Abstract

The present disclosure refers to a miniature relay with a spring bracket serving for mounting a magnet coil and spring contact bank. The base of the spring bracket is provided with plug or solder connections towards the outside, with a view to providing the most compact construction possible with a simultaneous, far-reaching separation of plug or solder connections for the coil winding and a contact bank. It is also within the context of the present invention that the longitudinal axis of the magnet coil is arranged perpendicularly to the longitudinal axis of the spring contact bank.

Description

Die vorliegende Erfindung bezieht sich auf ein Kleinstrelais mit einem der Halterung der Magnetspule und des Federkontaktsatzes dienenden Federbock, dessen Bodenwandung nach außen hin mit Steck- oder Lötanschlüssen versehen ist.The present invention relates to a small relay with a spring bracket for holding the magnetic coil and the spring contact set, the bottom wall of which is provided on the outside with plug or solder connections.

Der Durchführung von Schaltfunktionen dienende Relais werden in der Regel stehend eingebaut, wobei der FederKontaktsatz parallel zur Magnetspule angeordnet ist. Der im Bereich des einen Endes der Magnetspule angeordnete, schwenkbare Anker ist demzufolge im Bereich seines Gelenkpunktes mit einem abgewinkelten Fortsatz versehen, welcher über entsprechende Isolierstücke auf die beweglichen Kontakte des Federkontaktsatzes wirkt.Relays used to carry out switching functions are usually installed upright, with the spring contact set arranged parallel to the solenoid. The pivotable armature arranged in the area of one end of the magnet coil is consequently provided in the area of its articulation point with an angled extension which acts on the movable contacts of the spring contact set via corresponding insulating pieces.

Aufgrund der zunehmenden Miniaturisierung von elektrischen Schaltkreisen besteht zunehmend der Wunsch nach Relais kleinerer Bauweise mit insbesondere reduzierter Einbauhöhe. Aus diesem Grunde wurden somit Kleinstrelais entwickelt, bei welchen unter Aufrechterhaltung eines parallel zu der Magnetspule angeordneten Federkontaktsatzes und senkrechter Anordnung dieser Elemente in Bezug auf die Bodenplatte des vorgesehenen Federbockes die Baulängen der Magnetspule und des parallel dazu angeordneten Federkontaktsatzes entsprechend reduziert wurden. Durch die Verkürzung der vorgesehenen Magnetspule ergab sich jedoch eine entsprechende Reduzierung der Kraft des Magnetgestells, was der Reduzierung der Gesamtbauhöhe derartiger Kleinstrelais Grenzen setzt.Due to the increasing miniaturization of electrical circuits, there is an increasing desire for relays of a smaller design with a particularly reduced installation height. For this reason, small relays were developed in which the overall lengths of the magnetic coil and the spring contact set arranged in parallel were correspondingly reduced while maintaining a spring contact set arranged parallel to the magnetic coil and perpendicularly arranging these elements with respect to the base plate of the spring bracket provided. The shortening of the magnetic coil provided, however, resulted in a corresponding reduction in the force of the magnetic frame, which places limits on the reduction in the overall height of such small relays.

Es ist somit bereits ein Kleinstrelais bekannt, bei welchem im Hinblick auf eine möglichst große Reduzierung der Bauhöhe des Relais der Einbau in entsprechende Karten mit geringem gegenseitigem Abstand möglich ist, in welchem Fall der Federkontaktsatz oberhalb der liegend angeordneten Magnetspule angeordnet ist. Bei einer derartigen Bauweise eines Kleinstrelais erweist es sich jedoch als nachteilig, daß die einzelnen Federkontakte des Federkontaktsatzes abgewinkelt ausgebildet werden müssen, wobei zudem Isolationsprobleme auftreten, weil die Leitungsanschlüsse der Magnetspule sich mit den Leitungsanschlüssen des Federkontaktsatzes kreuzen.A small relay is thus already known, in which, in order to reduce the overall height of the relay as much as possible, installation in corresponding cards with a small mutual spacing is possible, in which case the spring contact set is arranged above the solenoid arranged in a horizontal position. With such a construction of a small relay, it proves to be disadvantageous that the individual spring contacts of the spring contact set must be angled, and insulation problems also occur because the line connections of the solenoid cross with the line connections of the spring contact set.

Es ist demzufolge Aufgabe der vorliegenden Erfindung, ein Kleinstrelais mit sehr geringer Bauhöhe zu schaffen, bei welchem die im Bereich der Bodenplatte vorgesehenen Steck- oder Lötanschlüsse für die Magnetspule einerseits und für die elektrischen Kontakte andererseits getrennt angeordnet werden können, ohne daß dabei im Inneren des Kleinstrelais diagonal verlaufende Leitungsverbindungen vorgesehen werden müssen.It is therefore an object of the present invention to provide a small relay with a very low overall height, in which the plug or solder connections provided in the area of the base plate for the magnetic coil on the one hand and for the electrical contacts on the other hand can be arranged separately without the inside of the Small relay diagonal line connections must be provided.

Erfindungsgemäß wird dies dadurch erreicht, daß die Längsachse der Magnetspule senkrecht zur Längsachse des Federkontaktsatzes angeordnet ist.According to the invention, this is achieved in that the longitudinal axis of the magnet coil is arranged perpendicular to the longitudinal axis of the spring contact set.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich anhand der Unteransprüche.Advantageous developments of the invention result from the subclaims.

Entsprechend Fig. 1 weist das erfindungsgemäße Kleinstrelais nach unten hin einen Federbock 1 auf, auf welchem eine das Kleinstrelais nach außen abdichtende Haube 2 aus einem transparenten Kunststoffmaterial aufgesteckt ist. Der Federbock 1 dient als Träger für eine Magnetspule 3, welche aus einem zylindrischen Kern 4, einem aus Kunststoffmaterial bestehenden Spulenkörper 5, einer elektrischen Wicklung 6, einem außen um den Spulenkörper 5 und die Wicklung 6 herumführenden Joch 7, und einem verschwenkbaren Anker 8 aufgebaut ist.According to FIG. 1, the small relay according to the invention has a spring bracket 1 at the bottom, onto which a hood 2 made of a transparent plastic material is sealed, which seals the small relay from the outside. The spring bracket 1 serves as a support for a magnetic coil 3, which is composed of a cylindrical core 4, a coil former 5 made of plastic material, an electrical winding 6, a yoke 7 leading around the outside of the coil former 5 and the winding 6, and a pivotable armature 8 is.

Die Längsachse 9 des zylindrischen Kerns 4 der Magnetspule 3 verläuft dabei parallel zu der Bodenplatte 10 des Federbockes 1.The longitudinal axis 9 of the cylindrical core 4 of the magnet coil 3 runs parallel to the base plate 10 of the spring bracket 1.

Der aus Isoliermaterial bestehende Spulenkörper 5 der Magnetspule 3 ist im Bereich des verschwenkbaren Ankers 8 mit einem in der Näher des Federbockes 1 angeordneten, blockförmigen Ansatz 11 versehen, welcher nach oben hin mit einer querverlaufenden Nut 12 versehen ist, in welcher der verschwenkbare Anker 8 zu liegen gelangt. In diese Nut 12 ragt von der Außenseite her eine Nase 13, wobei diese Nase 13 in Bezug auf die Stirnfläche des Jochs 7 derart nach unten versetzt ist, daß unter den elastischen Eigenschaften des blockförmigen Ansatzes 11 des Spulenkörpers 5 der schwenkbare Anker 8 im Ruhezustand in die von der Stirnfläche des zylindrischen Kerns 4 abgehobene Position geschwenkt wird. Mit Hilfe des blockförmigen Ansatzes 11 des Spulenkörpers 5 und der in die Nut 12 ragenden Nase wird somit gleichzeitig das Gelenk und die Abhebefeder für den schwenkbaren Anker 8 gebildet.The coil body 5 of the magnetic coil 3, which is made of insulating material, is provided in the region of the pivotable armature 8 with a block-shaped extension 11 which is arranged in the vicinity of the spring bracket 1 and which is provided with a transversely extending groove 12 in which the pivotable armature 8 is closed came to lie. In this groove 12 protrudes from the outside of a nose 13, which nose 13 is offset in relation to the end face of the yoke 7 in such a way that under the elastic properties of the block-shaped extension 11 of the coil body 5, the pivotable armature 8 in the idle state in the position lifted from the end face of the cylindrical core 4 is pivoted. With the help of the block-shaped extension 11 of the coil former 5 and the nose projecting into the groove 12, the joint and the lifting spring for the pivotable armature 8 are thus formed at the same time.

Der in Bezug auf die Bodenplatte 10 des Federbocks 1 senkrecht angeordnete, verschwenkbare Anker weist an seinem oberen, freien Ende eine rechteckige Öffnung 14 auf, in welche ein Fortsatz 15 eines flach ausgebildeten Betätigungssteges 16 hineinragt. Dieser Beätigungssteg 16 führt dabei oberhalb der Magnetspule 3 auf die andere Seite des Kleinstrelais, an welcher Stelle der Federkontaktsatz 17 angeordnet ist. Dieser Federkontaktsatz 17 besteht dabei unter Berücksichtigung von Fig. 2 aus zwei Umschaltkontaktsätzen 18,19, welche gemeinsam mit Hilfe des Betätigungssteges 16 aktivierbar sind. Der Betätigungssteg 16 weist zu diesem Zweck zwei auf der gegenüberliegenden Seite des Fortsatzes 15 angeordnete Stegabschnitte 20,21 auf, welche mit entsprechenden Fortsätzen 22,23 versehen sind, die durch rechteckige Öffnungen 24,25 der Umschaltfedern 26,27 der beiden Umschaltkontaktsätze 18,19 hindurchragen. Die beiden Umschaltfedern 26,27 sowie die parallel dazu angeordneten Ruhekontaktträger 28,29 und Arbeitskontaktträger 30,31 sind im oberen Bereich mit Kontaktstücken 32 versehen, von welchen jeweils zwei in Abhängigkeit der Schwenkposition der Umschaltfedern 26,27 in Berührung bringbar sind, wodurch wahlweise eine elektrische Verbindung der Umschaltfedern 26,27 mit den Ruhekontaktträgern 28,29 oder den Arbeitskontaktträger 30,31 herstellbar ist. Die durch die Elemente 26-31 gebildeten Federkontaktsätze sind nach unten hin mit Steck- bzw. Lötanschlüssen 33 bis 35 versehen, wobei diese Steck- bzw. Lötanschlüsse 33 bis 35 mechanisch innerhalb des Federbockes 1 positionsmäßig fixiert sind. Diese Positionierung der Steck- bzw. Lötanschlüsse 33 bis 35 innerhalb des Federbockes 1 erfolgt dabei dadurch, daß diese Steck- bzw. Lötanschlüsse 33 bis 35 während des Herstellungsvorgangs des Federbockes 1 von der Kunststoffmasse umspritzt werden.The pivotable armature, which is arranged vertically with respect to the base plate 10 of the spring bracket 1, has at its upper, free end a rectangular opening 14, into which an extension 15 of a flat actuating web 16 projects. This actuating web 16 leads above the magnetic coil 3 to the other side of the small relay, at which point the spring contact set 17 is arranged. This spring contact set 17, taking into account FIG. 2, consists of two changeover contact sets 18, 19, which can be activated together with the aid of the actuating web 16. For this purpose, the actuating web 16 has two arranged on the opposite side of the extension 15 Web sections 20,21, which are provided with corresponding extensions 22,23, which protrude through rectangular openings 24,25 of the changeover springs 26,27 of the two changeover contact sets 18,19. The two changeover springs 26, 27 and the normally closed contact carrier 28, 29 and make contact carrier 30, 31 are provided in the upper region with contact pieces 32, two of which can be brought into contact depending on the pivoting position of the changeover springs 26, 27, thereby optionally one electrical connection of the changeover springs 26, 27 to the normally closed contact carriers 28, 29 or the working contact carrier 30, 31 can be established. The spring contact sets formed by the elements 26-31 are provided at the bottom with plug or solder connections 33 to 35, these plug and solder connections 33 to 35 being mechanically fixed in position within the spring bracket 1. This positioning of the plug or solder connections 33 to 35 within the spring bracket 1 takes place in that these plug and solder connections 33 to 35 are extrusion-coated during the manufacturing process of the spring bracket 1.

Die aus den einzelnen Federkontakten 26 bis 31 bestehenden Federkontaktsätze 17 sind entsprechend der vorliegenden Erfindung derart angeordnet, daß die Längsachse des Federkontaktsatzes 17 senkrecht zur Längsachse 9 des zylindrischen Kerns 4 der Magnetspule 3 verläuft. Die einzelnen Federkontakte 26 bis 31 können somit im wesentlichen senkrecht durch die Bodenplatte 10 durchgeführt werden, wobei jedoch die Steck- bzw. Lötanschlüsse 34 der Umschaltfedern 26,27 unter Ausbildung einer Z-förmigen Konfiguration durch die Bodenplatte 10 des Federbockes 1 hindurchgeführt werden, während die beiden Steck- bzw. Lötanschlüsse 33 der auf der Seite der Magnetspule 3 zu liegen gelangenden Ruhekontaktträger 28,29 entsprechend der Darstellung unter Verwendung einer diagonalen Versetzung hindurchgeführt sind, wodurch erreicht werden kann, daß unter Aufrechterhaltung eines geringen Abstandes zwischen den einzelnen Kontaktfedern 26-31 die dazugehörigen Steck- bzw. Lötanschlüsse 33 bis 35 auf der Außenseite des Federbockes 1 einen relativ hohen, gegenseitigen Abstand besitzen, so daß im Hinblick auf die geforderten Isolierungseigenschaften ausreichend große Kriechstrecken zwischen den einzelnen Steck- bzw. Lötanschlüssen 33 bis 35 vorhanden sind.The spring contact sets 17 consisting of the individual spring contacts 26 to 31 are arranged according to the present invention such that the longitudinal axis of the spring contact set 17 extends perpendicular to the longitudinal axis 9 of the cylindrical core 4 of the magnet coil 3. The individual spring contacts 26 to 31 can thus be carried out essentially vertically through the base plate 10, but the plug or solder connections 34 of the changeover springs 26, 27 are guided through the base plate 10 of the spring bracket 1 while forming a Z-shaped configuration, while the two plug or solder connections 33 on the side of Magnetic coil 3 to rest resting contact carrier 28, 29 are passed according to the illustration using a diagonal offset, whereby it can be achieved that while maintaining a small distance between the individual contact springs 26-31 the associated plug or solder connections 33 to 35 on the Outside of the spring bracket 1 have a relatively high, mutual distance, so that there are sufficiently large creepage distances between the individual plug or solder connections 33 to 35 in view of the required insulation properties.

Im Hinblick auf eine Verbesserung der elektrischen Isoliereigenschaften zwischen den beiden Umschaltkontaktsätzen 18 und 19 ist gemäß Fig. 2 eine vorgesehene Zwischenwand 36 vorgesehen, welche durch eine entsprechende Anformung innerhalb des Federbockes 1 gebildet ist. Entsprechend Fig. 4 ragt diese durch den Federbock 1 gebildete Zwischenwand 36 bis in den Bereich der Innenwandung der Haube 2, wodurch zusätzlich eine gewisse Führung des mit den beiden Stegabschnitten 20,21 versehenen Betätigungssteges 16 erreicht werden kann. Der Federbock 1 ist zusätzlich mit zwei nach oben ragenden Ansätzen 37,38 versehen, welche eine gute Positionierung der Ruhe- bzw. Arbeitskontaktträger 28 bis 31 gewährleisten.With a view to improving the electrical insulating properties between the two changeover contact sets 18 and 19, an intermediate wall 36 is provided according to FIG. 2, which is formed by a corresponding molding within the spring bracket 1. 4, this intermediate wall 36 formed by the spring bracket 1 extends into the region of the inner wall of the hood 2, as a result of which a certain guidance of the actuating web 16 provided with the two web sections 20, 21 can also be achieved. The spring bracket 1 is additionally provided with two upwardly projecting lugs 37, 38, which ensure good positioning of the rest or working contact carriers 28 to 31.

Entsprechend Figuren 1 und 3 dient der an dem Spulenkörper 5 vorgesehene blockförmige Ansatz 11 zusätzlich der Halterung zweier Steck- bzw. Lötanschlüsse 39,40, an welchen die Enden der elektrischen Wicklung 6 beispielsweise durch Anlöten befestigt sind.According to FIGS. 1 and 3, the block-shaped extension 11 provided on the coil former 5 additionally serves to hold two plug or solder connections 39, 40, to which the ends of the electrical winding 6 are fastened, for example by soldering.

Diese Steck- bzw. Lötanschlüsse 39,40 sind dabei winkelförmig ausgelegt, wobei die äußeren Enden durch entsprechende Ausnehmungen innerhalb der Bodenplatte 10 des Federbockes 1 nach außen ragen.These plug or solder connections 39, 40 are angular in design, the outer ends being formed by corresponding recesses within the base plate 10 of the Protruding spring bracket 1 outwards.

Entsprechend Figuren 3 und 4 ist das erfindungsgemäße Kleinstrelais zusätzlich mit einem entlang der Mittelebene des Relais angeordneten Steck- bzw. Lötanschluß 41 versehen, welcher als Erdungsanschluß für das betreffende Relais dient. Anhand von Figur 4 ist schließlich noch erkennbar, daß die Steck- bzw. Lötanschlüsse 33 bis 35 der beiden Umschaltkontaktsätze 18,19 seitlich nach außen versetzt durch die Bodenplatte 10 des Federbocks 1 hindurch geführt sind, was ebenfalls der Verbesserung der elektrischen Isoliereigenschaften zwischen den einzelnen Steck- bzw. Lötanschlüssen 33 bis 35 dient.According to FIGS. 3 and 4, the small relay according to the invention is additionally provided with a plug or solder connection 41 which is arranged along the center plane of the relay and which serves as an earth connection for the relay in question. Finally, it can be seen from FIG. 4 that the plug or solder connections 33 to 35 of the two changeover contact sets 18, 19 are guided laterally offset outwards through the base plate 10 of the spring bracket 1, which also improves the electrical insulation properties between the individual Plug or solder connections 33 to 35 is used.

Während entsprechend Figur 1 die noch erforderliche Ankerfeder des verschwenkbaren Ankers 8 mit Hilfe der in die Nut 12 ragenden Nase 13 des blockförmigen Ansatzes 11 gebildet ist, so kann diese Feder auch durch einen durch das Isoliermaterial des Ansatzes 11 gebildeten Federschenkel 44 (Fig. 8,9) erreicht werden, welcher auf die äußere Fläche eines im Bereich des Gelenkpunktes abgewinkelt ausgebildeten Ankers drückt. Anstelle eines derartigen, aus Kunststoffmaterial bestehenden, Federlappens kann jedoch ebenfalls ein aus Metall gefertigtes Winkelstück 43 (Fig. 6,7) vorgesehen sein, welches in einen entsprechenden Schlitz des blockförmigen Ansatzes aus Isoliermaterial bestehenden Hohlkörpers eingesetzt ist.1, the still required anchor spring of the pivotable armature 8 is formed with the aid of the nose 13 of the block-shaped extension 11 protruding into the groove 12, this spring can also be formed by a spring leg 44 formed by the insulating material of the extension 11 (FIG. 8, 9) can be achieved, which presses on the outer surface of an anchor which is angled in the region of the articulation point. Instead of such a spring tab made of plastic material, however, an angle piece 43 (FIG. 6, 7) made of metal can also be provided, which is inserted into a corresponding slot in the block-shaped extension made of insulating material.

Im Bereich der vorliegenden Erfindung können fernerhin die im Bereich des Betätigungssteges 16 vorgesehenen Innenwandungen der Haube 2 und die unterhalb des Betätigungssteges 16 liegenden Flächen des Federbocks 1 mit vorspringenden Ansätzen 42 versehen werden, welche im Abstand zum Betätigungssteg 16 angeordnet sind, und dem Betätigungssteg 16 eine gewisse Führung verleihen und verhindern, daß der Betätigungssteg in Schwingungen geraten kann, falls von außen her auf das Kleinstrelais Vibrationen ausgeübt werden.In the area of the present invention, the inner walls of the hood 2 provided in the area of the actuating web 16 and the surfaces of the spring bracket 1 below the actuating web 16 can also be provided with projecting projections 42, which are arranged at a distance from the actuating web 16, and the like Actuating web 16 give a certain guidance and prevent the operating web from vibrating if vibrations are exerted on the small relay from the outside.

Im Rahmen der vorliegenden Erfindung kann es sich schließlich noch als zweckmäßig erweisen, wenn auf dem Betätigungssteg eine Kontaktbrücke und/oder ein Permanentmagnet angeordnet sind, wobei diese Elemente in Verbindung mit feststehenden Kontaktstücken oder einem Reed-Schalter das Schließen oder Öffnen eines oder weiterer Stromkreise hervorrufen können.In the context of the present invention, it can finally prove to be expedient if a contact bridge and / or a permanent magnet are arranged on the actuating web, these elements, in conjunction with fixed contact pieces or a reed switch, causing the closing or opening of one or more circuits can.

Vorteil der vorgeschlagenen erfindungsgemäßen Lösung ist, daß sich die Steuerstrom- und Schaltstromkreise sich nicht kreuzen und daß eine geringe Montagefläche bei kleiner Bauhöhe auf der Leiterplatte erreicht wird. Nachdem der Spulenkörper als Halteelement für den Anker dient, und der Spulenkörper tragendes Element für das Magnetgestell ist, kann die geforderte Miniaturisierung erreicht werden, ohne daß die Magnetkraft herabgesetzt werden muß, wie dies bei Kleinstrelais vergleichbarer Größe der Fall ist. Überdies fällt die bekannterweise vorhandene Ankerhaltefeder fort, so daß sich auch eine einfache Einsteck-Montage für den Anker ergibt. Nachdem der Anker bezüglich der Spule den Kontaktfedern genau gegenüber liegt, ergeben sich weitestmögliche Luft- und Kriechstrecken zwischen Magnet- und Kontaktsystem von etwa 8 bis 14 mm, so daß ein solches Relais höchsten Sicherheitsanforderungen, z.B. denen des Untertage-Bergbaus, entspricht.The advantage of the proposed solution according to the invention is that the control and switching circuits do not cross each other and that a small mounting area is achieved with a small overall height on the circuit board. After the coil body serves as a holding element for the armature and the coil body is a supporting element for the magnet frame, the required miniaturization can be achieved without the magnetic force having to be reduced, as is the case with small relays of comparable size. In addition, the known anchor retaining spring is omitted, so that there is also a simple plug-in assembly for the anchor. After the armature with respect to the coil lies exactly opposite the contact springs, the greatest possible air and creepage distances between the magnet and contact system of about 8 to 14 mm result, so that such a relay meets the highest safety requirements, e.g. corresponds to that of underground mining.
