[0033] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0034] like Figures 1 to 8 As shown, this utility model discloses a multi-connector mobile phone charger, which includes a charging box 1, a charging circuit board 2, and multiple charging connectors 3. The charging box 1 has multiple mobile phone holders 4 detachably mounted on its upper side, each holder having a recessed placement groove 41. Each charging connector 3 is fitted into the charging box 1 and extends into the placement groove 41 of each mobile phone holder 4. The charging circuit board 2 is located inside the charging box 1 and includes a main input circuit 21 and multiple charging control circuits 22. The input side of each charging control circuit 22 is electrically connected to the main input circuit 21, and the output side of each charging control circuit 22 is connected to each charging connector 3, allowing each charging connector 3 to charge simultaneously.

[0035] This utility model relates to a multi-unit mobile phone charger that can charge multiple mobile phones simultaneously. Specifically, when multiple mobile phones need to be charged at the same time, each mobile phone is placed in the placement slot 41 of a mobile phone holder 4, and the mobile phone is connected to the charging connector 3 in the placement slot 41 of the mobile phone holder 4. The charging control circuits 22 of the charging circuit board 2 are respectively connected to each charging connector 3, ensuring that each charging connector 3 can charge simultaneously. The mobile phone holder 4 is detachable and fits into the charging box 1, so that the appropriate mobile phone holder 4 can be selected according to different sizes of mobile phones to ensure stable placement of the mobile phones.

[0036] In an embodiment of this utility model, the charging box 1 may include a box cover 101 and a box base 102 connected vertically, and the box cover 101 and the box base 102 may be fastened by screws; so as to install the charging circuit board 2 and the charging connector 3.

[0037] In an embodiment of this utility model, the upper side of the charging box 1 is provided with multiple slots 11, and each phone holder 4 is respectively fitted into each slot 11, making it very convenient to assemble and disassemble the phone holder 4. The phone holder 4 may be provided with a retaining edge 42 that abuts against the periphery of the slot 11 to ensure that the phone holder 4 is stably fitted into the charging box 1.

[0038] In an embodiment of this utility model, the bottom side of the charging box 1 is provided with a recessed power groove 12 and a wire passage groove 13 communicating with the power groove 12. The side of the power groove 12 is fitted with a power interface 5. The power interface 5 is connected to the input side of the total input circuit 21 of the charging circuit board 2 through a wiring 51. The power interface 5 can be connected to an external power adapter through a charging cable passing through the wire passage groove 13. The power groove 12 is located on the bottom side of the charging box 1 and the power interface 5 is located on the side of the power groove 12. In this way, the connection point between the charging cable and the power interface 5 is located on the lower side of the charging box 1, avoiding the connection point between the charging cable and the power interface 5 being exposed and interfering with other devices. The power interface 5 can be a DC interface.

[0039] In an embodiment of this utility model, the bottom side of the placement groove 41 of the mobile phone holder 4 forms an inclined abutment surface 411 for the bottom of the mobile phone to abut against; the mobile phone holder 4 is also provided with an upwardly protruding and inclined placement plate 43 for the middle and upper parts of the mobile phone to lean against.

[0040] In an embodiment of this utility model, the bottom side of the placement slot 41 of the mobile phone holder 4 is provided with a drainage hole 412; the charging box 1 is provided with a plurality of drainage channels 14 that communicate with the drainage holes 412 of each mobile phone holder 4, and the bottom side of the charging box 1 forms a water outlet hole 15 that communicates with each drainage channel 14; when water accidentally enters the placement slot 41 of the mobile phone holder 4, the water flows downward along the drainage hole 412, the drainage channel 14 and the water outlet hole 15, avoiding water accumulation in the placement slot 41 and affecting the charging connector 3 and the mobile phone; the charging circuit board 2 is suspended inside the charging box 1 to avoid the charging circuit board 2 coming into contact with the water flow, and the charging box 1 is provided with a plurality of support columns 16 to support the charging circuit board 2 so that the charging circuit board 2 is suspended, and the charging circuit board 2 can be provided with a clearance opening 201 corresponding to each drainage channel 14.

[0041] In this embodiment of the utility model, the charging connector 3 can be fixedly fitted to the connector seat 6. The connector seat 6 is hinged to the charging box 1, and a reset torsion spring 61 is fitted between the connector seat 6 and the charging box 1. The bottom side of the placement groove 41 of the mobile phone holder 4 has an opening 413 for the charging connector 3 to move. The charging connector 3 is connected to the output side of the charging control circuit 22 through the ribbon cable 31. This arrangement allows the charging connector 3 to move, thereby facilitating the connection of the mobile phone's charging port to the charging connector 3. The charging connector 3 can be a Type-C connector seat 6.

[0042] In an embodiment of this utility model, the charging control circuit 22 of the charging circuit board 2 has an input module 221, a DC-DC conversion module 222, and an output module 223 connected in sequence. Since the DC-DC conversion module 222 is prone to generating interference signals that interfere with the mobile phone, the charging circuit board 2 can be equipped with multiple shielding covers 7. Each shielding cover 7 covers the DC-DC conversion module 222 of each charging control circuit 22 to prevent the interference signals of the DC-DC conversion module 222 from interfering with the mobile phone. In addition, the DC-DC conversion module 222 of each charging control circuit 22 can be located on the side of the charging circuit board 2 away from the mobile phone holder 4, and the side of the charging circuit board 2 close to the mobile phone holder 4 can be provided with a grounded shielding layer (not shown), which can also effectively prevent the interference signals of the DC-DC conversion module 222 from interfering with the mobile phone.

[0043] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
