Abstract
Disclosed is an embedded pole piece of copper cores for lead-acid accumulators. The pole piece is characterized in that screw threads are disposed in the middle of copper cores, tins are gilded on the surface of the copper cores, and cross hatches and a break are arranged on the lower portion of the copper cores. The screw threads in the middle of the copper core are M5-M10, the thickness of the tin gilded on the surface of the copper core is 5 to 15 mu meters, the deepness of the cross hatches arranged on the lower portion of the copper core is 0.4 to 1 millimeter, the width of the break arranged on the lower portion of the copper core is 4 to 10 millimeters, and the deepness is 2 to 5 millimeters. The surface of the copper core of the utility model is gilded with tin, and thereby contact electrical resistance is reduced resulting from the strong combination of the tin and the lead in casting time. Besides, the cross hatches and the break are disposed on the lower portion of the utility model, which reduces the electrical resistance on one hand, and increases the torque of the pole piece on the other hand. Further, the screw threads disposed in the middle is convenient for the connecting of batteries.
Description
Technical field
The utility model relates to a kind of lead acid accumulator with copper in-core embedding pole, belongs to the lead-acid battery field.
Background technology
The lead-acid battery pole has lead terminal post, copper in-core embedding pole, stainless steel bolt built-in mosaic polar column at present.The lead terminal post internal resistance is little, basic non-contact resistance, but long-term the use and pole flexible type distortion during heavy-current discharge, even melt, very dangerous; The stainless steel built-in mosaic polar column, strength ratio is better, but touches badly with lead joint, and contact resistance is big, does not also utilize heavy-current discharge; The present copper in-core embedding pole that uses, copper core itself is littler than the resistance of plumbous and steel, but owing to touch bad with lead joint, have the big shortcoming of contact resistance equally, and when connecting between battery, the moment of torsion when attachment screw is tightened when generally requiring battery to install is 15N.M, so require between copper core and the lead adhesion strong, the copper core does not reach this requirement at present, often occurs battery burning and explosion phenomenon on the market, loses very big.
Summary of the invention
The purpose of this utility model provides a kind of lead acid accumulator copper in-core embedding pole that reduces contact resistance, increases moment of torsion when connecting, is convenient to connect between battery.
The technical solution of the utility model is: lead acid accumulator comprises copper core and lead base body with copper in-core embedding pole, has screw thread, surface to have zinc-plated coating, bottom that reticulate pattern and breach are arranged in the middle of the copper core.Screw thread in the middle of the copper core is M5～M10, and electroplating surfaces with tin thickness is 5～15 μ m, and the bottom reticulate pattern degree of depth is 0.4～1mm, and the down gap width is that 4～10mm, the degree of depth are 2～5mm.
Adopt above technical scheme, the copper wicking surface is zinc-plated, and copper core and tin adhesion are strong, and when the casting pole, tin and plumbous adhesion are strong, reduce the contact resistance of copper in-core embedding pole; Reticulate pattern and breach are arranged at copper core bottom, reduce the contact resistance of copper in-core embedding pole on the one hand, can increase the torque of copper in-core embedding pole on the other hand, guarantee to be connected firmly, and can not have an accident; There is screw thread the centre, is convenient to connect between battery.

Fig. 2 is the utility model copper cored structure schematic diagram.
Embodiment
As figure, the copper wicking surface is coated with tin layer 1, and tin layer 1 is good with copper matrix 2 contacts; In the middle of the copper core screw thread 3 is arranged, be convenient to connect between battery; Reticulate pattern 4 and breach 5 are arranged at the bottom, reduce the contact resistance of copper in-core embedding pole on the one hand, can increase the torque of copper in-core embedding pole on the other hand, guarantee to be connected firmly, and can not have an accident.Copper core A and lead base body B are combined into copper in-core embedding pole, and the improvement through to the copper core makes copper core A combine closely with lead base body B, has reduced contact resistance, has increased the torque of copper in-core embedding pole, guarantees to be connected firmly.Internal combustion engine vehicle lead-acid battery copper in-core embedding pole, middle screw thread is M10, and electroplating surfaces with tin thickness is 10 μ m, and the bottom reticulate pattern degree of depth is 0.8mm, and the down gap width is that 4mm, the degree of depth are 2mm.The diesel locomotive starting current is 2100A, and the time is 7S, uses the copper in-core embedding pole after improving, and pole does not have any anomaly, connects with the 20N.M moment of torsion, and pole is not loosening.
