Thereby, the support part 11 can stably support the displacement in the longitudinal direction of the conductor part 40 of the rib 10, and the thickness of the fitting part 12 is equal to or less than the thickness of the support part 11. The outer diameter of the portion 40 can be grasped flexibly and stably, and a more reliable fitting can be obtained. In addition, the thickness of the fitting portion 12 may be gradually reduced toward the tip so as not to lose the strength of fitting.

  FIG. 2 is a fitting diagram illustrating a fitting state between the insulated wire cover and the electric wire according to the first embodiment of the present invention. FIG. 2a-1 shows a fitting state when the outer diameter of the electric wire is thin, and the tip of the fitting portion 12 is fitted to the cut portion of the insulating coating 45, but the outer diameter of the electric wire is thin. A gap is formed toward the support portion 11 to such an extent that the fitting strength is not lost. FIG. 2a-2 shows a fitting state when the outer diameter of the electric wire is thick, and the front end portion of the fitting portion 12 is fitted to the cut portion of the insulating coating 45 and is completely set to the outer diameter of the conductor portion 40 of the electric wire. It is in close contact. FIG. 2b shows an arrow view of the rib 10 as viewed from the direction B of FIG. 2a-1. The surface of the fitting portion 12 that contacts the conductor portion 40 of the electric wire has a predetermined curvature that matches the conductor portion 40.

  FIG. 3 is a structural diagram of an insulated wire cover according to a second embodiment of the present invention. The insulated wire cover 100-2 has the same structure as the two-folded cover main bodies 1 and 2 in FIG. In FIG. 3 a-1, the rib 15 is fitted to the cut portion of the insulation coating, and fits freely to the outer diameter of the conductor portion 40 of the electric wire, and the conductor portion of the electric wire of the fitting portion 17. It is comprised from the rectangular column-shaped support part 16 which ensures the intensity | strength with respect to the shift | offset | difference to the longitudinal direction of 40.

FIG. 4a shows a fitting state when the outer diameter of the electric wire is thin, and the tip of the fitting portion 17 is fitted to the cut portion of the insulating coating 45, but the deformation is small because the outer diameter of the electric wire is thin. , J-shape is a slightly sagging shape. FIG. 4 b shows a fitting state when the outer diameter of the electric wire is thick, and since the outer diameter of the electric wire is thick, there is much deformation, and the J shape is more emphasized. In any case, flexible complete adhesion can be achieved in accordance with the difference in the outer diameter of the conductor portion 40 of the electric wire.

  FIG. 5 is a mounting diagram showing a mounting state of the insulated wire cover of the present invention. FIG. 5 a-1 shows a fitting state with respect to the electric wire having an intermediate thickness between the case where the outer diameter of the electric wire of FIG. 2 is thin and the case where the electric wire is thick. For this reason, the gap between the conductor part 40 of the electric wire and the fitting part 12 is also an intermediate gap. FIG. 5 a-2 shows a state in which the cover main bodies 1 and 2 are attached to the electric wires, closed, and fixed by the hooks 20 and the hook holes 25. FIG. 5b-1 shows a fitting state with respect to the electric wire having an intermediate thickness between the case where the outer diameter of the electric wire in FIG. 4 is thin and the case where the electric wire is thick. FIG. 5 b-2 shows a state in which the cover main bodies 1 and 2 are attached to the electric wires, closed, and fixed by the hooks 20 and the hook holes 25. In this manner, the deformation of the fitting portion 12 is intermediate and has a normal J shape.

  As described above, according to the present invention, it is possible to provide a hinge-type insulated electric wire cover having ribs that can be freely adapted to the outer diameter of the conductor portion of the electric wire and can secure the strength at the time of lateral displacement. Thereby, since the cover corresponding to every size of an electric wire is not required and can also be reused, the hinge type insulated wire cover with a high economic effect can be provided.
