Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a power adapter, such as Figures 1 to 3As shown, the power adapter includes a main housing 1, a telescopic data cable module 2, a circuit module 3, and a support isolation plate 4. The support isolation plate 4 is installed inside the housing and divides the space inside the housing into a first mounting cavity 11 and a second mounting cavity 12. The telescopic data cable module 2 is located in the first mounting cavity 11 and is installed on the first side 41 of the support isolation plate 4 located in the first mounting cavity 11. The circuit module 3 is located in the second mounting cavity 12 and is installed on the second side 42 of the support isolation plate 4 located in the second mounting cavity 12. The telescopic data cable module 2 and the circuit module 3 are electrically connected.

[0030] The power adapter of this utility model has a supporting isolation plate 4 inside the main housing 1. The supporting isolation plate 4 divides the space inside the housing into a first mounting cavity 11 and a second mounting cavity 12. The telescopic winding data cable module 2 is located in the first mounting cavity 11 and is installed on the first side 41 of the supporting isolation plate 4 in the first mounting cavity 11. The circuit module 3 is located in the second mounting cavity 12 and is installed on the second side 42 of the supporting isolation plate 4 in the second mounting cavity 12. This achieves reasonable space utilization and effective installation of the telescopic winding data cable module 2 and the circuit module 3. At the same time, the use of a separate supporting isolation plate 4 as a partition component provides high safety and higher reliability of partitioning and installation. The telescopic winding data cable module 2 and the circuit module 3 are both installed on the first side 41 and the second side 42 of the supporting isolation plate 4, forming a module with the supporting isolation plate 4, which is convenient for assembly into the main housing 1 and is easy to assemble.

[0031] Optionally, such as Figure 4 and Figure 5 As shown, two oppositely positioned buckles 411 are provided at two opposite corners of the first side 41, and two first limiting baffles 412 are provided at the other two opposite corners. The telescopic winding data cable module 2 includes a housing 21, with the two buckles 411 fastening to the edge of the housing 21 and the two first limiting baffles 412 blocking the sides of the housing 21. By providing buckles 411 at two opposite corners of the supporting isolation plate 4, the buckles 411 can be firmly fastened to the edge of the housing 21 of the telescopic winding data cable module 2. This design not only provides a stable fixing method but also effectively prevents the telescopic winding data cable module 2 from loosening or shifting due to external forces (such as pulling, vibration, etc.) during use. The first limiting baffles 412 at the other two opposite corners are used to limit the side position of the housing 21. The limiting baffles can prevent the housing 21 from shaking or shifting in the horizontal direction, further enhancing the stability of the telescopic winding data cable module 2. The design of the buckle 411 and the first limiting plate 412 makes the installation process of the telescopic winding data cable module 2 simpler. Just align the outer shell 21 with the buckle 411 and the limiting plate, and you can fix it with a gentle snap.

[0032] The housing 21 also contains a turntable, on which the data cable 22 of the telescopic winding data cable module 2 is wound up. A coil spring can be installed on the turntable to provide the driving force for winding up the data cable 22. The telescopic winding data cable module 2 can be a commonly used telescopic winding data cable module 2, which will not be described in detail here.

[0033] Furthermore, each of the two first limiting baffles 412 has a limiting rib 4121 extending along the height direction of the first limiting baffle 412 on its side facing the outer casing 21. A limiting groove 211 is provided on the side of the outer casing 21 corresponding to the limiting rib 4121, and the limiting rib 4121 is engaged in the limiting groove 211. The cooperation between the limiting rib 4121 and the limiting groove 211 prevents the data cable 22 from rotating under force during extension and retraction, further improving the installation stability of the telescopic winding data cable module 2 and ensuring the extension and retraction stability of the data cable 22. The telescopic winding data cable module 2 can also be further adhered to the first side 41 using adhesive or the like.

[0034] Specifically, multiple second limiting baffles 421 are provided along the edge of the second side 42, and the second limiting baffles 421 are positioned on the side of the circuit module 3. By positioning the second limiting baffles 421 on the side of the circuit module 3, the second limiting baffles 421 can effectively restrict the horizontal movement of the circuit module 3, preventing it from shaking or shifting due to external forces (such as vibration or impact) during use. The design of multiple limiting baffles provides multi-point support, making the fixation of the circuit module 3 on the supporting isolation plate 4 more uniform and stable, further enhancing its stability. The circuit module 3 can also be further adhered to the second side 42 with adhesive or the like. Specifically, the circuit module 3 includes various circuit boards, components, and other electrical-related parts required by the power adapter. The circuit module 3 is integrally formed by encapsulation injection molding. Through the encapsulation injection molding process, the various components of the circuit module 3 are encapsulated as one unit, which can effectively reduce the loosening or damage of components caused by mechanical vibration, impact, or external forces. Furthermore, this integrated design enhances the anti-interference capability of circuit module 3, reduces the risk of electromagnetic compatibility (EMC) issues, and facilitates modular assembly.

[0035] Furthermore, such as Figure 2 As shown, the power adapter also includes a bottom shell 5, which is installed at the bottom of the main shell 1 and seals the second mounting cavity 12. A pin 6 is inserted into the bottom shell 5, and the pin 6 is electrically connected to the circuit module 3. The pin 6 can be a rotating pin 6, which can be stored on the bottom shell 5. In use, the pin 6 is inserted into the socket of the power outlet to draw power.

[0036] Furthermore, such as Figure 1 , Figure 6 and Figure 7As shown, the main housing 1 has a cable outlet 131 on its side. The telescopic winding data cable module 2 includes a data cable 22 with one end of a data cable connector 221 that can extend and retract. The data cable connector 221 extends from the cable outlet 131 to the outside of the main housing 1. A semi-enclosed part 413 is integrally formed on the first side 41 corresponding to the cable outlet 131, and the semi-enclosed part 413 blocks part of the cable outlet 131. In this way, the size of the outlet 131 can be set to be larger, making it convenient for the data cable connector 221 to pass through the outlet 131 and lead out to the outside of the main housing 1. On this basis, the semi-enclosed part 413 further blocks part of the outlet 131, which can ensure that the data cable 22 can be stretched and contracted normally, while part of the outlet 131 can be blocked and sealed by the semi-enclosed part 413, avoiding the exposure of the inside of the power adapter, improving the sealing performance, reducing safety hazards, and making it less likely for the data cable connector 221 to retract into the main housing 1, which is conducive to normal use.

[0037] The data cable connector 221 serves as the charging head for the data cable 22 and is used to plug into the charging port of mobile phones and other electronic devices for charging. The data cable connector 221 can be a Type-C connector, a Lightning connector, or a Micro-USB connector, etc.

[0038] A side shell 13 is mounted on the side of the main housing 1, and a cable outlet 131 is formed on the side shell 13. By designing the cable outlet 131 on the side shell 13, rather than directly on the side of the main housing 1, the side shell 13 is designed as an independent component, which facilitates the processing of the cable outlet 131 and the assembly of the main housing 1.

[0039] Furthermore, the side shell 13 is provided with a receiving groove 132, in which the cable outlet 131 is opened, and the data cable connector 221 is housed in the receiving groove 132. The receiving groove 132 can provide a fixed storage location for the data cable connector 221, improving the overall compactness of the power adapter.

[0040] The inner surface of the side shell 13 is provided with a cable passage portion 133, and a cable passage groove 1331 is formed on the cable passage portion 133. The cable passage groove 1331 corresponds to and communicates with the part of the cable outlet 131 that is not enclosed by the semi-enclosed member 413. The data cable 22 passes through the cable passage groove 1331. The data cable 22 passes through the cable passage groove 1331 and exits from the cable outlet 131. The cable passage groove 1331 provides a fixed channel for the data cable 22, ensuring that the data cable 22 moves along a predetermined path during the stretching and contraction process, which is beneficial to the stable extension and contraction of the data cable 22.

[0041] Furthermore, the semi-enclosed component 413 includes an adapter 4131, which is positioned at the side opening of the cable tray 1331 to close the side opening of the cable tray 1331. The adapter 4131 effectively closes the side opening of the cable tray 1331, further limiting the data cable 22 and improving its telescopic stability. Simultaneously, the adapter 4131 further shields the interior of the power adapter, reducing the area exposed through the cable outlet 131, further improving safety and preventing foreign objects from entering.

[0042] The semi-enclosed component 413 also includes a shielding part 4132, which is connected to the adapter part 4131. The shielding part 4132 and the adapter part 4131 are L-shaped as a whole, and the shielding part 4132 blocks part of the cable outlet 131. By blocking part of the cable outlet 131 through the shielding part 4132, the semi-enclosed component 413 reduces the exposed area of ​​the cable outlet 131 and prevents dust, foreign objects, and liquids from entering the power adapter from the cable outlet 131, which could damage the charger or cause safety hazards. The L-shape of the shielding part 4132 and the adapter part 4131 allows the shielding part 4132 to block part of the cable outlet 131, while the adapter part 4131 can be positioned at the side opening of the cable tray 1331 to seal the side opening of the cable tray 1331.

[0043] Specifically, the first limiting baffle 412 is connected at both ends to the adapter part 4131 and the blocking part 4132, respectively. The first limiting baffle 412 connects the adapter part 4131 and the blocking part 4132 together, forming a more stable structure, improving the structural stability of the semi-enclosed part 413, and also improving the structural stability of the first limiting baffle 412.
