Electronic Spices SV2-4 25A Blue color 16-14 AWG wire gauge 4mm pitch Hard plastic insulated crimp Wire Connector  (Blue, Pack of 20)

This is a small blue male crimp connector. These types of connectors are used for making connections between two wires or cables. The male connector gets attached by inserting the strip end of the standard wire to the hollow portion by using a special connector tool. Then, you can easily connect it with a female connector to make a strong electrical path. The best benefit of these connectors is that they can easily terminate the connection between electric wires. They are reliable and long lasting. They can easily be disconnected. The tin plating is also beneficial to protect the connection from electrical interference.
