Further embodiment is：Above-mentioned groove terminates in the middle and upper part of cylinder with the gradual narrowed and upper end of width from the bottom to top
Mode set.
Further embodiment is：Above-mentioned groove is vertical with the base plane of pedestal.
Further embodiment also has：Above-mentioned cylinder and the material of pedestal are aluminium.
The utility model has positive effect：The shell of the welding needle type ultracapacitor of the utility model, by
Liquid injection hole on shell is set, upwardly recessed concentric plectane is set in outer casing bottom and retrospect Quick Response Code is arranged on concentric plectane
Above and in housing both sides it is symmetrical arranged the structure designs such as 2 grooves as explosion-proof valve so that using the welding needle type of the shell
Compared with prior art, shell is equipped with liquid injection hole to ultracapacitor, and liquid-injection equipment quantitative liquid-filling can be used, and impregnates note compared with tradition
Liquid is time saving and energy saving and control is more accurate；The retrospect Quick Response Code of product is arranged on energy on the upwardly recessed concentric plectane of housing bottom
It is enough effectively to avoid wearing for retrospect Quick Response Code, ensure the good trackability of product；Housing both sides are symmetrical arranged 2 groove conducts
Explosion-proof valve, the danger that can effectively prevent ultracapacitor from exploding in use due to internal pressure is excessive improve production
Product security performance.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the amplified bottom view of Fig. 1.
Reference numeral in above-mentioned attached drawing is as follows：
Cylinder 1；Pedestal 2, annular portion 21, plectane portion 22, liquid injection hole 22-1；

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
（Embodiment 1）
See Fig. 1 and Fig. 2, the shell of the welding needle type ultracapacitor of the present embodiment, mainly by cylinder 1, pedestal 2 and retrospect
Quick Response Code 3 forms.
Cylinder 1 is the hollow circular cylinder part of upper and lower end opening；Pedestal 2 is by annular portion 21, transition connection portion（Do not show in figure
Go out）With 22 one composition of plectane portion；The outer diameter of annular portion 21 is engaged with the outer diameter of cylinder 1, and annular portion 21 is by its lower end periphery
With the lower face integrally connected of cylinder 1；Plectane portion 22 is arranged on the top of annular portion 21 and passes through transition connection portion and annular portion 21
Inner circumferential upper surface integrally connected；Plectane portion 22 stretches into the lower part in cylinder 1.Plectane portion 22 is equipped with being communicated inside cylinder 1
Liquid injection hole 22-1.Cylinder 1, the annular portion 21 of pedestal 2 are identical with the center line in plectane portion 22.Pedestal 2 is in production by mold
It is stamped to form.
Cylinder 1 and pedestal 2 are equipped with the groove extended from the periphery wall of the annular portion 21 of pedestal 2 to the periphery wall of cylinder 1
4；Preferably, groove 4 is equipped with 2；2 grooves 4 compared with cylinder 1 center line symmetrical setting；2 grooves 4 are with from the bottom to top
The mode for the middle and upper part that width gradually narrows and upper end terminates in cylinder is set；Groove 4 is vertical with the base plane of pedestal 2.2 recessed
Slot 4 plays a part of explosion-proof relief as explosion-proof valve, effectively can prevent ultracapacitor from exploding when in use, principle
For：With the growth of ultracapacitor usage time, inside can generate gas, in the shell that housing 1 and pedestal 2 are formed at this time
Portion's pressure, which can become larger, to be caused shell to expand and deforms upon, since other positions of thickness ratio case body are all at 2 grooves 4
Thin, when casing internal pressure is accumulated to a certain extent, 2 grooves 4 can take the lead in cracking and discharging 1 internal pressure of housing, so as to
Realization prevents product explosion function, improves the security that product uses.
Preferred aluminium in material the present embodiment of cylinder 1 and pedestal 2, aluminium shell have thermal conductivity good, and manufacture is easy to process
And the advantages that can carrying out good heat dissipation for it in super capacitor normal operation, improve stability.
Retrospect Quick Response Code 3 is arranged on the outer end face in plectane portion 22 of pedestal 2.Due to pedestal 2 plectane portion 22 compared with
The annular portion 21 of its periphery is upward（Cylinder 1）It is recessed, thus retrospect Quick Response Code 3 substantially will not be because of external force friction when in use
And damage, so that there is reliable product back-tracing using the welding needle type ultracapacitor of the present embodiment shell.
Above example is the explanation to specific embodiment of the present utility model rather than the limitation to the utility model,
Person skilled in the relevant technique can also make various changes in the case where not departing from the spirit and scope of the utility model
It changes and changes and obtain corresponding equivalent technical solution, therefore all equivalent technical solutions should be included into this practicality newly
The scope of patent protection of type.
