[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a travel charger, the charger comprising:

[0029] The housing assembly 100 has an expansion port 111 and a plurality of USB ports 131 on its side.

[0030] A charging circuit board 200 is fixedly connected inside the housing assembly 100. The charging circuit board 200 is provided with a plurality of USB charging heads 211, and the USB charging heads 211 are located at the USB port 131.

[0031] The plug contact 300 is fixedly connected to the charging circuit board 200 and passes through the side of the housing assembly 100 opposite to the expansion socket 111.

[0032] An expansion socket contact 400 is fixedly connected to the charging circuit board 200. The expansion socket contact 400 is located at the expansion socket 111. The plug contact 300 and the expansion socket contact 400 are electrically connected. The plug contact 300 located on different chargers can be inserted into the expansion socket contact 400.

[0033] In this embodiment, when a user charges a device, the plug contact 300 is inserted into the socket. The user can then insert a USB charging cable into the USB charging head 211 to charge smart devices such as mobile phones and tablets. When the user's device has a three-prong or two-prong plug, such as a laptop, the user can insert it into the expansion port contact 400. At the same time, different chargers can be connected in series through the plug contact 300 and the expansion port contact 400 to expand multiple USB charging devices.

[0034] The travel charger disclosed in this embodiment of the utility model, by setting up a plug contact 300, an expansion port contact 400 and a charging circuit board 200, enables one charger to charge multiple USB-enabled devices. At the same time, it can also charge devices that use plugs, allowing users to occupy a port while still having access to a single, identical port. Furthermore, multiple different chargers can be connected in series through the plug contact 300 and the expansion port contact 400.

[0035] Specifically, in this embodiment, the housing assembly 100 includes a cover plate 110, an upper housing 120, and a bottom cover 130. The expansion socket 111 is disposed on the cover plate 110. The cover plate 110 is U-shaped, the upper housing 120 is L-shaped, and the bottom cover 130 is flat. The cover plate 110, the upper housing 120, and the bottom cover 130 are connected by a snap-fit ​​structure. At the same time, the cover plate 110, the upper housing 120, and the bottom cover 130 form a closed housing structure.

[0036] In this embodiment, the charging circuit board 200 further includes a USB charging board 210, and the USB charging head 211 is located on the USB charging board 210. The USB charging board 210 and the charging circuit board 200 are electrically connected. The USB charging head 211 and the charging circuit board 200 are arranged vertically. The charging circuit board 200 and the USB charging board 210 are connected by a snap-fit. This arrangement can reduce the size of the charger. At the same time, the USB charging head 211 and the expansion socket 111 are not on the same side, so the use of USB is not affected when the charger is connected in series.

[0037] In a preferred embodiment of this invention, the USB charging board 210 is further provided with a light-emitting element 212, which is an LED light bead and is used to display the charging status.

[0038] The charging circuit board 200 is provided with a charging circuit, which is a prior art technology. In this embodiment, the charging circuit is a gallium nitride fast charging circuit, and the charging current can output charging power of 5V / 9V / 12V / 20V-3A, 4.5V-5A, 5V-4.5A and 20V-3.25A.

[0039] Preferably, the USB charging head 211 includes three output ports: one black plug-in USB-A with a rated output of 5V-1A; one orange plug-in USB-A with a rated output of 5V / 9V / 12V / 20V-3A; 4.5V-5A; 5V-4.5A; and two orange plug-in USB-C ports with outputs of 5V / 9V / 12V / 15V-3A and 20V-3.25A.

[0040] The plug contact 300 can be a US standard plug or a Chinese standard plug. The expansion socket contact 400 is a contact structure corresponding to the plug contact 300. Both the plug contact 300 and the expansion socket contact 400 are fixedly connected to the plug contact 300 by soldering.

[0041] As a preferred embodiment of this invention, a protective component 500 is further provided inside the housing assembly 100. The protective component 500 is fixed to the charging circuit board 200, and the protective component 500 is a socket anti-electric shock structure in the prior art.

[0042] Example 2

[0043] In another embodiment of this utility model, the difference between this embodiment and embodiment 1 is that the charger further includes a two-hole plug connecting wire 600, which is connected to a plug to extend the usage distance, and the two-hole plug connecting wire 600 is electrically connected to the charging circuit board 200.

[0044] In this embodiment, the plug contact 300 and the two-hole plug connecting line 600 can be set simultaneously or one of them can be set, that is, the two-hole plug connecting line 600 is not set after the plug contact 300 is set.

[0045] In this embodiment, the plug contact 300 and the two-hole plug connecting line 600 can be of the same or different plug types. Preferably, the plug contact 300 and the two-hole plug connecting line 600 have different insertion types, such as one being a two-hole plug and the other being a three-hole plug.
