[0001] This application relates to the field of electrical equipment technology, and more particularly to a socket assembly and a power strip. Background Technology

[0002] Power strips are common household devices, referring to multi-outlet sockets with power cords and plugs that can be moved around; they are also called power strips or extension cords. In related technologies, in addition to conductive hardware, power strips also incorporate safety shutters and other protective mechanisms, resulting in a relatively large thickness. In scenarios with high space requirements, such as modern minimalist home environments or compact office desks, their large size can appear obtrusive and reduce space utilization.

[0003] In view of this, embodiments of this application aim to provide a socket assembly and power strip that can reduce thickness and thus improve space utilization.

[0004] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0005] This application provides a socket assembly, including:

[0006] Mounting base;

[0007] A housing, the housing being disposed on the mounting base and movable relative to the mounting base in a first direction, the housing being provided with a set of sockets that mate with an external plug;

[0008] A movable element, disposed on the mounting base and located on the side of the housing facing the mounting base, is movable along the first direction when the plug is inserted into the socket assembly, the first direction being parallel to the insertion direction of the plug;

[0009] A linkage assembly is connected to the housing and the moving member respectively for driving the other of the housing and the moving member to move when one of the housing and the moving member moves, and the moving directions of the housing and the moving member are opposite.

[0010] In some embodiments, the linkage assembly includes a first link, a second link, and a third link connected in sequence, wherein the second link is rotatably connected to the mounting base, the first link is kinetically connected to the moving part, and the third link is kinetically connected to the housing.

[0011] In some embodiments, the first link, the second link, and the third link are a single integrated structure; or,

[0012] The first link, the second link, and the third link are separate structures.

[0013] In some embodiments, the rotation center line of the second link defines a first plane with the first direction, and the second link includes a first connecting portion and a second connecting portion located on both sides of the first plane. The first connecting portion is rotatably connected to the first link, and the second connecting portion is rotatably connected to the third link.

[0014] In some embodiments, the first link is curved, and the center of curvature of the first link is located on the side of the first link closer to the rotation center line of the second link.

[0015] In some embodiments, the third link is curved, and the center of curvature of the third link is located on the side of the third link closer to the rotation center line of the second link.

[0016] In some embodiments, the housing includes a main body and a first guide portion, the main body being provided with the insertion hole assembly, the first guide portion extending along the first direction, and the mounting base being provided with a second guide portion, the first guide portion cooperating with the second guide portion to guide the movement of the housing.

[0017] In some embodiments, the mounting base is provided with a third guide portion, and the movable member is provided with a fourth guide portion. The third guide portion and the fourth guide portion cooperate to guide the movement of the movable member.

[0018] In some embodiments, the mounting base includes a mounting body and an elastic element, the elastic element being disposed between the housing and the mounting body;

[0019] When the housing and the moving member move away from each other, the housing compresses the elastic member to cause the elastic member to undergo elastic deformation; the elastic member is able to restore its elastic deformation to cause the housing and the moving member to move closer to each other.

[0020] In some embodiments, the mounting base includes a mounting cover connected to the mounting body, a receiving groove defining a space between the mounting cover and the housing, and an elastic element disposed in the receiving groove.

[0021] In some embodiments, the socket assembly includes a conductive element disposed on the side of the movable member opposite to the socket group; the movable member is provided with a insertion groove and a clearance hole, the insertion groove having an abutment surface on the side opposite to the socket group for abutting the plug, and the clearance hole for avoiding the conductive element.

[0022] The socket assembly of this application embodiment features a linkage assembly that is connected to both the housing and a movable component. The movable component is positioned on the side of the housing furthest from the plug, allowing it to move along the plug's insertion direction when the plug is inserted, and simultaneously moving the housing in the opposite direction. After the plug is fully inserted, the internal circuitry of the socket assembly is activated, allowing external electrical appliances to function normally. At the same time, the housing moves a certain distance relative to the mounting base, thus shielding the plug's prongs. This prevents the prongs from being exposed when the socket assembly is powered on, ensuring safety. This design improves the safety of the socket assembly while reducing its thickness, saving space, increasing space utilization, enhancing aesthetics, portability, and user experience. Furthermore, the linkage assembly has a simple structure, is easy to mold, reduces costs, and improves reliability. Attached Figure Description

[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] This application provides a socket assembly.

[0041] Please see Figures 1 to 8 The socket assembly 100 includes a mounting base 10, a housing 20, a movable member 30, and a linkage assembly 40. The housing 20 is disposed on the mounting base 10 and is movable relative to the mounting base 10 in a first direction. The housing 20 has a socket assembly 21 that mates with an external plug 200. The movable member 30 is disposed on the mounting base 10 and located on the side of the housing 20 facing the mounting base 10, and is movable in the first direction parallel to the insertion direction of the plug 200 when the plug 200 is inserted into the socket assembly 21. The linkage assembly 40 is kinetically connected to both the housing 20 and the movable member 30, and is used to drive the other of the housing 20 and the movable member 30 to move when one of them moves, with the directions of movement of the housing 20 and the movable member 30 being opposite.

[0042] Please see Figures 5 to 6 Mounting bracket 10 is a frame component of socket assembly 100. Mounting bracket 10 can be used to mount other components of socket assembly 100.

[0043] Please see Figure 7 The housing 20 is a frame component of the socket assembly 100 and can enclose the internal components of the socket assembly 100 together with the mounting base 10.

[0044] Please see Figure 8Here, the movable member 30 is a movable component that moves along a first direction when the plug 200 is inserted into the socket group 21. The first direction is parallel to the insertion direction of the plug 200. In other words, the moving direction of the movable member 30 is parallel to the insertion direction of the plug 200.

[0045] The movable part 30 serves to fix the plug 200 and transmit power. When the plug 200 is inserted, the movable part 30 may trigger the linkage assembly 40.

[0046] Similarly, the housing 20 is also a movable component, capable of moving relative to the mounting base 10 in the first direction, and in the opposite direction to the movement of the movable component 30, that is, the movement direction of the housing 20 is parallel to the insertion direction of the plug 200.

[0047] For example, the housing 20 is disposed on one side of the mounting base 10 along the thickness direction of the socket assembly 100, that is, the first direction is the thickness direction of the socket assembly 100.

[0048] For example, when the plug 200 is not inserted, the housing 20 is in its lowest position, and the power strip is ultra-thin. At this time, the linkage assembly 40 is stationary, and the relative positions of the components are stable. When the plug 200 is inserted into the socket assembly 21, the moving member 30 moves in the same direction as the plug 200 is inserted, while the housing 20 moves in the opposite direction to the plug 200 is inserted. This increases the size of the socket assembly 100 along the first direction, allowing the housing 20 to cover the prongs 210 of the plug 200.

[0049] For example, when the plug 200 is pulled out of the socket assembly 21, the moving member 30 moves in the same direction as the plug 200 is pulled out, and the moving direction of the housing 20 is opposite to the plug 200 is pulled out, thereby reducing the size of the socket assembly 100 along the first direction.

[0050] The linkage assembly 40 is connected to the housing 20 and the moving part 30 respectively for transmission between the housing 20 and the moving part 30, so that the housing 20 and the moving part 30 move in opposite directions.

[0051] In other words, by setting the linkage assembly 40, the housing 20 and the moving part 30 can move in opposite directions, thereby changing the distance between the housing 20 and the mounting base 10, which improves the safety of the socket assembly 100 while reducing the thickness of the socket assembly 100.

[0052] It should be noted that the specific number of link assemblies 40 is not limited. For example, there may be multiple link assemblies 40, which are spaced apart.

[0053] Please see Figure 5In this embodiment of the application, there are two linkage assemblies 40, and two movable parts 30 are respectively connected to the two ends of the movable parts 30 along the second direction, and the first direction intersects the second direction.

[0054] It should be noted that in the embodiments of this application, "multiple" refers to any number of two or more.

[0055] In related technologies, the external dimensions of power strips are fixed. In addition to the conductive hardware, there are also protective mechanisms such as safety door modules inside the power strip, which makes the existing power strips relatively thick. In some scenarios with high space requirements, such as modern minimalist home environments and compact office desks, their large size will appear obtrusive and reduce space utilization.

[0056] The socket assembly 100 of this embodiment incorporates a connecting rod assembly 40, which is connected to both the housing 20 and the moving member 30. The moving member 30 is positioned on the side of the housing 20 furthest from the plug 200, allowing it to move along the insertion direction of the plug 200 when it is inserted, and simultaneously moving the housing 20 in the opposite direction to the moving member 30. After the plug 200 is fully inserted, the internal circuitry of the socket assembly 100 is activated, allowing external electrical appliances to function normally. Simultaneously, the housing 20 moves a certain distance relative to the mounting base 10, thus shielding the plug pins 210. This prevents the pins 210 from being exposed when the socket assembly is powered on, ensuring safety. This design improves the safety of the socket assembly 100 while reducing its thickness, saving space, enhancing space utilization and product aesthetics, making it more portable, and improving the user experience. Furthermore, the connecting rod assembly 40 has a simple structure, is easy to mold, reduces costs, and improves reliability.

[0057] It should be noted that the specific structure of the link assembly 40 is not limited here.

[0058] In some embodiments, please refer to Figure 2 The linkage assembly 40 includes a first linkage 41, a second linkage 42 and a third linkage 43 connected in sequence. The second linkage 42 is rotatably connected to the mounting base 10, the first linkage 41 is drive-connected to the moving part 30, and the third linkage 43 is drive-connected to the housing 20.

[0059] Here, the transmission connection between the first link 41 and the moving part 30 means that the first link 41 and the moving part 30 can be either fixedly connected or rotatably connected.

[0060] Similarly, the transmission connection between the third link 43 and the housing 20 means that the third link 43 and the housing 20 can be either fixedly connected or rotatably connected.

[0061] For example, when the plug 200 is inserted into the socket assembly 21, the moving member 30 is driven to move in the insertion direction of the plug 200. The moving member 30 drives the first link 41 to move, the first link 41 drives the second link 42 to rotate, the second link 42 drives the third link 43 to move, and the third link 43 drives the housing 20 to move in the opposite direction to the moving direction of the moving member 30, that is, the housing 20 moves in the direction in which the plug 200 is pulled out of the socket assembly 21.

[0062] In some embodiments, the first link 41, the second link 42, and the third link 43 are an integral structure.

[0063] This helps reduce the number of parts and improve assembly efficiency.

[0064] In some embodiments, the first link 41, the second link 42, and the third link 43 are separate structures.

[0065] Here, the first link 41, the second link 42, and the third link 43 can all be separate structures, that is, the first link 41, the second link 42, and the third link 43 are all independent parts; the first link 41 and the second link 42 can be an integral structure, while the third link 43 is an independent part; or the second link 42 and the third link 43 can be an integral structure, while the first link 41 is an independent part.

[0066] In some embodiments, please continue reading Figure 2 The rotation center line of the second link 42 and the first direction define a first plane. The second link 42 includes a first connecting part and a second connecting part located on both sides of the first plane. The first connecting part is rotatably connected to the first link 41, and the second connecting part is rotatably connected to the third link 43.

[0067] For example, a first rotating shaft 16 is provided on the second connecting rod 42, and the second connecting rod 42 is rotatably mounted on the first rotating shaft 16. The rotation center line of the second connecting rod 42 is the central axis of the first rotating shaft 16.

[0068] Alternatively, the mounting base 10 may have a first rotating shaft 16.

[0069] For example, the second link 42 includes a second pivot 421. Both the first connecting part and the second connecting part are provided with the second pivot 421, and are rotatably connected to the first link 41 and the third link 43 respectively through the second pivot 421.

[0070] For example, the housing 20 is provided with a third pivot 24, and the third link 43 is rotatably connected to the housing 20 through the third pivot 24.

[0071] For example, the movable member 30 is provided with a fourth pivot 32, and the first connecting rod 41 is rotatably connected to the movable member 30 through the fourth pivot 32.

[0072] In some embodiments, please continue reading Figure 2 The first link 41 is curved, and the center of curvature of the first link 41 is located on the side of the first link 41 closer to the rotation center line of the second link 42. That is, the first link 41 is bent toward the rotation center line of the second link 42.

[0073] In this way, on the one hand, the movement trajectory of the first link 41 can be reduced, that is, the movement space of the first link 41 can be reduced, which is conducive to improving the structural compactness of the socket assembly 100. In addition, it is also conducive to forming a limit between the first link 41 and the second link 42, thereby improving the reliability of the link assembly 40.

[0074] In some embodiments, please continue reading Figure 2 The third link 43 is curved, and the center of curvature of the third link 43 is located on the side of the third link 43 closer to the rotation center line of the second link 42. That is to say, the third link 43 is bent toward the rotation center line of the second link 42.

[0075] In this way, on the one hand, the movement trajectory of the third link 43 can be reduced, that is, the movement space of the third link 43 can be reduced, which is conducive to improving the structural compactness of the socket assembly 100. In addition, it is also conducive to forming a limit between the third link 43 and the second link 42, thereby improving the reliability of the link assembly 40.

[0076] In some embodiments, please refer to Figures 6 to 7 The housing 20 includes a main body 22 and a first guide 23. The main body 22 is provided with a socket group 21. The first guide 23 extends along a first direction. The mounting base 10 is provided with a second guide 14. The first guide 23 and the second guide 14 cooperate to guide the movement of the housing 20.

[0077] For example, one of the first guide portion 23 and the second guide portion 14 is a guide post, and the other of the first guide portion 23 and the second guide portion 14 is a guide groove. The guide post is inserted into the guide groove to guide the movement of the housing 20.

[0078] In this embodiment, by setting the first guide portion 23 and the second guide portion 14 in cooperation, it is beneficial to improve the stability and reliability of the movement of the housing 20.

[0079] For example, the mounting base 10 is also provided with a limiting post 17, which abuts against the side wall of the housing 20 to further limit the movement of the housing 20, thereby further improving the stability and reliability of the movement of the housing 20.

[0080] In some embodiments, please refer to Figures 5 to 8 The mounting base 10 is provided with a third guide part 15, and the moving part 30 is provided with a fourth guide part 31. The third guide part 15 and the fourth guide part 31 cooperate to guide the movement of the moving part 30.

[0081] For example, one of the third guide portion 15 and the fourth guide portion 31 is a guide protrusion, and the other of the third guide portion 15 and the fourth guide portion 31 is a guide groove. The guide protrusion is inserted into the guide groove to guide the movement of the moving member 30.

[0082] For example, both the guide protrusion and the guide groove extend along a first direction.

[0083] In this embodiment, by providing the third guide portion 15 and the fourth guide portion 31 in cooperation, it is beneficial to improve the stability and reliability of the movement of the moving part 30.

[0084] In some embodiments, please refer to Figures 2 to 4 The mounting base 10 includes a mounting body 11 and an elastic element 12, which is disposed between the housing 20 and the mounting body 11. When the housing 20 and the moving member 30 move away from each other, the housing 20 compresses the elastic element 12 to cause the elastic element 12 to undergo elastic deformation; the elastic element 12 can restore its elastic deformation to cause the housing 20 and the moving member 30 to move closer to each other.

[0085] It should be noted that the specific type of elastic element 12 is not limited here.

[0086] For example, the elastic element 12 is a spring, torsion spring, etc.

[0087] Here, an elastic element 12 is provided for the automatic reset of the housing 20. That is, after the socket assembly 100 is used and the plug 200 is unplugged, the housing 20 automatically resets, thereby reducing the thickness of the socket assembly 100.

[0088] When in use, when the plug 200 is inserted, it first passes through the socket group 21 and then enters the moving part 30. Under a certain pushing force, the plug 200 abuts against the moving part 30 and continues to move along the first direction under the action of the manual pushing force. The moving part 30 drives the housing 20 to move in the opposite direction of the moving part 30 through the connecting rod assembly 40 until it is in complete contact with the conductive part 50 to achieve good conduction. In addition, the housing 20 can block the plug pins 210 of the plug 200. When the plug 200 is pulled out, the elastic part 12 drives the housing 20 to automatically reset.

[0089] In other words, when the socket assembly 100 is not in use, the housing 20 is brought into contact with the mounting base 10 as close as possible under the elastic force of the elastic member 12, thereby reducing the thickness of the socket assembly 100.

[0090] When the plug 200 is pulled out, the moving part 30 loses pressure, and under the action of the elastic part 12, the connecting rod assembly 40 moves in the opposite direction, causing the housing 20 to descend and return to its initial ultra-thin state.

[0091] The conductive element 50 is used to connect the plug 200 to the internal circuit of the power strip, ensuring normal current conduction.

[0092] In some embodiments, please refer to Figures 3 to 5 The mounting base 10 includes a mounting cover 13, which is connected to the mounting body 11. A receiving groove 110 is defined between the mounting cover 13 and the housing 20, and an elastic member 12 is disposed in the receiving groove 110.

[0093] Here, the mounting cover 13 may have a receiving groove 110, the housing 20 may have a receiving groove 110, or the mounting cover 13 and the housing 20 may have a receiving groove 110 together.

[0094] To facilitate the installation of the elastic element 12, a receiving groove 110 is defined between the mounting cover 13 and the housing 20. The elastic element 12 is disposed within the receiving groove 110, which helps to improve the stability of the elastic element 12. One end of the elastic element 12 abuts against the mounting cover 13 along the axial direction, and the other end abuts against the housing 20.

[0095] For example, the mounting cover 13 is provided with a limiting post 17 that extends into the interior of the elastic member 12 to position the elastic member 12.

[0096] In some embodiments, please refer to Figures 2 to 4 The socket assembly 100 includes a conductive element 50, which is disposed on the side of the movable element 30 away from the socket group 21. The movable element 30 is provided with a plug groove 34 and a clearance hole 36. The side of the plug groove 34 opposite to the socket group 21 has an abutment surface 35 for abutting with the plug 200, and the clearance hole 36 is used to avoid the conductive element 50.

[0097] Here, when the plug 200 is inserted, it first passes through the socket group 21 and then enters the moving member 30. Under the action of a certain pushing force, the plug 200 abuts against the contact surface 35 of the moving member 30, and under the action of the human pushing force, the plug 200 continues to move along the first direction. The moving member 30 drives the housing 20 to move in the opposite direction of the moving member 30 through the connecting rod assembly 40. At the same time, the conductive member 50 extends into the clearance hole 36 until the conductive member 50 is in complete contact with the plug 200 to achieve good conductivity. In addition, the housing 20 can block the plug pins 210 of the plug 200. When the plug 200 is pulled out, the elastic member 12 drives the housing 20 to automatically reset.

[0098] The structure is simple. While the movable part 30 and the plug 200 can move, the conductive part 50 can also extend through the clearance hole 36 and make full contact with the plug 200 to achieve electrical connection.

[0099] This application also provides a power strip, which includes a socket assembly 100 according to any embodiment of this application.

[0100] Here, the number of socket components 100 can be one or more.

[0101] In the embodiments of this application, "multiple" refers to two or more items.

[0102] In embodiments where there are multiple socket assemblies 100, the conductive elements 50 in any two adjacent socket assemblies 100 are connected in series; wherein, the distance between two adjacent housings 20 can be flexibly set according to customer needs.

[0103] For example, the power strip also includes a housing, within which each socket assembly 100 is disposed.

[0104] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
