    • The bending device comprises a hydraulic motor for moving a feeding table, and a hydraulic circuit including first and second switching valves which can be selectively switched between a speed control channel for supplying operating oil from a discharge-rate variable hydraulic pump to the hydraulic motor by way of a servo valve and a pressure control channel for supplying high pressure operating oil from the hydraulic pump to the hydraulic motor. When the feeding table provided with a chuck mechanism gripping a longitudinal material is moved to a bending mechanism to bend the material, control of the speed and application of axial compressive force can be conducted by switching of the first and second switching valves.
    • 弯曲装置包括用于移动供给台的液压马达和包括第一和第二切换阀的液压回路,该液压回路可以在用于从排出速率可变液压泵向液压马达供给工作油的速度控制通道之间选择性地切换, 伺服阀的方式和用于从液压泵向液压马达提供高压工作油的压力控制通道。 当设置有夹持纵向材料的卡盘机构的进给台移动到弯曲机构以弯曲材料时,可以通过切换第一和第二切换阀来控制速度和施加轴向压缩力。

    • In an IC socket for an electrical part, a contact pin electrically connecting a terminal of an electrical part and a printed circuit board is provided for a socket body of an IC socket. The contact pin comprises a sleeve having a space with one end opening, a plunger inserted into the sleeve through the end opening thereof to be vertically movable and an elastic member for urging downward the plunger. The sleeve is arranged to be vertically movable with respect to the socket body and is provided with a contact portion formed to an upper end thereof contacts a terminal of the electrical part to be electrically connected thereto and the plunger has a lower end contacting the printed circuit board to establish an electrical connection therebetween.
    • 在用于电气部件的IC插座中,为IC插座的插座本体提供电连接电气部件的端子和印刷电路板的触针。 接触销包括具有一个端部开口的空间的套筒,通过其端部开口插入到套筒中以可上下移动的柱塞和用于向下推动柱塞的弹性构件。 套筒布置成可相对于插座主体垂直移动,并且设置有形成于其上端的接触部分与电气部件的端子接触以与其电连接,并且柱塞具有接触印刷电路的下端 以在它们之间建立电连接。

    • A socket for electric parts is equipped with a socket body having a mounting face on which an electric part is mounted; contact pins fixed on the socket body, each having a contact portion, a trigger portion, and a spring portion; and a cover mounted on the socket body, free to move up and down. The end edge of the contact portion contacts a corresponding lead of the electric part and is configured to incline with respect to the end edge of the lead. The trigger portion and the spring portion are configured to project toward the center of the socket body. The width of the spring portion projecting toward the center of the socket body is such as to increase progressively in going to the base portion of the contact pin. In this way, a high pressure of contact between the lead and the contact pin and a sufficient wiping action are ensured, and a socket for electric parts capable of continued high performance over a long period of time is provided.
    • 一种用于电气部件的插座装有插座主体,该插座主体具有安装电气部件的安装面; 接触销固定在插座主体上,每个具有接触部分,触发器部分和弹簧部分; 以及安装在插座主体上的盖子,可自由上下移动。 接触部分的端部边缘接触电气部件的相应引线并且被配置为相对于引线的端部边缘倾斜。 触发部分和弹簧部分构造成朝向插座主体的中心突出。 朝向插座主体的中心突出的弹簧部分的宽度在逐渐向接触销的基部延伸时增加。 以这种方式,确保了引线和接触销之间的高压接触和足够的擦拭动作,并且提供了能够长期持续高性能的电气部件的插座。
