Abstract
The utility model discloses a lead-saving negative comb plate for welding a lead-acid storage battery. The lead-saving negative comb plate comprises a strip-shaped plate-shaped main comb plate body, wherein busbars are arranged on one side of the main comb plate body in the length direction; comb teeth are formed in the busbars; tooth seams are formed among the comb teeth; and the lengths of the tooth seams among the comb teeth are not the same. Compared with the conventional lead-saving negative comb plate for welding the lead-acid storage battery, the lead-saving negative comb plate for welding the lead-acid storage battery utilizes the characteristics that if the utilization rate of a side negative plate is about 70% of the utilization rate of a middle pole plate, the current flowing on a side cathode lug is about 70% or even smaller of the current on the pole lug of the middle pole plate, the width of the pole lug of the side cathode plate is designed to be 80-90% of the width of the pole lug of the middle pole plate, the length of the tooth seams of the welding negative comb plate of the corresponding side cathode plate is correspondingly 80-90% of the length of a middle tooth seam, and correspondingly the width of a busbar trench is reduced, therefore, both the purposes of welding and current intensity bearing capability are met, and the lead consumption in welding the busbars is reduced, and the cost is lowered.
Description
Technical field
The utility model relates to the plumbous negative pecten of a kind of lead acid accumulator welding joint.
Background technology
When the pecten of existing lead acid accumulator welding use designs, each slot length of pecten is the same, and the utilance of actual top negative plate is 70% left and right of middle plate utilance, the electric current circulating on the negative electrode lug of limit is about the 70% even less of electric current on middle plate lug.The negative pecten slot length of existing welding is the same, and when welding, battery bus-bar lead loss is bigger than normal.
Utility model content
The utility model technical issues that need to address are that while providing a kind of slot length to differ, can save welding, the lead acid accumulator of the plumbous amount of consumption welds with the plumbous negative pecten of joint.
The technical solution of the utility model is: the plumbous negative pecten of joint for a kind of lead acid accumulator welding, comprise the main layered comb plate body that bar shaped is tabular, main layered comb plate body length direction one side is provided with bus-bar, has broach on bus-bar, between each broach, leave slot, the slot length between described broach is not etc.
As preferably, slot and both sides slot in the middle of described slot comprises, middle slot length is " X ", both sides slot length is " Y ", Y=(80%-90%) X.
As preferably, described bus-bar has dug busbar channel downwards perpendicular to main layered comb plate body, and the width of busbar channel is not less than the length of slot.
As preferably, described busbar channel is waveform, and minimum widith place joins with the slot keeping to the side most.
As preferably, described main layered comb plate body length direction two ends respectively have the through hole that a diameter is 12mm.
As preferably, described slot length is within the scope of 4mm-15mm.
Compared with using the plumbous negative pecten of joint with lead acid accumulator welding in the past, the utility model is 70% left and right of middle plate utilance according to the negative plate utilance in limit, the electric current circulating on the negative electrode lug of limit is about 70% even less feature of electric current on middle plate lug, by limit negative plate lug width design, it is 80%～90% of middle plate lug width, the negative pecten slot length of welding of corresponding sides negative plate should be 80%～90% of center tooth seam length mutually, corresponding busbar channel width design also reduces, like this, welding can be met and current strength can be born, reduced again the lead loss that welding bus-bar is used, reduced cost.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic top plan view of the plumbous negative pecten of joint for the welding of the utility model lead acid accumulator;
Accompanying drawing 2 is the local schematic top plan view of broach of the plumbous negative pecten of joint for the welding of the utility model lead acid accumulator.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As Fig. 1, shown in Fig. 2, the plumbous negative pecten of joint for the lead acid accumulator welding of the present embodiment, comprise the main layered comb plate body 1 that bar shaped is tabular, main layered comb plate body 1 length direction one side is provided with bus-bar 11, on bus-bar 11, have broach 12, 12 of each broach leave slot 13, slot 13 length that described broach is 12 are not etc., slot 130 and both sides slot 131 in the middle of slot 13 comprises, middle slot 130 length are " X ", slot 131 length in both sides are " Y ", Y=(80%-90%) X, when welding bus-bar 13, because the lower plumbous amount of consumption that reduces of both sides slot 131 length, and can meet welding and can bear current strength, bus-bar 11 has dug busbar channel 14 downwards perpendicular to main layered comb plate body 1, the width of busbar channel 14 is not less than the length of slot 13, busbar channel 14 is waveform, minimum widith place joins with the slot 13 keeping to the side most, main layered comb plate body 1 length direction two ends respectively have the through hole 10 that a diameter is 12mm, and slot 12 length are within the scope of 4mm-15mm.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure those skilled in the art that allow to change can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
