BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a housing for receiving electric control devices, in particular for motor vehicles, which is closable with a cover and wherein a central connecting plate is provided which has conductor paths and detachable connecting means for the voltage supply, and a sensor for each electric control device, whereby the control devices are provided with connecting means for a detachable connection with the control connecting plate and for a detachable connection to a laced wiring harness which feeds output signals of the control devices to the aggregates being controlled, whereby all connecting means are mounted in the closed housing.
Such a combination of a housing with the electric devices is already known, wherein all electric control devices which have to be mounted in the motor compartment of the motor vehicle are disposed in such a manner that numerous additional parts must be screwed on those devices. Thereby, it is disadvantageous that the heat discipation losses from the control devices, which are mounted in the tight housing, are prevented by the resistance at the many heat transfer locations, so that the insufficiently cooled control devices are no longer operable in a short time due to heat influences. Furthermore, with the numerous control devices which are mounted in the housing it is not assured that in case of assembly or servicing each of the control devices is mounted so that heat discipation losses are carried off.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a housing for receiving different electric control devices, in particular for motor vehicles, for example, for an antiblocking system, drive control, motronic, ignition system, wherein it is possible to easily and detachably couple each control device with a large face directly to the housing for drawing off the energy heat and which is provided with simple means assuring a safe mounting and heat energy drawing off from the control devices.
The objects of this invention are attained by a housing for electric control devices, in which the electric control devices with their associated base face are pressed with a large face area against the housing by means of a simple clamping or locking device for each control device or a common device for all control devices, whereby this device or devices are so shaped that the housing with the lid can only be closed after all the control devices are properly mounted in the housing.
Particularly advantageous are the directly insulated or noninsulated disposition of the structural elements to be cooled on the base plate which acts as a cooling part. Moreover, the resilient tolerance compensation means which is mounted as a safety assembly are directly integrated in the clamping and locking device, so that during an insufficient mounting of a control device in the housing and thereby a poor cooling of the device, the lid cannot be tightly close the housing. The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 illustrates a sectional view of the housing with five control devices in a modular arrangement;
FIG. 2 is a section through the housing along line II--II of FIG. 1;
FIG. 3 is a section through the housing along line III--III in FIG. 2;
FIG. 4 is a partial section of the housing with a clamping and locking device; and
FIG. 5 is a partial sectional view of a modification of the device in accordance with FIG. 4.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A housing 1, for example, made from light metal is substantially shaped with a rectangular cross section. Parallel guide grooves 4 are molded on two opposite positioned inner walls
