Description

A general rubber sheathed cable

Technical field:

The utility model relates to the field of cables, in particular to a universal rubber-sheathed cable.

Background technique:

Cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. It is usually a rope-like cable twisted by several or several groups of wires, at least two in each group. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation. layer.

General-purpose rubber-sheathed cables are mainly suitable for various mobile electrical equipment and line networks such as household appliances and power tools with AC rated voltages up to and including 450/750V. The allowable operating temperature of the wire core is not greater than 65 degrees Celsius.

For traditional general-purpose rubber-sheathed cables, when used in various mobile electrical equipment and line networks, they are subjected to large mechanical external forces, and core breakage often occurs; when used outdoors or in places exposed to oil, often due to waterproof, The oil resistance is poor and the life of the cable is relatively short.

Utility model content:

The purpose of the utility model is to provide a universal rubber-sheathed cable, which has a reasonable structural design and can effectively improve the mechanical performance, waterproof and oil resistance of the cable.

The technical scheme of the utility model is as follows:

A general-purpose rubber-sheathed cable, including three main conductors and sub-conductors, the outer sides of the three main conductors and sub-conductors are all wrapped with an insulating layer, and it is characterized in that: the finished characters of the three main conductors wrapped with the insulating layer are distributed in a Y shape On the outside of the support frame, the Y-shaped support frame is formed by extruding tear-resistant silicone rubber. The secondary conductor is located in the center of the Y-shaped support frame. The legs of the Y-shaped support frame are respectively provided with aramid reinforcements. The body, the secondary conductor and the supporting frame form a cable core, the cable core is wrapped with a waterproof tape, the waterproof tape is covered with a metal tube, and the metal tube is extruded and formed with a sheath layer.

The general-purpose rubber-sheathed cable is characterized in that: the sheath layer is formed by extruding rubber.

The utility model has the advantages of:

The utility model has a novel structure. The secondary conductor is designed in the support frame among the three main conductors. At the same time, the end of each leg of the support frame is provided with an aramid fiber reinforcement, which improves the structural compactness and external extrusion resistance of the cable. At the same time The cable also has properties such as moisture resistance and oil resistance, which prolongs the service life of the cable.
