Abstract:
A busbar holder includes a supporting base having engaging prongs located at opposing ends of the supporting base. These engaging prongs engage receptacles in a printed circuit board (PCB) to secure the supporting base to the PCB. Four securing prongs extending vertically upward and having catch hooks at their free end are attached to the respective corners of the supporting base. A supporting wall extending vertically upward is attached to the supporting base and located intermediate the four securing prongs. Busbars are inserted between the wall and two of the securing prongs and are secured in place by the catch hooks.
Abstract:
A mother board assembly includes a mother board which has a top face and a first connector mounted on the top face. A first mounting seat is mounted on the top face on one side of the first connector and includes at least one resilient first positioning member which is substantially C-shaped. The first positioning member defines a first groove and has two spaced free ends. A second mounting seat is mounted on the top face on the other side of the first connector and includes at least one second positioning member which has a substantially U-shaped retaining portion that defines a second groove. A curved plate portion extends from the retaining portion in a direction away from the first mounting seat. An interface card has a front end, a rear end, a bottom face and a second connector mounted on the bottom face between the front and rear ends.
Abstract:
A package for enclosing and mounting a multichip module in which separate mechanisms are provided for mechanically attaching the package to a circuit board and for electrically connecting the package to the circuit board to which it is attached. The package includes a ceramic base on which the multichip module is supported, a frame-like retaining ring which enables the attachment of the package to the circuit board and a lid for covering the top of the package and sealing it off from environmental influences. The package also includes a set of electrical leads extending from the interior to the exterior of the package for providing multiple separate connections between the multichip module and the circuit board on which it is mounted.
Abstract:
A method and apparatus for mounting daughter boards onto a printed circuit mother board. Daughter boards are mounted on the mother board using a new spacer. This spacer comprises: an electrically insulated body; one or more pins protruding from one end of the body which fit into the circuit component holes of the mother board; and a hole at the other end of the body which accepts a fastening device inserted through a hole in a daughter board, that attaches a daughter board to the mother board. Advantageously, a minimum amount of space is used on the mother board, and the daughter boards can be mounted wherever convenient.
Abstract:
A lead wire holder including a first holding member and a second holding member. The first and second holding members are interconnected so that both can be folded and put together through a connecting portion. The holding members are provided on the inside thereof with opposed lead wire insertion recesses mounting legs for mounting the holder to a printed circuit board project downwardly from the lower end surface of either or both of the holding members. Elastic tongue portions for elastically holding lead wire are formed from a part of the wall portions of the lead wire insertion recesses. Narrow recesses are disposed on the lower end surface and extend from the insertion recesses, so that the insertion end of each lead wire is restricted when its coated end abuts against with the narrow portions. It is thereby possible to let downwardly projecting cores of the lead wires have a uniform projecting length.
Abstract:
A power supply packaging arrangement which utilizes transformer as the main structural component. Side panels of the package are connected to the transformer. These panels support the transformer, additional power supply circuitry and the top, front and rear sides of the package.
Abstract:
An anchoring device for securing a capacitor body to a printed circuit board provides a circumferential band for encircling the capacitor body, the band including a crimpable section for reducing the circumference of the band and for applying compression to the band to engage the capacitor body, and a plurality of connectors affixed to the band and extending perpendicular to the circumference thereof for penetrating the printed circuit board to allow mounting of the clamp and thereby the capacitor body to the printed circuit board.
Abstract:
An electro-mechanical package is disclosed which includes an LCD and an IC chip mounted on opposite sides of a PC board by common package-retaining means, which includes posts extending through the PC board and a clip member that latches onto the ends of the posts to retain the package in assembled position. The latching action is resilient and permits non-destructive disassembly.
Abstract:
A substrate carrying electrical circuit patterns and elements is supported in an upright position on a printed circuit board by a clip so as to restrict rotational movement of the substrate from that position when pins and plated through holes on the substrate and board are engaged. The clip comprises a body having a flat bottom for contacting one side of the board and a first-cylindrical peg depending from the bottom. Spaced-apart sections on one side of the body are in a common plane perpendicular to the bottom with a protrusion near the top of the body extending beyond this plane. A second-rectangular peg also extends from the one side of the body past the common plane, with the base of the second peg being in line with the flat bottom. A trough in the protrusion receives one edge of the substrate, with one side of the latter contacting the side sections in the common plane, and the opposing edge of the substrate being proximate the bottom of the body. When the pins are engaged in the plated through holes, the first peg makes a slip fit in a hole in the board to restrict rotational movement of the substrate.
