Description

anti-rat cable

technical field

The utility model relates to a cable, in particular to a rodent-proof cable.

Background technique

At present, most of the information exchange in the society needs to be transmitted through wires and cables, and the anti-destructive requirements of wires and cables are becoming more and more stringent, especially for modern intelligent buildings and today's information highways, the safety requirements of cables are even higher. is particularly important. Among them, with the development of modern electric power, communication and power transmission, preventing rats from biting and destroying is a key point of cable safety work, especially cables for nautical ships, wires and cables for cities or railways (including: power cables, control cables , signal cables, communication cables, computer instrumentation cables and equipment and equipment lines) have shifted from high-altitude erection to underground burial development. The gnawing of cables by mice can cause communication disconnection in light cases, and fires in severe cases, affecting people's lives and property.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mouse-proof cable with good mouse-proof effect and simple structure.

The purpose of the invention of the utility model is achieved in the following way: a rodent-proof cable, which includes a cable body wrapped with a sheath layer, characterized in that: the sheath layer is provided with a rodent-proof coating.

For the further refinement of the rodent-proof cable described in the present invention, the inner cavity of the sheath layer is sequentially provided with a metal shielding layer, an insulating layer, a conductor shielding layer and a metal guide core from outside to inside.

For the above-mentioned anti-rat cable, the inner cavity of the sheath layer may be provided with an armor layer, a tape layer and a core layer sequentially from the outside to the inside, and the core layer is formed by splicing several wires.

For further refinement of the above technical solution, the wire is composed of a wire shielding layer, a wire insulation layer and a metal core arranged in sequence from outside to inside.

For a further refinement of the above technical solution, the core layer is covered with a filling layer, and the filling layer is arranged between the core layer and the wrapping layer.

Compared with conventional cables, the utility model has the following advantages:

The utility model improves the traditional cable. A rodent-proof coating is provided outside the sheath layer of the cable body. The rodent-proof coating can be a preparation layer with a mouse-repelling smell, or the rodent-repellent can be added to the resin coating Outside the sheath layer, the above-mentioned anti-rodent coating can also be coated on the surface of the conventional cable protective layer. When the mice touch or prepare to bite the cable, the anti-rodent coating can stimulate or repel the mice, so as to achieve the effect of anti-rodent Effect, and, this kind of cable structure is simple, is beneficial to production, and new cable preparation or old cable can be produced or transformed into the structure described in the utility model, has greatly improved the anti-rodent effect of cable.

Accompanying drawing 2 is the sectional structural drawing (remove section line) of the utility model embodiment 2.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

According to Fig. 1 and Fig. 2, the anti-rodent cable described in the utility model includes a cable body wrapped with a sheath layer 1, and the sheath layer 1 is made of semi-rigid flame-retardant PVC. Vinyl resin is obtained by adding plasticizers, stabilizers and flame retardants, etc. through extrusion molding. It is easier to use than rigid ones, and it also has a certain anti-rat effect. In the rodent-proof cable described in the utility model, the sheath layer 1 is provided with a rodent-proof coating 12 outside. The rodent-proof coating 12 can be a preparation layer with a mouse-repelling smell, and the preparation with the rodent-repelling smell can stimulate the oral mucosa and gustatory nerves of the mice, making them detest the biting of the cable. Preparations of cycloheximide, R55 rat-repellent, ziram, thiram, thiram, basic thiourea, tricyclic tin, N-dioxoacetyl-4-tert-butylcyclohexylamine or antibiotics, etc. etc., this type of preparation can be directly sprayed on the outside of the sheath layer 1 of the cable to form the rodent-proof coating 12. This preparation method has a relatively simple process and is widely used. In addition, the above-mentioned rodent-proof coating 12 can also be mixed with resin to form the above-mentioned rodent-proof coating. This structure is suitable for the preparation of new cables; The anti-rodent coating 12 is formed on the periphery of the jacket layer 1 . In the cable of the present invention, it can be made into the following two embodiments:

Embodiment 1: See Figure 1

For the inner cavity of the sheath layer 1 described in the utility model, a metal shielding layer 2, an insulating layer 3, a conductor shielding layer 4 and a metal guide core 5 are arranged in sequence from the outside to the inside, and the cable with this structure is a single-core cable , the structure is relatively simple, and can be applied to ordinary electric wires.

Example 2: See Figure 2

For the above-mentioned rodent-proof cable, the inner cavity of the sheath layer 1 may be provided with an armor layer 6, a tape layer 7 and a core layer in sequence from the outside to the inside, and the core layer is spliced by several wires. The wire is composed of a wire shielding layer 8, a wire insulating layer 9 and a metal core 10 arranged in sequence from outside to inside. For the further refinement of the above technical solution, the core layer is covered with a filling layer 11, and the filling layer 11 is arranged between the core layer and the tape layer 7. The cable with this structure is an armored multi-core cable.

The utility model is equipped with a rodent-proof coating 12 outside the sheath layer 1 of the cable body. When the mouse touches or prepares to bite the cable, the rodent-proof coating 12 can stimulate or repel the mouse, so as to realize the rodent-proof effect , and, this kind of cable structure is simple, is beneficial to production, and new cable preparation or old cable can be produced or transformed into the structure described in the utility model, has improved the anti-rodent effect of cable greatly.
