  • Publication number: 20150255885
    Abstract: A connection terminal core for a cable connector and a method of connecting the connection terminal core to a cable. The connection terminal core includes a connection terminal portion, a terminal core body, and a lead material. When heat is applied from the outside to the terminal core body in a state in which a cable-side connection wire is inserted into a cable-side connection wire fitting hole, the heat transferred through the terminal core body melts the lead member introduced into the cable-side connection wire fitting hole, and the terminal core body and the cable-side connection wire can be bonded to each other as the lead material is melted and then is solidified again. A faulty connection is prevented, and a neat external appearance is obtained after connection.
