Abstract
The utility model discloses a seal fixture rubber ring for formation of a square lithium ion battery, which aims at overcoming the defect of a seal fixture when a lithium ion battery is formed in the prior art. The design key point is as follows: the rubber ring is made of a flexible material, the wall thickness, the width and a conical lug boss are realized according to the optimal use characteristics, for example, the rubber ring is pre-charged when sleeved on a battery liquid injecting hole, a certain gas and pressure can be generated in an internal environment, when the internal environment generates gas to reach a certain pressure, the rubber ring upwards shrinks the depth extending into the liquid injecting hole, gas with a certain pressure is discharged from the side surface of the conical lug boss, and under the condition of no gas pressure of the internal environment, the elasticity of the rubber ring automatically sleeves the conical lug boss on the liquid injecting hole so as to prevent outside water permeating into a battery from influencing the comprehensive use performance of the battery.
Description
Technical field
The utility model relates to rectangular lithium ion battery and makes the field, relates in particular to a kind of rectangular lithium ion battery and changes into the sealing tool rubber ring.
Background technology
Along with development and the progress of society, people also constantly strengthen the consciousness of environmental protection, and lithium ion battery is representing the at present technological state of the art of development as the new green environment protection new forms of energy.Notebook computer, microcomputer, digital camera, cell phone, the development of the electronic products such as medicine equipment is all had higher requirement to battery industry.And lithium ion battery will come the formation process of active material in the activated batteries normally to use through precharge after a fluid injection is finished in assembling.
In the prior art, battery is inner in formation process can to produce gas, existing lithium ion battery changes into the frock of sealing, sometimes can not discharge the gas of battery the inside smoothly battery generation thickness is exceeded standard, and the moisture content outside making sometimes penetrates into the inside of battery, the moisture content of inside battery is exceeded standard, affected the Integrated using performance of battery, and in assembling process, process flow is more, very inconvenient during operating personnel's operation, affect production efficiency.
The utility model content
The purpose of this utility model is to overcome the deficiency of sealing tool when lithium ion battery changes in the prior art, its design main points are, rubber ring is flexible material, wall thickness, width, cone boss, elastic pulling force all adopts best handling characteristics, for example rubber ring is when entangling the battery liquid-filling mouth and carry out precharge, inner bad border can produce certain gas and air pressure, when inside produced gas to certain pressure, rubber ring can upwards be received the degree of depth of Su Shenjin liquid injection hole, allows inside have the gas of certain pressure to discharge from the cone boss side, in the situation that does not have gas pressure of internal environment, the elasticity of rubber ring can tightly be entangled liquid injection hole to cone boss automatically, has prevented that the moisture content of outside from infiltrating inside battery, and has affected the Integrated using performance of battery.
The technical solution of the utility model is:
A kind of rectangular lithium ion battery changes into the sealing tool rubber ring, comprising: rubber ring is positioned at the cone boss of rubber ring inboard.
The described cone boss that is positioned at the rubber ring inboard, what it was connected with the rubber ring inboard is the major part part, and diameter is 1.1～2mm, and the other end is little head part, and diameter is 0.3～0.8mm.
Described rubber ring is soft adjusting degree material, has the performance of elastic recovery.
Described rubber ring wall thickness is 0.1～0.8mm.
Described rubber ring width is 2～10mm.
Technique effect of the present utility model is: the inner gas that produces can not normally discharge when moisture content penetrated into inside battery and precharge when having avoided changing into sealing, and is easy to operate simple, improves serviceability.
Description of drawings
Fig. 1 is generalized section of the present utility model
Fig. 2 is axonometric drawing of the present utility model
In the drawings, 1 rubber ring, 2 Aluminum covers, 3 are positioned at the cone boss of rubber ring inboard, 4 batteries
Embodiment
As shown in Figure 1 and Figure 2, the utility model is achieved like this, rubber ring 1 has the elastic recovery material for soft adjusting degree, wall thickness is 0.3mm, width is 6mm, the one end has a cone boss, the boss diameter at butt end is 1.4mm, top diameter is 0.5mm, rubber ring 1 is enclosed within on the battery 4, and the cone boss 3 that wherein is positioned at the rubber ring inboard is filled in the liquid injection hole of battery 4, and rubber ring utilizes elastic recovery to be close to face and the battery bottom surface of Aluminum cover 2, with inside battery environment and outside air isolation, play sealing function.
Above-described only is that the utility model preferred implementation is described; be not that design of the present utility model and scope are limited, the development technique personnel are to the utility model concept, official documents and correspondence in this area; make various distortion and improvement, all belong to the utility model protection range.
