Abstract:
In a vehicle electronic control unit, a power device (21) and a circuit component (22-25), which structure a circuit in which current flows when the power device (21) is driven, and a printed board (31) are disposed within an aluminum case (30) as a housing. Both the power device (21) and the circuit component (22-25) are disposed within a resin mold unit (40) in a state where both the power device (21) and the circuit component (22-25) are wired so that a loop circuit is structured as a current path. Both the power device (21) and the circuit component (22-25) are mounted on the printed board (31) by using a connection terminal (41) which protrude from the resin mold unit (40). According to the vehicle electronic control unit, noise and efficiency of the circuit can be improved because a loop of large current can be reduced.
Abstract:
Zur Kontaktierung von verschiedenen Leiterplatten innerhalb eines Gehäuses werden meistens Stecker, korrespondierende Aufnehmer und gegebenenfalls dazwischen liegende Verbindungsleitungen verwendet, die teuer sind und zusätzliche Arbeitsschritte bei der Montage erfordern. Als Lösung der technischen Aufgabe wird eine Anordnung beschrieben, bei der auf den Leiterplatten (4,5) erste Kontaktmittel (7) und im Gehäuse (1) eine Kontaktierungsbrücke (10) mit zweiten Kontaktmitteln (14) angeordnet sind, wobei beide Kontaktmittel miteinander korrespondieren. Bei der Montage werden die Leiterplatten (4,5) mit den ersten Kontaktmitteln (7) einfach auf die Kontaktierungsbrücke (10) gelegt, wodurch ein Kontakt zwischen den verschiedenen Leiterplatten (4,5) hergestellt ist.
Abstract:
Zum Herstellen elektrisch leitender Verbindungen zwischen flachen Leiterbahnen (3, 4), die durch einen Isolierträger voneinander getrennt sind, werden zwei Metallfolien (1, 2), die mit Heißkleberschichten (5, 6) beschichtet sind, nebeneinandergelegt. An den Stellen der später herzustellenden und miteinander zu verbindenden Leiterbahnen (3, 4) sind Kontaktpunkte (7, 10) vorgesehen, an welche Drähte (8, 9, 10) angeschweißt werden, die, soweit sie auf der Ebene der Metallfolien (1, 2) verlaufen, durch Wärmezufuhr in die Schichten (5, 6) eingebettet werden. Anschließend werden die Metallfolien (1, 2) mit ihren Heißkleberschichten (5, 6) unter Zwischenlage des Isolierträgers gegeneinandergeklappt und durch Wärmezufuhr mit diesem verbunden. Nunmehr werden von den Metallfolien (1, 2) die Zwischenräume (13, 14) zur Bildung der Leiterbahnen (3, 4) abgeätzt.
Abstract:
An electronic module. The electronic module includes a circuit carrier having an electrical and/or electronic circuit. This circuit is completely embedded in an encapsulation molding compound. The electronic module includes an electrically contactable outer contact connection arranged on the enclosure, which has a press-fit zone. The contact connection is electrically connected to the electrical and/or electronic circuit on an upper side of the circuit carrier facing the press-fit zone. In the region of the press-in zone, the contact connection in the enclosure is free of the encapsulating compound. The contact connection is accommodated in a cavity of a holding frame made of a plastics material. The cavity is formed by a closed wall running around the contact connection, which rests on the upper side of the circuit carrier and projects in a direction of the press-fit zone. The wall separates the cavity from the encapsulating compound.
Abstract:
A base member that is a molded part on which pattern wiring is directly formed, includes a projection projecting from a base surface of the base member. The pattern wiring is laid over a top of the projection, and protrusions are molded on both sides of an area at the top of the projection where the pattern wiring passes.
Abstract:
A display apparatus in which a height of an AC socket protruding to a rear side of a printed circuit board is reduced and a power cord is provided to be in close contact with a product to provide a display apparatus in which a creeping distance is increased to prevent the printed circuit board from being damaged by a high voltage or a stroke of lightning.
Abstract:
A signal transmission system including: a first connector apparatus, and a second connector apparatus that is coupled with the first connector apparatus. The first connector apparatus and the second connector apparatus are coupled together to form an electromagnetic field coupling unit, and a transmission object signal is converted into a radio signal, which is then transmitted through the electromagnetic field coupling unit, between the first connector apparatus and the second connector apparatus.
