Description


  



   REVENDICATIONS 1. Dispositif de chauffage (1) électrique constitué d'une enveloppe tubulaire
 (2), à l'intérieur de laquelle est toge un élément chauffant (4) entouré
 d'isolant (3), ledit élément chauffant (4) étant relié à un circuit d'alimentation
 électrique par des tiges et broches (10,12) de connexion (14), ladite
 enveloppe tubulaire (2) étant munie de deux perles de bouchage
 cylindriques, agencées en ses extrémités, au moins   l'une    de ces perles, dite
 perle spécifique (16), étant en contact direct avec l'isolant (3) entourant
 l'élément chauffant (4), caractérisé en ce que la perle spécifique (16)
 comporte un évidement (18) la traversant axialement, dans lequel est inséré
 un fusible thermique (20) monté électriquement en série avec t'élément
 chauffant (4).



  2. Dispositif de chauffage (1) électrique selon la revendication 1, caractérisé
 en ce que l'élément chauffant (4) est en spirale et monté en tension dans
 t'enveloppe tubulaire (2).



  3. Dispositif de chauffage (1) électrique selon l'une des revendications
 précédentes, caractérisé en ce que t'évidement (18) comporte un
 rétrécissement (21) au niveau de l'extrémité en liaison avec l'intérieur du
 tube, contre lequel est positionné le fusible (20).



  4. Dispositif de chauffage (1) électrique selon   l'une    des revendications
 précédentes, caractérisé en ce que le fusible thermique (20) comporte un
 boîtier (23) à l'intérieur duquel est toge un ressort de compression (28)
 exerçant une pression entre, d'une part une pastille thermique (24) située à
 l'extrémité externe du boîtier et en contact avec une broche de connexion
 externe (12) et d'autre part un disque (26) coulissant central poussé en
 appui contre une tige de liaison (10) interne, et ceci contre une force de
 rappel exercée par un ressort (32) d'ouverture coaxial à la tige de liaison
 (10). 



  5. Dispositif de chauffage (1) électrique selon la revendication 4, caractérisé
 en ce que la tige de liaison (10) est entourée, au sein du fusible thermique
 (20), d'un isolateur (34).



  6. Dispositif de chauffage (1) électrique selon   l'une    des revendications 4 ou 5,
 caractérisé en ce que la pastille thermique (24) est située à l'extrémité du
 boîtier du fusible situé hors de l'enveloppe tubulaire (2).
