ASSEMBLIES FOR SUPPORTING ELECTRICAL CIRCUIT BOARDS WITHIN TUBES |
摘要 |
The present invention is directed to an assembly for supporting an electrical circuit board within a tube. The assembly comprises a circuit board, an elongated support spine extending longitudinally along the tube and supporting the circuit board and a shock absorbing device for holding the assembly within the tube. The circuit board is disposed parallel to a support surface of the spine with a gap therebetween and a layer of a vibration absorbing material is disposed in the gap between the circuit board and the spine. The vibration absorbing material preferably is an elastomer. Most preferably, the vibration absorbing material comprises a layer of a thixotropic elastomer together with a layer of a silicon elastomer. |
