[0039] For details, please refer to Figures 1 to 11 The embodiment of the present application provides an electrical connection structure. The electrical connection structure includes a pin 30 and a spring 40. The spring 40 is connected with at least two abutting portions. The at least two abutting portions abut against different areas of the pin 30 respectively and are electrically connected.

[0040] In the embodiment of the present application, at least two abutting portions are connected to the spring sheet 40, so that the at least two abutting portions are electrically connected to different regions of the pin 30. Thus, at least two contact points can be provided between the pin 30 and the spring sheet 40, thereby increasing the contact area, reducing the contact impedance, and improving the output power. At the same time, based on the redundant setting of the contact points, when the electrical connection at one of the contact points is disconnected, the remaining contact points can ensure a reliable electrical connection between the pin 30 and the spring sheet 40, which can improve the fault tolerance of the electrical connection between the pin 30 and the spring sheet 40.

[0041] The pin 30, as a component of the socket of the socket, can be made of metal material. For example, the pin 30 is made of copper. The spring 40, as a conductive elastic component connecting the pin 30 and the circuit board, can also be made of metal material. For example, the spring 40 is made of copper.

[0042] At least two abutting portions can be integrally formed on the spring sheet 40. For example, two abutting portions are provided. The two abutting portions are integrally formed on one end of the spring sheet 40, and the two abutting portions are spaced apart. Thus, the two abutting portions are respectively abutted against two regions of the pin 30 and electrically connected.

[0043] At least two abutting portions may also be welded to the spring sheet 40. For example, three abutting portions are provided. The three abutting portions are welded to one end of the spring sheet 40, and the three abutting portions are spaced apart. Thus, the three abutting portions are respectively abutted against the three regions of the pin 30 and electrically connected.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the electrical connection structure further includes a base 10 and a rotating member 20. The rotating member 20 is rotatably mounted on the base 10. The spring 40 is fixed to the base 10. The pin 30 is connected to the rotating member 20 and rotates with the rotating member 20.

[0045] By fixing the spring sheet 40 to the base 10 and connecting the pin 30 to the rotating member 20, the pin 30 can be driven to rotate by the rotation of the rotating member 20 on the base 10, thereby forming a rotatable and foldable pin 30 structure. When applied to a power adapter, a foldable power adapter can be formed, which is convenient for carrying the power adapter and protecting the pin 30.

[0046] The base 10 is made of insulating material. For example, the base 10 is made of plastic, polymer resin and other materials. The rotating member 20 is also made of insulating material. For example, the rotating member 20 is made of plastic, polymer resin and other materials.

[0047] The electrical connection structure in the embodiments of the present application is applicable to plugs, power adapters, etc. In some embodiments, when the plug and the power adapter are used to electrically connect a two-hole socket, two spring clips 40 may be fixed on the base 10, and each spring clip 40 is respectively provided with at least two abutment portions. Two pins 30 are connected to the rotating member 20. One pin 30 is electrically connected to one spring clip 40 to serve as a neutral wire and a live wire, respectively. In some embodiments, when the plug and the power adapter are used to electrically connect a three-hole socket, three spring clips 40 may be fixed on the base 10, and each spring clip 40 is respectively provided with at least two abutment portions. Three pins 30 are connected to the rotating member 20. One pin 30 is electrically connected to one spring clip 40 to serve as a neutral wire, a live wire, and a ground wire, respectively.

[0048] like Figure 3 and Figure 5As shown, the electrical connection structure in the embodiment of the present application is particularly suitable for electrically connecting a two-hole socket. At this time, two pins 30 are installed on the rotating member 20 so that the two pins 30 rotate synchronously. Since the rotating member 20 is made of insulating material, a short circuit between the two pins 30 can be prevented. Two springs 40 can be arranged on the base 10 at intervals, and the springs 40 correspond to the pins 30 one by one. Among them, the shapes of the two springs 40 can be the same or different. Or, as Figure 7 and Figure 8 As shown, the two spring sheets 40 have different shapes, but the shapes of at least two abutting portions connected to the two spring sheets 40 are the same.

[0049] like Fig. 9 and Fig.11 As shown, the rotating member 20 may include a rotating shaft and connectors at both ends of the rotating shaft. A mounting portion is provided on the base 10. The rotating shaft is rotatably arranged on the mounting portion. The two connectors are respectively located on opposite sides of the mounting portion to prevent the mounting portion from interfering with the rotation of the connectors.

[0050] In some embodiments, the rotating member 20 may be an injection molded member. For example, the rotating member 20 is connected to the base 10 and the pin 30 by injection molding.

[0051] like Figure 3 and Figure 5 As shown, in some embodiments, two abutting portions are provided, namely, a first abutting portion 410 and a second abutting portion 420 which are spaced apart. The pin 30 is fixed to the rotating member 20 through the conductive member 50. The pin 30 abuts against and is electrically connected to the conductive member 50. The first abutting portion 410 abuts against and is electrically connected to the pin 30. The second abutting portion 420 abuts against and is electrically connected to the conductive member 50.

[0052] It is understandable that the first abutting portion 410 abuts against the plug pin 30, and the second abutting portion 420 abuts against the conductive member 50. Since the conductive member 50 is electrically connected to the plug pin 30, the spring 40 can form a plurality of contact points electrically connected to the plug pin 30. For example, the first abutting portion 410 and the plug pin 30 can form one contact point, and the second abutting portion 420 and the conductive member 50 can form two contact points.

[0053] The conductive member 50 may be made of metal material. For example, the conductive member 50 may be made of copper. In some embodiments, the conductive member 50 may be configured as a metal rivet, a metal screw, or the like.

[0054] Connecting holes may be provided at opposite ends of the rotating member 20 , the conductive member 50 is disposed in the connecting holes, and the pin 30 is fixed to the rotating member 20 .

[0055] like Fig. 9 and Fig.10As shown, in some embodiments, the pin 30 includes a first connection portion 310. The rotating member 20 is formed with a mounting hole 210. The first connection portion 310 is disposed in the mounting hole 210. The first connection portion 310 has an outlet end 320 passing through the mounting hole 210. The outlet end 320 abuts against the first abutting portion 410 and is electrically connected.

[0056] It can be understood that the first connection portion 310 of the pin 30 extends toward the direction of the rotating member 20 and is inserted into the mounting hole 210 of the rotating member 20. The end of the first connection portion 310 away from the pin 30 passes through the mounting hole 210 and forms a protruding end 320. The protruding end 320 is abutted against the first abutting portion 410 and electrically connected to achieve electrical connection between the pin 30 and the spring 40. The protruding end 320 and the pin 30 are respectively located on both sides of the mounting hole 210. That is, the pin 30 and the protruding end 320 are respectively located on both sides of the rotating shaft. When the pin 30 rotates, the protruding end 320 can be pressed against the first abutting portion 410, thereby ensuring that the protruding end 320 and the first abutting portion 410 are tightly fitted.

[0057] In some embodiments, the first connection portion 310 is integrally formed with the pin 30. For example, the first connection portion 310 and the pin 30 are integrally stamped or cast. The protruding end 320 is a portion of the first connection portion 310. This portion fits with the first abutting portion 410 to achieve electrical connection between the pin 30 and the spring 40.

[0058] The passing end 320 may be configured as an arc-shaped surface to reduce the friction between the passing end 320 and the first abutting portion 410 and prevent the passing end 320 from scratching the first abutting portion 410 .

[0059] In some embodiments, the first abutting portion 410 includes a first arc segment 4110, a first oblique segment 4120, and a second arc segment 4130 connected in sequence. The plug pin 30 has a first state and a second state. In the first state, the first arc segment 4110 abuts against the outlet end 320 and is electrically connected. In the second state, the second arc segment 4130 abuts against the outlet end 320 and is electrically connected. The plug pin 30 rotates with the rotating member 20 to switch between the first state and the second state.

[0060] It is understandable that the pin 30 can rotate with the rotating member 20 so that the pin 30 has a first state and a second state. Figure 1 As shown, the first state is a state perpendicular to the base 10. Figure 2 As shown, the second state is the state where the pin 30 is retracted into the base 10. Thus, the pin 30 can be used to plug the power adapter into the socket when in the first state, and the pin 30 can be used to store the power adapter when in the second state.

[0061] like Figure 3 and Figure 4 As shown, when the plug pin 30 is in the first state, the outlet end 320 abuts against the first arc segment 4110. At this time, the electrical transmission path is: spring sheet 40-first arc segment 4110-outlet end 320-first connecting portion 310-plug pin 30. Thus, the spring sheet 40 and the plug pin 30 are electrically connected. Figure 5 and Figure 6 As shown, when the plug pin 30 is in the second state, the outlet end 320 abuts against the second arc segment 4130. At this time, the electrical transmission path is: spring piece 40-first arc segment 4110-first oblique segment 4120-second arc segment 4130-outlet end 320-first connecting portion 310-plug pin 30. Thus, the electrical connection between the spring piece 40 and the plug pin 30 is achieved.

[0062] The first arc segment 4110 and the second arc segment 4130 of the first abutting portion 410 are adapted to the first state and the second state of the plug pin 30 respectively, so as to ensure that the plug pin 30 can form an electrical connection with the spring sheet 40 in both the first state and the second state.

[0063] The first oblique section 4120 serves as a transition section between the first arc section 4110 and the second arc section 4130, and is used to space the first arc section 4110 and the second arc section 4130 to accommodate the position of the corresponding outlet end 320 of the pin 30 in the first state and the position of the corresponding outlet end 320 in the second state.

[0064] In some embodiments, the first arc segment 4110 and the second arc segment 4130 themselves have a certain elasticity, so that they can be elastically deformed to a certain extent when they are in contact with the outlet end 320. It can be understood that when the outlet end 320 of the pin 30 is in contact with the inner arc surface of the first arc segment 4110, the first arc segment 4110 will be elastically deformed to a certain extent to ensure that the outlet end 320 and the first arc segment 4110 are tightly fitted. At this time, the first arc segment 4110 will bend in a direction away from its center. When the outlet end 320 of the pin 30 is away from the first arc segment 4110, the first arc segment 4110 will adaptively restore to its initial state. At this time, the first arc segment 4110 will bend in a direction close to its center. When the protruding end 320 of the pin 30 abuts against the inner arc surface of the second arc segment 4130, the second arc segment 4130 will be elastically deformed to a certain extent to ensure that the protruding end 320 and the second arc segment 4130 are tightly fitted. At this time, the second arc segment 4130 will bend in a direction away from its center. When the protruding end 320 of the pin 30 is away from the second arc segment 4130, the second arc segment 4130 will adaptively return to its initial state. At this time, the second arc segment 4130 will bend in a direction close to its center.

[0065] In some embodiments, the first arc segment 4110 and the second arc segment 4130 themselves may not be elastic, and it is sufficient to ensure that the curvature of the first arc segment 4110 and the second arc segment 4130 can just fit the protruding end 320 .

[0066] like Figure 7 and Figure 8 As shown, in some embodiments, the first abutment portion 410 is an elastic abutment portion. The first abutment portion 410 is configured to drive the pin 30 to rotate after the pin 30 is driven by an external force and rotates to a first preset angle, so that the pin 30 switches from the first state to the second state. The first abutment portion 410 is also configured to drive the pin 30 to rotate after the pin 30 is driven by an external force and rotates to a second preset angle, so that the pin 30 switches from the second state to the first state.

[0067] It is understandable that the pin 30 switches between the first state and the second state by rotating. When the pin 30 switches between the first state and the second state, the pin 30 and the rotating member 20 need to rotate 90 degrees. When the pin 30 needs to switch from the first state to the second state, the pin 30 can be rotated by a first preset angle under the action of an external force. Then the external force can be cancelled, and the pin 30 can be driven to rotate subsequently by the elasticity of the first abutting portion 410 itself. When the pin 30 needs to switch from the second state to the first state, the pin 30 can be rotated by a second preset angle under the action of an external force. Then the external force can be cancelled, and the pin 30 can be driven to rotate subsequently by the elasticity of the first abutting portion 410 itself. In this way, the state switching of the pin 30 is easily achieved.

[0068] In some embodiments, when the plug pin 30 rotates to a first preset angle under the action of an external force, the outlet end 320 of the plug pin 30 will gradually move away from the first arc segment 4110, and the first arc segment 4110 will recover from the deformed state to the initial state, and the first arc segment 4110 will recover its deformation in the direction close to its center. If the force exerted by the first arc segment 4110 on the first connection portion 310 is greater than the resistance to the rotation of the plug pin 30 (the resistance includes the force exerted by the first oblique segment 4120 on the first connection portion 310, the rotation friction of the rotating member 20, etc.), the first arc segment 4110 can push the first connection portion 310 to rotate, thereby realizing the state switching of the plug pin 30. And / or, when the first connection portion 310 rotates to a position corresponding to the first oblique segment 4120, the outlet end 320 of the first connection portion 310 is in a pressing relationship with the first oblique segment 4120. At this time, the first oblique segment 4120 is in an elastic deformation state. When the external force is removed, if the force exerted by the first oblique section 4120 on the first connecting portion 310 is greater than the resistance encountered by the pin 30 in rotating (the resistance encountered includes the force exerted by the second arc section 4130 on the first connecting portion 310, the rotational friction of the rotating member 20, etc.), the first oblique section 4120 can push the first connecting portion 310 to rotate, thereby realizing the state switching of the pin 30.

[0069] In some embodiments, the first preset angle can be set to 15 to 60 degrees. For example, the first preset angle is set to 15 degrees, 30 degrees, 45 degrees, 60 degrees, or any value between the two. The first preset angle will change based on the material of the first abutment portion 410. The first preset angle will also change based on the curvature of the first arc segment 4110, the curvature of the second arc segment 4130, and the inclination angle of the first oblique segment 4120. The first preset angle will also change based on the arc length of the first arc segment 4110, the arc length of the second arc segment 4130, and the length of the first oblique segment 4120. The present application does not limit the above-mentioned change relationship. When designing, it is sufficient to ensure that the first abutment portion 410 can drive the pin 30 to continue rotating after the pin 30 rotates a certain angle.

[0070] In some embodiments, when the plug pin 30 rotates to a second preset angle under the action of an external force, the outlet end 320 of the plug pin 30 will gradually move away from the second arc segment 4130, and the second arc segment 4130 will recover from the deformed state to the initial state, and the second arc segment 4130 will recover the deformation in the direction close to the center of the circle. If the force exerted by the second arc segment 4130 on the first connection portion 310 is greater than the resistance to the rotation of the plug pin 30 (the resistance includes the force exerted by the first oblique segment 4120 on the first connection portion 310, the rotation friction of the rotating member 20, etc.), the second arc segment 4130 can push the first connection portion 310 to rotate, thereby realizing the state switching of the plug pin 30. And / or, when the first connection portion 310 rotates to a position corresponding to the first oblique segment 4120, the outlet end 320 of the first connection portion 310 is in a pressing relationship with the first oblique segment 4120. At this time, the first oblique segment 4120 is in an elastic deformation state. When the external force is removed, if the force exerted by the first oblique section 4120 on the first connecting part 310 is greater than the resistance encountered by the pin 30 in rotating (the resistance encountered includes the force exerted by the first arc section 4110 on the first connecting part 310, the rotational friction of the rotating member 20, etc.), the first oblique section 4120 can push the first connecting part 310 to rotate, thereby realizing the state switching of the pin 30.

[0071] In some embodiments, the second preset angle can be set to 15 to 60 degrees. For example, the second preset angle is set to 15 degrees, 30 degrees, 45 degrees, 60 degrees, or any value between the two. The second preset angle will change based on the material of the first abutment portion 410. The second preset angle will also change based on the curvature of the first arc segment 4110, the curvature of the second arc segment 4130, and the inclination angle of the first oblique segment 4120. The second preset angle will also change based on the arc length of the first arc segment 4110, the arc length of the second arc segment 4130, and the length of the first oblique segment 4120. The present application does not limit the above-mentioned change relationship. When designing, it is sufficient to ensure that the first abutment portion 410 can drive the pin 30 to continue rotating after the pin 30 rotates a certain angle.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the second abutting portion 420 includes a second oblique section 4210 and a third arc section 4220. One end of the second oblique section 4210 is connected to the spring 40, and the other end is connected to the third arc section 4220. The third arc section 4220 abuts against the outer peripheral surface of the conductive member 50 and is electrically connected.

[0073] It can be understood that the second abutting portion 420 abuts against the outer circumference of the conductive member 50 through the third arc segment 4220 and is electrically connected. No matter what rotation angle the plug pin 30 and the rotating member 20 are at, the third arc segment 4220 can contact the outer circumference of the conductive portion to ensure reliable electrical connection between the spring 40 and the plug pin 30. The electrical transmission path is: spring 40-second oblique segment 4210-third arc segment 4220-conductive member 50-plug pin 30.

[0074] In some embodiments, the third arc segment 4220 and the second oblique segment 4210 both have a certain elasticity, so that the third arc segment 4220 can be pressed against the outer peripheral surface of the conductive member 50 with a certain force, thereby ensuring reliable electrical connection between the two.

[0075] In some embodiments, the third arc segment 4220 and the second oblique segment 4210 may not have elasticity, as long as the third arc segment 4220 can fit the outer circumference of the conductive element 50 .

[0076] like Figure 4 and Figure 6 As shown, in some embodiments, the conductive member 50 includes a first contact portion 510. The first contact portion 510 is set to be cylindrical. The radius of the first contact portion 510 is R1. The radius of the third arc segment 4220 is R2. The third arc segment 4220 is set to be co-centered with the first contact portion 510, and satisfies: R1≥R2.

[0077] It is understandable that the radius R2 of the third arc segment 4220 is less than or equal to the radius R1 of the first contact portion 510 to ensure that the third arc segment 4220 can reliably abut against the first contact portion 510. In the embodiment of the present application, it is preferred that the radius R2 of the third arc segment 4220 is less than the radius R1 of the first contact portion 510. Thus, the third arc segment 4220 can be pressed against the outer peripheral surface of the conductive member 50 with a certain force, thereby ensuring that the two are reliably electrically connected.

[0078] like Figure 4 and Figure 6 As shown, in some embodiments, the conductive member 50 further includes a second contact portion 520 coaxially arranged with the first contact portion 510. The second abutting portion 420 further includes a bent portion 4230. The bent portion 4230 is connected to the second oblique section 4210 and is bent toward the second contact portion 520. The bent portion 4230 abuts against the second contact portion 520 and is electrically connected.

[0079] It is understandable that, by the bending portion 4230 abutting against the second contact portion 520 and being electrically connected, the second abutting portion 420 has two contact points electrically connected to the conductive member 50. This can further increase the contact area, reduce the contact impedance, and improve the output power.

[0080] The bending portion 4230 has a certain area to ensure that the bending portion 4230 can abut against the second contact portion 520 and be electrically connected in both the first state and the second state. Alternatively, the second contact portion 520 can be set to a hemispherical shape. The bending portion 4230 is perpendicular to the central axis of the hemisphere and abuts against the outer surface of the hemisphere. Thus, it can also be ensured that the bending portion 4230 can abut against the second contact portion 520 and be electrically connected in both the first state and the second state.

[0081] In some embodiments, the second contact portion 520 is integrally formed with the first contact portion 510 .

[0082] In some embodiments, the pin 30 has a first state and a second state. The second abutment portion 420 is an elastic abutment portion. The second abutment portion 420 is configured to drive the pin 30 to rotate after the pin 30 is driven by an external force and rotates to a first preset angle, so that the pin 30 switches from the first state to the second state. The second abutment portion 420 is also configured to drive the pin 30 to rotate after the pin 30 is driven by an external force and rotates to a second preset angle, so that the pin 30 switches from the second state to the first state.

[0083] It is understandable that the pin 30 switches between the first state and the second state by rotating. When the pin 30 switches between the first state and the second state, the pin 30 and the rotating member 20 need to rotate 90 degrees. When the pin 30 needs to switch from the first state to the second state, the pin 30 can be rotated by a first preset angle under the action of an external force. Then the external force can be cancelled, and the pin 30 can be driven to rotate subsequently by the elasticity of the second abutting portion 420 itself. When the pin 30 needs to switch from the second state to the first state, the pin 30 can be rotated by a second preset angle under the action of an external force. Then the external force can be cancelled, and the pin 30 can be driven to rotate subsequently by the elasticity of the second abutting portion 420 itself. In this way, the state switching of the pin 30 is easily realized.

[0084] At this time, the structure of the second abutting portion 420 can be similar to that of the first abutting portion 410. For example, the third arc segment 4220 is set to be two at intervals, namely, segment A and segment B. At the same time, an eccentric portion protruding outward can be set on the peripheral side of the first contact portion 510. In the first state, the eccentric portion abuts against segment A. In the second state, the eccentric portion abuts against segment B. When segment A abuts against the eccentric portion, segment A is deformed so that it bends in a direction away from the circle. When segment B abuts against the eccentric portion, segment B is deformed so that it bends in a direction away from the circle. Among them, segment A will recover from the deformation state to the initial state and will recover the deformation in the direction close to its center of the circle. If the force of segment A on the eccentric portion is greater than the resistance to the rotation of the pin 30 (the resistance includes the rotation friction of the rotating member 20, etc.), segment A can push the eccentric portion to rotate, thereby driving the rotating member 20 and the pin 30 to rotate. And / or, when segment B recovers from the deformed state to the initial state, it will recover its deformation in the direction close to its center. If the force exerted by segment B on the eccentric part is greater than the resistance encountered by the pin 30 in rotating (the resistance encountered includes the rotational friction of the rotating member 20, etc.), segment B can push the eccentric part to rotate, thereby driving the rotating member 20 and the pin 30 to rotate.

[0085] Among them, the first preset angle and the second preset angle in this embodiment can be the same as the values ​​of the first preset angle and the second preset angle in the aforementioned embodiment, and will not be repeated here.

[0086] like Fig.10 and Fig.11 As shown, in some embodiments, the pin 30 further includes a second connection portion 330. The second connection portion 330 and the first connection portion 310 are located at the same end of the pin 30 and are spaced apart. The rotating member 20 is formed with a mounting groove 220. The second connection portion 330 is snapped into the mounting groove 220.

[0087] It is understandable that the second connection portion 330 of the pin 30 is snapped into the mounting groove 220 to cooperate with the first connection portion 310 to achieve a reliable connection with the rotating member 20. At the same time, it is ensured that the pin 30 and the rotating member 20 are relatively fixed and do not rotate relative to each other.

[0088] The second connection portion 330 is shorter than the first connection portion 310 .

[0089] In some embodiments, the second connection portion 330 is configured to abut against and be electrically connected to the first abutting portion 410 .

[0090] Specifically, when the plug pin 30 is in the first state, the second connection portion 330 abuts against and is electrically connected to the second arc segment 4130 of the first abutting portion 410. Thus, when the plug pin 30 is in the first state, on the one hand, the first connection portion 310 can abut against and be electrically connected to the first arc segment 4110 of the first abutting portion 410, and on the other hand, the second connection portion 330 can abut against and be electrically connected to the second arc segment 4130 of the first abutting portion 410. Thus, in the first state, the plug pin 30 forms multiple contact points with the first abutting portion 410, ensuring reliable electrical connection between the two.

[0091] In some embodiments, a circuit board is disposed on the base 10. The spring 40 is electrically connected to the circuit board.

[0092] It is understandable that the electrical connection between the spring 40 and the pin 30 is ultimately required to realize electrical transmission between the power supply and the circuit board or between the circuit boards. Therefore, the spring 40 is electrically connected to the circuit board to realize its function.

[0093] The circuit board may be a PCB (Printed Circuit Board). The circuit board may also be an FPC (Flexible Printed Circuit). The circuit board may be reasonably selected based on the type of power adapter and usage requirements.

[0094] In some embodiments, the spring piece 40 can be directly fixed on the circuit board. For example, the spring piece 40 is installed on the threaded hole of the circuit board by a metal screw to achieve the fixation and electrical connection between the spring piece 40 and the circuit board.

[0095] In some embodiments, the spring sheet 40 is also connected to a conductive wire. The spring sheet 40 is electrically connected to the circuit board through the conductive wire. At this time, the spring sheet 40 is electrically connected to the circuit board through the conductive wire. The spring sheet 40 can be fixed to the base 10 by a fastener. At least two abutment portions are provided at one end of the spring sheet 40, and the other end of the spring sheet 40 is connected to the conductive wire.

[0096] For example, the conductive wire can be a copper wire, and an insulating layer is provided on the outside of the copper wire. One end of the copper wire is soldered to the spring 40, and the other end of the copper wire is soldered to the circuit board.

[0097] The embodiment of the present application further provides a power adapter, which includes the electrical connection structure in the above embodiment.

[0098] In the embodiment of the present application, at least two abutting portions are connected to the spring sheet 40, so that the at least two abutting portions are electrically connected to different regions of the pin 30. Thus, at least two contact points can be provided between the pin 30 and the spring sheet 40, thereby increasing the contact area, reducing the contact impedance, and improving the output power. At the same time, based on the redundant setting of the contact points, when the electrical connection at one of the contact points is disconnected, the remaining contact points can ensure a reliable electrical connection between the pin 30 and the spring sheet 40, which can improve the fault tolerance of the electrical connection between the pin 30 and the spring sheet 40.

[0099] The embodiment of the present application further provides an electronic device, which includes a power adapter as described in the above embodiment.

[0100] In the embodiment of the present application, at least two abutting portions are connected to the spring sheet 40, so that the at least two abutting portions are electrically connected to different regions of the pin 30. Thus, at least two contact points can be provided between the pin 30 and the spring sheet 40, thereby increasing the contact area, reducing the contact impedance, and improving the output power. At the same time, based on the redundant setting of the contact points, when the electrical connection at one of the contact points is disconnected, the remaining contact points can ensure a reliable electrical connection between the pin 30 and the spring sheet 40, which can improve the fault tolerance of the electrical connection between the pin 30 and the spring sheet 40.
