    • A connector structure comprising an electrically conductive plate having a plurality of through holes formed therein, an electrically insulated film formed on the inner wall of at least one of the through holes, an electrically conductive film formed on the inner wall of at least one other through hole, and an electrically conductive material of a low melting point provided within the through holes. The low melting point material provided in the through holes whose inner walls are coated with an electrically insulating film is insulated from the electrically conductive plate and such through holes may serve to receive signal propagating pins. The low melting point material in the through holes whose inner walls are coated with an electrically conductive film are tightly bonded to its inner wall due to the wettability between the low melting point material and the electrically conductive film so that such through holes may serve to receive a common potential pin to electrically stabilize the electrically conductive plate and to reduce electrical capacitance unnecessarily formed between the signal propagating pin receiving through holes. Thus, the connector structure is adapted for a high speed signal transmission without suffering substantial crosstalk noise.
    • 一种连接器结构,包括具有形成在其中的多个通孔的导电板,形成在至少一个通孔的内壁上的电绝缘膜,形成在内壁上的至少一个其它通孔 孔,以及设置在通孔内的低熔点导电材料。 设置在其内壁涂有电绝缘膜的通孔中的低熔点材料与导电板绝缘,并且这种通孔可用于接收信号传播销。 内壁涂有导电膜的通孔中的低熔点材料由于低熔点材料和导电膜之间的润湿性而紧密地结合到其内壁,使得这样的通孔可以用于接收 用于使导电板电稳定并且减少在信号传播销接收通孔之间不必要地形成的电容的公共电位引脚。 因此,连接器结构适用于高速信号传输,而不会产生实质的串扰噪声。

    • An electronic delay detonator comprises an electronic timer (100) and an electric detonator (200) fired by ignition of an ignition element. The timer includes an energy charging circuit (120) for storing electrical energy supplied from a power supply, a delay circuit (30) for counting a time period by using the electrical energy stored in the energy charging circuit to thereby output a trigger signal, and a switching circuit (140) for supplying the electrical energy stored in the energy charging circuit to the ignition element in response to the trigger signal. To an impact externally applied to the electronic delay detonator, a lower limit of an impact value in an induced detonation range of the electric detonator substantially overlaps with an upper limit of an impact value in a range in which the electronic timer is operable. Thus, no explosive remains misfired even in adverse use environments. When the damage of the quartz oscillator (131) is detected, the electric detonation is fired in response to the detected signal.
