Description

Technical Field

[0001] The utility model relates to the field of sockets, and in particular to a universal anti-dropping socket for IEC plugs. Background Art

[0002] IEC sockets are designed and manufactured according to the standards set by the International Electrotechnical Commission. Existing IEC sockets are all regulated by international or national standards and are primarily available in two types: 10A and 16A. Choose a different end-point power distribution socket based on the power requirements of your switch and server.

[0003] Standard 10A and 16A sockets have different structures, sizes, and dimensions, making them incompatible. In practice, electromechanical engineers must select different sockets based on the power requirements of switches and servers. Users must configure power distribution according to the configured terminal power distribution system, and each socket requires a specific interface, which increases power distribution costs and inconvenience. Furthermore, existing sockets lack a release mechanism. When the plug and socket are connected for a long period of time, the elastic force of the socket's copper sheet pushes the plug pin outward, causing poor contact or the risk of the plug falling off. Utility Model Content

[0004] In view of this, the utility model provides a universal anti-drop socket which can be used with two different types of IEC plugs and can effectively prevent the plugs from falling off.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A universal anti-dropout socket for an IEC plug comprises: a housing having a cavity and a socket disposed within the cavity, the socket being provided with three jacks distributed in a triangle pattern and three slots respectively connected to the three jacks, current-carrying copper sleeve components being removably inserted into the slots, the current-carrying copper sleeve component comprising a wiring portion and a first conductive portion and a second conductive portion electrically connected to the wiring portion, the jack comprising a vertical socket and a horizontal socket, the first conductive portion and the second conductive portion respectively docking with the vertical socket and the horizontal socket; and an anti-dropout fixing for preventing the plug from falling out is further provided on one end of the housing close to the jack.

[0007] In the above technical solution, three jacks distributed in a triangular shape are arranged on the socket, and each jack has a horizontal socket and a vertical socket. In this way, the three horizontal sockets correspond to one type of plug, and the three vertical sockets correspond to another type of plug, so that the socket can be compatible with two different IEC plugs, simplifying the types and configuration methods of the terminal power sockets, unifying the specifications of the output sockets, simplifying the configuration of the product, reducing the product specifications, and greatly improving the applicability and compatibility of the socket.

[0008] Furthermore, the current-carrying copper sleeve is removable for easy replacement and maintenance. If the sleeve becomes worn or damaged due to long-term use, users only need to replace the sleeve, rather than replacing the entire socket, reducing repair costs. Furthermore, the anti-dropout fixture on the housing effectively prevents the plug from accidentally falling out during use, enhancing the socket's safety and stability. The anti-dropout fixture ensures a tight connection between the plug and socket, especially in vibrating or tilted environments.

[0009] Optionally, in a possible implementation, the first conductive portion includes two first metal springs that are oppositely arranged, a first clamping groove is formed between the two first metal springs, and the first clamping groove is opposite to the vertical socket.

[0010] In the above technical solution, the first clamping groove formed by the two first metal springs can elastically clamp the vertical pins on the plug. When the plug is inserted, the springs will be slightly deformed by pressure, thereby tightly wrapping the pins, ensuring the high efficiency and stability of current transmission and reducing the problem of poor contact.

[0011] Optionally, in a possible implementation, the second conductive portion includes a second metal spring, a second clamping groove is formed between the second metal spring and the first conductive portion, and the second clamping groove is opposite to the horizontal socket.

[0012] In the above technical solution, the second clamping groove formed between the second metal spring and the first conductive portion achieves a perfect fit with the horizontal socket. The elastic action of the spring tightly clamps the pins within the horizontal socket. Furthermore, the cooperation between the second metal spring and the first conductive portion more effectively utilizes the internal space of the socket, making the overall layout of the socket more compact and orderly.

[0013] Optionally, in a possible implementation, the first clamping groove and the second clamping groove are both structures with a gradually changing groove width.

[0014] In the above technical solution, the gradual design of the slot width allows the plug to be gradually guided during the insertion process until it is fully inserted. This not only reduces the friction and resistance of the plug during the insertion process, but also improves the smoothness and convenience of the insertion, allowing users to easily complete the insertion operation.

[0015] Optionally, in a possible implementation, the jack is a "T"-shaped structure, wherein the two jacks located on both sides are in an inverted "T"-shaped structure, and the jack located in the middle is in an upright "T"-shaped structure.

[0016] In the above technical solution, the "T"-shaped jack can be matched with the vertical socket and the horizontal socket respectively. The position distribution of the three "T"-shaped jacks can make it more compact, so as to better adapt to different types of plugs and make it easier for the plug to find the correct plugging direction when inserted.

[0017] Optionally, in a possible implementation, a limiting spring piece is provided on the wiring portion, a limiting hole is provided in the slot, and the limiting spring piece can be snapped into the limiting hole.

[0018] In this technical solution, the retaining spring combines with the retaining hole in the socket to form a stable snap-in mechanism, ensuring that the wire or cable remains firmly connected after being plugged into the socket, and is not easily loosened or removed by external forces, thereby ensuring the stability and reliability of the electrical connection. It also simplifies the installation process; simply push the wiring part into the socket until the retaining spring snaps into the retaining hole.

[0019] Optionally, in a possible implementation, an extension boss is provided on the outer edge of the shell, and the anti-slip fixing member includes two clamping blocks that are relatively and movably arranged on the extension boss, and the clamping blocks can be moved closer to or away from the insertion platform.

[0020] In the above technical solution, the extended boss design provides a stable support platform for the anti-dropout fixture. The movable clamping block on the extended boss enables it to tightly clamp the plug when needed, effectively preventing the plug from loosening or falling out. In addition, by designing two opposing and movable clamping blocks, users can easily adjust them to accommodate plugs of different sizes or shapes.

[0021] Optionally, in a possible implementation, a hook is connected to the block, and a strip-shaped slot is provided on the extension boss, and the hook can be engaged in the strip-shaped slot and can move along the slot.

[0022] In the above technical solution, the hook attached to the card block combines with the strip slot on the extended boss to form a flexible adjustment and positioning mechanism. By moving the hook in the strip slot, the user can easily adjust the relative position between the card block and the plug-in platform to accommodate different types of plugs. In addition, the hook's snap-fit ​​design within the strip slot ensures the stability of the card block during the fixing process. Because the hook is firmly fixed in the slot, the card block is unlikely to loosen or fall off even under external force.

[0023] Optionally, in a possible implementation, the card block is a "U"-shaped structure, and a card plate is provided on the opposite side of the two card blocks.

[0024] In the above technical solution, the card block adopts a "U"-shaped structure design, which can better match the plug. The card plate can resist the card slot on the side of the socket to prevent the socket from moving relative to the socket, thereby ensuring a stable connection between the socket and the socket.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0033] Please refer to Figure 1-Figure 4 The present embodiment provides a universal anti-dropout socket for an IEC plug, comprising: a housing 1 having a cavity 11 and a socket 2 disposed in the cavity 11, wherein the cavity 11 is an open cavity 11 with a top opening, and the socket 2 has an external profile that matches the plug, and is provided with three jacks 3 distributed in a triangular shape, and three slots 4 respectively connected to the three jacks 3, wherein a current-carrying copper sleeve component 5 is detachably inserted into the slot 4, and the current-carrying copper sleeve component 5 includes a wiring portion 51, and a first conductive portion 52 and a second conductive portion 53 electrically connected to the wiring portion 51, the jack 3 includes a vertical socket 31 and a horizontal socket 32, and the first conductive portion 52 and the second conductive portion 53 are respectively connected to the vertical socket 31 and the horizontal socket 32; an anti-dropout fixing member 7 for preventing the plug from falling out is also provided on one end of the housing 1 close to the jack 3.

[0034] In this embodiment, three sockets 3 are arranged in a triangle shape on the socket 2, and each socket 3 has a horizontal socket 32 ​​and a vertical socket 31. In this way, the three horizontal sockets 32 correspond to one type of plug, such as a C20 plug, and the three vertical sockets 31 correspond to another type of plug, such as a C14 plug. This makes the socket compatible with two different IEC plugs, simplifies the socket types and configuration methods of the terminal power supply, unifies the specifications of the output sockets, simplifies the product configuration, reduces the product specifications, and greatly improves the applicability and compatibility of the socket.

[0035] Furthermore, the current-carrying copper sleeve 5 is removable, making it easy to replace and maintain. If the sleeve becomes worn or damaged due to long-term use, users only need to replace the sleeve, rather than replacing the entire socket, reducing maintenance costs. Furthermore, the anti-dropout fixture 7 provided on the housing 1 effectively prevents the plug from accidentally falling out during use, enhancing the socket's safety and stability. This fixture ensures a tight connection between the plug and socket, particularly in environments with vibration or tilt.

[0036] It should be noted that the current-carrying copper sleeve component 5 is made of phosphor bronze, which has the advantages of lower temperature rise and higher safety.

[0037] Please refer to Figure 4 In this embodiment, the first conductive portion 52 includes two opposed first metal springs 521. A first clamping groove 54 is formed between the two first metal springs 521. The first clamping groove 54 faces the vertical socket 31. The first metal springs 521 are a multi-section, integrally formed structure. The first clamping groove 54 is used to clamp the plug pins to achieve power supply.

[0038] The first clamping groove 54 formed by two first metal springs 521 elastically grips the vertical pins on the plug, ensuring close contact between the pins and the conductive portion while also tolerating minor variations in pin size, improving the socket's compatibility and adaptability. When the plug is inserted, the springs deform slightly under pressure, tightly wrapping around the pins. This ensures efficient and stable current transmission and reduces the risk of poor contact.

[0039] Please continue to refer to Figure 4 In this embodiment, the second conductive portion 53 includes a second metal spring 531. A second clamping groove 55 is formed between the second metal spring 531 and the first conductive portion 52. The second clamping groove 55 is opposite the horizontal socket 32. Specifically, the second metal spring 531 has the same shape as the first metal spring 521 and is located below the first clamping groove 54 formed by the two first metal springs 521. The second metal spring 531 and the first metal spring 521 are perpendicular to each other, that is, the second metal spring 531 and the two first metal springs 521 jointly form the second clamping groove 55.

[0040] The second clamping groove 55 formed between the second metal spring 531 and the first conductive portion 52 ensures a good fit with the horizontal socket 32. The elastic action of the spring tightly clamps the pins within the horizontal socket 32. Furthermore, the cooperation between the second metal spring 531 and the first conductive portion 52 allows for more efficient use of the internal space of the slot 4, making the overall layout of the jack 3 more compact and organized.

[0041] In this embodiment, both the first and second clamping grooves 54, 55 have a gradually varying width. Specifically, starting from the jack 3 and extending into the interior of the socket 2, the first and second clamping grooves 54, 55 gradually narrow and then widen, narrowing at both ends toward the center. This creates a bell-shaped shape near the jack 3, providing a guide for facilitating insertion of the plug pins, while the narrower center portion secures the pins.

[0042] Therefore, in this embodiment, the plug can be gradually guided during the insertion process until it is fully inserted through the design of the gradual change in the slot width. This not only reduces the friction and resistance of the plug during the plugging process, but also improves the smoothness and convenience of the plugging, allowing users to easily complete the plugging operation.

[0043] Please refer to Figure 1 In this embodiment, the jack 3 has a "T"-shaped structure, with the two jacks 3 on either side forming an inverted "T" structure, and the jack 3 in the middle forming an upright "T" structure. The "T"-shaped jack 3 can be matched with the vertical socket 31 and the horizontal socket 32, respectively. The distribution of the three "T"-shaped jacks 3 makes it more compact, allowing for better adaptation to different types of plugs and making it easier for the plug to find the correct insertion direction when inserted.

[0044] Please refer to Figure 2 and Figure 3 In this embodiment, a retaining spring 511 is provided on the wiring portion 51, and a retaining hole 41 is provided in the slot 4. The retaining spring 511 can be snapped into the retaining hole 41. The retaining spring 511 combines with the retaining hole 41 in the slot 4 to form a stable snap-fit ​​mechanism, ensuring that the wire or cable remains firmly connected after being plugged into the socket, and is not easily loosened or disconnected due to external forces, thereby ensuring the stability and reliability of the electrical connection. It also simplifies the installation process; simply push the wiring portion 51 into the slot 4 until the retaining spring 511 snaps into the retaining hole 41.

[0045] Please refer to Figure 1 In this embodiment, an extension boss 6 is provided on the outer edge of the housing 1. The anti-dropout fixing member 7 includes two opposing and movably disposed blocks 71 on the extension boss 6. The blocks 71 can move closer to or further away from the insertion platform 2. The extension boss 6 is located at the outer edge of the top opening of the cavity 11.

[0046] The design of the extended boss 6 provides a stable support platform for the anti-dropout fixture 7. The movable clamping block 71 on the extended boss 6 enables it to tightly clamp the plug plugged into the socket 2 when needed, effectively preventing the plug from loosening or falling out. In addition, the design of two opposing and movable clamping blocks 71 allows users to easily adjust them to accommodate plugs of different sizes or shapes.

[0047] Please refer to Figure 3Specifically, a hook 711 is connected to the clamping block 71, and a strip-shaped clamping groove 61 is provided on the extended boss 6. The hook 711 can be clamped into the strip-shaped clamping groove 61 and can move along the clamping groove. The two clamping blocks 71 arranged opposite to each other are both provided with a hook 711, and each hook corresponds to a strip-shaped clamping groove 61, so that the hook can move within the corresponding strip-shaped clamping groove 61. Of course, as another embodiment, the strip-shaped clamping groove 61 can also be provided as one, and the hooks 711 on the two clamping blocks 71 can move within the same strip-shaped clamping groove 61. In addition, it should be noted that the hook 711 has a certain degree of elasticity, and it can be clamped close to the strip-shaped clamping groove 61 by squeezing.

[0048] This embodiment combines the hook 711 connected to the block 71 with the strip-shaped slot 61 on the extended boss 6 to form a flexible adjustment and positioning mechanism. By moving the hook 711 within the strip-shaped slot 61, the user can easily adjust the relative position between the block 71 and the socket 2 to accommodate different types of plugs. Furthermore, the snap-fit ​​design of the hook 711 within the strip-shaped slot 61 ensures the stability of the block 71 during the fixing process. Because the hook 711 is securely fixed in the slot, the block 71 is unlikely to loosen or fall off, even under external force.

[0049] In this embodiment, the card block 71 has a "U"-shaped structure, and a card plate is provided on the opposite side of the two card blocks 71. The "U"-shaped structure design of the card block 71 can better match the plug. The card plate can resist the card slot or step on the side of the socket. For example, when the plug is a C14 plug, the card plate can be stuck on the step of the C14 plug. When the plug is a C20 plug, the card plate can be stuck in the C14 card slot. This can prevent the socket from moving relative to each other, thereby ensuring a stable connection between the socket and the socket 2. Specifically, the hooks 711 on the same card block 71 can be two oppositely arranged, and correspondingly, the bar-shaped card slots 61 can also be two corresponding ones. This can further improve the fixing stability of the card block 71. This arrangement enables the card block 71 to provide a locking force of not less than 200N.
