Abstract
Abstract In an electrical system consisting of individual subassemblies, particularly in a control system composed of modules, the individual subassemblies (1, 2) comprise housings, which are adapted to be arranged in a row and for making electric line connections are provided with plug terminals for counterplug terminals on a subassembly carrier. The housings (1, 2) are secured to the subassembly carrier (4) by detachable retaining elements (27, 30, 34), particularly by swivel holders Which permit the housings to be swung up, and by snap holders (27, 28) for locking the housings when they have been swung into the row. To permit a manufacture from a few basic elements, which are to be arranged in a row of any desired length, the subassembly carrier consists of rear wall elements (4), which are adapted to secured to a profiled carrying rail (5) so that the rear wall elements (4) are arranged in a row, and the rear wall elements hold the counterplug terminals (41, 42) and have holder and counterholder parts (27, 30) for the housings (1, 2). Their widths match the module dimensions of the housings.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A modular electrical control system comprising (a) individual subassembly housings juxtaposed in a row, at least one of the housings having a width differing from the width of the other housings, which width corresponds to a basic module dimension, and the differing width being an integral multiple of the basic module dimension, (b) plug terminals and counterplug terminals arranged on each subassembly housing for making electrical line connections, (c) rear wall elements having identical widths corresponding to the basic module dimension, (d) detachable retaining means for securing the subassembly housings on the rear wall elements, the retaining means comprising (1) respective retaining extensions and cooperating detents on the rear wall elements and on the subassembly housings for detachably securing the housings to the rear wall elements, (e) a profiled carrying rail whereon the rear wall elements are juxtaposed in a row, and (f) locking means holding the rear wall elements on the carrying rail, the locking means being adapted to be opened from a front side of the rear wall elements.
Claim 2
Dependent Claim
171 words
A modular electrical control system comprising (a) individual subassembly housings juxtaposed in a row, at least one of the housings having a width differing from the width of the other housings, which width corresponds to a basic module dimension, and the differing width being an integral multiple of the basic module dimension, (b) plug terminals and counterplug terminals arranged on each subassembly housing for making electrical line connections, (c) rear wall elements having identical widths corresponding to the basic module dimension, (d) detachable retaining means for securing the subassembly housings on the rear wall elements, the retaining means comprising (1) respective retaining extensions and cooperating detents on the rear wall elements and on the subassembly housings for detachably securing the housings to the rear wall elements, (e) a profiled carrying rail whereon the rear wall elements are juxtaposed in a row, and (f) locking means holding the rear wall elements on the carrying rail, the locking means being adapted to be opened from a front side of the rear wall elements.
Claim 3
Dependent Claim
75 words
The modular electrical control system of claim 1, further comprising spring clips on the rear wall elements for joining adjacent ones of the rear wall elements, each spring clip being a plastic molding having spring legs protruding through lateral openings in the rear wall elements and being adapted to snap into associated lateral openings in the adjacent rear wall element and to be disengaged from the associated lateral openings by actuation from the front side.
Claim 4
Dependent Claim
120 words
The modular electrical control system of claim 1, wherein the carrying rail has a hat profile and two flanges extending therefrom, a rear side of each rear wall element defining a recess for receiving the carrying rail, and the locking means comprises hooks engaging one of the carrying rail flanges for hanging the rear wall elements on the one carrying rail flange and pivotal catches having a wedge surface for engaging the other carrying rail flange, the hooks and catches being mounted on the rear wall elements, and the rear wall elements being pivotally movable into a locking position when they are hung and the wedge surface of the catches clamping the other carrying rail flange in said locking position.
Claim 5
Dependent Claim
33 words
The modular electrical control system of claim 3, wherein the pivoted catch has a pivot extending to the front side of the rear wall element, the pivot being provided with a position indicator.
Claim 6
Dependent Claim
36 words
The modular electrical control system of claim 4, wherein the position indicator is a disk defining a receiving opening for an actuating implement for pivoting the catch from the front side of the rear wall element.
Claim 7
Dependent Claim
56 words
The modular electrical control system of claim 1, wherein the plug terminals are arranged at one side of the subassembly housings and the counterplug terminals are arranged at an opposite side thereof, the plug terminal on one of the rear wall elements cooperating with the counterplug terminal on an adjacent one of the rear wall elements.
Claim 8
Dependent Claim
52 words
The modular electrical control system of claim 1, wherein the one housing comprises two shell halves having a combined width corresponding to the basic module dimension and an interposed piece having a width corresponding to an integral multiple of the basic module dimension, and the other housings comprise two such shell halves.
Claim 9
Dependent Claim
27 words
The modular electrical control system of claim 7, wherein the housings define window openings at a front side thereof, and comprising doors or shutters selectively insertable therein.
Claim 10
Dependent Claim
22 words
The modular electrical control system of claim 7, comprising display windows selectively insertable in openings at a front side of the housings.
Claim 11
Dependent Claim
24 words
The modular electrical control system of claim 7, comprising slide tracks in the interior of the housings for inserting built-in elements in the housings.
