Description

(1) The invention is explained in more detail below in connection with the drawing, in which:

(2) FIG. 1 shows a plan view of an electrical device formed by two supply rails;

(3) FIG. 2 shows a side view of the electrical device shown in FIG. 1 with an already installed electronic device;

(4) FIG. 3 shows a sectional representation of the arrangement from FIG. 2 in which the electrical contacting can be seen; and

(5) FIG. 4 shows an electronic device, which for transporting is arranged in a transport and assembly module.

(6) FIG. 1 shows an electrical device 1, which has a first electrical supply rail 1a and a second electrical supply rail 1b. Respectively provided on the supply rails 1a, 1b are a contact area 1c and a contact area 1d.

(7) Between the two supply rails 1a, 1b is an electronic device 2, which may be for example a control device, a memory card, a circuit board populated with electronic components, etc. A heat sink 2a may be provided on the electronic device 2.

(8) In the case of the exemplary embodiment shown here, the electronic device 2 is fastened on the electrical device 1 at four fastening points 3a, 3b, 3c, 3d, which are later explained in still more detail.

(9) FIG. 2 shows in a side view the electrical device 1 and the electronic device 2 installed on it or on top of it. The electronic device 2 is represented here as a board-like element, on which a number of electronic components 2b, 2c, 2d, 2e are arranged.

(10) The two supply rails 1a, 1b of the electrical device 1 are connected to one another by way of a transverse plate 1e. Respectively protruding upwardly from an upper side of the transverse plate 1e, at the four fastening points 3a-3d (cf. FIG. 1), are a ball 4a and a ball 4b. The two balls 4a, 4b may be welded, adhesively bonded or fastened in some other way on the upper side of the transverse plate 1e. The balls 4a, 4b serve as connecting elements for connecting and fixing the electronic device 2.

(11) For this purpose, through-holes, which are slightly smaller than the diameter of the balls 4a, 4b, are provided in the electronic device 2, or in the board of the electronic device 2, at the fastening points 3a-3d (cf. FIG. 1). The board of the electronic device 2 is flexible, at least to such an extent that the slightly larger balls 4a, 4b can be pressed through the through-holes, whereby a frictional or interlocking ball clamping connection is produced.

(12) As can be seen from FIG. 2, protruding from the upper side of the electronic device 2 are resilient contact springs 5a, 5b, which press against the contact areas 1c and 1d of the contact rails 1a and 1b, respectively, and thereby establish an electrical contact.

(13) FIG. 3 shows a cross section through the arrangement shown in FIG. 2. Protruding from an underside of the board of the electronic device 2 are a number of pin- or spike-like first contact elements 6a-6e, which can engage in second contact elements 7a-7e and electrically contact them. The second contact elements 7a-7e may be connected to data lines of a bus system, for example Can bus, Flex-Ray, etc.

(14) In addition to the first contact elements 6a-6e, further contact elements 6f and 6g may be provided, by way of which the electronic device 2 is supplied with current from additional supply rails 8a and 8b, respectively.

(15) FIG. 4 shows a transport and assembly module 9, which has a housing-like component 9a, in which an interior space 9b is provided. The electronic device 2 is arranged in the interior space 9b. The contact springs 5a, 5b of the electronic device 2 engage in latching depressions 9c, 9d, which are provided on an inner side of the interior space 9b. As a result, the electronic device 2 is held in the interior space 9b.

(16) In order to protect the first contact elements 6a-6e from mechanical damage during transport, the interior space 9b, and consequently access to the first contact elements 6a-6e, is blocked by a protective element 10, which is formed here by a plate arranged displaceably in the direction of an arrow 11.

(17) It may be provided that the electronic device 2 is fixed in the transport and assembly module 9 when it is supplied by its manufacturer, the protective element 10 being in the position shown in FIG. 4 in the as-delivered condition.

(18) For installing the electronic device, the transport and assembly module 9, as shown in FIG. 4, is brought up to the electrical device 1 (cf. FIG. 1 or 2). Subsequently, the protective element 10 is displaced laterally in the direction of the arrow 11, whereby access to the first contact elements 6a-6e is enabled.

(19) In a further step, an actuating device 12, which has a rotatable actuating element 12a, is actuated. By turning the actuating element 12a, two press-out pins 12b and 12c are displaced downwardly. The press-out pins 12b, 12c press the electronic device 2 downwardly out of the interior space 9b in the direction of the second contacts 7a-7e. In this case, the electronic device 2 is “pressed” onto the balls 4a, 4b, and is thereby mechanically fixed. At the same time, during further downward pressing, the first contacts 6a-6e respectively engage in the assigned second contact 7a-7e, so that the electronic device 2 is connected not only mechanically but also electrically.

(20) When the intended position of the electronic device 2 has been reached, the transport and assembly module is removed.
