TECHNICAL FIELD

[0001] The application relates to the technical field of composite cables, in particular to an anti-interference composite cable. BACKGROUND

[0002] A composite cable is a new type of cable integrating multiple functions or materials, and through structural design optimization, the performance of power transmission, signal communication, mechanical protection and the like is synergistically improved. In order to improve the stability of signal transmission, a shielding layer is usually arranged in the composite cable to resist interference. For example, the anti-interference composite cable disclosed in the announcement No. CN209729564U aims to solve the problem that the power line in the cable easily causes interference to the signal line. The technical solution is as follows: the anti-interference composite cable comprises a power cable, a signal cable and a connecting piece connecting the power cable and the signal cable. The power cable comprises a power line, a current insulation layer wrapped outside the power line, a protection layer wrapped outside the current insulation layer and an outer skin layer wrapped outside the protection layer. The signal cable comprises a signal line, an isolation layer wrapped outside the signal line and an outer skin layer wrapped outside the isolation layer. The power line and the signal line are arranged separately to increase the distance between the power line and the signal line, and the multi-layer isolation layer reduces interference. For example, the compact anti-interference composite cable disclosed in the announcement No. CN215496047U comprises, from inside to outside, a center cable, a first tightening layer, a second tightening layer, a signal strengthening layer, a third tightening layer, a wear-resistant layer and an outer sheath. The center conductor comprises, from inside to outside, a center anti-tension wire core, an outer ring conductor, a water-blocking layer and an outer ring conductor insulation layer. The signal strengthening layer comprises a signal strengthening conductor, a signal strengthening conductor insulation layer and an outer ring anti-tension wire core. The anti-interference composite cable reduces interference between the cables and ensures transmission of communication signals. The overall softness is excellent, the installation and laying cost is reduced, and the enterprise and social benefits are taken into account. However, the above-mentioned anti-interference composite cable still has the following disadvantages in actual use: 1. In the use process of the traditional composite cable, the impact force directly acts on the outer layer of the cable, although it has a certain buffering effect, but it is easy to cause breakage on the outer side of the cable and affect the use, so there is a lack of a structure that reduces damage by deformation when impacted; 2.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0018] Please refer to Figures 1-11 The application provides the following technical solutions: Embodiment 1: In order to solve the problems existing in the prior art, therefore, the embodiment solves the problems by the following technical scheme, an anti-interference composite cable, comprising a cable body 1, the cable body 1 is clamped and installed on the support seat 2, and the support seat 2 is provided with a limiting groove 3 matched with the cable body 1; further comprising: the cable body 1 is composed of an outer sheath 4, a shielding layer 5, an inner sheath 6 and a cable core 7, and the cable core 7, the inner sheath 6, the shielding layer 5 and the outer sheath 4 are arranged in sequence from inside to outside; the outer surface of the cable body 1 is provided with a fixed groove 8, the inner side of the fixed groove 8 is provided with a buffer assembly, and the buffer assembly is used to improve the overall anti-buffering performance of the cable body 1; a limiting assembly is arranged in the inside of the support seat 2, and the limiting assembly is used for limiting between the cable body 1 and the support seat 2.

[0019] The existing composite cable is impacted during use, and the impact force directly acts on the outer layer of the cable. Although it has a certain buffering effect, it is easy to cause rupture on the outside of the cable and affect use, so there is a lack of structure for reducing damage by deformation when impacted, such as Figures 1-5 As shown, the opening of the fixed groove 8 is plugged by a protective sheet 9, and the protective sheet 9 and the fixed groove 8 are made of the same material. The buffer assembly includes a liquid storage bag 10 fixed to the inner side of the fixed groove 8, and the inside of the liquid storage bag 10 stores a colored flame retardant. The liquid storage bag 10 is arranged at equal intervals in the horizontal direction. The buffer assembly further includes a fixed plate 11 fixed to the inner side of the fixed groove 8, and the fixed groove 8 is arranged at equal angles on the outer sheath 4.

When the cable body 1 is impacted by external force, the position of the liquid storage bag 10 is impacted, and has a certain buffering effect. When the outer sheath 4 of the cable body 1 is cracked by impact, the colored flame-retardant liquid in the liquid storage bag 10 can flow out, so that the damaged position can be more directly observed and repaired, as Figure 3As shown, the protective sheet 9 at the position of the liquid storage bag 10 is provided with through holes at equal intervals, when the liquid storage bag 10 is broken by impact and the protective sheet 9 is not broken, the colored flame retardant can flow out from the through holes, thus also playing a marking role, and the through holes can also play a heat dissipation effect after the cable body 1 is extruded, when the cable body 1 encounters a fire, the flame burns the position of the liquid storage bag 10, and the flowing colored flame retardant liquid can play a flame retardant effect, and when the external impact hits the position of the movable plate 13, one end of the movable plate 13 can rotate with the protective sheet 9, and the other end can rotate with the connecting block 12 made of rubber, thereby driving the protective sheet 9 to deform, reducing the impact force on the outer sheath 4, and driving the supporting plate 14 to rotate through the connecting piece 15, when the cable body 1 is not impacted, the movable plate 13 can be quickly driven to return to the initial position through the connecting piece 15 and the connecting block 12 made of rubber, and the movable plate 13, the connecting block 12, the fixed plate 11, the supporting plate 14 and the connecting piece 15 can play a supporting role, supporting the inner side of the fixed groove 8 and ensuring the stability of the cable body 1 as a whole.

[0020] In the laying of the cable, the placement and limiting between adjacent cables are not convenient enough, and the cable needs to be connected with a support structure, and then the support structure needs to be connected with the laying position, which is relatively cumbersome to operate.
