Description

  The present invention relates to a power storage connector holding tool that is used to hold the power storage connector when two power cables are electrically connected using the power storage connector as a connection tool.

  In a high-voltage overhead distribution line, the power is stepped down and distributed to important power houses. A high-voltage cutout is provided between the overhead distribution line and the pole transformer, and these devices are connected by a high-voltage underline. Various connecting devices are used depending on the material of the conductor included in the high-voltage electric wire (see, for example, Patent Document 1). In areas around the coast where the salt damage is significant, electric wires with copper or copper alloy conductors are usually used for overhead distribution lines and high voltage underlines, so at high voltage underline branch connections from overhead distribution lines By connecting these electric wires using a connection tool having the same material made of copper or copper alloy, electrical corrosion or the like is prevented.

  FIG. 8 is a perspective view showing an example of a power storage connector that is commonly used as a connector for connecting electric wires having conductors such as copper. As shown in this figure, the power storage connector 30 is composed of a power storage connector main body 40 and a nut 48 provided with a power storage washer 50. 9 is a front view (FIG. 8A) and a side view (FIG. 10B) of the energy storage connector main body shown in FIG. 8, and FIG. 10 shows the energy washer 50 shown in FIG. It is a figure which shows the nut 48 provided, (a) is a front view, (b) is a side view (including a partial cross-sectional view), (c) is a plan view, and (d) is a bottom view. Furthermore, FIG. 11 has shown the connection state of two electric wires using this power storage connector, (a) is the figure seen from the direction along the axial direction of an electric wire, (b) is the axial direction of an electric wire. It is the figure seen from the direction at right angles to.

  The accumulator connector body 40 has a substantially U-shaped structure in which one ends of leg members 42 and 43 arranged in parallel with a predetermined distance apart are connected via a connecting member 44. Each of the leg members 42, 43 has end portions 42 a, 43 a having flat inner and outer surfaces parallel to each other on the side connected to the connecting member 44, and a cross section perpendicular to these length directions on the other end side is an arc And a thread portion 42b, 43b having a thread engraved on the circular arc surface, and a nut 48 is screwed into the thread portion 42b, 43b. ing. The inner peripheral surface of the connecting member 44 is formed in a substantially semicircular curved surface so as to be in close contact with the outer peripheral surface of the conductor having a circular cross section in the high-voltage electric wire. In the present specification, hereinafter, the “head” of the accumulator connector main body 40 is a group of the portions 42 a and 43 a having the inner and outer surfaces parallel to each other excluding the screw portions 42 b and 43 b of the leg members 42 and 43 and the connecting member 44. This will be referred to as (reference numeral 41).

  Further, as shown in FIGS. 8 and 10, the accumulator washer 50 includes a penetrating member 51 and an upper member 52. The penetrating member 51 has an intermediate portion whose cross section perpendicular to the opening direction of the nut 48 has a substantially rectangular shape and has a diagonal length slightly smaller than the opening diameter of the nut 48, and the intermediate portion opens the opening of the nut 48. It penetrates. Two claws 51a, 51a each having a width substantially equal to the length of the short side of the intermediate portion from both ends in the length direction of the intermediate portion (the opening direction of the nut 48); 51b and 51b are projected in a direction away from each other. The diameter of the circumscribed circle passing through the outermost ends of these claws 51 a, 51 a and 51 b, 51 b is set to be larger than the diameter of the opening end of the nut 48, so that the penetrating member 51 can be opened from any opening of the nut 48. The nut 48 is freely rotated within the opening of the nut 48 without falling off. As shown in FIG. 10 (c), projecting pieces 51c are erected perpendicularly to the outermost ends of the claws 51b and 51b, respectively, and open substantially upward toward the figure. It is formed in a shape. In addition, a through hole is formed at substantially the center of the penetrating member 51, and a shaft rod (screw) 54 is inserted through the through hole. The upper side of the through-hole is formed in an opening having a slightly larger diameter than the concentric circle, and the lower portion of the spring 57 is accommodated in the opening.

  As shown in FIGS. 8 and 10, the upper member 52 disposed above the penetrating member 51 has an upper surface formed in a V-shaped groove shape along the protruding direction of the claw 51 b of the penetrating member 51. A screw hole penetrating vertically is formed at a position corresponding to the through hole of the penetrating member 52 at a substantially center of the upper member 52, and a screw 54 is screwed through the screw hole. A slightly large-diameter opening is formed substantially concentrically near the penetrating member 51 of the screw hole, and the upper portion of the spring 57 is accommodated in the opening. The upper member 52 having such a structure is supported by the penetrating member 51 via a screw 54 while being biased upward by a spring 57, and both ends of the V-shaped groove in the engraving direction are claws 51b and 51b. Are sandwiched between projecting pieces 51c and 51c, respectively, so that they do not rotate around the axis of the shaft rod 54.

  When a high-voltage underline is newly installed in the overhead distribution line, the distribution line is in a power failure state. Therefore, when using this power storage connector 30, a high voltage is applied along the conductor portion 60 exposed in the middle of the overhead distribution line W1. An operator directly holds a position slightly separated from the conductors 60 and 61 of these two electric wires W1 and W2 so that the end conductors of the drawn line W2 are substantially parallel. In this state, the accumulator connector body 40 is used to cover the conductors 60 and 61 of the two high-voltage wires W1 and W2 in the space 45 of the accumulator connector body 40, and then the accumulator washer 50 is placed in the space 45. The nut 48 is screwed into the screw parts 42b and 43b while passing through. Thereby, the conductors (60, 61) of these two high-voltage electric wires W1, W2 can be sandwiched between the connecting member 44 and the upper member 52 of the energy storage washer 50 with the urging force of the spring 57 applied thereto, As a result, the two electric wires can be reliably fixed by the power storage connector 30. Thereafter, the accumulator connector and the conductors of the two high-voltage electric wires are covered with a protective cover (not shown).

  On the other hand, in the event of an accident such as breakage of the high voltage cutout or burning of the pole transformer, in order to replace the damaged or burned equipment, the accumulator connector is removed by indirect hot line work and the high voltage underline is charged. It is necessary to disconnect from the overhead distribution line of the power line to make it uncharged, and to prevent electric shocks and ground faults. Work to connect to overhead distribution lines is required.

  However, especially when connecting a high-voltage underline to the distribution line by indirect hot-wire work, the accumulator connector body is very small compared to the size of the opposing surfaces of a pair of gripping piece tips of a gripping tool. Therefore, depending on the Yatco, it is very difficult to pick the power storage connector body directly. Even if it is picked up, the operator must operate the Yatco operation lever continuously in order to maintain the power storage connector body. It was necessary for the workers to be skilled and skilled. In order to attach the accumulator connector to the conductor part of the distribution line and the high-voltage underline previously arranged in parallel, it is necessary to move the Yatco tip while the accumulator connector body is picked. When it is necessary to change the orientation of the connector body, the tip of the Yatsuko must be returned to the operator's hand, and there is a risk of dropping the accumulator connector body when moving the Yatco in this way. . For this reason, in order to make the high voltage underline uncharged, the storage connector for connecting the existing high voltage underline and the distribution line is removed, and the high voltage underline is removed from the exposed conductor portion of the distribution line. Even if it can be separated, it takes a long time to connect the high-voltage underline again to the exposed conductor using a power storage connector, and there is a problem that the work cannot be performed efficiently.

  For this reason, the high-voltage underline on the facility side that is to be replaced by cutting the middle of the high-voltage underline is not charged, instead of removing or attaching the accumulator connector that connects the high-voltage underline and the overhead distribution line. The high-voltage underline that was cut after the equipment was replaced was connected to the original state. As this connection work, the conductors are exposed by peeling off the coatings on the ends generated by cutting the high-voltage underline, and the exposed conductors are inserted into both ends of the tube sleeve and attached to the tip of the common operation rod. In general, a predetermined position on the outer peripheral surface of the tube sleeve is compressed by a compression pliers.

However, edge lines such as high-pressure underline sway under strong winds, making this connection difficult, and the compression pliers are very heavy. Since it becomes very heavy, there is a problem that the work becomes more difficult and the fatigue level of the operator increases. In addition, it is necessary to attach a cover to the connection part including the tube sleeve in the middle of the high-pressure underline. However, especially under strong wind conditions, this cover is subject to wind pressure, and the high-pressure underline is more likely to oscillate. The risk of disconnection at the connection points at the upper and lower ends of the underline was also a problem.
JP 2002-56942 A

  The present invention has been completed in view of the above circumstances, and the object of the present invention is to provide a high voltage underline on the exposed conductor portion of the overhead wire using a power storage connector while the overhead wire path is in a live state. An object of the present invention is to provide a power storage connector holding tool capable of connecting end conductors efficiently and safely.

According to the present invention, the above object is achieved by the following power storage connector clamps (1) to (3).
(1) First and second clamping means that are arranged opposite to each other and are urged in a direction in which the distal end sides approach each other and can clamp the main connector of the accumulator connector, and the distal ends of the respective clamping means are connected to each other. First and second picking means that open in a separating direction, and the first picking means includes at least a shaft of a support shaft that is fitted into a shaft support provided on the tip side of the first clamping means. Rotation around the center is possible, and is provided with a rotation restricting means for restricting its rotation at a position substantially perpendicular to the clamping surface of the head of the accumulator connector main body. Connector clamp.
(2) The rotation restricting means includes a rotation restricting surface extending outward substantially perpendicularly to the longitudinal direction at the tip of the first picking means, and the rotation restricting surface by the turning of the picking means. Is in contact with the sandwiched surface, thereby restricting the rotation of the first knob means and maintaining the position thereof substantially perpendicular to the sandwiched surface. Connector clamp.
(3) The power storage connector holding tool according to (1) or (2), wherein the second holding means also has the second knob means.

  Since the force accumulation connector holding tool of the present invention includes first and second holding means that are urged in the direction in which the distal end sides approach each other and can hold the force accumulation connector main body head, The part can be securely held by the urging force. In addition, since the energy storage connector holding tool of the present invention includes at least first knob means that is rotatably connected to the first holding means, the first knob means is attached during the operation of attaching the energy storage connector. Thus, the force accumulation connector can be held at a position away from the tip of the gripping tool, and the operator can efficiently connect the two high-voltage wires while confirming the direction of the force accumulation connector. Further, since it is not necessary to directly grip the power storage connector, there is no risk of dropping the power storage connector body when operating the indirect hot wire gripping tool, and no safety problem arises.

  Further, in the power storage connector holding tool of the present invention, the first picking means is pivotally supported by the first holding means so that the rotation of the first picking means is at a predetermined angle with respect to the holding surface of the power storage connector body. Rotation restricting means is provided to regulate the position of the wire, and using the lever principle, the two wires are twisted from the direction perpendicular to the axial direction so that the nut to the accumulator connector body can be easily screwed together. The direction of the power storage connector main body can be changed, and as a result, the operation of connecting two step-down electric wires using the power storage connector can be performed more efficiently by the indirect hot wire operation. In addition, since the work of cutting the middle of the high-voltage underline and replacing the high-voltage underline is not required, a problem such as disconnection of the high-pressure underline due to strong wind does not occur.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to the following embodiments. In this specification, the front end (side) of the clamping means refers to the side that opens to clamp the accumulator connector body head, and the rear end (side) refers to the longitudinal direction of the clamping means. It shall mean the opposite side (end) of the tip (side). In the following, when referring to both the first clamping means 10 and the second clamping means 11 and when referring to both the first knob means 15 and the second knob means 16, respectively, “first and second clamping means”. Means 10 and 11 ”and“ first and second picking means 15 and 16 ”will be simplified.

[Embodiment 1]
FIG. 1: has shown an example of embodiment of the power storage connector clamping tool of this invention, (a) is a front view, (b) is a right view, (c) is a left view. The power storage connector holding tool 1 of the present embodiment is arranged to face each other and make a pair with each other, a first holding means 10 and a second holding means 11, a connecting means 14 for connecting these rear ends, and a first A picking means 15 and a second picking means 16 are provided. The coupling body composed of the first clamping means 10, the second clamping means 11 and the coupling means 14 constitutes a plate spring that urges the distal ends of the first clamping means 10 and the second clamping means 11 toward each other. The first clamping means 10 and the second clamping means 11 can securely clamp the head portion 41 of the force accumulation connector main body 40 at the distal end side by the urging force of the plate spring. In the following, the leg members 42a and 43a facing the head 41 of the force-accumulation connector main body 40 that are clamped on the tip side of the first clamping means 10 and the second clamping means 11 of the energy-accumulating connector clamping tool 1 of the present invention. The outer surface will be referred to as a “held surface”.

  The lengths of the first and second clamping means 10 and 11 in the front-rear direction and the distance at the rear end side thereof (the length of the connecting means 14) are the same as the leading end sides of the first and second clamping means 10 and 11. When the heads 41 of the power storage connector main body 40 can be clamped when they are opened in directions away from each other, they can be set as appropriate. Moreover, although the magnitude | size can also be set suitably also about the width | variety of the 1st and 2nd clamping means 10 and 11, when these heads 41 are clamped, so that these width | variety is made narrower. The contact area between the sandwiched surfaces 42a and 43a and the first sandwiching means 10 and 11 is reduced, and the force accumulation connector body 40 is displaced or shifted in the state of being sandwiched by the first and second sandwiching means 10 and 11. There is a risk of rotation. Therefore, it is preferable that the width of each of the first and second clamping means 10 and 11 is from about ½ to about the same as that of the sandwiched surfaces 42a and 43a so as to eliminate this risk.

  As shown in FIG. 1 (b), the leading edge of the first clamping means 10 is provided with a notch 10a toward the rear end substantially in the middle in the width direction, and at both end edges of the notch 10a, The shaft support portions 12 are arranged at substantially right angles in the front-rear direction of the first clamping means 10 so as to sandwich them. These shaft support portions 12 and 12 have two tip portions on both sides excluding the notch 10a of the first clamping means 10 curved outwardly, and support shafts 17 and 17 provided at the tip of the first picking means 15 described later. Are formed, and the axis of each opening is arranged on the same straight line. The width of the notch 10a and the length of the shaft support portions 12 and 12 can be set as appropriate within the width of the first clamping means 10, but are not particularly limited. In the present embodiment, each of the widths of the first clamping means 10 is approximately 3 About 1 / minute. The shaft support portions 12 and 12 are formed by curving the tip edge of the first clamping means outwardly as in this embodiment, and the shaft support portion formed separately is the tip of the outer surface of the first clamping means 10. You may make it adhere to methods by methods, such as welding, adhesion | attachment, and screwing. In this case, the material of the shaft support parts 12 and 12 is not particularly limited as long as it can be fixed to the outer surface of the holding means by the above method, but it is preferable to select the same material as that of the first holding means 10 and 11.

  Further, as shown in FIG. 1C, shaft support portions 13, 13 having the same diameter opening and length also correspond to the shaft support portions 12, 12 at the tip edge of the second clamping means 11. Similarly arranged in position. Similar to the shaft support portions 12 and 12, the shaft support portions 13 and 13 are fitted with support shafts 18 and 18 provided at the tips of the second knob means 16 described later. These shaft support portions 13 and 13 may also be formed separately, and may be fixed to the front end portion of the outer surface of the second clamping means 11 by the same method as described above.

  The materials of the first and second clamping means 10 and 11 and the connecting means 14 are not particularly limited as long as these connected bodies function as plate springs. Specifically, for example, iron, stainless steel, hard plastic, and the like can be suitably used. In addition, even if these are formed of a conductive material such as iron, the operator holds the energy storage connector holding tool 1 of the present invention with an indirect hot wire gripping tool (not shown), so that insulation is ensured, There will be no problems such as electric shock.

  As shown in FIG. 1, the first and second picking means 15 and 16 are formed separately from the first and second holding means 10 and 11, respectively. The first and second holding means It is formed in a strip shape longer than the length in the front-rear direction of 10 and 11. The lengths of the first and second picking means 15 and 16 are such that the rear end sides of the first and second picking means 15 and 16 can be gripped by the indirect hot wire gripping tool in the forward and rearward direction. There is no particular limitation as long as the sides can be opened in a direction away from each other against the urging force of the plate spring, and can be set as appropriate. Preferably, the operator preferably opens the distal end side of the first and second clamping means 10 and 11 with the smallest operating force according to the principle of the lever, so that each of the first and second clamping means 10 and 11 can be opened. It is preferable that the length is about 2 to 3 times the length along the front-rear direction. The widths of the first and second knobs 15 and 16 are set to such an extent that they can be reliably gripped by an indirect live wire gripping tool. It is good to set it slightly larger than the distance between the opening edge part which faces the inward facing of the axial support parts 12, 12;

  Incisions 15a, 15b; 16a, 16b are provided on the edges of the first and second knobs 15, 16 near the both side edges in the width direction, respectively. By the cuts 15a and 15b, the distal end side of the first picking means 15 is partitioned into rod-like parts 15d and 15d that form both side edges with the intermediate part 15c, and the distal end side of the second picking means 16 is also cut by the cuts 16a and 16b. The intermediate portion 16c is partitioned into rod-like portions 16d and 16d that form both side edges. The rod-shaped portions 15d, 15d; 16d, 16d extend to the distal end side in parallel to the length direction of the first and second knobs 15, 16, respectively, and the distal ends of the respective rod-shaped portions are substantially perpendicular to them. The first and second knobs 15 and 16 are bent outward in the width direction, and support shafts 17 and 17 and 18 and 18 each having a circular cross section are formed in pairs. The support shafts 17 and 17 and the support shafts 18 and 18 are configured such that the axes of the support shafts are arranged on the same straight line.

  Since the width of the first picking means 15 is set slightly larger than the distance between the opening ends of the first pinching means 10 facing inwardly of the shaft support parts 12, 12, the tip side of the rod-like parts 15 d, 15 d is The support shafts 17 and 17 are fitted into the openings of the shaft support portions 12 and 12 of the first clamping means 10 in a state where they are bent in directions approaching each other. Further, the width of the second knob means 16 is set to be slightly larger than the distance between the opening ends facing inward of the shaft support portions 13 and 13 of the second clamping means 11, similarly to the first knob means 15. Therefore, the support shafts 18 and 18 are fitted into the openings of the shaft support portions 13 and 13 in a state where the distal ends of the rod-shaped portions 16d and 16d are bent in a direction approaching each other. As a result, the first knobs 15 and 16 are pivotally supported by the pivotal support portions 12 and 12; and 13 and 13, respectively, and are connected so as to rotate around the axial centers of the support shafts 17 and 17; The rod-like portions 15d, 15d; 16d, 16d are elastically returned to their original positions, so that the first picking means 15, 16 are not pivoted by themselves while being fixed to the shaft support portions 12, 12. . In this case, as shown in FIG. 1 (b) and FIG. 1 (c), the first and The two picking means 15 and 16 can be prevented from rotating so as to be in a predetermined direction.

  The rotation restricting means 19 is provided at the tip of the intermediate portion 15 c in the first picking means 15. FIG. 2 is an explanatory view showing the structure and operation of the rotation restricting means in the embodiment shown in FIG. As shown in this figure, the rotation restricting means 19 includes a rotation restricting surface 23 erected substantially perpendicularly outward from the front end edge of the intermediate portion 15c. Between the one end of the rotation restricting surface 23 projecting outward and a predetermined position on the outer surface of the intermediate portion 15c in the first knob 15, these are connected at an acute angle to the outer surface of the intermediate portion 15c. A connecting surface is formed. From the inner surface of the intermediate portion 15c (the surface on the first clamping means 10 side), a bulging portion 22 that bulges inward is formed in the cut 10a of the first clamping means 10, and this bulging portion 22 It is connected to the other end of the rotation restricting surface 23 on the front end side. The bulging portion 22 has a curved contact that contacts the sandwiched surface 43a of the head 41 of the accumulator connector body 40 in parallel with the length direction of the first picking means 15 through the notch 10a of the first sandwiching means 10. A contact surface 22 is formed.

  After clamping the head 41 of the accumulator connector body 40 by the first and second clamping means 10, 11, the first knob 15 is moved from the parallel position along the first clamping means 10 to the support shaft 17, By rotating the first picking means 15 around the 17 axis, the abutting surface 22 is in contact with the sandwiched surface 43a of the head 41, and the sandwiched surface 43a is rotated. The rotation restricting surface 23 comes into contact with the sandwiched surface 43a at a position where the first knob 15 is substantially vertical. Thereby, the rotation of the first picking means 15 is restricted, and the first picking means 15 is maintained in a direction substantially perpendicular to the sandwiched surface 43a.

  The material of the first picking means 15 and the second picking means 16 having such a rotation restricting means 19 is not particularly limited. For example, the same material as that of the plate-like spring-shaped first clamping means 10 and 11 is used. It can be formed by things.

At this time, in the cross section parallel to the front-rear direction of the rotation restricting means 19, the triangles ΔOKM, ΔOMP, and ΔOPR having the axis O of the support shaft 17 as the apex and the contact surfaces 22a to 22c as the bases are respectively Consists of isosceles triangles with the same shape inscribed in a virtual circle whose radius is the length of the line segment OK (OK = OM = OP = OR), and each hypotenuse from the axis O and the axis O The following relationship holds between the length of the perpendicular drawn on the base of the triangle.

このような関係により、図４の状態から、第１摘み手段１５を図中の矢印の方向に被挟持面４３ａに対して３０°ごと回動させるに当たっては（当接面２２ｂが被挟持面４３ａに当接し、６０°回動させることで、当接面２２ｃが被挟持面に当接し、さらに被挟持面４３ａに対して９０°回動させることで、回動規制面２３が被挟持面４３ａに当接する）、それぞれ斜辺−垂線の長さ分だけねじりコイルバネ２７の付勢力に抗して第１挟持手段１０および第１摘み手段１５を押し上げる必要がある。これにより、本実施形態の回動規制手段１９では、回動規制面２３によって第１摘み手段１５を被挟持面４３ａに対して直角な位置でその回動を規制できるだけでなく、３０°、６０°のそれぞれの位置に維持することもできるようになる。

Due to such a relationship, when the first knob 15 is rotated from the state of FIG. 4 by 30 ° with respect to the sandwiched surface 43a in the direction of the arrow in the figure (the contact surface 22b is the sandwiched surface 43a). The contact surface 22c is in contact with the sandwiched surface by rotating by 60 °, and is further rotated by 90 ° with respect to the sandwiched surface 43a so that the rotation regulating surface 23 is sandwiched by the sandwiched surface 43a. It is necessary to push up the first clamping means 10 and the first picking means 15 against the urging force of the torsion coil spring 27 by the length of the hypotenuse-perpendicular line. Thereby, in the rotation restricting means 19 of the present embodiment, not only the rotation of the first picking means 15 at a position perpendicular to the sandwiched surface 43a can be restricted by the rotation restricting surface 23, but also 30 °, 60 ° It can also be maintained at each position of °.

  The rotation restricting means 19 and the first picking means 15 including the rotation restricting means 19 are not particularly limited in material, but can be formed of the same material as the first and second clamping means 10 and 11. .

  The power storage connector holding tool of the present invention may be newly manufactured. However, since the structure has two holding means and a knob means, and one knob means is provided with a rotation restricting means, for example, a document A clip (or a double clip) that is commonly used for binding a pin, etc., can be used and modified so as to provide a rotation restricting means on one of the two picking means. There is an advantage that the production of the tool is simplified and the production cost is very advantageous.

[Usage Method of Power Storage Connector Clamp of the Present Invention]
Next, referring to FIG. 5 to FIG. 7, when replacing the pole transformer or the like, a new electric wire is distributed as a high voltage underline by an indirect hot wire method with the high voltage overhead distribution line being charged. Taking the case of connecting to the exposed conductor portion as an example, a method of using the energy storage connector holding tool of the present invention will be described. The power storage connector clamps 1 and 2 of the two embodiments both have substantially the same structure and function and can be used in the same manner. Therefore, in the following, the power storage connector of the embodiment shown in FIG. The usage method of the clamping tool 1 is demonstrated. In using the power storage connector holding tool 1 of the present invention, the covering of the end of a new electric wire (high voltage underline) W2 is peeled off in advance, and the exposed conductor is substantially parallel to the exposed conductor portion of the distribution line. Thus, it is assumed that these two electric wires W1 and W2 are fixed by tongues at positions that do not hinder the connection work of these conductors (slightly away from the conductor portion).

  The connection work of the two high-voltage wires is usually performed by two workers. First, a direction in which one worker directly picks the first and second pinching means 15 and 16 of the power storage connector holding tool 1 and separates the distal ends of the first and second holding means 10 and 11 from each other. The head 41 of the energy storage connector main body 40 is clamped by the opened first and second clamping means 10 and 11.

  In this state, the first knob 15 is rotated and maintained in a direction substantially perpendicular to the sandwiched surface of the head 41 of the accumulator connector body 40, as shown in FIG. The first picking means 15 is picked by a pair of gripping pieces 80 and 81 provided at the tip of a Yatco (not shown). Next, the power storage connector holding tool 1 is moved while the first knob 15 is being picked up by the Yatsuko, and both the conductors aligned in parallel of the two high voltage electric wires are accommodated in the space 44 of the power storage connector main body 40. As shown in FIG. While holding the first picking means 15 of the power storage connector holding tool 1 with a yam, this time, the nut 48 is picked with a pair of gripping pieces 82 and 83 of another yatco (not shown), and the arrow in FIG. From the direction, this is brought close to the screw portions 42b and 43b of the accumulator connector body 40, and the other screw is operated so that the inner screw of the nut 48 is engaged with the screw portions 42b and 43b by about one or two threads. To.

  Next, as shown in FIG. 7, the Yatco is operated, and the accumulator connector clamp 1 is further moved in the direction of the arrow in FIG. Is rotated while twisting so that the direction of the accumulator connector body 40 is substantially horizontal. The other operator operates the operating rod with the indirect ratchet 85 attached to the tip, and the nut 48 of the indirect ratchet 85 is engaged with the nut 48 slightly screwed into the screw portions 42b and 43b of the accumulator connector body 40. The nut 48 is screwed onto the accumulator connector body 40 and the conductors 60 and 61 of the two high-voltage electric wires W1 and W2 are tightened together. Securely fix. In FIG. 7, the energy storage connector main body 40 faces in a substantially horizontal direction. However, the present invention is not limited to this, and another worker operates the yatco to screw the screw portion 42 b of the energy storage connector main body 40. , 43b may be directed to a position where the nut 48 can be easily screwed.

  As described above, the power storage connector holding tool of the present invention can reliably hold a small power storage connector that has been difficult to grip with an indirect live wire gripping tool such as a conventional Yatsuko. No safety problems such as dropping of the power storage connector occur. In addition, it comprises at least a first knob means that is pivotally connected to the first clamping means, and a rotation restricting means that restricts the rotation of the first picking means. Since the operator can hold the accumulator connector at a position away from the tip of the gripping tool via the first picking means, the operator can efficiently connect the two high-voltage wires while confirming the direction of the accumulator connector. In addition, since the force accumulation connector holding tool of the present invention includes the rotation restricting means, the direction of the force accumulation connector body can be changed to a position where the nut to the force accumulation connector body can be easily screwed. As a result, the operation of connecting the two high-voltage electric wires using the accumulator connector by the indirect hot wire operation can be performed more efficiently.

  The power storage connector holding tool of the present invention is not limited to use in restoration work such as a pole transformer as described above, and it is not necessary to directly grip the power storage connector itself. It is also effective to make it easier to screw the nut into the accumulator connector by twisting the high-voltage electric wire, and to install a high-voltage underline in the overhead distribution line, such as when installing a new column with a pole-mounted transformer It is also applicable to cases.
