Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage cables, and in particular to a flexible and shock-resistant low-voltage cable. Background Art

[0002] Low-voltage cable is a type of cable in the prior art. According to the different current powers transmitted, cables are divided into high-voltage cables, medium-low-voltage cables and low-voltage cables. The conductors of low-voltage cables are thinner, and the differences among low-voltage cables are also large. The most obvious difference is between flexible low-voltage cables and ordinary low-voltage cables. The conductors of flexible low-voltage cables are made of extremely fine copper or aluminum wire strands, which makes the low-voltage cable as a whole relatively soft and easy to deform. Flexible low-voltage cables are often used to install on electronic equipment or mechanical equipment to transmit electrical energy to electronic equipment or mechanical equipment.

[0003] In real life, after the flexible low-voltage cable is installed on mechanical equipment or other electrical equipment, because when the flexible low-voltage cable is used for electrical connection, the protective layer, wrapping layer and insulation layer of the flexible low-voltage cable are stripped off, and the conductor is directly installed on the corresponding electrical equipment. Because the conductor of the flexible low-voltage cable is copper wire or aluminum wire, but the strength of copper wire and aluminum wire is poor, the copper wire and aluminum wire are rolled into multiple strands and installed with the electrical equipment. At this time, the bearing force of the flexible low-voltage cable is basically all on the conductor of the flexible low-voltage cable. However, when the flexible low-voltage cable is used in some earthquake-prone belts, it is usually accompanied by obvious vibration. At this time, during the vibration of the electrical equipment, it is easy for the electrical connection between the flexible low-voltage cable and the electrical equipment to loosen, thereby cutting off the normal transmission of electric energy, affecting the normal use of the electrical equipment installed in the earthquake-prone belt, and also affecting the normal use of other electrical equipment subsequently transported to the earthquake-prone belt.

[0014] The working principle and beneficial effects of the present invention are: In the present invention, when it is necessary to electrically connect the flexible conductor to the electrical device, firstly, glue is applied to the receiving groove of the mounting support plate, and the mounting support plate is fixed to the outer wall of the electrical device by the glue, and then the sliding frame is moved on the diamond-shaped support rod through the diamond-shaped cylinder, and the sliding frame and the electrical device are connected by the elastic hook and the connecting piece, and then the diamond-shaped support rod is driven into the diamond-shaped fixing piece, so that the diamond-shaped support rod is kept fixed in the diamond-shaped fixing piece. Because the diamond-shaped support rod and the filling sleeve are both located in the protective layer and the wrapping layer, after the diamond-shaped support rod is fixed in the diamond-shaped fixing piece, the entire filling sleeve, the flexible conductor, the protective layer and other objects are also in contact with the sliding frame, and then the flexible conductor is electrically connected to the electrical device, so that the main connection bearing force acts on the connection and installation assembly between the sliding frame and the electrical device, thereby effectively preventing the problem of poor contact or even falling off between the flexible conductor and the electrical device under vibration environment factors; In the present invention, since the production lengths of objects such as the flexible conductor, the protective layer and the filling sleeve in the production process are relatively long, in actual use, the flexible conductor, the protective layer and the closed ring sleeve may be cut off for use. The sliding frame is sleeved on the outside of a plurality of diamond-shaped support rods through the diamond-shaped cylinder. However, in order to make the diamond-shaped support rods have a sufficient operating length, it is necessary to strip the corresponding area of ​​the filling sleeve on the outside of the diamond-shaped support rods. By adjusting the positions of the mounting member and the stripping wheel, the annular blade arranged on the outer wall of the stripping wheel cuts the filling sleeve. Then, in the process of moving the sliding frame, the stripping wheel divides the filling sleeve into two parts, and the separated filling sleeve parts are discharged through the corresponding separation sleeves, thereby completing the stripping work of the filling sleeve, and facilitating the improvement of the convenience of using the diamond-shaped support rods. Therefore, in actual use, the flexible and shock-resistant low-voltage cable can effectively avoid the connection force acting between the flexible conductor and the electrical equipment when the electrical connection is made between the flexible conductor and the electrical equipment, thereby solving the problem that the flexible conductor is easy to fall off during the vibration of the electrical equipment.

The inner wall of the diamond cylinder 7 fits with the diamond support rods 5. Whether it is driving the sliding frames 6 originally slidably arranged on the diamond support rods 5 to move, or after cutting the diamond support rods 5, the sliding frames 6 are inserted into the outer sides of the diamond support rods 5 again, the diamond cylinder 7 and the sliding frames 6 are fit, so that the diamond cylinder 7 and the sliding frames 6 move on the diamond support members, and the friction between the diamond cylinder 7 and the diamond support rods 5 prevents the sliding frames 6 from moving randomly on the diamond support rods 5.

Mounting members 13 are arranged on both sides of the interior of the sliding frame 6. A screw moving structure is arranged between the mounting member 13 and the sliding frame 6. The screw moving structure includes a rotating screw 17 and a sliding rod 18. The rotating screw 17 is threadedly connected to the sliding frame 6, and the rotating screw 17 is rotatably connected to the mounting member 13.

A fixing screw hole 19 is opened on the row sleeve 16. When the protective layer 1, the flexible conductor 3 and the filling sleeve 4 are cut and used, the protective layer 1 and the wrapping layer 2 are peeled off at this time, so that the filling sleeve 4 and the flexible conductor 3 are exposed, but the outer diameter of the filling sleeve 4 is small, so it is not convenient to strip the filling sleeve 4, and when the filling sleeve 4 needs to be peeled off, the filling sleeve 4 and the flexible conductor 3 are exposed. When the diamond support rod 5 in the sleeve 4 is exposed, first move the diamond cylinder 7 on the sliding frame 6 to the outside of the diamond support rod 5, rotate the rotating screws 17 on both sides, adjust the positions of the mounting member 13 and the wire stripping wheel 14 in the sliding frame 6, and then make the annular blade 15 provided on the wire stripping wheel 14 cut the filling sleeve 4, and then divide the filling sleeve 4 into two parts, so that each filling sleeve 4 is moved to the corresponding row sleeve 16, and after the operator fixes the cut part of the filling sleeve 4 by hand, pull the sliding frame 6 to move on the surface of the diamond support rod 5, so that the wire stripping wheel 14 will The filling sleeve 4 is split, and the bottom of the partition sleeve 16 is shovel-shaped, so that the split part of the filling sleeve 4 can be moved into the partition sleeve 16.

The diamond-shaped fixing member 20 is fixedly connected to the rotating shaft 23, and a reversal limiting structure is provided between the rotating shaft 23 and the rotating sleeve 22. When it is necessary to fix the diamond-shaped support rod 5 to the sliding frame 6, the diamond-shaped support rod 5 is first bent and extended into the diamond-shaped fixing member 20, and then the diamond-shaped fixing member 20 is flipped over so that the diamond-shaped fixing member 20 and the rotating shaft 23 are flipped downwards between the two rotating sleeves 22, and the diamond-shaped support rod 5 is bent so that the diamond-shaped support rod 5 and the diamond fixing member 20 are kept fixed; The reverse limit structure includes a connecting sleeve 24, a rotating shaft 25, a rotating shaft seat 26 and a spring damper 27.

However, when the rotation of the connecting sleeve 24 is stopped, the sliding seat 29 is made to slide on the limit plate 28 through the spring damper 27, pushing the limit plate 28 into the corresponding slope groove. If the rotating shaft 23 is reversed, the limit plate 28 will enter the slope groove, and the limit plate 28 will contact the inner wall of the slope groove, so that the limit plate 28 is engaged with the slope groove, making it less likely for the rotating shaft 23 to have a rotation reset problem.

The diamond support rod 5 is bent so that the diamond support rod 5 and the diamond fixing member 20 are kept fixed. During the rotation of the connecting shaft sleeve 24, there is no engagement between the connecting shaft sleeve 24 and the limit plate 28. However, when the rotation of the connecting shaft sleeve 24 is stopped, the sliding seat 29 is made to slide on the limit plate 28 through the spring damper 27, and the limit plate 28 is pushed into the corresponding slope groove, so that the limit plate 28 and the slope groove on the connecting shaft sleeve 24 are engaged. Finally, the connector 9 is brought into contact with the inner arc surface of the elastic hook 11 to connect the sliding frame 6 with the elastic hook 11, the sliding frame 6 is suspended by installing the support plate 10, and the flexible conductor 3 is electrically connected to the electrical device.
