Abstract

The utility model discloses a super capacitor packaged pressure releasing explosion-proof valve, belonging to the field of a super capacitor component. The liquid injection hole of a super capacitor is inwardly machined with a valve cavity, a liquid injection circular hole is arranged below the valve cavity, a cap placing hole is arranged above the valve cavity, and the middle of the valve core is a cavity body larger than the cap placing hole; and the cylinder of a rubber plug is sleeved with a gasket to form a rubber plug assembly, the rubber plug assembly is put into the cavity body from the cap placing hole, the rubber plug covers the liquid injection circular hole, the cylinder of the rubber plug is also sleeved with a pressure spring, a cap with barbs is covered on the pressure spring, and the barbs of the cap are blocked on the steps of the cavity body, such that the rubber plug presses the liquid injection circular hole to seal, when the rubber plug assembly is under the action of the pressure spring. When the internal air pressure of the super capacitor increases to a certain degree, the air pressure overcomes the pressure of the pressure spring, discharges air and releases the pressure, and the super capacitor is still sealed after the pressure releasing, thus ensuring the long-term use performance of the super capacitor, solving the problems of swelling, cracking and explosion occurred after the super capacitor is packaged; and the operation is convenient.

Description

The encapsulation of a kind of ultracapacitor rush down the pressure explosion-proof valve

Technical field

The utility model belongs to the ultracapacitor part field, the encapsulation of particularly a kind of ultracapacitor rush down the pressure explosion-proof valve.

Background technology

At present; The encapsulation of most ultracapacitors; Too high or when applying too high voltages for fear of temperature, cause air pressure inside excessive and the danger of blast all is worked into certain weak degree with shell in position; When air pressure inside acquires a certain degree the cracking and rush down pressure, thereby avoid the generation of bigger danger.Ultracapacitor behind the cracking is scrapped thereupon.Yet in practical operation; Be difficult to guarantee the precision of shell processing; The result be not leakage ahead of time be exactly pressure to a certain degree ftractureing, cause certain hidden danger to reliability of products, add ultracapacitor and in use normally, also have some gas release and its air pressure inside is constantly increased; Cause casing deformation up to cracking, significantly reduced the useful life of ultracapacitor.

Summary of the invention

The purpose of the utility model is the encapsulation to most ultracapacitors, and is too high or when applying too high voltages for fear of temperature, causes the danger of the excessive and blast of air pressure inside and on shell, processes the indent that rushes down of certain weak degree; Yet in practical operation; Be difficult to guarantee the precision of shell processing, the result be not leakage ahead of time be exactly pressure to a certain degree ftractureing, cause the deficiency of certain hidden danger to reliability of products; And the encapsulation of a kind of ultracapacitor proposed rush down the pressure explosion-proof valve; It is characterized in that, inwardly processed a valve pocket in the liquid injection hole position of ultracapacitor, is the fluid injection circular hole below this valve pocket; Be the block putting hole above, the middle part is the cavity greater than the block putting hole; On the cylinder of plug, put pad and form the plug assembly; The plug assembly is put into cavity from the block putting hole, and plug covers the fluid injection circular hole, on the cylinder of plug, overlaps compression spring again; The block of band hangnail covers on stage clip, and the hangnail of block is stuck on cavity tops bar.

Said block is placed the aperture greater than fluid injection circular hole footpath.

Said block is placed the aperture and is slidingly matched with the block external diameter.

Said cap body is gone out the 3-7 that is uniformly distributed with hangnail that turns up at Qi Bishang.

The beneficial effect of the utility model is: solved the problem that occurs bulging, cracking and blast after super capacitor encapsulates; The liquid injection hole sealing and the explosion-proof valve of giving vent to anger are united two into one, simple in structure, easy to operate.

Description of drawings

Fig. 1 presses the explosion-proof valve structural representation for rushing down.

Embodiment

What the utility model proposed the encapsulation of a kind of ultracapacitor rushes down the pressure explosion-proof valve, below in conjunction with accompanying drawing being further described the utility model.

As shown in Figure 1, inwardly processed a valve pocket 6 in the liquid injection hole position of ultracapacitor, be fluid injection circular hole 8 below this valve pocket, be block putting hole 1 above, the middle part be the cavity 9 greater than the putting hole 1 of blocking a shot; On the circumferential wall of block 2, go out 5 hangnails 4 that are uniformly distributed with that turn up; Cover Upper gasket 5 is formed the plug assembly on the cylinder of plug 7, after ultracapacitor has been annotated electrolyte, the plug assembly is put into cavity 9 from block putting hole 1; Plug 7 covers fluid injection circular hole 8, on the cylinder of plug 7, overlaps compression spring 3 again, and the block 2 of band hangnail 4 covers on stage clip 3; When block 2 was pressed into block putting hole 1, the hangnail 4 of 5 symmetrical distributions closed up the position in hangnail 4 enters cavity 9 fully along block putting hole 1; Because its inner space is bigger; 4 beginnings of the hangnail that closes up are outwards ejected and spreading, and the hangnail 4 of block 2 is stuck on cavity 9 tops bar, and block 2 can not be withdrawed from and push down stage clip 3; Plug is combined under the effect of stage clip 3, and plug 7 is pushed down fluid injection circular hole 8 and formed sealing.

When the inner air pressure of ultracapacitor increases to a certain degree; Air pressure has overcome the pressure of stage clip and has given vent to anger and rushed down pressure; Remain sealing state after rushing down pressure; Guarantee that outside gas can not get into inside, thereby can guarantee the long-term serviceability of ultracapacitor, can not occur the state of internal high pressure again.

Claims (4)

  1. Ultracapacitor encapsulation rush down the pressure explosion-proof valve, it is characterized in that, inwardly processed a valve pocket in the liquid injection hole position of ultracapacitor, be the fluid injection circular hole below this valve pocket, be the block putting hole above, the middle part be the cavity greater than the putting hole of blocking a shot; On the cylinder of plug, put pad and form the plug assembly; The plug assembly is put into cavity from the block putting hole, and plug covers the fluid injection circular hole, on the cylinder of plug, overlaps compression spring again; The block of band hangnail covers on stage clip, and the hangnail of block is stuck on cavity tops bar.
