the subject cable will be described with reference to a balanced electrical system , specifically a telephone system , installed in an area not having conduits but where it is desired to have inconspicuous wiring , for example , where it is desired to run cable through a carpeted area without leaving a tell - tale lump . it is also desired that the cable be so constructed as to not only be inconspicuous but to not be readily damaged by furniture and traffic while still providing good electrical characteristics . this is accomplished by the present invention in a manner not previously contemplated by the prior art discussed above . the subject cable is shown in an exemplary embodiment in fig1 with cables 10 , 12 running from a panel 14 , under carpeting 16 , to housings 18 where they are connected to the cable 20 of a conventional telephone desk set 22 . the cables are terminated , see fig2 and 3 , by known connectors , such as the amp champ connectors mentioned previously . each connector 24 has a plurality of contacts 26 mounted therein . each contact of the connector has a conductor engaging portion defining an insulation piercing slot . the cable is forced against the contacts which pierce the insulation and engage the conductors . the cable is then held in the connector by a strain relief member 28 which is clamped over the rear part of the connector housing and exerts a compressive force on the cable 10 . three embodiments of cable according to the present invention are shown in fig4 to 6 . in each case the cable is an assembly of two identical cable members , each comprising a plurality of conductors bonded to an insulating carrier . the cable of fig3 has a plurality of parallel , spaced round conductors 30 , 32 embedded between two layers of flexible plastic insulation material 34 , 36 , 38 , 40 to define two cable members 42 , 44 which are secured together by an adhesive ( not shown ). the cable of fig5 is similar to the cable of fig4 except that flat conductors 46 , 48 are embedded in layers 50 , 52 , 54 , 56 of insulation material to form cable members 58 , 60 which are secured together by an adhesive ( not shown ). the cable of fig6 has a plurality of conductors 62 , 64 bonded in respective profiled molded plastic backing members 66 , 68 with the two cable members being secured together by a single adhesive layer 70 which also acts as an insulator between the individual conductors of each of the cable members . fig7 shows how the cable of fig6 would be open to provide access to the conductors . the conductors are bonded to their respective insulating carrier members with an adhesive which has a greater affinity for the conductor than for the plastic or adhesive inner layer between the cable members . thus the carrier members can be readily separated without displacing the conductors . it should also be noted that the adhesive inner layer 70 does not extend to both marginal edges of the members 66 , 68 thus providing an easy way to separate the members . in this regard the invention contemplates that the bond between insulating cover members may be continuous or periodic across or along the interior or facing surfaces of the members . this may be accomplished by lines or dots of adhesive on the interior surfaces of the members or on the interlayer . alternatively , such bond may be accomplished with heat selectively applied to the cable . the important point is that the cable carrier members be held together in such fashion as to provide a substantially constant and uniform spacing between the conductors of the respective cable members which are designated as being a conductor pair . it is contemplated that the separation of the cable members be accomplished by a peeling operation or a slitting operation . either peeling or slitting could take place at the ends of the cable or intermediate the ends to effect a t top of the cable . fig8 shows a schematic of a flat cable formed in accordance with the prior art . conductors 72 , 74 , respectively , are designated the tip and ring conductors of a driven pair and conductors 76 , 78 , respectively , comprise the tip and ring conductors of a quiet pair . it will be noted that a total of four capacitances 80 , 82 , 84 , 86 will develop between the respective conductors of the pairs . because of the unbalance of these capacitances , crosstalk will occur through capacitive coupling between the respective pairs . the present invention is schematically shown in fig9 wherein the capacitances have been shown rearranged in a balanced bridge arrangement . the conductors of the present cable are so spaced within each cable member and between two cable members such that the product c a c b is substantially equal to the product c c c d . thus as this equality is approached , the capacitive crosstalk will approach zero thereby effecting an overall improvement in the cable crosstalk characteristics , as the capacitive coupling in this type of cable is normally orders of magnitude higher than the inductive coupling . as a specific example , a cable was constructed having a plurality of number 26 guage awg conductors with a center - to - center spacing of 0 . 085 &# 34 ; within each cable member and a center - to - center spacing between conductors of the cable members of 0 . 025 &# 34 ;. the cable was 10 feet long and was inserted into a 600 ohm balanced to ground system . when a 1 khz signal was applied to this cable , the crosstalk attenuation was measured at better than 100 db . it should be noted that crosstalk in short run low frequency telephone circuits has been found to be principally due to capacitive coupling between the conductors forming the cables . flat cable has capacity between the driven and quiet pairs as shown above and it is the object of the present invention to make these capacities substantially equal . it should further be noted that the present invention is suitable for use only in a balanced system such as found in telephone systems and would not usually or necessarily hold true for an unbalanced system such as used in the computer industry . in general telephone usage , such as the above exemplary embodiment , the conductors are arranged in a plurality of pairs with the conductors of each pair termed ring and tip and these or other terms may be employed to identify selected conductors in the cable . in general the spacing between conductors of a given pair is dependent upon a choice of dielectric or geometry of insulating material with some spacing being held to practical limits of manufacture . this spacing can be on the order of between 0 . 001 &# 34 ; to 0 . 010 &# 34 ; with an improvement in crosstalk attenuation proportional to such spacing as limited by the capacitive loading of the pairs on the system . as an alternative to the above - discussed embodiments , the conductors of one layer can be slightly offset with respect to the conduct in the adjacent layer . for example , as shown in fig1 , cable members 84 , 86 have conductors 88 , 90 , respectively fixedly embedded in insulation 92 , 94 . the cable members are then permanently joined together with the conductors 88 , 90 laterally offset a distance &# 34 ; d &# 34 ;. it has been found that when cable members having 0 . 020 inch diameter solid wire on 0 . 085 inch horizontal and 0 . 030 inch vertical centers are assembled with a &# 34 ; d &# 34 ; of 20 to 35 mils , a further reduction in the capacitive crosstalk of up to 20 db and a further reduction in the total crosstalk up to 13 db can be realized . a further alternative for reducing crosstalk in cables of the present type is to interleave a high dielectric constant material between the rows . this is shown in fig1 , wherein a layer 96 of dielectric material , such as barium titanate well mixed with poly vinyl chloride , is positioned between two cable members 98 , 100 . the effect of this additional layer is to increase the diagonal capacitance with a minimal effect on the horizontal capacitance . thus , a closer capacitance balance can be realized . this embodiment is particularly useful when a minimum vertical spacing must be maintained . it also has the advantage of spreading the rows of conductors whereby termination of the cable will be facilitated , particularly with a slitting operation . for this reason it is also foreseen that the cable could be produced with pockets or pillows of high dielectric constant material therein at regular spaced intervals . the present invention may be subjected to many changes and modifications without departing from the spirit or essential characteristics thereof . the present embodiments are therefore intended in all respect as being illustrative and not restrictive of the scope of the invention .
