Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, specifically to a conversion socket. Background Technology
[0002] When a multi-socket adapter is used with a wall socket, to reduce the risk of loosening or detachment due to external force during insertion or cable dragging, which could affect power supply stability, a fixing foot is usually designed to enhance the fixation by inserting it into the wall socket's mounting hole or another unused socket. Later, as wall socket sizes became more diverse, adapters with sliding fixing feet appeared on the market to accommodate different wall socket sizes.
[0003] However, such adapter sockets lack a positioning mechanism during sliding, making it difficult for users to accurately align with the wall socket fixing holes (installation holes or another set of unused sockets), requiring repeated attempts and resulting in a poor user experience. Furthermore, the sliding structure relies solely on friction to maintain its position after adjustment, making it susceptible to displacement due to vibration or insertion / removal forces, leading to poor contact between the socket and the wall socket, and even posing safety hazards. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.
[0036] When a multi-socket adapter (or extension adapter) is used with a wall socket, to reduce the risk of loosening or detachment due to external force during insertion or cable dragging, which could affect power supply stability, it is usually designed with a fixing foot (or dummy foot) that allows it to be inserted through the mounting hole of the wall socket or another unused socket to enhance the fixing effect. With the diversification of wall socket specifications (such as US standard sockets, non-standard GFCI sockets, etc.), adapters with sliding fixing feet have appeared on the market to adapt to different wall socket specifications.
[0037] However, such adapter sockets have the following problems:
[0038] 1. Difficulty in positioning and alignment: Taking US standard sockets as an example, safety standards require multi-outlet extension adapters (such as 3AC and above) to prevent overloading through additional structures (such as fixed feet blocking unused sockets) or overload protection functions. However, existing designs, in order to accommodate standard sockets with different socket spacing and non-standard GFCI sockets, require manual sliding adjustment of the fixed feet. During the adjustment process, there is a lack of positioning mechanism, making it difficult for users to accurately grasp the position of the fixed feet to align with another set of unused sockets. This requires repeated attempts and results in a poor user experience.
[0039] 2. Insufficient structural stability: The sliding structure relies solely on friction to maintain its position, making it susceptible to displacement due to vibration or insertion / removal forces. This can lead to poor contact between the socket and the wall socket, and even pose a safety hazard.
[0040] In summary, existing adapter sockets still need to be optimized in terms of compatibility, fixation reliability, and user experience. There is an urgent need to improve the positioning mechanism and stability of the fixing feet to meet the safety and functional requirements of different wall socket specifications (including standard and non-standard).
[0041] To address these issues, this application presents a new adapter socket designed to solve the aforementioned technical problems. The adapter socket will be described in detail below.
[0042] Firstly, please refer to Figures 1 to 6 The present invention provides a conversion socket, including a cover plate 1, conductive pins 4, fixing pins 2, a circuit board and a housing 5; the cover plate 1 is provided with a receiving groove 11, and the receiving groove 11 is provided with a first through groove 12; the conductive pins 4 protrude from the cover plate 1.
[0043] The fixing pin 2 includes a mounting part 21 and a pin part 22. The mounting part 21 is disposed in the receiving groove 11, and the pin part 22 protrudes from the mounting part 21 and extends out of the cover plate 1 from the first through groove 12.
[0044] The mounting part 21 has a first positioning member 211 on at least one side, and the inner peripheral wall of the receiving groove 11 has a second positioning member 111 on the side opposite to the first positioning member 211, and the second positioning member 111 matches the first positioning member 211.
[0045] In some embodiments, the number of first positioning elements 211 is greater than the number of second positioning elements 111, and the fixing pin 2 is configured to adjust its position by matching different first positioning elements 211 with the second positioning elements 111.
[0046] In other embodiments, the number of the first positioning members 211 is less than the number of the second positioning members 111, and the fixing pin 2 is configured to adjust its position according to the matching of the first positioning member 211 with different second positioning members 111.
[0047] Specifically, the cover plate 1 is provided with a receiving groove 11, and a movable mounting part 21 is installed in the receiving groove 11. The mounting part 21 is provided with a pin part 22, so that the pin part 22 moves with the movement of the mounting part 21, thereby changing the position of the pin part 22 to adapt to different sized sockets. The shape of the receiving groove 11 can be rectangular or other shapes, but it usually has at least two parallel sides to facilitate mating with the mounting part 21 installed therein. In addition, since the second positioning member 111 matches the first positioning member 211, the fixing pin 2 can be positioned during the adjustment of the position of the fixing pin 2, preventing the fixing pin 2 from moving arbitrarily.
[0048] When the number of first positioning members 211 is greater than the number of second positioning members 111, the fixing pin 2 is configured to adjust its position according to the different matching of the first positioning members 211 and the second positioning members 111. At this time, when the first positioning member 211 is moved, at least a portion of the first positioning member 211 is located within the positioning space formed by the second positioning members 111, or at least a portion of the second positioning member 111 is located within the positioning space formed by the first positioning members 211. The set distance between the first positioning member 211 and the second positioning member 111 controls the moving distance of the first positioning member 211, so that the distance adjustment of the fixing pin 2 is controllable. At the same time, since the second positioning member 111 locks / limits the first positioning member 211 after adjusting to the set position, the stability of the first positioning member 211 can be improved, thereby improving the stability of the mounting part 21 and the fixing pin 2.
[0049] When the number of first positioning elements 211 is less than the number of second positioning elements 111, the fixing pin 2 is configured to adjust its position according to the matching of the first positioning element 211 with different second positioning elements 111. At this time, when the first positioning element 211 is moved, the first positioning element 211 is located in the positioning space composed of multiple second positioning elements 111. The set distance between the first positioning element 211 and the second positioning elements 111 is used to control the moving distance of the first positioning element 211, so that the distance adjustment of the fixing pin 2 is controllable.
[0050] In some embodiments, the first positioning member 211 and the second positioning member 111 can be a protrusion and a groove that cooperate with each other. That is, the first positioning member 211 is a protrusion and the second positioning member 111 is a groove; or, the first positioning member 211 is a groove and the second positioning member 111 is a protrusion.
[0051] Furthermore, when the number of first positioning elements 211 is greater than the number of second positioning elements 111, the specific number of first positioning elements 211 can be determined based on the number of wall sockets with different socket spacings that the adapter socket needs to be compatible with. For example, if it needs to be compatible with three types of wall sockets, and the spacing between adjacent sets of sockets for these three types of wall sockets is A, B, and C respectively, then the number of first positioning elements 211 is set to 3. When the number of first positioning elements 211 is less than the number of second positioning elements 111, the number of first positioning elements 211 is similarly determined based on the number of wall sockets with different socket spacings that the adapter socket needs to be compatible with.
[0052] Preferably, when the number of first positioning elements 211 is greater than the number of second positioning elements 111, the number of second positioning elements 111 is 1; when the number of first positioning elements 211 is less than the number of second positioning elements 111, the number of first positioning elements 211 is 1.
[0053] It should be noted that the prong part 22 is a dummy prong, which is usually made of a non-conductive material and does not serve as an electrical connection. For example, the dummy prong is made of PC (polycarbonate) and PP (polypropylene). Furthermore, to address the issue that the distance between the two sockets of a non-standard two-port wall socket differs from that of a standard two-port wall socket, the mounting part 21 is provided with a dummy prong part 22. This allows the power strip to accommodate various socket distances, and when the prong part 22 is moved, it is easier to slide it into position to the required distance from the conductive pin 4 (the power connection terminal).
[0054] For some implementation methods, please refer to Figures 2 to 4 The first positioning member 211 is configured to engage with the second positioning member 111 to provide positioning for the first positioning member 211 and prevent the first positioning member 211 from easily shifting. The engagement form between the first positioning member 211 and the second positioning member 111 can be varied. Typically, the first positioning member 211 and the second positioning member 111 have a wavy or toothed structure to facilitate the first positioning member 211 being moved and locked in place by appropriate force.
[0055] The first positioning member 211 is disposed on the mounting part 21 along the moving direction of the fixing pin 2. It can be understood that the first positioning member 211 and the fixing pin 2 move with the movement of the mounting part 21. During the movement of the fixing pin 2, the first positioning member 211 cooperates with the second positioning member 111 to control the moving distance of the first positioning member 211. The moving direction of the fixing pin 2 is a first direction, and the first positioning member 211 is disposed along this first direction, allowing the amount of movement of the first positioning member 211 to be adjusted by the second positioning member 111 during its movement. In one example, to facilitate accurate adjustment of the position of the mounting part 21, the first positioning member 211 is configured as a male buckle, and the second positioning member 111 is configured as a female buckle. A male buckle and a female buckle are provided between the mounting part 21 and the receiving groove 11. The male buckle can be disposed on the mounting part 21, and the female buckle on the inner wall of the receiving groove 11; alternatively, the female buckle can be disposed on the mounting part 21, and the male buckle on the inner wall of the receiving groove 11. This arrangement allows the mounting part 21 to move within the receiving groove 11, enabling the male and female fasteners to engage. Both sides of the mounting part 21 and the receiving groove 11 are equipped with male and female fasteners, arranged in two sets symmetrically on both sides of the mounting part 21 to facilitate its movement and positioning. The set distance is based on the spacing between the multiple male or female fasteners; it can be equidistant or unequal. After movement, the female and male fasteners of the mounting part 21 engage, forming a stable structure that is not easily loosened, and the position of the mounting part 21 is not easily changed, resulting in more accurate sliding of the mounting part 21.
[0056] In some embodiments, the mounting portion 21 is provided with a second through groove 212, which is configured to deform the first positioning member 211 when the fixing pin 2 is adjusted. It is understood that the second through groove 212 on the mounting portion 21 allows the mounting portion 21 to deform, enabling relative movement between the first positioning member 211 and the second positioning member 111, and providing positioning. Specifically, the second through groove 212 is elongated and arranged along the moving direction of the mounting portion 21. To facilitate deformation of the mounting portion 21, the second through groove 212 is positioned close to the first positioning member 211. There are two first positioning members 211, located on both sides of the mounting portion 21, with second through grooves 212 respectively positioned near the two first positioning members 211, symmetrically arranged on both sides of the mounting portion 21. The second through groove 212 penetrates the main body supporting it. This arrangement allows the second through groove 212 to deform when the main body is compressed, thereby creating a space for the first positioning member 211 to move. The mounting part 21 with the second through groove 212 and / or the cover plate 1 with the first through groove 12 are made of materials that have a certain ability to deform and return to their original shape. They are usually made of insulating plastic materials, such as polycarbonate, ABS, nylon, etc.
[0057] In some implementations, please refer to Figure 1 and Figure 2 It also includes a limiting plate 3, which covers the receiving groove 11 and forms a receiving cavity, and the mounting part 21 is movably disposed in the receiving cavity. It can be understood that the receiving groove 11 and the limiting plate 3 form a receiving cavity, and the mounting part 21 can move within the receiving cavity. The limiting plate 3 covers the receiving groove 11, thus confining the mounting part 21 within the receiving groove 11.
[0058] In some embodiments, the limiting plate 3 is provided with first fixing parts 32 on opposite sides, and the inner peripheral wall of the receiving groove 11 is provided with second fixing parts 112 that match the first fixing parts 32 on opposite sides, so as to fix the limiting plate 3. It can be understood that the limiting plate 3 is rectangular, and the first fixing parts 32 are provided on opposite sides of the limiting plate 3. The first fixing parts 32 and the second fixing parts 112 cooperate to form a fastening installation structure for the limiting plate 3. The second fixing parts 112 are usually provided on opposite sides of the inner peripheral wall of the receiving groove 11 where the second positioning member 111 is not provided, so as to provide a larger installation space. For example, if the second positioning member 111 is provided on the left and right sides of the inner peripheral wall of the receiving groove 11, then the second fixing parts 112 are provided on the upper and lower sides of the inner peripheral wall of the receiving groove 11. For example, the first fixing part 32 is a protruding structure, and the second fixing part 112 is a groove or through hole structure. The protruding structure and the groove or through hole structure are positioned corresponding to each other. When the protruding structure is installed in the groove or through hole structure, a fastening connection is formed.
[0059] Furthermore, the limiting plate 3 matches the shape of the receiving groove 11 and is approximately the same area as the receiving groove 11. The limiting plate 3 covers the receiving groove 11 by a snap-fit method, thereby allowing the mounting part 21 provided in the receiving groove 11 to move in the receiving groove 11 in a restricted direction.
[0060] In some implementations, please refer to Figure 4 and Figure 5 The mounting portion 21 is provided with a first sliding component 213, and the limiting plate 3 is provided with a second sliding component 31 on the side opposite to the mounting portion 21, which matches the first sliding component 213. The mounting portion 21 is slidably connected to the limiting plate 3. It can be understood that the first sliding component 213 and the second sliding component 31 cooperate to reduce the frictional force when the mounting portion 21 is adjusted in position. The second sliding component 31 can be a groove, and the first sliding component 213, which contacts the slide rail, can be a slider, protrusion, or ridge with a length less than the groove; or, the first sliding component 31 can be a groove, and the second sliding component 31 can be a slider, protrusion, or ridge with a length less than the groove.
[0061] In some embodiments, a limiting part 214 is protruding from the side of the mounting part 21 opposite to the limiting plate 3, and the limiting part 214 is movably limited between the first through grooves 12. It is understood that the limiting part 214 and the insertion part 22 are disposed on the same side, and the limiting part 214 is at least partially located within the first through groove 12, so that when the limiting part 214 moves, the groove wall of the first through groove 12 blocks the limiting part 214. The first through groove 12 is rectangular, and the limiting part 214 is also rectangular; the width of the limiting part 214 and the width of the first through groove 12 can be the same.
[0062] In some embodiments, the adapter socket includes a housing 5 and a circuit board, wherein the housing 5 and the cover plate 1 are connected to form a mounting cavity, and the circuit board is disposed in the mounting cavity. It is understood that the circuit board distributes the input power lines (live wire, neutral wire, and ground wire) to each socket, and / or integrates a USB charging port, switch, indicator light, timer, and WiFi module. The circuit board is installed inside the adapter socket for distributing power and integrating various control / conversion functions. The housing 5 and the cover plate 1 are connected to form a mounting cavity for installing electrical components, and the housing 5 and the cover plate 1 are used to protect the electrical components and also to protect the user's safety.
[0063] Therefore, the advantages of the adapter socket in the above technical solution include: 1. Improved stability: Through the multi-positioning design (the first positioning element 211 and the second positioning element 111 cooperate), the fixed plug pin 2 can be firmly locked after adjustment, avoiding the displacement problem caused by the lack of a fixed position in traditional sliding sockets, and significantly enhancing the connection stability between the socket and the wall socket; 2. Strong adaptability: Standardized design for common wall socket specifications on the market, with preset positions based on the spacing of different wall socket holes, users only need to move the fixed plug pin 2 to the corresponding position to match different wall sockets, without repeated fine-tuning, making operation simple and highly universal; 3. Reliable structure: The matching structure of the positioning element, while ensuring adjustment flexibility, effectively prevents the fixed plug pin 2 from accidentally shifting due to external force.
[0064] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
