Abstract:
An electrical interface device for washing and drying machines and the like, has at least one rigid planar element, to which there are firmly applied one or more flexible printed circuits, electrically connected to one another and to the electromechanical and/or electronic programming component of the machine. The edges of the rigid planar element and of the flexible printed circuits are provided with alternating slots and teeth. To the teeth there are applied the terminals of the electrical paths of the circuits, forming in this manner zones adapted for the insertion of electrical connectors of low and high power.
Abstract:
A connecting terminal for connecting an electronic component to a printed circuit board includes a rectangular metal plate and a leg provided at each of four corners thereof. The approximate center of the metal plate is provided with a screw hole through which a screw is passed that is screwed into a terminal of a screw terminal-type electronic component. The legs of the connecting terminal, which are passed through pin holes provided in the printed circuit board, are soldered to an electrical circuit and thereby fixed to the circuit board. A screw which is screwed into the terminal of the screw terminal-type electronic component is passed through the screw hole of the connecting terminal. When the screw is tightened, the electronic component is secured to the printed circuit board.
Abstract:
A connector for providing mechanical support and electrical contact between two printed circuit boards, or between an electrical component and a printed circuit board includes a base, two contact members, and a guide tip. A plurality of the connectors may be aligned by one or more removable tabs until assembly or encapsulation.
Abstract:
A welding method and means is disclosed utilizing a conductive foil disposed between or adjacent members to be welded together with the foil serving as one electrode and one or both of the members serving as another electrode of the welding circuit and with the members being forced together or with the foil being forced against the members by a separate electrode.
Abstract:
A feed-thru device making it possible to stack integrated circuits and/or printed circuit boards in closely spaced parallel fashion and providing means for joining components and/or terminals from one adjacent board to the next. The feed-thru is comprised of a solid conductive body for threadedly engaging suitable mounting hardware to rigidly join adjacent boards in closely spaced parallel fashion. The conductive body further acts as part of a coaxial circuit in conjunction with a center conductor electrically isolated from he conductive body by a suitable insulating sleeve, which center conductor further functions as a pin or terminal for connection with the printed circuit terminal element at both ends of the center conductor or pin. The configuration of the pin provides excellent impedance matching between each printed circuit through the coaxial configuration. The mounting hardware is so arranged as to provide excellent mode suppression at microwave frequencies.
Abstract:
A plurality of electrical leads retained in spaced parallel relation and passing through apertured guide blocks disposed at both ends of the leads. The conductor portions of the leads extend through the apertures for connection at one end to terminal lugs on a transformer housing. The opposite ends of the leads are stripped to permit the connection thereof to a circuit board.
