Embodiment

[0023] Embodiment: press this sealing structure, manufactured the cylindrical Zn-Ni primary battery of AA size and Zn-MnO 2 Five each. according to Figure 2-7The shape and size of manufacturing parts: lower negative cover, explosion-proof plug, upper negative cover, sealing ring, steel cylinder, copper nails. Copper nail (7) is welded in the middle of lower negative pole cover (2), vertically, must not block lower negative pole cover (2) pore (21). The upper negative electrode cover (4) is placed flat on the lower negative electrode cover (2), and the explosion-proof plug (3) is placed in the middle to assemble the negative electrode current collector ( Figure 7 ). Press (81), (82) to fix the upper negative electrode cover (4) and make good contact with the lower negative electrode cover (2). Insert it into the middle hole (51) of the sealing ring (5), and the outer diameter and the inner diameter of the sealing surface of the sealing ring (5) are closely matched (55), a...

Abstract

The present invention discloses a cylinder-shaped basic battery closure arrangement using Zn grease as negative electrode, wherein the copper nails inserted into the negative pole Zn grease is welded to the lower negative pole cover, the top negative pole cover is connected to the lower negative pole cover, an explosion-proof ball is arranged therein to form a negative pole current colleting member, which are packaged in the packing ring together, thus forming a sealing member, the sealing member is loaded into the steel cylinder, and a groove rolling and edge rolling process is utilized to compress both the radial and the axial directions of the sealing ring, thus achieving the purpose of battery sealing.

Description

Technical field [0001] The invention relates to the improvement of sealing structure in cylindrical primary and secondary chemical power sources. Background technique [0002] Due to the good wettability of the KOH solution and the steel cylinder, and the high internal gas pressure, the cylindrical alkaline battery is easy to climb alkali and leak. The round alkaline zinc-manganese primary batteries currently produced are sealed in the following way: use zinc paste as the negative electrode, and insert a copper nail into the zinc paste as the current collector. The copper nail is first welded to the negative electrode cover, and then inserted into the middle hole of the sealing ring to assemble the sealing body. Then put it into the steel cylinder that has been equipped with positive and negative electrodes. The outer diameter of the sealing ring matches the inner diameter of the mouth of the steel cylinder. The outer diameter of the negative electrode cover or another me...
