Description
Technical Field
[0001] The utility model relates to the technical field of plugs, in particular to an operating mechanism of a plug with an integrated circuit breaker function. Background Art
[0002] The connectors of general electronic products and the plugs of electrical appliances are called plugs. Household AC power plugs and sockets have a male connector with a rod or copper plate protrusion, which is physically inserted into a female power socket with a slot or hole.
[0003] Existing plugs usually do not have a leakage protection function, which makes it very dangerous when leakage occurs in the plug. Utility Model Content
[0004] In summary, in order to overcome the deficiencies of the prior art, the utility model provides an operating mechanism of a plug with an integrated circuit breaker function.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an operating mechanism of a plug with integrated circuit breaker function, comprising an electromagnet, a movable part, a switch button and a moving contact piece, wherein the moving contact piece is located in the plug, the switch button is arranged to pass through the top cover of the plug, the moving contact piece is arranged to fit with the plug pin when the switch button is pressed, the switch button drives the movable part to separate the moving contact piece and the plug pin when it pops up, and the electromagnet controls the switch button to pop out when it is energized.
[0006] With such a configuration, when in use, the switch button can be pressed, and the switch button will drive the movable part to control the moving contact piece to contact with the pin of the plug. The other end of the moving contact piece is directly connected to the wire or connected to the circuit board. At this time, the plug is in a connected state. When leakage occurs when the plug is in use, the electromagnet will be energized to generate magnetism, and then the output head of the electromagnet will be sucked back by the magnetic force. During the suction process, the switch button will pop out. When the switch button pops out, it will drive the movable part to separate the moving contact piece and the pin of the plug, thereby disconnecting the connection state of the pin, achieving the circuit-breaking effect of the plug, which is safer.
[0007] Furthermore, the movable contact piece is provided with an elastic piece, and the contact of the movable contact piece is located on the elastic piece. When the movable member moves, it drives the elastic piece to move back and forth in the direction of the plug pin of the plug.
[0008] With this arrangement, the movable part only needs to push the elastic sheet toward the pin of the plug when moving. For example, when the switch button is pressed, the elastic sheet is pushed and the two are in contact. When the switch button pops up, the movable part withdraws. In this way, the elastic sheet will be separated from the pin of the plug under the action of its own elastic force, which is more stable.
[0009] Furthermore, the movable part is provided with a spring slot adapted thereto at a position corresponding to the elastic sheet, and the position where the elastic sheet is provided with the contact is bent toward the base of the plug, and when the switch button is activated, the movable part is controlled to slide back and forth toward the movable contact sheet.
[0010] With such arrangement, after the elastic sheet is bent, when the movable part moves away from the elastic sheet, the elastic sheet will be pushed up to fit the plug pins. Otherwise, the elastic force will decrease. The structure is simple and the operation is convenient. Moreover, the elastic sheet will slide in the spring sheet slot and is more stable.
[0011] Furthermore, it also includes a driving member, which is linked to the output head of the electromagnet, and the side of the driving member facing the movable member is provided with an insertion block that penetrates the movable member, and the switch button is provided with a limiting groove adapted to the position of the insertion block when the switch button is pressed, and the switch button is provided with a reset member, which applies a force to the switch button to pop it out.
[0012] With such arrangement, the driving member will be extended and retracted together with the output head of the electromagnet, and the plug block will penetrate the movable member and slide on the movable member. At the same time, the spring of the electromagnet will push the driving member against the movable member, indirectly applying a force against the elastic sheet to the movable member. When the switch button of the driving member is pressed, the limit slot reaches the position of the plug block, and the plug block will be inserted into the limit slot, limiting the position of the switch button to the pressed state. At the same time, since the plug block is inserted into the limit slot, the driving member moves to the farthest movable position, and the movable member will also be pushed to the end of the elastic sheet, pushing it to the highest position, triggering the connected state. When leakage occurs, the plug block will be pulled out, the switch button will be released, the reset member will be ejected, and the movable member will also be pushed by the elastic force of the elastic sheet and will be unable to continue to maintain the connected state. In this way, the line is disconnected and the structure is stable.
[0013] Furthermore, the movable part is provided with a first clearance groove adapted to the switch button at a position corresponding to the switch button, and the insert block is provided with a second clearance groove adapted to the switch button at a position corresponding to the switch button.
[0014] With such arrangement, the switch button will move in the first make way slot and the second make way slot, thus saving more space and making the plug smaller in size.
[0015] Furthermore, a connection groove is provided at a position where the movable part is penetrated by the insert block, and outwardly disposed connection claws are provided on both sides of the insert block.
[0016] With such arrangement, the second clearance groove can provide deformation space for the side panels on both sides, and the sides can bend inward, so that the plug-in block with connecting claws can be easily inserted during installation. If leakage occurs after insertion, the claw will hit the bottom of the connecting groove after the driving part is pulled back, and move the movable part toward the elastic sheet, thereby loosening the elastic sheet. The structure is more stable without relying solely on the elastic force of the elastic sheet.
[0017] Furthermore, a driving groove is provided on the top surface of the driving member, an opening groove is provided on the side of the driving groove facing the electromagnet, a positioning plate adapted to the driving groove is provided at the position of the output head of the electromagnet, and the width of the opening groove is larger than the outer diameter of the output rod of the electromagnet and smaller than the outer diameter of the positioning plate.
[0018] With this arrangement, the output rod of the electromagnet will be in a shape similar to a nail. During installation, the positioning disk at the output head position can be aligned with the drive slot and inserted. After insertion, the output rod will fall into the open slot. Later, when the electromagnet is energized to pull the output rod back, the positioning disk will drive the entire drive component to move together in the drive slot. The structure is simple and easy to disassemble and assemble.
[0019] Furthermore, a T-shaped block is provided on the top of the movable part corresponding to the position of the elastic sheet, the spring sheet slots are located on both sides of the T-shaped block, and the elastic sheet is provided with a positioning groove adapted to the vertical rod position of the T-shaped block.
[0020] With such arrangement, the end of the elastic sheet will be inserted into the two sides of the T-shaped block of the movable part in a fork-like manner and move, which is more stable and not easy to loosen.
[0021] Furthermore, the spring piece slot is in a flared shape, and the height of one side of the spring piece slot facing the elastic sheet is smaller than that of the other side.
[0022] With such arrangement, the elastic sheet will not push against the upper and lower surfaces thereof when moving in the elastic sheet slot, thereby causing excessive deformation of the elastic sheet.
[0023] Furthermore, the bottom of the switch button is chamfered at a side facing the insert block.
[0024] With this arrangement, when the switch button is pressed, the chamfer at the bottom will first press on the insert, and then push the insert back a little until it moves to the position of the limit slot and pops out, making it easier to press and without getting stuck.

DETAILED DESCRIPTION

After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of this embodiment, they are protected by patent law.
[0034] Referring to the accompanying drawings, the utility model provides the following technical solutions: an operating mechanism of a plug with an integrated circuit breaker function, comprising an electromagnet 4, a movable part 5, a switch button 6 and a moving contact piece 301, wherein the moving contact piece 301 is located in the plug, and the switch button 6 is arranged to penetrate the top cover 1 of the plug, and when the switch button 6 is pressed, the moving contact piece 301 is arranged to fit with the plug pin 2 of the plug, and when the switch button 6 pops up, it drives the movable part 5 to separate the moving contact piece 301 and the plug pin 2, and when the electromagnet 4 is energized, it controls the switch button 6 to pop up. The above setting is not limited, and a circuit board can also be arranged in the plug to connect the circuit, and a test button is set to control the power on.
[0035] With such arrangement, when in use, the switch button 6 can be pressed, and the switch button 6 will drive the movable part 5 to control the moving contact piece 301 to contact the pin 2 of the plug. The other end of the moving contact piece 301 is directly connected to the wire or connected to the circuit board. At this time, the plug is in a connected state. When leakage occurs during use of the plug, the electromagnet 4 will be energized to generate magnetism, and then the output head of the electromagnet 4 will be sucked back by the magnetic force. During the suction process, the switch button 6 will pop out. When the switch button 6 pops out, it will drive the movable part 5 to separate the moving contact piece 301 and the pin 2 of the plug, thereby disconnecting the connection state of the pin 2, achieving the circuit-breaking effect of the plug, which is safer.
[0036] Preferably, in this embodiment, the movable contact piece 301 is provided with an elastic piece 3011 , and the contact of the movable contact piece 301 is located on the elastic piece 3011 . When the movable member 5 moves, it drives the elastic piece 3011 to move back and forth toward the pin 2 of the plug.
[0037] With such arrangement, the movable part 5 only needs to push the elastic sheet 3011 toward the pin 2 of the plug when moving. For example, when the switch button 6 is pressed, the elastic sheet 3011 is pushed and the two are in contact. When the switch button 6 pops up, the movable part 5 withdraws. In this way, the elastic sheet 3011 will be separated from the pin 2 of the plug under the action of its own elastic force, which is more stable.
[0038] In this embodiment, the movable part 5 is preferably provided with a spring slot 501 adapted thereto at a position corresponding to the elastic sheet 3011, and the position at which the contact is provided on the elastic sheet 3011 is bent toward the base 3 of the plug, and when the switch button 6 is activated, the movable part 5 is controlled to slide back and forth toward the movable contact sheet 301.
[0039] With such arrangement, after the elastic sheet 3011 is bent, when the movable part 5 moves away from the elastic sheet 3011, the elastic sheet 3011 will be pushed up to fit the plug pin 2 of the plug, otherwise the elastic force will decrease. The structure is simple and the operation is convenient, and the elastic sheet 3011 will slide in the spring sheet slot 501, which is more stable.
[0040] Preferably, the present embodiment further comprises a driving member 7, wherein the driving member 7 is arranged in linkage with the output head of the electromagnet 4, and the side of the driving member 7 facing the movable member 5 is provided with an insert block 701 which passes through the movable member 5, and the switch button 6 is provided with a limiting groove 601 which is adapted to the position of the insert block 701 when the switch button 6 is pressed, and the switch button 6 is provided with a reset member 602, and the reset member 602 applies a force to the switch button 6 to pop it out, and the above setting is not limiting, and the reset member 602 can be a pressure spring arranged between the switch button 6 and the base 3 of the plug, and positioning columns can also be arranged above and below the pressure spring.
[0041] With such arrangement, the driving member 7 will be extended and retracted together with the output head of the electromagnet 4, and the plug block 701 will penetrate the movable member 5 and slide on the movable member 5. At the same time, the spring of the electromagnet 4 will push the driving member 7 against the movable member 5, indirectly applying a force to the movable member 5 against the elastic sheet 3011. When the switch button 6 is pressed, the limiting groove 601 of the driving member 7 reaches the position of the plug block 701, and the plug block 701 will be inserted into the limiting groove 601, limiting the position of the switch button 6 in the pressed state. At the same time, since the plug block 701 is inserted into the limiting groove 601, the driving member 7 moves to the farthest movable position, and the movable member 5 will also be pushed to the end of the elastic sheet 3011, pushing it to the highest point, triggering the connected state. When leakage occurs, the plug block 701 will be pulled out, the switch button 6 is released from the limit, and the reset member 602 will be ejected. The movable member 5 will also be pushed by the elastic force of the elastic sheet 3011 and cannot continue to maintain the connected state, thus disconnecting the line and stabilizing the structure.
[0042] Preferably, in this embodiment, the movable member 5 is provided with a first clearance groove 502 adapted thereto at a position corresponding to the switch button 6 , and the plug block 701 is provided with a second clearance groove 7011 adapted thereto at a position corresponding to the switch button 6 .
[0043] With such arrangement, the switch button 6 will move in the first make way slot 502 and the second make way slot 7011, thus saving more space and making the plug smaller in size.

[0045] With such arrangement, the second clearance groove 7011 can provide deformation space for the side panels on both sides, and the sides can bend inward, so that the plug 701 with the connecting claw 7012 can be easily inserted during installation. If leakage occurs after insertion, the claw will hit the bottom of the connecting groove 503 after the driving part 7 is pulled back, and move the movable part 5 toward the elastic sheet 3011, thereby loosening the elastic sheet 3011. The structure is more stable without relying solely on the elastic force of the elastic sheet 3011.

During installation, the positioning disk 401 at the output head position can be aligned with the driving groove 702 and inserted. After insertion, the output rod will fall into the opening groove 703. Later, when the electromagnet 4 is energized to pull the output rod back, the positioning disk 401 will drive the entire driving member 7 to move together in the driving groove 702.
