Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and particularly to a power socket and a double-sided socket module thereof. Background Art

[0002] As a common electrical device, sockets have been widely used in daily life and office environments. In order to increase the power-taking positions of sockets, in the prior art, multiple sockets in a row usually arrange multiple power-taking jacks in a matrix on one side section. For example, patents with the publication number "CN208522151U" all relate to double-sided sockets, that is, power-taking jacks are symmetrically arranged on the opposite end faces of the socket. However, these prior art double-sided sockets usually use the socket housing as a carrier, with power-taking jacks arranged on both sides. The socket panel is fixed to the housing, and metal conductive bars are shared inside the housing. This structure has the following problems:

[0003] 1. Complex structure: The existing double-sided sockets require a complex housing structure to fix the socket panel and conductive bars, increasing the difficulty of manufacturing and assembly.

[0004] 2. Large thickness: In order to avoid the risk of interference when taking power from double-sided jacks, the existing double-sided sockets usually have a large thickness, which is not conducive to saving space.

[0005] 3. Inconvenient installation: The positioning and fixing methods of the conductive bars in the prior art are relatively cumbersome, resulting in low installation efficiency. Therefore, there is an urgent need for a double-sided socket module with a simple structure, a small thickness, and convenient installation to solve the above problems. Summary of the Invention

[0006] In order to solve the above problems, the first object of the present invention is to provide a double-sided socket module, which on the one hand can fix two sets of socket units facing away from each other without relying on a socket housing, and on the other hand can simplify the installation structure.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A double-sided socket module, characterized in that: it includes two sets of socket units arranged back to back and fixedly connected, and an L-pole conductive bar and an N-pole conductive bar arranged between the two sets of socket units. Both sets of socket units are uniformly equipped with at least one power-taking position; when the two sets of socket units are fixedly connected back to back, the contacts in the socket units are electrically connected to the L-pole conductive bar and the N-pole conductive bar.

[0009] The present invention adopts the above technical solution, which relates to a double-sided socket module. The double-sided socket module includes two sets of socket units arranged back to back and fixedly connected, as well as an L-pole conductive bar and an N-pole conductive bar disposed between the two sets of socket units. In this solution, the two sets of socket units of the double-sided socket module are connected in a back-to-back and fixedly connected manner. When the two sets of socket units are fixedly connected back to back, the contacts in the socket units are electrically connected to the L-pole conductive bar and the N-pole conductive bar, ensuring stable current transmission. In this way, on the one hand, it is not necessary to fixedly connect the two sets of socket units back to back by means of a socket housing, and on the other hand, the installation structure can be simplified.

[0010] Preferably, the two sets of socket units are arranged back to back and can be snap-fitted. This technical solution solves the problem of stable connection of the two sets of socket units when they are arranged back to back in the double-sided socket module. Specifically, when the two sets of socket units are arranged back to back, they are stably connected by snap-fitting, avoiding the problems of large thickness and complex structure caused by fixing the socket panel on the socket housing in traditional double-sided socket modules. This design not only simplifies the structure but also improves the stability and reliability of the socket module.

[0011] Preferably, the two sets of socket units are constructed as identical molded parts. A slot and a block are provided on the back surface of the socket unit. A hook is provided in the slot, and a bayonet is provided on the block. When the two sets of socket units are fixedly connected back to back, the block of one socket unit extends into the slot of the other socket unit, and the hook in the slot snaps into the bayonet on the block. This solution simplifies the manufacturing process and improves the convenience of assembly by constructing the two sets of socket units as identical molded parts. The slot and the block provided on the back surface of the socket unit, as well as the hook in the slot and the bayonet on the block, enable the two sets of socket units to be quickly and stably connected when fixedly connected back to back by the block extending into the slot and the hook snapping into the bayonet. This design not only reduces the installation steps but also improves the overall structural strength and stability of the socket module, effectively solving the problems of complex structure and inconvenient installation in traditional double-sided socket modules.

[0012] Preferably, a positioning component for positioning the metal conductive bars is provided on the back surface of the socket unit; during installation, the L - pole conductive bar and the N - pole conductive bar are positioned on the back surface of one of the socket units through the positioning component, and when the other socket unit is fixedly connected, the L - pole conductive bar and the N - pole conductive bar are fixedly clamped between the two sets of socket units. This solution solves the problem of inaccurate positioning of the L - pole conductive bar and the N - pole conductive bar during the installation process by providing a positioning component. Specifically, the positioning component is provided on the back surface of the socket unit and is used to accurately position the L - pole conductive bar and the N - pole conductive bar during installation. During installation, first, the L - pole conductive bar and the N - pole conductive bar are positioned on the back surface of one of the socket units through the positioning component, and then the other socket unit is fixedly connected, so that the L - pole conductive bar and the N - pole conductive bar are fixedly clamped between the two sets of socket units. This design not only simplifies the installation process but also improves the stability and accuracy of the installation, thus solving the problems of complex and unstable installation in the prior art.

[0013] Preferably, both the L - pole conductive bar and the N - pole conductive bar include two metal sheets that are fixedly bonded together, and at least one of the metal sheets is constructed in a corrugated shape so that when the two metal sheets are fixedly bonded together, a jack is formed between the two metal sheets; the positioning component on the back surface of the socket unit is constructed as a positioning post that can be inserted into the jack; during installation, the L - pole conductive bar and the N - pole conductive bar are positioned on the back surface of one of the socket units based on the positioning post being inserted into the jack, and when the other socket unit is fixedly connected, the positioning post on the back surface of this socket unit is also inserted into the jacks of the L - pole conductive bar and the N - pole conductive bar. In this solution, the L - pole conductive bar and the N - pole conductive bar are fixedly bonded together by two metal sheets, at least one of which is corrugated, forming a jack, and the positioning component on the back surface of the socket unit is a positioning post that can be inserted into the jack. This design enables the conductive bar to be accurately positioned by inserting the positioning post into the jack during installation, ensuring the stable installation of the conductive bar on the back surface of the socket unit. Through this structure, the fixation of the conductive bar between the two sets of socket units is more reliable, avoiding possible offset or loosening problems of the conductive bar during the installation process.

[0014] Preferably, two metal sheets of the L - pole conductive bar and the N - pole conductive bar are bent uniformly at one of the jacks on their upper and lower end faces to form contact pieces, and the contact pieces of the two metal sheets are combined to form a joint; each socket unit is provided with a socket corresponding to the joint at the power - taking position. In this solution, two metal sheets of the L - pole conductive bar and the N - pole conductive bar are bent uniformly at one of the jacks on their upper and lower end faces to form contact pieces. This design enables the contact pieces to be in close contact with the power - taking position of the socket unit, ensuring stable current transmission. The contact pieces of the two metal sheets are combined to form a joint, and this structural design improves the mechanical strength and electrical connection reliability of the joint. Each socket unit is provided with a socket corresponding to the joint at the power - taking position. This design enables the joint to be accurately inserted into the socket, ensuring the accuracy and stability of the connection. Through the mutual cooperation of these technical features, this technical solution effectively solves the connection problem between the contact pieces of the L - pole conductive bar and the N - pole conductive bar and the power - taking position of the socket unit in the double - sided socket module, ensuring stable current transmission and reliable use of the socket.

[0015] Preferably, the socket unit includes a socket body and a bottom bracket fixedly connected to the back of the socket body; the L - pole conductive bar and the N - pole conductive bar are positioned on the back surface of the bottom bracket, and corresponding upper sockets and lower sockets are provided on both the socket body and the bottom bracket; the power - taking position is set on the socket body, and a safety - door assembly is provided between the upper socket of the socket body and the lower socket of the bottom bracket. In this solution, the fixed - connection design of the socket body and the bottom bracket ensures the structural stability. At the same time, the positioning of the L - pole conductive bar and the N - pole conductive bar on the bottom bracket fixes the positions of the conductive bars, reducing the complexity during installation. The upper sockets and lower sockets on the socket body and the bottom bracket correspond to each other, ensuring the accuracy and reliability of the electrical connection. The power - taking position is set on the socket body and is connected to the lower socket of the bottom bracket through the safety - door assembly. This design not only improves the safety of use but also facilitates maintenance and replacement. Overall, this structural design effectively solves the connection problem between the socket body and the bottom bracket in the double - sided socket module, and at the same time ensures the effective setting of the power - taking position and the safety - door assembly, improving the safety and reliability of the product.

[0016] Preferably, the power - taking position is configured as a power - taking groove formed on the socket body, and the socket is provided on the bottom surface of the power - taking groove. This technical solution specifically provides a German - style socket, and the power - taking position of the German - style socket is constructed in the form of a power - taking groove. The power - taking position is directly formed on the socket body to form a power - taking groove, and the socket is provided on the bottom surface of the power - taking groove. This design simplifies the structure of the power - taking position, reduces additional components, and thus reduces the complexity of the overall structure. At the same time, the design of the power - taking groove makes the power - taking position more compact, reduces the occupied space, and helps to reduce the overall thickness of the double - sided socket module.

[0017] Preferably, each power-taking position of the socket unit is equipped with a grounding contact piece, and an E-pole conductive bar connected to each grounding contact piece is further provided in the socket unit; the grounding contact piece is U-shaped, two side openings are provided on the side wall of the power-taking groove, and the U-shaped ends of the grounding contact piece extend into the power-taking groove through the two side openings. In this solution, by introducing the U-shaped grounding contact piece and the E-pole conductive bar, the connection problem between the grounding contact piece and the power-taking groove in the double-sided socket module is solved. The design of the U-shaped grounding contact piece enables it to extend into the power-taking groove through the two side openings on the side wall of the power-taking groove, thereby ensuring a stable connection between the grounding contact piece and the socket in the power-taking groove. The E-pole conductive bar is connected to the grounding contact piece, further enhancing the reliability of grounding. This design not only simplifies the installation process of the grounding contact piece, but also improves the stability and safety of grounding.

[0032] Embodiment 1:

[0033] As Figures 1 to 8 shown, this embodiment relates to a double-sided socket module, including two sets of socket units 1 arranged back to back and fixedly connected, as well as an L-pole conductive bar 2 and an N-pole conductive bar 3 arranged between the two sets of socket units 1. Both sets of socket units 1 are uniformly equipped with at least one potential-taking position. Specifically, this implementation scheme includes but is not limited to as Figures 1 to 3In the manner shown, each of the two sets of socket units 1 is uniformly equipped with 1 to 3 power-taking positions. When the two sets of socket units 1 are fixedly connected back to back, the contacts in the socket unit 1 are electrically connected to the L-pole conductive bar 2 and the N-pole conductive bar 3. This double-sided socket module consists of two sets of socket units 1 that are arranged back to back and fixedly connected, as well as the L-pole conductive bar 2 and the N-pole conductive bar 3 arranged between the two sets of socket units 1. In this solution, the double-sided socket module is connected by fixedly connecting the two sets of socket units 1 back to back. When the two sets of socket units 1 are fixedly connected back to back, the contacts in the socket unit 1 are electrically connected to the L-pole conductive bar 2 and the N-pole conductive bar 3, ensuring stable current transmission. In this way, on the one hand, it is not necessary to fixedly connect the two sets of socket units 1 back to back by means of the socket housing, and on the other hand, the installation structure can be simplified.

[0034] Preferably, the two sets of socket units 1 are arranged back to back and can be snap-fitted. This solution arranges the two sets of socket units 1 back to back and uses the snap-fitting method to solve the problem of stable connection when the two sets of socket units 1 in the double-sided socket module are arranged back to back. Specifically, when the two sets of socket units 1 are arranged back to back, a stable connection is achieved through snap-fitting, avoiding the problems of large thickness and complex structure caused by fixing the socket panel on the socket housing in traditional double-sided socket modules. This design not only simplifies the structure but also improves the stability and reliability of the socket module. In Figure 4 In the specific implementation shown, the two sets of socket units 1 are constructed as molded parts with the same structure. On the back surface of the socket unit 1, there are a card slot 11 and a card block 12. A hook 13 is arranged in the card slot, and a bayonet 14 is arranged on the card block. When the two sets of socket units 1 are fixedly connected back to back, the card block of one socket unit 1 extends into the card slot of the other socket unit 1, and the hook in the card slot is snapped into the bayonet on the card block. This solution simplifies the manufacturing process and improves the convenience of assembly by constructing the two sets of socket units 1 as molded parts with the same structure. The card slot 11 and the card block 12 arranged on the back surface of the socket unit 1, as well as the hook 13 in the card slot 11 and the bayonet 14 on the card block 12, enable the two sets of socket units 1 to achieve a quick and stable connection when fixedly connected back to back by the card block 12 extending into the card slot 11 and the hook 13 being snapped into the bayonet 14. This design not only reduces the installation steps but also improves the overall structural strength and stability of the socket module, effectively solving the problems of complex structure and inconvenient installation in traditional double-sided socket modules.

[0035] In a preferred embodiment, a positioning member 15 for positioning the metal conductive bars is provided on the back surface of the socket unit 1. During installation, the L-pole conductive bar 2 and the N-pole conductive bar 3 are positioned on the back surface of one of the socket units 1 through the positioning member 15, and when the other socket unit 1 is fixedly connected, the L-pole conductive bar 2 and the N-pole conductive bar 3 are fixedly clamped between the two sets of socket units 1. By providing the positioning member 15, this solution solves the problem of inaccurate positioning of the L-pole conductive bar 2 and the N-pole conductive bar 3 during the installation process. Specifically, the positioning member 15 is provided on the back surface of the socket unit 1 for accurately positioning the L-pole conductive bar 2 and the N-pole conductive bar 3 during the installation process. During installation, first, the L-pole conductive bar 2 and the N-pole conductive bar 3 are positioned on the back surface of one of the socket units 1 through the positioning member 15, and then the other socket unit 1 is fixedly connected, so that the L-pole conductive bar 2 and the N-pole conductive bar 3 are fixedly clamped between the two sets 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 problems of complex and unstable installation in the prior art. In Figure 6 In the specific embodiment shown, both the L-pole conductive bar 2 and the N-pole conductive bar 3 include two metal sheets 20 that are bonded and fixedly connected, and at least one of the metal sheets 20 is constructed as a corrugated shape so that when the two metal sheets 20 are bonded and fixedly connected, a jack 21 is formed between the two metal sheets 20. The positioning member 15 on the back surface of the socket unit 1 is constructed as a positioning post that can be inserted into the jack 21, and there are multiple positioning posts shown in the figure. During installation, the L-pole conductive bar 2 and the N-pole conductive bar 3 are positioned on the back surface of one of the socket units 1 based on the positioning posts being inserted into the jacks 21, and when the other socket unit 1 is fixedly connected, the positioning posts on the back surface of this socket unit 1 are also inserted into the jacks 21 of the L-pole conductive bar 2 and the N-pole conductive bar 3. In this solution, the L-pole conductive bar 2 and the N-pole conductive bar 3 are bonded and fixedly connected by two metal sheets 20, at least one of the metal sheets 20 is corrugated, forming the jack 21, and the positioning member 15 on the back surface of the socket unit 1 is a positioning post that can be inserted into the jack 21. This design enables the conductive bars to be accurately positioned by inserting the positioning posts into the jacks 21 during installation, ensuring the stable installation of the conductive bars on the back surface of the socket unit 1. Through this structure, the fixation of the conductive bars between the two sets of socket units 1 is more reliable, avoiding possible offset or loosening problems of the conductive bars during the installation process.

[0036] In a further solution, two metal sheets 20 of the L - pole conductive bar 2 and the N - pole conductive bar 3 are uniformly bent at one of the jacks 21 on their upper and lower end faces to form contact pieces 22, and the contact pieces 22 of the two metal sheets 20 are combined to form a joint 23. Each socket unit 1 is provided with a socket corresponding to the joint 23 at the power - taking position. In this solution, the two metal sheets 20 of the L - pole conductive bar 2 and the N - pole conductive bar 3 are uniformly bent at one of the jacks 21 on their upper and lower end faces to form contact pieces 22. This design enables the contact pieces 22 to be in close contact with the power - taking position of the socket unit 1, ensuring stable current transmission. The contact pieces 22 of the two metal sheets 20 are combined to form a joint 23. This structural design improves the mechanical strength and electrical connection reliability of the joint 23. Each socket unit 1 is provided with a socket corresponding to the joint 23 at the power - taking position. This design enables the joint 23 to be accurately inserted into the socket, ensuring the accuracy and stability of the connection. Through the mutual cooperation of these technical features, this technical solution effectively solves the connection problem between the contact pieces 22 of the L - pole conductive bar 2 and the N - pole conductive bar 3 and the power - taking position of the socket unit 1 in the double - sided socket module, ensuring stable current transmission and reliable use of the socket.

[0037] In the solution as Figure 8 shown, the socket unit 1 includes a socket body 100 and a bottom bracket 101 fixedly connected to the back of the socket body 100. The socket body 100 and the bottom bracket 101 can adopt any convenient disassembly and assembly fixing solution. As shown in the figure, a screw - connection method is adopted. The L - pole conductive bar 2 and the N - pole conductive bar 3 are positioned on the back surface of the bottom bracket 101. Corresponding upper sockets 16 and lower sockets 17 are provided on both the socket body 100 and the bottom bracket 101. The power - taking position is set on the socket body 100, and a safety - door assembly 18 is provided between the upper socket 16 of the socket body 100 and the lower socket 17 of the bottom bracket 101. In this solution, the fixed - connection design of the socket body 100 and the bottom bracket 101 ensures the structural stability. At the same time, the positioning of the L - pole conductive bar 2 and the N - pole conductive bar 3 on the bottom bracket 101 makes the position of the conductive bars fixed, reducing the complexity during installation. The upper sockets 16 and the lower sockets 17 on the socket body 100 and the bottom bracket 101 correspond to each other, ensuring the accuracy and reliability of the electrical connection. The power - taking position is set on the socket body 100 and is connected to the lower socket 17 of the bottom bracket 101 through the safety - door assembly 18. This design not only improves the safety of use but also facilitates maintenance and replacement. Overall, this structural design effectively solves the connection problem between the socket body 100 and the bottom bracket 101 in the double - sided socket module, and at the same time ensures the effective setting of the power - taking position and the safety - door assembly 18, improving the safety and reliability of the product. In this solution, the safety - door assembly 18 belongs to the prior art and will not be described in detail here.

[0038] In a specific solution, the power-taking potential is configured as a power-taking groove 102 formed on the socket body 100, and the upper socket 16 is arranged on the bottom surface of the power-taking groove 102. This technical solution specifically provides a German socket, and the power-taking potential of the German socket is constructed in the form of the power-taking groove 102. The power-taking potential is directly formed on the socket body 100 to form the power-taking groove 102, and the socket is arranged on the bottom surface of the power-taking groove 102. This design simplifies the structure of the power-taking potential, reduces additional components, and thus reduces the complexity of the overall structure. At the same time, the design of the power-taking groove 102 makes the power-taking potential more compact, reduces the occupied space, and helps to reduce the overall thickness of the double-sided socket module. Further, each power-taking potential of the socket unit 1 is provided with a grounding contact piece 41, and an E-pole conductive bar 4 connected to each grounding contact piece 41 is also arranged in the socket unit 1. The grounding contact piece 41 is U-shaped, and two side openings are arranged on the side wall of the power-taking groove 102. The U-shaped two ends of the grounding contact piece 41 extend into the power-taking groove 102 through the two side openings. In this solution, by introducing the U-shaped grounding contact piece 41 and the E-pole conductive bar 4, the connection problem between the grounding contact piece 41 and the power-taking groove 102 in the double-sided socket module is solved. The design of the U-shaped grounding contact piece 41 enables it to extend into the power-taking groove 102 through the two side openings on the side wall of the power-taking groove 102, thereby ensuring the stable connection between the grounding contact piece 41 and the socket in the power-taking groove 102. The E-pole conductive bar 4 is connected to the grounding contact piece 41, further enhancing the reliability of grounding. This design not only simplifies the installation process of the grounding contact piece 41 but also improves the stability and safety of grounding.
