bell Laboratories.
25 AT&T~s patent utilizes a crossing over of adjacent contacts to help reduce crosstalk between adjacent pairs.
The bending required~to achieve the proper crossover results in a more difficult manufacturing pxocess of the conductor~ and a more complicated assembly operation.
30 Additionally, the particular placement and extent o~ the CA 02238~26 1998-0~-2~
WO9~13899 PCT~S97/17324 bending of the conductors results in a higher su~ceptibility to buckling during connecting and disconnecting of the patch cord connector.
Therefore, improvement in the art of designing patch 5 cord co~ne~tors for cross-connect sy~tems is ~till desired.
~ry of the Tnvent;~n It is therefore, an object of the present invention to provide an improved cross-connect syqtem patch cord connector.
It is further an object of the present invention to provide an improved patch cord connector achieving category 5 performance.
It is still further an object of the present lS invention to provide a patch cord connector which i~ more readily both factory and field terminateable.
In general an electric connector of the present invention includes a dielectric housing and a plurality of conductors situated within the housing having a generally 20 flat blade portion di~posed at an output end of the housing, an intermediate portion and an insulation displacement contact (IDC) portion for receiving an individual wire, wherein the intermediate portions of adjacent conductor~ are alternately situated ~ub~tantially 2S in a lower or an upper plane and are alternately of a shorter or a longer length.

n~r;pt;~n of the pre~ ~mhor~im~nt A patch cord connector embodying the concept of the present invention is designated generally by the reference numeral lO in the accompanying drawings. As shown in 25 FIGS. 1 and 3, patch cord connector lO is comprised of a pair of matable housing sections including a bottom conductor hou~ing section 12 and a top wire housing ~ection 14 formed for example, by a flame retardant polycarbonate resin. The patch cord connector lO
30 terminates a cable 70 at an input end 30 of the housing WO 98/1389g rCT/US97/17324 and includes conductors 16 with end portions positioned at an output end 32 of the housing that interconnect with insulation diRplacement contacts on a wiring block patch panel (not ~hown).
As best ~een in FIG. 3, conductor housing section 14 includeQ a plurality of conductors 16 including a generally ~lat blade portion 18 disposed at the output end 32 of the housing, an intermediate portion 20 and an insulation displacement contact portion 22 for receiving a o plurality of individual wires of cable 70. The conductors 16 are factory inserted and firmly embedded in their respective conductor slots 24. The conductor IDC 22 is supported against the forces from mating with a connecting ~lock IDC (not shown) by front 26 and rear 3upportR 28 15 formed on the conductor housing section. The intermediate portion 20 includes a small jog 34 near the IDC end 22 which i~ necessary in order to fit all of the conductors 16 within the spacial restraints of the conductor housing 14. The conductor's blade portion 18 includes a coined 20 area 36 formed into a 45~ bevel which allows for easier in~ertion of the patch cord conductors 16 into the connector block IDC's (not shown).
A~ seen in FIGS. 3 and 4, the conductors 16 alternate between a longer intermediate portion and a shorter intermediate portion and also between the intermediate portion substantially e~tending in a lower plane and an upper plane. The longer conductors extend rearwardly in the lower plane from a bottom side of the flat blade contact while the shorter conductors extend rearwardly in 30 the upper plane from a top side of the blade portions 18.
The intermediate portions o~ the longer conductors include s a conical impression 54 which helps hold the conductor tightly in the slot 24. The shorter conductors are additionally fixed in the conductor slots 24 by retaining nubs 56 formed in the top front region of the slots of the plug 10 As best seen in FIG. 7, t~e patch cord connector 10 is either factory or field terminated by first stripping the cable 70 end of its jacket and snapping the cable 70 into the securement ribs 38 and retaining clips 40 ~ormed lQ on the wire housing section 14. The individual wires 42 are then ~ed into their respective wire slots 44 which temporarily secure the wires 42. As can be-seen in ~IG.
8, the excess wire is then trimmed flush against the angled front 46 of the wire housing 12. This angled face 15 46 assures that if the wires 42 are trimmed slightly proud of the face 46, they do not interfere with the conductor housing 14 upon assembly. Once the wires 42 are trimmed, the conductor housing 14 is snapped together with the wire housing 12. This action causes the IDC portions 22 to 20 pierce the wire insulation establishing continuity. The strain relief feature 48 p;nche~ the cable, eliminating stress on wires 42 during connection and di~connection.
The patch cord connector 10 of the present invention utilizes a unique conductor configuration specifically 2~ designed to use the parallel runs and relative distances between conductor pairs to reduce the effect of cross-talk. Generally, cross talk is increased when conductors run parallel to each other in close proximity.
Additionally, the larger the surface area of the adjacent 30 conductor portions, the greater the cross-talk which is heard by nearby conductor portions.
CA 02238~26 1998-0~-2~
WO98/13899 PCT~S97/17324 A st~n~rd patch cord connector contains a plurality of conductors compri~ing a plurality of pairs of adiacent con~1lctors. Generally, one pair of conductors i5 u~ed as a transmitting pair and a second pair of conductors is a s recei~ing pair. Each o~ the conductors within the transmitting pair emits noise, while each conductors of the receiving pair hears the noise from each of the transmitting c~n~l~ctors. The cross-talk between pairs can be ~; n i ~; zed by increasing the distance between the conductors, or by balancing the amount of noi~e heard by each of the receiving conductors from the transmitting conductors. When you have a balanced pair, the receiving conductors hear the same amount of noise from each of the transmitting conductors. This reduces the cross-talk 15 between the pairs since the noise i8 cancelled out with the ~ame amount being heard by both receiving conductors.
As can best be seen with reference to FIGS. 5 and 6 which shows two pairs o~ conductors without the housing, the proposed conductor configuration has been specifically 20 designed to reduce the effect of the cross-talk by balancing the cross-talk between the transmitting and the receiving pair. The transmitting pair of conductors is indicated by conductors T-l and T-2 and the receiving pair of conductors are shown as conductors ~-3 and R-4 in the 25 drawings. As can be seen in FIG. 6, the intermediate portions 20 of adjacent conductors run substantially in two different planes with the shorter conductors extending rearwa~dly from a top end of the flat blade portion 18 so as to be primarily disposed in an upper plane and the 30 longer conductors extending rearwardly from a bottom end of the flat blade portion 18 80 as to be primarily CA 02238~26 1998-0~-2~
WO98/13899 PCT~S97/17324 di~posed in a lower plane in order to reduce the overall noise between ;~;ately adjacent pairs. This separation of adjacent conductors reduces the noise heard by adjacent conductor~.
s Therefore ~ m~k; n~ the alternating conductors longer results in a reduced cross-talk effect by balancing the noise heard by conductors R-3 and R-4 from conductor T-2.
That i8, the ~lat blade portion 18 of R-3 and the small intermediate portion near the IDC end of conductor ~-3 i~
in closer proximity to the adjacent portions of conductor T-2 than the similar portiona of R-4. Therefore without modifying receiving conductor R-4 the noise heard by R-3 from T-2 would be subQtantially higher than that of R-4 from T-2. However, the extra length of a parallel run between conductors T-2 and R-4 increases the noise between T-2 and ~-4 to approximate the noise which is heard by conductor R-3 from conductor T-2. Therefore, by having the intermediate portions of adjacent transmitting and receiving conductors in spaced apart planes the total cross-talk effect of the immediately adjacent conductors T-2 and R-3 is minimized. Cro~stalk is increased between T-2 and R-4 by having the intermediate portions 20 of the T-2 and R-4 run together for a longer parallel run to achieve h~l ~nce .
2s The length of the shorter conductors in the preferred embo~;~e~t as indicated by "B" in FIG. 5 i8 .447 inches.
Therefore, in order to properly balance the crosstalk, it ha~ been learned through testing that the longer conductors should be .30 inches longer as indicated by "C"
30 to have a length indicated by "A" of .747 inches.
CA 02238~26 1998-0~-2~
WO98113899 PCT~S97117324 This conductor arrangement to achieve cross-talk reduction by balancing the noise heard by the receiving con~l1ctors is effective regardless of which pair in the patch cord i~ the transmitting pair and which i8 the s recei~ing pair.
Also, as can be seen in FIG. 3, located in the rear of the patch cord connector is a ~train relief feature 48 and the cavities 60 which accepts the snaps 40 of the wire housing section 14. Front snaps 62 located between the conductors secure the front of the patch cord assembly together. It i8 important to note the ~naps 62 are located on the conductor housing 12 and not on the wire housing 14 as in previous patch cord connectors. This po~itioning allows ~or rapid wire installation in the wire 15 housing without any interference with the snaps. The rear snaps 64 including their guide posts 66 secure the rear of the plug assembly together by engaging with corresponding opening 68 on the conductor housing 12.
While the particular preferred embodiment of the 20 present invention has been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the teachings of the invention. The matter set forth in the foregoing de~cription and accomr~nying drawing~ i9 offered 25 by way of illustration only and not as a limitation. The actual scope of the in~ention is intended to be defined in the ~ollowing claim~ when viewed in their proper perspective based on the prior art.
