Description

  The present invention relates to an electric wire connection device, and more particularly, to an apparatus that allows a plurality of conductive wires to be easily conductively connected, and that the conductive connection can be easily eliminated and reused.

  Conventionally, when wires are connected to each other, an electrically conductive connection is performed by applying a compression sleeve to a conductive wire from which the coating has been peeled off and then crimping and bonding. For example, a separate wire is connected to an existing wire. When branching by connecting the conductors, the covering of the branch portion of the existing electric wire is peeled off and the tip of the branch electric wire is peeled off, and the conductive wires are joined together in a compression sleeve (compression terminal) having an O-shaped cross section. Conductive connection is established by pressure bonding (for example, see Patent Document 1).

  As another connection structure, there has also been proposed a compression terminal formed in an 8-shaped cross section so that the conductive wires of the existing electric wire and the branch electric wire can be accommodated respectively. In this compression terminal, the existing electric wire and the branch electric wire are provided. These conductive wires are housed in different housing holes each having an 8-shaped cross section and are separately connected by pressure bonding (for example, see Patent Document 2).

Further, when branching by connecting a plurality of branch wires to the main wire, for example, as shown in FIG. 9, electricity is distributed to each home or the like on the drawn down wire 107 connected to the low voltage side of the transformer 103 of the utility pole 101. 10 and 11, a branch box 110 containing a plurality of terminals T1 to T5 is attached to the arm metal 105 of the utility pole 101 and pulled to the terminal T5. The lower electric wire 107 is screwed and conductively connected, and the drawn electric wire is screwed and electrically connected to the terminals T1 to T4, whereby the drawn electric wire can be branched and connected to the lower electric wire 107 (for example, Patent Document 3). reference). 10 and 11, reference numeral 106 denotes a mounting bracket for attaching the branch box 110 to the arm metal 105 of the utility pole 101, and 112 denotes a screwing operation by exposing terminals T <b> 1 to T <b> 5 in the pull-in branch box 110. It is a cover that opens and closes when performing.

  However, in such a conventional wire connecting device, when a plurality of wires are branched to the main wire, the branch box 110 described in Document 3 may be used. As the number of lead-in wires branching out increases, the number of connected lead wires exceeds the terminal T prepared in the branch box 110, and the main wire pull-down wire 107 is separately prepared and the branch box 110 itself is added. There must be.

  Further, the branch box 110 is not prepared so that all types of electric wires can be connected to the terminal T. In such a case, the pull-down electric wires 107 are used by using the compression terminals described in the literatures 1 and 2. There is no choice but to connect the lead-in wire to the conductor. Such a compression terminal requires a dedicated tool, is cumbersome, and cannot be removed once it has been joined, so it cannot be reused and is no longer needed. Needs to cut or replace the drawn wire 107.

  Therefore, the present invention realizes an electric wire connection structure that can easily connect a plurality of conductive wires to each other and that can be removed for reuse and easily eliminate the conductive connection. For example, to provide an electric wire connecting device that can branch a main electric wire by appropriately connecting and branching a plurality of electric wires while reusing the main electric wire without cutting the main electric wire.

Therefore, the conductive wire can be separately inserted into the opening of the male screw member, and the conductive connection can be established without being affected by the pressure contact state of the other conductive wires.

  According to a fourth aspect of the electric wire connecting apparatus for solving the above-mentioned problems, in addition to the specific matter of any of the first to third aspects of the invention, the opening of the male screw member is an end side end surface of the male screw member. It is characterized by having an opening.

  In the present invention, the conductive wire can be accommodated in the opening from one end side or the other end side of the male screw member, and then the female screw member can be screwed into the male screw member. Therefore, it is possible to establish a conductive connection in a state of being inserted into the opening of the male screw member without cutting the existing conductive wire.

Therefore, the conductive wire can be brought into pressure contact with the inner surface of the male screw member in a stable state without being affected by the wire diameter, and can be conductively connected.

  According to a sixth aspect of the electric wire connecting apparatus for solving the above-mentioned problems, in addition to the specific matter of any of the first to fifth aspects of the invention, one or two or more sets of accommodating spaces of the male screw member and the female screw member are accommodated. It is equipped with a case that opens and closes by bringing the edges of the case member made of an insulating material into contact with each other, and the case member is held in pressure contact with a wire that is electrically connected by a male screw member and a female screw member.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-6 is a figure which shows 1st Embodiment of the electric wire connection apparatus based on this invention.

  In FIG. 1, the wire connecting device 10 includes a connecting portion 11 for each electric wire connected to the conductive wires 107 a and 108 a of the drawn down electric wire 107 and the drawn-in electric wire 108, and the drawn down electric wire 107 and the drawn-in electric wire connected together with the connecting portion 11. And a case 21 for housing 108, and a number of lead-in wires 108 corresponding to the number of households in each household that distributes electricity is connected to the low-voltage side of the transformer 103 of the utility pole 101 shown in FIG. By branching and connecting to the electric wire 107 via the connecting portion 11 and accommodated in the case 21, the electric pole 101 can be attached to and supported by the brace 105.

  As shown in FIG. 2, the connecting portion 11 is designed to be used by assembling a plurality of nuts (female screw members) 16 and 17 into a bolt (male screw member) 12. The bolt 12 and the nuts 16 and 17 are made of a metal material having excellent conductivity.

  The bolt 12 has a threaded portion 12a on the outer peripheral surface side where a screw thread is screwed to the nuts 16 and 17, and the diameter of the conductive wires 107a and 108a of the drawn down electric wire 107 and the drawn-in electric wire 108 to be connected. Is also cut out wide to form an opening 13 penetrating between the outer peripheral surfaces on both sides centered on the axis, and this opening 13 opens toward the outside also at one end face, It is formed in an opening shape extending from one end side to the tip end side (in the moving direction by screwing of the nuts 16 and 17).

  The bolt 12 is formed in a roof shape whose tip side is parallel to the penetrating direction of the opening 13 (direction perpendicular to the axis), and the tip-side inner surface (the inner surface of the roof-shaped portion 14) 13a of the opening 13 is It is formed in a valley shape (concave shape) recessed toward the tip side. Here, it goes without saying that the front end side inner surface 13a of the opening 13 is not limited to a valley shape having a flat slope, but may be formed in a concave shape that is recessed in a curved shape or the like.

  As a result, as shown in FIG. 3, the connecting portion 11 screwes the nut 16 into the bolt 12 and peels the outer cover between the nut 16 and the inner surface 13 a of the front end side of the opening 13 of the bolt 12. The conductive wire 108a of the lead-in electric wire 108 is inserted, and the nut 16 is screwed and rotated with the bolt 12, so that the one surface side of the nut 16 and the concave inner surface 13a of the opening 13 of the bolt 12 are connected. It is possible to make a pressure contact with the conductive wire 108a of the lead-in electric wire 108 in a stable posture, and to make a conductive connection reliably.

  In addition, the connecting portion 11 is inserted in parallel with the lead-in wire 108 by inserting the conductive wire 107a of the pull-down electric wire 107 continuously stripped from the opening on the one end side into the same opening 13 of the bolt 12 and inserting it. After making it into the state made into the state, by screwing the separate nut 17 to the bolt 12, the conductive wire 107a of the pull-down electric wire 107 can be directly pressed against the other surface side of the nut 16 which has been screwed previously. it can. That is, the bolt 12 can be brought into a state in which the conductive wire 107a or the like is inserted from the opening at one end thereof (without being cut), and the conductive wires 107a and 108a that are inserted into the opening 13 are formed. The connection restriction due to the diameter can be relaxed to be in a parallel state in the same space, and the conductive connection can be established via the nut 16 or the other nut 17 and the bolt 12.

  The tightening operation for pressing the conductive wire 108a of the lead-in electric wire 108 to the front end side inner surface 13a of the opening portion 13 of the bolt 12 with the nut 16 is performed by inserting the conductive wire 107a of the pull-down electric wire 107 into the opening portion 13 of the bolt 12 or the like. However, from the viewpoint of work space and instability, it is better to work first as in this embodiment.

  Therefore, as shown in FIG. 4, the electric wire connecting device 10 can peel off the outer sheath and appropriately connect the electric connection by the connecting portion 11 according to the number of the drawn electric wires 108 connected to the drawn electric wires 107.

  As shown in FIG. 5, the case 21 is produced, for example, by molding an insulating resin material into a substantially rectangular parallelepiped that can be divided into two pieces, and the end portions 22 a of the divided case member 22 are separated from each other. The plurality of sets of bolts 12 and nuts 16 and 17 (connection portion 11) for connecting a plurality of lead-in wires 108 to one pull-down wire 107 are accommodated together with the pull-down wires 107 and the lead-in wires 108. It is designed to form a space.

  The case member 22 is formed so that it can be divided into two on the substantially extended surface of the paralleled surface of the drawn down electric wires 107 and the plurality of drawn-in electric wires 108, and the end sides 22a are arranged on the long side. A hinge portion 23 is formed which is connected to a thin wall and can be opened and closed.

  As shown in FIG. 6, the case member 22 has a pleated member 24 extending in parallel from one side of the end side 22 a to the other side on the three sides other than the hinge portion 23. The pull-down electric wire 107 and the pull-in electric wire 108 are inserted between the pleat-shaped members 24 so as to be held between them. Here, in the present embodiment, a structure in which the pleated member 24 is arranged in parallel to the end side 22a of the case member 22 to position and hold the drawn-down electric wire 107 and the drawn-in electric wire 108 is adopted. Alternatively, an elastically deformable rubber material (elastic member) may be connected to the end side 22a so that the pull-down electric wire 107 and the pull-in electric wire 108 are sandwiched therebetween and held by the elastic force.

  In addition, the case member 22 has an engagement protrusion 26 erected on the other side of the end side 22a in the engagement hole 25a at the end of the extension piece 25 extending from one side of the end side 22a. By hooking, the end sides 22a are brought into contact with each other so that the bolt 12 and the nuts 16 and 17 (connection portion 11) can be closed in a state of being housed together with the pull-down electric wire 107 and the pull-in electric wire 108. .

  Therefore, the wire connecting device 10 covers the case 21 and covers the ends 22a of the case member 22 after appropriately connecting the plurality of lead-in wires 108 to the pull-down wire 107 through the plurality of connecting portions 11. By closing in this manner, the drawn down electric wire 107 and the drawn-in electric wire 108 can be moved between the pleat-shaped members 24 to be positioned and held. After that, for example, by winding the fixed electric wire 107 and the case 21 around the armor 105 with a bind wire or the like, the drawn electric wire 107 or the drawn electric wire 108 swings in the vicinity of the connecting portion 11 to concentrate stress. The operation of conducting and connecting a plurality of lead-in wires 108 to the pull-down wire 107 from the low-voltage side of the transformer 103 of the utility pole 101 can be completed without causing disconnection or the like.

  And when it is necessary to add the lead-in electric wire 108, as long as the capacity | capacitance of the lead-in electric wire 108 permits, it peels off the jacket of the same pull-in electric wire 107, and carries out the conductive connection of the lead-in electric wire 108 suitably by the connection part 11. When the inside of the case 21 is filled with the connecting portion 11, another case 21 can be prepared and attached in the same manner.

  On the other hand, when the lead-in wire 108 that is conductively connected to the pull-down wire 107 is no longer necessary, the nuts 16 and 17 screwed into the bolts 12 of the connecting portion 11 are rotated in the reverse direction to remove the outer cover. The recovery operation can be easily completed simply by applying an insulation treatment to the peeled portion, and the connecting portion 11 can also be reused.

  As described above, in the present embodiment, the conductive wires 107a and 108a of the pull-down electric wire 107 and the lead-in electric wire 108 can be electrically connected by simply tightening them with the bolts 12 and the nuts 16 and 17 of the connecting portion 11 and directly pressing them. Moreover, the connection part 11 can be removed from the conductive wires 107a and 108a only by loosening the tightening. Therefore, it can be used as a wire branching device for easily conducting and connecting a plurality of lead-in wires 108 to the drawn-down wire 107, and the conduction connection can be easily eliminated. The bolt 12 and the nuts 16 and 17 can be reused.

  Next, FIG.7 and FIG.8 is a figure which shows 2nd Embodiment of the electric wire connection apparatus based on this invention. Here, since this embodiment is configured in substantially the same manner as the first embodiment described above, the same components are denoted by the same reference numerals and the characteristic portions will be described.

  In FIG. 7, the connecting portion 11 of the wire connecting device 10 is assembled and used in a state in which a plurality of nuts (female screw members) 361 to 36 n (n is a natural number) are screwed to a bolt (male screw member) 32. The bolt 32 and the nuts 361 to 36n are made of a metal material having excellent conductivity.

  The bolt 32 has a plurality of insertion holes 33 and a plurality of insertion holes 34 formed at a plurality of locations in the screw portion 32a on the outer peripheral surface side where a screw thread to which the nuts 361 to 36n are screwed is formed. The insertion holes 33 and 34 are perforated larger than the diameters of the conductive wires 107a and 108a of the pull-down electric wire 107 to be connected and the lead-in electric wire 108 and penetrate between the outer peripheral surfaces on both sides centering on the axis. . The insertion hole 33 is formed so as to be wider than the conductive wire 107a of the pull-down electric wire 107 and is cut out so as to open toward the outside at one end face as well as the opening 13 of the above-described embodiment. The other insertion hole 34 is formed with a larger diameter than the conductive wire 108 a of the lead-in electric wire 108.

  The bolt 32 has a bottom surface 33a located on the opposite side of the opening on the one end side of the insertion hole 33 in a valley shape (concave shape), and the insertion hole 34 opens in a circular shape and is positioned on the bottom surface side. The inner surface 34a is also curved in an arc shape (concave shape).

  As a result, as shown in FIG. 8, the connection portion 11 closes the insertion holes 34 with the nuts 362 to 36 n of the insertion holes 34 for the bolts 32 (may be the number of connections of the lead wires 108 to be connected). Are inserted into the insertion hole 34 of the bolt 32, and the conductive wire 108a of the lead-in electric wire 108 with the outer cover peeled off is inserted, and the screwed nuts 362 to 36n are connected to the corresponding conductive wires 108a. By screwing and rotating in a direction approaching the wire 108a, the conductive wire 108a of the lead-in wire 108 is stabilized between the one surface side of each nut 362-36n and the concave inner surface 34a of the insertion hole 34 of the bolt 32. It is possible to make a pressure contact in the posture, and to ensure a conductive connection.

  In addition, the connecting portion 11 is inserted into the separate insertion hole 33 of the same bolt 12 with the conductive wire 107a of the pulling down electric wire 107 having the outer sheath peeled from the opening side of one end, After the parallel arrangement, the separate nut 361 is screwed into the bolt 32, whereby the conductive wire 107a of the pull-down electric wire 107 is placed between the nut 361 and the bottom surface 33a of the insertion hole 33 of the bolt 32. It is possible to press the conductive wire 107a of the pull-down electric wire 107 in a stable posture between the one surface side of the nut 361 and the concave bottom surface 33a of the insertion hole 33 of the bolt 32 so that the conductive connection is ensured. Can be made.

  As a result, the connecting portion 11 electrically connects the conductive wires 107a of the drawn-down electric wires 107 through the insertion holes 33 of the bolts 32, and electrically connects the conductive wires 108a of the separate drawn-in electric wires 108 through the insertion holes 34 at a plurality of locations. A plurality of lead-in wires 108 can be branched and connected to one place of the pull-down wire 107.

  Therefore, when it is necessary to increase the number of lead-in wires 108 to be connected to the pull-down wires 107, the wire connecting device 10 can insert the lead-in wires 108 into the insertion holes 34 that are already screwed or vacated by the nuts 36n that are appropriately added. By simply inserting the conductive wire 108a and press-connecting it, it is possible to branch-connect to the drawn-down electric wire 107, and it is possible to cope with it appropriately without adding another case 21.

  As described above, in the present embodiment, in addition to the operational effects of the first embodiment described above, the lead-in wire 108 that is more easily branched and connected to the pull-down wire 107 can be added.

  Here, as another aspect of the present embodiment, in this embodiment, the case where the insertion holes 33 and 34 are perforated and opened in a straight line on the straight bolt 32 will be described as an example, but the present invention is not limited thereto. For example, a bolt that bends between the insertion holes 33 and 34 may be used, and the opening direction of the insertion holes 33 and 34 may be arbitrarily set to form a compact structure. The extension direction of the lead-in wire 108 can be adjusted. Furthermore, the insertion hole 33 may be disposed between the insertion holes 34 so that the lead-in electric wires 108 are positioned on both sides of the pull-down electric wire 107.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.
