[0040] Example

[0041] This embodiment provides a foldable British standard plug, which is a three-pin plug that complies with British standards. Figures 1-9The foldable UK-standard plug provided in this embodiment includes: a first prong 1, one end of which is provided with a first connecting shaft 101; and a connecting rod 2, which specifically includes a connecting rod body 201, with a first connecting portion 202 and a second connecting portion 203 connected at both ends of the connecting rod body 201, respectively. The lengths of the first connecting portion 202 and the second connecting portion 203 are arranged perpendicular to the length of the connecting rod body 201, thereby forming a door-shaped connecting rod 2. The first connecting shaft 101 has two ends connected to the ends of the first connecting portion 202 and the second connecting portion 203, respectively, away from the connecting rod body 201; the end of the first connecting portion 202 closer to the connecting rod body 201 is connected to the second prong 3, and the end of the second connecting portion 203 closer to the connecting rod body 201 is connected to the third prong 4. The plug further includes a first housing 5, which is provided with a first receiving slot 501, a second receiving slot 502, and a third receiving slot 503 corresponding to the positions of the first pin 1, the second pin 3, and the third pin 4, respectively. Furthermore, openings are provided within the first receiving slot 501, the second receiving slot 502, and the third receiving slot 503 for allowing the first pin 1, the second pin 3, and the third pin 4 to extend from the first housing 5. The openings extend through the first housing 5, allowing the first pin 1, the second pin 3, and the third pin 4 to connect to a circuit board or other structure within the plug. The first pin 1 can rotate relative to the first housing 5 and, via the connecting rod 2, drive the second pin 3 and the third pin 4 to rotate in the opposite direction, thereby forming a first state in which the first pin 1, the second pin 3, and the third pin 4 are respectively accommodated in the first receiving slot 501, the second receiving slot 502, and the third receiving slot 503, and a second state in which the first pin 1, the second receiving slot 502, and the third receiving slot 503 are flipped and extended.

[0042] By providing a connecting rod 2, and connecting the first pin 1 at one end of the connecting rod 2, and connecting the second pin 3 and the third pin 4 at the other end of the connecting rod 2, the first pin 1, the second pin 3 and the third pin 4 can perform a connecting rod movement synchronously. Specifically, when the first pin 1 rotates, it drives the first connecting shaft 101 to rotate. The rotation of the first connecting shaft 101 drives the second pin 3 and the third pin 4 to rotate in the opposite direction through the connecting rod 2, so that the first pin 1, the second pin 3 and the third pin 4 are moved from the first receiving groove 501 and the second receiving groove 50 2 and the third receiving groove 503, or the first pin 1, the second pin 3 and the third pin 4 are flipped from the extended state and accommodated in the first receiving groove 501, the second receiving groove 502 and the third receiving groove 503 respectively, forming a foldable British standard plug. When it is necessary to charge the electronic device, the three pins are flipped out of the first shell 5 and inserted into the socket. When carrying or storing, the three pins are accommodated in the receiving grooves, making the plug compact and smooth, and more portable. At the same time, the above-mentioned flip structure is simple and easy to produce.

[0043] In this embodiment, the first pin 1 , the second pin 3 , and the third pin 4 can be configured as a live pin, a neutral pin, or a ground pin according to actual needs or British standards.

[0044] See also Figure 3 The end of the second pin 3 near the connecting rod body 201 is connected to a first spring piece 6. One end of the first spring piece 6 is connected to the end of the second pin 3, and the other end extends along the length of the second pin 3, with the extended portion spaced apart from the second pin 3. The end of the third pin 4 near the connecting rod body 201 is connected to a second spring piece 7. One end of the second spring piece 7 is connected to the end of the third pin 4, and the other end extends along the length of the third pin 4, with the extended portion spaced apart from the third pin 4.

[0045] In this embodiment, the first spring piece 6 and the second spring piece 7 are both metal spring pieces. On the one hand, they play a conductive role. On the other hand, their elastic structure provides an elastic force for the flipping of the second pin 3 and the third pin 4, so that the second pin 3 and the third pin 4 form a critical point when they are rotated to 45°. At this angle, the elastic force of the first spring piece 6 and the second spring piece 7 provides a flipping assist, which makes the subsequent flipping process smoother and more labor-saving.

[0046] Specifically, the first spring piece 6 and the second spring piece 7 are in a mirror-symmetrical relationship. As shown in the figure, in this embodiment, the first spring piece 6 is taken as an example for specific description, which includes a connecting portion 601. The connecting portion 601 has an arc-shaped structure and is fixedly connected to the end of the second pin 3. The connecting portion 601 is connected to an extension portion 602. The extension portion 602 extends to the second pin 3 and is spaced apart from the second pin 3. In this way, the bent connecting portion 601 and the extension portion 602 can be deformed and then generate elastic force under the action of external force. A folding portion 603 is vertically connected to one side of the extension portion 602. The folding portion 603 is used to connect with the metal sheet extending from the main body of the circuit board (not shown in the figure) in the plug to play a conductive role. The circuit board is used to convert voltage.

[0047] In order to fix the first elastic piece 6 and the second elastic piece 7, an elastic piece fixing seat 8 is also included. Figure 5-7 As shown, the spring retainer 8 has internal space for mounting the first spring 6, second spring 7, connecting rod 2, and plug pins. The spring retainer 8 is fixedly connected to the first housing 5 via connectors 9. In this embodiment, connectors 9 are preferably set screws. Specifically, the spring retainer 8 is connected to the first housing 5 via four set screws around its perimeter, thereby ensuring a secure plug housing structure. The inner bottom wall of the spring retainer 8 abuts against the extensions of the first and second spring 6 and 7 springs.

[0048] The end of the spring clip holder 8 away from the first housing 5 is also connected to a second housing 10. The first housing 5, spring clip holder 8, and second housing 10 are sequentially connected to form the main housing structure of the plug. To accommodate other components, a first mounting cavity 11 is formed between the spring clip holder 8 and the first housing 5. The connecting rod 2, connected to the first pin 1, the second pin 3, and the third pin 4, is installed in this first mounting cavity 11. A second mounting cavity 12 is formed between the spring clip holder 8 and the second housing 10. The first and second spring clips 6 and 7 extend through the inner bottom wall of the spring clip holder 8 and are accommodated in the second mounting cavity 12. Specifically, the folded portions of the first and second spring clips 6 and 7 extend through the inner bottom wall of the holder 8 and into the second mounting cavity 12.

[0049] To separate the first mounting cavity 11 and the second mounting cavity 12, a mounting plate 801 is provided within the spring clip holder 8. The sidewalls of the spring clip holder 8, the mounting plate 801, and the first cover 5 enclose the first mounting cavity 11, while the sidewalls of the spring clip holder 8, the mounting plate 801, and the second cover 10 enclose the second mounting cavity 12. An opening 802 is defined on the side of the mounting plate 801 near the first connecting shaft 101. A stopper 803 is connected to the opening 802. As shown in the figure, the stopper 803 has an arc-shaped cross-section, with one end connected to the edge of the opening 802 and the other end being free. When the first pin 1 rotates 90°, the stopper 803 stops the first pin 1 and positions it, preventing it from rotating too far. In order to allow the folded parts of the first and second spring pieces 6 and 7 to pass through the fixing seat 8, the mounting plate 801 is provided with an avoidance groove, which is a through groove. The folded parts of the first and second spring pieces 6 and 7 extend through the avoidance groove to the second mounting cavity 12.

[0050] A first connecting slot 804 and a second connecting slot 805 are symmetrically disposed on either side of the opening 802. A first rotating shaft 102 is disposed on the end of the first pin 1 closest to the first connecting axis 101. The ends of the first rotating shaft 102 are respectively connected to the first connecting slot 804 and the second connecting slot 805. To prevent the first rotating shaft 102 from dislodging from the first connecting slot 804 and the second connecting slot 805 when the first pin 1 rotates, the first housing 5 is provided with a third connecting slot 504 and a fourth connecting slot 505 corresponding to the first connecting slot 804 and the second connecting slot 805. One end of the first rotating shaft 102 fits between the first connecting slot 804 and the third connecting slot 504, while the other end fits between the second connecting slot 805 and the fourth connecting slot 505.

[0051] A second rotating shaft 302 is provided at one end of the second pin 3 close to the second connecting shaft 301. A first supporting portion 806 is provided on the mounting plate 801 at a position corresponding to the second rotating shaft 302. The first supporting portion 806 is protruded from the surface of the mounting plate 801 for supporting the second rotating shaft 302, and a concave area is formed on the top of the first supporting portion 806 to accommodate the second rotating shaft 302. A fifth connecting groove is provided on the first housing 5 at a position corresponding to the first supporting portion 806. One end of the second rotating shaft 302 is adapted to be accommodated between the first supporting portion 806 and the fifth connecting groove. A third rotating shaft 402 is provided at one end of the third pin 4 close to the third connecting shaft 401, and a second bearing portion 807 is provided at a position of the mounting plate 801 corresponding to the third rotating shaft 402. The second bearing portion 807 is protruded from the plate surface of the mounting plate 801 for supporting the third rotating shaft 402. The top of the second bearing portion 807 has a concave area to accommodate the third rotating shaft 402. A sixth connecting groove is provided at a position of the first housing 5 corresponding to the second bearing portion 807, and one end of the third rotating shaft 402 is adapted to be accommodated between the second bearing portion 807 and the sixth connecting groove.

[0052] Furthermore, in order to fix the first spring clip 6 and the second spring clip 7, the extension parts of the first spring clip 6 and the second spring clip 7 are provided with connecting through holes. Taking the first spring clip 6 as an example, two connecting through holes 604 are provided on the extension part 602 at intervals. Correspondingly, two connecting columns 506 are protruding from the first shell 5, and the connecting columns 506 are adapted to be connected to the connecting through holes 604 to fix the spring clips.

[0053] To make the plug's overall structure more compact, the side of the spring retainer 8 near the second housing 10 features a stepped portion 808. This stepped portion 808 is formed by a horizontal portion parallel to the second housing 10 and a vertical sidewall perpendicular to the horizontal portion. At least one plug port 809 is provided on the sidewall. This plug port 809 connects to the circuit board inside the plug to connect it to an external power source. The plug port 809 can be a USB port or a Type-C port, depending on the requirements. In this embodiment, there are at least two plug ports 809, enabling charging of at least two electronic devices. By placing the plug ports 809 on the sidewall of the stepped portion 808, the structure is more compact and provides a certain degree of protection compared to conventional methods where the plug ports are located on the surface of the plug.

[0054] In addition, the cross-sectional shapes of the spring fixing seat 8, the first shell 5, and the second shell 10 are all regular hexagons, making the overall shape of the plug more novel and beautiful.

[0055] The foldable British standard plug provided in this embodiment is assembled as follows: first, the first pin 1 is connected to one end of the connecting rod 2, and then the second pin 3 and the third pin 4 are respectively connected to the other end of the connecting rod 2, and the assembled pin assembly is installed on the first shell 5. The first spring clip 6 and the second spring clip 7 are respectively installed on the second pin 3 and the third pin 4, and the spring clip fixing seat 8 is installed. The spring clip fixing seat 8 is fixed to the first shell 5 with screws, and finally the second shell 10 is assembled.

[0056] During use, the first pin 1 can be pulled to rotate relative to the first housing 5. The rotation of the first pin 1 causes the second pin 3 and the third pin 4 to synchronously move the connecting rod through the connecting rod 2 and rotate in the opposite direction of the first pin 1. The first pin 1, the second pin 2, and the third pin 3 are stopped after rotating 90°, thereby forming an angle perpendicular to the first housing 5, so as to facilitate insertion into the charging socket for use.

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
