ELECTRONIC ASSEMBLY HAVING A CIRCUIT BOARD WITH A SHOCK ABSORBER DEVICE

摘要

An electronic assembly (10) including a printed circuit board (PCB) (16), a housing (12), and a shock absorbing device (40) that is intermediate the printed circuit board (16) and the housing (12). The shock absorbing device (40) is formed of an insulative and compliant material, such as a thermoplastic elastomer material. The side walls of the shock absorbing device (40) defines a groove (46) surrounds and at least partially encloses the edges (26) of the printed circuit board (16). The shock absorbing device (40) defines an aperture (54) through which a fastener (36) is configured to pass to secure the shock absorbing device (40) to the housing (12) and thus securing the printed circuit board (16) within the housing (12). The shock absorbing device (40) is intermediate the fastener (36) and the printed circuit board (16) so that there is no direct contact between the fastener (36) and the printed circuit board (16) which could transmit impact shock directly from the housing (12) to the printed circuit board (16).
