Description

TECHNICAL AREA

[0001] The application concerns the field of electrical appliance technology, in particular a mains socket and a double-sided socket module thereof. STATE OF THE ART

[0002] Sockets, as a common electrical device, have become widespread in everyday life and in offices. To increase the power supply options of the socket, existing technology typically arranges multiple power supply holes in a matrix on a side panel. For example, patent "CN208522151U" relates to a double-sided socket, meaning the power supply holes are symmetrically arranged on opposite end faces of the socket. However, in the double-sided sockets of these existing technologies, the socket housings are generally used as carriers, with power supply holes arranged on both sides. The socket plates are attached to the housings, and the metal conductor strips are divided inside the housings. This design has the following problems: 1. Complex structure: Existing double-sided sockets require a complex housing structure to attach socket plates and guide strips, which complicates manufacturing and assembly. 2. Greater thickness: To avoid the risk of interference when drawing power through the double-sided sockets, the thickness of existing double-sided sockets is usually greater, which does not contribute to space savings. 3. Inconvenient installation: Positioning and attaching the guide rails in the existing technology is complex, leading to inefficient installation.

[0003] Therefore, a double-sided socket module with a simple structure, smaller thickness and convenient installation is urgently needed to solve the problems mentioned above. CONTENT OF THE PRESENT INVENTION

[0004] To solve the problems mentioned above, the first task of the application is to provide a double-sided socket module, which on the one hand allows two rear groups of socket units to be permanently connected without the aid of a socket housing, and on the other hand simplifies the installation structure.

[0005] To achieve the aforementioned purposes, the application adopts the following technical solutions: Double-sided socket module, characterized in that it comprises two groups of socket units arranged opposite each other and fixedly connected, as well as L-conductors and N-conductors arranged between the two groups of socket units, wherein both groups of socket units are consistently equipped with at least one current extraction position; wherein, when the two groups of socket units are fixedly connected from the rear, a conductive connection exists between contacts within the socket units and the L-conductors and N-conductors.

[0006] By adopting the above technical solution, in which the double-sided socket module comprises two groups of socket units arranged opposite each other and permanently connected, as well as L- and N-conductors arranged between the two groups of socket units, wherein the two groups of socket units are permanently connected at the rear, and where this rear connection creates a conductive connection between contacts within the socket units and the L- and N-conductors, stable current transmission is ensured. In this way, two groups of socket units can be permanently attached without the aid of a socket housing, and the installation structure can be simplified.

[0007] Preferably, the two groups of socket units are arranged opposite each other and can be clamped together and snap together. By arranging the two groups of socket units opposite each other and clamping together and snapping together, this technical solution solves the problem of a stable connection when two groups of socket units are arranged opposite each other in a double-sided socket module. In particular, when two groups of socket units are arranged opposite each other, a stable connection is achieved through clamping and snapping together, thus avoiding the problems of increased thickness and complex structure of the conventional double-sided socket module caused by the mounting of the socket plate to the socket housing. This design not only simplifies the structure but also improves the stability and reliability of the socket module.

[0008] Preferably, two groups of bushing units are constructed as molded parts with the same structure, each bushing unit having a clamping slot and a clamping block on its rear side. A clamping hook is provided within the clamping slot, and the clamping block has a clamping opening. When the two groups of bushing units are rigidly connected from the rear, the clamping block of one bushing unit projects into the clamping slot of the other bushing unit, and the clamping hook is engaged in the clamping opening of the clamping block within the clamping slot. By constructing two groups of bushing units as molded parts with the same structure, this solution simplifies the manufacturing process and improves ease of assembly.The fact that each socket unit on the reverse side is equipped with a clamping slot and a clamping block, with a clamping hook inside the clamping slot and a clamping opening in the clamping block, allows for a quick and stable connection when the two groups of socket units are securely connected from the back. This design not only reduces the number of installation steps but also improves the overall structural strength and stability of the socket module, effectively solving the problems of the complex structure and awkward installation of conventional double-sided socket modules.

[0009] Preferably, a positioning element for positioning the metal guide strips is provided on the rear of the socket unit. During installation, the L- and N-guide strips are positioned by positioning elements on the rear of one socket unit, and when the other socket unit is permanently connected, the L- and N-guide strips are clamped between the two groups of socket units. By providing a positioning element, this solution solves the problem of inaccurate positioning of the L- and N-guide strips during installation. In particular, the positioning element is arranged on the rear of the socket unit to ensure precise positioning of the L- and N-guide strips during installation.During installation, the L- and N-conductors are first positioned on the back of one socket unit using positioning elements. Then, the other socket unit is securely connected, clamping the L- and N-conductors between the two sets of socket units. This design not only simplifies the installation process but also improves stability and accuracy, thus resolving the complex and unstable installation problems inherent in existing technologies.

[0010] Preferably, the L-conductor strip and the N-conductor strip both comprise two metal discs that abut each other and are firmly connected, wherein at least one metal disc is designed as a wave shape, such that a socket is formed between the two metal discs when the two metal discs abut each other and are firmly connected; wherein the positioning element on the rear side of the socket unit is designed so that it can be inserted into a positioning column in the socket; wherein, during installation, the L-conductor strip and the N-conductor strip on the rear side of one socket unit are positioned based on the insertion of the positioning column in the socket, and, during the firm connection of the other socket unit, the positioning column on the rear side of this socket unit is also inserted into the socket of the L-conductor strip and N-conductor strip.In this solution, the L-shaped and N-shaped guide strips are held together by two metal discs and are firmly connected. At least one of these discs is corrugated to form the mounting hole, and the positioning element on the back of the socket unit is a positioning column that can be inserted into the mounting hole. This design allows for precise positioning of the guide strip during installation by inserting the positioning column into the mounting hole, ensuring a stable installation of the guide strip on the back of the socket unit. This structure provides a more reliable fixation of the guide strip between the two sets of socket units, preventing displacement or loosening of the guide strip during installation.

[0011] Preferably, the two metal discs of the L- and N-conductor strips are identically bent at a connection hole on one of their upper and lower end faces to form a contact disc each, with the contact discs of the two metal discs being combined to form the connector; each socket unit being provided with a connection hole corresponding to the connector at the current-tapping position. In this solution, the two metal discs of the L- and N-conductor strips are identically bent at a connection hole on one of their upper and lower end faces to form a contact disc each. This design allows the contact disc to be in close contact with the current-tapping position of the socket unit to ensure stable current transmission.By combining the contact discs of the two metal discs into a single connector, this design increases the mechanical strength and reliability of the electrical connection. Each socket unit is equipped with a corresponding insertion slot at the current-tapping position, allowing the connector to be inserted precisely into the slot, ensuring accuracy and stability of the connection. Through the interplay of these technical features, this solution effectively resolves the issue of connecting the contact discs of the L and N terminals and the current-tapping position of the socket unit within a double-sided socket module, thus guaranteeing stable current transmission and reliable socket operation.

[0012] Preferably, the socket unit comprises a socket body and a lower holder, which is rigidly connected to the rear of the socket body. The L- and N-conductors are located on the rear of the lower holder, and both the socket body and the lower holder are provided with corresponding upper and lower insertion openings. The current extraction position is located on the socket body, and a safety door component is arranged between the upper insertion opening of the socket body and the lower insertion opening of the lower holder. In this solution, the rigid connection of the socket body and the lower holder ensures the stability of the structure, while the positioning of the L- and N-conductors on the lower holder allows for the determination of the conductor position and reduces installation complexity.The upper and lower insertion openings on the socket body and the lower holder correspond to each other, ensuring the accuracy and reliability of the electrical connection. This design, in which the current-tapping position is located on the socket body and connected to the lower insertion opening of the lower holder via the safety door component, not only increases operational safety but also facilitates maintenance and replacement. Overall, this design effectively solves the problem of connecting the socket body and the lower holder in the double-sided socket module, while simultaneously ensuring effective adjustment of the current-tapping position and the safety door component, thus increasing the product's safety and reliability.

[0013] Preferably, the current pickup position is designed to form a current pickup groove on the socket body, with the upper insertion opening located on the underside of the current pickup groove. This technical solution specifically provides a German-style socket in which the current pickup position is designed as a current pickup groove. The current pickup position is formed directly on the socket body to create a current pickup groove, and the insertion opening is located on the underside of the current pickup groove. This design simplifies the structure of the current pickup position and reduces additional components, thereby decreasing the complexity of the overall structure. Simultaneously, the design of the current pickup groove allows for a more compact current pickup position, reducing the space requirement and contributing to a reduction in the overall thickness of the double-sided socket module.

[0014] Preferably, each current-tapping position of the socket unit is equipped with a grounding contact disc, and an electrical conductor strip, which is connected to each grounding contact disc, is further provided in the socket unit. The grounding contact disc is U-shaped, with two side openings arranged on one side wall of the current-tapping groove, the two U-shaped ends of the grounding contact disc projecting into the current-tapping groove through these two side openings. By introducing the U-shaped grounding contact disc and electrical conductor strip, this solution solves the problem of connecting the grounding contact disc and the current-tapping groove in the double-sided socket module. The U-shaped grounding contact disc is designed such that it can project into the current-tapping groove through both side openings on the side wall, thereby ensuring a stable connection between the grounding contact disc and the plug-in opening in the current-tapping groove.The electrical conductor strip is connected to the grounding contact disc, further enhancing the reliability of the grounding. This design not only simplifies the installation process of the grounding contact disc but also improves the stability and safety of the grounding.

First example:

[0021] As in Fig. 1 to Fig. As shown in Figure 8, this embodiment relates to a double-sided socket module comprising two groups of socket units 1, arranged opposite each other and rigidly connected, an L-type conductor 2, and an N-type conductor 3, which are provided between the two groups of socket units 1. The two groups of socket units 1 are consistently equipped with at least one current-tapping position. In particular, the present embodiment includes, but is not limited to, those shown in the Fig. Figures 1 to 3 show that the two groups of socket units 1 are consistently equipped with one to three current-tapping positions. With the two groups of socket units 1 being rigidly connected backwards, the contacts in the socket unit 1 are in conductive contact with the L-conductors 2 and the N-conductors 3. In the double-sided socket module, two groups of socket units 1 are arranged opposite each other and rigidly connected, and the L-conductors 2 and N-conductors 3 are located between the two groups of socket units 1. In this solution, the double-sided socket module is connected by a rigid back-to-back connection of two groups of socket units 1, and when the two groups of socket units 1 are rigidly connected backwards, the contacts in the socket unit 1 are in conductive contact with the L-conductors 2 and the N-conductors 3 to ensure stable current transmission.In this way, on the one hand, two groups of socket units 1 can be rigidly connected backwards without the aid of a socket housing, and on the other hand, the installation structure can be simplified.

[0022] Preferably, the two groups of socket units 1 are arranged opposite each other and can be clamped together and snap together. By arranging the two groups of socket units 1 opposite each other and being clamped together and able to snap together, the technical solution solves the problem of a stable connection when two groups of socket units 1 are arranged opposite each other in the double-sided socket module. In particular, when two groups of socket units 1 are arranged opposite each other, a stable connection is achieved by clamping and snapping together, thus avoiding the problems of the greater thickness and the complicated structure of the conventional double-sided socket module caused by the mounting of the socket plate to the socket housing. This design not only simplifies the structure but also improves the stability and reliability of the socket module. Fig. In the specific embodiment shown in Figure 4, two groups of bushing units 1 are constructed as molded parts with the same structure, wherein the bushing units 1 are each provided on their rear sides with a clamping slot 11 and a clamping block 12, wherein a clamping hook 13 is provided within the clamping slot and the clamping block is provided with a clamping opening 14; wherein, when the two groups of bushing units 1 are rigidly connected from the rear, the clamping block of one of the bushing units 1 projects into the clamping slot of the other of the bushing units 1, and wherein the clamping hook in the clamping slot is clamped in the clamping opening of the clamping block. Because two groups of bushing units 1 are constructed as molded parts with the same structure, this solution simplifies the manufacturing process and improves ease of assembly.The fact that the socket units 1 are each provided on their rear sides with a clamping slot 11 and a clamping block 12, with a clamping hook 13 being provided within the clamping slot 11 and the clamping block 12 being provided with a clamping opening 14, so that when the two groups of socket units 1 are firmly connected from the rear, the clamping block 12 can protrude into the clamping slot 11 and the clamping hook 13 can be clamped in the clamping opening 14, thus enabling a quick and stable connection. This design not only reduces the number of installation steps but also improves the overall structural strength and stability of the socket module and effectively solves the problem of the complex structure and inconvenient installation of the conventional double-sided socket module.

[0023] Preferably, a positioning element 15 for positioning metal guide strips is provided on the rear side of the socket unit 1. During installation, the L-guide strips 2 and N-guide strips 3 are positioned by positioning elements on the rear side of one socket unit 1, and when the other socket unit 1 is permanently connected, the L-guide strips 2 and N-guide strips 3 are clamped between two groups of socket units 1. The provision of the positioning element 15 solves the problem of inaccurate positioning of the L-guide strips 2 and N-guide strips 3 during installation. In particular, the positioning element 15 is arranged on the rear side of the socket unit 1 to accurately position the L-guide strips 2 and N-guide strips 3 during installation.During installation, the L-conductors 2 and N-conductors 3 are first positioned on the back of a socket unit 1 using positioning elements 15. Then, the other socket unit 1 is firmly connected, so that the L-conductors 2 and N-conductors 3 are clamped between two groups of socket units 1. This design not only simplifies the installation process but also improves the stability and accuracy of the installation, thus solving the complex and unstable installation problems of existing technologies. In the case of... Fig. In the specific embodiment shown in Figure 6, the L-guide strip 2 and the N-guide strip 3 each comprise two metal discs 20 which abut each other and are firmly connected, wherein at least one metal disc 20 is designed as a wave shape, such that a socket 21 is formed between the two metal discs 20 when the two metal discs 20 abut each other and are firmly connected; wherein the positioning element 15 on the rear side of the socket unit 1 is designed such that it can be inserted into a positioning column in the socket 21, wherein there are several positioning columns; wherein, during installation, the L-guide strip 2 and the N-guide strip 3 on the rear side of one socket unit 1 are positioned based on the insertion of the positioning column in the socket 21, and, during the firm connection of the other socket unit 1, the positioning column on the rear side of this socket unit 1 is also inserted into the socket 21 of the L-guide strip 2 and N-guide strip 3.In this solution, the L-guide strip 2 and the N-guide strip 3 are held in contact by two metal discs 20 and are firmly connected. At least one of these metal discs 20 is corrugated to form the mounting hole 21, and the positioning element 15 on the back of the socket unit 1 is a positioning column that can be inserted into the mounting hole 21. This design allows for precise positioning of the guide strip during installation by inserting the positioning column into the mounting hole 21, ensuring a stable installation of the guide strip on the back of the socket unit 1. This structure provides a more reliable fixation of the guide strip between the two groups of socket units 1, thus preventing displacement or loosening of the guide strip during installation.

[0024] In another solution, the two metal discs 20 of the L-terminal strip 2 and N-terminal strip 3 are bent identically at a plug hole 21 on one of their upper and lower end faces to form a contact disc 22 each, wherein the contact discs 22 of the two metal discs 20 are combined to form the connector 23; wherein each socket unit 1 is provided at the current-tapping position with a plug hole corresponding to the connector 23. In this solution, the two metal discs 20 of the L-terminal strip 2 and N-terminal strip 3 are bent identically at a plug hole 21 on one of their upper and lower end faces each to form a contact disc 22. This design allows the contact disc 22 to be in close contact with the current-tapping position of the socket unit 1 to ensure stable current transmission.By combining the contact discs 22 of the two metal discs 20 to form the connector 23, this design increases the mechanical strength and reliability of the electrical connection of the connector 23. Since each socket unit 1 is provided with a plug-in opening corresponding to the connector 23 at the current-tapping position, this design allows the connector 23 to be inserted precisely into the plug-in opening, ensuring the accuracy and stability of the connection. Through the interaction of these technical features, the technical solution effectively solves the problem of connecting the contact discs 22 of the L-terminal 2 and the N-terminal 3 and the current-tapping position of the socket unit 1 in a double-sided socket module, thus ensuring stable current transmission and reliable use of the socket.

[0025] At the in Fig.In the solution shown in Figure 8, the socket unit 1 comprises a socket body 100 and a lower holder 101, which is fixedly connected to the rear of the socket body 100. The socket body 100 and the lower holder 101 can adopt any easily detachable fixed connection solution, such as a screw connection, as shown in the figures. The L-conductor 2 and N-conductor 3 are positioned on the rear of the lower holder 101, with both the socket body 100 and the lower holder 101 being provided with corresponding upper 16 and lower insertion openings 17; the current extraction position is provided on the socket body 100, with a safety door component 18 arranged between the upper insertion opening 16 of the socket body 100 and the lower insertion opening 17 of the lower holder 101.In this solution, the rigid connection between the socket body 100 and the lower holder 101 ensures the stability of the structure, while the positioning of the L-conductor 2 and N-conductor 3 on the lower holder 101 allows for precise positioning of the conductors and reduces installation complexity. The upper 16 and lower plug-in openings 17 on the socket body 100 and the lower holder 101 are aligned, ensuring the accuracy and reliability of the electrical connection. This design, in which the current-tapping position is located on the socket body 100 and connected to the lower plug-in opening 17 of the lower holder 101 by the safety door component 18, not only increases operational safety but also facilitates maintenance and replacement.Overall, this design effectively solves the problem of connecting the socket body 100 and the lower holder 101 in the double-sided socket module, while simultaneously ensuring effective adjustment of the current-tapping position and the safety door component 18, thus increasing the product's safety and reliability. In this solution, the safety door component 18 is part of the existing technology and is not described in detail here.

[0026] In this specific solution, the current extraction position is designed to form a current extraction groove 102 on the socket body 100, with the upper insertion opening 16 located on the underside of the current extraction groove 102. This technical solution specifically provides a German-style socket in which the current extraction position is designed as a current extraction groove 102. The current extraction position is formed directly on the socket body 100 to create a current extraction groove 102, and the insertion opening is located on the underside of the current extraction groove 102. This design simplifies the structure of the current extraction position and reduces additional components, thereby decreasing the complexity of the overall structure. Simultaneously, the design of the current extraction groove 102 allows for a more compact current extraction position, reducing the space requirement and contributing to a reduction in the overall thickness of the double-sided socket module.Furthermore, each current-tapping position of the socket unit 1 is equipped with a grounding contact disc 41, and an electrical conductor 4, which is connected to each grounding contact disc 41, is also provided in the socket unit 1; the grounding contact disc 41 is U-shaped, with two side openings arranged on one side wall of the current-tapping groove 102, the two U-shaped ends of the grounding contact disc 41 projecting into the current-tapping groove 102 through two side openings. By introducing the U-shaped grounding contact disc 41 and the electrical conductor 4, this solution solves the problem of connecting the grounding contact disc 41 and the current-tapping groove 102 in the double-sided socket module.The U-shaped grounding contact disc 41 is designed to extend through both side openings on the side wall of the current tap groove 102 into the current tap groove 102, thus ensuring a stable connection between the grounding contact disc 41 and the plug opening in the current tap groove 102. The E-conductor strip 4 is connected to the grounding contact disc 41, further increasing the reliability of the grounding. This design not only simplifies the installation process of the grounding contact disc 41 but also improves the stability and safety of the grounding. Second example:
