The satisfaction rate of product varieties and the domestic market share both exceed 90%. With the rapid development of the Chinese wire and cable industry, the number of new enterprises is increasing continuously, and the overall technical level of the industry has been greatly improved. The sustained and rapid growth of the Chinese economy provides a huge market space for cable products.

[0003] The Chinese patent document with the publication number CN217157769U discloses a comprehensive cable with corrosion resistance. The device has a polyester filler inside the communication cable, which has high strength and elastic recovery ability. It is firm, durable, wrinkle-resistant and non-ironing, achieving the effect of preventing the cable body from being squeezed.

The outer side is provided with an outer protective layer, a corrugated steel strip and an inner protective layer with multiple protections, which are resistant to compression, weathering and preventing rats from biting, greatly extending the service life of the data communication cable;

[0004] However, during the use of the outer protective layer of the device, it is inevitable that it accidentally falls to the ground and comes into contact with the ground, resulting in the problem of surface damage to the outer protective layer. Furthermore, it cannot be guaranteed whether the outer protective layer can continuously play a protective role. Further, it is necessary to repair or replace the outer protective layer according to the situation, causing a certain waste of resources. Therefore, it is necessary to improve the outer protective layer. Summary of the Utility Model

Thus, the protection device protects the wrapping skin, preventing it from being damaged by direct contact with the ground. At the same time, it can also reduce the vibration force on the cable and ensure that the cable always operates in a stable state.

[0027] In this embodiment, the fixed film layers 62 are symmetrically arranged at the left and right ends of the housing one 61. The elastic filler 63 and the movable block 65 are vertically arranged inside the housing one 61. There are two groups of the limiting grooves 64 and the limiting blocks 66, and the two groups of the limiting grooves 64 and the limiting blocks 66 are respectively arranged at both ends of the bottom of the movable block 65, ensuring that the limiting grooves 64 and the limiting blocks 66 arranged on both sides of the movable block 65 can cooperate with each other to limit the movable block 65.

The protective layer 673 is made of wear-resistant linen and has the characteristic of wear resistance.

[0030] Refer to Figures 1 - 5, during use, both ends of the signal line 1 are respectively connected to the wiring ports of the power supply device and the receiving device, so that the signal line 1 can transmit power signals.
