In other embodiments, a first charging interface 6 is disposed on the circuit board 2 and the second wiring terminal 21 , and first charging connectors 7 that cooperate with the first charging interface 6 are disposed at both ends of the first charging cable 4 .

[0040] Exemplarily, the housing 1 includes a main housing 11 and a bottom housing 12. The housing 1 may be rectangular in shape to avoid rolling on the placement surface, or may be other shapes such as a triangle. The bottom housing 12 is detachably connected to the main housing 11. After disassembling the bottom housing 12, the telescopic body 3, the power module 8, and the output module 19 can be taken out, which can facilitate the maintenance of the components in the power strip. The power plug 18 is electrically connected to the circuit board 2 and the output module 19 through the power cord running through the bottom housing 12. The power plug 18 is used to be plugged into an external power supply to supply power to the circuit board 2 and the output module 19.

The neutral pin is connected to the neutral terminal of the mains power supply, the live pin is connected to the live terminal of the mains power supply, and the ground pin is connected to the ground terminal of the mains power supply. A wire stopper is also provided on the outside of the bottom housing 12. The wire stopper is used to eliminate the stress of the power cord and prevent the core wire of the power cord from breaking at the connection with the housing 1.

[0041] Further, the circuit board 2 is arranged on the power module 8, and the power module 8 is electrically connected to the external power supply and the circuit board 2 respectively. The circuit board 2 is provided with a first charging interface 6 and a second charging interface 9, and the second charging interface 9 is a female port. The power module 8 is used to convert the voltage of the external power supply into the voltage required by each interface provided on the circuit board 2. Among them, the second charging interface 9 is vertically connected to the circuit board 2 and passes through the housing 1, and is used to charge the user's mobile device. The number of the second charging interface 9 can be one or more, and the first charging interface and the second charging interface 9 can be a Type-C (Universal Serial Bus Type-C, Type-C) interface or a USB (Universal Serial Bus, USB) interface or other commonly used charging interfaces, such as a Lightning interface. The first charging interface 6 is located in the housing 1 and faces the telescopic body 3, so as to facilitate connection with the first charging connector 7. It should be noted that the first charging connector 7 matches the model of the first charging interface 6. For example, when the first charging interface 6 is Type-C, the first charging connector 7 is a Type-C connector.

[0042] For example, Figure 3As shown, the telescopic body 3 includes a winding member 31, a sub-shell 32 and a conductive component 33. The sub-shell 32 is fixed in the shell 1, the winding member 31 is rotatably connected in the sub-shell 32, the second charging cable 5 is wound on the winding member 31, and the conductive component 33 is electrically connected to the first charging cable 4 and the second charging cable 5 respectively. Specifically, the sub-shell 32 is rectangular, and a fixed column and an elastic member (such as a spring and a spring) are provided in the sub-shell 32. The winding member 31 is connected to the fixed column to rotate around the fixed column. The second charging cable 5 is wound on the winding member 31. When the user pulls the second charging cable 5, the winding member 31 is driven to rotate in a first direction (such as clockwise) and compress the elastic member. When the user stops pulling the second charging cable 5, the elastic member drives the winding member 31 to rotate in a direction opposite to the first direction (such as counterclockwise) so that the second charging cable 5 is retracted into the winding member 31.

[0043] Further, such as Figure 3 and Figure 4 As shown, the conductive component 33 includes a first conductive sheet 331 and a second conductive sheet 332, and the second terminal 21 is located on the side of the second conductive sheet 332 facing the first charging interface 6. The second conductive sheet 332 is connected to the sub-shell 32, the first conductive sheet 331 is connected to the winding member 31, and rotates with the winding member 31, the side of the second conductive sheet 332 facing the charging interface is electrically connected to the second charging cable 5, and the side facing the first conductive sheet 331 is provided with a contact surface 14.

Specifically, the shape of the contact surface 14 disposed on the side facing the first conductive sheet 331 can be circular, or can be an arc or other shapes, as long as the convex contact 13 on the first conductive sheet 331 maintains electrical connection with the contact surface 14 on the second conductive sheet 332 during the rotation process. In a specific embodiment, the contact surface 14 disposed on the second conductive sheet 332 is plated with a metal conductive coating, such as copper, nickel, aluminum, and chromium coating, and the convex contact 13 disposed on the first conductive sheet 331 is a metal contact, such as copper, nickel, aluminum, and chromium contact.

For example, when the shape of the first charging cable 4 is flat, the shape of the cable tie hole 16 is also flat. The first charging cable 4 passes through the housing 1 through the cable tie hole 16 in the cable tie 15, and the end of the first charging cable 4 outside the housing 1 is provided with a second charging connector 17, which is a male port. The second charging connector 17 matches the model of the first charging connector 7. For example, when the first charging connector 7 is a Type-C connector, the second charging connector 17 is also a Type-C connector. The cross-sectional area of ​​the cable tie hole 16 is larger than the cross-sectional area of ​​the first charging cable 4 and smaller than the cross-sectional area of ​​the second charging connector 17, so as to block the second charging connector 17 outside the housing 1, and prevent the second charging connector 17 from shrinking into the telescopic body 3 following the third charging cable, so as to facilitate the use of the third interface. In other embodiments, the cable tie 15 is provided on the housing 1.

[0045] In a specific embodiment, at least one output module 19 is also included.

The first electrode sheet 191, the second electrode sheet 192 and the third electrode sheet 193 do not contact each other to avoid short circuit. The first socket 194 and the second socket 195 are both dual-purpose sockets, which are sockets that can be disassembled into two-hole plugs and three-hole plugs, and the third socket 196 is a two-hole socket. The output module 19 also includes an upper shell 1 and a lower shell 1 that are interlocked. The materials of the upper shell 1 and the lower shell 1 are insulating materials. The first electrode sheet 191, the second electrode sheet 192 and the third electrode sheet 193 are all arranged in the space formed by the upper shell 1 and the lower shell 1. Among them, the third electrode sheet 193 is located in the upper shell 1, and the connection end of the third electrode sheet 193 and the ground wire is located in the hollow part of the upper shell 1, and the connection end of the first electrode sheet 191 and the live wire of the external power supply is located below the lower shell.

[0046] In a specific embodiment, Figure 5 As shown, at least one of the first socket 194 , the second socket 195 and the third socket 196 is provided with a safety door 20 for preventing electric shock.
