The parts carrier 5 has a fixing pin 23 which projects into a corresponding recess on the lower leg 18 of the connecting piece 6.

Der obere Schenkel 21 des Anschlußstückes 6 ist mit einer Verbindungszone 19 versehen, an der ein an einer Bimetallfeder bzw. Bimetall 8 umwickeltes Heizelement 22 bzw. Heizleiter bekannter Art elektrisch und mechanisch verbunden ist. Diese erste Verbindungszone 19 wird mit Schutzgasschweißen bzw. einer Plasmaschweißung realisiert, wobei dieses erste Schweißpunkt 24 in der Fig. 5 näher dargestellt ist. Auch die nachfolgenden Schweißpunkte 25, 26, 27 werden mit Schutzgasschweißen realisiert.
Eine zweiter Schweißpunkt 25 ist an der Verbindungsstelle zwischen dem Heizelement 22 und dem Bimetall 8 vorhanden. Durch das Schutzgasschweißen des zweiten Schweißpunktes 25 werden Bimetall 8 mit einer Legierung, die sich nur sehr schwer schweißen läßt miteinander sicher verbunden, womit Qualitätsprobleme in dieser Hinsicht beseitigt werden.
Mit der Schutzgas- bzw. Plasmaschweißung wird das Heizelement 22 an der passiven Seite des Bimetalls 8 angeschweißt. Die passive Seite des Bimetalls 8 ist zum Schweißen gut geeignet, weil nur die aktive Seite aus einer Legierung besteht, die sich relativ schwer bzw. nicht schweißen läßt.The upper leg 21 of the connecting piece 6 is provided with a connection zone 19 to which a heating element 22 or heating conductor of known type wound on a bimetal spring or bimetal 8 is electrically and mechanically connected. This first connection zone 19 is realized by inert gas welding or plasma welding, wherein this first welding point 24 is shown in greater detail in FIG. The following welding points 25, 26, 27 are realized with inert gas welding.

The contact element 7 is partially arranged in the yoke plate 28, wherein the contact element 7 and the yoke plate 28 with recesses 39, 40 are provided
The contact element 7 is provided with a voltage applied to the parts carrier first portion 41, which is acted upon by a recess 42 which engages in a support portion 43 of the parts carrier.
Below the first section 41, a second section 44, which is bulged in the region 45 and terminates in an arranged below the parts carrier 5 end portion 46 terminates, which is arranged in the same direction as the lower leg 18 of the connecting piece 6.
In area 45 and the end portion 46, a slot motor 47 is preassembled on the parts carrier 5.
The parts carrier 5 is provided with two plate-shaped areas 49, which prevent the gases of the switching chamber of the switching device in the trip range.
The contact angle 7 is pivoted by rotating about the axis X in the direction of arrow A of Fig. 2 in the parts carrier 5 behind the support portion 43.

Wie die Figuren 11 und 12 zeigen ragen die Befestigungsnasen 3 durch die Montageöffnungen 48 am Gehäuse 12 in die Aufnahmetaschen 2 am Teileträger 5. As the figures 11 and 12 show the attachment tabs 3 protrude through the Mounting holes 48 on the housing 12 in the receiving pockets 2 am Part carrier 5.

Der Stromfluß in den an dem Teileträger 5 angeordneten Teilen fließt von dem unteren Schenkel des Anschlußstückes 6 bis zu dem ersten Schweißpunkt 24, anschließend in das Heizelement 22 bis zu den zweiten Schweißpunkt 25 anschließend über das Bimetall 8 in das Jochblech 28 bis zu dem vierten Schweißpunkt 27, anschließend in die Auslösespule 38 bis zu dem dritten Schweißpunkt 26, anschließend in das Kontaktelement 7.The flow of current in the arranged on the parts carrier 5 parts flows from the lower leg of the connecting piece 6 to the first welding point 24, then in the heating element 22 to the second welding point 25th then via the bimetal 8 in the yoke plate 28 to the fourth Welding point 27, then in the trip coil 38 to the third Weld point 26, then in the contact element 7th

Mechanisch fixiert werden das Anschlußstück 6 durch den Fixierungszapfen 23 mit dem Teileträger 5, das Jochblech 28 mit dem Teileträger 5 durch die Fixierlasche 35 und das Kontaktelement 7 mit dem Teileträger 5 an seinem Stützbereich 43.
Das Heizelement 22, und die Auslösespule werden durch die Schweißpunkte gehalten 24,25 bzw. 26,27, wodurch insgesamt alle Teile stabil an dem Teileträger 5 gehalten werden.The connecting piece 6 is fixed mechanically by the fixing pin 23 with the part carrier 5, the yoke plate 28 with the part carrier 5 by the fixing strap 35 and the contact element 7 with the part carrier 5 at its support area 43.
The heating element 22, and the trip coil are held by the welding points 24,25 and 26,27, whereby a total of all parts are stably held on the parts carrier 5.

Der Teileträger 5 besteht aus Thermoplast und wird in das Gehäuse 12, das auch aus Duroplast besteht, bzw. einem Gehäuseteil 13 verklebt, wie die anderen Teileträger der anderen Phasen auch.
Das Kleben erfolgt ohne eine zusätzliche Verbindung, wie Schraubverbindung oder Verspannen und dergleichen.The parts carrier 5 is made of thermoplastic and is in the housing 12, which also consists of thermoset, or a housing part 13 glued, like the other parts carrier of the other phases also.
The gluing is done without an additional connection, such as screw or bracing and the like.

An dem Gehäuse 12 sind, wie in Fig. 13 zu sehen ist, Klebetaschen 51,52 vorhanden, die mit einer Menge von ca. 0,010 g Klebematerial gefüllt werden. In die Klebetaschen tauchen Stifte 53,54 der Auslöseeinheit ein, die dort verklebt werden.
Die ersten Stifte 53 sind jeweils an das Jochblech 28 angeformt während die zweiten Stiften 54 an das Anschlußstück 6 angeformt sind. Ferner sind dritte Stifte 55 an das Jochblech angegformt. On the housing 12, as shown in Fig. 13, there are adhesive pockets 51, 52 which are filled with an amount of about 0.010 g of adhesive material. In the adhesive pockets dive pins 53,54 of the trip unit, which are glued there.
The first pins 53 are respectively formed on the yoke plate 28 while the second pins 54 are formed on the connector 6. Further, third pins 55 are formed on the yoke plate.

Geklebt werden nur Metallfortsätze von Blechen, die hier als Stifte 53,54 gekennzeichnet sind. Die Stifte 53, 44 sind räumlich verteilt, um einen guten halt zu gewährleisten. Insgesamt sind zwölf Stifte 53, 54, 55 vorhanden. Hierdurch entfallen jegliche Verschraubungen, die bei Thermoplasten erforderlich sind. Durch die dauerhaft feste Verbindung wird in einfacher Weise erreicht daß die Bimetallposition stabil bleibt. Thermische und mechanische Spannungen werden durch die Verwendung des Thermoplast und durch das Kleben erheblich gemindert, während die Wärme- und Formstabilitat gewährleistet wird.Only metal extensions of sheet metal are glued here as pins 53,54 Marked are. The pins 53, 44 are spatially distributed to a good to ensure. There are twelve pins 53, 54, 55 in total. This eliminates any screw that is used in thermoplastics required are. Due to the permanently fixed connection becomes in a simple way ensures that the bimetallic position remains stable. Thermal and mechanical Tensions are caused by the use of the thermoplastic and by the Adhesion is significantly reduced while the heat and shape stability is guaranteed.

Die Auslöseeinheit ist, wie Fig. 15 zeigt, in dem mittleren Gehäuseteil 14 integriert.The trip unit is, as FIG. 15 shows, in the middle housing part 14 integrated.

Der vormontierte Teileträger wird in das Gehäuse 12 in hierfür vorhandene Kammern eingeschoben. The preassembled parts carrier is in the housing 12 in existing therefor Chambers inserted.
