Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cold-resistant, moisture-proof and ant-rat-proof cable. Background Technique

[0002] A cable is usually a rope-like cable formed by stranding several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The whole is wrapped with a highly insulating covering layer. It is mostly erected in the air, installed underground or underwater for telecommunications or power.

[0003] The utility model with the authorization announcement number CN213339755U discloses a cable, including an outer protective layer and a cross-shaped frame strip. The cross-shaped frame strip is fixedly arranged inside the outer protective layer. Four installation cavities are formed between the cross-shaped frame strip and the outer protective layer. A skeleton strip is installed in the installation cavity. Core wires are clamped between two clamping strips on the skeleton strip. A flame retardant layer is filled in the installation cavity. The outer protective layer is successively provided with a tensile layer and an outer surface layer from inside to outside. Grooves are arranged along the circumferential direction on the outer surface layer. An elastic layer is arranged in the grooves. Although the device can better stabilize the core wires by filling a flame retardant layer in the installation cavity and play a flame retardant effect at the same time, the cold resistance and moisture resistance of the cable of this device are poor, so that the cable cannot be applied to different conditions, and it is not convenient to prevent and control rats and ants, so that the cable is easily bitten by mice or termites, resulting in cable failures and low practicability. Therefore, we provide a cold-resistant, moisture-proof and ant-rat-proof cable to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a cold-resistant, moisture-proof and ant-rat-proof cable.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cold-resistant, moisture-proof and ant-rat-proof cable, including a support frame, a protection mechanism is arranged above the support frame. The protection mechanism includes a protection layer. An armor layer is fixedly installed on the inner wall of the protection layer. A high-temperature resistant layer is fixedly installed on the inner wall of the armor layer. A cold-resistant layer is fixedly installed on the inner wall of the high-temperature resistant layer. A waterproof layer is fixedly installed on the inner wall of the cold-resistant layer. A filling layer is fixedly installed on the inner wall of the waterproof layer. Six cable conductors are arranged inside the filling layer.

[0006] Furthermore, a shielding layer is fixedly installed on the outer surface of each cable conductor, and a wear-resistant layer is fixedly installed on the outer surface of the protection layer.

[0007] Furthermore, an insulating layer is fixedly installed on the outer surface of each shielding layer, and the outer surface of each insulating layer is fixedly connected to the inner wall of the filling layer.

[0008] Furthermore, a reinforcing core is fixedly installed on the outer surfaces of the six insulating layers, and the outer surface of the reinforcing core is fixedly connected to the inner wall of the filling layer.

[0009] Furthermore, a limiting frame is movably hinged to the upper surface of the support frame, and a first rubber plate is fixedly installed on the inner wall of the limiting frame.

[0010] Furthermore, a second rubber pad is fixedly installed on the inner wall of the support frame, and the outer surface of the second rubber pad is in contact with the outer surface of the wear-resistant layer.

[0011] Furthermore, two connecting blocks are fixedly installed on both side surfaces of the support frame, and a connecting hole is formed in the upper surface of each connecting block.

[0012] Furthermore, limiting blocks are fixedly installed on the left side surfaces of the limiting frame and the support frame, and a limiting hole is formed in the upper surface of each limiting block.

[0013] Compared with the prior art, the cold-resistant, moisture-proof, anti-rat and anti-mouse cable has the following beneficial effects:

[0014] 1. By providing an armored layer, the tensile strength and compressive strength of the cable can be enhanced. The armored layer is made of a steel wire armored layer with a high magnetic permeability, which has a good magnetic shielding effect and can be used to resist low-frequency interference, improving the anti-interference performance of the cable. The high-temperature resistant layer is made of fluoroplastics, which has excellent weather resistance, heat resistance, a small friction coefficient, stable chemical properties, and good electrical insulation properties. The cold-resistant layer is a PTFE tape, which has a low density, low dielectric loss, and is less affected by temperature and data signal frequency changes. The waterproof layer is an aluminum-polyethylene composite tape, which has a high water tightness, making the waterproof performance stronger. The filling layer is petroleum jelly, which has a high melting temperature, appropriate hardness, viscosity, and good low-temperature toughness, playing a role in moisture-proof and insulation, increasing the cold resistance and moisture-proof of the cable, and enabling the cable to be applicable to different conditions.

[0015] 2. By providing a protective layer, the cable conductor can be protected. The protective layer is formed by adding a rat and ant repellent to the polyolefin cable sheath material through multiple composites, making the outer sheath of the cable contain a pungent and unpleasant smell. When rats and ants come into contact with the cable, they will be repelled due to the stimulation of their sense of smell and will also send a message of non-contact to the group, resulting in a group effect, avoiding cable failures caused by rats or termites gnawing on the cable, and thus achieving the purpose of protecting the cable from being damaged by rats and ants, and achieving a strong practical effect.

The outer surface of the first rubber plate 213 is in contact with the outer surface of the wear-resistant layer 209. The limit frame 212 facilitates the support and installation of the cable, and the first rubber plate 213 can protect the protection layer 201, increasing the practicality of the cable.

[0024] Referring to Figure 2 and Figure 3, an anti-freezing layer 205 is fixedly installed on the inner wall of the high-temperature resistant layer 204, a waterproof layer 206 is fixedly installed on the inner wall of the anti-freezing layer 205, a filling layer 207 is fixedly installed on the inner wall of the waterproof layer 206, six cable conductors 202 are arranged inside the filling layer 207, a shielding layer 208 is fixedly installed on the outer surface of each cable conductor 202, a wear-resistant layer 209 is fixedly installed on the outer surface of the protective layer 201. The wear-resistant layer 209 can increase the abrasion resistance of the cable. The material of the wear-resistant layer 209 is chloroprene rubber, which has high strength, good durability, excellent abrasion resistance, good elasticity, and is resistant to impact and vibration.

[0025] Refer to Figure 2 and Figure 3 , an insulating layer 210 is fixedly installed on the outer surface of each shielding layer 208, and the outer surface of each insulating layer 210 is fixedly connected to the inner wall of the filling layer 207. The insulating layer 210 can protect the shielding layer 208 from mechanical damage, chemical corrosion, contact with water vapor and moisture, and prevent electric shock when contacting conductors, etc., which can enhance the mechanical strength and extend the service life.

[0026] Refer to Figure 2 , a strengthening core 211 is fixedly installed on the common outer surface of the six insulating layers 210, and the outer surface of the strengthening core 211 is fixedly connected to the inner wall of the filling layer 207. The strengthening core 211 can improve the radial tensile strength of the cable and the anti-bending performance of the cable, and further increase the practicality of the cable.

[0027] Refer to Figure 1 and Figure 4 , a second rubber pad 214 is fixedly installed on the inner wall of the support frame 1, and the outer surface of the second rubber pad 214 is in contact with the outer surface of the wear-resistant layer 209. The second rubber pad 214 can protect the wear-resistant layer 209 and prevent the support frame 1 from affecting the wear-resistant layer 209, increasing the convenience of the cable.

[0028] Refer to Figure 1 , two connecting blocks 215 are fixedly installed on both side surfaces of the support frame 1, and a connecting hole 216 is formed on the upper surface of each connecting block 215.

[0030] Working principle: By means of the strengthening core 211, the radial tensile strength and bending resistance of the cable can be improved. The armor layer 203 can enhance the tensile strength and compressive strength of the cable. The armor layer 203 is made of steel wire and has a high magnetic permeability, with a good magnetic shielding effect, which can be used to resist low-frequency interference and improve the anti-interference performance of the cable. The high-temperature resistant layer 204 is made of fluoroplastic. Fluoroplastic has excellent weather resistance, heat resistance, a small friction coefficient, stable chemical properties, and good electrical insulation properties. The cold-resistant layer 205 is made of PTFE raw tape, with a low density, low dielectric loss, and is less affected by temperature and data signal frequency changes. The waterproof layer 206 is made of aluminum-polyethylene composite tape, which has a high water tightness, making the waterproof performance stronger. The filling layer 207 is made of petroleum jelly. This material has a high melting temperature, appropriate hardness, viscosity, and good low-temperature toughness, playing a role in moisture-proof and insulation, increasing the cold resistance and moisture-proof performance of the cable, enabling the cable to be applicable to different conditions. The protective layer 201 can protect the cable conductor 202. The protective layer 201 is made by adding a rat and ant repellent to the polyolefin cable sheath material through multiple composites, making the outer sheath of the cable contain a pungent and strange smell. When rats and ants come into contact with the cable, they will be disgusted with the contact because their sense of smell is stimulated, and at the same time, they will send a message of non-contact to the group to produce a group effect, avoiding cable failures caused by rats or termites gnawing on the cable, so as to achieve the purpose of protecting the cable from being damaged by rats and ants. Through the support frame 1 and the limiting frame 212, it is convenient to install the cold-resistant, moisture-proof, ant- and rat-proof cable, making the cold-resistant, moisture-proof, ant- and rat-proof cable more practical.
