According to the invention, the carrier arrangement comprises a ground plate (6) with a plurality of ground connection elements (8.1 to 8.n) for electrical coupling to the electronic devices (2 to 5), wherein the ground plate (6) has a central connection element (9) for electrical coupling to an electrical Ground potential and at least one with at least one ground plate fastening element of the carrier (1) corresponding carrier fastening element (7) for attachment to the carrier (1).

Description

The invention relates to a support arrangement for electronic devices according to the preamble of claim 1.

From the DE 34 09 022 C2 a carrier assembly for electronic devices known. The carrier assembly comprises a carrier with a plurality of fastening elements designed as a guide rail, in which the electronic devices can be inserted. The carrier is formed from a U-shaped bent aluminum sheet with front side folded up side walls. On a bottom plate of the carrier assembly, a board is attached. Furthermore, the carrier arrangement comprises a ground connection for connecting the same to an electrical ground potential.

The invention is based on the object of specifying a comparison with the prior art improved carrier arrangement for electronic devices.

The object is achieved by a support assembly having the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

The electronic device carrier assembly includes a carrier, wherein the carrier comprises a plurality of device attachment elements for mounting the electronic devices. According to the invention, the carrier arrangement comprises a ground plate with a plurality of ground connection elements for electrical coupling to the electronic devices, the ground plate comprising a central connection element for electrical coupling to an electrical ground potential and at least one carrier attachment element corresponding to at least one ground plate attachment element of the carrier for attachment to the carrier.

The carrier assembly allows pre-assembly of the electronic devices, such as control devices, on the support and an electrical connection of the electronic devices with the ground plate during pre-assembly. This pre-assembly offers increased ergonomics and therefore easier work for a fitter. In an assembly of the carrier together with the electronic devices and the ground plate at a destination, in particular a vehicle, then only an attachment of the carrier at the destination and an electrical connection of the central connection element with the electrical ground potential, such as a vehicle body, is required. Thus, on the one hand, a minimization of a number of ground connections to be connected and, on the other hand, a significant reduction in assembly time are achieved. Due to the minimization of the number of ground connections results in a cost reduction and a reduced space. Further, due to the minimization of the ground terminals, there is a reduction in a risk that a ground terminal is not mounted. This results in a reduced reworking effort.

Embodiments of the invention are explained in more detail below with reference to drawings.

Showing:

1 schematically a plan view of a carrier with a plurality of fixed electronic devices and a fixed ground plate and

2 schematically a perspective view of a detailed representation of the ground plate according to 1 ,

Corresponding parts are provided in all figures with the same reference numerals.

In 1 is a plan view of a carrier 1 with several attached electronic devices 2 to 5 and a fixed ground plane 6 shown. 2 shows a detailed view of the ground plate 6 in a perspective view. With the electronic devices 2 to 5 These are, for example, control units for controlling vehicle functions, wherein the carrier with the control units by means not shown fastening elements on the vehicle, for example in a luggage compartment of the vehicle in the region of a wheel arch, can be fastened.

For attachment of electronic devices 2 to 5 on the carrier 1 this includes in a manner not shown a plurality of device fastening elements.

To an electrical connection of the electronic devices 2 to 5 with a common electrical ground potential is the ground plane 6 which is provided with at least one ground plate fastening element, not shown, of the carrier 1 corresponding carrier fastening element 7 for attachment to the carrier 1 includes. The carrier attachment element 7 is designed for example as a screw.

Furthermore, the ground plate includes 6 several ground connection elements 8.1 to 8.n. to an electrical coupling with the electronic devices 2 to 5 , which are designed in particular as threaded holes. In addition, the ground plate includes 6 a central connection element 9 for electrical coupling of the ground plate 6 with the electrical ground potential, in particular a vehicle body, wherein the central connection element 9 is designed in particular as a screw.

To a universal use of the carrier 1 and the ground plate 6 for a variety of applications, in particular a variety of different vehicles, are the device fasteners, the fasteners for attachment of the carrier 1 at the appropriate place of use as well as the at least one ground plate fastening element of the carrier 1 and the corresponding carrier attachment member 7 the ground plate 6 designed such that a flexible attachment of different numbers and versions of electronic devices 2 to 5 on the carrier 1 and an attachment of the carrier 1 is possible at different installation locations.
