ELECTRIC APPARATUS

摘要

A female and male connecting structure is provided between a battery pack and a tool main body such that the battery is slidably attached and electrically connected to the tool main body. The female and male connecting structure includes male terminals provided on the tool main body and female terminals provided on the battery pack. A level difference is formed by a concave portion on a sliding surface of terminal portions of the male terminal in a thickness direction of the plate-shaped male terminal. The level difference is made at a plurality of positions to form concavo-convex portions. The sliding surface corresponds to an area with which a contact point of the female terminal comes into sliding contact, and oxidized films formed on the surfaces of the terminal portions can be removed and/or scraped by the concavo-convex portions.

主权项

1. An electric apparatus having a male terminal, the electric apparatus configured to be attached to a battery pack having a female terminal, wherein:
the male terminal is configured to be electrically connected to the female terminal by sliding the battery pack relatively with respect to the electric apparatus such that the male terminal is inserted to the female terminal in a sliding direction to come into elastic contact with the female terminal; the male terminal is configured to have a plate shape, the male terminal extending in the sliding direction and including a side surface with which the female terminal comes into sliding contact; a level difference portion is provided in a thickness direction of the male terminal on the side surface of the male terminal; and the level difference portion is configured to include an area in which the female terminal comes into sliding contact with the male terminal.
