具有带震动吸收装置的电路板的电子组件
Abstract:
一种电子组件(10)，包括：印刷电路板(PCB)(16)；壳体(12)；和震动吸收装置(40)，其为印刷电路板(16)与壳体(12)的中间件。震动吸收装置(40)由绝缘和顺应性材料比如热塑性弹性体材料形成。震动吸收装置(40)的侧壁限定槽(46)，其包围并且至少部分地封闭印刷电路板(16)的边缘(26)。震动吸收装置(40)限定孔口(54)，而紧固件(36)被配置成穿过孔口(54)以将震动吸收装置(40)固定到壳体(12)，并且由此将印刷电路板(16)固定在壳体(12)内。震动吸收装置(40)是紧固件(36)和印刷电路板(16)的中间件，使得紧固件(36)与印刷电路板(16)之间不存在直接接触，而直接接触可能直接传递冲击震动从壳体(12)至印刷电路板(16)。
Abstract(English):

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).
