    • A column switch is provided with a rotary connector that makes electrical connection between a steering wheel and a vehicle by means of a coiled, flexible, flat cable 5 accommodated in a housing. The housing includes a lower housing defined by a base 1 of the column switch and an upper housing defined by a rotor 6 with a cancel cam 6f. The base 1 has a hollow cylinder 1a through which a steering shaft 2 is inserted in line with the hollow cylinder, and an annular groove 1b surrounding the hollow cylinder 1a and accommodating the flat cable 5 therein. The rotor 6 has an accommodating section 6c that closes the annular groove 1b, and a resilient fastening strap 6e that rotatably engages a fastening portion 1e formed on the hollow cylinder 1a. Since the same construction serves as both the base of the column switch and the housing of a rotary connector, the number of parts and assembly costs are minimized.
    • 列开关设置有旋转连接器,其通过容纳在壳体中的盘绕的,柔性的扁平电缆5进行方向盘和车辆之间的电连接。 壳体包括由柱开关的基座1限定的下壳体和由具有取消凸轮6f的转子6限定的上壳体。 基座1具有中空圆筒1a,转向轴2通过该中空圆筒1a与中空圆筒成一直线插入,环形凹槽1b围绕中空圆筒1a并容纳扁平线缆5。 转子6具有闭合环形槽1b的容纳部分6c和可旋转地接合形成在中空圆筒1a上的紧固部分1e的弹性紧固带6e。 由于相同的结构既用作立柱开关的底座又用作旋转连接器的壳体,所以部件数量和组装成本最小化。

    • This invention provides a rotary connector in which flexibility is imparted against the stress applied in the transverse direction of an elastic tongue by partially reducing rigidity of the elastic tongue plate in its transverse direction. Therefore, even if the elastic tongue or the flexible cable accidentally comes into contact with the inner wall of the housings due to a deviation from the tolerance of assembly, they do not come into strong contact. The rotor housing is rotatably fitted to the stator housing. The flexible cable 3 is spirally accommodated in the space defined by both housings. The terminal 4 is electrically connected to the conductor cable 31 exposed from the flexible cable 3. The support 5A resin-molds the terminal 4 and is fixed to at least one of the stator housing and the rotor housing. The elastic tongue 8 is fixed to the support 5A and is so disposed as to extend along the flexible cable 3. The width W1 of the elastic tongue 8 on the fitting side to the support 5A is relatively reduced to a smaller width than the width W2 on the opposed side so as to partially reduce rigidity in the transverse direction.
    • 本发明提供了一种旋转连接器,其中通过部分地降低弹性舌板在其横向方向上的刚性而使弹性舌片沿横向方向施加弹性。 因此,即使由于与组装公差的偏差,弹性舌片或柔性电缆意外地与壳体的内壁接触,所以不会发生强烈的接触。 转子壳体可转动地安装在定子壳体上。 柔性电缆3螺旋地容纳在由两个壳体限定的空间中。 端子4电连接到从柔性电缆3露出的导体电缆31.支撑件5A树脂模制端子4,并固定在定子壳体和转子壳体中的至少一个上。 弹性舌片8固定到支撑件5A上并且被设置成沿着柔性电缆3延伸。弹性舌片8在与支撑件5A的配合侧上的宽度W1相对地减小到比宽度W2更小的宽度 在相对侧,以便部分地降低横向的刚度。

    • An absolute encoder device comprises a code plate having a 1-track type absolute pattern whose minimum reading unit length is .lambda., a first incremental pattern with a pitch .lambda., and a second incremental pattern with pitch 2.sup.-n .lambda.. The device also comprises a detector section, which is movable relative to the code plate, which includes a detector detecting the absolute pattern and obtaining an absolute pattern signal, a detector detecting a first incremental pattern and obtaining a first incremental signal, and a detector detecting a second incremental pattern and obtaining a second incremental pattern signal. A shorter cyclic incremental signal is generated from the first incremental signal by interpolating and the shorter cyclic signal is synchronized with the second incremental signal. The absolute pattern signal, the second incremental signal and the synchronized first incremental signal represent the relative positional relationship between the code plate and the detector section.
