1、大电流是多少？电流受电连接器及其端接的导线号所。1. What is the maximum current?The current is limited by the wire number of the electrical connector and its termination.2、额定电流是多少？额定电流应根据实际使用的芯数，查取接触件额定电流下降率Q值（可参照下表）芯数1~1011~2021~3031~5051~80≥80Q00.10.20.30.40.5再由公式：单个接触件额定电流I额≥单个接触件工作电流II÷（1-Q）计算出的接触件额定电流值，选择适合的接触对直径和电连接器接点型谱。2. What is the rated current?The rated current should be based on the number of cores actually used to check the Q value of the rated current reduction rate of the contact (refer to the table below).Number of cores1~1011~2021~3031~5051~80≥80Q00.10.20.30.40.5Then, according to the formula: rated current of single contact I额 ≥ working current of single contact II÷(1-Q), select the appropriate contact pair diameter and contact type spectrum of electrical connector.3、大电压是多少？大电压取决于电路间的间隙（即接触件间距和爬电距离）及连接器中所采用的绝缘材料。3. What is the maximum voltage?The maximum voltage depends on the gap between the circuits (i.e. contact spacing and creepage distance) and the insulation material used in the connector.4、电连接的操作和使用方法是什么？ 连接器的插头与插座连接时，因插头和插座有盲插功能，首先把头上引导插入插座内，然后旋转插头，待五键位定位后，再顺时针旋转螺帽，三卡钉迅速进入三曲线槽内，再旋转120°左右就会听到“咔哒”响声，这时候插头与插座已正确定位，并且插头、插座已被锁紧。分离时，轻轻用力向前推连接螺帽，并逆时针旋转，插头和插座就会很顺利的分离。连接器接线时，必须按对应的接点序号端接。连接器在未锁紧前，禁止通电使用。4. What is the operation and usage of electrical connection?When the plug of the connector is connected with the socket, because the plug and socket have blind insertion function, first insert the head guide into the socket, and then rotate the plug. After the five key position is positioned, then rotate the nut clockwise, the three clip quickly enters into the three curve groove, and then rotate about 120 ° to hear the "click" sound. At this time, the plug and socket have been correctly positioned, and the plug and socket have been locked Lock.When separating, gently push the connecting nut forward, and rotate it counterclockwise, the plug and socket will separate smoothly.When the connector is connected, it must be terminated according to the corresponding contact number.Before the connector is locked, do not use it with power on.5、订货说明要标注哪些内容？产品名称及型号；选配附件型号（根据需要）；数量；选配的电缆附件，压接取卸等专用工具需单独订货；如用户对电连接器有特殊要求时，我们将竭诚满足用户要求，改进或开发新的电连接器。5. What should be marked in the order description?Product name and model;Optional accessory models (as required);number;The optional cable accessories, crimping tools and other special tools need to be ordered separately;If users have special requirements for electrical connectors, we will wholeheartedly meet the requirements of users, improve or develop new electrical connectors.
