Abstract

A hotplate is provided on the bottom of its body with a cover plate, through which a lead is passed through an insulator. The stub-like ends of the leads are connected to the outer terminal portions of the multicore cable ends projecting from a positioning part and are squeezed at this point. The multicore cable ends are longer than conventional multicore cable ends.

Description

Die Erfindung betrifft eine Elektrokochplatte mit einem Kochplattenkörper und einem unteren Abdeckblech, durch das im Randbereich ein Isolierstück hindurchragt, aus dem die elektrischen Kochplattenanschlußleitungen stummelartig herausragen, sowie mit einem gegenüber der Kochplatte festlegbaren Positionierteil mit beabstandeten Durchgängen, in denen die flexiblen, mit Aderendhülsen versehenen Verbindungsleitungen zu ihrer Verbindung mit den stummelartigen Enden der Anschlußleitungen festgelegt sind.The invention relates to an electric hotplate with a hotplate body and a lower cover plate, through which an insulating piece protrudes in the edge area, from which the electric hotplate connection lines protrude stubbornly, and to a positioning part which can be fixed relative to the hotplate and has spaced passages in which the flexible connecting wires provided with wire end sleeves are fixed for their connection to the stub-like ends of the connecting lines.

Eine derartige Elektrokochplatte ist in der nachveröffentlichten europäischen Patentanmeldung EP-A-113 923 vorgeschlagen worden.Such an electric hotplate has been proposed in the subsequently published European patent application EP-A-113 923.

Bei diesem Vorschlag ist vorgesehen, daß das Positionierteil am Kochplattenkörper befestigbar, insbesondere aufsteckbar ist. Das Positionierteil kann eine der Zahl der Anschlußleitung entsprechende Zahl von beabstandeten Durchgängen aufweisen. Der Abstand der Durchgänge im Positionierteil kann dem Abstand der Anschlußdrähte entsprechen. Die stummelartigen Enden der Anschlußleitungen sollen nicht über die durch die Unterkante des Kochplattenkörpers gebildete Ebene vorstehen. Sie können derart abgebogen sein, daß sie sich mit den Anschlußdrähten vorzugsweise unter Bildung eines etwa rechten Winkels überkreuzen.In this proposal, it is provided that the positioning part can be attached to the hotplate body, in particular can be attached. The positioning part can have a number of spaced passages corresponding to the number of connecting lines. The distance between the passages in the positioning part can correspond to the distance between the connecting wires. The stub-like ends of the connecting lines should not protrude beyond the plane formed by the lower edge of the hotplate body. They can be bent in such a way that they preferably cross with the connecting wires to form an approximately right angle.

Diesem Vorschlag lag der Gedanke zugrunde, eine Elektrokochplatte zu schaffen, die sich zur automatischen Bestückung von Herdmulden besonders eignet.This proposal was based on the idea of creating an electric hotplate that is particularly suitable for the automatic loading of cooker hobs.

Bei dem damaligen Vorschlag war bereits vorgesehen, daß im Positionierteil die mit Aderendhülsen versehenen Verbindungsleitungen festlegbar sind. Mit den Aderendhülsen wurden dann Anschlußdrähte verbunden, die aus dem Positionierteil herausragen und mit den Anschlußleitungen der Kochplatte verbindbar sind.In the proposal at the time it was already provided that the connecting lines provided with wire end sleeves can be fixed in the positioning part. With the wire end sleeves connecting wires were then connected, which protrude from the positioning part and can be connected to the connecting lines of the hotplate.

Der Erfindung liegt die Aufgabe zugrunde, eine Elektrokochplatte der eingangs genannten Art, insbesondere eine Elektrokochplatte nach der deutschen Patentanmeldung, derart weiterzuverbessern, daß die Herstellungskosten verringert und die Anwendungsmöglichkeiten verbessert werden. Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Aderendhülsen aus dem Positionierteil auf dessen dem Isolierstück zugewandten Seite herausragen und sich mit den Enden der Anschlußdrähte überkreuzen. Es sind nach dem Vorschlag der Erfindung also keine Drähte mehr erforderlich, die an die Aderendhülsen angebracht werden müssen. Dadurch verringert sich nicht nur die Zahl der Bauteile, sondern auch die Zahl der Arbeitsschritte. Damit die Aderendhülsen aus dem Positionierteil herausragen können, ist es sinnvoll, hierzu speziell ausgebildete relativ lange Aderendhülsen zu verwenden. Die Maßnahme nach der Erfindung haben den zusätzlichen großen Vorteil, daß beim Austausch von derart ausgerüsteten Kochplatten mit den üblichen Kochplatten die Anschlußdrähte weiter verwendbar sind. Beim Auswechseln werden einfach die aus dem Positionierteil herausragenden Enden der Aderendhülsen abgezwickt, die Aderendhülse aus dem Positionierteil herausgezogen und auf die übliche Länge mit Hilfe eines Seitenschneiders o.dgl. verkürzt. Dann kann zum Austausch eine übliche Kochplatte mit Schraubanschluß eingesetzt werden.The invention has for its object to further improve an electric hotplate of the type mentioned, in particular an electric hotplate according to the German patent application, in such a way that the production costs are reduced and the possible uses are improved. To solve this problem, the invention provides that the wire end sleeves protrude from the positioning part on its side facing the insulating piece and cross with the ends of the connecting wires. According to the proposal of the invention, wires are no longer required which have to be attached to the wire end ferrules. This not only reduces the number of components, but also the number of work steps. So that the wire end sleeves can protrude from the positioning part, it makes sense to use specially designed relatively long wire end sleeves for this. The measures according to the invention have the additional great advantage that when connecting hotplates equipped in this way with the usual hotplates, the connecting wires can continue to be used. When replacing the ends of the wire end sleeves protruding from the positioning part, the wire end sleeve is pulled out of the positioning part and pulled to the usual length with the help of a side cutter or the like. shortened. A conventional hotplate with screw connection can then be used for replacement.

In Weiterbildung der Erfindung kann vorgesehen sein, daß die Aderendhülsen und die Durchgänge des Positionierteils zwei Bereiche unterschiedlichen Durchmessers aufweisen und die aus dem Positionierteil herausragenden Enden der Hülsen verquetscht sind. Durch die Bereiche unterschiedlichen Durchmessers wird gewährleistet, daß die Aderendhülsen mit den daran befestigten flexiblen Verbindungsleitungen korrekt in dem Positionierteil positioniert sind, und durch die Verquetschung wird erreicht, daß die Lage der Aderendhülsen fixiert bleibt. Durch das Verquetschen kann dafür gesorgt werden, daß sich eine besonders günstige vergrößerte Anlagefläche zwischen den Aderendhülsen und den stummelartigen Enden der Anschlußdrähte ergibt. Die Verquetschung kann so vorgenommen werden, daß die Enden der Aderendhülsen flachgedrückt werden. Es ist ebenfalls möglich, eine Verquetschung mit Hilfe einer Verbiegung durchzuführen.In a development of the invention it can be provided that the wire end sleeves and the passages of the positioning part have two areas of different diameters and the ends of the sleeves protruding from the positioning part are crimped. The areas of different diameters ensure that the wire end sleeves with the flexible connecting lines attached to them are correctly positioned in the positioning part, and the pinching ensures that the position of the wire end sleeves remains fixed. The squeezing can ensure that there is a particularly advantageous enlarged contact surface between the wire end sleeves and the stub-like ends of the connecting wires. The crimping can be done so that the ends of the ferrules are flattened. It is also possible to squeeze using a bend.

Die Erfindung sieht vor, daß der Bereich verkleinerten Durchmessers der Aderendhülsen einen etwa U- oder V-förmigen Querschnitt aufweisen kann. Derartige Aderendhülsen lassen sich aus Blechzuschnitten relativ einfach herstellen, wobei der U- bzw. V-förmige Querschnitt eine einfache Möglichkeit ergibt, den Durchmesser der Aderendhülsen in diesem Bereich kleiner zu halten. Die Verquetschung dieses Querschnitts außerhalb des Positionierteils läßt sich ebenfalls sehr einfach durchführen.The invention provides that the area of reduced diameter of the wire end sleeves can have an approximately U-shaped or V-shaped cross section. Such wire end sleeves can be produced relatively easily from sheet metal blanks, the U or V-shaped cross section providing a simple possibility of keeping the diameter of the wire end sleeves smaller in this area. The squeezing of this cross section outside the positioning part can also be carried out very easily.

In Weiterbildung kann vorgesehen sein, daß der Bereich verkleinerten Durchmessers der Aderendhülsen etwa drei mal lang ist wie der Bereich vergrößerten Durchmessers. Es hat sich herausgestellt, daß in diesem Fall die Aderendhülsen mit den üblichen Anschlußteilen verwendet werden können.In a further development it can be provided that the area of reduced diameter of the wire end ferrules is approximately three times as long as the area of enlarged diameter. It has been found that in this case the ferrules can be used with the usual connecting parts.

Besonders günstig ist es, wenn nach einem weiteren Merkmal der Erfindung das Positionierteil an dem Isolierstück festlegbar ist. Zu diesem Zweck kann das Isolierstück eine seitliche Ausnehmung aufweisen, in der das Positionierteil festlegbar ist.It is particularly favorable if, according to a further feature of the invention, the positioning part can be fixed on the insulating piece. For this purpose, the insulating piece can have a lateral recess in which the positioning part can be fixed.

Die in Fig. 1 und 2 dargestellte Kochplatte hat im wesentlichen einen Kochplattenkörper 11, der an seiner Außenseite einen Überfallrand 12 aufweist und an seiner Unterseite von einem Abdeckblech 13 abgedeckt ist. Das Abdeckblech liegt am unteren Rand 14 des Kochplattenkörpers auf und ist am hohlen Mittelbolzen mit Hilfe einer Schraube 15 befestigt. Im Abdeckblech 13 befindet sich in der Nähe des Kochplattenrandes 14 eine Vertiefung 16 mit einem darin eingesetzten Isolierstück 17. Das Isolierstück weist drei Löcher 18 auf, durch die die blanken Enden der Anschlußleitungen 19 für die im einzelnen nicht dargestellten elektrischen Heizwiderstände hindurchgeführt sind. Die Enden 20 der Anschlußleitungen 19 sind unterhalb bzw. außerhalb des Isolierstückes 17 leicht in Richtung auf die Mitte des Kochplattenkörpers abgebogen und abgeschnitten, so daß sie nicht über die durch den unteren Kochplattenrand 14 gebildete Ebene hinausragen.The hotplate shown in FIGS. 1 and 2 essentially has a hotplate body 11 which has a rim 12 on its outside and is covered by a cover plate 13 on its underside. The cover plate lies on the lower edge 14 of the hotplate body and is fastened to the hollow central bolt with the aid of a screw 15. In the cover plate 13 there is a recess 16 near the hotplate edge 14 with an insulating piece 17 inserted therein. The insulating piece has three holes 18 through which the bare ends of the connecting lines 19 for the electrical heating resistors (not shown in detail) are passed. The ends 20 of the connecting lines 19 are bent slightly below and outside the insulating piece 17 towards the center of the hotplate body and cut off so that they do not protrude beyond the plane formed by the lower hotplate edge 14.

Im Bereich des Isolierstücks 17 ist ein Positionierteil 21 angeordnet, das mit seinem kochplattenseitigen Ende 22 in eine Ausnehmung im Rand 23 des Isolierstückes 17 eingreift. Das Positionierteil 21 weist drei durchgehende Bohrungen 24 auf, die im Bereich des kochplattenfernen Endes 25 des Positionierteiles 21 einen vergrößerten Durchmesser aufweisen. Von dieser Seite her sind mit Aderendhülsen 26 versehene flexible isolierte Verbindungsleitungen 27 in das Positionierteil 21 eingeschoben. Die Form der Aderendhülsen geht aus den Fig. 3 bis 6 hervor. Die freien Enden der Aderendhülsen 26 ragen aus dem kochplattenseitigen Ende 22 des Positionierteiles 21 so weit heraus, daß sie sich mit den stummelartigen Enden 20 der Anschlußleitungen 19 kreuzen.In the area of the insulating piece 17, a positioning part 21 is arranged, which engages with its hotplate-side end 22 into a recess in the edge 23 of the insulating piece 17. The positioning part 21 has three through bores 24 which have an enlarged diameter in the region of the end 25 of the positioning part 21 remote from the hotplate. Flexible insulated connecting lines 27 provided with wire end sleeves 26 are inserted into the positioning part 21 from this side. The shape of the wire end ferrules can be seen from FIGS. 3 to 6. The free ends of the wire end sleeves 26 protrude from the hotplate end 22 of the positioning part 21 so far that they intersect with the stub-like ends 20 of the connecting lines 19.

Diese Enden der Aderendhülsen 26 sind flachgepreßt und die flachgepreßten Enden sind mit den stummelartigen Enden 20 der Anschlußleitungen verschweißt, vorzugsweise durch Kreuz-Widerstandsschweißen.These ends of the wire end sleeves 26 are pressed flat and the pressed ends are welded to the stub-like ends 20 of the connecting lines, preferably by cross-resistance welding.

Aus Fig. 3 geht die Form der Aderendhülsen 26 hervor. Die Aderendhülsen 26 besitzen einen ersten Bereich 28, der üblichen Aderendhülsen entspricht. In diesem Bereich sind die Aderendhülsen um die Verbindungsleitungen 27 verpreßt, wobei die Verpressung im äußeren Teil 29 auch die Isolierung der Verbindungsleitungen 27 erfaßt. In dem darauf folgenden Bereich 30 erfaßt die Verpressung nur den metallischen Teil der Verbindungsleitung 27, so daß hier eine gut leitende elektrische Verbindung hergestellt ist. An diesen Bereich 30 schließt sich ein stark verlängerter Bereich 31 verringerten Durchmessers an, der eine Verlängerung der Aderendhülse 26 bildet.3 shows the shape of the wire end sleeves 26. The wire end sleeves 26 have a first region 28, which corresponds to conventional wire end sleeves. In this area the wire end sleeves are pressed around the connecting lines 27, the pressing in the outer part 29 also detecting the insulation of the connecting lines 27. In the area 30 that follows, the pressing only detects the metallic part of the connecting line 27, so that a good conductive electrical connection is established here. This area 30 is followed by a greatly extended area 31 of reduced diameter, which forms an extension of the wire end sleeve 26.

Fig. 5 zeigt einen Querschnitt durch den Bereich 30, in dem eine Verpressung zwischen dem Metall der Aderendhülse 26 und dem metallischen Teil der Verbindungsleitung 27 hergestellt ist.FIG. 5 shows a cross section through the area 30 in which a compression is produced between the metal of the wire end sleeve 26 and the metallic part of the connecting line 27.

Fig. 6 zeigt den Schnitt durch den Bereich 31 verkleinerten Durchmessers, woraus zu sehen ist, daß der Querschnitt in diesem Bereich etwa U-förmig ausgebildet ist.Fig. 6 shows the section through the area 31 of reduced diameter, from which it can be seen that the cross section in this area is approximately U-shaped.

Diese neuartigen Aderendhülsen werden durch das Positionierteil 21 hindurchgesteckt und ihre freien Enden jenseits des Positionierteils 21 verpreßt.These novel wire end sleeves are inserted through the positioning part 21 and their free ends are pressed beyond the positioning part 21.

Eine Möglichkeit der Verpressung zeigt Fig. 7. Das äußere Ende der Aderendhülse 26 wird in diesem Fall zu einem ebenen Bereich 32 verpreßt, der dadurch einen größeren Durchmesser aufweist als der Bereich 31 und damit zu einer Festlegung der Aderendhülse im Positionierteil 21 dient.7 shows one possibility of pressing. The outer end of the wire end sleeve 26 is pressed in this case to a flat area 32, which thereby has a larger diameter than the area 31 and thus serves to fix the wire end sleeve in the positioning part 21.

Fig. 8 zeigt nun, wie der fläche Teil 32 mit dem senkrecht zu ihm verlaufenden Ende 20 einer Anschlußleitung 19 verbunden wird. Das Verbinden geschieht durch eine Widerstandsschweißung, es können jedoch auch andere Arten der Verschweißung durchgeführt werden.8 now shows how the flat part 32 is connected to the end 20 of a connecting line 19 running perpendicular to it. The connection is made by resistance welding, but other types of welding can also be carried out.

Bei Fig. 9 besitzt das äußere Ende 33 der Aderendhülse 26 einen Schlitz, so daß die Verpressung außerhalb des Positionierteiles 31 zu zwei parallel zueinander angeordneten ebenen Bereichen führt, zwischen denen das Ende 20 der Anschlußleitung 19 hindurchgeführt und verschweißt ist.In Fig. 9, the outer end 33 of the wire end sleeve 26 has a slot, so that the pressing outside of the positioning part 31 leads to two flat areas arranged parallel to one another, between which the end 20 of the connecting line 19 is passed and welded.

Während beim dargestellten Ausführungsbeispiel im Isolierstück 17 und im Positionierteil 21 drei Löcher 18 bzw. drei Bohrungen 24 vorhanden sind, kann die Zahl dieser Löcher bzw. Bohrungen je nach Anwendungsfall auch kleiner oder größer sein.While in the illustrated embodiment there are three holes 18 and three holes 24 in the insulating piece 17 and in the positioning part 21, the number of these holes or holes can also be smaller or larger depending on the application.
