Description

Technical Field

[0001] This invention relates to the field of electrical devices, and particularly to sockets. Background Technology

[0002] The socket includes a cover, a base, a socket assembly, and a switch assembly. The socket assembly includes a socket located inside the base for inserting a plug. The switch assembly controls the power supply to and from the socket and includes a button; pressing the button activates or deactivates the switch assembly. The cover has a socket hole opposite the socket and a button through-hole opposite the button; the socket hole and the button through-hole are located at different positions on the cover.

[0003] Existing sockets often have the problem of the switch not being turned off when the plug is unplugged, posing a safety hazard. Summary of the Invention

[0004] In view of this, the present invention provides a socket that can solve the above-mentioned technical problems.

[0005] Specifically, the following technical solutions are included:

[0006] A socket comprising: a faceplate, a base, a socket assembly, a movable cover, and a switch.

[0007] The face cover and the base are connected and cooperate to form a socket cavity, and the socket assembly and the switch are both located inside the socket cavity;

[0008] The face cover has a through hole, and the movable cover has a socket. The movable cover is movably connected to the face cover through the through hole. The movable cover is configured to allow a plug to be inserted into the socket of the socket assembly through the socket and to be pressed down by the plug.

[0009] The switch is electrically connected to the socket assembly. The switch is configured to be triggered by the downwardly moving movable cover to perform an opening and closing operation, thereby energizing or de-energizing the socket assembly.

[0010] In some possible implementations, the switching element includes a connected switching structure and a pressing structure, the switching structure having two terminals, one of which is connected to the live wire of the power supply line of the socket, and the other terminal is electrically connected to the live wire of the socket assembly.

[0011] The pressing structure includes a telescopic head, which is configured such that the telescopic head can be driven by the downwardly moving movable cover to perform a telescopic movement, and transmit the telescopic movement to the switch structure, so that the switch structure performs the opening and closing operation.

[0012] In some possible implementations, the pressing structure is further configured to lock the telescopic head when the plug is inserted into place by pressing the movable cover, thereby keeping the switch structure energized; and to release the telescopic head by pressing the movable cover again, thereby driving the movable cover upward when the telescopic head extends, thereby keeping the switch structure de-energized.

[0013] In some possible implementations, the pressing structure is a heart-shaped groove pressing structure, a ratchet pressing structure, or an elephant trunk buckle pressing structure.

[0014] In some possible implementations, the switch is located below the movable cover, the bottom of the movable cover abuts against or connects to the telescopic head, and the direction of movement of the movable cover is the same as the direction of extension and retraction of the telescopic head.

[0015] In some possible implementations, the direction of movement of the movable cover is perpendicular to the direction of extension and retraction of the telescopic head;

[0016] The movable cover and the telescopic head switch their direction of movement via a wedge mechanism.

[0017] In some possible implementations, the lower end of the movable cover and the end of the telescopic head facing the movable cover have the wedge mechanism.

[0018] In some possible implementations, the socket further includes a transmission member disposed between the movable cover and the telescopic head, a first end of the transmission member being connected to the telescopic head, and a second end of the transmission member having the wedge mechanism at the lower end of the movable cover.

[0019] In some possible implementations, the movable cover has a stop structure to prevent the movable cover from disengaging from the through hole.

[0020] In some possible implementations, the switch is located on one side of the socket assembly, and elastic supports are provided around the other sides of the socket assembly.

[0021] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0022] The socket provided in this embodiment of the invention allows the switching element to control the power supply and de-energization of the socket by interacting with a movable cover. When the plug of an external appliance is inserted into the socket's socket assembly, the plug is inserted into the socket assembly through a hole on the movable cover. The downward movement of the plug simultaneously presses down on the movable cover, causing it to move downward as well. The downward movement of the movable cover triggers the switching element, opening it and energizing the socket assembly. When the plug needs to be unplugged, pressing the plug again triggers the switching element again, closing it and de-energizing the socket assembly. Therefore, the design of the movable cover and the switching element allows the plug to directly participate in the power supply and de-energization of the socket. Pressing the plug inserts it into the socket, energizing it; pressing it again de-energizes it. The switching element pushes the movable cover up, disengaging the plug from the socket assembly, making it easier to unplug. This provides the socket provided in this embodiment of the invention with the advantages of readily available power and power-off when the plug is unplugged, resulting in higher operational safety and easier plug removal.

These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] In the embodiments of this invention, the directional terms such as "upper," "lower," and "side" are all based on the orientation corresponding to the assembly state of the socket. Specifically, the orientation of the faceplate is "upper" or "top," the orientation of the base is "lower" or "bottom," the direction of the plug insertion into the socket is defined as downward, and the direction of the plug removal from the socket is defined as upward. These directional terms are used only to more clearly describe the relationship between structures, not to describe absolute orientations.

[0056] It should be noted that the socket includes functional components, which in turn include a socket assembly. The socket assembly includes a socket and a protective door located on top of the socket. Therefore, in this embodiment of the invention, the entire assembly consisting of the socket and the protective door is referred to as the socket assembly.

[0057] Currently, sockets frequently experience situations where the switch remains active even after the plug is unplugged, posing a safety hazard. To address this technical problem, this invention provides a socket, such as... Figure 1 and Figure 2 As shown, the socket includes: a faceplate 1, a base 2, a socket assembly 3, a movable cover 4, and a switch 5. Combined with... Figure 3 It can be seen that the cover 1 and the base 2 are connected and cooperate to form the socket cavity, and the socket assembly 3 and the switch 5 are both located inside the socket cavity.

[0058] The faceplate 1 has a through hole 10, and the movable cover 4 has a socket 40. The movable cover 4 is movably connected to the faceplate 1 through the through hole 10, so that the movable cover 4 can reciprocate in the up-down direction relative to the faceplate 1. The movable cover 4 is configured to allow the plug to be inserted into the socket of the plug assembly 3 through the socket 40, and to move downward by being pressed by the plug.

[0059] The movement trajectory of the movable cover 4 includes an upper stop position, a first lower stop position, and a second lower stop position. When the socket is in its normal state, the plug is not inserted, and the movable cover 4 is stable at the upper stop position. When the plug is inserted into the socket and the movable cover 4 is pressed down, the movable cover 4 can move from the upper stop position to the first lower stop position. When the plug is pressed further while in the power-on state, the movable cover 4 can move from the first lower stop position to the second lower stop position.

[0060] Specifically, in this embodiment of the invention, the switch 5 is electrically connected to the socket assembly 3. The switch 5 is configured to be triggered by the downwardly moving movable cover 4 to perform opening and closing operations, thereby energizing or de-energizing the socket assembly 3.

[0061] The socket provided in this embodiment of the invention allows the switch 5 to control the power supply and de-energization of the socket by interacting with the movable cover 4. When the plug of an external appliance is inserted into the socket's socket assembly 3, the plug is inserted into the socket assembly 3 through the socket hole 40 on the movable cover 4. The downward movement of the plug simultaneously presses down on the movable cover 4, causing it to move downward as well. The downward movement of the movable cover 4 triggers the switch 5, opening the switch 5 and thus energizing the socket assembly 3. When it is necessary to unplug the plug, pressing the plug again causes the downward movement of the movable cover 4 to trigger the switch 5 again, closing the switch 5 and thus de-energizing the socket assembly 3. As can be seen, based on the design of the movable cover 4 and the switch 5, the plug directly participates in the power supply and de-energization of the socket. Pressing the plug inserts it into the socket, and the socket is powered on. Pressing the plug again de-energizes the socket. The switch 5 pushes the movable cover 4 to pop up, allowing the plug to disengage from the plug sleeve assembly 3. This makes it easier to pull the plug out of the socket. As a result, the socket provided by this embodiment of the invention has the advantages of being able to access power as needed and keeping the power off when the plug is pulled out. It has higher operational safety and the plug is easier to pull out.

[0062] Then unplug the plug from the socket. This gives the socket provided by the present invention the advantage of being able to draw power whenever needed and keeping the power off when the plug is unplugged, thus providing higher operational safety.

[0063] In some examples of the present invention, the switch 5 includes a switch structure and a pressing structure connected together. The switch structure has two terminals, one of which is connected to the live wire of the power supply line of the socket, and the other terminal is electrically connected to the live wire of the socket assembly 3.

[0064] Through the design of the switch structure, an electrical connection between the switch element 5 and the socket assembly 3 can be achieved.

[0065] The pressing structure includes a telescopic head 51, which is configured such that the telescopic head 51 can be driven by the downwardly moving movable cover 4 to perform telescopic movement, and transmits the telescopic movement to the switch structure, so that the switch structure can perform opening and closing operations.

[0066] The above-described design of the pressing structure with telescopic head 51 enables it to perform a pressing-type telescopic movement, transmitting the driving force from the movable cover 4 to the switch structure, causing the switch structure to perform opening and closing operations, and the telescopic head 51 automatically resets after the plug is pulled out.

[0067] In some examples, the pressing mechanism is further configured to lock the telescopic head 51 when the plug is inserted in place by pressing the movable cover 4, thereby keeping the switch structure energized; and to release the telescopic head 51 by pressing the movable cover 4 again, thereby driving the movable cover 4 upward when the telescopic head 51 extends, thereby keeping the switch structure de-energized. Here, "plug inserted in place" means that the plug pin is fully inserted into the socket, enabling normal power supply.

[0068] When the plug of an external appliance is inserted into the socket assembly 3, the plug is inserted into the socket assembly 3 through the socket 40 on the movable cover 4. The downward movement of the plug can simultaneously press the movable cover 4, causing it to move downward as well. The downward movement of the movable cover 4 can drive the telescopic head 51 to compress. The telescopic head 51 locks when the plug is fully inserted to ensure that the plug pin is stably inserted into the socket assembly 3. At the same time, the socket is powered on.

[0069] Press the plug down again, and the movable cover 4 moves further down. The telescopic head 51 can be driven by the downwardly moving movable cover 4 to release the lock. The released telescopic head 51 performs an extension and reset movement, and during the extension movement, it drives the movable cover 4 to move upward and push the plug, so that the plug can be smoothly pulled out of the socket assembly 3. At the same time, the socket is de-energized.

[0070] As can be seen, by designing the structure of the switch 5 as described above, it is possible not only to control the power supply and de-energization of the socket, but also to facilitate the easy removal of the plug from the socket assembly 3. In particular, the socket automatically turns on when the plug is inserted and automatically turns off when the plug is removed, making operation more convenient.

[0071] As can be seen above, for the pressing structure of the switch 5, the telescopic head 51 has a first stop position and a second stop position in its extension stroke. When the switch 5 is in normal condition, the telescopic head 51 is located at the first stop position (at this time, the movable cover 4 is at the upper stop position). When the telescopic head 51 is pressed, the telescopic head 51 can move from the first stop position to the second stop position and lock at the second stop position (at this time, the movable cover 4 is at the first lower stop position). When the telescopic head 51 is pressed again (at this time, the movable cover 4 is at the second lower stop position), the switch 5 can automatically release the lock, so that the telescopic head 51 performs an extension and reset movement, and the telescopic head 51 resets from the second stop position to the first stop position.

[0072] All switch components 5 that satisfy the above-described switch structure and pressing structure are applicable to embodiments of the present invention. For example, some pressing structures applicable to embodiments of the present invention include, but are not limited to: heart-shaped groove pressing structure, ratchet pressing structure, or elephant trunk buckle pressing structure.

[0073] A push-button switch is a switching device with a heart-shaped groove pressing structure or a ratchet pressing structure. In some examples, the push-button switch is used as switch element 5, that is, switch element 5 is a push-button switch, and the button of the push-button switch is the telescopic head 51.

[0074] The push-button switch not only fulfills the above-mentioned functions of the switch component 5, but also has a small size. Using the push-button switch as the switch component 5 involved in the embodiments of the present invention not only realizes the effective use of existing devices, but also eliminates the need to manufacture new switch components 5, which helps to simplify the manufacturing process of the socket.

[0075] In some examples, the housing of the switch 5 is fixed to the faceplate 1 or the base 2. For example, the housing of the switch 5 is fixed to the inside of the base 2 by means of screw connection, snap-fit, riveting, pin connection, adhesive, etc.

[0076] As attached Figure 1 As shown, the base 2 has a fixing bracket 20 with screw holes. Screws are used to pass through the holes in the housing of the switch component 5 and thread them into the screw holes to fix the housing of the switch component 5 to the fixing bracket 20. By setting the fixing bracket 20, not only is it convenient to fix the switch component 5 in the base 2, but it is also convenient to control the position of the switch component 5 in the base 2 to a suitable position so that it can easily make direct or indirect contact with the movable cover 4.

[0077] In some implementations, see Figure 1 and Figure 3The switch 5 is located below the movable cover 4. The bottom of the movable cover 4 abuts against or connects to the telescopic head 51. The movement direction of the movable cover 4 is the same as the telescopic movement direction of the telescopic head 51, both moving in the up and down direction. In this way, the switch 5 is arranged in the vertical direction.

[0078] See Figure 3 When the movable cover 4 is pressed down by the plug, the telescopic head 51 is simultaneously pressed down by the movable cover 4, compressing downwards to allow the plug to be smoothly inserted into the socket assembly 3, thus energizing the socket. Pressing the plug again de-energizes the socket, causing the telescopic head 51 to extend upwards, and the movable cover 4 also moves upwards to reset, pushing the plug to disengage smoothly from the socket assembly 3.

[0079] To ensure that the movable cover 4 does not disengage from the through hole 10 when it moves up and down, in some examples, the movable cover 4 has a stop structure 430, which is used to prevent the movable cover 4 from disengaging from the through hole 10.

[0080] The stop structure 430 can be located on the outer wall of the movable cover 4, for example, in the form of a protrusion, so that it abuts against the bottom wall of the cover 1 located on the side of the through hole 10.

[0081] Based on the above implementation methods, some applicable specific structures of the movable cover 4 are illustrated by example, as shown in the appendix. Figure 4 As shown, the movable cover 4 includes a first cover body 411 and a first transmission part 412, with the first transmission part 412 connected to the bottom of the first cover body 411. The first cover body 411 can move up and down through the through hole 10; the first transmission part 412 abuts against or connects to the telescopic head 51 of the switch 5.

[0082] For example, the first cover portion 411 includes: a cover top wall and a cover side wall, the cover side wall is connected to the lower end of the cover top wall and extends downward, such that the cover top wall and the cover side wall cooperate to form a cover cavity, and the insertion hole 40 is formed on the cover top wall.

[0083] The shapes of the top wall and side walls of the cover are adapted to each other. Taking the structure of the top wall of the cover as an example, the shape of the top wall of the cover includes, but is not limited to, circles, ellipses, rectangles, hexagons, etc. Correspondingly, the shape of the through hole 10 on the cover 1 is also circles, ellipses, rectangles, hexagons, etc. The first cover part 411 is fitted with the through hole 10 on the cover 1 with a clearance, so that the movable cover 4 can only move in the vertical direction.

[0084] In addition, the above-mentioned structural design of the first cover portion 411 makes it adaptable to various types of plugs, and plugs of various shapes can make good surface-to-surface contact with the top wall of the first cover portion 411.

[0085] The first transmission part 412 is located at the bottom of the first cover part 411 so that the first transmission part 412 can directly contact the telescopic head 51 of the switch 5.

[0086] The first transmission part 412 and the telescopic head 51 can be abutted together. This method makes the assembly of the movable cover 4 and the switch 5 simpler and facilitates the assembly and disassembly of the socket.

[0087] The first transmission part 412 and the telescopic head 51 can also be connected. This method simplifies the structure of the movable cover 4, allowing the movable cover 4 to avoid detaching from the socket cavity without the need for a stop structure 430. In this embodiment of the invention, the volume of the cover cavity of the movable cover 4 is greater than or equal to the volume of the insert assembly 3.

[0088] Combination Figure 3 It can be seen that when the first transmission part 412 is located on the bottom outer side of the first cover part 411, the volume of the cover cavity is equal to the volume of the insert assembly 3, and the cover cavity can just accommodate the insert assembly 3, which helps to reduce the volume of the first cover part 411.

[0089] When the first transmission part 412 is directly connected to the bottom wall of the first cover part 411 (not shown in the figure), the first transmission part 412 is located below the first cover part 411, so that the volume of the cover cavity is larger than the volume of the insert assembly 3, in order to accommodate the telescopic head 51 located on one side of the insert assembly 3. In this way, a stop structure 430 can be arranged on the first cover part 411 so that the movable cover 4 stops at the upper stop position.

[0090] As attached Figure 4 As shown, the first transmission part 412 is in the shape of a ring plate. The first transmission part 412 is arranged in a circle around the outside of the first cover part 411. The first transmission part 412 protrudes from the bottom of the outer side wall of the first cover part 411 in the form of a flange. The bottom wall of the first transmission part 412 abuts against the telescopic head 51 of the switch member 5. The top wall of the first transmission part 412 serves as a stop structure 430 to abut against the bottom wall of the cover 1 located on the side of the through hole 10.

[0091] When the telescopic head 51 is unlocked and extends upward, the movable cover 4 moves upward together until the movable cover 4 returns to the upper stop position. At this time, the top wall of the first transmission part 412 of the movable cover 4 abuts against the bottom wall of the cover 1, so that the movable cover 4 stops at the upper stop position.

[0092] The first transmission part 412 combines a transmission structure and a stop structure 430, which helps to simplify the structure of the movable cover 4.

[0093] For example, the first transmission part 412 may include, but is not limited to, an annular plate shape, a rectangular annular plate shape, etc. Furthermore, the area of ​​the first transmission part 412 that contacts the telescopic head 51 may be larger than the area of ​​other areas.

[0094] The arrangement of the first transmission part 412 with the above-described structure on the movable cover 4 not only simplifies the structure of the movable cover 4 but also simplifies its manufacturing process. The movable cover 4 can be manufactured using a simple one-piece molding process. Of course, it is not excluded that the first transmission part 412 may be arranged only at a specific position on the outer side of the first cover body 411, so that the first transmission part 412 is not arranged in a circle around the first cover body 411.

[0095] As mentioned above, the first transmission part 412 and the telescopic head 51 can be either abutting each other or connected. In order to make the interaction between the movable cover 4 and the telescopic head 51 more reliable, the first transmission part 412 and the telescopic head 51 are connected.

[0096] As a simple and reliable method, the first transmission part 412 is connected to the shaft hole of the telescopic head 51. One of the first transmission part 412 and the telescopic head 51 has a fixed shaft 81, and the other has a fixed hole 82. The fixed shaft 81 is tightly inserted into the fixed hole 82, achieving a stable connection between the two. For example, as shown in the attached... Figure 1 and attached Figure 4 As shown, the lower end of the first transmission part 412 is connected to a fixed shaft 81, and the telescopic head 51 has a fixed hole 82.

[0097] In other implementations, such as the appendix Figure 5 As shown, the movement direction of the movable cover 4 is perpendicular to the extension and retraction direction of the telescopic head 51. The movable cover 4 and the telescopic head 51 switch their movement directions through a wedge mechanism. The movable cover 4 moves vertically, while the telescopic head 51 moves horizontally. In this configuration, the switch 5 is arranged horizontally.

[0098] The wedge mechanism can convert the downward movement of the movable cover 4 into the compression movement of the telescopic head 51, and the extension movement of the telescopic head 51 into the upward movement of the movable cover 4. The directions of the compression and extension movements of the telescopic head 51 are both horizontal.

[0099] The wedge mechanism has the advantages of high transmission efficiency, simple structure and easy manufacturing. The wedge mechanism can not only help to pull out the plug, but also help to insert the plug into the socket, making the plug insertion and removal more effortless and smooth, and improving the user experience.

[0100] In some examples, a wedge mechanism is disposed between the lower end of the movable cover 4 and the end of the telescopic head 51 facing the movable cover 4. This wedge mechanism includes a first wedge surface and a second wedge surface or a slider. For example, the lower end of the movable cover 4 has a first wedge surface, and the end of the telescopic head 51 has a slider or a second wedge surface; or, the end of the telescopic head 51 has a first wedge surface, and the lower end of the movable cover 4 has a slider or a second wedge surface.

[0101] In this example, either the first wedge surface and the second wedge surface are fitted together to form a wedge mechanism, or the first wedge surface is fitted together with the slider to form a wedge mechanism. Both methods can achieve the conversion of the movement direction of the movable cover and the telescopic head, and assist in the removal of the plug.

[0102] In other examples, such as the appendix Figure 5 As shown, the socket also includes a transmission member 6 disposed between the movable cover 4 and the telescopic head 51. The first end of the transmission member 6 is connected to the telescopic head 51, and the wedge mechanism is disposed between the second end of the transmission member 6 and the movable cover 4.

[0103] For example, the socket assembly 3, the transmission member 6, and the switch member 5 are arranged sequentially within the socket cavity along a direction parallel to the faceplate 1. The transmission member 6 occupies only the portion of the socket cavity located on one side of the socket assembly 3, thus not increasing the thickness of the socket, and also serves to assist in the insertion and removal of the plug.

[0104] For the wedge mechanism located at the second end of the transmission member 6 and the lower end of the movable cover member 4, as shown in the attached... Figure 6 Appendix Figure 7 and attached Figure 8 As shown, the first wedge surface 71 is located at the second end of the transmission member 6, and the second wedge surface 72 is located at the lower end of the movable cover member 4.

[0105] See Figure 8 The first wedge surface 71 has an upper end and a lower end, and the first wedge surface 71 gradually slopes downward from its upper end to its lower end. The upper end of the first wedge surface 71 is closer to the telescopic head 51 than its lower end. Correspondingly, the second wedge surface 72 is located at the lower end of the first transmission part 412 of the movable cover 4. The inclination direction of the second wedge surface 72 is the same as that of the first wedge surface 71. The second wedge surface 72 also has an upper end and a lower end, and the second wedge surface 72 gradually slopes downward from its upper end to its lower end.

[0106] like Figure 6 As shown, when the plug is not inserted into the socket, and the movable cover 4 is in the upper stop position, the first wedge surface 71 and the second wedge surface 72 are in complete contact with the ground surface. Figure 7As shown, when the plug is inserted into the socket, the plug presses down on the movable cover 4, causing the movable cover 4 to move downward from the upper stop position to the first lower stop position. The downward-moving second wedge surface 72 moves along the first wedge surface 71, thereby driving the transmission component 6 to move away from the movable cover 4, thereby compressing the telescopic head 51, causing the telescopic head 51 to move and lock at the second stop position. Finally, the movable cover 4 moves to the first lower stop position, and the lower part of the first wedge surface 71 abuts against the upper part of the second wedge surface 72, facilitating the insertion of the plug.

[0107] When it is necessary to unplug the plug from the socket, press the plug again. The movable cover 4 continues to move from the first lower stop position to the second lower stop position. The downward-moving second wedge surface 72 moves along the first wedge surface 71, driving the transmission component 6 to continue moving away from the movable cover 4, thereby compressing the telescopic head 51 again and releasing it from its lock. Subsequently, the first wedge surface 71 moves along the second wedge surface 72, and the upper end of the first wedge surface 71 gradually approaches the movable cover 4, driving the movable cover 4 to move from the first lower stop position to the upper stop position, while simultaneously pushing the plug to assist in unplugging it.

[0108] As a simple and reliable method, the transmission component 6 and the telescopic head 51 are connected by a shaft hole. One of the transmission component 6 and the telescopic head 51 has a fixed shaft 81, and the other has a fixed hole 82. The fixed shaft 81 is tightly inserted into the fixed hole 82 to achieve a stable connection between the two.

[0109] For example, as shown in the appendix Figure 8 As shown, a fixing hole 82 is provided at one end of the telescopic head 51 facing the transmission member 6, and a fixing shaft 81 is connected to the first end of the transmission member 6 facing the telescopic head 51.

[0110] Combined with appendix Figure 9 The structure of some applicable transmission components 6 is described by way of example. The transmission component 6 includes a main body 61, a first side 62 and a second side 63. The first side 62 and the second side 63 are respectively connected to and cooperate with the opposite sides of the main body 61 to form a receiving cavity for accommodating at least a portion of the insert assembly 3.

[0111] The first inclined wedge surface 71 is disposed at the upper end of the main body 61, the first side part 62, and the second side part 63, such as Figure 9 As shown, the length of the first wedge surface 71 arranged at the top of the main body 61 is less than the length of the first wedge surface 71 arranged at the top of the first side 62 and the second side 63. The first wedge surface 71 arranged at the top of the main body 61 only provides one end of the sliding trajectory, while the first wedge surface 71 arranged at the top of the first side 62 and the second side 63 provides the entire sliding trajectory.

[0112] The end of the main body 61 facing the telescopic head 51 abuts against or connects to the telescopic head 51, for example, with an attached... Figure 9 The main body 61 is shown to be connected to a fixed shaft 81 at one end, and a fixed hole 82 is provided at the corresponding end of the telescopic head 51. The fixed shaft 81 is adapted to be inserted into the fixed hole 82.

[0113] The receiving cavity of the transmission member 6 is vertically continuous, and the end facing the socket assembly 3 is open to allow the socket assembly 3 to enter or exit the receiving cavity relative to the transmission member 6. When no plug is inserted into the socket, part of the socket assembly 3 is accommodated inside the receiving cavity of the transmission member 6 to ensure that the first wedge surface 71 on the transmission member 6 is completely abutted against the second wedge surface 72 on the movable cover 4. When the transmission member 6 is driven away from the socket assembly 3 by the movable cover 4, the socket assembly 3 can be dislodged from the receiving cavity.

[0114] To make the horizontal movement of the transmission member 6 smoother, the bottom wall of the fixed bracket 20 facing the base 2 of the transmission member 6 is made into a smooth plane, for example, so that the transmission member 6 moves horizontally along the fixed bracket 20. Here, the bottom wall of the transmission member 6 refers to the bottom walls of its main body 61, first side 62 and second side 63.

[0115] Furthermore, a reinforcing structure 64 is arranged on the end of the main body 61 away from the telescopic head 51. This reinforcing structure 64 may be, for example, multiple reinforcing ribs (with a first wedge surface 71 arranged at the top of the reinforcing rib). This structural design of the transmission component 6 makes the internal structure of the socket more compact, which is conducive to miniaturization of the socket and simplifies the manufacturing process.

[0116] To ensure that the movable cover 4 does not disengage from the through hole 10 during vertical movement, in some examples, the movable cover 4 has a stop structure 430 to prevent it from disengaging from the through hole 10. For example, the stop structure 430 is connected to the outer wall of the movable cover 4, and the top wall of the stop structure 430 abuts against the bottom wall of the cover 1 located on the side of the through hole 10 to stop the upward movement of the movable cover 4, stopping it at the upper stop position.

[0117] Based on the above implementation methods, some applicable specific structures of the movable cover 4 are illustrated by example, as shown in the appendix. Figure 10 and attached Figure 11 As shown, the movable cover 4 includes: a second cover portion 421 and a second transmission portion 422, the second transmission portion 422 being connected to the bottom of the second cover portion 421; the second cover portion 421 being able to move up and down through the through hole 10; and the second transmission portion 422 being abutted against or connected to the second end of the transmission member 6.

[0118] For example, the second cover portion 421 includes a top wall and a side wall. The side wall is connected to the lower end of the top wall and extends downward, such that the top wall and side wall cooperate to form a cover cavity. The insertion hole 40 is formed on the top wall. The shapes of the top wall and side wall are adapted to each other. Taking the structure of the top wall as an example, the shape of the top wall includes, but is not limited to, a circle, an ellipse, a rectangle, a hexagon, etc. Correspondingly, the shape of the through hole 10 on the cover 1 is a circle, an ellipse, a rectangle, a hexagon, etc. The through hole 10 on the cover 1 is clearance-fitted with the second cover portion 421 so that the movable cover 4 can only move in the vertical direction.

[0119] In addition, the above-mentioned structural design of the second cover portion 421 makes it adaptable to various types of plugs, and plugs of various shapes can make good surface-to-surface contact with the top wall of the second cover portion 421.

[0120] The second transmission part 422 is located at the bottom of the second cover part 421 so that the second transmission part 422 can contact and interact with the transmission member 6. The cooperation method between the second transmission part 422 and the transmission member 6 can be referred to the cooperation method between the movable cover 4 and the transmission member 6 described above.

[0121] In some examples, the second transmission part 422 is located on the bottom outer side of the second cover part 421. The second transmission part 422 protrudes from the outer side wall of the second cover part 421, so that the volume of the cover cavity is equal to the volume of the insert assembly 3. The cover cavity can just accommodate the insert assembly 3, which helps to reduce the volume of the second cover part 421.

[0122] In some examples, when the second transmission part 422 is connected to the bottom wall of the second cover part 421, that is, the second transmission part 422 is only located below the second cover part 421 and does not protrude from the outer side wall of the second cover part 421, so that the volume of the cover cavity is larger than the volume of the insert assembly 3.

[0123] As a simple implementation method, as shown in the appendix Figure 10 Or attach Figure 13 As shown, the second transmission part 422 is in the shape of a skirt plate, and the second transmission part 422 is arranged in a circle around the outside of the second cover part 421; the top wall of the second transmission part 422 serves as the aforementioned stop structure 430.

[0124] The second transmission part 422 protrudes from the bottom of the outer side wall of the second cover part 421. The lower end of the second transmission part 422 abuts against or connects with the transmission member 6. The top wall of the second transmission part 422 can serve as the aforementioned stop structure 430 to abut against the bottom wall of the cover 1 located on the side of the through hole 10.

[0125] The second cover portion 421 is clearance-fitted with the through hole 10 on the cover 1. The second transmission portion 422 protrudes from the outer side wall of the second cover portion 421, so that the second transmission portion 422 is located on one side of the through hole 10 on the cover 1. The top wall of the second transmission portion 422 serves as a stop structure 430, so that the second transmission portion 422 combines a transmission structure and a stop structure 430, which helps to simplify the structure of the movable cover 4. Of course, the same stop effect can also be achieved by arranging the stop structure 430 on the aforementioned wedge surface.

[0126] The second transmission part 422 has a certain length in the vertical direction so that a second inclined wedge surface 72 with a certain inclined length can be arranged at its lower end.

[0127] In some examples, such as the attached Figure 11 As shown, the second transmission part 422 is rectangular in shape and includes two opposing first sidewalls 4221 and two opposing second sidewalls 4222. The second wedge surface 72 is disposed at the lower end of the two first sidewalls 4221 and at the lower end of the second sidewall 4222 located between the two first sidewalls 4221.

[0128] Specifically, the length of the second wedge surface 72 arranged on the second sidewall 4222 is less than the length of the second wedge surface 72 arranged on the first sidewall 4221. The second wedge surface 72 arranged on the second sidewall 4222 only provides one end of the sliding trajectory, while the second wedge surface 72 arranged on the first sidewall 4221 provides the entire sliding trajectory. Figure 9 The second wedge surface 72 arranged on the first side wall 4221 is adapted to abut against the first wedge surface 71 arranged on the first side part 62 and the second side part 63, and the second wedge surface 72 arranged on the second side wall 4222 is adapted to abut against the first wedge surface 71 arranged on the main body part 61.

[0129] In some examples, only one set of second wedge surfaces 72 as described above may be arranged on the second transmission part 422.

[0130] In other examples, such as the appendix Figure 10 and Figure 11 As shown, two sets of second wedge surfaces 72 as described above can be arranged on the second transmission part 422, and the two sets of second wedge surfaces 721 are arranged symmetrically. That is, two second wedge surfaces 72 are arranged simultaneously on the first sidewall 4221, and the two second wedge surfaces 72 are arranged symmetrically. The lower end of one second wedge surface 72 extends to the middle position of the lower end of the first sidewall 4221, and the lower end of the other second wedge surface 72 extends to the middle position of the lower end of the first sidewall 4221. This facilitates the fabrication of the movable cover 4 using an integral molding process.

[0131] In the case where two sets of second wedge surfaces 72 are arranged on the second transmission part 422, only one set of second wedge surfaces 72 can interact with the transmission member 6 (the transmission member 6 is arranged as one), or each set of second wedge surfaces 72 can be adapted to work with one transmission member 6 (the transmission member 6 is arranged symmetrically with two).

[0132] The above-mentioned structural design of the second transmission part 422 not only simplifies the structure of the movable cover 4, but also simplifies the manufacturing process of the movable cover 4. The movable cover 4 can be manufactured using a simple one-piece molding process.

[0133] Of course, it is not excluded that the first transmission part 412 may be arranged only at a specific position on the outer side of the second cover part 421, rather than being arranged in a circle around the second cover part 421.

[0134] In the embodiments of the present invention, as shown in the appendix Figure 3 Or attach Figure 12 As shown, the switch 5 is located on one side of the plug assembly 3, and elastic support 9 is provided around the other sides of the plug assembly 3. The elastic support 90 is used to center the movable cover 4, prevent the movable cover 4 from tilting, and will not affect the pressing activity of the movable cover 4.

[0135] For example, the elastic support 90 includes, but is not limited to: a heart-shaped groove pressing structure, a ratchet pressing structure or an elephant trunk buckle pressing structure, a compression spring, etc.

[0136] In some examples, such as the attached Figure 3 As shown, in the case where the transmission component 6 is not provided in the socket, the elastic support component 90 can adopt the same pressing structure as the switch component 5, or an additional switch component identical to the switch component 5 can be used as the elastic support component 90 (see [reference]). Figure 3 However, this additional switch is not electrically connected to the socket assembly 3; it only serves to support the movable cover 4 and assist in plug insertion and removal.

[0137] In some examples, such as the attached Figure 12 As shown, in the case where the transmission member 6 is provided in the socket, the elastic support member 90 can include: a pressing structure identical to that of the switch member 5 and a transmission structure identical to that of the transmission member 6; or, the elastic support member 90 can include: an additional switch member identical to that of the switch member 5 and an additional transmission member identical to that of the transmission member 6 (see...). Figure 12 However, this additional switch is not electrically connected to the socket assembly 3, but only works in conjunction with the additional transmission component to support the movable cover 4 and assist in plug insertion and removal.

[0138] See Figure 6When the socket is an extension cord socket, the switch 5 and the transmission 6 are located on the side of the socket assembly 3 closer to the extension cord plug to facilitate wiring.

[0139] Furthermore, in order to further ensure that the movable cover 4 is centered in the through hole 10 and moves only in the vertical direction to avoid tilting or offset, the socket may also include a positioning mechanism configured to make the movable cover 4 move only in the vertical direction and avoid movement in other directions.

[0140] For example, as shown in the appendix Figure 5 and attached Figure 10 As shown, the positioning mechanism can be a bushing structure. For example, one of the movable cover 4 and the base 2 is arranged with a positioning block 91 extending in the vertical direction, and the other is arranged with a positioning sleeve 92 extending in the vertical direction. The positioning block 91 is fitted inside the positioning sleeve 92, and the two are fitted with a clearance, so that the movable cover 4 can only move in the vertical direction relative to the base 2, and cannot move in other directions.

[0141] The positioning block 91 and the positioning sleeve 92 are structurally compatible. For example, if the positioning block 91 is a cylindrical shaft, then the inner cavity of the positioning sleeve 92 is also circular. Alternatively, if the positioning block 91 is a trapezoidal block with an inclined surface, then the inner cavity of the positioning sleeve 92 is also trapezoidal.

[0142] In this embodiment of the invention, the faceplate 1, base 2, movable cover 4, switch 5, and transmission component 6 can each be manufactured using an integral molding process, making them an integrally molded structure. It should be noted that, due to the special nature of the integral molding process, when manufacturing using a mold, the faceplate 1, base 2, movable cover 4, switch 5, and transmission component 6 may all have some groove structures caused by the molding process; this does not affect the basic functions of the aforementioned components.

[0143] In summary, the socket provided in this embodiment of the invention, through the cooperation of the movable cover 4 and the switch 5, allows the socket to draw power as needed and disconnect power when the plug is unplugged, improving the operational safety of the socket. Furthermore, the cooperation of the movable cover 4 and the switch 5 also assists in plugging and unplugging the plug. A single press of the button with one hand is enough to turn on the socket, and two presses will disconnect the socket from the power supply. The plug can be unplugged with one hand, making plugging and unplugging smoother and less strenuous, which is both ergonomic and enhances safety.

[0144] Furthermore, by arranging the socket assembly 3 and the switch 5 sequentially along a direction parallel to the face cover 1, the switch 5 no longer occupies the space between the socket assembly 3 and the face cover 1, but occupies the space on one or both sides of the socket assembly 3. For the socket cavity, the part of the socket cavity located on one side of the socket assembly 3 has more unused space. This makes full use of the unused space of the socket cavity, which is conducive to the development of the socket's thinness and lightness, and avoids the limitation on the size of the switch 5, which is conducive to the working stability of the switch 5.

[0145] In addition, placing the switch 5 on one side of the socket assembly 3 may result in an increase in the length or width of the socket. For the socket, the increase in length or width is relatively small compared to the increase in thickness, so the increase in the volume of the socket cavity is limited and more acceptable to users.

[0146] The movable cover 4 has a socket 40, so that the movable cover 4 covers at least the top of the socket, giving the movable cover 4 a large area and a large contact area between the plug and the movable cover 4. Compared with the point-to-surface contact between the elastic button and the plug in the related art, the embodiment of the present invention makes the plug and the movable cover 4 make surface-to-surface contact, which gives the plug the advantages of strong stability and high reliability when pressing down on the movable cover 4 and when the movable cover 4 pushes up on the plug.

[0147] The switch 5 is locked and unlocked by pressing the movable cover 4. In this way, the movable cover 4 serves as both a plug pushing mechanism and a switch unlocking mechanism. The switch 5 does not need to be equipped with an additional unlocking mechanism, which helps to reduce the number of internal parts of the socket and simplify the structure of the socket.

[0148] In summary, the socket provided by the embodiments of the present invention, in addition to the advantages of high safety and easy plugging and unplugging, also has the advantages of simple structure, strong working stability, high reliability, and thinness.

[0149] In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0150] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
