Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cable joint accessories with insulating sleeves, and more specifically, it relates to a high-voltage cable joint accessory with an insulating sleeve. Background Art

[0002] In the existing technology, high-voltage cable joint accessories with insulating sleeves play a crucial role in the power system. They are used to connect cables to ensure the safe transmission of electrical energy. However, there are some problems with these joint accessories during use, especially in terms of fixing to the cable. These problems are mainly manifested in the following aspects:

[0003] First of all, when the existing high-voltage cable joint accessories with insulating sleeves are connected to the cable, complex fixing steps are often required. Since the diameter and shape of the cable may vary, the existing joint accessories may not be able to adapt to all types of cables. This results in that in actual operation, the staff need to spend more time and effort to ensure the firm connection between the joint accessory and the cable. In addition, due to the cumbersome fixing process, misoperations are likely to occur, thus increasing the risk of cable joint failures.

[0004] Secondly, when the existing high-voltage cable joint accessories with insulating sleeves fix the cable, special tools or equipment may be required. These tools or equipment may not be easy to carry or operate, further reducing the convenience of use of the joint accessories. In some cases, the staff may need to wait for the arrival of professional equipment to complete the cable fixing work, which undoubtedly prolongs the installation time of the cable joint and affects the operation efficiency of the entire power system.

[0030] Please refer to Figures 1-5, A high-voltage cable joint accessory with an insulating sleeve, including a joint body 1. The joint body 1 is installed on an external device. A fixing mechanism is provided on the joint body 1.

The fixing sleeve 2 is installed on the joint body 1. The adjusting mechanism is installed on the fixing sleeve 2 and the positioning disk 3. The clamping rod 6 is slidably connected to the positioning disk 3. The fixing disk 4 is installed on the fixing sleeve 2. The clamping rod 6 is slidably connected to the fixing sleeve 2. There are multiple clamping rods 6, and the multiple clamping rods 6 are respectively installed on the pushing disk 5. A spring 101 is installed on the fixing disk 4, and the spring 101 is connected to the pushing disk 5. The clamping mechanism is installed on the fixing sleeve 2 and the clamping head 7. The clamping head 7 abuts against the side wall of the cable body 8. Multiple stop grooves 9 are opened on the side wall of the fixing sleeve 2, and the multiple stop grooves 9 are respectively arranged at equal intervals. The clamping mechanism includes a slider 10. A contraction groove 11 is opened on the side wall of the fixing sleeve 2. The slider 10 is slidably connected to the contraction groove 11. There are multiple contraction grooves 11, and the multiple contraction grooves 11 are respectively symmetrically arranged. The slider 10 is slidably connected in each contraction groove 11. A compression spring 12 is provided on each slider 10, and a fitting plate 13 is provided on the compression spring 12. There are multiple clamping heads 7, and the multiple clamping heads 7 are respectively installed on the fitting plate 13.

The bidirectional sleeve 15 is respectively attached to the upper and lower threaded blocks 14. A hexagonal sleeve 16 is provided on the bidirectional sleeve 15. Tapered strips 17 are symmetrically provided on the inner wall of the bidirectional sleeve 15. The upper and lower threaded blocks 14 are respectively reversely threadedly connected to the tapered strips 17. A sliding plate 18 is provided on each slider 10. A sliding groove 19 is opened on the side wall of the fixing sleeve 2. The sliding plate 18 is slidably connected in the sliding groove 19.

[0031] In this embodiment, when it is necessary to fix the joint and the cable, since the cable passes through the fixing sleeve 2, and then the rotation of the hexagonal sleeve 16 can drive the rotation of the bidirectional sleeve 15. Since the tapered strips 17 are reversely engaged with the upper and lower threaded blocks 14, the slider 10 can be driven to slide reversely and contract along the contraction groove 11.

[0033] In summary, when the overall device is in use or operation: when it is necessary to fix the joint and the cable, since the cable passes through the fixing sleeve 2, and then the rotation of the hexagonal sleeve 16 can drive the rotation of the bidirectional sleeve 15. Since the tapered strip 17 is reversely engaged with the upper and lower threaded blocks 14, the slider 10 can be driven to slide reversely and contract along the contraction groove 11. Under the action of the sliding plate 18 and the sliding groove 19, the stability of the sliding is ensured. Then, multiple sliders 10 contract with each other, and then under the action of the compression spring 12, the fitting plate 13 presses against the side wall of the cable, and the friction force is increased through the clamping joint 7, thus completing the clamping process. When it is necessary to fix the cable after the clamping is completed, first, under the action of the spring 101, the push plate 5 and the clamping rod 6 are driven to slide towards the positioning plate 3, and then the clamping rod 6 is slidably connected to the fixed plate 4 and the positioning plate 3, thus completing the fixation of the bidirectional sleeve 15. When it is necessary to rotate the bidirectional sleeve 15, the clamping rod 6 is stuck in the stop groove 9, thus ensuring the limit of the clamping rod 6.
