Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charger. Background Technology

[0002] A charger is a device that connects an electrical appliance to a power source, allowing the appliance to be charged. To charge an appliance using a charger, the charger's prongs must be plugged into the socket of a power outlet to establish an electrical connection.

[0003] However, when the pins are inserted into the socket and the pins are not in complete contact with the metal conductor in the socket, the tiny gap between the pins and the metal conductor will form an "air insulation layer". When the voltage difference between the pins and the metal conductor exceeds the air breakdown threshold, the air molecules will be ionized into plasma, resulting in sparking. The sparks produced by sparking can easily cause discomfort. Utility Model Content

[0004] This application provides a charger that can eliminate the discomfort caused to users by sparks generated by arcing.

[0005] Specifically, a charger includes: Protective case; The electronic control components are installed inside the protective housing; Multiple pins connect to the protective shell; A first conductive wire, the first end of which is electrically connected to the electronic control component, and the second end of which is connected to a first conductive terminal located inside the protective shell; The second conductive wire has a first end electrically connected to the pin and a second end connected to a second conductive terminal located inside the protective shell. A movable component, at least partially located within the protective housing, is movable relative to the first conductive terminal and / or the second conductive terminal under the action of an external force, so as to make the first conductive terminal and the second conductive terminal connected or disconnected.

[0006] The beneficial effects of this application are as follows: When using the charger, before the plug is inserted into the socket, the user can apply external force to the moving part with their hand or other tools, causing the moving part to move under the action of external force, thereby disconnecting the first conductive terminal from the second conductive terminal, and thus disconnecting the plug from the electronic control component. When the plug is inserted into the socket, the plug and the power supply will not form a power circuit, and no voltage exceeding the air breakdown threshold will be generated between the plug and the metal conductor of the power socket, thus preventing arcing during the insertion of the plug into the socket. After the plug is inserted into the socket, the moving part moves under the action of external force, thereby making the first conductive terminal and the second conductive terminal conductive. Since both the first and second conductive terminals are located within the protective shell, even if arcing occurs at the moment of conduction between the first and second conductive terminals, the sparks generated by the arcing are difficult for the user to detect, thus eliminating the discomfort caused by the sparks generated by arcing. In addition, since the first conductive terminal and the second conductive terminal are connected within the protective shell, the protective shell can serve as an insulating shield, preventing sparks generated by arcing from coming into contact with the user and reducing the risk of electric shock.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] This application provides a charger to solve the problem in the related technology that when the plug is inserted into the socket and the plug and the metal conductor in the socket are not in complete contact, the tiny gap between the plug and the metal conductor will form an "air insulation layer". When the voltage difference between the plug and the metal conductor exceeds the air breakdown threshold, the air molecules will be ionized into plasma, resulting in sparking. The sparks produced by sparking are easy to cause discomfort.

[0012] It should be noted that in this application, the charger can be a charging plug, socket, hub, power bank, wireless charger or other device that can connect the electrical device to the power source. The following description uses the charger as an example of a charging plug.

[0013] Specifically, such as Figure 1 As shown, the charger includes a protective shell 10, an electronic control component 20, multiple pins 30, a first conductive wire 40, and a second conductive wire 50.

[0014] The protective shell 10 serves as the outer casing for the charger and can be made of insulating material. An electronic control component 20 is installed within the protective shell 10. The electronic control component 20 may include a circuit board and enables electronic control between the power supply and the device when the device is connected to the power source via the charger. Multiple pins 30 are connected to the protective shell 10. The pins 30 are made of conductive materials such as metal and can be inserted into the socket of a power outlet, allowing power to be drawn from the charger. A first conductive wire 40 has its first end electrically connected to the electronic control component 20, and its second end connected to a first conductive terminal 61 located within the protective shell 10. A second conductive wire 50 has its first end electrically connected to the pins 30, and its second end connected to a second conductive terminal 62 located within the protective shell 10.

[0015] It is understood that the electronic control component 20 and the pin 30 are connected and disconnected through the first conductive line 40 and the second conductive line 50, and the first conductive line 40 and the second conductive line 50 are connected and disconnected through the first conductive terminal 61 and the second conductive terminal 62, thereby enabling the electronic control component 20 and the pin 30 to be connected and disconnected through the first conductive terminal 61 and the second conductive terminal 62.

[0016] When the charger is a wired charger, the charger also includes a power interface 81 of the type such as USB interface, Type-C interface or Lightning interface disposed on the protective case 10. The power control component 20 is electrically connected to the power interface 81. The power interface 81 can be electrically connected to the power device through the charging cable. When the first conductive terminal 61 and the second conductive terminal 62 are connected, the pin 30 is connected to the power interface 81 through the power control component 20, thereby enabling the power device to be connected to the power supply. When the first conductive terminal 61 and the second conductive terminal 62 are disconnected, the pin 30 is disconnected from the power interface 81.

[0017] When the charger is a wireless charger, the charger also includes a charging coil disposed in the protective shell 10. The electronic control component 20 is electrically connected to the charging coil. When the first conductive terminal 61 and the second conductive terminal 62 are connected, the plug 30 is connected to the charging coil through the electronic control component 20. When the charging coil is connected to the power supply, the charging coil can rely on electromagnetic waves to propagate energy. The electromagnetic wave energy transmitted by the charging coil can be converted into electrical energy for the device, thereby providing wireless charging for the device.

[0018] Specifically, the charger also includes a movable member 70, at least a portion of which is located within the protective housing 10. The movable member 70 is movable relative to the first conductive terminal 61 and / or the second conductive terminal 62 under the action of an external force, so as to make the first conductive terminal 61 and the second conductive terminal 62 connected or disconnected.

[0019] Understandably, when using the charger, before the plug 30 is inserted into the socket of the power outlet, the user can use their hand or other tools to apply external force to the movable part 70, causing the movable part 70 to move under the action of external force, thereby disconnecting the first conductive terminal 61 from the second conductive terminal 62, and thus disconnecting the plug 30 from the electronic control component 20. When the plug 30 is inserted into the socket of the power outlet, the plug 30 and the power supply will not form a power circuit, and no voltage of the air breakdown threshold will be generated between the plug 30 and the metal conductor of the power outlet, so that no arcing will occur during the insertion of the plug 30 into the socket.

[0020] When pin 30 is inserted into the socket, the movable part 70 moves under external force, thereby making the first conductive terminal 61 and the second conductive terminal 62 conductive. Since both the first conductive terminal 61 and the second conductive terminal 62 are located inside the protective shell 10, even if arcing occurs at the moment of conduction between the first conductive terminal 61 and the second conductive terminal 62, the sparks generated by the arcing are difficult for the user to detect, thus eliminating the discomfort caused by the sparks. In addition, since the first conductive terminal 61 and the second conductive terminal 62 are conductive inside the protective shell 10, the protective shell 10 can play an insulating role, preventing the sparks generated by arcing from coming into contact with the user and reducing the risk of electric shock.

[0021] See Figures 2 to 4 As shown, in some embodiments of this application, the protective shell 10 includes a first shell 11 and a second shell 12. The electronic control component 20 and the first conductive wire 40 are mounted on the first shell 11. The movable member 70 includes a first mounting portion 71 mounted on the first shell 11, and a first conductive terminal 61 is connected to the first mounting portion 71. The second shell 12 is movably connected to the first shell 11. The movable member 70 also includes a second mounting portion 72 mounted on the second shell 12. The pin 30 and the second conductive wire 50 are mounted on the second shell 12, and the second conductive terminal 62 is connected to the second mounting portion 72.

[0022] The first housing 11 and the second housing 12 are movable relative to each other under the action of external force, so that the first mounting part 71 and the second mounting part 72 are movable relative to each other, thereby making the first conductive terminal 61 and the second conductive terminal 62 movable relative to each other, so that the first conductive terminal 61 and the second conductive terminal 62 are in contact or separated, thereby making the first conductive terminal 61 and the second conductive terminal 62 conduct or disconnect.

[0023] It should be noted that when using the charger, the user can hold the first housing 11 or the second housing 12 and move the first housing 11 or the second housing 12, causing the relative position of the first conductive terminal 61 and the second conductive terminal 62 to change. When the first conductive terminal 61 contacts the second conductive terminal 62 (e.g. Figure 2At this time, the first conductive terminal 61 and the second conductive terminal 62 are connected, thereby making the pin 30 connected to the electronic control component 20; when the first conductive terminal 61 and the second conductive terminal 62 are separated (e.g. Figure 3 and Figure 4 At this time, the first conductive terminal 61 and the second conductive terminal 62 are disconnected, thereby disconnecting the pin 30 from the electronic control component 20.

[0024] It is worth mentioning that the user can drive the first conductive terminal 61 and the second conductive terminal 62 to move relative to each other by operating the first housing 11 and / or the second housing 12 outside the protective case 10, thereby realizing the connection and disconnection of the first conductive terminal 61 and the second conductive terminal 62. This allows the user to maintain good insulation protection with the first conductive terminal 61 and the second conductive terminal 62 during the use of the charger, further improving the safety when using the charger.

[0025] In some embodiments, the first mounting portion 71 may be integrally formed with the first housing 11, or the first mounting portion 71 may be separately formed with the first housing 11 and then spliced ​​by snap-fit, magnetic connection, adhesive, threaded connection or other means. In some embodiments, the first mounting portion 71 may be located on the side of the first housing 11 facing the second housing 12, and the first mounting portion 71 may form a first cavity 13 with the first housing 11. The first mounting portion 71 is provided with a first through hole 711 communicating with the first cavity 13. The electronic control component 20 and the first conductive wire 40 are installed in the first cavity 13, and the first conductive terminal 61 is installed in the first through hole 711 and exposed to the outside of the first housing 11 through the first through hole 711.

[0026] In some embodiments, the second mounting portion 72 may be integrally formed with the second housing 12, or the second mounting portion 72 may be separately formed with the second housing 12 and then spliced ​​by snap-fit, magnetic connection, adhesive, threaded connection or other means. In some embodiments, the second mounting portion 72 may be located on the side of the second housing 12 facing the first housing 11. The second mounting portion 72 and the second housing 12 may surround to form a second cavity 14, and the second mounting portion 72 is provided with a second through hole 721 communicating with the second cavity 14. The first conductive wire 40 is installed in the second cavity 14, and the second conductive terminal 62 is installed in the second through hole 721 and exposed to the outside of the first housing 11 through the second through hole 721. When the first housing 11 and the second housing 12 are rotated relative to each other until the positions of the first through hole 711 and the second through hole 721 are opposite, the first conductive terminal 61 and the second conductive terminal 62 come into contact.

[0027] In some embodiments, the second mounting portion 72 is connected to a pivot 82 (such as...). Figure 6The first housing 11 is rotatably connected to the first mounting part 71, so that the second housing 12 is rotatably connected to the first housing 11. It can be understood that the first housing 11 is rotatably connected to the second housing 12 via the rotating shaft 82, so that the first housing 11 and the second housing 12 can rotate relative to each other around the axis of the rotating shaft 82, thereby allowing the first mounting part 71 and the second mounting part 72 to rotate relative to each other around the axis of the rotating shaft 82, and thus allowing the first conductive terminal 61 and the second conductive terminal 62 to rotate relative to each other around the axis of the rotating shaft 82, thereby realizing the switching of the first conductive terminal 61 and the second conductive terminal 62.

[0028] It should also be noted that in other embodiments, the first housing 11 and the second housing 12 can also be connected in other ways. For example, the first housing 11 can be slidably connected to the second housing 12, and the first housing 11 and the second housing 12 can slide relative to each other along their arrangement direction, so that the first conductive terminal 61 and the second conductive terminal 62 can slide relative to each other, thereby realizing the on / off state of the first conductive terminal 61 and the second conductive terminal 62. In other embodiments, the first housing 11 and the second housing 12 can also be connected in a detachable manner. When the pin 30 is inserted into the socket, the first housing 11 and the second housing 12 are in a separated state, and the first conductive terminal 61 and the second conductive terminal 62 are disconnected. Subsequently, the first housing 11 and the second housing 12 can be connected by snap-fit, magnetic connection, threaded connection or other means.

[0029] like Figures 4 to 6 As shown, in some embodiments, the charger further includes a first limiting member and a second limiting member; the first limiting member is disposed on the first mounting portion 71; and the second limiting member is disposed on the second mounting portion 72.

[0030] Wherein, when the first housing 11 is relative to the second housing 12 about the axis of rotation 82 along the first rotation direction R1 (e.g. Figure 4 When the first conductive terminal 61 contacts the second conductive terminal 62, the second limiting member cooperates with the first limiting member to prevent the first housing 11 from rotating along the first rotation direction R1. It should be noted that the first rotation direction R1 is the extension direction of the axis of rotation 82, and the axial direction of the axis 82 is parallel to the arrangement direction of the first housing 11 and the second housing 12. The first rotation direction R1 can be clockwise or counterclockwise. Through the cooperation of the first and second limiting members, the user is reminded that the first conductive terminal 61 has been rotated to the correct position when it contacts the second conductive terminal 62, thus serving as a positioning reminder. This makes the alignment and contact of the first conductive terminal 61 and the second conductive terminal 62 more accurate and convenient, thereby making the charger more convenient to use.

[0031] In some embodiments, one of the first limiting member and the second limiting member is a limiting groove 83 and the other is a slider 84. The limiting groove 83 extends along the outer periphery of the rotating shaft 82, and the slider 84 is inserted into the limiting groove 83 and can slide along the limiting groove 83.

[0032] When the first housing 11 rotates relative to the second housing 12 along the first rotation direction R1 until the first conductive terminal 61 and the second conductive terminal 62 are in contact, the slider 84 abuts against one end of the limiting groove 83 to prevent the first housing 11 from rotating along the first rotation direction R1. The limiting groove 83 can provide a limit for the slider 84 along the first rotation direction R1. When it is necessary to make the first conductive terminal 61 and the second conductive terminal 62 in contact, it is only necessary to rotate the first housing 11 along the first rotation direction R1 to the limit position (the position when the slider 84 abuts against one end of the limiting groove 83), making the alignment of the first conductive terminal 61 and the second conductive terminal 62 more convenient.

[0033] Furthermore, when the first housing 11 is relative to the second housing 12 along the second rotation direction R2 (e.g.) Figure 4 When the slider 84 is rotated to the point where it contacts the other end of the limiting groove 83, the cooperation between the limiting groove 83 and the slider 84 can also prevent the first housing 11 from continuing to rotate in the second rotation direction R2. The second rotation direction R2 is opposite to the first rotation direction R1. The user can ensure that the first conductive terminal 61 and the second conductive terminal 62 are separated by rotating the first housing 11 to the limit position (the position when the slider 84 contacts the other end of the limiting groove 83) in the second rotation direction R2.

[0034] It should also be noted that in other embodiments, the positioning reminder of the first conductive terminal 61 and the second conductive terminal 62 can also be achieved in other ways. For example, the first limiting member can be a slot, and the second limiting member can be an elastic protrusion. When the first housing 11 moves to the point where the elastic protrusion engages with the slot, the first conductive terminal 61 and the second conductive terminal 62 come into contact. Alternatively, the first limiting member can be a first magnetic member, and the second limiting member can be a second magnetic member. When the first housing 11 moves to the point where the first magnetic member and the second magnetic member are magnetically connected, the first conductive terminal 61 and the second conductive terminal 62 come into contact. Alternatively, the first limiting member can be a first stop, and the second limiting member can be a second stop. The first stop and the second stop are arranged circumferentially along the rotating shaft 82. When the first housing 11 moves to the point where the first stop and the second stop abut against each other, the first conductive terminal 61 and the second conductive terminal 62 come into contact.

[0035] See also Figures 4 to 6As shown, in some embodiments, the rotating shaft 82 can be fixed to the side of the first mounting part 71 facing the second housing 12. The side of the second mounting part 72 facing the first housing 11 can be provided with a bushing 85. The rotating shaft 82 is inserted into the bushing 85. A bearing 86 can be fitted on the rotating shaft 82. The inner ring of the bearing 86 is connected to the outer circumference of the rotating shaft 82, and the outer ring of the bearing 86 is connected to the inner wall of the bushing 85. The rotating shaft 82 is rotatably connected to the bushing 85 through the bearing 86, thereby making the first housing 11 and the second housing 12 rotatably connected. The bearing 86 can reduce the friction when the rotating shaft 82 and the bushing 85 rotate relative to each other, thereby making the rotation faster and smoother. Of course, according to actual needs, the bushing 85 can also be omitted, and the outer circumferential surface of the rotating shaft 82 directly contacts the inner wall of the bushing 85.

[0036] In some embodiments, the charger further includes an annular groove 87 and an annular stop 88. The annular groove 87 is disposed on one of the first mounting portion 71 and the second mounting portion 72. The annular groove 87 extends along the outer periphery of the rotating shaft 82, and the axis of the annular groove 87 coincides with the axis of the rotating shaft 82. The annular stop 88 is disposed on the other of the first mounting portion 71 and the second mounting portion 72. The annular groove 87 extends along the outer periphery of the rotating shaft 82. The annular stop 88 is inserted into the annular groove 87 and can slide along the annular groove 87. The first conductive terminal 61 and the second conductive terminal 62 are both located inside the annular stop 88.

[0037] It is understood that the annular stop 88, the first mounting part 71, and the second mounting part 72 can together enclose a relatively sealed space. The first conductive terminal 61 and the second conductive terminal 62 are both located within this sealed space. The sparks generated when the first conductive terminal 61 and the second conductive terminal 62 come into contact can be isolated by the annular stop 88, preventing the user from sensing the sparks generated when igniting through the gap between the first housing 11 and the second housing 12. In addition, the annular stop 88, the annular groove 87, and the rotating shaft 82 are all coaxially arranged (i.e., their axes coincide), allowing the annular stop 88 to rotate around the same axis as the first housing 11 and the second housing 12, thereby preventing the annular stop 88 from obstructing the relative rotation of the first housing 11 and the second housing 12.

[0038] Specifically, the annular stop 88 can be fixed to the side of the first mounting part 71 facing the second mounting part 72, in which case the annular groove 87 is provided on the side of the second mounting part 72 facing the first mounting part 71; of course, the annular stop 88 can also be fixed to the side of the second mounting part 72 facing the first mounting part 71, in which case the annular groove 87 is provided on the side of the first mounting part 71 facing the second mounting part 72.

[0039] like Figures 7 to 10As shown, in some embodiments of this application, the connection and disconnection between the first conductive terminal 61 and the second conductive terminal 62 can be achieved in other ways. For example, the movable member 70 is movably connected to the protective shell 10. The movable member 70 includes an operating part 73 and a switching part 74 connected to the operating part 73. At least a portion of the operating part 73 is located outside the protective shell 10, and the switching part 74 is located inside the protective shell 10.

[0040] The operating part 73 is movable relative to the protective shell 10 under the action of external force, so that the switching part 74 switches between a first position and a second position, thereby connecting or disconnecting the first conductive terminal 61 and the second conductive terminal 62. It is understood that the user can move the operating part 73 outside the protective shell 10, thereby driving the switching part 74 to move. Through the cooperation of the switching part 74 with the first conductive terminal 61 and the second conductive terminal 62, the connection or disconnection between the first conductive terminal 61 and the second conductive terminal 62 is achieved.

[0041] In some embodiments, the first conductive terminal 61 and the second conductive terminal 62 are provided separately, the switching part 74 is a conductive part, and the operating part 73 is an insulator. The conductive part may be made of conductive metal or other conductive materials, and the operating part 73 may be formed of insulating plastic, insulating rubber or other insulating materials.

[0042] When the on / off section 74 is in the first position (e.g.) Figure 8 The switching part 74 contacts the first conductive terminal 61 and the second conductive terminal 62, so that the first conductive terminal 61 is connected to the second conductive terminal 62 through the switching part 74. When the switching part 74 is in the second position (e.g., Figure 9 When the circuit is open, the switching part 74 separates from the first conductive terminal 61 and the second conductive terminal 62, so that the first conductive terminal 61 and the second conductive terminal 62 are disconnected.

[0043] It is understandable that when the switching part 74 is in the first position, the switching part 74 acts as a "conductive bridge" between the first conductive terminal 61 and the second conductive terminal 62, thereby making the first conductive terminal 61 and the second conductive terminal 62 conductive; when the switching part 74 is in the second position, the switching part 74 is disconnected from the first conductive terminal 61 and the second conductive terminal 62, and since the first conductive terminal 61 and the second conductive terminal 62 are separately provided, the first conductive terminal 61 can be disconnected from the second conductive terminal 62.

[0044] In other embodiments, at least one of the first conductive terminal 61 and the second conductive terminal 62 is an elastic element, the on / off portion 74 is an insulating portion, and the operating portion 73 may also be an insulating portion. The on / off portion 74 and the operating portion 73 may be formed of insulating plastic, insulating rubber or other insulating materials; the elastic element may be a spring, an elastic needle, a spring sheet or other elastic structure.

[0045] When the switching part 74 is in the first position, the switching part 74 is separated from the first conductive terminal 61 and the second conductive terminal 62, and the first conductive terminal 61 is in contact with the second conductive terminal 62, so that the first conductive terminal 61 and the second conductive terminal 62 are connected; when the switching part 74 is in the second position, the switching part 74 is located between the first conductive terminal 61 and the second conductive terminal 62, so that the first conductive terminal 61 and the second conductive terminal 62 are disconnected.

[0046] It is understood that at least one of the first conductive terminal 61 and the second conductive terminal 62 is an elastic element capable of elastic expansion and contraction. When the on / off portion 74 is in the first position, there is no barrier (on / off portion 74) between the first conductive terminal 61 and the second conductive terminal 62, and the first conductive terminal 61 and the second conductive terminal 62 will maintain elastic contact, thereby keeping the first conductive terminal 61 and the second conductive terminal 62 conductive. When the on / off portion 74 is in the second position, the on / off portion 74 can separate the first conductive terminal 61 and the second conductive terminal 62, and the on / off portion 74 plays an insulating barrier role between the first conductive terminal 61 and the second conductive terminal 62, thereby disconnecting the first conductive terminal 61 and the second conductive terminal 62.

[0047] In some embodiments, the first conductive terminal 61 and the second conductive terminal 62 are arranged along a first direction XX, and the movable member 70 is slidably connected to the protective shell 10 along a second direction YY, which is perpendicular to the first direction XX. It is understood that the first direction XX can be any direction. For example, when the protective shell 10 is cylindrical, the first direction XX can be parallel to the axial direction of the protective shell 10, and in this case, the second direction YY can be parallel to any radial direction of the protective shell 10. Alternatively, the first direction XX can also be parallel to the radial direction of the protective shell 10, in which case the second direction YY is parallel to the axial direction of the protective shell 10. For example, when the protective shell 10 is elongated, the first direction XX can also be parallel to the length direction of the protective shell 10. In this case, the second direction YY can be parallel to the width or thickness direction of the protective shell 10. Of course, the first direction XX can also be parallel to the width or thickness direction of the protective shell 10. In this case, the second direction YY can be parallel to the length direction of the protective shell 10. The user can drive the operating part 73 to slide along the second direction YY outside the protective shell 10, so that the on / off part 74 can slide along the second direction YY, thereby allowing the on / off part 74 to switch between the first position and the second position.

[0048] It should also be noted that in other embodiments, the connection and disconnection between the first conductive terminal 61 and the second conductive terminal 62 can also be achieved in other ways. For example, at least one of the first conductive terminal 61 and the second conductive terminal 62 can be slidably connected to the protective shell 10. The first conductive terminal 61 and the second conductive terminal 62 can be driven to slide relative to each other by the on / off part 74, so that the first conductive terminal 61 and the second conductive terminal 62 contact or separate, thereby making the first conductive terminal 61 and the second conductive terminal 62 conduct or disconnect.

[0049] In some embodiments, one of the first conductive terminal 61 and the second conductive terminal 62 may be a conductive pin, and the other of the first conductive terminal 61 and the second conductive terminal 62 may be a conductive spring pin. Of course, in other embodiments, the first conductive terminal 61 and / or the second conductive terminal 62 may be a spring sheet.

[0050] See also Figures 2 to 4 As shown, the plurality of pins 30 include a positive pin 31 and a negative pin 32. The positive pin 31 is used to connect to the positive terminal of the power supply, and the negative pin 32 is used to connect to the negative terminal of the power supply.

[0051] In some embodiments, at least two first conductive lines 40 and two second conductive lines 50 are provided. One first conductive line 40 is a positive conductive line 41, and one first conductive line 40 is a negative conductive line 42. One second conductive line 50 is a positive connecting line 51, and one second conductive line 50 is a negative connecting line 42. The first end of the positive connecting line 51 is electrically connected to the positive pin 31. The positive connecting line 51 is used to electrically connect to the positive conductive line 41 so that the positive pin 31 is electrically connected to the electronic control component 20 through the positive connecting line 51 and the positive conductive line 41. The first end of the negative connecting line 42 is electrically connected to the negative pin 32. The negative connecting line 42 is used to electrically connect to the negative conductive line 42 so that the negative pin 32 is electrically connected to the electronic control component 20 through the negative connecting line 42 and the negative conductive line 42.

[0052] It is understood that in this embodiment, the positive terminal 31 needs to be electrically connected to the electronic control component 20 through the positive connection line 51 and the positive conductive line 41, and the negative terminal 32 needs to be electrically connected to the electronic control component 20 through the negative connection line 42 and the negative conductive line 42. Both the positive conductive line 41 and the negative conductive line 42 are connected to a first conductive terminal 61, and both the positive connection line 51 and the negative connection line 42 are connected to a second conductive terminal 62. When the first conductive terminal 61 of the positive conductive line 41 is connected to the second conductive terminal 62 of the positive connection line 51, and the first conductive terminal 61 of the negative conductive line 42 is connected to the second conductive terminal 62 of the negative connection line 42, the positive terminal... Only when the positive terminal pin 31, the electronic control component 20, and the negative terminal pin 32 form a conductive circuit can arcing occur when the pin 30 is inserted into the socket. When the positive conductive wire 41 is disconnected from the positive connecting wire 51 and / or the negative conductive wire 42 is disconnected from the negative connecting wire 42, the positive terminal pin 31, the electronic control component 20, and the negative terminal pin 32 cannot form a conductive circuit, and arcing will not occur when the pin 30 is inserted into the socket. Therefore, in this embodiment, before the pin 30 is inserted into the socket, the positive conductive wire 41 can be disconnected from the positive connecting wire 51 and / or the negative conductive wire 42 can be disconnected from the negative connecting wire 42 to prevent arcing when the pin 30 is inserted into the socket.

[0053] like Figure 10 As shown, in this embodiment, when the movable part 70 is movably connected to the protective shell 10, the operation part 73 may be provided with two switching parts 74. One switching part 74 controls the switching on and off of the positive conductive line 41 and the positive connecting line 51, and the other switching part 74 controls the switching on and off of the negative conductive line 42 and the negative connecting line 42.

[0054] like Figure 11 As shown, in some other embodiments, the charger may also include a third conductive line 89, the first end of which is electrically connected to the electronic control component 20, the second end of which is electrically connected to one of the positive plug 31 and the negative plug 32, and the first end of the second conductive line 50 is electrically connected to the other of the positive plug 31 and the negative plug 32.

[0055] It is understood that in this embodiment, one of the positive terminal 31 and the negative terminal 32 is directly electrically connected to the electronic control component 20 through the third conductive line 89, and the other of the positive terminal 31 and the negative terminal 32 is electrically connected to the electronic control component 20 through the first conductive line 40 and the second conductive line 50.

[0056] It should also be noted that the multiple pins 30 may also include a neutral pin, which can be directly electrically connected to the electrical control component 20 via a wire.

[0057] It should also be noted that in other embodiments, and in some embodiments of this application, the connection and disconnection between the first conductive terminal 61 and the second conductive terminal 62 can be achieved in other ways. For example, the movable member 70 is movably connected to the protective shell 10, and the movable member 70 is connected to one of the first conductive terminal 61 and the second conductive terminal 62. Taking the connection between the movable member 70 and the first conductive terminal 61 as an example, when the movable member 70 moves relative to the protective shell 10, it drives the first conductive terminal 61 to move, so that the connection and disconnection between the first conductive terminal 61 and the second conductive terminal 62 are achieved; when the movable member 70 is connected to the second conductive terminal 62, when the movable member 70 moves relative to the protective shell 10, it drives the second conductive terminal 62 to move, so that the connection and disconnection between the first conductive terminal 61 and the second conductive terminal 62 are achieved.

[0058] In some embodiments, the protective shell 10 may be provided with a storage groove 15, and the pin 30 may be rotatably connected to the protective shell 10, so that the pin 30 can be in the unfolded position (e.g., Figure 1 ) and storage location (such as Figure 7 Before switching, when the charger is not in use, the plug 30 can be rotated to the storage position. At this time, the plug 30 is located in the storage slot 15, which can reduce the size of the charger and make it more convenient to carry and store the charger.

[0059] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
