摘要： PROBLEM TO BE SOLVED: To weld posts within adjacent cells in a through hole with no defects by forming the tip of a welding electrode in conical trapezoid of first and second two steps, using the bottom surface of the first conical trapezoid as the top surface of the second conical trapezoid, forming the bottom angle of the second conical trapezoid in the specified range, and limiting the relation between the tip diameter of the first conical trapezoid and the through hole diameter to the specified range. SOLUTION: An electrode 8 is brought into contact with a through hole 5 through a partition wall 4 by pushing a post, and has the tip of a first conical trapezoid 7 whose diameter D is smaller than the diameter D' of the through hole 5. The post of the electrode 8 is pushed in the through hole 5 by applying the constant pressure, and since the electrode 8 follows in the expansion 1 contraction caused by temperature change in welding or by melting/solidifying of the post, an inclined part 14 serving as a wedge is formed in the electrode 8. The bottom angle 8 of a second conical trapezoid is made 5-20 deg. to ensure the sufficient pressure contact force and forging pressure action between the post and the partition wall 4. By making the tip diameter D of the electrode 8 to be 60-80% of the diameter D' of the through hole 5, blowhole is prevented, and unstable contact between adjacent posts caused by deformation producing when the post is pushed in the through hole 5 is prevented.

摘要： PROBLEM TO BE SOLVED: To establish a penetrative welding method to generate inter-cell connection of a lead-acid battery, with which it is possible to eliminate defects in the welds of the battery and provide an excellent anti-corrosiveness and mechanical strength. SOLUTION: The bulkhead cross-section of a through hole internal wall which is initially in the condition near the right angle is made V-shape. Concretely, a penetrative welding is performed using a battery jar to meet the relations that the angle θ formed by the through hole internal wall 14 to the external wall 15 of bulkhead is under 90 deg. and that the ratio P=θ/θ' is 0.75

摘要： PROBLEM TO BE SOLVED: To provide a wound type battery cell that can easily fix a group of wound electrodes to the cell container and is capable of withstanding severe vibrations and shocks over a long period of time. SOLUTION: A shaft core 1 is composed of a rigid member 6, made of polypropylene being a mixture of 30% glass fiber and a soft member 7a, made of elastically deformable natural polypropylene. The soft member 7a has a minimal outside diameter pat that is 0.4 mm smaller than the outside diameter of the rigid member 6. This soft member 7a is deformed elastically, when the lid 5 is fitted onto the opening of the cell container 3 by pressing it from the outer terminal side. After fitting, the soft member 7a repels and then the shaft core 1, a pole pillar edge portion 9, and a ceramic washer 10 are pressed down against each another, whereby fixation between the wound electrodes and the pole pillar edge portion 9 is attained.

摘要： PROBLEM TO BE SOLVED: To form a terminal with no possibility of entering electrolyte by eliminating a gap between the inner peripheral face of a bushing and the outer peripheral face of a pole when forming the terminal of a lead acid battery and to keep it in a well welded condition with no defect. SOLUTION: When a battery jar cover 3 is injection-molded, a lead alloy bushing 4 is insert-molded and embedded therein. A strap 2 is formed on the ears 1 of a plurality of pole plates constituting a pole plate group with a CCD (cast-on strap) method and a pole 5 is integrally formed on the strap 2. The pole 5 is provided with a setting 7, which is put in contact with the lower end face of the bushing when the pole 5 is inserted through the bushing 4, to block the lower end of a gap between the inner peripheral face of the bushing and the outer peripheral face of the pole. In such a state, a molten lead alloy is poured into the gap and then the bushing and the pole are melted with the heat of the molten lead alloy and welded together.

SOLUTION: Plates 3 made of insulation resin are arranged at the upper and lower sides of a battery pack 1. Perimeter of the plates 3 and shorter than that of the battery pack 3. Three pieces of cross-shaped bus bars and a T-shaped bus bar are buried in the plate 3, and a plate opening part 15 is formed to the part where a unit cell 2 and the bus bar are welded. In order to detect the voltage of respective unit cells 2, openings are formed at four places of the upper and lower plates 3. A voltage detection wire 13 is adhered and fixed to a concavity formed to the plates, and soldered to the central part of respective bus bars. Respective unit cells 2 are arranged on the basis of a positioning protrusion 16, and respective terminals of the unit cells are spot- welded to the bus bars. A heat-shrinkable tube is not damaged by the edges when covering the battery pack, and the connection is made easy by the spot- welding. COPYRIGHT: (C)2003,JPO
