Speak a plug-in terminal requirements

Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. Terminal blocks are applied to facilitate the connection of wires. Advantages of terminal blocks: 1. Large contact area, high contact pressure, and can be connected horizontally at will 2. It has earthquake-resistant, self-locking, and anti-loosening functions 3. It can be installed with test slots and does not require maintenance 4. The contact points are airtight enough, not afraid of corrosion 5. Multi-strand wires can be directly connected without crimping the ends 6. Easy to use 7. Widely used

Most terminal blocks are composed of two plug-in and unpluggable connections. One part presses the wire tightly and then plugs it into the other part, which is soldered to the PCB board. The mechanical principle of the bottom connection and the anti-vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. It is a piece of metal sealed in insulating plastic. There are holes at both ends to insert wires, and there are screws for tightening or loosening. For example, two wires sometimes need to be connected, and sometimes they need to be disconnected. At this time, they can be connected with terminals, and they can be disconnected at any time without having to weld or twist them together, which is very convenient and quick. Terminal blocks are the hottest selling type of terminal on the market. Plug-in terminal blocks are suitable for the interconnection of a large number of wires without confusion. In the industrial power industry, there are a large number of special terminal blocks and terminal boxes, all of which are plug-in terminal blocks. These plug-in terminal blocks are conducive to installation and debugging in the early stage, and repair and maintenance in the later stage. At the same time, the most important function is to ensure sufficient current, a certain crimping area is to ensure reliable contact, stable metal materials, and strong high temperature resistance of plastics. The terminal blocks are made of flame retardant materials, which can prevent unnecessary accidents and minimize losses. If it is applied to the control circuit, the current coefficient will definitely be fine, mainly depending on its stability.
