In another embodiment of the present invention, the separator 41 is a whole, and the separator 41 is formed with a through hole. The separator 41 divides the battery compartment 40 into two parts, namely a first battery compartment 43 and a second battery compartment 44, the first battery compartment 43 is used to accommodate the main battery 20, and the second battery compartment 44 is used to accommodate the Spare battery 30.

Two recesses, ie, a first recess 13 and a second recess 14 , are respectively provided at two laterally extending edges of the battery compartment 40 . The two recesses 13 , 14 allow the user's fingers to partially penetrate to exert force on the main battery 20 and the spare battery 30 to take out the main battery 20 and the spare battery 30 .

The circuit board 50 is located at the bottom of the battery compartment 40, and it is provided with a plurality of electrical connectors 60, each electrical connector 60 is movably connected to the circuit board 50, and the battery connected to the electrical connector 60 provides the electronic Device 1 is powered. Each electrical connector 60 includes a first end 61 and a second end 62, the first end 61 is used to pass through the back of the backup battery 30 to contact the main battery 20 to establish an electrical connection, and the second end 62 is used for Make contact with the backup battery 30 to establish an electrical connection. Each electrical connector 60 is substantially cylindrical. In this embodiment, the second end 62 protrudes from a protrusion 621 , and the protrusion 621 has a slope corresponding to the electrode 31 of the backup battery 30 . The electrical connector 60 is made of one or more metal materials selected from copper, aluminum and silver.

In this embodiment, the circuit board 50 is further provided with a protruding portion 51 , and the protruding portion 51 is located in the second battery compartment 44 . After assembly, the cavity 32 of the spare battery 30 fits with the protruding portion 51 , and the cavity 32 accommodates the protruding portion 51 and the spare battery 30 is located on the protruding portion 51 . The first end 61 of the electrical connector 60 passes through the protrusion 51 and then passes through the opening 42 of the separator 41, so the first end and the second end 61, 62 of the electrical connector 60 are all exposed. on the protruding portion 51 . In this embodiment, the height of the second end 62 of the electrical connector 60 is the same as that of the main body 10 .

Please refer to FIG. 4 together. When the main battery 20 is inserted into the first battery compartment 43, the electrical connector 60 is pushed to a predetermined position so that the second end 62 presses the elastic connecting portion 12 to establish an electrical connection. , at this time, the first end 61 is in contact with the main battery 20, and the second end 62 is separated from the backup battery 30, that is, the electrode 21 of the main battery 20 is crimped to the first end 61 of the electrical connector 60 The first end 61 of the electrical connector 60 is electrically connected to the main battery 20 and the electrical connector 60 is connected to the circuit board 50 , so the main battery 20 supplies power to the electronic device 1 .
