The die support member 107 is attached. A plurality of fixed dies 105 having different compression diameters are attached to the die support member 107. In the compression pliers 100, the diameter of compression by the fixed die 105 can be switched by rotating the die support member 107.

  The movable arm 102 swings like a seesaw around the fulcrum 106. One end and the other end of the movable arm 102 move in opposite directions as the movable arm 102 swings. That is, when one end of the movable arm 102 approaches the fixed arm 101, the other end of the movable arm 102 is separated from the fixed arm 101, and when one end of the movable arm 102 is separated from the fixed arm 101, the other end of the movable arm 102 is fixed to the fixed arm 101. To approach.

  In the movable arm 102, a movable die 108 is provided at one end on the fixed die 105 side. The movable die 108 is displaced in the direction of contacting and separating from the fixed die 105 as the movable arm 102 swings with respect to the fixed arm 101. In the edge connecting work, in the compression pliers 100, a sleeve (see reference numeral 502 in FIG. 5 and the like) is disposed between the fixed die 105 and the movable die 108, and the movable die 108 is brought closer to the fixed die 105. Thus, the sleeve is compressed between the fixed die 105 and the movable die 108.

  The swing arm 103 is connected to the movable arm 102 at the end of the movable arm 102 opposite to the movable die 108. The swing arm 103 is rotatable with respect to the movable arm 102 and swings integrally with the swing of the movable arm 102 with respect to the fixed arm 101. In this embodiment, the swing member according to the present invention can be realized by the movable arm 102 and the swing arm 103 connected to the movable arm 102.

  The fixed arm 101 and the swing arm 103 are connected to each other via a link member 109 and a bell crank 110 at the end opposite to the side connected to the movable arm 102. One end of the link member 109 is rotatably connected to the fixed arm 101 at the end of the fixed arm 101. The other end of the link member 109 is rotatably connected to one end of the bell crank 110 between the end of the fixed arm 101 and the end of the swing arm 103.

  An urging member such as a torsion spring may be provided at a connection position between the link member 109 and the bell crank 110. In this case, one end of the torsion spring is fixed to the link member 109, the other end is fixed to the bell crank 110, and the link member 109 and the bell crank 110 are urged in the opening direction.

  The bell crank 110 is bent into a substantially “<” shape, and includes a long arm 110 a extending from the bent portion in one direction and a short arm 110 b extending from the bent portion in another direction. The bell crank 110 is rotatably connected to the other end of the link member 109 at the tip of the short arm 110b. Further, the bell crank 110 is rotatably connected to the end of the swing arm 103 at the bent portion.

  In the bell crank 110, a socket connecting portion 111 is connected to the end of the long arm 110a. The socket connecting portion 111 is rotatably connected to the bell crank 110. The socket connecting part 111 has a bottomed cylindrical shape with an open end. A guide groove 111 a having a substantially T-shape is formed on the peripheral surface of the socket connecting portion 111.

  Each of the guide grooves 111a has a substantially T shape, and locking portions 111b are formed at both ends. The guide groove 111a is provided at two locations on the peripheral side surface of the socket coupling portion 111 at opposing positions (positions where the phase is shifted by 180 degrees). The socket connecting portion 111 is connected to the common operating rod connecting portion (see reference numeral 306 in FIG. 3).

  In this embodiment, the operating member according to the present invention can be realized by the long arm 110a. Further, in this embodiment, the connected portion according to the present invention can be realized by the socket connecting portion 111.

  The connecting arm 104 extends substantially parallel to the fixed arm 101 and is fixed to the fixed arm 101 at one end via a pair of support members 112 having a flat plate shape. The support member 112 protrudes on the same side of the fixed arm 101 as the side on which the movable arm 102 and the swing arm 103 are provided. The support member 112 is attached to the fixed arm 101 so as to sandwich the movable arm 102. The movable arm 102 is rotatable with respect to the fixed arm 101 between the support members 112. The length of the support member 112 in the protruding direction is set to a length that does not interfere with the rotation range of the movable arm 102.

  The other end of the connecting arm 104 has a bifurcated shape and is provided with a chrysanthemum seat. A socket connecting portion (see reference numeral 401 in FIG. 4) having the same configuration as that of the socket connecting portion 111 is connected to one end of the connecting arm 104 via a star seat. In this embodiment, the connection arm 104 and the socket connection portion provided at one end of the connection arm 104 can realize the member connected to the connection portion of the common operation rod according to the present invention.

  During edge connection work, with the position of the connecting arm 104 fixed, the socket connecting portion 111 is pulled downward (see arrow A in FIG. 1) via the common operation bar connected to the swing arm 103. Then, the sleeve (see symbol B in FIG. 1) into which the electric wires are inserted from both ends is compressed.

(Composition of common operation bar)
Next, the configuration of the common operation rod used for the edge connection work using the compression pliers 100 according to the embodiment of the present invention will be described. FIG. 3 is an explanatory diagram showing the configuration of the common operation bar. In FIG. 3, the common operation bar 301 includes an elongated bar-shaped member 302. The rod-shaped member 302 includes a plurality of hooks 303 provided at midway positions in the length direction. One end side of the rod-like member 302 is subjected to anti-slip processing, and is gripped by an operator during edge connection work.

  The other end of the rod-shaped member 302 is provided with a connecting portion 306 including a protrusion 304 protruding in the axial direction of the rod-shaped member 302 and a pair of pins 305 protruding in the opposite direction from the outer peripheral surface of the rod-shaped member 302. It has been. The pair of pins 305 are each biased in a direction protruding from the outer peripheral surface of the rod-shaped member 302 by a biasing member (not shown) such as a compression spring provided inside the rod-shaped member 302. The joint portion of the common operation rod according to the present invention can be realized by the other end of the rod-shaped member 302 provided with the protrusion 304 and the pair of pins 305.

(Ring connection work procedure)
Next, a work procedure of edge connection work using the compression pliers 100 according to the embodiment of the present invention will be described. 4, 5, and 6 are explanatory diagrams showing the work procedure of the edge connecting work using the compression pliers 100 according to the embodiment of the present invention.

  In the edge connection work using the compression pliers 100 according to the embodiment of the present invention, the worker first connects the compression pliers 100 and the common operation rod 301 (see FIG. 4). Specifically, the connection between the compression pliers 100 and the common operation rod 301 is performed by connecting the connection portion 306 of the common operation rod 301 to the socket connection portion 111 in the swing arm 103 and the socket connection portion 401 in the connection arm 104, respectively. This is done by connecting.

  Next, an operator approaches a connection location (refer FIG. 5). Specifically, the approach to the connection location is as follows. An operator grips the common operation rod 301 and brings the fixed die 105 and the movable die 108 in the compression pliers 100 closer to the connection location, and the fixed die 105 and the movable die 108 are connected. This is done by positioning the connection portion between them and aligning the compression position by the compression pliers 100 with the position to be compressed in the sleeve. The connection location is the outer peripheral surface of the sleeve 502 in which the ends of the two electric wires 501 to be connected are inserted from both ends.

  Then, the worker performs compression at the time when the position of compression by the compression pliers 100 matches the position of the sleeve 502 to be compressed (see FIG. 6). The compression is performed by pulling the common operation bar 301 connected to the swing arm 103 downward (see reference numeral A in FIG. 6) in a state where the position of the common operation bar 301 connected to the connection arm 104 is fixed. .

  As a result, the movable arm 102 rotates in the direction in which the movable die 108 approaches the fixed die 105 via the swing arm 103, and the fixed die 105 and the movable die 108 approach each other. As a result, the sleeve 502 can be compressed between the fixed die 105 and the movable die 108.

  As described above, according to the edge connecting operation using the compression pliers 100 according to the embodiment of the present invention, the compression is immediately performed when the compression position by the compression pliers 100 and the position to be compressed in the sleeve 502 are matched. Can be done.

(Construction of conventional compression pliers)
FIG. 7 is an explanatory diagram showing a configuration of a conventional compression pliers. In FIG. 7, the same parts as those of the compression pliers 100 of the embodiment according to the present invention are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 7, in the conventional compression pliers 700, the connecting arm 104 is provided on the opposite side of the fixed arm 101 from the side on which the movable arm 102 and the swing arm 103 are provided. That is, in the conventional compression pliers 700, the fixed arm 101 is positioned between the connecting arm 104, the movable arm 102 and the swing arm 103.

  A conventional compression pliers 700 includes an operation ring 701 provided at the tip of a long arm 110a. The operation ring 701 has an annular shape, and can hook a hook-shaped member such as a bind hitter.

(Work procedure of edge connection work using conventional compression pliers 700)
Next, the work procedure of the edge connection work using the conventional compression pliers 700 will be described. 8, 9, 10, and 11 are explanatory diagrams illustrating edge connection work using a conventional compression pliers 700.

  In the edge connection work using the conventional compression pliers 700 described above, the worker first connects the fixed arm 101 and the common operation rod 301 in the compression pliers 700. Then, the operator grasps the common operation rod 301 and approaches the connection portion so that the operation ring 701 exceeds the electric wire 501 to be connected (see FIG. 8). In addition, the operator grasps the common operation rod 301 to which the bind hammer 801 is attached at the tip, and the common operation rod 301 supports the compression pliers 700 with the electric wire 501 interposed therebetween. Let the other side wait.

  Next, a bind hammer 801 attached to the tip of another common operation rod 301 is put over the electric wire 501 to be connected (see FIG. 9). Thereby, a ring is formed by the worker (both arms of the worker), the common operation rod 301, the conventional compression pliers 700, and another common operation rod 301. The electric wire 501 to be connected is located inside this ring.

  Next, with the electric wire 501 positioned inside the ring formed by the worker (both arms of the worker), the common operation rod 301, the conventional compression pliers 700, and another common operation rod 301, The fixed die 105 and the movable die 108 in the compression pliers 100 are brought close to the connection location, the connection location is positioned between the fixed die 105 and the movable die 108, and the position between the compression position by the compression pliers 100 and the compressed position in the sleeve 502 is determined. (See FIG. 10).

  Thereafter, the operator performs compression when the position of the compression pliers 100 and the position to be compressed in the sleeve 502 are matched (see FIG. 11). In the edge connecting operation using the conventional compression pliers 700, the sleeve 502 is compressed by sandwiching the sleeve 502 between the two common operation rods 301.

  As described above, in the edge connection work using the conventional compression pliers 700, the operator holds the common operation rod 301 coupled to the fixed arm 101 in a posture in which the operation ring exceeds the electric wire to be connected. The bind hammer 801 must be put over the wire. For this reason, the operator works in a posture in which the compression position is looked up from below, and the display of the compression location of the sleeve 502 is difficult to see. For this reason, the above-described various problems occur, and it takes time to complete the compression, and there is a problem that the burden on the operator is large.

  On the other hand, in the edge connection work using the compression pliers 100 according to the embodiment of the present invention, the common operation bar 301 and another common operation bar 301 are located on the same side with respect to the compression position. The person's standing position is not limited to just below the compression position. For this reason, the operator can make the compression pliers 100 approach the compression position from a position where the visibility of the compression position can be secured satisfactorily, and can perform alignment easily and in a short time.

  In the edge connecting operation using the compression pliers 100 according to the embodiment of the present invention, the compression is immediately performed when the compression position by the compression pliers 100 and the position to be compressed in the sleeve 502 are matched. Therefore, from the completion of alignment to the completion of compression can be performed in a short time.

  Thereby, the edge connection work using the compression pliers 100 according to the embodiment of the present invention can be completed in a shorter time than the edge connection work using the conventional compression pliers 700. Then, by completing the compression in a short time, the burden on the operator can be reduced as compared with the edge connection work using the conventional compression pliers 700.

  Further, since the compression can be performed immediately when the positions are matched, the compression can be performed with high accuracy. In addition, since the compression can be performed immediately when the positions are adjusted, the time during which the electric wire is simply inserted without being compressed by the sleeve 502 can be shortened. It is possible to prevent the position from being displaced or the electric wire from being removed from the sleeve 502. As a result, the burden on the operator can be reduced as compared with the edge connection work using the conventional compression pliers 700.

  12 and 13 are explanatory diagrams schematically showing a compression structure in the compression pliers 100. FIG. As shown in FIG. 12 and FIG. 13, at the time of edge connection work, the coating of the ends of the two electric wires 501 to be connected is peeled off to expose the conductor 1201. In FIG. 12, the electric wire 501 connected to the transformer (Tr) side is inserted into the sleeve 502 from the end on the right side of the page, and the electric wire 501 connected to the overhead line side is inserted from the end on the left side of the page. It shows the state to do. The coating is peeled from the tip of the electric wire 501 by a predetermined length. Then, the exposed conductor 1201 is inserted from both ends of the sleeve 502, respectively.

  The compression pliers 100 according to the embodiment of the present invention are configured to compress two portions of the sleeve 502 in one compression operation. Specifically, the shapes of the fixed die 105 and the movable die 108 are adjusted so that two compression protrusions 1301 protrude from the fixed die 105 and the movable die 108, respectively. Thereby, since two places can be compressed by one compression operation, the edge connection work can be completed by the compression operation that is half the number of conventional operations.

  The compression pliers 100 according to the embodiment of the present invention includes a sleeve guide 1302 extending from the position of the compression protrusion 1301 in the direction of the rotational axis of the fixed arm 101, the movable arm 102, and the swing arm 103. It may be. The sleeve guide 1302 has a length that allows the compression protrusion 1301 to be positioned at an optimal compression position by aligning the tip of the sleeve guide 1302 with the end portion 1303 of the covering. Specifically, the length from the compression protrusion 1301 to the tip of the sleeve guide 1302 is adjusted. Thereby, it is possible to perform compression at an optimum position by utilizing the peeling of a predetermined length of the covering.

  In the above-described embodiment, the example in which the connected portion according to the present invention is realized by the socket connecting portion 111 has been described. However, the connected portion according to the present invention is not limited to that realized by the socket connecting portion. The coupled portion according to the present invention may be provided with a ring-shaped member or a hook-shaped member instead of the socket coupling portion.

  In this case, in the edge connection work, instead of another common operation rod 301, a bind hammer 801 is connected to the tip of the common operation rod 301, and the bind hammer 801 is hooked on a ring-shaped member or a hook-shaped member. In this state, the sleeve 502 may be compressed by attracting another common operation rod 301 to which the bind hammer 801 is connected.

  As described above, the compression pliers 100 of this embodiment that realizes the compression tool according to the present invention include the fixed arm 101 having an arm shape with a predetermined length and the fixed arm 101 provided at one end of the fixed arm 101. A die 105, and a swing arm 103 that is swingably connected to the fixed arm 101 via a fulcrum provided at an intermediate position on the fixed die 105 side of the center position in the length direction of the fixed arm 101; A movable die 108 provided at one end of the swing arm 103 on the fixed die 105 side and displaced in a direction of moving toward and away from the fixed die 105 as the swing arm 103 swings, and the other end of the swing arm 103 And a long arm 110a provided with a socket coupling portion 111 coupled to the coupling portion 306 of the common operation rod 301.

  The compression pliers 100 are further extended from the fixed arm 101 to the side of the fixed arm 101 to which the swing arm 103 is connected, and are connected to the connecting portion 306 of the common operation rod 301 at the extended tip. And a support member 112 that supports the socket connecting portion 401.

  According to the compression pliers 100 of the embodiment according to the present invention, since the common operation bar 301 and another common operation bar 301 are located on the same side with respect to the compression position, the standing position of the operator is limited. Therefore, the operator can work at a position where the visibility of the compression position can be ensured satisfactorily. Thereby, alignment can be performed easily and in a short time.

  Further, according to the compression pliers 100 of the embodiment of the present invention, the compression can be performed immediately when the positions of the compression position of the compression pliers 100 and the compressed position of the sleeve 502 are matched. Thereby, it is possible to perform in a short time from the completion of the alignment between the compression position by the compression pliers 100 and the position to be compressed in the sleeve 502 to the completion of the compression.

  Further, according to the compression pliers 100 of the embodiment according to the present invention, the operator can work at a position where the visibility of the compression position can be ensured satisfactorily. It can be accurately adjusted to the compression position. Thereby, it can compress easily and accurately in a short time.
