Explosion-proof battery supply unit of the present invention; Wherein, said first airtight container comprises and is enclosed within first, second outer intercell connector kerve of two poles respectively and is located at the medial launder between first, second intercell connector kerve that first, second intercell connector kerve structure is identical; Wherein the first intercell connector kerve is a U-lag; Inboard, U-lag two side is respectively equipped with a horizontal fin, and the outside, two side of medial launder is respectively equipped with a transverse concave groove, and two grooves are stuck on two fins.
Explosion-proof battery supply unit of the present invention, wherein, said second airtight container comprises connector kerve and card; The connector kerve comprises pole socket end and adaptor cup jointing end, and the end face of adaptor cup jointing end is provided with breach, and the breach bottom is semicircle; Inboard, adaptor cup jointing end two side is respectively equipped with a vertical fin; Card is stuck on the fin, and the width of card equates that with the width of adaptor cup jointing end it is semicircular breach that card is provided with the top.
Explosion-proof battery supply unit of the present invention wherein, is interval with two outages on the said box bottom.
Explosion-proof battery supply unit of the present invention, wherein, the sidewall of said casing is provided with ventilation hole on several, ventilation hole under several.
After adopting such scheme; Explosion-proof battery supply unit of the present invention is because hard intercell connector and two pole overcoats have first airtight container; The joint of line and pole of being flexible coupling is with second airtight container outward, and irritating in first, second airtight container has insulating cement, and the junction insulation property of therefore hard intercell connector, be flexible coupling line and two poles are better; In the combustible dust environment, avoid causing burning, blast because of adsorbing a large amount of dust.
In addition, the box bottom of explosion-proof battery supply unit of the present invention is provided with outage, and wall box is provided with ventilation hole, therefore avoids box house to assemble a large amount of battery liquid, hydrogen, strengthens the fail safe of explosion-proof battery supply unit.
