1. Technical Field
The disclosure relates to an electronic device and, more particularly, to an electronic device having reserve power during battery replacement.
2. Description of the Related Art
Electronic apparatuses, such as mobile phones, run on battery power. When a battery runs low and the user decides to replace the battery with another one rather than using a charger, then the apparatus must be powered off, which may result in data loss.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the electronic device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
At least two pairs of electric joint elements 300 are fitted on the PCB 30. The elements 300 of each pair of the at least two pairs of electric joint elements 300 are aligned in parallel to each other. At least one pair of electric joint elements 300 is engaged with the battery 20. In this embodiment, the PCB 30 has two pairs of electric joint elements 300 fitted thereon. The two pairs of electric joint elements 300 include a pair of elastic slots 31 and 33, and a pair of elastic slots 32 and 34. The pair of elastic slots 31, 33 and the pair of elastic slots 32, 34 are aligned in parallel. Each elastic slot is composed of conductive material, such as copper. Two pairs of elastic slots are engaged with the battery 20.
In this embodiment, each elastic slot has a circular hollow part 310, a diameter of the hollow part of the elastic slot 31 is equal to a diameter of the hollow part the elastic slot 32, and a diameter of the hollow part of the elastic slot 33 is equal to a diameter of the hollow part of the elastic slot 34. The diameter of the hollow part of the elastic slot 31 or 32 is different from the diameter of the hollow part of the elastic slot 33 or 34. For example, the diameters of the hollow parts of the elastic slots 31, 32 are 1.5 millimeters and the diameters of the hollow parts of the elastic slots 33, 34 are 1 millimeter. In another embodiment, all the elastic slots 31, 32, 33, 34 are the same.
The battery 20 has at least two pairs of electrodes. In this embodiment, an anode 21 and a cathode 23 are adjacent to side of the battery 20, and an anode 22 and a cathode 24 are adjacent to an opposite side of the battery 20. The two pairs of electrodes are connected in parallel and provide the same voltage. Each electrode is a cylindrical protrusion. Each protrusion is composed of conductive material such as copper.
Diameters of the cylindrical protrusions of the anodes 21, 22 are equal to the diameters of the hollow parts of the elastic slots 31, 32. Diameters of the cylindrical protrusions of the cathodes 23, 24 are equal to the diameters of the hollow parts of the elastic slots 33, 34. Therefore, a user can easily distinguish the anode and the cathode of the battery 20. Each pair of the cylindrical protrusions of the anode and the cathode can be engaged with each pair of the hollow parts of the elastic slots and rotate relative to each pair of the elastic slots.
When the battery 20 is inserted into the accommodating space 40, the anode 21 of the battery 20 is engaged with the elastic slot 31 or 32 and the cathode 23 of the battery 20 is engaged with the elastic slot 33 or 34. As shown in

In another embodiment, each pair of electric joint elements of the PCB is a pair of cylindrical protrusions. Each pair of anode and cathode of the battery is a pair of elastic slots. The protrusions and the elastic slots are composed of conductive material. Each pair of the elastic slots of the battery is engaged with a corresponding pair of protrusions of the PCB.
It is understood that the disclosure may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the disclosure is not to be limited to the details given herein.
