[0024] The flame-retardant protective device 2 includes a fixing ring 21. Two fixing rings 21 are fixedly installed on the outside of the cold shrink waterproof joint assembly 6. Two semi-cylinders 23 are provided on the outside of the two fixing rings 21. The side walls of the semi-cylinders 23 are filled with flame-retardant cotton 22.

[0025] Specifically, the two fixing rings 21 are connected to the two semi-cylinders 23 by four screws 25, and two protective components 24 are provided on the outer side of the two semi-cylinders 23 and on both sides of the four screws 25.

[0026] By adopting the above technical solution, workers can connect or separate the two fixing rings 21 and the two semi-cylinders 23 using four screws 25 when needed, thus facilitating the assembly and disassembly of structures such as the semi-cylinders 23.

[0027] Specifically, the protective component 24 includes wear-resistant rubber rings 243, and two wear-resistant rubber rings 243 are provided on the outer side of the two semi-cylinders 23 and on both sides of the four screws 25.

[0028] By adopting the above technical solution, workers can enhance the wear resistance of the joint with wear-resistant rubber ring 243 when needed, thereby reducing the possibility of mutual wear between the joint and the ground and better meeting the needs of the work.

[0029] Specifically, four semi-circular rings 241 are fixedly installed on the outer side of the two semi-circular cylinders 23 and on the inner side of the two wear-resistant rubber rings 243, and threaded rings 242 are fixedly installed on the inner side of the wear-resistant rubber rings 243 and on the outer side of the two semi-circular rings 241.

[0030] By adopting the above technical solution, workers can connect or separate the two wear-resistant rubber rings 243 from the two semi-cylinders 23 using four semi-circular rings 241 and two threaded rings 242 when needed, thus facilitating the loading and unloading of the wear-resistant rubber rings 243.

[0031] In this embodiment, when a connector is required, the worker connects the first cable 1 and the second cable 4 through the cold-shrink waterproof connector assembly 6, tightens the two nylon cable ties 5, and then installs the two semi-cylinders 23 onto the two fixing rings 21 outside the cold-shrink waterproof connector assembly 6 through the screws 25 in the flame-retardant protective device 2. Then, the threaded rings 242 inside the wear-resistant rubber rings 243 in the two protective assemblies 24 are connected to the four semi-cylinders 241 outside the two semi-cylinders 23 through threads. The flame-retardant cotton 22 can block the flame combustion to a certain extent, and the wear-resistant rubber rings 243 can improve the wear resistance of the connector. Then it can be used.

[0032] Example 2:

[0033] The difference between this embodiment and embodiment 1 is that the auxiliary suspension device 3 includes a connecting rope 33, the connecting rope 33 is provided above the second cable 4, and a suspension ring 36 is fixedly connected to the side of the connecting rope 33 away from the semi-cylinder 23.

[0034] By adopting the above technical solution, workers can suspend the joint when needed by using the combination of the suspension ring 36 and the connecting rope 33, thereby better meeting the cable connection needs in different situations.

[0035] Specifically, a threaded block 32 is fixedly connected to the side of the connecting rope 33 near the semi-cylinder 23, and a threaded sleeve 31 is fixedly connected to the side of the semi-cylinder 23 and outside the threaded block 32.

[0036] By adopting the above technical solution, workers can connect or separate the connecting rope 33 from the semi-cylinder 23 using the threaded block 32 and the threaded sleeve 31 when needed, thus facilitating the loading and unloading of the connecting rope 33 and other structures.

[0037] Specifically, the top and bottom of the suspension ring 36 are threaded with screws 34, and the two adjacent sides of the two screws 34 are fitted with clamps 35 via bearings.

[0038] By adopting the above technical solution, the staff can further fix the position of the suspension ring 36 with the screw 34 and the clamp 35 when needed, thereby preventing the suspension ring 36 from falling off accidentally during the suspension process.

[0039] In this embodiment, when the connector needs to be suspended due to cable connection or other reasons, the worker can connect the threaded block 32 on the connecting rope 33 in the auxiliary suspension device 3 to the threaded sleeve 31 on the semi-cylinder 23 via the thread. Then, the suspension ring 36 is hung on the hanging rod or other structure at the suspension position. Then, the two screws 34 are rotated respectively. The screws 34 are threadedly connected to the suspension ring 36, and the screws 34 are bearing connected to the clamping plate 35. The two sides of the clamping plate 35 are in contact with the inner side of the suspension ring 36. Therefore, the two screws 34 drive the two clamping plates 35 to move, thereby clamping the hanging rod or other structure at the suspension position. The suspension is completed, thus better meeting the cable connection needs in different situations.

[0040] The structure and principle of the first cable 1, the second cable 4, the nylon cable ties 5, and the cold-shrink waterproof joint assembly 6 composed of a connecting tube, a first layer of adhesive tape, an intermediate joint body, and a second layer of adhesive tape in this utility model have been disclosed in the waterproof cable cold-shrink intermediate joint disclosed in Chinese patent application number 201721901271.X. Its working principle is to insert the connecting tube into the cable cores of the first and second cables and crimp them. If there are burrs, they are smoothed and cleaned. The first layer of adhesive tape is wrapped around the outside of the treated connecting tube to form an internal waterproof layer. The intermediate joint body is then fitted to tightly hold the cable. The two ends of the intermediate joint body are secured with nylon cable ties to provide additional clamping force. The second layer of adhesive tape is then wrapped around both ends of the intermediate joint body, and the second layer of adhesive tape overlaps with the first cable, the second cable, and the second layer of adhesive tape.

[0041] The working principle and usage process of this utility model are as follows: When a connector is needed, the operator connects the first cable 1 and the second cable 4 through the cold-shrink waterproof connector assembly 6, tightens the two nylon cable ties 5, and then installs the two semi-cylinders 23 onto the two fixing rings 21 outside the cold-shrink waterproof connector assembly 6 through the screws 25 in the flame-retardant protective device 2. Then, the threaded rings 242 inside the wear-resistant rubber rings 243 in the two protective assemblies 24 are connected to the four semi-cylinders 241 outside the two semi-cylinders 23 through threads. The flame-retardant cotton 22 can block the flame combustion to a certain extent, and the wear-resistant rubber rings 243 can improve the wear resistance of the connector. Then it can be used. When it is necessary to suspend the connector due to cable connection or other reasons, the worker can connect the threaded block 32 on the connecting rope 33 in the auxiliary suspension device 3 to the threaded sleeve 31 on the semi-cylinder 23 through the thread. Then, the suspension ring 36 is hung on the hanging rod or other structure at the suspension position. Then, the two screws 34 are rotated respectively. The screws 34 are threadedly connected to the suspension ring 36, and the screws 34 are bearing connected to the clamping plate 35. The two sides of the clamping plate 35 are in contact with the inner side of the suspension ring 36. Therefore, the two screws 34 drive the two clamping plates 35 to move, thereby clamping the hanging rod or other structure at the suspension position. The suspension is completed, thus better meeting the cable connection needs in different situations.
