SECONDARY ELECTROCHEMICAL BATTERY SEALING BODY WITH CHARGE INDICATING LAMP

摘要

Disclosed is a secondary electrochemical battery sealing body with a charge indicating lamp. The secondary electrochemical battery sealing body comprises: a cathode cap, a circuit board module and an insulating gasket. The cathode cap is located on the outermost side of the battery sealing body. The circuit board module is located on the inner side of the cathode cap and is connected to the cathode cap via a connecting member. The charge indicating lamp is arranged on the circuit board module at the position corresponding to an edge of the cathode cap. The part where the cathode cap is connected to the circuit board module is of a "C"-shaped annular structure. That is to say, a notch is formed in the edge of the cathode cap. The notch serves as a light-pervious port of the charge indicating lamp. The notch has a certain height which does not exceed the height of the cathode cap, and the position of the notch corresponds to the position of the charge indicating lamp on the circuit board module. The insulating gasket is a flexible and elastic annular insulating cushion layer, and is arranged in a gap between a battery housing, the circuit board module and the cathode cap. The insulating gasket further completely covers the light-pervious port of the charge indicating lamp to seal the cathode cap, the battery housing and the circuit board module, and the insulating gasket is made of a transparent light-transmitting material.
