Description

Technical Field

[0001] This application relates to the technical field of adapter sockets, and more particularly to an adapter socket. Background Technology

[0002] A power adapter is a common electrical device used to convert one power plug standard to another or to expand the number of power outlets to meet the power supply needs of different electronic devices. With the increasing prevalence and diversity of electronic devices, power adapters are being used more and more widely in homes, offices, and while traveling.

[0003] Traditional adapters typically feature a one-piece design with a complex internal structure, making disassembly and maintenance difficult. When a socket or component malfunctions, the entire adapter often needs to be replaced, increasing costs and inconvenience. Therefore, most adapters today are modular. Modular adapters usually consist of a housing and a base cover. The housing contains multiple modular socket units, allowing users to replace or maintain specific socket units as needed without replacing the entire adapter.

[0004] However, when users maintain a modular socket unit, they often need to remove the housing of the modular socket unit. Since the modular socket unit is often a fixed one-piece connection, it is difficult to disassemble and maintain, resulting in low maintenance efficiency of the modular socket unit. Utility Model Content

[0005] To facilitate the installation and removal of the adapter during maintenance, an adapter is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A converter socket includes a housing and a snap-fit ​​bottom cover. A circuit board assembly is fixed on the bottom cover, and at least two socket assemblies are mounted on the circuit board assembly. Each socket assembly includes two opposing parallel first side frames and second side frames. A middle frame is further provided between the first and second side frames, and a connecting piece is installed within the middle frame. The connecting piece passes through the socket assembly and connects to the circuit board assembly. A buckle is fixed on the first side frame, and a locking block is fixed on the second side frame. The first and second side frames are interlocked by the buckle and the locking block.

[0008] By adopting the above technical solution, the snap-fit ​​and snap-block structural design makes the socket assembly easier to assemble. Users can quickly disassemble and assemble the socket assembly without complicated tools or steps. When it is necessary to maintain or replace a socket unit, users can easily separate the relevant parts for targeted repair or replacement without disassembling the entire socket structure, thereby improving maintenance efficiency.

[0009] Optionally, the number of buckles and blocks is at least three, with the three buckles located on both sides of the top of the first side frame and the bottom of the first side frame, and the three blocks located on both sides of the top of the second side frame and the bottom of the second side frame.

[0010] By adopting the above technical solution, the distribution of multiple buckles makes the connection between the first side frame and the second side frame more uniform, avoiding deformation or damage caused by excessive force at a certain point. The combined use of multiple buckles can also effectively prevent loosening caused by vibration or insertion and removal operations.

[0011] Optionally, the housing is provided with a front insertion surface and two side insertion surfaces. At least two sets of reinforcing ribs are fixed on the inner walls of the two side insertion surfaces. There are two reinforcing ribs in the same set, and they are located on both sides of a socket assembly.

[0012] By adopting the above technical solution, the socket assembly is located between adjacent reinforcing ribs, which can ensure that the main frame socket is more stable in the housing, avoid socket displacement or loosening caused by housing deformation or external force, and effectively reduce the displacement of the socket assembly caused by vibration or plugging and unplugging operations during use, thereby improving the installation stability of the socket.

[0013] Optionally, two limiting seats are fixed on the inner walls of the bottom of the two side insertion surfaces, and two limiting buckles are fixed on both sides of the bottom cover, with the two limiting seats engaging with the two limiting buckles respectively.

[0014] By adopting the above technical solution and replacing the traditional screw connection with a limit buckle connection, users can easily complete the installation and disassembly of the shell and bottom cover without the need for tools, making the operation more convenient. At the same time, it can effectively disperse the stress under vibration or external force, reduce the loosening problem caused by vibration or impact during the use of the equipment, and improve the seismic performance of the overall structure.

[0015] Optionally, the circuit board assembly is fixed with a USB plug and a Type-C plug, and the front plug surface has a USB port and a Type-C port, and the USB plug and the Type-C plug are respectively connected to the USB port and the Type-C port.

[0016] By adopting the above technical solution, users can plug and unplug using a USB cable when they do not have a plug with them, which improves both applicability and user experience.

[0017] Optionally, the outer wall of the housing has a plug interface corresponding to the socket assembly, and the housing has a movable groove. A limiting member is installed in the movable groove. The limiting member includes a connecting part. The limiting part is fixed on the side of the connecting part facing the plug interface and is located inside the plug interface. An adjusting part is fixed at the other end of the connecting part and extends through the housing.

[0018] By adopting the above technical solution, when the plug is inserted into the socket assembly through the plug interface, the limiting part is located on one side of the plug interface. The limiting part does not limit the plug. After the adjustment part is pushed, the adjustment part pushes the limiting part towards the plug interface through the connecting part. Then the limiting part will engage with the plug, limiting the plug in the plug interface and preventing the plug from being pulled out of the plug interface. This can effectively prevent the plug from accidentally loosening or slipping during use, and allows users to easily limit and fix the plug, thereby improving the convenience and safety of the adapter socket.

[0019] Optionally, the end of the limiting portion is provided with a chamfer.

[0020] By adopting the above technical solution, the chamfer design reduces the friction between the insert and the limiting part, allowing the insert to engage more smoothly with the limiting part, thereby improving the user experience and the service life of the equipment.

[0021] Optionally, limiting protrusions are fixed on both opposite sides of the limiting portion.

[0022] By adopting the above technical solution, the limiting protrusion increases the force of the limiting part against the plug, further enhancing the fixing effect of the limiting part on the plug, thereby improving the reliability and safety of the adapter.

[0023] Optionally, a push button is installed on the end of the adjustment part that extends outside the housing, and the push button abuts against the outer surface of the housing.

[0024] By adopting the above technical solution, users can easily adjust the position of the limiting part by pushing the button, thereby changing the state between the limiting part and the insert. At the same time, when the housing and socket assembly are being maintained, pushing the button provides support for the limiting part, preventing the limiting part from falling out of the housing during maintenance.

[0025] In summary, this application has at least the following beneficial effects:

[0026] 1. The design of the snap-fit ​​and locking mechanism makes the assembly and disassembly of the socket assembly easier, allowing users to quickly maintain or replace it without disassembling the entire socket structure, thus improving maintenance efficiency.

[0027] 2. The design of the limiting component can effectively prevent the insert from accidentally loosening or slipping during use, improving ease of use and safety. Attached image description:

[0037] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0038] Example 1

[0039] As attached Figure 1 and attached Figure 2 As shown, a converter socket includes a housing 1 and a bottom cover 2 that engages with it.

[0040] The housing 1 is trapezoidal in shape. The housing 1 is provided with a front plug-in surface 11 and two side plug-in surfaces 12. Two sets of plug-in interfaces 13 that penetrate the housing 1 are respectively opened on the front plug-in surface 11 and the two side plug-in surfaces 12. The front plug-in surface 11 is also provided with a USB port 14 and two Type-C ports 15.

[0041] Limiting seats 16 are fixed on the bottom inner walls of the two side insertion surfaces 12, and insertion blocks 17 are fixed around the bottom inner wall of the housing 1. The insertion blocks 17 have a fixing groove 171 on the side facing the bottom cover 2.

[0042] Two limit buckles 21 are fixed on the side of the bottom cover 2 facing the housing 1. They are located on the side of the two side insertion surfaces 12 facing the bottom cover 2, and the two limit buckles 21 are respectively engaged with two limit seats 16 to connect the housing 1 and the bottom cover 2. The connection of the limit buckles 21 replaces the traditional screw connection, and the user can easily complete the installation and disassembly of the housing 1 and the bottom cover 2 without the use of tools, making the operation more convenient.

[0043] The bottom cover 2 is also fixed with eight fixing blocks 22 on the side facing the housing 1. The eight fixing blocks 22 are located around the bottom cover 2, and the fixing blocks 22 are inserted into the fixing grooves 171 on the plug 17. The insertion of the plug 17 into the fixing grooves 171 is used to limit the housing 1 and reduce the loosening problem caused by the use of the adapter in a vibration environment.

[0044] A circuit board assembly 3 is also installed on the side of the bottom cover 2 facing the housing 1. The circuit board assembly 3 is located inside the housing 1. A USB plug 31 and a Type-C plug 32 are fixed on the circuit board assembly 3. The USB plug 31 and the Type-C plug 32 are respectively connected to the USB port 14 and the Type-C port 15. When the user does not have a plug, he / she can use the USB port 14 or the Type-C port 15 to charge, which improves the applicability and the user experience.

[0045] As attached Figure 1 and attached Figure 3 As shown, two socket assemblies 4 are also fixed on the circuit board assembly 3. The two socket assemblies 4 are parallel to each other and are trapezoidal in shape. The socket assembly 4 is provided with a front insertion part 41 and two side insertion parts 42. The two side insertion parts 42 and the front insertion part 41 are respectively provided with slots 43. The side insertion parts 42 and the front insertion parts 41 of the two socket assemblies 4 abut against the side insertion surface 12 and the front insertion surface 11 of the housing 1, respectively, and the slots 43 are connected to the insertion interface 13.

[0046] As attached Figure 4 and attached Figure 5As shown, the socket assembly 4 includes two relatively parallel first side frames 44 and second side frames 45. A middle frame 46 is also provided between the first side frame 44 and the second side frame 45. A connecting piece 47 is installed in the middle frame 46. There are three connecting pieces 47. Each of the three connecting pieces 47 is provided with three terminals 471, which are located in the slots 43 of the side plug-in surface 12 and the front plug-in surface 11, respectively. The bottom of the connecting piece 47 passes through the socket assembly 4 and is connected to the circuit board assembly 3.

[0047] Three clips 441 are fixed on the first side frame 44. The three clips 441 are located on both sides of the top of the first side frame 44 and the bottom of the first side frame 44, respectively. Three latches 451 are fixed on the second side frame 45. The three latches 451 are located on both sides of the top of the second side frame 45 and the bottom of the second side frame 45, respectively. The first side frame 44 and the second side frame 45 are connected to each other by the clips 441 and the latches 451, which makes the assembly of the socket assembly 4 easier and allows for quick separation of related parts for targeted repair or replacement, thereby improving maintenance efficiency.

[0048] As attached Figure 2 As shown, two sets of reinforcing ribs 18 are also fixed on the housing 1. The two sets of reinforcing ribs 18 are located on the inner walls of the two side insertion surfaces 12 respectively. The two sets of reinforcing ribs 18 are parallel to each other. There are two reinforcing ribs 18 in the same set, and they are located on both sides of a socket assembly 4 respectively. They are used to limit the socket assembly 4. At the same time, when the housing 1 and the bottom cover 2 are fastened together, the reinforcing ribs 18 guide and limit the socket assembly 4, which can ensure that the position of the socket assembly 4 in the housing 1 is more stable and avoid the socket from shifting or loosening due to the deformation of the housing 1 or the action of external force.

[0049] Example 2

[0050] This second embodiment is a further improvement on the shell 1 based on the first embodiment. The other structures are the same as those in the first embodiment, and will not be described in detail here.

[0051] As attached Figure 6 and attached Figure 7 As shown, the housing 1 also has a movable groove 19, and a limiting member 5 is installed in the movable groove 19. There are six limiting members 5, and the six limiting members 5 are located on one side of the six sets of plug interfaces 13.

[0052] As attached Figure 7 and attached Figure 8As shown, the limiting member 5 includes a connecting part 51, an adjusting part 52, and a limiting part 53. The connecting part 51 is located in the movable groove 19. A limiting part 53 is provided on the side of the connecting part 51 facing the insertion interface 13. There are two sets of limiting parts 53. The two sets of limiting parts 53 are located in the two insertion interfaces 13 of the same group, and the ends are provided with chamfers. Limiting protrusions 531 are fixed on the opposite sides of the two limiting parts 53 of the same group.

[0053] An adjustment part 52 is provided on the side of the connecting part 51 facing away from the insertion interface 13. One end of the adjustment part 52 is fixedly connected to the connecting part 51, and the other end extends through the outer side of the housing 1. A push button 521 is fixed on the end. The push button 521 abuts against the outer surface of the housing 1, so that the user can adjust the position of the limiting part 53 by pushing the button 521, thereby changing the state between the limiting part 53 and the insert.

[0054] When the plug is inserted into the socket assembly 4 through the plug interface 13, the limiting part 53 is located on one side of the plug interface 13. The limiting part 53 does not limit the plug. After pushing the push button 521, the adjustment part 52 pushes the limiting part 53 toward the plug interface 13 through the connecting part 51. Then, the limiting protrusion 531 on the limiting part 53 will engage with the plug, limiting the plug in the plug interface 13 and preventing the plug from being pulled out of the plug interface 13. This can effectively prevent the plug from accidentally loosening or slipping during use, and allows users to easily limit and fix the plug, thereby improving the convenience and safety of the adapter.

[0055] Working principle

[0056] When maintenance of the adapter socket is required, first separate the housing 1 from the bottom cover 2, disengage the limit buckle 21 from the limit seat 16, and then disengage the buckle 441 from the locking block 451 on the socket assembly 4. Without the use of other tools, the socket assembly 4 can be quickly separated for targeted repair or replacement. As a result, the housing 1, bottom cover 2, and socket assembly 4 can all be disassembled and maintained more quickly, improving the maintenance efficiency of the adapter socket.

[0057] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
