  • Board connecting component and three-dimensional connecting structure using thereof
    Patent number: 7090502
    Abstract: The present invention includes a plurality of lead terminals made of a conductive material having spring elasticity; and insulative housing that buries a part of the region of lead terminal and fixedly retains a plurality of lead terminals in an arrangement having been set in advance. Lead terminal is composed of a buried part that is a part of lead terminal buried in housing; bottom end joint that is extended from one end of the buried part, is exposed through bottom end surface of housing, and extracted in width direction of bottom end surface; and flexibly changing part that is exposed from another end of the buried part through one wall surface orthogonal to bottom end surface, and is extended along this wall surface to top end surface facing to bottom end surface, being spaced from wall surface and top end surface.
