Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a wear-resistant and oil-resistant multi-core cable for machine tools. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wire and an insulation layer, and are used to connect circuits, electrical appliances, etc.

[0003] Some cables need to work in special environments. For example, cables used on machine tools are used in oily environments and often move back and forth. Therefore, the cables need to have high oil resistance, wear resistance and toughness. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wear-resistant and oil-resistant multi-core cable for machine tools in view of the above shortcomings.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A wear-resistant and oil-resistant multi-core cable for machine tools, comprising a central core wire, multiple peripheral core wires, an outer shielding layer, an armoring layer, and an outer sheath. The multiple peripheral core wires are spirally wound around the outer side of the central core wire, and a reinforcing wire is provided in the gap between the peripheral core wires and the central core wire. All the core wires are enclosed in an outer shielding layer, the outer side of the outer shielding layer is enclosed by an inner sheath, the outer side of the inner sheath is enclosed by an armoring layer, and the outer side of the armoring layer is enclosed by an outer sheath.

[0007] The core wire comprises a conductor, an insulating layer and an inner shielding layer, and the outer side of the conductor is covered with the insulating layer and the inner shielding layer in sequence.

[0008] Furthermore, the gap between the outer shielding layer and the core wire is filled with fireproof material.

[0009] Furthermore, the inner shielding layer is made of aluminum foil.

[0010] Furthermore, the outer shielding layer is a tinned copper braided tape.

[0011] Furthermore, the armor layer is a steel wire wrapped layer.

[0012] Furthermore, the outer protective layer is made of polyurethane rubber.

[0013] Furthermore, the reinforcement wire is a steel wire.

[0014] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0015] This cable features multiple cores spirally wound around a central core, with reinforcing wires inserted in the gaps, enhancing the overall structural strength of the cable. The armor layer is wrapped with steel wire, further improving the cable's mechanical strength and tensile strength. Through its multi-layered design and the enhanced protection of the armor layer, particularly the oil- and wear-resistant polyurethane rubber outer sheath, the cable effectively resists oil corrosion and frequent physical wear in machine tool environments, extending its service life.

[0023] like Figure 1-2As shown, a wear-resistant and oil-resistant multi-core cable for machine tools includes a central core wire, multiple peripheral core wires, an outer shielding layer 4, an armor layer 6, and an outer sheath 7. The multiple peripheral core wires are spirally wound around the outer side of the central core wire. A reinforcement wire 8 is provided in the gap between the peripheral core wires and the central core wire. All core wires are enclosed in an outer shielding layer 4. The outer side of the outer shielding layer 4 is enclosed by an inner sheath 5. The outer side of the inner sheath 5 is enclosed by an armor layer 6. The outer side of the armor layer 6 is enclosed by an outer sheath 7.

[0024] The core wire includes a conductor 1, an insulating layer 2 and an inner shielding layer 3. The outer side of the conductor 1 is covered with the insulating layer 2 and the inner shielding layer 3 in sequence.

[0025] As an embodiment, the gap between the outer shielding layer 4 and the core wire is filled with a fireproof material 9.
