Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-Figure 4The utility model discloses a cable quick connector for a ring network box, comprising a ring network box 1, a bearing bracket 2 is provided inside the ring network box 1, a locking assembly 3 is provided on the top of the bearing bracket 2, a group of copper plates 4 is provided on one side of the bearing bracket 2, a group of copper plates 4 is fixedly connected to multiple cable poles 5, the cable poles 5 are slidably connected to the annular cable connector 6, and the annular cable connector 6 is snap-fitted with the locking assembly 3, the locking assembly 3 comprises a sliding base 301, a snap-fit ​​rod 302 is provided on both sides of the sliding base 301, a locking rod 303 is provided at one end of the sliding base 301, and the locking rod 303 is tightly pressed into the annular cable connector 6. The utility model provides a locking assembly on the top of the bearing bracket, a group of copper plates is provided on one side of the bearing bracket, the copper plates are fixedly connected to multiple cable poles, the cable poles are slidably connected to the annular cable connector, and the annular cable connector is snap-fitted with the locking assembly, and the locking assembly is composed of a sliding base, a snap-fit ​​rod and a locking rod, which effectively avoids the problem of screw stripping. At the same time, even under strong vibration or long-term use, the cable connector can be continuously and stably pressed to ensure that it will not loosen due to external force, and the installation and disassembly capabilities are improved.

[0021] Furthermore, the sliding base 301 is fixedly connected to the top of the bearing bracket 2, and a limit block 304 is provided on the top of the sliding base 301. The limit block 304 is engaged with the locking rod 303 and is firmly fixed to the top of the bearing bracket through the sliding base. A limit block is provided on the top of the sliding base. The limit block is engaged with the locking rod, providing a clear and fixed position for the locking rod. When the locking rod presses the annular cable connector, it can be accurately and stably maintained at the predetermined position and will not be easily offset due to external force, thereby effectively preventing the cable connector from loosening.

[0022] Furthermore, the limit block 304 is provided with a sliding groove, and the sliding groove is slidably connected to the sliding rod 305. One end of the sliding rod 305 is fixedly connected to the locking rod 303. A sliding groove is provided on the limit block, and the sliding groove allows the internal sliding rod to slide freely within a limited range, thereby ensuring the accuracy and controllability of the movement of the locking rod and simplifying the operation process.

[0023] Furthermore, snap-in grooves are provided on both sides of the locking rod 303, and a pressure ring 306 is provided on the inner side of the locking rod 303. The pressure ring 306 is sleeved on one end of the cable pole 5. The snap-in grooves are provided on both sides of the locking rod, and the snap-in grooves cooperate with the limit blocks, so that the locking rod can be stably fixed in a predetermined position and is not easily moved by external forces, thereby ensuring the stability of the cable connection. Secondly, a pressure ring is specially provided on the inner side of the locking rod, which is tightly combined with the locking rod and directly sleeved on one end of the cable pole, so that the pressure ring can apply uniform and continuous pressure to the cable pole, thereby ensuring a tight connection between the cable pole and the annular cable connector.

[0024] Furthermore, a spring 307 is sleeved on one end of the clamping rod 302, and one end of the spring 307 is tightly pressed inside the sliding base 301. One end of the clamping rod 302 is slidably connected to the inside of the sliding base 301. The spring is sleeved on one end of the clamping rod, so that the clamping rod can flexibly perform telescopic movements when subjected to external force, thereby simplifying the installation and disassembly process of the cable connector and improving the convenience of operation. Secondly, one end of the spring is tightly pressed inside the sliding base, ensuring that the elastic force of the spring can be effectively transmitted to the clamping rod, so that it can stably perform telescopic movements and maintain the stability of the cable connection.

[0025] Furthermore, a semi-ring plate 308 is provided on one side of the clamping rod 302, and the semi-ring plate 308 is rotatably connected to the clamping rod 302. The semi-ring plate is added through the clamping rod, and the rotatable connection between the semi-ring plate and the clamping rod allows the semi-ring plate to rotate freely within a certain range, so that it can more flexibly adapt to cable connectors of different shapes and sizes, simplify the installation process, and greatly improve the stability and reliability of the cable connection.

[0026] In this solution, the work flow is as follows: the ring network box has been installed in the predetermined position, and a load-bearing bracket is provided inside. The top of the load-bearing bracket is equipped with a locking assembly, which is a key component to ensure the stability of the cable connection.

[0027] A group of copper plates are installed on one side of the bearing bracket, and a plurality of cable poles are fixedly connected to the copper plates; the cables to be connected are slidably connected to the cable poles through annular cable connectors.

[0028] The ring-shaped cable connector is designed to be snap-fitted with the locking assembly to ensure the stability of the connection; under the guidance of the sliding base, the locking rod is moved into position and tightly pressed onto the ring-shaped cable connector to achieve the locking function.

[0029] The pressure ring on the inner side of the locking rod is sleeved on one end of the cable column to further enhance the stability of the connection.

[0030] Check whether the locking assembly has correctly locked the ring cable connector to ensure the security of the cable connection; the clamping rod provides additional fixing force under the action of the spring to prevent accidental loosening.

[0031] If the cable needs to be adjusted or replaced, the ring cable connector can be released by unlocking the locking assembly, and the half ring plate can be rotated to connect the clamping rod, providing flexible adjustment space and facilitating on-site operation.
