Description

Die Erfindung bezieht sich auf eine Kontakthülse zum Einsetzen in eine Ausnehmung eines Gehäuse- oder Trägerbauteils eines Meßwerks, die mit den Meßwerk elektrisch leitend verbindbar ist, wobei in die Ausnehmung eine Kontakt- bzw. Befestiungsschraube einschraubbar ist, durch die eine Leiterplatte in Anlage an einen stirnseitigen Mündungsbereich der Ausnehmung anpreßbar ist und wobei ein Leiterbahnbereich der Leiterplatte mit der Kontakthülse elektrisch leitend verbindbar ist.The invention relates to a contact sleeve for insertion into a recess of a housing or support component of a measuring mechanism, which can be electrically conductively connected to the measuring mechanism, wherein a contact or fastening screw can be screwed into the recess, through which a circuit board in contact with one frontal mouth area of the recess can be pressed and a conductor track area of the circuit board can be connected to the contact sleeve in an electrically conductive manner.

Bei einer derartigen Kontakthülse ist es bekannt, mittels der Kontaktschraube eine Kontaktierung eines Leiterbahnbereichs der Leiterplatte mit der Kontakthülse herzustellen. Dabei liegt die Kontaktschraube mit ihren Schraubenkopf auf der dem Gehäusebauteil abgewandten Seite der Leiterplatte auf der Leiterbahn auf.In the case of such a contact sleeve, it is known to use the contact screw to make contact with a conductor track region of the printed circuit board with the contact sleeve. The contact screw rests with its screw head on the side of the circuit board facing away from the housing component on the conductor track.

Aufgabe der Erfindung ist es, eine Kontakthülse der eingangs genannten Art zu schaffen, die eine hohe Kontaktzuverlässigkeit gewährleistet und unverändert für die verschiedensten Anordnungen des Leiterbahnbereichs auf der Leiterplatte verwendbar ist.The object of the invention is to provide a contact sleeve of the type mentioned at the outset, which ensures a high level of contact reliability and can be used unchanged for the most varied arrangements of the conductor track region on the printed circuit board.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kontakthülse an ihrem der Leiterplatte zugewandten Ende eine sich etwa radial nach außen erstreckende flanschartige Erweiterung aufweist, die sich in den stirnseitigen Mündungsbereich der Ausnehmung zwischen Gehäuse- oder Trägerbauteil und darauf anpreßbarer Leiterplatte erstreckt.This object is achieved in that the contact sleeve has at its end facing the circuit board an approximately radially outwardly extending flange-like extension which extends into the front mouth area of the recess between the housing or carrier component and the circuit board which can be pressed thereon.

Diese Ausbildung ermöglicht es, den Leiterbahnbereich zum einen auf der dem Gehäusebauteil abgewandten Seite anzuordnen, wobei die Schraube sowohl als Kontaktschraube als auch als Befestigungsschraube dient.This design makes it possible to arrange the conductor track area on the one hand on the side facing away from the housing component, the screw serving both as a contact screw and as a fastening screw.

In einer anderen Möglichkeit ist der Leiterbahnbereich auf der dem Gehäusebauteil zugewandten Seite angeordnet. In diesen Fall liegt die flanschartige Erweiterung großflächig an dem Leiterbahnbereich an und stellt so den Kontakt sicher her. Die Schraube hat in diesem Fall nur die Funktion zur Befestigung der Leiterplatte an dem Gehäusebauteil und zum Aufpressen des Leiterbahnbereichs auf die flanschartige Erweiterung.In another possibility, the conductor track area is arranged on the side facing the housing component. In this case, the flange-like extension lies over a large area on the conductor track area and thus reliably establishes contact. In this case, the screw only has the function of fastening the circuit board to the housing component and pressing the conductor track area onto the flange-like extension.

Die flanschartige Erweiterung dient aber nicht nur zur Kontaktierung, sondern bildet gleichzeitig einen Montageanschlag beim Einsetzen der Kontakthülse in die Ausnehmung des Gehäusebauteils.The flange-like extension is not only used for contacting, but also forms a mounting stop when inserting the contact sleeve into the recess of the housing component.

Weiterhin wirkt die flanschartige Erweiterung in bestimmten Umfang als Federarm und wird beim Aufschrauben der Schraube zwischen dem Gehäusebauteil und der Leiterplatte verspannt, wodurch sowohl die Kontaktsicherheit erhöht wird als auch Herstellungstoleranzen ausgeglichen werden können.Furthermore, the flange-like extension acts to a certain extent as a spring arm and is clamped between the housing component and the circuit board when the screw is screwed on, as a result of which both the reliability of contact is increased and manufacturing tolerances can be compensated for.

Besonders einfach herstellbar ist die Kontakthülse, wenn die flanschartige Erweiterung durch einen oder mehrere radial nach außen gerichtete Lappen gebildet ist. Dadurch kann die Kontakthülse aus einem zu einer Hülse gebogenen Blechteil bestehen, in dessen Endbereich Lappen bildende axiale Einschnitte vorhanden sind, die ein radial nach außen Umbiegen der Lappen ermöglichen. Diese Ausbildung verbessert auch das Federverhalten und damit die Kontaktsicherheit der Erweiterung.The contact sleeve is particularly simple to manufacture if the flange-like extension is formed by one or more radially outwardly directed tabs. Thereby the contact sleeve can consist of a sheet metal part bent into a sleeve, in the end region of which there are flap-forming axial incisions which enable the flaps to be bent radially outwards. This training also improves the spring behavior and thus the contact security of the extension.

Die Kontaktschraube ist vorzugsweise mit ihrem gegenüber dem Schraubenschaft radial sich erweiternden Schraubenkopf an den auf der dem Gehäuse- oder Trägerbauteil abgewandten Seite der Leiterplatte angeordneten Leiterbahnbereich anpreßbar.The contact screw can preferably be pressed with its screw head, which widens radially with respect to the screw shaft, onto the conductor track region arranged on the side of the printed circuit board facing away from the housing or carrier component.

Zur Erhöhung der Kontaktsicherheit und zum Schutz des Leiterbahnbereichs gegen Abrieb kann zwischen Schraubenkopf und Leiterbahnbereich eine Kontaktlochscheibe angeordnet sein, wobei die Kontaktsicherheit noch erhöht wird, wenn zwischen Schraubenkopf und Kontaktlochscheibe eine Federscheibe anordenbar ist.To increase the contact security and to protect the conductor track area against abrasion, a contact hole disk can be arranged between the screw head and the conductor track area, the contact reliability being increased even further if a spring washer can be arranged between the screw head and the contact hole disk.

Ist die Ausnehmung durchgehend und die Kontakthülse sich durch die gesamte Ausnehmung erstreckend ausgebildet, wobei flanschartige Erweiterungen sich in beide stirnseitigen Mündungsbereiche der Ausnehmung erstrecken, so können die beiden Varianten der Leiterplattenkontaktierungen an jedem Ende der Ausnehmung angewandt werden. Dies führt dazu, daß eine einzige Ausführung einer Kontakthülse für die verschiedensten Anbauvarianten der Leiterplatte verwendet werden können, so daß eine kostengünstige Herstellung und Lagerhaltung der Kontakthülse möglich ist.If the recess is continuous and the contact sleeve extends through the entire recess, with flange-like extensions extending into both front mouth areas of the recess, the two variants of the circuit board contacts can be used at each end of the recess. This means that a single version of a contact sleeve can be used for a wide variety of mounting variants of the printed circuit board, so that the contact sleeve can be manufactured and stored inexpensively.

Erstreckt sich die flanschartige Erweiterung radial nach außen unter einem spitzen Winkel zum stirnseitigen Mündungsbereich des Gehäuse- oder Trägerbauteils, so wird die Federwirkung der flanschartigen Erweiterung und damit die Kontaktsicherheit noch erhöht.If the flange-like extension extends radially outwards at an acute angle to the front mouth area of the housing or carrier component, then the Spring effect of the flange-like extension and thus the contact reliability is increased.

Ausnehmung und Kontakthülse können einen kreisförmigen oder auch einen mehreckigen, insbesondere quadratischen Querschnitt aufweisen. Dabei hat der mehreckige Querschnitt den Vorteil, daß durch ihn gleichzeitig eine formschlüssige Sicherung gegen Verdrehen um die Längsachse der Kontakthülse in der Ausnehmung gegeben ist.The recess and the contact sleeve can have a circular or even a polygonal, in particular square, cross section. The polygonal cross-section has the advantage that it provides positive locking against rotation about the longitudinal axis of the contact sleeve in the recess.

Besitzt die Kontakthülse einen durchgehenden Längsschlitz, kann auf einfache Weise durch das Einschrauben der Kontakt- bzw. Befestigungsschraube ein Spreizen und damit ein lagesicherndes Festpressen der Kontakthülse in der Ausnehmung erreicht werden.If the contact sleeve has a continuous longitudinal slot, spreading and thus securing the position of the contact sleeve in the recess can be achieved in a simple manner by screwing in the contact or fastening screw.

Bei einer Kontakthülse mehreckigen Querschnitts erstreckt sich vorzugsweise der Längsschlitz entlang einer Ecke der Kontakthülse.In the case of a contact sleeve with a polygonal cross section, the longitudinal slot preferably extends along a corner of the contact sleeve.

Zur Einschraubbarkeit der Schraube in die Kontakthülse kann in einer Ausführungsform die Kontakt- bzw. Befestigungsschraube in die Kontakthülse selbstschneidend bzw. gewindefurchend einschraubbar sein. Dies ist besonders gut möglich, wenn die Innenwand der Kontakthülse und/oder die der Leiterbahn zugewandte Fläche des Kontaktflansches mit einer gut leitfähige, leicht plastisch verformbaren Schicht, wie z. B. einer Zinnschicht, versehen ist. Diese Schicht ist vorzugsweise aus einem Werkstoff, der zusätzlich einen niedrigen Übergangswiderstand besitzt und nicht oxidierend ist.To be able to screw the screw into the contact sleeve, in one embodiment the contact or fastening screw can be screwed into the contact sleeve in a self-tapping or thread-tapping manner. This is particularly possible if the inner wall of the contact sleeve and / or the surface of the contact flange facing the conductor track has a highly conductive, easily plastically deformable layer, such as, for. B. a tin layer is provided. This layer is preferably made of a material which additionally has a low contact resistance and is not oxidizing.

Durch die leichte plastische Verformbarkeit wird sowohl im Bereich des Schraubenschafts als auch im Bereich der flanschartigen Erweiterung eine Formanpassung der aneinanderliegenden Teile und damit eine hohe Kontaktsicherheit erreicht.Due to the easy plastic deformability, the shape of the adjoining one is adapted both in the area of the screw shank and in the area of the flange-like extension Parts and thus a high level of contact reliability achieved.

Eine weitere Ausführungsform für die Einschraubbarkeit der Schraube besteht darin, daß an der Innenwand der Kontakthülse zumindest ein radial nach innen gerichteter Vorsprung zum Eingriff in den Gewindegang der Kontakt- bzw. Befestigungsschraube ausgebildet ist. Um die Kontaktsicherheit zu erhalten, sind vorzugsweise mehrere Vorsprünge entsprechend der Steigung des Gewindegangs der Kontakt- bzw. Befestigungsschraube höhen- und seitensetzt ausgebildet.A further embodiment for the screwability of the screw consists in that at least one radially inwardly directed projection for engaging in the thread of the contact or fastening screw is formed on the inner wall of the contact sleeve. In order to maintain the contact reliability, a plurality of projections are preferably formed in accordance with the pitch and pitch of the thread of the contact or fastening screw.

Zur Sicherung der Kontakthülse in der Ausnehmung gegen Verdrehen um die Längsachse und/oder gegen axiales Verschieben kann die Kontakthülse mit Kraft- und/oder Reib- und/oder Formschluß in die Ausnehmung einsetzbar sein. Dazu kann die Kontakthülse an ihrer äußeren Mantelfläche mit einer Aufrauhung versehen sein, die z. B. durch eine Rändelung gebildet ist.To secure the contact sleeve in the recess against rotation about the longitudinal axis and / or against axial displacement, the contact sleeve can be inserted into the recess with force and / or friction and / or positive locking. For this purpose, the contact sleeve can be provided on its outer lateral surface with a roughening which, for. B. is formed by knurling.

Eine andere Möglichkeit besteht darin, daß die Kontakthülse einen von ihrer äußeren Mantelfläche hervorstehenden Vorsprung aufweist.Another possibility is that the contact sleeve has a projection protruding from its outer surface.

Auch kann die Kontakthülse einen von ihrer äußeren Mantelfläche abstehenden federnden Arm aufweisen.The contact sleeve can also have a resilient arm projecting from its outer lateral surface.

Weiterhin kann die Kontaktfläche an ihrer äußeren Mantelfläche eine Öffnung aufweisen, in die ein entsprechender von der Innenwand der Ausnehmung hervorstehender Ansatz eingreifbar ist.Furthermore, the contact surface can have an opening on its outer lateral surface, into which an appropriate extension projecting from the inner wall of the recess can be engaged.

Zum Anschluß des Meßwerkes kann die Kontakthülse eine Kontaktfahne aufweisen. Ist dabei die Kontaktfahne durch Herausbiegen eines teilausgestanzten Wandabschnitts aus der Mantelfläche der Kontakthülse gebildet, so ist für die Kontaktfahne kein zusätzlicher Materialbedarf erforderlich.The contact sleeve can have a contact tab for connecting the measuring mechanism. Is the contact tab by bending a partially punched out wall section from the Formed outer surface of the contact sleeve, no additional material is required for the contact tab.
