Description
Technical Field
[0001] This utility model relates to the field of chargers, and in particular to a charger with built-in dual retractable data cables. Background Technology
[0002] With the widespread use of electronic devices, portable chargers have become necessities in people's daily lives. Currently, most chargers on the market have a single USB output port, requiring users to carry an additional data cable when out and about, which is prone to being forgotten or lost. To address this issue, some charger designs have emerged that integrate the data cable. However, these designs typically simply coil or place the data cable inside the casing, resulting in complex winding mechanisms, large space consumption, and an overall bulky charger that reduces portability. Furthermore, placing the data cable and charging circuit module in the same confined space may pose electromagnetic interference and potential safety risks. In addition, some designs place the plug and data cable outlet on adjacent sides of the casing; in actual use, when the charger is plugged into a wall socket, the data cable can obstruct the use of other sockets, leading to a poor user experience. Therefore, there is an urgent need for a compact, integrated charger that effectively isolates the circuitry and data cable, and is easy to plug and unplug. Utility Model Content

[0031] This utility model proposes a charger with built-in dual retractable data cables.
[0032] In this embodiment of the utility model, such as Figures 1 to 4 As shown:
[0033] The device includes a housing 1 and pins 2 mounted on the housing 1. A first partition 31 is provided inside the housing 1, dividing the interior into an upper and a lower receiving space. A charging circuit module 4 containing components such as a transformer and capacitors is located in the lower receiving space. A second partition 32 is provided in the upper receiving space, dividing it into two independent cable compartments 33. Each cable compartment 33 contains a retractable USB data cable 5. The protruding end of the pin 2 is located on one side of the housing 1, and the free ends of the pin 2 and the data cable are located on opposite sides of the housing 1.
[0034] It should be noted that the charging circuit module 4 and the retractable USB data cable 5 are existing technologies, and their specific structural principles will not be described in detail here.
[0035] Specifically, based on the above-described embodiments, the first partition 31 and the second partition 32 are integrally formed to constitute an integral support 3 that is supported inside the housing 1. This integral support 3 is made of engineering plastic and is formed in one step through injection molding, forming a robust internal skeleton structure, which improves the structural strength and assembly accuracy of the product.
[0036] Furthermore, the front side of the integral bracket 3 is provided with a forward-protruding insertion portion 34. Correspondingly, a slot 11 matching the shape of the insertion portion 34 is provided on the inner front wall of the housing 1. During assembly, the insertion portion 34 of the integral bracket 3 is accurately inserted into the slot 11 of the housing 1, realizing the rapid pre-positioning and radial limiting of the bracket 3.
[0037] Specifically, each of the cable compartments 33 is provided with an arc-shaped baffle 35. The concave shape of the arc-shaped baffle 35 is adapted to a portion of the outer periphery of the retractable USB data cable 5 housing. When the retractable USB data cable 5 is installed in the cable compartment 33, the arc-shaped baffle 35 can cover and constrain the portion of the outer periphery of the data cable housing, thus fixing it in place.
[0038] Specifically, as a further optimization for securing the retractable USB data cable 5, a locking part 36 is provided on the arc-shaped baffle 35 and / or the first partition 31. Simultaneously, a corresponding slot 51 is provided on the outer shell of the retractable USB data cable 5. During assembly, the locking part 36 engages with the slot 51 to further secure the data cable outer shell, preventing it from shifting during retraction.
[0039] Specifically, in a preferred embodiment of this utility model, the front and rear sides of the housing 1 are open structures. The housing 1 has its front open portion closed by a front cover plate 12 and its rear open portion closed by a rear cover plate 13. The pins 2 are disposed on the front cover plate 12, forming a complete appearance together with the housing 1.
[0040] Specifically, for electrical safety reasons, the arc-shaped baffle 35 described in the aforementioned embodiment is made of electrically insulating material. Its vertically extending plate forms a physical isolation barrier within the housing 1 to create reliable electrical isolation between the live components of the plug 2, such as wires and metal connectors, and the retractable USB data cable 5, ensuring safe use.
[0041] Specifically, as a preferred embodiment of the plug 2, the plug 2 disposed on the front cover plate 12 has a rotating and concealed structure. The plug 2 is rotatably disposed on the front cover plate 12 via a pivot, so that it has a retracted state stored inside the housing 1 and a working state that is rotated out for insertion, thereby improving the convenience and safety of carrying.
[0042] Specifically, a positioning groove 14 is provided on the outer surface of the rear cover plate 13. The connector 52 on the free end of each retractable USB data cable 5 is fixed to the corresponding positioning groove 14 by magnetic attraction. Specifically, the positioning groove 14 is provided with a magnet 15 that can magnetically attract and fix the connector 52. This design allows the connector 52 to be neatly and securely stored after the data cable is retracted.
[0043] Specifically, this utility model can further expand its functionality by providing a display structure on the outer surface of the housing 1 to display status information such as charging voltage and current. Specifically, a digital tube 6 is provided inside the housing 1, and the position of the back cover corresponding to the digital tube 6 is transparent or light-transmitting; alternatively, the entire back cover is transparent or light-transmitting. Simultaneously, at least one fixed USB output port 7 is embedded in the housing 1, which is electrically connected to the internal charging circuit module 4, providing the user with an additional interface for charging via the included data cable.
[0044] This invention uses a first partition to divide the interior of the housing into an upper and lower accommodating space, with the charging circuit module located in the lower space. Simultaneously, a second partition divides the upper space into two independent cable compartments to accommodate two retractable USB data cables, creating a clear three-dimensional spatial layout. This structure firstly completely isolates the high-voltage charging circuit from the low-voltage USB data cables in physical space, effectively avoiding electrical interference and improving product safety and reliability. Secondly, this three-dimensional stacking scheme fully utilizes the vertical space inside the housing, integrating two built-in data cables while avoiding the excessive planar area problem associated with traditional side-by-side layouts. This achieves miniaturization and compactness of the overall charging head structure, significantly enhancing portability. Furthermore, by placing the prongs and the free ends of the data cables on opposite sides of the housing, when the charger is plugged into a wall socket, the extended data cables naturally face the opposite direction to the socket's plane, fundamentally solving the technical problem of data cables obstructing the use of adjacent sockets and greatly optimizing the user experience in real-world scenarios.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
