    • A phase-locked loop circuit includes: a phase and frequency comparing section configured to compare a phase of an external reference clock signal with a phase of a comparison clock signal, and generate an error signal corresponding to a result of comparison; an oscillating section configured to generate an internal clock signal of an oscillation frequency corresponding to the error signal; a frequency dividing section configured to generate the comparison clock signal by frequency-dividing the internal clock signal by a predetermined frequency dividing ratio; an oscillator control section configured to generate an oscillation control signal for controlling frequency of the internal clock signal output from the oscillating section on a basis of the error signal; and a frequency divider control section configured to generate a frequency division control signal for controlling a bias current of the frequency dividing section on a basis of the error signal.

    • The two coil spring terminals have the structure of double coil spring terminal including a small diameter coil spring terminal and a large diameter coil spring terminal. In this case, a terminal holder is provided with a clamping portion for clamping the large diameter coil spring terminal between the terminal holder and an internal circuit board. Specifically, the terminal holder is formed, in an upper end portion of its outer peripheral surface, with an annular groove which is adapted to be engaged with a small diameter portion formed in an upper end portion of the large diameter coil spring terminal. This omits fixation of the large diameter coil spring terminal to the internal circuit board, and necessity of soldering the two coil spring terminals respectively to the internal circuit board as a conventional art, enhancing mounting workability of the terminal holder.
    • 两个螺旋弹簧端子具有双螺旋弹簧端子的结构,包括小直径螺旋弹簧端子和大直径螺旋弹簧端子。 在这种情况下,端子保持器设置有用于将大直径螺旋弹簧端子夹持在端子保持器和内部电路板之间的夹紧部。 具体而言,端子座在其外周面的上端部形成有与形成在大径螺旋弹簧端子的上端部的小径部接合的环状槽。 省略了将大直径螺旋弹簧端子固定到内部电路板,并且需要将两个螺旋弹簧端子分别焊接到内部电路板上作为传统技术,从而提高了端子座的安装可操作性。
