14 is a DV wire provided with vinyl sheathing 15, 15, the vinyl sheathing at the tip is peeled off to expose the conductor 16 to the required length, twisted to one side and attached to the B sleeve 17.
It is connected using Further, an insulating tape 18 is wrapped around the entire exposed conductor wire 16 for insulation treatment. The engaging pieces 5a and 5b are expanded from above to the left and right of the insulated area in this way, and the release paper 13 stuck to the inner surface of the viscoelastic sealing layer 12 is peeled off to open the area. The part where the insulating tape 18 is wound between the wires 4 is accommodated in the main body 1, and the DV wires 14, 14 are connected at both ends thereof.
are clamped by the wire clamping parts 3, 3, respectively.

がはみ出したものは拭い取つてやればよい。 In this way, the sleeve cover, which is attached around the connection part of the electric wire and has the engaging pieces 5a and 5b combined, has a protrusion group 1 that projects inside the main body part 1.
1, the part around which the insulating tape 18 is wound is sandwiched and fixed, and both ends of this wire connection part are connected between the wire clamping part 3 and the DV wire 14 by the viscoelastic sealing layer 12 within each wire clamping part 3. The gap is sealed as shown in FIG. 5 to maintain a watertight state. Then, the viscoelastic sealing layer 1 is left over by sandwiching the DV wire 14.
2 escapes into the taper part 2 due to its own viscosity, and even in this taper part 2, the DV line 14
Fill the gap between the two and form a sealed part. At this time, the viscoelastic sealing layer 12 is blocked by the protrusion 11 and is filled into the tapered part 2 without flowing into the main body part 1 very much. Further, a portion of the excess of the viscoelastic sealing layer 12 may protrude outside from the wire clamping portion 3, but the protruding portion may be wiped off.

等の効果がある。[Effects of the invention] As described above, according to the sleeve cover of the invention, since the release paper 13 is attached to the inner surface of the viscoelastic sealing layer 12, (a) dust etc. are not adsorbed and the viscosity is reduced. Since this does not occur, the viscoelastic sealing layer 12 can already be applied at the factory shipping stage.(b) Workability is improved because the release paper 13 does not stick to the hands until it is peeled off, making work at heights safe and smooth. (c) Trial fitting can be performed to test the compatibility between the insulation part and the sleeve cover.

高い考案である。 Furthermore, since the release paper 13 is also attached to the end surfaces (cuts) of the viscoelastic sealing layer 12, the end surfaces do not bond to each other even if the viscoelastic sealing layer 12 is formed on the sleeve cover which assumes a cylindrical shape immediately after molding. Therefore, the viscoelastic sealing layer 12 can be easily used even in such a sleeve cover, making it a highly practical idea.
