摘要:
The housing for an electronic circuit is box-shaped, and on each of its longitudinal sides in its interior has a shoulder (44, 45), and above each of those a ridge (47, 48) and -- extending along a longitudinal side. A cooling frame (11) is pushed into the grooves (52, 53) formed between shoulder and ridge, with a printed circuit board (10) being fixed to the underside of the cooling frame. In its interior, the cooling frame has cooling tabs (15, 16, 17) which stand perpendicular to the surface of the printed circuit board and on which power components (20) are fixed.
摘要:
The electrical unit has a printed circuit board (10) supporting the circuit, which includes a power component (11) which generates heat. In order to dissipate this heat from the power component, the power component rests on a heat conductive layer (13) which in turn is applied to the upper side (12) of the printed circuit board. This heat conductive layer further has a portion of the lid (18, 19) 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 (13) to the cooling element (18, 19) so that the latter may be applied and formed independently of type and form of the power component.

The housing for an electronic circuit provided with a connection plug, particularly for control device electronics of an internal combustion engine of a vehicle, includes a cooling frame to which a printed circuit board having the electronic circuit is fastened and which has at least one cooling portion with which power components connected to the printed circuit board are connected so as to conduct heat, and also includes a cover enclosing the printed circuit board. For a simple construction, it is suggested that the cooling frame (5) be constructed as a flat frame (6) with flat frame legs (8, 8a, 8b, 8c, 8d) substantially parallel to the plane (7) of the printed circuit board (3), the housing cover pieces (12, 13) forming the cover (11) being arranged at the upper and lower sides (9, 10) of the flat frame (6).

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.
摘要:
The holder (1) for an electronic component (20), especially a hybrid module, is preferably a unitary plastic element having an elongated base plate (2) formed with openings (14) therein to permit insertion of terminal pins or lugs (21) projecting from the component therethrough. Two holder arms (30) project from the base plate, the holder arms having module support portions (3) and oppositely projecting posts (4). The posts fit into receiving openings (26, 27) of a printed circuit board, which receiving openings having a spacing (S) which is greater than the distance (D) between the posts so that, upon insertion of the posts in the openings the arms (30) will tilt towards each other, thus clamping a module, typically in card or board form, between the module support (3) of the arms. The holder can also form a transport holder for the module, by forming, for example, in the module a notch spaced from the upper edge, and engaging the notch (22) with a projecting rim (9) formed on the upper ends of the support portions (3) of the arms, the notch being so spaced that the terminal lugs or pins (21) then just fit into the openings (14) in the base plate, thereby protecting the pins against damage.
摘要:
To provide for simplified and less expensive manufacture without extensive insulation of internal components of a control system with respect to the housing, particularly for electronic ignition and fuel injection control systems, digital and other automotive control electronic systems and the like, a housing (1) of insulating plastic material has a connecting portion (2, 3) integrally formed therewith, which further include, integrally formed therewith, holding and engagement catches and slits (13, 15, 17-23; 62, 69) for a printed circuit board (41) carrying electronic network elements (42) such as transistors, capacitors, resistors, in integrated circuit form, or as discrete elements; and further a cooling device (24, 25; 56; 64; 73) in heat-conductive relationship to a power stage (43; 54; 65; 74) to dissipate heat generated within the power stage, and to transfer the heat over a large area surface connection either to a structural component carrying the entire control unit and/or to a sheet metal cover (49) snapped and crimped over the plastic housing (1) and, in sealed relation, closing off the entire structural unit.
摘要:
A housing (1) for and electrical device having at least two housing parts (2) and an electrical circuit on a printed-circuit board (5) that can be attached in the housing (1) are proposed. Furthermore, a connection device for the power supply of the device and/or signal transmission to the electronic circuit that is capable of being attached to the housing (1) is provided. After the housing parts (2) are joined, one housing wall (4) that is integral with one of the housing parts (2) forms an interference radiation-proof, chamber-like recess (3) for accommodating the connection device. Furthermore, at least one electrically-conductive contact conductor tracks of the printed-circuit board (6) connected with a ground connection of the housing.
摘要:
Short extensions (15) are formed on the housing (10) of a control device. These extensions (15) consist of the same material as the housing (10) and can therefore be produced in a simple and cost-effective manner in a single production process. The impact energy being created when the housing (10) is dropped on the ground can be compensated with the aid of these extensions (15). In special cases and as a function of the specifications, visually noticeable damage of the extensions (15) can be used as an indicator for possible damage to the electric components arranged in the housing (10).

The invention relates to a pin (10) which can be electrically connected in a soldering-free manner to a printed circuit board, said pin comprising a punching sheet profile provided with a contact pin section (11) for a plug connector and/or a plug connector strip, a first securing section (12) for the plug connector and/or the plug connector strip, a connection section (13) and a second securing section (15) provided with a pressing-in area (16), which can be at least elastically shaped in a printed circuit board hole such that it can be adapted to the diameter of the hole. The pin (10) comprises a bearing profile (14, 18, 19) which is arranged in the punching plane and which is used for a pressing-in tool (24) and is angled away from the punching plane in a connecting section (13) thereof. An insertable and removable, after having been inserted, pressing-in tool is provided for the insertion of at least one pin
摘要:
A method for the attachment of electrical components to circuit boards where the electrical components are enclosed by a housing and held in place by a retaining device. The method enables a smaller and more compact construction for switching devices. The connection of the electrical components with the housing enclosing them creates a additional point for the absorption of thermal and mechanical stresses in addition to the connection with the circuit board.
