Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a power adapter. Background Technology

[0002] A power adapter is a common accessory for electronic devices. Its main function is to convert the input power (usually AC mains power, such as 220V AC or 110V AC) into the power form required by the device (usually low-voltage DC). For example, it can convert 220V AC to 5V or higher DC to charge a mobile phone.

[0003] Conventional power adapters typically require an external data cable for charging. With technological advancements, some power adapters now integrate a retractable data cable module. The cable can be extended for charging and retracted into the adapter when not in use, eliminating the need for an external cable and making it more convenient.

[0004] However, the connector of the data cable leading out of the power adapter housing on the telescopic winding data cable module is relatively large. If the lead-out opening of the power adapter housing is too small, the data cable connector will be difficult to lead out; if the lead-out opening is too large, the inside of the power adapter will be exposed, the sealing will be poor, and there will be safety hazards. In addition, the data cable connector is easy to retract into the housing, which is not conducive to normal use. Utility Model Content

[0030] 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.

[0031] This utility model embodiment provides a power adapter, such as Figure 1 and Figure 2As shown, the power adapter includes a main housing 1, a telescopic data cable module 2, and a semi-enclosed component 41. The telescopic data cable module 2 includes a data cable 21 with one end of a data cable connector 211 that can extend and retract. The telescopic data cable module 2 is installed inside the main housing 1. The main housing 1 has an outlet 111a. The data cable connector 211 extends from the outlet 111a to the outside of the main housing 1. The semi-enclosed component 41 is installed inside the main housing 1 and located at the outlet 111a. The semi-enclosed component 41 partially blocks the outlet 111a.

[0032] The power adapter of this utility model is provided with a semi-enclosed component 41, which is installed inside the main housing 1 and located at the cable outlet 111a. The semi-enclosed component 41 partially blocks the cable outlet 111a. In this way, the size of the cable outlet 111a can be set to be larger, so that the data cable connector 211 can pass through the cable outlet 111a and be led out of the main housing 1. On this basis, by further blocking part of the cable outlet 111a by the semi-enclosed component 41, it is possible to ensure that the data cable 21 can be stretched and contracted normally, while part of the cable outlet 111a can be blocked and sealed by the semi-enclosed component 41, avoiding 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 211 to retract into the main housing 1, which is beneficial to normal use.

[0033] Specifically, the retractable winding data cable module 2 can be a commonly used retractable winding data cable module 2, which will not be described in detail here. The data cable connector 211 serves as the charging head of the data cable 21 and is used to be plugged into the charging port of mobile phones and other electronic devices for charging. The data cable connector 211 can be a Type-C connector, a Lightning connector, or a Micro-USB connector, etc.

[0034] Specifically, a side shell 11 is mounted on the side of the main housing 1, and the cable outlet 111a is formed on the side shell 11. Designing the cable outlet 111a on the side shell 11, rather than directly on the side of the main housing 1, makes the side shell 11 a separate component, facilitating the processing of the cable outlet 111a and the assembly of the main housing 1. A blocking protrusion 212 is provided on the portion of the data cable 21 located outside the main housing 1. The blocking protrusion 212 can engage with the cable outlet 111a. The blocking protrusion 212 prevents the data cable 21 from being excessively wound inside the main housing 1, allowing the data cable connector 211 to be stored in a suitable position in the receiving groove 111, such as the position where it is magnetically attracted to the magnet 113 described below.

[0035] Furthermore, the side shell 11 is provided with a receiving groove 111, and the cable outlet 111a is opened in the receiving groove 111. The data cable connector 211 is housed in the receiving groove 111. The receiving groove 111 can provide a fixed storage location for the data cable connector 211, improving the overall compactness of the power adapter.

[0036] like Figures 2 to 10As shown, the inner surface of the side shell 11 is provided with a cable passage portion 112, and a cable passage groove 112a is formed on the cable passage portion 112. The cable passage groove 112a corresponds to and communicates with the part of the cable outlet 111a that is not enclosed by the semi-enclosed member 41. The data cable 21 passes through the cable passage groove 112a. The data cable 21 passes through the cable passage groove 112a and exits from the cable outlet 111a. The cable passage groove 112a provides a fixed channel for the data cable 21, ensuring that the data cable 21 moves along a predetermined path during the stretching and contraction process, which is beneficial to the stable extension and contraction of the data cable 21.

[0037] Furthermore, the semi-enclosed component 41 includes an adapter 411, which is positioned at the side opening of the cable tray 112a to close the side opening of the cable tray 112a. The adapter 411 effectively closes the side opening of the cable tray 112a, further limiting the data cable 21 and improving its telescopic stability. Simultaneously, the adapter 411 further shields the interior of the power adapter, reducing the area exposed through the cable outlet 111a, further improving safety and preventing foreign objects from entering.

[0038] The semi-enclosed component 41 also includes a shielding portion 412, which is connected to the adapter portion 411. Both the shielding portion 412 and the adapter portion 411 are L-shaped, with the shielding portion 412 partially blocking the cable outlet 111a. By shielding part of the cable outlet 111a with the shielding portion 412, the semi-enclosed component 41 reduces the exposed area of ​​the cable outlet 111a, preventing dust, foreign objects, and liquids from entering the power adapter from the cable outlet 111a, thus preventing damage to the charger or safety hazards. The L-shape of the shielding portion 412 and the adapter portion 411 allows the shielding portion 412 to partially block the cable outlet 111a, while the adapter portion 411 can be positioned at the side opening of the cable tray 112a, sealing the side opening of the cable tray 112a.

[0039] The semi-enclosed component 41 also includes a connecting portion 413; on the side of the semi-enclosed component 41 away from the outlet 111a, the two ends of the connecting portion 413 are connected to the adapter portion 411 and the shielding portion 412 respectively. The connecting portion 413 connects the adapter portion 411 and the shielding portion 412 together, forming a more stable structure and improving the structural stability of the semi-enclosed component 41.

[0040] Furthermore, the telescopic winding data cable module 2 includes a housing 22, within which the data cable 21 can be telescopically wound. A locking groove 221 is provided on the side of the housing 22 in the height direction. A locking rib 413a is provided on the side of the connecting part 413 opposite to the adapter part 411 and the shielding part 412, corresponding to the locking groove 221. The locking rib 413a is engaged in the locking groove 221. The cooperation between the locking rib 413a and the locking groove 221 ensures a stable connection between the telescopic winding data cable module 2 and the semi-enclosed component 41. This design allows the telescopic winding data cable module 2 to fix the semi-enclosed component 41, facilitating the positioning and assembly of both the semi-enclosed component 41 and the telescopic winding data cable module 2. A pressure plate can also be provided on the main housing 1, pressing against the connecting part 413 to further fix the semi-enclosed component 41. Of course, the semi-enclosed part 41 can be further improved by providing a structure on the shielding part 412 that engages with the snap 42 of the main housing 1, which will not be described in detail here.

[0041] A magnet 113 is installed on the inner side of the side shell 11 at the location where the data cable connector 211 is housed in the receiving groove 111. The data cable connector 211 is magnetically absorbed into the receiving groove 111. By installing the magnet 113 on the inside of the side shell 11, the data cable connector 211 can be magnetically fixed in the receiving groove 111. This design ensures that the data cable connector 211 will not loosen or shift when stored away from use. The protective shell of the data cable connector 211 can be a metal shell that can be magnetically attracted to the magnet 113, or the data cable connector 211 can have a magnet 113 or an iron block installed inside it that magnetically attracts the magnet 113 on the inner side of the side shell 11.

[0042] Furthermore, the power adapter also includes a circuit module 3 and a supporting isolation plate 4. The supporting isolation plate 4 is installed inside the main housing 1 and axially divides the space inside the main housing 1 into a first mounting cavity and a second mounting cavity. The telescopic data cable module 2 is installed in the first mounting cavity, and the circuit module 3 is installed in the second mounting cavity. The data cable 21 is electrically connected to the circuit module 3. The supporting isolation plate 4 divides the interior of the main housing 1 into two independent mounting cavities. The first mounting cavity is used to install the telescopic data cable module 2, and the second mounting cavity is used to install the circuit module 3. This layered design can effectively utilize the internal space and avoid mutual interference between different functional modules. Through the layered design, the internal structure of the power adapter is more compact, improving the overall integration and making the power adapter smaller in size, easier to carry and use. The supporting isolation plate can separate the circuit module 3 from the telescopic data cable module 2, reducing electrical interference and short-circuit risks. The circuit module 3 and the data cable 21 module are installed in independent cavities, which can effectively prevent safety problems caused by electrical faults.

[0043] Furthermore, the supporting isolation plate 4 is provided with multiple clips 42, and the telescopic winding data cable module 2 is clipped onto the supporting isolation plate 4 via the clips 42. Furthermore, the semi-enclosed component 41 is integrally formed on the supporting isolation plate 4. The integral formation of the semi-enclosed component 41 with the supporting isolation plate 4 significantly improves the installation stability of the semi-enclosed component 41, and the installation of the semi-enclosed component 41 is completed as soon as the supporting isolation plate 4 is installed, simplifying installation. Specifically, the semi-enclosed component 41 is located in the first mounting cavity.

[0044] Specifically, the lower side of the shielding part 412 extends outward to form a stepped bottom edge 412a, the upper edge 412b of the shielding part 412 is engaged with the upper side of the outlet 111a, and the stepped bottom edge 412a is engaged with the lower side of the outlet 111a. The engagement design of the stepped bottom edge 412a and the upper edge 412b makes the shielding part 412 and the outlet 111a fit tightly together. This design makes the shielding part 412 firmly fixed at the outlet 111a in the height direction of the outlet 111a. The double engagement method can significantly improve the installation stability of the semi-enclosed part 41 and reduce loosening caused by external force or vibration.

[0045] Furthermore, circuit module 3 includes the necessary circuit board and various circuit components for the power adapter, which will not be described in detail here. The retractable data cable module 2 also has the necessary circuit board to achieve electrical connection between the data cable 21 and circuit module 3. The power adapter also includes a bottom shell 5 and pins 6. The bottom shell 5 is mounted on one end of the main shell 1, sealing the main shell 1. Pins 6 are mounted on the bottom shell 5 and electrically connected to the circuit board of the power module. Pins 6 are inserted into the power socket to draw power.
