Insulated crimp connectors are  special parts that help connect  wires  together. They made from metal and covered  with plastic.  This  plastic layer keeps  electricity from escaping  and protect the  wires.  When you crimp the connector around a wire, it make a  strong bond  that holds wires. Using these connectors is  really  important for many projects, like fix a  car or home wiring. They  help ensure  everything works  safe and  correct.
