The invention relates to a power
cell module connecting structure method. A power
cell module is composed of a plurality of single
cell groups, the adjacent power cell modules are connected through a connecting structure, the connecting structure comprises a PCB (
printed circuit board), and the PCB plate is provided with more than one connector; the connector comprises a
metal shell the two ends of which are communicated, the shell is internally provided with a spring piece, and a support ring is arranged between the spring piece and the inner wall of the shell and is used for fixing the spring piece and the shell; the PCB plate is provided with through holes, the shell of the connector is electrically connected with the PCB plate, and connecting holes are formed in the connector; and the contact pins of each single cell in a power cell module on the two sides of the PCB are inserted into the connecting holes of the corresponding connector, the contact pins are kept to be electrically connected with a spring piece in the connector, and the
monomer cells in the adjacent power cell modules are electrically connected through the connector. According to the invention, the connector is used for replacing a bolted connection, the contact pins and the connector are elastically connected, and the structure can not generate a loose phenomenon because of vibration.
