Abstract

The printed circuit board has a T-shaped slot (4) in one edge to provide strain protection for the flat flexible connection cable (3). The bared ends of the wires (31-34) projecting from the cable fit into contact holes (11-14) located in a row parallel to the T's crosspiece and just next to this crosspiece in body of the board. The cable is inserted into the slot's stem sideways and then turned to lie in the crosspiece. The wires are soldered into the holes. The advantage lies in simplicity, no extra components are needed for tension relief.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung, die eine mechanisch besonders zuverlässige Festlegung des Bandkabels unter Zugentlastung gewährleistet, ist die Längsausdehnung des Durchbruchs geringer als die Breite des Bandkabels.According to a further advantageous embodiment of the invention, the a mechanically particularly reliable fixing of the ribbon cable with strain relief guaranteed, the length of the opening is less than the width of the Ribbon cable.

Die Vorteile der vorliegenden Erfindung liegen insbesondere darin, daß trotz des Verzichts auf zusätzliche Bauteile ein mit der Schaltungsplatte verbundenes =Bandkabel besonders elastisch zugentlastet festgelegt ist, wozu keine aufwendigen Arbeitsvorgänge erforderlich sind. Dabei ist eine erfindungsgemäß ausgebildet#e Zugentlastung wesentlich wirksamer als übliche, mit zusätzlichen Bauteilen ausgebildete Zugentlastungen.The advantages of the present invention are in particular that that despite the fact that no additional components are used, one is connected to the circuit board = Ribbon cable is set in a particularly elastic, strain-relieved manner, for which no complex Operations are required. In this case, one is designed according to the invention Strain relief much more effective than usual, designed with additional components Strain relief.

Die Erfindung wird nachfolgend an den Figuren 1 und 2 näher erläutert. Dabei zeigt die Figur 1 eine erfindungsgemäß ausgebildete gedruckte Schaltungsplatte ohne Bandkabel. Figur 2 zeigt eine erfindungsgemäße gedruckte Schaltungsplatte mit einem Bandkabel in einer perspektivischen Ansicht.The invention is explained in more detail below with reference to FIGS. 1 and 2. FIG. 1 shows a printed circuit board designed according to the invention without ribbon cable. Figure 2 shows a printed circuit board according to the invention a ribbon cable in a perspective view.

Zwischen dem der dieser Kontaktreihe 11, 12, 13, 14 zugeordneten Rand 10 der Schaltungsplatte 1 und der Kontaktreihe 11, 12, 13, 14 liegt der zum Rand 10 hin teilweise offene längliche Durchbruch 2, der am Rand 10 durch die schmalen Stege 21 und 22 der Schaltungsplatte 1 begrenzt ist. Diese Stege 21 und 22 bilden einen mittig angeordneten und senkrecht zum Durchruch 2 verlaufenden durchgehenden Einschnitt 4, durch den der Durchbruch 2 zum Rand 10 hin geöffnet ist. Diese Stege 21 und 22 bilden für ein in den Durchbruch 2 geführtes Bandkabel eine federelastische Zugentlastung.Figure 1 shows in a plan view a printed according to the invention Circuit board 1 with the row of contacts 11, 12, 13, 14, which consists of the individual contacts 11, 12, 13 and 14 is constructed. Between that of this contact row 11, 12, 13, 14 associated edge 10 of the circuit board 1 and the row of contacts 11, 12, 13, 14 is the elongated opening 2, which is partially open towards the edge 10, and the one at the edge 10 is limited by the narrow webs 21 and 22 of the circuit board 1. These Web 21 and 22 form a centrally arranged and perpendicular to the opening 2 continuous incision 4 through which the opening 2 opens towards the edge 10 is. These webs 21 and 22 form a ribbon cable guided into the opening 2 a spring-elastic strain relief.

Figur 2 zeigt in einer perspektivischen Ansicht eine mit einem Bandkabel 3 verbundene gedruckte Schaltungsplatte 1 gemäß der Erfindung. Das Bandkabel 3 ist mit seinen Anschlußenden 31, 32, 33 und 34 an die Kontakte 11, 12, 13 und 14 festgelötet.
