[0002] Cables are usually rope-like cables made up 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 wire. The entire outside is covered with a highly insulating protective layer.
[0003] Currently, an anti-stretching layer is provided on the outer layer of the cable to improve its tensile resistance. However, the anti-stretching layer can only improve the tensile resistance of the outer layer of the cable. However, the interior of the cable does not have good tensile resistance, resulting in poor protection of the conductive core inside the cable. When the cable is pulled by external force, the conductive core may be deformed and broken. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that the cable in the prior art does not have good tensile resistance, resulting in poor protection of the conductive core inside the cable, and the conductive core may be deformed and broken when the cable is pulled by external force, and to propose a tensile-resistant cable.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A stretch-resistant cable comprises an insulating protective layer and also includes: an outer stretch-resistant layer fixedly connected to the inner surface of the insulating protective layer; wherein the inner surface of the outer stretch-resistant layer is fixedly connected to an outer reinforcement layer; a first stretch-resistant portion is arranged inside the outer reinforcement layer, and the first stretch-resistant portion is used to support the inside of the outer reinforcement layer; a plurality of copper core conductors are all connected to the inside of the outer reinforcement layer through a second stretch-resistant portion, and the second stretch-resistant portion is used to support the copper core conductors; and a filler is arranged inside the outer reinforcement layer.
[0007] In order to improve the tensile resistance of the cable, preferably, the first tensile resistance part comprises a tensile frame fixedly connected to the inside of the outer reinforcement layer, and a tensile core is fixedly connected to the tensile frame.
[0008] In order to further improve the tensile resistance of the cable, the second tensile resistance part further includes an inner reinforcement layer sleeved on the copper core conductor, and the inner tensile resistance layer is fixedly connected to the outer wall of the inner reinforcement layer; both sides of the outer surface of the inner tensile resistance layer are fixedly connected to anti-tensile plates, and the sides of the two anti-tensile plates away from the inner anti-tensile layer are respectively fixedly connected to the inner wall of the outer reinforcement layer and the surface of the tensile frame.
[0009] In order to make the strength of the tensile frame higher, further, the number of the tensile cores is multiple, and the multiple tensile cores are arranged on the tensile frame at equal intervals.
[0010] In order to ensure the strength of the cable, preferably, the material of the outer tensile resistance layer is steel wire, and the material of the outer reinforcement layer is cross-linked polyethylene.
[0011] In order to further ensure the strength of the cable, further, the material of the inner reinforcement layer is glass fiber, and the material of the inner tensile resistance layer is polyamide fiber.
[0012] Compared with the prior art, the utility model provides a stretch-resistant cable having the following
[0013] Beneficial effects:
[0014] 1. The stretch-resistant cable can improve the stretch resistance of the outer layer of the cable by arranging an outer stretch-resistant layer and an outer reinforcement layer. At the same time, the stretch resistance of the inner part of the cable can be improved by arranging an anti-tensile frame and an anti-tensile core, and provide support for the outer reinforcement layer, while protecting the copper core conductor. When the cable is pulled by external force, the tensile force on the copper core conductor can be shared by the anti-tensile frame and the anti-tensile core.
[0015] 2. The stretch-resistant cable can further improve the tensile resistance of the cable by providing an inner reinforcement layer, an inner tensile-resistant layer and an anti-tensile plate, and protect the copper core conductor. When the cable is pulled by an external force, the tensile force on the copper core conductor can be further shared;
[0016] Therefore, by connecting and cooperating the outer anti-stretching layer, the outer reinforcement layer, the tensile frame, the inner anti-stretching layer and the anti-stretching plate and other structures to each other, an anti-stretching frame structure can be formed, thereby achieving the enhancement of the tensile resistance inside and outside the cable, greatly improving the protection effect of the copper core conductor inside the cable. When the cable is pulled by external force, the tensile force on the copper core conductor can be shared by forming an anti-stretching frame structure, thereby preventing the copper core conductor inside the cable from being torn apart due to external force.
[0017] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model solves the problem that the cable inside the existing technology does not have good tensile strength, resulting in poor protection of the conductive core inside the cable, and the conductive core may be deformed and broken when the cable is pulled by external force.
