(First embodiment)
FIG. 1 is a plan view of a sleeve member according to the first embodiment. FIG. 2 is a cross-sectional view taken along the line II-II ′ of FIG. 3 is a cross-sectional view taken along the line III-III ′ of FIG. 1 and viewed from the direction of the arrow. The sleeve member 10 of the embodiment is a member for butting two electric wires and electrically connecting them, and in particular, can be used for an electric wire connecting operation in an indirect hot wire method for performing an operation without a power failure.

  As shown in FIGS. 1 and 2, the sleeve member 10 of the present embodiment includes a first tubular portion 11 and a second tubular portion 12. The first cylindrical portion 11 and the second cylindrical portion 12 are metal cylindrical members, respectively, and are integrally connected in the axial direction. The first hole portion 21 of the first tubular portion 11 opens on one end side of the sleeve member 10, and the second hole portion 22 of the second tubular portion 12 opens on the other end side of the sleeve member 10.

  A stopper 14 is provided at the center of the sleeve member 10 in the direction of the central axis AX. The stopper 14 protrudes from the inner peripheral surface 15a of the sleeve member 10 toward the central axis AX. The first cylindrical portion 11 and the second cylindrical portion 12 are separated by a stopper 14 at a location indicated by a one-dot chain line A in FIGS. The electric wires inserted into the first cylindrical portion 11 and the second cylindrical portion 12 are in contact with the stopper 14 and the insertion position in the axial direction is determined. A plurality of stoppers 14 are provided along the circumferential direction, but at least one stopper may be provided. The stopper 14 may have a wall shape that partitions the first cylindrical portion 11 and the second cylindrical portion 12.

  The first cylindrical portion 11 is provided with a protruding portion 24 that protrudes from the inner peripheral surface 15a to the inner space side. The protrusion 24 extends in a direction from the end side of the first cylindrical portion 11 toward the stopper 14 and protrudes so as to approach the central axis AX. As shown in FIG. 1, the 1st cylindrical part 11 is provided with the two cuts 27b extended in the direction along the center-axis AX direction, and the cut 27a extended in the direction along the circumferential direction. The protruding portion 24 is formed by cutting a part of the first cylindrical portion 11 at the notches 27a and 27b and bending it toward the inner space side at the bent portion 27c. Therefore, a structure for attaching another member for temporarily fixing the electric wire is not required, and the electric wire can be temporarily fixed with a simple configuration.

  As shown in FIG. 2, the protruding portion 24 includes a first surface 24 b facing the inner space of the first tubular portion 11 and a second surface 24 c facing the extending direction of the protruding portion 24. The first surface 24b and the second surface 24c are connected with an angle of about 90 °. The edge part 24a of the protrusion part 24 is comprised by the part to which the 1st surface 24b and the 2nd surface 24c were connected. When the edge part 24a of the protrusion part 24 contacts the electric wire inserted in the 1st cylindrical part 11, a removal prevention of an electric wire is performed. The first surface 24b and the second surface 24c are connected at about 90 °, but may be connected at an angle smaller than 90 ° or may be connected at an angle larger than 90 °. .

  A compressed display line 16 is provided on the outer periphery of the first cylindrical portion 11 and the second cylindrical portion 12. A plurality of compressed display lines 16 are displayed in a direction along the central axis AX direction. With the electric wire inserted into the first cylindrical portion 11 and the second cylindrical portion 12, the first cylindrical portion 11 and the second cylindrical portion 12 are compressed at the position of the compression display line 16 using a compression tool. As a result, the electric wire is fixed to the sleeve member 10. A sealing compound (not shown) is provided in the internal space of the first tubular portion 11 and the second tubular portion 12, and the first tubular portion 11 and the second tubular portion 12 are compressed. The space between the electric wire and the inner peripheral surface 15a is sealed.

  Further, the first cylindrical portion 11 is provided with a slit portion 25. The slit portion 25 penetrates the inner peripheral surface 15a and the outer peripheral surface 15b of the first tubular portion 11, and extends in the direction along the central axis AX direction as a whole. The slit part 25 and the protrusion part 24 are provided in the edge part side of the 1st cylindrical part 11, ie, the opening vicinity of the 1st hole part 21 in which an electric wire is inserted. The slit portion 25 is provided with a gap from the protruding portion 24 in the circumferential direction of the first tubular portion 11. As shown in FIG. 3, two slit portions 25 are provided at intervals in the circumferential direction of the first cylindrical portion 11. The two slit portions 25 are provided symmetrically about a line passing through the central axis AX as an axis of symmetry. The protruding portion 24 is provided in a direction intersecting with the direction connecting the slit portions 25, 25. Although two slit portions 25 are provided, three or more slit portions 25 may be provided, or at least one slit portion 25 may be provided.

  By providing the slit portion 25 in this manner, by applying a compressive stress to the first cylindrical portion 11 in the vertical direction of FIG. 3, the first cylindrical portion 11 is easily compressed and deformed radially inward in the vertical direction. . Further, the protruding portion 24 and the slit portion 25 are provided on the end portion side of the first cylindrical portion 11 and are provided with a space therebetween in the circumferential direction of the first cylindrical portion 11. That is, it is provided so that at least a part of the protruding portion 24 overlaps the range of the slit portion 25 in the length direction. As will be described later, since the protruding portion 24 is elastically deformed with the compression deformation of the first cylindrical portion 11 and the electric wire is prevented from coming off, the electric wire can be easily pulled out even after temporary fixing. .

  As shown in FIG. 2, in the present embodiment, the slit portion 25 includes an extending portion 25a and a bent portion 25b. The extending portion 25 a extends in a direction inclined with respect to the central axis AX direction of the first cylindrical portion 11, and one end side of the extending portion 25 a continues to the end portion of the first cylindrical portion 11. Provided. By doing so, the first cylindrical portion 11 is easily deformed. Therefore, even when the diameter of the first cylindrical portion 11 is large or the thickness is thick, the end portion of the first cylindrical portion 11 is used. On the side, it can be easily compressed and deformed radially inward.

  The bent portion 25b is provided on the other end side of the extending portion 25a, and is bent toward the outer side in the width direction of the extending portion 25a. The inner wall of the bent portion 25b is connected at an acute angle to form a tip edge portion 25c. Here, “acute angle” means that the angle formed between the inner walls of the bent portion 25b when viewed from the side is smaller than 90 °. Note that the edge portion 25c may have an angle of 90 ° or more. Further, the bent portion 25b may have a curved shape. By providing the bent portion 25b in this way, when compressive stress is applied to the first tubular portion 11, the first tubular portion 11 is deformed starting from the edge portion 25c. Therefore, the variation of the deformation | transformation to the radial inside of the 1st cylindrical part 11 can be suppressed.

  Further, the bent portion 25 b is provided at a position farther from the end of the first cylindrical portion 11 than the protruding portion 24. In other words, the bent portion 25 b is provided closer to the center side of the sleeve member 10 in the direction of the central axis AX than the protruding portion 24. For this reason, since the first cylindrical portion 11 is compressively deformed at the end portion side of the edge portion 25c and provided with the protruding portion 24, the protruding portion 24 is elastically deformed and the temporary fixing of the electric wire is released. Is done.

  The extending portion 25 a of the slit portion 25 extends in a direction inclined with respect to the central axis AX direction of the first tubular portion 11. Specifically, the extending part 25 a is inclined in a direction away from the projecting part 24 toward the end of the first cylindrical part 11. As a result, in the first cylindrical portion 11 separated in the circumferential direction by the extending portion 25a, the portion provided with the protruding portion 24 is easily deformed, and the protruding portion 24 is elastically deformed without fail to temporarily deform the electric wire. It can be released. The shape of the slit portion 25 may be variously changed. For example, the extension portion 25a may extend in a direction along the central axis AX direction.

  In this embodiment, the 1st cylindrical part 11, the 2nd cylindrical part 12, and the protrusion part 24 use metal materials, such as copper alloys, such as brass, and an aluminum alloy. The sleeve member 10 can be manufactured by preparing one cylindrical member and processing the stopper 14, the protruding portion 24, and the slit portion 25.

  Next, with reference to FIGS. 4 to 6, a method for temporarily fixing the electric wire of the sleeve member 10 of the present embodiment will be described. FIG. 4 is a cross-sectional view for explaining a method of temporarily fixing the first electric wire to the sleeve member. FIG. 5 is a cross-sectional view illustrating a state where the first electric wire is temporarily fixed to the sleeve member. FIG. 6 is a cross-sectional view illustrating a state where the second electric wire is inserted into the sleeve member.

  As shown in FIG. 4, the 1st electric wire 100 has the core material 100a, such as a copper wire, and the insulating coating layer 100b which coat | covers the core material 100a. At the end of the first electric wire 100, the core material 100a is exposed from the coating layer 100b. The exposed core material 100a is inserted into the first hole portion 21 of the first cylindrical portion 11. The core member 100a is inserted along the inner peripheral surface 15a in the direction indicated by the arrow B in FIG. At this time, the protruding portion 24 is deformed along the core material 100a as the core material 100a is inserted, so that the core material 100a can be easily inserted into the first cylindrical portion 11.

  Next, as shown in FIG. 5, the leading end of the core material 100 a comes into contact with the stopper 14, and the insertion of the first electric wire 100 is completed. At this time, a slight gap 31 is provided between the core material 100a and the first cylindrical portion 11. When the insertion of the first electric wire 100 is completed, the protruding portion 24 is elastically deformed so as to return to the original shape, and the edge portion 24a of the protruding portion 24 comes into contact with the core material 100a. In this state, even if an external force is applied to the first electric wire 100 in the direction indicated by the arrow C in FIG. 5, it is difficult to pull out the first electric wire 100 because the protruding portion 24 is in contact. Become. As described above, the protrusion 24 prevents the first electric wire 100 from coming off, and the first electric wire 100 is temporarily fixed to the sleeve member 10.

  After the first electric wire 100 is temporarily fixed to the first tubular portion 11, the second electric wire 101 is inserted into the second hole portion 22 of the second tubular portion 12 as shown in FIG. 6. The 2nd electric wire 101 has core material 101a, such as a copper wire, and insulating coating layer 101b which coats core material 101a. The core material 101a exposed from the coating layer 101b is inserted into the second cylindrical portion 12. Since the 1st electric wire 100 is temporarily fixed to the 1st cylindrical part 11 at this time, it is not necessary to support by indirect hot wire tools, such as a hot stick, and can insert the 2nd electric wire 101 easily. . Then, the core material 101a comes into contact with the stopper 14, and the insertion of the second electric wire 101 is completed. Then, the 1st electric wire 100 and the 2nd electric wire 101 are compression-fixed by compressing the 1st cylindrical part 11 and the 2nd cylindrical part 12 with compression tools, such as pliers. As a result, the first electric wire 100 and the second electric wire 101 are connected via the sleeve member 10.

  As described above, according to the sleeve member 10 of the present embodiment, the protrusion 24 can be reliably contacted and the first electric wire 100 can be temporarily fixed only by inserting the first electric wire 100. Therefore, it is not necessary to temporarily fix the first electric wire 100 by supporting it with an indirect hot wire tool such as a hot stick, so that the compression work after the temporary fixing can be easily performed. Further, as described above, since the protruding portion 24 is provided so as to bend a part of the first cylindrical portion 11, it is necessary to separately provide a temporary fixing structure for the first electric wire 100 in the first cylindrical portion 11. The first electric wire 100 can be temporarily fixed with a simple configuration. Further, even when the size of the gap 31 is different, that is, when the diameter of the core material 100a is different or when the diameter of the first cylindrical portion 11 is different, it is good only by changing the bending angle of the protruding portion 24. In addition, the first electric wire 100 can be temporarily fixed.

  Next, with reference to FIG.7 and FIG.8, the extraction method of the 1st electric wire 100 after temporary fixing is demonstrated. FIG. 7 is a cross-sectional view for explaining a method of pulling out the first electric wire from the sleeve member. FIG. 8 is an enlarged sectional view showing a state in which the sleeve member is compressed and deformed radially inward.

  After the first electric wire 100 is temporarily fixed, when it becomes necessary to pull out the first electric wire 100 from the first cylindrical portion 11, as shown in FIG. The compression stress is applied by sandwiching the portion 11 from above and below. In this case, compressive stress is applied to the first cylindrical portion 11 in the width direction of the slit portion 25. Further, it is preferable that compressive stress is applied at a position overlapping with the protruding portion 24. Note that the compression tool 104 can use, for example, insulating pliers.

  As shown in FIG. 8, when compressive stress is applied in the direction indicated by the arrow D by the compression tool 104, the extension portion 25 a of the slit portion 25 is deformed so that the width thereof is reduced. In addition, in FIG. 8, about the slit part 25, the protrusion part 24, and a part of 1st cylindrical part 11, the state before applying compressive stress is shown with a dotted line, and the state after applying compressive stress is shown with a continuous line. Yes. The first cylindrical portion 11 is deformed radially inward from a location 11a corresponding to the position where the edge portion 25c of the slit portion 25 is provided. By deforming the end side of the first tubular portion 11, the edge portion 24 a of the protruding portion 24 is elastically deformed in a direction away from the core material 100 a of the first electric wire 100. Thereby, since the amount of biting into the core material 100a of the protrusion 24 can be reduced, the first electric wire 100 can be easily pulled out in the direction of the arrow C (see FIG. 7). In this way, the temporary fixing of the first electric wire 100 is released.

  In addition, when releasing temporarily fixing of the 1st electric wire 100, the case where the protrusion part 24 does not elastically deform may be sufficient. In this case, as the first cylindrical portion 11 is deformed, the protruding portion 24 is inclined in the direction along the core material 100a, so that the amount of protrusion of the protruding portion 24 into the core material 100a is reduced and the first electric wire 100 is reduced. Can be pulled out.

  As described above, the sleeve member 10 of the present embodiment is provided integrally with the first cylindrical portion 11 into which the first electric wire 100 is inserted and the first cylindrical portion 11 in the internal space, and the first cylindrical shape. A protruding portion 24 that protrudes from the inner peripheral surface 15a of the portion 11 into the internal space, contacts the first electric wire 100 inserted into the first tubular portion 11 and prevents the first electric wire 100 from coming off, and the first tube And a slit portion 25 penetrating the inner peripheral surface 15a and the outer peripheral surface 15b of the cylindrical portion 11 and having a length in the direction along the axial direction of the first cylindrical portion 11. The protruding portion 24 and the slit portion 25 are provided on the end portion side of the first tubular portion 11 where the first electric wire 100 is inserted, and are spaced from each other in the circumferential direction of the first tubular portion 11. Provided.

  According to this, the structure for temporarily fixing the first electric wire 100 does not need to be provided separately, and the first electric wire 100 can be temporarily fixed with a simple configuration in which the protruding portion 24 is provided. Moreover, since the slit part 25 is provided in the 1st cylindrical part 11, it becomes easy to compress and deform the 1st cylindrical part 11 to radial inside. As the first tubular portion 11 is compressed and deformed, the protruding portion 24 is elastically deformed to release the first electric wire 100, so that the first electric wire 100 can be easily pulled out.

  In the sleeve member 10 of the present embodiment, the slit portion 25 is continuously provided up to the end portion of the first cylindrical portion 11. According to this, even when the diameter of the first cylindrical portion 11 is large or the thickness is thick, it can be easily compressed and deformed radially inward on the end portion side of the first cylindrical portion 11. it can.

  In the sleeve member 10 of the present embodiment, the slit portion 25 extends in a direction along the central axis AX direction of the first cylindrical portion 11 or in a direction inclined with respect to the central axis AX direction of the first cylindrical portion 11. The extension part 25a and the bending part 25b bent toward the outer side of the width direction of the extension part 25a from the inner wall of the extension part 25a are included. According to this, when compressive stress is applied to the inside in the radial direction of the first tubular portion 11, the first tubular portion 11 is compressively deformed starting from the portion 11a where the bent portion 25b is provided. It is possible to easily pull out the first electric wire 100 while suppressing variation in deformation of the one cylindrical portion 11.

  In the sleeve member 10 of the present embodiment, the bent portion 25 b is provided at a position farther from the end portion of the first tubular portion 11 than the protruding portion 24. According to this, since the portion where the protruding portion 24 is provided in the first tubular portion 11 is compressed and deformed starting from the portion 11a where the bent portion 25b is provided, the deformation of the first tubular portion 11 is prevented. Along with this, the edge portion 24 a of the protruding portion 24 is deformed in a direction away from the first electric wire 100. Therefore, it is possible to reliably release the first electric wire 100 from being pulled out by the protruding portion 24.

  In the sleeve member 10 of the present embodiment, a plurality of the slit portions 25 are provided with an interval in the circumferential direction of the first tubular portion 11. According to this, the 1st cylindrical part 11 can be easily compressed and deformed to radial inside.

  In the sleeve member 10 of the present embodiment, the protruding portion 24 protrudes by bending a part of the first cylindrical portion 11 toward the inner space side. According to this, there is no need to provide a separate structure for temporarily fixing the first electric wire 100, and the first electric wire 100 can be temporarily fixed with a simple configuration. Moreover, with the compressive deformation of the first cylindrical portion 11, the protruding portion 24 is elastically deformed, and the temporary fixing of the first electric wire 100 can be easily released.

(Second Embodiment)
FIG. 9 is a plan view of a sleeve member according to the second embodiment. 10 is a cross-sectional view taken along the line XX ′ in FIG. 9 and viewed from the direction of the arrow. In addition, about the structure similar to embodiment mentioned above, the same code | symbol may be attached | subjected and description may be abbreviate | omitted. As shown in FIGS. 9 and 10, the sleeve member 10 </ b> A of the present embodiment is provided with two protrusions 24 and 24. One protrusion 24 is provided above the central axis AX, and the other protrusion 24 is provided below the central axis AX. By providing a plurality of projecting portions 24 and 24 in this manner, the number of contact points between the first electric wire 100 inserted into the first tubular portion 11 and the projecting portions 24 and 24 increases, so that the first electric wire 100 (see FIG. 9 and FIG. 10 (not shown) can be temporarily fixed.

  Further, the slit portion 26 of the present embodiment extends in the direction along the central axis AX and does not reach the end of the first cylindrical portion 11. The slit portion 26 is not provided with the bent portion 25b shown in the first embodiment, and has a substantially rectangular shape. The slit portion 26 is provided so that at least the protruding portions 24 and 24 overlap with each other within the range in the length direction of the slit portion 26. Even in such an aspect, by applying a compressive stress in the vertical direction of FIG. 10 to the first cylindrical portion 11, the width of the slit portion 26 (the length in the circumferential direction of the first cylindrical portion 11). The first cylindrical portion 11 is compressed and deformed radially inward so as to decrease. As the first tubular portion 11 is deformed, the projecting portion 24 is deformed in a direction away from the first electric wire 100, so that the temporary fixing of the first electric wire 100 can be released.

  In this embodiment, since the slit part 26 is provided in the substantially rectangular shape, the process of the slit part 26 is easy. Moreover, since the slit part 26 is not provided to the edge part of the 1st cylindrical part 11, a deformation | transformation is suppressed at the edge part of the 1st cylindrical part 11. FIG. Therefore, since the strength of the sleeve member 10A can be improved compared to the first embodiment, it is possible to select a metal material having a relatively low strength as the sleeve member 10A.

  The sleeve member 10A is provided with the two protrusions 24, 24, but may be provided with three or more protrusions, or may be provided with at least one protrusion. Moreover, the slit part 26 may provide three or more slit parts, or the at least 1 slit part should just be provided.

(Modification)
FIG. 11 is a plan view of a sleeve member according to a modification of the second embodiment. In the sleeve member 10 </ b> B of this modification, the slit portion 26 </ b> A extends in the direction along the central axis AX direction and continues to the end of the first cylindrical portion 11. The position of the slit portion 26 </ b> A in the central axis AX direction overlaps with the protruding portions 24 and 24.

  In this modification, by providing the slit portion 26 </ b> A continuously to the end portion of the first tubular portion 11, the end portion of the first tubular portion 11 is easily deformed. Therefore, even when the diameter of the first cylindrical portion 11 is large or the thickness is large, the first cylindrical portion 11 can be easily compressed and deformed radially inward on the end side of the first cylindrical portion 11. Further, the slit portion 26A can be easily manufactured because the bent portion 25b described above is not provided.

  As mentioned above, although embodiment and modification of this invention were described, this invention is not limited by the content of this embodiment and modification, and can be changed suitably. Furthermore, at least one of various omissions, substitutions, and changes of the components can be made without departing from the gist of the first embodiment and the second embodiment described above.
