Description

Technical Field

[0001] This application relates to the technical field of power supply devices, and particularly to a folding socket. Background Art

[0002] Sockets are essential tools in people's lives and can provide great convenience for people to utilize electrical energy.

[0003] When people are engaged in outdoor activities such as camping, they may carry a mobile power supply and a socket based on their electricity usage needs. However, since the depth of the jack needs to comply with relevant regulations, and the thickness of the socket is often greater than the depth of the jack, the thickness of the socket is often relatively thick and not convenient to carry. Summary of the Utility Model

[0004] This application provides a folding socket that can solve the problem of the relatively large thickness of the socket.

[0005] This application provides a folding socket, including: a housing, a first module, and a second module. The first module is hinged to the housing and has a first position and a second position in the rotation direction, and a first jack is provided on the first module; the second module is hinged to the housing and has a third position and a fourth position in the rotation direction, and a second jack is provided on the second module; wherein, the folding socket has an unfolded state and a stored 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 jack and the second jack face the same direction, and the first jack and the second jack together form a two-pin jack or a three-pin jack; when the folding socket is in the stored state, the first module is located at the second position, the second module is located at the fourth position, and the first jack and the second jack face opposite directions.

[0006] For the folding socket of this application, by setting that both the first module and the second module can rotate relative to the housing, the folding socket has an unfolded state and a stored state. In the unfolded state, the first jack and the second jack can be used to supply power to electrical appliances; when it is not necessary to supply power to electrical appliances, rotate and store the first module and the second module. By rotating the first module and the second module, the thickness of the folding socket is thinner in the stored state, effectively solving the problem of the relatively large thickness of the socket.

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0027] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0028] The following will be combined with Figures 1 to 5 to describe the foldable socket 200 of the present application.

[0029] Please refer to Figures 1 to 5 , the embodiments of the present application provide a foldable socket 200, which includes a housing 1, a first module 2 and a second module 3. The first module 2 is hinged to the housing 1 and has a first position and a second position in the rotation direction. The first module 2 is provided with a first jack 21; the second module 3 is hinged to the housing 1 and has a third position and a fourth position in the rotation direction. The second module 3 is provided with a second jack 31; wherein, the foldable socket 200 has an unfolded state and a stored state. As Figures 1 to 4 shown, when the foldable 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 jack 21 and the second jack 31 face the same direction. As Figure 5 shown, when the foldable socket 200 is in the stored state, the first module 2 is located at the second position, the second module 3 is located at the fourth position, and the first jack 21 and the second jack 31 face opposite directions.

[0030] Specifically, the housing 1 may have a flat structure, and its upper and lower end faces may be planes, so that the thickness of the housing 1 is thinner and the aesthetics is better.

[0031] Both the first jack 21 and the second jack 31 are used for plugging in the plug of an electrical appliance. In the unfolded state, the first jack 21 and the second jack 31 face the same direction, and the plug of the electrical appliance can be plugged into the first jack 21 and the second jack 31, so that the electrical appliance can obtain power. The first jack 21 can be part of a conventional jack (such as a three-pin jack or a two-pin jack, etc.), and the second jack 31 is another part of the conventional jack. In the unfolded state, the plug of the electrical appliance is plugged into the first jack 21 and the second jack 31. When power supply to the electrical appliance is not required, the first module 2 is flipped to the second position, and the second module 3 is flipped to the fourth position, so as to store the first module 2 and the second module 3. Since the depth of the jack needs to meet industry standards, this makes the thickness of the socket relatively large. By rotating the first module 2 and the second module 3, the depth direction of the first jack 21 and the second jack 31 can be changed, which helps to reduce the thickness of the first module 2 and the second module 3 in the storage state.

[0032] Exemplarily, the first module 2 is part of a three-pin jack module, the first jack 21 is part of the three-pin jack, the second module 3 is another part of the three-pin jack module, and the second jack 31 is another part of the three-pin jack. In the unfolded state, the first jack 21 and the second jack 31 face the same direction. The first module 2 and the second module 3 together form a three-pin jack module, and the first jack 21 and the second jack 31 together form a three-pin jack. The three-pin plug of the electrical appliance can be plugged into the first jack 21 and the second jack 31 at the same time to obtain power. When power supply to the electrical appliance is not required, 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.

[0033] Alternatively, the first module 2 is part of a two-pin jack module, the first jack 21 is part of the two-pin jack, the second module 3 is another part of the two-pin jack module, and the second jack 31 is another part of the two-pin jack. In the unfolded state, the first jack 21 and the second jack 31 face the same direction. The first module 2 and the second module 3 together form a two-pin jack module, and the first jack 21 and the second jack 31 together form a two-pin jack. The two-pin plug of the electrical appliance can be plugged into the first jack 21 and the second jack 31 at the same time to obtain power. When power supply to the electrical appliance is not required, 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.

[0034] Among them, for a jack module with a relatively large width, taking a three-pin jack module as an example, the three jacks of the three-pin jack module are distributed in a triangular shape, which makes the width of the three-pin jack module relatively large. The effect of reducing the thickness of the three-pin jack module by rotating the three-pin jack module is not obvious. However, the folding socket 200 provided in the embodiment of the present application can form a three-pin jack module by the first module 2 and the second module 3 together to supply power to an electrical appliance. And when it is not necessary to supply power to the electrical appliance, the first module 2 and the second module 3 are respectively rotated and stored, so as to fully reduce the thickness of the folding socket 200.

[0035] Further, in the storage state, the first jack 21 and the second jack 31 face in opposite directions, that is, the depth directions of the first jack 21 and the second jack 31 are parallel, so as to avoid the overall thickness of the folding socket 200 increasing due to one of the first module 2 and the second module 3 tilting relative to the other.

[0036] For the folding socket 200 of the present application, by setting that both the first module 2 and the second module 3 can rotate relative to the housing 1, 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 supply power to an electrical appliance. At this time, the first module 2 and the second module 3 protrude from the housing 1, so as to facilitate plugging. When it is not necessary to supply power to the electrical appliance, 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 the relatively large thickness of the socket.

[0037] Please refer to Figures 1 to 4 , in some embodiments, a first limiting portion 22 is provided on the first module 2, and a second limiting portion 32 is provided on the second module 3; the folding socket 200 further includes a limiting member 4, and the limiting member 4 includes a connecting portion 41, a third limiting portion 42 and a fourth limiting portion 43 respectively connected to both ends of the connecting portion 41. When the folding socket 200 is in the unfolded state, the first limiting portion 22 and the third limiting portion 42 are in limiting cooperation, and the second limiting portion 32 and the fourth limiting portion 43 are in limiting cooperation.

[0038] Specifically, through the limiting cooperation between the first limiting portion 22 and the third limiting portion 42, and the limiting cooperation between the second limiting portion 32 and the fourth limiting portion 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 always remains in the first position, and the second module 3 always remains in the third position, so that the folding socket 200 has better stability in the unfolded state.

[0039] Exemplarily, the first limiting portion 22 includes a first limiting hole, the second limiting portion 32 includes a second limiting hole, the third limiting portion 42 includes a first limiting post, and the fourth limiting portion 43 includes a second limiting post. When the folding socket 200 is in the unfolded state, the first limiting post is at least partially inserted into the first limiting hole to prevent the first module 2 from rotating; similarly, the second limiting post is at least partially inserted into the second limiting hole to prevent the second module 3 from rotating. The first limiting post and the second limiting post are connected by a connecting portion 41. The structure of the connecting portion 41 is not specifically limited, and any structure capable of connecting the first limiting post and the second limiting post is acceptable. Exemplarily, the connecting portion 41 is a rod or a plate.

[0040] The size of one end of the first limiting post close to the first limiting hole is smaller than the size of the end of the first limiting post far from the first limiting hole, so that the end of the first limiting post close to the first limiting hole can be more easily inserted into the first limiting hole, reducing the requirement for alignment accuracy. Optionally, the end of the first limiting post close to the first limiting hole is an inclined surface, a pyramid-shaped surface or a conical surface; similarly, the size of one end of the second limiting post close to the second limiting hole is smaller than the size of the end of the second limiting post far from the second limiting hole, so that the end of the second limiting post close to the second limiting hole can be more easily inserted into the second limiting hole. Optionally, the end of the second limiting post close to the second limiting hole is an inclined surface, a pyramid-shaped surface or a conical surface.

[0041] Please refer to Figures 2 to 3 , in some embodiments, the folding socket 200 further includes: an elastic member 5 and a sliding switch 6. The elastic member 5 is connected to the connecting portion 41 and the housing 1. The elastic member 5 applies a force to the connecting portion 41 to make the first limiting portion 22 and the third limiting portion 42 in limiting cooperation, and to make the second limiting portion 32 and the fourth limiting portion 43 in limiting cooperation. The sliding switch 6 is slidably disposed on the housing 1 and is in transmission connection with the connecting portion 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 portion 22 and the third limiting portion 42 to release the limit, and to drive the second limiting portion 32 and the fourth limiting portion 43 to release the limit.

[0042] Specifically, a guiding groove is provided on the housing 1. The limiting member 4 is disposed in the guiding groove and can slide along the extending direction of the guiding groove. The elastic member 5 can be a spring. The relative two ends of the spring in the telescopic direction are respectively connected to the connecting portion 41 and the housing 1. When the folding socket 200 is not in the unfolded state, the spring is in a compressed state. The third limiting portion 42 (the first limiting post) abuts against the first module 2, and the fourth limiting portion 43 (the second limiting post) abuts against the second module 3. When the folding socket 200 is in the unfolded state, the third limiting portion 42 (the first limiting post) is aligned with the first limiting portion 22 (the first limiting hole), and the fourth limiting portion 43 (the second limiting post) is aligned with the second limiting portion 32 (the second limiting hole). The restoring force of the spring drives the limiting member 4 to move, so that the first limiting post is inserted into the first limiting hole, and the second limiting post is inserted into the second limiting hole, completing the limiting cooperation.

[0043] When there is no need to supply power to the electrical appliance, the sliding switch 6 can be slid to drive the limiting member 4 to move and make the first limiting post disengage from the first limiting hole and the second limiting post disengage from the second limiting hole, thereby releasing the locking of the first module 2 and the second module 3, enabling the first module 2 and the second module 3 to rotate and be stored.

[0044] In some embodiments, when the sliding direction of the sliding switch 6 is parallel to the extending direction of the guiding groove, optionally, the sliding switch 6 is fixedly connected to the connecting portion 41 of the limiting member 4. When the sliding switch 6 slides, it can directly drive the limiting member 4 to slide along the extending direction of the guiding groove.

[0045] Please refer to Figures 2 to 3 and Figures 6 to 7 As shown, in some other embodiments, there is an included angle between the sliding direction of the sliding switch 6 and the extending direction of the guiding groove. For example, when the sliding direction of the sliding switch 6 is perpendicular to the extending direction of the guiding groove. Optionally, a strip-shaped groove 61 is provided on the sliding switch 6. The extending direction of the strip-shaped groove 61 has components in both the sliding direction of the sliding switch 6 and the moving direction of the limiting member 4. For example, there is an included angle between the extending 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 extending direction of the strip-shaped groove 61 and the moving direction of the limiting member 4 and the included angle is not 90 degrees. A protrusion 411 is provided on the connecting portion 41, and at least a part of the protrusion 411 is located in the strip-shaped groove 61. When the sliding switch 6 slides, the protrusion 411 slides in the strip-shaped groove 61, thereby driving the limiting member 4 to slide along the extending direction of the guiding groove.

[0046] Please refer to Figures 2 to 4 and Figures 6 to 7As shown, in some embodiments, the folding socket 200 further includes a support guide 7 connected to the housing 1. The support guide 7 is disposed below the sliding switch 6. The support guide 7 includes a support plate 71 and a guide plate 72 that are perpendicular to each other and connected. A limiting groove 62 is provided on a side of the sliding switch 6 facing away from the connecting portion 41. One end of the guide plate 72 extends into the limiting groove 62 to limit and guide 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 to support the sliding switch 6, making the sliding switch 6 more stable.

[0047] Please refer to Figures 2 to 3 , in some embodiments, a first transmission portion 23 is provided on the first module 2, and a second transmission portion 33 is provided on the second module 3. 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.

[0048] Specifically, the first transmission portion 23 can be a gear or a toothed structure arranged in an arc shape, and the second transmission portion 33 can also be a gear or a toothed structure arranged in an arc shape. The first transmission portion 23 meshes with the second transmission portion 33, so that when one of the first module 2 and the second module 3 rotates, the other rotates synchronously in the opposite direction. For example, when the first module 2 rotates from the first position to the second position, through the transmission between the first transmission portion 23 and the second transmission portion 33, the second module 3 can be rotated from the third position to the fourth position, enabling the first module 2 and the second module 3 to be folded and stored synchronously.

[0049] Please refer to Figures 2 to 5, in some embodiments, the housing 1 includes a first chamber 11 and a second chamber 12 which are spaced apart. The first chamber 11 and the second chamber 12 are respectively disposed on both sides of the first module 2 and the second module 3. The first jack 21 includes a live wire jack and a neutral wire jack. The second jack 31 includes a ground wire jack. The folding socket 200 further includes: a first conductive elastic piece 24, a second conductive elastic piece 25, a third conductive elastic piece 34, a first conductive terminal 26, a second conductive terminal 27, and a third conductive terminal 35. The first conductive elastic piece 24 is disposed in the first chamber 11; the first conductive terminal 26 is connected to the first module 2 and rotates synchronously. The first conductive terminal 26 extends into the first chamber 11 and contacts the first conductive elastic piece 24. The first conductive terminal 26 is disposed corresponding to the live wire jack; the second conductive elastic piece 25 is disposed in the second chamber 12; the second conductive terminal 27 is connected to the side of the first module 2 away from the first conductive terminal 26 and rotates synchronously. The second conductive terminal 27 extends into the second chamber 12 and contacts the second conductive elastic piece 25. The second conductive terminal 27 is disposed corresponding to the neutral wire jack; the third conductive elastic piece 34 is disposed in the first chamber 11 or the second chamber 12; the third conductive terminal 35 is connected to the second module 3 and rotates synchronously. The third conductive terminal 35 extends into the first chamber 11 or the second chamber 12 and contacts the third conductive elastic piece 34. The third conductive terminal 35 is disposed corresponding to the ground wire jack.

[0050] Specifically, the folding socket 200 further includes a power cord 8. The power cord 8 includes a live wire, a neutral wire, and a ground wire. The live wire is electrically connected to the first conductive elastic piece 24, the neutral wire is electrically connected to the second conductive elastic piece 25, and the ground wire is electrically connected to the third conductive elastic piece 34. The first chamber 11 communicates with the second chamber 12, facilitating the power cord 8 to be threaded between the first chamber 11 and the second chamber 12.

[0051] The first module 2 is in conduction with the power cord 8 by the first conductive terminal 26 contacting the first conductive elastic piece 24 and the second conductive terminal 27 contacting the second conductive elastic piece 25. When the first module 2 rotates, the first conductive terminal 26 makes sliding contact with the first conductive elastic piece 24, and the second conductive terminal 27 makes sliding contact with the second conductive elastic piece 25, so that when the first module 2 rotates, the first jack 21 and the power cord 8 always remain in a conductive state; similarly, the second module 3 is in conduction with the power cord 8 by the third conductive terminal 35 contacting the third conductive elastic piece 34, and the third conductive terminal 35 makes sliding contact with the third conductive elastic piece 34, so that the second jack 31 and the power cord 8 always remain in a conductive state.

[0052] Optionally, the first conductive elastic piece 24 has a certain toughness. When the first conductive terminal 26 contacts the first conductive elastic piece 24, the first conductive terminal 26 will squeeze the first conductive elastic piece 24, causing the first conductive elastic piece 24 to deform slightly. The restoring force of the first conductive elastic piece 24 will make the first conductive elastic piece 24 always fit with the first conductive terminal 26, ensuring that the live wire jack is always electrically connected to the power cord 8. Among them, the first conductive terminal 26 is fixed on the first module 2 by in-mold encapsulation. The first conductive terminal 26 and the first conductive elastic piece 24 can be made of materials with good electrical conductivity such as copper. The connection and cooperation method between the second conductive terminal 27 and the second conductive elastic piece 25 and the connection and cooperation method between the third conductive terminal 35 and the third conductive elastic piece 34 can refer to the connection and cooperation method between the first conductive terminal 26 and the first conductive elastic piece 24 above.

[0053] As Figures 2 to 5 shown, 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 against the first conductive elastic piece 24, and the third abutting surface 271 abuts against the second conductive elastic piece 25; when the first module 2 is in the second position, the second abutting surface 262 abuts against the first conductive elastic piece 24, and the fourth abutting surface 272 abuts against the second conductive elastic piece 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 against the third conductive elastic piece 34. When the second module 3 is in the fourth position, the sixth abutting surface 352 abuts against the third conductive elastic piece 34.

[0054] Specifically, when the first module 2 is in the first position, the first conductive terminal 26 abuts against the first conductive elastic sheet 24 through the first abutting surface 261; when the first module 2 is in the second position, the first conductive terminal 26 abuts against the first conductive elastic sheet 24 through the second abutting surface 262. This enables the first conductive terminal 26 and the first conductive elastic sheet 24 to be in surface contact whether the folding socket 200 is in the unfolded state or the stored state. The contact area between the first conductive terminal 26 and the first conductive elastic sheet 24 is relatively large, avoiding adverse effects such as poor contact, increased resistance, and heat generation caused by a small contact area, and ensuring good electrical conductivity. 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 elastic sheet 24 can be made as large as possible. Exemplarily, the first abutting surface 261 is a flat surface or an arc surface. Similarly, whether the folding socket 200 is in the unfolded state or the stored state, the second conductive terminal 27 and the second conductive elastic sheet 25, and the third conductive terminal 35 and the third conductive elastic sheet 34 are in surface contact, with a relatively large contact area, resulting in good electrical conductivity between the second conductive terminal 27 and the second conductive elastic sheet 25, and between the third conductive terminal 35 and the third conductive elastic sheet 34.

[0055] In some embodiments, a first insulating layer is provided on the second abutting surface 262, a second insulating layer is provided on the fourth abutting surface 272, and a third insulating layer is provided on the sixth abutting surface 352. Exemplarily, the insulating layer can be insulating paint, insulating rubber, etc.

[0056] When the first module 2 is in the second position, the first insulating layer abuts against the first conductive elastic sheet 24, and the second insulating layer abuts against the second conductive elastic sheet 25, thereby insulating the first conductive terminal 26 and the first conductive elastic sheet 24 from each other, and insulating the second conductive terminal 27 and the second conductive elastic sheet 25 from each other. When the second module 3 is in the fourth position, the third conductive terminal 35 and the third conductive elastic sheet 34 are insulated from each other, that is, at this time, neither the first module 2 nor the second module 3 is charged, making the folding socket 200 relatively safe in the stored state.

[0057] As Figures 2 to 5 shown, in some embodiments, there is a first ridge line 263 at the junction of the first abutting surface 261 and the second abutting surface 262, and a second ridge line 273 at the junction of the third abutting surface 271 and the fourth abutting surface 272. When the first module 2 switches between the first position and the second position, the first ridge line 263 presses against the first conductive elastic sheet 24, and the second ridge line 273 presses against the second conductive elastic sheet 25; there is a third ridge line 353 at the junction of the fifth abutting surface 351 and the sixth abutting surface 352. When the second module 3 switches between the third position and the fourth position, the third ridge line 353 presses against the third conductive elastic sheet 34.

[0058] Specifically, since there is a first ridge line 263 at the junction of the first abutting surface 261 and the second abutting surface 262, the transition between the first abutting surface 261 and the second abutting surface 262 is not a smooth transition but a sharp-corner transition. Due to the existence of the first ridge line 263, it is difficult for the first module 2 to smoothly rotate from the first position to the second position, so that the first module 2 is in a relatively stable state when 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, and the first ridge line 263 presses against the first conductive elastic piece 24, causing the first conductive elastic piece 24 to deform slightly. At this time, the first conductive terminal 26 contacts the first conductive elastic piece 24 only through the first ridge line 263. When the first module 2 rotates to the first position or the second position, the contact between the first conductive terminal 26 and the first conductive elastic piece 24 is a surface contact. Due to the existence of the first ridge line 263, the first conductive terminal 26 cannot rotate easily, thus making it easier for the first module 2 to stay 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.

[0059] 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. 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 elastic piece 24 is relatively large, ensuring good contact between the first ridge line 263 and the first conductive elastic piece 24.

[0060] Similarly, there is a second ridge line 273 at the junction of the third abutting surface 271 and the fourth abutting surface 272. When the first module 2 switches between the first position and the second position, the second conductive terminal 27 rotates, and the second ridge line 273 presses against the second conductive elastic piece 25, causing the second conductive elastic piece 25 to deform slightly. At this time, the second conductive terminal 27 contacts the second conductive elastic piece 25 only through the second ridge line 273. When the first module 2 rotates to the first position or the second position, the contact between the second conductive terminal 27 and the second conductive elastic piece 25 is a surface contact. Due to the existence of the second ridge line 273, the first module 2 can more easily stay 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.

[0061] At the junction of the fifth abutting surface 351 and the sixth abutting surface 352, there is a third ridge line 353. When the second module 3 switches between the third position and the fourth position, the third conductive terminal 35 rotates, and the third ridge line 353 presses against the third conductive elastic piece 34, causing the third conductive elastic piece 34 to deform slightly. At this time, the third conductive terminal 35 contacts the third conductive elastic piece 34 only through the third ridge line 353. When the second module 3 rotates to the third position or the fourth position, it is a surface contact between the third conductive terminal 35 and the third conductive elastic piece 34. Due to the existence of the third ridge line 353, the second module 3 can be more easily maintained in the third position or the fourth position, ensuring that the second module 3 can remain stable in the unfolded state or the stored state.

[0062] In some embodiments, when the first module 2 rotates from the first position to the second position, the rotation angle is 90 degrees, and when the second module 3 rotates from the third position to the fourth position, the rotation angle is 90 degrees.

[0063] Specifically, when the housing 1 is placed horizontally, in the unfolded state, both the first module 2 and the second module 3 stand upright. At this time, the orifices of the first jack 21 and the second jack 31 face upward, and the depth directions of the first jack 21 and the second jack 31 are in the vertical direction, facilitating the insertion of the plug of the electrical appliance. At this time, the depth directions of the first jack 21 and the second jack 31 are the thickness directions; when the folding socket 200 switches from the unfolded state to the stored state, both the first module 2 and the second module 3 rotate from the vertical state to the horizontal state, and the depth directions of the first jack 21 and the second jack 31 change from the thickness direction to the width direction, while the original width directions of the first jack 21 and the second jack 31 change to the thickness direction, so that after the folding socket 200 switches from the unfolded state to the stored state, the thickness of the first module 2 and the second module 3 becomes smaller, and further the overall thickness of the folding socket 200 becomes smaller, facilitating carrying.

[0064] Please refer to Figures 1 to 3 In some embodiments, the housing 1 has a receiving groove 13. When the folding socket 200 is in the stored state, both the first module 2 and the second module 3 are received in the receiving groove 13.

[0065] Specifically, the receiving groove 13 is located on the outside of the housing 1, and the first chamber 11 and the second chamber 12 are symmetrically arranged on opposite sides of the receiving groove 13 to improve the aesthetics of the folding socket 200. Both the first module 2 and the second module 3 are rotatably connected to the groove wall of the receiving groove 13. In the stored state, the first module 2 and the second module 3 are received in the receiving groove 13, thus preventing the first module 2 and the second module 3 from being damaged and also being able to minimize the overall thickness of the folding socket 200 as much as possible.
