Abstract
Description
La présente invention concerne les allume-gaz électroniques du type produi
sant des étincelles haute tension devant les brûleurs et plus particulièrement ceux pour lesquels sont requises des dimensions très petites.The present invention relates to electronic gas lighters of the product type.
high voltage sparks in front of the burners and more particularly those for which very small dimensions are required.
Les dispositifs connus de ce genre comportent un transfannateur d'impulsions haute tension dans le primaire duquel se décharge périodiquement un condensateur préalablement chargé. Known devices of this kind include a high voltage pulse transformer in the primary from which a previously charged capacitor is periodically discharged.
le transformateur d'impulsions est constitué d'un noyau magnétique autour d@quel est bobiné un primaire fait d'un petit nombre de spires de fil de diamètre généralement compris entre 0,5 et 1 mm. the pulse transformer consists of a magnetic core around which is wound a primary made of a small number of turns of wire with a diameter generally between 0.5 and 1 mm.
Concentriquement et par dessus le primaire est bcbiné un ou plusieurs enroulements secondaires constitués d'un grand narre de spires de fil fin bobinées en couches avec interposition d'isolant ou en galettes justaposées. Concentrically and above the primary is bcbiné one or more secondary windings made up of a large narre of turns of fine wire wound in layers with interposition of insulator or in justaposed wafers.
Bien qu'ayant fait leur preuve ces dispositifs présentent deux inconvénients principaux: 1) la nécessité d'un noyau magnétique,
2) des dimensions géométiques relativanent impartantes (diamètre compris entre 18 et 25 mm et longueur de 20 a 60 rmn selon le nombre de secondaires).Although these devices have proven themselves, they have two main drawbacks: 1) the need for a magnetic core,
2) geometrical dimensions that are relatively accurate (diameter between 18 and 25 mm and length from 20 to 60 nm depending on the number of secondaries).
Le but de la présente invention est de remédire à ces inconvénients en permettant la réalisation d'un transformateur d'iitpulsions de dimension très réduite requis, en particulier, pour l'équipement des appareils de cuisson extra-plats. The object of the present invention is to remedy these drawbacks by allowing the realization of a very small-size pulse transformer required, in particular, for equipping extra-flat cooking appliances.
Pour ce faire l'invention fait appel a une utilisation nouvelle des circuits imprimes. To do this, the invention calls for a new use of printed circuits.
Un transformateur d'impulsions réalisé selon l'invention est constitué d'une plaque de circuit imprimé de 0,8 mm à 1,6 nm d'épaisseur dont la face cuivrée réalise une spirale de cuivre de 4 à 8 spires et d'un diamètre extérieur voisin de 15 mm constituant le primaire du transformateur. A pulse transformer produced according to the invention consists of a printed circuit board of 0.8 mm at 1.6 nm in thickness, the copper-colored face of which produces a copper spiral of 4 to 8 turns and a external diameter close to 15 mm constituting the primary of the transformer.
le ou les bobinages secondaires est ou sont constitués d'une seule galette
d'un grand nombre de spires de fil fin d'une épaisseur d'environ 2 mn, d'un diamètre intérieur de 3 ou 4 mm et d'un diamètre extérieur identique au diamètre extérieur de la spirale. Dans le cas d'utilisation d'un seul secondaire (1 ou 2 brûleurs) cette galette est plaquée sur le circuit imprimé côté non conducteur en faisant coïncider son axe avec le centre de la spirale, dans le cas d'utilisation de deux secondaires (2 - 3 ou 4 brûleurs) la seconde galette est plaquée
sur le circuit imprimé câté cuivre avec interposition d'une rondelle isolante de même épaisseur que le circuit imprimé en faisant de même coincider son axe avec
le centre de la spirale, le couplage très serré obtenu pour ce dispositif évite
l'utilisation d'un noyau magnétique.the secondary winding (s) is or consist of a single wafer
a large number of coils of fine wire with a thickness of approximately 2 min, an internal diameter of 3 or 4 mm and an external diameter identical to the external diameter of the spiral. In the case of using a single secondary (1 or 2 burners) this wafer is pressed against the printed circuit on the non-conductive side, making its axis coincide with the center of the spiral, in the case of using two secondary ( 2 - 3 or 4 burners) the second pancake is pressed
on the copper-plated printed circuit with the interposition of an insulating washer of the same thickness as the printed circuit, making its axis coincide with
the center of the spiral, the very tight coupling obtained for this device avoids
the use of a magnetic core.
les dimensions du transformateur sont celles d'un disque de 15 mn de diamètre
et d'épaisseur canprise entre 3 et 6 mn.the dimensions of the transformer are those of a 15-minute diameter disc
and thickness canprise between 3 and 6 minutes.
L'usage d'un tel transformateur ne se limite pas aux allume-gaz mais à toutes
les utilisations requêrant un tel dispositif. The use of such a transformer is not limited to gas lighters but to all
the uses requiring such a device.
