DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an electrical device, in particular a switching and controlling device for a motor vehicle.
BACKGROUND INFORMATION
German Patent Application No. 1 33 10 477 A1 describes a device which includes a block-shaped housing, a component parts support located in the housing, a plug-in connector extending out of the housing at a front-end opening, and a frame-shaped retaining element, which surrounds the plug-in connector, overlapping it in part, and fixes it in position on the housing.
The plug-in connector represents a separate, replaceable part and includes a plug element made of plastic, in which support segments of contact elements are supported, the end segments of the contact elements constituting contact segments for coupling with mating contact elements of a mating connector and connector segments for connecting to the component parts support.
To be mounted on the device, the plug-in connector is attached to the retaining body using screws, and the retaining body to the housing of the device using snap-in connections. This manner of furnishing an electrical device with contact elements as a connecting means within the framework of a separate plug-in connector is unfavorable from a production engineering standpoint, and it is connected to high manufacturing costs. In particular, for such a device, the plug-in connectors must be constructed, inspected, and placed in intermediate storage. After the plug-in connector is conveyed to the device, the plug-in connector is attached to the device in assembly steps.
If the device is exposed to high mechanical stresses, for example, because it is mounted directly on an internal combustion engine of a motor vehicle, then additional reinforcing (safety) measures must be undertaken. For example, a reinforcing lacquer may be applied to the screw connections to prevent a shattering of the electrical connections between the connecting segments of the contact elements and the connecting points of the component parts support. This leads to the manufacturing process of the device being cost-intensive.
SUMMARY OF THE INVENTION
The electrical device of the present invention overcomes the above-described problems. In accordance with an exemplary embodiment of the present invention, a retaining element is mounted in a recess of a housing of the device, the retaining element extending into the recess transversely with respect to a coupling direction of contact elements of the device.
When a filling body is integrally inserted into the recess, the filling body closing the recess and having a positive fit with support segments of the contact elements and with the retaining part, a plug-connector housing is created which, as an integral component of the housing of the electrical device, gives the device a high degree of operational reliability even under increased mechanical stresses, and makes possible a cost-effective manufacturing process of the device.
BRIEF DESCRIPTION OF THE DRAWING
The FIGURE illustrates a sectional view of an exemplary embodiment of the present invention, and, in particular, the FIGURE shows parts of a housing and of a plug-connector housing of an electrical device.
DETAILED DESCRIPTION OF THE INVENTION
As shown in the FIGURE, an electrical device 11, in particular a switching and controlling device for a motor vehicle, includes a housing 12, which is block-shaped and is made of metal. Alternatively, the housing may also be manufactured out of plastic.
A component parts support (not shown) is located in housing 12, the component parts support being fitted with electrical and/or electronic components and having electrical connecting points for connection.
On a base 13 of housing 12, opposite a top surface 14 of housing 12, a recess 16 or, alternatively, a plurality of recesses 16 is formed. The recess may be closed using a cover. Recess 16 is provided for accommodating contact elements 17, which are connected to end-side connecting segments having associated connecting points of the component
