Definitions
- the invention relates to a circuit breaker according to the preamble of claim 1.
- a circuit breaker has the task of shortening the current interruption in the event of a trip caused by a short circuit or line overload and in the event of a short circuit limiting the current to a minimum that the line to be protected cannot be damaged in the event of an error.
- Such miniature circuit breakers are now produced in large quantities, partly fully automatically, so that the number of individual parts required for the function of the miniature circuit breaker, but also their ease of installation, are decisive for the economic success of this series product.
- the adjustment effort for the calibration of the overcurrent release, but also the connections of the individual components through which the current flows, designed as a welding or soldering point delay the production process.
- the object of the invention is therefore to provide a strongly current-limiting circuit breaker of the type mentioned in the introduction, in which any stranded connection can be dispensed with, which manages with only two welded or soldered connections and which does not require any adjustment effort.
- the illustration shows schematically a circuit breaker with arc extinguishing device, switching mechanism and overcurrent release.
- the arc chamber 1 there are, parallel to the chamber bottom wall, quenching plates 2, a contact arrangement 3, 4 and arc guide rails 5, 6.
- the arc guide rail 6, on which the stationary contact piece 3 is attached, stands on the one hand with the coil of the overcurrent release 7 via the welding point 8 in connection, which in turn is connected at its other end via the welding point 9 to a connecting terminal 10.
- the arc guide rail 5 flanks the lower quenching plate of the stack and forms a bearing 11 for the movable contact 4 with a rear extension 5a.
- the arc guide rail 5 is arranged vertically in front of the quenching plates with an extension 5b which carries the connecting terminal 12.
- the contact spring 13 is supported at one end in the housing 14 and presses the movable contact 4 against the fixed contact 3 in the switched-on state.
- FIG. 1 shows this state and the force acting on the bearing point in the direction of the arrow and caused by the current flow.
- the switching mechanism 15 is only shown for better understanding, it is of no importance for the short-circuit shutdown.
- the current runs with closed contacts along the arrows shown from the terminal 12 via the arc guide rail 5 and the bearing 11, the movable contact 4 to the fixed contact 3 and from there via the coil of the overcurrent release 7 to the terminal 10.
- the movable contact 4 flung away from the fixed contact 3 and the current interrupted.
- the movable contact 4 goes into the position shown in FIG. 2, the arc drawn between the movable contact and the fixed contact jumping over from the movable contact to the arc guide rail 5 after reaching the open position. Due to the blowing effect of the power supply lines, the arc is driven into the quenching plate stack and extinguished there.

Claims (7)
- Disjoncteur de protection de ligne à interruption simple, se composant
d'un déclencheur à maximum de courant (7);
d'un mécanisme interrupteur (15) qui peut être actionné par le déclencheur à maximum de courant (7) et manuellement;
d'un dispositif d'extinction d'arc comportant un empilage de tôles d'extinction (2) qui est délimité par des rails de guidage d'arc (5, 6); et
d'un système de contacts qui est prévu du côté frontal devant l'empilement de tôles d'extinction (2) dans une chambre d'extinction d'arc électrique et qui comprend un contact fixe (3) et un contact mobile (4), le contact fixe (3) étant relié galvaniquement à une borne de connexion (10) par l'intermédiaire du déclencheur à maximum de courant (7), le contact mobile (4) étant relié galvaniquement à une borne de connexion (12) par l'intermédiaire d'un rail de guidage d'arc (5, 5a; 5, 5b), et un point d'appui (11) pour le contact mobile (4) étant forme sur le rail de guidage d'arc (5a),
caractérisé
en ce que le contact mobile (4) comporte, à son extrémité libre, une partie conductrice qui est coudée jusqu'au point de contact des contacts et qui s'étend à peu près parallèlement à une partie conductrice qui relie le déclencheur à maximum de courant (7) au contact fixe (3), et
en ce que, pour accroître la pression au point d'appui (11) du contact mobile (4) et pour qu'un couple de rotation soit exercé sur le contact mobile (4), dans le sens de l'ouverture, par les forces électromagnétiques exercées sur les parties conductrices parallèles, la partie conductrice coudée du contact mobile (4) forme une tangente à un cercle dont le centre se trouve dans la région du point d'appui (11). - Disjoncteur de protection de ligne selon la revendication 1, caractérisé en ce que la partie conductrice qui relie le déclencheur à maximum de courant (7) au contact fixe (3) forme, dans la région de l'arrivée de courant au point de contact, un angle obtus avec la surface de contact des contacts, ce qui donne lieu, avec l'extrémité libre du contact mobile (4), à un tracé en U pour la conduction du courant, l'axe du U étant à peu près parallèle à la surface de fixation du disjoncteur de protection de ligne ou aux tôles d'extinction de celui-ci.
- Disjoncteur de protection de ligne selon la revendication 1 ou 2, caractérisé en ce que, pour la production d'un couple de rotation agissant sur le contact mobile (4) dans le sens de l'ouverture des contacts au moyen de forces électromagnétiques répulsives, le rail de guidage d'arc (5) réalisé sous forme de point d'appui (11) pour le contact mobile (4) présente un segment qui s'étend à proximité immédiate du contact mobile et parallèlement à celui-ci.
- Disjoncteur de protection de ligne selon la revendication 3, caractérisé en ce que les segments parallèles du rail de guidage d'arc (5) et du contact mobile (4) sont disposés à peu près perpendiculairement aux tôles d'extinction et au plan de fixation du disjoncteur de protection de ligne et s'étendent en direction du point d'appui (11).
- Disjoncteur de protection de ligne selon l'une quelconque des revendications 1 à 4, caractérisé en ce qu'afin d'éviter que la racine de l'arc touche le point d'appui (11), le contact mobile (4) est monté pivotant au point d'appui (11), du côté du rail de guidage d'arc (5) orienté à l'opposé de l'empilement de tôles d'extinction (2).
- Disjoncteur de protection de ligne selon l'une quelconque des revendications 1 à 5, caractérisé en ce que le contact mobile (4) est pressé contre le contact fixe (3), dans la position de fermeture, par un ressort de contact (13) prenant appui dans le boîtier (14), ressort dont la direction d'action passe à proximité du point d'appui (11) et qui a en plus pour effet de repousser le contact mobile (4) dans le point d'appui (11), le contact mobile (4) n'ayant pas de liaison mécanique avec le mécanisme interrupteur (15).
- Disjoncteur de protection de ligne selon l'une quelconque des revendications 1 à 6, caractérisé en ce que les contacts (3, 4) du système de contacts sont reliés galvaniquement, sans câble torsadé , à leurs bornes de connexion respectives (10, 12).
