Description

Technical Field

[0001] This utility model relates to the field of adapter socket technology, specifically to a compact plug assembly structure with multiple sets of plug specifications. Background Technology

[0002] As people's living standards gradually improve, they have more and more opportunities to travel abroad for tourism or business. Due to the different power socket standards in different countries, electrical plugs come in various shapes and styles. This means that electrical appliances brought out of the country cannot be used with local sockets abroad, causing considerable inconvenience to travelers.

[0003] Therefore, to facilitate people's travel, a type of adapter socket has emerged on the market. These adapters feature different types of prongs for use in different regions and also have panels with multiple types of sockets. To accommodate different standards or specifications, the prong assembly often has multiple sets of prongs arranged side-by-side, allowing it to connect with sockets in different regions after extending out of the socket housing. Currently, because multiple prongs are arranged side-by-side within the housing, the lateral dimension of the prong assembly is relatively large, increasing the overall size of the adapter socket and making it inconvenient for users to carry.

[0004] Therefore, there is an urgent need for a compact pin assembly structure with multiple pin specifications to solve at least one of the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a compact pin assembly structure with multiple pin specifications. To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0006] A compact plug assembly structure with multiple sets of plug specifications includes a bracket assembled inside a socket housing, on which a plug assembly is slidably connected in a vertical direction. The plug assembly includes a first plug unit and a second plug unit arranged side by side.

[0007] The first plug unit includes a first telescopic member and a first linkage member that are arranged side by side in the vertical direction and slidably connected to the bracket. The first telescopic member is provided with a plug for inter-plugging with an external socket, and the first linkage member is provided with a through hole for the plug to extend or retract.

[0008] The second pin unit includes a second telescopic member that is slidably connected to the bracket, and a three-pole pin corresponding to E, L and N is fixedly provided on the second telescopic member;

[0009] The first linkage component has an embedding structure on the side corresponding to the second pin unit, so that the pin in the second pin unit corresponding to the E pole is embedded into the side of the first linkage component.

[0010] Furthermore, the embedded structure includes a sliding groove disposed vertically on the first linkage member, and the pin corresponding to the E pole in the second pin unit is slidably disposed vertically within the sliding groove.

[0011] Furthermore, an embedded structure is provided between the first telescopic member and the first linkage member, so that when the first pin unit is retracted into the bracket, the first telescopic member is at least partially embedded in the first linkage member.

[0012] Furthermore, the embedded structure includes:

[0013] An insert portion formed on the first telescopic member and protruding toward the first linkage member, and a push portion extending toward both ends along the length direction of the first telescopic member, the pins formed on the insert portion, a fastener formed on the side of the first telescopic member, and a horizontal difference between the fastener and the surface of the push portion toward the first linkage member;

[0014] A seat body is formed at one end of the first linkage member, and a side wall is formed along one side edge of the seat body and extends away from the seat body. The end of the seat body facing the first telescopic member is formed with a cavity, which is precisely for the insertion part to extend into, and the through hole is formed at the bottom of the cavity. A linkage groove is formed on the side wall for the locking pin to slide within it.

[0015] Furthermore, the bracket includes an upper frame and a lower frame arranged vertically, and a plurality of guide columns for support are provided between the upper frame and the lower frame. The first pin unit and the second pin unit are slidably connected to the guide columns in the vertical direction.

[0017] Furthermore, the second telescopic member includes two mounting portions arranged side by side, and a clearance space is defined between the two mounting portions for the third pin unit to be placed therein. The pins are respectively fixedly mounted on the mounting portions, and a connecting portion is provided between the two mounting portions for connecting the two mounting portions.

[0018] Furthermore, each of the first, second, and third telescopic members has a lever end that extends out of the bracket.

[0019] Furthermore, the pins respectively disposed on the first pin unit, the second pin unit and the third pin unit are configured with different standard specifications.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a compact plug assembly structure with multiple plug specifications.

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0031] This utility model embodiment provides a compact plug assembly structure with multiple sets of plug specifications, which serves as an important component of a conversion socket. The bracket 200 provides two main plug holes and two auxiliary plug holes located on two adjacent sides. In this embodiment, the main plug holes are provided in multiple sets arranged side by side in one direction, and the multiple sets of main plug holes are configured with different types. Specifically, the main plug holes are configured as at least one type of two-pole plug hole or three-pole plug hole. The auxiliary plug holes are located on the side extending in the side-by-side direction of the main plug holes. Thus, this bracket structure allows for more plugging positions, enabling more electrical appliances to be plugged in when using electrical appliances. Meanwhile, a plug assembly 300 is provided on the bracket 200 for connecting to an external socket, thereby energizing the adapter socket and facilitating the use of electrical devices on the adapter socket. In order to be compatible with external sockets of different regions or different standards, the plug assembly 300 is provided with two parallel and slidably connected first plug unit 310 and second plug unit 330 on the bracket. An embedding structure is provided on the first plug unit 310 and the second plug unit 330, which allows the plug of the second plug unit 330 to be embedded into the first plug unit 310, thereby reducing the lateral dimension of the parallel plug assembly, reducing the overall size of the adapter socket, and making it more convenient to carry.

[0032] In this embodiment, as Figure 1-6As shown in this embodiment of the utility model, a compact plug assembly structure with multiple sets of plug specifications is provided. It includes a bracket 200 assembled within a socket housing 100. A plug assembly 300 is slidably connected to the bracket 200 in a vertical direction. The plug assembly 300 includes a first plug unit 310 and a second plug unit 330 arranged side-by-side. The first plug unit 310 includes a first telescopic member 311 and a first linkage member 320 arranged side-by-side in a vertical direction and slidably connected to the bracket. The first telescopic member 311... The first linkage 320 is provided with a plug 313 for interlocking with an external socket, and a through hole is provided on the first linkage 320 for the plug 313 to extend and retract; the second plug unit 330 includes a second telescopic member 331 slidably connected to the bracket 200, and a three-pole plug corresponding to E, L and N is fixedly provided on the second telescopic member 331; the first linkage 320 and the side of the second plug unit 330 are provided with an embedding structure, so that the plug 313 corresponding to the E pole in the second plug unit is embedded into the side of the first linkage 320.

[0033] In this embodiment, the first plug unit 310 is set as a European standard plug unit, and the second plug unit 330 is defined as a British standard plug. By embedding the E-pole plug 313 of the second plug unit 330 with the first linkage 320 through an embedded structure, the lateral dimensions of the first plug unit 310 and the second plug unit 330 can be shortened, thereby reducing the lateral dimension of the plug assembly 300. This further allows the adapter to have a more compact structure, thereby reducing the size of the adapter and reducing the space occupied in luggage during travel, thus improving portability.

[0034] Furthermore, the embedded structure includes a sliding groove 325 vertically disposed on the first linkage 320, and the pin 313 corresponding to the E pole in the second pin unit 330 is slidably disposed within the sliding groove 325 vertically. During use, the E pole pin 313 is embedded within the sliding groove 325, thereby shortening the lateral dimension of the second pin unit 330 relative to the first pin unit 310. In other words, during installation, the distance between the first pin unit 310 and the second pin unit 330 can be further reduced, thereby reducing the width of the socket. Simultaneously, during the extension or retraction of the first pin unit 310 or the second pin unit 330, the E pole pin 313 and the sliding groove 325 are in a sliding engagement, providing guidance and stability, making the extension of the first pin unit 310 or the second pin unit 330 more stable.

[0035] In this embodiment, as Figure 1 , 5As shown, an embedded structure is also provided between the first telescopic member 311 and the first linkage member 320 of the first pin unit 310, so that when the first pin unit is retracted into the bracket 200, the first telescopic member 311 is at least partially embedded in the first linkage member 320.

[0036] In this embodiment, the embedded structure allows at least a portion of the first telescopic member 311 to be embedded within the first linkage member 320 when the first telescopic member 311 and the first linkage member 320 are retracted inside the bracket 200. This reduces the overall height of the first plug unit 310, ensuring a more compact bracket structure, and consequently, a more compact and smaller adapter plug.

[0037] Specifically, the embedded structure includes an insert portion 316 formed on the first telescopic member 311 and protruding toward the first linkage member 320, and a push portion 317 extending toward both ends along the length of the first telescopic member 311. A pin 313 is formed on the insert portion 316. A latch 318 is formed on the side of the first telescopic member 311. There is a horizontal difference between the latch 318 and the surface of the push portion 314 facing the first linkage member 320. The embedded structure also includes a seat 321 formed at one end of the first linkage member 320 and a side wall 323 formed on one side edge of the seat 321 and extending away from the seat 321. A cavity 322 is formed at the end of the seat 321 facing the first telescopic member 311. The cavity 322 is precisely for the insert portion 316 to extend into, and a through hole for the pin 313 to extend out is provided at the bottom of the cavity 322. A linkage groove 324 is provided on the side wall 323 for the latch 318 to slide within it.

[0038] The first telescopic member 311 of the first pin unit 310 is configured as an insert 316 and a pusher 317, so that when the pin 313 is fixed on the insert 316, the insert 316 has sufficient volume to ensure the installation requirements of the pin 313 and the insulation between them. During the process of pushing out the first pin unit 310, the insert 316 extends into the cavity 322 of the first linkage member 320, and the pusher 317 contacts the end of the seat 321 of the first linkage member 320, thereby pushing out the first linkage member 320. When the first pin unit 310 is retracted into the internal space of the bracket, the first telescopic member 311 is pulled. At this time, the clip 318 slides in the linkage groove 324 and is limited by the top of the sliding groove 325, which drives the first linkage member 320 to retract into the internal space of the bracket. Through the above structure, the structure is more compact when the first plug unit 310 is retracted into the internal space of the bracket 200, thereby ensuring that the height of the socket does not increase.

[0039] In this embodiment, the bracket 200 includes an upper frame 201 and a lower frame 202 arranged vertically. A plurality of guide columns 203 for support are arranged between the upper frame 201 and the lower frame 202. The first pin unit and the second pin unit are slidably connected to the guide columns 203.

[0040] In this embodiment, as Figure 1-4 As shown, at least one third pin unit 340 is provided between the first pin unit 310 and the second pin unit 330, which is parallel to the first pin unit 310. The third pin unit 340 includes a third telescopic member 341 that is slidably connected to the bracket 200 in the vertical direction, and a pin 313 that is fixedly installed on the third telescopic member 341 for interfacing with an external socket.

[0041] In other words, this embodiment features three pin units, which improves the usability of the adapter and allows for better compatibility with external sockets. In this embodiment, the pins 313 on the first pin unit 310, the second pin unit 330, and the third pin unit 340 are configured with different standards. In this embodiment, the pins on the three pin units can be configured with one or more of the following standards: European, Japanese, British, Indian, Australian, and Chinese.

[0042] In this embodiment, to facilitate the movement of the third pin unit 340, such as Figure 4 As shown, the second telescopic member 331 in the second pin unit 330 is designed as follows: the second telescopic member 331 includes two mounting portions 3311 arranged side by side, and a clearance space 3313 is defined between the two mounting portions 331 for the third pin unit 340 to be placed therein. The pins 313 are respectively fixedly mounted on the mounting portions 3311, and a connecting portion 3312 is provided between the two mounting portions 3311 for connecting the two mounting portions 3311.

[0043] In other words, the E-pin 313 of the second pin unit 330 is mounted on the mounting part 3311 corresponding to the first pin unit 310, and the other two pins 313 are mounted on the mounting part 3311 away from the first pin unit 310. The two mounting parts 3311 are fixedly connected by the connecting part 3312 to form a whole, thereby defining a clearance space 3313 between the two mounting parts 3311 to facilitate the installation of the third pin unit 340. Through the above arrangement, the third pin unit 340 can be placed inside the second pin unit 330, further ensuring the compactness of the pin assembly 300 and reducing the overall size of the pin assembly.

[0044] In this embodiment, as Figure 3-4As shown, in order to facilitate the extension or retraction of the three plug-in units on the bracket 200, a toggle end 321 extending from the bracket is formed on the first telescopic member 311, the second telescopic member 331 and the third telescopic member 341.

[0045] like Figure 7 As shown, this is a conversion socket using the bracket structure provided by this utility model. Two socket panels are formed on the socket housing 100. Specifically, there are two adjacent main socket panels and a secondary socket panel, which can provide multiple positions for two electrical appliances to be plugged into the socket at the same time.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
