  • Patent number: 7611389
    Abstract: The invention relates to a connector comprising a housing, a spring biased contact surface facing in a front direction of said connector for establishing a contact with a connector counterpart, said contact surface being movable within a working area against a spring force from a first rest position to a second connecting position by a force directed to the contact surface upon establishing a contact with the connector counterpart. In order to achieve a connector which makes it possible to keep the contact force at an appropriate and substantially constant level, said connector comprises a rolled spring with an outer end protruding in said front direction of said connector; said protruding end is attached to the housing of said connector, whereby said rolled spring is at least partly unrolled when said contact surface is moved against the spring force.

  • Publication number: 20070141906
    Abstract: The invention relates to a connector (11) comprising a housing (12), a spring biased contact surface (15) facing in a front direction of said connector for establishing a contact with a connector counterpart, said contact surface being movable within a working area against a spring force from a first rest position to a second connecting position by a force directed to the contact surface (15) upon establishing a contact with the connector counterpart. In order to achieve a connector which makes it possible to keep the contact force at an appropriate and substantially constant level, said connector comprises a rolled spring (14) with an outer end (19) protruding in said front direction of said connector. Said protruding end (19) is attached to the housing of said connector, whereby said rolled spring is at least partly unrolled when said contact surface (15) is moved against the spring force.

  • Patent number: 7094112
    Abstract: An insulative casing has a bottom face to be mounted on a board member. A conductive pin is disposed in the casing so as to be slidable in a first direction parallel to the bottom face. A conductive terminal is disposed in the casing and has at least one elastic piece which is always brought into contact with an outer periphery of the pin from a second direction perpendicular to the first direction. An elastic member is disposed between the pin and the terminal so that a tip end of the pin is projected from the casing while being retractable in the first direction.

  • Patent number: 7000792
    Abstract: A self-opening mechanism for a cap is capable of maintaining a restoring force of an elastic member and easily and tightly locking the cap and also releasing the locking. The mechanism has an elastic member (4) that is attached to an inner side of a hinge (3), and also a stopper block (7) is provided in a direction in which the elastic member (4) deforms so that the elastic member (4) deforms to an S-shaped form. Engagement pieces (10, 10a) in the cap (2) side are inserted into and fixed between hooks (16, 16a) of a push piece (18) and a protruding engagement pieces (15, 15a) to lock the cap more tightly. As the hook (16, 16a) moves upward and moves away from the protruding engagement pieces (15, 15a) when the push piece (18) is pressed, the engagement pieces (10, 10a) are released and a cover (2) automatically opens due to the restoring force of the elastic member (4).
