Abstract

The present invention relates to as battery box comprising a housing and a power supply component mounted within the housing. Through holes are provided respectively on both ends of the housing to lead a wire into the housing to connect with the power supply component. The power supply includes a circuit hoard and a battery. The housing includes an upper housing body and lower housing body which are detachably connected with each other. The upper housing body and the lower housing body could be engaged with each other to form a receiving cavity to receive the power supply component. A contact is provided on the circuit board to be in communication with the battery and correspondingly, a flexible sheet is provided on the upper housing body to press the contact. The present invention further relates to a necklace provided with the said battery box.
