Abstract

The utility model relates to a sealing structure component for a lead-acid battery, which is provided with a battery terminal 4 and a battery cover 1, wherein, the side of the battery terminal 4 is surrounded, bonded and fixed with a vulcanized rubber sleeve 3, wherein, the periphery of which is tightly sheathed and combined with the battery cover 1, wherein, the upper part of the battery cover 1 can be externally expanded in radial direction to form a pelvic cavity-shaped space in which a sealing material layer 6 is filled. The side of the battery terminal 4 can be provided with an annular groove in which a vulcanized rubber body is filled and combined to become an annular bulge part on the inner side of the vulcanized rubber 3.

Description

Lead acid accumulator hermetically-sealed construction assembly

The utility model relates to the constitutional detail of the nonactive parts of battery, particularly relates to the storage battery hermetically-sealed construction.

Before the utility model proposes,, adopt following method usually: 1., reach the mechanical seal purpose as O type circle, rectangular loop etc. by compression soft rubber sealing ring to the sealing of electrode pile of valve-controlled sealed lead-acid accumulator; 2. directly with adhesive, pour into the purpose that the sealing position reaches the adhesive sealing as epoxy resin, polyurethane adhesive etc.; 3. the sealing position is embedded in plumbous overlapping on battery cover, again with lead cover and the welding of corresponding pole, thereby reaches the purpose that plumbous cover seals; 4. above-mentioned three kinds of derivation hermetically-sealed constructions that complement each other and form.The actual use shows that because the sealing intensity and the impact resistance of these hermetically-sealed constructions are relatively poor, its sealing effectiveness is good inadequately, and hermetically-sealed construction goes to pot under situations such as mechanical oscillation and thermal shock easily.

The purpose of this utility model is to provide sealing intensity and impact resistance height for overcoming above-mentioned defective, a kind of lead acid accumulator hermetically-sealed construction assembly of good sealing effect.

The technical solution of the utility model lead acid accumulator hermetically-sealed construction assembly is to be provided with battery electrode column and battery cover, and its special character is to enclose at battery electrode column side ring to be adhesively fixed with the vulcanized rubber cover, and the peripheral tight cover of vulcanized rubber cover is combined with battery cover.

For further increasing the intensity of hermetically-sealed construction, its top of described battery cover can radially extend out and form pelvic cavity shape space and be filled with sealing material layer in it.

Be the length that can increase battery electrode column and vulcanized rubber cover faying face longitudinal approach (this approach be sulfuric acid climb leak the approach of corrosion), can be provided with ring-shaped groove in the battery electrode column side and fill in it and be combined with the annular portions that the vulcanized rubber body becomes vulcanized rubber cover inboard along battery electrode column.

The utility model lead acid accumulator hermetically-sealed construction assembly is adhesively fixed with a vulcanized rubber cover owing to enclosing at its battery electrode column side ring, this vulcanized rubber cover has enough strong adhesive bond power and adaptation with the battery electrode column side, and the vulcanized rubber cover can have enough longitudinal lengths, make combization rubber sleeve and battery electrode column closed surface have enough longitudinal lengths, thereby can effectively stop the leakage of climbing along the battery electrode column side of sulfuric acid in the battery; Because the peripheral tight cover of vulcanized rubber cover is combined with battery cover, sulfuric acid also can not leaked through the faying face of battery cover and vulcanized rubber cover again; Also, have height toughness and impact strength because vulcanized rubber has the sufficiently high degree of cross linking, thus the sealing intensity height of the utility model lead acid accumulator hermetically-sealed construction assembly, good sealing effect, antivibration, excellent in cushion effect.

Below in conjunction with description of drawings execution mode of the present utility model.

Fig. 1 is a kind of schematic diagram of the utility model lead acid accumulator hermetically-sealed construction assembly;

Fig. 2 is the another kind of schematic diagram of the utility model lead acid accumulator hermetically-sealed construction assembly;

Fig. 3 is another schematic diagram of the utility model lead acid accumulator hermetically-sealed construction assembly.

Embodiment 1 lead acid accumulator hermetically-sealed construction assembly, referring to Fig. 1, skin with battery cover 1 and embedded copper chipware 2 is the battery electrode column 4 of terne metal, encloses at battery electrode column 4 sides ring to be adhesively fixed with vulcanized rubber cover 3, and vulcanized rubber cover 3 peripheral tight covers are combined with battery cover 1.

Battery electrode column 4 is that raw rubber is mixed with crosslinking agent with the processing that vulcanized rubber overlaps 3 assemblys, adds to the battery electrode column to be inner core and to be provided with in the cavity of external mold, heats, pressurizes, and directly forms vulcanized rubber cover 4 and combines closely and form in the battery electrode column side.

2 routine lead acid accumulator hermetically-sealed construction assemblies of embodiment; referring to Fig. 2; its battery cover 1 top radially extends out and forms pelvic cavity shape space and be filled with binder-type sealing material layer 6 in it; sealing material layer 6 bottoms are provided with rubber sheet gasket 7; be covered with protective sleeve 5 above the sealing material layer 6; vulcanized rubber overlaps 3 upper ends envelope and is embedded in sealing material layer 6 and is positioned at position, sealing material layer 6 middle and lower part, makes battery electrode column 4 have this side section of a side section and combines with sealing material layer 6.Other structures are identical with last example.

3 routine lead acid accumulator hermetically-sealed construction assemblies of embodiment, referring to Fig. 3, its battery electrode column 4 sides are provided with ring-shaped groove and fill in it and be combined with the vulcanized rubber body and become the annular portions that vulcanized rubber overlaps 3 inboards.Other structures are identical with example 2.
