Description

Technical Field

[0001] This utility model belongs to the field of adhesive-insulated wire technology, specifically relating to an adhesive-insulated wire with high compressive strength. Background Technology

[0002] Rubber-insulated wires typically refer to electrical wires or cables with a rubber insulation layer, primarily used for transmitting electrical energy or signals while ensuring electrical safety and mechanical performance during use.

[0003] When rubber-insulated wires are used, their solid internal structure results in poor compressive strength. During installation, the wires may be squeezed by external objects, and the rubber insulation layer on the outside cannot provide cushioning or protection. This can damage the internal conductors, affecting the normal use of the wires and causing inconvenience to operators.

[0004] Therefore, this utility model provides a rubber-coated wire with high compressive strength to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber-insulated wire with high compressive strength, aiming to solve the problem in the prior art that when the rubber-insulated wire is laid, it may be squeezed by external objects, and the rubber insulation layer on the outside of the rubber-insulated wire cannot play a buffering and protective role, which may cause damage to the internal conductors of the rubber-insulated wire after being squeezed, thus affecting the normal use of the rubber-insulated wire.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure-resistant rubber-coated wire, comprising a connecting rod, three sets of spacers connected in a circular array on the outer surface of the connecting rod, the other end surface of the spacers being connected to the inner surface of a protective shell, three sets of conductors arranged in a circular array inside the protective shell, an arc-shaped pressure-resistant block surrounding the outer surface of the protective shell, the other end surface of the arc-shaped pressure-resistant block being in contact with the inner surface of the armor layer, and a rubber-coated layer surrounding the outer surface of the armor layer.

[0007] As a preferred embodiment of the high-pressure-resistant rubber-coated wire of this utility model, a filler adhesive is provided between the conductor and the spacer plate, and the filler adhesive is made of vulcanized rubber.

[0008] As a preferred embodiment of the high-compression-resistant rubber-coated wire of this utility model, the connecting rod, the spacer plate, and the protective shell are all made of low-density polyethylene.

[0009] As a preferred embodiment of the high-pressure-resistant rubber-coated wire of this utility model, the arc-shaped pressure-resistant block is made of rubber, and the armor layer is made of galvanized steel wire.

[0010] As a preferred embodiment of the present invention, which provides a high-compression-resistant rubber-coated wire, a protective layer is connected around the outer surface of the rubber coating layer, and the outer surface of the protective layer is connected with protrusions in a ring array.

[0011] As a preferred embodiment of the high-compression-resistant rubber-coated wire of this invention, the protective layer and the bump are made of silicone rubber.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention utilizes the cooperation of connecting rods, spacers, protective shells, filler adhesive, arc-shaped pressure-resistant blocks, and armor layers. When the insulated wire is squeezed by an external object, the armor layer deforms under the pressure of the external force. At this time, the armor will squeeze the arc-shaped pressure-resistant block, causing the two ends of the arc-shaped pressure-resistant block to expand outward and deform. This can effectively buffer and disperse the pressure, allowing the protective shell to effectively protect the wire, thereby enhancing the pressure resistance of the insulated wire.

[0014] This invention features a protective layer and protrusions. When the insulated wire is laid, the protrusions will first rub against external objects. Only after the protrusions are worn will they rub against the protective layer, thereby improving the service life of the protective layer and ensuring the wear resistance of the insulated wire.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figs. 1-3 The present invention provides the following technical solution: a high-pressure-resistant rubber-coated wire, including a connecting rod 1, three sets of spacers 2 connected in a ring array on the outer surface of the connecting rod 1, the other end surface of the spacers 2 being connected to the inner surface of the protective shell 3, three sets of conductors 4 arranged in a ring array inside the protective shell 3, an arc-shaped pressure-resistant block 6 being connected around the outer surface of the protective shell 3, the other end surface of the arc-shaped pressure-resistant block 6 being in contact with the inner surface of the armor layer 7, and a rubber-coated layer 8 being connected around the outer surface of the armor layer 7.

[0022] Preferably, a filler 5 is provided between the conductor 4 and the spacer 2, and the filler 5 is made of vulcanized rubber.

[0023] In practical use, the filler 5 can tightly fill the gap between the wire 4 and the spacer 2, which can fix the position of the wire 4. At the same time, the vulcanized rubber has high elasticity and can undergo elastic deformation when subjected to external pressure, and return to its original shape after the pressure is removed. In this way, the filler 5 can further buffer the residual pressure.

[0024] Preferably, the connecting rod 1, the spacer 2, and the protective shell 3 are all made of low-density polyethylene.

[0025] In practical applications, low-density polyethylene has a low density, which makes the connecting rod 1, spacer 2 and protective shell 3 made of it lighter, reducing the overall weight of the circuit. In addition, low-density polyethylene has good flexibility, which allows the insulated wire to be bent and twisted to a certain extent without damaging the internal structure.

[0026] Preferably, the arc-shaped anti-compression block 6 is made of rubber, and the armor layer 7 is made of galvanized steel wire.

[0027] In practical use, the rubber has good elasticity and cushioning properties, allowing the arc-shaped pressure-resistant block 6 to absorb and disperse pressure through its own deformation when the rubber-coated wire is subjected to external pressure, reducing the impact of pressure on the internal conductor 4 and other structures, and effectively improving the pressure resistance of the rubber-coated wire. The galvanized steel wire has high strength and hardness, so the armor layer 7 can initially resist external forces with the high strength of the galvanized steel wire, providing reliable mechanical protection for the rubber-coated wire.

[0028] Preferably, a protective layer 9 is connected around the outer surface of the adhesive layer 8, and protrusions 10 are connected in a ring array on the outer surface of the protective layer 9.

[0029] In practical use, when the insulated wire is being laid, the protrusions 10 on the outside of the protective layer 9 will first rub against external objects. Only after the protrusions 10 are worn will they rub against the protective layer 9, thereby improving the service life of the protective layer 9 and ensuring the wear resistance of the insulated wire.

[0030] Preferably, the protective layer 9 and the bump 10 are made of silicone rubber.

[0031] In practical applications, silicone rubber can maintain the stability of its physical and chemical properties over a wide temperature range, giving the protective layer 9 and bumps 10 good wear resistance, reducing wear on the rubber-coated wire during use, and extending its service life.

[0032] Working principle: When manufacturing this high-compression-resistant rubber-insulated wire, the conductor 4 is placed in the space separated by the spacer 2 and the protective shell 3. Filler 5 is then filled into the protective shell 3, filling the gaps between the spacer 2, the protective shell 3, and the conductor 4, thus fixing the conductor 4 in place. Then, an arc-shaped compression-resistant block 6 is placed around the outer surface of the protective shell 3, and an armor layer 7 is used to wrap around the arc-shaped compression-resistant block 6. Next, the rubber-insulated layer 8 and the protective layer 9 with protrusions 10 are sequentially installed, completing the fabrication of the rubber-insulated wire. When the rubber-insulated wire is subjected to external pressure, the armor layer 7 initially resists the external force with the high strength of the galvanized steel wire. After deformation, the armor layer 7 transfers the pressure to the arc-shaped compression-resistant block 6. At this time, the rubber arc-shaped pressure-resistant block 6 deforms by expanding outward at both ends, using its good elasticity to buffer and disperse the pressure, greatly reducing the pressure intensity transmitted to the protective shell 3. The protective shell 3 is stably supported by the connecting rod 1 and the spacer plate 2 made of low-density polyethylene, which can ensure that the protective shell 3 can maintain its shape under the remaining pressure, thereby reliably protecting the internal conductor 4. This setting can enhance the pressure resistance of the rubber-insulated wire. Secondly, when the rubber-insulated wire is laid, the protrusions 10 on the outside of the protective layer 9 will first rub against the external object. Only after the protrusions 10 are worn will they rub against the protective layer 9, thereby improving the service life of the protective layer 9 and ensuring the wear resistance of the rubber-insulated wire during long-term use.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
