[0025] 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.

[0026] The utility model embodiment provides a charger, such as Figures 1 to 4As shown, the charger includes a rotating pin 10, a conductive member 20 and a circuit board 30. The rotating pin 10 is electrically connected to the circuit board 30 through the conductive member 20, wherein the conductive member 20 is provided with a clamping and limiting structure 21, an abutting structure 22 and a positioning structure 23. The clamping and limiting structure 21 and the positioning structure 23 are located on both sides of the abutting structure 22 and are both electrically connected to the abutting structure 22. The circuit board 30 is inserted into the clamping and limiting structure 21 and is electrically connected to the clamping and limiting structure 21. The rotating pin 10 is electrically connected to the abutting structure 22. The positioning structure 23 is used to position the conductive member 20.

[0027] The present application provides a clamping and limiting structure 21, an abutting structure 22 and a positioning structure 23 on the conductive part 20 of the charger; the abutting structure 22 is electrically connected to the rotating pin 10; the positioning structure 23 is used to position the conductive part 20; the circuit board 30 is plugged into the clamping and limiting structure 21, and has a certain limiting effect on the conductive part 20; by separating the positioning structure 23 and the clamping and limiting structure 21 on both sides of the abutting structure 22, two-point positioning is achieved, the risk of displacement of the conductive part 20 is reduced, the abutting structure 22 remains electrically connected to the rotating pin 10, and the stability of the electrical connection between the conductive part 20 and the rotating pin 10 is improved.

[0028] The rotating pin 10 can be connected to the mains to obtain electrical energy, and transmit the electrical energy to the circuit board 30 through the conductive member 20. The circuit board 30 can convert the mains and output a lower voltage to charge the electronic equipment.

[0029] The conductive member 20 may be in the shape of a sheet, a strip, etc. In this embodiment, the conductive member 20 is preferably in the shape of a sheet. The sheet-shaped conductive member 20 has a certain elasticity, and can provide a certain pressure and resistance during the connection with the rotating pin 10. The elastic contact can ensure a stable electrical connection and reduce poor contact caused by vibration, shock or temperature change.

[0030] refer to Figure 4 In this embodiment, the clamping and limiting structure 21, the abutting structure 22 and the positioning structure 23 are integrally formed, and the positioning structure 23 includes a first positioning section 231 and a second positioning section 232. The first positioning section 231 is electrically connected to the clamping and limiting structure 21 through the second positioning section 232, and the second positioning section 232 extends outward to form an abutting structure 22 that is electrically connected to the rotating pin 10.

[0031] The clamping and limiting structure 21, the abutting structure 22 and the positioning structure 23 are integrally formed, and the abutting structure 22 is formed by extending outwardly from the second positioning section 232 of the positioning structure 23. The conductive part 20 as a whole has the advantages of good conductive performance, structural stability, small size, light weight and high production efficiency. Specifically, the clamping and limiting structure 21, the abutting structure 22 and the positioning structure 23 are integrally formed, and can usually be made of highly conductive materials, such as copper, aluminum, etc. These materials have good conductive properties and can effectively conduct current, reduce resistance, and reduce energy loss; they are manufactured using a one-time molding process, without welding joints or connectors, and therefore have high structural stability, they are not easy to loosen, fall off or have poor contact, and can provide reliable electrical connections; the one-piece molding can be mass-produced through efficient production processes such as injection molding and die casting, and has higher production efficiency than manual production or welding connection methods, which can reduce manufacturing costs and improve production efficiency.

[0032] Furthermore, the abutment structure 22 includes an abutment block 221 and an elastic transition section 222 . The abutment block 221 is electrically connected to the rotating pin 10 . The elastic transition section 222 is arranged at an obtuse angle to the abutment end surface of the abutment block 221 and is electrically connected to the second positioning section 232 .

[0033] By providing the elastic transition section 222, and the elastic transition section 222 and the abutting end surface of the abutting block 221 are arranged at an obtuse angle, the abutting block 221 has a certain elastic abutting activity space, and elastically abuts against the rotating pin 10, effectively reducing the contact resistance and the possibility of poor contact, which is conducive to the stable transmission of current, reducing energy loss and voltage reduction, and further ensuring the stability and reliability of the electrical connection between the abutting block 221 and the rotating pin 10.

[0034] refer to Figures 2 to 4 In this embodiment, the charger also includes a shell 40, and the clamping and limiting structure 21 includes a first clamping portion 211, a supporting portion 212, and a second clamping portion 213 that are electrically connected in sequence. The circuit board 30 is inserted and clamped between the first clamping portion 211 and the second clamping portion 213, and abuts against the supporting portion 212, so that the supporting portion 212 is pressed and positioned on the shell 40.

[0035] By providing the first clamping portion 211, the abutting portion 212 and the second clamping portion 213, a clamping force is provided between the first clamping portion 211 and the second clamping portion 213 to clamp and position the circuit board 30, thereby achieving a stable electrical connection between the circuit board 30 and the conductive member 20. At the same time, the circuit board 30 has a certain limiting effect on the conductive member 20 in the reverse direction, thereby reducing the risk of displacement of the conductive member 20.

[0036] During the specific assembly process, the operator inserts and clamps the circuit board 30 between the first clamping part 211 and the second clamping part 213, so that the electrode end on the circuit board 30 abuts against the first clamping part 211 and / or the second clamping part 213 for electrical connection, and the circuit board 30 abuts against the abutting part 212, and the conductive member 20 is pressed and positioned on the housing 40, which has a certain limiting effect on the conductive member 20. Compared with the method of directly welding the circuit board 30 to the conductive member 20, the electrical connection method of the circuit board 30 and the conductive member 20 of the present application is more flexible in assembly and convenient for maintenance.

[0037] refer to Figures 2 to 4 The first clamping portion 211 includes a first connecting section 2111 and a first bending section 2112, and the first bending section 2112 is electrically connected to the abutting portion 212 through the first connecting section 2111. The second clamping portion 213 includes a second connecting section 2131 and a second bending section 2132, and the second bending section 2132 is electrically connected to the abutting portion 212 through the two connecting sections. The second bending section 2132 is bent toward the first bending section 2112, and the circuit board 30 is clamped between the first bending section 2112 and the second bending section 2132.

[0038] The first bending section 2112 and the second bending section 2132 are bent toward each other, forming a clamping force therebetween, thereby increasing the mechanical stability between the circuit board 30 and the conductive member 20, preventing relative movement or loosening therebetween, and ensuring good contact therebetween, which helps to ensure the stability of the electrical connection and reduce contact resistance and the possibility of poor contact.

[0039] In this embodiment, the positioning structure 23 also includes at least one first positioning hole 233, and the housing 40 is provided with a first positioning column 41 that cooperates with the first positioning hole 233. The conductive member 20 can be positioned on the housing 40 through the cooperation between the first positioning hole 233 and the first positioning column 41 on the housing 40. The number of the first positioning holes 233 can be one, two, or more than two, and the designer can set them according to actual needs. In this embodiment, it is preferred to set two first positioning holes 233, and two corresponding first positioning columns 41 are provided on the housing 40. The first positioning column 41 passes through the first positioning hole 233 to position the conductive member 20 on the housing 40.

[0040] The first positioning hole 233 may be specifically provided on the first positioning section 231 of the positioning structure 23 .

[0041] In other embodiments, the first positioning hole 233 may be provided on the housing 40 , and the first positioning column 41 may be provided on the conductive member 20 , so as to realize the positioning of the conductive member 20 .

[0042] refer to Figures 2 to 4In this embodiment, a receiving groove seat 42 is recessed inwardly on the outer circumference of the shell 40, and the rotating pin 10 can be rotatably accommodated in the receiving groove seat 42. The charger also includes a limiting member 50 for limiting the rotating pin 10. The limiting member 50 is fixed in the shell 40 and presses the positioning structure 23 of the conductive member 20 to be positioned on the receiving groove seat 42.

[0043] The rotating pin 10 can be rotated between the charging position and the storage position. When the charger is needed, the rotating pin 10 is rotated to the charging position and can be inserted into the corresponding power supply device to obtain electrical energy; when the charger is not needed, the rotating pin 10 is rotated to the storage position, and the rotating pin 10 is accommodated in the storage slot 42, which is convenient for storing and carrying the charger.

[0044] By setting the limiting member 50, the rotating pin 10 can be limited to prevent the rotating pin 10 from shifting. At the same time, the limiting member 50 can also position the positioning structure 23 of the conductive member 20 on the receiving slot 42, further positioning the conductive member 20 on the receiving slot 42, and further reducing the risk of displacement of the conductive member 20.

[0045] In specific configuration, the limiting member 50 includes a limiting body 51 and an elastic limiting portion 52. The limiting body 51 is provided with an opening 53, and the elastic limiting portion 52 is provided at the opening 53. The limiting body 51 positions the positioning structure 23 of the conductive member 20 on the receiving slot 42, and the elastic limiting portion 52 elastically abuts against the rotating pin 10 to limit the rotating pin 10.

[0046] In this embodiment, there are two conductive members 20, and the rotating pin 10 includes two pins 11 and a rotating shaft 12. The two pins 11 are respectively disposed at both ends of the rotating shaft 12 and are respectively abutted and electrically connected to a contact structure 22 of a conductive member 20. The charger can be connected to two electrodes of an external power supply device through the two pins 11 to obtain electrical energy, and the two conductive members 20 can transmit the electrical energy obtained by the two pins 11 to the circuit board 30.

[0047] Further, refer to Figure 2 , Figure 3 and Figure 5 A second positioning hole (not shown) is provided on the rotating shaft 12, and the pin 11 includes a pin body 111 and a second positioning column 112 that cooperates with the second positioning hole. The second positioning column 112 is perpendicular to the pin body 111 and penetrates the second positioning hole to position the pin 11 on the rotating shaft 12, and the second positioning column 112 is electrically connected to the abutment structure 22.

[0048] The pin 11 is assembled with the shaft 12 by passing the second positioning post 112 of the pin 11 through the second positioning hole on the shaft 12, and the pin 11 can be electrically connected to the abutment structure 22 of the conductive member 20 through its second positioning post 112, which is easy to assemble and has an ingenious structure.

[0049] In this embodiment, reference Figure 2 and Figure 3 A first limit block 43 and a second limit block 44 are provided on the shell 40, and the first limit block 43 and the second limit block 44 are spaced apart along the axial direction of the rotating shaft 12. A positioning block 121 is provided on the rotating shaft 12, and the positioning block 121 is clamped between the first limit block 43 and the second limit block 44.

[0050] By arranging the first limit block 43 and the second limit block 44 on the housing 40, the rotating shaft 12 is limited in the axial direction of the rotating shaft 12, and then the rotating pin 10 is limited in the axial direction of the rotating shaft 12, so as to prevent the rotating pin 10 from accidentally detaching from the conductive member 20 during use, ensure the stable contact between the rotating pin 10 and the abutment structure 22, help reduce the contact resistance and the possibility of poor contact, and improve the stability of the electrical connection.
