239000004020 conductor Substances 0 claims abstract description 69
A control module is provided, in particular for a motor vehicle transmission, with a first housing part 6, on which an electronic circuit part 7 is located, a second housing part 14, and with a carrier 2, on which a flexible conductor film 9 is located; the flexible conductor film 9 is electrically connected—in a housing interior 16 located between the first housing part and the second housing part—with the circuit part and the electrical components 4, 3 mounted on carrier 2 outside the housing interior; a stack-shaped design is provided, with which
carrier 2, 2 a, 2 b rests, with a first side, on an interior side 6 a of first housing part 6 on which the circuit part is mounted,
circuit part 7 is located in a recess 31 in carrier 2, 2 a, 2 b,
flexible conductor film 9 is located on the second side of carrier 2, 2 a, 2 b, which faces away from first housing part 6, and
second housing part 14 is mounted on flexible conductor film 9.
The present invention relates to a control module, in particular a control module for a motor vehicle transmission, with the features listed in the preamble of independent claim 1.
The inventive control module with the characterizing features of claim 1 requires particularly little assembly effort and can be manufactured cost-effectively. With a stack-shaped design, with which the carrier—which bears, via a first side, against an interior side of the first housing part on which the circuit part is mounted, and with which the circuit part is located in a recess in the carrier, the flexible conductor film is located on the second side of the carrier which faces away from the first housing part, and the second housing part is placed on the flexible conductor film, there is no need to laminate the flexible conductor film on the first housing part, on which the circuit part is mounted, and it is attained—in a particularly advantageous manner—that the control module can be composed essentially of an assembly for the connection functions, an assembly for the electronics functions, and a cover part. Particularly advantageously, the two assemblies can be manufactured and pretested separately, and then simply stacked in position. The electrical interface between the two assemblies can be designed such that the two assemblies can be connected electrically in a simple, robust manner.
FIG. 7 shows a seventh exemplary embodiment of the present invention. In this exemplary embodiment, carrier 2 is designed as a connecting part in area 2 b of adhesive layers 28, 29, and fastening elements 15 are made partially of metal, preferably aluminium. The remaining part of carrier 2 is preferably designed as an injection-moulded part. This results in the advantage that similar materials with similar expansion coefficients can be bonded in the region of the adhesive bonds.
It is understood that the exemplary embodiments shown can also be combined with each other, and that the present invention includes, e.g., configurations with which only one of the sealing elements in FIG. 1 is replaced with a sealing bond, e.g., one of the sealing bonds in FIGS. 6 and 7 is replaced with a sealing element. Combinations of the exemplary embodiments shown in FIG. 4 and/or FIG. 6 with the exemplary embodiments in FIGS. 6 and 7 are also possible, of course.
1. A control module, in particular for a motor vehicle transmission, which includes a first housing part (6), on which an electronic circuit part (7) is located, a second housing part (14), and a carrier (2), on which a flexible conductor film (9) is located; the flexible conductor film (9) is electrically connected—in a housing interior (16) located between the first housing part and the second housing part—with the circuit part and the electrical components (4, 3), characterized by a stack-shaped design, with which
the second housing part (14) is mounted on the flexible conductor film (9).
2. The control module as recited in claim 1,
the carrier (2, 2 a) has a two-component configuration, with a first frame part (2 a) which encloses the circuit part, and a support part (2) which encloses the frame part; the frame part (2 a) is separated from the support part (2) via an intermediate space (32) in which a first sealing element (12) is located, and bears, in a sealing manner, against the interior side (6 a) of the first housing part (6), and against the flexible conductor film (9). (FIG. 1, FIG. 4, FIG. 5)
3. The control module as recited in claim 1,
a sealing adhesive (28) is located between the carrier (2, 2 b) and the interior side (6 a) of the first housing part (6). (FIG. 6, FIG. 7)
4. The control module as recited in claim 1,
a second sealing element (13) is provided, which bears, in a sealing manner, against the flexible conductor film (2) and the second housing part (14). (FIG. 1, FIG. 4, FIG. 5)
5. The control module as recited in claim 1,
a sealing adhesive (29) is located between the second housing part (14) and the conductor film (9). (FIG. 6, FIG. 7)
6. The control module as recited in claim 1,
a cover (18), which is secured to the carrier (2, 2 a), is placed on an area of the flexible conductor film (9) outside of the area covered by the second housing part (14). (FIG. 1)
7. The control module as recited in claim 1,
the carrier (2, 2 b), as a connecting piece, is formed by the frame part (2 b) which encloses the circuit part (7), and a support part (2) which abuts the frame part outside of the housing interior (16). (FIG. 7)
8. The control module as recited in claim 1,
the stack, which is formed by the first housing part (6), the carrier (2, 2 a, 2 b), the flexible conductor film (9), and the second housing part (14), is held together by at least one fastening element (15).
9. The control module as recited in claim 8,
the stack, which is formed by the first housing part (6), the carrier (2, 2 a, 2 b), the flexible conductor film (9), and the second housing part (14), includes at least one recess, into which at least one fastening element (15) which holds the stack together is inserted.
10. The control module as recited in claim 1,
between the first housing part (6) and the second housing part (14), at least one electrical component (22) is located in a recess of the carrier (2, 2 a, 2 b) and is contacted with the flexible conductor film (9) via electrical connecting elements (23, 25). (FIG. 4)
11. The control module as recited in claim 1,
in the housing interior (16) between the first housing part (6) and the second housing part (14), at least one electrical component (26) is mounted on the conductor film (9), and is electrically contacted therewith. (FIG. 5)
12. The method for manufacturing a control module as recited in claim 1,
the first housing part (6), with the circuit part (7) mounted thereon, is manufactured as a first assembly (19) and, independently thereof, the carrier (2, 2 a) is manufactured as a second assembly (20) with the electrical components (3, 4) located thereon and with the flexible conductor film (9) located thereon, and, optionally, with the cover (18), and wherein the second assembly (20) is placed on the first assembly (19), and the electrical circuit part (7) is subsequently contacted with the flexible conductor film (9), preferably via bonding wire connections (10). (FIG. 2, FIG. 3)
after the two assemblies (19, 20) are assembled and, optionally, after a covering material (17) is placed over the circuit part (7), the second housing part (14) is placed on the flexible conductor film (9), and the first housing part, the carrier, the flexible conductor film, and the second housing part are fixed to each other using at least one fastening element (15).
