    • A snap hinge assembly for rotatably connecting a flip cover to a portable phone housing has only two parts, a hinge pin and a spring. The hinge pin is rotatably mounted in the housing and secured to the cover so as to rotate with the cover as it is opened and closed, and has a cam portion for engaging the spring. The spring is anchored in the housing and has a bearing portion for bearing against the cam portion as the pin rotates with the cover. The shape of the cam portion is such that the bearing portion is resiliently biased as the hinge pin rotates, and released at a predetermined orientation so as to snap the cover into either the open or closed position, depending on the direction of rotation of the pin. The cover is held by the engaging spring and cam surfaces in the open or closed position until positively urged towards the opposite end position.
    • 用于将翻盖可旋转地连接到便携式电话机壳的卡扣铰链组件仅具有铰链销和弹簧两部分。 铰链销可旋转地安装在壳体中并固定到盖上,以便在盖被打开和关闭时与盖一起旋转,并且具有用于接合弹簧的凸轮部分。 弹簧固定在壳体中,并且当销与盖旋转时,具有用于支承凸轮部分的轴承部分。 凸轮部分的形状使得当铰链销旋转时,轴承部分被弹性地偏置,并且以预定方向释放,以便根据销的旋转方向将盖卡入打开或关闭位置 。 盖被接合弹簧和凸轮表面保持在打开或关闭位置,直到被朝向相对的端部位置被迫动。
