Abstract
The utility model provides a span bridge conjoining structure for multiple monomer lead acid storage batteries. The span bridge conjoining structure consists of a left offset pole, a right offset pole and a conductive bridge which are integrally connected, and is positioned right above positive bus bar and a negative bus bar of a storage battery; the left offset pole and the right offset pole are separated by a housing inner baffle in such a manner that a gap of 1 mm-2 mm is formed between each other; the conductive bridge is 5 mm-10 mm in thickness, and is 2 mm-3 mm away from the upper part of the housing inner baffle; and the left offset pole and the right offset pole are designed to be semi-cylindrical and perpendicular to the conductive bridge. The conjoining structure is used for connecting multiple monomer batteries, has the advantages of small internal resistance, heavy transmission current, good reliability and high production efficiency, and adapts to the development requirements of electric motor cars and novel hybrid automobiles.
Description
Technical field
The utility model relates to a kind of many monomers lead acid accumulator and strides the bridging body structure, belongs to the lead acid accumulator field.
Background technology
Along with the development of electric motor car, new hybrid automobile, lead acid accumulator has been proposed many monomers, high-power instructions for use, this just requires to connect between monomer reliable, and big current capacity is strong, has anti-preferably short circuit performance.Traditional many cells adopt strides that bridge welding connects or the through-wall welding structure by hand, and the manual welding degree of depth is inhomogeneous, and the water conservancy diversion area is little, strides bridge welding when being prone to high current charge-discharge and connects part fusing and cause battery to be scrapped.Through-wall welding connects has relatively high expectations to utmost point crowd, if the butt-joint effect is bad, the electric current of conduction can reduce, and can not guarantee reliability.Therefore higher improvement requirement has been proposed many cells structure.In the past, because battery adopts hand assembled production, many monomers conjoined structure can't realize that along with the raising of mechanization degree, many monomers can be with the fashionable dress shell, for realizing that conjoined structure provides the technical equipment guarantee now.
The utility model content
The purpose of the utility model is to overcome that existing monomer is manual strides that bridge welding connects or the weak point of through-wall welding structure, provides a kind of and connects that internal resistance is little, transmission current is big, production efficiency is high, many monomers lead acid accumulator of good reliability is striden the bridging body structure.
The technical scheme of the utility model is: many monomers lead acid accumulator is striden and is provided with left avertence pole, right avertence pole and the conducting bridge that fuses in the bridging body structure; Be positioned at accumulator positive, negative bus-bar directly over; Left and right polar biased post is separated also by the housing internal partition; Conducting bridge thickness is at 5～10mm, the 2-3mm apart from housing internal partition top.
Above-mentioned left and right polar biased post is parallel with the housing internal partition, and vertical with conducting bridge, conducting bridge is parallel with bus-bar.
Above-mentioned left and right polar biased post is half-cylindrical, and the gap of 1-2mm is arranged between the housing internal partition.
Adopt above technical scheme, many monomers lead acid accumulator is striden the inherent defect that the bridging body structure has overcome traditional storage battery monomer connection employing manual welding or through-wall welding structure, and the monomer that is used for many cells connects; The water conservancy diversion area of conduction current between monomer is increased more than 2 times than former cross-over connection weldering or through-wall welding, connect internal resistance and reduce 1/3～1/2, transmission current is than original big 2 times; And this structure does not have distortion; Entire cell is once assembled completion, is applicable to mechanization production, enhances productivity.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As shown in the figure, many monomers lead acid accumulator is striden in the bridging body structure, and left avertence pole 1 and conducting bridge 3, right avertence pole 4 are conjoined structure, and left avertence pole and right avertence pole are separated by housing internal partition 2, leave the 2mm space.Semi-cylindrical left and right polar biased post is parallel with the housing internal partition; Vertical with conducting bridge, conducting bridge and left bus-bar 8, right bus-bar 5 are parallel, the thick 6mm of conducting bridge; Apart from internal partition 2 top 3mm; Left avertence pole and left bus-bar 8 and left utmost point crowd 7 weld together, and right avertence pole and right bus-bar 5 and right utmost point crowd 6 weld together, and realize the transmission of electric current.The utility model is compared with traditional hand welding or through-wall welding structure, has reduced once welding, has increased connection reliability, has improved production efficiency, and the area of conduction current increases 2 times, can bear the 1800A electric current more than 5 minutes.
Claims (3)
1. the monomer lead acid accumulator is striden the bridging body structure more than one kind; It is characterized in that being provided with in this conjoined structure the left avertence pole, right avertence pole and the conducting bridge that fuse; Conjoined structure be positioned at accumulator positive, negative bus-bar directly over; Left and right polar biased post is separated by the housing internal partition, and conducting bridge thickness is at 5～10mm, the 2-3mm apart from housing internal partition top.
