Definitions

  • the present invention relates to an unshielded twisted pair (UTP) cable assembly, and specifically a UTP cable assembly having a structure capable of preventing cross talk between wire pairs to improve its transmission property.
  • UTP unshielded twisted pair
  • the UTP cable is an unshielded twisted pair widely used to construct a communication network such as LAN, which includes wire pairs (P), each having two insulator-coated wires 10, 11 twisted in a spiral manner as shown in Fig. 1.
  • wire pairs P
  • at least two cables C are assembled as a bundle as shown in Fig. 2.
  • a conventional bundle-type UTP cable has a disadvantage of inducing alien cross talk that an electromagnetic field induced in wires of each single UTP cable gives electromagnetic influences on other adjacent UTP cables due to its structure that adjacent cables are contacted with each other.
  • a conventional UTP cable assembly has a problem that the inherent pitch arranged in of a cable pair at opposite locations or the aggregated pitch of twisted wire pairs are designed to have the same length in each UTP cable, so the alien cross talk between the UTP cables becomes worse.
  • a UTP cable arranged in the center of the cable assembly is severely electromagnetically affected from other cables in all directions, and such a severe electromagnetical influence acts as a noise in the signal transmission system, eventually causing a communication disorder.
  • the present invention is designed to solve the problems of the prior art, and it is an object of the present invention to provide a UTP cable assembly having a structure capable of preventing the generation of cross talk between internal wire pairs of the UTP cable, adjacent to each other.
  • the present invention provides a UTP (Unshielded Twisted Pair) cable assembly, which includes at least two UTP cables, in each of which wire pairs, each having two insulator-coated wires twisted in a spiral manner, are aggregated in a sheath; and a web member interposed between the UTP cables to interconnect the adjacent UTP cables and keep a space between the adjacent UTP cables, wherein the web member has a width of 0.2 mm to 2.0 mm.
  • UTP Unshielded Twisted Pair
  • a width of the web member functions to minimize cross talk between the UTP cables and to keep an optimum space therebetween. At this time, if the web member has an extremely small width, it is difficult to dismantle the UTP cable assembly, causing damage of the cables, while, if the web member has an extremely large width, it is difficult to keep an optimum space between the UTP cables. Accordingly, The width of the web member may be preferably set to the range of 0.2 mm to 2.0 mm, more preferably 0.8 mm to 1.2 mm.
  • the wire pair has a minimum pitch value of about 8 mm and a maximum pitch value of about 20 mm to satisfy cross talk property and other properties in the 4-pair single UTP cable.
  • the pitch values of the remaining two wire pairs in the 4-pair single UTP cable are further determined within the range between the maximum and minimum pitch values. Pitch combinations among four wire pairs in the single UTP cable determined as above thus satisfy electric properties of each single UTP cable.
  • Each single UTP cable should satisfy electric properties even if a web member is interposed between the UTP cables to keep a space between at least two UTP cables.
  • the wire pairs arranged in corresponding locations in the UTP cables preferably have different pitch values.
  • the difference of the pitch values between the corresponding wire pairs preferably has a value of 0.2 mm or more.
  • the difference of pitches between the four wire pairs is preferably 0.5 mm to 7.5 mm, more preferably 1.0 mm to 7.0 mm.
  • a cross filler may be further inserted in the sheath of the UTP cable in a length direction to isolate the wire pairs from each other.
  • the UTP cable assembly includes at least two UTP cables, in each of which wire pairs, each having two insulator-coated wires twisted in a spiral manner, are aggregated in a sheath; and a web member interposed between the UTP cables to interconnect the adjacent UTP cables and keep a space between the UTP cables and having a width of 0.2 mm to 2.0 mm, wherein the wire pairs in each UTP cable are twisted at regular aggregation pitches, and aggregation pitches of the adjacent UTP cable have different lengths.
  • the aggregation pitch is preferably 50 mm to 200 mm, more preferably 70 mm to 150 mm.
  • aggregation pitches of wire pairs in an odd number group or in an even number group preferably have the same length, respectively.
  • a cross filler may be further inserted in the sheath of the UTP cable in a length direction to isolate the wire pairs from each other.
  • the web member is preferably made of polyvinyl chloride (PVC) or low smoke zero halogen (LSZH) materials, with its width of 0.2 mm to 2.0 mm, more preferably 0.8 mm to 1.2 mm.
  • PVC polyvinyl chloride
  • LSZH low smoke zero halogen
  • Fig. 3 is a cross sectional view showing a UTP cable assembly according to one embodiment of the present invention.
  • the UTP cable assembly includes at least two UTP cables C1, C2, each having a plurality of wire pairs P1 to P8 therein, and a web member 103 interposed between adjacent UTP cables C1, C2.
  • the order of the wire pairs P1 to P8 shows in each single UTP cable P1 ⁇ P4 and P5 ⁇ P8 that P1 and P5 correspond to the shortest pitches and P4 and P8 correspond to the longest pitches, respectively. And, the order of their lengths is applied to every single UTP cable identically.
  • the UTP cable C1, C2 is configured so that a plurality of wire pairs P1 to P8, each having two insulator-coated wires 100 and 101 twisted in a spiral manner, are aggregated in a sheath 102.
  • the web member 103 is interposed between the UTP cables C1, C2 to connect the adjacent UTP cables C1, C2 to each other.
  • the web member 103 also keeps a space between the UTP cables C1, C2 so as to prevent alien cross talk.
  • the web member 103 has a web structure easily torn to facilitate dismantling operation of the cable, and is preferably formed of polyvinyl chloride (PVC) or low smoke zero halogen (LSZH) materials.
  • PVC polyvinyl chloride
  • LSZH low smoke zero halogen
  • the shape of the web member 103 may be variously modified, not limited to one shown in the figures.
  • the width W of the web member 103 may be preferably set to 0.2 mm to 2.0 mm, more preferably 0.8 mm to 1.2 mm, to keep an optimum space between the UTP cables C1, C2 and also to minimize the cross talk.
  • the pitches of wire pairs arranged at the corresponding positions like P1 and P5, or P4 and P8, preferably have different lengths to minimize an electromagnetic interaction between the pairs.
  • the difference of pitches between the corresponding wire pairs is preferably maintained to 0.2 mm or larger to prevent the electromagnetic interaction.
  • the difference of pitches between the wire pairs is preferably maintained in the range of 0.5 mm to 7.5 mm, more preferably 1.0 mm to 7.0 mm, to minimize the electromagnetic interaction.
  • the number of wire pairs is not limited to this embodiment but may be variously modified.
  • a cross filler 104 is inserted in a length direction in the UTP cable C1, C2 having four wire pairs so as to isolate the wire pairs from each other and prevent the cross talk between the pairs.
  • the cross filler 104 is provided with 4 bulkheads crossing with each other so as to bar interaction between the wire pairs.
  • the aggregation pitches of wire pairs in an odd number group or in an even number group preferably have same length.
  • the wire pairs in the UTP cables C1, C2 may be aggregated with being twisted with each other at regular aggregation pitches. That is to say, the UTP cable C1 is configured so that the wire pairs P1 to P4 are spirally twisted with each other at regular aggregation pitches, and the UTP cable C2 is configured so that the wire pairs P5 to P8 are spirally twisted with each other at regular aggregation pitches.
  • the aggregation pitches of the UTP cables C1 and C2 preferably have different lengths to prevent the cross talk between the wire pairs. It is because that the electromagnetic interaction is inversely proportional to the distance between the wires.
  • the aggregation pitches of the wire pairs are identical to each other, the space between the corresponding pairs of the respective UTP cables are kept regularly, which may maximize influence of the alien cross talk between the pairs.
  • the aggregation pitches of the UTP cables C1, C2 may be set in the range of 50 mm to 200 mm, more preferably 70 mm to 150 mm, for more effective prevention-of the cross talk.
  • the web member is interposed between the UTP cables to connect the adjacent UTP cables to each other, and simultaneously to prevent alien cross talk with keeping a space between the UTP cables.
  • the web member has a web structure easily torn to facilitate dismantling operation of the cable, and is preferably formed of polyvinyl chloride (PVC) or low smoke zero halogen (LSZH) materials.
  • PVC polyvinyl chloride
  • LSZH low smoke zero halogen
  • the shape of the web member may be variously modified, not limited to one shown in the figures.
  • the width W of the web member 103 may be preferably set to 0.2 mm to 2.0 mm, more preferably 0.8 mm to 1.2 mm, to keep an optimum space between the UTP cables and also to minimize the cross talk.
  • Fig. 4 shows an embodiment where four UTP cables C1 to C4 are connected in series. If at least 4 UTP cables are connected in series as shown in Fig. 4, respective pitches and aggregation pitches of the wire pairs in an odd number cable group (see C 1 and C3) or in an even number cable group (see C2 and C4) have the same lengths, while the pitches in adjacent cable groups preferably have different lengths to prevent the cross talk between the wire pairs P1 to P16.
  • Fig. 5 shows an embodiment to which conditions for keeping a regular space between UTP cables and conditions for optimizing their pitches as mentioned above are applied.
  • a regulated value P20 of the alien cross talk regulated in IEC61156-5 and a measurement value of each cable are depicted.
  • UTP cables are interconnected with an optimum space by means of the web member 103, so the wire pairs of adjacent UTP cables are not electromagnetically affected from each other and therefore the alien cross talk is prevented.
  • the present invention may prevent the generation of alien cross talk between wire pairs and allow manufacture of standardized UTP cable assemblies because a space between the UTP cables may be kept optimally.
  • the present invention ensures easy dismantling of cables under construction since UTP cables keep a constant space by means of a web structure that is easily torn.
  • the present invention may provide a UTP cable assembly having optimized pitch conditions to minimize electromagnetic interaction between wire pairs.
  • the present invention as mentioned above may be very usefully used for a 10-gigabit transmission network as a signal transmission system of a communication cable using copper, which requires prevention of alien cross talk.
