Description

  The present invention relates to balanced interconnectors. In particular, the present invention relates to an interconnector used to interconnect cables containing twisted pair conductors.

  In data transmission networks, cross-connect connectors (BIX, 110, 210, etc.) are typically used to interconnect the ends of telecommunications cables in a telecommunications room to facilitate network maintenance. For example, in the prior art, a series of insulated flat straight lines comprising a pair of IDC (Insulation Displacement Contact) connectors connected end to end to interconnect the conductors of the first cable and the second cable. A cross connector including a conductor is disclosed.

  As is well known in the art, all conductors that transmit signals act as antennas and radiate the signals they carry around them. Other receiving conductors receive this radiated signal as crosstalk. Crosstalk generally has a negative effect on the signal carried by this receiving conductor, and must be addressed if the strength of the received crosstalk exceeds some predetermined minimum. The strength of the crosstalk received is not only the capacitive coupling between the transmitting and receiving conductors (which is affected by many mechanical factors such as the shape of the conductors and the distance between the conductors), but also the conductors carry Depends on signal frequency and conductor shielding. As the signal frequency is increased, even if the value of capacitive coupling is very small, a large crosstalk may occur, which may adversely affect signal transmission.

  Systems designed for the transmission of high frequency signals (such as ubiquitous 4 twisted pair cables according to ANSI / EIA568) use various mechanisms to minimize capacitive coupling between conductors within and between cables. One problem with such a system is that the coupling (and thus crosstalk) is reduced in the cable, but the conductors in the cable must necessarily be terminated, for example, with a device or a cross connector. Such endpoints cause irregularities in the system and increase coupling (and thus crosstalk). With the introduction of Category 6 and Extended Category 6 standards and the 10 GBase-T transmission protocol, all types of internal and external crosstalk, including near-end crosstalk (NEXT), far-end crosstalk (FEXT), and Alien crosstalk are included. The acceptable level is low. As a result, prior art connectors and interconnectors generally cannot meet acceptable levels of crosstalk.

  In addition, long cable elements such as twisted-pair conductors can improve crosstalk characteristics by properly aligning and spacing the conductor pairs, but overall, every time irregularities occur, additional cables are added. Crosstalk occurs. Such irregularities mainly occur at connectors or interconnectors and generally generate strong crosstalk between adjacent pairs of conductors, which degrades the high frequency bandwidth and limits the amount of data transmitted on the conductors. As the transmission frequency increases, the overall irregularity increases each time a small irregularity is added at the local level, which can greatly affect the transmission performance of the cable. In particular, when the ends of the twisted pair conductors are unwound and inserted into an IDC type connection, capacitive coupling is introduced between the twisted pairs.

  To address the shortcomings as described above, a connector is provided for terminating two pairs of conductors. The connector includes first and second elongated terminal pairs, each terminal pair terminating one conductor pair, each first terminal pair being substantially parallel to the first plane and the first plane.

  In the following, referring to FIG. 1 and FIG. 2, a balanced interconnection connector generally indicated by reference numeral 10 will be described. The interconnector 10 includes an insulating housing 12, which has a first outer surface 14 molded therein, such as 16, a first set of turrets, and a second set of turrets, such as 20, formed therein. Second outer surface 18. Although the illustrated first outer surface 14 and second outer surface 18 are relatively flat and facing each other, in some embodiments these surfaces may be at an angle to each other, or the height may be Note that turrets such as 16, 20 may have different relative heights.

  3 and 4 in addition to FIGS. 1 and 2, 22 extends from one of the first set of turrets such as 16 to a corresponding one of the second set of turrets such as 20, etc. A series of connecting elements are embedded in the housing 12. Here, since the housing 12 is generally made of the first and second interconnect portions 24, 26, connection elements such as 22 can be easily incorporated into the housing 12. Each connecting element 22 includes a pair of opposing terminals 28, 30, which are elongated as shown, with each terminal being disposed along a parallel non-collinear axis. In this figure, terminals 28 and 30 are bifurcated insulation displacement connectors (IDCs) that are interconnected by an elongated connection 32 that maintains an angle with respect to terminals 28 and 30. In this figure, the angle between the terminals 28 and 30 and the elongated connection portion 32 is a right angle.

  As is well known in the art, each IDC, such as 28, 30, is provided with a pair of opposing insulating displacement blades, such as 34. Each connecting element 22 is made, for example, by stamping from a flat conductive material such as nickel-plated steel. However, in some embodiments, the connection element 22 may be formed in a number of ways, for example as an etched trace on a printed circuit board (PCB) or the like.

  Still referring to FIGS. 1-4, a first set of turrets, such as 16, and a second set of turrets, such as 20, are each disposed in two parallel rows of turrets for receiving cable ends 38. A cable end receiving region 36 is defined therebetween. Insulated conductors such as 40 (typically twisted pair conductors) exit the cable end 38 and are inserted into conductor receiving slots 38 molded into each turret such as 16 or 20. As is well known in the art, a special “punch down” tool (a tool that simultaneously pushes a conductor such as 40 between the bifurcated IDCs) (not shown) can be used to remove an insulated conductor such as 40 such as By inserting into each slot, the conductive center 44 of the insulated conductor 34 and the IDC such as 24, 26 are interconnected and then the end of the conductor 40 is cut (generally at the same height as the outer edge of the turret).

  As is well known in the art, insulated conductors such as 40 are generally formed of color-coded twisted pair conductors, often referred to as tips and rings. In twisted-pair wiring, each pair of non-inverted wires is often referred to as a ring to provide a single color external insulation, and the inverted wire is referred to as a chip to provide a white external insulation with color stripes. There are many.

It should be noted that while the second set of turrets, such as the first set of turrets 16 and 20 in the exemplary embodiment above, are each illustrated as being disposed in two parallel rows of turrets. In some embodiments, a second set of turrets, such as the first set of turrets 16 and 20, may be arranged in a single row, or along with other turrets in a straight line as shown in FIG. Side-by-side cross connectors may be formed. Further, an insulating conductor such as 40 and each connection element such as 22 may be interconnected using a system other than the IDC.
Referring now to FIGS. 2 and 4, in some embodiments, such as 46 including a plurality of conductor guide channels such as 48 that are molded therein and fit tightly within a cable receiving area such as 36. A wire lead guide may be inserted between the cable end 38 and a conductor receiving slot 42 molded into each turret, such as 16 or 20.

Referring now to FIGS. 2 and 6, as described above, a first set of turrets, such as 16, and a second set of turrets, such as 20, are arranged in two parallel rows of turrets, respectively. To. As a result, four connecting elements such as 22 are arranged as shown on each side of the cable end receiving region 36, each including two pairs of interconnectors. In the figure, the first side of the cable end receiving region 36, in each of four connecting elements ₂₂ 4 to terminate the respective conductors, such as _44, 22 _8, 22 5, 22 ₇ is (figure the interconnector (Shown as terminal conductors 4, 8, 5, 7 of twisted pair conductors)

Referring now to FIG. 7, "chip" connecting elements 22 _4, 22 ₈ of the cross-connector pair is in the first plane "I", "ring" connecting elements 22 _5, 22 ₇ the second plane Within “II”. Similarly, “chip” connecting elements 22 ₁ , 22 ₃ are each in a third plane “III”, and “ring” connecting elements 22 ₂ , 22 ₆ are parallel to the first plane but away from the first plane. In the fourth plane “IV”. All planes are parallel to each other and away from each other. It should be noted that as described above, certain connecting elements such as 22 are referred to as tip elements and other connecting elements are referred to as ring elements, but as those skilled in the art will appreciate, the tip elements of the tip and ring pairs May be used to terminate the ring or tip conductor pair and the ring element of the tip and ring pair to terminate the other.

If in addition to FIG. 7 references the original 6, the direction of the first connecting element pair ₂₂ 4, 22 ₈ elongate connecting portion ₃₂ 4 of 32 ₈ elongate connecting the second connecting element pair ₂₂ 5, 22 ₇ the part 32 _5, 32 ₇ the direction of an opposite, tip and ring connection element to terminate the predetermined twisted pair are arranged opposite one another as a reverse mirror image.

Still referring to FIGS. 6 and 7, connecting elements such as 22 are not directly interconnected with each other, but if adjacent connecting elements such as 22 are relatively close to each other, the end of cable 38 is unwound and a conductor such as 40 is connected. Is inserted into each IDC such as 28, 30, and the like, parasitic coupling (indicated by capacitive elements C _P1 and C _P2 ) occurs between conductors such as 40, and close ones (with conductors indicated by 4-7 in the figure). The influence of the conductor (5-8) is greater. As is well known in the art, such coupling, particularly at high frequencies, can have a significant adverse effect on the transmitted signal, even if small.

More specifically, in the example shown in the figure, a differential signal passing through a conductor pair indicated by 7-8 generates a differential signal on a conductor pair indicated by 4-5. Or vice versa. This effect creates a unique coupling (indicated by the first and second capacitive elements C _I1 and C _I2 ) between connecting elements such as 22 in the same plane by arranging the interconnectors as shown. To cancel. Indeed, referring to the first capacitor element _{C I1,} for example, connecting elements 22 ₄ of the outer edge 50 forms a first electrode of the first capacitor element _{C I1,} the outer edge 52 of the connecting element 22 ₈ first The second electrode of the capacitive element C _I1 is formed, and the air between the two electrodes 50 and 52 forms the dielectric material of the first capacitive element C _I1 .

Intrinsic capacitances C _I1 and C _I2 substantially cancel differential mode signals that would otherwise be induced in conductor pairs 40 ₄ and 40 ₅ by conductor pairs 40 ₇ and 40 ₈ (or vice versa). .
This effect is illustrated by the capacity network of FIG. In this figure, both components of the differential signal conductors 40 ₇ and 40 ₈ so bonded to each of the conductors 40 ₄ and 40 _5, substantially canceling out the differential signal. Thus, conductors 40 ₄ , terminated by connecting elements such as 22 (shown in FIG. 6 in addition to FIG. 9) to unwind the twisted-pair conductor 40 and insert its ends into the bifurcated IDCs 28, 30. Crosstalk introduced into 40 ₅ , 40 ₇ , and 40 ₈ is canceled by the inherent capacitor.

  Referring now to FIG. 10, in another exemplary embodiment of the present invention, the cross connector 10 includes a housing 12 made of first and second interconnect portions 54,56. The first interconnect portion 54 further includes a series of turrets such as 58 disposed as shown in the corners of the outer surface 60 of the first interconnect portion 54. Similarly, the second interconnect portion 56 includes a series of turrets such as 62 arranged as shown in the corners of the outer surface 64 of the second interconnect portion 54. Substantially flat connecting elements such as 22 are arranged in pairs, and the flat sides of adjacent connecting elements such as 22 are perpendicular to each other. In other respects, this other exemplary embodiment is the same as the first exemplary embodiment described in detail above.

  Referring now to FIG. 11, a first pair “A” of substantially flat connecting elements 22 is disposed parallel to both sides of plane “I”. Also, the second pair “B” of substantially flat connecting elements 22 are arranged parallel to both sides of the plane “II” that intersects the plane “I” at right angles. Preferably, plane “II” intersects plane “I” along a line that coincides with the center of the first pair A of connecting elements 22. However, in some embodiments, the line of intersection may coincide at another point other than the center. This configuration is repeated for all four connecting element pairs, such as 22. That is, each connection element pair, such as 22, is at a right angle to an adjacent connection element pair, such as 22. As a result, each connection element pair is on either side of a plane that intersects the plane of an adjacent connection element pair, such as 22, which also intersects the plane of another adjacent connection element pair, such as 22.

Referring now to FIG. 12a, when inserted between the blades such as 34 of IDC28,30 bifurcated by solving the twisted pairs of conductors 40, capacitance elements _C P4-7 between conductors such as _{40, C P4- 8} , C _P5-7 , and C _P5-8 are generated (in this case, connection elements such as 22 are connected to the conductors 40 ₄ , 40 ₅ , 40 ₇ , and 40 ₈ of the twisted-pair conductor 40. Shown as ending). Referring to Figure 12b, in addition to FIG. 12a, the parasitic capacitance _{C P4-7, C P4-8, C P5-7} , by configuring the _{C P5-8,} resulting network is essentially a differential Cancels differential mode that results in mode crosstalk and differential mode that results in common mode crosstalk.

As will be apparent to those skilled in the art, the differential signals traveling on conductors 40 ₄ and 40 ₅ are substantially equal to and opposite to the signals on conductors 40 ₇ and 40 ₈ and thus substantially cancel each other. Indeed, the positive phase differential signal traveling the conductor 40 ₄ is coupled onto the conductor 40 ₇ and 40 ₈ by _{C P4-7} and _{C P4-8.} Similarly, negative phase differential signal traveling conductor 40 ₅ is coupled on the conductor 40 ₇ and 40 ₈ by _{C P5-7} and _{C P5-8.} Each parasitic capacitance is substantially equal and the length of the connecting element such as 22 is much shorter than the wavelength of the transmitted signal (eg, the wavelength of a 650 MHz signal is about 0.46 meters). deviation is very small, the differential signal coupled as crosstalk on the conductor 40 ₇ and 40 ₈ by the parasitic capacitances cancel substantially each other.

  Referring now to FIG. 12c, given the geometric position of connecting elements such as 22 relative to each other, the above parasitic coupling is repeated for all conductor pairs ending with connecting elements such as 22. As a result, all pairs of conductors interconnected via four pairs of connecting elements such as 22 are balanced. It should be noted that this balance is achieved regardless of the orientation of the conductor 40 when interconnected with a connecting element such as 22. Thus, for example, a conductor of 4 commonly referred to as a chip as described above and a conductor of 5 commonly referred to as a pair of rings as described above may be interchanged (ie, other connections such as 22). Does not affect the balance (even if it ends with an element). This applies equally to all conductor pairs (ie pairs 1-2, 3-6, 4-5, 7-8 shown in the figure).

Referring now to FIG. 13a, the positional relationship of the connecting elements such as 22 is also the specific capacitive coupling between the connecting elements such as 22 (capacitance elements C _I4-7 , C _I4-8 , C _I5-7 , C _I5-8 As shown in FIG. Referring to FIG. 13b in addition to FIG. 13a, the distance D _c between the centers of adjacent connecting elements such as 22 is substantially greater than the distance D _S between interconnectors that terminate a conductor pair (in the figure, The distance D is approximately 10 times greater), these intrinsic capacitances are substantially equal, which essentially cancels the differential mode resulting in differential mode crosstalk and the differential mode resulting in common mode crosstalk. Form a capacity network. It should be noted that the capacitance network formed by the intrinsic capacitance is essentially the same as that described above with reference to FIGS. 12a to 12c, and is related to the parasitic capacitance. The above explanation can also be applied to the intrinsic capacitance. Again, given a geometric interrelation between different pairs of connecting elements such as 22, depending on the direction between adjacent connecting element pairs such as 22, a similar network of specific capacitances. Is formed.

  Referring now to FIG. 14a, the illustrated cross connector 10 is modular and within a socket machined or otherwise formed in a support frame 66, such as a patch bay panel. Generally, one or more similar cross connectors, such as 10, are attached together. Here, when a cross connector, such as 10, is mounted on the support frame, a set of turrets are exposed on each side of the support frame 66.

Referring now to FIG. 14b in addition to FIG. 14a, such as 10 between the pairs of connecting elements such as 22 of the adjacent cross connectors distance S _A is between pairs of connecting elements such as 22 in the cross connector such as 10 the distance S _I and by selecting the space between the cross connector adjacent such 10 to be at least the same, the relative arrangement between the adjacent pairs of connecting elements such as 22 canceling the effect of crosstalk can be obtained Can be held between adjacent cross connectors, such as ten.
As will be appreciated by those skilled in the art, the present invention includes, for example, a shielded cover (made of a conductive material and interconnected with a shield material surrounding the conductor / cable) (not shown) on the cross connector 10. It can also be used with conductors and cables.
