Terminal connection strip, method of manufacturing crimp terminal, wire crimpting device, and method of crimping wire

A wire crimping method for connecting by crimping an insulated wire where a conductor is covered with an insulating cover and a wire tip is formed by exposing the conductor on a distal end side of the insulated wire by peeling off the insulating cover on the distal end side of the insulated wire, and a closed-barrel-type crimp terminal provided with a hollow crimping section which allows the connection by crimping of the wire tip to each other by crimping the crimping section and the wire tip to each other, the wire crimping method comprising:

• a carrier cutting step in which a terminal connection strip which is constituted of a carrier formed in a strip shape, and the crimp terminal provided in plural each of which is connected at a wire insertion opening side thereof which opens to allow the insertion of the wire tip into the inside of the crimping section in a terminal axis direction to the carrier in a projecting manner along a carrier width direction, the crimp terminals connected to the carrier by way of connecting portions at predetermined intervals in a carrier long length direction is separated into the crimp terminal and the carrier by shearing the connecting portion in a carrier thickness direction by a carrier cutting means;
• a wire inserting step in which at least the wire tip of the insulated wire is inserted into the inside of the crimping section through the wire insertion opening;
• and
• a crimping step in which the insulated wire and the crimp terminal are connected by crimping to each other by crimping the crimping section into the inside of which the wire tip is inserted, the steps being performed in the order, wherein
• in the carrier cutting step, the carrier cutting means is slidably moved from a standby position which overlaps with the wire insertion opening in the carrier thickness direction to a cutting position which is on a side opposite to a side where the crimping section is provided with respect to the carrier in the carrier thickness direction and does not overlap with the wire insertion opening, and shears the connecting portion, and
• the wire inserting step is performed during a period in which the carrier cutting means is arranged at the cutting position.
