接线端子在整个装配过程中，必须经得起预热区的高温以及通过波峰焊接传导至端子本体的温度。焊剂不得影响端子，必须易于清除，不能有任何残留物，整个装配过程必须可以用水清洗，预热温度常常达到100°C或更高，波峰温度达到280°C也并不少见。

　　In the whole assembly process, the terminal must withstand the high temperature in the preheating area and the temperature transmitted to the terminal body through wave soldering. The flux must not affect the terminals and must be easy to remove without any residue. The entire assembly process must be able to be cleaned with water. The preheating temperature is often 100 ° C or higher, and it is not uncommon for the peak temperature to reach 280 ° C.

　　穿孔的焊针必须准确定位，尺寸合适，均衡放置，并具备良好的可焊性，这样有利于插入和焊接。在整个装配过程中必须经得起热处理产生的高温冲击，在焊接中主要采用红外预热和对流预热使热量传导至焊针和锡盘界面以熔化焊锡膏。

　　The pierced pins must be accurately positioned, of suitable size, evenly placed, and have good weldability, which is conducive to insertion and welding. In the whole assembly process, it must withstand the high temperature impact produced by heat treatment. In welding, infrared preheating and convection preheating are mainly used to transfer heat to the interface between the solder pin and the tin plate to melt the solder paste.

　　触头抗熔焊性能差，在启动电动机或线路短路时，,大电流使触，头焊牢而不能释放，其中以纯银触头较易熔焊。

　　When the motor is started or the circuit is short circuited, the contact and the head can not be released due to high current. The pure silver contact is easy to be fused.

　　交流接触器的主触头应选用抗熔焊能力强的银基合金，如银铁，,银镍等。接线端子在光纤通信(传输)链路中，为了实现不同模块，设备和系统之间灵活连接的需要，必须有一种能在光纤与光纤之间进行可拆卸(活动)连接的器件，使光路能按所需的通道进行传输，以实现和完成预定或期望的目的和要求，能实现这种功能的器件就叫连接器。

　　The main contact of AC contactor shall be made of silver base alloy with strong welding resistance, such as silver iron, silver nickel, etc. In the optical fiber communication (transmission) link, in order to realize the flexible connection between different modules, equipment and systems, there must be a detachable (movable) connection device between the optical fiber and the optical fiber, so that the optical path can be transmitted according to the required channel to achieve and complete the predetermined or expected purpose and requirements. The device that can realize this function is called connector.

　　接线端子就是把光纤的两个端面精密对接起来，以使发射光纤输出的光能量能最大限度地耦合到接收光纤中去，并使由于其介入光链路而对系统造成的影响减到最小，这是光纤连接器的基本要求。

　　The terminal is to connect the two ends of the optical fiber precisely, so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its intervention in the optical link is minimized. This is the basic requirement of the optical fiber connector.

　　利用“Reakdyn原理”防止端子螺钉自松脱，在额定截面至10mm2的优选端子系列中，压线框均采用升降筒式结构.他们的作用原理是以所谓“升降筒原理”为基础的，不断改进的电路板技术使面板上安装的接线端子可承载的电流提升了很多。

　　The "reakdyn principle" is used to prevent the terminal screw from loosening. In the preferred terminal series with rated cross-section up to 10mm2, the wire pressing frame adopts the lifting cylinder structure. Their working principle is based on the so-called "lifting cylinder principle". The continuous improvement of circuit board technology makes the current carrying capacity of the terminal installed on the panel increase a lot.

　　接线端子在温度波动较大时仍具有良好的连接特性.，因为这样能避免因材料热膨胀系数的差异产生不同程度的热膨胀，因而也就能避免在端子中产生机械应力，避免连接的松脱。

　　The connection terminal still has good connection characteristics when the temperature fluctuation is large, because it can avoid different degree of thermal expansion due to the difference of thermal expansion coefficient of materials, so as to avoid the mechanical stress in the terminal and the looseness of connection
