接线端子的作用是什么？

What is the function of the terminal block?

而现代的接线端子不止于此。接线端子作用很好表述，接线端子其实就是连接器的一种，是为了方便导线的连接而应用的，它其实就是一段封在绝缘塑料里面的金属片，两端都有孔可以插入导线。

Modern terminals are more than that. The function of the wiring terminal is well described. The wiring terminal is actually a kind of connector, which is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends to insert wires.

有螺丝用于紧固或者松开，比如两根导线，有时需要连接，有时又需要断开，这时就可以用端子把它们连接起来，并且可以随时断开，而不必把它们焊接起来或者缠绕在一起，很方便快捷。

There are screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time without welding or winding them together. It is very convenient and fast.

接线端子就是用于实现电气连接的一种配件产品，工业上划分属于连接器。随着工业自动化程度越来越高和工业控制要求越来越严格、精确，接线端子的需求量逐渐加大。

Wiring terminal is a kind of accessory product used to realize electrical connection, which belongs to connector in industry. With the higher and higher degree of industrial automation and the more strict and accurate requirements of industrial control, the demand for wiring terminals is gradually increasing.

如何选择接线端子器件？

How to select terminal devices?

根据所选择器件采用的标称值类型和绝缘材料，产品必须以低于额定值的电流工作，这样才能保证它们可在所希望的温度范围内可靠地工作。有时，适合于紧凑封装器件的材料可能无法很好地满足散热要求，因此此类接线端子器件使用时的电流必须大大低于额定值。

According to the type of nominal value and insulating material used by the selected devices, the products must operate at a current lower than the rated value, so as to ensure that they can work reliably within the desired temperature range. Sometimes, materials suitable for compact package devices may not meet the heat dissipation requirements well, so the current of such terminal devices must be much lower than the rated value.

导线及菲尼克斯端子故障怎么办？

How to deal with the wire and phoenix contact terminal failure?

导线及端子的故障可能是由于线束与车身（地线）之间或在有关开关内部短路所造成的。检查前应看在车身的端子固定是否牢靠，然后便可按下列步骤进行测试。拆下控制电脑ECU和传感器两侧的接线端子，再测量端子相应端子间的电阻。

The fault of wires and terminals may be caused by a short circuit between the harness and the vehicle body (ground wire) or within the relevant switch. Before inspection, check whether the terminals on the vehicle body are firmly fixed, and then carry out the test according to the following steps. Remove the wiring terminals on both sides of the control computer ECU and the sensor, and then measure the resistance between the corresponding terminals of the terminals.
