Abstract

Rubber cover main bodies close opening shapes of terminal-connection openings when a battery pack is placed alone without being mounted on a tool body. When the battery pack is removed from the tool body and is placed alone, it is possible to regulate the entry of foreign materials, such as water or dust, by the rubber cover main bodies. Further, when body-side connection terminals are connected to battery-side connection terminals, the rubber cover main bodies themselves can be deformed due to elasticity according to the slide movement of the body-side connection terminals such that the body-side connection terminals can be inserted into the rubber cover main bodies. Accordingly, it is possible to protect the battery-side connection terminals in the terminal-connection openings such that the battery-side connection terminals are not damaged by regulating the entry of foreign materials from the terminal-connection openings without hindering electrical connection caused by slide mounting.

Claims12

Dependent claims

A battery pack that is configured to be capable of slidably moving on a tool body of an electric power tool served as a power source of the electric power tool and that includes battery-side connection terminals to which body-side connection terminals of the tool body are connected by a relative slide movement when the battery pack slides to be mounted, wherein:

a housing case that forms an exterior of the battery pack is provided with terminal-connection openings that extend in a slide direction of slide mounting with the inside and outside of the housing case communicating with each other, such that the body-side connection terminals can be connected to the battery-side connection terminals,
the terminal-connection openings are provided with foreign-material entry-regulating members that can close opening shapes of the terminal-connection openings when the battery pack is placed alone without being mounted on the tool body, and
the foreign-material entry-regulating members serve not to interfere with the connection when the body-side connection terminals are connected to the battery-side connection terminals.

Dependencies are inferred from the claim text.
