  • Covered snap-fit terminals for connecting storage cells together
    Patent number: 7381093
    Abstract: An electric connector of the snap-in-fitting system comprises a couple of male and female connector members both made of an electrically-conductive material. The female connector member has a female engaging part or outer ring part for snap-in-fitting and the male connector member has a male engaging part or outer ring part to be fitted in and engaged with the female engaging part by snap-in-fitting. The interaction part in snap-in-fitting of the male engaging part and the female engaging part is an inclined engaging surface and adapted to apply load to the female engaging part so as to always urge the female engaging part outward. Preferably, the inclined engaging surface is a tapered surface convergent toward the male connector member side.

  • Button
    Publication number: 20050160562
    Abstract: A button body (11) has a housing (11A) for a tip end (12A) of the fixture (12) to be inserted therein. The fixture (12) has a shoulder (12C) between the tip end (12A) and a tubular portion (12B) formed continuously from the tip end (12A). The shoulder (12C) has an edge (12F) as a cutting portion to cut a fabric (1) with an insertion end (11E) of the housing (11A) of the button body (11). Without applying a big force to the edge (12F), the fabric can be cut easily regardless of the thickness of the fabric.
