Chaque extrémité de la résistance électrique 3 est introduite et fixée, par exemple par brasure, dans les logements cylindriques correspondants 11, 12 de l'embase 2 conductrice de la chaleur pour traverser cette dernière de manière étanche afin que les bornes de connexions 14 soient placées au-dessus du fond 15 de ladite embase et à l'opposé des moyens de fixation 6.Each end of the electrical resistance 3 is introduced and fixed, for example by brazing, into the corresponding cylindrical housings 11, 12 of the heat conducting base 2 to pass therethrough in a sealed manner so that the connection terminals 14 are placed above the bottom 15 of said base and opposite the fixing means 6.

Les bornes de connexion 14 de la résistance électrique 3 sont solidaires chacune d'un écrou 21 coopérant avec des vis 22 pour permettre la retenue du boîtier isolant 5 sur l'embase 2 conductrice de la chaleur.The connection terminals 14 of the electrical resistance 3 are each integral with a nut 21 cooperating with screws 22 to allow the retention of the insulating housing 5 on the base 2 of the heat conducting.

La sonde de régulation 4 est constituée, à la manière connue, d'un tube borgne dans lequel est montée une tige axiale ou tige invar 16 à faible coefficient de dilatation.The control probe 4 consists, in the known manner, of a blind tube in which is mounted an axial rod or invar rod 16 with a low coefficient of expansion.

La sonde de régulation 4 est introduite et fixée, par exemple par brasure, dans le logement cylindrique 13 de l'embase 2 conductrice de la chaleur pour traverser cette dernière de manière étanche afin que l'une des extrémités de la tige axiale ou tige invar 16 soit placée au-dessus du fond 15 de ladite embase et à l'opposé des moyens de fixation 6.The regulation probe 4 is introduced and fixed, for example by brazing, in the cylindrical housing 13 of the heat conducting base 2 to pass therethrough in a sealed manner so that one of the ends of the axial rod or invar rod 16 is placed above the bottom 15 of said base and opposite the fixing means 6.

L'extrémité de la tige invar 16 débouchant au-dessus du fond 15 de l'embase 2 conductrice de la chaleur coopère par l'intermédiaire d'un écrou 19 avec un levier isolant 20 permettant d'actionner un rupteur électrique assurant le pilotage de la résistance électrique 3 et donc de la régulation de la température de l'eau à l'intérieur du ballon d'eau chaude 8.The end of the invar rod 16 opening above the bottom 15 of the base 2 conducts heat cooperates via a nut 19 with a lever insulator 20 for actuating an electrical switch controlling the electrical resistance 3 and therefore the regulation of the water temperature inside the hot water tank 8.

Le levier isolant 20 est actionné par les mouvements de la tige d'invar 16 disposée à l'intérieur du tube de la sonde de régulation 4 qui se dilate sous l'effet de la température ou de la chaleur.The insulating lever 20 is actuated by the movements of the invar rod 16 disposed inside the tube of the regulating probe 4 which expands under the effect of temperature or heat.

De l'autre coté, la lamelle de connexion 28 est fixée au boîtier isolant 5 par un unique rivet 32 de manière que son premier contact 33 soit en regard du contact 26b de la lame rigide 25b de la seconde pièce conductrice 23b, tandis que son second contact 34 est en regard d'un contact 35 solidaire d'une lamelle élastique et conductrice 36 montée mobile et articulée par rapport à une pièce de connexion 38 fixée dans le boîtier isolant 5.On the other side, the connection strip 28 is attached to the insulative housing 5 by a single rivet 32 so that its first contact 33 is opposite the contact 26 b of the rigid blade 25 b of the second conductive member 23 b, while its second contact 34 is opposite a contact 35 secured to a resilient and conductive strip 36 mounted movably and articulated with respect to a connection piece 38 fixed in the insulating housing 5.

La lamelle élastique 36 coopère librement avec la pièce de connexion 38 qui est fixée au boîtier isolant 5 par l'intermédiaire de rivets 39 et 40 dont l'un et plus particulièrement le rivet 40 est traversé par une vis 22 permettant la fixation dudit boîtier isolant 5 sur l'embase 2 conductrice de la chaleur.The resilient lamella 36 cooperates freely with the connecting piece 38 which is fixed to the insulating casing 5 by means of rivets 39 and 40, one of which, and more particularly the rivet 40, is traversed by a screw 22 enabling the fixing of said insulating casing. 5 on the base 2 conducts heat.

La pièce de connexion 38 est destinée à assurer la liaison électrique avec l'autre borne de connexion 14 de la résistance électrique 3.The connecting piece 38 is intended to provide the electrical connection with the other connection terminal 14 of the electrical resistance 3.

Les lamelles de connexion 27, 28 sont actionnées par un coulisseau isolant 37 qui vient prendre appui sur le disque bimétallique 18 du coupe-circuit thermique de sécurité ou sur tout autre système de sécurité comme, par exemple, à ressort à mémoire de forme .The connecting strips 27, 28 are actuated by an insulating slider 37 which bears on the bimetallic disc 18 of the safety thermal cut-out or on any other safety system such as, for example, with a shape memory spring.
