Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a low-voltage cable. Background Technology

[0002] Low-voltage cables refer to cables used for security communication, electrical equipment, and related low-voltage transmission applications. There is no strict distinction between "electric wires" and "cables." Generally, products with fewer cores, smaller diameters, and simpler structures are called electric wires; those without insulation are called bare wires, and others are called cables. Conductor cross-sectional areas with larger cross-sectional areas (greater than 6 square millimeters) are called large wires, and those with smaller cross-sectional areas (less than or equal to 6 square millimeters) are called small wires. Insulated wires are also called building wires.

[0003] Because low-voltage cables are widely used, many office network cables have multiple cables with the same path. If a cable management device is used, it needs to be fixed, which can easily lead to holes being made on the desktop or floor, and it is also inconvenient to separate them later.

[0004] Therefore, it is necessary to provide a new type of low-voltage cable to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a low-voltage cable.

[0006] The low-voltage cable provided by this utility model includes:

[0007] The cable sheath and the cable core disposed therein, wherein the top side of the cable sheath is provided with a plurality of annularly distributed arc-shaped grooves, and the bottom side of the cable sheath is fixedly fitted with a plurality of annularly distributed plastic columns.

[0008] Both sides of the arc-shaped groove are fitted with side protrusions distributed along the axial direction of the cable sheath, and the bottom wall of each side protrusion is fixedly fitted with several rubber strips.

[0009] Preferably, one-third of the plastic column is fitted into the cable sheath.

[0010] Preferably, the cross-section of the arc-shaped groove is a two-thirds circular structure, and the arc-shaped groove matches the plastic column.

[0011] Preferably, the number of arc-shaped grooves and plastic columns is the same.

[0012] Preferably, the plastic post at the bottom of the cable sheath has a through cavity.

[0013] Preferably, the cable core is fitted with an insulation layer, and the insulation layer is fitted with an epoxy resin glass fiber layer.

[0014] Preferably, a shielding layer is provided on the epoxy resin glass fiber layer, and the shielding layer is made of semiconductor paper.

[0015] Preferably, the shielding layer is embedded in the cable sheath.

[0016] Compared with related technologies, the low-voltage cable provided by this utility model has the following advantages:

[0017] 1. When multiple low-voltage cables have the same connection path, this utility model arranges the cable sheaths to fit together, so that the plastic posts on the sides of the cable sheaths engage in the arc-shaped grooves inside the adjacent cable sheaths. The remaining low-voltage cables are engaged in the same way in sequence, so that multiple low-voltage cables can be fixed together, which facilitates the arrangement of low-voltage cables and improves their aesthetics. When winding up the cable, the cable sheath itself can be wound up, so that the plastic posts engage in the arc-shaped grooves, thereby improving the stability of the cable winding.

[0018] 2. The rubber strip provided in this utility model not only protects the cable sheath, but also sweeps away dust from the surface of the cable sheath by swinging the rubber strip, thus improving the cleanliness of the cable sheath. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 2 The present invention provides a low-voltage cable, which includes: a cable sheath 1, a cable core 2, and a plastic post 3.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 2The cable sheath 1 contains a cable core 2, an insulation layer is fitted on the cable core 2, an epoxy resin glass fiber layer 6 is fitted on the insulation layer, and a shielding layer 7 is fitted on the epoxy resin glass fiber layer 6. The shielding layer 7 is made of semiconductor paper and is embedded in the cable sheath 1.

[0026] It should be noted that the epoxy resin glass fiber layer 6 has good insulation performance and is heat-resistant and corrosion-resistant, increasing the service life of the cable. The shielding layer 7 ensures that the signal quality of the low-voltage cable will not be reduced due to external interference, further improving the transmission function of the low-voltage cable.

[0027] In the embodiments of this utility model, please refer to Figure 1 The top side of the cable sheath 1 is provided with a plurality of annularly distributed arc-shaped grooves 1a, and the cross-section of the arc-shaped grooves 1a is a two-thirds circular structure. The bottom side of the cable sheath 1 is fixedly fitted with a plurality of annularly distributed plastic columns 3, and one-third of the column body of the plastic column 3 is fitted into the cable sheath 1.

[0028] It should be noted that when multiple low-voltage cables have the same connection path, the cable sheaths 1 are arranged in a way that the plastic posts 3 on the side of the cable sheath 1 engage with the arc grooves 1a inside the adjacent cable sheaths 1. The remaining low-voltage cables are engaged in the same way, so that multiple low-voltage cables can be fixed together, which facilitates the arrangement of low-voltage cables and improves their aesthetics.

[0029] When winding up the cable, the cable sheath 1 can be wound up by itself, so that the plastic column 3 is engaged in the arc groove 1a, thereby improving the stability of the cable winding.

[0030] The plastic column 3 at the bottom of the cable sheath 1 has a through cavity 3a to facilitate the pressing of the plastic column 3 so that the plastic columns 3 on both sides can be engaged into the arc groove 1a.
