It has the advantages of simple structure, stable and reliable performance, and convenient wiring. However, the socket assembly in this technical solution is only set between the top cover and the base. The top cover and the base do not have a structure to limit and fix the socket assembly. During use, plugging and unplugging the plug will cause the socket assembly to shake inside, which will affect the stability of the electrical connection. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a socket. The socket of this utility model has a structure for limiting and fixing the plug assembly, which prevents the plug assembly from shaking inside the socket when plugging or unplugging the plug, thus ensuring a stable electrical connection.
[0005] The technical solution adopted by this utility model is as follows: a socket, including a base, a socket assembly and a top cover, wherein the base is provided with a mounting cavity, the top cover is fastened to the mounting cavity, the socket assembly is disposed inside the mounting cavity, and the inner wall of the top cover is provided with an abutment portion. When the top cover is fastened to the mounting cavity, the abutment portion abuts against the top surface of the socket assembly, and the bottom wall of the mounting cavity abuts against the bottom surface of the socket assembly.
[0006] The socket assembly includes a live wire socket, a neutral wire socket, and a ground wire socket. The mounting cavity has a live wire cavity, a neutral wire cavity, and a ground wire cavity for the live wire socket, the neutral wire socket, and the ground wire socket to be embedded, respectively. The ground wire cavity is located between the live wire cavity and the neutral wire cavity.
[0007] The two side walls of the grounding cavity are respectively provided with a first limiting piece and a second limiting piece. The middle part of the live wire socket is embedded between the first limiting piece and the inner wall of the mounting cavity, and the middle part of the neutral wire socket is embedded between the second limiting piece and the inner wall of the mounting cavity.
[0008] The socket assembly further includes a live wire terminal, a neutral wire terminal, and a ground wire terminal. The live wire socket is electrically connected to the live wire terminal via a first connecting piece, the neutral wire socket is electrically connected to the neutral wire terminal via a second connecting piece, and the ground wire socket is electrically connected to the ground wire terminal via a third connecting piece. A first wiring port adapted to the live wire terminal is provided on one side of the mounting cavity, and a second wiring port adapted to the neutral wire terminal is provided on the other side of the mounting cavity. A third wiring port communicating with the ground wire cavity is also provided in the middle of the mounting cavity. The first wiring port, the second wiring port, and the third wiring port are all separated from each other.
[0009] The abutting part includes at least two first abutting pieces, which abut against the middle of the live wire socket and the middle of the neutral wire socket, respectively.
[0010] The abutting part includes at least two second abutting pieces, and the grounding socket has at least one extension piece protruding on each side, with the two second abutting pieces abutting against one extension piece respectively.

The rotating shaft has a protrusion on its side and a groove that matches the protrusion on its side. The waterproof cover has an open state and a closed state by rotating relative to the panel. When the waterproof cover is in the open state, the protrusion slides into the groove to form a snap-fit. When the waterproof cover is in the closed state, the protrusion slides out of the groove.
[0013] One end face of the base is a flat surface for mounting on a wall, and the mounting cavity protrusion is located on the other end face of the base away from the flat surface.
[0014] The beneficial effects of this utility model are as follows: The socket of this utility model has a structure for limiting and fixing the socket assembly, that is, the abutment part is set on the inner wall of the upper cover. When the upper cover is fastened and installed on the mounting cavity, the socket assembly inside the mounting cavity is abutted between the abutment part and the inner wall of the mounting cavity, forming a two-way limiting structure. This prevents the socket assembly from shaking inside the socket when plugging or unplugging the plug, ensuring a stable and reliable electrical connection, preventing the plug from being difficult to insert into the socket or generating an electric arc due to poor contact, and also avoiding metal fatigue damage caused by the shaking of the socket assembly, thus extending its service life. The limiting function of the socket assembly can be achieved simply by optimizing the structure of the upper cover, resulting in a simplified structure and lower production cost.

It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model.

[0026] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0027] like Figures 1 to 7 As shown, this is an embodiment of the present invention. The socket includes a base 1, a socket assembly, and a top cover 2. The base 1 has a mounting cavity 3. The top cover 2 is fastened to the mounting cavity 3. The socket assembly is disposed inside the mounting cavity 3. The inner wall of the top cover 2 has an abutment portion. When the top cover 2 is fastened to the mounting cavity 3, the abutment portion abuts against the top surface of the socket assembly, and the bottom wall of the mounting cavity 3 abuts against the bottom surface of the socket assembly.
[0028] The beneficial effects of this design are as follows: The socket of this utility model has a structure for limiting and fixing the socket assembly, namely, the abutment part set on the inner wall of the upper cover. When the upper cover is fastened and installed on the mounting cavity, the socket assembly inside the mounting cavity is abutted between the abutment part and the inner wall of the mounting cavity, forming a two-way limiting structure. This prevents the socket assembly from shaking inside the socket when plugging or unplugging the plug, ensuring a stable and reliable electrical connection, preventing the plug from being difficult to insert into the socket or generating an electric arc due to poor contact, and also avoiding metal fatigue damage caused by the shaking of the socket assembly, thus extending its service life. The limiting function of the socket assembly can be achieved simply by optimizing the structure of the upper cover, resulting in a simplified structure and lower production costs.
[0029] Further, the socket assembly includes a live wire socket 4, a neutral wire socket 5, and a ground wire socket 6. The mounting cavity 3 is provided with a live wire cavity 7, a neutral wire cavity 8, and a ground wire cavity 9 for embedding the live wire socket 4, the neutral wire socket 5, and the ground wire socket 6, respectively. The ground wire cavity 9 is located between the live wire cavity 7 and the neutral wire cavity 8.
[0030] The beneficial effects of this design are as follows: the live wire socket, neutral wire socket, and ground wire socket each have their own corresponding chambers for embedding, and the ground wire socket is installed between the live wire socket and the neutral wire socket, forming a symmetrical layout structure of high voltage-ground wire-high voltage, which reduces electromagnetic interference between the live wire and the neutral wire, avoids short circuits, improves the safety performance of the circuit, and the chamber design forms multiple cavity walls, increasing the structural strength of the mounting cavity and the support for the top cover.
[0031] Further configuration: the two side walls of the ground wire cavity 9 are respectively provided with a first limiting piece 10 and a second limiting piece 11 protruding; the middle part of the live wire socket 4 is embedded between the first limiting piece 10 and the inner wall of the mounting cavity 3; and the middle part of the neutral wire socket 5 is embedded between the second limiting piece 11 and the inner wall of the mounting cavity 3.
[0032] The beneficial effects of this design are as follows: the first and second limiting plates respectively cooperate with the inner wall of the mounting cavity to limit and clamp the middle side wall of the live wire socket and the middle side wall of the neutral wire socket, supplementing the lateral limiting structure to prevent the live wire socket and the neutral wire socket from shifting laterally. Combined with the vertical limiting of the abutment part, a multi-dimensional limiting effect is formed to ensure the stable installation of the socket assembly. The limiting plates and the inner wall of the mounting cavity also form a guide groove structure, which facilitates the quick installation of the live wire socket and the neutral wire socket into the correct position.
[0033] Further, the socket assembly includes a live wire terminal 12, a neutral wire terminal 13, and a ground wire terminal 14. The live wire socket 4 is electrically connected to the live wire terminal 12 via a first connecting piece 15. The neutral wire socket 5 is electrically connected to the neutral wire terminal 13 via a second connecting piece 16. The ground wire socket 6 is electrically connected to the ground wire terminal 14 via a third connecting piece 17. A first wiring port 18 adapted to the live wire terminal 12 is provided on one side of the mounting cavity 3. A second wiring port 19 adapted to the neutral wire terminal 13 is provided on the other side of the mounting cavity 3. A third wiring port 20 communicating with the ground wire cavity 9 is also provided in the middle of the mounting cavity 3. The first wiring port 18, the second wiring port 19, and the third wiring port 20 are all separated from each other.
[0034] The beneficial effects of this design are as follows: the first, second, and third terminals corresponding to the live wire socket, neutral wire socket, and ground wire socket are also independently and separately designed, realizing the physical separation and directional wiring function of the high-voltage line, eliminating the risk of misconnection or cross-short circuit. The layout of the terminals and the layout of the socket cavity are synergistically enhanced, resulting in a more reasonable layout. A multi-level electromagnetic shielding zone is formed inside the socket, reducing the intensity of AC magnetic field radiation. The two side walls of the third terminal are formed by multiple bends of the side walls of the mounting cavity, forming an independent wiring channel for the third terminal, which is a straight-through structure. This allows the ground wire terminal to obtain the shortest conductive path, prioritizes the establishment of equipment grounding protection circuit, and improves the response speed of leakage protection.
[0035] In a further configuration, the abutting portion includes at least two first abutting pieces 21, which abut against the middle portion of the live wire socket 4 and the middle portion of the neutral wire socket 5, respectively.
[0036] The beneficial effects of this design are as follows: using two independent first abutting pieces to abut the middle of the live wire socket and the neutral wire socket respectively avoids stress coupling interference, ensures independent force distribution, and guarantees good electrical connection stability when both plugs are inserted into the socket at the same time. It also ensures the secure installation of the socket and disperses the lateral stress generated when plugging and unplugging the plug to the strongest rigid area in the middle of the socket, avoiding deformation or breakage at the end of the socket due to local stress concentration. This significantly improves the bending resistance and long-term reliability of the socket.
[0037] In a further configuration, the abutting portion includes at least two second abutting pieces 22, and the grounding socket 6 has at least one extension piece 23 protruding on each side, with the two second abutting pieces 22 abutting against one extension piece 23 respectively.
[0038] The beneficial effects of this design are as follows: the second abutting piece separately abuts and limits the grounding socket. The copper sheet of the grounding socket is small in shape. By integrally bending and setting extension pieces on both sides of the grounding socket for the second abutting piece to abut. When the top cover is fastened, the second abutting piece can also automatically correct the position of the grounding socket, ensuring that the grounding end of the three-prong plug is smoothly inserted into the grounding socket.
[0039] In a further configuration, the abutting portion includes at least two third abutting pieces 24, which abut against the first connecting piece 15 and the second connecting piece 16 respectively.
[0040] The beneficial effects of this design are as follows: it also limits and abuts the first connecting piece of the live wire socket and the second connecting piece of the neutral wire socket, ensuring a stable electrical connection between the connecting piece and the terminal piece, and preventing misalignment during wire crimping. The abutting parts are integrally formed with the top cover, achieving multi-point limiting function without increasing the number of parts, maintaining the overall thinness of the socket, and providing evenly distributed abutting force.
[0041] Further configuration includes a panel 25 and a waterproof cover 26 disposed on the panel 25. The panel 25 is fastened to the end face of the base 1 near the mounting cavity 3. The waterproof cover 26 is rotatably connected to the panel 25 via a rotating assembly. The rotating assembly includes a rotating shaft 27 disposed on the panel 25 and a rotating hole 28 disposed on the waterproof cover 26. A protrusion 29 protrudes from the side of the rotating shaft 27, and a groove 30 adapted to the protrusion 29 is recessed from the side of the rotating hole 28. The waterproof cover 26 has an open state and a closed state by rotating relative to the panel 25. When the waterproof cover 26 is in the open state, the protrusion 29 slides into the groove 30 to form a snap-fit engagement. When the waterproof cover 26 is in the closed state, the protrusion 29 slides out of the groove 30.
[0042] The beneficial effects of this design are as follows: the waterproof cover protects the socket from water ingress that could cause a short circuit; the waterproof cover uses a stepped rotating structure with a combination of protrusions and grooves, requiring greater force to open or close, thus preventing it from being opened or closed unnecessarily.
[0043] Further configuration: one end face of the base 1 is a plane 31 for mounting on a wall, and the mounting cavity 3 protrudes from the other end face of the base 1 away from the plane 31.
[0044] The advantages of this setup are as follows: the socket is installed using a surface-mount method, with the socket assembly mounted on the base. This is more convenient than mounting it on a panel. The base and socket assembly are mounted on the wall, and the wires can be connected first. The installation can be completed simply by snapping the panel onto the base. The wiring is also cleaner, avoiding wire tangling when snapping the panel, and it is also easier to match different panels.
[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
