Description

Technical Field

[0001] The utility model relates to the technical field of plugs, and specifically, to a plug integrating a circuit breaker function. Background Art

[0002] The connector of general electronic products and the pin of electrical appliances are called plugs. The household AC power socket and socket have a male connector protruding in a rod shape or a copper plate shape, which is physically inserted into a female connector type power socket with a slot or a cavity.

[0003] Existing plugs usually do not have the function of leakage protection, which is rather dangerous when leakage occurs in the plugs. Content of the Utility Model

[0004] In summary, to overcome the deficiencies of the prior art, the utility model provides a plug integrating a circuit breaker function, which can play a protective role when leakage occurs.

[0005] To achieve the above object, the utility model provides the following technical solution: A plug integrating a circuit breaker function, including a top cover, pins and a base. There are at least two pins, and the pins penetrate through the base and are connected to it. It also includes an electromagnet, a movable part and a switch button. The switch button penetrates through the top cover. A static contact is arranged at the position of the pin inside the base, and a movable contact is arranged at the position corresponding to the static contact inside the base. When the switch button is pressed, the movable contact is arranged in contact with the static contact. When the switch button pops up, it drives the movable part to separate the movable contact from the static contact, and when the electromagnet is energized, it controls the switch button to pop up.

[0006] With such a setting, when in use, the switch button can be pressed. The switch button will drive the movable part to control the movable contact and the static contact to contact. The other end of the movable contact 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 the use of the plug, the electromagnet will be energized to generate magnetism. Then the output head of the electromagnet will be sucked back by the magnetic force. During the sucking-back process, the switch button pops up. When the switch button pops up, it will drive the movable part to separate the movable contact from the static contact, thus disconnecting the connection state of the pin and achieving the open-circuit effect of the plug, which is safer.

[0007] Further, the movable contact is provided with an elastic sheet, the contact head of the movable contact is located on the elastic sheet, and when the movable part moves, it drives the elastic sheet to reciprocate in the direction of the static contact.

[0008] With such a setting, the movable part only needs to push the elastic sheet towards the static contact when moving. For example, when the switch button is pressed, the elastic sheet is pushed to make the contacts of the two contacts touch. When the switch button pops up, the movable part withdraws. In this way, the elastic sheet will separate from the static contact under the action of its own elastic force, which is more stable.

[0009] Furthermore, the movable part is provided with a spring slot adapted to the elastic sheet 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, and when the switch button is activated, the movable part is controlled to slide back and forth toward the movable contact sheet.

[0010] With this 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 static contact sheet. Otherwise, the elastic force will decrease. The structure is simple and the operation is convenient. In addition, 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 reset member is a pressure spring arranged between the switch button and the base.

[0014] With such arrangement, when the switch button is pressed, the pressure spring is compressed, and when leakage occurs, the pressure spring releases its elastic force to eject the switch button, and the structure is simple.

[0015] 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.

[0016] 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.

[0017] Further, a connection groove is provided at the position where the movable member is penetrated by the insertion block, and connection claws are respectively provided on both sides of the insertion block and are arranged outward.

[0018] With such a setting, the second relief groove can provide a deformation space for the side plates on both sides, and the sides can be bent inward. In this way, when installing, the insertion block provided with the connection claws can be easily inserted. After insertion, when the leakage occurs, after the driving member is pulled back, the claws will still top against the bottom of the connection groove, driving the movable member to move towards the elastic sheet, thereby loosening the elastic sheet. It does not only rely on the elasticity of the elastic sheet, and the structure is more stable.

[0019] Further, a T-shaped block is provided at the top of the movable member corresponding to the position of the elastic sheet. The elastic 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 a setting, the end of the elastic sheet will be inserted and move on both sides of the T-shaped block of the movable member in a shape similar to a fork, which is more stable and not easy to loosen.

[0021] Further, the bottom of the switch button is provided with an inclined chamfer on the side facing the insertion block.

[0022] With such a setting, when the switch button is pressed, the chamfer at its bottom will first press against the insertion block, and then push the insertion block back a little until it moves to the position of the limit groove and pops out. It is easier to press and will not get stuck.

[0023] Further, the base is provided with a sliding groove adapted to the movable member.

[0024] With such a setting, the movable member is more stable when installed and slides in the sliding groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] This specific embodiment is only an explanation of this embodiment, and it is not a limitation of this embodiment. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of this embodiment, they are protected by the patent law.

[0032] Referring to the attached drawings, the present invention provides the following technical solution: A plug integrated with a circuit breaker function includes a top cover 1, pins 2 and a base 3. There are at least two pins 2, and the pins 2 penetrate through the base 3 and are connected thereto. It also includes an electromagnet 4, a movable part 5 and a switch button 6. The switch button 6 penetrates through the top cover 1. A static contact piece 201 is provided at the position of the pin 2 inside the base 3, and a moving contact piece 301 is provided at the position corresponding to the static contact piece 201 inside the base 3. When the switch button 6 is pressed, the moving contact piece 301 is in contact with the static contact piece 201. When the switch button 6 pops up, it drives the movable part 5 to separate the moving contact piece 301 from the static contact piece 201. When the electromagnet 4 is energized, it controls the switch button 6 to pop up. The above setting is not a limitation. A circuit board can also be provided inside the plug to connect the circuits, and then a test button can be set to control the power on.

[0033] With such a setting, when in use, the switch button 6 can be pressed, and the switch button 6 will drive the movable part 5 to control the contact between the moving contact piece 301 and the static contact piece 201. 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 a leakage occurs during the use of the plug, the electromagnet 4 will be energized to generate magnetism, and then the output head of the electromagnet 4 will be attracted back by the magnetic force. During the process of being attracted back, the switch button 6 pops up. When the switch button 6 pops up, it will drive the movable part 5 to separate the moving contact piece 301 from the static contact piece 201, thereby disconnecting the connection state of the pin 2 and achieving the open circuit effect of the plug, which is safer.

[0034] Preferably in this embodiment, the moving contact piece 301 is provided with an elastic piece 3011. The contact head of the moving contact piece 301 is located on the elastic piece 3011. When the movable part 5 moves, it drives the elastic piece 3011 to reciprocate in the direction of the static contact piece 201.

[0035] With such arrangement, the movable part 5 only needs to push the elastic sheet 3011 toward the static contact sheet 201 when moving. For example, when the switch button 6 is pressed, the elastic sheet 3011 is pushed to make the contact points of the two contact sheets touch. When the switch button 6 pops up, the movable part 5 withdraws. In this way, the elastic sheet 3011 will be separated from the static contact sheet 201 under the action of its own elastic force, which is more stable.

[0036] Preferably in this embodiment, the movable part 5 is 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, 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.

[0037] 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 static contact sheet 201. Otherwise, the elastic force will decrease. The structure is simple and the operation is convenient. Moreover, the elastic sheet 3011 will slide in the spring sheet slot 501 and is more stable.

[0038] 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 limit groove 601 which is adapted to the position of the insert block 701 when the switch button 6 is in a pressed state, 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 eject it, and the above setting is not limiting, and the driving member 7 and the output head of the electromagnet 4 can be directly fixedly connected, or can be plugged in with a U-shaped groove and a T-head.

[0039] 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.

[0040] Preferably in this embodiment, the reset member 602 is a compression spring disposed between the switch button 6 and the base 3. The above setting is not a limitation, and positioning posts can also be provided above and below the compression spring.

[0041] With such a setting, when the switch button 6 is pressed, the compression spring is compressed, and when there is a leakage, the elastic force released by the compression spring will pop up the switch button 6, with a simple structure.

[0042] Preferably in this embodiment, the movable member 5 is provided with a first relief groove 502 adapted to the switch button 6 at a position corresponding to the switch button 6, and the insertion block 701 is provided with a second relief groove 7011 adapted to the switch button 6 at a position corresponding to the switch button 6.

[0043] With such a setting, the switch button 6 will move in the first relief groove 502 and the second relief groove 7011, saving more space and making the plug smaller in volume.

[0044] Preferably in this embodiment, the movable member 5 is provided with a connection groove 503 at a position penetrated by the insertion block 701, and connection claws 7012 are respectively provided on both sides of the insertion block 701 and extend outward.

[0045] With such a setting, the second relief groove 7011 can provide a deformation space for the side plates on both sides, and the side edges can be bent inward. In this way, when installing, the insertion block 701 provided with the connection claws 7012 can be easily inserted. After insertion, when a leakage occurs, after the driving member 7 is pulled back, the claws will still top against the bottom of the connection groove 503 and drive the movable member 5 to move toward the elastic piece 3011, thereby releasing the elastic piece 3011. It does not only rely on the elastic force of the elastic piece 3011, and the structure is more stable.

[0046] Preferably in this embodiment, the top of the movable member 5 at a position corresponding to the elastic piece 3011 is provided with a T-shaped block 504, the elastic piece slots 501 are located on both sides of the T-shaped block 504, and the elastic piece 3011 is provided with a positioning groove 30111 adapted to the vertical rod position of the T-shaped block 504.

[0047] With such a setting, the end of the elastic piece 3011 will be inserted and move on both sides of the T-shaped block 504 of the movable member 5 in a shape similar to a fork, which is more stable and not easily loosened.

[0048] Preferably in this embodiment, the bottom of the switch button 6 is provided with an inclined chamfer on the side facing the insertion block 701.

[0049] With such a setting, when the elastic piece 3011 moves in the elastic piece slot 501, it will not top against its upper and lower surfaces and cause excessive deformation of itself.

[0050] Preferably in this embodiment, the base 3 is provided with a sliding groove 302 adapted to the movable member 5.

[0051] With such a setting, the movable member 5 is more stable when installed and slides in the sliding groove 302.
