Description
Technical field
The utility model relates to lithium ion battery, particularly a kind of lithium battery cap.
Background technology
Lithium battery is as rechargeable battery product of new generation and traditional lead-acid battery, NI-G, Ni-MH battery compare have the voltage height, energy density is large, have extended cycle life, memory-less effect and the characteristics such as pollution-free, it is that energy density is the highest in all secondary cells, the battery that cycle life is the longest.Lithium ion battery has just surmounted rapidly other secondary cell products such as Ni-MH battery, NI-G, lead-acid battery within the short more than ten years, can be widely used in the power station mobile phone, notebook computer, digital camera, electric motor car, electric tool, solar power generation, wind power generation, poultry.
Plastic lithium-ion battery can solve Insulation Problems in the battery pack connection in series-parallel process and the technical security problem in the high-pressure type battery combination process, but the composite engineering plastics that adopts at present can't satisfy Production requirement in welding method and effect, and the batch production of plastic battery is produced and also just stopped at present theory stage.Welding is main adopts hot plate welding, ultrasonic bonding, because plastics shrink problem, causes in welding process the commissure resistance to compression inadequate, and the later stage is prone to the breach phenomenon.Original technology also is added with the fillers such as glass fibre, asbestos in plastics, these fillers have not only strengthened the difficulty of welding, also cause the little seepage of battery later stage inside battery liquid.
The utility model content
The purpose of this utility model is the defects for prior art, and a kind of lithium battery cap is provided.
For solving the defects of prior art, technical scheme to be solved in the utility model is: a kind of lithium battery cap, comprise a cap body, described cap body has upper surface and lower surface, described upper surface one end is provided with anodal mount pad, the other end of described upper surface is provided with the negative pole mount pad, the position of the corresponding described anodal mount pad of described lower surface is provided with cathode contact, the position of the corresponding described negative pole mount pad of described lower surface is provided with cathode contact, described lower surface edge is provided with the first groove, and described the first groove inward flange extends outward a flange.
As a kind of improvement of the utility model lithium battery cap, described anodal mount pad and described negative pole mount pad middle part are respectively equipped with the second groove.
As a kind of improvement of the utility model lithium battery cap, be provided with a counterbore between described anodal mount pad and the described negative pole mount pad.
As a kind of improvement of the utility model lithium battery cap, described cap body is plastic rubber component.
Compared with prior art, the utility model has the advantages that: the utility model adopts plastic member to make the cap body, advantage with airtight intensity height and long service life after resistance to acids and bases, corrosion resistance, the welding, and adopt the first groove to be connected with li battery shell with flange, then weld, prevent solution leakage; The utility model is simple in structure, and crushing resistance is strong.

Fig. 2 is the utility model reverse side structure chart.
Embodiment
Below just with reference to the accompanying drawings the utility model is further described.
As depicted in figs. 1 and 2, a kind of lithium battery cap, comprise a cap body 1, cap body 1 has upper surface and lower surface, and upper surface one end is provided with anodal mount pad 2, and the other end of upper surface is provided with negative pole mount pad 3, the position of the corresponding anodal mount pad 2 of lower surface is provided with cathode contact 4, the position of the corresponding negative pole mount pad 3 of lower surface is provided with cathode contact 5, and lower surface edge is provided with the first groove 6, the first grooves 6 inward flanges and extends outward a flange 7.
Wherein, anodal mount pad 2 and negative pole mount pad 3 middle parts are respectively equipped with the second groove 8.Be respectively applied to anode interface and the negative pole interface of plug-in mounting lithium battery.
Be provided with a counterbore 9 between anodal mount pad 2 and the negative pole mount pad 3.Be convenient to be connected with the shell of lithium battery, be convenient to dismounting.
The cap body 1 that the utility model adopts is plastic rubber component.The cap body 1 that plastic rubber component is made has the advantage of airtight intensity height and long service life after resistance to acids and bases, corrosion resistance, the welding.
Need to prove, the according to the above description announcement of book and instruction, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model equivalent modifications more of the present utility model and change.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
