Abstract
A power supply assembly includes a dielectric substrate and a power supply circuit supported by the dielectric substrate. A conductive connection block is attached to the dielectric substrate at a main surface thereof and is connected to a power supply terminal of the power supply circuit. A spring probe pin is fitted in a bore formed in the connection block and includes a conductive sleeve and a conductive plunger fitted in the sleeve. The conductive sleeve is in electrically conductive contact with the connection block.
Claims25
A power supply assembly comprising:
- a dielectric substrate having first and second opposite main surfaces,
- a power supply circuit supported by the dielectric substrate and having first and second power supply terminals,
- a first conductive connection block attached to the dielectric substrate at the first main surface thereof and connected to the first power supply terminal of the power supply circuit, the first connection block being formed with a bore, and
- a spring probe pin fitted in the bore formed in the connection block,
- and wherein the spring probe pin includes a conductive sleeve and a conductive plunger fitted in the sleeve and the conductive sleeve is in electrically conductive contact with the first connection block.
A power supply assembly comprising:
- a dielectric substrate having first and second opposite main surfaces,
- a power supply circuit supported by the dielectric substrate and having first and second power supply terminals,
- first and second conductive connection blocks attached to the dielectric substrate at the first and second main surfaces respectively and connected to the first and second power supply terminals respectively of the power supply circuit, the first and second connection blocks being formed with respective arrays of bores,
- a first plurality of spring probe pins fitted in the bores in the first connection block, and
- a second plurality of spring probe pins fitted in the bores in the second connection block.
A power supply assembly comprising:
- a card having first and second opposite sides that are joined by a peripheral edge of the board, the card including an insulating substrate and having first and second conductive layers,
- at least one power module having first and second terminals connected to the first and second layers respectively of the card, and
- first and second connection blocks attached to the card at the first and second sides respectively and each including a first portion in contact with the card and a second portion that projects beyond said peripheral edge of the card whereby said second portions of the respective connection blocks are in mutually spaced confronting relationship,
- and wherein at least one of the connection blocks is configured so that said second portions are substantially closer together than are said first portions.
