Description

Technical Field

[0001] This utility model belongs to the field of power strip technology, specifically relating to an expandable power strip that can expand socket space. Background Technology

[0002] With the rapid popularization of modern home electronic devices, the demand for power sockets has exploded. Traditional fixed sockets have obvious design flaws: on the one hand, the fixed number of sockets leads to insufficient flexibility in use, and when multiple devices need to be powered at the same time, users often need to purchase additional power strips or frequently change plugs; on the other hand, the oversized sockets designed to increase the number of sockets seriously occupy valuable space resources, especially when used in small spaces such as office desks and bedside tables, this contradiction is particularly prominent.

[0003] Currently available expandable socket solutions generally suffer from the following technical defects: First, while modular splicing sockets can theoretically increase or decrease the number of sockets, in actual use, users need to manually assemble the modules, which is cumbersome and poses a risk of electric shock. Second, although expansion sockets using mechanical sliding rails can adjust the position of the sockets, they are prone to mechanical wear after long-term use, leading to poor contact or even structural failure. Third, while rotating expansion sockets solve the space occupation problem to some extent, their complex internal structure results in high production costs, and electrical safety performance is difficult to guarantee.

[0004] In-depth analysis of existing technologies reveals three key problems with these solutions: first, insufficient reliability and short lifespan of the expansion mechanism; second, poor ease of operation and unsatisfactory user experience; and third, potential electrical safety hazards and unstable contact resistance. These issues severely restrict the market promotion and practical application value of expandable sockets.

[0005] Based on the above analysis, there is an urgent need in this field to develop a new type of expandable socket. This socket should possess the following characteristics: employing a simple and reliable mechanical structure to flexibly adjust the number of sockets; minimizing size while ensuring electrical safety performance; and providing a convenient operation method so that ordinary users can easily complete expansion operations. This application presents an innovative solution to address these technical needs. Utility Model Content

[0006] This invention addresses the technical problems of existing expandable sockets, such as complex structure, inconvenient operation, and poor safety performance, by providing a simple, convenient, and reliable expandable socket power strip. Through an innovative rotating expansion mechanism, this power strip achieves flexible expansion and folding of the socket space, effectively solving the technical difficulties of low space utilization and poor expandability in traditional power strips.

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

[0008] An expandable power strip with expandable socket space includes a body having at least one main socket; and further includes:

[0009] A first extension and a second extension are rotatably attached to the body, both the first extension and the second extension being configured to rotate between at least a storage position and a joining position;

[0010] The first extension body has at least one first socket, in which a live wire contactor is disposed; the second extension body has at least one second socket, which is configured in pair with the first socket, in which a neutral wire contactor is disposed; the first and second extension bodies are both rotated to the splicing position, and the paired first and second sockets are spliced ​​together to form an extension socket.

[0011] Furthermore, the first extension is rotatably attached to the main body via a first pin. The first extension has a first adapter and a first extension extending in two mutually perpendicular directions. The first socket is disposed on the first extension, and the first pin is engaged with the first adapter. This L-shaped structural design allows the extension to fit snugly against the main body when stored and provides stable support when extended.

[0012] Furthermore, the second extension is rotatably attached to the main body via a second pin. The second extension has a second adapter and a second extension extending in two mutually perpendicular directions. The second socket is disposed on the second extension, and the second pin is engaged with the second adapter. This symmetrical design ensures the overall balance and aesthetics of the power strip.

[0013] Furthermore, at the assembly position, the first extension and the second extension are arranged side by side and parallel to each other. This arrangement ensures that the assembled extension socket faces the same direction as the main socket, making it convenient for the user.

[0014] Furthermore, the first adapter portion is provided with a first adapter sleeve that makes electrical contact with the first pin. The live wire contactor is electrically connected to the first adapter sleeve, and the first pin is electrically connected to the main socket. This conductive structure is made of a highly conductive copper alloy material to ensure good conductivity in terms of contact resistance.

[0015] Furthermore, a second adapter sleeve is provided within the second adapter section, which is in electrical contact with the second pin. The neutral contactor is electrically connected to the second adapter sleeve, and the second pin is electrically connected to the main socket. This design achieves a reliable electrical connection between the rotating component and the fixed component.

[0016] Furthermore, both the first and second extensions are configured in an L-shape. This shape design ensures structural strength while optimizing space utilization.

[0017] Furthermore, the main body defines a storage space on each of its left and right sides, where the first and second extensions are respectively stored. The storage spaces are designed to be dustproof, effectively protecting the sockets from contamination.

[0018] Furthermore, one end of the main body defines another storage space, in which the connecting portions of the first and second extensions are both stored in the assembled position. This design allows the power strip to maintain a neat appearance even in its extended state.

[0019] Furthermore, the first extension body has at least three first sockets, and the second extension body has the same number of second sockets. The first and second sockets are combined to form a two-phase socket. This configuration can be flexibly adjusted according to actual needs.

[0020] The expandable socket space extension strip proposed in this utility model effectively solves the technical problems of existing expandable sockets, such as complex structure, inconvenient operation, and poor safety performance, through a series of innovative designs. Its beneficial effects are specifically reflected in the following aspects:

[0021] This invention employs a design where the first and second extension bodies are rotatably attached to the main body. Through their coordinated rotation, the number of sockets can be flexibly adjusted. This design not only improves the expandability of the socket but also significantly extends its mechanical lifespan, far exceeding that of similar products. Users can easily increase or decrease the number of sockets according to their actual needs, meeting diverse electricity requirements.

[0022] Both the first and second extensions are designed in an L-shape, with the adapter and extension sections arranged at a 90-degree angle. This design allows them to fit snugly against the main body when stored, greatly reducing the overall size and improving space utilization; while providing stable support when extended, it ensures the stability of the extension socket and avoids wobbling after unfolding.

[0023] This invention employs a sliding contact method between the adapter sleeve and the pin shaft, combined with an elastic contact design, to ensure reliable electrical connection during rotation. The live wire contactor and the neutral wire contactor are electrically connected to the first and second adapter sleeves respectively, and then connected to the main socket via the pin shaft, forming a stable electrical circuit. This design effectively reduces contact resistance and improves electrical safety performance.

[0024] The operation design of this utility model is very user-friendly. Users can complete the expansion operation with one hand. The operation torque is small, and the ease of use is greatly improved, making it easy for the elderly and children to use.

[0025] Through its carefully designed storage space, this invention maintains a neat and aesthetically pleasing appearance when stored, while also improving space utilization. The storage spaces on both sides of the main body are used to store the first and second extension units, while the storage space at one end of the main body is used to store the connecting part between the two, ensuring that the product maintains a good user experience and visual appeal in both extended and stored states.

[0026] This invention provides a modular expansion solution, allowing users to configure different numbers of expansion sockets according to their actual needs. This design not only improves product flexibility but also reduces production costs, making the product more in line with market demands.

[0027] In summary, this utility model of an expandable socket power strip, through a series of innovative designs, successfully solves the long-standing technical problems in the field of expandable sockets, such as low space utilization, inconvenient operation, and poor electrical safety. This product not only boasts advantages such as simple structure, ease of use, and reliability, but also features excellent expandability and modular design, meeting the needs of different scenarios and providing users with an aesthetically pleasing and practical power solution.

The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0045] Example 1:

[0046] like Figures 1-9 As shown, this embodiment provides an expandable power strip with expandable socket space. The power strip adopts an innovative split-type rotating expansion mechanism. Through ingenious mechanical design and optimized electrical connection scheme, it realizes flexible expansion and efficient storage of socket space.

[0047] like Figures 1-4As shown, this embodiment provides an expandable power strip with expandable socket space, including a main body 1, a first extender 2, and a second extender 3. The main body 1 is injection molded from high-strength flame-retardant PC material, and is provided with at least one main socket 11 for connecting power cords and providing power to electronic devices. The main socket 11 is designed with child safety doors to effectively prevent children from accidentally touching it. The first extender 2 and the second extender 3 can both be rotatably attached to the main body 1, and are both configured to rotate between at least one storage position and one assembled position.

[0048] like Figures 1-2 As shown, the first extension 2 is rotatably attached to one side of the body 1 via the first pin 21, and the second extension 3 is rotatably attached to the other side of the body 1 via the second pin 31. Both the first extension 2 and the second extension 3 have an L-shaped structure.

[0049] like Figures 3-6 As shown, the first extension body 2 is rotatably connected to one side of the main body 1 via a first pin 21. The first extension body 2 adopts an integrally formed L-shaped structure, consisting of a first adapter part 22 and a first extension part 23, which are arranged perpendicularly at 90 degrees. The first adapter part 22 has a shaft hole inside for mounting the first pin 21. The first pin 21 is made of brass with a nickel-plated surface, forming a precise fit with the shaft hole, ensuring smooth rotation without causing inaccurate positioning due to excessive looseness.

[0050] The first extension section 23 has three first sockets 24 equidistantly arranged on it. Each first socket 24 is equipped with a live wire contactor. The contactor is made of phosphor bronze material, has a long insertion and removal life, and the silver plating treatment on the surface of the contactor reduces the contact resistance.

[0051] The first adapter 22 has an innovative first adapter sleeve 25 structure inside. The adapter sleeve is cylindrical and made of beryllium copper alloy. The first adapter sleeve 25 is fitted on the first pin 21 to ensure the reliability of the electrical connection.

[0052] like Figures 1-8 As shown, the second extension body 3 is rotatably connected to one side of the main body 1 via a second pin 31, and its structure is symmetrical to that of the first extension body 2. The second extension body 3 also adopts an L-shaped structure, consisting of a second adapter 32 and a second extension part 33. The second extension part 33 is provided with three second sockets 34, corresponding one-to-one with the first sockets 24. Each second socket 34 is equipped with a neutral wire contactor, whose structure is the same as the live wire contactor, but with the opposite polarity.

[0053] Both the first extension body 2 and the second extension body 3 are configured in an L-shape. This L-shaped structure design allows the extension body to fit snugly against the main body when stored, greatly reducing the overall volume and improving space utilization. When used, it provides stable support to ensure the stability of the extension socket.

[0054] The second adapter section 32 has a second adapter sleeve 35 inside, which is designed the same as the first adapter sleeve 25. The second pin 31 is connected to the neutral terminal of the main socket 11 via a wire of the same specification. All wires are insulated with flame-retardant PVC and can withstand a high temperature of 105°C.

[0055] like Figures 4-9 As shown, the first adapter portion 22 contains a first adapter sleeve 25 that is electrically in contact with the first pin 21. A live wire contactor (not shown) is electrically connected to the first adapter sleeve 25, and the first pin 21 is electrically connected to the main socket 11. Similarly, the second adapter portion 32 contains a second adapter sleeve 35 that is electrically in contact with the second pin 31. A neutral wire contactor (not shown) is electrically connected to the second adapter sleeve 35, and the second pin 31 is electrically connected to the main socket 11. This design achieves a reliable electrical connection between the rotating and fixed components, ensuring the electrical safety of the extension socket.

[0056] like Figure 9 As shown, the live wire terminal of the main socket 11 is connected to the first pin 21 via a wire, and the neutral wire terminal is connected to the second pin 31. The ground wire is connected independently and runs directly through the entire body 1. All terminals are crimped with screws to ensure reliable connection.

[0057] like Figures 3-4 The main body 1 has an extension 12 that forms a storage space for the first extension 2 and the second extension 3. The extension 12 forms a first storage space 13 and a second storage space 14 on the left and right sides, respectively. In the storage state, the first extension 2 and the second extension 3 are respectively stored in the corresponding storage space, providing sufficient space for the storage of the first extension 2 and the second extension 3.

[0058] In the storage location, the first extension body 2 and the second extension body 3 are respectively stored in the storage spaces on the left and right sides of the main body 1, making the overall structure of the power strip compact and easy to carry and store. The storage space adopts a dustproof design to effectively protect the sockets from contamination.

[0059] The extension 12 and the main body 1 also form a third storage space 15. The third storage space 15 is located at one end of the main body 1 opposite to the power cord. When the first extension 2 and the second extension 3 are in the spliced ​​position, the first adapter 22 and the second adapter 32 are both stored in the third storage space 15.

[0060] like Figures 1-9 As shown, during use, the user can hold the extension parts of the first extension 2 and the second extension 3 with one hand and rotate them outwards. The extensions rotate along the pin shaft, and when rotated to the 90-degree position, the extensions automatically lock into the spliced ​​position.

[0061] At the assembly position, the first extension 23 and the second extension 33 are accurately positioned through a precision-designed docking mechanism. This ensures that the axes of the three first sockets 24 and the three second sockets 34 are aligned, fully meeting the plug insertion and removal requirements.

[0062] In the assembled position, both the first extension 2 and the second extension 3 are rotated to form a certain angle (e.g., 90 degrees) with the main body 1, and the first extension 22 and the second extension 32 are arranged side by side and parallel to each other. At this time, the paired first socket 23 and the second socket 33 are combined to form an expansion socket for providing power to more electronic devices.

[0063] This embodiment features comprehensive safety protection measures. A non-contact position sensor is installed within the adapter section to detect whether the extension unit has rotated into place. When the extension unit is detected not fully rotated to the engagement position, the control circuit cuts off the power supply to the extension socket, ensuring electrical safety. Simultaneously, each socket is equipped with an independent overload protector. When the current exceeds the rated value, the overload protector automatically cuts off the power supply to prevent fires or equipment damage caused by overload. This design significantly improves the electrical safety performance of the power strip.

[0064] Furthermore, in this embodiment, the main body 1, the first extension 2, and the second extension 3 are all made of high-quality insulating materials, possessing excellent electrical insulation and weather resistance. Additionally, each socket is equipped with an anti-electric shock protection device (not shown in the figure), effectively preventing electric shock accidents.

[0065] This invention provides a modular expansion solution, allowing users to configure different numbers of expansion sockets according to their actual needs. This design not only improves product flexibility but also reduces production costs, making the product more in line with market demands.

[0066] In summary, the expandable power strip provided in this embodiment successfully solves long-standing technical problems in the field of expandable sockets, such as low space utilization, inconvenient operation, and poor electrical safety, through a series of innovative designs. This product not only boasts advantages such as simple structure, ease of use, and reliability, but also features excellent expandability and modular design, meeting the needs of different scenarios and providing users with an aesthetically pleasing and practical power solution.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
