Abstract
The utility model relates to an electrode pole for secondary batteries with labyrinth sealing structure. A sealing connecting part of the electrode pole presents a double-tower shape, the small ends of which are opposite, and the surface of the double-tower shape is provided with a plurality of annular grooves. One layer of plastic lining is mold on the external surface of the double-tower shape, and a horizontal annular fin is connected to the upper edge of the one layer of plastic lining. The utility model can be heated and sealed with a battery casing into a whole at one time. Due to the labyrinth structure with multilayered grooves and the casting mode of the sealing surface of the electrode pole, the sealing performance of the utility model is improved, and the occurrence of the problem of liquid leakage is stopped.
Description
The utility model relates to a kind of storage battery annex, particularly a kind of battery post with labyrinth seal structure.
In the prior art, most lead battery metal poles with the fixing position of housing be isometrical light beam face form, it is tightly connected by adhesive and accumulator housing.Yet, because its surface smoothing, particularly having in the operational environment of judder at motorcycle etc., adhesive seal is very easily destroyed, thereby causes storage battery leakage problem.
The purpose of this utility model be intended to propose a kind of partial shape complexity that is tightly connected of pole, and outside this part, the labyrinth type battery post of the plastic lining of bag is to overcome the deficiencies in the prior art part.
The purpose of this utility model can realize like this.
Battery post with labyrinth seal structure comprises and bus-bar coupling part 1, the part that is tightly connected 2 and pole end 3.The part that wherein is tightly connected is the relative double tower shape of microcephaly, also is provided with a plurality of annular grooves 4 on it.Outside the part that is tightly connected, be cast with one deck plastic lining 5.
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Fig. 1 pole schematic diagram.
Fig. 2 labyrinth seal structure groove schematic diagram.
Fig. 3 double tower shape plastic lining schematic diagram.
Pole of the present utility model is designed to double tower shape at the position that is tightly connected, and being respectively equipped with a plurality of sections on two conical surfaces is trapezoidal annular groove 4.
On the surface that is tightly connected the position, by the method for casting, be surrounded by one deck plastic lining, its material is identical with the accumulator housing material, for example can be polypropylene etc.Plastic lining closely contacts with the electrode column sealing connecting portion, and fills up groove.Its profile can be cylindrical 5, or has the double tower shape 7 of 1.5mm thickness.Plastic lining on top edge place is connected with a horizontal annular overlap 6.
The utility model pole, by the plastic lining of its outside, position that is tightly connected and the plastics overlap of upper edge, can with the upper and lower cover of storage battery disposable seal whole.And the sealing surfaces of lead alloy, then because the maze-type structure of multi-layer groove, and the casting mode, its sealing property is improved greatly, stopped to climb the generation of liquid phenomenon.The utility model is particularly suited for using in motorcycle battery.
