Copper nose is also called wire nose, copper wiring nose, copper tube nose, terminal block, etc., which is called differently in different places and industries. It is a connector used for connecting wires and cables to electrical equipment. The top side is a fixed screw edge, and the end is a stripped copper core of wires and cables. Copper nose shall be used for wires larger than 10 square meters, and cold pressed nose shall be used instead of copper nose for wires smaller than 10 square meters. Copper nose can be divided into surface tinned and non tinned, tube pressing type and oil plugging type. This product is commonly used in household appliances, electrical industry, mechanical equipment factory, shipyard, distribution cabinet, distribution box, etc. The product has good appearance specification, good conductivity and safety. 1. The terminals and joints of the terminal block are made of high-quality copper, tinned outside, anti-oxidation, anti-corrosion, silver-welded tail seam, and ribbed in the inner hole to increase the anti-oxidative pressure. 2. In the structural design of copper terminals, more attention is paid to the two characteristics of convenient wiring and firm connection. Copper terminals and other terminals can be compatible with each other, which greatly improves the flexibility. Secondly, the connection is relatively firm. The connection is very convenient, simple and strong, and does not require subsequent maintenance.Surface treatment: 1. Pickling, the color after pickling is basically the same as the natural color of red copper, which can play a beautiful role in oxidation resistance and conductive. 2. Tin plating. The surface of the copper nose after tin plating is silver white, which can better prevent oxidation and conductivity, and prevent the diffusion of harmful gases generated by copper in the conductive process. Precautions for installation: 1. The screws must be tightened, 2. The cable and copper nose must be inserted in place and pressed with pliers.1.
