In addition, the water stop portions 21c and 22b are also melted, and the core wire of each covered electric wire 10 is welded to the water stop portions 21c and 22b. Thereby, each covered electric wire 10 is subjected to a water stop process, that is, a process of stopping water entering through between the core wires is performed.
[0017]
Hereinafter, the water stop method of the covered electric wire 10 will be described.
First, the two covered electric wires 10 to be water-stopped are accommodated in the respective wire welding grooves 21 a and 21 b of the first member 21 of the water-stop member 20. Next, the second and third members 22 and 23 of the water stop member 20 are swung around the hinges 24 and 25.
Thereby, while covering the covered electric wire 10 between each electric wire welding groove | channel 21a, 21b of the 1st member 21, and each electric wire welding groove | channel 22a, 23a of the 2nd and 3rd members 22, 23, it is 1st. The covered electric wire 10 is sandwiched between the water stop portion 21 c of the member 21 and the water stop portions 22 b of the second and third members 22 and 23. In this state, the second and third members 22 and 23 are ultrasonically vibrated by an ultrasonic welding horn from the vertical direction in FIG. 2 on the side surface (upper and lower surfaces in FIG. 2) opposite to the wire welding grooves 22a and 23a. Vibrates.
[0018]
As described above, according to the above-described embodiment, the second and second covering wires 10 that stop water are accommodated in the wire welding grooves 21 a and 21 b of the first member 21 of the water stopping member 20. By swinging the three members 22 and 23 about the hinges 24 and 25, the wire welding grooves 21a and 21b of the first member 21 and the wire welding grooves 22a of the second and third members 22 and 23, respectively. , 23a, and each covered electric wire 10 between the water stop portion 21c of the first member 21 and each water stop portion 22b of the second and third members 22, 23. Pinch. In this state, each of the covered electric wires 10 is water-stopped by applying ultrasonic vibration from the vertical direction in FIG. 2 of the second and third members 22 and 23 and performing ultrasonic welding.
Therefore, the water stop process of the two covered electric wires 10 can be performed simultaneously. Thereby, the reduction of the number of parts of the water stop member 20 and the man-hour reduction of ultrasonic welding can be aimed at, and the cost concerning the water stop process of the covered electric wire 10 can be reduced.

Exciting ultrasonic vibration from outside.
Therefore, it is possible to simultaneously perform the water stop treatment of a plurality of covered wires, reduce the number of parts of the water stop member and reduce the number of steps for ultrasonic welding, and reduce the cost for the water stop treatment of the covered wires. Can be reduced.
[0020]
According to the water stop structure of the covered electric wire according to claim 2 of the present invention, the water stop member is formed with the wire welding grooves capable of accommodating the covered electric wires on both side surfaces, and the core wire of the covered electric wire in each of the electric wire welding grooves. The first member formed with a water stop portion that is ultrasonically welded to the first member is integrally connected to one side surface of the first member via a hinge, and is swung around the hinge. A second member in which a wire welding groove and a water stop portion corresponding to the wire welding groove and the water stop portion on one side surface of the first member are formed on a side surface facing one side surface of the first member; The other side of the first member is integrally connected to the other side of the first member via a hinge, and the other side of the first member is opposed to the other side of the first member while being swung around the hinge. The 3rd which formed the electric wire welding groove and the water stop part corresponding to the electric wire welding groove and the water stop part of a side surface And a member.
Therefore, it is possible to simultaneously perform the water stop treatment of a plurality of covered wires, reduce the number of parts of the water stop member and reduce the number of steps for ultrasonic welding, and reduce the cost for the water stop treatment of the covered wires. Can be reduced.
