Document Type and Number:
WIPO Patent Application WO/2021/262153
Kind Code:
A1
Abstract:
SPMCC is the invention of a sleeve to wrap electrical and/or fiber optic cables in a way to minimize their overall size into a package which remain slim and flexible and robust to pull and pass into electrical conduits, drywalls, and anywhere else, without damaging the multiple connectors in the pulling process.

CLAIMS:

1) SPMCC is the invention of sleeve to wrap a multi wire multi connector electrical and/or fiber cable, so it cab be pulled and pass through electrical conduits, drywalls, and anywhere else, without damaging the multiple connectors or wires.

2) A sleeve can be done off any material, such as braided nylon which is very resistant, not stretching when you pull it, and because it is a braided pattern it will “ squeeze “ whatever is inside the braided sleeve

3) The SPMCC Braided sleeve is open on one side to insert the wires with their connectors, and it is sealed on the other side, thermo-welded with the sha e of an arrow head to pass easy through crowded pipes.

4) The head of the SPMCC Braided sleeve has also a Thermo-Welded Hole to attach a FISH TAPE to pull the cable

5) The open side of the SPMCC Braided Sleeve has some thermo-welded holes to pass-through and make a knot with the KEVLAR or NYLON fiber coming out from the main cable, so when you pull the SPMCC braided sleeve, it will squeeze the inserted wires and connectors making them the slimmest as possible, and will pull the whole cable via its internal anti-stretch Kevlar or nylon, so the wires and connectors will never be subject to any pull force and will stay protected during the process within the Braided SPMCC braided sleeve.

Description:
BACKGROUND OF THE INVENTION:

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.

SUMMARY OF THE INVENTION:

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.

On the head side, 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.

On the head-side of the SPMCC Braided sleeve there is also a Thermo-Welded Hole to attach to the FISH TAPE to pull the sleeve

On the open side of the SPMCC braided sleeve there are other Thermo-Welded holes needed to secure the braided sleeve to the cable by making a knot with the KEVLAR or NYLON fibers coming out from the cable

If 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.

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.

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

In case of new construction sites, 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.

When the construction is completed, the electrician will cut the Kevlar or fiber knot, or the zip-tie, removing the SPMCC braided sleeve, removing the inner plastic foil, revealing the connectors and wires in perfect untouched conditions, ready to connect to the WALL PLATE KEYSTONES or to anywhere. BRIEF DESCRIPTION OF THE DRAWINGS:

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.

(a) The same cable as per FIG.1 now is pre-wrapped into a plastic protection foil.

(b) In this example some KEVLAR fibers do exit on purpose from the cable main connector rubber, and will be used fo secure the SPMCC Braided Sleeve to the cable with a KEVLAR KNOT

If no Kevlar or nylon fibers are available, 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

• (D) Shows the open side of the SPMCC Braided sleeve where to insert the wires and connectors into the Braided Sleeve.

• (E) Shows the “ head “ side of the SPMCC braided sleeve, Thermo welded with the shape of an arrow tip, to drive the cable pulling though crowded conduits and anywhere

• (F) Shows the Thermo-Welded Hole where to attach the FISH TAPE to pull the cable

• (G) Shows two Thermo-Welded holes passing from both sides of the braided sleeve, where to install the ZIP-TIE to close and secure the SPMCC Braided sleeve before the first main connector rubber, or to make the knot using the kevlar fiber or nylon coming out on purpose from the main connector rubber when using cables specifically created for this.

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.

• (H) Shows the knot done with the Kevlar fibers on the SPMCC braided sleeve to secure the sleeve to the cable, so when the Braided Sleeve will be pulled with a FISH TAPE, the braided sleeve with transfer all the pulling force to the Kevlar fiber, pulling the whole cable, without applying any force to the connectors and wires inside the SPMCC braided sleeve, so the inner wires and connectors will stay protected and safe from any force, or any obstruction eventually found during the pulling process

• 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

Only at the end of the construction cycle, the electrician will cut the knot, remove the SPMCC Braided Sleeve, remove the prewrapping plastic foil, and reveal and use the inner wires and connectors which stayed protect for the whole time.
