Abstract:
A capacitor holder comprising a body part formed in a shape into which a tip end of a capacitor can be fitted; and a lead part which is fixed to the body part and can be soldered to a predetermined fitting location. The body part has an opening through which the tip end of the capacitor is exposed, and an end surface abutment portion which abuts a tip end surface of the capacitor in a vicinity of a pressure valve, when the tip end of the capacitor is fitted into the body part. The lead part is fixed to the body part at a position opposite to the capacitor with respect to a reference plane, which is a plane includes the tip end surface of the capacitor abutting the end surface abutment portion.
Abstract:
A lead component holder includes a plurality of supporting portions each supporting a lead component at a position distant from a component mounting surface of a substrate, and at least one coupling member coupling the adjacent supporting portions at a position distant from the component mounting surface. An electronic device includes the substrate, the lead component holder, and an electronic component mounted to the substrate located below the coupling member.
Abstract:
An aluminum electrolytic capacitor includes a main body, two electric leads, and a metal set plate. The main body has a base and a plastic insulating film. The electric leads are located at one end of the base. The metal set plate is located at opposite end, with a connecting portion and a soldering portion. The connecting portion is located at the surface of the other end of the base opposite of the two electric leads. The soldering portion extends outside of the main body. The plastic insulating film wraps around the main body and the outer edge of the connecting portion. Thereby, the metal set plate is secured firmly with the main body. The soldering portion of the metal set plate is soldered onto the printed circuit board, allowing the aluminum electrolytic capacitor to be firmly attached to the printed circuit board.
Abstract:
A surge protector includes a body having an outer surface, and a clamp snapped on the body. The clamp includes spring clips. The spring clips have at least two support areas that are in a substantially same plane. The surge protector may also include a center electrode and terminal electrodes on ends of the body.
Abstract:
A mounting member has a tube, and a plurality of clamps. The clamps hold the tube or outer portions on both sides of the tube. Therefore, the external load on the mounted part can be minimized while at the same time the mounted part is easily held fixedly on a board such as a printed wiring board.
Abstract:
A press fit passive component, such as a resistor or capacitor, adapted to fit within, or partially within, a via of a printed circuit board. In one example, the press fit passive component has a cylindrically shaped body with solderable terminals at either end of the body, and a dielectric collar disposed at least partially about the cylindrically shaped body.
Abstract:
An electronic assembly having a large or massive electronic component mounted to a circuit substrate is stabilized against movement due to shock and/or vibration by an elastic dampening member disposed between the large electronic component and a clamping member that compresses the dampening member between the clamping member and the electronic component and urges opposite end walls of the dampening member against opposite sidewalls of the electronic component to securely grip the electronic component between the opposite end walls of the dampening member. The arrangement is effective for reducing and/or eliminating damage and subsequent failure due to exposure of the electronic assembly to shock and/or vibration.
Abstract:
A printed circuit board and method for reducing the impedance within the reference path and/or saving space within the printed circuit board. In one embodiment of the present invention, a printed circuit board comprises a plurality of conductive layers. The printed circuit board further comprises two or more vias for interconnecting two or more conductive layers. The printed circuit board further comprises an electrical component embedded in a particular via between two conductive layers to reduce the impedance within the reference path and/or save space within the printed circuit board.
Abstract:
To provide a mounting substrate that requires a reduced amount of solder and reduces a thermal effect of solder on the interior of an electronic component, and a microphone to be mounted on the substrate. A mounting substrate according to the present invention includes: a solder part formed on a part of an electrode formed on the mounting substrate; a resist film formed to prevent the solder of the solder part from flowing out of a predetermined range; and a gas-escape groove that is constituted by the absence of the electrode and the resist film and allows gas produced during soldering to escape. In the case where a component having a central terminal and a peripheral terminal is mounted on the mounting substrate, each part of the mounting substrate has the characteristics described below. That is, the electrode formed on the mounting substrate includes a central electrode part that faces the central terminal, a plurality of outer electrode parts that face part of the peripheral terminal, and a linkage electrode part that interconnects the outer electrode parts. The solder part is formed on each of the central electrode part and the outer electrode parts. The gas-escape groove is configured to allow the gas inside the peripheral terminal to escape to the outside.
