Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a branch cable with a protective function. Background Art

[0002] Branch cables are cables that connect the power distribution network of power equipment. They are responsible for transmitting the power drawn from the trunk cable or distribution box to each user or device. As a specially designed cable system, branch cables have significant advantages such as easy installation, compact structure and reliable power supply. Branch cables, as important components connecting the power distribution network of power equipment, play an important role in the fields of electrical engineering and construction.

[0003] At present, when installing traditional branch cables, the trunk cable and the branch cable thereon are connected by a branch connector. The branch connector of the prior art is a prefabricated shell with fireproof performance. During installation, the trunk cable and the branch cable are fixed inside the branch connector, and then the shells are connected by bolts or other fastening methods, thus completing the installation operation of the branch cable. In actual use, this installation method for branch cables, on the one hand, will generate a large amount of heat at the connection of the branch cable when the load is too large. The accumulation of this heat will cause damage to the branch connector, thereby exposing the branch cable core and increasing the danger; on the other hand, because the trunk cable and the branch cable are both fixed inside the branch connector, the branch cable is fixed in a fixed direction, which cannot meet the needs of cable routing installation or use during use, resulting in damage to the branch cable.

On the other hand, the protection between the upper protective shell 3 and the lower protective shell 4 can be improved, and the entry of external impurities can be reduced, and the use effect is good.

[0041] The center of the side walls of the upper protective shell 3 and the lower protective shell 4 are both fixedly connected with a side shell 6, a conductive sleeve 7 is sleeved on the wire core of the main cable 1 located at the side shell 6, a fuse conductive component 8 is fixedly connected to the conductive sleeve 7, and the fuse conductive component 8 includes a main conductive column 15, a circular groove 16 is opened on the side of the main conductive column 15 away from the conductive sleeve 7, a fuse column 17 is fixedly connected in the circular groove 16, and a movable conductive column 18 is fixedly connected to the other end of the fuse column 17, a spring 19 is sleeved on the fuse column 17, one end of the spring 19 is fixedly connected to the inner wall of the circular groove 16, and the other end of the spring 19 is fixedly connected to the movable conductive column 18;

[0042] In the present technical solution, when the load on the branch cable 2 is too large, a large amount of heat will be generated on the main conductive column 15 and the movable conductive column 18, and the heat will melt the fuse column 17. At this time, under the action of the spring 19, the movable conductive column 18 is retracted into the circular groove 16, so that the branch cable 2 and the main cable 1 are disconnected, thereby avoiding damage caused by excessive load and improving safety.

[0043] Furthermore, a slot 33 is provided on the side of the main conductive column 15 away from the circular groove 16, and one side of the conductive sleeve 7 is inserted into the slot 33.

[0045] The same circular sleeve 9 is threadedly connected to the outer wall of the two side shells 6, and a movable component 10 is arranged on the side of the circular sleeve 9 away from the side shell 6. The branch cable 2 is fixedly installed on the movable component 10. The movable component 10 includes a movable sleeve 20. An annular groove 21 is opened on the inner wall of the movable sleeve 20. An annular plate 22 is fixedly connected to the outer wall of the circular sleeve 9. The movable sleeve 20 is sleeved on the circular sleeve 9 and the annular plate 22 is movably connected to the annular groove 21.

A wear-resistant conductive plate 24 is fixedly connected to the inner wall of the connecting sleeve 23. The wear-resistant conductive plate 24 is fixedly connected to the core of the branch cable 2;

[0046] In the technical solution, when the branch cable 2 is installed or adjusted, the branch cable 2 drives the movable sleeve 20 to rotate through the wear-resistant conductive plate 24 and the connecting sleeve 23, so that the annular plate 22 rotates in the annular groove 21. Because the branch cable 2 is connected to the wear-resistant conductive plate 24, it is ensured that the power transmission operation is realized while the branch cable 2 rotates, thereby effectively avoiding damage caused by the installation and adjustment of the branch cable 2, and further improving the protection effect;

[0047] The circular sleeve 9 is located between the fuse conductive component 8 and the movable component 10 and is provided with a gas-filled insulating component 11.

[0048] In the present technical solution, insulating inert gas is filled into the gas cylinder 37. When the movable conductive column 18 is separated from the wear-resistant conductive plate 24, the insulating elastic ring 26 expands under the action of the inert gas in the gas cylinder 37. The insulating elastic ring 26 fills the position between the movable conductive column 18 and the wear-resistant conductive plate 24, thereby further disconnecting the power supply of the distribution cable 2 and avoiding damage to the entire structure, thereby achieving good protection effect.

[0049] Working principle: When the branch cable is in use, the insulation layer is stripped at a suitable position on the main cable 1, and the conductive sleeve 7 is sleeved on the core of the main cable 1, the slot 33 on the main conductive column 15 is plugged with the conductive sleeve 7, and the second screw 34 is screwed into the threaded hole to achieve the locking between the conductive sleeve 7 and the main cable 1, and the conductive sleeve 7 and the main conductive column 15. Then the upper protective shell 3 and the lower protective shell 4 are sleeved on the main cable 1, and the conductive sleeve 7 is located inside the side shell 6. At this time, the positioning plate 32 is inserted into the positioning groove 31, and the bolt 29 is passed through the fixing plate 28. The upper protective shell 3 and the lower protective shell 4 are sleeved on the main cable 1, and the conductive sleeve 7 is located inside the side shell 6. At this time, the positioning plate 32 is inserted into the positioning groove 31, and the bolt 29 is passed through the fixing plate 28. The upper protective shell 3 and the lower protective shell 4 are tightened by the nut. The locking installation between the protective shell 3 and the lower protective shell 4 is carried out by rotating the first screw 14 through an external tool, so that the first screw 14 drives the arc plate 13 to move, so that the arc plate 13 pushes out of the arc groove 12, and the conical block 36 on the arc plate 13 is inserted into the insulating layer of the main cable 1 to achieve stable locking between the upper protective shell 3 and the lower protective shell 4 and the main cable 1, thereby improving the installation reliability on the main cable 1, thereby avoiding the exposure of the wire core due to looseness and improving the protection. Then, the branch cable 2 is passed through the movable sleeve 20 and the connection sleeve 23 and the wear-resistant conductive plate 24 are fixedly connected, and then the conical block 36 on the arc plate 13 is inserted into the insulating layer of the main cable 1 to achieve stable locking between the upper protective shell 3 and the lower protective shell 4 and the main cable 1, thereby improving the installation reliability on the main cable 1, thereby avoiding the exposure of the wire core due to looseness and improving the protection. Then, the branch cable 2 is passed through the movable sleeve 20 and the connection sleeve 23 is fixedly connected with the wear-resistant conductive plate 24, and then the conical block 36 on the arc plate 13 is inserted into the insulating layer of the main cable 1. The sleeve 9 is screwed onto the side shell 6, so that the inner wall of the sleeve 9 is pressed against the main conductive column 15. At this time, the movable conductive column 18 is inserted into the connecting sleeve 23, and the movable conductive column 18 contacts the wear-resistant conductive plate 24, completing the connection of the branch cable 2. The gas cylinder 37 filled with insulating inert gas is screwed into the fixed shell 27, and the gas enters the insulating elastic ring 26 through the airway 30. The insulating elastic ring 26 expands to fill the space between the main conductive column 15 and the connecting sleeve 23, completing the installation operation of the branch cable. When the load on the branch cable 2 is too large, the main conductive column 15 and the movable conductive column 18 will generate A large amount of heat will melt the fuse column 17. At this time, the movable conductive column 18 is retracted into the circular groove 16 under the action of the spring 19, so as to disconnect the branch cable 2 from the main cable 1, avoid damage caused by excessive load, and improve safety. After the movable conductive column 18 is separated from the wear-resistant conductive plate 24, the insulating elastic ring 26 expands under the action of the inert gas in the gas cylinder 37, and fills the position between the movable conductive column 18 and the wear-resistant conductive plate 24, so as to further disconnect the power of the branch cable 2, avoid damage to the entire structure, and have a good protection effect.
