Abstract

A reinforced cable tie generally includes an elongate strap having a first end, a second end and an elongate planar strap body therebetween, a head having an upstanding central wall separating a first and a second elongate parallel passageway through the head for respective receipt of the first and second ends of said strap, a locking device supported in the head for retaining the first and second ends of the strap and a continuous reinforcement disposed in and extending substantially continuously along a path defining the strap. In a method for forming a cable tie, a continuous reinforcing strand is co-extruded within an elongate strap and a head is assembled to the strap.

First claim

What is claimed is:

1. A cable tie comprising:
an elongate strap having a first end, a second end and an elongate planar strap body therebetween;
a head having an upstanding central wall separating a first and a second elongate parallel passageway through said head for respective receipt of said first and second ends of said strap;
a locking device supported by said central wall, said locking device being configured to permit said first and second ends of said strap to be respectively inserted through said first and second passageways of said head in a first direction and being further configured to prevent movement of said first and second ends of said strap from said respective head passageways in a second direction opposite said first direction; and
a continuous reinforcement disposed in and extending substantially continuously along a path defining said strap,
wherein said head comprises a continuous fiber reinforcement structure and is separately attachable to said strap.

2. The cable tie as defined in claim 1 , wherein said continuous reinforcement is co-extruded with said strap.

3. The cable tie as defined in claim 1 , wherein said continuous reinforcement comprises a glass fiber.

4. The cable tie as defined in claim 1 , wherein said continuous reinforcement comprises a metallic strand.

5. The cable tie as defined in in claim 1 , wherein said continuous reinforcement is disposed centrally within said strap.

6. The cable tie as defined in claim 1 , wherein said continuous reinforcement comprises glass, aramid, carbon, metal, basalt, polybenzimidazole, natural fibers, carbon nanotubes, graphene, or any combination thereof.

7. The cable tie as defined in claim 1 , wherein said continuous reinforcement comprises bundles of filaments, twisted cords, twisted ropes, single filaments, woven sheets, tapes, meshes, ladder-like structures or perforated sheets.

8. The cable tie as defined in claim 1 , wherein said head is attachable to said strap during installation of the cable tie.

9. The cable tie as defined in claim 1 , wherein said strap comprises an extrudable thermoplastic.

10. The cable tie as defined in claim 9 , wherein said extrudable thermoplastic comprises nylon, acetal, or polypropylene.

11. The cable tie as defined in claim 1 , wherein a percentage by weight of said continuous reinforcement content with respect to said strap is between 1% and 30%.

12. The cable tie as defined in claim 1 , wherein the overall thickness of the strap and the continuous reinforcement disposed therein is between 0.3 mm and 3 mm.
