  Next, the second lower mold 70 and the second upper mold 90 will be described. FIG. 8 is a diagram illustrating a state in which the second lower mold and the second upper mold are viewed from the coaxial cable side along the axial direction of the outer conductor terminal.

  The upper surface 70a of the second lower mold 70 is formed in a shallow groove shape that is curved in an arc shape, and the co-crimp terminal 38 can be placed on the upper surface 70a. A concave groove 90a is formed at a position below the second upper mold 90 and facing the upper surface 70a. Two arcuate curved surfaces are formed in the innermost (upper) portion of the concave groove 90a. The upper part of the second lower mold 70 and the lower part of the second upper mold 90 are each formed to have a width dimension that can be disposed between the pair of side pieces 26 a of the terminal intermediate part 26 of the outer conductor terminal 22. The co-crimp terminal 38 is placed on the upper surface 70 a of the second lower mold 70, and one lead portion 35 of the capacitor component 34 and the central conductor 11 of the coaxial cable 10 are disposed in the co-crimp terminal 38. In this state, the co-crimp terminal 38 is crimped to the lead part 35 and the center conductor 11 by bringing the second upper mold 90 close to the first lower mold 64.

  Here, in a plane that is substantially orthogonal to the direction in which the first upper mold 84 and the first lower mold 64 are relatively close to each other (that is, a substantially horizontal plane), between the first upper mold 84 and the first lower mold 64. When the crimping portion 28 is crimped, the second lower mold 70 and the second upper mold 90 are disposed at a position where the crimp terminal 20 can be crimped at a position where the crimp terminal 20 is disposed. Has been. In other words, in a substantially horizontal plane, the first upper mold 84 and the first mold 84 and the first crimping terminal 28 and the co-crimp terminal 38 can be crimped in a state where the crimp terminal 20 and the coaxial cable 10 are disposed at predetermined positions. A lower die 64, a second lower die 70, and a second upper die 90 are disposed.

  A removal stopper 79 is provided on the first upper mold 84 side of the second upper mold 90. The removal stopper 79 is formed in a substantially L-shaped plate shape. One end of the second upper mold 90 is disposed on the first upper mold 84 side of the vertical movement trajectory of the second upper mold 90 and in a posture substantially orthogonal to the outer conductor terminal 22, and the other end is disposed on the guide frame piece 46. It is supported on one side so as to be swingable through a shaft portion 79a. Further, the swinging range of the removal stopper 79 is regulated by bringing the other end into contact with the regulating member on the guide frame piece 46 side. The removal stopper 79 has a role of removing the crimping portion 28 biting into the first upper mold 84 and the co-crimping terminal 38 biting into the second upper mold 90. That is, when crimping is performed as described above, the crimp portion 28 may bite into the first upper mold 84 or the co-crimp terminal 38 may bite into the second upper mold 90. In this state, when the first upper mold 84 and the second upper mold 90 rise, the co-crimp terminal 38 and the outer conductor terminal 22 may rise together. In this case, the upper edges of the pair of side pieces 26a of the outer conductor terminal 22 come into contact with the other end of the removal stopper 79 while the co-crimp terminal 38 and the outer conductor terminal 22 are rising. The rise of the co-crimp terminal 38 is suppressed and the first upper die 84 and the second upper die 90 are removed. The regulation of the swing range of the removal stopper 79 is set to a range in which the rise of the outer conductor terminal 22 and the co-crimp terminal 38 can be suppressed while the first upper die 84 and the second upper die 90 are raised. Has been.

  Next, a configuration for guiding the center conductor 11 and the lead portion 35 of the capacitor component 34 will be described. FIG. 9 is a view showing a state where the central conductor positioning portion, the second lower mold, the second upper die, and the lead positioning portion are viewed from the coaxial cable side along the axial direction of the outer conductor terminal, and FIG. It is the figure which looked at the positioning part and the 2nd lower mold from the upper part.

  That is, the center conductor positioning portion 68 is provided at a position adjacent to the first lower mold 64 side than the second lower mold 70. A slit portion 68 a is formed at the front end portion of the center conductor positioning portion 68 along the vertical direction. The width dimension of the slit portion 68 a is set larger than the diameter dimension of the central conductor 11 and smaller than the inner width dimension of the co-crimp terminal 38. Further, the back portion (lower portion) of the slit portion 68 a is positioned below the upper surface 70 a of the second lower mold 70. Moreover, the upper side opening part of the slit part 68a is formed in the shape which expands sequentially toward an opening direction. Further, the width dimension of the center conductor positioning portion 68 is formed such that it can be disposed between the pair of side pieces 26 a of the terminal intermediate portion 26 of the outer conductor terminal 22. When the front end portion of the center conductor positioning portion 68 is inserted between the pair of side pieces 26a of the terminal intermediate portion 26 from below, it is adjacent to the co-crimp terminal 38 in the axial direction of the co-crimp terminal 38. At the position, the central conductor 11 is inserted into the slit portion 68 a and guided into the co-crimp terminal 38.

  The lead positioning portion 92 is provided at a position adjacent to the distal end side of the co-crimp terminal 38 from the second upper mold 90. A slit portion 92a is formed at the tip of the lead positioning portion 92 along the vertical direction. The width dimension of the slit portion 92 a is set to be larger than the diameter dimension of the lead portion 35 and smaller than the inner width dimension of the co-crimp terminal 38. Further, the back part (upper part) of the slit part 92 a is located at substantially the same position or slightly above the innermost part (upper part) of the concave groove 90 a of the second upper mold 90. In addition, the lower opening of the slit 92a is formed in a shape that sequentially expands in the opening direction. Furthermore, the width dimension of the lead positioning portion 92 is formed such that it can be disposed between the pair of side pieces 26 a of the terminal intermediate portion 26 of the outer conductor terminal 22. When the tip end portion of the lead positioning portion 92 is inserted between the pair of side pieces 26 a of the terminal intermediate portion 26 from above, the lead positioning portion 92 is positioned adjacent to the co-crimp terminal 38 in the axial direction of the co-crimp terminal 38. The lead part 35 is inserted into the slit part 92 a and guided into the co-crimp terminal 38.

  Next, a configuration in which the outer conductor terminal 22 is separated from the outer conductor terminal chain band 29a by the outer conductor terminal cut portion 61, the first cut holding portion 81, and the first lower mold 64 will be described.

  FIG. 11 is a view showing a state in which the outer conductor terminal cut portion, the first cut retainer portion, and the wire retainer portion are viewed from the coaxial wire side along the axial direction of the outer conductor terminal, and FIG. It is a side view which shows the state just before separating from the chain strip for conductor terminals.

  That is, the outer conductor terminal cut portion 61 is formed in a solid block shape, and a concave groove portion 61g capable of accommodating the outer conductor terminal chain band 29a in a portion adjacent to the first lower mold 64 inside thereof. Is formed. The concave groove portion 61g is formed along an extension line of the outer conductor terminal feed guide hole 51 of the terminal feed guide portion 50, and the outer conductor of the chain-like outer conductor terminal 29 fed through the outer conductor terminal feed guide hole. The terminal chain 29a is introduced into the concave groove 61g.

  The outer conductor terminal cut portion 61 is between the upper edge portion 61e of the opening of the concave groove portion 61g and the edge portion 64e of the upper surface 64a of the first lower mold 64 on the first cut holding portion 81 side. And the outer conductor terminal chain strip 29a are arranged so as to be movable up and down at positions adjacent to the first lower mold 64 so that they can be sheared in a manner capable of shearing.

  In addition, a substantially semi-cylindrical wire guide groove 61b is formed on the upper surface of the outer conductor terminal cut portion 61, and the coaxial cable 10 is placed on the wire guide groove 61b.

  The first cut presser 81 has a presser protrusion 81 a that protrudes downward through the side of the coaxial cable 10. The presser protrusion 81a is brought into contact with the side portion of the electric wire guide groove 81b on the upper surface of the first cut presser part 81 before the presser part 28 is pressed, and the first cut presser part 81 is lowered. It is formed with possible protruding dimensions.

  The wire retainer 82 is supported so as to be movable up and down with respect to the first cut retainer 81 and is biased downward by an elastic member 82S such as a coil spring. Then, when or before the presser protrusion 81a of the first cut presser 81 comes into contact with the upper surface of the first cut presser 81, it comes into contact with the upper part of the coaxial wire 10 on the wire guide groove 81b, and the coaxial wire 10 is held at a fixed position on the wire guide groove 81b.

  The first upper die 84 is disposed in a state where the outer conductor terminal chain band 29a is provided in the concave groove portion 61g and the crimping portion 28 of one outer conductor terminal 22 is provided above the first lower die 64. The ram member 48 is lowered to lower it. Then, the presser protrusion 81 a of the first cut presser part 81 comes into contact with the upper surface of the first cut presser part 81, and the first cut presser part 81 is lowered. That is, in response to the driving force of the elevating drive mechanism 49 that lowers the first upper mold 84, the first cut presser 81 is also lowered. Then, the portion between the outer conductor terminal 22 and the outer conductor terminal chain 29a is sandwiched between the upper edge portion 61e of the recessed groove portion 61g and the edge portion 64e of the first lower mold 64 (see FIG. 12). Eventually sheared and separated. The separated outer conductor terminal 22 is placed on the first lower mold 64, and then the first upper mold 84 is further lowered so that the crimping portion 28 is crimped on the first lower mold 64. Made.

  The recessed groove portion 61g of the outer conductor terminal cut portion 61 is located above the co-crimp terminal 38 placed on the second lower mold 70 in a state where the outer conductor terminal cut portion 61 is above. The outer conductor terminal 22 is arranged at an upper position than the co-crimp terminal 38. Accordingly, the outer conductor terminal 22 can be supplied onto the first lower mold 64 from the side while the co-crimp terminal 38 is supplied onto the second lower mold 70 from the side.

  Further, in a state where the outer conductor terminal cut portion 61 is lowered and the crimping portion 28 of the outer conductor terminal 22 is placed on the first lower mold 64, the outer conductor terminal 22 is lowered and placed on the second lower mold 70. The mounted co-crimp terminal 38 is disposed in the terminal intermediate portion 26 of the outer conductor terminal 22. In this state, the crimping portion 28 and the co-crimping terminal 38 can be crimped at substantially the same position and substantially simultaneously.

  In addition, the co-crimp terminal cut portion 74, the second cut retainer portion 94, and the second lower mold 70 separate the co-crimp terminal 38 from the co-crimp terminal chain 39a in the same manner as described above.

  That is, as shown in FIG. 6, the co-crimp terminal cut portion 74 is formed with a concave groove 74g in which the co-crimp terminal chain band 39a can be disposed. Moreover, the 2nd cut holding part 94 presses the co-crimp terminal cut part 74 below from the position which avoided the outer conductor terminal 22, and moves it. Then, by lowering the ram member 48, the same configuration and operation as described above, the edge portion 70e on the concave groove portion 74g side of the upper surface 70a of the second lower mold 70 and the edge portion 74e on the upper side of the opening portion of the concave groove portion 74g. In the meantime, the portion between the co-crimp terminal 38 and the co-crimp terminal chain band 39a is sheared to separate the co-crimp terminal 38 from the co-crimp terminal chain band 39a. The separated co-crimping terminal 38 is placed on the second lower die 70, and the second upper die 90 is subsequently lowered so that the co-crimping terminal 38 is crimped.

  The auxiliary support portion 76 is disposed below the connection portion 24 of the outer conductor terminal 22 and has a role of supporting the connection portion 24 from below. When the ram member 48 is lowered, the support presser 98 presses and moves the auxiliary supporter 76 downward at a position avoiding the connecting part 24 to the side. As a result, the support pressing portion 98 is lowered in synchronization with the outer conductor terminal cut portion 61 while supporting the connection portion 24 from below.

  At this time, the terminal pressing portion 96 presses the connection portion 24 from the upper portion thereof toward the auxiliary support portion 76 by the urging force of the urging member 96S. Thereby, the connection part 24 is firmly held on the auxiliary support part 76.

<4. Operation of crimp terminal>
The operation of the terminal crimping apparatus configured as described above will be described. First, in the initial state, the ram member 48 is in a raised state (see FIG. 6). In this state, due to the upward driving force of the ram member 48 just before, it passes through the outer conductor terminal feed guide hole 51 and the co-crimp terminal feed guide hole 52 of the terminal feed guide portion 50 and passes through the chain-like outer conductor terminal 29 and the chain-like joint. The crimp terminal 39 is sent. The outer conductor terminal 22 is disposed between the lower mold group 60 and the upper mold group 80 in a posture in which the crimping portion 28 is disposed above the first lower mold 64. The co-crimp terminal 38 is disposed on the second lower mold 70.

  The chain-like outer conductor terminal 29 and the chain-like co-crimp terminal 39 are wound around a reel and supplied from the reel. The inner conductor terminal 30 and the capacitor component 34 may or may not be incorporated in each outer conductor terminal 22 while being wound around the reel. In the latter case, the inner conductor terminal 30 and the capacitor component 34 may be assembled before the portion where the terminal crimping apparatus 40 performs terminal crimping.

  In this state, the operator arranges the end of the coaxial cable 10 between the lower mold group 60 and the upper mold group 80. At this time, the exposed central conductor 11 is arranged between the pair of side pieces 26 a, the exposed braided layer 13 is arranged between the crimping pieces 28 a of the crimping part 28, and the end of the outer skin layer 14 is arranged between the crimping pieces 28 b of the crimping part 28. To be installed.

  In this state, the ram member 48 is lowered by driving the elevating drive mechanism 49. Then, first, the outer conductor terminal cut portion 61 is lowered, and the outer conductor terminal 22 is separated from the outer conductor terminal chain band 29a and placed on the first lower mold 64 (see FIG. 12). Subsequently, when the ram member 48 is lowered, the co-crimp terminal 38 is separated from the co-crimp terminal chain 39 a and placed on the second lower mold 70.

  At this time, the center conductor 11 and the lead part 35 of the capacitor component 34 are guided by the center conductor positioning part 68 and the lead positioning part 92 so as to be within the co-crimp terminal 38. Further, the end portion of the coaxial cable 10 is held so as to be pressed by the wire pressing portion 82 on the outer conductor terminal cut portion 61. Further, the connecting portion 24 of the outer conductor terminal 22 is held so as to be pressed by the terminal pressing portion 96 on the auxiliary support portion 76.

  When the ram member 48 is further lowered, the first upper mold 84 is further brought closer to the first lower mold 64, and between them, the crimping portion 28 is crimped to the braided layer 13 and the outer skin layer 14, and co-crimping is performed. The terminal 38 is crimped to the center conductor 11 and the lead part 35 of the capacitor component 34.

  Thereafter, the ram member 48 is raised by driving the elevating drive mechanism 49. At this time, if the crimping portion 28 bites the co-crimp terminal 38 against the first upper die 84 or the second upper die 90, the outer conductor terminal 22 comes into contact with the removal stopper 79 in the middle of ascending, and the biting occurs. Removed.

  Further, the next outer conductor terminal 22 and the co-crimp terminal 38 are supplied between the lower mold group 60 and the upper mold group 80 in conjunction with the rise of the ram member 48.

  In the above description of operation, the outer conductor terminal 22 is cut off, the co-crimp terminal 38 is cut, and thereafter, the crimping of the crimping portion 28 and the co-crimp terminal 38 are performed almost simultaneously. Absent.

  The outer conductor terminal 22 may be separated from the co-crimp terminal 38 at substantially the same time. Alternatively, the outer conductor terminal 22 may be separated after the co-crimp terminal 38 is separated.

  Further, regarding the crimping of the crimping portion 28 and the crimping of the co-crimping terminal 38, either one may be performed first and the other may be performed later. These timings are set according to the protruding length of the first cut retainer 81 and the second cut retainer 94 from the ram member 48, the position where they contact the outer conductor terminal cut 61 and the co-crimp terminal cut 74, the first This can be done by appropriately adjusting the positions of the pressure bonding surfaces of the first lower mold 64, the second lower mold 70, the second lower mold 70, and the second upper mold 90.

  According to the terminal crimping device 40 configured as described above, the first lower mold in a plane (here, a substantially horizontal plane) substantially orthogonal to the direction in which the first lower mold 64 and the first upper mold 84 are relatively close to each other. When the crimping portion 28 is crimped to the braided layer 13 between the first upper die 84 and the first upper mold 84, the common crimping terminal 38 is connected to the central conductor 11 and the capacitor component at a position where the common crimping terminal 38 is disposed. The second lower mold 70 and the second upper mold 90 are disposed at positions where the lead portions 35 of the 34 can be crimped. Therefore, in the plane, the crimping portion 28 of the outer conductor terminal 22 and the crimping terminal 38 can be crimped with the co-crimping terminal 38 disposed at a fixed position. Are hardly misaligned with each other, and both can be bonded well.

  Note that the crimping position of the crimping portion 28 and the crimping position of the co-crimping terminal 38 do not have to coincide with each other in the vertical direction.

  In the present embodiment, the first lower mold 64 and the second lower mold 70 are fixed at fixed positions with respect to the base 42, and the first upper mold 84 and the second upper mold 90 are lowered downward. However, this is not always necessary, and even when both of them move, the first upper mold 84 and the second upper mold 90 are fixed, and the first lower mold 64 and the second lower mold 70 are raised. There may be. In short, it is sufficient if they are relatively close to each other.

  However, as in the present embodiment, the first lower mold 64 and the second lower mold 70 are fixed at a fixed position with respect to the base 42, and the first upper mold 84 and the second upper mold 90 are lowered downward. By doing so, it is possible to reduce the movable parts and the drive mechanism part, and to simplify the configuration. In addition, since the first lower mold 64 and the second lower mold 70 are fixed, the outer conductor terminal 22, the co-crimp terminal 38, and the coaxial cable 10 can be stably supported, and stable crimping can be performed.

  In the state where one outer conductor terminal 22 is disposed above the first upper mold 84 while the outer conductor terminal chain band 29a is disposed in the recessed groove portion 61g of the outer conductor terminal cut portion 61 moved upward, By receiving the driving force that lowers the first upper mold 84 toward the first lower mold 64 and lowering the outer conductor terminal cut portion 61, the outer conductor terminal 22 is connected to the outer conductor terminal chain 29a by the edge portions. And the crimping portion 28 is placed on the first lower mold 64. The crimping portion 28 of the outer conductor terminal 22 is crimped between the first lower mold 64 and the first upper mold 84. For this reason, after the outer conductor terminal 22 is separated, the crimping portion 28 can be continuously crimped, and these operations can be performed smoothly and quickly with a relatively simple configuration.

  In addition, in a state where the outer conductor terminal cut portion 61 is on the upper side, the outer conductor terminal 22 is disposed at a position higher than the co-crimp terminal 38 placed on the second lower mold 70. The terminal 38 can be easily disposed on the second lower mold 70 while avoiding interference with the outer conductor terminal 22. Then, the co-crimp terminal 38 placed on the second lower die 70 in a state where the outer conductor terminal cut portion 61 is lowered and the crimp portion 28 of the outer conductor terminal 22 is placed on the first lower die 64. Is disposed in the terminal intermediate portion 26 of the outer conductor terminal 22, so that both the crimping portion 28 and the co-crimping terminal 38 can be crimped almost simultaneously.

  Further, since the co-crimp terminal 38 is separated from the co-crimp terminal chain band 39a and the co-crimp terminal 38 is crimped in the same configuration, the detachment work and the crimp work are also relatively simple. Smooth and quick.

{Modifications}
In addition, the said raising / lowering drive mechanism part 49 may have two drive parts which raise / lower the said 1st upper type | mold 84 and the 2nd upper type | mold 90 separately, respectively.

  Further, as shown in FIG. 13, an opening 50h that exposes the outer conductor terminal feed guide hole 51 upward is formed on the upper surface of the terminal feed guide 50, and the capacitor component 34 and the inner conductor terminal 30 are connected thereto. You may provide the mechanism pushed into the front end side of the part 24. FIG. Such a mechanism, for example, supports the pushing tool 101 provided with a U-shaped groove 101g at the distal end thereof so as to be movable forward and backward along the axial direction of the outer conductor terminal 22 by a driving mechanism 104 such as an air cylinder. Further, it is possible to adopt a configuration in which the pushing tool 101 is arranged so as to be movable toward and away from the outer conductor terminal 22 in the outer conductor terminal feed guide hole 51 by a driving means (not shown).

  Then, in a state where the predetermined outer conductor terminal 22 is sent to a predetermined position in the outer conductor terminal feed guide hole 51, the pushing tool 101 is lowered, and the lead portion 35 of the capacitor component 34 is inserted into the groove. In this state, when the pushing tool 101 is retracted to a predetermined position, the capacitor component 34 and the inner conductor terminal 30 are surely pushed by the distal end side of the connecting portion 24.

  In addition, a detection unit that detects whether the capacitor part 34 is missing or is pushed to a predetermined position by image processing or the like may be provided in the opening 50h as described above.
