Abstract

Parallel contacts to the central section, together with positioning using the plunger with balls produces a small size unit with a reduced effort need to return to the neutral position.

Description

La présente invention concerne un système d'interrupteur à quatre positions qui permet d'établir trois contacts électriques.The present invention relates to a four position switch system which allows establish three electrical contacts.

Actuellement les systèmes existants sur le marché sont de tailles importantes. De plus, les contacts sont perpendiculaires à l'axe de déplacement du "noyau plongeur".Currently the existing systems on the market are of large sizes. Moreover, the contacts are perpendicular to the axis of movement of the "plunger core".

Le système d'interrupteur à quatre positions. objet de la présente invention réduit considérablement cette taille. Il permet en outre d'obtenir des contacts parallèles au noyau, d'une part, et d'autre part un système de positionnement du noyau plongeur par des billes, et ce avec un effort réduit pour le retour en position neutre .The four position switch system. object of the present invention reduced considerably this size. It also makes it possible to obtain contacts parallel to the core, on the one hand, and on the other hand a system for positioning the plunger core by balls, and this with a reduced effort to return to neutral position.

  • a set of strips (3),
  • a spring (4),
  • one or two rubber rings (5),
  • a set of marbles (6)
  • a brass ring (7).

Le corps (1) et le noyau (2) sont en matière isolante (nylon, téflon backelite, plastique, résine, etc.), les lamelles (3) en acier, cuivre et laiton, le ressort (4) en acier ordinaire ou inox, le caoutchouc (5) en PTFE non conductible, et les billes (6) en acier ou nylon.The body (1) and the core (2) are made of insulating material (nylon, Teflon backelite, plastic, resin, etc.), the blades (3) in steel, copper and brass, the spring (4) in ordinary steel or stainless steel, the rubber (5) in non-conductive PTFE, and balls (6) in steel or nylon.

Selon les plans de fabrication joints au présent dossier, les pièces de ce système comportent les caractéristiques suivantes:According to the manufacturing plans attached to this file, the parts of this system include the following features:

Le corps creux (1) comporte sur son diamètre supérieur des trous perpendiculaires à l'axe qui permettent de recevoir les contacts électriques ainsi que les billes de positionnement du noyau.

At the base of the hollow body. holes parallel to its axis are used to hold the end slats.

Le noyau plongeur (2) possède des escaliers circulaires sur lesquels les billes (6) glissent et viennent indexer la positon. Ces escaliers ont pour fonction d'opposer un effort à l'enfoncement du piston et de libérer ainsi toutes contraintes au retour en position zéro.The plunger core (2) has circular staircases on which the balls (6) slide and come to index the position. These stairs have the function of opposing an effort to depression of the piston and thus releasing all constraints upon returning to the zero position.

Le sommet du noyau comporte une bague en laiton (7) recouverte d'or, montée, serrée et collée sur le noyau, qui assure le contact électrique. A sa base un trou dans l'axe permet de loger le ressort.The top of the core has a brass ring (7) covered with gold, mounted, tightened and glued to the core, which provides electrical contact. At its base a hole in the axis allows to house the spring.

Les lamelles (3) comportent des trous et reçoivent soudé ou serti des contacts or. L'extrémité est découpée pour permettre la soudure sur un support électrique.The lamellae (3) have holes and receive soldered or crimped gold contacts. The end is cut to allow welding on an electrical support.

Le ressort (4) travaille en compression. The spring (4) works in compression.

Les bagues en caoutchouc (5) permettent un contact électrique entre les lamelles (3) et la bague en laiton (7) ainsi que le maintien en appui des billes (6) sur l'escalier du noyau (2). Le contact électrique est de type autonettoyant par le frottement du contact sur la bague en cuivre.The rubber rings (5) allow electrical contact between the slats (3) and the brass ring (7) and the bearing support of the balls (6) on the staircase of the core (2). The electrical contact is of the self-cleaning type by the friction of the contact on the ring in copper.

Les billes (6) permettent de positionner le noyau en glissant sur l'escalier, et de donner ainsi une information sensitive de la position.The balls (6) make it possible to position the core by sliding on the staircase, and thus giving sensitive position information.

La bague en laiton (7) doré assure le contact entre la lamelle (3) qui amène le courant (commun) et celle qui le redistribue. Selon d'autres variantes, une cale en matière isolante peut s'intégrer dans le fond du corps creux (1) pour permettre de diminuer le nombre de contacts.The golden brass ring (7) ensures contact between the strip (3) which brings the current (common) and the one that redistributes it. According to other variants, a shim made of insulating material can be integrated into the bottom of the hollow body (1) to reduce the number of contacts.

Selon d'autres variantes, le nombre d'escaliers peut varier sans limite et entraíner une modification du nombre de contacts.According to other variants, the number of stairs can vary without limit and lead to a modification of the number of contacts.

Le fond du corps (1) possède un centrage extérieur pour assurer la position sur un support et éventuellement être fixé à l'aide d'une vis. Le ressort (4) est guidé dans le corps (1) par l'intermédiaire d'un doigt de centrage.The bottom of the body (1) has an external centering to ensure the position on a support and possibly be fixed with a screw. The spring (4) is guided in the body (1) by through a centering finger.

La possibilité de modifier l'effort à l'enfoncement du noyau peut se faire en modifiant la résistance du caoutchouc (5) et du ressort (4).The possibility of modifying the force at the core insertion can be done by modifying the resistance of rubber (5) and spring (4).

L'effort exercé sur le noyau plongeur (2) donne une sensation tactile des positions qui peuvent être modifiées en intervenant sur la forme et la profondeur des crans de l'escalier du noyau plongeur.The force exerted on the plunger core (2) gives a tactile sensation of the positions which can be modified by intervening on the shape and the depth of the notches of the staircase of the core diver.
