Description

Technical Field

[0001] The present application relates to the technical field of power converters, and in particular to a power converter head and a power converter device. Background Art

[0002] Power cords are often equipped with adapter sockets. When the adapter socket on the power cord is disconnected from the plug of an external electronic device, the power cord may still be in contact with the wall plug. At this time, the adapter socket on the power cord is exposed to the outside. Children's fingers or small hardware structures may be inserted into the L / N pole jack on the adapter socket, causing the current to form a loop in the human body, thereby causing the user to be electric shocked. Utility Model Content

[0003] The embodiments of the present application provide a power conversion head and a power conversion device, which can reduce the probability of users getting electric shock due to mis-plugging.

[0004] In a first aspect, an embodiment of the present application provides a power conversion head, including:

[0005] The housing has a receiving cavity and a plug hole connected to the receiving cavity, wherein the plug hole is used for inserting the pins of the plug;

[0006] A conductive component, comprising a first conductive part and a second conductive part, wherein the first conductive part is located in the accommodating cavity, the first conductive part is electrically connected to the second conductive part, the first conductive part is used to contact the pin, and the second conductive part is used to electrically connect to an external power line;

[0007] A protection assembly, comprising an insulating baffle located in the accommodating cavity, wherein the insulating baffle is movably connected to the housing to switch between a protection position and a conduction position, wherein when the insulating baffle is located at the protection position, the insulating baffle is located between the first conductive portion and the plug hole to separate the first conductive portion from the plug hole; when the insulating baffle is located at the conduction position, the first conductive portion is exposed to allow the pin to contact the first conductive portion via the plug hole;

[0008] When the plug pins are inserted into the accommodating cavity through the plug holes at the same time, the plug pins push the insulating baffle to move from the protection position to the conduction position, and the plug pins come into contact with the first conductive portion.

[0009] In a second aspect, the present application further provides a power conversion device, comprising:

[0010] As in any of the above embodiments of the power conversion head, the housing comprises a protrusion, and the jack is provided on the protrusion; and

[0011] A plug, comprising a pin, and the plug has a groove for accommodating the protrusion, and the pin is connected to the bottom wall of the groove;

[0012] When the protrusion is located in the groove, the pin is inserted into the plug hole.

[0013] The beneficial effects of the embodiments of the present application are as follows: an insulating baffle is provided between the first conductive part and the jack, thereby shielding the jack. At this time, when a user inserts a finger into a jack, it will also be blocked by the insulating baffle, so that the finger cannot touch the first conductive part and cause an electric shock due to mis-insertion, thereby reducing the possibility that the user directly contacts the first conductive part through the jack when the plug is not inserted into the jack, thereby reducing the probability of the user being electrocuted by mis-insertion. At the same time, in this embodiment, when the plug is inserted into the jack, multiple pins on the plug will be inserted into the jack at the same time, and multiple pins will contact the insulating baffle, and drive the insulating baffle to move at the same time, at this time, the insulating baffle will move from the protective position to the conductive position, so that the pins can normally contact the first conductive part after the plug is inserted into the jack, thereby preventing the user from being electrocuted by mis-insertion, and allowing the external power supply to be electrically connected to the electronic device through the power conversion head, ensuring that the external power supply can normally power the electronic device.

[0037] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The socket's jack is exposed, and children's fingers or small hardware structures may be inserted into the jack, causing electric shock accidents.

[0039] Regarding the above situation, first of all, please refer to Figure 1-Figure 3 The present application proposes a power conversion head 1, which includes a shell 10, a conductive component 20 and a protective component 30.

[0040] The housing 10 has a receiving cavity (not shown in the figure) and a plug hole 11 connected to the receiving cavity, and the plug hole 11 is used for inserting the pin 41 of the plug 2; Figure 2 As shown, the conductive component 20 includes a first conductive portion 26 and a second conductive portion 27. The first conductive portion 26 is located in the accommodating cavity and is used to contact the pin 41. A portion of the second conductive portion 27 is located in the accommodating cavity and is electrically connected to the first conductive portion 26. Another portion of the second conductive portion 27 can extend out of the accommodating cavity to facilitate electrical connection with the external power line 4 (such as Fig.13 As shown), after the pin 41 of the plug 2 is inserted into the socket 11, the pin 41 can be electrically connected to the first conductive part 26, so that the plug 2 is electrically connected to the external power line 4 through the power conversion head 1, and the normal power supply between the plug 2 and the external power source is realized. Among them, the housing 10 may include an upper cover 14 and a lower cover 15, the upper cover 14 and the lower cover 15 are detachably connected, and the upper cover 14 and the lower cover 15 are surrounded to form a receiving cavity, and the lower cover 15 has an installation cavity, and the first conductive part 26 is fixed in the installation cavity to limit the conductive component 20.

[0041] The protection component 30 includes an insulating baffle 31 located in the accommodating cavity. The insulating baffle 31 is movably connected to the shell 10. The insulating baffle 31 can move relative to the shell 10 to switch between a protection position and a conduction position. When the insulating baffle 31 is in the protection position, the insulating baffle 31 is located between the first conductive portion 26 and the socket 11 to separate the first conductive portion 26 from the socket 11, thereby shielding the socket 11; when the pin 41 is inserted into the accommodating cavity through the socket 11, the pin 41 pushes the insulating baffle 31 to move from the protection position to the conduction position. At this time, the first conductive portion 26 is exposed, and the pin 41 can pass through the socket 11 to contact and conduct the first conductive portion 26.

[0042] Specifically, the insulating baffle 31 is made of an insulating material, is used to isolate the first conductive part 26, and has a high insulating performance. The insulating baffle 31 can directly contact the live part of the first conductive part 26 to play a temporary shielding role. Among them, the insulating baffle 31 can be slidably connected or rotatably connected to the housing 10, and the specific connection and setting method are described in detail below.

[0043] It should be noted that the embodiment of the present application provides an insulating baffle 31 between the first conductive portion 26 and the jack 11, thereby shielding the jack 11. At this time, when a user inserts a finger into a jack 11, it will be blocked by the insulating baffle 31, so that the finger cannot contact the first conductive portion 26 and cause an electric shock due to mis-insertion, thereby reducing the probability of the user being electrocuted by mis-insertion. In this embodiment, when the plug 2 is inserted into the power conversion head 1, the pin 41 on the plug 2 is inserted into the jack 11, and the pin 41 will contact the insulating baffle 31 and drive the insulating baffle 31 to move. At this time, the insulating baffle 31 will move from the protective position to the conductive position, so that the pin 41 can normally contact the first conductive portion 26 after the plug 2 is inserted into the jack 11, thereby preventing the user from being electrocuted by mis-insertion, and ensuring that the plug 2 on the electronic device can be normally connected to the external power cord 4 through the power conversion head 1.

[0044] like Figure 2-Figure 4 As shown, there are multiple sockets 11, and the first conductive portion 26 includes a clamping portion 21 that is arranged one-to-one corresponding to the multiple sockets 11. After the multiple pins 41 are inserted into the sockets 11, each pin 41 is clamped by the clamping portion 21, thereby reducing the shaking of the pins 41 and ensuring that the multiple pins 41 can stably contact and conduct electricity.

[0045] The clamping portion 21 may include a conductive spring sheet. After the plurality of pins 41 are inserted into the socket 11, the pins 41 are inserted into the clamping portion 21. At this time, the pins 41 exert force on the conductive spring sheet, and the conductive spring sheet is deformed, thereby clamping the pins 41, so that the pins 41 are in close contact with the conductive spring sheet, reducing the possibility of the pins 41 being loose, and improving the reliability of the electrical connection between the pins 41 and the first conductive portion 26. Exemplarily, a guiding slope is provided at one end of the clamping portion 21 facing the socket 11. During the process of inserting the pins 41 into the clamping portion 21, the end of the pins 41 first contacts the guiding slope, and then the end of the pins 41 can slide along the guiding slope until entering the clamping portion 21. The guiding slope provides a guiding effect for the pins 41.

[0046] See also Figure 2-Figure 4In some embodiments of the present application, the insulating baffle 31 is slidably connected to the shell 10 along a first direction L1, and the first direction L1 is parallel to the axial direction of the socket 11; the first conductive portion 26 has an accommodation space (not shown in the figure), and the accommodation space is used to accommodate the insulating baffle 31 and the pin 41. The insulating baffle 31 can slide along the first direction L1 in the accommodation space, wherein the accommodation space is extended along the first direction L1 to provide a sliding space for the insulating baffle 31.

[0047] Specifically, the pin 41 is inserted into the jack 11 along the first direction L1, and then the end of the pin 41 contacts the insulating baffle 31, and pushes the insulating baffle 31 to slide along the first direction L1 in the placement space, until the pin 41 enters the placement space and contacts and conducts with the first conductive portion 26. The inner side wall of the first conductive portion 26 encloses and forms a placement space, and the pin 41 contacts the inner side wall of the first conductive portion 26 in the placement space, and the peripheral side of the insulating baffle 31 also contacts the inner side wall of the first conductive portion 26. The placement space provides a sliding space for the insulating baffle 31, and the inner side wall of the first conductive portion 26 provides a limit for the insulating baffle 31 to prevent the insulating baffle 31 from shifting or misaligning during the sliding process.

[0048] It should be noted that when the plug 2 has multiple pins 41, the multiple sockets 11 are evenly spaced. When the plug 2 is inserted into the shell 10, the multiple pins 41 can be inserted into the sockets 11 at the same time, and the multiple pins 41 can contact the insulating baffle 31 at the same time and push the insulating baffle 31 to slide in the installation space along the first direction L1. Taking the example of a plug 2 including two pins 41 and a shell 10 having two sockets 11, the two sockets 11 are arranged in parallel at intervals along the second direction L2, and the second direction L2 is perpendicular to the first direction L1. When a child inserts a finger or a small hardware structure into a single-sided socket 11, a single side of the insulating baffle 31 is subjected to force. At this time, the insulating baffle 31 will tilt due to unbalanced force, so that the sliding direction of the insulating baffle 31 is set at an angle to the extension direction of the guide rail 12, and the peripheral side of the insulating baffle 31 will be squeezed with the inner side wall of the first conductive part 26. The inner side wall of the first conductive part 26 hinders the inclination of the insulating baffle 31, making it difficult for the insulating baffle 31 to slide along the first direction L1 in the installation space, thereby reducing the probability of foreign matter being inserted into the single-sided socket 11 and contacting the first conductive part 26. Taking the example that the plug 2 includes three pins 41 and the shell 10 has three sockets 11, the three sockets 11 are evenly spaced, and the conductive component includes a grounding wire 25 corresponding to the middle socket 11. At this time, even if a foreign object is inserted into the middle socket 11 and pushes the insulating baffle 31 to slide along the first direction, the foreign object contacts the first conductive part 26. However, since the grounding wire 25 is not charged, even if the foreign object contacts the first conductive part 26, no electric shock accident will occur.

[0049] For further information, see Figure 3-Figure 4 In some embodiments of the present application, a guide rail 12 extending along the first direction L1 is provided on the shell 10, and a guide groove 311 is provided on the insulating baffle 31. The insulating baffle 31 is slidably connected to the guide rail 12 through the guide groove 311. The guide rail 12 provides a guiding function for the insulating baffle 31 along the first direction L1 to prevent the insulating baffle 31 from shifting or misaligning during the sliding process.

[0050] It can be understood that, taking the plug 2 including two pins 41 and the shell 10 having two sockets 11 as an example, the two sockets 11 are arranged in parallel at intervals along the second direction L2, and when the insulating baffle 31 is subjected to balanced force, the extension direction of the guide groove 311 is parallel to the first direction L1; when a child inserts a finger or a small hardware structure into a single-sided socket 11, the insulating baffle 31 is subjected to force on one side, and at this time, the insulating baffle 31 will tilt due to unbalanced force, so that the direction of the guide groove 311 on the insulating baffle 31 is also tilted, that is, the extension direction of the guide groove 311 is set at an angle to the extension direction of the guide rail 12, and at this time, the guide groove 311 is difficult to slide relative to the guide rail 12 along the first direction L1, that is, the groove wall of the guide groove 311 will be squeezed between the guide rail 12, thereby preventing the insulating baffle 31 from sliding along the first direction L1 in the installation space, thereby further reducing the probability of foreign matter being inserted from the single-sided socket 11 and contacting the first conductive portion 26.

[0051] For example, Figure 3 As shown, a plurality of guide rails 12 arranged in parallel along the second direction L2 may be provided at the upper cover 14 of the shell 10, and guide grooves 311 corresponding to the plurality of guide rails 12 are provided on the insulating baffle 31, so that when the insulating baffle 31 is tilted, the extension directions of the plurality of guide grooves 311 are all set at an angle with the first direction L1, that is, the extension direction of the guide rail 12 is at an angle with the extension direction of the guide groove 311, so that the insulating baffle 31 is difficult to slide along the extension direction of the guide rail 12, thereby further reducing the probability of foreign matter being inserted through the single-sided jack 11 and contacting the first conductive portion 26.

[0052] For further information, see Figure 2 and Figure 4 In some embodiments of the present application, the protection assembly 30 further includes a first reset member 32, which is connected to the insulating baffle 31 and the housing 10, and is used to reset the insulating baffle 31 to the protection position. The first reset member 32 may be a spring.

[0053] It can be understood that when the pin 41 is just inserted into the socket 11, the pin 41 pushes the insulating baffle 31 to slide from the protection position to the conduction position along the first direction L1, and the first reset member 32 produces elastic deformation. After the pin 41 is fully inserted into the socket 11, the insulating baffle 31 is located in the conduction position under the action of the pin 41; when the pin 41 leaves the socket 11, the insulating baffle 31 loses the external force of the pin 41, and the elastic force of the first reset member 32 pushes the insulating baffle 31 to slide from the conduction position to the protection position.

[0054] See also Figure 5 In some embodiments of the present application, the socket 11 is provided with multiple insulating baffles 31 including a rotating shaft 312, a first blocking portion 313 and two second blocking portions 314. The rotating shaft 312 is rotatably connected to the shell 10 around the axis of the rotating shaft 312. The extension direction of the axis of the rotating shaft 312 is perpendicular to the axial direction of the socket 11. The first blocking portion 313 is located between the two second blocking portions 314. The first blocking portion 313 and the second blocking portion 314 both have a fixed end and a free end that are relatively arranged. The fixed end is connected to the rotating shaft 312, and the free ends of the first blocking portion 313 and the second blocking portion 314 both correspond to one socket 11.

[0055] Specifically, when the plug 2 is not inserted into the socket 11, each blocking portion can block one socket 11. When the plug 2 is inserted into the housing 10, the end of each pin 41 contacts the free end of a blocking portion, and the blocking portion is pushed to rotate around the axis of the rotating shaft 312 to expose the socket 11 and avoid the placement space at the first conductive portion 26, so that the pin 41 can continue to be inserted until the pin 41 is fully inserted into the socket 11 and contacts and conducts electricity with the first conductive portion 26.

[0056] It should be noted that if Figure 6 As shown, there is a snap-in groove between the first blocking portion 313 and the second blocking portion 314, and two snap-in portions are provided at the lower cover 15 of the shell 10. When the insulating baffle 31 is located in the protective position, each snap-in portion cooperates with a snap-in groove, thereby making the setting of the insulating baffle 31 more stable and preventing the first blocking portion 313 or the second blocking portion 314 from tilting when blocking the socket 11.

[0057] The protection assembly 30 further includes a second reset member (not shown in the figure), which is connected to the insulating baffle 31 and the housing 10 and is used to reset the insulating baffle 31 to the protection position, wherein the second reset member may be a torsion spring.

[0058] It can be understood that when the pin 41 is just inserted into the socket 11, the pin 41 pushes the first blocking portion 313 and the second blocking portion 314, and causes the blocking portions to rotate around the axis of the rotating shaft 312, and the second reset member produces elastic deformation. After the pin 41 is fully inserted into the socket 11, the insulating baffle 31 is located in the conduction position under the action of the pin 41; when the pin 41 leaves the socket 11, the first blocking portion 313 and the second blocking portion 314 lose the external force of the pin 41, and the elastic force of the second reset member drives the rotating shaft 312 to rotate, so that the insulating baffle 31 rotates from the conduction position to the protection position.

[0059] See also Figure 6-Figure 7 In some embodiments of the present application, the first conductive portion 26 includes a cantilever 22 disposed toward the rotating shaft 312, and a first limiting groove 315 is provided on a side of the first blocking portion 313 close to the rotating shaft 312. The cantilever 22 is an elastic member, and when the insulating baffle 31 is in the protective position, the cantilever 22 is clamped in the first limiting groove 315, and the first limiting groove 315 can provide a limiting effect for the cantilever 22. At the same time, when the cantilever 22 is clamped in the first limiting groove 315, a force can be provided to the insulating baffle 31 away from the first conductive portion 26 and perpendicular to the hole axis direction of the jack 11, thereby preventing the insulating baffle 31 from shaking at the protective position.

[0060] like Figure 7-Figure 8 As shown, the first blocking portion 313 has a first side surface 3131 disposed toward the plug hole 11, and the second blocking portion 314 has a second side surface 3141 disposed toward the plug hole 11. The fixed side of the first side surface 3131 and the fixed side of the second side surface 3141 are both connected to the rotating shaft 312. The free side of the first side surface 3131 is inclined in a direction away from the plug hole 11, and the free side of the second side surface 3141 is inclined in a direction close to the plug hole 11, that is, the first side surface 3131 and the second side surface 3141 are arranged at an angle. When the insulating baffle 31 is in the protection position, the cantilever 22 is located in the first limiting groove 315, and the first side surface 3131 and the second side surface 3141 block the plug hole 11. When the insulating baffle 31 is rotated to the conducting position, the cantilever 22 leaves the first limiting groove 315, and the first side surface 3131 and the second side surface 3141 are exposed to the plug hole 11, avoiding the placement space at the first conductive portion 26 to facilitate the insertion of the pin 41.

[0061] Specifically, the cantilever 22 is located in the first limiting groove 315, and the end of the cantilever 22 contacts the side wall of the first limiting groove 315. Fig. 9As shown in (a), when the pin 41 pushes the first blocking portion 313, the end of the pin 41 applies a force F to the first side surface 3131, and the first side surface 3131 is inclined in a direction away from the socket 11. Therefore, the force F applied by the pin 41 to the first side surface 3131 has a first component force F1 away from the rotating shaft 312. The first component force F1 facilitates pushing the first blocking portion 313 to rotate in a direction close to the first conductive portion 26, thereby allowing the cantilever 22 to leave the first limiting groove 315 and the insulating baffle 31 to rotate to the conduction position.

[0062] like Fig. 9 As shown in (b), when a foreign object (such as a child's finger or a small hardware structure) is inserted into one or both of the sockets 11 corresponding to the second blocking portion 314, the end of the foreign object applies a force F to the second side surface 3141, and the second side surface 3141 is inclined toward the direction close to the socket 11. Therefore, the force F exerted by the foreign object on the second side surface 3141 has a second component force F2 toward the direction of the rotation axis 312. The action of the second component force F2 will cause interference between the side wall of the first limiting groove 315 and the cantilever 22, thereby hindering the rotation of the insulating baffle 31, and the insulating baffle 31 is difficult to rotate around the axis of the rotation axis 312, thereby reducing the probability of foreign objects being inserted from the socket 11 corresponding to the second blocking portion 314 and contacting the first conductive portion 26.

[0063] It is easy to understand that the length of the middle pin 41 on the plug 2 is longer than the length of the pins 41 on both sides, so that when the plug 2 is inserted into the shell 10, the middle pin 41 can first push the insulating baffle 31 to rotate, exposing the placement space at the first conductive part 26, so that the pins 41 on both sides can be smoothly inserted into the jack 11 and contact with the first conductive part 26.

[0064] For further information, see Fig.10 In some embodiments of the present application, the first conductive part 26 includes a live wire 23, a neutral wire 24 and a ground wire 25, the ground wire 25 is located between the live wire 23 and the neutral wire 24, and the ground wire 25 is arranged corresponding to the first blocking part 313, the live wire 23 and the neutral wire 24 are arranged corresponding to the second blocking part 314, and the live wire 23, the neutral wire 24 and the ground wire 25 are used to contact the pin 41. It is easy to understand that a foreign object can be inserted into the jack 11 corresponding to the first blocking part 313, that is, the foreign object is inserted into the jack 11 located in the middle, and the foreign object pushes the insulating baffle 31 to rotate so that the foreign object contacts the first conductive part 26, but since the ground wire 25 is not charged, even if the foreign object contacts the first conductive part 26, no electric shock accident will occur.

[0065] Specifically, the live wire 23, the neutral wire 24 and the ground wire 25 are all electrically connected to the clamping part 21. The live wire 23 and the clamping part 21 together form the L pole of the power conversion head 1, the neutral wire 24 and the clamping part 21 together form the N pole of the power conversion head 1, and the ground wire 25 and the clamping part 21 together form the E pole of the power conversion head 1.

[0066] For further information, see Fig.11 In some embodiments of the present application, a second limiting groove 316 is provided on the side of the first blocking portion 313 away from the first side surface 3131. When the insulating baffle 31 rotates from the protection position to the conduction position, the cantilever 22 leaves the first limiting groove 315 and enters the second limiting groove 316, wherein the width of the first limiting groove 316 along the axial direction of the rotating shaft 312 is greater than the width of the cantilever 22 along the axial direction of the rotating shaft 312, and when the cantilever 22 is located in the second limiting groove 316, the side wall of the cantilever 22 contacts the side wall of the second limiting groove 316, so that the second limiting groove 316 provides a limiting effect for the cantilever 22 to prevent the cantilever 22 from shifting or misaligning during the rotation of the insulating baffle 31, and the second limiting groove 316 can also reduce the shaking of the cantilever 22.
