[0002] Communication cables are used to transmit telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. They are made of one or more mutually insulated wires twisted together. Compared with overhead wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less impact from natural conditions and external interference.

[0003] High-frequency high-speed cables are used to quickly transmit high-frequency signals. Since cables have distributed capacitance and distributed inductance, they can filter and attenuate high-frequency signals. Therefore, for the transmission of high-frequency signals, cables with small distributed capacitance and distributed inductance are required.

[0004] After the high-frequency high-speed cable intermediate joint is installed on site, during operation, it is inevitable that the insulation will be damaged due to external factors such as moisture intrusion and mechanical stress, causing the cable intermediate joint to break down and explode. Due to the particularity of high-frequency high-speed cables, any problem at the joint will affect the normal use of high-frequency high-speed cables. Utility Model Content

[0020] The utility model provides a protective structure for high-frequency and high-speed digital communication cables, comprising an upper shell 1 and a lower shell 2, wherein mounting grooves 3 are provided at the lower ends of both sides of the upper shell 1, through grooves 4 are provided outwardly on the side walls of the mounting grooves 3, the through grooves 4 are communicated with the outside, and fixing rods 5 are slidably connected in the through grooves 4, and fixing blocks 6 are fixedly connected at the upper ends of both sides of the lower shell 2, the fixing blocks 6 are slidably connected to the mounting grooves 3, and fixing grooves 7 matching the through grooves 4 are provided on the fixing blocks 6, the fixing rods 5 are slidably connected to the fixing grooves 7, and buffer devices are provided in both the upper shell 1 and the lower shell 2. After the high-frequency, high-speed digital communication cable is connected, the upper shell 1 and the lower shell 2 are respectively placed above and below the connection of the cable, and then the fixing rod 5 on the upper shell 1 is pulled outward so that the inner end of the fixing rod 5 leaves the installation groove 3, and then the upper shell 1 is moved downward so that the fixing block 6 can enter the installation groove 3. When the fixing groove 7 on the fixing block 6 reaches a position aligned with the through groove 4, the fixing rod 5 is pushed so that the fixing rod 5 passes through the fixing groove 7, thereby completing the assembly of the upper shell 1 and the lower shell 2, thereby protecting the connection of the high-frequency, high-speed digital communication cable, and preventing the joint from being damaged by moisture intrusion or external forces such as mechanical stress, thereby playing a protective role. At this time, the buffer device can reduce and buffer the vibration caused by external forces such as mechanical stress such as impact while fixing the cable.

[0021] In order to prevent the fixing rod 5 from falling off, as a preferred embodiment, a pull plate 8 is fixedly connected to the outer end of the fixing rod 5, and a first spring 9 is arranged between the pull plate 8 and the upper shell 1, and the two ends of the first spring 9 are respectively fixedly connected to the upper shell 1 and the pull plate 8. The first spring 9 can limit the fixing rod 5 to prevent it from falling off.

A second spring 16 is sleeved on the outer side of the sliding rod 14, and the two ends of the second spring 16 are respectively fixedly connected to the mounting seat 12 and the pressing plate 15. When subjected to mechanical stress, the sliding rod 14 will slide into the sliding groove 13, thereby squeezing the second spring 16. Under the action of elastic potential energy, the second spring 16 can absorb the impact, thereby playing a buffering role. Preferably, dampers are respectively provided at both ends of the second spring 16.

[0025] As a preferred embodiment, the pressing plate 15 is an arc-shaped plate, and the outer shape of the pressing plate 15 is a minor arc shape.
