Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof core-spun wires, and particularly relates to a waterproof core-spun wire. Background Art

[0002] Waterproof cored wire generally refers to a special cable structure designed to maintain stable electrical performance and long service life in a humid, submerged or high humidity environment. The core feature of this type of cored wire is that it has excellent waterproof performance, which can ensure that the internal conductor and insulation material of the wire are not damaged when it comes into contact with moisture or is submerged in water. In the prior art, a protective layer is usually provided on the outside of the insulating core, and an outer sheath layer is provided on the outside of the protective layer. However, in this method, the outer sheath layer is connected to the outside of the protective layer, which is not easy to disassemble. Once a problem occurs inside the cable, it is difficult for technicians to quickly locate the fault point and perform targeted repairs because the outer sheath is tightly fixed to the protective layer and is not easy to disassemble. This may result in the need to cut or replace the entire cable on a larger scale, increasing repair time and cost.

[0003] For example, the utility model with announcement number CN213459111U discloses a new waterproof flexible cable. In the technical solution of this patent, a tape layer and an outer water-blocking tape layer are arranged on the outside of the insulating core, and an outer sheath layer is arranged on the outside of the outer water-blocking tape layer to protect the central conductor inside the core. However, in this method, the outer sheath layer is connected to the outside of the outer water-blocking layer, which makes it inconvenient to disassemble the outer sheath layer. When a conductor or signal transmission element inside the core wire fails, it is difficult to perform local repair or replacement because the outer sheath layer and the outer water-blocking layer are inconvenient to disassemble. It may be necessary to replace the entire cable, increasing maintenance costs and waste of resources. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a waterproof core-spun cable, which not only can conveniently replace the cable body by setting a protective layer, but also can easily remove the protective jacket through the fixed assembly when a fault occurs inside the core-spun cable, and directly inspect, repair or replace the cable body without replacing the entire cable, thereby greatly improving maintenance efficiency and reducing maintenance costs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a waterproof core-spun wire, including a cable body, the outer surface of the cable body is covered with a protective jacket, a fixing component is arranged between the protective jacket and the cable body, and the interior of the cable body is provided with an insulating core and a protective layer.

[0006] As a further improvement of the utility model, the fixing component includes a groove opened at the end of the cable body, a spring sheet is fixedly arranged on the left side wall of the groove, a sliding rod is slidably connected to the right side of the groove, a rotating rod is rotatably arranged inside the groove, a fixing plate is connected to the rotating rod, an arc-shaped protrusion matching the sliding rod is arranged at the left end of the fixing plate, a fixing plate is arranged through the upper side wall of the groove on the right side, a through hole matching the fixing plate is opened on the upper side wall of the groove, and a sliding groove matching the fixing plate is arranged at the end of the protective jacket.

[0007] As a further improvement of the utility model, there are three insulating cores, a conductor is arranged inside the insulating core, an insulating layer is arranged outside the conductor, a waterproof layer is arranged outside the insulating layer, and an inner water-blocking tape layer is arranged outside the waterproof layer.

[0008] As a further improvement of the utility model, the protective layer includes a tape layer arranged on the outside of the insulating core, and an outer water-blocking tape layer is sleeved on the outer side of the tape layer.

[0009] As a further improvement of the utility model, a filling layer is provided between the insulating wire core and the tape layer.

[0010] As a further improvement of the utility model, the inner water-blocking tape layer and the outer water-blocking tape layer are both longitudinally wrapped aluminum-plastic composite tape layers.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Firstly, by setting a fixing component, when the protective jacket needs to be separated from the cable body, the slide rod is pushed to the left, and the end of the slide rod contacts the arc-shaped protrusion on the left side of the fixing plate. The left end of the fixing plate moves upward under the action of the spring plate, thereby causing the fixing plate to rotate, and the fixing plate at the right end of the fixing plate moves downward and disengages from the slide groove at the end of the protective jacket to complete the separation. When a fault occurs inside the cored wire or some components need to be replaced, the protective jacket can be easily disassembled, and the cable body can be directly inspected, repaired or replaced without replacing the entire cable, which greatly improves maintenance efficiency and reduces maintenance costs.

[0013] Secondly, when the protective jacket needs to be fixed to the cable body, pull the slide rod to the right, the end of the slide rod disengages from the arc-shaped protrusion on the left side of the fixed plate, and the left end of the fixed plate moves downward under the action of the spring sheet, thereby causing the fixed plate to rotate, and the fixing plate at the right end of the fixing plate moves upward and slides into the slide groove at the end of the protective jacket, thereby fixing the cable body and the protective jacket.

[0014] Thirdly, an insulating layer is provided on the outside of the conductor. The insulating layer can not only prevent the large current flowing through the cable body from affecting the operation of other equipment components, but also protect the conductor, thus eliminating hidden dangers for workers to a certain extent.

[0015] Fourthly, the inner water-blocking tape layer and the outer water-blocking tape layer are both longitudinally wrapped aluminum-plastic composite tape layers, which are double-layer water-blocking and waterproof, and have better waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS
