Description

  The present invention relates to an edge line connection connector used for connecting edge lines of an aerial distribution line installed on a support such as a utility pole, and an insulating cover used for the edge line connection connector.

  For a retaining pole that connects overhead distribution lines installed from the front and back of the utility pole, a retaining bracket is attached to the armature fixed to the utility pole, and a tension clamp is secured to the tension insulator fixed via the retaining pole from the front and rear of the utility pole. In order to fix the aerial distribution lines via the front and back, and to electrically connect the front and rear aerial distribution lines, edge winding lines drawn from the aerial distribution lines between the front and rear retention clamps (hereinafter referred to as edge lines) Are connected to each other by a connection sleeve.

  As such a connection sleeve, a cylindrical crimp terminal made of a conductive metal having an edge line insertion port at both ends is frequently used, and the core wire exposed by peeling the clothing material at the end of the electric wire to the edge line insertion port is used. By inserting each of them and compressing the connection sleeve using a compression tool in that state, the edge lines are electrically connected to each other (see Patent Documents 1 to 4).

  And the part of the connecting sleeve that connects the edge lines is covered and protected by an insulating member such as an insulating cover (not shown), and in the case where the edge line straddles the armature fixed to the utility pole. The edge line portion shifted from the connection sleeve is secured to the pin lever erected on the arm metal by using a bind line.

However, there is a case where such an edge line is cut and cut off in the middle and then connected again, and when such an operation is necessary, the connection sleeve provided in the existing connection portion is a compression tool. Therefore, it is difficult to cut off at this portion, so that the other portion where the connecting sleeve of the edge line is not provided is cut off, and then the cut off portion is compressed and connected again using the connecting sleeve. I have to.
For this reason, every time the edge line is disconnected and connected, it is necessary to cut the edge line or peel off the coating of the edge line, which requires many work tools and increases the number of work steps. The work efficiency was poor.

  Further, when the separation and connection of the edge line are repeated many times, there are many connection portions on the edge line, and if there is no room for dimensional separation, the edge line needs to be replaced. In addition, since there are many insulating covers attached to the edge line with many sleeve connections, this cover is easily affected by wind, causing metal fatigue due to the fluctuation of the edge line, resulting in inconveniences such as disconnection of the edge line. Is concerned.

  Furthermore, when there are many sleeve connection points, when it is necessary to support the edge line, it becomes difficult to separate the sleeve connection part from the binding wire for support in accordance with the construction standard, and it is bound to the sleeve connection point. When the wire is wound in contact with the wire, there is a concern that the bind wire will be charged and an accidental power outage will occur.

  The present invention has been made in view of such circumstances, and even when the cutting and connecting work of the edge line is required a plurality of times, the number of connection points does not increase, and the replacement of the edge line becomes unnecessary. An object of the present invention is to provide an edge line connection connector that is less susceptible to metal fatigue due to wind and an insulating cover used for the edge line connection connector.

  In order to achieve the above object, an edge line connector according to the present invention is provided with an edge line insertion port for inserting a core wire of an edge line of an aerial distribution line, and a pair of conductive wires having bolt holes formed in a peripheral wall portion. A cylindrical conductor, a connecting conductor that is connected to the opposite side of the edge insertion port of each of the pair of cylindrical bodies, and electrically connects the pair of cylindrical bodies, and a bolt of the cylindrical body Bolt heads projecting outwardly into the holes and screwed together, adjusting the amount of screwing to adjust the amount of protrusion to the inside of the cylindrical body, and the connecting conductor to the insulator And fixing means for fixing.

Therefore, when connecting the edge lines drawn from the overhead distribution lines on both sides of the electric wire, the covering material at the end of each edge line is peeled off to expose the core wires, and the core wires of the exposed edge lines are separated. Are inserted into the edge insertion holes of the corresponding cylindrical body, and then the bolts are screwed together so that the core wire is pressed and fixed between the inner wall portion of the cylindrical body and the tip end portion of the bolt. May be electrically connected. Then, the edge line connecting connector is fixed to the insulator by being fixed to the insulator later by a fixing means provided on the connecting conductor, or by being previously fixed to the insulator.
When it is desired to disconnect the edge line, the bolt is loosened and inserted into the cylindrical body while the fixing state by the fixing means to the insulator is released or the fixing state by the fixing means to the insulator is maintained as it is. If the core line of the edge line that has been removed is removed, the cutting of the edge line is completed.

  For this reason, it is not necessary to cut off a portion other than the edge line connector of the edge line, and even when the edge line is disconnected and connected a plurality of times, the edge line connecting portion can be made one place. Also, when connecting edge lines, the core line at the end of the edge line may be inserted into the cylindrical body and bolted, and when disconnecting, the core line at the end of the edge line may be removed by loosening the bolt. Therefore, it is not necessary to cut the edge line or peel off the covering material each time the edge line is disconnected and connected as in the prior art, and the edge line is easily disconnected and connected.

  Here, as a fixing means, it is good also as a means engaged with a lever by the bind wire attached rotatably to the connection conductor. According to such a configuration, it is possible to fix the edge line connecting connector to the insulator by rotating the bind line around the conductor and engaging the insulator, and to bind the bind line to the insulator. By releasing the engaged state, it is possible to release the fixed state of the edge line connector to the insulator.

  Moreover, as a fixing means, it is good also as a means fastened with the fastening volt | bolt which penetrates a connection conductor and an insulator. According to such a configuration, if the connecting conductor is previously fastened to the insulator with the fastening bolt, the fixing to the pin insulator is completed at the time when the core wire of the edge line is fixed to the cylindrical body with the bolt. When the core wire of the edge line is removed from the cylindrical body by loosening the bolt, it is possible to release the fixing to the pin insulator, so there is no need to attach the edge line connecting connector to the pin insulator. Even when the line is also disconnected, it is not necessary to remove the edge line connector from the pin insulator, and the work efficiency of the edge line can be improved.

  Further, the connecting conductor may be detachable from the cylindrical body with a bolt. As a result, by changing the shape of the connecting conductors to not only a linear one but also a bent one as appropriate, it becomes possible to cope with various routing of the edge line, and it becomes possible to improve versatility. .

Furthermore, in order to protect the state where the edge line connector is attached to the insulator and to cover the charging part, an insulating first cover component member covering a part of the edge line connector and the first cover member An insulative second cover constituent member that is pivotally connected to the cover constituent member and covers the remaining portion of the edge line connector, the at least one of the first and second cover constituent members It is preferable to provide an insulating cover that also covers a portion of the insulator surface fixed by the fixing means.
According to such a configuration, the edge line connecting connector and the retaining part of the insulator that retains the edge line connector are covered with the insulating cover, so that it is possible to avoid the exposure of the charged part and to prevent accidents due to contact with birds and beasts. Is possible.

  As described above, according to the edge line connector of the present invention, a pair of conductive cylinders having an edge line insertion port and having a bolt hole formed in the peripheral wall portion, and the pair of cylinder bodies A connecting conductor that is electrically connected, a bolt that can adjust the amount of protrusion into the cylindrical body by adjusting the amount of screwing into the bolt hole of the cylindrical body, and the connecting conductor to the insulator Therefore, it is not necessary to separate and connect the edge line other than the edge line connector, and the edge line connection point can be made one place.

  For this reason, even if it is necessary to disconnect and connect many times at the same edge line, it is possible to disconnect it simply by loosening the bolt and pulling the core wire of the wire from the cylindrical body. Since the connection of the edge line is completed by inserting it into the cylindrical body and tightening the bolt, the number of connection points of the edge line is not increased, and it is not necessary to replace the edge line. In addition, the bolts provided on the cylindrical body can be tightened or loosened by gripping and operating the bolt head protruding outside the cylindrical body with an indirect hot wire tool. Work is facilitated, work efficiency can be increased, and variations in work finishes of individual persons can be avoided.

Further, even when a cover is provided at the connection portion of the edge line, it is possible to reduce the influence of the shaking due to the wind, and it is possible to avoid disconnection due to metal fatigue of the edge line.
Furthermore, since the fixing means fixed to the insulator is provided, it is not necessary to prepare a fixing tool separately to form the fixed state to the insulator, and the formation of the fixed state to the insulator can be easily secured. Is possible.

  If the connecting conductor can be attached to and detached from the cylindrical body with bolts, it is possible to cope with various routings of the edge line by changing the connecting conductor having a different shape, thereby enhancing versatility. It becomes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The best embodiment of the present invention will be described below with reference to the accompanying drawings.
1 and 2, the edge line connector 1 includes a pair of cylindrical bodies 2, a connecting conductor 3 that electrically connects the pair of cylindrical bodies 2, and a fixing that is fixed to the pin insulator 4. Means.

The cylindrical body 2 is made of a conductive metal such as an aluminum alloy, copper, or iron, or a conductive resin. The cylindrical body 2 has edge lines 5 at the ends of the cylindrical bodies 2 that are away from each other. An edge line insertion port 2a for inserting the core wire 5b exposed by peeling off the covering material 5a at the end is formed, and a connection conductor insertion port 2b for inserting the connection conductor 3 is formed at the end on the side close to each other. For example, it has a cylindrical shape.
In addition, two bolt holes 6 that are spaced apart from each other by a predetermined distance along the axial direction are formed in the peripheral wall portions of the respective cylindrical bodies 2, and bolts 7 are bolt heads 7 a in the respective bolt holes 6. Are screwed together in a state of protruding outward from the cylindrical body 2.

  Each bolt 7 can adjust the amount of protrusion to the inside of the cylindrical body 2 by turning the bolt head 7a with an indirect hot wire tool or the like to adjust the amount of screwing into the bolt hole 6. The bolt 7 on the connection conductor insertion port side is used as a connection conductor fixing bolt 7α for fixing the connection conductor 3, and the bolt 7 on the edge line insertion port side is an edge for fixing the edge line 5. Used as a wire fixing bolt 7β.

  The connecting conductor 3 is a cylindrical one made of a conductive material made of a copper wire material such as aluminum alloy, copper, or iron, and has a diameter larger than the opening diameter of the connecting conductor insertion port 2b of the cylindrical body 2. A small diameter is formed. The connecting conductor 3 is inserted into the cylindrical body 2 through the respective connecting conductor insertion ports 2b, and the connecting conductor fixing bolt 7α is screwed to the inner wall portion of the cylindrical body 2 and the bolt (connecting conductor fixing). The connecting conductor 3 is pressed and fixed to the tip of the bolt 7α). In this example, the connecting conductor 3 is formed in a straight line, and a portion exposed between the paired cylindrical bodies is set to have a length substantially equal to or slightly shorter than the diameter of the pin insulator 4.

  In this example, the fixing means for fixing to the pin insulator 4 includes a bind wire 10 that is rotatably attached to the connecting conductor 3 and can be engaged with the constricted portion 4 a of the pin insulator 4. The pair of hinge portions 10a wound around the connecting conductor 3 so as to be rotatable, and the curvature connected to the pair of hinge portions 10a and slightly smaller than the diameter of the upper portion of the pin insulator 4 A radially arcuate portion 10b that is curved with a radius and an intermediate portion (for example, a portion farthest from the hinge portion 10a) of the arcuate portion 10b radially outward so as to allow elastic expansion and contraction of the arcuate portion 10b. And a protruding bent portion 10c that protrudes.

  The pair of hinge portions 10a are locked with a gap so as to be positioned in the vicinity of both ends in the axial direction of the exposed portion of the connection conductor 3 (on the end surface of the connection conductor insertion port 2b into which the connection conductor 3 is inserted). Since the arc-shaped portion 10b is formed to have a diameter somewhat smaller than the diameter of the pin insulator 4, the arc-shaped portion 10b is locked in a state of being brought into contact with or close to the end surface. Is pressed against the periphery of the top of the pin insulator 4, the protruding bent portion 10c expands to increase the diameter of the arcuate portion 10b, and when the arcuate portion 10b reaches the constricted portion 4a of the pin insulator 4, the protruding bent portion 10c narrows. The diameter of the arcuate portion 10b is restored to its original size (by restoration).

  When such an edge line connector 1 is fixed to the side of the pin insulator 4, the edge line connector 1 is covered with the upper portion of the pin insulator 4 so as to cover a portion that becomes a charging portion. For this reason, for example, an insulating insulating cover 12 as shown in FIG. 3 may be used.

  The insulating cover 12 is a first cover constituent member that covers the upper part of the pin insulator 4 and the pair of cylindrical bodies 2 and the upper half of the connecting conductor 3 of the edge line connector 1 fixed to the pin insulator 4. 12a and a second cover constituent member 12b that is rotatably connected to the first cover constituent member 12a and covers the lower half of the pair of cylindrical bodies 2 and the connecting conductor 3 of the edge line connector 1 It is configured. The first cover constituting member 12a includes an insulator covering portion 13a including an arc wall portion 13a-1 hanging from above so as to cover up to the bind line 10 engaged with the pin insulator 4, and the edge line connector 1 A connector covering portion 13b that covers substantially the upper half together with the bolt 7 is integrally formed, and the second cover constituting member 12b is connected to the side edge of the connector covering portion 13b of the first cover constituting member 12a via the hinge portion 14. It is integrally connected, and is formed in a circular arc shape so as to cover the lower side of the edge line connector 1, and a notch 15 is formed to avoid interference with the pin insulator 4.

  In addition, the connector covering portion 13b and the second cover constituting member 12b of the first cover constituting member 12a have a contact edge extending in a strip shape on the side edge opposite to the hinge portion 14 that connects them. Portions 16a and 16b are formed. An engagement hole 17 is formed on one of the contact edges 16a and 16b, and an engagement protrusion 18 that can be engaged with the engagement hole 17 is provided on the other. 18 is engaged with the engagement hole 17 so as not to be separated.

  In the above configuration, the connection work between the edge lines 5 will be described. First, the connecting conductor 3 is inserted into the connecting conductor insertion port 2b of the pair of cylindrical bodies 2, and the connecting conductor fixing bolt 7α is tightened. Thus, the connecting conductor 3 is fixed to the pair of cylindrical bodies 2, and the pair of hinge portions 10a of the bind wire 10 are rotatably attached to the connecting conductor 3, and the edge line shown in FIG. The connection connector 1 is formed.

  Then, for each of the edge lines 5 drawn from the unillustrated retention clamps before and after the utility pole, the covering material 5a at the end of the edge line 5 is peeled to expose the core wire 5b, and the core wire 5b is exposed to the edge of the cylindrical body 2 After inserting into the wire insertion port 2a, the edge line fixing bolt 7β is tightened, and the core wire 5b of the edge line 5 is pressed between the inner wall of the cylindrical body 2 and the tip portion of the edge line fixing bolt 7β. It fixes in a state and forms a state as shown in FIG.2 (c). After the edge line 5 is connected to both sides of the edge line connector 1 in this way, the edge line connector 1 is brought close to the pin insulator 4 from the side, and the connecting conductor 3 is connected to the constricted portion 4a of the pin insulator 4. In this state, the bind wire 10 is rotated and applied to the upper portion of the pin insulator 4, and the arc-shaped portion 10b of the bind wire 10 is pressed against the upper peripheral edge of the pin insulator 4 as it is. Is spread in the radial direction, and the head of the pin insulator 4 is passed between the arcuate portions 10b. When the head of the pin insulator 4 passes through the arc-shaped portion 10b, the diameter of the arc-shaped portion 10b is reduced by the restoring force of the protruding bent portion 10c, and as shown in FIG. 10b is engaged with the constricted portion 4a of the pin insulator 4. For this reason, the edge line connector 1 is fixed to the side part of the pin insulator 4 by one touch by rotating the bind line 10.

  After that, the first and second cover constituent members 12a and 12b of the insulating cover 12 are opened by rotating around the hinge portion 14, and the cylindrical body 2 and the connecting conductor 3 constituting the edge line connector 1 are opened. The first cover constituting member 12a is covered from above so as to cover the upper part of the pin insulator 4 and the bind wire 10 engaged with the pin insulator 4, and then the second cover constituting member 12b is centered on the hinge portion 14. And the engagement protrusion 18 formed on the contact edge portion 16b of the second cover component member 12b is covered with the cylindrical projection body 2 and the connecting conductor 3 of the edge line connector 1 from below. The first cover constituting member 12a is engaged with the engagement hole 17 formed in the contact edge portion 16a of the connector covering portion 13b. As a result, as shown in FIG. 4B, insulation is performed so as to cover the cylindrical body 2 and the connecting conductor 3 of the edge line connector 1 serving as a charging unit and the bind wire 10 engaged with the insulator 4. A cover 12 is attached.

On the other hand, when the edge line 5 is removed from the edge line connector 1, first, the second cover constituent member 12 b is rotated around the hinge portion 14 to engage with the first cover constituent member 12 a. The combined state is released, and then the first cover constituent member 12a is lifted upward and removed from the edge line connector 1 and the pin insulator 4.
Thereafter, the binding wire 10 engaged with the constricted portion 4a of the pin insulator 4 is rotated so as to extract the arcuate portion 10b from the head of the pin insulator 4 by pushing up the protruding bent portion 10c from below. The edge of the cylindrical body 2 of the edge line connection connector 1 after the connection state of the connection connector 1 to the pin insulator 4 is released or in a state where the connection state of the edge line connection connector 1 to the pin insulator 4 is maintained as it is. The wire fixing bolt 7β may be loosened to remove the core wire 5b of the edge line 5 from the cylindrical body 2.

  Therefore, in such a configuration, when connecting the edge lines 5 drawn from the retaining clamps that hold the overhead distribution wires on both sides of the utility pole, the core wires 5b of the respective edge lines 5 are connected to the cylindrical body 2. It is possible to connect the edge lines by inserting them into the edge line insertion port 2a and tightening the edge line fixing bolts 7β, and when it is desired to disconnect the edge lines 5, loosen the edge line fixing bolts 7β. If the core wire 5b of the edge line 5 inserted into the cylindrical body 2 is removed, the separation of the edge line 5 is completed, so that the edge line 5 is cut or covered each time the edge line 5 is disconnected and connected. The work of stripping off the material 5a is not necessary, and the edge line 5 can be easily disconnected and connected.

  In addition, since it is not necessary to separate the edge line 5 other than the edge line connector, it is possible to have only one edge line connection place, and the same edge line 5 needs to be disconnected and connected many times. Even in this case, the edge line fixing bolt 7β is loosened and the core wire 5b of the edge line 5 can be pulled out from the cylindrical body 2, and the core wire 5b of the edge line 5 can be separated into the cylindrical body 2. If the edge line fixing bolt 7β is inserted and tightened, the edge line 5 can be connected to the cylindrical body 2, so that the number of connection points of the edge line 5 does not increase, and the edge line 5 needs to be replaced. Disappear.

  Furthermore, since each bolt 7 provided in the cylindrical body 2 has a bolt head 7a protruding outside the cylindrical body 2, it can be tightened or loosened with an indirect hot-line tool, and the connection of the edge line is possible. As a result, the work can be easily separated and the work efficiency can be increased, and variations in the work of each person can be avoided.

Furthermore, since the connection portion of the edge line 5 is provided in a portion shifted from the pin insulator 4 and no insulating cover is provided there, it is possible to reduce the influence of the swaying by the wind. It is possible to avoid disconnection due to metal fatigue.
Further, since the bind wire 10 is rotatably attached to the connecting conductor 3, it can be attached to the pin insulator 4 with one touch, and the fixing means to the pin insulator 4 is independent from the edge line connector 1. Therefore, it is possible to easily secure the formation of the fixed state to the pin insulator 4.

  In the above configuration, the edge line connector 1 is fixed to the side of the pin insulator 4. However, the edge line connector 1 may be fixed to the upper portion of the pin insulator 4. Such an edge line connector 1 is shown in FIGS.

  This example is different from the above configuration example in that the bind line 10 attached to the edge line connector 1 is different. The bind wire 10 used in this example includes a pair of hinge portions 10a wound around the connecting conductor 3 so as to be rotatable, and is connected to the pair of hinge portions 10a and locked to the constricted portion 4a of the pin insulator 4. The arcuate portion 10b is formed in a possible size, and two such binding wires 10 are attached to the connecting conductor 3 so as to be rotatable in opposite directions, and pin insulators are provided. The edge line connector 1 is fixed to the pin insulator 4 by rotating the bind wire 10 with the edge line connector 1 placed on the top of the pin 4 and engaging with the constricted portion 4 a of the pin insulator 4. I have to.

For example, an insulating cover as shown in FIG. 7 is used as the insulating cover 12 that protects the state where the edge connector 1 is attached to the pin insulator 4. A first cover constituting member 12c that covers substantially the upper half and substantially one half of the edge line connector 1 fixed to the pin insulator 4, and is pivotally connected to the first cover constituting member 12c. The second cover constituting member 12d covers the remaining approximately half of the upper portion of the pin insulator 4 and the approximately half of the remaining one side of the edge line connector 1. The first cover constituting member 12c includes an insulator covering portion 13a having an arc wall portion 13a-1 hanging from above so as to cover up to the bind line 10 engaged with the pin insulator 4, and the edge line connector 1 A connector covering portion 13b that covers substantially half of one side together with the bolt 7 with respect to a vertical plane including the axis is integrally formed, and the second cover constituent member 12d is formed substantially symmetrically with the first cover constituent member 12c. , With respect to a vertical surface including an insulator covering portion 13c having an arc wall portion 13c-1 hanging from above so as to cover up to the bind line 10 engaged with the pin insulator 4, and an axis of the edge line connector 1 A connector covering portion 13d that covers substantially the other half of the one side together with the bolt is integrally formed. At the upper edge portions of the connector covering portions 13b and 13d of the respective cover constituent members 12c and 12d, the first cover Hinge portion 14 connecting the formed member 12c and the second cover component 12d rotatably are formed.
In this example, the connecting conductor 3 is formed in a straight line, but the exposed portion between the pair of cylindrical bodies is formed longer than the diameter of the pin insulator 4. Since other configurations are the same as those in the above configuration example, the same portions are denoted by the same reference numerals and description thereof is omitted.

  In such a configuration, the connecting conductor 3 is inserted into the connecting conductor insertion ports 2b of the pair of cylindrical bodies 2 and the connecting conductor fixing bolts 7α are tightened, thereby connecting the connecting conductor 3 to the pair of cylindrical bodies. An edge line connection connector 1 is formed which is fixed to the body 2 and has a pair of binding wires 10 rotatably attached to the connecting conductor 3, and is drawn from unillustrated retention clamps before and after the utility pole. The core wire 5b is inserted into the edge line insertion port 2a of the cylindrical body 2, the edge line fixing bolts 7β are tightened to connect the respective edge lines 5 with the edge line connection connector 1, and the edge line connection connector 1 is connected. The side of the connecting conductor 3 is brought into contact with the groove 4b (shown in FIG. 1) formed in the upper portion of the pin insulator 4 close to the pin insulator 4, and the bind wire 10 is rotated in this state. To the constricted part 4a of the pin insulator 4 Then, as shown in FIG. 8A, the bind wire 10 is locked to the head of the pin insulator 4. Thereby, it becomes possible to fix the edge line connector 1 to the upper part of the pin insulator 4 by one touch.

  After that, the first and second cover constituent members 12c and 12d of the insulating cover 12 shown in FIG. 7 are opened around the hinge portion 14, and the cylindrical body 2 and the connecting conductor 3 constituting the edge line connector 1; 8 and the pin insulator 4 so as to be covered from above, both cover constituent members 12c and 12d are closed, and the upper part of the edge line connector 1 and the pin insulator 4 is sandwiched together with the bind wire 10 as shown in FIG. As shown, the insulating cover 12 is attached so as to cover the entire charging portion (the cylindrical body and the connecting conductor of the edge line connector and the bind line engaged with the insulator).

When the edge line 5 is removed from the edge line connector 1, the first and second cover constituent members 12c and 12d are rotated about the hinge portion 14 to release the mutual engagement state. Later, the insulating cover 12 is lifted upward and removed from the edge line connector 1 and the pin insulator 4.
Then, after releasing the fixed state to the pin insulator 4 of the edge line connection connector 1 by pushing up the bind wire 10 engaged with the constricted portion 4a of the pin insulator 4 to release the engagement state with the pin insulator, Alternatively, the core wire of the edge line 5 is loosened by loosening the edge line fixing bolt 7β provided on the cylindrical body 2 of the edge line connector 1 while maintaining the state of fixing the edge line connector 1 to the pin insulator 4 as it is. 5b is removed from the cylindrical body 2.
Therefore, even in such a configuration, it is possible to obtain the same effect as in the configuration example.

  In the above configuration, the connecting conductor 3 is formed in a straight line and the edge line 5 is connected to the edge line connector 1 from a direction different from the pin insulator 4 by 180 degrees. Is close to the pin insulator 4 at a certain angle, the connecting conductor 3 is bent along the angle as shown in FIGS. 9 and 10 (in this example, approximately 90 degrees). The edge line connector 1 (bent) may be used. The bind wire 10 used in this example includes a pair of hinge portions 10a wound around both ends of the bent connecting conductor 3, and a pin insulator 4 connected to the pair of hinge portions 10a. The arc-shaped portion 10b curved with a curvature radius somewhat smaller than the diameter of the upper portion of the arc-shaped portion, and the elastic diameter of the arc-shaped portion at the intermediate portion (for example, the portion farthest from the hinge portion 10a) of the arc-shaped portion 10b. It has a protruding bent portion 10c protruding outward in the radial direction so as to allow expansion and contraction.

  The pair of hinge portions 10a are pivotally locked with a gap so as to be positioned in the vicinity of both ends of the exposed portion of the connecting conductor 3, and the arcuate portion 10b has a diameter larger than the diameter of the pin insulator 4. Since the arc-shaped portion 10b is pressed against the top peripheral edge of the pin insulator 4, the protruding bent portion 10c expands to increase the diameter, and the arc-shaped portion 10b becomes the constricted portion 4a of the pin insulator 4. When it reaches, the protruding bent portion 10c narrows (restores) so that the diameter returns to the original size.

As the insulating cover 12 for protecting the state where the edge line connector 1 is attached to the pin insulator 4, for example, a cover as shown in FIG. 11 is used. A first cover constituent member 12e that covers the pair of cylindrical bodies 2 and the upper half of the connecting conductor 3 of the edge line connector 1 fixed to the pin insulator 4, and a first cover constituent member 12e The second cover constituting member 12f is movably connected and includes a pair of cylindrical bodies 2 of the edge line connecting connector 1 and a lower half of the connecting conductor 3. The first cover constituting member 12e includes an insulator covering portion 13a including an arc wall portion 13a-1 that hangs down from above so as to cover up to the bind wire 10 engaged with the pin insulator 4, and the edge line connector 1 A connector covering portion 13b that covers the upper side together with the bolt 7 is integrally formed, and the second cover constituting member 12f is integrally provided with a hinge portion 14 on the side edge of the connector covering portion 13b of the first cover constituting member 12e. It is connected, and is formed in a circular arc shape so as to cover the lower side of the edge line connector 1, and a notch 15 is formed to avoid interference with the pin insulator 4.
In addition, since the other structure is the same as that of the said structural example, it attaches | subjects the same code | symbol to the same location, and abbreviate | omits description.

  In such a configuration, the connecting conductor 3 is inserted into the connecting conductor insertion port 2b of the pair of cylindrical bodies 2, and the connecting conductor fixing bolt 7α is tightened to connect the connecting conductor 3 to the pair of cylindrical bodies 2. In addition, an edge line connector 1 having a bind wire 10 rotatably attached to the connecting conductor 3 is prepared, and the core wire 5b of the edge line 5 drawn from a tension clamp (not shown) before and after the utility pole is provided. Inserted into the edge line insertion port 2 a of the cylindrical body 2, tightened the edge line fixing bolt 7 β, and connected each edge line 5 with the edge line connector 1, and connected the edge line connector 1 to the pin insulator 4. On the other hand, the bent side surface of the connecting conductor 3 is brought into contact with the constricted portion 4a of the pin insulator 4 at two locations, and the bind wire 10 is rotated in this state, thereby constricting the constricted portion 4a of the pin insulator 4. And is also shown in FIG. Thus, the bind wire 10 is engaged with the head of the pin insulator 4. Thereby, it becomes possible to fix the edge line connector 1 to the upper part of the pin insulator 4 by one touch.

  Thereafter, the first and second cover constituent members 12e and 12f of the insulating cover 12 are opened with the hinge portion 14 as the center, the cylindrical body 2 and the connecting conductor 3 constituting the edge line connector 1, and the pin insulator 4 The first cover constituting member 12e is covered from above so as to cover the upper portion of the wire and the bind wire 10 engaged with the pin insulator 4, and then the second cover constituting member 12f is rotated around the hinge portion 14 as a center. The cylindrical body 2 and the connecting conductor 3 of the edge line connector 1 are covered from below, and the engagement protrusion 18 formed on the abutting edge of the second cover constituent member 12f is used as the first cover constituent member 12e. The connector is engaged with an engagement hole 17 formed at the contact edge of the connector covering portion 13b. As a result, as shown in FIG. 12B, the tubular body 2 and the connecting conductor 3 of the edge line connector 1 serving as the charging unit and the bind wire 10 engaged with the pin insulator 4 are covered. An insulating cover 12 is attached.

When the edge line 5 is removed from the edge line connector 1, the first and second cover constituent members 12e and 12f are rotated around the hinge portion 14 to release the mutual engagement state. Later, the insulating cover 12 is lifted upward and removed from the edge line connector 1 and the pin insulator 4.
Thereafter, the bind wire 10 engaged with the constricted portion 4a of the pin lever 4 is pushed up to release the engagement state of the pin lever 4 with the head, and the fixed state of the edge line connecting connector 1 to the pin lever 4 is set. After the release, or in a state where the fixed state of the edge line connecting connector 1 to the pin insulator 4 is maintained as it is, the edge line fixing bolt 7β of the cylindrical body 2 of the edge line connecting connector 1 is loosened to loosen the edge line 5. What is necessary is just to remove the core wire 5b from the cylindrical body 2. FIG.
Therefore, even in such a configuration, it is possible to obtain the same effect as in the configuration example.

  In the above configuration, the example in which the edge line 5 is connected to the cylindrical body 2 of the edge line connector 1 and then the bind wire 10 is engaged and fixed to the pin insulator 4 is shown. 1 may be fixed to the pin insulator 4 in advance, and the edge line 5 may be fixed to the cylindrical body 2 in this state.

  The fixing means for fixing the edge line connector 1 to the pin insulator 4 in advance is not particularly limited, but even if the edge line connector is fixed to the pin insulator with a bind line in advance, FIG. As shown, the connecting conductor 3 and the pin insulator 4 may be fastened by a bolt 20 that penetrates the connecting conductor 3 and the pin insulator 4. In FIG. 13, a fitting groove 4 c for fitting the connecting conductor of the edge line connector 1 is formed on the upper surface of the pin insulator 4, and the pin insulator 4 is perpendicular to the fitting groove 4 c. A bolt insertion hole 4d is formed in the head, and a lateral hole 3a that can communicate with the bolt insertion hole 4d formed in the pin insulator 4 is formed in the intermediate portion of the connecting conductor 3 of the edge line connector 1. The bolt 20 is passed through the bolt insertion hole 4d and the lateral hole 3a, and the nut 21 is screwed into the bolt 20 so that the connecting conductor 3 of the edge line connector 1 is fastened to the pin insulator 4. Also good.

  In this example, the charging part may be covered similarly using an insulating cover as shown in FIG. That is, the first cover constituting member 12g that covers substantially the upper half of the pin insulator 4 and substantially one half of the edge line connector 1 fixed to the pin insulator 4, and the first cover constituting member 12g The second cover constituting member 12h is pivotally connected and covers the remaining substantially half of the upper part of the pin insulator 4 and the substantially half of the remaining one side of the edge line connector 1. The first cover constituting member 12g includes an insulator covering portion 13a including an arc wall portion 13a-1 that hangs down from above so as to cover up to the bolt 20 or the nut 21 inserted through the pin insulator 4, and the edge line connector 1 The connector cover 13b that covers substantially half of one side with respect to the vertical plane including the axis of the connector is integrally formed, the second cover component 12h is formed symmetrically with the first cover component 12g, and the pin insulator The insulator covering portion 13c having an arc wall portion 13c-1 that hangs down from above so as to cover up to the bolt 20 or the nut 21 that is inserted into the nut 4 and the vertical plane including the axis of the edge line connector 1 A connector covering portion 13d that covers approximately half of one side is integrally formed, and the first cover constituting member 1 is formed at the upper edge portion of the connector covering portions 13b and 13d of the respective cover constituting members 12g and 12h. Hinge portion 14 that pivotally connected to the a second cover component 12b is formed.

  Therefore, in such a configuration, the edge line connecting connector is fixed to the pin insulator 4 in advance, so that when the core wire 5b of the edge line 5 is fixed to the cylindrical body 2 with the bolt 20, the pin insulator of the edge line 5 is used. 4 is completed, and if the core wire 5b of the edge line 5 is removed from the cylindrical body 2 by loosening the bolt 20, the fixed state to the pin insulator 4 can be released at that time, It is no longer necessary to attach the edge line connector 1 to the pin insulator 4, and when the edge line 5 is cut off, it is not necessary to remove the edge line connector 1 from the pin insulator 4, and the edge line is disconnected and connected. Work can be performed efficiently.

  In the above configuration, the insulating cover 12 is not limited to the above-described one, and may cover the charging unit. However, from the viewpoint of workability, the two covers as described above. It is desirable to be constituted by constituent members.
