Slip ring is a kind of rotary joint used in Electromechanical industry to solve rotating conduction or signal and gas-liquid transmission, and its application range is very wide. In the process of using the slip ring, most of the slip rings are directly connected with the wires of the application terminal. In order to adapt to different industries or products and reduce the wiring difficulty, a variety of wiring terminals often appear on the slip ring. Next, we will make a simple inventory of the terminals often used on the slip ring.

先来看各式电气接线端子，电气接头既有只传输功率的种类，也有信号功率集成一体传输的产品。后者比较常见的是哈丁接头，哈丁接头常见于风力发电机滑环上面，晶沛电子研制的中大型风力发电机滑环，导线外接的基本都是哈丁接头。而仅用来传输功率的就比较多了，比如菲尼克斯电气接线盒，在较为大型且路数较多的大型滑环上，这类接线盒也是比较常见的。

Let's first look at all kinds of electrical terminals. Electrical connectors not only transmit power, but also signal power integrated transmission products. The latter is more common in Harding joints, which are common on the slip rings of wind turbines. Harding joints are basically used for the external wires of the slip rings of medium and large wind turbines developed by Jingpei electronics. More are only used to transmit power, such as phoenix contact junction box, which is also common on large slip rings with more channels.

除了大型的滑环，小型滑环上通常也有电气接线端子，比如默孚龙电子的超微型系列滑环，使用的线材很软很细，很不容易进行焊接等操作，因此很多客户要求这类滑环在出货的时候，必须要为其安装相应的接线端子，根据滑环型号的不同，其端子具体型号也不同。还有一种接线端子，军工行业使用比较多，那就是航空接插件，一般情况下，我们都将其简称为航插，这类接口也是可以同时传输信号和功率的，默孚龙电子研制的滑环中，使用航插多的应该是个平台雷达滑环。

In addition to large slip rings, small slip rings usually have electrical terminals, such as the ultra micro series slip rings of mofuron electronics. The wire used is very soft and thin, which is difficult to weld. Therefore, many customers require that such slip rings must be equipped with corresponding terminals when they are shipped. According to the different slip ring models, The specific models of terminals are also different. There is another kind of connection terminal, which is widely used in the military industry, that is, aviation connector. Generally, we call it aviation plug-in for short. This kind of interface can also transmit signal and power at the same time. Among the slip rings developed by mobilon electronics, the one that uses aviation plug-in more should be a platform radar slip ring.

一类接线端子就是专业的接头，比如各类以太网接头、USB信号接头、DP接头、同轴线用的SMA接头以及光纤滑环用的各种类型的接头。以以太网接头为例，其又根据滑环的不同分为多类，一是我们常见的RJ45水晶接头，还有一类是工业以太网接头，再有一类就是监控摄像头上面的特殊的以太网胶壳，其相当于一个小型的接线盒，有的是独立的，有的以太网端子则和功率出现共用一个端子。，对于光纤滑环和高频滑环这两种特殊产品所使用的接口，我们这里就不再赘叙了。

A type of terminal block is a professional connector, such as various Ethernet Connectors, USB signal connectors, DP connectors, SMA connectors for coaxial lines and various types of connectors for optical fiber slip rings. Taking Ethernet connector as an example, it can be divided into several types according to different slip rings. One is our common RJ45 crystal connector, the other is industrial Ethernet connector, and the other is the special Ethernet rubber shell on the monitoring camera, which is equivalent to a small junction box. Some are independent, and some Ethernet terminals share the same terminal with power., The interfaces used by two special products, optical fiber slip ring and high-frequency slip ring, will not be described here.
