摘要

Improvements in threaded parts for the connection of two thermoelements in ignition safety devices for gas burners, in which two thermoelements can be connected that serve for the ignition insurance of gas burners and with which an element can be fixed, in a hermetic manner, to a gas armature containing an electromagnet excitable by the current of said thermoelements, one of whose poles, the central pole through a contact disk, housed axially movable in the metal housing of this threaded part and electrically insulated in relation to this casing, it can be connected to the parts that push this disc when connecting the thermoelements against the said central pole, characterized, because the metal casing of the threaded part develops as a plug nut in whose closed bottom there are the threaded holes for the connection nozzles of the thermoelements and because, in addition, the contact disk that it is loose in the casing is secured against falling out of the casing by means of a ring placed on it which, by screwing the cap nut onto the gas armor, seals the electromagnet element against the armature.
