, Description:FOUR U FILLER
TECHNICAL FIELD
[0001] The present disclosure, relates to the field of telecommunication cables. More particularly, the present disclosure relates to a Four U shaped filler for use in a telecommunications cable for high speed data transmission applications.
BACKGROUND
[0002] With the growth in use of sophisticated computer devices for communication applications, the demand for transmitting data at higher speeds has increased. Nowadays, various data cables are utilized for communication applications which are compliant with high performance data standards. One such type of data cables is a Category 6A U/UTP (Unshielded Twisted Pair) cables. The UTP cables are easy to handle, install, terminate and use. Typically, these UTP cables include multiple twisted pairs of insulated conductors. In addition, these UTP cables include filler or a separator. Typically, the shape of the filler may be cross type filler. The filler or separator forms four regions for disposing the twisted pair of insulated conductors. Specifically, each twisted pair of insulated conductor is disposed in a corresponding region formed by the separator such that each pair of conductor is isolated from another. Moreover, the prior art cable designs include a jacket. The jacket surrounds the filler and the insulated conductors. The filler provides protection against near end crosstalk between the pairs of insulated conductors in the data cable.
[0003] In one of the prior art with patent number US8030571 B2, a telecommunications cable is provided. The telecommunications cable includes four twisted pairs of insulated conductors. In addition, the telecommunications cable includes a separator configured to provide four quadrants in the telecommunications cable. The four twisted pairs of insulated conductors are individually disposed within the four quadrants of the separator. Moreover, the telecommunications cable includes a cable jacket. The cable jacket surrounds the four twisted pairs of insulated conductors and the separator along the length of the telecommunications cable. The separator is double H shaped filler. In addition, the separator includes a central portion, a first side portion and a second side portion. The central portion is shorter in size than the first side portion and the second side portion. The non-uniform size of the separator affects the electrical performance of the telecommunications cable. Further, the separator includes a first horizontal portion and a second horizontal cross portion. The first horizontal portion and the second horizontal cross portion are perpendicular to the central portion. However, the first horizontal portion and the second horizontal cross portion are staggered or offset or dislocated from each other. Furthermore, the separator is made of a material having a material with a dielectric constant substantially the same to a dielectric constant of material used for insulation of the conductor. Further, the conventional Category 6A U/UTP cables with cross shaped filler have several drawbacks. The shape of the cross filler is non-uniform. The non-uniform shape of the cross filler leads to difficulty in confinement of the twisted pairs of insulated conductors within the area enclosed by different regions of the cross shaped filler. In addition, the position of the twisted pairs of insulated conductors is not fixed which affects the electrical performance of the cable. The shape of the cross filler fails to provide protection against cross talk from other similar designed cables when laid down together. Further, the production speed of the data cable is low due to large number of variations in the lay length of the twisted pairs of conductors. Furthermore, the conductors are prone to be displaced from their position during bending or installation due to shape of the conventional shaped cross filler.
[0004] In light of the above stated discussion, there exists a need for a telecommunications cable which overcomes the above cited drawbacks of conventionally known telecommunications cable.
OBJECT OF THE DISCLOSURE,
[0005] A primary object of the disclosure is to provide a telecommunications cable with Four U shaped filler.
[0006] Another object of the present disclosure is to provide the telecommunications cable with uniform shaped filler.
[0007] Yet another object of the present disclosure is to provide the telecommunications cable with reduced alien cross talk.
[0008] Yet another object of the present disclosure is to provide the telecommunications cable with high flame resistance.
[0009] Yet another object of the present disclosure is to provide the telecommunications cable with lower smoke generation.
[0010] Yet another object of the present disclosure is to provide the telecommunications cable filler with zero halogen and low smoke material.
[0011] Yet another object of the present disclosure is to provide the telecommunications cable with higher machine speed on buncher during production of the telecommunications cable.
[0012] Yet another object of the present disclosure is to provide the telecommunications cable with firm positioning of twisted pair of insulated conductors.
