摘要： PROBLEM TO BE SOLVED: To provide a thermal protector having high reliability and high versatility of use as a protection device.
SOLUTION: A first to fourth terminals 4b, 5b, 6b, 7b are drawn out from a housing 3 made of synthetic resin, and a trimetal piece 8 is displaceably arranged (rockable) inside the housing 3, and the fixed end of the trimetal piece 8 is conducted to the first terminal 4b. Furthermore, by conducting the tip part of a narrow part 10 formed on the fixed end side of the trimetal piece 8 to the second terminal 5b, a current fuse is formed between the first terminal 4b and the second terminal 5b. Then, because a movable contact point member 9 installed on the free end side of the trimetal piece 8 is made to be positioned between the first fixed contact point 6a installed at the third terminal 6b and the second fixed contact point 7a installed at the fourth terminal 7b, and the trimetal piece 8 is inversed at a prescribed temperature, this device is constituted so that the conduction state between the movable contact point member 9 and first and second fixed contact points 6a, 7a is switched.

摘要： PROBLEM TO BE SOLVED: To solve the problem in a conventional pressure sensitive current breaker structure for a battery using a pair of U-shaped terminals that the area occupied by the terminals is too large to accommodate the thinner profile of the battery, in particular, for batteries requiring a thinner profile. SOLUTION: A pressure sensitive current breaker structure for a battery has at least two holding plates 5, 6, formed of conductive metal plates, adhered to the outer surface of an external member 2. One holding plate 5 is connected to one of electrodes 3 and a brittle element 8 forming a current path 10 is connected between two holding plates 5, 6. As the element 8 is broken by the expansion of the external member 2, the current path 10 is shut off to cause interruption of continuity between two holding plates 5, 6. Therefore, the need for a conventional U-shaped terminal is eliminated and the pressure sensitive current breaker structure for the extremely thin battery is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a sealed member with means for preventing the connecting part from being subjected to concentrated stress leading to process hardening and cracking, which are caused by sharp change of the connection thickness. SOLUTION: In the present sealed member attached with a safety valve, the connecting part 4g of the safety valve part Z is formed, as thin case, with the lid 4 and the projection part 4f, and the connecting part 4g is provided with curved surface in the inner and outer part thereof in order to give the thinner central part of the connecting part 4g and further to become thicker toward the lid 4 and the projection part 4f from the central part. Therefore, the present invention provides the sealed member attached with a safety valve, being characterized in that the connecting part 4g may be subject not to concentrated stress and to lower process hardening, thus obtaining the connection part 4g with less cracking due to not causing the sharp change of thickness of the connecting part 4g between the lid 4 and the projection part 4f.

摘要： PROBLEM TO BE SOLVED: To prevent deformation even if an impact such is impressed to an insulating material when dropped by mounting an exposed metal plate on the surface on the battery lid side of the insulating material and by connecting the metal plate with the battery lid through a welding hole drilled in the insulating material at the portion. SOLUTION: A metal plate 17 is mounted on a welding bole 12j on the outer side than a position where an inner terminal 16 is buried, on an insulating member 12. An connecting portion of the metal plate 17 is welded with a bottom plate 11b of a battery lid through the welding hole 12j. Thus, the left, end portion of the insulating member 12 is fixed to the battery lid 11, the insulating member 12 is fixed and mounted to the battery lid 11 at two points with a rivet 14 and the metal plate 17. Therefore, even when pressure in the battery rises to strongly flow high pressure gas into a recessed part in a diaphragm portion D, this reaction is prevented from deforming the insulating member 12 on the diaphragm portion D side downward. As a result, damage such as short in which an inner terminal 16 abuts to an electric generating element due to this deformation can be prevented.
