Waterproof cable for sea fishing

Technical Field

The utility model belongs to the technical field of the cable technique and specifically relates to a sea is angled and is used waterproof cable.

Background

The applications of the electric wire and the electric cable are mainly divided into three main categories, namely an electric power system, an information transmission system, mechanical equipment and an instrument system. The electric wire and cable products adopted by the electric power system mainly comprise overhead bare wires, bus bars (buses), electric power cables, rubber sleeve cables, overhead insulated cables, branch cables (replacing part of buses), electromagnetic wires, electric equipment wires and cables for electric power equipment and the like. The electric wire and cable used for the information transmission system mainly include a local telephone cable, a television cable, an electronic cable, a radio frequency cable, an optical fiber cable, a data cable, an electromagnetic wire, an electric power communication or other composite cables and the like. Almost all other products except an overhead bare wire in mechanical equipment and instrument and meter systems are applied, but mainly comprise a power cable, an electromagnetic wire, a data cable, an instrument and meter cable and the like.

The electric wire and cable products are mainly divided into five major categories, namely bare wires and bare conductor products, electric power cables, electric wire and cables for electrical equipment, communication cables, optical fibers and electromagnetic wires. The power cable is mainly characterized in that the conductor is externally extruded (wound) with an insulating layer, such as an overhead insulated cable, or several-core twisted (corresponding to a phase line, a zero line and a ground wire of a power system), such as an overhead insulated cable with more than two cores, or a sheath layer is added, such as a plastic/rubber-sheathed wire cable.

With the common application of digital electronic products, the fishing mode is changed from floating watching to visible fishing, a wire is required to be used as a fishing line and also used as a wire to be connected with an underwater camera, the cable is required to have a waterproof effect and can bear larger pulling force, and particularly, the pulling force of the cable is required to be 60-70 kilograms during sea fishing. The existing waterproof cable for sea fishing can meet the requirement on waterproof effect, but is not enough in the strength direction.

In order to solve the technical problem, the purpose of the utility model is to realize like this:

the utility model relates to a sea fishing waterproof cable, which comprises a TPU resin layer arranged on the outer side, and a set number of nickel-molybdenum alloy wires, a set number of copper wires and a Kevlar filament arranged inside the TPU resin layer; the nickel-molybdenum alloy wires, the copper wires and the Kevlar filaments are twisted.

On the basis of the above scheme and as a preferable scheme of the scheme: the thickness of the TPU resin layer is 0.2 mm.

On the basis of the above scheme and as a preferable scheme of the scheme: the number of the copper wires is 8, the copper wires are twisted, and the diameter of the copper wires is 0.08 mm.

On the basis of the above scheme and as a preferable scheme of the scheme: the number of the nickel-molybdenum alloy wires is 4, the nickel-molybdenum alloy wires are twisted, and the diameter of the nickel-molybdenum alloy wires is 0.08 mm.

On the basis of the above scheme and as a preferable scheme of the scheme: the fineness of the Kevlar filament is 3000D.

On the basis of the above scheme and as a preferable scheme of the scheme: and a PVC resin layer is arranged on the outer side of the copper wire.

The utility model has the advantages that: the utility model relates to a sea is angled and is used waterproof cable has used TPU resin to make the skin can play good waterproof and prevent the effect that the sea water corrodes. The nickel-molybdenum alloy wires and the Kevlar filaments arranged in the cable can greatly increase the relay of the cable, and the tensile force of 90 kilograms can be achieved through tests, which is far higher than the standard requirement.

Detailed Description

The present embodiment will now be described in detail with reference to the drawings attached to the specification hereinafter. In the drawings, embodiments of the invention are shown, however, the invention may be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein.

Unless otherwise defined, terms (including technical and scientific terms) used herein should be understood to have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Moreover, it will be understood that terms used herein are to be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
