DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a covering method and a protective cap according to an embodiment of the present invention will be described with reference to FIG. That is, the protective cap 5 of the present invention is a “finger-suck” -shaped cap body 6 that covers the wire splice 3 of the exposed conductor group 2 at the end of the wire group 1, and extends from the entrance side of the cap body 6. In the one having the strip-shaped flexible fixing piece 7 integrally, a thick abutting portion 8 having an abutting surface 9 orthogonal to a longitudinal center line 11 of the cap body 6 is provided on the bottom of the cap of the cap body 6. Is provided with a slit-shaped conductor entrance 10 extending substantially over the entire length of the cap body 6, and the cap body 6, which is covered with the electric wire group 1, is bent by fixing the fixing piece 7 to expose the exposed conductor. Group 2 is a conductor doorway 10
It can be taken out from.

The above protective cap 5 is covered by the following procedure and method. That is, (see (C) of FIG. 1) the electric wire group 1 is bundled by hand, inserted into the hollow portion of the protective cap 5, and the end of the exposed conductor group 2 is abutted against the abutting portion 8 so that the ends are aligned. Fixed with the wire group 1 in the aligned state
The pieces 7 are co-wound with a tape winding 12 to set and fix the electric wires to each other.

After that, the protective cap 5 in that state is bent from the fixing piece 7 so that the conductor entrance 10
Then, the front end portion of the electric wire group 1 is taken out of the cap, and the exposed conductor group 2 is mutually welded by the splicing machine 13 of the welding machine to form the splice portion 3. Subsequently, the splice portion 3 is returned from the conductor entrance 10 into the cap body 6, and the protection cap 5 is covered and set on the front end portion of the wire group 1 in a normal posture.

Next, a protective cap 5 according to another embodiment will be described with reference to FIG. That is, in the case of having the same conductor entrance 10 as in the embodiment of FIG. 1, the conductor entrance 10 of FIG. 2 has an edge portion obtained by dividing the peripheral wall of the cap body 6 in the longitudinal direction as shown in FIG. 2A and 2B, a shape obtained by curling inward and elastically contacting, or a shape obtained by overlapping similarly divided edges as shown in FIG. 2B, or a shape shown in FIGS. 2C and 2D. It has a circular window shape or a star window shape perforated on the peripheral wall of the cap body 6. The window-shaped one is bent so that the tip of the wire group 1 is spliced out by bending the cap body 6, and then returned from the window-shaped conductor doorway 10 to be stored. Has become.

1 and 2 has the above-mentioned action, and the exposed conductor group 2 does not shift during splicing and maintains a straightened posture with the leading end. Shape can be made stable and high quality. The end of the exposed conductor group 2 need only be inserted into the cap body 6 and pressed against the abutting portion 8, and the operation is simplified and special attention is not required, and the protective cap 5 is covered from splicing. The series of operations leading to is streamlined.

Next, an embodiment of the protection cap with the electric wire mounting table will be described with reference to FIG. That is, in the protection cap 5 mainly including the “finger-sack” -shaped cap body 6 that covers the splice portion 3 of the electric wire group 1, the flexibility extending in the longitudinal direction of the cap body 6 from the entrance of the cap body 6. A strip slide rail 14 is provided integrally with the cap body 6, and the slide rail 14 is inserted into the rail insertion hole 16 through the slide rail, and has an upper portion formed by an electric wire mounting portion 17. A table 15 is provided. And this electric wire mounting table 15 is a slide rail 1
4 and has a slide stroke approximately two to three times the total length of the cap body 6.

The protective cap 5 has the same abutting portion 8 as in the embodiment of FIG. 1, and a female locking portion 19 provided on the slide rail 14 and a male locking portion protruding from the lower surface of the electric wire mounting table 15. The cap body 6 is retracted below the electric wire mounting table 15, and the slide rail 14 is bent so that the cap body 6 can be removably locked by the locking mechanism. it can.

The above-mentioned protective cap 5 with an electric wire mounting table is
It is covered with the splice part 3 of the electric wire group 1 by the following procedure / method. That is, (see FIG. 3 (B)), first, the electric wire mounting table 15 is positioned substantially in the middle of the slide rail 14, and
Set on the bearing jig 20 together with the cap body 6,
The electric wire group 1 is put into the cap body 6, abuts against the abutting portion 8, the ends thereof are aligned, and the electric wire group 1 is placed on the electric wire mounting table 15 and shaped and set. Then, the wire group 1 in the shaping setting posture is fixed to the wire mounting table by the tape winding 12.

Thereafter, the wire mounting table 15 in the set and fixed state is slid to move the exposed conductor group 2 at the tip out of the cap body 6, and the slide rail 14 is bent and locked by the locking mechanism. The cap body 6 is held in a state of being retracted from the tip of the wire group 1. Subsequently, the exposed conductor 2 protruding in this state is welded and connected by the splicing machine 13 to form the splice portion 3. Thereafter, the locking mechanism is loosened and the cap body 6 is moved forward of the wire group 1. Then, the electric wire mounting table 15 is slid forward and the splice portion 3 is stored in the cap body 6.

Then, the electric wire group 1 and the slide rail 14 in this state are fixed by a tape winding 12, and the protective cap 5 is set on the splice portion 3 in a normal posture.
The embodiment of FIG. 3 has the same operation as that of the embodiment of FIG. 1 and has the above-mentioned locking mechanism, so that the cap body 6 does not hinder the splicing process, and It becomes extremely easy.

The protective cap 5 of the present invention is made of resin or rubber. The locking mechanism of the bending posture of the slide rail 14 in the embodiment of FIG. 3 may be omitted.
