[0043] The utility model provides an adapter for plugging into a socket having a first surface and provided with at least two socket groups.
[0044] Please refer to Figures 1 to 4 The adapter 100 of one embodiment of the present application includes a shell 10, a circuit board 20, a pin assembly 30 and a charging interface 40. The shell 10 includes a second surface 11 and a third surface 12 arranged adjacent to each other; the circuit board 20 is arranged in the shell 10.
[0045] Among them, the shell 10 serves as the main frame of the adapter 100, which is used to integrate the various components of the adapter 100, such as the circuit board 20, etc., to integrate the various components of the adapter 100 into a whole, and the shell 10 can protect the various components of the adapter 100 and prevent the components from being collided by external forces.
[0046] The pin assembly 30 is provided on the second surface 11 , one end of the pin assembly 30 is electrically connected to the circuit board 20 , and the other end of the pin assembly 30 is exposed outside the second surface 11 . The pin assembly 30 is used to mate with one group of the socket groups 202 of the socket 200 , and the second surface 11 is used to cover the remaining socket groups 202 of the socket 200 .
[0047] In this embodiment, when the adapter 100 is plugged into the socket 200, the second surface 11 of the adapter 100 is aligned with the first surface 201 of the socket 200, and the pin assembly 30 is plugged into one of the socket groups 202 of the socket 200. At this time, the second surface 11 covers the remaining socket groups 202 on the first surface 201 of the socket 200, preventing the remaining socket groups 202 of the socket 200 from being exposed, thereby avoiding the risk of electric shock caused by accidental touch by children, reducing the occurrence of safety hazards, and effectively preventing impurities such as dust and hair from entering the interior of the socket 200, thereby increasing the service life of the socket 200.
[0048] It should be understood that the pin assembly 30 provided in the embodiment of the present application may include three pins or two pins, which may be national standard pins, British standard pins, American standard pins or European standard pins, etc., to meet the needs of different users and adapt to the electrical standards of different countries and regions. The embodiment of the present application is not limited here.
[0049] A charging port 40 is provided on the third surface 12. One end of the charging port 40 is electrically connected to the circuit board 20, and the other end of the charging port 40 is exposed on the third surface 12. In this embodiment, the charging port 40 is used to connect to a mobile electronic device, so that when the adapter 100 is plugged into the socket 200, the mobile electronic device can be charged through the charging port 40.
[0050] Exemplarily, the charging interface 40 may be one or more of a USB interface, a Micro USB interface, a Lightning interface, and a Type-C interface, but is not limited thereto, so as to be applicable to mobile electronic devices without different interfaces.
[0051] In some embodiments, the outer edge of the second surface 11 is rectangular, and the lengths of two adjacent sides of the second surface 11 are both greater than 60 mm.
[0052] As a preferred embodiment of the present application, the outer edge contour of the second surface 11 is square, and the lengths of the two adjacent sides of the second surface 11 are both 86 mm, so that the outer contour of the adapter 100 matches the Chinese national standard power socket 200, and the overall shape is simple.
[0053] In some embodiments, the housing 10 further includes a fourth surface 13 , which is spaced apart from the second surface 11 and disposed adjacent to the third surface 12 ; and the spacing between the fourth surface 13 and the second surface 11 is greater than or equal to 7 mm.
[0054] Exemplarily, the distance between the fourth surface 13 and the second surface 11 is 7 mm, that is, the thickness of the adapter 100 is 7 mm. The adapter 100 of this thickness occupies a small space and can be plugged into the socket 200 in some narrow spaces, such as the socket 200 behind a sofa or a table, avoiding occupying space and making it convenient for users to use.
[0055] In some embodiments, the third surface 12 is provided with a gripping position 121. In this embodiment, the gripping position 121 can be a groove, a protrusion or a handle, which is convenient for the user to hold, thereby helping the user to plug and unplug the adapter 100 more easily.
[0056] Please refer to Figure 5 and Figure 6 The adapter 100 also includes a retractable data cable assembly 50, which includes a winding component 51 and a data cable 52. The winding component 51 is disposed in the housing 10, and the data cable 52 includes a cable 521 and a power terminal 522. One end of the cable 521 is wound around the winding component 51 and electrically connected to the circuit board 20, and the other end of the cable 521 is electrically connected to the power terminal 522, which is exposed outside the third surface 12.
[0057] In this embodiment, the power terminal 522 is used to connect to a mobile electronic device to charge the mobile electronic device. When the adapter 100 is still connected to the socket 200, the user can pull the cable 521 to adjust the length of the data cable 52 exposed outside the housing 10, thereby facilitating charging of the mobile electronic device (such as a mobile phone, tablet, mobile power bank, etc.), avoiding the situation where the data cable 52 is too short and cannot charge the mobile electronic device, and reducing the risk of the data cable 52 being broken or damaged.
[0058] Exemplarily, the power terminal 522 may be one or more of a USB interface, a Micro USB interface, a Lightning interface, and a Type-C interface, but is not limited thereto, so as to be applicable to mobile electronic devices without different interfaces.
[0059] For further information, please refer to Figure 6 , the retractable data cable assembly 50 further includes a carrying body 53, and the winding member 51 is disposed in the carrying body 53;
[0060] The winding component 51 includes a terminal member 511, a rotating member 512 and a reset member 513. The terminal member 511 is rotatably arranged on the carrier body 53, and the terminal member 511 is electrically connected to the circuit board 20; the rotating member 512 is connected to the terminal member 511 and rotates coaxially with the terminal member 511. One end of the cable 521 is connected to the rotating member 512 and electrically connected to the terminal member 511, and the other end of the cable 521 extends out of the shell 10. The cable 521 is at least partially wound around the side of the rotating member 512; one end of the reset member 513 is connected to the carrier body 53, and the other end of the reset member 513 is connected to the rotating member 512. The reset member 513 is used to apply a reset torque force to the rotating member 512.
[0061] When the user pulls the cable 521, the cable 521 drives the rotating member 512 and the reset member 513 to rotate, and the reset member 513 is in a tightened and energy-storing state; when the user releases the cable 521, the reset member 513 resets and causes the rotating member 512 to rotate in the opposite direction, while driving the cable 521 to retract, thereby realizing automatic retraction of the data cable 52 and facilitating the storage of the data cable 52.
[0062] For example, the reset member 513 can be a spring, which utilizes the elasticity of the spring to apply a restoring torque to the rotating member 512, thereby maintaining the stability and reliability of the elastic recovery. Of course, the reset member 513 can also be other elastic components, as long as it can provide a restoring force when the rotating member 512 rotates to ensure that the rotating member 512 has a tendency to return to its original position.
[0063] Please continue to refer to Figure 5 and Figure 6 The retractable data cable assembly 50 also includes a locking and releasing mechanism 54, which includes a button 541 and an elastic member 542. The button 541 is slidably disposed on the shell 10, and the button 541 is at least partially exposed outside the shell 10. The button 541 is used to lock or unlock the cable 521. The elastic member 542 is connected to the button 541 and is used to drive the button 541 to lock the cable 521.
[0064] In the initial state, the elastic action of the elastic member 542 drives the button 541 to lock the cable 521. At this time, the cable 521 is locked and cannot be pulled; when the user presses the button 541, the cable 521 is in the unlocked state. At this time, the cable 521 can be pulled to adjust the length extending outside the shell 10; after the adjustment is completed, the resetting action of the elastic member 542 causes the button 541 to re-lock the cable 521, so that the cable 521 stops at the position required by the user.
[0065] By providing a locking and releasing mechanism 54 in the embodiment of the present application, the user can pull out the cable 521 to the required length as needed, and stop the cable 521 at any desired position for user convenience; and when the cable 521 is not needed, part of the cable 521 can be retracted into the housing 10 for easy storage and carrying.
[0066] In some embodiments, the carrier body 53 is provided with a clamping plate 531, and a clamping space is formed between the clamping plate 531 and the button 541. The cable 521 is at least partially passed through the clamping space. The button 541 is used to slide relative to the clamping plate 531 under the action of external force to unlock the cable 521. The elastic member 542 is used to drive the button 541 to slide relative to the clamping plate 531 when the external force of the button 541 is removed to lock the cable 521.
[0067] When the button 541 is not pressed, due to the action of the elastic member 542, the cable 521 is squeezed by the button 541 and the clamping plate 531 and will not be pulled, and the cable 521 stops at the position where the user needs to use it; when the button 541 is pressed, the clamping force of the cable 521 is released. At this time, the user can pull the cable 521 and adjust the extended length of the cable 521 to meet the user's usage needs.
[0068] Please refer to Figure 6 and Figure 7 The supporting body 53 is also provided with a mounting plate 532, and the mounting plate 532 is spaced apart from the clamping plate 531; the button 541 includes a first panel 5411 and a second panel 5412 arranged back to back, the first panel 5411 is connected to the second panel 5412, and the first panel 5411 is exposed outside the shell 10, the second panel 5412 is located between the clamping plate 531 and the mounting plate 532, and the second panel 5412 and the clamping plate 531 form a clamping space, the elastic member 542 is located between the second panel 5412 and the mounting plate 532, and the two ends of the elastic member 542 are respectively connected to the second panel 5412 and the mounting plate 532.
[0069] In this embodiment, the user can control the sliding of the second panel 5412 through the first panel 5411 and adjust the distance between the second panel 5412 and the clamping plate 531 to achieve clamping, locking and releasing of the cable 521.
[0070] Exemplarily, the cable 521 is in the shape of a flat strip so that it can pass through the clamping space formed by the clamping plate 531 and the second panel 5412, and be clamped and fixed by the clamping plate 531 and the second panel 5412, with good locking stability and not easy to slip; the elastic member 542 can be a spring or a coil spring, including but not limited to these, to be used for resetting the button 541.
[0071] Furthermore, the button 541 also includes a third panel 5413 and a fourth panel 5414 arranged back to back, the third panel 5413 extends from one end of the first panel 5411 to one end of the second panel 5412, and the fourth panel 5414 extends from the other end of the first panel 5411 to the other end of the second panel 5412. The first panel 5411, the second panel 5412, the three panels and the fourth panel 5414 are combined to form a through groove 5415, and the clamping plate 531 is at least partially located in the through groove 5415 to maintain the connection between the clamping plate 531 and the button 541, so that the button 541 can slide relative to the clamping plate 531 and is not easily detached, thereby ensuring that it can be clamped and fixed by the first panel 5411 and the clamping plate 531 of the button 541.
[0072] Please refer to Figure 8 The embodiment of the present application further provides a plug 300, comprising the adapter 100 and a power cord 301 as described above. The housing 10 of the adapter 100 is provided with a wire hole, and the power cord 301 passes through the wire hole to be electrically connected to the circuit board 20.
