Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the structure chart of the utility model storage battery hermetic terminal embodiment one;
Fig. 2 is the structure chart of the middle cover among Fig. 1;
Fig. 3 is the structure chart of the utility model storage battery hermetic terminal embodiment two.
Embodiment
Embodiment one
See also Fig. 1 and Fig. 2, the utility model storage battery hermetic terminal comprises middle cover 1, pole 2, sealing ring 3 and pressure ring 4.Wherein
Not only fixedly connected pole of pressure ring but also fixedly connected middle cover also compress sealing ring, thereby can prevent that pole from upwards and to the left and right moving in installation and use.In the processes that first pressure ring 41 is twisted downwards, pole can be subjected to thrust upwards, and sealing ring played the pad effect and made the junction realize tight fit can preventing that effectively pole from moving up by the tight fit mode this moment.Can to sealing ring produce downward extruding force in the processes that second pressure ring 42 is twisted downwards, can effectively stop pole upwards and left and right directions move.Simultaneously, second pressure ring 42 is pushed down first pressure ring 41, can prevent from that pole plate deformation causes the pole band first pressure ring 41 in the accumulator charging/discharging process to move up.
