1 Claim.

The present invention relates to an arrangement for high-frequency systems, and more particularly to a design for simplifying the mounting operation of the individual element assemblies forming part of a circuit arrangement in such systems.

It is well known in connection with high-frequency carrier and amplifier systems to provide the individual element assemblies of a circuit arrangement, for instance filter devices, amplifying tubes, oscillatory circuits and the like, in boxes of equal cross section, and to mount said boxes in a rack. According to known arrangements, the individual box-shaped element assemblies have been mounted separately one from another by connecting straps, screws and similar means. However, such measures involve the disadvantage of a considerable loss of time during the mounting operation, while a great number of fixing means is required.

These and other disadvantages are obviated according to the present invention, in which the box-shaped element assemblies of equal cross section and forming part of a circuit arrangement are fixed in their relative positions by insertable clamping means, so as to attain a simple mounting and an easy interchangeability.

The invention will be more readily understood from the following description in conjunction with the attached drawing in which Fig. 1 illustrates a front elevation of an embodiment according to the invention, while Fig. 2 shows a side elevation of the embodiment illustrated in Fig. 1.

In the drawing, a rack I is provided with a frame 2. Closed box-shaped element assemblies 3 of sheet metal, for example, are placed on the frame 2. The front walls of the boxes may be of an insulating material or of sheet metal. Soldering tabs L to which the lead-in conductors and connecting conductors may be attached are provided on the front walls of the boxes. The oscillatory circuits, amplifying tubes and the like (c1. air-v1) are placed in the boxes 3 of equal cross sectional area, that is to say, the walls facing each other are equal. Holes 5 are provided along the entire length of the frame 2 and are adapted to receive clamping rods 4. These rods carry screws 6. The rods may optionally be inserted in holes of the frame in correspondence with the number of elements assemblies to be mounted in the frame, whereupon the box-shaped element assemblies are rigidly clamped together by tightening the screw. The individual element assemblies may be guided in rails 1 attached to the frame 2 in order to provide a possibility for motion in one direction only. The complete arrangement is protected by a cover 8.

What is claimed is:

A supporting and clamping rack for supporting and clamping a plurality of boxes comprising a lower supporting member being relatively long with respect to its width and having holes distributed longitudinally therein, guide means along the longitudinal edges of said member, said means being spaced apart a distance substantially equal to the depth of said boxes, an upper member having holes therein, said holes being distributed along said member in the same manner as the holes in said lower member, uprights between said members for spacing said members from each other a distance at least equal to the height of said boxes, and means for preventing motion of said boxes longitudinally of said members, said means being spaced apart a distance at least equal to the combined widths of boxes mounted on said lower member and at least one of said means comprising a rod adapted to be inserted between said members in one of the holes in said upper member and in a corresponding hole in the lower member and a screw passing through said rod at right angles thereto and being threaded to said rod, said screw being in adjustable contact with a side of an end one of said boxes.
