Oil blocking type copper copper wiring terminal

Copper terminal blocks (oil blocking type), also known as copper terminal heads or copper noses, are connectors used for connecting wires and cables to electrical equipment. The material is generally made of T2 purple copper, and there are also brass ones. The appearance of the product is a pot shovel round head, with a fixed screw edge on the top side and a stripped copper core on the end. The types are divided into oil blocking type and tube pressure type, and the oil blocking type is better to resist air oxidation, Tin plating also involves coating the surface of a copper nose with a layer of tin to prevent oxidation and blackening. Copper noses are only used for wires larger than 10 square meters, and copper noses are not used for wires smaller than 10 square meters. Instead, cold pressed wire noses are used.
