Claims

[Scope of Claim for Utility Model Registration] (1) In an electrical device in which a part of the case body is formed as a terminal box, and the opening of the terminal box is closed and sealed with a terminal cover; A stepped portion is provided at the tip of the through hole to form a space having a cross-sectional area larger than the diameter of the through hole, and a cylindrical body that communicates with an insertion opening provided in the terminal cover and that can be inserted into the through hole is provided. , a deformable engagement portion capable of engaging with the stepped portion formed in the space at the tip of the through hole is provided at the tip of the cylindrical body, and a tapered sealing pin having a wire insertion hole in the head. A sealing device for an electrical device, characterized in that a wire is inserted into an insertion hole provided in the terminal cover and the wire insertion hole, and both ends are bound. (2) In the sealing device for electrical equipment as set forth in claim 1 of the utility model registration claim; multiple slits are provided in the engaging portion at the tip of the cylindrical portion provided in the terminal cover to facilitate inward deformation. A sealing device for electrical equipment featuring:
