Electrical apparatus

摘要

An electrical apparatus that can prevent erroneous attachment of a fuse is provided. A PCU includes a housing having a surface. A fuse storage space is formed in the housing. The fuse storage space communicates with a region outside of the housing through an opening formed at the surface. The PCU further includes a cover member covering the opening, and an overcurrent-protection fuse located in the fuse storage space. The cover member includes a cover body closing the opening, and a projection section projecting inward of the fuse storage space relative to the cover body. The projection section interferes with the fuse when the fuse is attached erroneously in the fuse storage space.

1. An electrical apparatus comprising:
a housing having a surface, a space being formed in said housing, said space communicating with a region outside of said housing through an opening formed at said surface; an overcurrent-protection fuse located in said space; and a cover member made of metal, covering said opening, wherein said cover member includes a cover body and a projection section, the cover body being a part of a top surface of the cover member, wherein the cover member forms a gap between said top surface of the cover member and a body of said fuse, and wherein the projection section protrudes:
inward and away from said top surface of the cover member andinto said gap and towards the body of said fuse, and when said fuse is attached properly in said space, an insulation distance between said cover member and said fuse is ensured, and when said fuse is erroneously attached in said space, said projection section mechanically interferes with the body of said fuse to disallow attachment of said cover member to said housing.
