Description

[Technical Field]

[0001] The present application relates to the technical field of power converters, and more particularly to power conversion adapters and power conversion devices. [Background technology]

[0002] A power cord is usually equipped with a converter plug adapter, and when the converter plug adapter body on the power cord is separated from the plug of the external electronic device, the power cord still comes into contact with the wall outlet. In this case, the converter plug adapter body on the power cord is exposed to the outside, and if a child's finger or small metal part is inserted into the L / N pole socket on the converter plug adapter body, the current may form a circuit in the human body, causing the user to receive an electric shock. Summary of the Invention

[0003] The embodiments of the present application provide a power conversion adapter and a power conversion device that can reduce the probability of electric shock due to incorrect insertion by a user.

[0004] In a first aspect, a power conversion adapter according to an embodiment of the present application includes: a housing having a receiving cavity and a receptacle communicating with the receiving cavity, the receptacle being adapted for receiving a plug blade; a conductive assembly including a first conductive part and a second conductive part, the first conductive part being located within the receiving cavity and electrically connected to the second conductive part for contacting the blade, the second conductive part being electrically connected to an external power line; a protection assembly including an insulating barrier located within the accommodating cavity, the insulating barrier being movably connected to the housing and switchable between a protection position and a conducting position, the insulating barrier being located between the first conductive portion and the receptacle and separating the first conductive portion from the receptacle when the insulating barrier is in the protection position, and the first conductive portion being exposed when the insulating barrier is in the conducting position, and the blades being in contact with the first conductive portion through the receptacle; When the blades are simultaneously inserted into the receiving cavity through the receptacle, they push the insulating barrier to move from the protective position to the conducting position and contact the first conductive portion.

[0005] In a second aspect, a power conversion device according to the present application includes: The power conversion adapter according to any one of the above embodiments, wherein the housing includes a protrusion, and the outlet is formed on the protrusion; a plug including a blade and having a recessed groove for accommodating the protrusion, the blade being connected to a bottom wall of the recessed groove; When the protrusion is positioned within the groove, the blade is inserted into the socket.

[0006] The beneficial effects of the present embodiment are as follows: By providing an insulating barrier between the first conductive part and the receptacle, the receptacle is shielded. In this case, even if a user inserts a finger into one of the receptacles, the insulating barrier will block the finger and prevent the finger from coming into contact with the first conductive part and receiving electric shock due to incorrect insertion. This reduces the possibility of the user directly contacting the first conductive part through the receptacle when inserting the plug into the receptacle, thereby reducing the probability of electric shock due to incorrect insertion. Furthermore, when the plug of this embodiment is inserted into the receptacle, multiple blades on the plug are simultaneously inserted into the receptacle and contact the insulating barrier, causing the insulating barrier to move. In this case, the insulating barrier moves from the protective position to the conductive position, allowing the blades to normally contact the first conductive part after the plug is inserted into the receptacle. This prevents electric shock due to incorrect insertion and ensures that the external power source is electrically connected to the electronic device via the power adapter and properly supplies power to the electronic device.

[0009] In order to more clearly explain the technical means in the embodiments of the present application or related art, the following description will be made clearly and completely with reference to the drawings in the embodiments of the present application, but it should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative work are all within the scope of protection of the present application.

[0010] If the socket of the power outlet is exposed to the outside, a small child's finger or a small metal part may be inserted into the socket, resulting in an electric shock accident.

[0011] In response to the above situation, in a first aspect, the present application provides a power conversion adaptor 1 including a housing 10, a conductive assembly 20, and a protective assembly 30, as shown in FIGS.

[0012] The housing 10 has a receiving cavity (not shown) and a receptacle 11 communicating with the receiving cavity, into which the blades 41 of the plug 2 are inserted. As shown in FIG. 2 , the conductive assembly 20 includes a first conductive portion 26 and a second conductive portion 27. The first conductive portion 26 is located within the receiving cavity and is adapted to contact the blades 41. A portion of the second conductive portion 27 is located within the receiving cavity and is electrically connected to the first conductive portion 26. Another portion of the second conductive portion 27 extends from the receiving cavity and is electrically connected to the external power line 4 (as shown in FIG. 13 ). Thus, when the blades 41 of the plug 2 are inserted into the receptacle 11, the blades 41 may be electrically connected to the first conductive portion 26. Thus, the plug 2 is electrically connected to the external power line 4 by the power conversion adapter 1, thereby realizing normal power supply between the plug 2 and the external power source. The housing 10 may include an upper cover 14 and a lower cover 15, the upper cover 14 being removably connected to the lower cover 15, the upper cover 14 and the lower cover 15 enclosing an accommodating cavity, the lower cover 15 having a mounting cavity, and the first conductive portion 26 being fixed within the mounting cavity to positionally restrict the conductive assembly 20.

[0013] The protection assembly 30 includes an insulating barrier 31 located within the accommodating cavity, which is movably connected to the housing 10 and is movable relative to the housing 10 so as to be switched between a protecting position and a conducting position, and when the insulating barrier 31 is in the protecting position, it is located between the first conductive portion 26 and the receptacle 11 and separates the first conductive portion 26 from the receptacle 11, thereby shielding the receptacle 11, and when the blade 41 is inserted into the accommodating cavity through the receptacle 11, it pushes the insulating barrier 31 to move it from the protecting position to the conducting position, in which case the first conductive portion 26 is exposed and the blade 41 can pass through the receptacle 11 and contact the first conductive portion 26 to conduct electricity.

[0014] Specifically, the insulating barrier 31 is made of an insulating material, isolates the first conductive part 26, and has high insulating properties. The insulating barrier 31 can directly contact the live part on the first conductive part 26 and perform a temporary shielding function. The insulating barrier 31 may be slidably or rotatably connected to the housing 10, and specific connection and installation methods will be described in detail below.

[0015] In the embodiment of the present application, an insulating barrier 31 is provided between the first conductive part 26 and the receptacle 11 to shield the receptacle 11. In this case, even if a user inserts a finger into one of the receptacles 11, the insulating barrier 31 blocks the insertion of the finger, preventing the finger from coming into contact with the first conductive part 26 and receiving an electric shock due to incorrect insertion. This reduces the probability of electric shock due to incorrect insertion. In this embodiment, when the plug 2 is inserted into the power conversion adapter 1, the blades 41 on the plug 2 are inserted into the receptacle 11 and contact the insulating barrier 31, thereby moving the insulating barrier 31. In this case, the insulating barrier 31 moves from the protective position to the conductive position, allowing the blades 41 to normally contact the first conductive part 26 after the plug 2 is inserted into the receptacle 11. This prevents electric shock due to incorrect insertion and ensures that the plug 2 of the electronic device is normally connected to the external power line 4 by the power conversion adapter 1.

[0016] As shown in Figures 2 to 4, a plurality of sockets 11 are provided, and the first conductive part 26 includes clamping parts 21 provided in one-to-one correspondence with the plurality of sockets 11, and after the plurality of blades 41 are inserted into the sockets 11, each blade 41 is properly clamped by the clamping parts 21, reducing the vibration of the blades 41 and ensuring stable contact and conductivity among the plurality of blades 41.

[0017] The clamping part 21 may include a conductive spring, and after a plurality of blades 41 pass through the socket 11, the blades 41 are inserted into the clamping part 21. In this case, the blades 41 apply a force to the conductive spring, which deforms and tightly holds the blades 41, thereby bringing the blades 41 and the conductive spring into close contact, reducing the possibility of the blades 41 shaking and improving the reliability of the electrical connection between the blades 41 and the first conductive part 26. For example, a guide slope is provided at the end of the clamping part 21 facing the socket 11, and when the blades 41 are inserted into the clamping part 21, the end of the blade 41 first comes into contact with the guide slope and then slides along the guide slope until it enters the clamping part 21, and the guide slope acts to guide the blades 41.

[0018] As shown in Figures 2 to 4, in some embodiments of the present application, the insulating barrier 31 and the housing 10 are connected to be slidable along a first direction L1, which is parallel to the axial direction of the socket 11, the first conductive part 26 has an accommodating space (not shown) that accommodates the insulating barrier 31 and the blade 41, the insulating barrier 31 can slide along the first direction L1 within the accommodating space, and the accommodating space extends along the first direction L1 to provide a sliding space for the insulating barrier 31.

[0019] Specifically, the blade 41 is inserted into the socket 11 in the first direction L1, and then the end of the blade 41 contacts the insulating barrier 31, pushing the insulating barrier 31 and sliding it into the receiving space in the first direction L1 until the blade 41 enters the receiving space and contacts the first conductive part 26, thereby establishing electrical conductivity. The receiving space is surrounded by the inner wall of the first conductive part 26, and the blade 41 contacts the inner wall of the first conductive part 26 within the receiving space, and the periphery of the insulating barrier 31 also contacts the inner wall of the first conductive part 26. The receiving space provides a sliding space for the insulating barrier 31, and the inner wall of the first conductive part 26 restricts the position of the insulating barrier 31, preventing it from being displaced or shifted during sliding.

[0020] Furthermore, when the plug 2 has multiple blades 41, the multiple sockets 11 are uniformly spaced apart, and when the plug 2 is inserted into the housing 10, the multiple blades 41 are inserted into the sockets 11 at the same time, come into contact with the insulating barrier 31 at the same time, and push the insulating barrier 31 to slide into the accommodating space along the first direction L1. For example, if the plug 2 includes two blades 41 and the housing 10 has two sockets 11, the two sockets 11 are arranged in parallel and spaced apart along the second direction L2, which is perpendicular to the first direction L1. When a child's finger or a small metal part is inserted into one of the sockets 11 on one side, one side of the insulating barrier 31 will receive the force. In this case, the insulating barrier 31 will be tilted due to the uneven force received, and the sliding direction of the insulating barrier 31 will form an angle with the extension direction of the guide rail 12. This will press the circumferential side of the insulating barrier 31 against the inner wall of the first conductive part 26, which will prevent the insulating barrier 31 from tilting, making it difficult for the insulating barrier 31 to slide along the first direction L1 within the accommodating space. This will reduce the probability of a foreign object being inserted into one of the sockets 11 and coming into contact with the first conductive part 26. For example, if the plug 2 includes three blades 41 and the housing 10 has three sockets 11, the three sockets 11 are uniformly spaced apart, and the conductive assembly includes a ground wire 25 corresponding to the middle socket 11. In this case, even if a foreign object is inserted into the middle socket 11 and pushes the insulating barrier 31 to slide along the first direction and come into contact with the first conductive part 26, the ground wire 25 will not be charged, and therefore no electric shock accident will occur even if the foreign object comes into contact with the first conductive part 26.

[0021] Furthermore, as shown in Figures 3 and 4, in some embodiments of the present application, the housing 10 is provided with a guide rail 12 extending along the first direction L1, and the insulating barrier 31 is provided with a guide groove 311, and the insulating barrier 31 is slidably connected to the guide rail 12 by the guide groove 311, and the guide rail 12 acts to guide the insulating barrier 31 along the first direction L1, preventing the insulating barrier 31 from being displaced or shifted during sliding.

[0022] As can be understood, for example, if the plug 2 includes two blades 41 and the housing 10 has two sockets 11, the two sockets 11 are arranged in parallel at an interval along the second direction L2, and when the force received by the insulating barrier 31 is uniform, the extension direction of the guide groove 311 is parallel to the first direction L1. When a child's finger or a small metal member is inserted into one of the sockets 11 on one side, the force is received by one side of the insulating barrier 31. In this case, the insulating barrier 31 will be tilted due to the unevenness of the force received, and The direction of the guide groove 311 on the insulating barrier 31 is also inclined, that is, the extension direction of the guide groove 311 and the extension direction of the guide rail 12 form an angle. In this case, the guide groove 311 is less likely to slide in the first direction L1 relative to the guide rail 12. In other words, the groove wall of the guide groove 311 and the guide rail 12 are pressed against each other, preventing the insulating barrier 31 from sliding in the first direction L1 within the accommodating space. This reduces the probability of a foreign object being inserted through one of the sockets 11 and coming into contact with the first conductive part 26.

[0023] For example, as shown in FIG. 3, the upper cover 14 of the housing 10 may be provided with a plurality of guide rails 12 arranged in parallel along the second direction L2, and the insulating barrier 31 may be provided with guide grooves 311 corresponding to the plurality of guide rails 12. When the insulating barrier 31 is inclined, the extension directions of the plurality of guide grooves 311 all form an angle with the first direction L1. In other words, the extension directions of the guide rails 12 and the guide grooves 311 form an angle, making it difficult for the insulating barrier 31 to slide along the extension direction of the guide rails 12, thereby reducing the probability of a foreign object being inserted through one of the sockets 11 and coming into contact with the first conductive part 26.

[0024] 2 and 4, in some embodiments of the present application, the protection assembly 30 further includes a first return member 32, which is connected to the insulating barrier 31 and the housing 10 and returns the insulating barrier 31 to the protective position. The first return member 32 may be a spring.

[0025] As can be seen, when the blade 41 is inserted into the socket 11, the blade 41 pushes the insulating barrier 31 along the first direction L1, causing it to slide from the protection position to the conductive position, and elastically deforms the first reset member 32; after the blade 41 is fully inserted into the socket 11, the insulating barrier 31 is in the conductive position due to the action of the blade 41; when the blade 41 is removed from the socket 11, the insulating barrier 31 is not subjected to external force from the blade 41, and the elastic force of the first reset member 32 pushes the insulating barrier 31, causing it to slide from the conductive position to the protection position.

[0026] As shown in FIG. 5 , in some embodiments of the present application, there are multiple sockets 11, and the insulating barrier 31 includes a rotating shaft 312, a first interrupting portion 313, and two second interrupting portions 314, the rotating shaft 312 and the housing 10 are rotatably connected around the axis of the rotating shaft 312, the axis of the rotating shaft 312 extends perpendicular to the axial direction of the socket 11, the first interrupting portion 313 is located between the two second interrupting portions 314, and the first interrupting portion 313 and the second interrupting portion 314 each have a fixed end and a free end opposite to each other, the fixed end is connected to the rotating shaft 312, and the free ends of the first interrupting portion 313 and the second interrupting portion 314 each correspond to one socket 11.

[0027] Specifically, when the plug 2 is not inserted into the socket 11, each interrupting part shields one socket 11, and when the plug 2 is inserted into the housing 10, the end of each blade 41 contacts the free end of one of the interrupting parts and presses the free end of the interrupting part to rotate the interrupting part around the axis of the rotating shaft 312, exposing the socket 11 and avoiding the storage space of the first conductive part 26, so that the blade 41 can be easily and continuously inserted until it is completely inserted into the socket 11 and comes into contact with the first conductive part 26 to establish conductivity.

[0028] As shown in Figure 6, there is an engagement groove between the first blocking part 313 and the second blocking part 314, and two engagement parts are provided on the lower cover 15 of the housing 10. When the insulating barrier 31 is in the protective position, each engagement part fits into one engagement groove, making the installation of the insulating barrier 31 more stable and preventing the first blocking part 313 or the second blocking part 314 from tilting when shielding the socket 11.

[0029] The protective assembly 30 further includes a second return member (not shown), which is connected to the insulating barrier 31 and the housing 10 and returns the insulating barrier 31 to the protective position, and the second return member may be a torsion spring.

[0030] As can be seen, when the blade 41 is inserted into the socket 11, the blade 41 presses the first and second interrupting portions 313, 314, causing the interrupting portions to rotate around the axis of the rotating shaft 312 and elastically deforming the second return member; after the blade 41 is fully inserted into the socket 11, the insulating barrier 31 is in the conductive position due to the action of the blade 41; when the blade 41 is removed from the socket 11, the first and second interrupting portions 313, 314 are not subjected to external force from the blade 41, but instead drive the rotating shaft 312 to rotate due to the elastic force of the second return member, thereby rotating the insulating barrier 31 from the conductive position to the protective position.

[0031] 6 and 7 , in some embodiments of the present application, the first conductive portion 26 includes a cantilever 22 provided toward the rotation axis 312, and a first position limiting groove 315 is formed on the side of the first blocking portion 313 that is closer to the rotation axis 312. The cantilever 22 is an elastic member, and when the insulating barrier 31 is in the protective position, the cantilever 22 is engaged in the first position limiting groove 315, which can limit the position of the cantilever 22. Furthermore, when the cantilever 22 is engaged in the first position limiting groove 315, it applies an acting force to the insulating barrier 31 in a direction away from the first conductive portion 26 and in an axial direction perpendicular to the socket 11, preventing the insulating barrier 31 from shaking in the protective position.

[0032] As shown in Figures 7 and 8, the first blocking section 313 has a first side surface 3131 facing toward the socket 11, and the second blocking section 314 has a second side surface 3141 facing toward the socket 11, and both the fixed side of the first side surface 3131 and the fixed side of the second side surface 3141 are connected to the rotating shaft 312, and the free side of the first side surface 3131 is inclined toward a direction away from the socket 11, and the free side of the second side surface 3141 is inclined toward a direction closer to the socket 11, that is, the inclination direction of the first side surface 3131 and the inclination direction of the second side surface 3141 form an angle. When the insulating barrier 31 is in the protective position, the cantilever 22 is located within the first position limiting groove 315, and in this case, the first side surface 3131 and the second side surface 3141 shield the socket 11. When the insulating barrier 31 rotates to the conductive position, the cantilever 22 moves away from the first position limiting groove 315, and the first side surface 3131 and the second side surface 3141 move to expose the socket 11, avoiding the storage space for the first conductive part 26, allowing the plug blade 41 to be easily inserted.

[0033] Specifically, when the cantilever 22 is positioned within the first position limiting groove 315 and the end of the cantilever 22 contacts the side wall of the first position limiting groove 315 and the blade 41 presses the first blocking portion 313 as shown in Figure 9(a), the end of the blade 41 applies an acting force F to the first side surface 3131, tilting the first side surface 3131 in a direction away from the socket 11. As a result, the acting force F of the blade 41 on the first side surface 3131 has a first component force F1 away from the rotation axis 312, and this first component force F1 easily rotates the first blocking portion 313 in a direction approaching the first conductive portion 26, so that the cantilever 22 moves away from the first position limiting groove 315 and the insulating barrier 31 rotates to the conductive position.

[0034] As shown in Figure 9(b), when a foreign object (e.g., a child's finger or a small metal part) is inserted through one or two sockets 11 corresponding to the second blocking part 314, the end of the foreign object applies an acting force F to the second side surface 3141, tilting the second side surface 3141 in a direction approaching the socket 11. As a result, the acting force F of the foreign object on the second side surface 3141 has a second component force F2 toward the rotation axis 312. Due to the action of this second component force F2, the side wall of the first position limiting groove 315 interferes with the cantilever 22, preventing the rotation of the insulating barrier 31 and making it difficult for the insulating barrier 31 to rotate around the axial line of the rotation axis 312. This reduces the probability that the foreign object will be inserted through the socket 11 corresponding to the second blocking part 314 and come into contact with the first conductive part 26.

[0035] As can be easily understood, the length of the middle blade 41 on the plug 2 is longer than the length of the blades 41 on both sides. Therefore, when the plug 2 is inserted into the housing 10, the middle blade 41 takes the initiative to push the insulating barrier 31 to rotate, exposing the accommodating space for the first conductive part 26, so that the blades 41 on both sides can be smoothly inserted into the socket 11 and easily come into contact with the first conductive part 26.

[0036] 10 , in some embodiments of the present application, the first conductive portion 26 includes a phase wire 23, a neutral wire 24, and a ground wire 25, the ground wire 25 is located between the phase wire 23 and the neutral wire 24 and is provided corresponding to the first interrupting portion 313, the phase wire 23 and the neutral wire 24 are provided corresponding to the second interrupting portion 314, and the phase wire 23, the neutral wire 24, and the ground wire 25 are for contacting the blade 41. As can be easily understood, a foreign object may be inserted into the outlet 11 corresponding to the first interrupting portion 313. That is, the foreign object is inserted into the intermediate outlet 11 and rotates the insulating barrier 31, thereby contacting the first conductive portion 26. Since the ground wire 25 is not charged, no electric shock hazard will occur even if the foreign object comes into contact with the first conductive portion 26.

[0037] Specifically, the phase wire 23, the neutral wire 24 and the ground wire 25 are all electrically connected to the clamping portion 21, and the phase wire 23 and the clamping portion 21 together form the L pole of the power conversion adapter 1, the neutral wire 24 and the clamping portion 21 together form the N pole of the power conversion adapter 1, and the ground wire 25 and the clamping portion 21 together form the E pole of the power conversion adapter 1.

[0038] Furthermore, as shown in FIG. 11 , in some embodiments of the present application, a second position limiting groove 316 is formed on the side of the first blocking portion 313 away from the first side surface 3131. When the insulating barrier 31 rotates from the protection position to the conduction position, the cantilever 22 leaves the first position limiting groove 315 and enters the second position limiting groove 316. The width of the second position limiting groove 316 along the axial direction of the rotation axis 312 is greater than the width of the cantilever 22 along the axial direction of the rotation axis 312. When the cantilever 22 is located within the second position limiting groove 316, the side wall of the cantilever 22 comes into contact with the side wall of the second position limiting groove 316, so that the second position limiting groove 316 acts to limit the position of the cantilever 22, preventing the cantilever 22 from being displaced or shifted during the rotation of the insulating barrier 31. The second position limiting groove 316 can also reduce the swinging of the cantilever 22. Furthermore, when the cantilever 22 is engaged in the second position limiting groove 316, the free end of the first blocking portion 313 is sandwiched between the cantilever 22 and the blade 41, thereby preventing the insulating barrier 31 from shaking in the conductive position.

[0039] In a second aspect, as shown in Figures 12 and 13, a power conversion device 3 according to an embodiment of the present application includes a plug 2 and the power conversion adapter 1 according to any one of the above embodiments, and the plug 2 includes a plug blade 41 that can be inserted into the socket 11.

[0040] The power conversion device 3 in this embodiment may include an adapter plug and a conversion adapter body, where the adapter plug is a conversion plug 2 and the conversion adapter body is a conversion power conversion adapter 1, and the adapter plug can be electrically connected to an electronic device, and the conversion adapter body can be electrically connected to a power line 4, so that the electronic device can be electrically connected to different power sources through the conversion adapter body.

[0041] As shown in Figures 12 and 13, the housing 10 includes a protrusion 13, the socket 11 is formed with the protrusion 13, the plug 2 has a groove 42 that accommodates the protrusion 13, the blades 41 are connected to the bottom wall of the groove 42, and when the protrusion 13 is positioned within the groove 42, the blades 41 are inserted into the socket 11.

[0042] Specifically, the housing 10 may further include a case 16 (as shown in FIG. 2 ), which covers the outside of the upper cover 14 and the lower cover 15 and provides protection and cushioning for components such as the first conductive part 26 within the receiving cavity. A portion of the case 16 forms the protrusion 13, and the first conductive part 26 and the protective assembly 30 are located inside the protrusion 13. The groove 42 provides a mounting space for the protrusion 13, and its inner wall contacts and supports the protrusion 13, reducing vibration when the plug 2 and the power conversion adapter 1 are connected, thereby improving the stability of the electrical connection between the plug 2 and the power conversion adapter 1.
