The outer wall of the second positioning rubber tube 11 is provided with outer positioning protrusions 22 at equal intervals. The outer positioning protrusions 22 are connected to the armored protective tube 8.

[0023] In the specific implementation process, it is worth noting that, through the cooperation between the metal cable tray 1 and the first communication cable 2, the first communication cable 2, which is the main communication cable in the solar photovoltaic power generation transmission system, is arranged inside the metal cable tray 1 to provide protection for the first communication cable 2. Through the cooperation between the metal cable tray 1, the first communication cable 2, the fixing hole 3, the fixing base plate 4, and the fixing seat 5, the fixing hole 3 is opened at the top of the metal cable tray 1 near the connecting equipment, and the fixing base plate 4 and the fixing seat 5 are installed above the fixing hole 3. The first communication cable 2 is then passed through the fixing hole 3 and the fixing seat 5 to connect with the communication cable of the connecting equipment. Through the connecting seat 6, the slot 7, and the armored protective tube 8, and the first communication cable 2 is connected to the connecting equipment. The two communication cables 9 are fitted together by inserting the armored sheath 8 and connector 6 onto the outside of the second communication cable 9.

The inner positioning protrusion 12 abuts against the second communication cable 9, and the outer positioning protrusion 22 abuts against the armored protective tube 8, ensuring the second communication cable 9 remains stable inside the armored protective tube 8 and preventing shaking during installation. This is achieved through the cooperation between the metal cable tray 1, the first communication cable 2, the fixing hole 3, the fixing base plate 4, the fixing seat 5, the connecting seat 6, the slot 7, the armored protective tube 8, the second communication cable 9, the first positioning rubber tube 10, the second positioning rubber tube 11, the inner positioning protrusion 12, and the outer positioning protrusion 22.By making an opening in the metal cable tray 1 near the connecting device and installing a fixing base 5, the first communication cable 2 passes through the fixing base 5 and the first positioning rubber tube 10, and connects to the second communication cable 9 inside the armored protective tube 8. Then, the connecting seat 6 at the bottom of the armored protective tube 8 is inserted into the fixing base 5 and fixed in place. The first positioning rubber tube 10 and the second positioning rubber tube 11 respectively secure and position the two communication cables, preventing them from shaking during long-term installation and avoiding interference or damage from the external environment. This provides effective protection for the communication cables, reduces their failure rate, improves the convenience of later maintenance, and lowers maintenance costs.

[0025] In the specific implementation process, it is worth noting that through the cooperation between the fixed seat 5, the connecting seat 6, the first connecting groove 13, the second connecting groove 14 and the sealing ring 15, after the connecting seat 6 is inserted into the top of the fixed seat 5, a double limiting and sealing effect is formed at the first connecting groove 13 and the second connecting groove 14, which ensures the connection stability between the connecting seat 6 and the fixed seat 5, avoids loosening of the connection due to long-term use or external environmental influence, and prevents water seepage or dust from entering at the connection point, ensuring the reliability and stability of the connection structure for long-term use, and further improving the protection effect of the communication cable;

[0026] Furthermore, an extension tube 16 is provided at the bottom of the fixed base plate 4. The extension tube 16 is connected to the fixed hole 3.

The extension tube 16 extends downward from the bottom of the fixing base plate 4 and passes into the inside of the fixing hole 3. After passing through the fixing hole 3, the limiting clip 17 is clamped and limited with the metal cable tray 1. This not only enhances the connection strength between the fixing base plate 4 and the metal cable tray 1, but also avoids wear on the communication cable at the fixing hole 3.

[0030] Furthermore, a rubber pad 21 is fixedly connected to the bottom of the fixed base plate 4, and the rubber pad 21 is connected to the metal cable tray 1.

[0031] In the specific implementation process, it is worth noting that the rubber pad 21 is used to enhance the fit between the fixed base plate 4 and the metal cable tray 1, prevent the fixed base plate 4 from shifting on the metal cable tray 1, and ensure the stability of the fixed base plate 4. In addition, the rubber pad 21 also has a certain shock absorption effect, which can effectively reduce the noise and vibration generated when the fixed base plate 4 and the metal cable tray 1 make hard contact, and further improve the overall stability and service life of the cable positioning device.
