What means “easy entry”?

You can understand these two words literary. What entry is easy? The entry of a stranded wire into a terminal. The common terminal has a little step inside its body, that acts as an obstacle for stranded wire: some wires can be folded or do not go inside the terminal at all. This will change the nominal cross-section of the wire and affect the connection that can overheat in the future. Easy entry terminals do not have this obstacle inside their bodies, and the user easily puts the wire inside the terminals without any need in twisting it. This potion is widely used in the whole civilized world. Nylon insulated terminals and connectors, as well as insulated and non-insulated pin terminals made by KBT, have this useful option.
