Basic knowledge of terminal junction box

    When it comes to terminal junction box, you should first understand the terminal. The terminal is designed to facilitate the connection of wires. It is actually a piece of metal connecting piece sealed in insulating plastic. There are holes at both ends to insert the wire, and screws are used to fasten or loosen. For example, two wires need to be connected sometimes or need to be disconnected at any time. At this moment, the terminals can be used to solve this problem. It's very convenient and quick to weld them or wrap them together. And suitable for a large number of wire interconnection. The terminals (or wiring blocks) are combined according to the actual application, and then fixed in the plastic or aluminum alloy box, forming a widely used terminal box. In the electric power industry, there are special terminal boxes, all of which are single-layer, double-layer, current, voltage, common, breakable and so on. A certain crimping area is to ensure reliable contact and to ensure enough current.
