Das in Fig. 1 im Längsschnitt dargestellte Gehäuse 1 ist quaderförmig aufgebaut und besteht aus einem isolierenden Kunststoff. An seiner einen Seite enthält es eine Einstecköffnung 2, die den Zugang zu dem Innenraum 3 des Gehäuses ermöglicht. In dem Gehäuse 1, genauer gesagt in dessen Innenraum 3, ist ein Klemmelement 4 untergebracht, das zum Einstecken eines Messers durch die Einstecköffnung 2 bestimmt und ausgebildet ist. Auf der der Einstecköffnung 2 gegenüberliegenden Seite des Gehäuses 1 ragt aus diesem ein Ansatz 5 heraus, der einen Teil des Klemmelements 4 bildet bzw. mit diesem einstückig verbunden ist. Der Ansatz 5 des Klemmelements 4 weist einen viereckigen Querschnitt auf und ist so dimensioniert, daß er in eine durchkontaktierte Bohrung einer Leiterplatte eingepreßt werden kann. Bei diesem Einpressen, in Fig. 1 also von rechts nach links, gelangt am Ende des Einpreßvorgangs die rückwärtige Fläche 6 des Gehäuses 1 zur flächigen Anlage an der Seite der Leiterplatte, so daß durch dieses Einpressen auch das Gehäuse 1 an der Leiterplatte angebracht wird.The housing 1 shown in longitudinal section in FIG. 1 is cuboid and consists of an insulating Plastic. It has an insertion opening on one side 2, which gives access to the interior 3 of the housing allows. In the housing 1, more precisely in its Interior 3, a clamping element 4 is housed, which for Inserting a knife determined through the insertion opening 2 and is trained. On the insertion opening 2 opposite One side of the housing 1 protrudes from this out, which forms part of the clamping element 4 or with this is integrally connected. The approach 5 of the clamping element 4 has a quadrangular cross section and is so dimensioned so that it is in a plated-through hole Printed circuit board can be pressed. With this press-in, 1 from right to left, arrives at the end of the Pressing the rear surface 6 of the housing 1 to flat system on the side of the circuit board, so that by this pressing also the housing 1 on the circuit board is attached.

Das Klemmelement 4 kann durch die Einstecköffnung 2 in den Innenraum 3 des Gehäuses 1 eingeschoben werden. Diese Einstecköffnung 2 ist in Fig. 2 noch deutlicher zu sehen. Fig. 2 zeigt eine Ansicht des Gehäuses 1 der Fig. 1 von rechts. Die Einstecköffnung enthält einen mittleren nach oben gerichteten Bereich, der von einer Seitenwand 7 des Gehäuses begrenzt wird. Das Klemmelement 4 ist innerhalb der Einstecköffnung 2 vollständig zu sehen. Daraus ergibt sich, daß es auch durch diese Einstecköffnung 2 eingeschoben werden kann.The clamping element 4 can through the insertion opening 2 in the Interior 3 of the housing 1 are inserted. This insertion opening 2 can be seen even more clearly in FIG. FIG. 2 shows a view of the housing 1 of FIG. 1 from the right. The insertion opening contains a middle upward Area by a side wall 7 of the housing is limited. The clamping element 4 is inside the insertion opening 2 fully seen. It follows that can also be inserted through this insertion opening 2.

Fig. 3 und 4 zeigen das Klemmelement 4 von der Seite und von oben. Das Klemmelement 4 ist als einstückiges Stanzteil aus Blech ausgebildet. Es enthält zwei flache in einer gemeinsamen Ebene liegende Arme 8, zwischen denen durch je einen Schlitz 9 getrennt eine Zunge 10 angeordnet ist. Die Zunge 10 ist an einem die beiden Arme verbindenden Steg 11 mit diesem verbunden. Die Zunge 10 ist so gebogen, daß sie in ihrem unmittelbar an den Steg 11 angrenzenden Bereich aus der Ebene der Arme 8 nach oben abgebogen ist und anschließend sich in einer geraden Linie der Oberseite der Arme 8 wieder nähert. In geradliniger Verlängerung der Arme 8 sind jenseits des Stegs 11 zwei Ansätze 5 zum Einpressen in die Leiterplatte angeformt, die auf diese Weise einen gewissen Abstand voneinander aufweisen. Dadurch verbessert sich die mechanische Verbindung zwischen dem Klemmelement und der Leiterplatte.3 and 4 show the clamping element 4 from the side and from above. The clamping element 4 is made as a one-piece stamped part Sheet metal trained. It contains two flat ones in one Level arms 8, between each by one Slot 9 a tongue 10 is arranged separately. The tongue 10 is on a web 11 connecting the two arms with this connected. The tongue 10 is bent so that it is in her area directly adjacent to the web 11 from the plane the arm 8 is bent upwards and then in a straight line approaches the top of the arms 8 again. In a straight line extension of the arms 8 are beyond Web 11 two approaches 5 for pressing into the circuit board molded in this way a certain distance from each other exhibit. This improves the mechanical Connection between the clamping element and the circuit board.

Die Außenkanten 12 beider Ansätze 5 weisen einen geringeren Abstand voneinander auf als die entsprechenden Außenkanten 13 der beiden Arme 8. Dadurch wird an den rückwärtigen Enden der Arme 8 jeweils eine Schulter 14 gebildet, die die Einschiebebewegung des Klemmelements 4 in den Innenraum 3 des Gehäuses 1 begrenzen kann. Die Schultern 14 liegen an entsprechenden Gehäuseanschlägen an, wie dies im folgenden noch beschrieben werden wird.The outer edges 12 of both approaches 5 have a smaller one Distance from each other than the corresponding outer edges 13 of the two arms 8. This will at the rear ends of the Arms 8 each formed a shoulder 14, which is the insertion movement of the clamping element 4 in the interior 3 of the housing 1 can limit. The shoulders 14 rest on corresponding ones Housing stops as described below will be.

Bei der Darstellung der Fig. 1 ist zu sehen, daß bei eingesetztem Klemmelement 4 die vorderen Enden der Arme 8 und der Zunge 9 einen gewissen Abstand von der Fläche der Einstecköffnung 2 haben. Die Erfindung schlägt jedoch auch vor, daß die freien Enden der Arme 8 und der Zunge 10 bündig mit der Vorderseite des Gehäuses 1 verlaufen.1 it can be seen that when inserted Clamping element 4 the front ends of the arms 8 and Tongue 9 a certain distance from the surface of the insertion opening Have 2. However, the invention also proposes that the free ends of the arms 8 and the tongue 10 flush with the Front of the housing 1 run.

Fig. 5 zeigt eine Stirnansicht eines zweiten Gehäuses 1, das in diesem Falle zwei Einstecköffnungen 2 aufweist. Bei der Darstellung der Fig. 5 sind die Klemmelemente noch nicht eingeschoben. Die Einstecköffnung 2 wird in Fig. 5 unten von einer Innenwand 15 des Gehäuses begrenzt, auf der die Arme 8 vollflächig aufliegen. Beidseits ist in der Einstecköffnung 2 unmittelbar angrenzend an die Innenwand 15 eine Nut 16 zu sehen, deren Breite der Dicke der Arme 8 entspricht. Dadurch kann das Klemmelement so in den Innenraum 3 eingeschoben werden, daß die Arme 8 direkt auf der Wand 15 liegen. Der verbreiterte Teil der Einstecköffnung 2 dient dazu, die Zungen 10 aufzunehmen und ihre Verformung beim Einstecken des Messers zuzulassen.Fig. 5 shows an end view of a second housing 1, the in this case has two insertion openings 2. In the 5, the clamping elements are not yet inserted. The insertion opening 2 is shown in Fig. 5 below an inner wall 15 of the housing on which the arms 8 lie on the full surface. On both sides is 2 a groove 16 immediately adjacent to the inner wall 15 see whose width corresponds to the thickness of the arms 8. Thereby the clamping element can thus be inserted into the interior 3 be that the arms 8 lie directly on the wall 15. The widened part of the insertion opening 2 serves the Record tongues 10 and their deformation when inserting the Allow knife.
