Description

Elektromagnetisches Relais und Verfahren zu dessen Herstellung Electromagnetic relay and process for its manufacture
Die Erfindung betrifft ein elektromagnetisches Relais mit fol¬ genden Merkmalen:The invention relates to an electromagnetic relay with the following features:
- Ein Gehäuse besitzt eine Kappe mit einer im wesentlichen ge¬ schlossenen Oberseite, geschlossenen Seitenwänden und einer offenen, durch ein Bodenteil verschließbaren Bodenseite,A housing has a cap with an essentially closed upper side, closed side walls and an open bottom side which can be closed by a base part,
- in dem Gehäuse sind ein Kontaktsystem mit herausgeführten Kontaktanschlußelementen sowie ein Magnetsystem angeordnet, dessen Spule benachbart zur geschlossenen Oberseite der Kappe liegt, und - die Wicklungsenden der Spule sind jeweils mit in einem Spu¬ lenkörper verankerten Stützelementen verbunden, welche ihrer¬ seits elektrisch leitend mit durch die Bodenseite herausge¬ führten Spulenanschlußelementen verbunden sind. Außerdem betrifft die Erfindung ein Herstellungsverfahren für ein derartiges Relais.- A contact system with lead-out contact connection elements and a magnet system are arranged in the housing, the coil of which is adjacent to the closed top of the cap, and - The winding ends of the coil are each connected to support elements anchored in a coil body, which in turn is electrically conductive with are connected through the bottom side of the coil connecting elements. The invention also relates to a manufacturing method for such a relay.
Ein Relais mit dem genannten Aufbau ist beispielsweise aus der DE-A-38 35 105 bekannt. Durch die dort vorgesehene Anordnung der Spule oberhalb des Kontaktsystems im geschlossenen oberen Bereich des Gehäuses wird ein schmaler Aufbau erreicht. Durch die Anordnung der Kontaktelemente in der Nähe der Anschlußseite im unteren Teil des Gehäuses werden auch kurze elektrische Ver¬ bindungen zwischen den Kontakten und den zugehörigen Anschlu߬ stiften gewährleistet, was nicht nur eine Ersparnis an Material und Bearbeitungsschritten ermöglicht, sondern auch Vorteile hinsichtlich der Wärmeableitung und der Isolierung zwischen den Kontaktelementen und dem Magnetsystem bringt. Deshalb wird die¬ se Bauform bevorzugt für Starkstrom- und Netzrelais eingesetzt.A relay with the structure mentioned is known for example from DE-A-38 35 105. The arrangement of the coil provided there above the contact system in the closed upper region of the housing achieves a narrow construction. The arrangement of the contact elements in the vicinity of the connection side in the lower part of the housing also ensures short electrical connections between the contacts and the associated connection pins, which not only enables savings in material and processing steps, but also advantages in terms of heat dissipation and brings the insulation between the contact elements and the magnet system. For this reason, this design is preferably used for heavy current and mains relays.
Durch die Anordnung der Spule im oberen Bereich des Gehäuses ist es allerdings erforderlich, die Spulenanschlußelemente über eine verhältnismäßig lange Strecke bis zur Anschlußseite des Relais zu führen, wobei aber die Isolierung zu den Eisenkreis¬ teilen des Magnetsystems und zu den Kontaktelementen gewährlei¬ stet werden muß. Insbesondere beim Einsatz des Relais an höhe¬ ren Spannungen erfordert diese Isolierung, entweder in Form entsprechender Ansätze des Spulenkörpers oder in Form zusätzli¬ cher Isolierteile, einen nicht unbeachtlichen Raum im Gehäuse.Due to the arrangement of the coil in the upper region of the housing, however, it is necessary to connect the coil connection elements over a relatively long distance to the connection side of the Relay to lead, but the insulation to the Eisenkreis¬ parts of the magnet system and to the contact elements must be guaranteed. Particularly when the relay is used at higher voltages, this insulation, either in the form of corresponding approaches of the coil former or in the form of additional insulating parts, requires a not inconsiderable space in the housing.
Aufgabe der Erfindung ist es, ein Relais der eingangs genannten Art sowie ein Herstellverfahren für dieses Relais anzugeben, bei dem unter Beibehaltung des grundsätzlichen Aufbaus eine einfache und platzsparende Verbindung von den Wicklungsenden der Spule zur Anschlußseite des Relais ermöglicht wird. Insbe¬ sondere soll dabei die Isolation zwischen Spulenanschlußelemen- ten und Magnetkreis sowie Kontaktelementen ohne zusätzlichen Raumbedarf sichergestellt werden.The object of the invention is to provide a relay of the type mentioned and a manufacturing method for this relay, in which a simple and space-saving connection from the winding ends of the coil to the connection side of the relay is made possible while maintaining the basic structure. In particular, the insulation between the coil connection elements and the magnetic circuit and contact elements should be ensured without requiring additional space.
Zur Lösung dieser Aufgabe besitzt ein erfindungsgemäßes Relais die folgenden zusätzlichen Merkmale:To achieve this object, a relay according to the invention has the following additional features:
- Die Spulenanschlußele ente sind jeweils in einer Seitenwand der Kappe isoliert von der Bodenseite bis in den Bereich der- The Spulenanschlußele ducks are each isolated in a side wall of the cap from the bottom to the area
Oberseite der Kappe geführt und münden in einer nach außen offenen Vertiefung der Kappenoberseite,Out the top of the cap and open into a recess on the top of the cap open to the outside,
- die Stützelemente des Spulenkörpers sind in Stecköffnungen zur Kappenoberseite geführt und münden ebenfalls jeweils in einer der Vertiefungen und- The support elements of the coil body are guided in plug openings to the top of the cap and also each open into one of the recesses and
- in jeder Vertiefung ist das jeweilige Ende eines Stützelemen¬ tes mit dem Ende eines Spulenanschlußelementes leitend ver¬ bunden.- In each recess, the respective end of a support element is conductively connected to the end of a coil connecting element.
Bei dem erfindungsgemäßen Relais sind also die Spulenanschlu߬ elemente isoliert unmittelbar in der Wand der Kappe geführt, vorzugsweise eingebettet. Dadurch ist innerhalb des Gehäuserau¬ mes weder Platz für diese Spulenanschlußelemente selbst noch für zusätzliche Isolierwände erforderlich. Der Raumbedarf ist somit allein durch die Ausdehnung des Magnetsystems und des Kontaktsystems bestimmt. Die leitende Verbindung zwischen den Enden des jeweiligenIn the relay according to the invention, the coil connecting elements are thus guided in an isolated manner, preferably embedded, in the wall of the cap. As a result, neither space for these coil connecting elements themselves nor for additional insulating walls is required within the housing space. The space requirement is thus determined solely by the expansion of the magnet system and the contact system. The conductive connection between the ends of each
Stützelementes und des zugehörigen Spulenanschlußelementes kann grundsätzlich auf verschiedene Weise mit üblichen Verfahren hergestellt werden. In Betracht kommen dabei Schweißverbindun- gen oder Lötverbindungen, wenn die Konstruktion so gestaltet werden kann, daß die zu verbindenden Enden für Schweißelektro¬ den oder für Lötvorrichtungen zugänglich sind und gegebenen¬ falls auch die Beständigkeit gegen die Löttemperatur in der Um¬ gebung der Lötstelle gewährleistet ist. Besonders vorteilhaft ist jedoch eine Verbindung mittels eines Leitklebstoffes, der in die jeweilige Vertiefung eingebracht wird und bei relativ niedriger Temperatur aushärtet. Um die Isolation der Verbin¬ dungsstelle nach außen zu gewährleisten, wird vorzugsweise auf die Verbindungsstelle bzw. auf den Leitklebstoff eine Isolier- stoffschicht aufgebracht, die die Vertiefung nach außen ab¬ schließt.Support element and the associated coil connecting element can in principle be manufactured in various ways using conventional methods. Welded connections or soldered connections come into consideration here if the construction can be designed in such a way that the ends to be connected are accessible for welding electrodes or for soldering devices and, if appropriate, also ensure the resistance to the soldering temperature in the vicinity of the soldering point is. However, a connection by means of a conductive adhesive, which is introduced into the respective depression and cures at a relatively low temperature, is particularly advantageous. In order to ensure the insulation of the connection point from the outside, an insulating layer is preferably applied to the connection point or to the conductive adhesive, which layer closes off the recess from the outside.
Ein bevorzugtes Verfahren zur Herstellung des Relais besteht im wesentlichen aus folgenden Schritten: - Die Kappe wird mit den in mindestens einer Seitenwand einge¬ betteten Spulenanschlußelementen, mit Vertiefungen an der Kappenoberseite im Bereich der Enden der Spulenanschlußele¬ mente und mit Stecköffnungen im Bereich der Vertiefungen aus¬ geformt , - in die offene Kappe werden das Magnetsystem und das Kontakt¬ system eingesetzt, wobei im Spulenkörper eingebettete Stütz¬ elemente mit freien Enden in die Stecköffnungen der Kappe eingesteckt werden, und - in den Vertiefungen an der Kappenoberseite wird je ein Stütz- element mit einem Spulenanschlußelement leitend verbunden.A preferred method for producing the relay essentially consists of the following steps: - The cap is made with the coil connection elements embedded in at least one side wall, with depressions on the top of the cap in the area of the ends of the coil connection elements and with plug-in openings in the area of the depressions ¬ shaped, - the magnet system and the contact system are inserted into the open cap, with support elements embedded in the coil body with free ends being inserted into the plug-in openings of the cap, and - in the recesses on the top of the cap, one support element each conductively connected to a coil connecting element.
Soll das Gehäuse waschdicht abgeschlossen werden, so ist es von Vorteil, vor der Herstellung der leitenden Verbindung in den Vertiefungen die Bodenseite der Kappe mit Vergußmasse abzudich- ten, wobei bis zur Aushärtung der Vergußmasse die Stecköffnun¬ gen der Kappe als Lüftungslöcher dienen können. Durch Einbrin¬ gen von Leitklebstoff in die Vertiefungen können dann jeweils die Stützelemente und Spulenanschlußelemente leitend verbunden, zugleich aber auch die Stecköffnungeπ dicht verschlossen wer¬ den. Durch Aufbringen von Isolierstoff auf die leitende Verbin¬ dung in den Vertiefungen können diese Vertiefungen zusätzlich abgedichtet und die leitenden Verbindungen nach außen isoliert werden.If the housing is to be sealed in a wash-tight manner, it is advantageous to seal the bottom side of the cap with potting compound in the depressions before the conductive connection is made, the plug openings of the cap being able to serve as ventilation holes until the potting compound has hardened. By introducing conductive adhesive into the depressions, it is then possible in each case the support elements and coil connection elements are conductively connected, but at the same time the plug openings are also tightly closed. By applying insulating material to the conductive connection in the depressions, these depressions can be additionally sealed and the conductive connections can be insulated from the outside.

Das in den Figuren 1 bis 3 gezeigte Relais besitzt ein Gehäuse, das aus einer Kappe 1 mit einer geschlossenen Oberseite 2 sowie ringsum geschlossenen Seitenwänden 3 und einem als Sockel in die offene Bodenseite 4 der Kappe 1 eingesetzten Kontaktträger 5. Im unteren, der Bodenseite benachbarten Bereich des Gehäuses sind am Kontaktträger 5 befestigte Kontaktelemente 6 und 7 mit ihren Anschlußelementen 6a und 7a befestigt. Im oberen, der ge¬ schlossenen Oberseite 2 der Kappe benachbarten Bereich ist ein Magnetsystem mit einer Spulenwicklung 8, einem Kern 9, einem Joch 10 und einem Anker 11 angeordnet, wobei der letztere über ein Betätigungselement 12 das Kontaktelement 7 betätigt. Der Aufbau und die Funktion des Relais an sich sind weiter nicht Gegenstand dieser Anmeldung und werden deshalb auch nicht im einzelnen beschrieben.The relay shown in FIGS. 1 to 3 has a housing which consists of a cap 1 with a closed top 2 and all around closed side walls 3 and a contact carrier 5 used as a base in the open bottom side 4 of the cap 1 In the area of the housing, contact elements 6 and 7 fastened to the contact carrier 5 are fastened with their connecting elements 6a and 7a. A magnet system with a coil winding 8, a core 9, a yoke 10 and an armature 11 is arranged in the upper area adjacent to the closed top 2 of the cap, the latter actuating the contact element 7 via an actuating element 12. The structure and function of the relay itself are not the subject of this application and are therefore not described in detail.
Die Spulenwicklung 8 sitzt auf einem Spulenkörper 13, in dessen Flansch 14 zwei drahtförmige Stützelemente 15 und 16 zum Anwik- keln und Kontaktieren der Wicklungsenden verankert sind. Diese Stützelemente 15 und 16 sind mit ihren freien Enden jeweils durch eine Stecköffnung 17 in eine von zwei Vertiefungen 18 an der Oberseite der Kappe 1 geführt. Diese Vertiefungen 18 sind in die Oberseite 2 der Kappe eingeformt und zunächst nach außen offen, mit dem Gehäuseinneren jedoch nur über die Stecköffnun- gen 17 verbunden.The coil winding 8 is seated on a coil former 13, in the flange 14 of which two wire-shaped support elements 15 and 16 are anchored for winding and contacting the winding ends. These support elements 15 and 16 are each with their free ends passed through a plug opening 17 into one of two recesses 18 on the top of the cap 1. These depressions 18 are molded into the top 2 of the cap and initially open to the outside, but are only connected to the interior of the housing via the plug openings 17.
Außerdem sind in einer der Seitenwände 3 bzw. in rippenartigen Verdickungen 19 in zwei Ecken der Seitenwand zwei Spulenan¬ schlußelemente 20 eingebettet, die jeweils einen zur Bodenseite herausgeführten Anschlußstift 20a sowie einen jeweils in eine Vertiefung 18 an der Kappenoberseite mündendes Verbindungsende 20b aufweisen.In addition, two coil connection elements 20 are embedded in one of the side walls 3 or in rib-like thickenings 19 in two corners of the side wall, each of which has a connecting pin 20a led out to the bottom side and a connecting end 20b opening into a recess 18 on the top of the cap.
In die Vertiefungen 18 ist von außen her Leitklebstoff 21 ein- gefüllt, welcher die Stützelemente 15 und die Spulenanschlu߬ elemente 20 jeweils elektrisch leitend verbindet. Über den Leitklebstoff 21 ist eine Isolierstoffschicht 22 aufgebracht, welche das Gehäuse nach oben abschließt und isoliert.Conductive adhesive 21 is filled into the recesses 18 from the outside and connects the support elements 15 and the coil connection elements 20 in each case in an electrically conductive manner. An insulating material layer 22 is applied over the conductive adhesive 21 and closes and insulates the housing from above.
Bei der Montage des Relais wird zunächst das Magnetsystem in die Kappe 1 eingesetzt und befestigt, wobei die Stützelemente 15 durch die Stecköffnungen 17 gesteckt werden. Durch Einsetzen des Kontaktsystems mit dem Träger 5 wird das Gehäuse zur Unter¬ seite abgeschlossen. Durch Aufbringen einer Schicht Vergußmasse 23 wird das Gehäuse abgedichtet, wobei die Stecköffnungen 17 als Lüftungslöcher wirken, die beim Aushärten der Vergußmasse 23 einen Druckausgleich ermöglichen. Danach wird der erwähnte Leitklebstoff 21 in die Vertiefungen 18 eingebracht, und diese werden dann nach außen durch Einbringen der Isolierstoffschicht 22 abgeschlossen.When assembling the relay, the magnet system is first inserted and fastened in the cap 1, the support elements 15 being inserted through the plug openings 17. By inserting the contact system with the carrier 5, the housing is closed on the underside. By applying a layer of potting compound 23, the housing is sealed, the plug-in openings 17 acting as ventilation holes, which enable pressure compensation when the potting compound 23 hardens. Thereafter, the aforementioned conductive adhesive 21 is introduced into the depressions 18, and these are then closed off from the outside by introducing the insulating material layer 22.
Figur 3 zeigt ein fertiges Relais in perspektivischer Darstel¬ lung. An der Kappe 1 sind die in der Oberseite vorgesehenen und mit der Isolierstoffschicht 22 verschlossenen Vertiefungen 18 erkennbar, in denen die Spulenanschlüsse in der vorher be¬ schriebenen Weise kontaktiert wurden. FIG. 3 shows a finished relay in a perspective representation. On the cap 1, the recesses 18 provided in the upper side and closed with the insulating material layer 22 can be seen, in which the coil connections have been contacted in the manner previously described.
