Problems solved by technology
[0005] When using the flashlight designed with the above two battery packs, it is inevitable to use the shell of the flashlight to conduct electricity, but the way the shell conducts electricity is easy to cause poor contact, for example, if the shell is rusted, the flashlight will not work normally, thus greatly reducing the power of the flashlight. service life

Embodiment Construction
[0026] Such as image 3 As shown, in the packaging schematic diagram of the first embodiment of the battery pack of the present invention, the battery includes a battery cell 10, and the battery cell 10 includes an upper end surface 101 and a lower end surface 102, and the upper end surface 101 is the battery cell. The positive pole, the lower end surface 102 is the negative pole of the battery cell, and the battery pack also includes a first electric board 20 and a second electric board 30, the first electric board 20 and the second electric board 30 are double-sided circuit boards respectively, and the second electric board 20 is a double-sided circuit board. A first protection circuit (not shown) is integrated on one side of an electric board 20 close to the battery cell 10, and the other side is provided with a first conductive terminal 201, a second conductive terminal 202, and a third conductive terminal 203. In this embodiment Among them, the first conductive terminal 2...

The invention relates to a battery pack and a flashlight using the battery pack, the battery pack comprises a battery cell, a first electrical plate arranged at a positive electrode of the battery cell and a second electrical plate arranged at a negative electrode of the battery cell, wherein the first electrical plate comprises a first conductive terminal, a second conductive terminal and a third conductive terminal, the second electrical plate comprises a fourth conductive terminal, a fifth conductive terminal and a sixth conductive terminal, the first conductive terminal and the fourth conductive terminal are respectively connected with the positive electrode of the battery cell, the second conductive terminal and the fifth conductive terminal are respectively connected with the negative electrode of the battery cell, and the third conductive terminal is electrically connected with the sixth conductive terminal. The implementation of the battery pack can realize that when the flashlight is designed by using the battery pack, even a switch is arranged at the tail part of the flashlight, a third circuit can be used for replacing a housing of the flashlight for electric conduction due to the fact that the two electrical plates in the battery pack respectively comprise three conductive terminals, thereby prolonging the service life of the flashlight.
Description
technical field [0001] The invention relates to a battery pack and also relates to a flashlight using the battery pack. Background technique [0002] A battery pack is a battery that packs battery cells and protective circuit packaging materials into one. The battery cells have positive and negative poles. The battery cells commonly used in flashlights are cylindrical, with one end being the positive pole and the other end being the negative pole. [0003] Figure 1A It is a schematic diagram of the packaging of the battery pack in the prior art. The packaging of the battery pack is simply to add a protection board containing a protection circuit. Each end of the battery has only one electrode, such as Figure 1A As shown, the upper end of the battery pack is the positive pole, and the lower end is the negative pole. Figure 1B is to use Figure 1A The logic diagram of the flashlight designed by the battery in , the positive pole of the battery is connected to one end of the...
