Embodiment Construction

[0039] figure 1 Shown is a section through a carrier 2 having the shape of a cylindrical segment, the printed circuit board 1 being arranged on the concavely curved face 8 of the carrier 2 . The printed circuit board 1 is tensioned at one end in the fastening element 4 . The fastening element 4 is fixedly connected to the surface 8 of the carrier 2 . A tension force F is exerted on the free end of the printed circuit board 1 by means of second means 3 , illustrated as tension springs. Tensile stresses thus arise within the printed circuit board 1 , by means of which the printed circuit board 1 is pressed against the concavely curved surface 8 of the carrier 2 . Tensile forces can alternatively and additionally be applied at other locations between the two ends of the printed circuit board 1 .

Abstract

A retaining facility for clearance-free fixing of a printed circuit board onto a one-dimensional curved surface is provided. In the direction of curvature of the one-dimensional curved surface, a tensile or compressive force acts on the printed circuit board or on at least one first connection device connected to the latter, with the printed circuit board being bent and pressed onto the curved surface. In this way the printed circuit board is held solidly and with little vibration on the surface even when acted on by centrifugal forces.

Description

technical field [0001] The invention relates to a holding device for the gap-free fastening of a printed circuit board on a one-dimensionally curved surface as specified in claim 1 or 2 . Background technique [0002] In constructing electrical and electronic equipment, assembled printed circuit boards are often arranged and secured within or on the housing of the equipment. In many cases, long elongated printed circuit boards must be affixed to the outer surface of the cylinder or to the inner surface of the hollow cylinder. Especially for contactless signal transmission in computed tomography devices, printed circuit boards have to be fastened over lengths of more than two meters on the inner and outer sides of rings with a diameter greater than 1.6 m. Usually, the printed circuit board is glued and / or screwed to the ring for this purpose. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide another holding device...
