Technical Field

[0001] The present invention relates to the field of cable protection components, and specifically to an anti-interference communication cable protection device. Background Art

[0002] An anti-interference communication cable is a cable used to transmit digital signals, consisting of a cable core formed by multiple mutually insulated wires or conductors, and a communication line with a sealed sheath on the outside. Some also have an outer protective layer outside the sheath. The communication cable has a relatively wide transmission bandwidth, a large communication capacity, and is less affected by external interference, but it is not easy to repair. It can transmit telephone, telegraph, data, images, etc.

[0003] In the prior art, there is a phenomenon that the anti-interference communication cable penetrates the wall during construction. Usually, a PVC pipe body is sleeved outside the anti-interference communication cable for protection; and the Chinese invention with the application number CN202011301775.4 proposed an assembled cable wall-penetrating device, and the Chinese invention with the application number CN201911320694.6 proposed a cable wall-penetrating structure and its wall-penetrating construction method; both adopt the form of sleeving a pipe body outside the anti-interference communication cable to achieve the wall-penetrating protection of the anti-interference communication cable.

[0004] However, the wall-penetrating protection pipe body sleeved outside the anti-interference communication cable needs to be cut on-site to meet the usage requirements. In this way, cutting equipment needs to be configured for the wire body to penetrate the wall, and there is a lack of a fixing structure between the protection pipe body sleeved outside the anti-interference communication cable and the wall, there is a hidden danger of the protection pipe body falling off, and there is a lack of a limiting structure between the protection pipe body and the anti-interference communication cable. When the anti-interference communication cable is randomly pulled, it is easy to cause the wiring at the end of the anti-interference communication cable to become loose. Summary of the Invention

[0031] Refer to the attached Figures 5 - 9, on the basis of the first embodiment, the length of the protective pipe body penetrating the wall hole is adjusted. The extension protection member includes an assembly groove 2, an embedding groove 3, a rubber gasket 4 and an assembly plate 5. The outer ring surface of the wall-piercing sleeve 1 is provided with the assembly groove 2. There are multiple assembly grooves 2, and the multiple assembly grooves 2 are arranged and distributed along the outer ring surface of the wall-piercing sleeve 1.

The assembly plate 5 corresponds to the assembly groove 2 one by one, and the assembly plate 5 is slidably connected in the assembly groove 2. The limit clamping assembly includes a side groove 6, a through hole 7, a clamping block 8, a pressing frame 9, a rubber clamping block 10 and a reserved groove 31. The side groove 6 is opened at one end of the assembly plate 5, the through hole 7 is opened on the surface of the side groove 6, the clamping block 8 is movably inserted into the through hole 7, one end of the clamping block 8 is provided with two symmetrically distributed inclined surfaces, and the other end of the clamping block 8 is provided with a notch. The pressing frame 9 is in a "C"-shaped plate structure, and the pressing frame 9 is movably inserted into the reserved groove 31. The reserved groove 31 is opened on the surface of the side groove 6, and the reserved groove 31 communicates with the through hole 7. A rubber clamping block 10 is fixed between the pressing frame 9 and the reserved groove 31. The surface of the rubber clamping block 10 is provided with a force-relieving port.

The limit frame 19 has a square ring plate structure. The top support screws 20 are screwed on the two parallel inner walls of the limit frame 19. The wire bundling strips 21 are fixed on the top surface of the bottom plate of the limit frame 19. Multiple wire bundling grooves 22 are formed on the top surface of the wire bundling strips 21.

After both groups of top support screws 20 abut against the inner wall of the wall hole, the installation and fixation of the protective pipe body are realized. After the two ends of the anti-interference communication cable are connected, rotate the adjusting screw 26 to squeeze the wire bundling strips 21 downward to clamp the anti-interference communication cable, so as to prevent the anti-interference communication cable from moving inside the protective pipe body when being pulled, thereby avoiding the loosening of the connection of the anti-interference communication cable at the other end when the anti-interference communication cable is pulled out from one end.
