Claims

[Scope of Claim for Utility Model Registration] (1) Connecting the core wires of a pair of parallel power cords to the rear ends of two plug blades arranged in parallel at a predetermined interval, and forming a molded body made of an insulating material such as synthetic resin. In an insertion plug having a part of the plug blade protruding, a breaker that interrupts the circuit due to overcurrent is arranged in the main body, and one electrode of the breaker is extended to form one of the plug blades. . An insertion plug characterized in that the other electrode is used as a connection terminal for the power cord, and the head of the return button of the breaker is arranged in the through hole on the side surface of the main body. (2) Attach metal fittings that hold the end electrodes of the cylindrical fuse to the rear end of one or both of the plug blades and the core end of the power cord connected to the same end, and make the breaker into a cylindrical type. The plug according to claim (1), characterized in that it is a fuse. (3) A disk having a protrusion made of an insulating material and a metal fitting that clamps the end electrode of the cylindrical fuse are fixed to the rear end of the plug blade, and the plug blade holding the cylindrical fuse is connected to the plug blade. 3. The insertion plug according to claim 2, wherein the plug is inserted into the main body in the longitudinal direction of the plug, and the plug blade is rotated at a substantially right angle and latched by the protrusion. (4) Hold the plug blade to which the clamping bracket of the cylindrical fuse and the clamping bracket of the connecting piece connected to the unconnected power cord core end of the cylindrical fuse are fixed by an insulating material, and attach the clamping bracket to the upper and lower surfaces of the insulating material. 3. The insertion plug according to claim 2, wherein the plug is latched onto the main body inserted in the longitudinal direction of the plug blade by a projection provided therein.
