Abstract
A removable sensor assembly (10) comprises a removable sensor member (15) to be inserted into the opening (27) of an insulated housing (13) mounted on the surface of a PCB (11) and secured thereon by a pair of the contact members (16, 17). The contact members (16, 17) have respective foot portions (19, 20) which are soldered to contact pads (14) on the PCB (11). The removable sensor member (15) is a piezoelectric film sensor mounted onto a hard drive to detect physical shock and to shut the drive down in order to prevent destruction of data thereon. The opening (27) is a slot angled at 45.degree. to the surface of the PCB (11) to allow a three- axis sensing capability as well as reducing the overall height of the insulated housing (13). Each of the contact members (16, 17) includes a contact portion (33), a foot portion (19, 20), a reaction member (34), and a beam member (36), thereby providing a reliable physical and electrical contact between the removable sensor member (15) and the PCB (11) as well as minimizing unwanted forces translated to the foot soldered joint during insertion and removal of the removable sensor member (15). Upon being inserted into the opening (27), the removable sensor member (15) is retained therein by a retention clip (55).
