汽车中央电气接线盒是汽车整车电源分配及信号传输的中枢单元,其通过集合继电器、熔断器、二极管及一些电子模块,实现整车用电设备电源及控制信号的分配并对各用电设备及电线束进行过载或短路保护。汽车中央电气接线盒由于其特殊性和重要性,对材料要求比较高。聚苯醚(PPO)材料具有优异的电气性能、耐热性能和尺寸稳定性,而聚酰胺(PA)材料具有优异的力学性能、加工性能和低温韧性。通过这两种材料的优势互
Automotive central electrical junction box is the vehicle power distribution and signal transmission of the central unit, which through the collection of relays, fuses, diodes and some electronic modules to achieve vehicle electrical equipment power and control signal distribution and the use of electrical equipment And the wiring harness overload or short circuit protection. Due to its particularity and importance, the automobile central electrical junction box requires relatively high materials. Polyphenylene oxide (PPO) materials have excellent electrical properties, heat resistance and dimensional stability, while polyamide (PA) materials have excellent mechanical properties, processability and low temperature toughness. Through the advantages of these two materials each other
