Embodiment
In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and embodiment
The utility model is described in further detail.
Referring to Fig. 1, Fig. 2, the utility model provides to be covered in a kind of high leakproofness of ultracapacitor, and it includes lid master
Body 1, the upper cap body 1 extend vertically through in horizontal center position and are provided with a liquid injection hole 2, and the liquid injection hole 2 is used to inject
Electrolyte required for the ultracapacitor, there is multi-sealing structure in the liquid injection hole 2.
In the utility model, the liquid injection hole 2 includes upper hole 21 and bottom hole 22, and the upper hole 21 is positioned at described
The surface of bottom hole 22, the aperture of the upper hole 21 are more than the aperture of the bottom hole.
In specific implementation, the upper hole 21 and bottom hole 22 are circular through hole, the center line of the upper hole 21
It is located at the center line of bottom hole 22 on same vertical center line, as described upper hole 21 and bottom hole 22 are same center line
Set.
In the utility model, the multi-sealing structure having in the liquid injection hole 2 is specially：Under the bottom hole 22
Portion is inserted with pre-sealed plug 3, and the top seal of the bottom hole 22 is connected with the first permanent seal 4, and the upper hole 21 is close
Envelope is connected with the second permanent seal 5, the upper and lower ends of first permanent seal 4 respectively with second permanent seal
The top surface of 5 bottom surface and the pre-sealed plug 3 connects.
Therefore, can be permanent close by the first permanent seal 4 and second for the utility model, it is necessary to illustrate
Sealing 5, dual permanent seal is realized, and realize that a resealing acts on again by pre-sealed plug 3, finally realize triple seal
Effect, so as to having multi-sealed effect, the quality sealed to liquid injection hole is effectively ensured, the problem of avoiding the occurrence of leakage, and
Improve the product qualified rate of ultracapacitor.
In addition it is also necessary to explanation, first permanent seal 4 is due to being arranged on second permanent seal 5
Between the pre-sealed plug 3, the upper and lower ends of specially described first permanent seal 4 respectively with second permanent seal
The top surface of the bottom surface of part 5 and the pre-sealed plug 3 connects, and therefore, the upper and lower ends of first permanent seal 4 are not susceptible to
Effect of vibration to external force influences, and has good sealing property, can be obviously improved on ultracapacitor of the present utility model
The sealing of the liquid injection hole covered.
In specific implementation, second permanent seal 5 is connected by way of laser welding with the upper hole 21 sealing
It is connected together, first permanent seal 4 is connected also by the mode of laser welding with the top seal of the bottom hole 22
Together.
In specific implementation, the top of first permanent seal 4 has circular groove 40.It should be noted that set
The purpose of the groove 40 is put, is the first permanent seal 4 because during the first permanent seal 4 is pressed into liquid injection hole
Inside contraction deformation is had, if not setting groove 40, due to being interference fit, the first permanent seal 4 will quite difficult pressure
Enter into the bottom hole 22.In addition, after being pressed into the bottom hole 22, during welding, default optical image recognition can be passed through
Device identifies this groove, so as to positioning welding position.
It should be noted that in specific implementation, the quantity of the permanent seal 5 of the first permanent seal 4 and second can
To be not limited to one shown in Fig. 2, according to the needs of user, it can also be any number of, it is only necessary to each first permanent seal
Part 4 is sealed with the bottom hole 22 and each second permanent seal 5 with the upper hole 21 by modes such as laser weldings
Link together.Therefore, the utility model is in the presence of multiple permanent seals 5 of first permanent seal 4 and second,
More preferable multi-sealed effect can be realized.
In specific implementation, the permanent seal 5 of the first permanent seal 4 and second is preferably can using copper, tin, aluminium etc.
To carry out the seal made by the metal material of laser welding, there is relatively reliable sealing effectiveness.
In specific implementation, the pre-sealed plug 3 is preferably to use sealing-plug made of rubber.It should be noted that institute
With set it is pre-sealed plug 3, be because ultracapacitor fluid injection operation need exclusion of water, oxygen environment in carry out, therefore, note
Liquid operation generally exclusion of water, oxygen vacuum glove box in carry out, to ultracapacitor complete fluid injection operation after, it is also necessary to
The sealing welding operation of the liquid injection hole of super capacitor upper cover is carried out in environment outside vacuum glove box again, in order to ensure to be electrolysed
The sealing effectiveness of liquid, effectively avoid electrolyte that bad haptoreaction occurs with outside environment, can lead in vacuum glove box
Temporarily sealing is realized after inserting pre-sealed plug 3 in advance, then moves on to again in the environment outside glove box, passes through laser welding
Mode, the first permanent seal 4 and the second permanent seal 5 are subjected to Laser Welding with the bottom hole 22, upper hole 21 respectively
Connect, so as to realize permanent seal, there is multi-sealed good result.
In summary, compared with prior art, in a kind of high leakproofness of ultracapacitor provided by the utility model
Lid, it can carry out firmly, reliably sealing to the liquid injection hole on upper lid, effectively lift the sealing of liquid injection hole, avoid the occurrence of
The problem of leakage, the service life and security performance of ultracapacitor are obviously improved, is advantageous to widely popularization and application, there is weight
Big production practices meaning.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
