To provide an unauthorized connection detection device that allows the connection of an unauthorized apparatus to be detect at low cost when an apparatus that does not include a communication line is connected to a connector of an ECU or the like on a vehicle side.SOLUTION: One or more protrusions are formed at a predetermined portion of one 32 of a pair of connectors 31 and 32 that connect regular units 10 and 20 to each other, one or more switch portions capable of detecting the protrusions are installed at a predetermined portion of the other 31 of the pair of connectors, and unauthorized connection is detected based on a detection state of the protrusions. Alternatively, a conductor pattern is formed at a predetermined portion of one 32 of a pair of connectors 31 and 32 that connect regular units to each other, one or more switch terminals capable of detecting the conductor pattern are installed at a predetermined portion of the other 31 of the pair of connectors, and unauthorized connection is detected based on a contact formation state of the switch terminals.SELECTED DRAWING: Figure 1
【課題】車両側のECU等のコネクタに通信線を含まない機器を接続する場合に、不正な機器の接続を低コストで検知可能にする不正接続検出装置を提供する。【解決手段】正規のユニット10、20同士を接続する1対のコネクタ31、32の一方32の予め定めた部位に1つ以上の突起部を形成し、前記1対のコネクタの他方31の予め定めた部位には前記突起部を検知可能な1つ以上のスイッチ部を設置して、前記突起部の検知状態に基づいて不正接続を検出する。又は、正規のユニット同士を接続する1対のコネクタ31、32の一方32の予め定めた部位に導電体パターンを形成し、前記1対のコネクタの他方31の予め定めた部位には前記導電体パターンを検知可能な1つ以上のスイッチ端子を設置して、前記スイッチ端子の接点形成状況に基づいて不正接続を検出する。【選択図】図1
