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.

先來看各式電氣接線端子，電氣接頭既有只傳輸功率的種類，也有信號功率集成一體傳輸?shù)漠a(chǎn)品。后者比較常見的是哈丁接頭，哈丁接頭常見于風力發(fā)電機滑環(huán)上面，晶沛電子研制的中大型風力發(fā)電機滑環(huán)，導線外接的基本都是哈丁接頭。而僅用來傳輸功率的就比較多了，比如菲尼克斯電氣接線盒，在較為大型且路數(shù)較多的大型滑環(huán)上，這類接線盒也是比較常見的。

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.

除了大型的滑環(huán)，小型滑環(huán)上通常也有電氣接線端子，比如默孚龍電子的超微型系列滑環(huán)，使用的線材很軟很細，很不容易進行焊接等操作，因此很多客戶要求這類滑環(huán)在出貨的時候，必須要為其安裝相應的接線端子，根據(jù)滑環(huán)型號的不同，其端子具體型號也不同。還有一種接線端子，軍工行業(yè)使用比較多，那就是航空接插件，一般情況下，我們都將其簡稱為航插，這類接口也是可以同時傳輸信號和功率的，默孚龍電子研制的滑環(huán)中，使用航插多的應該是個平臺雷達滑環(huán)。

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.

一類接線端子就是專業(yè)的接頭，比如各類以太網(wǎng)接頭、USB信號接頭、DP接頭、同軸線用的SMA接頭以及光纖滑環(huán)用的各種類型的接頭。以以太網(wǎng)接頭為例，其又根據(jù)滑環(huán)的不同分為多類，一是我們常見的RJ45水晶接頭，還有一類是工業(yè)以太網(wǎng)接頭，再有一類就是監(jiān)控攝像頭上面的特殊的以太網(wǎng)膠殼，其相當于一個小型的接線盒，有的是獨立的，有的以太網(wǎng)端子則和功率出現(xiàn)共用一個端子。，對于光纖滑環(huán)和高頻滑環(huán)這兩種特殊產(chǎn)品所使用的接口，我們這里就不再贅敘了。

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.
