Description

Die vorliegende Erfindung betrifft ein Verfahren gemäss Oberbegriff des Anspruchs 1. Ein solches Verfahren ist bekannt aus DE-GM-79 22 314, wobei in Leiteranschlussgehäusen gehaltene Anschlussstifte mit der Leiterplatte verlötet und dann Klemmenblöcke auf die Leiteranschlussgehäuse aufgeschnappt werden. Die Herstellung ist aufwendig, schwer automatisierbar, auf die angeschlossenen Leiter wirkende Kräfte werden voll auf die Lötverbindungen übertragen, und die Klemmblöcke liegen einseitig der Leiterplatte, so dass nicht besonders raumsparend und kompakt gebaut werden kann.The present invention relates to a method according to the preamble of claim 1. Such a method is known from DE-GM-79 22 314, in which connection pins held in conductor connection housings are soldered to the printed circuit board and terminal blocks are then snapped onto the conductor connection housing. The production is complex, difficult to automate, forces acting on the connected conductors are fully transferred to the soldered connections, and the terminal blocks are located on one side of the circuit board, so that it cannot be built in a particularly space-saving and compact manner.

Aus FR-A-2 532 811 ist es zwar bekannt, Klemmenblöcke mit Anschlussstiften mit der Leiterplatte zu verlöten und die Klemmenblöcke beim Einbau in ein Gehäuse durch einen Gehäuseteil zusätzlich zu sichern. Diese Lösung ist jedoch mit denselben Nachteilen verbunden wie diejenige nach DE-GM-79 22 314.From FR-A-2 532 811 it is known to solder terminal blocks with connecting pins to the printed circuit board and to additionally secure the terminal blocks when installed in a housing by means of a housing part. However, this solution has the same disadvantages as that according to DE-GM-79 22 314.

Ziel vorliegender Erfindung ist es, ein vereinfachtes, gut automatisierbares Herstellungsverfahren anzugeben, das auch zu einer guten Raumnutzung bzw. kompakten Bauweise führt. Dieses Ziel wird gemäss den Ansprüchen 1 bzw. 5 erreicht. Vorzugsweise werden dabei die Klemmblöcke parallel zur Ebene der Leiterplatte seitlich gegen deren Kante lose aufgeschoben und dann beim Einbau in das Gehäuse gesichert. Dabei liegen die Klemmenblöcke vorzugsweise asymmetrisch zur Leiterplatte und stehen einseitig etwa entspreched der Höhe der Lötstellen und auf der anderen Seite etwa entsprechend der Höhe der Komponenten über die Leiterplatte vor, was eine optimale Raumnutzung bzw. kompakte, flache Bauweise ermöglicht.The aim of the present invention is to provide a simplified, easily automatable manufacturing process which also leads to good use of space or compact design. This goal is achieved according to claims 1 and 5, respectively. Preferably, the terminal blocks are loosely pushed laterally parallel to the plane of the circuit board against its edge and then secured during installation in the housing. The terminal blocks are preferably asymmetrical to the circuit board and are on one side approximately corresponding to the height of the solder joints and on the other hand approximately according to the height of the components above the circuit board, which enables optimal use of space or compact, flat design.

Das Gehäuse des dargestellten Gerätes weist einen schalenartigen Unterteil 1 mit einem Boden und Seitenwänden auf, mit welchem ein Deckel 2 mittels federnder Haken 3 verbunden werden kann. Eine Stirnabdeckung 4 kann auf die Stirnwand 5 aufgeschnappt werden, und dort Durchbrechungen 6 dieser Stirnwand teilweise abdecken. In das Gehäuse des Gerätes wird eine Leiterplatte 7 eingesetzt, die in der Zeichnung schematisch ohne Leiterbahnen aber mit einigen darauf angeordneten Schaltelementen dargestellt ist (Fig. 3). Die Leiterbahnen befinden sich an der in Fig. 1 sichtbaren Oberseite der Leiterplatte 7. Sie ist am Rande mit Ausschnitten 8 versehen, welche den Durchtritt der Haken 3 erlauben. In Fig. 1 sind Kupplungselemente 9 dargestellt, welche mit einstellbaren Schaltelementen, beispielsweise Potentiometern, der Leiterplatte 7 verbunden werden können und welche durch Oeffnungen der Stirnabdeckung 4 betätigt werden können. Das Gerät weist im übrigen Klemmenblöcke 10 auf, welche in noch zu beschreibender Weise mit der Leiterplatte 7 elektrisch verbunden und im Gehäuse gesichert sein können. In Halteblöcken angeordnete Anschlussfahnen zur Verbindung der Leiterplatte 7 mit den Klemmenblöcken 10 liegen in Fig. 1 an der Unterseite der Leiterplatte und sind nicht sichtbar, wohl aber in Fig. 3, und ihre Einzelheiten sind in den Fig. 4 und 5 gezeigt. Diese Halteblöcke 11 aus Kunststoff weisen Nuten 12 und Durchbrechungen 13 auf, in welche symmetrisch angeordnete gezahnte Haltelappen 14 mit aus dem Halteblock 11 beidseitig vorragenden Lötfahnen 15 von geriffelten Anschlussfahnen 16 eingesteckt sind. Die Verbindungsstücke 17 zwischen den Haltelappen 14 und den Anschlussfahnen 16 sind so gestaltet, dass die drei Anschlussfahnen 16 in einer gemeinsamen Ebene liegen. Wie Fig. 3 zeigt, steht diese Ebene bei montierten Anschlussfahnen 16 senkrecht zur Ebene der Leiterplatte 7. Die Halteblöcke 11 sind mit seitlichen Haken 18 versehen, welche durch Löcher 19 der Leiterplatte 7 durchgreifen und damit die Halteblöcke 11 auf der Leiterplatte sichern können. Diese Sicherung dient einem noch zu erläuternden Zweck bei der Montage des Gerätes.The housing of the device shown has a shell-like lower part 1 with a bottom and side walls, with which a cover 2 can be connected by means of resilient hooks 3. An end cover 4 can be snapped onto the end wall 5 and there partially cover openings 6 of this end wall. A circuit board 7 is inserted into the housing of the device, which is shown schematically in the drawing without conductor tracks but with some switching elements arranged thereon (FIG. 3). The conductor tracks are located on the upper side of the printed circuit board 7 visible in FIG. 1. It is provided with cutouts 8 on the edge, which allow the hooks 3 to pass through. 1 shows coupling elements 9 which can be connected to the circuit board 7 with adjustable switching elements, for example potentiometers, and which can be actuated by openings in the front cover 4. The device points in remaining terminal blocks 10, which can be electrically connected to the circuit board 7 in a manner to be described and secured in the housing. Terminal lugs arranged in holding blocks for connecting the printed circuit board 7 to the terminal blocks 10 lie on the underside of the printed circuit board in FIG. 1 and are not visible, but are visible in FIG. 3, and their details are shown in FIGS. 4 and 5. These holding blocks 11 made of plastic have grooves 12 and openings 13, into which symmetrically arranged toothed holding tabs 14 with soldering tabs 15 of corrugated connecting tabs 16 projecting from the holding block 11 on both sides are inserted. The connecting pieces 17 between the holding tabs 14 and the connecting lugs 16 are designed such that the three connecting lugs 16 lie in a common plane. As shown in FIG. 3, this level is perpendicular to the plane of the printed circuit board 7 when the connecting lugs 16 are mounted. The holding blocks 11 are provided with lateral hooks 18 which pass through holes 19 in the printed circuit board 7 and can thus secure the holding blocks 11 on the printed circuit board. This fuse serves a purpose to be explained when installing the device.

Fig. 2 zeigt einen Klemmenblock 10 im Längsschnitt. Jeder Klemmenblock 10 weist drei Halterungen für je eine Kastenklemme 20 auf, die mittels einer Schraube 21 verschoben werden kann. In das Fenster 22 jeder Kastenklemme ragt einerseits eine Anschlussfahne 16 und andererseits das abisolierte Ende 23 eines Anschlussleiters 24 hinein. Mittels der Schraube 21 kann die Kastenklemme 20 aus der dargestellten Lage nach oben verschoben werden, so dass dann der Draht 23 fest gegen die Anschlussfahne 16 geklemmt wird, womit eine zuverlässige elektrische und mechanische Verbindung dieser Teile erstellt ist. Der Klemmenblock weist einen die mittlere Anschlussfahne 16 aufnehmenden Kragen 26 (Fig. 2 und 3) auf, welcher in montiertem Zustand (Fig. 3, links) in eine Nut 27 des Halteblockes 11 eingreift und damit zur Verlängerung der Kriechwege zwischen den drei Anschlussfahnen beiträgt. Die Klemmenblöcke sind einseitig mit einem Haken 28 versehen, welcher bei montiertem Gerät hinter eine Rippe 29 des Gehäuses greift während die andere Seite des Klemmenblockes in eine Haltetasche 30 der Gehäusewand greift. Damit ist der Klemmenblock auch im Gehäuse allseitig gesichert, wenn der Deckel 2 aufgesetzt ist. Der weiteren Sicherung und Führung beim Aufstecken des Klemmenblockes auf die Anschlussfahnen 16 bzw. gegen die Leiterplatte (7) dienen Paare von Führungsfahnen 32.Fig. 2 shows a terminal block 10 in longitudinal section. Each terminal block 10 has three brackets for a box terminal 20, which can be moved by means of a screw 21. In the window 22 of each box terminal, a connection lug 16 projects on the one hand and the stripped end 23 of a connection conductor 24 on the other. By means of the screw 21, the box clamp 20 can be shifted upward from the position shown, so that the wire 23 is then firmly clamped against the connecting lug 16, which creates a reliable electrical and mechanical connection of these parts. The terminal block has a collar 26 (FIGS. 2 and 3) which receives the central connecting lug 16 and which in FIG assembled state (Fig. 3, left) engages in a groove 27 of the holding block 11 and thus contributes to the extension of the creepage distances between the three connecting lugs. The terminal blocks are provided on one side with a hook 28 which, when the device is mounted, engages behind a rib 29 of the housing while the other side of the terminal block engages in a holding pocket 30 in the housing wall. The terminal block is thus secured on all sides in the housing when the cover 2 is placed on. Pairs of guide tabs 32 serve for further securing and guiding when the terminal block is plugged onto the connecting tabs 16 or against the printed circuit board (7).

Wie eingangs erwähnt, gestattet die erfindungsgemässe Konzeption eine besonders rationelle Montage des Gerätes. Die Klemmenblöcke und die mit Anschlussfahnen 16 bestückten Halteblöcke 11 werden gemäss Fig. 2 bzw. 4 und 5 vorbereitet. Dann wird die Leiterplatte 7 in üblicher Weise mit Komponenten bestückt, wobei auch die zwei Halteblöcke 11 mit Anschlussfahnen 16 wie die übrigen Komponenten auf die Leiterplatte aufgesetzt und mittels der Haken 18 auf derselben gesichert werden. Dabei greifen die einen Lötfahnen 15 durch vorbereitete Löcher 31 der Leiterplatte durch. Sodann wird die Leiterplatte im Wellenbad gelötet, wobei die Lötfahnen 15 der Anschlussfahnen 16 mit Leiterbahnen verlötet werden, wie die übrigen Komponenten der Leiterplatte.As mentioned at the outset, the concept according to the invention permits particularly efficient installation of the device. The terminal blocks and the holding blocks 11 equipped with terminal lugs 16 are prepared according to FIGS. 2, 4 and 5. Then the circuit board 7 is fitted with components in the usual way, the two holding blocks 11 with terminal lugs 16 being placed on the circuit board like the other components and secured on the circuit board by means of the hooks 18. One of the solder lugs 15 reaches through prepared holes 31 in the printed circuit board. The circuit board is then soldered in the wave pool, the soldering lugs 15 of the connection lugs 16 being soldered to conductor tracks, like the other components of the circuit board.

Die Leiterplatte ist nun gemäss Fig. 3 mit den beiden Halteblöcken mit Anschlussfahnen 16 und den übrigen Komponenten fertiggestellt. Es werden nun die beiden Klemmenblöcke 10 auf die Anschlussfahnen 16 lose aufgeschoben, wie in Fig. 3 links dargestellt, wobei der Kragen 26 mit seinem sich nach aussen erweiternden Durchgang die Lage des Klemmenblockes beim Aufstecken bestimmt und damit die Montage erleichtert.3 with the two holding blocks with connecting lugs 16 and the other components. The two terminal blocks 10 are now loosely pushed onto the connecting lugs 16, as shown on the left in FIG. 3, the collar 26, with its passage widening outwards, determining the position of the terminal block when plugged on and thus facilitating assembly.

Sind die beiden Klemmenblöcke 10 in dieser Weise lose an die Leiterplatte angesteckt, werden sie zusammen mit derselben in den Unterteil 1 des Gehäuses eingesetzt, wobei nun auch die Klemmenblöcke durch das Gehäuse definitiv in ihrer Lage gesichert werden. Dann werden gegebenenfalls die Kupplungselemente 9 eingesetzt und die Stirnabdeckung 4 aufgesetzt, und schliesslich wird der Deckel 2 aufgesteckt, womit das Gerät fertig montiert ist. Diese Montage eignet sich besonders für eine Automation.If the two terminal blocks 10 are loosely attached to the circuit board in this way, they are inserted together with the latter into the lower part 1 of the housing, the terminal blocks now also being definitely secured in their position by the housing. Then, if necessary, the coupling elements 9 are inserted and the front cover 4 is put on, and finally the cover 2 is put on, with which the device is fully assembled. This assembly is particularly suitable for automation.

Bevor allerdings der Deckel aufgesetzt wird, kann eine endgültige Prüfung auf Spannungsfestigkeit und Funktion des Gerätes erfolgen, in dem nämlich die Leiterplatte mit oben liegenden Lötstellen in den Gehäuseunterteil 1 eingesetzt wird und somit alle Lötstellen zugänglich sind. Die Prüfung auf Spannungsfertigkeit kann über die Anschlussklemmen bzw. über die Anschlussfahnen erfolgen.Before the cover is put on, however, a final test can be carried out to determine the dielectric strength and function of the device, namely by inserting the circuit board with the solder joints on top into the lower housing part 1 and thus all solder joints are accessible. The test for voltage capability can be carried out via the connection terminals or the connection lugs.

In den Fig. 6 und 7 ist eine Ausführungsvariante schematisch dargestellt. Die Leiterplatte 7 ist in diesem Falle mit einem Halteblock 11' bestückt, dessen Anschlussfahnen 16' in einer gemeinsamen Ebene liegen, die parallel zur Ebene der Leiterplatte liegt. Ein passend ausgebildeter Klemmenblock 10' kann auf die Anschlussfahnen aufgesteckt und mit denselben verbunden werden. In Fig. 7 ist angedeutet, dass mehr als drei Anschlussfahnen vorgesehen sein können. Es können natürlich auch weniger Anschlussfahnen vorgesehen sein, oder es könnte nur ein Klemmenblock und ein Satz von Anschlussfahnen vorgesehen sein.An embodiment variant is shown schematically in FIGS. 6 and 7. The printed circuit board 7 is in this case equipped with a holding block 11 ', the connecting lugs 16' of which lie in a common plane which is parallel to the plane of the printed circuit board. A suitably designed terminal block 10 'can be plugged onto the connection lugs and connected to the same. In Fig. 7 it is indicated that more than three connection lugs can be provided. Of course, fewer connection lugs can be provided, or only one terminal block and a set of connection lugs could be provided.

In Fig. 8 ist eine Variante 10' des Klemmblocks dargestellt, wobei entsprechende Teile gleich bezeichnet sind wie in Fig. 2. Der wesentliche Unterschied besteht darin, dass jeder Kastenklemme 20 ein U-förmiger Bügel 25 zugeordnet ist, welcher den unteren Teil der Kastenklemme umgreift. In der dargestellten offenen Lage ist der untere Schenkel des Bügels 25 zwischen der Kastenklemme und einem Boden 20a gehalten, so dass der obere Schenkel des Bügels etwa mitten im Fenster 22 liegt. Es können nun über und unter diesem Schenkel abisolierte Drähte 23a bzw. 23b unterschiedlichen Durchmessers eingeführt und durch Festziehen der Klemme sicher geklemmt werden. Der Klemmenblock ist im übrigen mit zwei Haken 28 bzw. 28a für eine etwas andere Halterung im Gehäuse versehen.FIG. 8 shows a variant 10 'of the terminal block, the corresponding parts being identified in the same way as in FIG. 2. The main difference is that each box terminal 20 has a U-shaped bracket 25 is assigned, which encompasses the lower part of the box clamp. In the open position shown, the lower leg of the bracket 25 is held between the box clamp and a bottom 20a, so that the upper leg of the bracket lies approximately in the middle of the window 22. Stripped wires 23a and 23b of different diameters can now be inserted above and below this leg and securely clamped by tightening the clamp. The terminal block is also provided with two hooks 28 and 28a for a slightly different holder in the housing.

Da die Halteblöcke 11 oben und unten Lötfahnen 15 aufweisen, könnten sie mit je zwei übereinanderliegenden Leiterplatten 7 verlötet sein. Die Lötfahnen können auch mit dem Kunststoff der Halteblöcke umspritzt sein, womit eine bessere Spannungsfestigkeit erzielt werden kann.Since the holding blocks 11 have solder tabs 15 at the top and bottom, they could be soldered to two printed circuit boards 7 one above the other. The solder tabs can also be extrusion-coated with the plastic of the holding blocks, with which a better dielectric strength can be achieved.
