Description

  The present invention attaches or removes from the overhead power distribution line an electrical wire connector for holding the exposed core wire of the overhead wire distribution line and the exposed core wire of the branch line such as a draw line branched from the overhead power distribution line. It is related with the structure of the instrument used in order to do.

  In the case of branching a branch line such as an underline from an overhead distribution line such as a high-voltage line in an overhead line state, for example, a first wire connector of the type shown in FIG. 1 and the second electric wire connector of the type shown in FIG. 5 is used.

  Among these, the first electric wire connector has a pair of sandwiching bodies (fixed side gripping body, movable side gripping body) connected so that the inner surfaces facing each other approach and separate from each other, and the inner surfaces facing each sandwiching body are close to each other In this state, a pair of first concave grooves (for overhead wires) formed separately at the distal end portion and the proximal end portion of the inner surface of each clamping body so that the exposed core wires of the overhead distribution lines and branch lines can be supported in parallel. ) And the second concave groove (for the underline), each core wire of the aerial distribution line and branch line, and the first concave groove and the second concave groove of each sandwich body are electrically connected. Connection holding means for holding the proximity state. And the 1st connector for electric wires is what the plate-shaped holding part protruded from the lower part of the fixed side holding body.

  As a result, by gripping the gripping part with the insulating jacket and pushing up the first electric wire connector, the distal end side of the movable gripping body swings away from the fixed gripping body, and both gripping bodies are moved upward. It is possible to open and hold the aerial distribution line with the first concave groove of the fixed side gripping body and the first concave groove of the movable side gripping body.

  On the other hand, the second electric wire connector has a pair of first concave grooves for gripping the core wires of the overhead distribution wires and second concave grooves for gripping the core wires of the branch wires in a form that is continuous with the inner surface. For holding the proximity state of each clamping body so that the cores of the overhead distribution lines and branch lines and the first and second concave grooves of each clamping body are electrically connected to each other. Connection holding means. And in this 2nd connector for electric wires, both ends are connected with the lower part of both clamping bodies, and it is mainly the C-shaped spring which always urges both clamping bodies in the direction which adjoins. It is comprised and does not have the holding part hold | gripped with an insulating jacket like the 1st connector for underline electric wires.

  Along with this, the second electric wire connector is attached to and detached from the aerial distribution line by using, for example, the underline connector attaching tool shown in Patent Document 2 without using an insulating unit. ing.

  Outline of the underline connector mounting tool shown in Patent Document 2 is as follows: an L-shaped base provided at the tip of the hot stick, a fixing plate erected from one end extending in the lateral direction of the base, and a vertical direction of the base A cylinder part that is provided on the tip of the other end in a laid-down state and is threaded inside, a screw rod that is inserted through the cylinder part, and a movable plate that is attached to the fixed plate side end of the screw rod via a ball joint The movable plate is formed with a hole portion that can accommodate the entire pull-down connector, and a notch that is located below the hole portion and can accommodate a spring as a connection holding means. It has become.

  With the pull-down connector mounting tool having such a configuration, the screw connector is loosened and the movable plate is separated from the fixed plate, and then the bolt head of the pull-down connector is connected to the fixed one side. In this state, when the pull-down connector is inserted between the fixed plate and the movable plate and the screw rod is rotated so that the movable piece moves to the fixed piece side, the lower portion of the movable plate is provided at the base. The upper end of the movable plate presses the pull-down connector against the fixed plate, and the pull-down connector is held by the pull-down connector mounting tool. This is done by setting the state.

  However, in the case of an attachment / removal tool for a wire connector provided at the tip of a hot stick, such as the underline connector attachment tool shown in Patent Document 2, the underline connector attachment tool holds the pull-down connector. In this state, the pull-down connector is attached to an overhead distribution line such as a high-voltage line, so both the weight of the pull-down connector and the weight of the pull-down connector mounting tool are attached to the spring of the pull-down connector. Therefore, there is a possibility that the spring of the pull-down connector is broken or detached from the pull-down connector, and the pull-down connector mounting tool falls.

  For this reason, in the underline connector installation tool shown in Patent Document 2, after being attached to the pull-down connector in a state where the aerial distribution line is gripped by the underline connector attachment tool, a hot wire provided with the underline connector attachment tool is provided. There is a problem in that it is impossible to perform other indirect hot-line work by removing the hand from the stick.

  Therefore, an object of the present invention is to provide an electric wire connector mounting device that is reduced in weight and prevents the electric wire connector from falling even if the spring of the electric wire connector is damaged or detached.

An electric wire connector attaching device according to the present invention includes a pair of connector main bodies for holding an aerial distribution line and a branch line, and an end of the connector main body as a mechanism for holding the overhead line and the branch line by the connector main body. An attachment device used for an electric wire connector having an arcuate elastic member that urges side portions in a relatively close direction, and having a bottomed hole portion to which the pair of connector main bodies are attached, and comprising a mounting fixture main body slit groove is formed in which the elastic member from the opening end of the hole extending in the axial direction of the hole is attached to the bottom side within the bore, mounted in the slit groove A locking mechanism comprising a locking portion for locking and releasing the elastic member and a pedestal that moves in synchronization with the locking portion is accommodated, and the pedestal is opposite to the hole portion from the mounting instrument body. Protruding into It is connected to the operating unit, the operating unit together with the locking portion is operated by rotating by holding the indirect hot tool, and an annular portion which is fitted on the fitting body, the overhead distribution lines A drop prevention mechanism comprising a distribution line hooking portion having a contact surface that can be hooked on an upper surface and a connecting portion that connects the annular portion and the distribution line hooking portion; The distance between the surface and the surface having the hole portion of the attachment device main body is larger than the total length of the connector main body and the elastic member of the electric wire connector (Claim 1).

An aerial distribution line is, for example, an aerial high-voltage electric line, and a branch line is, for example, an underline, and the following aerial distribution lines and branch lines are the same. And when a branch line is a drawing line, the kind of connector for electric wires is a connector for drawing, and the following connectors for electric wires are the same. The arc-shaped elastic member is, for example, a C-shaped spring. An indirect hot wire tool is an insulating Yatco, for example.

As a result, the wire connector mounting tool has an indirect hot wire, such as an insulated hook, with an operation portion protruding downward from the connector body, like a wire connector having a gripped portion gripped by an insulated jacket at the lower part of the fixed gripping body. Since it can be gripped and operated by a tool, it is not necessary to provide it integrally with the tip of the hot stick or attach it via a joint. Accordingly, since the electric wire connector attaching device does not have a hot stick, the weight of the hot stick is reduced, and the electric wire connector to which the electric wire connector attaching device is attached can be reduced in weight. Therefore, in the state where the wire connector attached to the wire connector mounting tool sandwiches the aerial distribution wire, the arc-shaped elastic member of the wire connector is prevented from being damaged or detached from the connector body. The worker can perform other work by removing the indirect hot wire tool such as an insulating jacket from the operation part of the electric wire connector mounting tool.

In addition, even if the arc-shaped elastic member of the wire connector is damaged by a load or detached from the connector body, the contact surface of the distribution wire hooking portion of the fall prevention mechanism comes into contact with the aerial distribution wire and gets caught. Since the connector connector can be reliably prevented from falling off, remove the indirect hot wire tool such as an insulating jacket from the operation part of the connector connector for electric wires, and perform other work including preparatory work and indirect hot wire work. It becomes possible to do it more safely.

  As described above, according to the present invention, the operation part that protrudes downward from the connector main body is provided in the same manner as the electric wire connector having the holding part to be held by the insulating unit in the lower part of the fixed side holding body. Can be gripped with an indirect hot wire tool such as an insulating Yatco, so there is no need to provide it integrally with the tip of the hot stick or attach it via a joint. As a result, since the wire connector mounting device does not have a hot stick, the weight of the hot stick is reduced, so the total weight of the wire connector to which the wire connector mounting device is mounted can be reduced. It becomes. Therefore, it is possible to prevent the arc-shaped elastic member of the electric wire connector from being damaged or detached from the connector main body in a state where the electric wire connector attached to the electric wire connector attaching device holds the overhead distribution line. , Because it is possible for an operator to remove the indirect hot wire tool such as an insulating jacket from the operation part of the electric wire connector mounting tool, so that the indirect hot wire work can be made more efficient and shorter. Can do.

Further, according to the present invention, even if the arc-shaped elastic member of the electric wire connector may be damaged by the load or detached from the connector main body, the contact surface of the electric wire hooking portion of the fall prevention mechanism is the aerial distribution electric wire. Since the wire connector mounting tool can be reliably prevented from falling, it is necessary to remove the indirect live tool such as an insulating jacket from the operation part of the wire connector mounting tool. It is possible to carry out other work including hot line work with more peace of mind. Therefore, since there is no anxiety during the work, it is possible to further improve the efficiency and time of the indirect hot line work.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The wire connector attaching device (hereinafter abbreviated as “attaching device”) 1 according to the present invention, for example, as shown in FIG. 5, holds both the aerial distribution line 200 and the branch line 300 to hold the aerial distribution line 200. Or attached to the wire connector 100 in a state before being suspended from the aerial distribution line 200 with only the branch line 300 interposed therebetween.

  First, the overhead distribution line 200 and the branch line 300 will be outlined. The overhead distribution line 200 is, for example, a high-voltage line that forms the main line of the electric wire. As illustrated in FIGS. 5 and 6, the overhead distribution line 200 includes a conductive core wire 201 and a coating 202 made of an insulating material that covers the periphery of the core wire 201. It is configured. The branch line 300 is, for example, a high-voltage underline, and is composed of a core wire 301 having electrical conductivity shown in FIG. 5 and a coating made of an insulating material that covers the periphery of the core wire 301 (not shown), like the overhead distribution line 200. ing.

  The wire connector 100 is also referred to as a pull-down connector or the like when the branch line 300 is a pull-down line, and is used when the branch line 300 such as a pull-down line is branched from the aerial distribution line 200.

  The electric wire connector 100 itself is a known one. However, when its configuration is outlined based on FIG. 5, the connector main body 101 and the connector main body 102 are basically configured. The connector main body 101 has a concave groove portion 101a for gripping the core wire 201 of the overhead power distribution line 200 and a concave groove portion 101b for gripping the core wire 301 of the branch line 300 in a form continuous to the inner surface. The connector main body 102 has a concave groove portion 102a for gripping the core wire 201 of the overhead power distribution line 200 and a concave groove portion 102b for gripping the core wire 301 of the branch line 300 in a form continuous to the inner surface. The connector main body 101 and the connector main body 102 are connected and integrated by a bolt 103 and a nut 104. However, the concave groove portion 101a and the concave groove portion 102a, and the concave groove portion 101b and the concave groove portion 102b may be close to each other. It is connected so that it can swing.

  The lower end portion of the connector main bodies 101, 102 opposite to the side having the concave groove portions 101a, 101b, 102a, 102b is located close to the concave groove portion 101a and the concave groove portion 102a, and the concave groove portion 101b and the concave groove portion 102b. In order to urge the connector main bodies 101 and 102 in the direction to be connected, each end portion of the elastic member 105 having an arcuate linear body is attached. The elastic member 105 is a spring curved in a C shape, for example.

  By configuring the electric wire connector 100 as described above, a force that resists the urging force of the elastic member 105 is applied, and the side of the connector main body 101, 102 that has the groove portions 101a, 101b, 102a, 102b is opened. The aerial distribution line 200 is disposed between the concave groove portion 101a and the concave groove portion 102a, or the branch line 300 is disposed between the concave groove portion 101b and the concave groove portion 102b, and then resists the biasing force of the elastic member 105. By releasing the force, the aerial distribution line 200 is held between the recessed groove portion 101a and the recessed groove portion 102a by the urging force of the elastic member 105, or the branch line 300 is held between the recessed groove portion 101b and the recessed groove portion 102b. Can do.

  As shown in FIGS. 1 to 7, the attachment device 1 includes an attachment device body 2, a locking mechanism 3, an operation unit 4, and a fall prevention mechanism 5.

  The fixture body 2 is substantially cylindrical and has a hole 21 with a bottom. The hole portion 21 is opened in a circular shape on the electric wire connector 100 side. In this embodiment, as shown in FIG. 7A, an opening end side space portion 21a having a relatively large inner diameter dimension, A central space 21b having a smaller inner diameter than the open end space 21a and a locking mechanism 3 described below are accommodated, and a locking mechanism accommodating portion 21c having a larger inner diameter than the central space 21b. Are connected along the axial direction of the fixture body 2. As shown in FIG. 7A, a through hole 21d through which the operation portion 4 protrudes to the outside is formed on the bottom surface of the fixture body 2 on the side of the locking mechanism accommodating portion 21c.

  The mounting fixture body 2 is opposed to two slit groove portions 22 extending from the opening end of the hole portion 21 along the axial direction of the hole portion 21 so that the elastic member 105 of the wire connector 100 can be mounted. It is formed in the form. For example, when a reference line extending horizontally through the center of the elastic member 105 is taken on the bottom surface of the slit groove portion 22, an outer peripheral surface of a portion below the reference line is in contact with the bottom surface of the slit groove portion 22. The arc shape may be formed along the outer peripheral surface of the elastic member 105 so as to widely contact the outer peripheral surface of the elastic member 105.

  In addition, the fixture body 2 is formed in such a manner that two notch grooves 23 face each other at a position shifted from the opening end of the hole 21 by an angle of 92 degrees with respect to the slit groove 22. The dimension L1 (shown in FIG. 1 (a)) taken in a straight line between the ends of the notch groove portion 23 is shown in FIG. 5 (b), as shown in FIG. 5 (b). It is slightly larger than the dimension in the short side direction.

  Furthermore, as shown in FIG. 3 in particular, an annular groove portion 24 extending in an annular shape is formed on the outer peripheral surface of the fixture body 2, and the annular groove portion 24 of the fall prevention mechanism 5 is attached to the annular groove portion 24. Therefore, in this embodiment, as shown in FIG. 3B, the annular portion 51 of the fall prevention mechanism 5 is engaged with the annular portion 51 so that the annular portion 51 of the fall prevention mechanism 5 is not easily detached. A plurality of triangular teeth that can be formed are formed side by side on the upper and lower edges of the annular groove 24.

  In addition, below the annular groove part 24 of the outer peripheral surface of the fixture body 2, the locking direction of the arrow to the elastic member 105 of the wire connector 100 by the locking mechanism 3 can be confirmed visually. The figure 25 may be provided by being pasted with a seal or drawn directly.

  As shown in FIG. 7, the locking mechanism 3 includes a disk-shaped pedestal 31 placed on the bottom surface of the locking mechanism accommodating portion 21 c of the hole 21, and a locking mechanism from the upper surface of the pedestal 31. It is comprised by the pillar part 32 which protruded in the accommodating part 21c, and the latching | locking part 33 extended in the radial direction of this pillar part 32 from the pillar part 32. As shown in FIG.

  As shown in FIGS. 7 (b) and 7 (c), the locking portion 33 has a crescent shape when viewed from the upper side in the axial direction of the hole 21, and is shown in FIG. 7 (a). As seen from the radial direction (lateral side) of the hole portion 21, the distance from the column portion 32 decreases for a while. Further, the locking portion 33 is connected to a portion on the upper end side of the column portion 32. Then, as shown in FIG. 7B, the pillar portion 32 and the locking portion 33 are prevented from coming into contact with the elastic member 105 when the elastic member 105 of the electric wire connector 100 is attached to the slit groove portion 22. Therefore, the engaging mechanism accommodating portion 21c has a size that can be accommodated in a substantially semicircular space on one side with the elastic member 105 as a boundary.

  As shown in FIG. 7A, the operation unit 4 includes a projecting portion 41 projecting from the lower surface of the base 31 to the outside (lower side) of the mounting fixture body 2 through the through hole 21 d, and the projecting portion 41. It is comprised with the holding part 42 provided in the front-end | tip of the direction. The gripping part 42 has a thickness and a width that can be gripped by a gripping part of a gripping part of an insulating jacket (not shown). The projecting portion 41 is integrally formed with both the base 31 and the gripping portion 42, and when the gripping portion 42 is rotated, the base 31, and thus the entire locking mechanism 3, is basically disposed through the projecting portion 41. It is possible to rotate in both directions in synchronization with the rotation of the grip portion 42. However, after the elastic member 105 of the electric wire connector 100 is attached to the slit groove portion 22, the grip portion 42 is rotated counterclockwise as shown in FIG. 7C from the state shown in FIG. 7B, for example. For example, even if it is attempted to rotate clockwise from the state shown in FIG. 7B, the grip portion 42 can be rotated clockwise because the pillar portion 32 hits the elastic member 105. Disappear.

  As shown particularly in FIG. 4, the fall prevention mechanism 5 includes an annular annular portion 51, a distribution line hooking portion 52 having a contact surface that can be hooked on the upper surface of the overhead distribution line 200, an annular portion 51, It is a linear body composed of a connecting portion 53 that connects the distribution line hooking portion 52, and is attachable to and detachable from the mounting fixture body 2. Thereby, when the fall prevention mechanism 5 deteriorates or breaks, only the fall prevention mechanism 5 can be replaced.

  The annular portion 51 is externally mounted on the annular groove portion 24 of the attachment instrument body 2, and the inner diameter dimension of the annular portion 51 is smaller than the portion other than the annular groove portion 24 of the attachment instrument body 2, and the annular groove portion of the attachment instrument body 2. 24 is slightly larger than the inner diameter of the innermost part. In addition, the depth of the annular groove portion 24 of the attachment device body 2 in the radial direction of the attachment device body 2 is such that, for example, 1/3 to 1/2 of the annular portion 51 is buried in the annular groove portion 24.

  As shown in FIG. 4C, the distribution line hooking portion 52 intersects the reference line B1 at an angle of 90 degrees in this embodiment when the reference line B1 on which the overhead distribution line 200 is installed is taken. As shown in FIG. 4A, the tip of the tip extends downward to form a claw portion 52a. As shown in FIG. 6, the dimensions of the wiring hook 52 from the fixture body 2 are such that when the fixture body 2 and the fall prevention mechanism 5 are viewed from above, the distribution line hook 52 is the overhead distribution line 200. It is set so as to intersect with the coating 202.

  A dimension L1 (shown in FIG. 5 (b)) from the upper surface of the annular portion 51 to the lower surface of the distribution line hooking portion 52 is as shown in FIG. 5 (a). Even if the mounting tool 1 is disposed below the elastic member 105 with respect to the wire connector 100 that is suspended from the distribution line 200, the dimension value does not hit the wire connector 100.

  The connecting portion 53 may be of any shape as long as it does not hinder the attachment of the attachment device 1 to the overhead distribution line 200. In this embodiment, as shown in FIG. 51, with the portion slightly displaced in the radial direction of the overhead distribution line 200 with respect to the reference line B1 as a base end, and diagonally in a direction away from the reference line B1 (however, as shown in FIG. 4B) After maintaining the same height), and then extending in a straight line (but maintaining the same height as shown in FIG. 4A) so as to be parallel to the reference line B1, As shown in FIG. 4B, it extends linearly upward.

  With reference to FIGS. 1, 5 and 7, a process of attaching the mounting tool 1 having such a configuration to the electric wire connector 100 in a state of being suspended from the overhead distribution line 200 with the overhead distribution line 200 interposed therebetween. explain.

  First, as shown in FIG. 1C and FIG. 7B, the locking portion 33 of the locking mechanism 3 does not intersect the straight line connecting the slit groove portions 22 and 22 of the locking mechanism accommodating portion 21c. Move to put. And the holding part 42 of the operation part 4 is hold | gripped with the holding part of an insulated jacket, and the fixture 1 is lifted to the connector 100 for electric wires. At this time, after lifting the attachment device 1 until the lower end of the claw portion 52a of the fall prevention mechanism 5 becomes higher than the overhead distribution line 200, the attachment device 1 is moved horizontally so that the wire connector 100 is connected to the claw portion 52a. When positioned between the part 53 and the part erected, the mounting tool 1 is slightly lowered to bring the mounting tool 1 into the position shown in FIG.

  Next, after aligning the position of the slit groove portion 22 of the fixture 1 and the elastic member 105 of the wire connector 100, the fixture 1 is lifted again. As a result, as shown in FIG. 5B, the elastic member 105 of the wire connector 100 is attached to the slit groove portion 22 of the fixture 1.

  Further, by rotating the gripping portion 42 of the operation unit 4 counterclockwise by the gripping portion of the insulating jacket, the base 31 and thus the locking portion 33 of the locking mechanism 3 are also rotated counterclockwise. 7C is inserted into the elastic member 105 of the electric wire connector 100 as shown in FIG. 7C, the elastic member 105 of the electric wire connector 100 is locked to the attachment device 1. Is done. At this time, even if the grip portion 42 of the operation portion 4 is rotated clockwise by the grip portion of the insulating jacket, the column portion 32 of the locking mechanism 3 cannot be rotated by hitting the elastic member 105 of the wire connector 100. The operator can immediately notice an error in the direction of rotation.

  Then, after the mounting of the attachment device 1 to the wire connector 100 is completed, the gripping portion of the insulating jacket can be removed from the gripping portion 42 of the operation portion 4, so that the load applied to the elastic member 105 of the wire connector 100 Since it is possible to limit the weight of the fixture 1 only, the possibility that the elastic member 105 of the wire connector 100 is damaged or pulled out is very small, and the worker can prepare for the next process with peace of mind. Can do the work for. In addition, since the locking direction by the locking mechanism 3 is indicated by an arrow in the mounting tool main body 2 of the mounting tool 1, the worker can move to the elastic member 105 of the electric wire connector 100 by the locking mechanism 3. It is also possible to prevent an artificial erroneous operation in which the grip portion 42 of the operation portion 4 is erroneously turned in the direction of releasing the lock.

  Moreover, since the attachment device 1 further includes the fall prevention mechanism 5, even if there is a problem that the elastic member 105 of the wire connector 100 is damaged or pulled out, in that case, the attachment device 1. Even if it falls, the distribution line hooking part 52 of the fall prevention mechanism 5 is immediately hooked on the upper surface of the covering 202 of the overhead distribution line 200 and is not detached from the overhead distribution line 200 by the claw part 52a. 1 can be prevented from falling to the ground or the like. Therefore, the worker can perform the work for preparation for the next process with greater peace of mind.
