Definitions

  • This invention relates to creating a BRAIDED SLEEVE to pull multiple wires and/or fiber optic cables with their multiple connectors already installed on the wires, through electrical conduits, conduits, drywalls, and anywhere else, without the risk to damage the already installed connectors and/or pull the wires and/or fibers disrupting their proper functionality during the cable pulling installation process.
  • the present invention is directed to create a BRAIDED SLEEVE to wrap multiple wires and/or fibers out of a single whole cable with their connectors already installed, and pull the cable through drywalls, electrical conduits, conduits, and anywhere else, in a way which protects the wires and connectors during the pulling process without damages.
  • a cable with multiple wires and connectors already installed is very difficult to pass through anywhere, as these multiple wires and preinstalled connectors will get stuck at the first turn of the electrical conduit, or ever worse if there are already other wires inserted into the same conduits.
  • This invention creates a BRAIDED SLEEVE, long as needed and wide as needed to insert the connectors with their wires of a finished cable and make a pullable wrap of it, you can pull with a fish tape.
  • the braided sleeve is THERMO-WELDED with the shape of an arrow tip, so it will open and pass through any crowd of pre existing cables, as well will drive the whole cable trough the pipe or conduit or drywall.
  • Kevlar or Nylon fibers are not available coming out from the cable rubber or main connector, these holes cab host a ZIP-TIE or similar to close the braided sleeve before the rubber of the first connector of the cable, so when the braided sleeve will be pulled using the FISH TAPE it will pull the first connector rubber which is secured internally to the main connector and to the internal Kevlar or nylon every pullable cable has.
  • the SPMCC Braided invention When pulled via the fish tape, the SPMCC Braided invention will SQUEEZE the inside the braided sleeve wrapped connectors and wires as slim as possible The more you pull the braided sleeve, the more the braided sleeve nylon net will squeeze the inside.
  • the SPMCC braided sleeve When pulled with the Fish Tape, the SPMCC braided sleeve will remain very flexible, slim, and will follow the rout of the pipe or conduit or drywall holes with minimal friction, and turning as needed, because the nylon net of the braided sleeve is very flexible at all times
  • the SPMCC braided sleeve can remain installed on the cable, and can have an internal plastic foil to pre-wrap the connectors, so the whole cable head and connectors stays protected from humidity, stucco, paint and any other construction material or dust.
  • FIG. 1 Shows an example of a multi-connector / multi wire cable that usually would not pass through electrical conduits, ordrywalls, or anywhere, also subject to damages if pulled as these many connectors and wires might get stuck and get damaged.
  • FIG.2 Shows as a multi wires / multi connector cable can be pre-wrapped in plastic foil to protect the connectors and wires from construction sites humidity, paint, dust, stucco, etc. This pre-wrapping protect the connectors from rust, humidity, and any other external agent anywhere.
  • the SPMCC braided sleeve will be secured to the main cable via a zip-tie before the first connector rubber, so when you pull the SPMCC braided sleeve using a fish tape, you pull the main connector rubber which is already secured inside to fhe connector shell where the cable is locking the inner Kevlar or nylon, typical on pullable cables
  • FIG.3 (C) Shows the SPMCC BRAIDED NYLOG NET SLEEVE, ready to insert the plastic pre-wrapped cables and connectors
  • FIG.4 Shows the SPMCC Braided Sleeve inserted on top of the multi-wires and connector cable, ready to be pulled with a fish tape through any electrical conduit, or conduits, or drywalls, or anywhere.
  • the SPMCC sleeve When used in new constructions sites, the SPMCC sleeve can stay installed at all times, protecting the innerwires and connectors from any STUCCO, PAINT, WET, HUMIDITY, DUST, HURTS, ETC

Abstract

Gaine (SPMCC) pour gainer des câbles électriques et/ou de fibres optiques de manière à réduire au minimum leur taille globale dans un boîtier qui reste mince, flexible et robuste pour tirer et faire passer des câbles dans des conduits électriques, des parois sèches, et n'importe où, sans endommager les multiples connecteurs dans le processus de traction.
