Problems solved by technology

[0003] A disadvantage of the known clamping modules for fastening on the support rail is that they are placed on the support rail from the front and thus cover the track at the rear
Increased expenditure when assembling known clamping modules due to the lack of assistance for the assembler to determine that the clamping modules are correctly seated on the support rail before operating the fixing device

Embodiment Construction

[0024] figure 1 An exemplary clamping module 10 of the present invention is shown (at Figures 2 to 4 Components of an exemplary tensioning device 20 shown in ). The tensioning device 20 has a pressure-applying sheet-metal part 21 consisting of a pressure plate 21a with two lateral flanges 21b formed thereon. The pressure plate 21a of the pressure plate part 21 is designed such that it rests at least partially on the support rail when the clamping module is assembled. A guide groove 21c is formed in at least one of the side limbs 21b.

[0025] In the exemplary embodiment, the tension element, referred to as tension bridge 22 , is designed such that it can be arranged inside pressure sheet metal part 21 . The tensioning bridge 22 has at least one guide nose 22a, which is guided in the guide groove 21c in the assembled state of the tensioning bridge 22 inside the pressure plate part 21 in such a way that the tensioning bridge 22 is positioned at the side flange 21b can move to...

Abstract

The invention relates to a clamping module for fixing on a support rail, which has a housing, a clamping device and at least one retaining pawl arranged on the clamping device. The at least one retaining pawl can be brought into a fixed position on the support rail by means of the tensioning device and can be braced in this position in order to releasably fasten the clamping module to the support rail. According to the invention, the clamping module has a signaling device with at least one signaling element arranged in the housing which can be moved along a predetermined movement path by placing the clamping module on the support rail. By means of the position of the signal element on the movement path, it can be determined from outside the housing whether the clamping module is correctly arranged on the support rail.

Description

technical field [0001] The invention relates to a clamping module for fastening to a support rail, which has a housing, a tensioning device and at least one holding claw arranged on the tensioning device, wherein the holding claw can be mounted by means of the tensioning device It enters into a fastening position on the support rail and can be braced in this position in order to detachably fasten the clamping module on the support rail. Background technique [0002] A clamping module for fastening to a support rail is known, for example, from DE 20 2011 105 337 U1. Support rails are used in electrotechnical engineering, in particular for fastening components in switchboards, switchgear cabinets, terminal boxes, etc. Here, the various electronic modules are pushed in from the side or plugged in from the front onto the support rail and locked against movement due to shocks and vibrations by means of clamping modules, in particular arranged laterally on it . The support rail...
