In addition, after determining the entry direction corresponding to each and referring to the index indicating the arrangement order of the core wires corresponding to the entry direction, if the core wires are inserted into the guide holes, the arrangement is made in a predetermined arrangement order. There is no possibility of mistakes in the arrangement order, and it is possible to create modular plugs having different arrangement orders of the core wires by changing the incoming line direction.

Here, the index indicating the arrangement sequence of the core wires applied to the paired side surfaces is an index formed on one side surface, which is an index indicating the arrangement sequence of the core wires of the straight cable, and is formed on the other side surface. The index may be an index indicating the arrangement order of the core wires of the cross cable.
The guide plate may further be provided with an index indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire.

  As described above, according to the present invention, the guide plate for separating and straightening the core wire used for the modular plug is made point-symmetric with respect to the formation position of the plurality of guide holes and the shape of the side surface on which the guide holes are formed. Since the index indicating the arrangement order of the core wires is applied to each of the side surfaces forming a pair along the arrangement direction of the plurality of guide holes, the index is selected and the core wire is used as the guide hole while viewing the index. If inserted, it is possible to prevent misalignment of the core wires, and it is possible to create modular plugs with different core wire arrangement orders by changing the index to be referred to. It is possible to share the same guide plate when creating modular plugs for compatible cables.

It has eight guide holes 16 through which each core wire 7 is inserted. These guide holes 16 extend in parallel with each other, and are formed in two stages by arranging the adjacent guide holes shifted up and down alternately, and are aligned with the core wire insertion portion 8, that is, The core wire 7 inserted through the guide hole 16 is formed at a position where it is guided to the corresponding core wire insertion portion 8 as it is.

  The plurality of guide holes 16 formed in the guide plate 15 are formed in a point-symmetrical positional relationship (the positions at which the plurality of guide holes 16 are formed are set to be point-symmetric), and the guide holes 16 are formed. The shape of the side surface is also point-symmetric. Therefore, the guide plate 15 can be inserted into the housing 2 even when it is rotated upside down in a state of being opposed to each other, and the position of the guide hole 16 and the position of the core wire insertion portion 8 are aligned.

In this example, as shown in FIG. 2 (a), an index 20 indicating the arrangement order of the core wires for straight cables is applied to one side surface, and the other side surface is shown in FIG. 2 (b). Thus, the index 21 indicating the arrangement order of the core wires 7 for the cross cable is provided.

  Specifically, in order to create a modular plug of a straight cable, the arrangement order of the core wires 7 to be inserted through the guide holes 16 when the guide plates are arranged facing each other as shown in FIG. The index 20 is formed by arranging the corresponding colors of the core wires 7 in a band shape in the central portion of the side surface that is the upper surface of the guide plate 15 according to the arrangement order of the core wires 7 to be inserted into the guide holes 16. is doing. That is, the index 20 for creating the modular plug of the straight cable is “orange / white”, “orange”, “green / white”, “blue” on the side surface which is the upper surface of FIG. , “Blue / white”, “green”, “brown / white”, “brown” in order of the colored band (by coloring the band).

  Also, in order to create a modular plug of a cross cable, when the guide plate 15 is turned upside down and the incoming side of the core wire 7 is arranged facing the front as shown in FIG. A core wire to be inserted into the guide hole 16 at the center portion of the side surface (the side surface opposite to the side surface to which the index 20 indicating the arrangement order of the core wires for the straight cable is attached) that is the upper surface of the guide plate 15. In accordance with this order, the colors of the corresponding core wires are arranged in a band shape and arranged. That is, the index 21 for creating the modular plug of the cross cable is “green / white”, “green”, “orange / white”, “blue” on the side surface which is the upper surface of FIG. , “Blue / white”, “green”, “brown / white”, “brown” in order of the colored band (by coloring the band).

  Further, indicators 30 and 31 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wires are provided on the same side of the indicators 20 and 21 indicating the arrangement order of the core wires 7. Specifically, when the guide plate 15 is used as a straight cable and arranged as shown in FIG. 2A, the index 30 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire is the core wire. The upper surface in the figure shows an arrow indicating that the wire 7 is inserted from the front surface to the back surface, and a letter “S”, for example, indicating that the insertion in the direction of the arrow is the insertion of the core wire 7 for creating a straight cable. It is formed by providing it next to the indicator 20 indicating the arrangement order of the core wires 7 attached to the. When the guide plate 15 is arranged as shown in FIG. 2B for use as a cross cable, the index 31 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire is the front of the core wire 7. An arrow indicating the insertion from the back to the back, and a letter “X”, for example, indicating that the insertion in the direction of the arrow is the insertion of a core wire for creating a cross cable is attached to the upper surface in the figure. It is formed by providing it next to the indicator 21 indicating the arrangement order of the core wires.

  The indicators 30 and 31 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire may be retrofitted by a seal or engraving or formed integrally when the guide plate is formed. Good.

  In the above configuration, to create a modular plug for a straight cable, as shown in FIG. 2 (a), a guide plate 15 is arranged with the side surface with the letter “S” attached, and the modular cable is arranged. 3. Untwist the tip of each core wire 7 and turn the tip of each core wire 7 in the order of the color of the indicator and the color of the core wire while looking at the indicator 20 indicating the arrangement order of the core wires for straight cables of the guide plate 15 Each core wire 7 is inserted through the corresponding guide hole 16 in the direction of the arrow so as to match (FIG. 3A).

  Then, while maintaining this state, each core wire 7 is inserted into the cable insertion portion 6 from the cable insertion port 4 of the housing 2 together with the guide plate 15 (FIG. 4A). When the guide plate 15 inserted together with the core wire 7 comes into contact with the portion that transitions from the cable insertion portion 6 to the core wire insertion portion 8, it is not inserted any further and is held at that location (FIG. 4 ( b)). Thereafter, when the modular cable 3 is further inserted, the protruding amount of the core wire 7 from the guide plate 15 increases, and only the core wire 7 is pushed into the corresponding core wire insertion portion 8, and the tip of the core wire 7 is inserted into the core wire. The end of section 8 is reached (FIG. 4c). Thereby, the covering portion 5 of the modular cable 3 is disposed in the cable insertion portion 6, and the distal end portion of each core wire that is inserted through the guide plate 15 is disposed in the core wire insertion portion 8. Thereafter, the blade terminal 10 held by the terminal holding portion 11 is inserted into each core wire 7 positioned in the core wire insertion portion 8 of the housing 2 by press-fitting using a press-fit tool, and the corresponding core wire 7 and the blade terminal are inserted. 10 is electrically connected, the production of the modular plug for the straight cable is completed.

  On the other hand, to create a modular plug for a cross cable, the guide plate 15 is turned upside down and arranged as shown in FIG. 2 (b), and the end of each core wire 7 of the modular cable 3 is twisted. After unraveling, the guide hole 16 corresponding to the order of the color of the index and the color of the core wire 7 while looking at the index 21 indicating the arrangement order of the crossing cables for the crossing cable of the guide plate 15 at the tip of each core wire 7. Is inserted in the direction of the arrow (FIG. 3B).

  Thereafter, through the same process as shown in FIG. 4, the covering portion 5 of the modular cable 3 is arranged in the cable insertion portion 6, and the distal end portion of each core wire 7 inserted through the guide plate 15 is arranged in the core wire insertion portion 8. The blade terminal 10 held by the terminal holding portion 11 is press-fitted into each core wire 7 positioned in the core wire insertion portion 8 of the housing 2 using a press-fit tool, and the corresponding core wire 7 and the blade terminal 10 are electrically connected. Once connected, the production of the modular plug for the cross cable is complete.

  Therefore, according to the above-described configuration, in the guide plate 15 for separating and straightening the core wires 7 used in the modular plug 1, the formation positions of the plurality of guide holes 16 and the shape of the side surface on which the guide holes 16 are formed are the same. Indexes 20 and 21 indicating different arrangement orders of the core wires are provided on each of the paired side surfaces along the arrangement direction of the guide holes 16 so as to be point-symmetric. If the core wire 7 is inserted into the guide hole 16 while looking at the index above, the alignment order is selected. For this reason, there is no possibility of mistakes in the arrangement order, and modular plugs (modular plug for cross cable and modular plug for straight cable) having different arrangement orders of the core wires 7 can be created by changing the index to be referred to. Thus, the same guide plate 15 can be shared when manufacturing modular plugs having different arrangement orders of the core wires 7.

  Further, since the indicators 30 and 31 indicating the type of cable and the insertion direction of the core wire are further provided beside the indicators 20 and 21 indicating the arrangement order of the guide plates 15, the arrangement of the core wires according to the type of the cable to be created. The indexes 20 and 21 indicating the order can be easily selected, and there is no possibility of erroneous insertion direction of the core wires 7 corresponding to the array order index.

  In the above-described configuration, the indices 20 and 21 indicating the arrangement order of the core wires 7 are collectively provided near the center. However, the core wires 7 to be inserted at positions directly above the respective guide holes 16 and By attaching colored bands of the same color, a wide range of indicators of the arrangement order is formed, and a cable corresponding to the arrangement order is provided on the side surface (side surface in the vertical direction in the figure) along the direction orthogonal to the arrangement direction of the guide holes 16. Indicators 30 and 31 indicating the type of the wire and the insertion direction of the core wire may be provided.

  Moreover, in the above-mentioned structure, it can be used to create modular plugs of different types of cables by using the guide plate 15 upside down with the same direction of insertion of the core wire 7 into the guide plate 15. However, the guide plate 15 may be made to correspond to different types of cables by changing the direction of entry of the guide plate 15 (inverting the guide plate 15 back and forth).

  A configuration example of such a guide plate 15 is shown in FIG. 5, and this configuration example will be described below with a focus on differences from the configuration example. The guide plate 15 shown in FIG. 5 is formed in, for example, a rectangular parallelepiped shape symmetrical to the left, right, front, back, and top and bottom, and has eight guide holes for separately separating and aligning and holding the core wires 7 forming four pairs. However, the guide holes 16 are parallel to each other in that they are formed in two stages by shifting the guide holes 16 up and down alternately. The upper guide hole and the lower guide hole are extended obliquely from the front side to the back side, and the direction in which the guide holes 16 are arranged side by side and perpendicular to the drilling direction (vertical direction in the figure). Are projected in different directions so as to cross at a predetermined angle.

  Each guide hole 16 is formed in a positional relationship in which the core wire 7 inserted therethrough is guided to the core wire insertion portion 8 as it is, and is formed symmetrically with respect to the longitudinal axis (A) of the guide plate 15. Has been. Therefore, even if the guide plate 15 shown in FIG. 5A is rotated by 180 degrees with respect to the axis (A) as shown in FIG. 5B, the relative position between the guide hole 16 and the core wire insertion portion 8 is increased. Is the same as FIG. 5 (a).

  Different indicators 20 and 21 indicating the arrangement order of the core wires 7 are provided on side surfaces (upper surface and lower surface in the figure) that form a pair along the arrangement direction of the plurality of guide holes 16. In this example, the color of the core wire 7 to be inserted along the direction in which each guide hole is drilled is provided in a strip shape, and the index of the upper guide hole and the index of the lower guide hole cross each other. In addition, when the projection is projected in a direction (vertical direction in the figure) perpendicular to the direction in which the guide holes 16 are juxtaposed and the direction in which the guide holes 16 are drilled, It is applied so as to overlap with the corresponding guide hole.

  Particularly in this example, as shown in FIG. 5 (a), an index 20 indicating the arrangement order of the core wires for straight cables is provided on one side surface, and the other side surface is shown in FIG. 5 (b). As shown, an index 21 indicating the arrangement order of the core wires 7 for the cross cable is provided.

  Specifically, in order to create a modular plug of a straight cable, when the guide plate 15 is arranged facing the front as shown in FIG. 5A, the arrangement order of the cores 7 inserted through the guide hole 16 is changed. The guide 20 corresponding to the colored band of each core wire 7 to be inserted into each guide hole 16 in accordance with the arrangement order of the core wires 7 to be inserted into the guide holes 16 on the side surface which is the upper surface of the guide plate 15. It is formed by being attached in parallel above the hole 16. In other words, the index 20 for creating a modular plug of a straight cable is a colored band of “orange / white” and “orange” attached to the side surface which is the upper surface of FIG. "Green / white" and "blue" colored bands attached to the shape, "blue / white" and "green" colored bands attached to the cloth, "brown / white" and "tea" attached to the cloth It is formed by sequentially arranging colored bands.

  Further, in order to create a modular plug of a cross cable, the arrangement order of the core wires 7 when the guide plate 15 is reversed in the front-rear direction and the incoming line side of the core wire 7 is opposed to each other as shown in FIG. The order of the core wire 7 to be inserted into the guide hole 16 on the side surface (the side surface opposite to the side surface with the index 20 indicating the arrangement order of the core wires for straight cables) on the upper surface of the guide plate 15 The colored band of the color of the core wire 7 to be inserted into each guide hole 16 is attached to the upper side of the corresponding guide hole 16 in parallel. That is, the index 21 for creating the modular plug of the cross cable is the “green / white” and “green” colored bands, crossed from the right side of the incoming line on the side surface that is the upper surface of FIG. "Orange / white" and "blue" colored bands attached to the shape, "blue / white" and "orange" colored bands attached to the cross, "brown / white" and "tea" attached to the cloth It is formed by sequentially arranging colored bands.

  Further, on the side surface of the guide plate 15 with the indicators 20 and 21 and the side surface orthogonal to the side surface where the guide hole 16 opens (the side surface along the left and right vertical directions in the figure), the cable corresponding to the arrangement order is arranged. Indices 30 and 31 indicating the type and the insertion direction of the core wire are provided. Specifically, in the case of use for a straight cable, an arrow that allows the core wire 7 to be inserted from the front side to the back side when the incoming side of the core wire 7 is arranged facing the front as shown in FIG. Then, an index indicating that the insertion in the arrow direction is the insertion of a core wire for creating a straight cable, for example, the letter “S” is applied to one side surface of the guide plate 15 along the left and right vertical directions. Further, in the case of use for a cross cable, in the case where the incoming side of the core wire 7 is arranged facing the front as shown in FIG. 5B, an arrow that allows the core wire 7 to be inserted from the front to the back, and An index indicating that the insertion in the direction of the arrow is the insertion of a core wire for creating a straight cable, for example, the letter “X” is the other side surface of the guide plate 15 along the left and right vertical directions (cable for straight cable And the side surface opposite to the side surface to which the index 30 indicating the insertion direction of the core wire is attached.

  The indexes 30 and 31 indicating the type of cable and the insertion direction of the core wire corresponding to the arrangement order also function as an index indicating the vertical relationship when the guide plate 15 is arranged as shown in FIG. That is, by adding an arrow indicating the insertion direction of the core wire 7 above the index indicating the type of cable, the guide plate 15 is arranged above and below the index indicating the type of cable as shown in FIG. In this case, the vertical relationship of the guide plate 15 can be recognized. It should be noted that the indicators 30 and 31 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire are integrally formed when the guide plate is molded, even if it is retrofitted with a seal or engraving. May be.

  In the above configuration, in order to create a modular plug for a straight cable, a guide plate 15 is arranged as shown in FIG. 5A to untwist the tip of each core wire 7 of the twisted pair wire of the modular cable. The front end of each core wire 7 is viewed in front of the corresponding guide hole 16 so that the color of the index matches the color of the core wire 7 while looking at the index 20 indicating the arrangement order of the core wires of the guide plate 15. (Fig. 6 (a)).

  Then, while maintaining this state, each core wire 7 is inserted into the cable insertion portion 6 from the cable insertion port 4 of the housing 2 together with the guide plate 15 (FIG. 4A). When the guide plate 15 inserted together with the core wire 7 comes into contact with the portion that transitions from the cable insertion portion 6 to the core wire insertion portion 8, the guide plate 15 is no longer inserted deeper and the portion is held (FIG. 4 ( b)). Thereafter, when the modular cable 3 is further inserted, the protruding amount of the core wire 7 from the guide hole 16 increases, and only the core wire 7 is pushed into the corresponding core wire insertion portion 8, and the tip of the core wire 7 is inserted into the core wire. The terminal 8 is reached (FIG. 4C). Thereby, the covering portion 5 of the modular cable 3 is disposed in the cable insertion portion 6, and the distal end portion of each core wire 7 inserted through the guide plate 15 is disposed in the core wire insertion portion 8. Thereafter, the blade terminal 10 held by the terminal holding portion 11 is inserted into each core wire 7 positioned in the core wire insertion portion 8 of the housing 2 by press-fitting using a press-fit tool, and the corresponding core wire 7 and the blade terminal are inserted. 10 is electrically connected, the production of the modular plug for the straight cable is completed.

  On the other hand, in order to create a modular plug for a cross cable, the guide plate 15 is rotated 180 degrees with respect to the longitudinal axis to invert the front and back, and is arranged as shown in FIG. . Then, after untwisting the tip end of each core wire 7 of the twisted pair wire of the modular cable 3, while looking at the index indicating the arrangement order of the core wires of the guide plate 1 at the tip end of each core wire 7, the color of the index and the core wire 7 Each core wire 7 is inserted through the corresponding guide hole 16 from the front so as to match the color (FIG. 6B). Thereafter, through the same process as shown in FIG. 4, the covering portion 5 of the modular cable 3 is arranged in the cable insertion portion 6, and the distal end portion of each core wire 7 inserted through the guide plate 15 is arranged in the core wire insertion portion 8. The blade terminal 10 held by the terminal holding portion 11 is press-fitted into each core wire 7 positioned in the core wire insertion portion 8 of the housing 2 using a press-fit tool, and the corresponding core wire 7 and the blade terminal 10 are electrically connected. Once connected, the production of the modular plug for the cross cable is complete.

  Therefore, according to the above-described configuration, the guide plate 15 for separating and straightening the core wires 7 used in the modular plug can be reversed in the direction of entry into the guide holes 16 and the guide holes 16 are arranged in the arrangement direction. Since the indicators 20 and 21 indicating the arrangement order of the core wires corresponding to the respective incoming line directions are attached to the side surfaces forming a pair along the line, there is no possibility that the arrangement order is wrong, and the incoming line direction to the guide plate 15 is determined. It becomes possible to create modular plugs (modular plug for cross cable and modular plug for straight cable) by changing the arrangement order of core wires 7, and the same when manufacturing modular plugs with different arrangement order of core wires 7 The guide plate 15 can be shared.

  In addition, since the guide plate 15 is further provided with indexes 30 and 31 indicating the type of cable corresponding to the arrangement order and the insertion direction of the core wire, the index 20 indicating the arrangement order of the core wires according to the type of cable to be created. , 21 can be easily selected, and there is no risk of erroneous insertion of the core wires corresponding to the array order index.

  In the above-described configuration, an example in which the indicators 20 and 21 indicating the arrangement order of the core wires 7 are provided on the side surfaces (the upper surface and the lower surface in the drawing) along the arrangement direction of the guide holes 16 has been described. Instead, the index may be configured by attaching the color of the core wire to be inserted to the incoming line side periphery of each guide hole 16.
