Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help those skilled in the art to the design of the utility model, technical solution have it is more complete, accurate and
Deep understanding, and contribute to its implementation.
As shown in Figures 1 to 4, a kind of power battery cap assembly, by groups such as positive terminal 10, negative terminal 6, coping plates 4
At specially 4 both ends of coping plate are respectively equipped with positive and negative electrode post holes, and positive and negative pole upper end covers that there are one sealing ring 5, negative terminals
6 pass through plastic cement 2 on the cathode on 4 top of coping plate 4 and coping plate to be riveted with cathode riveting block 1, and it is preferably cathode that cathode, which rivets block 1,
Aluminium block is riveted, plastic cement main function is that negative terminal and coping plate are electrically insulated on cathode.Using ceramic fixing glue 3 by pole and top
Cover plate locks together, and prevents from rotating.Coping plate 3 is equipped with rotating sheet 14, and rotating sheet 14 is provided close to 6 side of negative terminal, turns over
Rotor 14 rivets block 1 by being flipped up contact cathode.Rotating sheet can be specifically welded on coping plate, plastic cement 2 is right on cathode
It answers 14 position of rotating sheet to offer hole, passes through it to be contacted with cathode riveting aluminium block when being overturn for rotating sheet, realize that circuit is connected.
When inside battery because overcharging, it is out of control etc. caused by inside battery air pressure increase so that rotating sheet is flipped up contact cathode riveting aluminium
Block, because positive terminal is also electrically connected with coping plate, leads to positive and negative anodes Electricity Federation to electrically connect coping plate and negative terminal
