It is also a type of radio station, referring to a radio transceiver station that transmits and receives information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area. The construction of mobile base stations is an important part of the investment of mobile communication operators. The construction of mobile base stations generally revolves around factors such as coverage, call quality, investment efficiency, construction difficulty, and ease of maintenance. As mobile communication network services develop towards data-driven and packet-based directions, the development trend of mobile base stations will inevitably be broadband, large-coverage construction, and IP-based. As an important component of mobile base stations for transmitting current and signals, cables can cause significant damage to connected electronic equipment if struck by lightning.

[0003] The existing copper conductor structure for mobile base station lightning protection cables has poor stability in cable connections, making them prone to breakage at the connection point due to external forces. Furthermore, the existing copper conductor structure for mobile base station lightning protection cables provides poor protection for the cables, resulting in a short service life. The invention provides a copper conductor structure for mobile base station lightning protection cables that solves the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1 to 3This utility model provides a technical solution: a copper conductor structure for a mobile base station lightning protection cable, including a cable body 1, a first protective shell 2, and a second protective shell 3. The end of the first protective shell 2 abuts against the end of the second protective shell 3. A first connector 4 and a second connector 5 are both located inside the first protective shell 2 and the second protective shell 3. The first protective shell 2 and the second protective shell 3 are both sleeved on the outside of the cable body 1. The inside of the first protective shell 2 is provided with a T-shaped groove with the vertical direction as the depth direction and the horizontal direction as the length direction. The end of the T-shaped slider 12 is located inside the T-shaped groove and can slide along the length direction of the T-shaped groove. One side of the second protective shell 3 is provided with a limiting groove with the horizontal direction as the depth direction. The end of the limiting block 10 away from the limiting spring 9 is inserted into the limiting groove. One end of the cable body 1 is provided with a first connector 4. The other end of the cable body 1 is provided with a second connector 5. A stop block 6 is installed on the outer surface of the cable body 1. The position of the stop block 6 corresponds to the position of the first protective shell 2 and the second protective shell 3 respectively. The stop block 6 is located inside the first protective shell 2 and the second protective shell 3. An internal threaded ring 7 is installed on the inner surface of the first protective shell 2. The internal threaded ring 7 and the external threaded ring 8 are threadedly connected. The first connector 4 and the second connector 5 are mated. An external threaded ring 8 is installed on the inner wall of the second protective shell 3. A limit spring 9 is installed inside the first protective shell 2.

The end of the push block 11 away from the limit block 10 is located outside the first protective shell 2. A T-shaped slider 12 is installed at the bottom of the limit block 10.

[0027] In use, when connecting the cable bodies 1, the first connector 4 and the second connector 5 are mated together. Then, holding the first protective shell 2, push the push block 11, causing the push block 11 to move the limiting block 10 and the T-shaped slider 12. This causes the limiting spring 9 to contract under force, and the T-shaped slider 12 to slide along the length of the T-shaped groove. The end of the limiting block 10 retracts into the interior of the first protective shell 2. Rotate the second protective shell 3 to make the internal thread ring 7 and the external thread ring 8 threadedly connected. When the end of the first protective shell 2 abuts against the end of the second protective shell 3, the limiting groove is aligned with the limiting block 10. Release the push block 11, and through the elastic tension of the limiting spring 9, the end of the limiting block 10 is inserted into the interior of the limiting groove, preventing the connection between the first protective shell 2 and the second protective shell 3 from loosening and improving the stability of the connection between the first protective shell 2 and the second protective shell 3. At this time, the stop block 6 abuts against the inner wall of the first protective shell 2 and the second protective shell 3 respectively, improving the stability of the connection between the cables and enhancing practicality.
