The invention discloses a connecting wire positioning clip suitable for high voltage, comprising an insulating casing, wherein a first wire clamp plate is disposed on the left side of the inner cavityof the insulating casing, a first wire guiding cylinder is connected to the left side of the first wire clamp plate, the inner cavity of the first wire guiding cylinder is provided with a first wire,and the right side of the first wire clamp plate is connected with a dovetail shaped bump. Due to the matching of the first wire clamp plate, the first wire guiding cylinder, the first wire, the dovetail shaped bump, the fixing block, the limiting block, the first snap spring, the fixing plate, the semi-arc snap block, the second wire clamp plate, the dovetail shaped groove, the second wire guiding cylinder, the snapping rod, the supporting seat, the cross bar, the blocking bar, the second snap spring, and the fixture block, the invention may fully clamp the first wire and the second wire toenhance the clamping effect of the positioning clip, which solves the problem that the clamping function of the existing positioning clip is poor, avoids the phenomenon that the wire is separated fromthe inside of the positioning clip, and is worthy of popularization.
