The electrical unit has a printed circuit board (,) supporting the circuit, which includes a power component (,) which generates heat. In order to dissipate this heat from the power component, the power component rests on a heat conductive layer (,) which in turn is applied to the upper side (,) of the printed circuit board. This heat conductive layer further has a portion of the lid (,) of the housing resting on it, which serves as a cooling area. Alternatively, the cooling area can be a free-standing cooling element. The heat transfer thus takes place via the heat conductive layer (,) to the cooling element (,) so that the latter may be applied and formed independently of type and form of the power component.

In order to provide protection against disruptive radiation and achieve good conduction of heat, a housing for control devices which has multiple parts is provided with a printed circuit board carrying power components and control elements with a peripherally extending lining of electrically and thermally conducting material. The printed circuit board is clamped between the housing halves in the region of the linings. The power components are contacted by the lining so as to be thermally conducting, while control elements which give off intensive disruptive radiation or are sensitive to such radiation are enclosed within connecting pieces projecting from the walls of the housing parts.

Housing for an electronic circuit

A housing for an electronic circuit, especially for a control electronic device of a motor vehicle, has a printed circuit board adapted to carry an electronic circuit, a plug strip, a front plate, a cooling frame mounted on the board and having at least one cooling portion, power elements connected with the cooling portion in a heat conductive manner. The front plate is provided with cooling ribs and the cooling frame is provided with at least one cooling leg facing toward the plug strip so that the plug strip is located between the front plate with the cooling ribs and the cooling leg of the cooling frame. The front plate and the cooling frame are connected through a heat conducting web on the front plate in a heat conducting manner.

Housing for electronic circuit

An electrical connector combination thoroughly sealed against moisture and dirt and resistant to temperature variations and shaking forces consists of a male connector (1) equipped with connector prongs (3) set in a casing (2) and a female connector (10) having corresponding sockets (12) disposed in a casing (13) in which a compressible seal plug (22) is set which surrounds the conductors which are electrically and mechanically affixed to the connector sockets (12). The seal plug 12 is compressed by an assembly of rigid parts including the casing plug (13), a metallic washer (25) and a cap nut (27), the last of which can be screwed tight with a certain torque to clamp the assembly. A sealing effect is exerted on the conductors (11) and the casing plug (13) in a radial direction without exposing the seal plug (22) to rotary movement. A seal ring (9) is seated on a forward section (15) of the socket casing plug (13) extending into the male connector casing (2). This seal ring seals the joint of the connector parts with the help of a connection sleeve acting through a bayonnet lock, without the seal ring being able to yield radially.
