Lateral support for downhole electronics

An apparatus for use in a borehole intersecting an earth formation, the apparatus comprising:

• a downhole tool comprising an outer member configured for conveyance in the borehole;
• a probe body positioned inside the outer member;
• an electronics carrier positioned inside the probe body;
• and
• a lateral support system comprising:
• a plurality of members cooperating to maintain a relative position of the electronics carrier with respect to the probe body, the plurality of members comprising:
• an outer support ring within the probe body having an axial passage therethrough for receiving a portion of the electronics carrier, the outer support ring having an inner surface;
• an inner support ring within the probe body having an axial passage therethrough for receiving a second portion of the electronics carrier, the inner support ring having an outer surface;
• and
• a biasing member configured to urge a member of the plurality of members against an inner surface of the probe body by urging the outer surface of the inner support ring against the inner surface of the outer support ring, and thereby maintaining separation of the probe body and the electronics carrier.
