How to use copper nose

Copper nose is also known as wire nose, copper wiring nose, copper tube nose, terminal blocks, etc., and various places and industries are called different. It is a connector for connecting wires and cables to electrical equipment. The top side is fixed on the side of the screw, and the end is the copper core of the wire and cable after peeling. Copper nose is used for more than 10 square meters, copper nose is not used for wires less than 10 square meters, and cold pressed nose is used instead. The copper nose has tin-plated and non-tinned, tube-pressed and oil-blocking surfaces.

Main scope of application

Household appliances, electrical industry, mechanical equipment factory, shipyard, distribution cabinet distribution box, etc. The product has good appearance and good electrical conductivity and safety.

Model 1: DT, made of T2 copper rod, the appearance of the product is a round head of the spatula, which can be used to seal the oil. The top side is fixed for the screw, and the end of the cable after the stripping is pressed with the terminal clamp. .

Model 2: DTG, stamped from T2 copper tube, is slightly lighter than DT and can replace DT when it is not required to seal the oil. Workmanship is simpler and faster than DT, and the price is relatively cheap.

Surface treatment

There are two commonly used ones:

1. Pickling, the acid-washed color and the original color of the red copper are basically the same, which can make the appearance of anti-oxidation more favorable for conduction.

2. Tin-plated, tinned copper nose surface is silver-white, which can better prevent oxidation and conduction, and can prevent the harmful gas diffusion of copper in conductive over-forming.

Installation Precautions:

1. The screws must be tightened.

2. The cable and copper nose must be inserted into place and pressed with pliers.
