Device for fixing two modules parallel to each other

technical field

The invention relates to a device for fastening a module to the side wall of another module.

Background technique

A modular drive system is known from Siemens catalog DA 65.11-2001 entitled "SIMOVERT MASTERDRIVES Motion Control", chapter 6, page 6/47. The modular drive system shown in FIG. 6/42 has a capacitor module, a power supply module with an operating part and 7 inverter modules. These modules are spatially arranged side by side with each other. The modules are electrically conductively connected to one another by means of an intermediate circuit track. Since the modules are all detachably fastened to a mounting plate, in particular on the rear wall of a switch cabinet, and their fronts form a continuous front of the modular drive system, the modules must all be of the same length. Also, the modules of the drive system are all of the same height, so that the modular drive system has a cuboid structural shape. The modules of the modular drive system differ only in their width.

The width of each module is determined by the circuits that need to be installed in the module. In inverter modules the width priority depends on the power of the inverter. In order for the cuboid shape of the modular drive system to be free from unevenness, even the smallest power inverter modules for one shaft must be housed in a module of predetermined height and length. Such a module is likewise fastened releasably to a mounting plate, in particular to the rear wall of a switch cabinet.

Another embodiment of a modular drive system is known from Siemens catalog DA 65.4-2001 entitled "SIMO DRIVE 611 universal und POSMO", chapter 6, page 6/26. Such modular drive systems differ primarily in the design of the modules and their electrical connections. The modules of such a modular drive system are also arranged spatially next to each other and are detachably fastened to a mounting plate, in particular to the rear wall of a switch cabinet. In such a modular drive system, the front side of the individual modules likewise forms the front side of the modular drive system. The mechanical construction of the modules differs here likewise only in their width, in order not to interfere with the uniform cuboidal shape of the modular drive system.

In these above-mentioned modular drive systems, each module must have an upper and a lower fixed connection plate in order to enable them to be detachably fixed to the mounting plate. A tool is therefore always required for fastening a module, provided that the mounting plate has corresponding holes.

Contents of the invention

The object of the present invention is to propose a device for the plane-parallel fastening of a module on the side wall of another module, wherein no tools are required for the fastening.

This object is achieved according to the invention by a connecting element having a connecting device, wherein the side walls of the connecting device are each provided with a guide device with two guide lugs, a locking device and a stop device, That is, between the two guide pieces and between the locking device and the stop device are arranged opposite to each other, and a clamping device is respectively provided on the plane side of the connecting device, the clamping device The side walls slope inwardly.

By providing at least two connecting elements, the side wall of the other module has a corresponding receiving device for each connecting element and the side wall of the module to be fastened facing this side wall has a corresponding locking. device, so that the module to be fixed can be fixed simply by inserting it on the side wall of another module. Therefore no tools are required. Before one module can be plugged onto the side wall of the other module, the connecting element must first be inserted into a corresponding receptacle on the side wall of the other module. Here, the corresponding receptacle is advantageously designed such that the connecting element can be mounted in the receptacle of the side wall of a module without falling out.

Each locking device in the side wall of a module to be fixed is a slot with a centrally located elongated hole. The groove is stamped so wide that the two opposite side walls of the module to be fastened and the other module are still plane-parallel to one another despite the latched connecting elements. That is to say that the two sides are in contact over a large area. Furthermore, each groove is designed for a connecting element in such a way that the connecting element can be clamped in the groove.

The elongated hole in the side wall of the other module and the elongated hole in the side wall of the module to be fastened each have opposite flanges for clamping a connecting element. The flange opposite to the position of the elongated hole in the side wall of the other module is arranged in the lower region of this elongated hole with respect to a connecting element, whereas the elongated hole in the side wall of the module to be fixed The opposite flange is provided in the upper region of the elongated hole.

By using at least two connecting elements, a module can be fixed plane-parallel to the side wall of another module without the use of tools, especially on an already detachably fixed part of a module drive system on the side wall of the module. The number of connecting elements to be used depends on the size and weight of the modules to be fixed.

The connecting element has a connecting device, a guide device, a locking device and a stop device. In an advantageous embodiment, the devices have a structural shape. In particular, the connecting element according to the invention is an injection molded part.

Further advantageous developments of the connecting element can be obtained from the dependent claims.

Detailed ways

FIG. 1 shows a plan view of a connecting element 2 according to the invention of a device according to the invention for fastening a module on a side wall of a further module in a plane-parallel manner. According to this view, the connecting element 2 has a connecting device 4 , a guide device 6 , a locking device 8 and a stop device 10 . As the latching device 8, a latching lug fastened on one side to the connecting device 4 is used. Two opposite guide lugs 6 ₁ and 6 ₂ are used as the guide device 6 , which are likewise attached to the connecting device 4 on one side. The stop device 10 is mounted on the connecting device 4 on the same side opposite to the locking piece. In order to simplify the production of the connecting element 2 in mass production, the connecting element 2 is made of plastic and is designed as an injection-molded part.

It can be seen from FIG. 2 , which shows a side view of the connecting element 2 shown in FIG. 1 , that the connecting device 4 of each connecting element 2 has two clamping devices 12 and 14 . The side walls of each clamping device 12 and 14 opposite to the guide pieces ₆₁ and ₆₂ are inclined inwardly. Furthermore, the end faces 16 and 18 of the guide pieces ₆₁ and ₆₂ are beveled. The inclination of the end faces 16 and 18 depends on the inclination of the side walls of the slot 20 punched in the side wall 22 of the module 24 to be fixed (FIG. 3). In order to give each guide piece ₆₁ and ₆₂ a predetermined rigidity with as little material as possible, they are ribbed.

FIG. 3 shows a section through the fastening points of the device according to the invention for fastening the module 24 on the side wall 26 of the other module 28 in a plane-parallel manner. At this fastening point, the side wall 26 of the further module 28 has an elongated hole 30 which has opposite flanges 32 and 34 for fastening the connecting element 2 . These two flanges engage behind the inwardly inclined side walls of the clamping means 12 of the connecting means 4 of the connecting element 2 . The slot 20 in the side wall 22 of the module 24 likewise has an elongated hole located approximately in the center of the slot 20 . This elongated hole also has opposite flanges 36 and 38, which are opposite to the flanges 32 and 34 on the elongated hole 30 of the side wall 26 of the other module 28, which fasten the clamp of the connecting device 4 of the connecting element 2 from behind. The sloped side walls of the tightening device 14. The inclined end faces 16 and 18 of the two opposite guide tabs ₆₁ and 62 of the connecting element ₂ bear against the side wall 22 of the groove 20 . The connecting element 2 and thus the module 24 to be fixed are thus clamped in the groove 20 in the correct position relative to the other module 28 . In order that the module 24 cannot be pulled out of the side wall 26 of the other module 28 without effort, a stop device 10 is provided on the connecting element 2, the end faces of which are likewise bevelled. Its slope corresponds to the slope of the groove 20 . As a result, the connecting element is clamped from three sides with the groove 20 of the side wall 22 of the module 24 to be fastened by means of two opposing guide tabs ₆₁ and ₆₂ and by means of a stop device 10 . In order not to require an unnecessarily high force, the contact surfaces are inclined, whereby the dismounting force can be determined here by means of the inclined angle.

FIG. 4 shows another module 28 in a perspective view. On the side wall 26 of this module 28 a plurality of connection elements 2 have been inserted. The connecting elements 2 are accommodated in the elongated holes 30 and locked with the side wall 26 of the other module 28 in a fall-proof manner by means of latching tabs 8 . The opposite guide lugs ₆₁ and ₆₂ of each connecting element 2 bear on the side wall 26 of the module 28 . The module 28 relates to a compact device in an industrial electronics system in book-size format. Such a compact device for industrial electronics can be a module of a modular drive system, for example a power supply module or an inverter module.

FIG. 5 shows a perspective view of another module 28 shown in FIG. 4 and a module 24 secured to its side wall 26 . Regardless of the size of the module 24 to be fixed, the front side of this module 24 is arranged in the front side of the module drive system. In order to fix this module 24 on the side wall 26 of another module 28, this module 24 leans on the side wall 26 of another module 28 with its side wall 22 which cannot be seen here, here, This module 24 protrudes outwardly over a further module 28 . After this, the module 24 is moved downwards until the connecting element 2 engages with the corresponding elongated hole of the groove 20 on the side wall 22 of the module 24 . In this locked state, the two modules 24 and 28 are at the same height. In order to detach one module 24 from the other module 28, the described movement sequence is carried out in the opposite direction, and a predetermined force should be applied to overcome the latching. The module 24 to be fixed can also have the dimensions of another module.
