- the axial insertion depth of the carrier 2 is thereby injection-molded anchor point 3 of the terminal connection 4 determined on the housing of the heating chamber 1.
- the protective device has two opposite ones per phase Grooves 5, which are a defined undersize with respect to Width (anchor point 6 to opposite anchor point 6) and the material thickness 7 of the carrier 2, thus to get a better tight fit.
- the carrier 4 provide clamp connections of the chamfered clamping tabs 8 of the clamping leg 9 in pockets of the housing 10 for additional stability.
- These clamping legs 9 are parallel to the carrier wrapped with bimetallic strip 11, second carrier 5 without clamping legs are used if none Load on the beam 2 in the form of parasitic torsional moments on the part of the terminal connection 4 and / or the bimetallic release (Fig. 4 or 5) occur.

Abstract
Description
Die Erfindung betrifft eine Überlastmelde- und/oder Überlastschutzeinrichtung mit einem in einem Gehäuse befestigten elektrisch leitfähigen Träger für einen Bimetallauslöser.The invention relates to an overload detection and / or overload protection device with one attached in a housing electrically conductive carrier for a bimetallic release.
Bekannt sind derartige Überlastmelde- und/oder Überlastschutzeinrichtungen durch auf dem Markt befindliche Geräte, bei denen der Träger des Bimetallauslösers durch Schraub-, Niet- oder Klebeverbindungen am Gehäuse befestigt ist. Nachteilig bei allen Befestigungsarten ist, daß durch Setzeffekte des Kunststoffgehäuses ein Teil der ursprünglich vorhandenen Vorspannkraft dieser Befestigungsarten verlorengeht.Such overload detection and / or overload protection devices are known through devices on the market which the carrier of the bimetal release by screw, rivet or Adhesive connections is attached to the housing. Disadvantageous with all types of fastening is that by setting effects of Plastic housing part of the original pre-load these types of fortifications are lost.
Ein weiterer Nachteil bei bisherigen Lösungen ist der zusätzliche Montageaufwand, um den endgültigen Festsitz des Trägers des Bimetallauslösers im Gehäuse zu erreichen (Einsetzen der Bimetallauslöser samt Träger in das Gehäuse, Positionieren der Träger, Zuführen der Befestigungsmittel, Erzeugen der notwendigen Vorspannung oder Aushärten des Klebstoffs).Another disadvantage with previous solutions is the additional one Assembly effort to the final tight fit of the wearer of the bimetallic release in the housing (insert the Bimetallic release including carrier in the housing, positioning the carrier, feeding the fasteners, generating the necessary pretension or hardening of the adhesive).
Der Erfindung liegt die Aufgabe zugrunde, bei Reduzierung der Montagezeit des Trägers eines Bimetallauslösers eine mindestens ebenso gute Verbindung wie mit bisherigen Befestigungsmitteln zu erhalten.The invention has for its object in reducing the Installation time of the carrier of a bimetallic release is at least one connection as good as with previous fasteners to obtain.
Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der Träger in Form einer Klemmverbindung in das Gehäuse eingepreßt ist. Dadurch reduziert sich der Montageaufwand und es ist eine mindestens ebenso gute Verbindung des Trägers mit dem Gehäuse geschaffen, die auch durch externe Belastung, z. B. an der Anschlußklemme, und Setzeffekte des Kunststoffgehäuses ihren ursprünglichen Festsitz beibehält.The problem is solved according to the invention characterized in that the carrier in the form of a clamp connection in the Housing is pressed. This reduces the assembly effort and it is at least as good a connection of the Carrier created with the housing, which is also external Load, e.g. B. at the terminal, and set effects of Plastic housing retains its original tight fit.

Fig. 1 bzw. Fig. 2 zeigt das thermoplastische Gehäuse der Heizkammer 1 einer derartigen Schutzeinrichtung, in das je Phase ein Bimetallauslöser mit Träger nach Fig. 4 eingepreßt ist.Fig. 1 and Fig. 2 shows the thermoplastic housing Heating chamber 1 of such a protective device, in each Phase a bimetallic release with carrier according to Fig. 4 pressed is.
Die axiale Einschubtiefe des Trägers 2 ist dabei durch den
spritztechnisch bestimmten Anschlagpunkt 3 des Klemmanschlusses
4 am Gehäuse der Heizkammer 1 bestimmt.The axial insertion depth of the
In dem thermoplastisch verstärkten Gehäuse der Heizkammer 1
der Schutzeinrichtung befinden sich pro Phase zwei gegenüberliegende
Nuten 5, die ein definiertes Untermaß bezüglich der
Breite (Anschlagpunkt 6 zu gegenüberliegendem Anschlagpunkt
6) und der Materialdicke 7 des Trägers 2 aufweisen, um somit
einen besseren Festsitz zu erhalten. Bei Einsatz des Trägers
nach Fig. 4 sorgen Klemmverbindungen der angefasten Klemmlaschen
8 des Klemmschenkels 9 in Taschen des Gehäuses 10 für
zusätzliche Stabilität. Diese Klemmschenkel 9 liegen parallel
zu dem mit Bimetallstreifen 11 umwickelten Trägern 2. Träger
2 nach Fig. 5 ohne Klemmschenkel werden verwendet, wenn keine
Belastung des Trägers 2 in Form von parasitären Torsionsmomenten
seitens des Klemmanschlusses 4 und/oder des Bimetallauslösers
(Fig. 4 oder 5) auftreten. Eine weitere Maßnahme,
um die Auswirkung der Torsionsmomente auf den Festsitz
zu verringern, liegt in der Ausbildung des Trägers 2 in taillierter
Form 12.In the thermoplastic reinforced housing of the heating chamber 1
the protective device has two opposite ones per
Weniger als drei Anlagepunkte 6 des Trägers 2 an der Nutwand

Verkanten des Trägers 2 in der Nut 5 führen, bevor der Träger
2 seine Endstellung bzw. der Klemmanschluß 4 seinen Anschlagpunkt
3 gemäß Fig. 3 erreicht hat.Less than three

4 zur Begrenzung der axialen Einschubtiefe gestatten
eine zügige Montage und einen guten und dauerhaften Festsitz
