Field-replaceable printed circuit board cable assembly and method of use
View Patent ↗A field-replaceable printed circuit board (“PCB”) cable assembly comprises at least one field-replaceable PCB, at least one cable, a connector with a plurality of beams, and top and bottom hood portions. A first end of the at least one field-replaceable PCB is attached to the at least one cable, and a second end of the at least one field-replaceable PCB is attached to the plurality of beams. The at least one field-replaceable PCB can be replaced by disassembling the hood portions, detaching the at least one field-replaceable PCB from the plurality of beams, and attaching at least one new field-replaceable PCB.
1. A cable assembly comprising:
at least one cable having wire conductors;
at least one printed circuit board having a first end and a second end, the printed circuit board further having offset notches therein;
a first plurality of pads attached to said first end of said printed circuit board;
a second plurality of pads attached to said second end of said printed circuit board;
a connector having a plurality of beams;
a housing having a top hood portion and a bottom hood portion, the top hood portion having fastener holes therein that align with fastener holes in the bottom hood portion when the housing is assembled; and
fastener members configured to be disposed within the fastener holes of the top and bottom portions to fasten the top hood portion to the bottom portion when the housing is assembled, the fastener members also configured to be disposed within the offset notches of the printed circuit board to secure the printed circuit board within the housing when the housing is assembled;
wherein said wire conductors of said cable are attached to said second plurality of pads on said second end of said printed circuit board, and wherein said beams of said connector are separably attachable to said first plurality of pads on said first end of said printed circuit board; and
wherein said hood portions are separably attached and can be separated so as to allow for the removal and replacement of said printed circuit board.
2. The cable assembly of claim 1 wherein the cable assembly comprises two printed circuit boards.
3. The cable assembly of claim 1 wherein the beams are cantilever beams.
4. A method of removing and replacing a printed circuit board in a cable assembly having at least one printed circuit board, a connector with a plurality of beams, and a housing having a top hood portion and a bottom hood portion, wherein the at least one printed circuit board is separably attached to said plurality of beams, comprising the steps of:
disengaging fastener members from fastener holes in the top and the bottom portions of the housing and from offset notches in the at least one printed circuit board;
separating said top hood portion from said bottom hood portion;
detaching said at least one printed circuit board from said plurality of beams;
providing at least one new printed circuit board;
attaching said at least one new printed circuit board to said plurality of beams;
attaching said top hood portion to said bottom hood portion; and
reengaging the fastener members within the fastener holes in the top and the bottom portions of the housing and within the offset notches in the at least one printed circuit board.
