[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0034] The utility model embodiment provides a plug device, such as Figures 1 to 5 As shown, the plug device includes a housing 1, a circuit board 2, a rotating pin 3, a rotating limiter 4, a first conductive member 5 and a second conductive member 6.

[0035] The circuit board 2 is disposed on the housing 1 .

[0036] The rotating pin 3 is rotatably arranged on the housing 1. When in use, the rotating pin 3 can be rotated to the charging position and the storage position. When the plug device needs to be used, the rotating pin 3 can be rotated to the charging position by an external force, inserted into the corresponding power supply device, and conduct the electric energy to the plug device. When the plug device is not needed, the rotating pin 3 can be rotated to the storage position by an external force, thereby reducing the space occupied by the entire plug device and facilitating storage and carrying.

[0037] The rotation limiter 4 is used to limit the rotation pin 3 on the housing 1. The rotation limiter 4 can limit the rotation pin 3 to prevent the rotation pin 3 from shifting on the housing 1. The rotation limiter 4 is provided with a first avoidance space 4a and a second avoidance space 4b, and the two conductive ends of the rotation pin 3 are exposed in the first avoidance space 4a and the second avoidance space 4b respectively.

[0038] The first conductive member 5 and the second conductive member 6 are both fixedly electrically connected to the circuit board 2. Specifically, the first conductive member 5 and the second conductive member 6 can be fixedly welded to the circuit board 2 by welding, and the first conductive member 5 and the second conductive member 6 are electrically connected to the electrodes on the circuit board 2 through solder to conduct electrical energy.

[0039] When the circuit board 2 is assembled in the housing 1, the first conductive member 5 and the second conductive member 6 pass through the first avoidance space 4a and the second avoidance space 4b respectively, and are respectively in electrical contact with the two conductive ends of the rotating pin 3. The first avoidance space 4a and the second avoidance space 4b provide guide sockets for the first conductive member 5 and the second conductive member 6 to be connected with the two conductive ends of the rotating pin 3.

[0040] The present application achieves a fixed electrical connection between the first conductive member 5 and the second conductive member 6 and the circuit board 2, and sets a first avoidance space 4a and a second avoidance space 4b on the rotation limit member 4 that limits the rotating pin 3 to the shell 1. The first avoidance space 4a and the second avoidance space 4b provide docking guide sockets that allow the first conductive member 5 and the second conductive member 6 to correspond to the two conductive ends of the rotating pin 3. When the circuit board 2 is assembled to the shell 1, the assembler does not need to constantly observe and adjust the position of the circuit board 2. The first conductive member 5 and the second conductive member 6 directly pass through the corresponding first avoidance space 4a and the second avoidance space 4b, and respectively correspond to the two conductive ends of the rotating pin 3 for electrical connection, thereby achieving alignment and stable electrical connection assembly between the conductive member on the circuit board 2 and the two conductive ends of the rotating pin 3, and the operation is convenient.

[0041] In this embodiment, reference Figures 2 to 5 The housing 1 is provided with a first limiting groove 11 corresponding to the position of one conductive end of the rotating pin 3 and a second limiting groove 12 corresponding to the position of the other conductive end of the rotating pin 3. The first limiting groove 11 cooperates with the first conductive member 5 to accommodate the first conductive member 5.

[0042] The second limiting groove 12 cooperates with the second conductive member 6 to accommodate the second conductive member 6 .

[0043] When the first conductive member 5 passes through the first avoidance space 4 a and is electrically connected to a conductive end of the rotating pin 3 , it can be correspondingly inserted into the first limiting groove 11 on the accommodating shell 1 , thereby further limiting the first conductive member 5 on the shell 1 .

[0044] Similarly, when the second conductive member 6 passes through the second avoidance space 4b and is electrically connected to the other conductive end of the rotating pin 3, it can be correspondingly inserted into the second limiting groove 12 on the shell 1, thereby further limiting the second conductive member 6 on the shell 1 and further improving the stability of the electrical connection between the two conductive members and the two conductive ends of the rotating pin 3.

[0045] In this embodiment, reference Figures 2 to 5 At least one support bone is provided on the bottom wall of the first limiting groove 11 and / or the second limiting groove 12 , and the support bone abuts against the first conductive member 5 and / or the second conductive member 6 when the circuit board 2 is assembled in the housing 1 .

[0046] Since the first conductive member 5 and the second conductive member 6 are electrically connected to the two conductive ends of the rotating pin 3, a large amount of heat will be generated during the transmission of electrical energy. By providing a support frame, the first conductive member 5 and the second conductive member 6 can be lifted up, and while providing support for the first conductive member 5 and the second conductive member 6, the contact area between the first conductive member 5 and the second conductive member 6 and the housing 1 is reduced, and the contact area between the first conductive member 5 and the second conductive member 6 and the air is increased, which has a certain heat dissipation effect.

[0047] Specifically, at least one support bone can be provided on the bottom wall of the first limiting groove 11 or the second limiting groove 12, or at least one support bone can be provided on the bottom wall of the first limiting groove 11 and the second limiting groove 12. The support bone lifts up the first conductive member 5 or the second conductive member 6 so that it does not abut against the bottom wall of the corresponding limiting groove, providing a certain heat dissipation space, thereby improving the heat dissipation effect to a certain extent.

[0048] The number of support bones can be one, two or more, and the user can set it according to actual needs. Preferably, in this embodiment, the first support bone 13 and the second support bone 14 are both provided on the bottom wall of the first limiting groove 11 and the second limiting groove 12, and the first support bone 13 and the second support bone 14 are arranged at intervals on the bottom wall of the first limiting groove 11 and / or the second limiting groove 12. The first support bone 13 and the second support bone 14 abut against the first conductive member 5 and / or the second conductive member 6 after the circuit board 2 is assembled to the housing 1.

[0049] The gap between the first support bone 13 and the second support bone 14 provided at intervals provides a space for heat dissipation for the first conductive member 5 and / or the second conductive member 6, while stably supporting the first conductive member 5 and / or the second conductive member 6.

[0050] In this embodiment, reference Figures 4 to 6 The rotation limiter 4 includes a main body 41, a first extension body 42, and a second extension body 43. The main body 41 extends outward to opposite sides to form the first extension body 42 and the second extension body 43. A first avoidance space 4a is formed between the first extension body 42 and the main body 41, and a second avoidance space 4b is formed between the second extension body 43 and the main body 41. The first avoidance space 4a and the second avoidance space 4b are as shown in FIG. Figure 2 and Figure 3 as shown in .

[0051] In this embodiment, the first avoidance space 4a is formed by the gap between the first extension body 42 and the main body 41, and the second avoidance space 4b is formed by the gap between the second extension body 43 and the main body 41, and the processing is relatively simple.

[0052] In other embodiments, two openings may be opened on the main body 41 of the rotation limiter 4 as the first avoidance space 4a and the second avoidance space 4b, exposing the two conductive ends of the rotating pin 3 for the first conductive member 5 and the second conductive member 6 to pass through, thereby realizing electrical connection between the two conductive members on the circuit board 2 and the rotating pin 3.

[0053] refer to Figure 6 The rotation limit member 4 is provided with a first positioning portion 44, a second positioning portion 45 and a third positioning portion 46, which are arranged in a triangle. The first positioning portion 44 is arranged on the first extension body 42, the second positioning portion 45 is arranged on the second extension body 43, and the third positioning portion 46 is arranged on the main body 41. The rotation limit member 4 is positioned on the shell 1 by the first positioning portion 44, the second positioning portion 45 and the third positioning portion 46.

[0054] The first positioning portion 44 , the second positioning portion 45 and the third positioning portion 46 on the rotation limiting member 4 form a triangular stable structure, so that the rotation limiting member 4 can be stably positioned on the housing 1 , and further stably limit the rotation pin 3 on the housing 1 .

[0055] Specifically, the first positioning portion 44 and the second positioning portion 45 can be positioning holes, and a positioning column matched with the positioning holes is provided on the housing 1. The third positioning portion 46 can be a locking hole, and a locking hole is also provided on the housing 1. By passing the locking member through the two locking holes, the rotation limit member 4 can be locked and positioned on the housing 1.

[0056] refer to Figure 3 and Figure 7 In this embodiment, the rotating pin 3 includes a rotating shaft 31 and two pins 32 connected to the rotating shaft 31. The main body 41 is also provided with an opening and an elastic limiting portion 47 disposed at the opening. The elastic limiting portion 47 elastically abuts against the rotating shaft 31.

[0057] The two pins 32 serve as two conductive ends, and are electrically connected to two conductive parts on the circuit board 2 internally, respectively, to conduct electric energy to the circuit board 2. Externally, the two pins 32 can be plugged into an external power supply device to obtain electric energy, and conduct the electric energy to the circuit board 2 through the two conductive parts. The material of the two pins 32 can be copper, copper alloy, gold-plated material, stainless steel and other conductive materials.

[0058] When the rotating pin 3 rotates from the charging position to the storage position, or from the storage position to the charging position, the elastic limiting portion 47 on the rotation limiting member 4 elastically abuts against the rotating pin 3 to limit the rotating pin 3 on the housing 1.

[0059] refer to Figure 2 , Figure 5 and Figure 7In this embodiment, the first conductive member 5 and / or the second conductive member 6 includes an electrical connection section 51, a positioning section 52 and an elastic abutting section 53 which are connected in sequence. The electrical connection section 51 is fixedly electrically connected to the circuit board 2, the positioning section 52 abuts against the housing 1 when the circuit board 2 is assembled in the housing 1, and the elastic abutting section 53 abuts against and electrically connects with a conductive end of the rotating pin 3 when the circuit board 2 is assembled in the housing 1.

[0060] The elastic abutment section 53 can elastically abut against one conductive end of the rotating pin 3, providing a certain elasticity between the conductive member and the conductive end of the rotating pin 3, so that it can absorb impact and vibration; relieve stress concentration, and reduce the degree of stress concentration when the conductive member abuts against the conductive end of the rotating pin 3; the elastic abutment can tolerate a certain deviation or deformation, making it easier to align and install during assembly. In short, the elastic abutment can provide better impact absorption, stress dispersion, and convenience of assembly and maintenance, and further improve the reliability and stability of the electrical connection between the conductive member and the conductive end of the rotating pin 3.

[0061] In a specific configuration, the elastic abutment section 53 may be disposed obliquely upward relative to the positioning section 52 .

[0062] Furthermore, the electrical connection section 51 is provided with three connection terminals, and three connection holes corresponding to the connection terminals are provided on the circuit board 2. The conductive member passes through the connection holes on the circuit board 2 through the three connection terminals, is fixedly connected to the circuit board 2 by welding, and is electrically connected to the electrodes on the circuit board 2. The connection between the conductive member and the circuit board 2 is stable.

[0063] The three connection terminals may be arranged in an enclosed manner or arranged in a row.

[0064] In specific applications, the first conductive member 5 and the second conductive member 6 can be in the shape of a sheet or a strip. In this embodiment, the first conductive member 5 and the second conductive member 6 are preferably in the shape of a sheet. Compared with a strip, a sheet-shaped conductive member has a larger surface area, that is, a larger contact area with the air, and has a better heat dissipation effect.

[0065] In this embodiment, reference Figure 7 The circuit board 2 is provided with an avoidance area 2a for avoiding the rotating pin 3 and the rotating stopper 4. When the circuit board 2 is assembled in the housing 1, the rotating pin 3 and the rotating stopper 4 are just accommodated in the avoidance area 2a on the circuit board 2, making the structure between the circuit board 2 and the housing 1 more compact, which is conducive to the miniaturization of the overall structure of the plug device.

[0066] Furthermore, a third avoidance space may be provided on the housing 1 for avoiding components of the circuit board 2, so that after the circuit board 2 is assembled in the housing 1, the overall structure is more compact, which is conducive to the miniaturization of the overall structure of the plug device.

[0067] The plug device of the present application can be applied to a charger or a mobile power supply. The corresponding charger or mobile power supply can obtain electrical energy by plugging into a power supply device through the plug device.

[0068] The present application also provides a preferred embodiment of a charger.

[0069] The charger of the present application includes a data cable and a plug device as described above. The data cable is electrically connected to the circuit board 2 of the plug device to obtain electrical energy. The data cable can be connected to an electronic device to transmit electrical energy to the electronic device to charge the electronic device.

[0070] In the charger of the present application, the plug device is configured to electrically connect the first conductive member 5 and the second conductive member 6 to the circuit board 2 in a fixed manner, and to provide a first avoidance space 4a and a second avoidance space 4b on the rotation limit member 4 that limits the rotating pin 3 to the shell 1. The first avoidance space 4a and the second avoidance space 4b provide docking guide sockets that allow the first conductive member 5 and the second conductive member 6 to correspond to the two conductive ends of the rotating pin 3. When the circuit board 2 is assembled to the shell 1, the assembler does not need to constantly observe and adjust the position of the circuit board 2. The first conductive member 5 and the second conductive member 6 directly pass through the corresponding first avoidance space 4a and the second avoidance space 4b, and are respectively electrically connected to the two conductive ends of the rotating pin 3, thereby achieving alignment and stable electrical connection assembly between the conductive member on the circuit board 2 and the two conductive ends of the rotating pin 3, which is convenient to operate.
