摘要： A breaker (1) is provided with: a fixed piece (2) which has a fixed contact; a movable piece which has a movable contact at a front end portion and pushes the movable contact against the fixed contact to bring same into contact with each other; a thermally responsive element that deforms in accordance with a change in temperature and thereby actuates the movable piece so that the movable contact separates from the fixed contact; and a case body (71) of a resin case that accommodates the fixed piece (2), the movable piece, and the thermally responsive element. The case body (71) has recess portions (75, 77) which are recessed from a peripheral portion, and the fixed piece (2) has a withdrawal portion (25) that withdraws from the recess portions (75, 77) of the case body (71) by a predetermined first distance (D1) or more, and is embedded in the case body (71).

摘要： A breaker is provided with: a movable piece (4) that has an elastically deformable elastic portion (43) and a movable contact on the tip of the elastic portion (43) and that presses the movable contact into contact with a fixed contact; a thermal actuator element (5) that is formed into a shape with a convex surface and is deformed by a change in temperature, thereby actuating the movable piece (4) so that the movable contact separates from the fixed contact; and a resin case (7) which houses the movable piece (4) and the thermal actuator element (5). The bottom surface of the base end (42a) of the movable piece (4) is positioned lower than the top (5a) of the upper surface of the thermal actuator element (5) by a distance (D). Thereby, a stable temperature adjustability and a resistance value are ensured in a breaker used as a protection device for a secondary battery with miniturization brought into realty.

摘要： A circuit breaker 1 comprises: a fixed-contact piece 2 with a fixed contact 21; a movable-contact piece 4 with a movable contact 41; a thermal actuator element 5 thermally transformable to move the movable-contact piece; a PTC thermistor 6 for conducting electricity between the movable-contact piece 4 and the fixed-contact piece 2; a main body 71 of a package provided with a holding recess 73 housing the above-mentioned components; and a cover 81 hermetically covering the holding recess 73. The fixed-contact piece 2 is embedded between an internal wall 74 and an external wall 75 of the main body 71. The PTC thermistor 6 is housed in an opened hollow 73d. In a planar view of the circuit breaker, a through-hole 76 penetrating through the external wall 75 overlaps with the opened hollow 73d, but does not overlap with the centroid O of the opened hollow 73d.
