Abstract
The utility model discloses a storage battery cover structure for avoiding oxidation and blackening of battery formation terminals. According to the technical scheme, the storage battery cover structure comprises a storage battery cover body, wherein positive and negative terminal mounting platforms are arranged on the storage battery cover body; a positive terminal and a negative terminal are mounted on the positive terminal mounting platform and the negative terminal mounting platform respectively; specially, a sunk groove is formed between the positive terminal mounting platform and the negative terminal mounting platform. According to the storage battery cover structure, acid liquor films cannot be communicated with each other by forming the sunk groove between the positive terminal and the negative terminal on the basis of keeping the appearance integrity of a storage battery, so that a micro-short circuit formed by acid mist films is radically avoided and the oxidation and blackening of the terminals are effectively avoided; while the oxidation and blackening of the terminals are avoided, the negative influence on the storage battery due to the oxidation of the terminals is eliminated, and the product quality is improved; especially the storage battery cover structure has more important meaning for a storage battery with short terminal center distance, such as a high-capacity maintenance-free storage battery with a 2*3 plate pack and positive and negative terminals on one side.
Description
Technical field
The utility model relates to a kind of battery technology, and in the time of particularly can avoiding battery to change into, the battery cap structure of terminal oxidation blackening, belongs to battery technology field.
Background technology
The charging modes that maintenance-free lead accumulator generally adopts battery to change into (being internalized into) is produced.---assembled battery------battery formation charging---reprocessing that pours into electrolyte that its main production process is generally: green plate manufacture.In battery formation charging process, electric energy is delivered to inside battery by positive and negative binding post, and green plate forms the positive and negative pole plate with flash-over characteristic by electrochemical reaction, and store electrical energy.Its main charging reaction is:
Negative plate: PbSO4+2e-=Pb+SO42-
Positive plate: PbSO4-2e-+2H2O=PbO2+4H++SO42-
Overall reaction: 2PbSO4+2H2O=Pb+PbO2+2H2SO4
Change into the middle and later periods, the side reaction of water decomposition can occur, generating hydrogen and oxygen, and then forming acid mist discharge battery.Under the effect of acid mist, battery terminal is easy to oxidated and dimmed.Particularly, along with acid mist is constantly discharged, accumulated, can form one deck acid mist film continuous, that can conduct electricity on battery cover surface.This conduction liquid film is communicated with after positive and negative terminal, can make plus end corrosion accelerate and blackening.After terminal oxidation blackout, can increase sheet resistance, affect the charging acceptable effect of battery, the micro-short circuit that acid mist film forms can cause energy loss.Prior art is, in last handling process, blackout terminal is carried out to sanding and polishing for the solution of this problem.This method has only adopted measure rather than the process precautionary measures of correcting terminal blackout, can not fundamentally solve adverse effect terminal blackout and that blackout causes storage battery.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of by the architecture advances to battery cap, can effectively avoid battery to change into the battery cap structure of terminal oxidation blackening.
Problem described in the utility model realizes with following technical proposals:
A kind of battery cap structure of avoiding battery to change into terminal oxidation blackening, it comprises battery cap body, battery cap body is provided with positive and negative terminal mounting platform, on positive and negative terminal mounting platform, positive and negative terminal is installed respectively, special feature is: the groove that is provided with depression between described plus end mounting platform and negative terminal mounting platform.
The above-mentioned battery cap structure of avoiding battery to change into terminal oxidation blackening, described plus end mounting platform, negative terminal mounting platform are disconnected completely by groove, form separately independently two parts.
The above-mentioned battery cap structure of avoiding battery to change into terminal oxidation blackening, described groove end face is 3-15 millimeter lower than the distance H of positive and negative terminal mounting platform end face.
The above-mentioned battery cap structure of avoiding battery to change into terminal oxidation blackening, the width L of described groove is 3-50 millimeter.
The problem that the utility model changes into the acid mist film oxidation terminal of middle generation for solution maintenance-free lead accumulator is improved the structure of battery cap.Keeping, on the basis of battery cap overall appearance, by the groove of depression is set between positive and negative terminal, acid solution film can not being interconnected, fundamentally stopping the micro-short circuit that acid mist film forms, thereby effectively avoiding terminal oxidation blackout.The utility model, when avoiding terminal oxidation blackout, has been eliminated adverse effect storage battery being caused because of terminal oxidation, is conducive to improve the quality of products.Particularly, for the little storage battery of terminal centre-to-centre spacing, such as utmost point group is all positioned at the large capacity maintenance free cell of a side with 2 * 3 structural arrangement, positive and negative binding post, have more practical significance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the confined state schematic diagram of the utility model and storage battery container.
In figure, each list of reference numerals is: 1, battery cap body, 2, negative terminal mounting platform, 3, negative terminal, 4, groove, 5, plus end, 6, plus end mounting platform, 7, storage battery container.
Embodiment
Referring to Fig. 1, the utility model comprises battery cap body 1, is provided with for assembling plus end mounting platform 6 and the negative terminal mounting platform 2 of positive and negative terminal on battery cap body, and plus end 5 and negative terminal 3 are just being arranged on respectively, on terminal mounting platform.Acid mist conductive film forms micro-short circuit between positive and negative terminal when avoiding changing into, the utility model is provided with the groove 4 of depression between plus end mounting platform 6 and negative terminal mounting platform 2, plus end mounting platform 6 and negative terminal mounting platform 2 are disconnected completely by groove 4, form separately independently two parts.Like this, make between positive and negative terminal, not have continuous level, acid solution film can not be interconnected, thereby avoid forming continuous conduction liquid film between positive and negative terminal, reach the object of prevention terminal blackout.
Still, referring to Fig. 1, different according to the specification of storage battery, the end face of groove 4 is 3-15 millimeter lower than the distance H of positive and negative terminal mounting platform end face; The width L of groove is 3-50 millimeter.
Referring to Fig. 2, this is that battery cap described in the utility model is installed to the confined state schematic diagram on storage battery container 7.
