Abstract:
Die Erfindung betrifft ein Anschlusselement zur elektrischen Anbindung einer LED, die auf einer Platine angeordnet ist, welche zur Kontaktierung mit elektrischen Leitern Kontaktfelder aufweist, wobei das Anschlusselement Kontakte aufweist, welche einerseits mit Anschlusskabeln und andererseits mit den Kontaktfeldern verbindbar sind und mit einer die LED überfangenden, lichtdurchlässigen Abdeckung. Aufgabe der vorliegenden Erfindung ist es, ein Anschlusselement zur elektrischen Anbindung einer LED bereitzustellen, welches hinsichtlich seines elektrischen Anschlusses und seinem Aufbau kostengünstig und mit geringem Aufwand hergestellt und montiert werden kann. Gelöst wird die Aufgabe durch ein Anschlusselement mit den Merkmalen des Anspruchs 1, insbesondere dessen kennzeichnenden Merkmalen, wonach die Abdeckung, in welche die Kontakte integriert sind, das Anschlusselement bildet.
Abstract:
Methods and means for embedding electronic components, such as LED-based light sources and associated control circuitry, into molded or continuously cast surface materials (e.g., material manufactured under the trademark CORIAN®). During the manufacture of the surface material, the components can be held in position using a scaffold or frame constructed of a sacrificial material, the same material as the finished surface material and/or another material used in the manufacture of the finished product. The embedded components can include control circuitry, e.g., printed circuit boards, for separately controlling each component, power conductors and data busses. Conductors and/or busses can be in the form of conductive rails, wire mesh or sheets. Access to the conductors in the finished product can be made by a number of methods, including but not limited to sanding, grinding, drilling into, screwing into, and/or inserting pins into the finished material.
Abstract:
A method for providing a mechanical/electrical interconnection between two circuit boards, and the interconnection components required therefore, include a pin and socket each having a tail portion, a shoulder portion and a head portion. The tail portion of the pin is sized so as to fit into a plated through hole of the first board, the head portion is sized so as to allow an automated device to capture the head portion and to rest on top of the plated through hole when inserted therein, and the shoulder portion is sized in relation to the plated through hole so as to rest inside the plated through hole and to allow a predetermined amount of solder to flow under the head portion and down into the plated through hole, but not as far down as the tail portion, thereby assisting in centering the pin in the through hole. Upon heating to a solder reflow temperature, a ring of solder, around the periphery of the head portion of the pin and the shoulder portion of the socket, flows under the head of the pin and the shoulder of the socket, thereby forming a soldered electrical connection between the pin and the first board, and the socket and the second board. By aligning the pin with the socket and inserting the tail portion of the pin into the cavity of the socket, a separable reliable mechanical and electrical interconnection is formed between the first board and the second board.
Abstract:
Materials which are used for detachable injection moulded parts can be applied for making fast, solid and reliable connections, particularly by using easily degradable respectively soluble polymers. The materials can be adapted to other conditions, such as the prevention of chemical influencing or other kind of poisoning, the degree of electrical insulation, etc.
Abstract:
A printed circuit board assembly (200) for coupling a plurality of surge protectors (10) to multi-line communication cables (52) includes a multi-layer printed circuit board (130), to which has been mounted at least two cable connectors (220), having multiple female sockets (210) for receiving standard surge protector modules (10). The multi-layer printed circuit board (130) includes traces (350) on multiple layers in a manner that a unique circuit path exists between each lead in each connector and a predetermined one of the plurality of sockets for receiving surge protector modules. The traces having a width and a copper content sufficient to carry large current surges from induced power signals, by way of example, from a lightning strike, without breaking down.
Abstract:
A method for providing pre-placed, pre-brazed feed throughs in the substrate (4) of a hermetic package corresponding to the terminal leads (6b) of the encased circuit COTS components (6). The substrate (4) may include directly bonded copper (DBC) regions forming circular shapes (10) where the holes for the special connectors of the present invention will be located. These holes will correspond to the leads of the circuit component (6) that will be mounted to it. Holes are laser or mechanically drilled into the substrate (4) inside the circular shapes (10) formed in the DBC. To form the feed through, a bushing (12), such as a blind copper rivet, is brazed in the hole, with the open end thereof oriented toward the component-side of the substrate. These open ends can accept the leads of the circuit component (6), like the holes of a conventional PC circuit board.
