Definitions

  • the present invention relates to a support collar for cables, tubes or the like.
  • the supporting of cables or pipes in the telecommunications and building sector is achieved by using one or more support collars that can be fixed on perforated plates.
  • Support collars in fact comprise relatively elastic structures obtained by means of respective open profiles, which can be splayed to be rapidly fitted onto the cables or tubes to be supported.
  • a support collar comprising a laminar structure provided with a flat head portion with a central opening, two side portions extending transversely from said head portion and each having a coupling element suitable for engaging said collar on a support plate or a flat head portion of a further support collar, a retaining clip for a long-shaped article positioned in the area determined by said head portion and said two side portions.
  • Said retaining clip is formed from the structure of a respective side portion of the collar.
  • passive intermodulation takes place when various radiofrequency signals, coming from one to several radio base stations, mix together in a site that houses a cell, giving rise to a signal that contains a new set of frequencies.
  • Undesired signals due to passive intermodulation are generated due to some form of mechanical non-linearity.
  • One of the major causes is the inconsistency of the contacts between metal and metal in the areas affected with high current intensities, such as those inside the transmission lines or within the radiofrequency (RF) components. This may be due to the imperfect preparation of the RF terminations or non-optimal assembly procedures, loosening of screws or rivets inside the RF components, contaminated or oxidized surfaces of the connectors or RF connectors that are not properly tightened.
  • Passive intermodulation can therefore potentially considerably degrade the quality of the service of new networks, for example Lte (Long Term Evolution) and Hdspa+ (High Speed Downlink Packet Access), and it is of primary importance for telecommunications operators to reduce the negative effects of passive intermodulation in order to be able to install more advanced network infrastructures capable of supporting the transporting of broadband data, without a significant increase in costs and without jeopardizing the performance level.

  • Hdspa+ High Speed Downlink Packet Access
  • the objective of the present invention is to provide a support collar for cables, pipes or the like capable of solving the problems described above.
  • the objective of the present invention is to provide support collars with an elastically deformable structure and suitable for supporting cables having different geometries and sections, i.e. cables whose thicknesses vary from narrow cross-sections to wide sections.
  • a further objective of the present invention is to provide stackable support collars which are easy to position along the longitudinal development of the cables or pipes and which guarantee the stable locking of cables and pipes, or the like.
  • Another objective of the present invention is to reduce the production and marketing costs of support collars. Yet another objective of the present invention to provide support collars which can eliminate the problem of the passive intermodulation phenomenon.
