Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
56 words
A printed circuit arrangement comprising a frame a plurality of flexible, thermally conductive webs secured at their respective ends to the frame, and a printed circuit board secured to said webs so that each web has adjacent each end thereof a free length extending between the frame and an adjacent edge of the printed circuit board.
Claim 2
Dependent Claim
56 words
A printed circuit arrangement comprising a frame a plurality of flexible, thermally conductive webs secured at their respective ends to the frame, and a printed circuit board secured to said webs so that each web has adjacent each end thereof a free length extending between the frame and an adjacent edge of the printed circuit board.
Claim 3
Dependent Claim
26 words
An arrangement as claimed in claim 1 in which said frame comprises a two frame members to which said ends of said webs are respectively secured.
Claim 4
Dependent Claim
18 words
An arrangement as claimed in claim 1 in which said webs are arranged in spaced, substantially parallel ralationship.
Claim 5
Dependent Claim
30 words
An arrangement as claimed in claim 3 which includes a rigid strip between an adjacent pair of said webs, the ends of said strip being secured to said frame members.
Claim 6
Dependent Claim
25 words
An arrangement as claimed in claim 3 in each said frame member comprises a pair of frame elements between which said web ends are secured.
Claim 7
Dependent Claim
27 words
An arrangement as claimed in claim 5 in which one frame element in each pair thereof is formed with slots to receive the ends of said webs.
Claim 8
Dependent Claim
53 words
An arrangement as claimed in claim 2 in which said frame members include projections which overlap said printed circuit board, and which includes resilient buffers mounted on said projections so as to be engageable by said board to limit movement thereof in its own plane transversely of the lone axes of said webs.
Claim 9
Dependent Claim
21 words
An arrangement as claimed in claim 1 which includes two printed circuit boards secured to said webs on opposite sides thereof.
Claim 10
Dependent Claim
57 words
An arrangement as claimed in claim 8 which includes a further printed circuit board secured between said two boards and projecting beyond adjacent edges thereof, said further board being electrically connected to at least one of said two boards and including on its projecting portion a conductor pattern which serves as a plug connection for the arrangement.
Claim 11
Dependent Claim
24 words
An arrangement as claimed in claim 1 in which said printed circuit boards comprises a ceramic card and a conductor pattern on said card.
Claim 12
Dependent Claim
16 words
An arrangement as claimed in claim 1 in which said webs are formed of braided copper.
