PURPOSE:To eliminate damage of a terminal and contamination by dust attachment as well as prevent imperfect contact by carrying out cleaning of the terminal with a brush, when a printed circuit board is inserted in a connector, and protecting the terminal with a cover when removal is made. CONSTITUTION:A cover 7 to protect the whole of a printed circuit board 1 is furnished in a single piece therewith, and an L-shaped metal fitting 10 is fixed to the cover 7 at its inside. There a rod 5 is fixed, and a spring 6 is fitted on this rod 5. The end of a wiping cover 3 is fitted at the tip of this spring 6, and a brush 4 is implanted at the inside of this wiping cover 3. Because the brush 4 thereby cleans the terminal 2 when insertion is made into a connector, damage of the terminal 2 and attachment of dust can be prevented, that reduces imperfect contact with the connector to lead to enhance reliability of connection. |
