Description

BALANCED INTERCONNECTOR FIELD OF THE INVENTION The present invention relates to a balanced interconnector. In particular, the present invention relates to an interconnector used to interconnect cables comprised of twisted pairs of conductors.

BACKGROUND OF THE INVENTION In data transmission networks, cross-connected coriectors (such as BIX, 110, 210, etc.) are commonly used in telecommunication rooms to interconnect the ends of telecommunications cables, thereby facilitating the maintenance of the network. For example, the prior art discloses crossed connectors comprised of a series of insulated flat straight conductors each comprised of a pair of inverted Displacement Displacement Contact (IDC) connectors connected end-to-end to interconnect a conductor of a first cable with the conductors of a second cable. As is known in the art, all drivers that transmit signals act as antennas and radiate the signal they carry to their general vicinity. Other receiver drivers will receive the irradiated signals as interference. The interference typically adversely affects the signals that are transported by the receiving conductor and with which it must deal if the strength of the received interference exceeds certain predetermined minimum values. The strength of the received interference depends on the capacitive coupling between the transmitting conductor and the receiving conductor which is influenced by a number of mechanical factors, such as the geometry of the conductor and separation between the conductors, as well as the frequency of the signals that are being transported by drivers, protection of drivers, etc. As the frequency of the signal increases, the influence of even small capacitive coupling values can result in significant interference that has damaging effects on signal transmission. Systems designed for the transmission of high frequency signals, such as the oblique four-stranded twisted pair cables that make up the 'ANSI / EIA 568, take advantage of a variety of mechanisms to minimize capacitive coupling between conductors within and between cables. A problem with these systems is that, although the coupling, and therefore the interference, is reduced within the path of the cable, the conductors within the cables must inevitably be terminated, for example in the device or cross connector. Those terminations they introduce irregularities in the system where the coupling, therefore the interference, increases. With the introduction of the Category 6 and Category 6 Augmented standards and the 10G Base T transmission protocol, the permissible levels for all types of internal and external interference, including Near End Transfer (NEXT), Far End (FEXT) and Strange Transfer, have gone down. As a result, the connectors and interconnectors of the prior art are generally no longer able to satisfy the permissible levels of interference. In addition, although long cable elements such as twisted pairs of conductors achieve good interference characteristics through braiding and proper separation of the conductor pairs, when viewed as a whole, the cable is subject to additional interference to each irregularity. These irregularities occur mainly in connectors or interconnectors and typically lead to an aggressive generation of interference between neighboring pairs of conductors which in turn degrades the high frequency bandwidth and limits the data throughput on the conductors. As the transmission frequencies continue to increase, each additional irregularity at the local level, although small, adds to a collective irregularity which may have an impact considerable on the performance of the cable transmission. In particular, the unraveling of the ends of the twisted pairs of conductors to introduce them in the IDC type connections introduces capacitive coupling between the twisted pairs.

DETAILED DESCRIPTION OF ILLUSTRATIVE MODALITIES Referring now to FIGS. 1 and 2, a balanced interconnector, generally referred to using the reference number 10, will now be described. The interconnector 10 comprises an insulative housing 12 comprising a first external surface 14 in which a first set of turrets "as in 16 were molded and a second external surface 18 in which a second set of turrets was molded as in 20. Note that although the first outer surface 14 and the second outer surface 18 are shown as relatively flat and opposite, in a particular modality, the surfaces could be at an angle to each other, or they could be of unequal height, so that the turrets as in 16, 20, have different relative heights. Referring now to Figures 3 and 4 in addition to Figures 1 and 2, a series of connection elements such as at 22, which extend from one of the first set of turrets at 16 to a corresponding one of the second set of turrets as in FIG. they are included in the housing 12. In this regard, the housing 12 is typically fabricated in a first and second interconnecting portions 24, 26 thereby providing simple means for mounting the connecting elements as in 22 within the housing 12. Each element connection 22 is comprised of a pair of opposite terminals 28, 30, illustratively amplified with each terminal arranged along parallel non-collinear axes. The terminals 28, 30 are illustratively bifurcated Isolation Displacement Connectors (IDC), interconnected by an elongated connection portion 32 at an angle to the terminals 28, 30. Illustratively, the angle between the terminals 28, 30 and the elongated connection portion 32 is shown as being at a right angle. As is known in the art, the IDCs as in 28, 30 are each comprised of a pair of opposite insulation displacement blades at 34. Each element Connection 22 is illustratively stamped into a flat conductive material such as nickel-coated steel, although in a particular embodiment the connection element 22 could be formed in a number of ways, for example as a trace engraved on a Printed Circuit Board (PCB) or the like. Referring still to Figures 1 to 4, the first set of turrets as in 16 and the second set of turrets as in 20, are each arranged in two parallel rows of turrets defining a receiving region of the end of the cable 36 between them for receiving a cable end 38. Insulated conductors as in 40 (typically arranged in twisted pairs of conductors) exit the end of the cable 38 and are received by conductor receiving slots 38 molded in each of the turrets as in 16 or 20. As is known in the art, the insulated conductors as in 40 are inserted into their respective slots as in 42 using a "stamping" tool (not shown) which simultaneously forces the conductor as in between the bifurcated IDCs, interconnecting so both the conductor center 44 of the insulated conductor 34 with the IDC as in 24, 26 cutting at the same time the end of the conductor 40 (typically flush with the outer edge of the turret) in question) . As is known in the art, drivers Isolated as in 40 are typically arranged in twisted pairs of color-coded conductors, and often referred to as Tip and Ring. In twisted pair wiring, the non-intervening wire of each pair is often referred to as the Ring and comprises an external insulator that has a solid color, while the intervening wire is often referred to as the Tip and comprises a white outer insulation which includes a colored strip. Note that although the first set of turrets 16 and the second set of turrets as in 20 in the modality illustrated above are each shown as if they were arranged in two (2) parallel rows of turrets, in a particular embodiment the first set of turrets 16 and the second set of turrets as in 20 could be arranged in a single row, alternatively also along with others, to form the inline cross connector as illustrated in Figure 5. Additionally, systems other than IDCs could be used to interconnect the insulated conductors as in 40 with their respective connection elements as in 22. Referring now to Figures 2 and 4, in a particular embodiment a guide wire cable as in 46, is comprised of a plurality of conductive guide channels like in 48 molded into it and adapted to fit under pressure in the regions receiving the end of the cable as in 36, it can be interposed between the end of the cable 38 and the receiving slots of the conductor 42 molded in each of the turrets as in 16 or 20. Referring now to Figures 2 and 6, As previously discussed the first set of turrets as in 16 and the second set of turrets as in 20 are each arranged in two parallel rows of turrets. As a result, four (4) connection elements are arranged illustratively as in 22 on each side of the receiving region of the cable end 36, each comprising two (2) pairs of interconnects. Illustratively, on a first side of the region receiving the end of the cable 36 four (4) connecting elements 224, 228 and 225, 227 each terminate a respective conductor as in 44 (illustratively the interconnectors are indicated as conductors that end 4, 8, 5 and 7 of the twisted pairs of conductors). Referring now to Figure 7, the connection elements of the "Tip" 224 22e of each interconnector pair are in the foreground "I" and the "Ring" connection elements 225 227 are in the second "II" plane. . Similarly, the connection elements "Tip" 22? 223 are in a third plane "III" and the connection elements "Rings" 222, 226 find in a fourth plane "IV" parallel although displaced from the first plane.

All planes are parallel and are offset from each other. Note that, notwithstanding the previous designation of certain connection elements as in 22 being Punta elements and another being Ring elements as one skilled in the art will comprise the Punta element and Torque and Ring pair could be used to terminate a Ring or Tip of a pair of conductors with the Annular element of the pair of Tip and Ring ending the other. Referring again now to Figure 6 and Figure 7, the direction of the elongated connecting portions 324 328 of the first pair of connecting elements 224 228 is opposite that of the elongated connecting portion 325 327 of the second pair of connecting elements 225. 227 so that the connection elements of Tip and Ring that end in a given twisted pair are arranged opposite each other, like an inverted mirror image. Referring still to Figures 6 and 7, although the connecting elements as in 22 are not directly interconnected with each other, given the relative proximity of the adjacent connecting elements as in 22 with each other, the destructibility of the ends of the cables 38 for inserting the conductors as in 40 in their respective IDC as in 28, 30 gives rise to the parasitic coupling (illustrated by the capacitive elements Cpi and Cp2) between the conductors as in 40, with the effect of being larger than those which are closer (illustratively the drivers marked 4-7 and the drivers marked 5-8). As is known in the art, especially at high frequencies of those couplings although small they can have a large damaging effect on a transmitted signal. In particular, in the illustrated case the differential signals that travel on the pair of conductors marked 7-8 give rise to differential signals on the pair of conductors marked as 4-5 and vice versa. This effect is counteracted by the placement of the interconnects in the manner shown which results in an inherent coupling (illustrated by the first and second capacitive elements Cu and C12) between the connecting elements as in 22 which lie in the same plane. Actually, referring to the first capacitive element Cu, for example, an outer edge 50 of the connecting element 22 ^ provides a first electrode of the first capacitive element Cu, an outer edge 52 of the connecting element 22g provides a second electrode of the first capacitive element Cu and the air between the two electrodes 50, 52 provides the dielectric material of the first capacitive element Cu. The inherent capacitances Cu and C12 effectively cancel the differential mode signals which in other circumstances would be induced in the pair of conductors 404 and 405 by the pair of conductors 407 and 408 and vice versa.

This effect is illustrated in the capacitive network as shown in Figure 9, where both components of the differential signal of conductors 407 and 408 are coupled to each of the conductors 40 < 405 thereby effectively canceling the differential signal. In this way, the inherent capacitors cancel the interference introduced in the conductors 404, 40s, 407 and 40s terminated by, referring to Figure 6 in addition to Figure 9, the connection elements as in 22 by the necessary indestructibility of the twisted pairs of leads 40 for inserting their ends into the bifurcated IDCs 28, 30. Referring now to Figure 10, in an alternative illustrative embodiment of the present invention, the cross connector 10 is comprised of a housing 12 made in the first and second portions of interconnection 54, 56. The first interconnection portion 54 further comprises a series of turrets as in 58 arranged illustratively at the corners of the external surface 60 of the first interconnection portion 54. Similarly, the second interconnection portion 56 also comprises a series of turrets as in 62 arranged illustratively at the corners of the outer surface 64 of the second part of interconnection 54. The substantially flat connection elements as in 22 are arranged in pairs so that the adjacent interconnecting elements as in 22 have their flat sides at right angles to each other. In other aspects, the alternative illustrative embodiment is similar to the first illustrative embodiment as described in detail herein above. Referring now to Figure 11, a first pair "A" of substantially flat connecting elements 22 are arranged on either side and parallel to the "I" plane. Additionally, a second pair "B" of substantially planar connecting elements 22 are arranged on either side and parallel to a plane "II" which intersects plane "I" at right angles. Preferably "II" intersects the "I" plane along a line which coincides with the centers of the first pair A of the connection elements 22, although in a particular embodiment the line of intersection could coincide with another point different from that of the center. This configuration is repeated for the four (4) pairs of connection elements as in 22, ie each pair of connection elements as in 22 is placed at right angles to the adjacent pairs of connection elements as in 22. As result, each pair of connection elements are on either side of a plane which intersects an adjacent pair of connection elements as in 22 and in turn is intersected by the other adjacent pair of connection elements as in 22. Referring now to Figure 12 (a) the indestructibility of twisted pairs of conductors 40 so that they can be inserted between the blades as in 22 of the bifurcated IDCs 28, 30 results in a parasitic coupling, illustrated by the capacitive elements CP4-7, CP4_8, Cp5-7 Cp5-8, between the conductors as in FIG. (again, illustratively the connection elements as in 22 are indicated as conductors terminating 404 40¾ 407 and 408 of the twisted pairs of conductors 40). Referring to Figure 12 (b) in addition to Figure 12 (a) due to the configuration of the parasitic capacitances CP4_7 CP4-8 CP5_7 and Cp5-s- The resulting network inherently cancels the differential mode to differential mode interference and the differential mode to common mode interference. As will now be apparent to one skilled in the art, a differential signal traveling on the conductors 404 and 405 will appear as equal and opposite signals on both conductors 407 and 408 which effectively cancel each other. Actually, the positive phase of the differential signal supported on the conductor 404 is coupled by CP4-7 and CP4-8 on both conductors 407 and 40s- Similarly the negative phase of the differential signal supported on the conductor 405 is coupled by CP5-8 and CP5-7 on both conductors 40 and 0s. Since the parasitic capacitances are substantially equal and the length of the connecting elements such as 22 are much smaller than the wavelength of the signal that is being transmitted (illustratively 650 MHz signals having a wavelength of about 0.46 meters), thus resulting in only minimal phase deviations, the differential signals coupled on the conductors 407 and 4Ü8 by the parasitic capacitances as cross interference effectively cancel each one of them Referring now to Figure 12 (c), given the geometric placement of the connection elements as in 22 one in relation to the other, the above parasitic coupling is repeated for all pairs of conductors terminated in the connection elements as in 22. As a result, balance or equilibrium is provided for all pairs of interconnected elements via the four (4) pairs of connecting elements as in 22. It is to be noted that the balancing or balance is provided regardless of the orientation of the conductors 40 in their interconnection with the connection elements as in 22. That is, for example, the driver designated as 4, which as previously discussed is. generally referred to as the Tip and designated conductor 5, which as discussed above is generally referred to as the Ring of that pair can be exchanged with each other (ie, terminated by the other connecting elements as in 22) without affecting the balance . This applies equally to all pairs of conductors, that is, as illustrated pairs 1-2, 3-6, 4-5 and 7-8.

Referring now to Figure 13 (a), the placement of the connection elements as in 22 also results in an inherent capacitance coupling between the connection elements as in 22, illustrated by the capacitive elements Ci4_7 Cu-e C15-7 and C15-8. Referring to Figure 13 (b) in addition to Figure 13 (a), the distance Dc provided between the centers of adjacent connecting elements as in 22 is substantially greater than the distance Ds separating the interconnectors terminating in a pair of conductors. Particularly (illustratively the distance D is approximately 10 times greater), those inherent capacitances are substantially equal and as a result of a capacitive network which inherently cancels the differential mode to differential mode interference and the differential mode to common mode interference. It should be noted that the capacitive network formed by the inherent capacitances is essentially the same as that of parasitic capacitances as discussed above with reference to Figures 12 (a) through 12 (c) and the above discussion with reference to parasitic capacitances may be applied to the inherent capacitances. Again, given the geometric interrelation between the connection elements as in 22 of different pairs, a similar network of inherent capacitances is formed depending on the orientation, between adjacent pairs of connection elements as in 22.

Referring now to Figure 1 (a), the cross connector 10 is illustratively modular and adapted to be typically assembled together with one or more cross connectors as in 10, in a receptacle machined or otherwise formed in support frames 66, as a Patch fencing panel or similar. In this regard, once the cross connectors as in 10 are mounted on the support frame, a set of turrets is disposed on each side of the support frame 66. Referring now to Figure 1 (b) in addition to the Figure 14 (a), provided that the spacing between adjacent cross connectors as in 10 chooses that the SA separation between the pairs of connecting elements as in 22 of the adjacent cross connectors as in 10, is at least the same as the separations between the pairs of connection elements as in 22 within a cross connector as in 10, the relative geometry between the adjacent pairs of connection elements as in 22 can be maintained between the adjacent cross connector as in 10, so that it achieves the effect of Cancellation of interference. One skilled in the art will understand that the present invention could also be used in conjunction with shielded conductors and cables, for example with the provision of a protective cover (not shown) on the cross connector 10 manufactured for example from a conductive material. interconnected with the protective material that surrounds the conductors / cables. Although the present invention has been described hereinbefore by means of an illustrative embodiment thereof, this embodiment can be modified without departing from the spirit and nature of the objective invention.
