This object is solved by the features of claim 1.
indem die Schneid-Klemm-Vorrichtung außerhalb des Gehäuses angeordnet ist, werden keine Öffnungen im Gehäuse zum Einführen der elektrischen Leiter mehr benötigt, durch welche bisher häufig Außenluft, Feuchtigkeit und sonstige chemische Stoffe eindrangen und auf der Leiterplatte mit ihren elektronischen Bauelementen zu Schäden führten. Die Schneid-Klemm-Vorrichtung ist deshalb mit ihrem Grundkörper an der Oberfläche der Gehäuseaußenseite montiert bzw. in diese eingesetzt oder mit eingespritzt, wobei an dem Grundkörper ein elektrisch-leitfähiger Kontaktstift zur Gehäuseinnenseite durch das Gehäuse hindurch vorgesehen ist. Während somit die Leiter außerhalb des Gehäuses mittels der Schneid-Klemm-Verbindung kontaktiert werden, ist der Kontaktstift im Innern des Gehäuses mit der Leiterplatte verbunden.by arranging the insulation displacement device outside the housing, there are no openings in the housing for inserting the electrical conductors more, which previously used to cause outside air, moisture and other chemical substances penetrate and on the circuit board with their electronic components caused damage. The insulation displacement device is therefore with its body on the surface of the Assembled or inserted into the outside of the housing or injected with it, an electrically conductive contact pin on the base body Housing inside is provided through the housing. While thus the conductors outside the housing by means of the insulation displacement connection to be contacted, is the contact pin inside the housing connected to the circuit board.
Besonders vorteilhaft ist es dabei, daß das Gehäuse aus Kunststoff ist und der Kontaktstift bereits bei der Herstellung des Gehäuses in diesen integriert wird, insbesondere beim Verspritzen der Kunststoffmasse bereits von dieser umschlossen wird.It is particularly advantageous that the housing is made of plastic and the Contact pin is integrated into the housing during manufacture, especially when spraying the plastic mass from this is enclosed.
Gemäß Patentanspruch 3 weist die Leiterplatte in der elektrischen
Anschlußzone eine Öffnung auf. Der Kontaktstift ist mittels einer Presspassung
zwischen Außenfläche des Kontaktstifts und Innenfläche der Öffnung und/oder
durch eine Lötverbindung arretiert und elektrisch leitend verbunden. Durch
eine Presspassung kann auch auf ein Verlöten der Kontaktstifte mit den
Anschlußzonen der Leiterplatte verzichtet werden, wodurch in erheblichem
Umfang Fertigungskosten eingespart werden können.According to
Durch zusätzliche Halteklemmen ohne schneiden wird der isolierte Leiter arretiert ohne die Isolation zu verletzen.The insulated conductor is cut by means of additional holding clamps without cutting locked without damaging the insulation.
Gemäß Patentanspruch 5 ist es besonders vorteilhaft, wenn zum Anschluß von Flachleiterbahnen eine entsprechende Anzahl parallel zueinander angeordnete, untereinander jedoch elektrisch isolierter Schneid-Klemm-Vorrichtungen vorgesehen sind, wobei für alle Leiter der Flachleiterbahn eine über die gesamte Breite der Flachleiterbahn gehende Halte-Klemm-Vorrichtung vorgesehen ist, weiche die Leiter einerseits in die Schneiden drückt und andererseits die Leiter entsprechend arretiert.According to claim 5, it is particularly advantageous if for connecting Flat conductor tracks a corresponding number in parallel to each other arranged, but mutually electrically insulated insulation displacement devices are provided, one for all conductors of the flat conductor track Holding and clamping device extending over the entire width of the flat conductor track is provided, the ladder on the one hand into the cutting edges presses and on the other hand locks the ladder accordingly.
Gemäß Patentanspruch 6 weist das Gehäuse bevorzugt eine Einbuchtung auf,
in der die Schneid-Klemm-Vorrichtungen angeordnet sind und die einen
Anschlag aufweist, an den die Leiter nur derart angelegt werden können, daß
diese dann bezogen auf die jeweils zugeordneten Schneid-Klemm-Vorrichtungen
ausgerichtet sind. Dadurch kann die Montage weitgehend
automatisiert und Fehlbestückungen vermieden werden.According to

Die einzige Figur zeigt ein Gehäuse 1 zur Aufnahme einer Leiterplatte 2 und
eine Schneid-Klemm-Vorrichtung 4 zum elektrischen Verbinden eines isolierten
Leiters 5 mit einer Anschlußzone 3 auf der Leiterplatte. In der Figur wurde eine
Schnittdarstellung gewählt, die eine Schneid-Klemm-Vorrichtung im Detail
zeigt, von der jedoch eine Vielzahl parallel zueinander hintereinander
angeordneter für die Kontaktierung mit einem Flachleiterbahnkabel
vorgesehen sind. Das Gehäuse 1 weist auf der Innenseite die Leiterplatte 2 und
auf der Außenseite 1.2 eine Einbuchtung 13 auf, In welcher die Schneid-Klemm-Vorrichtung
4 angeordnet ist. Die Schneid-Klemm-Vorrichtung 4 besteht in
diesem Ausführungsbeispiel aus zwei Paaren von schneiden 4.2 sowie ebenfalls
zwei Paaren von Halteklemmen 4.1 ohne Schneiden, welche alle zusammen auf
dem Grundkörper 4.3 angeordnet sind. Der Grundkörper 4.3 der Schneid-Klemm-Vorrichtung
4 ist mit seiner Unterseite an der Oberfläche der
Gehäuseaußenseite 1.2 angeordnet. Die Gehäuseaußenseite 1.2 kann dabei im
Bereich des Grundkörpers 4.3 noch zusätzlich eine Aussparung für den
Grundkörper 4.3 aufweisen, so daß dieser in die Gehäuseaußenseite 1.2
abgesenkt werden kann. Auch anderweitige Einsetzmöglichkeiten bis hin zum
Einspritzen auch des Grundkörpers 4.3 ins Kunstoffmaterial sind denkbar.The single figure shows a housing 1 for receiving a
An der Unterseite des Grundkörpers 4.3 ist ein elektrisch leitfähiger Kontaktstift 4.4 zur Gehäuseinnenseite 1.1 durch das Gehäuse 1 hindurch vorgesehen. Der Kontaktstift 4.4 wird dabei vorzugsweise bereits bei der Herstellung des Kunststoffgehäuses mit der Kunststoffmasse eingespritzt. Grundsätzlich ist jedoch ein nachträgliches Einfügen des Kontaktstifts 4.4 in das Gehäuse 1 möglich. Die Dichtheit der Anordnung würde jedoch nachteilig beeinflußt.On the underside of the base body 4.3 is an electrically conductive contact pin 4.4 provided to the inside of the housing 1.1 through the housing 1. The contact pin 4.4 is preferably already in the manufacture of the Plastic housing injected with the plastic compound. Basically is however, a subsequent insertion of the contact pin 4.4 into the housing 1 possible. However, the tightness of the arrangement would be adversely affected.
Über der Einbuchtung 13 ist eine Abdeckung 6 vorgesehen, welche mittels
eines Kunststoffilmscharniers 7 mit dem Gehäuse 1 beweglich verbunden ist
und durch die Einrastmittel 9 und 10 am Gehäuse 1 arretiert wird. Die Einrastmittel
9 und 10 weisen jeweils einen Haken an der Abdeckung 6 und eine
Einraststelle an der Gehäuseaußenseite 1.2 auf. Das Einrastmittel 9 dient
insbesondere zur Entlastung des Kunststoffilmscharniers 7. Außerdem weist
die Abdeckung 6 Stützstege 8 auf, die den Leiter 5 in die Klemmen 4.1 und
schneiden 4.2 eindrücken und danach ein Abgleiten verhindern. Der Leiter 5
besteht aus einem elektrisch leitenden Kern 5.1 und einer Isolation 5.2. Der
Leiter 5 wird bei geöffneter Abdeckung 6 in die Öffnung 11 der Abdeckung 6
eingeführt und dann beim Schließen der Abdeckung 6 in einem Arbeitsgang
gleichzeitig mittels der Stützstege 8 in die Schneiden 4.2 und Klemmen 4.1
eingepreßt. Dabei zertrennen die Schneiden 4.2, wie in der Figur angedeutet,
die Isolation 5.2 des Leiters 5, so daß es zu einer elektrisch leitenden
Verbindung zwischen dem elektrisch leitenden Kern 5.1 des Leiters 5 über die
metallischen Schneiden 4.2, den Grundkörper 4.3 und den Kontaktstift 4.4 der
Schneld-Klemm-Vorrichtung 4 zu der elektrischen Anschlußzone 3 der
Leiterplatte kommt.A
Die symmetrische Anordnung der Schneiden 4.2 und Klemmen 4.1 bezüglich
des Kontaktstifts 4.4 ist mechanisch vorteilhaft, jedoch nicht zwingend
erforderlich. Die Klemmen 4.1 dienen zur zugentlastung des Leiters 5. Durch
die Anordnung der Schneid-Klemm-Vorrichtung 4 an der Außenseite 1.2 des
Gehäuses 1 kann das Gehäuse 1 sehr einfach als wasserdichtes Kunststoffgehäuse
ausgeführt werden und nachträglich noch elektrisch mit den Leitbahnen
verbunden werden, ohne daß betreffend der Dichtheit des Gehäuses
besondere Vorkehrungen zu treffen sind.The symmetrical arrangement of the cutting edges 4.2 and clamps 4.1 with respect
