DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-Figure 4The utility model discloses a protective component for a reactor, comprising a base 1, a reactor body 2, an upper clamp 3 and a lower clamp 4, the output end and the input end of the reactor body 2 are both connected with a connecting wire 5, the reactor body 2 is connected with a terminal head 6 through the connecting wire 5, a sliding block 7 is slidably installed on the connecting wire 5, one end of the sliding block 7 close to the terminal head 6 is fixedly connected with a fixed block 8, a side of the fixed block 8 close to the terminal head 6 is provided with a positioning member 9, a hexagonal groove 10 and three circular grooves 11 are opened on the top of the side of the lower clamp 4, and a mounting member 12 is provided on the top side of the base 1.

[0025] In this embodiment, after the reactor body 2 is installed by means of the provided mounting member 12, the connection end of the circuit is connected to the terminal head 6. The terminal and the terminal head 6 in the prior art have the same structure and are fixed with bolts. After the connection, the sliding block 7 is pulled so that the sliding block 7 drives the fixed block 8 to move toward the terminal head 6. Subsequently, the position of the line connection end and the terminal head 6 is covered by means of the provided positioning member 9. At the same time, the positioning member 9 positions the fixed block 8 at the position of the line terminal and the terminal head 6, thereby achieving a protective effect.

[0026] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the positioning member 9 includes a rectangular groove 13, which is opened on the side of the sliding block 7 close to the terminal head 6, the bottom side of the rectangular groove 13 is in contact with the bottom side of the terminal head 6, and narrow grooves 14 are opened on the upper and lower side walls of the rectangular groove 13.

[0027] In this embodiment, the rectangular groove 13 provided therein allows the fixed block 8 to cover the line terminal and the terminal head 6 inside when it moves, and the narrow groove 14 is provided to avoid the bolts and nuts used when the terminal head 6 and the line terminal are connected, and at the same time the bolts and nuts are protected inside, so that the line terminal and the terminal head 6 are protected as a whole inside the fixed block 8, thereby achieving a protective effect.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, piston grooves 15 are provided on both side walls of the rectangular groove 13 , and a positioning block 16 is connected to the piston in the piston groove 15 , and the end of the positioning block 16 is spherically arranged.

[0029] In this embodiment, when the positioning block 16 provided therein passes through the terminal head 6 during the movement of the fixing block 8, the width of the lead terminal head 6 is greater than the width of the connecting line 5, and then the positioning block 16 will be squeezed by the side of the terminal head 6, thereby performing piston movement, until the positioning block 16 moves through the narrow groove 14 and the rectangular groove 13 to protect the line terminal and the bolt nut. At this time, the positioning block 16 will reach the wire of the line terminal, thereby relieving the squeezing of the line terminal and the terminal head 6, and then getting stuck at the connection between the wire and the line terminal, achieving the effect of positioning and fixing.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the mounting member 12 includes a driving groove 17, which is opened on the base 1 and located below the hexagonal groove 10. A driving shaft 18 is rotatably connected in the driving groove 17, and a torsion spring 19 is fixedly connected to the outer peripheral wall of the driving shaft 18. The end of the torsion spring 19 is fixedly connected to the inner peripheral wall of the driving groove 17. A hexagonal column 20 is fixedly connected to the top of the driving shaft 18, and the top of the hexagonal column 20 extends upward to the top of the hexagonal groove 10. The hexagonal column 20 and the hexagonal groove 10 are slidably connected. A clamping groove 21 is opened on the top side of the base 1 below the three circular grooves 11, and a clamping column 22 is fixedly connected in the clamping groove 21. The top of the clamping column 22 extends upward to the top of the circular groove 11, and an annular groove 23 is opened on the outer peripheral wall of the clamping column 22.

[0031] In this embodiment, when installing the reactor body 2, the lower clamp 4 is made to form a certain angle with the base 1, and then the hexagonal slot 10 is put on the hexagonal column 20, and then the reactor body 2 is rotated clockwise, and then the circular slot 11 is pressed downward so that the circular slot 11 is put on the clamping column 22. When the reactor body 2 is rotated, the hexagonal slot 10 will drive the hexagonal column 20 to rotate. When the hexagonal column 20 rotates, the drive shaft 18 will be driven to rotate, and the torsion spring 19 will be driven to rotate at the same time. At this time, the torsion spring 19 will generate a certain reaction force. After the circular groove 11 is sleeved on the clamping column 22, the reactor body 2 is pressed down so that the inner wall of the circular groove 11 is aligned with the annular groove 23 on the clamping column 22, and then the reactor is released. The reactor will rotate counterclockwise due to the reaction force of the torsion spring 19, so that the inner wall of the circular groove 11 is clamped in the annular groove 23 on the clamping column 22, and is positioned by the upper and lower side walls in the annular groove 23. At the same time, the clamping column 22 will prevent the torsion spring 19 from continuing to rotate counterclockwise, thereby achieving the effect of positioning the lower clamp 4, thereby achieving the effect of quickly installing the reactor.

[0032] The positioning block 16 is made of insulating material such as insulating resin and insulating hard rubber, wherein the height of the annular groove 23 is the same as the thickness of the inner wall of the circular groove 11 to avoid shaking after the reactor is installed.

[0033] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
