Problems solved by technology

Disposable dry batteries have disadvantages such as high cost of use and environmental protection, and Ni-MH batteries have disadvantages such as low capacity and short service time. At the same time, because they are all made of cells in series, they also exist together. If a single cell is damaged, the entire battery The shortcomings that cannot be used, that is, high risk, many unstable factors, high combined processing costs, and some shortcomings that are difficult to control in production

Abstract

The invention relates to a 9V power supply device with a circuit protecting board, mainly comprising a battery box, two lithium batteries of approximate 2.75 to 4.25V, the circuit protecting board and a box cover, wherein two positive-pole contact points and two negative-pole contact points are arranged on the circuit protecting board; the two lithium batteries of approximate 2.75 to 4.25V are installed in the battery box, and the circuit protecting board is installed on the two lithium batteries of approximate 2.75 to 4.25V; the two lithium batteries of approximate 2.75 to 4.25V are connected in series through the two positive-pole contact points and the two negative-pole contact points arranged on the circuit protecting board; the box cover is installed on the battery box and seals the two lithium batteries of approximate 2.75 to 4.25V and the circuit protecting board with the battery box; and a positive pole and a negative pole are arranged on the box cover and are respectively connected with the two positive-pole contact points and the two negative-pole contact points on the circuit protecting board.

Description

technical field [0001] The invention relates to a power supply, in particular to a 9V power supply device capable of protecting the power supply from damage in the states of overcurrent, short circuit and overcharging. Background technique [0002] At present, the common 9V power supply on the market is mainly composed of several disposable dry batteries and Ni-MH batteries connected in series. If disposable dry batteries are used in series, it is composed of six 1.5V disposable dry batteries connected in series with cells. If Ni-MH batteries are used, seven 1.2V batteries are combined in series with cells. Disposable dry batteries have disadvantages such as high cost of use and environmental protection, and Ni-MH batteries have disadvantages such as low capacity and short service time. At the same time, because they are all made of cells in series, they also exist together. If a single cell is damaged, the entire battery The shortcomings that cannot be used, that is, high...
