    • In a connector of male and female interlocking terminals, a lever is provided on a first connector in a freely pivoting manner. Guide pins provided on a second connector are inserted to guide channels formed in the first connector. A stopper block is provided on the top wall of the first connector. A spring is connected between the back side of the lever and the back side on the top wall of the first connector. The lever is pulled by the spring against the stopper block and is held at a disengaging position in which guide grooves formed inside the lever and the guide channels are aligned to form an inlet for the guide pins. Since the lever is automatically returned to the disengaging position by the spring even if the lever is accidentally turned, it is not necessary to re-rotate the lever to the disengaging position, making connecting operation smoothly.
    • 在公和母互锁端子的连接器中,杠杆以自由转动的方式设置在第一连接器上。 插入设置在第二连接器上的引导销以引导形成在第一连接器中的通道。 止动块设置在第一连接器的顶壁上。 弹簧连接在杠杆的后侧和第一连接器的顶壁上的后侧之间。 杠杆被弹簧拉靠在止动块上并且被保持在脱离位置,在分离位置中,形成在杠杆内部的引导槽和引导通道对准以形成用于引导销的入口。 由于即使杠杆意外地转动,杠杆自动返回到分离位置,也不需要将杠杆重新旋转到分离位置,使得连接操作平稳。

    • An antilock system for wheeled vehicles, wherein a reference velocity signal waveform which is obtained without differentiating the actual wheel velocity signal, is compared with the latter, thereby determining a point of time when brake pressure is to be relieved and/or a point of time when such brake pressure relief is to be stopped. Furthermore, in case an anomalous drop occurs in the wheel velocity, an additional reference velocity signal is obtained on the basis of the actual wheel velocity signal but without differentiating the latter, and it is compared with the actual wheel velocity signal, whereby the point of time when the brake pressure relief is to be stopped can be changed so as to cope with the anomalous drop of the wheel velocity.
    • 一种用于轮式车辆的防抱死系统,其中在不将实际车轮速度信号区分的情况下获得的参考速度信号波形与后者进行比较,从而确定制动压力要消除的时间点和/或时间点 当制动压力释放停止时。 此外,在车轮速度发生异常下降的情况下,基于实际的车轮速度信号获得附加的基准速度信号,但不区分后者,并将其与实际车轮速度信号进行比较, 可以改变制动压力释放停止的时间,以便应对车轮速度的异常下降。
