Description

Die Erfindung geht aus von einem Kontaktierungsstecker nach der Gattung des Anspruchs 1.The invention relates to a Kontaktierungsstecker according to the preamble of claim 1.

Steuergeräte im Automotive-Bereich bestehen meist aus einer Leiterplatte, auf der elektronische Bauelemente platziert sind, und einem Gehäuse. In Motorsteuergeräten wird auf die Leiterplatte üblicherweise eine Messerleiste montiert, um die elektrische Verbindung zwischen einem Kabelbaumstecker und der Leiterplatte herzustellen. Die Messerleiste stellt somit ein zusätzliches Bauteil bei der Montage des Steuergerätes dar.Control devices in the automotive sector usually consist of a printed circuit board, on which electronic components are placed, and a housing. In motor control devices, a male connector is usually mounted on the circuit board to make the electrical connection between a harness connector and the circuit board. The male connector thus represents an additional component in the assembly of the control unit.

Es sind auch so genannte elektrische Direktkontaktierungen bekannt, bei denen die Messerleiste entfällt und die einzelnen Pole des Kabelbaumes direkt auf der Leiterplatte kontaktiert werden. Dazu sind auf der Leiterplatte elektrische Kontaktflächen ("Lands") vorgesehen, die direkt durch Kontaktelemente des Kabelbaumsteckers kontaktiert werden.There are also known as direct electrical contacts, in which the male connector is omitted and the individual poles of the wiring harness are contacted directly on the circuit board. For this purpose, electrical contact surfaces ("lands") are provided on the circuit board, which are contacted directly by contact elements of the harness connector.

Bei der aus der DE 10 2005 063 239 A1 bekannten Direktkontaktierung weist der Kontaktierungsstecker zwei gelenkig miteinander verbundene Kontaktträger auf, die durch eine entgegen der Steckrichtung des Kontaktierungssteckers offene V- bzw. U-förmige Feder in Richtung aufeinander zu vorgespannt sind. Bei ineinander gesteckten Kontaktierungs- und Gegenkontaktierungssteckern befindet sich die Feder vollständig im abgedichteten Bereich des Kontaktierungssteckers, wodurch ihre Federlänge minimiert ist und damit ihre elastischen Federeigenschaften reduziert sind.At the time of the DE 10 2005 063 239 A1 known direct contact, the Kontaktierungsstecker two hingedly interconnected contact carrier, which are biased by an opposite to the plugging direction of the Kontaktierungssteckers open V- or U-shaped spring toward each other. In nested Kontaktierungs- and Gegenkontaktierungssteckern the spring is completely in the sealed area of the Kontaktierungssteckers, whereby their spring length is minimized and thus their elastic spring properties are reduced.

Die Aufgabe der Erfindung besteht demgegenüber darin, bei einem Kontaktierungsstecker der eingangs genannten Art die elastischen Federeigenschaften der Feder zu verbessern, ohne dabei den abgedichteten Bereich des Kontaktierungssteckers zu vergrößern.The object of the invention is in contrast to improve the elastic spring properties of the spring in a Kontaktierungsstecker of the type mentioned, without increasing the sealed portion of the Kontaktierungssteckers.

Vorteile der ErfindungAdvantages of the invention

Diese Aufgabe wird erfindungsgemäß durch einen Kontaktierungsstecker mit den Merkmalen von Anspruch 1 gelöst.This object is achieved by a Kontaktierungsstecker with the features of claim 1.

Erfindungsgemäß ist die Feder mit ihrem Mittelabschnitt im ungedichteten Bereich angeordnet und erstreckt sich mit ihren beiden freien Federschenkeln durch die Dichtung hindurch in den abgedichteten Bereich der Kontaktierungssteckverbindung. Die Feder ist in ihrer Länge also nicht mehr durch die Dichtung begrenzt, sondern erhält zusätzliche Federlänge, ohne den kleinstmöglichen abgedichteten Gesamtbauraum zu beeinflussen. Die Feder (Federkennlinie) kann optimiert werden, erhält so einen größeren Arbeitsbereich und arbeitet im abgedichteten sowie im ungedichteten Bereich des Kontaktierungssteckers. Die Feder ist vorzugsweise eine Bügel- oder Schenkelfeder.According to the invention, the spring is arranged with its central portion in the un-sealed area and extends with its two free spring legs through the seal into the sealed area of the Kontaktierungssteckverbindung. The spring is therefore no longer limited in length by the seal, but receives additional spring length, without affecting the smallest possible sealed overall space. The spring (spring characteristic) can be optimized, so receives a larger work area and works in the sealed and un-sealed area of the Kontaktierungssteckers. The spring is preferably an ironing or thigh spring.

Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further advantages and advantageous embodiments of the subject invention are the description, the drawings and claims removed.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Der in Fig. 1 gezeigte Kontaktierungsstecker (z.B. Kabelbaumstecker) 1 dient zur elektrischen Direktkontaktierung von beidseitig auf einer Leiterplatte 2 vorgesehenen Kontaktflächen ("Lands") 3 (Fig. 2c). Die Steckrichtung des Kontaktierungssteckers 1 ist mit 4 bezeichnet.The in Fig. 1 shown Kontaktierungsstecker (eg harness connector) 1 is used for direct electrical contacting of both sides on a printed circuit board 2 provided contact surfaces ("Lands") 3 ( Fig. 2c ). The plug-in direction of the Kontaktierungssteckers 1 is denoted by 4 .

Der mit der Leiterplatte 2 steckverbindbare Kontaktierungsstecker 1 umfasst zwei, z.B. durch ein Filmscharnier 5 miteinander gelenkig verbundene Kontaktträger 6, die zwischen sich eine Steckaufnahme 7 (Fig. 2b) für die Leiterplatte 2 ausbilden und jeweils eine Reihe von in die Steckaufnahme 7 hineinragenden federnden Kontaktelementen 8 aufweisen, eine entgegen der Steckrichtung 4 offene V- bzw. U-förmige Feder (z.B. Bügel- oder Schenkelfeder) 9, die die beiden Kontaktträger 6 in Richtung aufeinander zu vorspannt, sowie einen zwischen den beiden Kontaktträgern 6 und seitlich neben der Steckaufnahme 7 ausgebildeten Steuerkanal 10, der im Zusammenwirken mit einem an der Leiterplatte 2 vorgesehenen Steuerkeil 11 (Fig. 2a) die beiden Kontaktträger 6 beim Einstecken der Leiterplatte 2 gegen die Wirkung der Feder 9 auf- und durch die Wirkung der Feder 9 zuschwenkt.The plug-in with the circuit board 2 Kontaktierungsstecker 1 includes two, for example, by a film hinge 5 hinged together contact carrier 6, which is a plug-in receptacle 7 (FIG. Fig. 2b ) form for the circuit board 2 and each have a number of projecting into the receptacle 7 resilient contact elements 8 , an opposite to the insertion direction 4 open V- or U-shaped spring (eg bow or leg spring) 9, the two contact carrier 6 in Direction towards one another, as well as a formed between the two contact carriers 6 and laterally next to the plug-in receptacle 7 control channel 10, in cooperation with a provided on the circuit board 2 control wedge 11th ( Fig. 2a ) the two contact carrier 6 on insertion of the circuit board 2 up against the action of the spring 9 and zuschwenkt by the action of the spring 9.

Der Steuerkanal 10 ist durch zwei einander gegenüber liegende Steuervorsprünge 12 der beiden Kontaktträger 6 verengt. Eine Dichtung 13 dichtet den Kontaktierungsstecker 1 in einer Steckbuchse 14 eines Kontaktierungsgegensteckers 15 nach außen ab.The control channel 10 is narrowed by two mutually opposite control projections 12 of the two contact carrier 6. A seal 13 seals the Kontaktierungsstecker 1 in a socket 14 of a Kontaktierungsgegensteckers 15 to the outside.

Fig. 2 zeigt eine bekannte Kontaktierungssteckverbindung 20 zwischen dem Kontaktierungsstecker 1 und dem Kontaktierungsgegenstecker 15. Fign. 2a , 2b zeigt die Kontaktierungssteckverbindung 20 mit teilweise ineinander gesteckten Steckern 1, 14. Der Steuerkeil 11 befindet sich im Steuerkanal 10, aber wirkt noch nicht mit den Steuervorsprüngen 12 zusammen. Die Leiterplatte 2 befindet sich zwischen den beiden Kontaktträgern 6, aber wirkt noch nicht mit den Kontaktelementen 8 zusammen.
Beim weiteren Ineinanderstecken läuft der Steuerkeil 11 auf die beiden Steuervorsprünge 12 auf, wodurch die beiden Kontaktträger 6 gegen die Wirkung der Feder 9 gegeneinander aufgespreizt werden und die Kontaktelemente 8 bezüglich der Leiterplatte 2 angehoben werden ( Fig. 2c ). Wenn beim weiteren Ineinanderstecken der Steuerkeil 11 dann an den Steuervorsprüngen 12 vorbeigeschoben ist, schwenken aufgrund der Feder 9 die beiden Kontaktträger 6 wieder zurück. Dadurch werden die Kontaktelemente 8 auf die Kontaktflächen 3 der Leiterplatte 2 abgesenkt und kontaktieren diese in der Endsteckposition ( Fig. 2d ). Fig. 2 shows a known Kontaktierungssteckverbindung 20 between the Kontaktierungsstecker 1 and the Kontaktierungsgegenstecker 15th FIGS. 2a . 2 B shows the Kontaktierungssteckverbindung 20 with partially nested plugs 1, 14. The control wedge 11 is located in the control channel 10, but does not yet cooperate with the control projections 12. The printed circuit board 2 is located between the two contact carriers 6, but does not yet interact with the contact elements 8.
Upon further nesting the control wedge 11 runs on the two control projections 12, whereby the two contact carrier 6 against the action of the spring 9 are spread apart and the contact elements 8 are raised with respect to the circuit board 2 ( Fig. 2c ). If, in the further nesting of the control wedge 11 is then pushed past the control projections 12, pivot due to the spring 9, the two contact carrier 6 back again. As a result, the contact elements 8 are lowered onto the contact surfaces 3 of the printed circuit board 2 and contact them in the end plug position ( FIG. Fig. 2d ).

Fig. 3 zeigt einen weiteren Kontaktierungsstecker 30 in seiner Endsteckposition im Kontaktierungsgegenstecker 15. Vom Kontaktierungsstecker 1 der Fign. 1 und 2 unterscheidet sich dieser Kontaktierungsstecker 30 lediglich dadurch, dass hier die Feder 9 rund ausgebildet und in Steckrichtung 4 offen ist und mit ihren beiden freien Federschenkeln 9a die beiden Kontaktträger 6 in Steckrichtung 4 übergreift. Die beiden Kontaktträger 6 samt der Feder 9 sind in der Steckbuchse 14 des Kontaktierungsgegensteckers 15 durch die Dichtung 13 rückseitig abgedichtet. Aufgrund des vorgegeben abgedichteten Bauraums ist die Federlänge auf ein Minimum gekürzt, wodurch die Feder 9 fast keine elastische Federwirkung aufweist und daher sehr steif ist. Fig. 3 shows a further Kontaktierungsstecker 30 in its Endsteckposition in Kontaktierungsgegenstecker 15. From the Kontaktierungsstecker 1 of FIGS. 1 and 2 This Kontaktierungsstecker 30 differs only in that here the spring 9 is formed round and open in the insertion direction 4 and with its two free spring legs 9a, the two contact carrier 6 engages over in the insertion direction 4. The two contact carrier 6 together with the spring 9 are sealed in the socket 14 of the Kontaktierungsgegensteckers 15 by the seal 13 back. Due to the predetermined sealed installation space the spring length is reduced to a minimum, whereby the spring 9 has almost no elastic spring action and therefore is very stiff.

Vom Kontaktierungsstecker 30 der Fig. 3 unterscheidet sich der in Fig. 4 gezeigte Kontaktierungsstecker 40 lediglich dadurch, dass hier die Feder 9 U-förmig ausgebildet ist und sich mit ihren beiden Federschenkeln 9a abgedichtet durch die Dichtung 13 hindurch erstreckt, während der mittlere Federabschnitt 9b außerhalb des abgedichteten Bauraums des Kontaktierungssteckers 40 angeordnet ist. Mit anderen Worten befindet sich die Dichtung 13 zwischen den Kontaktträgern 6 und dem mittleren Federabschnitt 9b. Anders als in Fig. 3 ist die Federlänge der Feder 9 nicht länger durch den von der Dichtung 13 vorgegebenen abgedichteten Bauraum des Kontaktierungssteckers begrenzt, sondern die Feder 9 erhält zusätzliche Federlänge und damit höhere elastische Federkraft, ohne den abgedichteten Bauraum zu vergrößern.From Kontaktierungsstecker 30 of Fig. 3 is different in the Fig. 4 contacting plug 40 shown only in that here the spring 9 is U-shaped and with its two spring legs 9a sealed by the seal 13 extends, while the central spring portion 9b is disposed outside of the sealed installation space of the contacting 40th In other words, the seal 13 is between the contact carriers 6 and the central spring portion 9b. Unlike in Fig. 3 the spring length of the spring 9 is no longer limited by the sealed space of the Kontaktierungssteckers predetermined by the seal 13, but the spring 9 receives additional spring length and thus higher elastic spring force, without increasing the sealed space.
