To obtain a vehicle connection device capable of restraining occurrence of electric corrosion in a vehicle connection connector due to leakage of a current.SOLUTION: A vehicle connection device includes: a DC power supply 11 having a positive electrode connected electrically with a signal terminal 31, and a negative electrode connected electrically with a signal terminal 32, and capable of changing an output voltage; a switch 12 provided in a cable way P between the DC power supply 11 and the signal terminal 31, and opening and closing the cable way P; a detector 13 provided on the cable way P, and detecting a current value of a current flowing to the cable way P; a discrimination section for discriminating whether or not a leakage current 33 is flowing between the signal terminals 31, 32 based on the current value when the output voltage is a first voltage value, the current value when the output voltage is a second voltage value larger than the first voltage value, the first voltage value, and the second voltage value; and a switch control section for controlling the switch 12 to open the cable way P, when a discrimination is made that the leakage current 33 is flowing.SELECTED DRAWING: Figure 1

    【課題】漏れ電流による車両接続コネクタでの電蝕の発生を抑制することができる車両接続装置を得ること。【解決手段】正極が信号端子31と電気的に接続され、負極が信号端子32と電気的に接続される、出力電圧を変更可能な直流電源11と、直流電源11と信号端子31との間の電路Pに設けられ、電路Pを開閉するスイッチ12と、電路P上に設けられ、電路Pに流れる電流の電流値を検出する検出回路13と、出力電圧を第1の電圧値とした場合の電流値と、出力電圧を第1の電圧値よりも大きい値の第2の電圧値とした場合の電流値と、第1の電圧値と、第2の電圧値とに基づいて、信号端子31,32間に漏れ電流33が流れているか否かを判別する判別部と、漏れ電流33が流れていると判別されたときは、電路Pを開放するようにスイッチ12を制御するスイッチ制御部とを備える。【選択図】図1
