ABSTRACT:
An electrical circuit board is supported within a tube by means of an aluminum support spine of semicircular section. The circuit board is mounted on the flat surface of the spine with a continuous layer of vibration-absorbing material between the circuit board and the spine. On the opposite side of the circuit board are a number of regularly spaced aluminum posts capped with rubber bumpers for engaging the inside surface of the tube. In order to hold the assembly within the tube and to absorb shocks, two rubber tubular members are disposed in grooves in the spine parallel to the longitudinal axis. The assembly may be introduced into the tube with the tubular members in a relatively contracted state and may subsequently be held firmly in position within the tube with the tubular members in a relatively expanded state.
