The invention relates to the field of safety of electric automobile circuit systems, and discloses an electric automobile power supply output busbar which comprises two busbar connectors used for connecting a power supply and a wire; two ends of the insulating connecting seat are fixed with the two busbar joints, and the insulating connecting seat is used for connecting and fixing the two busbar joints; two ends of the circuit break protection component are electrically connected with the two busbar joints respectively; and the insulating layer is wrapped outside. According to the application, the circuit break protection component is integrated with the two busbar joints, so that the power supply output busbar is provided with the circuit break protection component, when the current of the wire is larger and exceeds the maximum current of the circuit break protection component, the circuit break protection component starts circuit break protection, and the wire is disconnected from the power supply at the moment; therefore, the wire is not electrically connected with the power supply any more, the temperature of the wire is gradually reduced, the risk of spontaneous combustion caused by connection of the wire and the power supply is greatly reduced, the safety coefficient of the circuit system of the electric vehicle is improved, and the potential safety hazard of the circuit system of the electric vehicle is reduced.

    本申请涉及电动汽车电路系统的安全领域,电动汽车电源输出母排包括:两个母排接头,用于连接电源与导线;绝缘连接座,两端与两个母排接头固定,用于连接固定两个母排接头;断路保护元器件,两端分别与两个母排接头电性连接;绝缘层,包裹于外部。本申请通过将断路保护元器件与两个母排接头进行集成,使电源输出母排上自带断路保护元器件,使得在导线电流较大超过断路保护元器件的最大电流时,断路保护元器件开启断路保护,此时导线与电源断开,从而使得导线不再与电源电性连接,使得导线的温度逐渐下降,极大限度的降低了因导线与电源连接而引起自燃起火的风险,提高了电动汽车电路系统的安全系数,且减少了电动汽车电路系统的安全隐患。
