Abstract
An ejector for ejecting a riser card detachably connected to a backplane board, said ejector comprising an elongated ejector lever comprising a first end for rotatable attachment to said riser card and a second end for ejecting said riser card by inducing rotation of said ejector lever about a pivot section disposed between said first and second ends of said ejector lever, and an elongated support post comprising a first end for contacting said backplane board and a second end for rotatably supporting said ejector lever at said pivot section of said ejector lever.
Claims19
An ejector for ejecting a riser card detachably connected to a backplane board, said ejector comprising:
- an elongate ejector lever comprising a first end for rotatable attachment to said riser card and a second end for ejecting said riser card by inducing rotation of said ejector lever about a pivot section disposed between said first and second ends of said ejector lever;
- and
- an elongate support post comprising a first end for contacting said backplane board and a second end for rotatably supporting said ejector lever at said pivot section of said ejector lever.
An ejector for ejecting a riser card detachably connected to a backplane board, said ejector comprising:
- an elongate ejector lever comprising a first end for rotatable attachment to said riser card and a second end for ejecting said riser card by inducing rotation of said ejector lever about a pivot section disposed between said first and second ends of said ejector lever, said pivot section of said ejector lever comprises a rotation pin for providing a point of rotation of said ejector lever;
- and
- an elongate support post comprising a first end for contacting said backplane board and a second end rotatably supporting said ejector lever at said pivot section of said ejector lever wherein said second end comprises a retainer for securing said pivot section of said ejector lever during rotation.
A system for facilitating the use of printed circuit boards in electronic devices, said system comprising:
- a backplane board;
- a riser card detachably connected to said backplane board;
- an elongate ejector lever comprising a first end attached to said riser card and a second end for ejecting said riser card by inducing rotation of said ejector lever about a pivot section disposed between said first and second ends of said ejector lever;
- and
- an elongate support post comprising a first end in contact with said backplane board and a second end rotatably supporting said ejector lever at said pivot section of said ejector lever.
A method for separating a backplane board from a detachable riser card, said method comprising the following steps:
- forming an elongated lever comprising a first end, a second end and a pivot section between said first and second ends;
- forming an elongated post having first and second ends;
- rotatably affixing said first end of said lever to said riser card;
- positioning said post so that said first end of said post contacts the backplane board and said second end of said post rotatably supports the pivot section of said lever;
- applying force to the second end of said lever so that said lever rotates about said pivot section, said first end of said lever applies ejection force to said riser card, and said riser card separates from said backplane board.
