Crimp terminal, connection structural body and connector

摘要

In a female crimp terminal including a pressure-bonding section for permitting pressure-bonding and connection to an aluminum core wire of an insulated wire, the pressure-bonding section is configured in a hollow sectional shape by a plate material, and a long length direction weld portion in a long length direction is welded, a forward part in the hollow sectional shape is caused to take an almost flat plate-shaped sealing shape and a width direction weld portion in a width direction is welded.

主权项

1. A crimp terminal including at least a pressure-bonding section for permitting pressure-bonding and connection to a conductor portion of an insulated wire,
wherein the pressure-bonding section is configured from a plate material having a hollow sectional shape, and has a first welding bead formed from one end side to the other end side in a long length direction of the pressure-bonding section, the first welding bead penetrating the plate material from a surface side to a back face side, a sealing portion for carrying out sealing to superpose the plate material and is provided on the one end side in the long length direction of the pressure-bonding section in the hollow sectional shape, an opening portion into which the insulated wire can be inserted is provided on the other end side in the long direction of the pressure-bonding section in the hollow sectional shape, and a second welding bead is formed in a direction intersecting with the first welding bead formed in the long length direction between both ends in the long length direction of the sealing portion in a region where the plate material s superposed like a plane.
