Abstract
A water cutoff structure of a covered wire comprising an upper side member and a lower side member for carrying out water cutoff to the covered wire by sandwiching a covered wire constituted by covering core lines by a pair of water cutoff members made of a resin respectively provided at the upper side member and the lower side member to be subjected to ultrasonic welding, in which the lower side member of the water cutoff structure is provided with a pair of locking portions and the pair of locking portions are respectively fitted to a pair of locking portions provided to correspond to the upper side member. Ultrasonic vibration energy is transmitted to concentrate on a welded portion.
Claims14
A water cutoff structure of a covered wire, in which a first member and a second member having first and second water cutoff portions made of a resin respectively are attached on the covered wire by ultrasonic welding to thereby provide water cutoff, wherein the first member has a first locking portion and the second member has a second locking portion, and the first and second locking portions are fitted to each other;
- wherein the first locking portion is formed to be along the first water cutoff portion so as to extend substantially orthogonal to a mating surface of the first member.
A water cutoff structure of a covered wire, in which a first member and a second member having first and second water cutoff portions made of a resin respectively are attached on the covered wire by ultrasonic welding to thereby provide water cutoff, wherein the first member has a first locking portion and the second member has a second locking portion, and the first and second locking portions are fitted to each other;
- wherein opposite sides of the first locking portion are provided with a first positioning projected portion and a first positioning receiving portion respectively and opposite sides of the second locking portion are provided with a second positioning receiving portion fitted to the first positioning projected portion and a second positioning projected portion fitted to the first positioning receiving portion, respectively.
A water cutoff structure of a covered wire, in which a first member and a second member having first and second water cutoff portions made of a resin respectively are attached on the covered wire by ultrasonic welding to thereby provide water cutoff, wherein the first member has a first locking portion and the second member has a second locking portion, and the first and second locking portions are fitted to each other;
- wherein the first and second locking portions are a projected portion and a recessed portion respectively which are fitted to each other;
- and
- wherein the recessed portion includes a groove portion at a bottom portion of the recessed portion and said groove portion is narrower than an upper portion of the recessed portion.
A water cutoff structure of a covered wire constituted by surrounding a plurality of core lines covered by a resin cover, in which a first member and a second member made of a resin are attached on the covered wire by ultrasonic welding to thereby provide water cutoff,
- wherein each of the first and second members has a lateral width wider than a width when the core lines are laterally arrayed, and
- molten resin is filled among the core lines to seal clearance among the core lines by applying ultrasonic vibration in a state that a pressure is applied from outer sides of the covered wire.
A water cutoff structure comprising:
- a wire;
- a first member including a first water cutoff portion and a projected portion;
- a second member including a second water cutoff portion and a recessed portion;
- wherein said wire is provided between said first member and said second member, said projected portion and said recessed portion are provided outside of the region where said first member and said second member contact said wire;
- and said projected portion is fit to said recessed portion;
- wherein said projected portion is formed to be along the first water cutoff portion so as to extend substantially orthogonal to a mating surface of the first member.
A water cutoff structure comprising:
- a wire;
- a first member including a first water cutoff portion and a projected portion;
- a second member including a second water cutoff portion and a recessed portion;
- wherein said wire is provided between said first member and said second member, said projected portion and said recessed portion are provided outside of the region where said first member and said second member contact said wire;
- and said projected portion is fit to said recessed portion;
- wherein opposite sides of said projected portion are provided with a first positioning projected portion and a first positioning receiving portion respectively and opposite sides of said recessed portion are provided with a second positioning receiving portion fitted to the first positioning projected portion and a second positioning projected portion fitted to the first positioning receiving portion, respectively.
A water cutoff structure comprising:
- a wire;
- a first member including a first water cutoff portion and a projected portion;
- a second member including a second water cutoff portion and a recessed portion;
- wherein said wire is provided between said first member and said second member, said projected portion and said recessed portion are provided outside of the region where said first member and said second member contact said wire;
- and said projected portion is fit to said recessed portion;
- wherein the recessed portion includes a groove portion at a bottom portion of the recessed portion and said groove portion is narrower than an upper portion of the recessed portion.
