The invention discloses a heat-insulation pressure-resistant automobile cable, which comprises a cable inner core, a connecting layer, a positioning shaft, a circumferential connecting assembly, a radial extending assembly and a heat insulation layer. The heat insulation layer is mounted on the outer side of the periphery of the connecting layer; and the heat insulation layer is correspondingly inserted into the multiple inserting grooves in the outer side of the periphery of the connecting layer through multiple abutting strips in the heat insulation layer. The radial thickness of the abutting strips along the heat insulation layer is larger than the radial depth of the inserting grooves along the connecting layer. In this way, an extrusion gap is formed between the heat insulation layerand the connecting layer, first air heat insulation is conducted through the extrusion gap, then second heat insulation is conducted through the heat insulation layer, and in addition, due to the existence of the extrusion gap, the bearing degree of extrusion deformation is higher, and extrusion resistance is higher.

    本发明公开了一种隔热耐压式汽车用电缆,包括电缆内芯、连接层、定位轴、周向连接组件、径向延伸组件、隔热层;本发明在连接层的四周外侧安装隔热层,隔热层通过内部的多个抵接条分别对应插接于连接层四周外侧的多个插接槽内,并且抵接条沿着隔热层的径向厚度大于插接槽沿着连接层的径向深度,如此隔热层和连接层之间形成挤压间隙,通过挤压间隙进行第一道空气隔热,再通过隔热层进行第二道隔热,另外,挤压间隙的存在使得挤压形变的承受度更高、抗挤压力更强。
