着スリーブ、iは被覆材す、dの基端部をケーブルa。A conventional protective cover that covers the connection parts of electric wires, cables, etc., as shown in Fig. 11, has two types: a sheathing material attached to the cable a on the right side, and a sheathing material d attached to the cable C on the left side. It consists of two members, and the protective cover is formed by overlapping the leading ends of the covering materials (A) and (d) and connecting the covering materials (A) and (D) with a mounting material (e) such as adhesive tape. Note that h is a crimp sleeve connecting conductors f and g of left and right cables a and c, i is a covering material, and the base end of d is cable a.

After inserting and attaching the cables in advance and connecting the conductors f and g of the left and right cables a and c, the respective sheathing materials s and d are connected, so the connection work is troublesome, and the connection is difficult. There is also the possibility that a gap may occur in the area. Furthermore, cables are coated with this material.

カバーを形成するものである。The method for manufacturing a protective cover of the present invention involves cutting along the longitudinal direction, and overlapping the cut edges of the cut portions to form a joining and overlapping portion, thereby forming a joint overlapping portion for electrical wires, cables, etc. A method of manufacturing a protective cover for covering a connection part, etc., wherein a mold is heated and immersed in plastisol, and the plastisol corresponding to the outer surface of the cough mold is cured to form a protective cover with a part to be cut. After forming the coating film, the mold together with the coating film is taken out of the plastisol, and then the portion of the coating film to be cut is cut along the longitudinal direction, and the coating film is placed in the mold. When removed from the protective cover and covering the connection portion, etc., a protective cover having the cut edge portions overlapped with each other is formed.

なしに、接続部等に外嵌することができる。According to the above method, by heating the mold and immersing it in plastisol, a coating film can be formed on the cough mold with hardened plastisol, and this coating film can be cut. When the planned portion is cut, the opposite side of the cut portion becomes a hinge portion, and the cut edges of the cut portion can be separated from each other. That is, by separating the cut edges of the covering film 51 from each other, an opening is formed in the covering film, which makes it easier to remove the covering film from the mold, and also allows the film to be removed and formed. The protective cover can be fitted onto the connecting portion or the like without being inserted from the end of the cable.
以下、実施例を示す図面に基づいて本発明を詳説する。 Hereinafter, the present invention will be explained in detail based on drawings showing examples.

好適である。An insulating tape 15 such as a self-bonding butyl rubber tape is wound around the exposed conductor 8 of the trunk cable 2a, and the overlapping piece 10 of the branch terminal 9 is inserted from the branch port 16 onto the insulating tape 15. The above-mentioned protective cover 1 is covered so as to protrude. Further, an insulating tape 17 is wrapped around the overlapping piece 10 of the branch terminal 9, the crimp terminal 14, the conductor protrusion 11, and the end of the branch cable 2b. As for the insulating tapes, for example, it is preferable to use a self-bonding butyl rubber tape 17a on the inside and an adhesive vinyl tape 17b on the outside.

形成するための切断予定部22(つまり、凹溝)が長手
方向に沿って形成されている。Therefore, to manufacture this protective cover 1, a mold 18 shown in FIG. 1 is used. That is, this mold 18 has a substantially heart-shaped cross section as shown in FIG. A protrusion 20 for forming the branch port 16 is formed. Furthermore, a cutting portion 22 (that is, a groove) for forming the above-mentioned cutting portion 4 is formed along the longitudinal direction on the upper end surface.
そして、この金型18を加熱して、第2図に示す様に、
プラスチゾルA中に浸漬し、該金型18の外面に対応す

成する。Here, plastisol is a fluid plastic that is also called paste, and when a plasticizer is added to PVC synthesized by emulsion polymerization, it becomes plastisol, which is a poor solvent at low temperatures. When this is heated, the plasticizer covering the surface of the PVC particles penetrates into the inside, producing a plasticized resin.
従って、上述の如く、金型18を加熱して、プラスチゾ
ルA中に浸漬すれば、その金型18の熱により、金型1

。Next, this mold 18 is taken out from the plastisol A together with the coating film 21, and the coating film 21 corresponding to the portion 22 to be cut of the mold 18 is cut along the longitudinal direction as shown by the dashed line in FIG. The coating film 21 is removed from the mold 18 by cutting to form a cut portion 4, and separating the cut edges 5 and 6 of the cut portion 4 from each other as shown by arrows B and C. , a protective cover 1 having a cut portion 4 in the longitudinal direction as shown in FIG. 4 can be formed. That is, this protective cover 1 has a hinge section 23 on the opposite side of the cutting section 4, and a cutting edge section 5,
6 can swing freely as shown by the arrow. In addition, when removing the coating film 21 from the mold 18, both end surfaces 24, 24
(See FIG. 1 I) When the coating film 21 is formed on the
The coating film corresponding to both end faces 24, 24 is removed.

For example, the protective cover 1 manufactured by this method may have branch connections or It can be used not only for right-angled connections but also for the terminal end of the cable 2, and also for other things that need to be covered and protected, in addition to the cable 2. This is because, by making the shapes of the molds 18 different, it is possible to form the coating film 21 in various shapes. The heating temperature of the mold 18 is such that when the mold 18 is immersed in the plastisol A, the thickness of the coating film 21 to be formed becomes a predetermined thickness.

By simply cutting one scheduled cutting section 22, it is possible to easily and quickly form the protective cover 1 provided with the cut edge sections 5 and 6 that overlap each other to form the joining and overlapping section 7. In addition, since this protective cover 1 has the cut end edges 5 and 6 overlapped to form a joined and overlapped part 7, the joining can be easily and reliably done without creating any gaps, and moreover, - When attaching the cover 1 to the connection part 3 of the cable 2, there is no need to insert the cover 1 into the cable 2 in advance, and after connecting the conductor 8, etc., it can be easily fitted onto the connection part 3. Can be installed. Furthermore, it can be easily attached when covering and protecting an object with a complicated shape that cannot be inserted from the end. Furthermore, since the protective cover 1 is made of one piece, it also contributes to cost reduction.
