Is done. As such a power cable connecting portion and a power cable connecting method, for example, one described in Patent Document 1 is known.
As shown in FIGS. 7 and 8, the power cable connecting portion and the power cable connecting method using the compression sleeve are covered with a conductor cover 122, and the compression sleeve 121 and the conductor are covered. There is one in which the cover 122 is connected by conductive wirings 123 and 123.

In FIG. 7, the power cable 100 includes a cable conductor 101 and a cable insulator 102 covering the cable conductor 101. Similarly, the power cable 110 includes a cable conductor 111 and a cable insulator 112.
When connecting the two power cables 100 and 110, the cable insulators 102 and 112 at the ends of the power cables 100 and 110 are peeled off, and the cable conductors 101 and 111 are exposed. Reference numerals 103 and 113 denote conductor end portions as exposed end portions of the cable conductors 101 and 111, respectively.

  The connection portion 120 of the two power cables 100 and 110 includes a cylindrical compression sleeve 121 that is compressed and connected to the conductor ends 103 and 113 of the power cables 100 and 110, and a radially outer side of the compression sleeve 121. And a pre-molded rubber-integrated insulating cylinder (hereinafter simply referred to as “insulating cylinder”) 124 that covers the ends of the cable insulators 102 and 112 and the conductor cover 122. The insulating cylinder 124 includes a rubber-made inner semiconductive layer 126, an insulating layer 127, and an outer semiconductive layer 128 that are formed in order from the inside.

JP 2002-27651 A

  In FIG. 8, in the compression sleeve 121, it is necessary to leave a portion that is not compressed by the length LA in the axial direction of the compression sleeve 121 in order to connect the conductive wiring 123 to the outer peripheral surface with the screw 129. Therefore, the length of the compression connection portion in the axial direction between the cable conductors 101 and 111 and the compression sleeve 121 is shortened, and the contact area between the cable conductors 101 and 111 and the compression sleeve 121 is reduced. For this reason, it is necessary to lengthen the compression sleeve 121 in order to secure a contact area for forming a sufficient electric conduction path.

In particular, when the cable conductors 101 and 111 are made of aluminum or an aluminum alloy, compared to the case where the cable conductors 101 and 111 are made of copper or a copper alloy, oxidation and contact of the compression connection portions of the cable conductors 101 and 111 are made. The pressure drop tends to proceed, and in order to cope with this problem, it is necessary to increase the contact area, so that the compression sleeve 121 becomes longer.
That is, the contact resistance is easily increased by an oxide film formed on the surface of the cable conductors 101 and 111 made of aluminum or aluminum alloy by oxidation. Moreover, the creep phenomenon easily occurs in aluminum, and when the contact pressure per unit area becomes excessive, the contact pressure between the cable conductors 101 and 111 and the compression sleeve 121 gradually decreases, and the contact resistance easily increases. From the above, it is necessary to increase the contact area by increasing the length of the compression connection portion between the cable conductors 101 and 111 and the compression sleeve 121. For this reason, a longer compression sleeve 121 is required.
Further, since the conductive wiring 123 is attached to the compression sleeve 121 with the screw 129, the connection process of the power cables 100 and 110 becomes complicated, and the number of parts increases, so that the connection portion is simplified and connected. Simplification of the process is desired.

  The present invention has been made in view of the above-described circumstances, and it is possible to reduce the contact resistance by lengthening the compression connection portion between the cable conductor and the compression sleeve while avoiding the lengthening of the compression sleeve. Also, it is an object of the present invention to provide a power cable connection portion and a power cable connection method capable of simplifying the connection portion of the power cable and simplifying the connection process.

  In order to solve the above-described problems, the present invention compresses and connects cable conductors of a power cable with a compression sleeve, covers the compression sleeve with a conductor cover, and connects the conductor cover and the compression sleeve with a conductive wiring. In the connection portion of the power cable, the conductive wiring is compression-connected between the compression sleeve and the cable conductor.

According to the connecting portion of the power cable having such a configuration, there is no need to provide a portion for connecting the conductive wiring to the outer peripheral surface of the compression sleeve, and the entire compression sleeve can be compressed in the axial direction. By utilizing the whole, the contact area with the cable conductor can be increased to reduce the contact resistance. Therefore, sufficient electrical conduction between the compression sleeve and the cable conductor can be ensured.
In addition, since the conductive wiring is connected between the compression sleeve and the cable conductor using the compressive force at the time of the compression connection, a tool, a fastening member for the conductive wiring, and a fastening work are required when connecting the conductive wiring. It is not necessary, and simplification of the connecting portion of the power cable and simplification of the connecting process can be achieved.

The said structure WHEREIN: The said electroconductive wiring may have thickness which can be inserted between the said compression sleeve and the said cable conductor. According to the connecting portion of the power cable having such a configuration, the conductive wiring can be easily inserted between the compression sleeve and the cable conductor.
Further, in the above configuration, a gap for drawing out the conductive wiring may be provided between the compression sleeve and the cable insulator. According to the connecting portion of the power cable having such a configuration, the compression sleeve can be compressed in the entire axial direction while preventing the compression sleeve from coming into contact with the cable insulator. Further, the conductive wiring can be pulled out from the gap and easily connected to the conductor cover.

  Further, in the above configuration, the cable conductor may be made of aluminum or an aluminum alloy. According to the connecting portion of the power cable having such a configuration, the contact area between the compression sleeve and the cable conductor can be increased. Therefore, even if the cable conductor is made of aluminum or aluminum alloy, the cable conductor and the compression sleeve The contact pressure per unit area of the cable can be lowered to suppress the creep phenomenon, and the contact resistance between the compression sleeve and the cable conductor can be kept small, and electrical conduction between the compression sleeve and the cable conductor can be ensured for a long period of time. can do.

  The present invention also provides a power cable connection method in which cable conductors of a power cable are compressed and connected with a compression sleeve, the compression sleeve is covered with a conductor cover, and the conductor cover and the compression sleeve are connected with conductive wiring. The conductive wiring is compression-connected between the compression sleeve and the cable conductor.

According to the power cable connection method having such a configuration, there is no need to provide a portion for connecting the conductive wiring to the outer peripheral surface of the compression sleeve, and the entire compression sleeve in the axial direction can be compressed. The contact area between the cable conductor and the cable conductor can be increased to reduce the contact resistance. Therefore, sufficient electrical conduction between the compression sleeve and the cable conductor can be ensured.
In addition, since the conductive wiring is connected between the compression sleeve and the cable conductor using the compression force at the time of compression connection, a tool, a fastening member of the conductive wiring, and a fastening work are required when connecting the conductive wiring. It is not necessary, and simplification of the connecting portion of the power cable and simplification of the connecting process can be achieved.

In the present invention, since the conductive wiring is compression-connected between the compression sleeve and the cable conductor, there is no need to provide a portion for connecting the conductive wiring to the outer peripheral surface of the compression sleeve, and the entire axial direction of the compression sleeve is not provided. The contact resistance between the compression sleeve and the cable conductor can be increased to reduce the contact resistance. Therefore, sufficient electrical conduction between the compression sleeve and the cable conductor can be ensured while suppressing the lengthening of the compression sleeve.
In addition, since the conductive wiring is connected between the compression sleeve and the cable conductor using the compressive force at the time of the compression connection, a tool, a fastening member for the conductive wiring, and a fastening work are required when connecting the conductive wiring. It is not necessary, and simplification of the connecting portion of the power cable and simplification of the connecting process can be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, each of the two power cables 11 and 12 includes a cable conductor 13 formed of a stranded wire formed by twisting a plurality of strands, and a cable insulator 14 covering the cable conductor 13. Consists of The end of the cable insulator 14 is stripped off, and the cable conductor 13 is exposed. Reference numeral 13 a denotes a conductor end portion of the cable conductor 13 protruding from the cable insulator 14.

  The connecting portion 20 is a cylindrical compression sleeve 21A that is compressed from the radially outer side to the inner side by the conductor end portions 13a, 13a of the power cables 11, 12, and a metal that covers the radially outer side of the compression sleeve 21A. Conductor cover 22, compression sleeve 21 </ b> A (and cable conductors 13, 13), and a plurality of conductive wires 23 that electrically connect conductor cover 22, cable insulators 14 and conductor covers of power cables 11, 12. 22 (see FIG. 7).

The cable conductor 13 of the power cables 11 and 12 is made of aluminum or an aluminum alloy.
As for the cable insulator 14, the fitting part 14a in which the edge part of the conductor cover 22 is fitted over the perimeter is formed in the edge part. The fitting portion 14a includes a small-diameter portion 14b formed on the end face side of the cable insulator 14, and an annular groove 14c adjacent to the small-diameter portion 14b and having a groove bottom formed with a smaller diameter than the small-diameter portion 14b. ing.

  The compression sleeve 21A has an outer peripheral surface 21b that is compressed in its entirety in the axial direction from the radially outer side to the inner side and reduced in diameter, and is compressed and connected to the conductor end portions 13a of the cable conductors 13 and 13 so as to be electrically conductive. It is fixed to. The axial direction of the compression sleeve 21A described above is the direction in which the axis of the compression sleeve 21A extends. The material of the compression sleeve 21A is aluminum or aluminum alloy which is the same material as the cable conductors 13 of the power cables 11 and 12. Thus, by making the material of the compression sleeve 21A the same as the material of the cable conductor 13, the occurrence of corrosion between different metals at the compression connection portion between the cable conductor 13 and the compression sleeve 21A is suppressed, and for a long time. This makes it easier to ensure electrical conduction.

  The conductor cover 22 is composed of two metal cylinder halves 26 and 26 formed by dividing the cylinder in half along the axial direction. At both ends of the cylindrical half 26, there are formed inner projecting walls 26a and 26a that project inward in the radial direction and are formed on the entire half circumference. These inner projecting walls 26 a and 26 a are fitted in the annular groove 14 c of the cable insulator 14. Further, the cylindrical half body 26 is formed with a plurality of female screws 26b penetrating the inner peripheral surface and the outer peripheral surface thereof.

  The conductive wiring 23 is composed of a braided wire. One end portion of the conductive wiring 23 is not subjected to terminal treatment, and the other end portion is crimp-bonded to a crimp terminal 27. Since one end portion of the conductive wiring 23 is fixed by a compressive force that compresses the cable conductor 13 with the compression sleeve 21A, attachment of a connection tool such as a connection terminal to one end portion, or one end portion is fastened to the compression sleeve 21A side. There is no need for fasteners such as screws.

  The crimp terminal 27 attached to the other end of the conductive wiring 23 is attached to the inner peripheral surface of the conductor cover 22 with a screw 28 screwed into the female screw 26b, and is electrically connected. In the present embodiment, since the conductive wiring 23 is formed of a braided wire, the braided wire can be freely deformed, and the connection work between the compression sleeve 21A and the conductor cover 22 can be easily performed. Thus, by connecting the cable conductors 13 and 13 and the compression sleeve 21A and the conductor cover 22 by the conductive wiring 23, the conductor cover 22 is set to the same potential as the cable conductor 13, and a spark is generated between them. To suppress.

Next, the outline of this connection method will be described with reference to FIG.
In order to form the connecting portion 20, first, the conductor end portions 13 a and 13 a of the power cables 11 and 12 are inserted into a cylindrical compression sleeve 21 before compression as indicated by white arrows A and A.
Thereafter, as will be described later, the compression sleeve 21 is compressed, the conductive wiring 23 is attached, and the cylindrical halves 26 and 26 to be the conductor cover 22 are covered on the compression sleeve 21 from the outside as indicated by the white arrows B and B. .
For the convenience of explanation, the compression sleeve 21A (see FIG. 1) before compression is referred to as the compression sleeve 21, and is identified by changing the sign before and after compression.

FIG. 3 shows a temporary assembly of the compression sleeve 21 and the conductive wiring 23 to the conductor end 13 a of the power cable 11. Here, the temporary assembly is distinguished from the actual assembly in which the compression sleeve 21 and the conductive wiring 23 are finally compressed and fixed as shown in FIG. (Same below).
One end of each of the conductive wirings 23 and 23 is formed flat and bent at a substantially right angle to form a bent portion 23a. The bent portion 23a is directed toward the compression sleeve 21 and is compressed as shown by an arrow C. 21 is inserted inside.

Next, in a state where the bent portion 23a of the conductive wiring 23 is inserted into the compression sleeve 21, the conductive ends 23a and 23 and the compression sleeve 21 are connected to the conductor end 13a of the power cable 11 as indicated by arrows D and D. Put on. At this time, the bent portions 23a and 23a of the conductive wiring 23 are disposed between the conductor end portion 13a and the compression sleeve 21 (see FIG. 4).
First, the bent portions 23a, 23a of the conductive wirings 23, 23 are disposed on the surface of the conductor end portion 13a of the power cable 11, and thereafter, the conductor end portion 13a and the bent portions 23a, 23a are covered with the compression sleeve 21. May be placed in the compression sleeve 21.

  As shown in FIG. 4, following the power cable 11, also for the power cable 12, the conductor end portion 13 a and the bent portions 23 a and 23 a of the conductive wirings 23 and 23 are inserted into the compression sleeve 21, and the conductor end portion 13 a Bending portions 23 a and 23 a of the conductive wirings 23 and 23 are arranged between the compression sleeve 21. The conductor ends 13a and 13a of the power cables 11 and 12 are inserted into the compression sleeve 21 until they substantially abut each other.

  Before the compression sleeve 21 is compressed, the outer peripheral surface of the conductor end 13a and the inner peripheral surface of the compression sleeve 21 have a gap 31 that is separated by a distance C1 in the radial direction. The bent portion 23 a of the conductive wiring 23 is formed to a thickness that can be inserted into the gap 31. Further, a gap 32 is provided between the end face of each cable insulator 14 of the power cables 11 and 12 and the end face of the compression sleeve 21 by a distance C2 in the axial direction of the compression sleeve 21.

  The gap 32 is a portion for drawing out the conductive wiring 23 from between the cable insulator 14 and the compression sleeve 21, and the crimp terminal 27 of the conductive wiring 23 is attached to the conductor cover 22 (see FIG. 1) through this gap 32. At this time, the movable range of the conductive wiring 23 can be widened, and the mounting work is facilitated. This completes the temporary assembly of the connecting portion. In the present embodiment, the bent portion 23a, which is one end portion of the conductive wiring 23, remains as a braided wire, and is simply inserted between the conductor end portion 13a and the compression sleeve 21, thereby connecting the connection portion 20 ( The structure of FIG. 1) is simplified, and the connection process is simplified.

After the temporary assembly, as shown in FIG. 4, a hexagonal compression die 34 used for compression of the compression sleeve 21 is disposed. The hexagon compression die 34 is composed of a pair of dies 35, 36, and the length L1 of the pressing portion of the hexagon compression die 34 is longer than the total length L with respect to the axial total length L of the compression sleeve 21, thereby compressing. The entire axial direction of the sleeve 21 can be compressed.
Thus, even if the length L1 of the pressing portion of the hexagonal compression die 34 is longer than the total length L of the compression sleeve 21, the compression sleeve by the hexagonal compression die 34 is provided by providing the gaps 32, 32 on both sides of the compression sleeve 21. Even during the compression stroke 21, the conductive wiring 23 can be separated at a position that does not interfere with the hexagonal compression die 34.

FIG. 5 shows a state of the compression sleeve 21 before compression.
The dies 35 and 36 of the hexagonal compression die 34 are provided with concave pressing portions 35a and 36a each having a half-section of a hexagonal hole. The pressing portion 35a includes a bottom surface 35c and slopes 35d and 35e adjacent to both sides of the bottom surface 35c. Similarly, the pressing portion 36a includes a bottom surface 36c and slopes 36d and 36e adjacent to both sides of the bottom surface 36c.
As indicated by the white arrow, the die 35 is moved onto the die 36 by a press or the like, so that the conductor end portion 13a having a substantially circular cross section and the cylindrical compression sleeve 21 are bent portions of the conductive wirings 23 and 23. It compresses with 23a and 23a.

  The bent portions 23a, 23a of the conductive wirings 23, 23 are positioned so as to face the pressing portions 35a, 36a of the dies 35, 36, preferably, positions facing the bottom surfaces 35c, 36c of the pressing portions 35a, 36a. The conductor end 13a and the compression sleeve 21 are inserted into the gap 31. By inserting in such a position, it is possible to easily transmit the compressive force to the bent portions 23a and 23a via the compression sleeve 21 by the bottom surfaces 35c and 36c substantially orthogonal to the moving direction of the die 35. It can fix more reliably between the edge part 13a and the compression sleeve 21. FIG.

FIG. 6 shows a state after compression of the compression sleeve 21.
The die 35 moves onto the die 36, and the conductor end 13a, the compression sleeve 21A, and the conductive wirings 23 and 23 are compression-connected. In addition, the bent portions 23a of the conductive wirings 23 and 23 are sandwiched and fixed between the conductor end portion 13a and the compression sleeve 21A. That is, the conductor end 13a and the compression sleeve 21A, and the conductor end 13a and the conductive wirings 23 and 23 are mechanically and electrically connected to each other.

  Thereafter, crimp terminals 27 (see FIG. 4) at the other end portions of the conductive wirings 23, 23 are provided on the inner peripheral surface of each cylindrical half body 26 of the conductor cover 22 shown in FIG. 2 with screws 28 (see FIG. 1). As shown in FIG. 1, the cylinder halves 26 are fitted into the cable insulators 14 of the power cables 11 and 12, and the outer side of the compression sleeve 21 </ b> A is covered with the conductor cover 22. Then, the insulating cylinder 124 (see FIG. 7) previously placed on one of the power cables 11 and 12 is moved so as to straddle each cable insulator 14 and the conductor cover 22 of the power cables 11 and 12, and further, the insulating cylinder The connection process is completed by performing shielding processing and protective tube assembly outside 124.

  In the embodiment described above, the cable conductors 13 and 13 of the power cables 11 and 12 are compression-connected with the compression sleeve 21A, the compression sleeve 21A is covered with the conductor cover 22, and the conductor cover 22 and the compression sleeve 21A are electrically conductive. The conductive wiring 23 is compression-connected between the compression sleeve 21 </ b> A and the cable conductor 13 at the connection portion 20 of the power cables 11 and 12 connected by the conductive wiring 23.

  According to this configuration, the entire axial direction of the compression sleeve 21A can be compressed, and the entire compression sleeve 21A can be effectively used to increase the contact area with the cable conductor 13 and reduce the contact resistance. it can. Therefore, even if the compression sleeve 21A is shortened, sufficient electric conduction with the cable conductor 13 can be ensured. In addition, since the conductive wiring 23 is connected at the same time when the compression sleeve 21A and the cable conductor 13 are compression-connected, there is no need for a fastening member or a tool to attach the conductive wiring 23 to the compression sleeve 21A, and the power cable 11 , 12 can be simplified and the connection process can be simplified.

Further, as shown in FIGS. 3 and 4, the conductive wiring 23 has a thickness that can be inserted between the compression sleeve 21 and the cable conductor 13. The insertion operation of the conductive wiring 23 can be easily performed.
In addition, since there is a gap 32 between the compression sleeve 21A and the cable insulator 14 for drawing out the conductive wiring 23, the compression sleeve 21 is prevented from coming into contact with the cable insulator 14 and the compression sleeve 21 is moved in the entire axial direction. Can be compressed. Further, the conductive wiring 23 can be pulled out from the gap 32 and can be easily connected to the conductor cover 22.

Since the cable conductors 13 of the cables 11 and 12 connected in the above embodiment are made of aluminum or an aluminum alloy, the cable conductor 13 is compressed and connected to the compression sleeve 21A due to the influence of the oxide film as compared with the case where the conductor is made of copper. Contact resistance tends to increase. Also, the contact resistance tends to gradually increase due to the influence of the decrease in contact pressure over time due to the creep phenomenon.
On the other hand, in this embodiment, since the conductive wiring 23 is compressed and connected between the compression sleeve 21A and the cable conductor 13, the entire compression sleeve 21 can be compressed to connect the cable conductors 13 and 13. It was. As a result, by effectively utilizing the entire length of the compression sleeve 21A and increasing the length of the compression connection portion, the contact area between the cable conductor 13 and the compression sleeve 21A can be further increased without increasing the length of the compression sleeve 21 itself. It was big. Moreover, it was possible to avoid an excessive contact pressure per unit area. As a result, the above-described contact resistance can be further reduced and the state can be maintained for a long time. Therefore, electrical conduction between the compression sleeve 21A and the cable conductor 13 can be ensured over a long period of time.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.
For example, in the above embodiment, as shown in FIG. 1, the cable conductor 13 of the power cables 11 and 12 is made of aluminum or an aluminum alloy, but is not limited thereto, and may be made of copper or a copper alloy. Further, although the compression sleeve 21A is made of aluminum or aluminum alloy made of the same material as the cable conductor 13, the present invention is not limited to this, and when the cable conductor 13 is made of copper or copper alloy, the compression sleeve 21A is made of copper or the same material. A copper alloy may be used.

  Further, as shown in FIG. 3, the conductive wiring 23 is linear, but not limited to this, the conductive wiring is an annular shape sandwiched between the conductor end 13 a and the compression sleeve 21. And a plurality of linear portions extending from the annular portion, and the ends of the linear portions may be connected to the conductor cover 22 (see FIG. 1). By forming the annular portion in the conductive wiring in this way, the annular portion can be easily fitted to the conductor end portion 13a, and the conductive wiring and the compression sleeve 21 can be easily temporarily assembled to the conductor end portion 13a. Can do.

In addition, one end portion of the conductive wiring 23 is bent to form the bent portion 23a. However, the present invention is not limited to this, and the one end portion of the conductive wiring 23a can be easily inserted between the conductor end portion 13a and the compression sleeve 21. It may be simply curved. Alternatively, one end of the conductive wiring 23a may be inserted as it is without being specifically bent or curved.
