The sound-absorbing wire harness blanking cap comprises a fixing layer and a sound-absorbing layer, the sound-absorbing layer is fixed to the back of the fixing layer, the shape of the sound-absorbing layer is the same as that of the fixing layer, and the length and width of the sound-absorbing layer are smaller than those of the fixing layer; a flaring-shaped front line hole is formed in the center of the fixing layer, and a rear line hole is formed in the corresponding position of the sound absorption layer; the side edge of the fixing layer is provided with a front notch directly communicated with the front wire hole, and the corresponding position of the sound absorbing layer is directly communicated with a rear notch of the rear wire hole; an annular groove is formed in the periphery of the fixing layer, and an annular boss used for stopping is arranged behind the groove. And the fixing layer is made of a foaming PE (Poly Ethylene) material. According to the wire harness blanking cap, sealing after the wire harness passes through the center hole can be avoided, the wire harness blanking cap does not need to be integrated to the wire harness in advance, the wire harness structure is simplified, and the installation cost and use are reduced. And sound and air flow in the outer cavity can be effectively isolated. And the fixing device is suitable for fixing single-layer and double-layer metal plates. The foaming PE material is small in density, light in weight and free of peculiar smell.
本发明涉及一种吸音线束堵盖,包括固定层和吸音层,吸音层固定在固定层的背部,吸音层的形状与固定层相同,吸音层的长宽尺寸比固定层的长宽尺寸小;固定层中心设置扩口形的前线孔,吸音层对应位置设置后线孔;固定层侧边设置直通前线孔的前切口,吸音层对应位置直通后线孔的后切口;固定层周围设置环形的凹槽,凹槽后方设置用于止挡的环形凸台。所述的固定层采用发泡PE材料制作。本申请的线束堵盖能避免线束过中心孔后的密封,线束堵盖不用提前集成到线束,简化线束结构,减小安装成本和使用。能有效的隔绝外侧腔体的声音和气流。能适应单层和双层钣金的固定。通过材料发泡PE材料密度小、质量轻,而且没有异味。
