Definitions
- Such a device is e.g. made known by DE-C-27 41 791. Then the cable is clamped between the clamp-shaped clamping piece and a flat support part. If you want the individual wires protruding from the cable along the support part e.g. lead to their connection points, this requires a double curvature first to the circuit board and then a counter-curvature up to the parallel course to the circuit board.
- the invention has for its object to let the wires emerge from the cable in the most straight possible way.
- the switching cable is now in its central axis in the plane of the carrier plate, whereby the average exit height of the individual wires and thus their curvature is significantly reduced.
- the veins can almost stretched along the circuit board so that the wave resistance is hardly changed.
- Particularly favorable conditions are achieved if the single wires are distributed on both sides of the carrier plate.
- the use of two clamping pieces makes it possible for the cable to be clamped largely uniformly around its circumference, as a result of which it is only slightly deformed.
- the geometry of the cable, in particular the position of the wires remains largely unchanged, which has an advantageous effect on the impedance.
- the height of the device is also reduced by the thickness of the support plate.
- the carrier plate designed as a printed circuit board can have open shielding or ground layers at the points of contact with the clamping pieces, with which the clamping piece is contacted in large numbers and over a large area and which are connected to one another.
- the cable grommet is held in a simple manner between the two clamping pieces. This is made possible by the fact that the cable grommet is inserted with its ring groove between the two clamping pieces before assembly. The cable grommet is then held in a form-fitting manner between the clamping pieces.
- an electrical assembly serving as a cable connector consists of a printed circuit board 1, cover caps 2, a plug part (not shown) and clamp-like clamping pieces 3 between which the ends of two switching cables 4 are clamped with their exposed cable shield.

Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Anschließen und/oder Festlegen eines elektrischen Kabelschirms bzw. eines elektrischen Schaltkabels an einem plattenförmigen Trägerteil mittels zumindest eines schellenartigen Klemmstückes.The invention relates to a device for connecting and / or fixing an electrical cable shield or an electrical switching cable to a plate-shaped carrier part by means of at least one clamp-like clamping piece.
Eine derartige Einrichtung ist z.B. durch die DE-C-27 41 791 bekannt geworden. Danach wird das Kabel zwischen dem schellenförmigen Klemmstück und einem flachen Trägerteil eingeklemmt. Will man die aus dem Kabel herausragenden einzelnen Adern entlang dem Trägerteil z.B. zu ihren Anschlußstellen führen, so bedingt dies eine Doppelkrümmung zunächst zur Leiterplatte hin und dann eine Gegenkrümmung bis zum parallelen Verlaufe zur Leiterplatte.Such a device is e.g. made known by DE-C-27 41 791. Then the cable is clamped between the clamp-shaped clamping piece and a flat support part. If you want the individual wires protruding from the cable along the support part e.g. lead to their connection points, this requires a double curvature first to the circuit board and then a counter-curvature up to the parallel course to the circuit board.
Z.B. bei hochfrequenz führenden Kabeln mit Koaxialleitern ändern Krümmungen die geometrische Beziehung zwischen dem Signalleiter und dem Leiterschirm, was sich auf den Wellenwiderstand des Leiters ungünstig auswirkt.E.g. in the case of high-frequency cables with coaxial conductors, curvatures change the geometric relationship between the signal conductor and the conductor shield, which has an unfavorable effect on the characteristic impedance of the conductor.
Der Erfindung liegt die Aufgabe zugrunde, die Adern in möglichst gestrecktem Verlauf aus dem Kabel austreten zu lassen.The invention has for its object to let the wires emerge from the cable in the most straight possible way.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst. Das Schaltkabel befindet sich nun in seiner Mittelachse in der Ebene der Trägerplatte, wodurch die durchschnittliche Austrittshöhe der Einzeladern und damit deren Krümmung erheblich verringert wird. Die Adern können nahezu gestreckt entlang der Leiterplatte geführt werden, so daß der Wellenwiaerstand kaum verändert wird. Besonders günstige Verhältnisse werden erreicht, wenn die Einzeladern auf beide Seiten der Trägerplatte verteilt werden. Durch die Verwendung zweier Klemmstücke ist es möglich, daß Kabel an seinem Umfang weitgehend gleichmäßig einzuklemmen, wodurch es nur geringfügig deformiert wird. Dadurch bleibt die Geometrie des Kabels, insbesondere die Lage der Adern weitgehend unverändert, was sich vorteilhaft auf den Wellenwiderstand auswirkt. Die Bauhöhe der Einrichtung verringert sich außerdem um die Dicke der Trägerplatte. Die als Leiterplatte ausgebildete Trägerplatte kann an den Berührungsstellen mit den Klemmstücken offene Schirm- oder Masselagen aufweisen, mit denen das Klemmstück vielfach und großflächig kontaktiert wird und die miteinander verbunden werden.This object is achieved by the invention according to claim 1. The switching cable is now in its central axis in the plane of the carrier plate, whereby the average exit height of the individual wires and thus their curvature is significantly reduced. The veins can almost stretched along the circuit board so that the wave resistance is hardly changed. Particularly favorable conditions are achieved if the single wires are distributed on both sides of the carrier plate. The use of two clamping pieces makes it possible for the cable to be clamped largely uniformly around its circumference, as a result of which it is only slightly deformed. As a result, the geometry of the cable, in particular the position of the wires, remains largely unchanged, which has an advantageous effect on the impedance. The height of the device is also reduced by the thickness of the support plate. The carrier plate designed as a printed circuit board can have open shielding or ground layers at the points of contact with the clamping pieces, with which the clamping piece is contacted in large numbers and over a large area and which are connected to one another.
Durch eine vorteilhafte Weiterbildung der Erfindung nach Anspruch 2 wird die Kabeltülle in einfacher Weise zwischen den beiden Klemmstücken gehalten. Dies wird dadurch ermöglicht, daß die Kabeltülle mit ihrer Ringnut zwischen die beiden Klemmstücke vor dem Montieren eingesetzt wird. Danach ist die Kabeltülle formschlüssig zwischen den Klemmstücken gehalten.Through an advantageous development of the invention according to claim 2, the cable grommet is held in a simple manner between the two clamping pieces. This is made possible by the fact that the cable grommet is inserted with its ring groove between the two clamping pieces before assembly. The cable grommet is then held in a form-fitting manner between the clamping pieces.

Einzelne Adern 5 des Schaltkabels 4 sind vom Kabelende aus entlang der Leiterplatte zu Anschlußstellen 6 der Leiterplatte geführt. Die Klemmstücke 3 befinden sich am rückseitigen Rand der Leiterplatte 1. Diese ist in diesem Bereich mit Durchbrüchen versehen, die in der Art einer Ausklinkung bis zum rückseitigen Leiterplattenrand reichen. Die Schaltkabel 4 ragen in diese Durchbrüche 7 hinein. Die beiden gleichen Klemmstücke 3 überbrücken die Durchbrüche 7 und sind zu beiden Seiten der Leiterplatte 1 angesetzt, und sind mit Massekontaktflächen der Leiterplatte 1 kontaktiert, wobei die Mittelachse des Kabelendes in der Mittelebene der Leiterplatte liegt. Die Adern sind auf beide Seiten der Leiterplatte 1 verteilt und in weitgehend gestrecktem Verlauf zu den Anschlußstellen 6 geführt.According to FIGS. 1 and 2, an electrical assembly serving as a cable connector consists of a printed circuit board 1, cover caps 2, a plug part (not shown) and clamp-like clamping pieces 3 between which the ends of two switching cables 4 are clamped with their exposed cable shield. Individual wires 5 of the switching cable 4 are guided from the cable end along the circuit board to connection points 6 of the circuit board. The clamping pieces 3 are located on the rear edge of the circuit board 1. This is provided with openings in this area, which extend in the manner of a notch to the rear edge of the circuit board. The switching cables 4 protrude into these openings 7. The two same clamping pieces 3 bridge the openings 7 and are attached to both sides of the printed circuit board 1, and are in contact with ground contact surfaces of the printed circuit board 1, the central axis of the cable end lying in the central plane of the printed circuit board. The cores are distributed on both sides of the circuit board 1 and guided to the connection points 6 in a largely elongated course.
Entlang der Rückseite der Leiterplatte 1 sind die Klemmstücke mit rechtwinklig abgebogenen Schenkeln 8 versehen, die sich senkrecht zu den Kabeln 4 erstrecken. Diese Schenkel weisen in entgegensetzter Richtung und sind mit Ausnehmungen 9 zum Einsetzen von Kabeltüllen 10 versehen. Sie bilden zwischen den beiden Abdeckkappen 2 eine Gehäuserückwand des Kabelsteckers.Along the back of the circuit board 1, the clamping pieces are provided with legs 8 bent at right angles, which extend perpendicular to the cables 4. These legs point in the opposite direction and are provided with
