Abstract
The utility model relates to a lead-acid storage battery plastic cover for preventing acid seepage, belongs to the technical field of storage batteries, and aims to solve a problem of acid seepage in a combination part between a lead-acid storage battery cover terminal and plastic. According to the technical scheme, the lead-acid battery comprises a storage battery plastic cover body and the terminal, wherein the lower part of the terminal is combined with the storage battery plastic cover body by injection molding. The lead-acid storage battery is characterized in that annular bumps and annular grooves are arranged in the place where the terminal is combined with the storage battery plastic cover body by injection molding, wherein the side of at least one annular bump is provided with a side groove. By the lead-acid storage battery, the tightening degree of wrapping the storage battery plastic cover body and the terminal is increased, the lead terminal is tightly bound to the plastic through an adhesive sticker to separate acid, so that acid seepage resulting from a gap generated by the expansion and contraction effect in the using process of storage batteries is avoided, the phenomenon that acid seepage exists during the service life of lead-acid storage batteries can be avoided, the safety of lead-acid storage batteries is improved, and the service life of the lead-acid storage battery is prolonged.
Description
Technical field
The utility model relates to a kind of battery components, prevents that particularly lead acid accumulator from moulding lid and oozing acid with the plastic coupling part of terminal, improve the safety in utilization of storage battery and the lead acid accumulator in useful life is moulded lid, belongs to the battery technology field.
Background technology
Usually, lead acid accumulator is moulded lid and is adopted the Shooting Technique manufacturing, and storage battery is moulded to cover and is provided with terminal, and terminal is to adopt Shooting Technique to be connected with parts of plastics, and the material of terminal is a lead alloy.Lead acid accumulator in use sour phenomenon can occur oozing in the position that combines with plastics of terminal, can corrode the associated components that is connected with storage battery when serious, causes storage battery shortening in useful life.For delaying the generation of above problem, general way is, increases the length that is connected of terminal and plastics, promptly prolongs and oozes sour distance; Perhaps use special seal gum, together with terminal and plastic bonding; Or increase rubber ring or rubber blanket at the plastic position of terminal and plastics.Though more than these methods can both play the effect that acid is oozed in certain prevention, all come with some shortcomings: adopt prolongation to ooze the method for sour distance, receive the limitation of battery self structure, have limiting length, otherwise will increase material and manufacturing cost; Adopt the method for fluid sealant to receive the restriction of plastic material kind, and can significantly reduce the production efficiency of storage battery; Adopt the method for sealing ring also need increase corresponding fastenings, make the structure of battery cap complicated, otherwise significantly do not hinder sour effect.
The utility model content
The utility model is used to solve the defective of prior art, provides a kind of lead acid accumulator that oozes acid that prevents simple in structure, that can reach the sour effect of good resistance to mould lid.
The alleged problem of the utility model solves with following technical proposals:
A kind of lead acid accumulator that oozes acid that prevents is moulded lid; It comprises that storage battery is moulded and covers body and terminal; Terminal bottom and storage battery are moulded and are covered the body injection moulding and combine; Special feature is: said terminal and storage battery are moulded and are covered body injection moulding binding site arrangement annular protrusion and annular groove, and wherein, the side edge of at least one annular protrusion is provided with the side groove.
The above-mentioned lead acid accumulator that oozes acid that prevents is moulded lid, is provided with non-drying glue layer at least one annular groove.
The above-mentioned lead acid accumulator that oozes acid that prevents is moulded lid, and said annular protrusion, annular groove and side groove surfaces are the polishing minute surface.
The position that the utility model combines with plastics to the lead-acid battery lid terminal is oozed sour problem and is improved, and has designed the sour effective lead acid accumulator of a kind of antiseepage and has moulded lid.The plastic position of terminal that this storage battery is moulded lid is provided with annular protrusion, annular groove and side groove; Storage battery be can increase and lid and the plastic tightness degree of terminal moulded; And at least one annular groove, be provided with rubber such as butyl rubber or elastomer to be the non-drying glue layer of carrier, terminal and plastics to be closely bonded be in the same place, play the effect that intercepts acid; Avoided storage battery in use to cause leaking acid because the effect of expanding with heat and contract with cold produces the slit; Make lead acid accumulator in the operating period, sour phenomenon do not occur oozing, improved the fail safe and the useful life of lead acid accumulator.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view (amplification) of Fig. 1;
Fig. 3 is Fig. 2 B place partial enlarged view.
The label of each parts is represented as follows in the accompanying drawing: 1, storage battery is moulded and is covered body; 2, terminal; 3, annular protrusion; 4, side groove; 5, non-drying glue layer; 6, annular groove.
Embodiment
Referring to Fig. 1, the utility model comprises that storage battery is moulded and covers body 1 and terminal 2, and terminal is a mold insert, and its underpart is adopted Shooting Technique and storage battery to mould to cover the body injection moulding and combined.
Referring to Fig. 2, Fig. 3; Mould the binding site that covers body 1 and terminal 2 and ooze acid for preventing storage battery; Said terminal 2 is moulded with storage battery and is covered the arrangement of body 1 injection moulding binding site several annular protrusions 3 and annular groove 6; The number of annular protrusion 3 and annular groove 6 is 2-6, and wherein, the side edge of at least one annular protrusion is provided with side groove 4; Being provided with rubber such as butyl rubber or elastomer at least one annular groove 6 is the non-drying glue layer 5 of carrier; Annular protrusion, annular groove and side groove surfaces adopt the polishing mirror process.Said structure makes storage battery mould lid side groove, annular protrusion, the annular groove of terminal is bundled together closely, and non-drying glue layer plays terminal and storage battery are moulded the effect that lid closely bonds simultaneously.
