Description

Technical Field

[0001] This invention relates to the field of power supply devices, and more particularly to a multi-dimensional adjustable power supply device and its expandable power supply module. Background Technology

[0002] Power strips are common power supply devices widely used in production and daily life. However, their placement is often haphazard, making them highly susceptible to contamination from water, dust, and other contaminants, which can damage their functionality and pose a safety hazard when connected to a power source. When using a power strip, multiple devices are typically connected to it. Since these devices (such as monitors, computer towers, and desk lamps) come from different locations and have varying plug styles, cord lengths, and stiffness, plugs from the back of the strip (with the socket side as the front) must be swiped around to insert them. This makes it difficult to neatly arrange the power strip on a table, affecting its tidiness. Furthermore, the power strip is subject to pulling from various directions, making it inconvenient to connect other devices and causing overall inconvenience.

[0003] Based on this, a prior patent with publication number CN219106708U discloses a serpentine versatile power strip, comprising multiple socket units rotatably connected in sequence. Each socket unit has a connecting groove and a connecting portion at both ends. When two adjacent socket units are connected, the connecting portion is embedded in the connecting groove and rotates relative to it. The rotation axes of the connecting groove and the connecting portion are positioned relative to the width direction of the socket unit, and a through hole is formed along the rotation axis. The conductive component passes through this through hole, ensuring electrical connection between the two socket units even when they rotate. This serpentine versatile power strip utilizes multiple socket units rotatably connected in sequence, allowing for adjustment of the socket assembly's orientation. It can be twisted into various angles along its length to fit the installation environment.

[0004] Alternatively, a prior patent with publication number "CN219106622U" discloses a multi-dimensional lifting and concealed power supply device, including a base cylinder embedded inside a table hole and a socket body longitudinally movable inside the base cylinder. The socket body includes multiple socket units rotatably connected in sequence, with adjacent socket units capable of rotating relative to each other and circumferentially positioned based on a pivot point. Furthermore, adjacent socket units are electrically connected, with conductive components passing through the rotatable connection between the two socket units, ensuring electrical connection even when the two sockets rotate. Each socket unit in this solution is rotatable and adjustable, thereby adjusting the orientation of the socket assembly for convenient plugging and unplugging and adapting to various power supply needs.

[0005] Both of the aforementioned prior art technologies propose that each socket unit can be rotated and adjusted to change the power supply orientation. However, the power strips or power supply devices involved in these prior art technologies cannot be expanded; specifically, this means that, on the one hand, to achieve rotational adjustment, and on the other hand, to consider electrical safety, the aforementioned power strips or power supply devices must be installed and set at the factory. Thus, users cannot increase or decrease the number of power supplies, nor can they select a suitable power supply model. Summary of the Invention

[0006] To address the aforementioned problems, the primary objective of this invention is to provide an expandable power supply module. Users can select an appropriate number of power supply modules to combine according to their needs, or choose power supply modules with suitable socket components (such as three-hole, two-hole, or different national standards).

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An expandable power supply module is characterized by comprising a socket unit and a terminal module that is directly or indirectly rotatably connected to the socket unit; the socket unit has a conductive component inside, and a socket assembly is disposed on the end face of the socket unit and connected to the conductive component inside; the terminal module is provided with a first wiring terminal, and the other end of the socket unit is directly or spaced out with a second wiring terminal, the first wiring terminal and the second wiring terminal being adaptable to be plugged in, and the conductive component inside the socket unit is connected to the second wiring terminal and passes through a hinged end to connect to the first wiring terminal.

[0009] The present invention adopts the above-described technical solution, which relates to an expandable power supply module. The expandable power supply module includes a socket unit and a terminal module rotatably connected at least one end. A first wiring terminal is provided on the terminal module, while a second wiring terminal is directly or intermittently provided at the other end of the socket unit. Based on this, multiple expandable power supply modules can be spliced ​​together, and the first and second wiring terminals of two adjacent expandable power supply modules are plugged into each other to achieve electrical connection.

[0010] In this solution, the socket unit and terminal module of the expandable power supply module are rotatably connected and the conductive parts are hidden inside. Under the premise of ensuring safety, this solution can realize the rotation and adjustment between multiple socket units as described in the background art solution; furthermore, it can realize expanded installation. Users can select an appropriate number of power supply modules to combine according to their needs, or select power supply modules with appropriate socket components (such as three-hole, two-hole or different national standards).

[0011] In one embodiment, a terminal module is also rotatably connected to the other end of the socket unit, and a second terminal is disposed on the terminal module on that side. The conductive component inside the socket unit passes through the hinged end and connects to the second terminal. In this embodiment, terminal modules are rotatably connected to both ends of the socket unit, and a first terminal and a second terminal are respectively installed thereon, enabling plug-in electrical connection. Furthermore, both terminal modules can rotate relative to the socket unit, providing greater flexibility.

[0012] In a specific design, the socket unit has a connecting groove or connecting part at its end, and the terminal module has a connecting part or connecting groove. When the terminal module is connected to the socket unit, the connecting part is embedded in the connecting groove and rotates relative to the connecting groove. The rotation axes of the connecting groove and the connecting part are set relative to the width direction of the socket unit, and a through hole is formed along the rotation axis. The conductive component passes through this through hole, ensuring electrical connection even when the terminal module rotates relative to the socket unit. The socket unit and the terminal module at its end rotate relative to each other by embedding the connecting part into the connecting groove, and are connected by the through hole of the connecting groove and the connecting part, allowing the conductive component to pass through the through hole along the axis. When the terminal module rotates relative to the socket unit, it will not interfere with the conductive component.

[0013] In another embodiment, the socket unit and the terminal module are rotatably connected via a rotating base. The rotation axis of the rotating base, socket unit, and terminal module is set relative to the width direction of the socket unit, and a through hole for wiring is formed along the rotation axis at the hinge. Conductive components pass through the rotating base and the through hole, ensuring that the socket unit and terminal module remain electrically connected when rotating relative to the rotating base. This solution provides an expandable power supply module, in which the rotating base is rotatably connected to the socket units and terminal modules on both sides. This allows for a larger relative rotation angle between the socket units and terminal modules, resulting in greater torsional flexibility for the entire power supply device. It not only adapts to a wider range of environments but also minimizes space occupation by rotating and folding when stored.

[0014] The expandable power supply module here is used for plug-in expansion. In the expanded state, the terminal module is plugged into the socket unit on another module. The above scheme can increase the relative rotation angle between two adjacent socket units. For example, if the rotation angle of a single socket unit relative to the rotating seat is 180°, then the relative folding angle between two adjacent socket units is 360°.

[0015] Preferably, the distance between the two pivot points on the rotating base is approximately equal to the thickness of the socket unit, so that the two socket units can be stacked together after rotating along the rotating base. Based on the above scheme, it can be ensured that the two socket units can be stacked together in the thickness direction when stored.

[0016] In a specific implementation, a connecting portion protrudes outward from the middle of the end of the socket unit; two rotating seats are respectively disposed on both sides of the connecting portion of the two socket units, and both rotating seats are rotatably connected to the two connecting portions. In this scheme, the rotating seats are two independent or interconnected units, respectively disposed on the left and right sides, and the connecting portion is rotatably disposed between the two rotating seats. Furthermore, the connecting portions of the two socket units are both constructed as arcs; when two adjacent socket units are connected to the rotating seats, the rotation paths of the two arc-shaped connecting portions do not interfere with each other.

[0017] Preferably, the socket unit and terminal module have a first through hole on their sidewalls, and the rotating base has an outwardly protruding shaft. This design is based on the shaft being embedded inside the first through hole, allowing the rotating base to rotate relative to the socket unit or terminal module. This enables the entire power supply device to adjust the installation angle and power supply direction.

[0018] Preferably, the socket unit, terminal module, and / or rotating base are provided with a locking component for circumferentially locking the rotating base to the socket unit and terminal module. This locking component can be any existing structure for locking the pivot, including but not limited to a mating structure of positioning grooves and positioning protrusions. The main purpose of this locking component is to enable the socket unit and rotating base to be positioned circumferentially to maintain their current angle.

[0019] In the specific implementation scheme, a concealed rotary locking structure is adopted. Multiple positioning grooves are arranged circumferentially on the inner wall of the first through hole, and a spring-loaded pin assembly is embedded in the rotating shaft. The output end of the spring-loaded pin assembly extends from the side wall of the rotating shaft and can be supported in the positioning groove on the inner wall of the first through hole, thereby circumferentially locking the socket unit, terminal module, and rotating seat. Based on the spring-loaded pin assembly embedded in the rotating shaft entering or exiting the positioning groove, the circumferential locking or unlocking of the socket unit, terminal module, and rotating seat is controlled; ultimately, the angle adjustment and positioning of the socket unit, terminal module, and rotating seat are achieved, and in the locked state, it is ensured that the socket unit, terminal module, and rotating seat do not loosen.

[0020] Preferably, the sidewall of the positioning groove is constructed as a guiding arc-shaped surface or slope. In this design, the shape of the positioning groove allows the output end of the elastic pin assembly to extend or retract as it presses against the sidewall during the relative rotation (either forward or reverse) of the socket unit, terminal module, and rotating seat. In other words, when adjusting the angle of the socket unit, terminal module, and rotating seat using this technical solution, only a twisting motion is needed; the output end of the elastic pin assembly will then exit the positioning groove during the twisting process and engage with it in its final position.

[0021] Preferably, a second through hole is formed at the center of the rotating shaft; when the rotating shaft is embedded inside the first through hole, the second through hole communicates with the first through hole to form a wiring channel for conductive components to pass through. It is required that the center of the rotating shaft is not closed, that is, at least the second through hole communicates with the first through hole, so that conductive components (such as wires) can pass through when wiring inside the power supply device.

[0022] Preferably, a positioning seat is formed inside the rotating shaft, and the elastic pin assembly is embedded inside the positioning seat. The rotating seat includes a second upper shell and a second lower shell. The positioning seat includes an upper seat body disposed on the second upper shell and a lower seat body disposed on the second lower shell. A groove is formed on the mating surface of the upper seat body and / or the lower seat body, and an opening is constructed on the side of the groove. The elastic pin assembly is embedded in the groove, and the output end of the elastic pin assembly extends out of the opening. When the lower seat body and the upper seat body are mated, they cover and close the groove. In this solution, the rotating seat is formed by the mating of the second upper shell and the second lower shell, and can be fastened with screws. The second upper shell and the second lower shell can be respectively provided with the upper seat body and the lower seat body, which are mated to form the positioning seat. Here, a groove is formed on the mating surface of the upper seat body and / or the lower seat body. During installation, the elastic pin assembly can be embedded in the groove, and then the second upper shell and the second lower shell are mated, and the upper seat body and the lower seat body are closed, that is, the elastic pin assembly is hidden and stored therein. In this way, the elastic pin assembly can be hidden and stored, ensuring that the elastic pin assembly is inside the groove and will not be misaligned during use.

[0023] In a specific implementation, the elastic pin assembly includes a pin movably disposed within a groove, and an elastic component with its output end supported on the pin; the elastic component may be a spring, with the spring supporting the inner end of the pin and the outer end of the pin extending out of the opening. It is necessary to prevent the pin from being pushed out of the opening under the action of the spring, therefore a corresponding limiting structure is required.

[0024] Preferably, both the socket unit and the terminal module include a first upper housing and a first lower housing; a radially extending edge is formed on the outer end of the rotating shaft; the sidewall of the first through hole is fitted between the edge and the sidewall of the rotating seat, and the output end of the elastic pin assembly extends from the sidewall of the rotating shaft between the edge and the sidewall of the rotating seat. In this design, the socket unit and terminal module are formed by mating the first upper housing and the first lower housing, and can be secured with screws. Because the socket unit and terminal module are composed of the above two parts, a radially extending edge is allowed to be formed on the outer end of the rotating shaft. During installation, the rotating shaft on the sidewall of the rotating seat is first inserted into the first through hole of the first lower housing, and then the first upper housing is closed. This ensures that the sidewall of the first through hole is fitted between the edge and the sidewall of the rotating seat, and the socket unit, terminal module, and rotating seat will not detach.

[0025] In another embodiment, the resilient pin assembly is constructed as a resilient element disposed on the outer wall of the rotating shaft. A partial arch of the resilient element extends into a positioning groove to circumferentially lock the socket unit, terminal module, and rotating seat. In this embodiment, the resilient pin assembly is simply a resilient element, which can be a spring sheet, spring wire, or a protrusion with material elasticity, such as a plastic protrusion. During circumferential rotation of the socket unit or terminal module relative to the rotating seat, the arched portion of the resilient element is pressed into or out of the positioning groove, achieving circumferential positioning and adjustment.

[0026] Preferably, a protective cover is provided on the first or second terminal. In this design, to ensure safety when using the expandable power supply module, a protective cover is provided on the first or second terminal. The protective cover can seal the terminal interface at the end and can only be removed when plugging in. The protective cover can be detachable and reusable, or it can be disposable, meaning it cannot be reattached after removal, thus encouraging users to avoid plugging and unplugging the expansion module after expansion is complete.

[0027] The second objective of this invention is to provide a multi-dimensional adjustable power supply device, characterized by comprising multiple power supply modules connected in sequence, wherein the power supply modules are expandable power supply modules as described above. This solution assembles and connects multiple expandable power supply modules into a power strip to achieve expandable arrangement; simultaneously, each expandable power supply module can be rotated to adjust its angle.

[0028] A third objective of this invention is to provide another multi-dimensional adjustable power supply device, characterized by: a socket body comprising a plurality of socket units rotatably connected in sequence, and a power receiving module rotatably connected to the last socket unit; adjacent socket units or a socket unit and the power receiving module can rotate relative to each other and be circumferentially positioned based on a pivot point; and the power receiving module is electrically connected to the plurality of socket units, with conductive components passing through the rotatable connection portion, so that the power receiving module remains electrically connected when rotating relative to the socket units or adjacent socket units; the power receiving module is provided with a second terminal; characterized by: further comprising an expandable power supply module as described above; the first terminal of the terminal module of the expandable power supply module can be plugged into the second terminal of the power receiving module. This solution is based on the prior patents with publication number CN219106708U and CN219106622U, and can be expanded using the aforementioned expandable power supply module.

[0029] In a further preferred embodiment, adjacent socket units are rotatably connected via a rotating base, as are socket units and power-connecting modules. The rotation axes of the rotating base and the socket units / power-connecting modules on both sides are positioned relative to the width direction of the socket unit, and a through-hole for wiring is formed along the rotation axis at the hinge. Conductive components pass through the rotating base and the through-hole, ensuring electrical connection even when multiple socket units and power-connecting modules rotate. Adjacent socket units of the socket body are rotatably connected via a rotating base, and the rotating base and the socket units on both sides can rotate relative to each other. This allows for a larger relative rotation angle between adjacent socket units, resulting in greater torsional flexibility for the entire power supply device. This not only broadens environmental adaptability but also minimizes space occupation during storage through rotation and folding.

[0030] Furthermore, the distance between the two pivot points on the rotating base is approximately equal to the thickness of the socket unit, so that the two socket units can be stacked together after rotating along the rotating base. Based on the above scheme, it can be ensured that the two socket units can be stacked together in the thickness direction when stored. Attached Figure Description

[0049] Example 1:

[0050] like Figures 1-10 As shown, this embodiment relates to an expandable power supply module, including a socket unit 1 and a terminal module 2 that is directly or indirectly rotatably connected to the socket unit 1; the socket unit 1 is provided with a conductive component inside, and a socket assembly 10 is provided on the end face of the socket unit 1 and connected to the conductive component inside it; the terminal module 2 is provided with a first wiring terminal 21, and the other end of the socket unit 1 is provided with a second wiring terminal 11 directly or at intervals, the first wiring terminal 21 and the second wiring terminal 11 can be adapted to be plugged in, and the conductive component in the socket unit 1 is connected to the second wiring terminal 11 and passes through the hinge end to connect to the first wiring terminal 21.

[0051] like Figure 1 As shown, the expandable power supply module 100 includes a socket unit 1 and a terminal module 2 rotatably connected at least one end. A first wiring terminal 21 is provided on the terminal module 2, while a second wiring terminal 11 is directly or intermittently provided at the other end of the socket unit 1. Based on this, multiple expandable power supply modules 100 can be spliced ​​together, with the first wiring terminal 21 and second wiring terminal 11 of adjacent expandable power supply modules 100 being plugged in to achieve electrical connection. In this solution, the socket unit 1 and terminal module 2 of the expandable power supply module 100 are rotatably connected, and the conductive components are hidden inside. This solution, while ensuring safety, allows for the rotational adjustment of multiple socket units 1 as described in the background art; furthermore, it enables expanded installation, allowing users to select an appropriate number of power supply modules for combination according to their needs, or to choose suitable socket components 10 such as three-hole, two-hole, or power supply modules of different national standards.

[0052] exist Figure 2In one embodiment shown, a terminal module 2 is also rotatably connected to the other end of the socket unit 1. A second terminal 11 is disposed on the terminal module 2 on this side, and a conductive component inside the socket unit 1 passes through the hinged end to connect to the second terminal 11. In this embodiment, both ends of the socket unit 1 are rotatably connected to the terminal module 2, and a first terminal 21 and a second terminal 11 are respectively installed thereon, enabling plug-in electrical connection. Furthermore, both terminal modules 2 can rotate relative to the socket unit 1, providing greater flexibility.

[0053] exist Figure 1 and 2 In the specific embodiment shown, a connecting groove 12 or a connecting portion 22 is constructed on the end of the socket unit 1, and a connecting portion 22 or a connecting groove 12 is constructed on the terminal module 2. When the terminal module 2 is connected to the socket unit 1, the connecting portion 22 is embedded in the connecting groove 12 and rotates relative to the connecting groove 12. The rotation axes of the connecting groove 12 and the connecting portion 22 are arranged relative to the width direction of the socket unit 1, and a through hole is formed along the rotation axis. The conductive component passes through the through hole, so that the terminal module 2 remains electrically connected when rotating relative to the socket unit 1. The socket unit 1 and the terminal module 2 at its end achieve mutual rotation by embedding the connecting portion 22 into the connecting groove 12, and are connected by the through hole of the connecting groove 12 and the connecting portion 22, which allows the conductive component to pass through the through hole along the axis. When the terminal module 2 rotates relative to the socket unit 1, it will not interfere with the conductive component.

[0054] exist Figure 3 In another embodiment shown, the socket unit 1 and the terminal module 2 are rotatably connected via a rotating base 3. The rotation axis of the rotating base 3 and the socket unit 1 and terminal module 2 is set relative to the width direction of the socket unit 1, and a through hole 20 for wiring is formed along the rotation axis at the hinge. Conductive components pass through the rotating base 3 and the through hole 20, so that the socket unit 1 and terminal module 2 remain electrically connected when rotating relative to the rotating base 3. The expandable power supply module 100 provided by this solution has the rotating base 3 rotatably connected to the socket unit 1 and terminal module 2 on both sides. In this way, the relative rotation angle between the socket unit 1 and the terminal module 2 is larger, and the torsional flexibility of the entire power supply device is higher. It not only adapts to a wider range of environments, but also minimizes the space occupied by rotating and folding when stored. The expandable power supply module 100 here is used for plug-in expansion. In the expanded state, the terminal module 2 is plugged into the socket unit 1 on another module. The above scheme can increase the relative rotation angle between two adjacent socket units 1. For example, if the rotation angle of a single socket unit 1 relative to the rotating seat 3 is 180°, then the relative folding angle between two adjacent socket units 1 is 360°.

[0055] In such Figure 5In the illustrated scheme, the distance between the two pivot points on the rotating base 3 is approximately equal to the thickness of the socket unit 1, so that the two socket units 1 can be stacked together after rotating along the rotating base 3. Based on the above scheme, it can be ensured that the two socket units 1 can be stacked together in the thickness direction when stored. In a specific implementation, a connecting part 22 is provided protruding outward from the middle of the end of the socket unit 1; there are two rotating bases 3, which are respectively provided on both sides of the connecting part 22 of the two socket units 1, and both rotating bases 3 are rotatably connected to the two connecting parts 22. In this scheme, the rotating bases 3 are two independent or connected to each other, respectively provided on the left and right sides, and the connecting part 22 is rotatably provided between the two rotating bases 3. Further, the connecting parts 22 of the two socket units 1 are both constructed as arcs; when two adjacent socket units 1 are connected to the rotating base 3, the rotation paths of the two arc-shaped connecting parts 22 do not interfere with each other.

[0056] like Figure 6 As shown, the socket unit 1 and terminal module 2 have a first through hole 13 on their side walls, and the rotating base 3 has an outwardly protruding rotating shaft 24. This design is based on the rotating shaft 24 being embedded inside the first through hole 13, so that the rotating base 3 can rotate relative to the socket unit 1 or terminal module 2. This allows the entire power supply device to have the effects of adjusting the installation angle and power supply direction.

[0057] The socket unit 1, terminal module 2, and / or rotating base 3 are provided with a locking component 4, which is used to circumferentially lock the rotating base 3 to the socket unit 1 and terminal module 2. The locking component 4 can be any existing structure for locking the rotating shaft 24, including but not limited to a mating structure of positioning grooves and positioning protrusions. The locking component 4 primarily enables the socket unit 1 and rotating base 3 to be positioned circumferentially to maintain their current angle.

[0058] In such Figure 7 and 8 The specific implementation shown employs a concealed rotary locking structure. Multiple positioning grooves 131 are arranged circumferentially on the inner wall of the first through hole 13. An elastic pin assembly, i.e., the locking assembly 4, is embedded within the rotating shaft 24. The output end of the elastic pin assembly extends from the side wall of the rotating shaft 24 and can be supported within the positioning grooves 131 on the inner wall of the first through hole 13, thereby circumferentially locking the socket unit 1, terminal module 2, and rotating seat 3. Based on the elastic pin assembly embedded in the rotating shaft 24 entering or exiting the positioning grooves 131, the circumferential locking or unlocking of the socket unit 1, terminal module 2, and rotating seat 3 is controlled. Ultimately, the angle adjustment and positioning of the socket unit 1, terminal module 2, and rotating seat 3 are achieved, and in the locked state, it is ensured that the socket unit 1, terminal module 2, and rotating seat 3 do not loosen.

[0059] Furthermore, the sidewall 132 of the positioning groove 131 is constructed as a guiding arc-shaped surface or inclined surface. In this design, the shape of the positioning groove 131 allows the output end of the elastic pin assembly to extend or retract when it presses against the sidewall 132 during the relative rotation of the socket unit 1, terminal module 2, and rotating seat 3 (either forward or reverse). In other words, when adjusting the angle of the socket unit 1, terminal module 2, and rotating seat 3 using this technical solution, only a twisting motion is needed. The output end of the elastic pin assembly can then exit the positioning groove 131 during the twisting process and engage in the positioning groove 131 at its final position.

[0060] like Figure 9 As shown, a second through hole 23 is formed at the center of the rotating shaft 24; when the rotating shaft 24 is embedded inside the first through hole 13, the second through hole 23 communicates with the first through hole 13 to form a wiring channel for conductive components to pass through. It is required that the center of the rotating shaft 24 is not closed, that is, at least the second through hole 23 communicates with the first through hole 13, so that conductive components (such as wires) can pass through when wiring inside the power supply device.

[0061] like Figure 10As shown, a positioning seat 5 is formed inside the rotating shaft 24, and an elastic pin assembly is embedded inside the positioning seat 5. The rotating seat 3 includes a second upper shell 3a and a second lower shell 3b. The positioning seat 5 includes an upper seat body 51 disposed on the second upper shell 3a and a lower seat body 52 disposed on the second lower shell 3b. A groove 53 is formed on the mating surface of the upper seat body 51 and / or the lower seat body 52, and an opening 54 is constructed on the side of the groove 53. The elastic pin assembly is embedded in the groove 53, and the output end of the elastic pin assembly extends out of the opening 54. When the lower seat body 52 and the upper seat body 51 are mated, they cover and close the groove 53. In this scheme, the rotating seat 3 is formed by the mating of the second upper shell 3a and the second lower shell 3b, and can be fastened with screws. The upper seat body 51 and the lower seat body 52 can be respectively disposed on the second upper shell 3a and the second lower shell 3b, and are mated to form the positioning seat 5. Here, a groove 53 is formed on the mating surface of the upper seat 51 and / or the lower seat 52. During installation, the elastic pin assembly can be inserted into the groove 53, and then the second upper housing 3a and the second lower housing 3b are mated together, with the upper seat 51 and the lower seat 52 covering each other, thus hiding the elastic pin assembly within it. This hides and stores the elastic pin assembly, ensuring that it is inside the groove 53 and will not be misaligned during use. In a specific implementation, the elastic pin assembly includes a pin 41 movably disposed within the groove 53, and an elastic component 42 with its output end supported on the pin 41; the elastic component 42 can be a spring, with the spring supporting the inner end of the pin 41 and the outer end of the pin 41 extending out of the opening 54. It is necessary to prevent the pin 41 from being pushed out of the opening 54 under the action of the spring, therefore a corresponding limiting structure is required.

[0062] like Figure 6 As shown, both the socket unit 1 and the terminal module 2 include a first upper housing 1a and a first lower housing 1b; a radially extending edge 25 is constructed on the outer end of the rotating shaft 24; the sidewall of the first through hole 13 is fitted between the edge 25 and the sidewall of the rotating seat 3, and the output end of the elastic pin assembly extends from the sidewall of the rotating shaft 24 between the edge 25 and the sidewall of the rotating seat 3. In this scheme, the socket unit 1 and the terminal module 2 are formed by connecting the first upper housing 1a and the first lower housing 1b, and can be fastened with screws. Since the socket unit 1 and the terminal module 2 are composed of the above two parts, a radially extending edge 25 is allowed to be constructed on the outer end of the rotating shaft 24. During installation, the rotating shaft 24 on the sidewall of the rotating seat 3 is first inserted into the first through hole 13 of the first lower housing 1b, and then the first upper housing 1a is closed. This ensures that the sidewall of the first through hole 13 is fitted between the edge 25 and the sidewall of the rotating seat 3, and the socket unit 1, the terminal module 2, and the rotating seat 3 will not detach.

[0063] In addition, such as Figure 4As shown, a protective cover 6 is provided on the first terminal 21 or the second terminal 11. In this design, to ensure safety when using the expandable power supply module 100, a protective cover 6 is provided on the first terminal 21 or the second terminal 11. The protective cover 6 can close the terminal interface at the end, and can only be removed when plugging in. The protective cover 6 can be detachable and reusable, or it can be disposable, meaning it cannot be reattached after removal, thus encouraging users to avoid plugging and unplugging the expansion module after expansion is completed.

[0064] In such Figure 11 In another embodiment shown, the elastic pin assembly is constructed as an elastic element 40 disposed on the outer wall of the rotating shaft 22. A partial arch of the elastic element extends into the positioning groove 131 to circumferentially lock the socket unit 1, terminal module 2, and rotating seat 3. In this embodiment, the elastic pin assembly is simply an elastic element, which can be a spring sheet, spring wire, or a protrusion with material elasticity, such as a plastic protrusion. During the circumferential rotation of the socket unit 1 or terminal module 2 relative to the rotating seat 3, the arched portion of the elastic element is pressed into or out of the positioning groove, achieving circumferential positioning and adjustment.

[0065] Example 2:

[0066] Figure omitted. This embodiment provides a multi-dimensional adjustable power supply device, characterized by comprising multiple power supply modules connected in sequence, wherein the power supply modules are expandable power supply modules 100 as described in Embodiment 1. This solution assembles and connects multiple expandable power supply modules 100 into a power strip to achieve expandable arrangement; at the same time, each expandable power supply module 100 can be rotated to adjust its angle.

[0067] Example 3:

[0068] like Figure 12As shown, this embodiment provides another multi-dimensional adjustable power supply device, including a socket body 7. The socket body 7 includes multiple socket units 1 rotatably connected in sequence, and a power receiving module 70 rotatably connected to the last socket unit 1. Adjacent socket units 1 or socket units 1 and power receiving module 70 can rotate relative to each other and be circumferentially positioned based on a pivot 24. Furthermore, the power receiving module 70 is electrically connected to the multiple socket units 1, and conductive components pass through the rotatable connection part 22, so that the power receiving module 70 remains electrically connected when rotating relative to the socket units 1 or two adjacent socket units 1. The power receiving module 70 is provided with a second terminal 11. This solution also includes an expandable power supply module 100 as described in embodiment 1. The first terminal 21 of the terminal module 2 of the expandable power supply module 100 can be plugged into the second terminal 11 of the power receiving module 70. Based on the prior patents with announcement number CN219106708U and CN219106622U, this solution can be expanded using the aforementioned expandable power supply module 100.

[0069] exist Figure 12 In the further preferred embodiment shown, adjacent socket units 1 and socket units 1 and power receiving modules 70 are rotatably connected via rotating bases 3. The rotation axis 24 of the rotating base 3 and the socket units 1 / power receiving modules 70 on both sides is arranged relative to the width direction of the socket unit 1, and a through hole 20 for wiring is formed along the rotation axis 24 at the hinge. Conductive components pass through the rotating base 3 and the through hole, so that multiple socket units 1 and power receiving modules 70 remain electrically connected when rotating. Adjacent socket units 1 of the socket body 7 are rotatably connected via rotating bases 3, and the rotating base 3 and the socket units 1 on both sides can rotate relative to each other. In this way, the relative rotation angle between adjacent socket units 1 is larger, and the torsional flexibility of the entire power supply device is higher; it not only adapts to a wider range of environments, but also minimizes the space occupied by rotating and folding when stored. Figure 13 As shown, the distance between the two pivot points on the rotating base 3 is approximately equal to the thickness of the socket unit 1, so that the two socket units 1 can be stacked together after rotating along the rotating base 3. Based on the above scheme, it can be ensured that the two socket units 1 can be stacked together in the thickness direction when stored.
