FIG. 4 is a schematic three-dimensional view of the power supply device 10 before assembly according to an embodiment of the present invention. FIG. 5A is a schematic three-dimensional view of the power supply device 10 during assembly according to an embodiment of the present invention. Figure 5B is a schematic perspective view of the power supply device 10 during assembly in Figure 5A, looking from a bottom-up perspective. FIG. 6A is a schematic three-dimensional view of the assembled power supply device 10 according to an embodiment of the present invention. Figure 6B is a schematic perspective view of the assembled power supply device 10 of Figure 6A, looking from the bottom up. In order to facilitate understanding of the component action relationships of the power supply device during the assembly process, the lower case 201, the circuit board 203, the base bottom plate 225 and the bottom plate 143 are not shown in Figures 5B and 6B. During the assembly process of the power supply device shown in Figure 4-6B, the pins 102 protrude out of the groove 111 (expanded position), but the present invention is not limited to this. The pins 102 can also be accommodated in the groove 111 (retracted position). fold position) for assembly. Alternatively, the pins 102 may switch between the deployed and collapsed positions during assembly.

First, position the plurality of positioning bumps 145 of the plug 100 corresponding to the position of the positioning groove 223, and the plug 100 moves toward the body 200 (for example, along the arrow direction in Figure 4), so that a part of the plug 100 is located in the assembly part 226, The plug 100 is located on the body 200, as shown in Figure 5A. At this time, the plug 100 is located at the first position relative to the body 200 . As shown in Figures 5A-5B, when the plug 100 is in the first position, the plug 100 and the body 200 are staggered. The side plate 142 and the bottom plate 143 of the plug 100 may be disposed in the assembly area 221 of the assembly part 226 . The positioning protrusion 145 of the plug 100 can be disposed in the positioning groove 223 of the assembly part 226 . The plate body 141 of the plug 100 (please refer to Figures 2A-2B) can be disposed on the base plate body 220 of the body 200. The lever 215 is at least partially disposed in the sliding track 230-1 and extends into the through hole 228-1. The front end 215E of the lever 215 protrudes from the base side plate 224 and is located in the arc-shaped assembly chute 222 of the assembly portion 226. The conductive pins 212 are at least partially disposed in the sliding track 230-2 and extend into the through holes 228-2. At this time, the conductive pins 212 are in the storage position. The elastic member 213 supports the connecting rod 214 so that the conductive pin 212 can be maintained in the stowed position. When the conductive pin 212 is in the stowed position, the conductive pin 212 is electrically isolated from the pin 102 . In one embodiment, when the conductive pins 212 are in the stowed position, the front ends 212E of the conductive pins 212 may slightly protrude from the base side panel 224 , and the conductive pins 212 do not contact the plug 100 . In another embodiment, when the conductive pin 212 is in the stowed position, the front end 212E of the conductive pin 212 can be completely accommodated. In the through hole 228 - 2 , the front end 212E of the conductive pin 212 may not protrude from the base side plate 224 , and the conductive pin 212 may not contact the plug 100 .

Next, the plug 100 is rotated relative to the body 200 . In one embodiment, the plug 100 can be rotated relative to the body 200 by an angle not greater than 90 degrees, for example, by an angle not greater than 60±10 degrees. The stopper 227 can limit the rotation direction of the plug 100 so that the plug 100 can only rotate in the counterclockwise direction in Figure 5B. During the rotation of the plug 100, the positioning protrusion 145 of the plug 100 slides from the corresponding positioning groove 223 into the arc-shaped assembly chute 222 connected with the positioning groove 223. When the positioning protrusion 145 of the plug 100 is located in the arc-shaped assembly chute 222, the limiting wall 229 (please refer to Figure 3B) can limit the displacement of the plug 100 in the vertical direction. The plug 100 rotates along the arc-shaped assembly chute 222 so that the positioning bump 145 contacts the lever 215 and pushes the lever 215 outward. The lever 215 drives the conductive pins 212 through the connecting rod 214, so that the conductive pins 212 move along the The sliding track 230 - 2 moves toward the side plate 142 of the plug 100 .

The plug 100 can be rotated to a second position relative to the body 200, as shown in Figures 6A-6B. When the plug 100 is in the second position, the through hole 146 of the plug 100 may roughly correspond to the position of the conductive pin 212. The front end 212E of the conductive pin 212 protrudes from the base side plate 224, and the conductive pin 212 passes through the through hole 146. The front end 212E of the conductive pin 212 contacts the first extension piece 132 of the conductive member 103 of the plug 100, so that the plug 100 and the body 200 are electrically connected. At this time, the conductive pin 212 is in the extended position. The pins 102 of the plug 100 are electrically connected to the circuit board 203 through the conductive element 103 and the conductive pins 212 . Current from the external power supply can be supplied via pin 102, The conductive component 103 , the conductive pins 212 , and the circuit board 203 are transmitted to the electrical product or battery connected to the power supply device 10 . When the plug 100 is in the second position, the connecting rod 214 exerts a force on the elastic member 213 toward the plug 100 to deform the elastic member 213 . In one embodiment, when the plug 100 is in the second position, the plug 100 and the body 200 may be aligned with each other. In one embodiment, when the plug 100 is in the second position, the plug 100 and the body 200 can interfere with each other and be fixed. At this time, the displacement of the plug 100 in both the horizontal direction and the vertical direction is limited. The plug 100 may be of any plug standard, such as the United States, the United Kingdom, the European Union, Australia, Japan, Mainland China or South Korea. In other words, these plugs 100 with different plug specifications can all use the conductive pins 212 of the present invention, that is, the pins 102 of the plugs 100 with different specifications can be electrically connected to the circuit board 203 through the conductive element 103 and the conductive pins 212 . Therefore, the manufacturing cost of the power supply device 10 can be effectively reduced and it is easy to use.

At this point, the plug 100 has been assembled on the body 200, and the assembly of the power supply device 10 is completed.

In one embodiment, the plug 100 can be rotated from the second position to the first position to remove or replace the plug 100 . When the plug 100 returns to the first position from the second position, the force exerted by the positioning bump 145 on the lever 215 is released, the elastic member 213 recovers from the deformed state, and the conductive pins 212 automatically return to the storage position.

The present invention provides a power supply device including movable conductive pins. The conductive pins are located in a storage position when the plug is not assembled in the body, and are located in an extended position to form an electrical connection when the plug is assembled in the body. Through such a configuration, the exposed area of the conductive pins can be reduced or the exposed conductive pins can be avoided, thereby improving conductivity. The electrical pins are prone to rust, deformation or cracking, and can improve the electrical connection quality and service life of the power supply device. In addition, the conductive pins of the present invention can be applied to plugs with different plug specifications, which can reduce the manufacturing cost of the power supply device and facilitate users to use it in countries around the world.

In summary, although the present invention has been disclosed above through embodiments, they are not intended to limit the present invention. Those with ordinary knowledge in the technical field to which the present invention belongs can make various modifications and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the appended patent application scope.
