Description
Das Hauptpatent betrifft einen magnetisch steuerbaren Schaltkontakt, bei welchem einander gegenüberliegende Stirnflächen zweier flacher Kontaktfedern zur Kontaktgabe ausgebildet sind und mindestens eine der Federn in ihrer Ebene zu einer Bewegung geeignet ist. Unter dem Einfluß eines magnetischen Feldes erfolgt die Kontaktgabe bei einem derartigen Schaltkontakt durch die Berührung der beiden Stirnflächen der Federn. Die Erfindung betrifft ein Verfahren, derartige Schaltkontakte wirtschaftlich zu fertigen, sowie einen nach diesem Verfahren hergestellten Schaltkontakt. Insbesondere ist es Ziel der Erfindung, die Einstellung des richtigen Luftspaltes zwischen den zur Kontaktgabe geeigneten Stirnflächen zu erleichtern.The main patent relates to a magnetically controllable switching contact in which opposite one another End faces of two flat contact springs are designed for making contact and at least one of the springs is suitable for movement in its plane. Under the influence of a magnetic In the case of such a switching contact, contact is made by touching the field both end faces of the springs. The invention relates to a method of making such switching contacts economical to manufacture, as well as a switching contact manufactured according to this process. In particular, it is the goal of Invention, the setting of the correct air gap between the end faces suitable for making contact to facilitate.
Gemäß der Erfindung werden die beiden in einer Ebene liegenden Schaltkontaktfedern aus magnetisierbarem Material eines magnetisch steuerbaren Schaltkontaktes zunächst als ein im wesentlichen U-förmiges Stanzteil gefertigt, dessen freie Schenkel die zur Kontaktgabe geeigneten Stirnflächen tragen, und es wird sodann nach Festlegen der Lage beider Schenkel zueinander deren Verbindungssteg entfernt.According to the invention, the two switching contact springs lying in one plane are made of magnetizable Material of a magnetically controllable switching contact initially as a substantially U-shaped Stamped part manufactured, the free legs of which carry the end faces suitable for making contact, and it then, after determining the position of both legs to one another, their connecting web is removed.
Durch die Herstellung beider Schaltkontaktfedern in Form eines einzigen Stanzteils wird eine besonders rationelle Fertigung erzielt. Die beiden Schenkel des zunächst einheitlichen Stanzteils lassen sich in einfacher Weise festlegen, so daß sie nach der anschließenden Entfernung des sie verbindenden Steges ihre Lage zu einander ein für allemal beibehalten. Zweckmäßig wird der Querschnitt der beiden Schenkel des zunächst einstückigen Stanzteils unterschiedlich groß bemessen, so daß durch den einen Schenkel nur ein geringer magnetischer Nebenschluß zu dem an den zur Kontaktgabe miteinander geeigneten Flächen beider Federn auftretenden magnetischen Feld gebildet wird.The manufacture of both switch contact springs in the form of a single stamped part makes one special rational production achieved. The two legs of the initially uniform stamped part can be easily Set way so that after the subsequent removal of the web connecting them maintain their position in relation to one another once and for all. The cross-section of the two legs is expedient of the initially one-piece stamped part dimensioned different sizes, so that by one leg only a slight magnetic shunt to that of the ones suitable for making contact with one another Areas of both springs occurring magnetic field is formed.
Weiterer Erfindung gemäß wird die Größe des Luftspaltes zwischen den Schaltkontaktfedern in deren Ruhelage durch Verformung des die Federn verbindenden Steges festgelegt. Im Gegensatz zu anderen Ausführungsformen eines Schaltkontaktes, bei dem die Kontaktfedern einzeln hergestellt und mit Hilfe eines weiteren Bauteils, beispielsweise einer Glasröhre, auf den entsprechenden Kontaktabstand gebracht werden, erfolgt die Einstellung des Kontaktabstandes gemäß der Erfindung durch einfaches Eindrücken einer Sicke in den die Schaltkontaktfedern verbindenden Steg, wodurch Arbeitszeit und Fertigungskosten gespart werden.According to another invention, the size of the air gap between the switch contact springs in whose rest position is determined by deformation of the web connecting the springs. In contrast to others Embodiments of a switching contact in which the contact springs are made individually and with With the help of another component, for example a glass tube, to the corresponding contact distance are brought, the adjustment of the contact distance according to the invention is done by simply pressing a bead in the web connecting the switch contact springs, reducing working time and manufacturing costs be saved.

Fig. 1 einen Schaltkontakt gemäß der Erfindung als Stanzteil in der Draufsicht und Seitenansicht,1 shows a switching contact according to the invention as a stamped part in plan view and side view,
Fig. 2 den gleichen Schaltkontakt in den gleichen Ansichten mit durch Verformung des Steges eingestelltem Kontaktabstand,Fig. 2 shows the same switching contact in the same views with adjusted by deformation of the web Contact spacing,
Fig. 3 den Schaltkontakt im fertigen Zustand, ebenfalls in der Draufsicht und Seitenansicht.3 shows the switching contact in the finished state, also in plan view and side view.
Der in Fig. 1 dargestellte Schaltkontakt besteht aus den Schaltkontaktfedern 1 und 2, die durch einen U-förmig ausgebildeten Steg 3 miteinander verbunden sind. Der Querschnitt des Steges 3 wird im Verhältnis zu den Schaltkontaktfedern 1 und 2 so gering gewählt, daß sich außer dem über die Schaltkontaktfedern verlaufenden magnetischen Hauptfluß nur ein geringer magnetischer Nebenfluß über den Steg 3 ausbilden kann. In der in Fig. 1 dargestellten Form wird der Schaltkontakt als Stanzteil hergestellt.The switching contact shown in Fig. 1 consists of the switching contact springs 1 and 2, which are connected to one another by a U-shaped web 3. The cross-section of the web 3 is chosen so small in relation to the switch contact springs 1 and 2 that, apart from the main magnetic flux running over the switch contact springs, only a small secondary magnetic flux can develop over the web 3. In the form shown in Fig. 1, the switching contact is produced as a stamped part.
Um den Kontaktabstand 4 in der Ruhelage zwischen der Feder 1 und der Feder 2 einzustellen, wird in der in Fig. 2 gezeigten Weise in den Steg 3 eine Sicke 5 eingedrückt. Je nach der Tiefe der Sicke 5 kann die Kontaktfeder 1 der Kontaktfeder 2 in gewünschter Weise genähert werden.To adjust the contact distance 4 in the rest position between the spring 1 and the spring 2, is In the manner shown in FIG. 2, a bead 5 is pressed into the web 3. Depending on the depth of the bead 5 can the contact spring 1 of the contact spring 2 in desired Way to be approached.
Nach der Festlegung des Luftspaltes werden die Schaltkontaktfedern miteinander dadurch verbunden, daß die Schenkel 6 und 7 des U-förmig ausgebildeten Steges in Isoliermaterial 9 eingespritzt werden. Der zwischen den Schenkeln 6 und 7 des U-förmig ausgebildeten Steges liegende Teil 8 wird anschließend abgetrennt, wie in Fig. 3 dargestellt.After the air gap has been determined, the switch contact springs are connected to one another by that the legs 6 and 7 of the U-shaped web are injected into insulating material 9. Of the part 8 lying between the legs 6 and 7 of the U-shaped web is then separated, as shown in FIG. 3.
