[0029] Example
[0030] like Figure 1-4As shown, an intelligent low-voltage switch proposed by the utility model includes an outer protective shell 1, and also includes a first connecting component 2 and a second connecting component 3 arranged in the outer protective shell 1, and the first connecting component 2 is electrically in contact with the second connecting component 3. The first connecting component 2 includes a fixed rod 21, a sleeve 22, a synchronous plate 23, and a moving block 24. The fixed rod 21 is fixedly connected in the outer protective shell 1, and the position of the fixed rod 21 is fixed. The sleeve 22 is slidably sleeved on the fixed rod 21. The fixed rod 21 is not limited to a cylindrical shape, and can also be set to a prismatic shape, which is convenient for limiting the position when the sleeve 22 slides, so that the sleeve 22 does not rotate when sliding. The synchronous plate 23 is fixedly connected to the outer ring of the sleeve 22, and the synchronous plate 23 moves synchronously with the sleeve 22. The moving block 24 is fixedly connected to one side of the synchronous plate 23, and the moving block 24 moves synchronously with the sleeve 22. The first connection assembly 2 also includes a slide bar 25, a connecting plate 26, a first conductive sheet 27, and a first spring 28. The two groups of slide bars 25 are slidably connected to the moving block 24. The connecting plate 26 disposed on one side of the moving block 24 is fixedly connected to one end of the multiple groups of slide bars 25. The connecting plate 26 is used to prevent the two groups of slide bars 25 from being separated from the moving block 24. The first conductive sheet 27 is fixedly connected to one end of the two groups of slide bars 25 away from the connecting plate 26. The first conductive sheet 27 is limited by the two groups of slide bars 25 and moves smoothly. The first spring 28 is disposed between the moving block 24 and the first conductive sheet 27 and is sleeved on the outer ring of the slide bar 25. When the first conductive sheet 27 is in close contact with the second conductive sheet 34, the sliding sleeve 22 continues to drive the moving block 24 to move downward, thereby compressing the first spring 28. The elastic force released by the first spring 28 drives the first conductive sheet 27 to press the second conductive sheet 34.
[0031] For details, please refer to Figure 2 and Figure 3 The second connection assembly 3 in the above switch includes a fixed frame 31, a sliding plate 32, a connecting frame 33, and a second conductive sheet 34. The U-shaped fixed frame 31 is fixedly connected to the inner wall of the outer protective shell 1, and the position of the fixed frame 31 is fixed. The sliding plate 32 is soldered to the bottom of the fixed frame 31, and the metal tin at the soldering position melts when a short circuit occurs. The sliding plate 32 is slidably connected to the fixed rod 21, and the elastic force of the second spring 45 drives the sliding plate 32 to slide downward after the metal tin melts. The L-shaped connecting frame 33 is fixedly connected to one side of the sliding plate 32, and the connecting frame 33 is used to connect the second conductive sheet 34 to the sliding plate 32. The second conductive sheet 34 is installed on the side of the connecting frame 33 close to the first conductive sheet 27, and the position of the second conductive sheet 34 corresponds to the first conductive sheet 27. The connecting plate 26 and the fixed frame 31 are both connected to the power line through the power connection block, so that the first conductive sheet 27 and the second conductive sheet 34 are in contact to achieve a passage.
[0032] Furthermore, the switch also includes a connecting mechanism 4 for driving the first connecting component 2 to contact the second connecting component 3 to realize the passage. The connecting mechanism 4 includes a limit ring 41, a rotating sleeve 42, a moving plate 43, and a handle 44. Two sets of limit rings 41 are fixedly connected to the sliding sleeve 22, and the limit ring 41 moves synchronously with the sliding sleeve 22. The rotating sleeve 42 arranged between the two sets of limit rings 41 is rotatably connected to the outer ring of the sliding sleeve 22, and the rotating sleeve 42 is kept in position and rotated by the limiting effect of the limit ring 41. The moving plate 43 is fixedly connected to the outside of the rotating sleeve 42, and the moving plate 43 can be deflected. At the same time, the moving plate 43 drives the sliding sleeve 22 to move synchronously through the rotating sleeve 42 and the limit ring 41 when moving. The moving plate 43 passes through the outer protective shell 1, and a J-shaped slide groove 11 is provided on the outer protective shell 1, so that the moving plate 43 moves to the bottom position of the slide groove 11 and then rotates a certain angle to get the slide groove 11 stuck. The handle 44 is fixedly connected to one end of the moving plate 43 away from the rotating sleeve 42, and the handle 44 facilitates the movement of the moving plate 43. The connecting mechanism 4 also includes a second spring 45 sleeved on the outer ring of the sliding sleeve 22, and the second spring 45 is arranged between the synchronous plate 23 and the sliding plate 32. The two ends of the second spring 45 are respectively fixedly connected to the synchronous plate 23 and the sliding plate 32. The second spring 45 is used to release the elastic force after the metal tin at the soldering position melts and drives the sliding plate 32 to move downward, and at the same time drives the second conductive sheet 34 away from the first conductive sheet 27 to achieve disconnection.
[0033] In this embodiment, first, the handle 44 is held by hand and the handle 44 is pulled to drive the moving plate 43 to move. The moving plate 43 drives the sliding sleeve 22 to move synchronously through the rotating sleeve 42 and the limiting ring 41. When the moving plate 43 moves to the bottom position of the slide slot 11, the moving plate 43 is rotated so that the moving plate 43 is stuck in the slide slot 11. At the same time, the sliding sleeve 22 drives the synchronous plate 23 to move downward synchronously when moving downward, compressing the second spring 45. The sliding sleeve 22 drives the moving block 24 to move downward through the synchronous plate 23, so that the first conductive sheet 27 moves downward and approaches the second conductive sheet 34. When the first conductive sheet 27 contacts the second conductive sheet 34, the moving plate 43 has not yet moved to the bottom position of the slide slot 11. As the moving plate 43 continues to move downward, the moving block 24 continues to move downward, and the first conductive sheet 27 has been fixed in contact with the second conductive sheet 34, so that the first spring 28 is compressed, so that the first conductive sheet 27 is pressed against the second conductive sheet 34, and the circuit path is realized. When the circuit is short-circuited, the current passing through the fixing frame 31 and the sliding plate 32 increases, thereby increasing the temperature, causing the metal tin at the welding point between the fixing frame 31 and the sliding plate 32 to melt, so that the second spring 45 releases the elastic force to move the sliding plate 32 downward, and at the same time, the second conductive sheet 34 moves downward away from the first conductive sheet 27, and the circuit is automatically disconnected at this time, thereby improving the safety of the circuit system and ensuring the safety of electrical equipment and users.
[0034] The above specific embodiment is only an optional embodiment of the present invention.
