A cutter including a blade member () having an edge portion () for cutting a current-carrying member () and an insulating portion (); a gas generator () that generates high-pressure gas to move the blade member () toward the current-carrying member (); a receiving member () arranged on a side opposite to the edge portion () relative to the current-carrying member () and defining a receiving surface () for receiving the current-carrying member () upon cutting thereof; a stopper () configured to restrict forward movement of the blade member () such that the insulating portion () of the blade member () stops, after cutting of the current-carrying member (), at a position corresponding to a cut surface of the current-carrying member (); and an insulating protective member () positioned between at least one of the blade member () or the receiving member () and the current-carrying member () and configured to protect a surface of the current-carrying member () facing the at least one of the blade member () or the first inner cylinder member () are provided.

Cutter for a current-carrying member

A cutter includes a stopper with which a blade after cutting a harness with a cutting portion collides and stops. The blade includes a flexible guide portion which protrudes further in a forward direction of the blade than the cutting portion.

Cutter

A blade (), which includes a cutting portion () and an insulating portion (), is used as a blade () of a cutting apparatus (). The cutting portion () is made of a metal, and has a blade portion. The insulating portion () is formed by an insulating member, and forms a part that adjoins the blade portion in a direction opposite to an advance direction of the blade (). The cutting apparatus () is configured so that, when cutting a current-carrying member (), the blade () advances until the insulating portion () contacts cut faces of the current-carrying member () after the cutting portion () cuts the current-carrying member ().

Cutting apparatus, breaker, contactor, and electrical circuit breaker

Disclosed is a gas pressure actuator whose actuator body has a cylinder, a piston and a gas generator in which a powder is loaded, and the gas generator is positioned at an end portion of the cylinder. The gas generator injects a high pressure gas into the cylinder by the combustion of the powder, thereby moving the piston. The actuator body is provided with a coating which covers the entire actuator body from outside. The coating is a resin coating having electrically insulating, waterproof, and dustproof characteristics.
