摘要
安规是产品认证中对产品安全的要求,产品从设计到销售、到终端用户,贯穿产品使用的整个寿命周期,相对于销售地的法律、法规及标准产品安全符合性。安规的更新直接导致产品设计的巨大变化,其中GB 4943.1-2022防火防护外壳开孔的调整影响着产品结构和产品可靠性性能,是产品设计的难点和重点。产品设计时,在后窗上设置遮挡件,使被遮挡部分不属于潜在引燃源(PIS)滴燃区域的投影范围,这样就能使后窗上部分散热孔可以保持原有的开孔尺寸。在满足新标准的情况下,减少了开孔尺寸的改动,原有的模具可继续沿用,降低制作成本的同时提高了产品的性能。
Safety regulations refer to the requirements for product safety in product certification,and the product safety compliance with the laws,regulations and standards of the place of sale throughout the entire life cycle of the product from design,sales to terminal use.The update of GB 4943.1-2022 will lead to great changes in product design.Among them,the adjustment of the opening of the fire protection shell affects the product structure and product reliability performance,and is also the difficulty and focus of product design.During the product design,the blocking part is set on the rear window,so that the blocked part does not belong to the projection range of the PIS(potential ignition soure)drip-burning area.Because of the blocking part,the scattered hot holes on the upper part of the rear window can maintain the original large diameter holes.Under the condition of meeting the new standard,the change of the hole size is reduced,so that the original mold can continue to be used,reduce the production cost,and improve the product performance.
