Description

Technical Field

[0001] The utility model relates to the technical field of optical cable reinforcement cores, in particular to an optical cable reinforcement core stripping device. Background Art

[0002] Fiber optic cables (optical fiber cables) are manufactured to meet optical, mechanical, or environmental performance specifications. They are communications cable assemblies that utilize one or more optical fibers enclosed in a sheath as the transmission medium and can be used individually or in groups. Fiber optic cables primarily consist of optical fibers (hair-thin glass filaments) protected by a plastic sheath and outer jacket. Optical cables contain no metals such as gold, silver, copper, or aluminum and are generally not worth recycling. Optical cables are communications lines composed of a number of optical fibers arranged in a specific pattern, surrounded by a sheath, and sometimes even an outer sheath, to transmit optical signals. Specifically, they are cables formed from optical fibers (the optical transmission medium) through a specific process. The basic structure of an optical cable generally consists of a core, reinforcing steel wires, fillers, and a sheath. Additionally, waterproof layers, buffer layers, and insulated metal conductors may be added as needed. Existing optical cables often incorporate a reinforcing core to enhance cable strength, protect the internal optical fibers from external forces, and maximize protection for the optical fibers within the cable.

[0003] At present, during the installation and maintenance of optical cables equipped with reinforcing cores, the sheaths on the cables need to be stripped off. However, the existing stripping method usually involves manually using a knife to strip the sheaths on the optical cables. This is not only inefficient, but also because the knife is dangerous, it is very easy to cause damage to the hands of the staff during direct use, which is not conducive to use. For this reason, we propose an optical cable reinforcing core stripping device. Utility Model Content

The sheath of the optical cable reinforcement core yarn tube is stripped by setting the stripping assembly.

[0008] Furthermore, the extrusion assembly includes an internal threaded ring and an extrusion ring. The surface of the external threaded ring is threadedly connected to the internal threaded ring. The left end of the internal threaded ring is fixed with an extrusion ring. All the oblique blocks are fitted with the inner wall of the extrusion ring.
