In addition, the pair of coated crimping pieces 34 b are caulked and fixed to the covering portion 16, and the electric wire 12 and the electric wire connecting member 30 are mechanically fixed.

  However, a pair of coated crimping pieces may be omitted, and only a pair of core wire crimping pieces may be crimped to the electric wire. In this case, the pair of core wire crimping pieces is a pair of wire crimping pieces. Also, a pair of core wire crimping pieces may be omitted, and the core wire may be connected to the bottom via a welded part or a soldering part by ultrasonic welding or the like, and only a pair of coated crimping pieces may be crimped to the covering part of the electric wire. is assumed. In this case, the pair of coated crimping pieces is a pair of wire crimping pieces. In addition, a configuration in which the electric wire connecting member does not have a pair of electric wire crimping pieces and the core wire is connected to the electric wire connecting member via a welded portion or a soldered portion by ultrasonic welding or the like is also assumed.

  A caulking piece 36 that can be caulked and fixed to the other of the mating side connection member 22 and the electric wire connection member 30 is formed on one side of the mating side connection member 22 and the electric wire connection member 30.

  In the present embodiment, a caulking piece 36 is formed on the wire connecting member 30. More specifically, a pair of caulking pieces 36 are provided so as to extend from both end portions of the bottom portion 32. The distance between the base ends of the pair of caulking pieces 36 is set to be the same as the distance between the pair of through holes 26h. Each of the pair of caulking pieces 36 is set to have a width dimension that can be inserted into the pair of through holes 26h. Further, the protruding dimension of the pair of caulking pieces 36 is set to a dimension exceeding the thickness dimension of the connecting piece 26. Then, with the pair of caulking pieces 36 inserted into the pair of through holes 26 h, the tip ends of the pair of caulking pieces 36 protrude to the lower surface side of the connecting piece 26. The bottom portion 32 and the pair of caulking pieces are formed by caulking and deforming a portion of the pair of caulking pieces 36 protruding below the connecting piece 26 so as to contact the lower surface side of the connecting piece 26 and caulking and fixing to the bottom portion 32. The connecting piece 26 is sandwiched between the distal end portion 36 and the wire connecting member 30 is caulked and fixed to the mating connection main body 24.

  The caulking pieces 36 are preferably provided at positions that can be caulked and deformed when caulking and fixing the pair of electric wire crimping pieces 34 to the electric wires 12. Here, the caulking pieces 36 are provided at both ends of the bottom portion 32 and at positions adjacent to the pair of wire crimping pieces 34. For this reason, as will be described later, when the pair of wire crimping pieces 34 is caulked and deformed, the caulking piece 36 can be easily deformed by using a crimping die for caulking and deforming them.

  Further, the caulking piece 36 is in a state in which the terminal 20 is viewed in a plan view (when the bottom portion 32 is viewed from the electric wire 12 side), and is disposed in a region overlapping with the pair of electric wire crimping pieces 34. It is fixed by caulking to the member 22. Here, the pair of caulking pieces 36 are caulked and deformed so as to fall down toward each other, and on the lower surface side of the connecting piece 26, one end portion of the pair of caulking pieces 36 is connected to the pair of core wire crimping pieces 34 a. It arrange | positions in the area | region which overlaps and the other front-end | tip part of a pair of caulking piece 36 is arrange | positioned in the area | region which overlaps with a pair of covering crimping | compression-bonding piece 34b. For this reason, the force for caulking and deforming the pair of core crimping pieces 34 a and the pair of covering crimping pieces 34 b is efficiently transmitted to the pair of caulking pieces 36 as the force for caulking and deforming the pair of caulking pieces 36. However, the pair of caulking pieces 36 may be deformed outward.

  A method for producing the terminal-attached electric wire 10 will be described.

  First, as shown in FIG. 4, a terminal 20 in which the mating connecting member 22 and the wire connecting member 30 are separated and an electric wire 12 in which the core wire 14 is exposed at the end are prepared.

  And as shown in FIG. 5, the edge part of the electric wire 12 is arrange | positioned on the bottom part 32 (process (a)). At this time, the exposed core wire 14 is disposed between the pair of core wire crimping pieces 34a, and the end portion of the covering portion 16 is disposed between the pair of covering crimping pieces 34b.

  In addition, the bottom portion 32 is overlaid on the connecting piece 26, and the pair of caulking pieces 36 are passed through the pair of through holes 26 h so that the tip ends of the pair of caulking pieces 36 protrude below the connecting piece 26.

  And as shown in FIG. 6, the connection piece 26, the electric wire connection member 30, and the edge part of the electric wire 12 are arrange | positioned on the lower metal mold | die 52 of the terminal crimping apparatus 50. As shown in FIG.

  Note that the overlapping of the connecting piece 26 and the bottom portion 32 may be performed before or after the end of the electric wire 12 is disposed on the bottom portion 32. Further, these steps may be performed on the lower mold 52 of the terminal crimping device 50.

  Next, the upper die 54 of the terminal crimping device 50 is moved toward the lower die 52. And when crimping | bonding a pair of electric wire crimping piece 34 to the electric wire 12, the caulking piece 36 is deformed and it crimps and fixes to the other party connection member 22. FIG.

  As the terminal crimping device 50 at this time, it is preferable to use the one having the following configuration. That is, the terminal crimping device 50 includes a lower mold 52 and an upper mold 54. The upward surface of the lower mold 52 has a lower mold surface 53 that supports the connecting piece 26 in a mounting shape from the lower side. Both ends of the lower mold surface 53 in the extending direction of the connecting piece 26 are formed as inclined surfaces 53f1 which are inclined upward toward the outside, and the intermediate portion of the lower mold surface 53 in the extending direction of the connecting piece 26 is formed. The portion is formed on an intermediate surface 53f2 extending along the extending direction of the connecting piece 26. The distance between the inclined surfaces 53f1 at both ends is set to be larger than the distance between the pair of caulking pieces 36, and the pair of caulking pieces 30 is disposed on the lower mold surface 53 with the wire connecting member 30 disposed on the lower mold surface 53. The piece 36 is configured to be able to contact the pair of inclined surfaces 53f1. The upper die 54 includes a core wire crimping upper die 54a for caulking and deforming a pair of core wire crimping pieces 34a, and a coating crimping upper die 54b for caulking and deforming a pair of coated crimping pieces 34b. The core wire crimping upper die 54a and the covering crimping upper die 54b are disposed above the intermediate surface 53f2 and are driven up and down by an actuator 58 such as an air cylinder or a hydraulic cylinder.

  Then, when the upper die 54 is moved downward with the connecting piece 26, the wire connecting member 30 and the ends of the wires 12 disposed on the lower die surface 53, as shown in FIG. The upper mold 54a contacts the upper portions of the pair of core wire crimping pieces 34a, and the pair of coated crimping pieces 34b are deformed inward. Further, the upper die 54b for covering and pressing comes into contact with the upper portions of the pair of covering and pressing pieces 34b, and deforms the pair of covering and pressing pieces 34b inward. Then, the electric wire connecting member 30 is pushed toward the lower mold surface 53. At this time, since the tip portions of the pair of caulking pieces 36 are pushed toward the pair of inclined surfaces 53f1, the pair of caulking pieces 36 are pushed toward each other according to the inclination of the pair of inclined surfaces 53f1. Turn inward.

  When the lower die surface 53 is further moved downward, as shown in FIG. 8, the upper die 54a for core wire crimping deforms the pair of core wire crimping pieces 34a further inwardly to be caulked and fixed to the core wire 14. In addition, the upper die 54 b for covering and crimping further deforms the pair of covering and crimping pieces 34 b inwardly and caulks and fixes them to the end portion of the covering portion 16. At this time, the pair of caulking pieces 36 are further bent inward and deformed so as to be in contact with the lower surface side of the connecting piece 26 by the intermediate surface 53f2. As a result, the pair of caulking pieces 36 are caulked and fixed to the bottom portion 32.

  According to the method of manufacturing the electric wire with terminal 10, the terminal 20, and the electric wire with terminal 10 configured as described above, the caulking piece 36 formed on one of the mating side connection member 22 and the electric wire connection member 30 By caulking and fixing to the other of the side connection member 22 and the wire connection member 30, the mating side connection member 22 and the wire connection member 30 can be easily combined.

  For example, the caulking deformation of the caulking piece 36 can be performed by sandwiching a pair of the lower die 52 and the upper die 54 as described in the above embodiment. Compared with the work of handling and uniting a plurality of members with fine work so that the hook part passes through the through hole and then the tip of the hook part is fitted into the first fitting recess, the work of joining is easier. is there.

  Further, since the caulking pieces 36 are provided at positions that can be caulked and deformed when caulking and fixing the pair of electric wire crimping pieces 34 to the electric wires 12, when caulking and deforming the pair of electric wire crimping pieces 34, It is also easy to deform the caulking piece 36 by using the force for caulking deformation.

  Specifically, as in the present embodiment, a pair of caulking pieces 36 are provided so as to extend from both end portions of the bottom portion 32, and a pair of through holes 26 h are formed in the connecting piece 26 of the mating connection member 22. When the pair of caulking pieces 36 are crimped and fixed by inserting the pair of caulking pieces 36 into the pair of through holes 26h in a state where the bottom portion 32 is overlapped with the connecting piece 26, In addition, the caulking piece 36 can be easily caulked and deformed.

  In addition, the caulking piece 36 is caulked and fixed to the connecting piece 26 of the mating connection member 22 in a state where the caulking piece 36 is disposed in a region overlapping with the pair of wire crimping pieces 34 in a state where the terminal 20 is viewed in plan. The force for caulking and fixing the pair of wire crimping pieces 34 to the end of the electric wire 12 can be more efficiently applied as the force for caulking and deforming the caulking piece 36. Here, the force that causes the pair of core wire crimping pieces 34a and the pair of coated crimping pieces 34b to be caulked and deformed at the ends of the electric wires 12 by moving the core wire crimping upper die 54a and the covering crimping upper die 54b downward, Below that, the pair of caulking pieces 36 can be effectively applied as a force for bending the caulking pieces 36 toward the lower surface of the connecting piece 26. For this reason, the other party connection member 22 and the electric wire connection member 30 can be united more reliably.

  In addition, since this terminal has a structure in which the mating connecting member and the wire connecting member are combined, a plurality of types of mating connecting members are prepared and a plurality of wire connecting members are prepared, and these are assembled appropriately. Various terminals can be manufactured by combining them together.

  For example, the mating connection member 22B shown in FIG. 9 is configured such that the coupling piece 26 is bent 90 degrees toward the locking piece 25 with respect to the mating connection main body 24. Further, the mating connection member 22C shown in FIG. 10 is configured such that the connecting piece 26 is bent obliquely toward the opposite side of the locking piece 25 with respect to the mating connection main body 24. As the counterpart connection member, in addition to the above, various configurations such as one in which the counterpart connection main body portion and the connecting piece are connected via a step, and one having no locking piece are assumed.

  Further, the wire connecting member 30B shown in FIG. 11 has a bottom 32B corresponding to the bottom 32 wider than the bottom 32, and a pair of core crimping pieces 34a and a pair of coated crimping pieces 34b on both sides thereof. It is set as the structure in which a pair of electric wire crimping piece 34 which has was formed. For this reason, the electric wire connecting member 30 </ b> B is suitable for connecting an electric wire having a diameter larger than that of the electric wire connecting member 30. In addition to the above, the wire connecting member is assumed to have various configurations such as those in which the distance between the core crimping piece and the coated crimping piece is different, and in which the plate thickness is different.

  The connecting pieces 26 of the mating connecting members 22B and 22C have the same configuration as the connecting piece 26 of the mating connecting member 22, and the positions, widths, etc. of the pair of caulking pieces 36 of the wire connecting member 30B are This is the same as the pair of caulking pieces 36 of the connecting member 30. For this reason, while selecting one of the plurality of mating connection members 22, 22B, 22C, selecting one of the plurality of wire connection members 30, 30B, and combining them, a plurality of types The terminal can be manufactured.

  In the above example, the three types of mating connection members 22, 22B, 22C and the two types of wire connecting members 30, 30B are used to pull out the electric wires 12 with respect to the mating connection main body 24, and to connect the wires suitable for a-attachment. Six types of terminals having different thicknesses can be manufactured. For this reason, it is possible to manufacture various terminals by reducing the types of metal plate press working used to manufacture each component.

{Modifications}
In the above embodiment, the example in which the caulking piece 36 formed on the electric wire connecting member 30 side is caulked and fixed to the mating connecting member 22 is described, but this is not necessarily required.

  A pair of through-holes 26h is omitted with respect to the connecting piece 126 (corresponding to the connecting piece 26) of the counterpart connecting member 122 (corresponding to the counterpart connecting member 22) as in the electric wire with terminal 110 shown in FIG. Instead, a pair of caulking pieces 136 may be formed on both sides. Further, the pair of caulking pieces 36 may be omitted in the electric wire connecting member 130 (corresponding to the electric wire connecting member 30). The pair of caulking pieces 136 are caulked and fixed to the outer periphery of the pair of core wire crimping pieces 34a crimped to the core wire 14 of the electric wire connection member 130, so that the mating connection member 122 and the electric wire connection member 130 are combined. ing.

  Thus, the caulking piece 136 formed on the mating connection member 122 may be caulked and fixed to the mating connection member 22. Also in this example, it is preferable that the caulking piece 136 is caulked and deformed when the pair of electric wire crimping pieces 34 are crimped to the electric wire.

  However, it is not essential that the caulking pieces 36 and 136 are caulked and deformed when the pair of electric wire crimping pieces 34 are crimped. The caulking pieces may be provided at positions apart from the pair of electric wire crimping pieces, and the caulking pieces may be deformed by caulking before or after the pair of electric wire crimping pieces are crimped to the electric wires.
