To provide a lock device of a jumper coupler which is simple in structure and operation, enables double lock state, and has a high safety.SOLUTION: A lock device 10 of a jumper coupler 20 in which a lock pin 4 is provided on a receptacle 3 side fixed to a low pressure connection box (connection part 2) of a vehicle 1, and an operation lever member 7 having an engaging claw 711, which is so formed as to be capable of fitting to the lock pin, is rotatably provided on a plug 6 side connected to a jumper wire 5. A second lock pin 73 is formed at a tip 72 of the operation lever member 7, which is so extended from a rotation center 74 to a side opposite to the engaging claw 711 as to be a longer than a distance from the rotation center 74 to the engaging claw 711. Further, the low pressure connection box 2 comprises a rotatable regulation member 8 which is engaged with the second lock pin 73 thereby regulating rotation of the operation lever member 7 when the engaging claw 711 is in a state that the claw is fitted to the lock pin 4.SELECTED DRAWING: Figure 1
【課題】簡単な構造かつ操作で、二重ロック状態が可能な安全性の高いジャンパ連結器のロック装置を提供する。【解決手段】車両1の低圧ツナギ箱(接続部)2に固定されたレセプタクル3側に係止ピン4を配設し、ジャンパ線5に接続されたプラグ6側に係止ピンと篏合可能に形成された係合爪711を有する操作レバー部材7を回動可能に配設したジャンパ連結器20のロック装置10である。操作レバー部材7には、その回動中心74から係合爪711と反対側へ回動中心74から係合爪711までの距離より長く延設された先端部72に第2係止ピン73を形成した。また、低圧ツナギ箱2には、係合爪711が係止ピン4と篏合状態にあるとき、第2係止ピン73と係合して操作レバー部材7の回動を規制する規制部材8を回動可能に備える。【選択図】 図1
