  In the terminal crimping apparatus shown in Patent Document 1 described above, an anvil and a crimper for crimping a terminal fitting on both of them are used to relatively position one terminal of the capacitor and the central conductor of the coaxial cable. Therefore, if one terminal of the capacitor and the central conductor of the coaxial cable are relatively displaced before crimping of the crimp terminal, the crimp terminal cannot be crimped in a normal state, There is a possibility that the electrical resistance value between the central conductor and the capacitor increases. In the worst case, the crimp terminal cannot be crimped to both the center conductor and the one terminal, and there is a possibility that a capacitor cannot be attached to the center conductor.

  Accordingly, an object of the present invention is to provide a terminal crimping apparatus capable of securely crimping a crimp terminal in a regular state on both a central conductor of an electric wire and a terminal of an electric component.

Further, the end of the coaxial cable 4 is accommodated in the positioning groove 45 of the positioning blade 37. Then, the crimp terminal 6, the one terminal 3 of the capacitor 2, and the central conductor 5 of the coaxial cable 4 overlap each other with a space therebetween.

  The drive source 15 is driven to lower the ram 22 and the crimper 21 via the shank 24 and the ram bolt 23. Then, the wire retainer 41 approaches the positioning blade 37, the crimper 21 approaches the anvil 20, and the second terminal mold 62 approaches the terminal guide 59. Then, as shown in FIGS. 17 and 18, the wire retainer 41 contacts the positioning blade 37, and the wire retainer 41 presses the positioning blade 37 against the biasing force of the coil spring 39, and the second terminal mold 62. Comes into contact with the terminal guide 59, and the second terminal mold 62 presses the terminal guide 59 against the urging force of the coil spring 61. At this time, of course, the coaxial cable 4, that is, the central conductor 5 is positioned by the wire retainer 41 and the positioning blade 37, and the capacitor 2, that is, one terminal 3 is positioned by the second terminal mold 62 and the terminal guide 59.

  Then, the positioning blade 37 and the terminal guide 59 are lowered, and as shown in FIG. 19, one terminal 3 overlaps the bottom plate portion 11, and the central conductor 5 overlaps the one terminal 3. Then, the anvil 20 bends the crimping piece 12 toward the bottom plate portion 11 and crimps the crimping piece 12. Further, when the wire presser 41 approaches the positioning blade 37, these disconnect the crimp terminal 6 from the chain 34. In this way, the terminal crimp terminal 6 cuts one crimp terminal 6 from the chain 13 and crimps the center conductor 5, the terminal 3 of the capacitor 2, and the crimp terminal 6. That is, they are pressed together.

  According to this embodiment, the crimping terminal 6 is provided with the conductor positioning part 26 for positioning the center conductor 5 and the terminal positioning part 27 for positioning the terminal 3 of the capacitor 2 when crimping the crimping terminal 6. When caulking, the conductor positioning portion 26 and the terminal positioning portion 27 can prevent relative displacement between the center conductor 5 of the coaxial cable 4 and the terminal 3 of the capacitor 2. The crimp terminal 6 can be securely crimped to both the central conductor 5 of the coaxial cable 4 and the terminal 3 of the capacitor 2 in a normal state.

  Both the positioning blade 37 and the wire retainer 41 are slidable in the contact / separation direction by the movement allowing portions 38 and 42, and both the positioning blade 37 and the wire retainer 41 are brought closer to each other by the biasing means by the coil springs 39 and 43. Is being energized. For this reason, when the positioning blade 37 and the wire presser 41 are crimped to the crimp terminal 6, even if the positioning blade 37 and the wire presser 41 are pressed in a direction approaching each other, they resist the urging force of the coil springs 39 and 43. Thus, the positioning blade 37 and the wire presser 41 can move. For this reason, the conductor positioning part 26 does not prevent the operation | work in which the anvil 20 and the crimper 21 crimp the crimp terminal 6. Therefore, the crimping terminal 6 can be caulked more reliably in a regular state on both the central conductor 5 of the coaxial cable 4 and the terminal 3 of the capacitor 2.

  The terminal guide 59 is slidable by the guide movement allowing portion 60, and the terminal guide 59 is urged toward the second terminal mold 62 by the coil spring 61. Therefore, even when the anvil 20 and the crimper 21 crimp the crimp terminal 6, even if the terminal guide 59 presses the second terminal mold 62, the terminal guide 59 resists the biasing force of the coil spring 61. Can move. For this reason, the terminal positioning part 27 does not prevent the operation | work in which the anvil 20 and the crimper 21 crimp the crimp terminal 6. Therefore, the crimping terminal 6 can be caulked more reliably in a regular state on both the central conductor 5 of the coaxial cable 4 and the terminal 3 of the capacitor 2.

  In the present embodiment, the central conductor of the coaxial cable 4 is shown. However, in the present invention, a core wire of a covered electric wire may be used as the central conductor. Furthermore, in the present invention, not only the capacitor 2 but also various electric parts may be used. Further, both the positioning blade 37 and the wire retainer 41 are slidably provided and are urged toward each other by the coil springs 39 and 43. In the present invention, only one of the positioning blade 37 and the wire retainer 41 is slid. It may be provided freely and biased by a coil spring. Further, in the present invention, the second terminal mold 62 may be slidable with respect to the ram 22, that is, the crimper 21.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
