Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a socket. Background Technology

[0002] In related technologies, sockets are typically equipped with safety shutters. These safety shutters keep the socket closed when no plug is inserted. The main function of these safety shutters is to prevent foreign objects from being accidentally inserted into the socket, thus avoiding damage to equipment or safety accidents. They also effectively prevent electric shock accidents caused by accidental contact with the socket, improving the safety of socket use.

[0003] To meet diverse electricity needs, current sockets typically feature various types of socket structures, such as two-phase sockets, three-phase sockets, and USB ports, to accommodate different types of electrical devices. However, in related technologies, each type of socket (e.g., two-phase, three-phase, and USB ports) is individually equipped with a corresponding protective shutter assembly. However, sockets with protective shutter assemblies in these technologies have complex assembly processes, resulting in low assembly efficiency. Utility Model Content

[0004] This utility model discloses a socket to solve the problem of low assembly efficiency caused by the complex assembly process of sockets in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] This application discloses a socket, which includes a housing, a protective door mechanism, and a power supply module. The protective door mechanism and the power supply module are both disposed inside the housing. The housing has a plurality of first socket groups, and the power supply module is disposed on the side of the protective door mechanism opposite to the first socket groups.

[0007] The protective door mechanism includes a first base and a plurality of door components movably disposed on the first base. The first base has a plurality of second socket groups, each of which corresponds to a plurality of first socket groups. The plurality of door components also correspond to a plurality of second socket groups.

[0008] The door assembly is configured to move to a position that avoids the second socket group when the plug is inserted into the socket, so that the plug can be electrically connected to the power supply module, and to move to a position that blocks the second socket group when the plug is separated from the socket.

[0009] The technical solution adopted in this utility model can achieve the following technical effects:

[0010] The socket disclosed in this application has a protective door mechanism, which is configured to include a first base and multiple door components. When a plug is inserted into the socket, the door components move to a position that avoids the second socket group. At this time, the door components are in an open state, and the plug can be electrically connected to the power supply module. When the plug is separated from the socket, the door components move to a position that blocks the second socket group, thereby closing the door components and preventing foreign objects from entering the sockets or accidental electric shock. By integrating multiple door components onto the first base to form a modular structure, the protective door mechanism can be directly installed into the housing during socket assembly, thus simplifying the socket assembly process and improving assembly efficiency.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figures 1 to 20 This utility model discloses a socket, which includes a housing 100, a protective door mechanism 200, and a power supply module 300.

[0042] The housing 100 can provide a mounting base for other components of the socket. The housing 100 may have an inner cavity, and the protective door mechanism 200 and the power supply module 300 are both located inside the housing 100, that is, the protective door mechanism 200 and the power supply module 300 are both located in the inner cavity.

[0043] The housing 100 has multiple first insertion hole groups, please refer to... Figure 1The multiple first socket groups may include a first two-phase socket group 111, a first three-phase socket group 112, a first USB socket group 113, etc. The housing 100 may include a front housing 110 and a rear housing 120. The multiple first socket groups may be formed in the front housing 110. The front housing 110 and the rear housing 120 can be connected in a detachable manner. The rear housing 120 can be used as a component for socket installation on a mounting base (e.g., a wall).

[0044] The power supply module 300 is located on the side of the protective door mechanism 200 opposite to the first socket group.

[0045] The protective door mechanism 200 includes a first base 210 and multiple door components 220 movably disposed on the first base 210. The first base 210 has multiple second socket groups, each corresponding to a set of first socket groups, and the multiple door components 220 correspond one-to-one with each set of second socket groups. The door components 220 can be disposed between the first base 210 and the power supply module 300.

[0046] Please refer to Figure 2 Multiple second socket groups may include a second two-phase socket group 211a, a second three-phase socket group 211b, a second USB socket group 211c, etc.

[0047] In the insertion direction of the plug into the socket, multiple second socket groups correspond one-to-one with multiple first socket groups. For example, the first two-phase socket group 111 is opposite to the second two-phase socket group 211a, the first three-phase socket group 112 is opposite to the second three-phase socket group 211b, and the first USB socket group 113 is opposite to the second USB socket group 211c.

[0048] The door assembly 220 is used to move to a position that avoids the second socket group when the plug is inserted into the socket, so that the plug can be electrically connected to the power supply module 300, and the door assembly 220 is used to move to a position that blocks the second socket group when the plug is separated from the socket.

[0049] Specifically, when the plug is inserted into the socket through the first socket group and the second socket group in sequence, the corresponding door assembly 220 moves to a position to avoid the second socket group so that the plug can be electrically connected to the power supply module 300; when the plug is separated from the socket, the corresponding door assembly 220 moves to a position to block the second socket group.

[0050] The socket disclosed in this application embodiment features a protective door mechanism 200, which includes a first base 210 and multiple door components 220. When a plug is inserted into the socket, the door components 220 move to a position that avoids the second socket group, at which point they are in an open state, allowing the plug to be electrically connected to the power supply module 300. When the plug is separated from the socket, the door components 220 move to a position that blocks the second socket group, thus closing the socket and preventing foreign objects from entering the sockets or accidental electric shock. By integrating multiple door components 220 onto the first base 210 to form a modular structure, the protective door mechanism 200 can be directly installed into the housing 100 during socket assembly, simplifying the assembly process and improving assembly efficiency.

[0051] Optionally, the door assembly 220 may include a protective door panel that can be moved between a position that avoids the second socket group and a position that blocks the second socket group by manual operation by the user (the specific operation process can be referred to below).

[0052] To enable the door panel to automatically block the second socket group when the plug and socket are disconnected, the door assembly 220 may optionally include a protective door panel and a resilient mechanism. The protective door panel is movably mounted on the first base 210. Specifically, the protective door panel is slidably mounted on the first base 210, and the resilient mechanism is connected between the first base 210 and the protective door panel. When the plug is inserted into the socket, the protective door panel moves to a position that avoids the second socket group, allowing the plug to be electrically connected to the power supply module 300, and the resilient mechanism stores elastic force. When the plug and socket are disconnected, under the action of the elastic force of the resilient mechanism, the resilient mechanism drives the protective door panel to move to a position that blocks the second socket group, thereby enabling the protective door panel to automatically block the second socket group.

[0053] Specifically, the multiple door components 220 may include two-phase door components, three-phase door components, SUB door components, etc. Please refer to [reference needed]. Figure 2The two-phase door assembly may include a two-phase protection door panel 221a and a first elastic element 222a; the three-phase door assembly may include a three-phase protection door panel 221b and a second elastic element 222b; and the SUB door assembly may include a USB protection door panel 221c and a third elastic element 222c. The shapes of the two-phase protection door panel 221a, three-phase protection door panel 221b, and USB protection door panel 221c in the figures are merely illustrative. This application embodiment does not impose specific limitations on the shapes of the two-phase protection door panel 221a, three-phase protection door panel 221b, and USB protection door panel 221c. The first elastic element 222a and the second elastic element 222b may be circular springs, and the third elastic element 222c may be a V-shaped elastic element. Of course, the above are merely examples of the first elastic element 222a, the second elastic element 222b, and the third elastic element 222c, and are not intended as limitations. The first elastic element 222a, the second elastic element 222b, and the third elastic element 222c may also adopt other elastic structures, and this application embodiment does not impose any limitations on this.

[0054] To make the movement of the protective door panel between the position avoiding the second socket group and the position blocking the second socket group more stable, the first base 210 may optionally have multiple guide portions, which may correspond one-to-one with multiple door assemblies 220. The protective door panel may have guide mating portions, which may guide and engage with corresponding guide portions in an insertion direction perpendicular to the plug insertion socket, so as to move the protective door panel between the position avoiding the second socket group and the position blocking the second socket group.

[0055] The socket disclosed in this application provides multiple guide portions on the first base 210 corresponding to multiple door assemblies 220, and provides guide mating portions on the protection door panel, so that the protection door panel is more stable when moving between the position of avoiding the second socket group and the position of blocking the second socket group under the guidance and cooperation of the guide mating portions and the corresponding guide portions.

[0056] In one optional embodiment, the first base 210 may be provided with an annular barrier 213 at the position corresponding to each protective door panel. The protective door panel may be located within the annular barrier 213 and may move within the annular barrier 213 to enable the protective door panel to move between the position of avoiding the second socket group and the position of blocking the second socket group.

[0057] Please refer to Figure 4 The ring-shaped fence 213 can be a closed ring structure or a ring structure with an opening. The ring-shaped fence 213 can be polygonal, circular, or other shapes. This application embodiment does not impose specific limitations on the structure and shape of the ring-shaped fence 213.

[0058] The socket disclosed in this application embodiment provides annular barriers 213 at positions corresponding to each protective door panel on the first base 210, so that the protective door panels can be placed within the annular barriers 213 at the corresponding positions. This can play an auxiliary positioning role for the protective door panels during the assembly of the protective door mechanism 200, thereby improving the assembly efficiency of the protective door mechanism 200 and thus improving the assembly efficiency of the socket.

[0059] Alternatively, please refer to Figure 4 , Figure 12 and Figure 13 In the direction of movement perpendicular to the protective door panel, the annular enclosure 213 may have two opposing guide sidewalls 213a, and the guide portion may include the two opposing guide sidewalls 213a. The guide mating portion may include a guide end 2211 of the protective door panel opposite to the two guide sidewalls 213a, and the guide end 2211 may guide and engage with the guide sidewalls 213a in the direction of movement of the protective door panel. The guide sidewalls 213a may be provided with a first limiting protrusion 213a1, which may limit and engage with the protective door panel at the top of the annular enclosure 213. The protective door panel may be confined between the first seat 210 and the first limiting protrusion 213a1.

[0060] The socket disclosed in this application uses two side walls of the annular enclosure 213 in the direction perpendicular to the movement of the protective door panel as guide side walls 213a, and the ends of the protective door panel opposite to the two guide side walls 213a as guide ends 2211. This allows the guide ends 2211 and the guide side walls 213a to guide and cooperate in the direction of movement of the protective door panel, thereby making full use of the structure of the annular enclosure 213 and the protective door panel, which is beneficial to optimizing the structure of the socket.

[0061] Optionally, in the direction of movement of the protective door panel, the protective door panel may have a limiting end 2212, and the annular barrier 213 may have a limiting sidewall 213b opposite to the limiting end 2212. When the elastic mechanism drives the protective door panel to move to the position of blocking the second set of insertion holes, the limiting end 2212 can be positioned and engaged with the limiting sidewall 213b, so that the protective door panel can be accurately stopped at the position of blocking the second set of insertion holes.

[0062] An alternative embodiment is provided below. Figure 4 and Figure 6 At least some of the multiple guide sections may include guide posts 212, the extension direction of which is parallel to the movement direction of the protective door panel. The protective door panel that mates with the guide posts 212 may have a groove 2215, and the guide mating part may include the groove 2215, through which the guide posts 212 can be slidably fitted onto the guide posts 212.

[0063] In another implementation, please refer to Figure 4 and Figure 10 At least some of the multiple guide portions may include two guide protrusions 214 that are opposite to each other and spaced apart, and a first buckle 215 located on the top of the guide protrusions 214. The protective door panel can be fastened between the two guide protrusions 214 by the first buckle 215, and the protective door panel and the guide protrusions 214 can be guided and engaged in the direction of movement of the protective door panel.

[0064] Of course, the guide part and the guide mating part can also be other structures, such as a guide rail slider structure, etc. The embodiments of this application do not impose specific restrictions on the structure of the guide part and the guide mating part.

[0065] Please refer to Figure 5 , Figure 7 , Figure 8 and Figure 9 There are many ways to achieve the protection door panel avoiding the second socket group. Optionally, the protection door panel can have a guide slope 2213. When the plug is inserted into the socket, the plug (specifically the conductive prong 500 of the plug) can cooperate with the guide slope 2213 to move the protection door panel to a position that avoids the second socket group.

[0066] The socket disclosed in this application provides a guide slope 2213 on the protective door panel, so that when the plug is inserted into the socket, the plug can slide and engage with the guide slope 2213 to drive the protective door panel to move to a position that avoids the second socket group, thereby realizing that the protective door panel is automatically opened when the plug is inserted into the socket.

[0067] In another implementation, please refer to Figure 11 and Figure 12 The protective door panel may have a manual toggle part 2214, which can be used by the user to drive the protective door panel to a position to avoid the second socket group.

[0068] The socket disclosed in this application embodiment has a manual toggle part 2214 on the protective door panel, which allows the user to drive the protective door panel to move to a position that avoids the second socket group. This improves the user's operability and allows the user to promptly detect whether the protective door panel is functioning properly during operation. This avoids the user being unaware of the protective door panel's malfunction, which could lead to foreign objects entering the socket or electric shock.

[0069] Optionally, the power supply module 300 may include a second base 310, a conductive clip assembly 320, and a circuit board 330. The second base 310 may serve as the mounting base for other components of the power supply module 300. Both the circuit board 330 and the conductive clip assembly 320 may be located on the second base 310, and the conductive clip assembly 320 is electrically connected to the circuit board 330. There may be multiple conductive clip assemblies 320, and each set of conductive clip assemblies 320 may correspond one-to-one with a set of door assemblies 220. The conductive clip assembly 320 is used to hold the conductive prongs 500 of the plug after the plug is inserted into the socket, thereby achieving electrical connection between the plug and the power supply module 300.

[0070] The socket disclosed in this application configuration has a power supply module 300 structure including a second base 310, a conductive clip group 320 and a circuit board 330, such that the conductive clip group 320 and the circuit board 330 are disposed on the second base 310 to form a modular structure, which is beneficial for socket assembly.

[0071] The conductive clip assembly 320 can be fixed to the second base 310 by a screw structure. In another embodiment, the conductive clip assembly 320 can be limited to the second base 310 by the limiting rib 311 on the second base 310, so that the conductive clip assembly 320 does not need to be fixed by screws, thereby facilitating the installation of the conductive clip assembly 320.

[0072] Furthermore, the power supply module 300 may also include a pressure plate 340, which may have an embedding groove 341 corresponding to the multiple conductive clip groups 320. The pressure plate 340 may be connected to the second base 310, and a portion of the conductive clip group 320 may be embedded in the embedding groove 341. The pressure plate 340 may press the conductive clip group 320 onto the second base 310.

[0073] The socket disclosed in this application embodiment has a pressure plate 340, which allows a portion of the conductive clip group 320 to be embedded in the embedding groove 341, and the pressure plate 340 presses the conductive clip group 320 onto the second base 310, thereby making the installation of the conductive clip group 320 more stable.

[0074] The pressure plate 340 and the second base 310, as well as the circuit board 330 and the second base 310, can be connected by screws. To facilitate the assembly of the pressure plate 340, the circuit board 330 and the second base 310, the pressure plate 340 and the second base 310 can optionally be snapped together by the second snap 350, and the circuit board 330 can be snapped together by the third snap 360. This snap-fit ​​connection facilitates the assembly of the pressure plate 340, the circuit board 330 and the second base 310.

[0075] Optionally, the multiple conductive clip groups 320 can be a separate structure, and the multiple conductive clip groups 320 can be installed individually on the second base 310.

[0076] In another embodiment, the neutral wire conductive clip 321 in the plurality of conductive clip groups 320 can be an integral structure, and the live wire conductive clip 322 in the plurality of conductive clip groups 320 can be an integral structure, which helps to reduce the number of components in the socket and also facilitates the installation of the conductive clip group 320 and the second base 310.

[0077] The multiple conductive clip groups 320 may include two-phase conductive clip groups 320, three-phase conductive clip groups 320, etc. When the multiple conductive clip groups 320 include three-phase conductive clip groups 320, the three-phase conductive clip group 320 may also include a grounding conductive clip 323.

[0078] Optionally, the socket may also include a switch 400, part of which may be located inside the housing 100 and the other part may extend outside the housing 100. The user can turn the circuit board on and off by operating the switch 400.

[0079] Optionally, the circuit board 330 may include a control circuit board 331 and a power supply circuit board 332. The control circuit board 331 may be equipped with a ZigBee communication module, a switch button, an LED indicator, a USB output interface, etc., and the power supply circuit board 332 may be equipped with a relay, a metering chip, etc.

[0080] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0081] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
