ABSTRACT:
Electronic circuitry to assist in obtaining measurements of subsurface formation parameters is mounted on an elongated chassis member removably disposed within a tubular housing. One or more restraining assemblies are disposed along the length of the chassis. Each restraining assembly includes a cam member biased into engagement with the inner periphery of the housing to provide a substantially rigid restraint of the chassis within the housing. An inertial latch is used to constrain the cam member within the chassis for insertion within the housing. A pair of fixed contact members are angularly disposed about the chassis in radially spaced apart relationship with the cam member to provide three contact points with the housing.
