Abstract

PURPOSE:To ease internal stress of covering area due to expansion of main bone or residual strain of covering itself and prevent crack of covering by executing injection molding or compression molding of covering consisting of acid resistance synthetic resin to the upper main bone of clad type anode plate, leaving the stress easing hole. CONSTITUTION:A covering 5 is formed in such a way that an acid resistance synthetic resin is formed by the injection molding after the upper main bone 4 is disposed in the metallic die a for injection molding and the entire part of circumference of upper bone 4 is substantially covered. At this time, a pin b is protruded to the metallic mold a for injection molding and a stresses easing hole 6 appearing after the this pin b is removed is formed to the covering 5. Thereby, if expansion of upper main bone is generated, the stress easing hole absorbes such stress and battery performance can be stablized by providing the stress easing hole to the location which does not give any influence on other areas even when crack is generated. In this case, good shape of stress easing hole 6 which is convenient for injection molding of covering can be obtained by vertically providing said hole to the flat surface of anode plate.

機能を果さなくなるという問題があった。In order to prevent corrosion of the upper rib of the clad anode plate in this type of storage battery, it has been considered that injection molding or compression molding of a coating made of synthetic resin is applied to substantially the entire outer periphery of the anode plate. When the upper rib is completely covered with the covering part,
There is a problem in that internal stress is generated in the covering part due to expansion of the upper rib or residual stress in the covering itself, causing the covering part to crack and cease to perform its function.

That is, Fig. 1 is a front view of the main part of the clad type anode plate, Fig. 2 is an enlarged side sectional view of the main part, and Fig. 6 is the injection mold used for manufacturing the clad type anode plate of this example. It is an enlarged side sectional view of one side. In the drawings, 1 is an upper rib part, 2 is an electrode lug, and 6 is a tube.

レス緩和穴６が被覆部５に形成される。The upper rib portion 1 is composed of an upper rib 4 and a covering portion 5 made of an acid-resistant synthetic resin and covering the upper rib 4. The covering portion 5 is made by placing the upper rib 4 in an injection molding mold a and then injection molding 9 synthetic resin.
The entire circumference of the injection mold a is covered, but at this time, the injection mold a
A bottle b protrudes from the top, and a stress relief hole 6 is formed in the covering portion 5 where the bottle is removed.

なる。Battery performance can be stabilized by installing the battery in a location where even if a crack occurs, it will not affect others much. By providing the stress relief holes perpendicular to the plane of the clad anode plate, the shape of the covering portion becomes convenient for injection molding.

叙上１本発明はその工業的価値の大きいものである。Summary 1 The present invention has great industrial value.
