JP 2008-178201 A No. 7-13193

  However, as shown in Patent Document 1, when a wrapping terminal board is used as a terminal board of an intermediate wiring board, the wrapping terminal board is arranged in parallel in the vertical and horizontal directions with a small number of terminal pins spaced apart from each other. In connection with this, the jumper wire usually has a configuration in which a plurality of jumper wires are converged while the tip end side thereof can be wrapped around each terminal pin.

  For this reason, the wire stripping tool shown in Patent Document 1 and the wire stripper shown in Patent Document 2 are designed to remove the coating material one by one from the jumper wire. Since it is necessary to carry out the jumping work and the lapping work on the terminal pins of the wrapping terminal board one by one, depending on the number of jumper wires that connect the wrapping connection tool and the wire stripping tool or wire stripper. The operation of connecting the jumper wires to the terminal pins of the wrapping terminal board may become complicated.

  On the other hand, it is conceivable to peel off and remove the covering material from the tip of the jumper wire in advance, but in this case, the jumper wire is peeled off on the tip side and connected to the jumper wire that has not yet been wrapped. Inadvertent contact with the terminal pins other than the target terminal pin may cause contact and cause conduction, leading to unforeseen failures such as line communication failures in the wrapping terminal board and consequently the intermediate wiring board. There is.

  In addition, at least in the electric wire peeler described in Patent Document 2, no measures are taken against the peeling debris of the covering material peeled off from the electric wires scattered in the work site around the intermediate wiring board, There is also a problem that it is necessary to clean the collected waste material after the work is completed.

  Accordingly, the present invention relates to a converging body in which a plurality of wire rods, each of which has a conductive core material covered with a coating material, and which is branched depending on the number of wire rods that are focused on the front end side, have a tip portion for each wire rod. In order to peel off the coating material and connect this tip to the terminal of the intermediate wiring board, it is not necessary to change the equipment, and even in such a configuration, it is collected to remove the peeling material of the coating material after the work is completed. An object of the present invention is to provide an auxiliary tool for separating / connecting a coating material of a wire that does not need to be performed.

  The wire material covering / peeling work assisting / combining instrument according to the present invention has a plurality of wires that cover the periphery of a conductive core material with a coating material, and the number of wires whose front end side is focused. A plurality of through-holes that can be used for branching converging bodies, into which a branched portion of the wire rod can be inserted into the internal space portion, are formed in the housing having the internal space portion. The hole has a smaller inner diameter as it advances from the outside toward the inner space portion side, and the inner space portion has a coating for peeling the covering material on the side along the axial direction with respect to the through hole. A material peeling mechanism is housed, and further, a range in which the covering material is peeled off by the covering material peeling mechanism is defined on the side along the axial direction of the through hole that is farther from the through hole than the covering material peeling mechanism. Peeling range regulating member for storing Is further inserted jumper wire from the hole is characterized by being retained in said space portion (claim 1). The housing is formed of a transparent material, and it is visually confirmed whether the wire inserted into the internal space of the housing through the through hole is inserted until the tip of the wire contacts the peeling range defining member. It may be possible. Further, the wire material is, for example, a jumper wire, more specifically, a jumper wire for wrapping connection to a terminal pin of a wrapping terminal plate of an intermediate wiring board for communication. Further, temporary adhesion means such as magnets, suction cups, and adhesive tapes are provided on the outer surface of the housing, and the temporary adhesion means temporarily adheres to the surface of the attachment object such as the outer surface of the intermediate wiring board. Be able to. Furthermore, it is preferable that the peeling range defining member can move in any direction along the axial direction of the through hole.

  According to the configuration of the covering material peeling / connecting work auxiliary instrument, the tip side of all the wires branched from the converging body is inserted into the internal space portion from the through holes and held in the internal space portion, for example, Adhering to the outer surface of the intermediate wiring board, etc., only the wire material to be wrapped is pulled out from the through hole, and the coating material is peeled off by the coating material peeling mechanism at the leading end portion of the wire material at that time, so the lapping connection device as it is And proceed to a wrapping connection. In addition, the insertion / extraction operation of the wire rod is performed in accordance with this rule by standardizing the order of insertion of the covering material peeling / connection operation auxiliary tool into the through hole and the order of extraction from the through hole based on a predetermined standard. By doing so, it is possible to reduce an accident in which the wire is erroneously connected to a terminal other than the target terminal during the wrapping connection. Moreover, it is possible to accurately match the range of the covering material to be peeled off from the wire only by inserting the wire until it hits the peeling range defining member.

  And the covering material peeling / connecting work auxiliary instrument for wire according to the present invention is characterized in that the casing is provided with an opening / closing portion for opening / closing an opening communicating with the internal space portion (Claim 2). . As a result, the covering material peeling residue formed by peeling the covering material from the wire by the covering material peeling mechanism is stored in the internal space of the housing, and the collected covering material peeling residue is opened to open and close the opening. Can be disposed of at the disposal site.

  The covering material peeling mechanism is composed of a pair of blade-like members that are symmetrically arranged with respect to the axis of the through hole and that each swing in a direction along the axial direction of the through hole. The blade members are biased by an elastic mechanism in a direction approaching each other, and even when the tips of both blade members are closest to each other, the gap is the same as the diameter of the core of the wire rod. The same or slightly larger dimensions may be set (claim 3). The biasing force of the elastic mechanism can be adjusted by changing the tension.

  According to such a configuration of the covering material peeling mechanism, when a wire is inserted from the through hole toward the peeling range defining member, the blade member is pushed by the wire and swings toward the peeling range defining member. After the operation of inserting until the wire rod hits the peeling range defining member is completed, the tip of the blade member is covered with the coating material of the wire rod and the core material by the urging force of the elastic mechanism. The wire is held in the internal space of the housing. Then, when the wire is pulled out from the insertion hole, the tip side portion of the wire remains in the internal space part as the peeling material is peeled off from the portion where the blade-like member is inserted to the peeling range defining member side. Then, the core material is exposed and comes out of the housing.

  On the other hand, the covering material peeling mechanism is composed of a pair of blade-like members that are arranged symmetrically with respect to the axis of the through hole and at least one of which operates in a direction that is closer to the axis of the through hole. The gap when the tips of both blade-like members are closest to each other may be set to a size that is the same as or slightly larger than the diameter of the core of the wire (Claim 4).

  According to such a configuration of the covering material peeling mechanism, after inserting the wire from the through hole toward the peeling range defining member until it abuts against the peeling range defining member, at least one of the blade-like members is formed in the through hole. By operating in the direction approaching the axis, the tips of both blade members are inserted up to the boundary between the wire covering and core, so when the wire is pulled out from the insertion hole, the blade member is inserted into the wire. The coating material in the range on the peeling range defining member side is peeled off from the part, and the core material is exposed at the tip end portion while leaving the inside of the internal space as a peeling residue, and comes out of the housing.

  In this case, a wire holding mechanism that holds the wire when the wire is pulled out to the through hole side in the internal space between the covering material peeling mechanism and the peeling range defining member. (Claim 5). Thereby, it is possible to execute the insertion of the end sides of all the wires branched from the converging body through the through holes into the internal space portion and hold them in the internal space portion.

  As described above, according to the present invention, the leading end side of all the wires branched from the converging body is inserted into the internal space through the through holes and held in the internal space, for example, on the outer surface of the intermediate wiring board, etc. Only the wire to be lapped and connected is pulled out from the through hole. At that time, the coating material is peeled off from the tip of the wire by the coating material peeling mechanism. Since it is possible to proceed to the wrapping connection, there is no need to switch between the wrapping connection device and the device for stripping the coating material of the wire material, so it is possible to simplify and speed up the entire wire wrapping connection work. It becomes.

  Further, according to the present invention, the order of insertion into the through-hole of the covering material peeling / connecting work assisting / use tool and the order of withdrawal from the through-hole are made regular based on a predetermined standard, and in accordance with this rule. By inserting and pulling out wire rods, it is possible to reduce accidents in which wire rods are mistakenly connected to terminals other than the target terminal during wrapping connection, so it is possible to assist in wrapping connection work of wire rods. .

  Furthermore, according to the present invention, it is possible to accurately match the range of the covering material to be peeled off from the wire by only inserting the wire until it hits the peeling range defining member. It is possible to simplify and speed up the work for peeling off. In addition, by allowing the peeling range defining member to move along the axial direction of the wire in a state where it is mounted in the internal space of the housing, the peeling range of the covering material can be optimized by the amount of movement of the peeling range defining member. Can be specified.

  In particular, according to the invention described in claim 2, the covering material peeling debris formed by peeling the covering material from the wire by the covering material peeling mechanism is stored in the internal space of the housing, and the accumulated covering material is peeled off. Since the scrap can be discarded from the opening to the disposal site by opening the opening and closing part, the scrap of the covering material from the wire is prevented from being scattered at the work site for connecting the wire, and is covered after the wire is connected. Eliminates the need to clean up material scraps.

  In particular, according to the invention described in claim 3, with respect to the covering material peeling mechanism, by inserting the wire from the through hole toward the peeling range defining member, the blade member is pushed toward the peeling range defining member by being pushed by the wire. After the work to be swung and inserted until the wire comes into contact with the separation range defining member is completed, the tip of the blade-like member is attached to the wire covering material because the urging force of the elastic mechanism tries to return to the original position. Since it is inserted to the boundary part with the core material, the wire material is held in the internal space of the housing, and when the wire material is pulled out from the insertion hole, the wire material extends from the part where the blade member is inserted to the peeling range defining member side. The coating material in the range is peeled off and remains in the internal space as a peeling residue, and the core material is exposed at the tip side and comes out of the housing. Whether to hold the wire in the internal space and wire You can have the functions of both the release function of the dressing.

  In particular, according to the invention described in claim 4, after the wire material is inserted from the through hole toward the peeling range defining member until it abuts against the peeling range defining member, at least of the blade-like members. By operating one side in the direction approaching the axis of the through hole, the tips of both blade members are inserted to the boundary between the wire covering and core material. The covering material in the range on the peeling range defining member side is peeled off from the portion where the shaped member is inserted, and is left as a peeling residue in the internal space, and the core material is exposed on the tip side and comes out of the housing Therefore, the peeling function of the coating material from the wire can be sufficiently ensured.

  In particular, according to the invention described in claim 5, the wire holding mechanism can be inserted into the internal space through the front end side of all the wires branched from the converging body and held in the internal space, A function of holding the wire rod in the internal space of the housing can be sufficiently secured.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  In FIG. 1, a schematic configuration of the intermediate wiring board 1 is shown. The intermediate wiring board 1 is, for example, a communication line concentrating board. The intermediate wiring board 1 is a main wiring board installed in a telephone station, an apartment house, an office (not shown), a communication device 2 in the telephone station, a communication device 3, etc., and a modular of each door. It relays between terminal devices 4 such as a jack. In this embodiment, the intermediate wiring board 1 is provided with a wrapping terminal board 5 on the front side and a terminal board 6 not particularly limited on the back side. The wrapping terminal board 5 has a large number of terminal pins 7. The terminals 8 are arranged in parallel vertically and horizontally with a slight space therebetween, and the terminals 8 are also arranged in parallel on the terminal board 6 vertically and horizontally.

  Each terminal pin 7 of the wrapping terminal board 5 of the intermediate wiring board 1 is electrically connected to one side of the main wiring board and the jumper wire 11 of the focusing body 10 by wrapping connection. The converging body 10 has a plurality of jumper wires 11 (six in this embodiment) converging, and its tip end is finally branched according to the number of each jumper wire 11. As shown in FIG. 2, the wire 11 has a configuration in which the entire circumference of a conductive core material 12 such as metal is covered with a coating material 13 made of a non-conductor such as resin. Examples of the converging body 10 include those converging so that the jumper wires 11 are knitted together and those converging by inserting all the jumper wires 11 into the cylindrical member. In the terminal board 6 of the intermediate wiring board 1, the terminal 8 and the communication devices 2 and 3 and the terminal 14 of the terminal device 4 are electrically connected via the wire 15.

  2 to 5 show a first embodiment of the wire material peeling / connection assisting instrument 17 according to the present invention.

  As shown in FIGS. 2 and 3, the wire material peeling / connection assisting instrument 17 is mainly composed of a housing 18 having an internal space 19, and the housing 18 is made of, for example, a transparent material. The covering material peeling mechanism 21 and the peeling range defining member 27, which will be described later, can be recognized even from the outside of the housing 18.

  Further, as shown in FIG. 2, the housing 18 is provided with as many through holes 20 as the number of jumper wires 11 branched from the focusing body 10 (six in this embodiment). . These through holes 20 are for inserting the jumper wires 11 into the internal space 19, and one side is open to the outer surface of the housing 18 and the other side communicates with the internal space 19. As shown in FIG. 3, the inner diameter dimension is the largest at the opening side end with respect to the outer surface of the casing 18, and the inner diameter dimension is the largest on the side communicating with the inner space portion 19. The inner diameter dimension becomes narrower as it goes to the space 19 side. However, the inner diameter dimension on the side communicating with the internal space portion 19 is slightly larger than the outer diameter dimension of the jumper wire 11. By adopting such a shape of the through hole 20, it is easy to insert the jumper wire 11 from the through hole 20 into the internal space 19. In this embodiment, the through hole 20 is formed by bending the outer wall portion of the housing 18 into the inner space portion 19 as shown in FIG. 3, but the present invention is not necessarily limited thereto. The outer wall portion 18 may be thickened, and the outer wall portion may be formed by making a through hole 20 in the outer wall portion.

  Further, the housing 18 has a bonding means such as a magnet or an adhesive tape (not shown), and can be temporarily bonded to the intermediate wiring board 1 or the like using this bonding means. As shown in FIG. 2, the housing 18 has an annular portion 16. When the casing 18 cannot be bonded by an adhesive means, for example, the intermediate wiring board 1 is passed through the annular portion 16 through a string or the like. You can also hang it on. Further, as shown in FIG. 2, the housing 18 has, for example, an opening 33 on the side wall and an opening / closing part 34 that opens and closes the opening 33. The position of the opening 33 is preferably located closer to the annular portion 16 than the coating material peeling mechanism 21 described later.

  And the coating | covering material peeling mechanism 21 is accommodated in the axial direction (insertion direction of the jumper wire 11) of the through-hole 20 in the internal space part 19 of the housing | casing 18. FIG. As shown in FIGS. 3 and 5, the covering material peeling mechanism 21 urges the blade member 22 that swings in the axial direction of the through hole 20 and the blade member 22 toward the through hole 20. An elastic mechanism 23 that applies an urging force and a stopper 24 that restricts a swinging range of the urging force of the elastic mechanism 23 toward the through hole 20 are configured.

  The blade-like members 22 and 22 are arranged at positions symmetrical with respect to the reference line when a line extending in the axial direction of the through hole 20 is used as the reference line. The blade members 22, 22 have a rotating shaft 25, which is installed in the inner space 19 by having both ends mounted between walls extending along the axial direction of the jumper wire 11 in the casing 18. The blade is swingable by being inserted into the blade and becomes a sharp blade that extends along the radial direction of the jumper wire 11 while being narrowed for a while as it advances toward the tip.

  In this embodiment, the stopper 24 is integrally formed with the housing 18 and extends obliquely from the inner surface of the housing 18 toward the side opposite to the through hole 20 side. The blade-like member 22 can come into contact with the surface.

  For example, a helical coil spring is used for the elastic mechanism 23, one end is fixed to a wall of the housing 18 that intersects the wall to which the blade member 22 is attached, and the other end is fixed to the blade member 22. As a result, the blade member 22 is constantly urged to press toward the through hole 20, and the magnitude of the urging force is such that the blade member 22 contacts the stopper 24 in normal times. The blade member 22 is set so as to be separated from the stopper 24 by a pressing force when the jumper wire 11 is inserted while being in contact with each other. And the magnitude | size of the urging | biasing force to this blade-shaped member 22 can be adjusted by changing the tension | tensile_strength of the elastic mechanism 23 via the tension | tensile_strength apparatus which is not shown in figure. When both the blade members 22 abut against the stopper 24, a gap is opened between the tips of the blade members 22 as shown in FIG. The dimension L1 of the gap between them is the same as or slightly larger than the outer diameter of the core material 12 of the jumper wire 11.

  Thereby, as shown in the arrow direction of FIG. 5B, when a line along the axial direction of the through hole 20 is used as a reference line, the direction away from the reference line (on the diagram of FIG. 5B, When the jumper wire 11 abuts against the abutment plate 27b of the peeling range defining member 27 and the insertion of the jumper wire 11 is completed after the rocking in the clockwise direction), the direction shown by the arrow in FIG. As described above, the tip of the elastic mechanism 23 is inserted into the jumper wire 11 so as to return to the original position. Further, when the jumper wire 11 is pulled out of the housing 18 through the through hole 20, the jumper wire 11 peels off the covering material 12 in a range from the portion where the blade-like members 22, 22 are inserted to the separation range defining member 27 side. As a result, the core 13 is exposed at the tip end portion and leaves the housing 18 through the insertion hole 20 while remaining in the internal space 19 as the peeling residue 12a.

  A peeling range defining member 27 is accommodated in the internal space 19 of the housing 18 at a position farther from the through hole 20 than the coating material peeling mechanism 21 in the axial direction of the through hole 20. As shown in FIGS. 3, 4, and 5, the peeling range defining member 27 includes a pedestal 27 a extending along the axial direction of the through hole 20, and an abutting plate 27 b extending in a direction perpendicular to the pedestal 27 a. The abutting plate 27b protrudes from the pedestal 27a into the internal space 19 so that the tip of the jumper wire 11 inserted from the through hole 20 can be abutted. .

  The peeling range defining member 27 is movable in the internal space 19 along the axial direction of the through-hole 20, and an example of a mechanism for moving the peeling range defining member 27 is mainly shown in FIGS. And shown in That is, a plurality of rack portions 28 formed with a plurality of irregularities on the surface of the pedestal 27a of the peeling range defining member 27 facing the housing 18 are provided along the axial direction of the through hole 20 (two in this embodiment). A rack portion 29 is formed on the surface facing the pedestal 27a of the housing 18 and formed with irregularities that can mesh with the gear portion 28 at a position corresponding to the rack portion 28 of the pedestal 27a. ing. An operation member 30 extending in the direction opposite to the through hole 20 along the axial direction of the through hole 20 is formed on the surface of the standing plate 27b opposite to the through hole 20 side. As shown in FIG. 2, the member 30 protrudes from the opening 31 to the outside of the housing 18, and an elastic member 32 such as rubber is interposed between the inner peripheral surface of the opening 31 and the operation member 30. Thus, the operation member 30 is held by the elastic member 32 and is not pushed or pulled in the axial direction of the through-hole 20 in an inadvertent operation.

  Accordingly, the pedestal of the separation range defining member 27 is obtained by holding the operation member 30 and pushing it toward the through hole 20 along the axial direction of the through hole 20 or by pulling it away from the through hole 20 side. The unevenness of the rack portion 28 of 27 a moves along the axial direction of the through hole 20 while meshing with the unevenness of the rack portion 29 of the housing 18, and the position where the pedestal 27 a is stopped can be maintained. For this reason, since the dimension until the jumper wire 11 inserted from the through hole 20 abuts against the abutment plate 27b of the separation range defining member 27 can be varied, the blade-like member 22 of the covering material separation mechanism 21 can be changed. It is possible to easily, accurately and finely define the dimension from the tip of the metal plate to the abutting plate 27b, that is, the range in which the covering material 12 is peeled from the jumper wire 11.

  The holding of the jumper wire 11 and the peeling of the covering material 12 from the jumper wire 11 will be described using the wire material peeling / connection auxiliary instrument 17.

  First, after operating the operating member 30 to determine the position of the peeling range defining member 27, the jumper wire 11 is moved from the through hole 20 of the housing 18 into the internal space 19 and the abutting plate 27b of the peeling range defining member 27 is placed. When the blade member 22 is inserted until it hits, the blade member 22 of the covering material peeling mechanism 21 swings in the opening direction with respect to the jumper wire 11 as shown by the arrow direction in FIG. When the jumper wire 11 abuts against the abutting plate 27b of the peeling range defining member 27 and the insertion of the jumper wire 11 is completed, as shown in the arrow direction of FIG. The tips of both blade-like members 22 are inserted into and sandwiched by the jumper wire 11. For this reason, since the jumper wire 11 is held in the internal space portion 19, the jumper wire 11 branched from the other focusing body 10 is similarly connected to the internal space portion of the housing 18 from each through hole 20. By being inserted into 19, the entire focusing body 10 is held by the wire peeling / connection assisting instrument 17 as a whole. Therefore, by attaching the wire separating / connecting auxiliary instrument 17 to the intermediate wiring board 1 or the like with an adhesive means or hanging the annular part 28 with a string or the like, both hands of the operator can be made free.

  Next, when holding the wrapping connection device (not shown) with one hand and pulling out the jumper wire 11 from the through-hole 20 of the wire peeling / connection assisting instrument 17 with an open hand, as shown in FIG. In addition, the jumper wire 11 is peeled off from the portion where the blade-like members 22 and 22 are inserted to the peeling range defining member 27 side to be peeled off as a peeling waste 12a. The core material 13 is exposed at the tip end portion and remains out of the housing 18 through the insertion hole 20, so that the wrapping connection can proceed as it is. Therefore, it is not necessary to change the wrapping connection device. Moreover, when the debris 12a has accumulated to some extent, the opening / closing part 34 can be opened and discarded from the opening 33 to the disposal site, so that the debris 12a is not scattered at the work site of the lapping connection, and the debris 12a Therefore, it is not necessary to perform cleaning to collect the peeling residue 12 and it is easy to discard the peeling residue 12.

  FIG. 6 shows a second embodiment of the wire material peeling / connection assisting instrument 17 according to the present invention. The second embodiment will be described below with reference to FIG. However, the configuration of the casing 18 having the internal space 19, the through hole 20 formed in the casing 18, and the peeling range defining member 27 accommodated in the internal space 19 of the casing 18 is the same as in the first embodiment. 6 is denoted by the same reference numerals as those in the first embodiment, and the description thereof is omitted.

  The wire peeling / connection assisting / combining instrument 17 shown in the second embodiment includes a coating material peeling mechanism 21 having a configuration different from that of the first embodiment. The covering material peeling mechanism 21 has a main portion housed in the axial direction of the through hole 20 (in the insertion direction of the jumper wire 11) in the internal space 19 of the housing 18, and the axial direction of the through hole 20. When a line extending to the reference line is used as a reference line, two blade members 36 and 37 are arranged at positions symmetrical to the reference line, and one blade member 36 is fixed in the casing 18. At the same time, the other blade-like member 37 can move in a direction closer to the blade-like member 36.

  An example of a push button mechanism 39 is shown in FIG. 6 as a mechanism for moving the blade member 37 in a direction moving away from the blade member 36. The push button mechanism 39 includes a push button 40, a transition portion 41, an elastic member 42, a box portion 44, a lock device 45, and a release device 46.

  Among these, the push button 40 and the transition part 41 are integrally formed, and the transition part 41 extends from the central part of the surface facing the casing 18 of the push button 40. A blade-like member 37 is provided at the tip of 41. The elastic member 42 is, for example, a spiral coil spring or the like, and one side abuts on the lower end of the transition part 41 and the other abuts on the bottom surface of the box part 44, and faces the transition part 41 to the outside of the housing 18. And has an urging force to press. The box portion 44 has a through-hole 43 through which the blade-like member 37 is inserted in the bottom surface and accommodates the lock device 45. One end of the locking device 45 is inserted into the side wall of the box portion 44, and the other end can be brought into contact with the upper surface of the protruding portion 47 protruding in the radial direction from the transition portion 41 and is inserted into the box portion 44. A lever 48 that can be buckled in a direction far and away from the protrusion 47 as shown in the direction of the dashed line arrow in both FIGS. Has been. When the other end of the lever 48 is in contact with the upper side of the protrusion 47 of the transition portion 41, the transition portion 41 is close to the bottom of the box portion 44 against the urging force of the elastic member 42. Can be held. The release device 46 is composed of a pin 49 inserted from the outside of the housing 18 toward the lever 48, and by pushing this pin 49, the lever 48 can be pushed down at the tip of the pin 49. .

  6A, the blade member 36 and the blade member 37 are separated from each other, and the lever 48 is in contact with the lower surface of the protrusion 47 of the transition portion 41. When the push button 40 is pushed in the direction of the white arrow in FIG. 6A, the projection 47 of the transition portion 41 pushes the lever 48 so that the lever 48 is seated in the direction of the one-dot chain line in FIG. At the same time, the tip of the transition portion 41 moves downward to compress the elastic member 42. Then, since the protrusion 47 of the transition portion 41 is also relatively lower, a restoring force acts on the lever 48, and the end portion of the lever 48 becomes the protrusion 47 of the transition portion 41 as shown in FIG. It will be in the state which touched the upper side. For this reason, since the restoring force of the elastic member 42 is regulated by the pressing by the lever 48 of the locking device 45, the state where the transition part 41 approaches the lower surface of the box part 44 is maintained and fixed. The blade member 37 provided at the tip of the blade passes through the through hole 43 and approaches the blade member 36, and the blade members 36 and 37 are inserted into the jumper wire 11. Further, when the pin 49 is pressed, the state where the transition part 41 approaches the lower surface of the box part 44 is released, and the blade member 37 is separated from the blade member 36 side.

  A holding device 51 for holding the jumper wire 11 in the internal space 19 of the housing 18 is provided at a position farther from the through hole 20 than the push button mechanism 39. The holding device 51 includes, for example, sandwiching members 52 and 53 that swing in the axial direction of the through hole 20, and an elastic mechanism 54 that applies a biasing force that biases the sandwiching members 52 and 53 toward the through hole 20. It consists of and.

  The clamping members 52 and 53 are arranged at positions symmetrical with respect to the reference line when a line extending in the axial direction of the through hole 20 is used as the reference line. The sandwiching members 52 and 53 have a rotation shaft 55 that extends across the interior space 19 by attaching both ends between the walls extending along the axial direction of the jumper wire 11 in the casing 18. The tip is rounded or a relatively soft material is used so that it does not get damaged even if the jumper wire 11 is sandwiched between them.

  For example, a helical coil spring is used for the elastic mechanism 54, and one end is fixed to a wall of the housing 18 that intersects the wall to which the clamping members 52 and 53 are attached, and the other end is the clamping member 52. , 53 is always biased so as to press the clamping members 52, 53 toward the through-hole 20 side, and the magnitude of the biasing force is determined when the jumper wire 11 is inserted. The clamping members 52 and 53 are set so as to be separated from the stopper 24 by the pressing force. And the magnitude | size of the urging | biasing force to this member 52, 53 for clamping can be adjusted by changing the tension | tensile_strength of the elastic mechanism 23 via the tension | tensile_strength apparatus which is not shown in figure.

  The holding of the jumper wire 11 and the peeling of the covering material 12 from the jumper wire 11 will be described using the wire material peeling / connection auxiliary instrument 17.

  First, after operating the operating member 30 to determine the position of the peeling range defining member 27, the jumper wire 11 is moved from the through hole 20 of the housing 18 into the internal space 19 and the abutting plate 27b of the peeling range defining member 27 is placed. When it is inserted until it abuts, the holding members 52 and 53 of the holding device 51 swing in the opening direction with respect to the jumper wire 11 as shown by the arrow direction in FIG. When the jumper wire 11 abuts against the abutment plate 27b of the peeling range defining member 27 and the insertion of the jumper wire 11 is completed, as shown in the arrow direction of FIG. Since it returns, the jumper wire 11 is clamped by the clamping members 52 and 53. For this reason, since the jumper wire 11 is held in the internal space portion 19, the jumper wire 11 branched from the other focusing body 10 is similarly connected to the internal space portion of the housing 18 from each through hole 20. By being inserted into 19, the entire focusing body 10 is held by the wire peeling / connection assisting instrument 17 as a whole. Therefore, by attaching the wire separating / connecting auxiliary instrument 17 to the intermediate wiring board 1 or the like with an adhesive means or hanging the annular part 28 with a string or the like, both hands of the operator can be made free.

  Next, when holding the lapping connection device (not shown) with one hand and pulling out the jumper wire 11 from the through-hole 20 of the wire peeling / connection assisting / combining instrument 17 with an open hand, as shown in FIG. 6B. Further, the jumper wire 11 is peeled from the covering material 12 in a range from the portion where the blade-like members 22 and 22 are inserted to the peeling range defining member 27 side to become a peeling residue 12a. The core material 13 is exposed at the tip end portion and remains out of the housing 18 through the insertion hole 20, so that the wrapping connection can proceed as it is. Therefore, it is not necessary to change the wrapping connection device. Moreover, when the debris 12a has accumulated to some extent, the opening / closing part 34 can be opened and discarded from the opening 33 to the disposal site, so that the debris 12a is not scattered at the work site of the lapping connection, and the debris 12a Therefore, it is not necessary to perform cleaning to collect the peeling residue 12 and it is easy to discard the peeling residue 12.
