Description

Technical Field

[0001] The invention relates to the field of electric wires and cables, and in particular to an angle-mounted cable for indoor open-wire laying. Background Art

[0002] In the indoor power supply network of industrial and civil buildings, round copper-plastic wires or aluminum-plastic wires are mainly used for power transmission. The laying methods of such wires are mainly concealed installation in pipes and open installation along walls. The concealed installation method of pipes requires a lot of maintenance work in the event of a failure, and even the wall needs to be chiseled and the building needs to be damaged.

[0003] In order to solve the technical problems of difficult maintenance and complicated installation process in the above-mentioned concealed wiring laying method, the prior art proposes installation wires suitable for indoor open wiring laying, which can be referred to in the Chinese patent literature, namely, the technology named "a convenient indoor installation wire", publication number CN205943558U, and publication date February 8, 2017, and the technology named "a convenient indoor installation wire", publication number CN206331811U, and publication date July 14, 2017. In such technology, a fan-shaped plastic sheath is wrapped around the outside of the conductive unit, and circular and diamond-shaped expansion holes are designed inside the sheath, and the outside is covered with a strong double-sided adhesive tape. Although this type of technology can achieve rapid installation and maintenance of wires in an open-wire manner, since most indoor structural angles (such as wall corners, ground corners, and top angles) are right-angle structures, the fan-shaped plastic sheath cannot completely match the indoor right-angle structure during installation, resulting in a failure to form a surface contact installation, poor stability, and the curved edges are exposed, resulting in poor visual effects. Summary of the invention

[0004] The technical purpose of the present invention is to provide an angle-mounted cable for indoor open-line laying, which can form surface-contact laying and installation, has stable installation and visual appeal, in view of the deficiencies of the above-mentioned prior art.

[0005] The technical solution adopted by the present invention is as follows: An angle-mounted cable for indoor open-wire installation, having at least one insulating core; The outer part of the insulating wire core is extruded with a sheath layer having a right-angled triangle cross section; In the indoor open-line laying operation, the cable is connected to the indoor angle part with two right-angled sides, and the two right-angled sides of the sheath layer are connected with double-sided tape.

[0006] The cross-section of the sheath layer in the above technical measures is a right-angled triangle, which can better fit the indoor angle, enhancing the installation stability while taking into account the aesthetics; the double-sided tape is used to achieve surface contact installation between the cable and the indoor angle structure, which is easy to install, convenient for fault repair, and low in construction and maintenance costs.

[0007] Furthermore, the cross section of the sheath layer is an isosceles right triangle structure; The arrangement position of the insulated wire core in the sheath layer is aligned with the right angle of the sheath layer as the center.

[0008] In the above technical measures, the cross-section of the sheath layer is an isosceles right triangle structure, which can better fit the angle of the indoor wall and improve the aesthetics; the arrangement position of the insulated wire core in the sheath layer is aligned with the right angle of the sheath layer, which is easy to install and helps to enhance stability.

[0009] Furthermore, a pre-expansion hole is respectively provided in the sheath layer on both sides of the insulating core.

[0010] The above technical measures provide a pre-expansion hole, which can cause the pre-expansion hole to deform when the cable is pressed against the angle of the wall. The rebound force generated by the deformation acts on the wall, thereby making the cable more firmly bonded to the wall.

[0011] Furthermore, the two pre-expansion holes in the sheath layer are arranged in a left-right symmetrical structure along the insulating core.

[0012] In the above technical measures, the two pre-expansion holes are arranged in a left-right symmetrical structure along the insulating core, which can generate equal rebound force when under pressure and act evenly on the wall, so that the cable is more firmly bonded to the wall.

[0013] Furthermore, the pre-expansion hole is a circular structure or a diamond structure.

[0014] In the above technical measures, the pre-expansion hole is a circular structure or a diamond structure, which can be deformed when under pressure and can reduce local stress concentration when under pressure, thereby improving the durability of the cable.

[0015] Furthermore, the insulating cores are multiple and arranged in parallel, and the insulating cores are closely arranged along the high line direction at the oblique side of the sheath layer; Each insulated wire core is composed of a conductor and an insulating layer wrapped around it.

[0016] In the above technical measures, the insulated cores are arranged in parallel and closely along the high-line direction of the oblique side of the sheath layer, making the structure compact and helping to reduce the volume of the cable; by providing an insulating layer wrapped around the outside of the conductor, current leakage and short circuit can be effectively prevented.

[0017] Furthermore, the conductor of the insulated core is a single-wire structure or a multi-wire concentric twisted structure; The conductor of the insulated wire core is a copper wire or an aluminum wire.

[0018] The above technical measures use copper wire or aluminum wire as the conductor, which is conducive to reducing costs while ensuring the flexibility and electrical conductivity of the conductor.

[0019] Furthermore, the sheath layer is an extruded structure of polyvinyl chloride material or polyethylene material.

[0020] In the above technical measures, the sheath layer is an extruded structure of polyvinyl chloride material or polyethylene material, which is beneficial to protect the cable from being affected by environmental factors, improve the durability of the cable, and reduce costs.

[0021] One or more technical solutions provided by the present invention have at least the following technical effects or advantages: The cross-section of the sheath layer in the present invention is a right-angled triangle, which can better fit the indoor angle, enhancing the installation stability while taking into account the aesthetics; the cable is installed in surface contact with the indoor angle structure through double-sided tape, which is convenient for installation, easy for fault repair, and low in construction and maintenance costs.
