Description

La présente invention concerne un rotor de distribution d'allumage notamment pour véhicule automobile.The present invention relates to an ignition distribution rotor, in particular for a motor vehicle.

De tels rotors de distribution d'allumage sont de plus en plus équipés d'une résistance dite d'antiparasitage disposée entre une électrode et une pièce de contact pour former un éclateur. Ce type d'éclateur est généralement obtenu par sertissage de l'électrode et de la pièce de contact aux extrémités de la résistance ce qui nécessite un stockage important des différents éléments constitutifs séparement avent assemblage.Such ignition distribution rotors are increasingly equipped with a so-called anti-interference resistance placed between an electrode and a contact part to form a spark gap. This type of spark gap is generally obtained by crimping the electrode and the contact piece at the ends of the resistor, which requires significant storage of the various constituent elements separately before assembly.

La présente invention a pour but de remédier à cet inconvénient et concerne à cet effet un rotor de distribution d'allumage pour moteur à combustion interne, comportant un éclateur du type comprenant une résistance insérée entre une électrode et une pièce de contact caractérisé en ce que la résistance est constituée d'un support isolant obtenu par surmoulage de matière isolante sur des pattes d'ancrage réalisées respectivement sur l'électrode et la pièce de contact et autour duquel est bobiné un fil résistant dont les extrémites sont fixées par soudre sur des pattes réalisées respectivement sur l'électrode et la pièce de contact.The object of the present invention is to remedy this drawback and to this end relates to an ignition distribution rotor for an internal combustion engine, comprising a spark gap of the type comprising a resistor inserted between an electrode and a contact piece, characterized in that the resistance consists of an insulating support obtained by overmolding of insulating material on anchoring lugs produced respectively on the electrode and the contact piece and around which is wound a resistant wire whose ends are fixed by soldering on lugs made respectively on the electrode and the contact part.

La description qui va suivre en regard des schémas annexés fera mieux comprendre comment l'invention peut êtré réalisée.

  • Les figures 1 à 4 représentent un procédé d'obtention d'un éclateur équipant un rotor conforme à l'invention.
  • La figure 5 représente un éclateur de rotor conforme à l'invention.
  • La figure 6 représente en coupe un rotor conforme à l'invention équipé dudit éclateur.
The description which follows with reference to the appended diagrams will make it easier to understand how the invention can be implemented.
  • Figures 1 to 4 show a method of obtaining a spark gap fitted to a rotor according to the invention.
  • FIG. 5 represents a rotor spark gap according to the invention.
  • Figure 6 shows in section a rotor according to the invention equipped with said spark gap.

De façon connue un rotor 9 distribution comporte dans un logement un éclateur 1 constitué par un résistance 4 disposée entre une pièce de contact 2 et un électrode 3; voir p.ex. DE-A-1123866.In a known manner a distribution rotor 9 comprises in a housing a spark gap 1 constituted by a resistor 4 disposed between a contact piece 2 and an electrode 3; see e.g. DE-A-1123866.

Conformément à l'invention l'éclateur 1 est constitué d'un support isolant 12 de forme préférentielle cylindrique obtenu par surmoulage de matière isolante sur des pattes d'ancrage 5 réalisées respectivement sur l'électrode 3 et la pièce de contact 2, et d'un fil résistant 7 bobiné autour du support isolant 12 et dont les extrémités sont fixées par soudure respectivement sur des pattes 6 réalisées respectivement sur l'électrode 3 et la pièce de contact 2.In accordance with the invention, the spark gap 1 consists of an insulating support 12 of preferential cylindrical shape obtained by overmolding of insulating material on anchoring lugs 5 produced respectively on the electrode 3 and the contact piece 2, and d a resistant wire 7 wound around the insulating support 12 and the ends of which are fixed by welding respectively on lugs 6 produced respectively on the electrode 3 and the contact piece 2.

Selon la figure 1 les pièces de contact 2 et les électrodes 3 sont obtenues par découpe dans une même bande 10 de matiériau conducteur et sont maintenues à un cadre 8 dans une position entre elles, équivalente à leur position fonctionnelle, par des pontets 11. Chaque électrode 3 comporte une patte d'ancrage 5 en vis à vis d'une patte d'ancrage 5 réalisée dans la pièce de contact 2. Et chacune des électrodes 3 et des pièces de contact 2 comporte une patte 6.According to FIG. 1, the contact parts 2 and the electrodes 3 are obtained by cutting from the same strip 10 of conductive material and are held in a frame 8 in a position between them, equivalent to their functional position, by bridges 11. Each electrode 3 has an anchoring lug 5 facing an anchoring lug 5 produced in the contact part 2. And each of the electrodes 3 and the contact parts 2 has a lug 6.

Le support isolant 12 est alors surmoulé sur les pattes d'ancrage 5 puis les pontets 11 découpés.The insulating support 12 is then molded onto the anchoring lugs 5 and then the cut-off bridges 11.

Le fil résistant 7 est ensuite enroulé autour du support isolant 12 et ses extrémités sont soudées respectivement à une patte 6 de l'électrode 3 et à une patte 6 de la pièce de contact 2.The resistant wire 7 is then wound around the insulating support 12 and its ends are welded respectively to a tab 6 of the electrode 3 and to a tab 6 of the contact piece 2.

La résistance ainsi formée par le support isolant 12 et le fil résistant 7 peut ensuite être imprégnée de vernis afin de faciliter la manipulation de l'élacteur vers son logement dans le rotor 9.The resistance thus formed by the insulating support 12 and the resistant wire 7 can then be impregnated with varnish in order to facilitate the manipulation of the elector towards its housing in the rotor 9.
