Application range of U-shaped terminal | earth terminal block
Rail-type terminal-the screw is made of high-strength copper alloy, the conductor is made of electrolytic copper, and the crimping frame is made of alloy copper that resists stress crack corrosion. The unique crimping structure has good self-locking and anti-loosening. performance. These metal surfaces are also tin-plated or nickel-plated for protection. All copper terminals can avoid the battery effect of steel metal parts and copper wires in a humid environment.
The rail terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends for the wire to be inserted. There are screws for fastening or loosening, such as two wires. Sometimes If you need to connect, and sometimes you need to disconnect them, you can connect them with terminals and disconnect them at any time without having to weld them or twist them together, which is very convenient and quick. Moreover, it is suitable for a large number of wire interconnections. In the power industry, there are special terminal blocks and terminal boxes, which are all connected terminals, single-layer, double-layer, current, voltage, ordinary, breakable, and so on. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.
When the terminal is used for its intended purpose, it provides an electrical connection between the leads inside the appliance, or between the leads and the components. Some features that require special attention, such as the reinforced insulation required during electrical assembly; the creepage distance between lead terminals of different polarities, or between lead terminals and uncharged metal bodies, and the brackets of adjacent lead terminals, etc. , These characteristics need to be judged corresponding to the standards of this electrical appliance.
