DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0033] Please refer to Figures 1-7 A power adapter with a flexible conductive structure comprises a power adapter body 100 and a connecting line 101. The power adapter body 100 comprises a shell 102 and a base 103 connected to the shell 102.

[0034] A first mounting chamber is formed in the shell 102. An inner bottom surface of the base 103 is provided with a second mounting chamber 105. The first mounting chamber and the second mounting chamber 105 cooperate to form an accommodating chamber 106. A front-to-back PCBA board 107 is fixedly arranged in the accommodating chamber 106. The connecting line 101 is electrically connected to the PCBA board 107.

[0035] The inner bottom surface of the second mounting chamber 105 is recessed to form a third mounting chamber 108 which is in communication with the accommodating chamber 106. A pin member 109 is arranged in the third mounting chamber 108. The lower end of the pin member 109 extends out of the lower end surface of the base 103 through the inner bottom surface of the third mounting chamber 108.

[0036] The PCBA board piece 107 is fixedly provided with a left-right oriented pin sliding rail piece 110, the upper end of the pin piece 109 is in electric sliding abutting cooperation with the pin sliding rail piece 110, the inner bottom surface of the third mounting chamber 108 is provided with a rotatable steering adjusting piece 111, and the pin piece 109 is embedded in the steering adjusting piece 111;

[0037] By adopting the flexible conductive structure, especially the electric sliding abutting cooperation between the pin piece 109 and the pin sliding rail piece 110, greater flexibility and adaptability can be provided when being inserted into the socket, and the phenomenon of insertion difficulty or jamming caused by deformation of the socket spring sheet is reduced;

[0038] Since the pin piece 109 is embedded in the rotatable steering adjusting piece 111, the pin piece 109 is appropriately adjusted in angle according to actual conditions, so that the direct hard impact on the socket spring sheet is reduced, the risk of functional failure caused by wear during long-term use is reduced, and the durability and reliability of the overall device are improved;

[0039] Through the above design, the user will feel a smoother operation experience when inserting the power adapter into the socket, and potential safety hazards are reduced, which is particularly important for application scenarios where the socket position is difficult to access or the space is limited;

[0040] The design of the first mounting chamber, the second mounting chamber 105 and the third mounting chamber 108 enables the PCBA board piece 107, the pin piece 109 and other components to be compactly and orderly arranged inside the power adapter, which not only ensures the effective connection and work between the components, but also realizes the miniaturization and light weight of the device, facilitating carrying and use.

[0041] In the embodiment of the utility model, the inner bottom surface of the third mounting chamber 108 is provided with an arc-shaped mounting slot 112, the steering adjusting piece 111 comprises a spherical steering piece 113 arranged in the arc-shaped mounting slot 112, the spherical steering piece 113 is in rotating cooperation in the arc-shaped mounting slot 112, and the pin piece 109 is embedded in the spherical steering piece 113;

[0042] The spherical steering piece 113 can freely rotate in the arc-shaped mounting slot 112, so that the pin piece 109 can flexibly adjust the insertion angle according to the specific conditions of the socket, improve the adaptability and flexibility of the power adapter plug and the socket, and especially in the case where the socket position is inconvenient or the space is limited, the user can more easily complete the plug-in operation;

[0043] Due to the omnidirectional angle adjustment capability provided by the spherical turning piece 113, the pin piece 109 can better adapt to the position and shape changes of the socket spring sheet, thereby reducing the resistance during plugging and avoiding the problem of jamming or difficulty in insertion caused by deformation of the spring sheet due to repeated plugging, improving the convenience of use and the satisfaction of users;

[0044] The design of the spherical turning piece 113 reduces the pressure concentration point of the pin piece 109 directly on the socket spring sheet, disperses the force, reduces the wear speed between the pin piece 109 and the socket spring sheet during long-term use, and prolongs the service life of the power adapter and the socket;

[0045] Using the spherical turning piece 113 as the turning adjusting piece 111 not only realizes efficient space utilization, but also simplifies the overall structure design, which is helpful to reduce the volume of the power adapter, making it more compact, light, portable and easy to store;

[0046] By ensuring that the pin piece 109 can be smoothly and stably inserted into the socket, reducing the safety hazards caused by forced insertion or incorrect insertion, such as arc discharge, the safety of the user is ensured.

[0047] In the embodiment of the utility model, the pin sliding rail piece 110 includes the first sliding rail piece 114 and the second sliding rail piece 115 fixed on the PCBA plate piece 107, the first sliding rail piece 114 and the second sliding rail piece 115 are opposite and inclined to form a spread shape, and the pin piece 109 is provided with the first sliding groove 116 and the second sliding groove 117 embedded and matched with the first sliding rail piece 114 and the second sliding rail piece 115 respectively;

[0048] The first sliding rail piece 114 and the second sliding rail piece 115 in the spread shape provide a more stable guiding effect for the pin piece 109, when the pin piece 109 slides along the sliding rail piece, the design in the spread shape can effectively disperse and offset the lateral force, ensure that the pin piece 109 remains stable during movement, and reduce the deviation or shaking caused by external force;

[0049] The sliding rail design in the spread shape allows the pin piece 109 to make a certain degree of angle adjustment according to actual needs, and when facing different specifications or slightly deviated sockets, the pin piece 109 can adaptively find the best insertion angle, improving the compatibility between the adapter and the socket;

[0050] The installation process of the pin piece 109 becomes simpler and faster, and only needs to be gently pushed into the sliding rail piece to complete the assembly, without the need for complex calibration steps, saving time and reducing manufacturing cost.

[0051] The end portions of the first sliding rail piece 114 and the second sliding rail piece 115 are respectively provided with first arc-shaped abutting portions 118, and the upper inner walls of the first sliding groove 116 and the second sliding groove 117 are respectively provided with arc-shaped abutting grooves 119 which abut and cooperate with the first arc-shaped abutting portions 118;

[0052] The cooperation between the first arc-shaped abutting portions 118 and the arc-shaped abutting grooves 119 can ensure that the pin piece 109 remains stable when being adjusted in the turning direction between the first sliding rail piece 114 and the second sliding rail piece 115, and even if the pin piece 109 is subjected to a lateral force, the arc-shaped structure can effectively disperse the pressure, so that the pin piece 109 cannot easily deviate from the track, and the stability of the overall device is enhanced;

[0053] Since the direct hard impact and friction loss are reduced, the design of the first arc-shaped abutting portions 118 and the arc-shaped abutting grooves 119 can significantly reduce the wear rate between components, thereby improving the durability of the entire power adapter.

[0054] In the embodiment of the utility model, the end portions of the first sliding rail piece 114 and the second sliding rail piece 115 are respectively provided with limiting abutting portions 120, the limiting abutting portions 120 are communicated with the first arc-shaped abutting portions 118, and the limiting abutting portions 120 are abutted and cooperated with the side walls of the first sliding groove 116;

[0055] The existence of the limiting abutting portions 120 can effectively limit the movement range of the pin piece 109 between the first sliding rail piece 114 and the second sliding rail piece 115, prevent the pin piece 109 from deviating from the predetermined track or being displaced unnecessarily due to excessive movement, and ensure that the pin piece 109 can remain stable at an accurate position, thereby improving the working reliability of the entire device;

[0056] By limiting the maximum stroke of the pin piece 109, the limiting abutting portions 120 can help to avoid potential risks caused by misoperation, such as damage caused by accidental complete extraction or excessive insertion of the pin piece 109, and the like, and this design provides additional safety protection for the user, which is particularly important in the use scene of frequent plugging and unplugging.

[0057] In the embodiment of the utility model, the lower end of the spherical turning piece 113 is integrally extended downward with a reinforcing pipe 121, and the lower end of the pin piece 109 passes out from the lower end of the reinforcing pipe 121;

[0058] The design of the reinforcing pipe 121 increases the overall mechanical strength of the spherical turning piece 113, especially when the pin piece 109 is frequently rotated or subjected to external pressure, which can effectively prevent the spherical turning piece 113 from being deformed or damaged, thereby not only improving the durability of the product, but also prolonging the service life thereof;

[0059] The reinforcing pipe 121 provides an additional guide path for the pin 109, ensuring that the pin 109 maintains the correct orientation during angle adjustment and insertion into the socket, which reduces the risk of poor contact due to the pin 109 deviating from the intended trajectory, thereby improving the reliability of the electrical connection;

[0060] By embedding the pin 109 into the spherical turning piece 113 and guiding it through the reinforcing pipe 121, the entire structure is more stable, especially when inserting the socket at different angles, the reinforcing pipe 121 helps to distribute the force applied to the pin, preventing structural damage or functional failure due to excessive force on a single point.

[0061] In the embodiment of the utility model, the lower end of the pin 109 is formed with a boss 122, the lower end of the reinforcing pipe 121 is provided with an elastic element mounting groove 123, a spring 124 is arranged in the elastic element mounting groove 123, the spring 124 is sleeved on the pin 109, one end of the elastic element abuts against the boss 122, the other end of the elastic element abuts against the inner bottom surface of the elastic element mounting groove 123;

[0062] The presence of the spring 124 provides a cushioning effect for the pin 109, when the user inserts the pin into the socket, the spring can absorb part of the impact force, reducing the discomfort caused by hard collision;

[0063] The arrangement of the spring 124 ensures that the pin 109 maintains proper pressure contact with the socket, even if the spring inside the socket deforms slightly or wears out, the spring can compensate for these changes, ensuring good electrical contact and avoiding unstable current caused by poor contact;

[0064] The cooperation of the boss 122 and the spring 124 allows the pin 109 to have a certain expansion space, which increases the adaptability of the pin 109 to different socket specifications and use conditions, especially when facing some non-standard or slightly deviated sockets, the spring 124 can help adjust the position of the pin, ensuring stable and reliable electrical connection;

[0065] Through the tensioning action of the spring 124, the first arc-shaped abutting portion 118 at the end of the first and second sliding rail pieces 114 and 115 and the arc-shaped abutting groove 119 are always in close abutting cooperation, making the electrical connection between the first and second sliding rail pieces 114 and 115 and the pin 109 more effective.

[0066] In the embodiment of the utility model, the included angle between the first and second sliding rail pieces 114 and 115 is in the range of 30°-45°;

[0067] By precisely controlling the included angle between the first sliding rail member 114 and the second sliding rail member 115 within the range of 30°-45°, an ideal guiding path can be provided for the plug pin member 109, which is neither too narrow to cause difficulty or jamming in insertion nor too wide to lose effective guiding effect, and which ensures smooth movement of the plug pin member 109 along the predetermined track, thereby improving the accuracy and stability of operation.

[0068] The angle range of 30°-40° helps maintain the compactness and stability of the entire structure while ensuring sufficient space for flexible movement of the plug pin member 109, which not only helps reduce unnecessary lateral sway but also effectively disperses external forces received by the plug pin member 109, thereby enhancing the structural strength and durability of the overall device.

[0069] In the embodiments of the utility model, the upper end surface of the first sliding rail member 114 and the second sliding rail member 115 is provided with a left-right oriented second arc-shaped abutting portion 125, which abuts and cooperates with the arc-shaped abutting groove 119.

[0070] The cooperation between the second arc-shaped abutting portion 125 and the arc-shaped abutting groove 119 can significantly improve the sliding stability of the plug pin member 109 on the sliding rail, and the arc-shaped structure can effectively reduce friction and provide a smoother transition path.

[0071] Since the upper end of the plug pin member 109 performs circular motion during left-right rotation, the second arc-shaped abutting portion 125 slides and abuts within the arc-shaped abutting groove 119 during fine adjustment rotation of the plug pin member 109 in the left-right direction, and since the second arc-shaped abutting portion 125 is arranged along the left-right orientation of the upper end surface of the first sliding rail member 114 and the second sliding rail member 115, it can better cooperate with the rotation adjustment of the upper end of the plug pin member 109.

[0072] The circular motion of the upper end of the plug pin member 109 during forward-backward rotation can be adapted by the rotation of the first arc-shaped abutting portion 118 within the arc-shaped abutting groove 119 and the slight elastic deformation of the first sliding rail member 114 and the second sliding rail member 115.

[0073] In one embodiment, in order to ensure stable installation of the first sliding rail member 114 and the second sliding rail member 115, an auxiliary positioning block is arranged on the inner bottom surface of the base 103 to assist in fixing the first sliding rail member 114 and the second sliding rail member 115, thereby enhancing the stress effect of the first sliding rail member 114 and the second sliding rail member 115, reducing the stress on the PCBA board, and avoiding loosening of the solder joints of the first sliding rail member 114 and the second sliding rail member 115 on the PCBA board.

[0074] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
