Definitions

• the invention relates to a device for fastening a module to a side wall of another module.
• a modular drive system is known from the Siemens catalog DA 65.11 - 2001 with the title "SIMOVERT MASTERDRIVES Motion Control", chapter 6, especially page 6 / I.
• the modular drive system shown in Fig. 6/42 has a capacitor module, a supply module with control panel and seven inverter modules. These modules are arranged side by side. These modules are electrically connected to each other by means of an intermediate circuit busbar. Since these modules are all releasably attached to an assembly wall, * in particular a rear wall of a control cabinet, and their front sides form a continuous front side of the modular drive system, these modules must all be of the same length. Likewise, these modules of the drive system are all of the same height, so that this modular drive system has a cuboid shape. The modules of this modular drive system differ only in their widths.
• each module is determined by the electrical circuit that must be housed in the module.
• the width of the inverter modules depends primarily on the power of the inverter. So that the cuboid design of the modular drive system is not jagged, even an inverter module with the lowest output for an axis must be arranged in a module, the height and length of which are already predetermined.
• Such a module is also releasably attached to the mounting wall, in particular on a rear wall of a control cabinet.
• a further embodiment of a modular drive system is known from the Siemens catalog DA 65.4 - 2001 with the title "SIMODRIVE 611 universal and POSMO", chapter 6, in particular page 6/26. This modular drive system differs primarily in the design of its modules and their electrical connections.
• the modules of this modular drive system are also arranged side by side and releasably attached with a mounting wall, in particular a rear wall of a control cabinet.
• a mounting wall in particular a rear wall of a control cabinet.
• the front of the individual modules form the front of the modular drive system.
• the modules differ only mechanically in their width, so that the uniform cuboid design of the modular drive system is not disturbed.
• each module must have an upper and lower fastening tab so that it can be detachably attached to a mounting wall.
• a tool is therefore always required to fasten a module, provided that the mounting wall has corresponding bores.
• the invention is based on the object of proposing a device for the plane-parallel fastening of a module to a side wall of a further module, no tool being required for fastening.
• a side wall of the further module has a corresponding receiving device for each coupling element and a side wall of the module to be fastened facing this side wall has a corresponding locking device for each coupling element, the module to be fastened can simply be plugged into the side wall of the attached further module become. No tools are needed anymore.
• the coupling elements Before a module can be plugged into the side wall of another module, the coupling elements must first be inserted into the corresponding receptacles of the side wall of the further module.
• these corresponding receiving devices are advantageously designed such that the coupling elements can each be arranged in a captive manner in the receiving devices of the side wall of a module.
• Each locking device in the side wall of a module to be fastened is a depression with an elongated hole arranged in the center.
• the depression is stamped so far that the two opposite side walls of the module to be fastened and of the further module are plane-parallel to one another despite the latched coupling elements. In other words, these two side surfaces touch each other over a large area.
• each depression is designed corresponding to a coupling element in such a way that it can be braced in the depression.
• the elongated holes in the side wall of the further module and the elongated holes in the side wall of the module to be fastened each had opposite lugs for clamping a coupling element.
• the opposite lugs of the elongated hole are arranged in the side wall of the further module in the lower region of this elongated hole, whereas the opposite lugs of the elongated hole are arranged in the side wall of the module to be fastened in the upper region of this elongated hole.
• a module can be attached to a side wall of another module, in particular an already detachably attached module of a modular drive system, without the use of a tool.
• the number of headers to use pelieri depends on the size and weight of the module to be attached.
• the coupling element has a connecting means, a guide means, a latching means and a stop means. In an advantageous embodiment, these means have a design.
• the coupling element according to the invention is a plastic injection molded part.

• the coupling element 2 has a connecting means 4, a guide means 6, a latching means 8 and a stop means 10.
• locking means 8 a latching tab is provided which is fastened on one side to the connecting element 4.
• guide means 6 two opposite guide plates 6 ⁇ and 6 2 are provided, which are also attached to the connecting element 4 on one side.
• the stop means 10 is also attached on one side to the connecting means 4.
• the coupling element 2 consists of plastic and is designed as a plastic injection-molded part.
• FIG. 2 which shows a side view of the coupling element 2 according to FIG. 1, shows that the connecting means 4 of each coupling element 2 has two clamping means 12 and 14.
• the side walls of each clamping means 12 and 14 opposite the guide plates 6 ⁇ and 6 2 are chamfered inwards.
• the end faces 16 and 18 of the guide tabs 6 and 6 2 are chamfered.
• the inclination of these end faces 16 and 18 is based on the inclination of the side walls of an embossed depression 20 in the side wall 22 of a module 24 to be fastened (FIG. 3). So that each guide lens 6 ⁇ and 6 2 has a predetermined rigidity with as little material as possible, these are ribbed.
• FIG 3 shows a sectional view through a fastening point of the device according to the invention for the plane-parallel fastening of a module 24 to a side wall 26 of a further module 28.
