DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0020] like Figure 1-3 As shown, a low-voltage complete set of powerless compensation device includes a base 1, a terminal box 2, a first conductive plate 3, a second conductive plate 5, a second U-shaped conductive sheet 6, a knife switch 7, a handle 8, and a contact terminal 9. The base 1 is provided with an input terminal, the terminal box 2 is provided on the top of the base 1, a plurality of contact terminals 9 are provided on the terminal box 2, and each contact terminal 9 is connected to the output terminal, the first conductive plate 3 is connected to the input terminal, the first conductive plate 3 is rotatably connected to the first U-shaped conductive sheet 4, the first U-shaped conductive sheet 4 is fixedly connected to the second conductive plate 5, the second conductive plate 5 is rotatably connected to the second U-shaped conductive sheet 6, the rotation axis of the first U-shaped conductive sheet 4 is perpendicular to the rotation axis of the second U-shaped conductive sheet 6, the knife switch 7 is fixedly connected to the second U-shaped conductive sheet 6, and the knife switch 7 can be closed with any contact terminal 9, and the handle 8 is provided on the end of the knife switch 7 facing away from the second U-shaped conductive sheet 6.

[0021] Specifically, after the knife switch 7 is closed with the contact terminal 9, the input end and the output end can be connected. The knife switch 7 can be closed with any contact terminal 9, so that the input end is connected to different output ends. The handle 8 is used to drive the knife switch 7 to swing back and forth, so that the first U-shaped conductive piece 4 rotates on the first conductive plate 3, so that the knife switch 7 can be moved away from or close to the contact terminal 9 to achieve closing or separation. The handle 8 is used to drive the knife switch 7 to rotate, so that the second U-shaped conductive piece 6 rotates on the second conductive plate 5, so that the knife switch 7 can change its angle to correspond to any contact terminal 9, so as to achieve closing with any contact terminal 9.

[0022] Furthermore, the input end includes an input conductive wire 10 and a first fastener 12. A first wire groove 11 is opened at one end of the base 1. One end of the input conductive wire 10 is in the first wire groove 11. The other end of the base 1 is connected to the first conductive plate 3. A first fastener 12 for fastening the cable is provided above the first wire groove 11.

[0023] Specifically, the first fastener 12 fastens the cable in the first wire trough 11, and then connects the cable to the input conductive line 10, which can be conductive to the switch 7 through the input conductive line 10, the first conductive plate 3, the first U-shaped conductive sheet 4, the second conductive plate 5, and the second U-shaped conductive sheet 6.

[0024] Furthermore, the output end includes an output end conductive wire 14 and a second fastener 15. A second wire groove 13 is opened on the side of the terminal box 2. One end of the output end conductive wire 14 is in the second wire groove 13. The other end of the output end conductive wire 14 is connected to the contact terminal 9. A second fastener 15 for fastening the cable is provided at the front of the second wire groove 13.

[0025] Specifically, the second fastener 15 fastens the cable in the second wire duct 13 , so that the cable is connected to the output-end conductive wire 14 , and electricity can be conducted to the cable through the contact terminal 9 and the output-end conductive wire 14 .

[0026] Furthermore, the plurality of contact terminals 9 are distributed in a ring shape, and the center of the ring is the rotation axis of the second U-shaped conductive piece 6 .

[0027] Specifically, when the knife switch 7 rotates through the support of the second U-shaped conductive sheet 6, it can close the circuit with any contact terminal 9. The contact terminal 9 is distributed around the rotation axis center of the second U-shaped conductive sheet 6, so that the knife switch 7 can correspond to any contact terminal 9 after rotation to achieve closing.

[0028] Furthermore, it includes a limit plate 16, which is fixedly connected to the terminal box 2 and is arranged along the top edge of the terminal box 2. The limit plate 16 is provided with a slide groove 18 and a card groove 17 for the handle 8 to rotate and slide in. The limit plate 16 is arc-shaped, and the center of the arc is the rotation axis of the second U-shaped conductive plate 6.

[0029] Specifically, when the handle 8 slides into the slot 17, the knife switch 7 and the contact terminal 9 are closed, and the slot 17 can limit the position to prevent the handle 8 and the knife switch 7 from offset. When the handle 8 moves inside the slot 18, the slot 18 can limit the handle 8 to prevent the handle 8 from rotating too much, thereby ensuring safety.

[0030] Furthermore, the first U-shaped conductive sheet 4 and the first conductive plate 3, as well as the second U-shaped conductive sheet 6 and the second conductive plate 5, are all rotationally connected via a rotating shaft. The rotating shaft can support the rotation of the first U-shaped conductive sheet 4 and the second U-shaped conductive sheet 6 while ensuring the conductivity between the first U-shaped conductive sheet 4 and the first conductive plate 3, as well as the second U-shaped conductive sheet 6 and the second conductive plate 5.

[0031] In the above structure, the input end cable is contacted with the input conductive wire 10, and then the cable is fastened by screwing the first fastener 12. The output end cable is contacted with the output end conductive wire 14, and then the cable is fastened by screwing the second fastener 15. When it is necessary to close the switch, the handle 8 is used to swing the knife 7 so that the knife 7 can change its angle and rotate. Then, when the position of any contact terminal 9 is reached, the handle 8 is pushed to slide it into the slot 17, and the knife 7 is simultaneously snapped into the contact terminal 9, so that the input conductive wire 10, the contact terminal 9 and the output end conductive wire 14 are connected, and the input end and the output end are connected. In this way, it is avoided that the outermost terminal needs to be contacted before the next terminal can be contacted, which causes inconvenience in use.

[0032] The above shows and describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements are intended to fall within the scope of the present application.
