Abstract: Contacts are formed by a metal injection molding method using metallic fine particle powder as the material therefor. The contacts have a substantially rectangular base portion and an elastic arm that extends upward from one end of an upper surface of the base portion, supported in a cantilever fashion. The portion where the arm is attached to the base or a fixed end portion, has a comparatively large rectangular cross section. The cross sectional area gradually decreases toward the distal end of the arm. An electrical contact tip is formed at the distal end of the arm.

Abstract: The low insertion force type connector has a housing, contacts, shafts, main bodies of the shafts that urge the contacts, cams which maintain the mating connector at a depth that immediately precedes complete engagement, hook-shaped members which perform a gradually increasing locking operation with the mating connector, a lever, and a cover member. After the connectors have been engaged with each other to a depth that immediately precedes complete engagement, the lever is operated so that the cams are released. As a result, an electrical connection between the connectors is established by the main bodies; furthermore, the connectors are caused to approach each other even more closely by the hook-shaped members, so that wiping is performed, and so that the connectors are locked to each other.
