  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. FIGS. 1-12 is a figure which shows one Embodiment of the sleeve compression apparatus assembled with the connection adapter based on this invention.

  1, the connection adapter 10 is used when connecting the gripping tool YATCO 100 shown in FIG. 2 and the compression tool compression pliers (manufactured by Nippon FCI Co., Ltd.) 200 shown in FIG. As shown in FIG. 4, the connecting sleeve S sheathed on the core wire d of the electric wire D held by the YATCO 100 can be compressed with the compression pliers 200 and can be easily connected to the electric wire D.

  Here, as shown in FIG. 2, the Yatco 100 holds the object by gripping the object by transmitting the operating force via the gripping part 101 for gripping the object, the support bar 102 gripped and supported by the operator, and the transmission bar 103. And a handle 104 for operating the unit 101. The gripping portion 101 of this Yatco 100 has a bifurcated bendable stationary member 101a fixed to the support rod 102, and a curved movable member 101b connected to the transmission rod 103 is bifurcated. The member 101a is pivotally supported around a rotation shaft 101c.

  As a result, the YATCO 100 can rotate the movable member 101b relative to the stationary member 101a of the grasping portion 101 by operating the handle 104, and the bending inner surface of the stationary member 101a and the bending of the movable member 101b. An object or the like can be grasped between the inner surfaces. The Yatco 100 includes an umbrella cover 105 that drips moisture from the gripping side and an umbrella cover 106 that indicates a limit position where the work can be safely performed in consideration of insulation from the gripping side. The whole is made of an insulating material such as a plastic or rubber material, thereby ensuring insulation.

  As shown in FIG. 3, the compression pliers 200 are manual compression pliers, and are connected to a connection member 201 that is connected to a support member that is gripped by an operator and the connection member 201 in an immovable posture. A stationary member 202, a pivoting member 203 having one end pivotably supported on the top of the stationary member 202, and a rear end pivotally supported by the other end of the pivoting member 203. In addition, the intermediate portion can be freely rotated from the intermediate portion of the stationary member 202 to the distal end portion of the supporting member 202a that protrudes in the opposite direction of the connecting member 201. A transmission member 205 that is supported and whose upper part is rotatably connected to an intermediate part of the pulling member 204, and a lower part that is rotatably supported on the opposite side of the lower connecting member 201 of the stationary member 202. In addition, a compression member 206 whose upper part is rotatably connected to the lower part of the transmission member 205, and a lowermost compression part of the compression member 206 which is disposed at the lowermost part of the stationary member 202 and is rotated in the proximity direction. And a receiving member 207 that causes the receiving portion 207a to face the 206a. Here, the vertical relationship in the description of the present embodiment is described by matching the vertical direction of the drawing, and does not mean the vertical relationship in actual use, including the compression pliers 200, and is understood. The top and bottom are temporarily attached so that it is easy to do.

  Thus, when the compression pliers 200 pull the ring member 204a at the tip of the pulling member 204 downward in the drawing, the pulling member 204 rotates around the upper portion of the intermediate transmission member 205, thereby rotating. The member 203 is driven and rotated, and the transmission member 205 is driven and rotated in the direction in which the transmission member 205 approaches the non-moving member 202. As a result, the compression pliers 200 pull the pulling member 204 of the long member by causing the compression member 206 to approach the receiving portion 207a of the receiving member 207 by rotating the transmission member 205. The compression sleeve 206a of the compression member 206 having a short distance to the rotation center is rotated by the traction force, and the connection sleeve S positioned between the receiving portion 207a is compressed and deformed by the pressure contact force that increases the traction force. Can do. The compression pliers 200 are restricted from returning backward by a ratchet mechanism (not shown). However, the compression pliers 200 are released from the restriction by the compression operation that brings the compression portion 206a and the receiving portion 207a closest to each other. The return spring 208 between the moving members 203 can return to the initial state, and when the compression operation is to be stopped, the reverse return restriction is released by pulling the ring member 205a of the transmission member 205 to the non-moving member 202 side. To return to the initial state.

  The compression pliers 200 are designed so that one end portion 201a of the connecting member 201 can be connected and connected to the mating member by a star structure, and generally, for example, a star adapter as shown in FIG. By connecting and attaching to the tip of the insulating operating rod 400 shown in FIG. 6 through 300, the operator can take the insulating operating rod 400 and take it to a remote working position. Has been.

  As shown in FIG. 5, the Kikuza adapter 300 has a head portion 301 connected and connected to one end 201 a of the connecting member 201, and a joint portion 311 connected and connected to the tip of the insulating operation rod 400 at both ends of the rod shape. Has been.

  First, the connecting member 201 of the compression pliers 200 is formed in a disk shape having a connecting groove 201b whose one end 201a opens in a U shape from the tip to the inside, and one surface side of the one end 201a. A plurality of projections (not shown) projecting radially around the bottom of the connecting groove 201b are formed in the circumferential direction (similar shape to the head portion 301 of the Kikuza adapter 300).

  On the other hand, the head portion 301 of the Kikuza adapter 300 is formed in a disc shape that can face the disc-shaped one end portion 201 a of the connecting member 201, and a butterfly female is located at the center of one surface side of the head portion 301. A plurality of protrusions that are erected from a male screw 303 that engages with the screw 304 and that protrude radially from the male screw 303 (center of one surface side) and continue in the circumferential direction, like the one end 201a of the connecting member 201. 302 is formed.

  As a result, the head 301 of the Kikuza adapter 300 inserts the male screw 303 into the connecting groove 201b of the one end 201a of the connecting member 201 so that the disk shape is in contact with each other so that the butterfly female screw 304 is in contact with the male screw. By being screwed onto 303 and tightened, the protrusions 302 can be engaged with each other, and the engagement position can be rotated relative to each other to have an arbitrary relative angle so that the insulating operation rod 400 can be in a desired posture. Thus, the compression pliers 200 can be connected and connected.

  Further, the joint portion 311 of the Kikuza adapter 300 is formed in a bottomed cylindrical shape in which the rear end surface of the base end portion is open so that the distal end portion of the insulating operation rod 400 can be inserted, and the cylindrical portions are mutually connected. The opposite peripheral surface is cut into a substantially T-shape, so that the insertion notch 313 from the rear end face (operation bar 400) side toward the front end side and both sides of the insertion notch 313 in the orthogonal direction are provided. A pair of engagement notches 314 that refract so as to be continuous are formed.

  On the other hand, as shown in FIG. 6, the insulating operating rod 400 is provided in a projecting shape on the side surfaces opposite to each other at the tip portion so that the inside of the two cutout portions 313 and 314 of the joint portion 311. A pin 401 that can be inserted into and engaged with, a protrusion 402 that is disposed on the tip surface of the tip portion and is biased in a protruding direction by a built-in spring (not shown), and is carved on the side surface of the tip portion.

  As a result, the insulating operating rod 400 inserts the tip portion into the joint portion 311 of the Kikuza adapter 300 and sinks the protrusion 402 against the elastic force of the built-in spring, while holding both pins 401 of the joint portion 311. After entering and rotating into the notches 313 and 314 and releasing the force to enter, the protrusion 402 protrudes due to the elastic force of the spring and pushes out the joint 311 to be refracted from the engagement notch 314. The pin 401 can be engaged with the engaging groove 314a so as not to be detached. Further, the insulating operation rod 400 can be locked so that the pin 401 is not detached from the engagement groove 314a and rotated by rotating the grip 403 and moving it toward the joint 311 side. It is possible to prevent the seat adapter 300) from being relatively rotated and detached and to make it easy to handle. Here, the insulating operating rod 400 is provided with umbrella covers 405 and 406 in the middle part, and the whole is made of an insulating material such as plastic, so that insulation is ensured. The cover 405 drips moisture from the side of the compression pliers 200, and the umbrella cover 406 on the proximal end side indicates a limit position where the work can be safely performed, thereby ensuring safety when working.

  Further, the insulation operating rod 400 is prepared so that the hook 500 of the tip tool shown in FIG. 7 can be connected and connected to the tip. As shown in FIG. Similar to the Kikuza adapter 300, a key portion 501 is fixed to the joint portion 311. As a result, the insulation operating rod 400 is connected to the tip of the joint portion 311 of the hook 500, and the ring member at the tip of the pulling member 204 of the remote compression pliers 200 connected to the tip of the separate insulation control rod 400. It is possible to perform an operation of hooking and pulling the tip 502 of the key portion 501 on 204a.

  Returning to FIG. 1, the connection adapter 10 is attached to the attachment portion 11 attached to the cylindrical portion 111 for connecting and fixing the grip portion 101 to the tip of the support rod 102 of the YATCO 100, and one end portion 201 a of the connection member 201 of the compression pliers 200. A Kikuza part 21 connected and connected by a Kikuza structure, and a connecting part 31 that connects the mounting part 11 and the Kikusa part 21 are provided. That is, the connecting adapter 10 forms the gripping side mounting portion with the mounting portion 11 and also forms the compression side mounting portion with the chrysanthemum portion 21, whereby the mounting portion 11 and the chrysanthemum portion 21 are connected via the connecting portion 31. It is designed so that the relative position and the relative posture of each have a predetermined relationship.

  The attachment part 11 is a cylinder part 12a, 12b obtained by dividing the plate-like semicylindrical shape into two parts so that the cylindrical part 111 of the grip part 101 of the YATCO 100 can be accommodated, and one end side of the cylindrical part 12a, 12b is relatively rotated A rotating shaft 13 that freely connects and supports the internal storage space so as to be openable and closable, and facing portions 14a and 14b that face the other ends of the cylindrical portions 12a and 12b are provided. As shown in FIG. 8, the male screw portion 15 a of the butterfly male screw 15 is inserted into a through hole (not shown) that opens in the center of the facing portions 14 a and 14 b and screwed so as to be tightened. The cylindrical portion 111 of 101 can be attached and fixed in a tightened state.

  On the other hand, since the cylindrical portion 111 of the grip portion 101 of the YATCO 100 is fixed by a pin 111a that penetrates the tip of the support rod 102, the attachment portion 11 of the connection adapter 10 is located between the facing portions 14a and 14b. The cylindrical portions 12a and 12b can be attached so that they do not deviate around the cylindrical portion 111 in the circumferential direction by positioning the end portion of the pin 111a protruding in a protruding manner on the opposite side of the circumferential direction. The mounting direction can be selected by rotating the facing portions 14a and 14b by 180 degrees using the two pins 111a located.

  Similarly to the head portion 301 of the general-purpose Kikuza adapter 300, the Kikuza portion 21 is formed in a disc shape that can face the disc-shaped one end portion 201a of the connecting member 201 of the compression pliers 200. A male screw 23 to be engaged with the butterfly female screw 24 is erected at the center, and a plurality of projections 22 that protrude radially from the male screw 23 (center on one surface side) and are continuous in the circumferential direction are formed. In addition, the mark 25 indicating the position of the U-shaped connecting groove 201b opened at the one end 201a when the one end 201a of the connecting member 201 of the compression pliers 200 is faced to the seat 21. By forming and connecting the one end portion 201a at a relative angle at which the mark 25 can be seen, the relative position and the relative posture of the compression pliers 200 (the connecting member 201 of the compression pliers 200) are made desirable as described later. be able to.

  As a result, the male seat portion 21 inserts the male screw 23 into the connecting groove 201b of the one end portion 201a of the connecting member 201 of the compression pliers 200 so that the disk shapes are in contact with each other, and the butterfly male screw 24 is connected to the male screw 24. By screwing and tightening to the screw 23, the protrusions 22 can be engaged and engaged with each other. As will be described later, the engagement engagement is performed at a relative angle at which the mark 25 is exposed from the connecting groove 201b on the compression pliers 200 side. By combining, the compression pliers 200 can be connected and connected to the YATCO 100 attached by the attachment portion 11 of the connection adapter 10 so as to have a desired posture.

  The connecting portion 31 includes a base end portion 26 extending so as to be separated from the disk shape on which the projection 22 of the chrysanthemum portion 21 is formed. A plate-like portion 32 extending in a direction parallel to the disk-shaped plane of the portion 21 is provided. The connecting portion 31 is fixed so that the base end portion 26 is positioned on one end portion side of the one surface side of the plate-like portion 32, and the cylindrical portion 12 b of the attachment portion 11 has an axial direction in the chrysanthemum portion 21. It is positioned so as to be positioned on the other side of the other surface side of the plate-like portion 32 in a posture that is positioned on the back surface side of the seat structure and is parallel to the extending direction of the plate-like portion 32. In addition, the connecting portion 31 has a female screw 31 a that is screwed with the male screw portion 15 a of the butterfly male screw 15 of the mounting portion 11 formed in the plate-like portion 32. And this connection part 31 adjusts the dimension of the plate-shaped part 32 with the dimension of the base end part 26 of the chrysanthemum part 21, and the refractive inner surface of the stationary member 101a of the holding part 101 of the YATCO 100 and the movable member 101b The core wire d of the electric wire D gripped between the curved inner surfaces is designed so as to be positioned on the receiving portion 207a approaching the compression portion 206a of the compression pliers 200.

  By designing in such a structure, the connection adapter 10 accommodates the cylindrical portion 111 of the grip portion 101 of the Yatco 100 in the cylindrical portions 12a and 12b of the mounting portion 11, as shown in FIGS. By tightening with the butterfly male screw 15 while facing the facing portions 14a and 14b in the state, it can be attached and connected to the tip of the support rod 102 of the YATCO 100. At the same time, the connection adapter 10 engages and engages the one end 201a of the connection member 201 of the compression pliers 200 with the relative angle at which the mark 25 is exposed from the connection groove 201b. Thus, the core wire d of the electric wire D gripped by the gripping portion 101 of the Yatco 100 can be set to be positioned on the receiving portion 207a of the compression pliers 200.

  As a result, the function of the grip part 101 (grip tool part), the function of the compression pliers 200 (compression tool part), and the support of the yatco 100 can be achieved simply by connecting the yatco 100 and the compression pliers 200 with the connecting adapter 10. It is possible to construct a device having the function (supporting part) of the rod 102 and the function (gripping operation part) by the transmission bar 103 and the handle 104 of the YATCO 100, and in addition, an insulation operation with the hook 500 attached to the tip. By configuring the sleeve compression device with the function of the bar 400 (remote control unit), the Y-co 100 is operated to grip the electric wire D, and the compression pliers 200 at the end of the Y-co 100 are connected to the hook 500 at the end of the insulating operation bar 400. By simply operating the cable, the connecting sleeve S sheathed around the core d of the remote electric wire D is compressed into the electric wire D. It is possible to perform the work to continue.

  Therefore, as shown in FIG. 11, the gripping portion 101 of the sleeve compression device 1000 holds and supports the electric wire D1 at a remote position such as a high place, and the compression pliers 200 are insulated operation rods 400 with hooks 500. , The one end side of the connection sleeve S sheathed on the core d of the electric wire D1 can be compressed and connected to the electric wire D1. After that, the core wire d of the electric wire D2 gripped by a separate general-purpose YATCO 2000 is supported by being installed inside the other end side of the connection sleeve S, and the grip portion 101 of the YATCO 100 of the sleeve compression device 1000 is supported. After the gripping position of the electric wire D1 is shifted, the compression pliers 200 are operated with an insulating operation rod 400 with a hook 500 to compress the other end side of the connecting sleeve S that houses the core wire d of the electric wire D2, and the electric wire Can be connected to D2.

  Therefore, the connection work of the electric wires D1 and D2 at remote locations such as high places is performed by operating the YATCO 100 of the sleeve compression apparatus 1000 and the insulating operation rod 400 with the hook 500 and the separate general-purpose YATCO 2000. It can be easily performed by two persons with the operator, and the separate YATCO 2000 only needs to be operated at the time of compression connection on the other end side of the connection sleeve S. That is, conventionally, as shown in FIG. 12, the operator who supports and operates the compression pliers 200 connected to the tip of the insulating operation rod 400 and the electric wire D1 which is compressed and connected to one end of the connection sleeve S are gripped by the YATCO 2000. And three workers, the operator holding the wire D2 compressed and connected to the other end of the connection sleeve S with the YATCO 2000, and the wires D1 and D2 (connection sleeve S for connection) ) And the operator who supports and operates the compression pliers 200, it is difficult to synchronize the timing, and if the work is not performed carefully, a connection error may occur, and it takes a considerable amount of time. However, the same operation by these can be completed easily and in a short time.

  Although the work shown in FIG. 12 can be performed by two people, in this case, two wires D1 and D2 that are compression-connected to one end side and the other end side of the connection sleeve S are connected to two Yattcos. It is necessary to operate and hold 2000, and a considerable level of skill and skill are required. In addition, the insulating operation rod 400 and Yatco 2000 cross each other and workability is deteriorated. Even in this respect, it is advantageous to use the sleeve compression apparatus 1000 according to the present embodiment.

  Thus, in this embodiment, the core wire d of the electric wire D and the connection sleeve S can be positioned and held in common, and the compression connection work can be performed. The position of the electric wire D to be held and the compression position of the connection sleeve S can be performed. The compression connection can be easily performed without adjusting the above. Therefore, even at a remote location such as a high place, the work of compressing and connecting the electric wire D by the connection sleeve S can be easily performed, and the connecting operation of the electric wire D can be efficiently completed without taking work time. it can.
