Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage line connection, in particular to a cable connection component for a low-voltage service wire. Background Technique

[0002] A cable is a conductor covered with an insulating layer, a protective layer, a shielding layer, etc. for transmitting electric power or signal current and signal voltage. It can be divided into high-voltage cables and low-voltage cables according to voltage. Although the cost of low-voltage cable lines is higher and the laying and maintenance are more difficult compared with low-voltage overhead lines and low-voltage overhead insulated lines, due to its characteristics of reliable operation, no utility poles, no occupation of the ground, no visual obstruction, and less influence from the outside world, it is widely used in low-voltage distribution systems. When using low-voltage lines, they need to be butt-jointed, and auxiliary parts are required for connection and fixation during butt-jointing to make them more stable during long-term use.

[0003] In view of this, Chinese Patent No. CN204651499U proposes a cable connection component for a low-voltage service wire, which can effectively avoid the occurrence of secondary faults such as overheating of the pressure contact point, pollution flashover, and grounding caused by poor connection of the service wire. It provides technical support for the power supply reliability and high-quality service of power supply enterprises. However, in the above technical solution, when connecting cables, the component for butt-jointing cables does not have a reinforcement function. During long-term use, due to the weight of the cable itself when it is straightened and butted, it sags, which is easy to cause loosening, thus reducing the safety of the device. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a cable connection component for a low-voltage service wire to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model proposes a cable connection component for a low-voltage service wire, including a first arc-shaped tube and a second arc-shaped tube. One side of the first arc-shaped tube is hinged to one side of the second arc-shaped tube, and a cable connection mechanism that can be reinforced is arranged on the inner wall of the first arc-shaped tube;

[0006] The cable connection mechanism that can be reinforced includes a clamping seat fixed on one side of the inner wall of the first arc-shaped tube. Grooves are opened at both ends of the clamping seat, and a clamping hole is opened on one side of the inner wall of each of the two grooves. A connecting bracket is inserted through the middle position at the top of the clamping seat. Slots are opened at both ends of the bottom of the connecting bracket. A first fixing bolt is inserted through the top of the connecting bracket. An insulating wrapping strip is fixed on the inner wall of the second arc-shaped tube.

[0007] In an example, an annular connection groove is opened at the middle position of the top of the clamping seat, and the outer wall of one end of the connecting bracket is inserted and connected to the inner wall of the annular connection groove.

[0008] In one example, a first screw hole is provided in the middle position at the top of the card seat and located in the annular connection groove, and the outer wall of one end of the first fixing bolt is threadedly connected to the inner wall of the first screw hole.

[0009] In one example, a fixing block is fixedly provided on one side of the outer wall of the first arc-shaped pipe, a limiting groove is provided on one side of the fixing block, and a sliding groove is provided on one side of the outer wall of the second arc-shaped pipe.

[0010] In one example, a slider is slidably provided on the inner wall of the sliding groove, an arc-shaped limiting strip is fixedly provided on one side of the slider, and a limiting block is fixedly provided at one end of the arc-shaped limiting strip.

[0011] In one example, the outer wall of the limiting block is inserted and connected to the inner wall of the limiting groove, a second screw hole is provided on one side of the top of the arc-shaped limiting strip, and a second fixing bolt is inserted through the inner wall of the second screw hole.

[0012] The low-voltage service wire cable connection component proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For this low-voltage service wire cable connection component, place the wires at both ends in the grooves at both ends of the card seat, and snap them into the card holes. Then, turn the first fixing bolt at the upper end of the card seat to lower the connection bracket until the wire connectors at both ends are snapped into the grooves at both ends of the bottom of the connection bracket. Moreover, the first fixing bolt is threadedly connected to the first screw hole, and one end of the connection bracket is pressed and fixed in the annular connection groove, which can ensure the stability of the connection bracket and prevent it from falling off easily. Furthermore, it strengthens the wires, and they are not likely to sag and lose connection due to their own gravity during long-term use, improving the safety of the device.

[0014] 2. For this low-voltage service wire cable connection component, after the service wire is connected, cover the second arc-shaped pipe on the first arc-shaped pipe. Slide the slider in the sliding groove to move the arc-shaped limiting strip until the limiting block at its upper end is snapped into the limiting groove on one side of the fixing block. Then, use the second fixing bolt to screw into the second screw hole to fix the slider, and the arc-shaped pipes can be connected and fixed to each other.

[0024] The cable connection mechanism that can be reinforced includes a card seat 3 fixed on one side of the inner wall of the first arc tube 1. Grooves 4 are opened at both ends of the card seat 3, and card holes 5 are opened on one side of the inner walls of the two grooves 4. A connecting bracket 6 is inserted through the middle position at the top of the card seat 3. Slots are opened at both ends of the bottom of the connecting bracket 6. A first fixing bolt 7 is inserted through the top of the connecting bracket 6. An insulating wrapping strip 8 is fixed on the inner wall of the second arc tube 2.

[0025] An annular connecting groove 9 is opened at the middle position at the top of the card seat 3, and the outer wall of one end of the connecting bracket 6 is inserted and connected to the inner wall of the annular connecting groove 9.

[0026] A first screw hole 10 is opened at the middle position of the top of the card seat 3 located in the annular connecting groove 9, and the outer wall of one end of the first fixing bolt 7 is threadedly connected to the inner wall of the first screw hole 10. After the service cable is inserted into the groove 4 and fixed by the connecting bracket 6, since both the card seat 3 and the connecting bracket 6 are made of metal materials, after being energized, the current can flow, and the outer walls of the first arc tube 1 and the second arc tube 2 are made of insulating materials to prevent electric shock when workers come into contact.

[0027] Further, a fixing block 11 is fixedly provided on one side of the outer wall of the first arc-shaped pipe 1. A limiting groove 12 is formed on one side of the fixing block 11. A sliding groove 13 is formed on one side of the outer wall of the second arc-shaped pipe 2. And the fixing block 11 is located on the outer wall of the first arc-shaped pipe 1. When the arc-shaped limiting strip 15 moves, the limiting block 16 at its upper end can just be inserted into the limiting groove 12.

[0028] Further, a slider 14 is slidably provided on the inner wall of the sliding groove 13. An arc-shaped limiting strip 15 is fixedly provided on one side of the slider 14. A limiting block 16 is fixedly provided at one end of the arc-shaped limiting strip 15.
