l Determine the cross-sectional area of the wire and the size of the screw
The ring terminal is a connector connecting the wire to the electrical equipment, one end is connected to the wire, and one end is fixed to the device through the screw, so as to achieve the desired effect. So you need to determine the size of the wire, and the size of the screws used.
l Select material
Ring copper terminals usually use brass and copper two materials, both materials have electrical conductivity, of which copper conductivity is better, the price of brass is more favorable.
l Size of connector required
The size of the terminal is mostly different, such as the diameter of the bolt hole and the size of the outside diameter, thickness, length, length of the terminal post, etc., which is also one of the factors that determines whether this product can make the circuit operate normally.
Determine these three factors can be selected terminals.
Usually, copper terminals are coated with a layer of tin on the surface to enhance the oxidation resistance of the terminal and extend the use of the terminal.
