Title: Clamping arrangement for electronic modules
Inventor: RUSH DEREK ANTHONY
IPC: F16B29/00
Filed: 1985-07-30
Abstract: Heat dissipation from electronic modules 20 is improved by clamping their edges against heat- conducting fins in a housing 2 by means of two expanding jackscrews 40. Each jackscrew 40 has a shaft 41 mounted in bearings 45 and 46 in the module 20 and carries a row of alternate closed rings 50 and split rings 51. The closed rings 50 are smaller in diameter than the split rings 51 and have a circular section. The split rings 51 are of tubular shape, having ends of circular section which engage the closed rings. The forward end of the shah 41 is screw-threaded to engage a fixed nut 44 in the housing 2. When the shaft 41 is screwed into the fixed nut 44 it pulls a connector 30 on the module 20 into engagement with a cooperating connector in the housing. At the same time, the closed rings 50 are forced against the split rings 51 causing them to expand radially and exerting a clamping force against the edges of the modules forcing them into thermal contact with the fins 5 on the housing 2. <IMAGE>
