Description

Vorrichtung zur Befestigung einer Diode in einem Tastengehäuse unter gleichzeitigem elektrischem Anschluß der Diode an Anschlußorgane, die im Tastengehäuse verankert und aus diesem herausgeführt sind, bei der die Diode beidseits eines Diodenkörpers in einer gemeinsamen Achse aus dem Diodenkörper herausragende Anschlußdrahtabschnitte aufweist, und mit im Tastengehäuse vorgesehenen, einseitig offenen Aufnahmeschlitzen, in welchen die Anschlußdrahtabschnitte der Diode durch die Einwirkung eines Tastengehäuseteils auf den Diodenkörper festgehalten sind.Device for fastening a diode in a button housing with simultaneous electrical connection of the diode to connection members which are anchored in and led out of the button housing, in which the diode has connecting wire sections protruding from the diode body on both sides of a diode body, and provided in the button housing , one-sided open receiving slots in which the lead wire sections of the diode are held by the action of a key housing part on the diode body.

Eine solche Vorrichtung ist aus der E-PS 28 000 bekannt. Bei der bekannten Vorrichtung werden die Aufnahmeschlitze auf beiden Seiten durch Tastengehäusewandabschnitte begrenzt. Die durch die Einwirkung eines Tastengehäuseteils auf den Diodenkörper in den Aufnahmeschlitzen festgehaltenen Anschlußdrahtabschnitte der Diode werden gegen am Grund der Aufnahmeschlitze vorgesehene Kontaktflächen der Anschlußorgane gedrückt.Such a device is known from E-PS 28 000. In the known device, the receiving slots are delimited on both sides by key housing wall sections. The connecting wire sections of the diode, which are held in the receiving slots by the action of a button housing part on the diode body, are pressed against contact surfaces of the connecting members provided at the bottom of the receiving slots.

Auf diese Weise kann eine für jede einzelne Taste benötigte Sperrdiode unkompliziert in das Tastengehäuse eingelegt und dabei zugleich elektrisch an Anschlußorgane angeschlossen werden, die aus dem Tastengehäuse herausgeführt sind, ohne daß hierzu Lötarbeiten erforderlich sind.In this way, a blocking diode required for each individual key can be easily inserted into the key housing and at the same time electrically connected to connection elements which are led out of the key housing, without the need for soldering work.

Aufgabe vorliegender Erfindung ist es, eine Vorrichtung der eingangs genannten Art wo weiterzubilden, daß unter Aufrechterhaltung der unkomplizierten Montagemöglichkeit der Diode die Kontaktgabe zwischen den Anschlußdrahtabschnitten der Diode und den Anschlußorganen des Tastengehäuses noch verbessert wird.The object of the present invention is to develop a device of the type mentioned where that under Maintaining the uncomplicated mounting possibility of the diode, the contact between the connecting wire sections of the diode and the connecting elements of the button housing is still improved.

Erfindungsgemäß ergibt sich die Lösung dieser Aufgabe dadurch, daß die Aufnahmeschlitze seitlich einerseits lediglich durch jeweils eines der stiftförmigen Anschlußorgane und andererseits jeweils durch einen Tastengehäusewandabschnitt begrenzt sind.According to the invention this object is achieved in that the receiving slots are laterally limited on the one hand only by one of the pin-shaped connecting members and on the other hand each by a button housing wall section.

Auf diese Weise wird vorteilhaft einerseits der Aufbau des Tastengehäuses vereinfacht, andererseits eine mehr einem Schleifkontakt ähnliche Kontaktgabe zwischen den Anschlußdrahtabschnitten der Diode und den Anschlußorganen erzielt, wodurch die Kontaktsicherheit zwischen diesen Teilen noch weiter erhöht wird.In this way, on the one hand, the structure of the button housing is advantageously simplified, on the other hand, a contact similar to that of a sliding contact between the connecting wire sections of the diode and the connecting members is achieved, as a result of which the contact reliability between these parts is increased still further.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß der Abstand der frei von einem Gehäuseteil des Tastengehäuses abstehenden Anschlußorgane von den Tastengehäusewandabschnitten geringer bemessen ist, als der Durchmesser der Anschlußdrahtabschnitte und daß die Tastengebäusewandabschnitte am offenen Ende der Auf- nahmeschlitze, im Bereich des freien Endes der Anschlußorgane, mit einer die Aufnahmeschlitze erweiternden Abschrägung versehen sind.In a further embodiment of the invention, it can be provided that the distance of the connection elements which project freely from a housing part of the key housing from the key housing wall sections is smaller than the diameter of the connecting wire sections and that the key housing wall sections at the open end of the receiving slots, in the region of the free end of the connecting members are provided with a bevel which widens the receiving slots.

Dadurch wird erreicht, daß die Anschlußdrahtabschnitte der Diode die stiftförmigen Anschlußorgane geringfügig von den Tastengehäusewandabschnitten wegdrücken müssen, wenn die Anschlußdrahtabschnitte in die Aufnahmeschlitze eingedrückt werden. Durch die Federwirkung der stiftförmigen Anschlußorgane werden die Anschlußdrahtabschnitte der Diode zwischen den Anschlußorganen und den GehäusewandabschnittenIt is thereby achieved that the connecting wire sections of the diode have to push the pin-shaped connecting members slightly away from the key housing wall sections when the connecting wire sections are pressed into the receiving slots. Due to the spring action of the pin-shaped connecting members, the connecting wire sections of the diode between the connecting members and the housing wall sections

eingeklemmt und ein sicherer elektrischer Kontakt zwischen den Anschlußdrahtabschnitten und den Anschlußorganen hergestellt, der u.a. durch den zueinander rechtwinkligen Verlauf jeweils eines Anschlußdrahtabschnittes und eines Anschlußorganes gewährleistet wird.clamped and a secure electrical contact between the lead wire sections and the connecting elements is established, which, among other things. is guaranteed by the mutually perpendicular course of a connecting wire section and a connecting element.

Schließlich kann im Rahmen vorliegender Erfindung noch vorgesehen sein, daß die Tiefe der Aufnahmeschlitze durch Tastengehäusequerwände begrenzt ist.Finally, it can be provided in the context of the present invention that the depth of the receiving slots is limited by key housing transverse walls.

Dadurch wird ein Widerlager zu dem auf den Diodenkörper einwirkenden Tastengehäuseteil gebildet, so daß durch die geringfügige Federwirkung der Anschlußdrahtabschnitte der Diode der Diodenkörper federnd gegen das auf ihn einwirkende Tastengehäuseteil gedrückt gehalten wird.As a result, an abutment to the button housing part acting on the diode body is formed, so that the diode body is pressed resiliently against the button housing part acting on it due to the slight spring action of the connecting wire sections of the diode.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von zwei Figuren noch näher erläutert.An embodiment of the invention is explained in more detail below with reference to two figures.

Dabei zeigen, jeweils im Schnitt und stark vergrößert,

  • Fig. 1 eine Drucktaste in Seitenansicht und
  • Fig. 2 eine Ansicht von oben auf den Teil der in Fig. 1 dargestellten Taste, in welchem die Sperrdiode im Tastengehäuse gehalten wird, mit nicht dargestelltem Tastengehäusedeckel.
Show, each in section and greatly enlarged,
  • Fig. 1 is a push button in side view
  • Fig. 2 is a top view of the part of the key shown in Fig. 1, in which the blocking diode is held in the key housing, with the key housing cover, not shown.

Im einzelnen ist den Figuren zu entnehmen, daß die Taste ein Tastengehäuse besitzt, das im wesentlichen aus einem Gehäuseunterteil 1 und einem mit diesem verrastbaren Gehäuseoberteil 2 besteht. Auf einer Seite der Tastenbetätigungseinrichtung 3 sind im Gehäuseunterteil 1 zwei Kammern 4 vorgesehen, die jeweils durch die Außenwand 5 des Unterteils und zwei an der Außenwand 5 ansetzende Wandabschnitte 6 des Unterteils 1 begrenzt werden. Auf den einander zugewandten Selten 7 sind die Kammern 4 offen und begrenzen zwischen sich eine Ausnehmung 8, die zur Aufnahme des Körpers 9 einer Sperrdiode 10 ausgebildet ist. Aus den kreisförmigen Stirnflächen 11 des Körpers 9 der Sperrdiode 10 stehen in der Achse des Diodenkörpers 9 Anschlußdrahtabschnitte 12 vor.In detail, it can be seen from the figures that the key has a key housing, which essentially consists of a lower housing part 1 and an upper housing part 2 which can be locked with this. On one side of the key actuation device 3, two chambers 4 are provided in the lower housing part 1, each of which is delimited by the outer wall 5 of the lower part and two wall sections 6 of the lower part 1 attached to the outer wall 5. On the mutually facing rare 7, the chambers 4 are open and delimit between them a recess 8 which is designed to receive the body 9 of a blocking diode 10. From the circular end faces 11 of the body 9 of the blocking diode 10, 9 connecting wire sections 12 protrude in the axis of the diode body.

In jede Kammer 4 ragt ein stiftförmiges Anschlußorgan 13, das im Boden 14 des Unterteils 1 verankert Ist und diesen durchdringt. Jedes der beiden Anschlußorgane 13 bildet zusammen mit einem wandabschnitt 6 einen Aufnahmeschlitz 15, in den einer der Anschlußdrahtabschnitte 12 der Sperrdiode 10 quer zum Verlauf des jeweiligen Anschlußorganes 13 eingedrückt werden kann. Der Abstand zwischen einem Anschlußorgan 13 und einem wandabschnitt 6 im Bereich einer Kammer 4 ist so gewählt, daß ein Anschlußdrahtabschnitt 12 nur unter federnder Auslenkung des freien Endes 16 eines Anschlußorganes in den Aufnahmeschlitz 15 gedrückt werden kann.A pin-shaped connecting element 13 projects into each chamber 4 and is anchored in the bottom 14 of the lower part 1 and penetrates it. Each of the two connecting members 13 forms, together with a wall section 6, a receiving slot 15 into which one of the connecting wire sections 12 of the blocking diode 10 can be pressed transversely to the course of the respective connecting member 13. The distance between a connecting member 13 and a wall section 6 in the region of a chamber 4 is selected such that a connecting wire section 12 can only be pressed into the receiving slot 15 with the free deflection of the free end 16 of a connecting member.

Um das Eindrücken eines Anschlußdrahtabschnittes 12 in den Aufnahmeschlitz 15 zu erleichtern, Ist jeder Wandabschnitt 6 mit einer Abschrägung 17 versehen. Die Abschrägung 17 reicht dabei bis in den Bereich des freien Endes 16 eines Anschlußorganes 13, so daß die Diode 10 mit Ihren Anschlußdrahtabschnitten 12 zunächst kräftefrei zwischen das freie Ende 16 der Anschlußorgane 13 und die Abschrägungen 17 der beiden Wandteile 6 eingelegt werden kann.In order to facilitate the pressing in of a connecting wire section 12 into the receiving slot 15, each wall section 6 is provided with a bevel 17. The bevel 17 extends into the area of the free end 16 of a connecting element 13, so that the diode 10 with its connecting wire sections 12 can initially be inserted without force between the free end 16 of the connecting elements 13 and the bevels 17 of the two wall parts 6.

Die beiden Anschlußdrahtabschnitte 12 werden schließlich in den beiden Aufnahmeschlitzen 15 dadurch festgehalten, daß ein Deckel 18 des Gehäuseoberteiles 2 bei der Verrastung von Unterteil 1 und Oberteil 2 des Tastengehäuses sich gegen den Körper 9 der Diode 10 legt und dadurch verhindert, daß die Anschlußdrahtabschnitte 12 wieder aus den Aufnahmeschlitzen 15 herausgleiten können.The two connecting wire sections 12 are finally held in the two receiving slots 15 in that a cover 18 of the upper housing part 2 when the lower part 1 and upper part 2 of the button housing lock against the body 9 of the diode 10 and thereby prevents the connecting wire sections 12 again can slide out of the receiving slots 15.

Im Bereich der beiden Kammern 4 sind zum Boden 14 parallele Querwände 19 vorgesehen . Diese Querwände 19 begrenzen die für die Anschlußdrahtabschnitte 12 wirksame Tiefe der Schlitze 15. Durch eine entsprechend gewählte Höhe dieser Querwände 19, bezüglich der Endlage des Diodenkörpers 10 im Tastengehäuse, kann erreicht werden, daß unter Ausnutzung einer bestimmten Elastizität der Anschlußdrahtabschnitte 12 der Diodenkörper 9 federnd gegen den Deckel 18 des Oberteiles 2 des Tastengehäuses gedrückt gehalten wird.In the region of the two chambers 4, transverse walls 19 parallel to the floor 14 are provided. These transverse walls 19 limit the effective depth of the slots 15 for the connecting wire sections 12. By a correspondingly selected height of these transverse walls 19, with respect to the end position of the diode body 10 in the button housing, it can be achieved that, using a certain elasticity of the connecting wire sections 12, the diode body 9 is resilient is pressed against the lid 18 of the upper part 2 of the button housing.

Durch die auf diese Weise gebildeten Kreuzkontakte zwischen jeweils einem Anschlußdrahtabschnitt 12 und einem Anschlußorgan 13 wird eine betriebssichere und dauerhafte Kontaktgabe zwischen den Anschlußorganen 13 und der Diode 10 sichergestellt. Diese Kontaktgabe kann noch durch entsprechende Oberflächenbeschichtungen zumindest der Anschlußorgane 13, zum Beispiel durch eine Verzinnung, verbessert werden.The cross contacts formed in this way between a respective connecting wire section 12 and a connecting element 13 ensure reliable and permanent contact between the connecting elements 13 and the diode 10. This contacting can be improved by appropriate surface coatings of at least the connection elements 13, for example by tinning.
