Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a power socket and its double-sided socket module. Background Technology

[0002] Sockets, as common electrical devices, are widely used in daily life and office environments. To increase the number of power outlets, existing multi-outlet power strips typically have multiple power outlets arranged in a matrix on one side of the cross-section. For example, patents with publication number "CN208522151U" all involve double-sided sockets, where power outlets are symmetrically arranged on opposite ends of the socket. However, these existing double-sided sockets usually use a socket housing as a carrier, with power outlets on both sides, and the socket panel fixed to the housing, sharing a common metal conductive strip inside the housing. This structure has the following problems:

[0003] 1. Complex structure: Existing double-sided sockets require a complex housing structure to fix the socket panel and conductive strip, which increases the difficulty of manufacturing and assembly.

[0004] 2. Larger thickness: To avoid the risk of interference when drawing power from double-sided sockets, existing double-sided sockets are usually quite thick, which is not conducive to saving space.

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

[0006] To address the aforementioned problems, the primary objective of this invention is to provide a double-sided socket module that eliminates the need for a socket housing to fix two sets of socket units facing opposite directions, and simplifies the installation structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A double-sided socket module is characterized in that it includes two sets of socket units that are arranged and fixedly connected back to back, and an L-pole conductive strip and an N-pole conductive strip disposed between the two sets of socket units. Both sets of socket units are equipped with at least one potential tap. When the two sets of socket units are fixedly connected back to back, the contacts in the socket units are connected to the L-pole conductive strip and the N-pole conductive strip.

[0009] This utility model adopts the above-mentioned technical solution, which relates to a double-sided socket module. This double-sided socket module consists of two sets of socket units arranged and fixedly connected back-to-back, and an L-pole conductive strip and an N-pole conductive strip disposed between the two sets of socket units. In this solution, the double-sided socket module uses two sets of socket units connected back-to-back. When the two sets of socket units are fixed back-to-back, the contacts within the socket units are connected to the L-pole and N-pole conductive strips, ensuring stable current transmission. Thus, on the one hand, it eliminates the need for a socket housing to fix the two sets of socket units back-to-back, and on the other hand, it simplifies the installation structure.

[0010] Preferably, the two sets of socket units are arranged back-to-back and can be snapped together. This technical solution solves the problem of stable connection when the two sets of socket units are arranged back-to-back and snapped together. Specifically, when the two sets of socket units are arranged back-to-back, a stable connection is achieved through snap-fit, avoiding the problems of large thickness and complex structure caused by the socket panel being fixed to 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. Each socket unit has a slot and a locking block on its back. The slot contains a hook, and the locking block has a latch. When the two sets of socket units are fixed together back-to-back, the locking block of one socket unit extends into the slot of the other, and the hook in the slot engages with the latch on the locking block. This design simplifies the manufacturing process and improves assembly convenience by constructing the two sets of socket units as identical molded parts. The slot and locking block on the back of the socket units, along with the hook in the slot and the latch on the block, allow for a quick and secure connection when the two sets of socket units are fixed together back-to-back, achieved by the locking block extending into the slot and the hook engaging with the latch. This design not only reduces 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, the back of the socket unit is provided with a positioning component for positioning the metal conductive strip. During installation, the L-pole and N-pole conductive strips are positioned on the back of one socket unit by the positioning component. When the other socket unit is fixedly connected, the L-pole and N-pole conductive strips are fixedly clamped between the two sets of socket units. This solution solves the problem of inaccurate positioning of the L-pole and N-pole conductive strips during installation by setting the positioning component. Specifically, the positioning component is located on the back of the socket unit to accurately position the L-pole and N-pole conductive strips during installation. During installation, the L-pole and N-pole conductive strips are first positioned on the back of one socket unit by the positioning component, and then the other socket unit is fixedly connected, so that the L-pole and N-pole conductive strips 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 installation, thereby solving the problems of complex and unstable installation in the prior art.

[0013] Preferably, both the L-pole conductive strip and the N-pole conductive strip include two metal sheets that are bonded together, at least one of which is corrugated to form a socket between the two metal sheets when they are bonded together. The positioning component on the back of the socket unit is configured as a positioning post that can be inserted into the socket. During installation, the L-pole conductive strip and the N-pole conductive strip are positioned on the back of one of the socket units based on the positioning post inserted into the socket. When the other socket unit is fixed in place, the positioning post on the back of that socket unit is also inserted into the socket of the L-pole conductive strip and the N-pole conductive strip. In this design, the L-pole conductive strip and the N-pole conductive strip are bonded together by two metal sheets, at least one of which is corrugated to form a socket. The positioning component on the back of the socket unit is a positioning post that can be inserted into the socket. This design allows the conductive strip to be accurately positioned during installation by inserting the positioning post into the socket, ensuring the stable installation of the conductive strip on the back of the socket unit. This structure makes the fixing of the conductive strip between the two sets of socket units more reliable, avoiding the problem of displacement or loosening that may occur during the installation process.

[0014] Preferably, the two metal pieces of the L-pole and N-pole conductive strips are bent at one of the insertion holes on their upper and lower end faces to form contact pieces, and the contact pieces of the two metal pieces are combined to form a connector; each socket unit has a socket corresponding to the connector at its potential tapping point. In this scheme, the two metal pieces of the L-pole and N-pole conductive strips are bent at one of the insertion holes on their upper and lower end faces to form contact pieces. This design allows the contact pieces to make close contact with the potential tapping point of the socket unit, ensuring stable current transmission. The combination of the two metal pieces to form a connector improves the mechanical strength and electrical connection reliability of the connector. The socket unit has a socket corresponding to the connector at its potential tapping point, which allows the connector to be accurately inserted into the socket, ensuring the accuracy and stability of the connection. Through the cooperation of these technical features, this technical solution effectively solves the connection problem between the contact pieces of the L-pole and N-pole conductive strips and the potential tapping point of the socket unit in a 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 fixed to the back of the socket body. The L-pole conductive strip and N-pole conductive strip are positioned on the back of the bottom bracket. Both the socket body and the bottom bracket have corresponding upper and lower insertion ports. The potential tap is located on the socket body, and a safety door assembly is provided between the upper insertion port of the socket body and the lower insertion port of the bottom bracket. In this design, the fixed connection between the socket body and the bottom bracket ensures structural stability. Simultaneously, the positioning of the L-pole and N-pole conductive strips on the bottom bracket fixes their positions, reducing installation complexity. The corresponding upper and lower insertion ports on the socket body and bottom bracket ensure accurate and reliable electrical connections. The potential tap is located on the socket body and connected to the lower insertion port of the bottom bracket via the safety door assembly. This design not only improves safety but also facilitates maintenance and replacement. Overall, this structural design effectively solves the connection problem between the socket body and the bottom bracket in a double-sided socket module, while ensuring the effective placement of the potential tap and safety door assembly, thus improving product safety and reliability.

[0016] Preferably, the tapping potential is constructed as a tapping groove formed on the socket body, with the socket located on the bottom surface of the tapping groove. Specifically, this technical solution provides a German-style socket where the tapping potential is constructed in the form of a tapping groove. The tapping potential is directly formed on the socket body to create the tapping groove, and the socket is located on the bottom surface of the tapping groove. This design simplifies the structure of the tapping potential, reduces additional components, and thus reduces the complexity of the overall structure. Simultaneously, the tapping groove design makes the tapping potential more compact, reduces space occupation, and helps to reduce the overall thickness of the double-sided socket module.

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

[0018] The second objective of this utility model is to provide a power socket, characterized in that it includes the double-sided socket module described above. Attached Figure Description

[0032] Example 1:

[0033] like Figures 1-8 As shown, this embodiment relates to a double-sided socket module, including two sets of socket units 1 arranged back-to-back and fixedly connected, and an L-pole conductive strip 2 and an N-pole conductive strip 3 disposed between the two sets of socket units 1. Both sets of socket units 1 are uniformly equipped with at least one potential tap. Specifically, this embodiment includes, but is not limited to, the following... Figures 1-3 As shown, both sets of socket units 1 are equipped with 1 to 3 potential taps. When the two sets of socket units 1 are fixed back to back, the contacts inside the socket unit 1 are connected to the L-pole conductive strip 2 and the N-pole conductive strip 3. This double-sided socket module uses two sets of socket units 1 that are fixed back to back, and the L-pole conductive strip 2 and the N-pole conductive strip 3 located between the two sets of socket units 1. In this scheme, the double-sided socket module is connected by two sets of socket units 1 fixed back to back, and when the two sets of socket units 1 are fixed back to back, the contacts inside the socket unit 1 are connected to the L-pole conductive strip 2 and the N-pole conductive strip 3, ensuring stable current transmission. In this way, on the one hand, it is not necessary to use a socket housing to fix the two sets of socket units 1 back to back, and on the other hand, the installation structure is simplified.

[0034] Preferably, the two sets of socket units 1 are arranged back-to-back and can be snapped together. This solution, by arranging the two sets of socket units 1 back-to-back and using a snap-fit ​​method, solves the problem of a stable connection when the two sets of socket units 1 are arranged back-to-back in a double-sided socket module. Specifically, when the two sets of socket units 1 are arranged back-to-back, a stable connection is achieved through a snap-fit ​​method, avoiding the problems of large thickness and complex structure caused by the socket panel being fixed to 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. Figure 4 In the specific implementation shown, the two sets of socket units 1 are constructed as identical molded parts. A slot 11 and a locking block 12 are provided on the back of each socket unit 1. A hook 13 is provided within the slot, and a locking slot 14 is provided on the locking block. When the two sets of socket units 1 are fixedly connected back-to-back, the locking block of one socket unit 1 extends into the slot of the other socket unit 1, and the hook in the slot engages with the locking slot on the locking block. This solution simplifies the manufacturing process and improves assembly convenience by constructing the two sets of socket units 1 as identical molded parts. The slot 11 and locking block 12 on the back of the socket unit 1, along with the hook 13 within the slot 11 and the locking slot 14 on the locking block 12, enable a quick and stable connection when the two sets of socket units 1 are fixedly connected back-to-back, by having the locking block 12 extend into the slot 11 and the hook 13 engage with the locking slot 14. This design not only reduces installation steps but also improves the overall structural strength and stability of the socket module, effectively solving the problem of complex structure and inconvenient installation of traditional double-sided socket modules.

[0035] In a preferred embodiment, a positioning component 15 for positioning the metal conductive strip is provided on the back of the socket unit 1. During installation, the L-pole conductive strip 2 and the N-pole conductive strip 3 are positioned on the back of one of the socket units 1 by the positioning component 15. When the other socket unit 1 is fixedly connected, the L-pole conductive strip 2 and the N-pole conductive strip 3 are fixedly clamped between the two sets of socket units 1. This embodiment solves the problem of inaccurate positioning of the L-pole conductive strip 2 and the N-pole conductive strip 3 during installation by providing the positioning component 15. Specifically, the positioning component 15 is provided on the back of the socket unit 1 to accurately position the L-pole conductive strip 2 and the N-pole conductive strip 3 during installation. During installation, the L-pole conductive strip 2 and the N-pole conductive strip 3 are first positioned on the back of one of the socket units 1 by the positioning component 15, and then the other socket unit 1 is fixedly connected, so that the L-pole conductive strip 2 and the N-pole conductive strip 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, thereby solving the problems of complex and unstable installation in the prior art. Figure 6 In the specific embodiment shown, both the L-polar conductive strip 2 and the N-polar conductive strip 3 include two metal sheets 20 that are bonded together. At least one of the metal sheets 20 is corrugated, so that when the two metal sheets 20 are bonded together, a socket 21 is formed between them. The positioning component 15 on the back of the socket unit 1 is configured as a positioning post that can be inserted into the socket 21. There are multiple positioning posts in the figure. During installation, the L-polar conductive strip 2 and the N-polar conductive strip 3 are positioned on the back of one of the socket units 1 based on the positioning posts inserted into the socket 21. When another socket unit 1 is bonded, the positioning posts on the back of that socket unit 1 are also inserted into the socket 21 of the L-polar conductive strip 2 and the N-polar conductive strip 3. In this embodiment, the L-polar conductive strip 2 and the N-polar conductive strip 3 are bonded together by two metal sheets 20, at least one of which is corrugated to form the socket 21. The positioning component 15 on the back of the socket unit 1 is a positioning post that can be inserted into the socket 21. This design allows the conductive strip to be accurately positioned during installation by inserting the positioning pin into the socket 21, ensuring a secure installation of the conductive strip on the back of the socket unit 1. This structure makes the fixing of the conductive strip between the two sets of socket units 1 more reliable, avoiding potential misalignment or loosening issues during installation.

[0036] In a further embodiment, the two metal pieces 20 of the L-polar conductive strip 2 and the N-polar conductive strip 3 are bent at one of the insertion holes 21 on their upper and lower end faces to form contact pieces 22. The contact pieces 22 of the two metal pieces 20 are combined to form a connector 23. Each socket unit 1 has a socket corresponding to the connector 23 at its potential extraction point. In this embodiment, the two metal pieces 20 of the L-polar conductive strip 2 and the N-polar conductive strip 3 are bent at one of the insertion holes 21 on their upper and lower end faces to form contact pieces 22. This design allows the contact pieces 22 to make close contact with the potential extraction point of the socket unit 1, ensuring stable current transmission. The combination of the contact pieces 22 of the two metal pieces 20 to form the connector 23 improves the mechanical strength and electrical connection reliability of the connector 23. The design of the connector 23 corresponding to the connector 23 at its potential extraction point ensures that the connector 23 can be accurately inserted into the socket, ensuring the accuracy and stability of the connection. Through the synergy of these technical features, this technical solution effectively solves the connection problem between the contact pieces 22 of the L-pole conductive strip 2 and the N-pole conductive strip 3 in the double-sided socket module and the potential extraction of the socket unit 1, ensuring stable current transmission and reliable use of the socket.

[0037] In such Figure 8 In the illustrated scheme, the socket unit 1 includes a socket body 100 and a bottom bracket 101 fixed to the back of the socket body 100. The socket body 100 and the bottom bracket 101 can be connected using any convenient assembly / disassembly method; for example, the figure shows a screw connection. The L-pole conductive strip 2 and N-pole conductive strip 3 are positioned on the back of the bottom bracket 101. Both the socket body 100 and the bottom bracket 101 have corresponding upper and lower sockets 16 and 17. Potential tapping is located 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 scheme, the fixed connection design between the socket body 100 and the bottom bracket 101 ensures structural stability. Simultaneously, the positioning of the L-pole conductive strip 2 and N-pole conductive strip 3 on the bottom bracket 101 fixes the position of the conductive strips, reducing installation complexity. The upper socket 16 and lower socket 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 potential tap is located on the socket body 100 and connected to the lower socket 17 of the bottom bracket 101 via the safety door assembly 18. This design not only improves safety during 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 a double-sided socket module, while ensuring the effective setting of the potential tap and the safety door assembly 18, thus improving the safety and reliability of the product. In this solution, the safety door assembly 18 is prior art and will not be described in detail here.

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