Description

Technical Field

[0001] This utility model relates to the field of plugs, and more particularly to a plug-reversible adapter. Background Technology

[0002] Currently, many digital device power adapters feature retractable prongs. These adapters offer both an exposed prong mode and a retracted, concealed mode. In the concealed mode, the adapter's overall shape is more regular and easy to store. However, existing adapters typically only offer one mode, meaning the prongs can only extend to one side of the adapter. Considering the adapter's large size, a single mode only adequately suits certain applications, while being less suitable for others. For example, setting the prongs to extend perpendicular to the adapter's length in the active mode allows for better compatibility with wall sockets, but connecting to a desktop socket occupies additional desktop space outside the socket, and the adapter's center of gravity may not fall directly onto the socket, potentially posing a safety risk to the connection. Therefore, to improve usability, it is necessary to develop adapters with two or more modes. Utility Model Content

[0003] The main purpose of this invention is to propose a plug-reversible adapter with two usage modes to adapt to different application scenarios.

[0004] To achieve the above objectives, this utility model provides a pin-reversible adapter, including a hollow housing. The housing includes an intersecting first wall and a second wall. The first wall is the first end wall of the housing in a first direction, and the second wall is the second end wall of the housing in a second direction. The first direction is orthogonal to the second direction. The adapter is characterized by further including a movable component disposed on the housing. The movable component can move relative to the housing in the first direction. The movable component includes a slider and a conductive element hinged to the slider. Both the slider and the conductive element are at least partially located inside the housing. The conductive element can also rotate along a plane defined by the first and second directions. The conductive element has a pin portion.

[0005] The housing has a first through slot through which the pins pass. The first through slot passes through the first wall and the second wall. The pin-reversible adapter has a first form, a second form and a third form. In the first form, the pins are located inside the housing. In the second form, the pins pass through the first through slot and out of the first wall. In the third form, the pins pass through the first through slot and out of the second wall.

[0006] As can be seen from the above scheme, the conductive component has two modes of movement: linear movement and rotation, enabling the adapter to have two different usage modes. In the second and third modes, the prongs can be moved to protrude from two orthogonal directions of the housing, thus allowing for adaptation to different application scenarios. Simultaneously, the adapter also has a first mode as a concealed mode, in which the prongs can be completely retracted into the housing for protection and to reduce the overall storage space required for the adapter. To ensure better adaptation to desktop sockets in the second mode, the first direction can be determined with reference to the length direction of the housing; to ensure better adaptation to wall sockets in the third mode, the second direction can be determined with reference to the width or thickness direction of the housing.

[0007] A further embodiment is that the conductive component has a protrusion at the third-direction end, the slider includes an outer portion located at the third-direction end, and the housing also includes a third wall facing each other in the third direction. The third wall has a guide groove on its inner side that cooperates with the protrusion and the outer portion. The guide groove has a straight section extending along the first direction and an arc-shaped section communicating with the straight section. The third direction is orthogonal to the first direction and the second direction.

[0008] As can be seen from the above scheme, the movable component achieves a movable connection with the housing by cooperating with the guide groove through the protrusion and external connection. This cooperation also restricts the movement of the conductive component and the slider, thereby guiding the adapter to switch modes. The straight section of the guide groove guides the linear movement of the slider and the conductive component, while the arc-shaped section guides the rotation of the conductive component.

[0009] A further proposed solution is that, in the first and second configurations, the protrusion is located within the straight-conducting segment, while in the third configuration, the protrusion is located within the arc-shaped segment.

[0010] As can be seen from the above scheme, the straight section can guide the adapter to switch between the first and second modes by cooperating with the external part and the protrusion, and the arc-shaped section can guide the adapter to switch between the second and third modes by cooperating with the protrusion.

[0011] A further option is to set enclosure ribs on the inner side of the third wall, and the guide groove is a closed area formed by the enclosure ribs.

[0012] As can be seen from the above scheme, configuring the guide groove in the form of enclosing ribs on the third wall does not reduce the structural strength of the third wall compared to directly recessing the guide groove on the third wall, and also helps to strengthen the fit between the moving components and the shell.

[0013] A further embodiment includes a fourth wall opposite to the second wall in a second direction, and the movable component includes an actuating member connected to the slider. A second through groove is provided on the fourth wall along a first direction. The actuating member includes a cap located outside the fourth wall and a rod that engages with the second through groove.

[0014] As can be seen from the above scheme, the introduction of the second through groove and the toggle member facilitates the linear movement of the slider by the user. When in use, the user can place their finger on the cap of the toggle member to move the slider.

[0015] A further embodiment includes a limiting structure, which prevents the toggle member from moving towards the side closer to the first wall in the first configuration, and also prevents the toggle member from moving away from the first wall in the second and third configurations.

[0016] As can be seen from the above solution, the introduction of a limiting structure can prevent the plug from retracting when the adapter is connected to the socket, ensuring a stable connection between the adapter and the socket, and also helping to maintain the first form.

[0017] A further embodiment is that the actuating element can move relative to the slider in a second direction. The rod has a limiting ring protrusion on its outer side with an outer diameter larger than the third dimension of the second through groove. A compression spring is sleeved on the rod. The first end of the compression spring abuts against the limiting ring protrusion, and the second end of the compression spring abuts against the slider. A limiting rib that cooperates with the limiting ring protrusion is provided on the inner side of the fourth wall at the end of the second through groove. In the first configuration, the side of the limiting ring protrusion closest to the first wall abuts against the limiting rib. In the second and third configurations, the side of the limiting ring protrusion away from the first wall abuts against the limiting rib. The limiting structure includes the limiting ring protrusion, the compression spring, and the limiting rib.

[0018] As can be seen from the above scheme, the movement restriction between the toggle and the housing can be achieved by using the limiting ring protrusion, the compression spring and the limiting rib. The user can unlock the movement restriction of the toggle at both ends of the second through slot by pressing the toggle, and the restriction can be restored after releasing the hand.

[0019] A further design involves providing a sleeve portion on the side of the slider near the fourth wall that fits with the clearance of the rod, with portions of both the rod and the compression spring located within the sleeve portion.

[0020] As can be seen from the above scheme, the slider can be connected to the actuating component through the sleeve, and the sleeve can cooperate well with the rod and the compression spring.

[0021] A further embodiment is that the conductive component includes two pins facing each other on the third side and a cross joint connecting the two pins. A hinge rod protrudes from the outer side of the cross joint, and two hinge lugs that cooperate with the hinge rod are provided at intervals on the side of the slider near the first wall.

[0022] As can be seen from the above scheme, both pins are indirectly hinged to the slider through the cross joint and the hinge rod. Compared with the case where both pins are directly hinged to the slider individually, this can improve the synchronicity of movement and the smoothness of rotation of the two pins.

[0023] A further embodiment is that, in the second configuration, the pin portion is perpendicular to the first wall and abuts against the first end of the first through slot; in the third configuration, the pin portion is perpendicular to the second wall and abuts against the second end of the first through slot.

[0024] As can be seen from the above scheme, in both usage modes, the two ends of the first through slot abut against the pins, which helps to maintain the vertical posture of the pins so that the adapter can be connected to the socket.

[0025] The plug-reversible adapter of this utility model has two usage modes with different plug positions, which can better adapt to different types of sockets. The plug can also be completely retracted into the housing to reduce the storage space required for the adapter, and the adapter is easy to switch between different modes.

Detailed Implementation

[0039] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0041] Existing adapters with a folding design typically only have one usage mode, meaning the prongs can only extend to one side of the adapter. Considering the large size of the adapter itself, adapters with a single usage mode cannot well adapt to different application scenarios. For example, setting the extension direction of the prongs to be perpendicular to the length of the adapter in the usage mode can better adapt to wall sockets, but connecting to a desktop socket will take up additional desktop space outside the socket, and the plumb bob projection of the adapter's center of gravity may not be on the socket, which may pose a certain risk to the stability of the connection.

[0042] Reference Figures 1 to 10 This utility model provides a plug-reversible adapter, including a hollow housing 100, which is generally cuboid in shape. An XYZ coordinate system is established based on the housing 100, where the Z-axis is parallel to the height direction of the housing 100. The Z-axis can be defined as parallel to the plumb line, specifically, the +Z-axis can be defined as the opposite direction of the plumb line. The X-axis and Y-axis are both orthogonal to the Z-axis, specifically, they can be two horizontally extending and orthogonal directions. Here, the length and width directions of the housing 100 are defined as the X-axis and Y-axis, respectively. Furthermore, the X-axis is defined as the first direction, the Z-axis as the second direction, and the Y-axis as the third direction.

[0043] The housing 100 includes an intersecting first wall 101 and a second wall 102. The first wall 101 is the X-axis (first direction) end wall of the housing 100, specifically the +X-axis end wall, and the second wall 102 is the Z-axis (second direction) end wall of the housing 100, specifically the -Z-axis end wall. The pin-reversible adapter also includes a movable component 200 disposed on the housing 100. The movable component 200 is movable relative to the housing 100 in the X-axis direction. The movable component 200 includes a slider 210 and a conductive element 220 hinged to the slider 210. Both the slider 210 and the conductive element 220 are at least partially located inside the housing 100. The conductive element 220 is also rotatable along the XZ plane and has a pin portion 221.

[0044] The housing 100 is provided with a first through groove 110 through which the pin portion 221 passes. The first through groove 110 passes through the first wall 101 and the second wall 102. The pin-reversible adapter has a first mode, a second mode and a third mode. In the first mode, the pin portion 221 is located inside the housing 100. In the second mode, the pin portion 221 passes through the first through groove 110 and exits the first wall 101. In the third mode, the pin portion 221 passes through the first through groove 110 and exits the second wall 102.

[0045] The conductive element 220 has both linear movement and rotational movement, giving the reversible plug adapter two different usage modes. The rotational movement mode determines its "reversible plug" characteristic. In the second and third usage modes, the plug portion 221 can be moved to protrude from the mutually orthogonal +X and -Z directions, thereby adapting to different application scenarios. Simultaneously, the reversible plug adapter also has a first hidden mode, in which the plug portion 221 can be completely retracted into the housing 100 for protection and to reduce the overall storage space required for the adapter. The reversible plug adapter of this embodiment has a larger dimension in the X-axis direction, thus it adapts well to desktop sockets in the second mode and to wall sockets in the third mode.

[0046] The conductive element 220 has a protrusion 222 at the Y-axis direction (third direction) end, the slider 210 includes an outer part 211 at the Y-axis direction end, and the housing 100 also includes a third wall 103 opposite to each other in the Y-axis direction. The third wall 103 has a guide groove 120 on its inner side that cooperates with the protrusion 222 and the outer part 211. The guide groove 120 has a straight guide section 121 extending in the X-axis direction and an arc-shaped section 122 communicating with the straight guide section 121.

[0047] The movable component 200 engages with the guide groove 120 via the protrusion 222 and the external connection 211 to achieve a movable connection with the housing 100. This engagement also restricts the movement of the conductive element 220 and the slider 210, thereby guiding the switching mode of the pin-reversible adapter. The straight section 121 of the guide groove 120 guides the linear movement of the slider 210 and the conductive element 220, while the arc-shaped section 122 guides the rotation of the conductive element 220.

[0048] In the first and second configurations, the protrusion 222 is located within the straight conductor section 121. In the third configuration, the protrusion 222 is located within the arc-shaped section 122. Furthermore, in all three configurations and during the corresponding configuration switching processes, the external connector 211 remains within the straight conductor section 121. The straight conductor section 121, in conjunction with the external connector 211 and the protrusion 222, guides the pin-reversible adapter to switch between the first and second configurations. The arc-shaped section 122, in conjunction with the protrusion 222, guides the pin-reversible adapter to switch between the second and third configurations.

[0049] The third wall 103 has an enclosing rib 130 on its inner side, and the guide groove 120 is a closed area formed by the enclosing rib 130. By configuring the guide groove 120 in the form of an enclosing rib 130 on the third wall 103, compared with directly recessing the guide groove 120 on the third wall 103, the wall thickness of the third wall 103 is not weakened, thus avoiding a reduction in its structural strength. From a design perspective, it is also easier to increase the Y-axis dimension of the guide groove 120, the outer part 211, and the protrusion 222, thereby helping to strengthen the fit between the movable component 200 and the housing 100.

[0050] In this embodiment, the enclosure rib 130 is a closed ring of convex ribs provided on opposite sides of two third walls 103. The enclosure rib 130 encloses and forms a closed section with an opening on the +Y axis direction or the -Y axis direction. This closed section can be regarded as a guide groove 120.

[0051] The housing 100 also includes a fourth wall 104 opposite to the second wall 102 in the Z-axis direction. The movable assembly 200 also includes a toggle member 230 connected to the slider 210. A second through groove 140 is provided on the fourth wall 104 along the X-axis direction. The toggle member 230 includes a cap 231 located outside the fourth wall 104 and a rod 232 that cooperates with the second through groove 140. The introduction of the second through groove 140 and the toggle member 230 facilitates the user's control of the linear movement of the slider 210. During use, the user can place their finger against the cap 231 of the toggle member 230 to move the slider 210. In this embodiment, the Y-axis dimension of the cap 231 is larger than the Y-axis dimension of the second through groove 140, and the surface of the cap 231 is provided with anti-slip texture to facilitate user operation.

[0052] The pin-reversible adapter also includes a limiting structure for preventing the toggle member 230 from moving toward the side closer to the first wall 101, i.e., the +X axis direction side, in the first configuration. The limiting structure is also used to prevent the toggle member 230 from moving toward the side farther from the first wall 101, i.e., the -X axis direction side, in the second and third configurations. The actuating member 230 can move relative to the slider 210 along the Z-axis direction. The rod 232 has a limiting ring protrusion 233 with an outer diameter larger than the Y-axis dimension of the second through groove 140 on its outer side. A compression spring 234 is sleeved on the rod 232. The first end of the compression spring 234 abuts against the limiting ring protrusion 233, and the second end of the compression spring 234 abuts against the slider 210. The inner side of the fourth wall 104 has a limiting rib 150 that cooperates with the limiting ring protrusion 233 at the end of the second through groove 140. In the first configuration, the limiting ring protrusion 233 abuts against the limiting rib 150 on the side closer to the first wall 101, i.e., the +X-axis side. In the second and third configurations, the limiting ring protrusion 233 abuts against the limiting rib 150 on the side farther away from the first wall 101, i.e., the -X-axis side. The above limiting structure includes the limiting ring protrusion 233, the compression spring 234, and the limiting rib 150.

[0053] By introducing a limiting structure, the pin portion 221 of the reversible adapter can be prevented from retracting when connected to the socket, ensuring a stable connection between the adapter and the socket. It also helps to maintain the concealed form, i.e., the first form. The limiting ring protrusion 233, the compression spring 234, and the limiting rib 150, as a relatively simple limiting structure, can limit the movement of the toggle member 230 and the housing 100 in the X-axis direction.

[0054] The user can release the movement restriction at one end of the second through groove 140 by pressing the cap 231 to move the actuating member 230 downward against the elastic force of the compression spring 234 until the limiting ring protrusion 233 is located on the -Z axis side of the corresponding limiting rib 150. After pushing the actuating member 230 to the other end of the second through groove 140 and releasing the pressure, the limiting ring protrusion 233 will move upward under the elastic force of the compression spring 234 until it coincides with the corresponding limiting rib 150 in the Z axis direction, thereby restoring the movement restriction of the actuating member 230. In this embodiment, the limiting rib 150 is an arc-shaped protrusion structure that roughly matches the shape of the limiting ring protrusion 233, and can fit and abut against the corresponding side of the limiting ring protrusion 233, thereby effectively restricting the movement of the actuating member 230.

[0055] The slider 210 has a sleeve portion 212 on the side near the fourth wall 104, which is in clearance fit with the rod portion 232. Both the rod portion 232 and the compression spring 234 are partially located inside the sleeve portion 212. The slider 210 can be connected to the actuating member 230 through the sleeve portion 212, and the sleeve portion 212 can cooperate well with the rod portion 232 and the compression spring 234.

[0056] The conductive component 220 includes two opposing pin portions 221 in the Y-axis direction and a cross joint 223 connecting the two pin portions 221. A hinge rod 224 protrudes from the outer side of the cross joint 223. The slider 210 has two hinge ears 213 spaced apart on the side near the first wall 101, which cooperate with the hinge rod 224. Both pin portions 221 are indirectly hinged to the slider 210 through the cross joint 223 and the hinge rod 224. Compared with the case where both pin portions 221 are directly hinged to the slider 210 individually, this improves the synchronicity of movement and the smoothness of rotation of the two pin portions 221.

[0057] In the second configuration, the pin portion 221 is perpendicular to the first wall 101 and abuts against the first end of the first through groove 110. In the third configuration, the pin portion 221 is perpendicular to the second wall 102 and abuts against the second end of the first through groove 110. The fact that the two ends of the first through groove 110 abut against the pin portion 221 in both configurations helps maintain the vertical orientation of the pin portion 221, facilitating the connection of the pin-reversible adapter to the socket.

[0058] The reversible plug adapter also includes an adapter interface 160 located on the -X axis side of the housing 100. This embodiment has two adapter interfaces 160, both of which are USB interfaces for connecting to the internal circuitry of the adapter (not shown in the figure). In both the second and third configurations, the plug portion 221 can be connected to the internal circuitry of the adapter.
