Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, and more specifically, the utility model relates to an anti-tensile dynamic control composite cable. Background Art
[0002] A cable is a wire product used for transmitting electrical energy information and realizing the conversion of electromagnetic energy. It usually consists of a conductor, an insulating layer, and a protective layer, and has a complex structure and a large cross-sectional area. A dynamic control composite cable, also known as a power control composite cable, is a special type of cable mainly used for simultaneously transmitting electrical energy and control signals.
[0003] Although the dynamic control composite cables in the prior art can be used normally, there are still many disadvantages in actual use. For example, when the dynamic control composite cables in the prior art are arranged and constructed, the cables themselves are often dragged, which will stretch the cables. Since the longer the cable, the greater the mass, when the length is relatively long, the relatively large mass may cause the internal structure or even the whole cable to break during dragging. This makes the anti-tensile performance of the dynamic control composite cables in the prior art relatively poor. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an anti-tensile dynamic control composite cable. By providing an anti-tensile protective layer and anti-tensile components, when the utility model is arranged and constructed, if the cable is dragged, the cable is difficult to be stretched, thereby avoiding the situation that when the dragged length of the cable is relatively long, the relatively large mass may cause the internal structure or even the whole cable to break during dragging, making the anti-tensile performance of the utility model relatively good, so as to solve the problems raised in the above-mentioned background art.
[0005] To achieve the above object, the utility model provides the following technical solution: an anti-tensile dynamic control composite cable, including an inner insulating coating layer of the cable, inside which there is a cable wire core. The number of the cable wire cores is set to six. An anti-tensile protective layer is arranged outside the inner insulating coating layer of the cable, and four anti-tensile components are arranged inside the anti-tensile protective layer;
[0006] The anti-tensile component includes an anti-tensile wire, on which a plurality of fixing nodes are arranged.
[0007] In a preferred embodiment, the anti-tensile protective layer is made of polypropylene fiber material, and the anti-tensile wire is made of aluminum wire material.
[0008] In a preferred embodiment, the four anti-tensile components are respectively arranged around the inside of the anti-tensile protective layer.
[0009] In a preferred embodiment, the anti-tensile wire and the fixing node are both arranged inside the anti-tensile protective layer.
[0010] In a preferred embodiment, a wear-resistant protective layer is arranged on the outer side of the anti-tensile protective layer, and the wear-resistant protective layer is made of nitrile rubber material.
[0011] The technical effects and advantages of the present utility model:
[0012] 1. By providing the anti-tensile protective layer and the anti-tensile assembly, when the present utility model is arranged and constructed, if the cable is dragged, the cable is difficult to be stretched, thus avoiding the situation that when the dragging length of the cable is relatively long, the relatively large mass may cause the internal structure or even the whole of the cable to break during dragging, so that the anti-tensile performance of the present utility model is better;
[0013] 2. By providing the wear-resistant protective layer, since the nitrile rubber material has wear resistance, the wear-resistant protective layer made of nitrile rubber material has good wear resistance, which can improve the wear resistance of the outer wall of the composite cable, thereby increasing the service life of the present utility model.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model;
[0019] Such as in the attached Figures 1-3As shown in the figure, the present utility model provides an anti-tensile dynamic control composite cable, including a cable inner insulation coating layer 1. Inside the cable inner insulation coating layer 1, there is a cable wire core 2. The number of the cable wire cores 2 is set to six. Outside the cable inner insulation coating layer 1, there is an anti-tensile protection layer 3. Inside the anti-tensile protection layer 3, there are four anti-tensile components 4;
[0020] The anti-tensile component 4 includes an anti-tensile wire 401, and a plurality of fixing nodes 402 are arranged on the anti-tensile wire 401;
[0021] The anti-tensile protection layer 3 is made of polypropylene fiber material, and the anti-tensile wire 401 is made of aluminum wire material. The anti-tensile wire 401 made of aluminum wire has high strength and is not easy to break;
[0022] The four anti-tensile components 4 are respectively arranged around the inside of the anti-tensile protection layer 3;
[0023] The anti-tensile wire 401 and the fixing nodes 402 are both arranged inside the anti-tensile protection layer 3;
[0024] Outside the anti-tensile protection layer 3, there is a wear-resistant protection layer 5. The wear-resistant protection layer 5 is made of nitrile rubber material. Since the nitrile rubber material has wear resistance, the wear-resistant protection layer 5 made of nitrile rubber material has good wear resistance, which can improve the wear resistance of the outer wall of this composite cable, thereby increasing the service life of the present utility model.
[0025] The specific implementation method is as follows: When using the present utility model, since the polypropylene fiber material has a relatively light weight and good elasticity, the anti-tensile protection layer 3 made of polypropylene fiber material also has a relatively light weight and good elasticity, so it can absorb and disperse the tensile force, thereby protecting the cable itself from being strained and improving the anti-tensile performance of the cable. Then, the four anti-tensile components 4 are arranged inside the anti-tensile protection layer 3. Each fixing node 402 can limit the position of the anti-tensile wire 401 inside the anti-tensile protection layer 3, so that the anti-tensile wire 401 will not have relative displacement inside the anti-tensile protection layer 3. Then, the anti-tensile wire 401 cooperates with the fixing nodes 402 to achieve the effect of tightening the anti-tensile protection layer 3, preventing the overall cable from being stretched, and further preventing the cable from being broken. When the present utility model is being laid and constructed, if the cable is dragged, it is difficult to stretch the cable, thus avoiding the situation that when the dragging length of the cable is relatively long, the relatively large mass may cause the internal structure or even the whole cable to break during dragging, making the anti-tensile performance of the present utility model better.
[0026] The working principle of the present utility model:
[0027] Refer to the attached drawings of the specification Figures 1-3, when using the present utility model, with the anti-tensile protective layer 3 and the anti-tensile component 4 provided, when the present utility model is arranged and constructed, if the cable is dragged, the cable is difficult to be stretched, thus avoiding the situation that when the dragging length of the cable is relatively long, the relatively large mass may cause the internal structure of the cable or even the whole cable to break during dragging, so that the anti-tensile performance of the present utility model is relatively good.
