Abstract
Abstract A valve block assembly and an electronic control unit are separably joined to one another by means of a contact pin and contact sheath connection. The contact sheaths are disposed in a caplike insulating housing part of the valve block assembly. The contact sheaths are connected by flexible leads to connection contacts of the valves of the valve block assembly. This equalizes tolerances between the valves and the contact sheaths, on the one hand, and on the other thermally shields the control unit. The contact pins, anchored in the control unit, are connected to a stamped grid embedded in the control unit housing to the lead segments of which grid electronic components of the control unit are connected. These components are located on a ceramic support plate, which is joined to a heat conduction plate by adhesive bonding. The interior of the control unit housing is closed off by an outer wall serving as a protective covering.

Claim 1
Independent Claim
305 words
A mounting unit (10) including a control unit housing (72) including an interior (68), a valve bock assembly, (12) for brake pressure regulating systems, and an electronic control unit (14) separably joined to said valve block assembly, comprising: electromagnetically actuatable valves (18) disposed on the valve block assembly (12) having connection contacts (26, 28), which are indirectly joined to contact pins (62) of the control unit (14); the contact pins (62) are anchored in a housing wall (64) of the control unit (14) extending parallel to a separation plane (34) between the valve block assembly (12) and the control unit housing (72); electronic components (78) received in the control unit housing (72) of the control unit (14) on a ceramic support plate (76) are connected to a stamped grid (80) that forms lead segments (82, 84) and is embedded in the housing wall (64); the interior (68) of the control unit housing (72) is closed, on a side remote from the separation plate (32), by an outer wall (70) placed upon it; the valve block assembly (12) is provided with a caplike insulating housing part (30), which with a wall (32) extending parallel to the separation plane (34) fits over the valves (18); contact sheaths (56) which cooperates with the contact pins (62) of the control unit (14) are received in the wall 32 of the housing part (30); the connection contacts (26, 28) of the valves (18)are indirectly joined to the contact sheaths (56) by flexible leads (48, 58); the ceramic support plate (76) for the electronic components (78) is disposed indirectly on the side of said housing wall (64) of the control unit (14) remote from the separation plane (34); and the outer wall (70) of the control unit housing (72) embodies a protective covering for the interior (68) of the control unit.
