Specific implementation

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the scope of protection of the utility model.

[0022] The utility model provides a kind of technical scheme: as Figures 1-7 As shown in the drawing, a kind of bypass switching switch of switching stability, including box body 1, still including rotating installation in the inner wall of box body 1 rotating rod 6, fixed installation on the outer side of rotating rod 6 insulating sleeve 7 and the terminal lug 5 of one side fixed installation of insulating sleeve 7, fixed installation on the side of insulating mounting plate 8 contact plate 9.

[0023] Insulating sleeve 7 is used to cooperate the rotation of rotating rod 6 to realize the control and adjustment of the position of terminal lug 5 in box body 1, to facilitate the switching work of switch in different positions, and contact plate 9 is the interface of terminal lug 5.

[0024] The inside of the box body 1 is provided with an anti-misoperation assembly, the anti-misoperation assembly comprises a vertical groove 10, the vertical groove 10 is arranged on the top end outer arc surface of the rotating rod 6, the top end outer side of the rotating rod 6 is sleeved with a sleeve ring 11, the inner arc surface of the sleeve ring 11 is fixedly installed with a square block 12, the side wall of the sleeve ring 11 is fixedly connected with a handle 13, the top inner wall of the box body 1 is penetrated and fixedly installed with a fixed sleeve 14, the bottom inner wall of the fixed sleeve 14 is rotatably installed with a rotating ring 15, the top end of the rotating ring 15 is fixedly connected with an extension rod 16, the outer side of the extension rod 16 is sleeved with a spring 18, the top end of the extension rod 16 is fixedly installed with a fixed ring 17, the upper surface of the fixed ring 17 is provided with a limiting groove 19, and the side wall of the handle 13 is fixedly installed with a protruding block 20.

[0025] The square block 12 is in sliding fit with the vertical groove 10, so that the sleeve ring 11 can move in the vertical direction on the top end outer side of the rotating rod 6, and meanwhile, the middle segment of the handle 13 penetrates through the fixed sleeve 14 and is in movable fit with the fixed sleeve 14, so that in use, the handle 13 is lifted upward by a distance, so that the protruding block 20 moves upward and is separated from the limiting groove 19, at this time, the handle 13 is rotated around the axis of the fixed sleeve 14 as the rotation center, so that the rotating rod 6 rotates, that is, the angle of the terminal lug 5 on one side of the insulating sleeve 7 is changed, thereby realizing the communication work of different lines. In this process, due to the arrangement of the limiting groove 19, after rotating to the working angle, the handle 13 can be self-locked under the elastic force of the spring 18 after being put down, so that in actual use, it has a certain protection effect on external misoperation, and the relative stability of circuit communication and the safety of power utilization are maintained.

[0026] The box body 1 is fixedly installed with the incoming terminal 2 and the socket 3 on the left and right sides, the inner wall of the box body 1 is fixedly installed with the insulating mounting plate 8, the outgoing terminal 4 is fixedly installed on the side, away from the inner wall of the box body 1, of the insulating mounting plate 8, and the outgoing terminal 4 is rotatably connected with the terminal lug 5 on one side.

[0027] The incoming terminal 2 and the socket 3 can be electrically connected with the external cable respectively, and the outgoing terminal 4 is electrically connected with the terminal lug 5, so that after the terminal lug 5 is switched, the incoming terminal 2 and the outgoing terminal 4 and the socket 3 and the outgoing terminal 4 can be electrically connected, thereby realizing the switching work of the switch.

[0028] The terminal lug 5 is arranged in a V shape, and the connection point of the terminal lug 5 and the outgoing terminal 4 is arranged at the top end of the V-shaped terminal lug 5.

[0029] The V-shaped connecting piece 5 can switch the circuits on the left and right sides of the housing 1 as the rotating rod 6 rotates. The included angle of the V-shaped structure of the connecting piece 5 is set to 90°, so that the connecting piece 5 can make a sufficiently stable contact with the contact plate 9 during circuit switching to maintain the stable connection of the circuit. It is worth noting that the contact plate 9 is made of two sets of U-shaped elastic sheets, and the two sets of contact plates 9 are in close contact with each other, so as to ensure that the contact plate 9 and the connecting piece 5 can maintain a stable contact and realize the circuit connection.

[0030] Please see Figures 6-7 The rotating ring 15 is arranged in an L-shape, and the side wall of the handle 13 is provided with an annular groove that is adapted to the rotating ring 15, and the rotating ring 15 rotates in conjunction with the annular groove.

[0031] The swivel 15 provides vertical position support for the telescopic rod 16 and the spring 18, and the swivel 15 and the fixed sleeve 14 can rotate relative to each other. Therefore, when the handle 13 is rotated, its vertical reset effect will not be affected. At the same time, the spring 18 will not bend laterally due to the influence of the telescopic rod 16.

[0032] The fixing ring 17 is fixedly connected to the inner wall of the fixing sleeve 14, and the size of the limiting groove 19 is adapted to the protrusion 20. The diameter of the central cavity of the fixing ring 17 is larger than the outer diameter of the handle 13.

[0033] The retaining ring 17 provides a mounting position for the telescopic rod 16 and the swivel 15 in the vertical direction, and the arrangement of the retaining ring 17 does not interfere with the movement of the handle 13.

[0034] There are two sets of protrusions 20, which are mirror images of each other on both sides of the grip 13. There are six limiting grooves 19, which are divided into two fan-shaped areas on both sides of the center of the fixing ring 17.

[0035] After the protrusion 20 enters the limiting groove 19, the two work together to limit the position of the handle 13, maintain the current position, and prevent displacement due to external interference, which would affect the stable connection between the wiring piece 5 and the contact plate 9. Furthermore, the included angle between the two ends of one of the fan-shaped areas is set to 90°. Therefore, when the protrusion 20 is in the limiting groove 19 at the center, the wiring piece 5 is separated from the contact plates 9 on the left and right sides, and the device is in a power-off state. After the rotating rod 6 rotates 45° to the left, the protrusion 20 is in the limiting groove 19 at the leftmost end. At this time, the wiring piece 5 contacts the contact plate 9 on the left side of the housing 1, and the circuit connection between the inlet terminal 2 and the outlet terminal 4 is realized. When the rotating rod 6 rotates 45° from the center to the right, the protrusion 20 is in the limiting groove 19 at the rightmost end. At this time, the wiring piece 5 contacts the contact plate 9 on the right side of the housing 1, and the circuit connection between the socket 3 and the outlet terminal 4 is realized.

[0036] The handle 13 is arranged in an "E" shape, and the bottom end of the rotating rod 6 is rotatably connected to the inner wall of the bottom end of the box 1 through a cross rod, and the rotating axis of the rotating rod 6 is arranged on the same vertical line as the rotating axis of the terminal lug 5 and the axis of the fixed sleeve 14.

[0037] When the handle 13 rotates, the rotating rod 6 and the handle 13 are both arranged around the axis of the fixed sleeve 14 as the rotation center, so that the V-shaped terminal lug 5 can be switched between the contact plates 9 on both sides of the insulating mounting plate 8, ensuring stable connection between the terminal lug 5 and the contact plates 9 while facilitating the switching action of the staff, improving the stability of the device operation.

[0038] Working principle: when the line needs to be switched, the operator first lifts the handle 13 upward. The handle 13 slides upward in the vertical slot 10 of the rotating rod 6 through the sleeve ring 11 and the square block 12, and at the same time, the spring 18 is compressed, so that the protrusion 20 on the side wall of the handle 13 is separated from the limiting groove 19 of the fixed ring 17. At this time, the handle 13 can freely rotate around the axis of the fixed sleeve 14. The operator rotates the handle 13, and the handle 13 drives the rotating rod 6 and the insulating sleeve 7 fixed on the rotating rod 6 to rotate together through the sleeve ring 11 and the square block 12. The V-shaped terminal lug 5 on the side of the insulating sleeve 7 rotates together, thereby changing the angular position of the terminal lug 5 in the box 1. When the handle 13 is rotated by 45°, so that one of the contacts of the terminal lug 5 reliably contacts the contact plate 9 on the left side of the insulating mounting plate 8, the circuit is connected through the inlet terminal 2, the contact plate 9, the terminal lug 5 and the outlet terminal 4. When the handle 13 is rotated by 45° to the other side, so that the terminal lug 5 contacts the right side contact plate 9, the circuit is connected through the socket 3, the contact plate 9, the terminal lug 5 and the outlet terminal 4. If the handle 13 is in the middle position, the terminal lug 5 does not contact the contact plates 9 on both sides, and the circuit is in an open state. After switching, the operator releases the handle 13, and under the restoring force of the spring 18, the handle 13 is reset downward, and the protrusion 20 on the side wall of the handle 13 is automatically inserted into the corresponding limiting groove 19 of the fixed ring 17, realizing mechanical self-locking, thereby preventing accidental rotation of the rotating rod 6 due to accidental touch or vibration, ensuring the long-term stability of the electrical contact between the terminal lug 5 and the contact plate 9, and finally realizing the stability and reliability of the bypass switching process.
