Disclosed is an apparatus for measuring the contact resistance of an inlet connector for an electric vehicle. The apparatus for measuring contact resistance of an inlet connector for an electric vehicle according to one aspect of the present invention comprises: a housing; and a measuring unit formed to protrude from one end of the housing and including a plurality of contact resistance measuring modules having an insertion hole installed to couple a plurality of connection terminals of the inlet connector provided in the electric vehicle to measure the contact resistance of each connection terminal. The contact resistance measuring module includes: a coupling unit having an insertion hole for coupling the corresponding connection terminal, wherein a first conductor unit and a second conductor unit are insulated by an insulation unit and formed on the outer circumferential surface of the insertion hole; a power supply unit applying power to the coupling unit; a voltage measuring unit connected to the first conductor unit and the second conductor unit to measure the voltage flowing through the first conductor unit, the connection terminal inserted into the insertion hole, and the second conductor unit by means of power applied by the power supply unit; and a contact resistance measuring unit measuring the contact resistance of the connection terminal based on the measured voltage.

    전기자동차 인렛 커넥터의 접촉저항 측정 장치가 개시된다. 본 발명의 일 측면에 따른 전기자동차 인렛 커넥터의 접촉저항 측정 장치는, 하우징, 상기 하우징의 일단에 돌출 형성되며, 전기자동차에 구비된 인렛 커넥터의 복수의 접속단자가 결합되도록 삽입홀이 설치되어 각 접속단자의 접촉저항을 각각 측정하는 복수의 접촉저항 측정모듈을 포함하는 측정부를 포함하되, 각 접속저항 측정모듈은, 해당 접속단자를 결합하기 위한 삽입홀이 형성되며, 상기 삽입홀의 외주면으로 절연부에 의해 절연되는 제1 도체부 및 제2 도체부가 형성되는 결합부, 상기 결합부에 전원을 인가하는 전원 공급부, 상기 제1 도체부 및 제2 도체부에 접속되어, 상기 전원 공급부로부터 인가된 전원에 의해 상기 제1 도체부, 상기 삽입홀에 삽입된 접속단자 및 상기 제2 도체부를 흐르는 전압을 측정하는 전압 측정부, 상기 측정된 전압에 기초하여 상기 접속단자의 접촉저항을 측정하는 접촉저항 측정부를 포함한다.
