Abstract

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the insulation holder and the wire connection ring has contact with the joining component.

First claim

The invention claimed is:

1. A joining body comprising:
a first resin component formed of a thermoplastic resin material and having a first opening;
a second resin component formed of a thermoplastic resin material and having a second opening;
a joining component configured to be inserted consecutively in the first opening of the first resin component and the second opening of the second resin component, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the first resin component and the second resin component, wherein a pocket portion into which the joining component is not inserted is the lower end side of the first opening, wherein
a lower end of the pocket portion, and a lower end of the joining component are spaced apart from each other; and
a welded part is formed by welding in at least a part of an area where each of the first resin component and the second resin component has contact with the joining component.

2. The joining body according to claim 1 , wherein
the joining component has a recess/protrusion portion formed on a surface thereof, and the welded part is formed at the recess/protrusion portion.

3. The joining body according to claim 2 , wherein
the recess/protrusion portion of the joining component is formed at both of parts of the joining component that correspond to inside of the first opening and inside of the second opening.

4. The joining body according to claim 2 , wherein
the recess/protrusion portion of the joining component is formed in a diamond knurl shape or a straight knurl shape, or in a groove shape along an outer circumferential direction.

5. The joining body according to claim 1 , wherein
a front end portion and a rear end portion of the joining component are located in the first opening and the second opening, respectively.

6. The joining body according to claim 1 , wherein
a rear end portion of the joining component is formed to be a flange portion greater than an opening size of the second opening, and
the flange portion of the joining component is formed so as to remain outside the second opening.

7. The joining body according to claim 1 , wherein
the first opening has a step having a smaller opening diameter than that at a side contiguous with the second opening, and
an outer shape of the joining member is formed in contact with the first opening at a second opening side with respect to the step of the first opening.

8. A joining body comprising:
a first resin component formed of a thermoplastic resin material and having a first opening;
a second resin component formed of a thermoplastic resin material and having a second opening;
a joining component configured to be inserted consecutively in the first opening of the first resin component and the second opening of the second resin component, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the first resin component and the second resin component, wherein a pocket portion into which the joining component is not inserted is the lower end side of the first opening; and
a welded part is formed by welding in at least a part of an area where each of the first resin component and the second resin component has contact with the joining component,
the first opening has a step having an opening diameter smaller than an opening diameter on a side connected to the second opening,
an outer shape of the joining component is formed to have contact with the first opening on the second opening side from the step of the first opening,
the joining component has a groove along an outer circumferential direction, below a largest outer-shape part of the joining component that is inserted into the first opening,
a diameter of the joining component at a position where the groove is formed is smaller than the opening diameter of the step of the first opening,
wherein a lower end of the pocket portion and a lower end of the joining component are spaced apart from each other, and
the welded part is formed at the groove of the joining component.
