Description

Gebiet der ErfindungField of the invention

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Spulenbaugruppe sowie auf diese Spulenbaugruppe selbst, insbesondere zur Verwendung in einem Relais, mit einem isolierenden Spulenkörper als Wickelträger, mit einer auf dem Spulenkörper gewickelten Spule und einem Anschlussblock an dem Spulenflansch zum Anschließen der Wickeldrahtenden an Anschlussstifte.The invention relates to a method for producing a coil assembly and to this coil assembly itself, in particular for use in a relay, with an insulating bobbin as a coil carrier, with a coil wound on the bobbin and a terminal block on the coil flange for connecting the winding wire ends to pins ,

Hintergrund der ErfindungBackground of the invention

Die EP 2 187 418 A2 zeigt ein Relais, das ein Relaiskernelement mit einem Magnetkern, einem Joch, einer Spule und einem isolierenden Spulenkörper in Form zweier Rahmen aufweist, von denen der zweite Rahmen einen Spulenflansch mit einem Anschlussblock bildet, der über die Spulenachse hinausragt und in welchem zwei Anschlussstifte für die Wickeldrahtenden befestigt sind. Bei dieser Konstruktion des Relaiskernelementes ergibt sich eine Baulänge, die über die Baulänge des eigentlichen Spulenkörpers hinausreicht, wenn die Länge der Spulenachse von Spulenflansch zu Spulenflansch in Betracht gezogen wird.The EP 2 187 418 A2 shows a relay having a relay core element with a magnetic core, a yoke, a coil and an insulating bobbin in the form of two frames, of which the second frame forms a coil flange with a terminal block which projects beyond the coil axis and in which two pins for the Winding wire ends are attached. In this construction, the relay core element results in a length that extends beyond the length of the actual bobbin when the length of the coil axis from coil flange to coil flange is taken into consideration.

Aus DE 84 28 722 U1 ist ein Spulenkörper mit einer Erregerwicklung zwischen umlaufenden Stirnflanschen bekannt, wobei an einem Stirnflansch ein Kunststoffbügel mit scharnierartigem Gelenk einstückig angespritzt und am anderen Stirnflansch nach Umklappen verrastbar ist. Bei dieser Konstruktion darf die Spule keine große Baulänge aufweisen. Der Kunststoffbügel weist Passöffnungen mit darin eingesteckten Anschlussstifte auf, die mit Wicklungsenden der Spule verlötbar sind. Nach Umklappen des Bügels ragen die Anschlussstifte mit ihren Enden über den Umfang der Spule hinaus, ohne jedoch die Länge der Spule zu beeinträchtigen.Out DE 84 28 722 U1 is a bobbin with a field winding between peripheral end flanges known, wherein at a front flange a plastic strap integrally molded with hinged joint and latched on the other end flange after folding. In this construction, the coil may not have a great length. The plastic bracket has fitting openings with connector pins inserted therein, which can be soldered to coil ends of the coil. After folding the clip, the terminal pins project beyond the circumference of the coil with their ends, but without affecting the length of the coil.

Die US 4,912,438 , US 5,153 543 und US 6,670,871 B1 zeigen polarisierte Relais mit einer Spulenanordnung, mit einem Wippanker und mit einem Basisgehäuse. Die Spulenanordnung umfasst einen magnetischen Kern, einen Spulenkörper, eine gewickelte Spule und einen Permanentmagneten. Das Basisgehäuse stellt einen oben offenen Kunststoffkasten dar, der an seinen Frontseiten stationäre Kontaktanschlüsse sowie Spulenanschlüsse und an seinen Seitenflächen Anschlussstifte aufweist. Der Wippanker ist oberhalb von Spulenanordnung und Basisgehäuse auf dem Permanentmagneten gelagert und trägt die beweglichen Kontaktanschlüsse der Relaisschalter. Wegen der seitlichen Anordnung der Anschlussstifte ist eine schmale Bauweise des Relais nicht möglich.The US 4,912,438 . US 5,153,543 and US Pat. No. 6,670,871 B1 show polarized relay with a coil assembly, with a rocker armature and with a base housing. The coil assembly includes a magnetic core, a bobbin, a wound coil and a permanent magnet. The base housing is an open-topped plastic box having stationary contact terminals and coil terminals on its front sides and pins on its side surfaces. The rocker armature is mounted above the coil assembly and base housing on the permanent magnet and carries the movable contact terminals of the relay switch. Because of the lateral arrangement of the pins, a narrow construction of the relay is not possible.

Die EP 1 246 214 A2 zeigt einen Elektromagnetaufbau mit einem Elektromagneten und einem Anker, der durch den Elektromagneten angetrieben wird, wobei der Elektromagnet eine Spule mit einer Spulenmittelachse umfasst, die auf einen isolierenden Spulenkörper gewickelt ist. Der Spulenkörper bildet einen Hohlkörper vorgegebener Länge, an dessen gegenüberliegenden Längsenden ein Paar ringförmiger Flansche angeordnet sind, wobei an symmetrischen Positionen am Rand eines der Flansche Endstützpunkte angeordnet sind, welche sich von dort in Längsrichtung des Hohlkörpers erstrecken, und wobei an den Endstützpunkten ein Paar Spulenanschlusselemente angeordnet sind, die jeweils mit gegenüberliegenden Drahtenden der Spule des Elektromagneten verbunden sind.The EP 1 246 214 A2 shows an electromagnet assembly with an electromagnet and an armature, which is driven by the electromagnet, wherein the electromagnet comprises a coil having a coil center axis, which is wound on an insulating bobbin. The bobbin forms a hollow body of predetermined length, at its opposite longitudinal ends a pair of annular flanges are arranged, being arranged at symmetrical positions on the edge of one of the flanges Endstützpunkte extending from there in the longitudinal direction of the hollow body, and wherein at the Endstützpunkten a pair of coil connection elements are arranged, which are each connected to opposite wire ends of the coil of the electromagnet.

Kurzbeschreibung der ErfindungBrief description of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Spulenbaugruppe mit Spule, isolierendem Spulenkörper und Anschlussblock zu schaffen, deren Baulänge, in Spulenachsrichtung gemessen, die Baulänge der Spule nicht wesentlich übersteigt, d. h. gegenüber dem Relaiskernelement der EP 2 187 418 A2 verkürzt ist. Dabei darf die Spule eine große Baulänge aufweisen. Ferner soll der Bauraum an der Spulenbaugruppe äußerst ausgenutzt werden können. Insbesondere soll die Spulenbaugruppe für ein solches Relais geeignet sein, dessen Anschlussstifte im radialen Außenbereich der Spule ansetzen.The invention has for its object to provide a coil assembly with coil, insulating bobbin and terminal block whose overall length, measured in Spulenachsrichtung, the overall length of the coil does not significantly exceed that of the Relay core element of EP 2 187 418 A2 is shortened. The coil may have a large overall length. Furthermore, the space on the coil assembly should be extremely exploited. In particular, the coil assembly should be suitable for such a relay, attach the pins in the radial outer region of the coil.

Gemäß Erfindung wird ein Verfahren zur Herstellung einer Spulenbaugruppe vorgeschlagen, die zum Einbau in ein Relais geeignet ist und einen isolierenden Spulenkörper als Wickelträger, eine Spule sowie Anschlussstifte zur elektrischen Verbindung mit der Spule aufweist. Es wird der isolierende, eine Spulenachse aufweisende Spulenkörper mit einem solchen Anschluss-Spulenflansch bereitgestellt, an dem ein Anschlussblock schwenkbar befestigt ist. Der Anschlussblock, der die Anschlussstifte teilweise in einem isolierenden Blockkörper eingebettet aufnimmt, wird in Vorbereitungsstellung verbracht, in welchen er sich in den Raum außerhalb des zum Bewickeln benötigten Spulenaußenraumes erstreckt. Alsdann wird der Spulenkörper mit dem Wickeldraht bewickelt und die Wickeldrahtenden werden nahe des Anschlussspulenflansches aus der Spule herausgeführt und mit den zugehörigen Anschlussstiften verbunden. Danach werden die Anschlussstifte umgebogen. Als nächster Schritt erfolgt das Umbiegen des Anschlussblockes um einen Verformungsabschnitt gegenüber dem Spulenkörper. Dies führt auch zur Zugentlastung des Wickeldrahtes. Es kann so eine Spulenbaugruppe erzielt werden, bei der die Anschlussstifte gewissermaßen aus dem Spulen-Wickelraum und nicht aus einem Verlängerungsraum zur Spulenachse wegstreben oder sich in Ebenen seitlich von der Spule erstrecken. Im Verhältnis zu der Spulenlänge wird eine besonders kurz gebaute Spulenbaugruppe erzielt. Die Spulenbaugruppe kann getrennt von einer Polbaugruppe gehandhabt werden, bei der ein unmagnetisierter, ferromagnetischer Körper die zur Erzielung eines gepolten Relais aufmagnetisiert werden soll.According to the invention, a method for producing a coil assembly is proposed, which is suitable for installation in a relay and having an insulating bobbin as a coil carrier, a coil and connecting pins for electrical connection to the coil. The insulating bobbin having a bobbin axis is provided with such a bobbin flange to which a terminal block is pivotally mounted. The terminal block, which partially accommodates the terminal pins embedded in an insulating block body, is set to a preparation position in which it extends into the space outside the coil outer space required for winding. Then, the bobbin is wound with the winding wire and the winding wire ends are led out of the coil near the Anschlußsspulenflansches and connected to the associated pins. Then the pins are bent. The next step is the bending of the terminal block to a deformation section relative to the bobbin. This also leads to the strain relief of the winding wire. It can thus be achieved a coil assembly in which the pins to a certain extent away from the coil winding space and not from an extension space to the coil axis or extending in planes laterally from the coil. In relation to the coil length is a achieved especially short built coil assembly. The coil assembly can be handled separately from a pole assembly in which an unmagnetized, ferromagnetic body is to be magnetized to achieve a polarized relay.

Die erfindungsgemäße Spulenbaugruppe kann in verschiedenen Varianten verwirklicht werden. Bei vielen Bauarten wird ein fest an den Anschlussspulenflansch angebrachter Ansatz mit einem flexibel-verformbaren Verbindungsbereich zum Anschlussblock benutzt, der aus seiner Vorbereitungsstellung in seine Endstellung verschwenkt wird.The coil assembly according to the invention can be realized in various variants. In many designs, a fixedly attached to the Anschlußsspulenflansch approach is used with a flexible-deformable connection area to the terminal block, which is pivoted from its preparation position to its end position.

In einer ersten Ausführungsform ist der Ansatz mit dem Anschlussblock über einen flexibel-verformbaren Gelenkabschnitt einstückig verbunden.In a first embodiment, the approach to the terminal block via a flexible-deformable hinge portion is integrally connected.

Bei anderen Ausführungsformen gibt es eine metallische Biegezone an einem metallischen Element, das einen der Anschlussstifte oder aber einen gesonderten Biegearm darstellen kann. Die Verbindung des Anschlussblockes mit dem am Anschlussspulenflansch angebrachten Ansatz kann auch über ein Torsionselement erfolgen.In other embodiments, there is a metallic bending zone on a metallic element that may be one of the terminal pins or a separate bending arm. The connection of the terminal block with the attached to the Anschlußsspulenflansch approach can also be done via a torsion.

The terminal block 3 comprises an insulating block body 30 and a flexible-deformable hinge portion 31 in extension of the peripheral edge 11a. The bobbin 1 with flange neck 13, joint portion 31 and block body 30 are made of electrically insulating material, which is suitable for encapsulating of metallic parts. Such metallic parts constitute the terminal pins 35, 36 which are partially embedded in the block body 30 and protrude from the block body 30 with their ends 35a, 36a.

Fig. 1 zeigt den Spulenkörper 1 mit Anschlussblock 13 in der Vorbereitungsstellung vor Bewickeln des Spulenkörpers. Wie ersichtlich, ist das Spulenrohr 10 zwischen den Flanschen 11 und 12 von der Seite behinderungsfrei zugänglich, d. h. der Anschlussblock 3 befindet sich außerhalb des Umrisses des Anschluss-Spulenflansches 11 und außerhalb des zum Bewickeln benötigten Spulen-Wickelraumes. In dieser Stellung des Anschlussblockes 3 wird der Spulenkörper 1 bewickelt, wodurch die Spule 2 (Fig. 2) entsteht, die zwei nicht dargestellte Wickeldrahtenden aufweist, welche im Bereich des Flansches 11 aus der Spule herausgeführt sind und die mit den Anschlussstiften 35 und 36 zum Beispiel durch Löten verbunden werden. Danach werden die nach oben ragenden Enden 35a und 36a der Anschlussstifte 35, 36 umgebogen, um in eine Ebene parallel zur Spulenachse 10a zu gelangen. Alsdann wird der Gelenkabschnitt 31 des Anschlussblockes 3, der sich mit seinen Anschlussstiften 35 und 36 in einer Hauptebene quer zur Spulenachse 10a (Fig. 1) befindet, um eine Achse etwa in Verlängerung der Randkante 11a gebogen, sodass sich der Blockkörper 30 im Großen und Ganzen parallel zur Spulenachse 10a erstreckt, wie dies in Fig. 2 dargestellt ist. Fig. 1 shows the bobbin 1 with terminal block 13 in the preparation position before winding the bobbin. As can be seen, the coil tube 10 is accessible without hindrance between the flanges 11 and 12 from the side, ie, the terminal block 3 is located outside the outline of the connecting coil flange 11 and outside the winding winding space required for winding. In this position of the terminal block 3, the bobbin 1 is wound, whereby the coil 2 (FIG. Fig. 2 ), the two winding wire ends, not shown which are led out of the coil in the region of the flange 11 and which are connected to the connection pins 35 and 36, for example by soldering. Thereafter, the upwardly projecting ends 35a and 36a of the terminal pins 35, 36 are bent to enter a plane parallel to the coil axis 10a. Then, the hinge portion 31 of the terminal block 3, with its connecting pins 35 and 36 in a main plane transverse to the coil axis 10 a ( Fig. 1 ) is bent about an axis approximately in extension of the peripheral edge 11a, so that the block body 30 generally extends parallel to the coil axis 10a, as shown in FIG Fig. 2 is shown.

Die neue Spulenbaugruppe zeichnet sich durch eine kurze Baulänge aus. Dabei sind die Anschlussstifte 35, 36 im Bauraum unmittelbar unterhalb der Spule 2 angeordnet, d. h. die Breite der Flansche 11, 12 deckt die Anschlussstifte 35, 36 ab. Die Spulenbaugruppe ist deshalb zum Einbau sowohl in kleine oder schmal gebaute Relais als auch in Relais mit langem Spulenkörper 1 bestens geeignet.The new coil assembly is characterized by a short overall length. The pins 35, 36 are arranged in the space immediately below the coil 2, d. H. the width of the flanges 11, 12 covers the connection pins 35, 36. The coil assembly is therefore ideally suited for installation in both small or narrow relays as well as relays with a long bobbin 1.

Mit Fig. 3 und 4 wird eine weitere Ausführungsform der neuen Spulenbaugruppe beschrieben. Gleichartige Teile tragen die gleichen Bezugszeichen wie bei der Ausführungsform nach Fig. 1 und 2. Der hauptsächlichste Unterschied besteht in der Verbindung zwischen Flanschansatz 13 und Blockkörper 30. Hierzu wird nämlich ein gekröpfter Anschlussstift 35 benutzt, der am oberen Ende 35a abgebogen ist und einen abgewinkelten Abschnitt 35b aufweist, der in dem Flanschansatz 13 verankert ist. Der Anschlussstift 35 weist noch zwischen den Abschnitten 35a und 35b eine Biegezone 35c auf, die in etwa in Verlängerung der Randkante 11a liegt. Auch der Anschlusstift 36 ist gekröpft, wie aus dem hervorstehenden Ende 36a ersichtlich. Die Spule 2 wird in schon beschriebener Weise auf den Spulenkörper 1 gewickelt, während sich der Anschlussblock 30 in seiner Vorbereitungsstellung gemäß Fig. 3 befindet. Danach werden die Wickeldrahtenden 21 und 22 an die Anschlussstiftenden 35a und 36a angelötet oder sonstwie verbunden. Alsdann wird der Anschlussstift 35 um seine Biegezone 35c gebogen, sodass der Anschlussblock 3 die in Fig. 4 dargestellte Endstellung einnimmt, in welcher die Hauptebene des Anschlussblockes 30 parallel zur Spulenachse 10a verläuft.With Fig. 3 and 4 another embodiment of the new coil assembly will be described. Similar parts bear the same reference numerals as in the embodiment Fig. 1 and 2 , The main difference is in the connection between the flange projection 13 and block body 30. For this purpose, namely a cranked pin 35 is used, which is bent at the upper end 35 a and having an angled portion 35 b, which is anchored in the Flanschansatz 13. The connecting pin 35 still has between the sections 35a and 35b, a bending zone 35c, which lies approximately in extension of the peripheral edge 11a. Also, the terminal pin 36 is cranked, as seen from the protruding end 36a. The coil 2 is wound in the manner already described on the bobbin 1, while the terminal block 30 in its preparation position according to Fig. 3 located. Thereafter, the winding wire ends 21 and 22 are soldered or otherwise connected to the terminal pin ends 35a and 36a. Then, the terminal pin 35 is bent around its bending zone 35c, so that the terminal block 3, the in Fig. 4 shown end position occupies, in which the main plane of the terminal block 30 is parallel to the coil axis 10a.

Fig. 5 und 6 zeigen eine dritte Ausführungsform der Erfindung. Es werden sich entsprechende Teile mit den gleichen Bezugszeichen versehen. Das charakteristische Merkmal der dritten Ausführungsform ist ein Biegearm 37, dessen erster Schenkel 37a im Blockkörper 30 verankert ist, während der zweite Schenkel 37b im Flanschansatz 13 verankert ist. Der Biegearm 37 kann ein abgewinkeltes Teil gemäß den Abschnitten 35a, 35b und 35c des Anschlussstiftes 35 darstellen, der noch ein abgekröpftes Gabelende 35a besitzen kann. Der Spulenkörper 1 wird bewickelt und die Drahtenden 21, 22 werden mit den freien Enden 35a und 36a der Anschlussstifte 35, 36 elektrisch leitend verbunden. Wie zuvor beschrieben wird der Anschlussblock 3 aus der in Fig. 5 dargestellten Vorbereitungsstellung in die Endstellung gemäß Fig. 6 geschwenkt, wobei die Biegzone 37c des Biegearms 37 bleibend verformt wird. Fig. 5 and 6 show a third embodiment of the invention. There will be corresponding parts provided with the same reference numerals. The characteristic feature of the third embodiment is a bending arm 37, whose first leg 37a is anchored in the block body 30, while the second leg 37b is anchored in the flange projection 13. The bending arm 37 may constitute an angled part according to the portions 35a, 35b and 35c of the connecting pin 35, which may still have a bent fork end 35a. The bobbin 1 is wound and the wire ends 21, 22 are electrically conductively connected to the free ends 35a and 36a of the connecting pins 35, 36. As described above, the terminal block 3 is made of the in Fig. 5 Prepared position shown in the end position according to Fig. 6 pivoted, wherein the bending zone 37c of the bending arm 37 is permanently deformed.

Fig. 7 und 8 zeigen eine vierte Ausführungsform der Erfindung. Es werden die gleichen Bezugszahlen wie zuvor benutzt. Der Ansatz 13 am Anschlussspulenflansch 11 weist einen nach unten reichenden Fortsatz 13a auf, um einen Torsionsschenkel 38a eines knieförmigen Verbindungselementes 38 aufzunehmen. Der abgewinkelte Schenkel des Verbindungselementes 38 reicht in den Blockkörper 30 hinein und ist dort verankert. In der Vorbereitungsstellung gemäß Fig. 7 erstreckt sich die Hauptebene des Anschlussblockes 3 quer zur Spulenachse 10a und in dieser Vorbereitungsstellung wird die Spule 2 bewickelt, wonach die Wickeldrahtenden 21, 22 an ihre zugehörigen Anschlussstifte 35, 36 angelötet oder sonstwie leitend befestigt werden. Danach wird der Anschlussblock 3 aus der Stellung der Fig. 7 in die Stellung nach Fig. 8 geschwenkt, wobei der Torsionsschenkel 38a des knieförmigen Verbindungselementes 38 tordiert wird und eine bleibende Verformung erfährt. Fig. 7 and 8th show a fourth embodiment of the invention. The same reference numbers are used as before. The projection 13 on the Anschlußsspulenflansch 11 has a downwardly extending projection 13 a to receive a torsion leg 38 a of a knee-shaped connecting element 38. The angled leg of the connecting element 38 extends into the block body 30 and is anchored there. In the preparation position according to Fig. 7 the main plane of the terminal block 3 extends transversely to the coil axis 10a and in this preparation position the coil 2 is wound, after which the winding wire ends 21, 22 are soldered or otherwise conductively attached to their associated terminal pins 35, 36. Thereafter, the terminal block 3 from the position of Fig. 7 in the position Fig. 8 pivoted, wherein the torsion leg 38a of the knee-shaped connecting element 38 is twisted and undergoes a permanent deformation.
