Description

Technical Field

[0001] This utility model relates to the field of shielded cable technology, and in particular to a composite multi-core shielded cable. Background Technology

[0002] Shielded cables, also known as control cables, are characterized by using a metal mesh braid to wrap the signal lines, forming a shield. This shield is usually made of red copper or tin-plated copper, and its purpose is to reduce the influence of external electromagnetic fields on power or communication lines and prevent the lines from radiating electromagnetic energy.

[0003] The presence of a shielding layer can effectively prevent the intrusion of external interference signals, thereby improving the stability and accuracy of signal transmission. In the existing technology, shielded cables are easily subjected to external pressure during use. After being squeezed, the shielding layer is easily deformed and it is difficult to restore its original shape. In severe cases, the shielding layer may be damaged, affecting the stability and accuracy of signal transmission and making it impractical. Therefore, it is necessary to redesign a composite multi-core shielded cable to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a composite multi-core shielded cable.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A composite multi-core shielded cable includes a cable body, a partition sleeve slidably installed inside the cable body, a toothed plate fixedly installed on the outer wall of the partition sleeve through an installation groove, two connecting plates fixedly installed on the outer wall of the cable body through a connecting mechanism, a gear meshing with the toothed plate fixedly installed between the two connecting plates through a rotating mechanism, a rotating opening cooperating with the gear on the outer wall of the cable body, two first connecting frames fixedly installed on the outer wall of the cable body through a fixing mechanism, a second connecting frame rotatably connected inside each of the two first connecting frames through a connecting mechanism, a buffer block fixedly installed on the bottom wall of each of the two second connecting frames, a sliding rod and a limiting rod slidably installed through the outer walls of the two buffer blocks, buffer frames fixedly installed at both ends of the sliding rod and the limiting rod, and the outer walls of the two buffer blocks connected to the inner walls of the buffer frames through a buffer mechanism.

[0007] Preferably, the connecting mechanism includes a connecting sleeve fixedly installed on the outer wall of the cable body, and both connecting plates are fixedly installed on the outer wall of the connecting sleeve.

[0008] Preferably, the rotating mechanism includes a rotating shaft rotatably mounted between two connecting plates, a gear fixedly mounted on the outer wall of the rotating shaft, and a nut fixedly mounted on the outer wall of the rotating shaft.

[0009] Preferably, the fixing mechanism includes a fixing sleeve fixedly installed on the outer wall of the cable body, and both first connecting frames are fixedly installed on the outer wall of the fixing sleeve.

[0010] Preferably, the connecting mechanism includes a connecting plate rotatably installed inside the first connecting frame, and the end of the connecting plate is rotatably connected to the interior of the intersecting second connecting frame.

[0011] Preferably, the buffer mechanism includes a buffer spring installed on the outer wall of the slide bar, and the two ends of the buffer spring are elastically connected to the outer wall of the buffer block and the inner wall of the buffer frame, respectively.

[0012] Preferably, the outer wall of the separator sleeve is provided with multiple connecting grooves, and multiple connecting shafts are fixedly installed inside each connecting groove. Rollers are rotatably installed on the outer wall of each connecting shaft.

[0013] Preferably, a fixing plate is fixedly installed on the bottom wall of the buffer frame, and multiple fixing holes are provided on the upper surface of the fixing plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up components such as gears, toothed plates, and separator sleeves, the gears can rotate and mesh with the toothed plates, causing the separator sleeve to be subjected to force and penetrate deep into the cable body through the cooperation of multiple rollers. This enables convenient installation of the separator sleeve. The installation of the separator sleeve can prevent the inner wall of the cable body and the outer wall of multiple conductors from being squeezed and deformed when the cable body is fixed, and can also prevent the shielding layer from being squeezed and damaged, thereby preventing the stability and accuracy of signal transmission from being affected.

[0016] 2. By setting up components such as the first connecting frame, connecting plate, second connecting frame and buffer spring, the fixed sleeve transmits the force generated by vibration to the second connecting frame through the cooperation of the first connecting frame and the connecting plate. The force on the second connecting frame can drive the buffer block to slide on the outer wall of the slide rod through the cooperation of the limiting rod and squeeze the buffer spring. The elasticity of the buffer spring can absorb and buffer the force, thereby increasing the stability of the cable body during use. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A composite multi-core shielded cable includes a cable body 1, a partition sleeve 2 slidably installed inside the cable body 1, a toothed plate 3 fixedly installed on the outer wall of the partition sleeve 2 through an installation groove, two connecting plates 5 fixedly installed on the outer wall of the cable body 1 through a connecting mechanism, the connecting mechanism including a connecting sleeve 4 fixedly installed on the outer wall of the cable body 1, both connecting plates 5 fixedly installed on the outer wall of the connecting sleeve 4, a gear 7 meshing with the toothed plate 3 fixedly installed between the two connecting plates 5 through a rotating mechanism, the rotating mechanism including a rotating shaft 6 rotatably installed between the two connecting plates 5, the gear 7 fixedly installed on the outer wall of the rotating shaft 6, a nut 8 fixedly installed on the outer wall of the rotating shaft 6, multiple connecting grooves are opened on the outer wall of the partition sleeve 2, multiple connecting shafts 9 are fixedly installed inside each connecting groove, and a roller 10 is rotatably installed on the outer wall of each connecting shaft 9.

[0027] The outer wall of the cable body 1 has a rotating opening that engages with the gear 7. Two first connecting frames 12 are fixedly installed on the outer wall of the cable body 1 by a fixing mechanism. The fixing mechanism includes a fixing sleeve 11 fixedly installed on the outer wall of the cable body 1. Both first connecting frames 12 are fixedly installed on the outer wall of the fixing sleeve 11. A second connecting frame 14 is rotatably connected inside each of the two first connecting frames 12 by a connecting mechanism. The connecting mechanism includes a connecting plate 13 rotatably installed inside the first connecting frame 12. The end of the connecting plate 13 is rotatably connected to the interior of the intersecting second connecting frame 14.

[0028] Both second connecting frames 14 have buffer blocks 15 fixedly installed on their bottom walls. The outer walls of the two buffer blocks 15 are slidably connected by a slide rod 16 and a limiting rod 17. Both ends of the slide rod 16 and the limiting rod 17 are fixedly installed with a buffer frame 18. The limiting rod 17 can restrict the two buffer blocks 15, so that the two buffer blocks 15 can only move axially along the outer wall of the slide rod 16. The outer walls of the two buffer blocks 15 are connected to the inner wall of the buffer frame 18 through a buffer mechanism. The buffer mechanism includes a buffer spring 19 installed on the outer wall of the slide rod 16. The two ends of the buffer spring 19 are elastically connected to the outer wall of the buffer block 15 and the inner wall of the buffer frame 18, respectively. A fixing plate 20 is fixedly installed on the bottom wall of the buffer frame 18. The upper surface of the fixing plate 20 has multiple fixing holes.

[0029] In use, the separator sleeve 2 is first slidably installed inside the cable body 1 so that the toothed plate 3 and the gear 7 mesh together, and then respectively fitted onto the outer wall of multiple wires. Then, the nut 8 can be turned to drive the rotating shaft 6 to rotate. The rotating shaft 6 can drive the gear 7 to rotate. When the gear 7 rotates and meshes with the toothed plate 3, the separator sleeve 2 can be subjected to force and penetrate into the cable body 1 through the cooperation of multiple rollers 10. Thus, the separator sleeve 2 can be conveniently installed. By installing the separator sleeve 2, the inner wall of the cable body 1 and the outer wall of multiple wires can be prevented from being squeezed and deformed when fixed, and the shielding layer can also be prevented from being squeezed and damaged, thereby preventing the stability and accuracy of signal transmission from being affected.

[0030] When the cable body 1 is installed and fixed, the fixing plate 20 can be fixedly installed on the equipment through the fixing hole and the fixing bolt. When the equipment vibrates due to external force, the fixing sleeve 11 can transfer the force generated by the vibration to the second connecting frame 14 through the cooperation of the first connecting frame 12 and the connecting plate 13. At this time, the second connecting frame 14 is subjected to force and can drive the buffer block 15 to slide on the outer wall of the slide rod 16 through the cooperation of the limiting rod 17. During the sliding process, the buffer spring 19 is squeezed. Thus, the buffer spring 19 can absorb the force by deforming under force and buffer the force by releasing elastic potential energy. This avoids affecting the stability of the cable body 1 during use and prevents the loosening of the connection of the cable body 1. In the process of the buffer spring 19 releasing elastic potential energy, the buffer block 15 will generate friction when sliding on the outer wall of the slide rod 16 and the limiting rod 17. This friction can buffer the elastic potential energy released by the buffer spring 19. Without affecting the vibration reduction, it can also avoid resonance and reciprocating vibration.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
