Abstract

The utility model discloses an insulated puncturing wire clamp for protecting a circuit. The insulated puncturing wire clamp comprises a top insulated housing, a bottom insulated housing, a puncturing blade, and a torque bolt. The puncturing blade is equipped with insulation paste. The top insulated housing and the bottom insulated housing tightly cling to each other so as to form a main line chamber and a branch line chamber. The puncturing blade penetrates the main line chamber and the branch line chamber. The torque bolt is arranged between the branch line chamber and the main line chamber. A temperature control switch is disposed on the middle of the puncturing blade and is composed of a support, a bimetallic strip, a push rod, and a contact switch. The contact switch comprises a fixed contact and a movable contact. The movable contact is produced by elastic conductive metal. The puncturing blade is electrically connected with the fixed contact and the movable contact and is abutted against the bimetallic strip. The push rod is arranged between the bimetallic strip and the movable contact. The utility model aims at providing an insulated puncturing wire clamp capable of protecting a cable line.
