接线端子是用于实现电气连接的附件产品，在工业上属于连接器。随着工业自动化程度的不断提高和工业控制的要求越来越严格和精密，接线端子的需求量逐渐增加。电子行业的飞速发展，使得接线端子的用途越来越广泛，越来越多样化。

Wiring terminal is an accessory product used to realize electrical connection, which belongs to connector in industry. With the continuous improvement of industrial automation and the increasingly strict and precise requirements of industrial control, the demand for wiring terminals is gradually increasing. With the rapid development of the electronic industry, the use of wiring terminals is becoming more and more extensive and diversified.

端子的塑料绝缘材料和导电部件直接关系到端子的质量，它们分别决定了端子的绝缘性能和导电性。任何一个接线端子的故障都会导致整个系统工程的失败。警告案例不用多说，这里就不一一列举了。

The plastic insulating materials and conductive parts of the terminal are directly related to the quality of the terminal, which determine the insulation and conductivity of the terminal respectively. The failure of any terminal will lead to the failure of the whole system engineering. Needless to say, there are not many warning cases listed here.

为保证端子的质量和可靠性，防止相关故障的发生，建议根据产品的技术条件，研究制定相应的筛选技术要求，并有针对性地进行以下故障预防可靠性检查。例如：

In order to ensure the quality and reliability of the terminal and prevent the occurrence of relevant faults, it is recommended to study and formulate corresponding screening technical requirements according to the technical conditions of the product, and carry out the following fault prevention reliability inspection. For example:

在电气设备中，经常会发现个别芯线压接线未交付到位，或交付后无法锁定，接触不可靠。分析原因是个别安装孔的螺牙有毛刺或污垢。尤其是在使用出厂时已安装在插头插座上的后几个安装孔时，发现缺陷后，必须将其他已安装的孔中的压接线一一卸下，更换插座。

In electrical equipment, it is often found that individual core crimping wires are not delivered in place, or cannot be locked after delivery, and the contact is unreliable. The reason is that the screw teeth of individual mounting holes have burrs or dirt. Especially when using the last few mounting holes installed on the plug and socket when leaving the factory, if defects are found, the crimping wires in other installed holes must be removed one by one and the socket must be replaced.

此外，由于线径和压接孔径选择不当，或压接过程操作不正确，也会造成压接端不牢固的事故。为此，在成品出厂前，制造商应对交付的插头（座）样品的所有安装孔进行彻底的测试，即使用装卸工具模拟带有插针的电线或千斤顶到位，检查是否能锁定。根据产品的技术要求检查每根压接线的拉拔力。

In addition, due to the improper selection of wire diameter and crimping aperture, or the incorrect operation of crimping process, it will also cause the accident that the crimping end is not firm. Therefore, before the finished products leave the factory, the manufacturer shall thoroughly test all the mounting holes of the delivered plug (seat) samples, that is, use the loading and unloading tool to simulate the wire with pin or Jack in place and check whether it can be locked. Check the drawing force of each crimping wire according to the technical requirements of the product.

菲尼克斯端子厂家提醒大家，如果没有可靠的接线端子，就没有可靠的系统工程。预防和分析是每个企业必不可少的过程。通过接线端子的可靠性筛选，发现各种故障模式和故障机制。可以分析大量经验教训，消除各种隐患，为改进设计、工艺、检验和使用提供科学研究。

Phoenix contact terminal manufacturer reminds you that if there is no reliable terminal, there is no reliable system engineering. Prevention and analysis are essential processes for every enterprise. Through the reliability screening of terminal blocks, various fault modes and fault mechanisms are found. It can analyze a large number of experiences and lessons, eliminate various hidden dangers, and provide scientific research for improving design, process, inspection and use.
