Abstract:
The wide usable interconnecting component of the present invention is capable of reducing number of components or electric elements and reducing number of interconnecting sections without limiting circuit design. The interconnecting component electrically interconnects electric components, and the interconnecting component acts as an electric element. Namely, the interconnecting component acts as a passive element or an active element.
Abstract:
The invention relates to a housing device for an electrical device (1), with at least two housing parts (2, 3) and an electronic circuit on a printed circuit board (4), which can be disposed in the device (1) and has a conductive layer that is connected to the housing mass of at least one metallic housing part (2). A housing part (3) is a plastic part into which is integrated at least the connecting device (9) for supplying power to the device and/or for transmitting signals to the electronic circuit. The printed circuit board (4) is equipped on both sides: components (5) that are sensitive to radiated interference are disposed on the side that is largely enclosed by the metallic housing part (2) and the conductive layer, and other components (6) and contacts of a connecting device (9) are disposed on the other side of the printed circuit board (4).

A package (10) has outermost surfaces (12, 13, 14, 16) that form a polygon shape. The body (11) of the package (10) has axial symmetry about an axis (21). A lead (22) exits the package along the axis (21).
Abstract:
The present invention provides a molded electric part which does not include any lead wires and is preferably compact in size and light in weight. The molded electric part of the invention can effectively prevent deterioration of an electric element by molding the element with a resin. The invention is also directed to a method of simultaneously manufacturing a number of products having fixed dimensions and excellent electrical properties through injection molding with a multi-forming mold complex. A molded film capacitor (1) of the invention includes a film capacitor element (2) and an element-receiving body (3) mainly composed of a synthetic resin with high dielectric ability. The film capacitor element (2) is accommodated in an element-receiving recess (7) formed in a substantial center of the element-receiving body (3). A couple of electrodes (2a,2a) formed on both side faces of the film capacitor element (2) are electrically connected with solder (5,5) to a film conductive pattern (4) formed by metal-plating a surface of the element-receiving body (3). Part of the conductive pattern (4) arranged on a bottom face of the element-receiving body (3) forms an outside connection terminal film (8). The film capacitor element (2) is further molded with a sealing resin (6) in an airtight manner for protecting the element-receiving recess (7) from outside humidity.
Abstract:
A space-saving circuit board mounting of a Surface Mounted Technology (SMT) device, such as a resistor, capacitor, ferrite or clock oscillator, is achieved using (1) a single through hole extending transversely through the board substrate, and (2) a cylindrical adapter having a first longitudinal portion coaxially received in the through hole and a second longitudinal portion projecting outwardly therefrom. The second longitudinal adapter portion has a radially inwardly extending notch that receives the SMT device and positions it with its electrically conductive opposite end sections spaced apart in a direction parallel to the axis of the through hole. Spaced apart external metal plating sections on the adapter connect the SMT device end portions to circumferentially separated metal plating segments on the surface of the through hole which, in turn, are representatively connected to ground and signal plane structures within the interior of the board substrate.
Abstract:
A method for installing an axial multiple connection component, for connecting to a circuit board, comprising a shell, the shell substantially cylindrical, having two opposite ends. Conducting leads extend from the opposite ends along the axis, for providing two isolated connections to other components on the circuit board. At least one contact ring encircles the shell with the axis at the center of the contact ring, and provides another connection to the other components on the circuit board. The conducting leads are inserted into lead holes on the circuit board, and the contact ring rests against a metallically plated through ring hole. The component is either manually solder utilizing a solder melting tool or alternatively wave soldered onto the circuit board, with the solder wicking up the plated through ring hole to the contact ring to make a good electrical contact therebetween.
Abstract:
A printed circuit board (23) having a plurality of solder coated contact pads (24, 26) for the surface mounting of electrical components (10.sup.1) thereon. Each pad (24, 26) has a rectangular portion and a triangular portion extending in the direction of the component's body (18) so as to reduce the amount of solder (28) located under the body (18) while not disadvantageously affecting the tolerance with which connector caps (20, 22) of the components (10.sup.1) can be mounted on, and bonded to, the pads (24, 26). This arrangement inhibits the formation of solder droplets on the printed circuit board (23) during the bonding process. At least one of the components fixed to the connector pads has an elongated electrically insulating body portion provided at its ends with connector portions which are respectively bonded to the connector pads. The dimension of the rectangular portion of each pad which is at right angles to the longitudinal axis of the associated component is less than the transverse dimension of the associated connector portion of the associated component. The connector portions of the electrical component extend over and are soldered to parts of both the rectangular and the triangular portions of each of the pads.
Abstract:
A process is disclosed for use in the manufacture of layered printed circuit board assembly having first and second layers with electrically conductive patterns thereon. The assembly has at least one inner layer between the first and second layers for receiving and retaining a surface-mount device inserted through aligned holes in the layers. The device has an electrically conductive cap at each end for electrical connection to the conductive patterns. The inner layer physically retains the surface-mount device in place pending the electrical connection of the end caps to the conductive patterns, and by virtue of its being inherently compliant and yielding, provides for physically retaining the surface-mount device in place pending the electrical and mechanical connection of the electrically conductive end caps to the conductive patterns.
