Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1-6 The present invention provides the following two preferred embodiments:

[0026] Example 1: A low-voltage power distribution automation controller includes a control box 1, wires 2, protective components, and auxiliary components. The control box 1 houses the power distribution controller. A heat dissipation hole is provided on one side of the control box 1. Wiring holes 3 are equidistantly arranged on the side wall of the control box 1, and positioning holes 4 are equidistantly arranged around the wiring holes 3. The wires 2 pass through the wiring holes 3 and connect to the power distribution controller. Protective components and auxiliary components are located at the positions of the wiring holes 3. Square grooves 6 are equidistantly arranged on the inner wall of the fixing block 5 in the protective component. A limit plate 7 is movably engaged within the square groove 6. A connecting rod 8 is fixedly arranged on the side wall of the limit plate 7, and the connecting rod 8 is fixed through the block. The side wall of block 5 is fixedly connected to the fixing plate 9. A rubber pad 10 is fixedly installed on the side wall of the fixing plate 9, and a spring 11 is installed on the side end of the limiting plate 7. The fixing block 5 is arc-shaped and is symmetrically arranged at the position of the wire hole 3. Positioning posts 12 are fixedly installed at equal intervals on the side wall of the fixing block 5. The positioning posts 12 are inserted into the positioning hole 4. One end of the fixing plate 9 extends into the wire hole 3, and the other end extends into the round hole of the ring 15. The rubber pad 10 is in contact with the wire 2. A first magnetic block 13 is fixedly installed at the end of the positioning post 12, and a second magnetic block 14 is fixedly installed at the bottom end of the positioning hole 4. The first magnetic block 13 and the second magnetic block 14 attract each other.

[0027] In use, the wire 2 is passed through the round hole of the ring 15 and then through the wire hole 3 to connect with the low-voltage power distribution automation controller in the control box 1. After the rubber pad 10 is pressed against the wire 2, the fixing block 5 is moved. After the positioning post 12 is inserted into the positioning hole 4, the first magnetic block 13 and the second magnetic block 14 attract each other, realizing the initial positioning and installation of the fixing block 5. At this time, one end of the fixing plate 9 extends into the wire hole 3 to avoid the wire 2 being damaged by friction with the edge of the wire hole 3 during use, thus extending the service life of the wire 2. The spring 11 pushes the fixing plate 9 to move to ensure that the rubber pad 10 and the wire 2 are tightly fitted, making it convenient for the device to be used with wires 2 of different sizes.

[0028] Example 2: Based on Example 1, the auxiliary component has a circular hole at the center of the ring 15, a threaded groove 16 at the bottom end of the ring 15, and an annular groove 17 on the outer wall of the ring 15. The elastic hook 18 and the external threaded tube 19 are fixedly and equidistantly on the side wall of the control box 1. The inner wall of the external threaded tube 19 is engaged with the fixing block 5. The wire hole 3 is located at the center of the external threaded tube 19, and the elastic hook 18 is located on the outside of the external threaded tube 19. The ring 15 is engaged with the fixing block 5, the wire 2 passes through the circular hole of the ring 15, and anti-slip protrusions are provided on the peripheral wall of the ring 15. The threaded groove 16 is threadedly connected to the external threaded tube 19, and the elastic hook 18 is engaged in the annular groove 17.

[0029] During use, after the initial positioning and installation of the fixing block 5, the periphery of the wire 2 at the wire hole 3 is in contact with the rubber pads 10 on the two fixing blocks 5. Then, the threaded groove 16 is threaded to the external threaded tube 19 and the ring 15 is tightened with the help of the anti-slip protrusion until the elastic hook 18 engages with the ring groove 17 to further fix the position of the ring 15. At this time, the inner wall of the external threaded tube 19 engages with the fixing block 5, and the ring 15 engages with the fixing block 5 to achieve the limiting and fixing of the fixing block 5. One end of the fixing plate 9 extends into the round hole of the ring 15 to avoid the wire 2 from being damaged by friction with the edge of the round hole of the ring 15. At the same time, the rubber pads 10 on the fixing plate 9 can be easily replaced after wear during use.
