Description

Technical Field

[0001] This utility model relates to the field of plug-in structure technology, and in particular to a linkage power supply mechanism and power output device. Background Technology

[0002] Most electrical appliances today connect to power via plugs and sockets for easy switching. Traditional sockets become energized as soon as they are connected to an external power source. To address this, some sockets incorporate sealing mechanisms, such as safety shutters, to prevent accidental insertion of external plugs or pins. However, while these safety shutters effectively block the socket, they don't completely prevent conductive objects from entering the socket. The safety shutters can still be forcibly opened, resulting in poor safety. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a linkage power extraction mechanism, which can prevent short circuits when external conductors accidentally enter the plug-in structure, thereby improving the safety of the plug-in structure.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A linkage power extraction mechanism includes a plug compartment, wherein a live wire compartment, a neutral wire compartment, and a ground wire compartment are provided inside the plug compartment, and each of the live wire compartment, the neutral wire compartment, and the ground wire compartment is provided with a pin. A live wire piece, a neutral wire piece, and a ground wire piece are provided on the plug compartment, and the live wire piece, the neutral wire piece, and the ground wire piece are respectively connected to the pins in the live wire compartment, the neutral wire compartment, and the ground wire compartment. The live wire piece and the neutral wire piece each include a first overlapping part and a second overlapping part, and the first overlapping part and the second overlapping part are normally open.

[0005] The linkage power supply mechanism also includes a movable power supply component, which is movably connected to the insertion compartment. The movable power supply component can push the first overlapping part so that the first overlapping part is electrically connected to the second overlapping part. When the movable power supply component retracts, the first overlapping part can disconnect from the second overlapping part.

[0006] In some possible implementations, the linkage power-taking mechanism further includes a reset member for retracting the movable power-taking component, and / or for disconnecting the first overlapping portion from the second overlapping portion.

[0007] In some possible implementations, the first overlapping portion is an elastic structure. When the movable power-collecting component pushes the first overlapping portion, the first overlapping portion can undergo elastic deformation and become electrically connected to the second overlapping portion. After the movable power-collecting component retracts, the first overlapping portion can disconnect from the second overlapping portion under the action of elastic restoring force.

[0008] In some possible implementations, the reset element is a spring, one end of which is connected to the movable power-taking assembly and the other end of which is connected to the pod or external mounting base.

[0009] In some possible implementations, the movable power-gathering assembly includes a sliding seat and a pressing head connected to the sliding seat. The sliding seat is slidably mounted within the insertion compartment. The sliding seat is provided with a guide ramp, and one end of the sliding seat with the guide ramp is simultaneously inserted into the neutral wire compartment and the ground wire compartment. When an electrical plug is inserted into the neutral wire compartment and / or the ground wire compartment and engages with the corresponding pin, the external electrical plug can abut against the guide ramp and push against the sliding seat, so that the sliding seat drives the pressing head to push towards the first overlapping portion.

[0010] In some possible implementations, the pod is provided with a movable hole, into which a resilient cap is installed, and the pressure head is movably inserted into the resilient cap and extends out of the pod from the resilient cap.

[0011] In some possible implementations, the periphery of the movable hole is provided with a mounting ring groove, and the outer periphery of the elastic cover is provided with a snap-fit ​​edge, which is snapped and fixed in the mounting ring groove.

[0012] In some possible implementations, the linkage power supply mechanism further includes a guide seat, into which the pressure head is movably inserted.

[0013] This utility model also provides a power output device, including a housing, an isolation frame, a protective door mechanism, and the aforementioned linkage power extraction mechanism. The plug compartment is installed inside the housing, and the plug compartment is provided with plug holes corresponding to the positions of all plug pins. The housing is provided with holes that mate with the plug holes. The isolation frame is installed in the area between the plug compartment and the housing. The isolation frame and the inner wall of the housing together form a protective chamber. The protective door mechanism is installed inside the protective chamber. The isolation frame is provided with through holes that mate with all the plug holes.

[0014] In some possible implementations, the protective door mechanism includes a movable plate with ramp holes adapted to the holes and insertion holes, the movable plate being repositionable within the protective chamber.

[0015] Compared to existing technologies, the advantages of this invention are as follows: The linkage power extraction mechanism and power output device of this invention are designed with a live wire compartment, a neutral wire compartment, and a ground wire compartment within the insertion chamber, ensuring safety within the insertion chamber and preventing short circuits after water ingress. Both the live wire and neutral wire pieces include a first and a second contact portion, both of which are normally open. This ensures the entire insertion chamber is de-energized when not in use, preventing short circuits even if an external conductor enters, thus improving the safety of the insertion structure. The designed movable power extraction component can push the first contact portion when in use, electrically connecting it to the second contact portion to form a conductive path. When not in use, the component can retract, disconnecting the first and second contact portions, ultimately achieving safe power extraction. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0030] Reference Figures 1 to 4The illustrated power supply mechanism includes a plug compartment 10, which contains a live wire compartment 11, a neutral wire compartment 12, and a ground wire compartment 13. The live wire compartment 11 is not connected to the neutral wire compartment 12 or the ground wire compartment 13. Both the live wire compartment 11 and the neutral wire compartment 12 have two prongs 14, and the ground wire compartment 13 also has one prong 14. The plug compartment 10 has sockets 15 corresponding to the positions of all the prongs 14. The plug compartment 10 also has sockets connected to the live wire compartment 11, the neutral wire compartment 12, and the ground wire compartment 13. The plug 14 connects to the live wire 16, neutral wire 17, and ground wire 18. It also includes a movable power-gathering component 20. The live wire 16 and neutral wire 17 are normally disconnected, with a first overlap 19 and a second overlap 1a formed at their disconnected ends. Both overlaps are normally open, ensuring the entire plug compartment is de-energized when not in use. Even if an external conductor enters, a short circuit will not occur, improving the safety of the plug-in structure. The movable power-gathering component 20 is movably disposed within the plug compartment 10 and can be reset relative to the plug compartment 10. In use, the movable power-gathering component 20 can slide and push the first overlap 19, electrically connecting the first overlap 19 to the second overlap 1a to form a conductive path. Specifically, the first overlap 19 can directly overlap the second overlap 1a, or it can overlap other structures to achieve an electrical connection with the second overlap 1a. The movable power-gathering component 20 can be driven by other independent structures or in conjunction with an electrical plug. Specifically, when an electrical plug is inserted into the neutral wire compartment 12 and / or the ground wire compartment 13 and engages with the corresponding pin 14, the external electrical plug can push the movable power-gathering component 20 to move within the insertion compartment 10. The outward end of the movable power-gathering component 20 can simultaneously push the first contact portion 19 on the live wire piece 16 and the neutral wire piece 17, so that the first contact portion 19 is electrically connected to the second contact portion 1a to form a conductive path. In some embodiments, the movable power-gathering component 20 moves by sliding, that is, the movable power-gathering component 20 is slidably disposed within the insertion compartment 10, and can slide within the insertion compartment 10 to push the first contact portion 19 or slide back to release the first contact portion 19, so that the first contact portion 19 can be disconnected from the second contact portion 1a.

[0031] In the above embodiments, to improve safety, the live wire compartment 11, neutral wire compartment 12 and ground wire compartment 13 are physically isolated by an insulating partition. It should be noted that each compartment 10 is provided with five sockets 15, and their layout conforms to the new national standard five-socket design (two-pole and three-pole sockets are in the same position). That is, only one of the two-pole sockets and three-pole sockets on each compartment 10 can be used. At the same time, the socket 15 corresponding to the ground wire in the three-pole socket is located between the two sockets 15 of the two-pole sockets, and the three sockets 15 are arranged in a straight line.

[0032] This linkage power extraction mechanism and power output device are designed with a live wire compartment 11, a neutral wire compartment 12, and a ground wire compartment 13 within the insertion compartment 10, ensuring safety within the insertion compartment 10 and preventing short circuits after water ingress. Both the live wire piece 16 and the neutral wire piece 17 include a first overlapping portion 19 and a second overlapping portion 1a, both of which are normally open. This ensures that the entire insertion compartment 10 is de-energized when not in use, preventing short circuits even if an external conductor enters, thus improving the safety of the insertion structure. The designed movable power extraction component 20 can push the first overlapping portion 19 during use, electrically connecting it to the second overlapping portion 1a to form a conductive path. When not in use, the movable power extraction component 20 can retract, disconnecting the first overlapping portion 19 and the second overlapping portion 1a, ultimately achieving safe power extraction and further enhancing the safety of the insertion structure.

[0033] Furthermore, in some embodiments, the linkage power-gathering mechanism further includes a reset member, which is used to retract the movable power-gathering component 20 and / or to disconnect the first contact portion 19 and the second contact portion 1a. That is, the reset member can be used alone to retract the movable power-gathering component 20, while the first contact portion 19 and the second contact portion 1a are disconnected through other structures. Alternatively, the reset member can also be used alone to disconnect the first contact portion 19 and the second contact portion 1a, while the movable power-gathering component 20 is retracted through other structures. In addition, during the process of the reset member driving the movable power-gathering component 20 to retract, the movable power-gathering component 20 can simultaneously drive the first contact portion 19 to retract, or during the process of the reset member driving the first contact portion 19 and the second contact portion 1a to disconnect, the first contact portion 19 can simultaneously push the movable power-gathering component 20 back, so that the movable power-gathering component 20 retracts.

[0034] Furthermore, in some embodiments, a reset element is used solely to retract the movable power-gathering assembly 20. The reset element is a spring 26, with one end connected to the movable power-gathering assembly 20 and the other end connected to the insertion compartment 10 or the external mounting base. When the spring 26 is a tension spring, with one end connected to the movable power-gathering assembly 20 and the other end connected to the insertion compartment 10, the tension spring is stretched when the movable power-gathering assembly 20 pushes against the first overlapping portion 19, and can then be pulled back under the action of elastic tension. When the spring is a compression spring, with one end connected to the movable power-gathering assembly 20 and the other end connected to the external mounting base, the compression spring is compressed when the movable power-gathering assembly 20 pushes against the first overlapping portion 19, and can then be pushed back under the action of elastic thrust.

[0035] The first overlapping portion 19 can disconnect from the second overlapping portion 1a through its own structural characteristics. Furthermore, the first overlapping portion 19 is an elastic structure. When the movable power-taking component 20 pushes the first overlapping portion 19, the first overlapping portion 19 can undergo elastic deformation and abut against the second overlapping portion 1a, thus electrically connecting with the second overlapping portion 1a. After the movable power-taking component 20 moves away from the first overlapping portion 19, the first overlapping portion 19 can disconnect from the second overlapping portion 1a under the action of elastic restoring force.

[0036] Reference Figures 1 to 4 As shown, to facilitate the contact between the first lap joint 19 and the second lap joint 1a, the movable power-collecting assembly 20 includes a sliding seat 21 and a pressing head 22 connected to the sliding seat 21. The sliding seat 21 is slidably installed inside the insertion compartment 10, and the pressing head 22 extends outward from the insertion compartment 10 and has a reset function. A guide slope 23 is provided at the end of the sliding seat 21 away from the pressing head 22. The guide slope 23 forms an angle with the plug insertion direction to convert the axial insertion force of the plug into the lateral sliding displacement of the sliding seat 21. One end with the guide slope 23 is inserted into both the neutral wire compartment 12 and the ground wire compartment 13. When the electrical plug is inserted into the neutral wire compartment 12 and / or the ground wire compartment 13 and mates with the corresponding pin 14, the external electrical plug can abut against the guide slope 23 and push the sliding seat 21 to drive the pressing head 22 to slide in the insertion compartment 10. The outward end of the pressing head 22 can simultaneously push the first overlapping part 19 on the live wire piece 16 and the neutral wire piece 17 to deform and abut against the corresponding second overlapping part 1a on the live wire piece 16 and the neutral wire piece 17 respectively and conduct electricity.

[0037] The insert 10 has a movable hole 1b. A sealing ring (such as a rubber material) is used to dynamically seal the outward end of the pressing head 22 to the movable hole 1b, ensuring the overall sealing and safety of the insert 10. For this purpose, the insert 10 can have an opening, which can be sealed to the pressing head 22 using a sealing ring. Furthermore, a resilient cover 24 is installed inside the movable hole 1b. The pressing head 22 is movably inserted into the resilient cover 24 and extends out of the insert 10, while the sliding seat 21 is completely placed inside the insert 10. The resilient cover 24 seals the movable hole 1b, ensuring the internal sealing of the insert 10. Simultaneously, the sliding seat 21 indirectly pushes the pressing head 22 through the resilient cover 24, achieving both sealing and power drive. Furthermore, to facilitate the installation and fixation of the elastic cover 24, an installation annular groove 1d is provided around the movable hole 1b of the insert 10, and a retaining edge 27 is provided on the outer periphery of the elastic cover 24, which is snapped and fixed in the installation annular groove 1d. The guide seat 1c also seals the elastic cover 24 in the installation annular groove 1d, thus securing the elastic cover 24.

[0038] Furthermore, one end of the pressure head 22 is movably inserted into the elastic cover 24, while the outward end of the pressure head 22 can simultaneously push the first overlapping portion 19 on the live wire piece 16 and the neutral wire piece 17. To facilitate the fixing of the pressure head 22 and ensure its movement, the linkage power extraction mechanism also includes a guide seat 1c. The guide seat 1c is preferably installed on the outside of the insertion compartment 10 and located around the movable hole 1b. The guide seat 1c is provided with a guide structure, and the end of the pressure head 22 located outside the insertion compartment 10 can be slidably mounted on the guide structure. The guide seat 1c is used to restrict the pressure head 22 within the movable hole 1b, and the guide seat 1c is fixed to the outer wall of the insertion compartment 10 by screws. The guide structure is a groove or a slide rail structure, and the pressure head 22 is provided with a structure adapted to the guide structure.

[0039] In some possible implementations, to reset the pressure head 22, a limit post 25 is provided on the pressure head 22, and a return spring 26 is fitted on the limit post 25. The other end of the return spring 26 is connected to the outer wall of the insertion compartment 10 or to an external mounting base. The insertion compartment 10 also needs to be mounted on a housing, and for this purpose, the external mounting base is the housing. In this application, it is preferred that the outward end of the return spring 26 is connected to the external mounting base.

[0040] Reference Figure 5 The power output device shown includes a housing 30, an isolation frame 40, a protective door mechanism 50, and a linkage power extraction mechanism. The plug compartment 10 is installed inside the housing 30. The housing 30 is provided with holes 31 that mate with the plug holes 15. The isolation frame 40 is installed in the area between the plug compartment 10 and the housing 30. The isolation frame 40 and the inner wall of the housing 30 together form a protective chamber 60. The protective door mechanism 50 is installed inside the protective chamber 60. The isolation frame 40 is provided with through holes 41 that mate with all the plug holes 15.

[0041] One end of the return spring 26 abuts against the inner wall of the housing 30, while the periphery of the insertion compartment 10 is fixed to the housing 30 by a mounting ear structure. This structural design can restrict the isolation frame 40 and the protective door mechanism 50 to the housing 30 for fixation. The protective door mechanism 50 can be referred to in patent CN210182651U - Safety door structure and insertion structure for insertion and removal structure or CN112413443A - A specific structure in a waterproof power strip, which will not be described in detail here. In addition, the isolation frame 40 is a plate-shaped structure, which can be installed on the insertion compartment 20 or fixed to the housing 30 by fastening or screw fixing.

[0042] Reference Figure 5As shown, to facilitate protection, the protective door mechanism 50 includes a movable plate 51. The movable plate 51 is provided with a ramp hole 52 adapted to the hole 31 and the insertion hole 15. The movable plate 51 can be reset and installed inside the protective chamber 60. The movable plate 51 is provided with a return spring 53, which is connected to a structure provided on the isolation frame 40 or the housing 30. The spring is used to reset the movable plate 51 to block the insertion hole 15.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
