[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0039] Please refer to the attached document. Figures 1-6 This application provides a button overload switch 100, which achieves the detection and protection of current in the circuit through the synergistic effect of thermal protection principle and electromagnetic trigger.
[0040] Please refer to the attached document. Figures 1-6In this embodiment, the button overload switch 100 includes a switch base 10, a first conductive sheet 20, a second conductive sheet 30, and a button 40. The switch base 10 is provided with a first guide arm 11. The first conductive sheet 20 passes through the switch base 10 and is used to connect conductive wires. The second conductive sheet 30 passes through the switch base 10 and is used to connect conductive wires. The second conductive sheet 30 and the first conductive sheet 20 are positive and negative electrodes, respectively. The button 40 is retractably connected to the switch base 10. When the button 40 is retracted, it conducts electricity between the second conductive sheet 30 and the first conductive sheet 20. 0; The button 40 integrates a second guide arm 41, which is located on the periphery of the button 40. The second guide arm 41 is guided and connected to the first guide arm 11, so that the first guide arm 11 restricts the movement direction of the second guide arm 41. This allows the button 40 to extend and retract relative to the switch base 10 through the cooperation of the second guide arm 41 and the first guide arm 11, preventing the button 40 from shifting relative to the switch base 10 during extension and retraction, and improving the extension and retraction effect of the button 40 in the button overload switch 100. At the same time, the integrated design of the button 40 and the second guide arm 41 makes full use of space and improves the extension and retraction stability of the button 40 in the button overload switch 100.
[0041] Please refer to the attached document. Figures 1-6 In this embodiment, the switch base 10 serves as a support component for the button overload switch 100, and is used to support the first conductive sheet 20, the second conductive sheet 30, and the button 40. The switch base 10 is provided with a first guide arm 11; the first guide arm 11 is located on the periphery of the switch base 10 and is arranged in a vertical direction.
[0042] The first conductive piece 20 passes through the switch base 10 and is used to connect the conductive wire; the second conductive piece 30 passes through the switch base 10 and is used to connect the conductive wire; the second conductive piece 30 and the first conductive piece 20 are positive and negative poles respectively; so that the button overload switch 100 can be electrically connected to the equipment through the cooperation of the first conductive piece 20 and the second conductive piece 30.
[0043] Button 40 is located on the upper side of switch base 10 and is retractably connected to switch base 10 to facilitate adjustment of button 40's position relative to switch base 10. In the retracted state, button 40 conducts electricity between the second conductive sheet 30 and the first conductive sheet 20. Button 40 has an integrally integrated second guide arm 41, which is located on the periphery of button 40 and is guided and connected to the first guide arm 11. The first guide arm 11 restricts the movement direction of the second guide arm 41, allowing button 40 to retract and extend relative to switch base 10 through the cooperation of the second and first guide arms 41. This prevents button 40 from shifting relative to switch base 10 during retraction and extension, improving the retraction effect of button 40 in the button overload switch 100. Simultaneously, the integrated design of button 40 and the second guide arm 41 fully utilizes space and improves the retraction stability of button 40 in the button overload switch 100.
[0044] Please refer to the attached document. Figures 1-4 In this embodiment, the second guide arm 41 is provided with a first guide hole 41a, which extends vertically and is adapted to the first guide arm 11, allowing the first guide arm 11 to pass through. This allows the inner wall of the first guide hole 41a to restrict the movement direction of the first guide arm 11, ensuring that the first guide arm 11 can move relative to the extension direction of the first guide hole 41a. This facilitates the second guide arm 41's extension and retraction relative to the first guide arm 11 through the first guide hole 41a. Optionally, the first guide hole 41a is an M-shaped hole, with its inner contour matching the outer contour of the first guide arm 11, and the inner contour of the first guide hole 41a having a clearance fit with the outer contour of the first guide arm 11.
[0045] Please refer to the attached document. Figures 1-4 In this embodiment, the switch base 10 is provided with a third guide arm 12; the button 40 is integrally integrated with a fourth guide arm 42. By integrating the button 40 with the fourth guide arm 42, the space of the button 40 is fully utilized. The fourth guide arm 42 is guided and connected to the third guide arm 12 so that the fourth guide arm 42 can extend and retract under the guidance of the third guide arm 12, ensuring the reset effect of the fourth guide arm 42. At the same time, it improves the smoothness of the extension and retraction of the button 40 relative to the switch base 10. By arranging the fourth guide arm 42 and the third guide arm 12 to strengthen the guiding effect of the button 40 relative to the switch base 10, the button 40 is prevented from shifting relative to the switch base 10 during the extension and retraction process, further improving the extension and retraction effect and reset effect of the button 40 of the button overload switch 100.
[0046] Please refer to the attached document. Figures 1-4In this embodiment, the fourth guide arm 42 and the second guide arm 41 are distributed at different positions of the button 40 and arranged around the button 40, so that the fourth guide arm 42 and the second guide arm 41 can make full use of the peripheral space of the button 40.
[0047] Please refer to the attached document. Figures 1-4 In this embodiment, the third guide arm 12 is provided with a second guide hole 12a, which is adapted to the fourth guide arm 42 and allows the fourth guide arm 42 to pass through. This allows the inner wall of the second guide hole 12a to restrict the movement direction of the fourth guide arm 42, thereby facilitating the third guide arm 12 to extend and retract relative to the fourth guide arm 42 through the second guide hole 12a. Optionally, the second guide hole 12a is a square hole, and the inner contour of the second guide hole 12a is adapted to the outer contour of the fourth guide arm 42. The inner contour of the second guide hole 12a and the outer contour of the fourth guide arm 42 are in clearance fit.
[0048] Please refer to the attached document. Figures 1-4 In this embodiment, the button overload switch 100 further includes a first elastic element 50. The button 40 is provided with a movable post 43, which is arranged vertically and movably passes through the switch base 10 to facilitate adjustment of the position of the movable post 43 relative to the switch base 10. The first elastic element 50 is sleeved on the movable post 43 and elastically contacts the button 40 and the switch base 10, so that the first elastic element 50 applies an elastic force to the button 40, thereby facilitating the elastic extension and retraction of the button 40 relative to the switch base 10.
[0049] Please refer to the attached document. Figures 1-5 In this embodiment, the switch base 10 has a built-in engagement post 13, which is arranged opposite to the moving post 43. The top of the engagement post 13 engages with the bottom of the moving post 43 to limit the offset of the moving post 43, so that the button 40 can drive the moving post 43 to engage with the engagement post 13. This allows the switch base 10 to limit the offset of the button 40 through the cooperation of the moving post 43 and the engagement post 13, thus ensuring the positional accuracy of the button 40 relative to the switch base 10.
[0050] Please refer to the attached document. Figures 1-3 A second elastic element 14 is provided between the switch base 10 and the engagement post 13. The second elastic element 14 elastically contacts the switch base 10 and the engagement post 13 so that the second elastic element 14 can apply an elastic force to the engagement post 13, thereby facilitating the elastic extension and contraction of the engagement post 13 relative to the switch base 10.
[0051] Please refer to the attached document. Figures 1-3In embodiment 6 of this application, the button overload switch 100 is provided with an overload protection piece 60. The overload protection piece 60 is built into the switch base 10 and is located between the first conductive piece 20 and the second conductive piece 30, so that the overload protection piece 60 can be fixed to the inner side of the switch base 10, thereby facilitating the arrangement of the overload protection piece 60 relative to the first conductive piece 20 and the second conductive piece 30 to achieve overload protection.
[0052] Please refer to the attached document. Figures 1-3 In embodiment 6 of this application, the overload protection piece 60 contacts the first conductive piece 20 and the second conductive piece 30 in its natural state, so that the first conductive piece 20 and the second conductive piece 30 are in a conductive state; thereby ensuring that the circuit of the device is in a safe state. When the button overload switch 100 is in an overload state, the overload protection piece 60 disengages from the second conductive piece 30, so that the first conductive piece 20 and the second conductive piece 30 are in a disconnected state, thereby achieving overload protection for the first conductive piece 20 and the second conductive piece 30 through the overload protection piece 60.
[0053] Please refer to the attached document. Figure 6 The overload protection plate 60 includes a first connecting portion 61 and a second connecting portion 62. The first connecting portion 61 is electrically connected to the first conductive plate 20, and the second connecting portion 62 is connected to the first connecting portion 61 and is movable relative to the first connecting portion 61 in an overload state. The second connecting portion 62 is in contact with the second conductive plate 30 in a natural state, or the second connecting portion 62 is detached from the second conductive plate 30 in an overload state. Overload protection is achieved by the overload protection plate 60 detaching the second conductive plate 30 in an overload state. Optionally, the overload state is when the current value exceeds a preset rated current value, and the second connecting portion 62 generates more heat due to the excessive current in the overload state.
