20130299323 | Contact Structure - The present invention provides a means in which contact between contacts in a “double-break (or double-make) contact structure” occurs in two places in the same state as much as possible. A contact structure includes two fixed members ( | 11-14-2013 |
20150022311 | Protective Device - The present invention provides a protection device which provides a greater degree of freedom in a disposition of the bimetal switch as well as be able to more accurately control an actuation of the bimetal member of the bimetal switch. The protection device characterized in that the device comprises a bimetal switch wherein a first PTC member and a bimetal member are connected electrically in parallel with each other; and a second PTC member; and the bimetal member is disposed to be actuated by tripping of the second PTC member. | 01-22-2015 |
20150035641 | Protection Device - The present invention provides a protection device which comprises a resin base 14, a PTC component 24, a bimetal component 26, an arm 28 and an upper plate 46 which are housed in a resin housing wherein the resin base 14 includes a terminal 12 which is integrated with the resin base by insert molding. The protection device further includes a resin cover 16 which is formed by insert molding so as to cover the PTC component 24, the bimetal component 26, the arm 28 and the upper plate 46 which are superposed in this order over the terminal 12 within a space in the resin base 14. The space in the resin base 14 is substantially closed by the upper plate 46, the resin base 14 and the resin cover 16 are integrally bonded to define the resin housing, the terminal 12 and the arm 28 are is electrically connected in series in a normal state, and in an abnormal state where the bimetal component 26 is activated, the terminal 12 and the arm 28 are electrically cut off, while the terminal 12, the PTC component 24, the bimetal component 26, and the arm 28 are electrically connected in series in this order. | 02-05-2015 |
20150229118 | PROTECTIVE DEVICE - The present invention provide a protection device which comprises a PTC component and a first non-resettable contact component which is connected electrically in parallel to the PTC component, characterized in that a second non-resettable contact component is connected electrically in series to the PTC component, and when the PTC component is tripped by a current which is diverted by opening the contact of the first non-resettable contact component, the contact of the second non-resettable contact component opens due to heat which is generated by the PTC component. | 08-13-2015 |
