Frame for connection to at least one printed circuit board and system comprising at least one printed circuit board and frame

Abstract

A frame for connection to at least one printed circuit board is proposed, wherein the frame comprises: outer struts forming the frame, screwing points distributed over the outer struts on a frame side to be connected to a printed circuit board, and positioning domes arranged on the same side, distributed over the outer struts, and formed as fixing points. Furthermore, a system comprising a first printed circuit board and a frame is provided, wherein a surface of the first printed circuit board has screw holes and openings, and wherein the screwing points and the positioning domes of a first frame side of the frame are arranged such that they correspond to the screw holes and openings of the first printed circuit board, and wherein the first printed circuit board is connected to the first frame side of the frame via the screwing points.

[2] Frame (100) according to claim 1, wherein opposing outer struts (101) are mechanically connected to one another by means of one or more ribs (104). [3] Frame (100) according to claim 2, wherein screwing points (102a, 102b) are arranged on opposite sides of the frame at different positions such that they are not arranged one above the other. [4] Frame (100) according to one of the preceding claims, wherein an auxiliary element (105) for cable guidance and / or cable fixing is attached to at least one outer edge region of the frame (100), preferably formed integrally with the frame (100), and / or wherein the frame (100) consists of an electrically non-conductive or weakly conductive material. [5] System comprising a first printed circuit board (1) and a frame (100) according to one of the preceding claims, wherein a surface of the first printed circuit board (1) has screw holes and openings (11), and wherein the screwing points (102a) and the positioning domes (103) of a first frame side of the frame (100) are arranged such that they correspond to the screw holes and openings (11) of the first printed circuit board (1), and wherein the first printed circuit board (1) is connected to the first frame side of the frame (100) via the screwing points (102a). [6] System according to claim 5, further comprising a second circuit board (2) having screw holes and openings (21) on one surface, and wherein the frame (100) has, on a second frame side opposite the first frame side, screwing points (102b) and positioning domes (103) which correspond to the screw holes and openings (21) of the second circuit board (2), and wherein the second circuit board (2) is connected to the second frame side of the frame (100) via the screwing points (102b). [7] System according to claim 6, wherein the second circuit board (2) has a smaller circumference than the first circuit board (1), and wherein the circumference of the frame (100) corresponds at least to the circumference of the second circuit board (2). [8] System according to claim 6 or 7, wherein the positioning domes (103) are arranged on both sides of the frame (100) in such a way that the two circuit boards (1, 2) can be blindly connected to one another electrically and / or signal-wise by means of at least one connector system arranged on the mutually facing surfaces of each circuit board (1, 2). [9] System according to one of claims 6 to 8, wherein an adhesive is provided on a part of the frame, in particular an outer side of a bottom of a screwing point (102a, 102b), or a region of the circuit board (1, 2) opposite the bottom, in such a way that it fastens the frame (100) and the circuit board (1, 2) to one another at this region. [10] Electronic module, comprising - a housing with components arranged therein for controlling an electric drive of a motor vehicle, comprising power electronics and at least one heat sink, and - the system comprising at least one circuit board (1, 2) and a frame (100) according to one of claims 5 to 9, wherein a fastening means is guided through each of the screwing points (102a, 102b) of the frame (100) and is brought into engagement with the associated screw holes in the circuit board (1, 2), and wherein the first circuit board (1) is fastened to and / or in the housing.
