11 outer rings
12 inner rings
2 skeletons
Embodiment
In order more clearly to understand technology contents of the present utility model, especially exemplified by following examples, describe in detail.
Refer to Fig. 1 and Fig. 2, dicyclo sealing ring for batteries of electric automobile bag, comprise sealing ring main body 1, one end face of sealing circle main body 1 is against the outer end cap of circuit closer seat, the other end of sealing circle main body 1 is against the outer end cap of circuit closer plug, and the coupling part of circuit closer seat and circuit closer plug separates with the external world by sealing ring main body 1, and sealing ring main body 1 comprises outer ring 11 and inner ring 12, and one end fixed card of sealing ring main body 1 is located in skeleton 2.
The cross section of sealing ring main body 1 is trapezoidal, first end outer ring 11 and the radial distance between inner ring 12 in sealing circle main body 1 are less than at the second end outer ring 11 of sealing circle main body 1 and the radial distance between inner ring 12, the cross section of skeleton 2 is trapezoidal, the width of the openend of this skeleton 2 is less than the width of these skeleton 2 blind ends, skeleton 2 matches with the second end of sealing ring 1, the second end of sealing circle 1 is sheathed in this skeleton 2, skeleton 2 is metallic framework, outer ring 11 and inner ring 12 are integrated setting, and sealing ring main body 1 is body of rubber.
Dicyclo sealing ring is a H shape, when sealing, forms inside and outside twice linear sealing, and sealing property is more reliable, and skeleton 2 is stainless steel manufacture, and outer little interior large, sealing ring main body 1 snaps in skeleton 2, can not come off, and also can change easily sealing ring simultaneously.Also the decrement of having controlled sealing ring main body 1 is no more than limiting value simultaneously, when sealing ring main body 1 is pressed on sealing plane, two sealing rings are to internal modification, even if power brick amount of movement is excessive, after sealing ring main body 1 deflection is excessive, the limit of skeleton 2 is against on sealing surface, and not redeformation of sealing ring.While being arranged on the dicyclo sealing ring work on circuit closer plug, the dicyclo on sealing ring in main body 1 is close on circuit closer seat sealing plane, forms twice linear sealing, ensures that water, dust etc. can not enter voltage contact area.After sealing ring main body is compressed by design decrement, even if lost efficacy because a variety of causes causes outer shroud, still have interior ring sealing, the design is that circuit closer has increased sealingly secure coefficient, and the decrement that also can control sealing ring main body 1 is no more than design load.
