Folding socket

[0001] The present application claims priority to the Chinese patent application No. 2024218017468, filed on July 26, 2024, and entitled "Folding socket", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of socket, in particular to a folding socket. BACKGROUND

[0003] Socket is an essential tool in people's life, which can provide great convenience for people to use electric energy.

[0004] When people are camping or other outdoor activities, they may carry a mobile power supply and a socket based on the need for electricity. However, since the depth of the socket needs to meet the relevant regulations, the thickness of the socket is often greater than the depth of the socket, so the thickness of the socket is often thick and not convenient to carry. SUMMARY

[0005] The present application provides a folding socket, which can solve the problem of large thickness of the socket.

[0006] The present application provides a folding socket, comprising: a shell, a first module and a second module, the first module is hinged to the shell and has a first position and a second position in the rotating direction, and a first socket is arranged on the first module; the second module is hinged to the shell and has a third position and a fourth position in the rotating direction, and a second socket is arranged on the second module; wherein the folding socket has an unfolded state and a storage state, when the folding socket is in the unfolded state, the first module is located at the first position, the second module is located at the third position, the first socket and the second socket are oriented in the same direction, and the first socket and the second socket together form a two-pronged socket or a three-pronged socket; when the folding socket is in the storage state, the first module is located at the second position, the second module is located at the fourth position, and the first socket and the second socket are oriented in opposite directions.

[0007] The folding socket of the present application can rotate the first module and the second module relative to the shell, so that the folding socket has an unfolded state and a storage state. In the unfolded state, the first socket and the second socket can be arranged to supply power to the electric appliance. When power supply to the electric appliance is not needed, the first module and the second module are rotated and stored. By rotating the first module and the second module, the thickness of the folding socket is thinner in the storage state, effectively solving the problem of large thickness of the socket.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0020] The folding socket 200 of the present application will be described below with reference to FIGS. 1 to 5.

[0021] Referring to FIGS. 1 to 5, the folding socket 200 according to the embodiments of the present application includes a housing 1, a first module 2 and a second module 3. The first module 2 is hingedly connected to the housing 1 and has a first position and a second position in the rotating direction, and the first module 2 is provided with a first socket 21. The second module 3 is hingedly connected to the housing 1 and has a third position and a fourth position in the rotating direction, and the second module 3 is provided with a second socket 31. The folding socket 200 has an unfolded state and a storage state, as shown in FIGS. 1 to 4. When the folding socket 200 is in the unfolded state, the first module 2 is located at the first position, the second module 3 is located at the third position, and the first socket 21 and the second socket 31 are oriented in the same direction. As shown in FIG. 5, when the folding socket 200 is in the storage state, the first module 2 is located at the second position, the second module 3 is located at the fourth position, and the first socket 21 and the second socket 31 are oriented in opposite directions.

[0022] Specifically, the housing 1 can have a flat structure, and the upper and lower end faces thereof can be flat, so that the thickness of the housing 1 is thinner and the aesthetic appearance is better.

[0023] The first socket 21 and the second socket 31 are configured to be plugged with the plug of the electrical appliance, and in the unfolded state, the first socket 21 and the second socket 31 are oriented in the same direction, and the plug of the electrical appliance can be plugged into the first socket 21 and the second socket 31, so that the electrical appliance obtains electricity. The first socket 21 can be part of a conventional socket (for example, a three-pin socket or a two-pin socket, etc.), and the second socket 31 is another part of the conventional socket. In the unfolded state, the plug of the electrical appliance is plugged into the first socket 21 and the second socket 31, and when the electrical appliance does not need to be powered, the first module 2 is flipped to the second position, and the second module 3 is flipped to the fourth position, so that the first module 2 and the second module 3 are stored. Since the depth of the socket needs to meet the industry standard, this makes the thickness of the socket larger, and by rotating the first module 2 and the second module 3, the depth direction of the first socket 21 and the second socket 31 can be changed, which helps to reduce the thickness of the first module 2 and the second module 3 in the storage state.

[0024] For example, the first module 2 is part of a three-pin socket module, the first socket 21 is part of a three-pin socket, the second module 3 is another part of the three-pin socket module, and the second socket 31 is another part of the three-pin socket. In the unfolded state, the first socket 21 and the second socket 31 are oriented in the same direction, the first module 2 and the second module 3 together form a three-pin socket module, the first socket 21 and the second socket 31 together form a three-pin socket, and a three-pin plug of the electrical appliance can be plugged into the first socket 21 and the second socket 31 at the same time to obtain electricity; when the electrical appliance does not need to be powered, the first module 2 and the second module 3 are respectively rotated and stored, so that the thickness of the folding socket 200 in the storage state is lower.

[0025] Alternatively, the first module 2 is part of a two-pin socket module, the first socket 21 is part of a two-pin socket, the second module 3 is another part of the two-pin socket module, and the second socket 31 is another part of the two-pin socket. In the unfolded state, the first socket 21 and the second socket 31 are oriented in the same direction, the first module 2 and the second module 3 together form a two-pin socket module, the first socket 21 and the second socket 31 together form a two-pin socket, and a two-pin plug of the electrical appliance can be plugged into the first socket 21 and the second socket 31 at the same time to obtain electricity; when the electrical appliance does not need to be powered, the first module 2 and the second module 3 are respectively rotated and stored, so that the thickness of the folding socket 200 in the storage state is lower.

[0026] In the case of a wide jack module, for example, a three-pronged jack module, the three jacks of the three-pronged jack module are arranged in a triangular shape, which makes the width of the three-pronged jack module large. The effect of reducing the thickness of the three-pronged jack module by rotating the three-pronged jack module is not obvious. The folding socket 200 provided in the embodiments of the present application can be used to power the electrical appliance by forming a three-pronged jack module with the first module 2 and the second module 3, and when the electrical appliance does not need to be powered, the first module 2 and the second module 3 are each rotated and stored, thereby sufficiently reducing the thickness of the folding socket 200.

[0027] Further, in the storage state, the first jack 21 and the second jack 31 face opposite directions, i.e., the depth direction of the first jack 21 is parallel to the depth direction of the second jack 31, avoiding the overall thickness of the folding socket 200 from becoming large due to the inclination of one of the first module 2 and the second module 3 relative to the other.

[0028] The folding socket 200 provided in the embodiments of the present application is rotatable relative to the shell 1 by setting the first module 2 and the second module 3, so that the folding socket 200 has an unfolded state and a storage state. In the unfolded state, the first jack 21 and the second jack 31 can be used to power the electrical appliance. At this time, the first module 2 and the second module 3 protrude from the shell 1, thereby facilitating plug-in connection. When the electrical appliance does not need to be powered, the first module 2 and the second module 3 are rotated and stored. By rotating the first module 2 and the second module 3, the thickness of the folding socket 200 is thinner in the storage state, effectively solving the problem of large thickness of the socket.

[0029] Please refer to FIGS. 1 to 4. In some embodiments, the first module 2 is provided with a first limiting part 22, and the second module 3 is provided with a second limiting part 32. The folding socket 200 further includes a limiting part 4, which includes a connecting part 41, a third limiting part 42 and a fourth limiting part 43 connected to both ends of the connecting part 41, respectively. In the unfolded state of the folding socket 200, the first limiting part 22 and the third limiting part 42 are in limiting cooperation, and the second limiting part 32 and the fourth limiting part 43 are in limiting cooperation.

[0030] Specifically, by limiting cooperation of the first limiting part 22 and the third limiting part 42, and limiting cooperation of the second limiting part 32 and the fourth limiting part 43, when the folding socket 200 is in the unfolded state, the first module 2 and the second module 3 can be relatively locked, the first module 2 is always in the first position, and the second module 3 is always in the third position, so that the stability of the folding socket 200 in the unfolded state is good.

[0031] Exemplarily, the first limiting part 22 comprises a first limiting hole, the second limiting part 32 comprises a second limiting hole, the third limiting part 42 comprises a first limiting column, and the fourth limiting part 43 comprises a second limiting column. When the folding socket 200 is in the unfolded state, the first limiting column is at least partially inserted into the first limiting hole, thereby preventing the first module 2 from rotating. Similarly, the second limiting column is at least partially inserted into the second limiting hole, thereby preventing the second module 3 from rotating. The first limiting column and the second limiting column are connected through the connecting part 41. The structure of the connecting part 41 is not specifically limited, and any structure that can achieve the connection of the first limiting column and the second limiting column can be used. Exemplarily, the connecting part 41 is a rod body or a plate body.

[0032] The size of the end of the first limiting column close to the first limiting hole is smaller than the size of the end of the first limiting column away from the first limiting hole, so that the end of the first limiting column close to the first limiting hole can be more easily inserted into the first limiting hole, thereby reducing the requirement for positioning accuracy. Optionally, the end of the first limiting column close to the first limiting hole is a bevel, a pyramid surface, or a conical surface. Similarly, the size of the end of the second limiting column close to the second limiting hole is smaller than the size of the end of the second limiting column away from the second limiting hole, so that the end of the second limiting column close to the second limiting hole can be more easily inserted into the second limiting hole. Optionally, the end of the second limiting column close to the second limiting hole is a bevel, a pyramid surface, or a conical surface.

[0033] Please refer to FIGS. 2-3. In some embodiments, the folding socket 200 further comprises an elastic member 5 and a sliding switch 6. The elastic member 5 is connected with the connecting part 41 and the shell 1, and exerts a force on the connecting part 41 to enable the first limiting part 22 and the third limiting part 42 to limit each other, and enable the second limiting part 32 and the fourth limiting part 43 to limit each other. The sliding switch 6 is slidingly arranged in the shell 1, and is in transmission connection with the connecting part 41. When the sliding switch 6 is slid, the sliding switch 6 can overcome the elastic force of the elastic member 5 to drive the first limiting part 22 and the third limiting part 42 to be disengaged from each other, and drive the second limiting part 32 and the fourth limiting part 43 to be disengaged from each other.

[0034] Specifically, the shell 1 is provided with a guide groove, the limiting piece 4 is arranged in the guide groove and can slide along the extension direction of the guide groove, the elastic piece 5 can be a spring, the opposite ends of the spring in the extension direction are connected with the connecting part 41 and the shell 1 respectively, when the folding socket 200 is not in the unfolded state, the spring is in the compressed state, the third limiting part 42 (the first limiting column) abuts against the first module 2, and the fourth limiting part 43 (the second limiting column) abuts against the second module 3; when the folding socket 200 is in the unfolded state, the third limiting part 42 (the first limiting column) is aligned with the first limiting part 22 (the first limiting hole), the fourth limiting part 43 (the second limiting column) is aligned with the second limiting part 32 (the second limiting hole), and the restoring force of the spring drives the limiting piece 4 to move, so that the first limiting column is inserted into the first limiting hole, the second limiting column is inserted into the second limiting hole, and the limiting cooperation is completed.

[0035] When power supply to the electrical appliance is not needed, the sliding switch 6 can be slid to drive the limiting piece 4 to move and make the first limiting column disengage from the first limiting hole and the second limiting column disengage from the second limiting hole, so as to release the locking of the first module 2 and the second module 3, and enable the first module 2 and the second module 3 to rotate and be stored.

[0036] In some embodiments, when the sliding direction of the sliding switch 6 is parallel to the extension direction of the guide groove, optionally, the connecting part 41 of the sliding switch 6 and the limiting piece 4 is fixedly connected, and the sliding switch 6 can directly drive the limiting piece 4 to slide along the extension direction of the guide groove when the sliding switch 6 slides.

[0037] Please refer to FIGS. 2-3 and 6-7, in other embodiments, there is an included angle between the sliding direction of the sliding switch 6 and the extension direction of the guide groove, for example, the sliding direction of the sliding switch 6 and the extension direction of the guide groove are perpendicular to each other. Optionally, the sliding switch 6 is provided with a strip-shaped groove 61, the extension direction of the strip-shaped groove 61 has a component in the sliding direction of the sliding switch 6 and the moving direction of the limiting piece 4, for example, there is an included angle between the extension direction of the strip-shaped groove 61 and the sliding direction of the sliding switch 6 and the included angle is not 90 degrees, and there is an included angle between the extension direction of the strip-shaped groove 61 and the moving direction of the limiting piece 4 and the included angle is not 90 degrees. The connecting part 41 is provided with a protrusion 411, the protrusion 411 is at least partially in the strip-shaped groove 61, when the sliding switch 6 slides, the protrusion 411 slides in the strip-shaped groove 61, so as to drive the limiting piece 4 to slide along the extension direction of the guide groove.

[0038] Referring to FIGS. 2-4 and 6-7, in some embodiments, the folding socket 200 further comprises a support guide 7 connected with the housing 1, the support guide 7 is arranged below the sliding switch 6, the support guide 7 comprises a support plate 71 and a guide plate 72 which are perpendicular to each other and connected, the side of the sliding switch 6 away from the connecting portion 41 is provided with a limiting groove 62, one end of the guide plate 72 extends into the limiting groove 62, thereby limiting and guiding the sliding switch 6 when the sliding switch 6 slides; one end of the support plate 71 is in sliding contact with the sliding switch 6, thereby supporting the sliding switch 6 to make the sliding switch 6 more stable.

[0039] Referring to FIGS. 2-3, in some embodiments, the first module 2 is provided with a first transmission portion 23, the second module 3 is provided with a second transmission portion 33, the first transmission portion 23 is in transmission connection with the second transmission portion 33, the first module 2 and the second module 3 rotate synchronously and in opposite directions.

[0040] Specifically, the first transmission portion 23 can be a gear or a toothed structure arranged in a circular arc shape, the second transmission portion 33 can also be a gear or a toothed structure arranged in a circular arc shape, the first transmission portion 23 is engaged with the second transmission portion 33, thereby making one of the first module 2 and the second module 3 rotate, the other one rotates synchronously in the opposite direction, for example, when the first module 2 rotates from the first position to the second position, the second module 3 can rotate from the third position to the fourth position through the transmission between the first transmission portion 23 and the second transmission portion 33, so that the first module 2 and the second module 3 are folded and stored synchronously.

[0041] Referring to FIGS. 2-5, in some embodiments, the shell 1 includes a first cavity 11 and a second cavity 12 arranged at intervals, the first cavity 11 and the second cavity 12 are arranged on both sides of the first module 2 and the second module 3 respectively, the first jack 21 includes a live jack and a zero jack, the second jack 31 includes a ground jack, the folding socket 200 further includes a first conductive spring 24, a second conductive spring 25, a third conductive spring 34, a first conductive terminal 26, a second conductive terminal 27 and a third conductive terminal 35, the first conductive spring 24 is arranged in the first cavity 11; the first conductive terminal 26 is connected with the first module 2 and rotates synchronously, the first conductive terminal 26 extends into the first cavity 11 and contacts with the first conductive spring 24, the first conductive terminal 26 is arranged corresponding to the live jack; the second conductive spring 25 is arranged in the second cavity 12; the second conductive terminal 27 is connected with the first module 2 away from the first conductive terminal 26 and rotates synchronously, the second conductive terminal 27 extends into the second cavity 12 and contacts with the second conductive spring 25, the second conductive terminal 27 is arranged corresponding to the zero jack; the third conductive spring 34 is arranged in the first cavity 11 or the second cavity 12; the third conductive terminal 35 is connected with the second module 3 and rotates synchronously, the third conductive terminal 35 extends into the first cavity 11 or the second cavity 12 and contacts with the third conductive spring 34, the third conductive terminal 35 is arranged corresponding to the ground jack.

[0042] Specifically, the folding socket 200 further includes a power cord 8, the power cord 8 includes a live wire, a zero wire and a ground wire, the live wire is electrically connected with the first conductive spring 24, the zero wire is electrically connected with the second conductive spring 25, and the ground wire is electrically connected with the third conductive spring 34, the first cavity 11 and the second cavity 12 are communicated, and the power cord 8 is arranged between the first cavity 11 and the second cavity 12.

[0043] The first module 2 contacts the first conductive spring 24 through the first conductive terminal 26 and the second conductive terminal 27 contacts the second conductive spring 25, so as to realize the conduction between the first jack 21 and the power cord 8, when the first module 2 rotates, the first conductive terminal 26 and the first conductive spring 24 slide contact, and the second conductive terminal 27 and the second conductive spring 25 slide contact, so that the first jack 21 and the power cord 8 always maintain the conduction state when the first module 2 rotates; similarly, the second module 3 contacts the third conductive spring 34 through the third conductive terminal 35, the third conductive terminal 35 and the third conductive spring 34 slide contact, so that the second jack 31 and the power cord 8 always maintain the conduction state.

[0044] Optionally, the first conductive spring 24 has a certain toughness, when the first conductive terminal 26 contacts the first conductive spring 24, the first conductive terminal 26 will extrude the first conductive spring 24 to make the first conductive spring 24 slightly deform, and the restoring force of the first conductive spring 24 will make the first conductive spring 24 always adhere to the first conductive terminal 26, ensuring that the live wire jack is always in conduction with the power cord 8. The first conductive terminal 26 is fixed on the first module 2 by in-mold encapsulation, and the first conductive terminal 26 and the first conductive spring 24 can be made of copper or other materials with good conductivity. The connection and cooperation between the second conductive terminal 27 and the second conductive spring 25 and the connection and cooperation between the third conductive terminal 35 and the third conductive spring 34 can refer to the connection and cooperation between the first conductive terminal 26 and the first conductive spring 24.

[0045] As shown in FIGS. 2-5, in some embodiments, the first conductive terminal 26 has a first abutting surface 261 and a second abutting surface 262, and the second conductive terminal 27 has a third abutting surface 271 and a fourth abutting surface 272; when the first module 2 is in the first position, the first abutting surface 261 abuts the first conductive spring 24, and the third abutting surface 271 abuts the second conductive spring 25; when the first module 2 is in the second position, the second abutting surface 262 abuts the first conductive spring 24, and the fourth abutting surface 272 abuts the second conductive spring 25; the third conductive terminal 35 has a fifth abutting surface 351 and a sixth abutting surface 352, when the second module 3 is in the third position, the fifth abutting surface 351 abuts the third conductive spring 34, and when the second module 3 is in the fourth position, the sixth abutting surface 352 abuts the third conductive spring 34.

[0046] Specifically, when the first module 2 is located at the first position, the first conductive terminal 26 abuts against the first conductive spring piece 24 through the first abutting surface 261; when the first module 2 is located at the second position, the first conductive terminal 26 abuts against the first conductive spring piece 24 through the second abutting surface 262, so that the first conductive terminal 26 and the first conductive spring piece 24 are in surface contact, and the contact area between the first conductive terminal 26 and the first conductive spring piece 24 is large, thereby avoiding poor contact, increased resistance, heating and other adverse effects caused by a small contact area, and ensuring good conductive effect. The shapes of the first abutting surface 261 and the second abutting surface 262 are not limited, as long as the contact area between the first conductive terminal 26 and the first conductive spring piece 24 is as large as possible. For example, the first abutting surface 261 is a flat surface or an arc surface. Similarly, the second conductive terminal 27 and the second conductive spring piece 25, and the third conductive terminal 35 and the third conductive spring piece 34 are in surface contact in the unfolded state and the stored state of the folding socket 200, and the contact area is large, so that the second conductive terminal 27 and the second conductive spring piece 25, and the third conductive terminal 35 and the third conductive spring piece 34 have good conductive effect.

[0047] In some embodiments, the first insulating layer is arranged on the second abutting surface 262, the second insulating layer is arranged on the fourth abutting surface 272, and the third insulating layer is arranged on the sixth abutting surface 352. The insulating layer may, for example, be insulating paint or insulating rubber.

[0048] When the first module 2 is located at the second position, the first insulating layer abuts against the first conductive spring piece 24, and the second insulating layer abuts against the second conductive spring piece 25, so that the first conductive terminal 26 and the first conductive spring piece 24 are insulated, and the second conductive terminal 27 and the second conductive spring piece 25 are insulated. When the second module 3 is located at the fourth position, the third conductive terminal 35 and the third conductive spring piece 34 are insulated, that is, the first module 2 and the second module 3 are not electrified at this time, so that the folding socket 200 is safer in the stored state.

[0049] As shown in FIGS. 2-5, in some embodiments, the junction of the first abutting surface 261 and the second abutting surface 262 has a first ridge line 263, the junction of the third abutting surface 271 and the fourth abutting surface 272 has a second ridge line 273, and when the first module 2 is switched between the first position and the second position, the first ridge line 263 presses against the first conductive spring piece 24, and the second ridge line 273 presses against the second conductive spring piece 25; the junction of the fifth abutting surface 351 and the sixth abutting surface 352 has a third ridge line 353, and when the second module 3 is switched between the third position and the fourth position, the third ridge line 353 presses against the third conductive spring piece 34.

[0050] Specifically, since the junction of the first abutting surface 261 and the second abutting surface 262 has the first ridge line 263, the transition between the first abutting surface 261 and the second abutting surface 262 is not smooth but angular, and due to the presence of the first ridge line 263, the first module 2 is difficult to rotate smoothly from the first position to the second position, so that the state of the first module 2 is more stable in the first position or the second position. Specifically, when the first module 2 switches between the first position and the second position, the first conductive terminal 26 rotates, the first ridge line 263 presses against the first conductive spring piece 24, and the first conductive spring piece 24 is slightly deformed. At this time, the first conductive terminal 26 only contacts the first conductive spring piece 24 through the first ridge line 263, and when the first module 2 rotates to the first position or the second position, the first conductive terminal 26 and the first conductive spring piece 24 are in surface contact. Due to the presence of the first ridge line 263, the first conductive terminal 26 cannot rotate easily, thereby making the first module 2 more likely to remain in the first position or the second position, ensuring that the first module 2 can remain stable in the unfolded state or the stored state.

[0051] In addition, the distance between the first ridge line 263 and the rotation axis of the first conductive terminal 26 is greater than the distance between the first abutting surface 261 or the second abutting surface 262 and the rotation axis of the first conductive terminal 26, so that when the first module 2 switches between the first position and the second position, the pressure between the first ridge line 263 and the first conductive spring piece 24 is greater, ensuring that the first ridge line 263 and the first conductive spring piece 24 are in good contact.

[0052] Similarly, the junction of the third abutting surface 271 and the fourth abutting surface 272 has a second ridge line 273, and when the first module 2 switches between the first position and the second position, the second conductive terminal 27 rotates, the second ridge line 273 presses against the second conductive spring piece 25, and the second conductive spring piece 25 is slightly deformed. At this time, the second conductive terminal 27 only contacts the second conductive spring piece 25 through the second ridge line 273, and when the first module 2 rotates to the first position or the second position, the second conductive terminal 27 and the second conductive spring piece 25 are in surface contact. Due to the presence of the second ridge line 273, the first module 2 can more easily remain in the first position or the second position, ensuring that the first module 2 can remain stable in the unfolded state or the stored state.

[0053] The junction of the fifth abutting surface 351 and the sixth abutting surface 352 has a third ridge line 353. When the second module 3 is switched between the third position and the fourth position, the third conductive terminal 35 rotates, the third ridge line 353 abuts against the third conductive spring piece 34, and the third conductive spring piece 34 is slightly deformed. At this time, the third conductive terminal 35 only contacts the third conductive spring piece 34 through the third ridge line 353. When the second module 3 rotates to the third position or the fourth position, the third conductive terminal 35 and the third conductive spring piece 34 are in surface contact. Due to the presence of the third ridge line 353, the second module 3 can be more easily kept in the third position or the fourth position, ensuring that the second module 3 can be kept stable in the unfolded state or the stored state.

[0054] In some embodiments, the rotation angle of the first module 2 when rotating from the first position to the second position is 90 degrees, and the rotation angle of the second module 3 when rotating from the third position to the fourth position is 90 degrees.

[0055] Specifically, when the shell 1 is placed horizontally, in the unfolded state, the first module 2 and the second module 3 are both vertically erected, at this time, the orifices of the first jack 21 and the second jack 31 are upward, the depth direction of the first jack 21 and the second jack 31 is the vertical direction, which is convenient for plugging with the plug of an electrical appliance. At this time, the depth direction of the first jack 21 and the second jack 31 is the thickness direction. When the folding socket 200 is switched from the unfolded state to the stored state, the first module 2 and the second module 3 are both rotated from the vertical state to the horizontal state, the depth direction of the first jack 21 and the second jack 31 is changed from the thickness direction to the width direction, and the original width direction of the first jack 21 and the second jack 31 is changed to the thickness direction. After the folding socket 200 is switched from the unfolded state to the stored state, the thickness of the first module 2 and the second module 3 is reduced, and thus the overall thickness of the folding socket 200 is reduced, which is convenient for carrying.

[0056] Please refer to FIGS. 1-3. In some embodiments, the shell 1 has a containing groove 13. When the folding socket 200 is in the stored state, the first module 2 and the second module 3 are both stored in the containing groove 13.

[0057] Specifically, the containing groove 13 is located on the outside of the shell 1, and the first chamber 11 and the second chamber 12 are symmetrically arranged on opposite sides of the containing groove 13 to improve the aesthetics of the folding socket 200. The first module 2 and the second module 3 are both rotationally connected with the groove wall of the containing groove 13. In the stored state, the first module 2 and the second module 3 are stored in the containing groove 13, thereby preventing the first module 2 and the second module 3 from being damaged, and also minimizing the overall thickness of the folding socket 200.
