Description
Technical Field
[0001] This utility model relates to the field of relay technology, specifically to an intelligent disconnecting switch mechanism. Background Technology
[0002] A relay is an electromagnetic switch that uses a small current to control the switching on and off of a large current, achieving automatic circuit control and safety protection. In the prior art, invention patent application CN119480555A discloses a relay with a large opening distance switching mechanism. It includes a moving component and a stationary component disposed within a relay base. The moving component includes a moving electrode, and the stationary component includes a stationary electrode. One end face of the negative electrode is closely attached to one side face of the relay base, spaced apart from the positive electrode. The negative electrode and the positive electrode are arranged parallel to each other to fit the internal structure of the relay base, increasing space utilization and providing space to increase the opening distance of the switching mechanism. However, although this electromagnetic switch can significantly increase the opening distance, it is difficult to quickly confirm the current state during manual operation, easily increasing the risk of misjudgment or misoperation. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art where it is difficult to quickly confirm the current state during manual operation, which easily increases the risk of misjudgment or misoperation, thereby providing an intelligent disconnecting switch mechanism that can indicate the current state of the electromagnetic switch.
[0004] Therefore, this utility model provides an intelligent disconnecting switch mechanism, including a base, a cover plate covering the base, and a contact assembly disposed inside the base and the cover plate. The contact assembly includes a moving contact and a stationary contact capable of opening and closing. The moving contact has an open state that is separated from the stationary contact and a closed state that is in contact with the stationary contact. An indicator component capable of indicating the disconnecting switch status is disposed above the contact assembly, and the indicator component is linked with the moving contact.

[0007] Furthermore: the movable contact piece is provided with a lever that contacts the indicator, the indicator is provided with a contact rod that contacts the lever, the indicator has a first display part indicating that the movable contact is in the open state and a second display part indicating that the movable contact is in the closed state, and the base is provided with a clearance groove to avoid the first display part or the second display part. When the movable contact piece switches from the closed state to the open state, the lever can drive the contact rod to move, so that the first display part is located below the clearance groove.
[0008] Furthermore, the base is also equipped with a magnetic holding mechanism. The magnetic holding mechanism is connected to the extension by a first U-shaped rod, and the pressing rod is connected to the extension by a second U-shaped rod. There is a through groove between the base and the cover plate for the pressing rod to pass through. When the moving contact switches from the closed state to the open state, the pressing rod can move into the base and the cover plate along the setting direction of the through groove.
[0009] Furthermore, the indicator also has a display block arranged in a fan shape, with a plug connected to the display block. The base has a slot for inserting the plug, and a torsion spring is sleeved on the outside of the plug. The first display part and the second display part are both disposed on the display block, and the display block can rotate along the axis of the plug.
[0010] Furthermore, a guide slope is provided at the position where the contact rod contacts the paddle to guide the rotation of the display block.

[0026] Example
[0027] This embodiment provides an intelligent disconnecting switch mechanism, including a base 1, a cover plate 2 covering the base 1, and a contact assembly 3 disposed inside the base 1 and the cover plate 2. The contact assembly 3 includes a moving contact 31 and a stationary contact 32 capable of opening and closing. The moving contact 31 has an open state that is separated from the stationary contact 32 and a closed state that is in contact with the stationary contact 32. An indicator component 4 capable of indicating the disconnecting switch state is disposed above the contact assembly 3, and the indicator component 4 is linked with the moving contact 31.
[0028] The specific improvements mentioned above are as follows: Figures 1-3 As shown, a cover plate 2 is provided above the base 1. A stationary contact piece 32 and a moving contact piece 31 are provided inside the cover plate 2. Compared with the prior art, an indicator component 4 is provided between the stationary contact piece 32 and the moving contact piece 31. When the moving contact piece 31 and the stationary contact piece 32 switch from the open state to the closed state, or from the closed state to the open state, the indicator component 4 can make different changes according to the position change of the moving contact, so that the user can know whether the disconnecting switch is currently in the open state or the closed state according to the state of the indicator component 4.
[0029] Based on the above embodiments: a PCB board 5 is provided on the base 1, a micro switch 41 is provided on the PCB board 5, and an extension 12 that is linked with the micro switch 41 is provided on the moving contact 31.
[0030] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a PCB board 5 is provided on the base 1. The PCB board 5 has a micro switch 41 with an upward-curving extension piece. The moving contact 31 has an extension part 12. When the moving contact 31 switches from the closed state to the open state, the extension part 12 on the moving contact 31 will press the upward-curving extension piece on the micro switch 41 downward, thereby triggering the micro switch 41. The micro switch 41 controls the opening and closing of the circuit through the on and off state of its contacts, thereby converting the mechanical signal into an electrical signal and transmitting it to the outside. The information transmission between the PCB board 5 and other components is existing technology and will not be described here.
[0031] Based on the above embodiments: the indicator component 4 includes an indicator 42 for indicating the state of the disconnecting switch and a pressing rod 43 that can drive the moving contact to switch from the closed state to the open state.
[0032] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a positioning rod is provided at the middle position of the moving contact 31. The indicating component 4 includes an indicating element 42 and a pressing rod 43. When the moving contact 31 switches from the closed state to the open state, the moving contact 31 rotates along the axis of the positioning rod. The indicating element 42 can switch states as the moving contact 31 rotates, so that external operators can quickly understand the current state of the disconnecting switch. The pressing rod 43 is linked with the moving contact 31. When the pressing rod 43 is pressed down, it can drive the moving contact 31 to rotate away from the stationary contact 32, so that the moving contact 31 switches from the closed state to the open state. In this way, the disconnecting switch can be manually opened and closed.
[0033] Based on the above embodiments: the movable contact 31 is provided with a lever 6 that contacts the indicator 42, the indicator 42 is provided with a contact rod 44 that contacts the lever 6, the indicator 42 has a first display part 45 indicating that the movable contact is in the open state and a second display part 46 indicating that the movable contact is in the closed state, and the base 1 is provided with a clearance groove 13 to avoid the first display part 45 or the second display part 46. When the movable contact 31 switches from the closed state to the open state, the lever 6 can drive the contact rod 44 to move, so that the first display part 45 is located below the clearance groove 13.
[0034] The specific improvements mentioned above are as follows: Figures 2-5As shown, a lever 6 is provided on the movable contact piece 31, and a contact rod 44 is provided on the indicator 42. When the movable contact piece 31 and the stationary contact piece 32 are separated, the lever 6 on the movable contact piece 31 will rotate clockwise with the movable contact piece 31, and the lever 6 will drive the contact rod 44 to rotate counterclockwise, thereby causing the first display part 45 to rotate to the lower part of the clearance groove 13, and vice versa, the second display part 46 will be located below the clearance groove 13.
[0035] Based on the above embodiments: the base 1 is further provided with a magnetic holding mechanism 11. The magnetic holding mechanism 11 is connected to the extension 12 by a first U-shaped rod 7. The pressing rod 43 is connected to the extension 12 by a second U-shaped rod 71. There is a through groove 72 between the base 1 and the cover plate 2 for the pressing rod 43 to pass through. When the moving contact 31 switches from the closed state to the open state, the pressing rod 43 can move inward along the setting direction of the through groove 72 into the base 1 and the cover plate 2.
[0036] The specific improvements mentioned above are as follows: Figure 3 As shown, the magnetic holding mechanism 11 and the extension 12 are connected by a first U-shaped rod 7, and the pressing rod 43 and the extension 12 are connected by a second U-shaped rod 71. The lower end of the pressing rod 43 passes through the through groove 72. When the operator presses the pressing rod 43, the pressing rod 43 can move downward along the through groove 72. At the same time, due to the connection of the first U-shaped rod 7 and the second U-shaped rod 71, the pressing rod 43 can drive the moving contact 31 to rotate, thereby switching the moving contact 31 from the closed state to the open state.
[0037] Based on the above embodiments: the indicator 42 is further provided with a display block 8 in a fan-shaped structure, the display block 8 is connected to a plug rod 81, the base 1 is provided with a slot for the plug rod 81 to be inserted, the plug rod 81 is sleeved with a torsion spring 73, the first display part 45 and the second display part 46 are both provided on the display block 8, and the display block 8 can rotate along the axis of the plug rod 81.
[0038] Based on the above embodiments: a guide slope 9 is provided at the position where the contact rod 44 contacts the beater 6 to guide the rotation of the display block 8.
[0039] The specific improvements mentioned above are as follows: Figure 4 As shown, a display block 8 is provided on the indicator 42, and a plug rod 81 is connected to the display block 8. During use, the position of the first display part 45 and the second display part 46 below the clearance groove 13 is switched by rotating the display block 8, so that the operator can quickly understand whether the disconnecting switch is currently in the open or closed state. The guide slope 9 can play a good guiding role when the flap 6 contacts the contact rod 44, so that the display block 8 can rotate normally.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
