法である。[Prior art] Watertight treatment of electric wire connections guarantees insulation,
Indispensable for preventing corrosion of electric wire conductors and conductor connection fittings. The traditional method for making electrical wire connections watertight is to spirally wrap multiple layers of self-adhesive insulating tape over the electrical wire connections, and then wrap a protective tape around the outside of the self-adhesive insulating tape.

特に、電線接続部が分岐接続部の場合、電線接続部の形
状が複雑であってテ−プの巻き付け作業がより一層困難
になり、水密性にも問題がある。However, in this method, it is necessary to wrap a narrow tape many times, which takes a long time.
In particular, when the wire connection part is a branch connection part, the shape of the wire connection part is complicated, making it even more difficult to wind the tape, and there is also a problem in watertightness.

れている。[0004] In order to eliminate such disadvantages, recently, a waterproof sheet in which a viscous sealant (for example, a viscous material mainly composed of uncrosslinked butyl rubber) is provided on one side of the protective sheet has been replaced with a viscous sealant. - Cover the wire connection part vertically with the cable facing inward,
Press the viscous sealant from above the protective sheet using a press,
A method has been proposed in which a viscous sealant is passed around the complicated space at the corner of the wire connection to make the wire connection portion watertight.

とはない。[0005] In this method of making watertight electric wire connections, when pressure is applied using a press, the viscous sealing material often protrudes from the vertically laminated seam or both lengthwise ends of the protective sheet. However, since the viscous sealant has sufficient tensile strength, it is possible to eliminate the transfer of the viscous sealant to the press die due to cutting, and there is no problem with the press operation.

る畏れがあり、水密性に悪影響を及ぼすと考えられる。[Problem to be Solved by the Invention] However, when the mold is released after pressurization, the protective sheet is pulled in the thickness direction as the press mold moves backward, and the viscous seal inside the protective sheet is damaged. There is a risk that the adhesive interface between the electric wire or electric wire connection fitting and the viscous sealing material will be peeled off as the protective sheet is pulled together with the protective sheet, which is thought to have a negative effect on watertightness.

防止には余り有効でない。[0007] In order to eliminate such unreasonableness, it is conceivable to use adhesive to bond the overlapped seams at both ends of the protective sheet of the waterproof sheet covered vertically, but in this case, the protective sheet is sealed by press pressure. A tensile force is applied to the sheet, and the tensile force is in the direction of opening the overlapped seams,
Since the adhesive layer cannot be expected to have much strength in such an opening direction, it is not very effective in preventing the viscous sealing material from extruding during the above-mentioned pressurization.

とを特徴とする構成である。[Means for Solving the Problems] The method of making a wire connection part watertight according to the present invention is a waterproofing method in which a viscous sealing material is provided on one side of a protective sheet, leaving at least both ends of the width of the protective sheet. The sheet is vertically attached and covered over the wire connection part by bending the sheet with both width ends shifted, and both width ends of the protective sheet are overlapped with one of the protruding protective sheets against the longitudinally applied covering main body. - This structure is characterized in that the waterproof sheet is folded over the longitudinally supported main body portion with its width end side facing outward, and in this state, the vertically supported waterproof sheet is pressurized.

In addition, the tensile force acting on the protective sheet can be supported by the adhesive part and can be prevented from acting as an opening force on the overlapping surfaces at both ends of the width of the protective sheet, making the overlapping area stable. It is possible to hold the viscous sealant and prevent the viscous sealant from protruding from the overlapping portion.

Also, with the electric wire w facing the length direction of the waterproof sheet S,

Then, both width end portions 11 and 12 of the protective sheet 1 are overlapped. In this case, since the length of one of the width ends 11 and 12 of the protective sheet 1 is longer than the length of the other 12, one width end 11 is larger than the other width end 12. stand out.

As shown in FIG. 2(D), the overlapping portion 10 is vertically spliced onto the protective sheet 1 of the covering main body portion b, and one width end portion 11 is placed on the protective sheet 1.
Fold it over with the side facing outward, and adhere the protruding portion 110 of the width end 11 of one of the protective sheets to the protective sheet 1 of the longitudinally spliced covering body part b using the pressure-sensitive adhesive 2, and then, Figure 2

対し剪断力が作用するだけである。Due to this pressurization, a tensile force is applied to the protective sheet 1, but one width end 1 of the protective sheet
In contrast to the tensile force, only a shearing force acts on the adhesive interface between the protruding portion 110 of the protective sheet 1 and the protective sheet 1 of the waterproof sheet longitudinally spliced covering body part b.

Since the overlapped portion 10 can be held stably, the viscous sealing material 3 can be sufficiently prevented from protruding from the overlapped portion 10.

It is possible to eliminate the tensile force acting on the sheet from acting as an opening force, thereby effectively preventing the viscous sealing material from protruding from the overlapped portion, and making it possible to prevent the viscous sealing material from protruding from the overlapping portion. Since adhesion with the press mold can be avoided, when the press mold is released, the viscous sealing material can be prevented from being pulled in the thickness direction and the adhesive interface between the sealing material and the wire connection portion being peeled off. Therefore, according to the present invention, the wire connection portion is sealed with a viscous seal.
Waterproof sheet with rubber material provides excellent watertightness.
