Abstract
The utility model is related to the double electrolyte filling hole structures of middle rivet, including negative lug, cover plate, core, shell, positive pole ear and insulation spacer；The negative lug is fixed on the lower end of cover plate by insulation spacer；The positive pole ear is fixed on the lower end of cover plate；The negative lug is fixedly connected with core with the lower end of positive pole ear；The core is located at the inside of shell；The cover plate is fixedly connected with shell；The cover plate is provided with liquid injection hole；The liquid injection hole is provided with two, and is symmetrical arranged；In this, the double electrolyte filling hole structures of rivet are novel, lithium ion battery with aluminum shell is solved because of the reservoir quantity deficiency series of technical such as cause super thick, circulating battery bad, while fluid injection efficiency is improved electrolyte can also be allowed preferably to infiltrate core, soak time, improve production efficiency can be reduced.
Description
Technical field
The utility model is related to cell art, the double electrolyte filling hole structures of specially middle rivet.
Background technology
Battery of mobile phone is the energy storage instrument for providing electric power for mobile phone, and what battery of mobile phone was general is lithium battery and ni-mh electricity
Pond." mAh " is the unit of battery capacity, and Chinese is MAH.
With the increasingly extensive use of the digital products such as mobile phone, to lithium ion battery shape and performance requirement increasingly
Height, generous high model are continued to bring out, the single liquid injection hole of existing aluminum-shell battery, and under fluid injection time length, liquid is slow, have a strong impact on production effect
Rate.
Utility model content
The purpose of this utility model is the double electrolyte filling hole structures of rivet in offer, and it can effectively solve the problem that in background technology and deposits
Problem.
For achieving the above object, the utility model provides following technical scheme：The double electrolyte filling hole structures of middle rivet, including negative pole
Lug, cover plate, core, shell, positive pole ear and insulation spacer；The negative lug is fixed under cover plate by insulation spacer
End；The positive pole ear is fixed on the lower end of cover plate；The negative lug is fixedly connected with core with the lower end of positive pole ear；
The core is located at the inside of shell；The cover plate is fixedly connected with shell；The cover plate is provided with liquid injection hole；The liquid injection hole sets
There are two, and be symmetrical arranged.
Further, the side of the centre distance cover plate of the liquid injection hole is 3.3mm.
Further, the aperture of the liquid injection hole is 1.2 ± 0.1mm.
Compared with prior art, the beneficial effects of the utility model are：In this, the double electrolyte filling hole structures of rivet are novel, solution
Lithium ion battery with aluminum shell determine because of the reservoir quantity deficiency series of technical such as cause super thick, circulating battery bad, has improved note
Electrolyte can also be allowed while liquid efficiency preferably to infiltrate core, soak time, improve production efficiency can be reduced.

The all other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-4 are referred to, the utility model provides a kind of technical scheme：The double electrolyte filling hole structures of middle rivet, including negative pole pole
Ear 1, cover plate 2, core 3, shell 4, positive pole ear 5 and insulation spacer 6；The negative lug 1 is fixed on lid by insulation spacer 6
The lower end of plate 2；The positive pole ear 5 is fixed on the lower end of cover plate 2；The lower end of the negative lug 1 and positive pole ear 5 with volume
Core 3 is fixedly connected；The core 3 is located at the inside of shell 4；The cover plate 2 is fixedly connected with shell 4；The cover plate 2 is provided with note
Fluid apertures a；The liquid injection hole a is provided with two, and is symmetrical arranged；The side of the centre distance cover plate 2 of the liquid injection hole a is 3.3mm；
The aperture of the liquid injection hole a is 1.2 ± 0.1mm.
The utility model is operationally：Cover plate 2 is provided with two liquid injection hole a, by two liquid injection hole a, while toward shell 4
Interior injection electrolyte, improves the fluid injection time, shortens soak time, while allowing electrolyte more preferably to infiltrate inside battery faster, carries
The basic chemical property of high battery；Lithium ion battery with aluminum shell is solved because reservoir quantity deficiency causes super thick, circulating battery bad
Etc. series of technical, while fluid injection efficiency is improved electrolyte can also be allowed preferably to infiltrate core, can reduce activating
Time, improve production efficiency.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
