Description

Technical Field

[0001] This utility model relates to the field of power switch technology, and more specifically, to a mechanical power switch. Background Technology

[0002] Mechanical power switches, as the basic components of circuit control, are widely used in industrial equipment, household appliances and power systems. Traditional mechanical switches mainly rely on the opening and closing of physical contact points to achieve circuit control. Their structure usually includes three main parts: operating mechanism, contact system and housing. With the development of electrical equipment, the performance requirements of switches are constantly increasing, and existing mechanical switches have revealed many technical defects in long-term use.

[0003] In existing technologies, the tactile feedback and operational comfort of mechanical switches need improvement. Most products use simple spring reset mechanisms, which lack a clear sense of position during operation and are prone to incorrect operation. Existing mechanical switches generally suffer from excessive operating force and easy wear of contacts. When the switch is frequently operated, the mechanical friction between the moving and stationary contacts will cause the contact surface to wear gradually and the contact resistance to increase.

[0009] The present invention is further configured such that a sliding block is fixedly provided inside the housing, and a sliding groove is provided on the adjusting block to cooperate with the sliding block, thereby restricting the movement direction of the adjusting block.

[0010] The present invention is further configured such that a clamping frame is provided on the back plate, and two sets of clamping frames are symmetrically arranged. The first conductive block and the second conductive block are both slidably disposed in the clamping frame. A clamping spring is provided between the first conductive block and the back plate and between the second conductive block and the back plate, so that the first conductive block and the second conductive block have an upward elastic force, thereby improving the connection stability between the first conductive block and the second conductive block and the conductive plate.

[0011] The present invention is further configured such that insulating rubber pads are symmetrically provided on the back of the first conductive block and the second conductive block, and the first conductive block and the compression spring are separated by the insulating rubber pads, so as to facilitate the insulation of the first conductive block and the second conductive block.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a mechanical power switch, which has the following advantages:

[0017] 1. The moving plate drives the moving block and the moving rod to move. In cooperation with the moving groove and tilting groove on the adjusting block, the position of the adjusting block is adjusted. The adjusting block drives the conductive plate to move. When the conductive plate contacts the first conductive block and the second conductive block, the power line and the connecting line are connected, and the power supply is controlled. The perpendicular contact between the first conductive block, the second conductive block and the conductive plate reduces friction and wear.

[0018] 2. By setting the first conductive block and the second conductive block on the clamping frame and supporting the first conductive block and the second conductive block by the elastic force of the clamping spring, the connection stability and tightness between the first conductive block and the conductive plate and between the second conductive block and the conductive plate are improved.

[0019] 3. By pressing the lever, the limiting plate and the limiting rod move, causing the limiting rod to retract into the lever, which facilitates the movement of the lever on the housing. The cooperation between the limiting rod and the first and second limiting holes facilitates the control of the switch. The limiting spring provides elastic force to the pressing rod, which can provide feedback to the user's fingers and make it easy to identify the position of the lever. Attached Figure Description

[0029] Please see Figures 1-5 A mechanical power switch includes a power supply body 1, which includes a housing 2 and a back plate 3. A movable plate 4 is provided on the housing 2, and a lever 5 is provided at the top of the movable plate 4. A limiting device is provided between the lever 5 and the housing 2. A movable block 6 is provided at the bottom of the movable plate 4, and a movable rod 7 is provided on the movable block 6. An adjusting block 8 is slidably provided inside the housing 2. The adjusting block 8 is provided with a moving groove 9 that cooperates with the movable block 6, and also with an inclined groove 10 that cooperates with the movable rod 7. A conductive plate 11 is provided at the bottom of the adjusting block 8. A power cord 12 and a connecting wire 13 are provided on the back plate 3. A first conductive block 14 is electrically connected to the power cord 12, and a second conductive block 15 is electrically connected to the connecting wire 13. Inside the housing 2... A movable frame 16 is symmetrically arranged, and a movable plate 4 is slidably arranged on the movable frame 16. A sliding block 17 is fixedly arranged inside the housing 2. A sliding groove 18 that cooperates with the sliding block 17 is provided on the adjusting block 8. A pressing frame 19 is provided on the back plate 3. Two sets of pressing frames 19 are symmetrically arranged. The first conductive block 14 and the second conductive block 15 are both slidably arranged in the pressing frame 19. A pressing spring 20 is provided between the first conductive block 14 and the back plate 3 and between the second conductive block 15 and the back plate 3. Insulating rubber pads 21 are symmetrically arranged on the back of the first conductive block 14 and the second conductive block 15. The first conductive block 14 and the pressing spring 20 and the second conductive block 15 and the pressing spring 20 are separated by the insulating rubber pads 21.

[0030] In this embodiment, during use, the power cord 12 is electrically connected to the first conductive block 14, and the connecting wire 13 is electrically connected to the second conductive block 15. When conducting electricity to the first conductive block 14 and the second conductive block 15, the user flicks the lever 5 with their finger. The lever 5 drives the moving plate 4 to move on the moving frame 16. The moving plate 4 drives the moving block 6 and the moving rod 7 to move. The moving block 6 moves on the moving groove 9, and the moving rod 7 moves on the inclined groove 10. Under the combined action of the moving rod 7 and the inclined groove 10, the adjusting block 8 is limited by the sliding block 17 and the sliding groove 18. The action moves the conductive plate 11 to press the first conductive block 14 and the second conductive block 15. At the same time, when the adjusting block 8 and the conductive plate 11 are pressed down, they squeeze the first conductive block 14 and the second conductive block 15 to move on the pressing frame 19 and compress the pressing spring 20. The pressing spring 20 gives the first conductive block 14 and the second conductive block 15 an opposite elastic force, thereby improving the connection stability between the first conductive block 14 and the second conductive block 15 and the conductive plate 11. By setting the insulating rubber pad 21, it is easy to insulate the first conductive block 14 and the second conductive block 15.

[0031] Please see Figure 5 As one embodiment of the limiting device: the limiting device includes a limiting rod 22, which is symmetrically slidably disposed on the lever 5. The housing 2 is provided with a first limiting hole 23 and a second limiting hole 24 that cooperate with the limiting rod 22. The lever 5 is provided with a limiting groove 25. The two limiting rods 22 are fixedly provided with limiting plates 26 in the limiting grooves 25. The other end of the limiting plate 26 is provided with a pressing rod 27 on the lever 5. A limiting spring 28 is provided between the limiting plates 26.

[0032] More specifically, when moving lever 5, the finger squeezes the pressing rod 27, which in turn drives the limiting plate 26 to squeeze the limiting spring 28. The limiting plate 26 then causes the limiting rod 22 to retract into lever 5, causing the limiting rod 22 to leave the first limiting hole 23. When lever 5 is moved, and the limiting rod 22 is aligned with the second limiting hole 24, the limiting plate 26, under the elastic force of the limiting spring 28, causes the limiting rod 22 and the pressing rod 27 to pop out. When the pressing rod 27 pops out, it provides feedback to the user's finger, allowing the user to know that the lever 5 has been moved to the correct position.

[0033] In summary, during use or operation of the entire device: When in use, the power cord 12 is electrically connected to the first conductive block 14, and the connecting wire 13 is electrically connected to the second conductive block 15. When conducting electricity to the first conductive block 14 and the second conductive block 15, the user's finger moves the lever 5. The lever 5 moves the moving plate 4 on the moving frame 16, which in turn moves the moving block 6 and the moving rod 7. The moving block 6 moves on the moving groove 9, and the moving rod 7 moves on the inclined groove 10. The adjusting block 8, under the combined action of the moving rod 7 and the inclined groove 10, moves through the sliding block 17 and the sliding groove 10. Under the limiting action of 8, the adjustment block moves, causing the conductive plate 11 to press the first conductive block 14 and the second conductive block 15. At the same time, when the adjustment block 8 and the conductive plate 11 are pressed down, they squeeze the first conductive block 14 and the second conductive block 15 to move on the pressing frame 19 and compress the pressing spring 20. The pressing spring 20 gives the first conductive block 14 and the second conductive block 15 a reverse elastic force, thereby improving the connection stability between the first conductive block 14 and the second conductive block 15 and the conductive plate 11. By setting the insulating rubber pad 21, it is easy to insulate the first conductive block 14 and the second conductive block 15.

[0034] When the lever 5 is moved, the finger squeezes the pressing rod 27. The pressing rod 27 drives the limiting plate 26 to squeeze the limiting spring 28. The limiting plate 26 drives the limiting rod 22 to retract into the lever 5, so that the limiting rod 22 leaves the first limiting hole 23. When the lever 5 is moved, when the limiting rod 22 is aligned with the second limiting hole 24, the limiting plate 26 drives the limiting rod 22 and the pressing rod 27 to pop out under the elastic force of the limiting spring 28. When the pressing rod 27 pops out, it provides feedback to the user's finger, so that the user knows that the lever 5 has moved to the correct position.
