Abstract:
1. A water-proofing connector-quipped electric-wire bundle comprising: a plurality of electric wires each having a conductor and an insulating cover covering the conductor, the insulating cover being locally removed at an end of each of the electric wires; a plurality of water-proofing plugs each made of material which is more pliable than the insulating cover, at least in an periphery thereof, and attached to a vicinity of the end of each of the electric wires so as to surround the insulating cover of the electric wire; a plurality of connector terminals each having a crimp portion crimped onto at least the end of each of the electric wires and the water-proofing plug attached to the electric wire; and a connector housing collectively holding the connector terminals while making in close contact with the peripheries of the water-proofing plugs onto which the respective connector terminals are crimped, wherein: the electric wires include a first electric wire having a first conductor, and a second electric wire having a second conductor with a greater cross-sectional area and a greater breaking elongation occurring when the second conductor will have been broken under tensile load than a cross-section area and a breaking elongation of the first conductor respectively; and the connector terminals include a first connector terminal attached to the first electric wire and a second connector terminal attached to the second electric wire, and wherein: the second connector terminal has, as the crimp portion, a second crimp portion which comprises only a second conductor-crimp portion crimped onto the second conductor in the insulating cover-removed end of the second electric wire so as to enfold the second conductor and a water-proofing plug-crimp portion crimped onto the water-proofing plug attached to the second electric wire so as to enfold the water-proofing plug; the water-proofing plug is attached to the first electric wire at such a position that an intermediate region where the insulating cover is exposed is ensured between the insulating cover-removed end of the first electric wire and a portion of the first electric wire to which the water-proofing plug is attached; and the first connector terminal has, as the crimp portion, a first crimp portion which includes a first conductor-crimp portion crimped onto the first conductor at the insulating cover-removed end of the first electric wire so as to enfold the first conductor, a water-proofing plug-crimp portion crimped onto the water-proofing plug attached to the first electric wire so as to enfold the water-proofing plug, and an intermediate crimp portion crimped onto the insulating cover in the intermediate region of the first electric wire so as to enfold the insulating cover.
