のである。 Fig. 2 shows an embodiment of the present invention, in which a spindle-shaped structure made of aluminum or the like is supported by the main cable 1 and the branch cables 2, 2, and covers the connection part 3 of both cables 1, 2. A protective tube 8 is provided, and a heat-shrinkable sleeve 7 is provided in close contact with the protective tube 8 so as to integrally cover the protective tube 8 and a portion of the cables 1 and 2 on both sides of the protective tube 8. That is, the protective tube 8 has reduced diameter portions 9, 9, which have tapered outer diameters at both ends thereof. Further, a large number of slits 10 are provided at the ends of these reduced diameter portions 9, 9, which open at these ends and reach halfway in the axial direction of the reduced diameter portions 9. The slits 10 are narrow at the proximal end and gradually widen toward the open end, and the parts divided into many parts by the slits 10 can be bent in the radial direction. The protective tube support piece 11... The protective tube 8 is, for example, as shown in FIG.

リーブ７が保護されることになる。 Such a protection structure for the connection part can be achieved by bending the protection tube support pieces 11 . Connect the protection tube 8 to the cables 1 and 2 by easily matching the inner diameter of the end to the outer diameter of the cables 1 and 2.
2 can be supported. Therefore, it is easy to apply regardless of the outer diameter of the cable to be connected. In addition, by forming the slits 10 up to the middle of the reduced diameter parts 9, the protection tube support pieces 11 are bent from the middle of the slope of the reduced diameter part 9, so the bending angle is small. It can be suppressed. In FIG. 4, in order to bring the tip of the protection tube support piece 11 into contact with the outer surface of the cable 1, the protection tube support piece 11 is attached to the straight pipe part of the protection tube 8 (the part other than the reduced diameter parts 9, 9). If it is necessary to tilt the angle θ 1 , the reduced diameter part 9
is tapered in advance at an angle θ 2 , the protective tube support piece 11 has an angle (θ 1 −
It is only necessary to bend it by θ 2 ). Therefore, since the corner formed on the outer surface side of the proximal end A is unlikely to become sharp, a phenomenon in which, for example, this corner digs into the inner surface of the heat-shrinkable sleeve 7 is suppressed, and as a result, the heat-shrinkable sleeve 7 will be protected.

ることができる。 As explained above, according to the present invention, in the protection structure for the cable connection part, the protective tube is provided to cover the connection part of the cable, and the heat-shrinkable sleeve is provided in close contact with the protection tube to cover the protection tube. A reduced diameter part is provided at both ends of the protection tube, and the outer diameter thereof is tapered, and a diameter reduced part is provided at the end of the reduced diameter part so that the inner diameter of the end of the reduced diameter part can match the outer diameter of the cable. Since a large number of slits are provided that open and reach partway through the reduced diameter section, the following effects can be obtained.

ことができかつ設置作業性が向上する。 By bending in the radial direction the part (protection tube support piece) that is divided into many parts in the circumferential direction by the slits, the outer diameter of both ends of the protection tube can be easily matched to the outer diameter of the cable. Since it can be fixed to cables, it can be applied to various cable connections, and installation workability is improved.

できる。 Since the slit is provided partway through the reduced diameter portion, the bending angle of the protective tube support piece can be made small and damage to the heat-shrinkable sleeve can be suppressed. Therefore, a protective structure for the cable connection portion with high sealing reliability can be obtained.
