JP 2007-26968 A

  When crimping and connecting the inner conductor of a coaxial cable and a capacitor lead using a co-crimp terminal, the upper die for crimping the co-crimp terminal passes through the lead placement hole formed in the middle part of the outer conductor terminal and enters the inner conductor terminal. It is arranged. For this reason, it is necessary to form the upper metal mold | die for crimping | compression-bonding terminal crimping below the width | variety which enters in the lead arrangement | positioning hole formed in the outer conductor terminal. Accordingly, the width of the upper mold has to be narrowed, and the upper mold is deformed by an open leg, which may cause a decrease in durability of the upper mold.

  Therefore, the present invention has an object to prevent deformation of the upper mold for crimping a crimp terminal when the crimp terminal is crimped using the crimping hole formed in the outer conductor terminal. To do.

  In order to solve the above problem, an electric wire having two conductors is crimped to a crimp terminal in which an inner conductor terminal and an electrical component are incorporated in an outer conductor terminal having a crimping portion and a co-crimping hole in the middle portion in the longitudinal direction. When connecting, the crimping portion is crimped to one of the two conductors, and the co-crimp terminal is connected to the other of the two conductors and the electric conductor at a position corresponding to the co-crimping hole in the outer conductor terminal. A terminal crimping apparatus according to a first aspect for crimping to a lead part of a component is disposed opposite to the first lower mold on which the crimping part can be placed, and the first lower mold. A first upper mold for crimping the crimping part placed on the one conductor to the one conductor, and a second capable of placing the co-crimp terminal in the outer conductor terminal through the co-crimping hole. A second lower mold having a lower mold surface is disposed opposite to the second lower mold, and the second lower mold surface is inserted therebetween. A pair of legs formed with a groove-shaped second upper mold surface that can be arranged, and the pair of legs are inserted into the co-crimping hole while the second upper mold surface is inserted into the second upper mold surface; By disposing the second lower mold surface, a second upper mold for crimping the co-crimp terminal placed on the second lower mold surface to the connection part of the electrical component and the other conductor; The second lower mold is provided on both outer sides in the width direction, and has a slidable contact surface that slidably contacts the outer surfaces of the pair of leg portions when the second lower mold and the second upper mold are relatively close to each other. A pair of guide portions.

  As in the terminal crimping device according to the second aspect, the sliding contact surfaces of the pair of guide portions may have a guide portion side guide portion that is inclined outward toward the second upper mold side.

  Like the terminal crimping apparatus according to the third aspect, the second upper mold has a leg-side guide portion that is inclined inwardly toward the second lower mold side on the outer side surface in the width direction of the pair of leg ends. You may have.

  As in the terminal crimping apparatus according to the fourth aspect, the second lower mold and the guide portion may be integrally formed.

  According to the terminal crimping apparatus according to the first aspect, when the second lower mold and the second upper mold relatively approach each other, the outer surfaces of the pair of leg portions of the second upper mold are slid on the pair of guide portions. Since the sliding contact is made with the contact surface, the pair of legs can be prevented from opening.

  Further, according to the terminal crimping apparatus according to the second aspect, when the second upper mold and the second lower mold are relatively close to each other, the pair of leg portions are smoothly paired with the guide portion side guide portion of the guide portion. It is guided between the guide portions and can be smoothly crimped.

The co-crimp terminal 38 is configured to be placed on the lower mold surface 70a.

  The guide portion 71 is integrally formed so as to be connected to both sides in the width direction of the protruding portion 70b of the second lower mold 70 via a lower base end portion of the protruding portion 70b. The guide part 71 is provided so that both the outer side surfaces in the width direction of the projecting part 70b and the sliding contact surfaces 71b on the inner side of the pair of guide parts 71 are spaced apart from each other. Here, the width direction is a direction connecting a pair of legs 91 described later. That is, this is a direction orthogonal to the crimping direction, which is the direction in which the second upper mold 90 moves closer to the second lower mold 70, and the axial direction of the coaxial cable 10. In the second lower mold, a concave groove portion 70 h is formed by the outer side surface in the width direction of the protruding portion 70 b and the sliding contact surface 71 b of the guide portion 71.

  The concave groove portion 70h has a width that allows a leg portion 91 of the second upper die 90 to be inserted when a second upper die 90 described later is brought close to the second lower die 70. Further, the sliding contact surface 71b of the guide portion 71 is formed so as to extend in a direction capable of sliding contact with the outer side surface in the width direction of the leg portion 91 when the second upper mold 90 is brought close to the second lower mold 70. Has been. That is, the interval between the two sliding contact surfaces 71 b formed on the inner side surfaces of the pair of guide portions 71 is substantially the same as the interval between the outer side surfaces of the pair of leg portions 91. The distance between the pair of sliding contact surfaces 71b and the distance between the outer surfaces of the pair of leg portions 91 are such that the pair of leg portions 91 can be disposed between the pair of sliding contact surfaces 71b and the pair of leg portions 91 are opened. What is necessary is just to be substantially the same as the leg can be prevented.

  Further, a guide portion side guide portion 71a that is inclined outward toward the second upper mold 90 side is formed at the tip portion of the sliding contact surface 71b. Here, the guide portion side guide portion 71a is formed such that the tip end portion of the sliding contact surface 71b opens outward in an arc shape.

  In addition, the protrusion dimension of a pair of guide part 71 is smaller than the protrusion dimension of the protrusion part 70b. Therefore, the guide portion 71 does not interfere with the outer conductor terminal 22 in a state where the tip end portion of the protruding portion 70 b is disposed in the outer conductor terminal 22.

  The second upper mold 90 has a pair of leg portions 91. The second upper mold 90 has a concave groove shape at a position on the inner side surface in the width direction of the pair of leg portions 91 and facing the second lower mold surface 70a. Two upper mold surfaces 90a are formed. More specifically, the inner surface in the width direction of the pair of leg portions 91 has an interval (here, the second lower mold) at which the protruding portion 70b including the second lower mold surface 70a can be inserted and arranged in the second upper mold surface 90a. 70 with a width slightly wider than the protruding portion 70b. The distance between both surfaces on the outer side in the width direction of the pair of leg portions 91 is formed in a width dimension that can be inserted into the co-crimping hole 35h of the outer conductor terminal 22 when the second upper mold 90 approaches the second lower mold 70. Has been. Two arcuate curved surfaces adjacent to each other are formed in the innermost (upper) portion of the second upper mold surface 90a. Furthermore, a leg side guide portion 91a that is inclined inward toward the second lower mold 70 is formed on the outer side surface in the width direction at the tip of the pair of leg portions 91.

  Then, in the terminal intermediate portion 26 of the outer conductor terminal 22, the second upper mold 90 is moved to the second lower mold 70 with the co-crimp terminal 38 placed on the second lower mold surface 70 a of the second lower mold 70. The co-crimp terminal 38 is crimped between the second lower mold surface 70a and the second upper mold surface 90a by being moved toward the second mold surface. At this time, the pair of leg portions 91 of the second upper mold 90 are disposed between the protruding portion 70b of the second lower mold 70 and the pair of guide portions 71 through the co-crimping hole 35h. The outer side surfaces of the pair are in sliding contact with the sliding contact surfaces 71 b of the pair of guide portions 71. Thereby, the opening leg of a pair of leg part 91 is suppressed.

  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.

  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.

  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 in which the center conductor positioning portion 68, the second lower mold 70, the second upper mold 90, and the lead positioning portion 92 are viewed from the coaxial cable 10 side along the axial direction of the outer conductor terminal 22. FIG. 10 is a view of the center conductor positioning portion 68 and the second lower mold 70 as viewed from above.

  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 inner portion (lower portion) of the slit portion 68a is positioned below the second lower mold surface 70a. 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 second upper mold 90 on the distal end side (inner conductor terminal side) of the outer conductor terminal 22. 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. In addition, 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 second upper mold surface 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 61, the first cut retainer portion 81, and the wire retainer portion 82 are viewed from the coaxial wire 10 side along the axial direction of the outer conductor terminal 22. It is a side view which shows the state immediately before separating the outer conductor terminal 22 from the chain strip 29a for outer 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 recessed 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 is outside the chain-like outer conductor terminal 29 fed through the outer conductor terminal feed guide hole 51. The conductor terminal chain 29a is introduced into the concave groove 61g.

  The outer conductor terminal cut portion 61 is connected to the outer conductor terminal 22 and the outer portion between the upper edge portion 61e of the opening of the concave groove portion 61g and the edge portion 64e of the first lower mold surface 64a on the first cut holding portion 81 side. In order to pass through the conductor terminal chain strip 29a in a manner that allows shearing, the conductor terminal chain strip 29a is disposed so as to be movable up and down at a position adjacent to the first lower mold 64.

  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 61b 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 the presser protrusion 81a of the first cut presser part 81 comes into contact with the upper surface of the first cut presser part 81, or before that, the upper end of the coaxial cable 10 on the wire guide groove 61b comes into contact. 10 is held at a fixed position on the wire guide groove 61b.

  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. As the ram member 48 is lowered, the second lower mold surface 70a is moved between the edge portion 70e on the concave groove portion 74g side and the edge portion 74e on the upper side of the opening portion of the concave groove portion 74g by the same configuration and operation as described above. Then, 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>
Operation | movement of the terminal crimping apparatus 40 comprised in this way is demonstrated. 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). At this time, when the ram member 48 is lowered, the co-crimp terminal 38 is separated from the co-crimp terminal chain band 39a and placed on the second lower mold surface 70a. When the ram member 48 is further lowered, the projecting portion 70b of the second lower mold 70 is disposed so as to project into the terminal intermediate portion 26 of the outer conductor terminal 22 through the co-crimping hole 35h. Thereby, the co-crimp terminal 38 is placed and supported on the second lower mold surface 70a at a position in the terminal intermediate portion 26 and corresponding to the co-crimp hole 35h.

  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 crimp portion 28 is crimped to the exposed braid layer 13 and the outer skin layer 14, and the second The upper die 90 approaches the second lower die 70, and the co-crimp terminal 38 is crimped to the center conductor 11 and the lead part 35 of the capacitor component 34.

  That is, in the state where 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, the second upper die 90 moves closer to the second lower die 70, and a pair of The co-crimp terminal 38 is crimped to the lead portion 34 and the center conductor 11 between the second upper mold surface 90a and the second lower mold surface 70a between the side pieces 26a.

  At this time, the leg portion 91 of the second upper mold 90 passes through the co-crimping hole 35h of the outer conductor terminal 22, and the protruding portion of the second lower mold 70 is formed by the leg side guide portion 91a and the guide portion side guide portion 71a. It is guided in the recessed groove portion 70 h formed by the sliding contact surface 71 b of 70 b and the guide portion 71. And the leg part 91 is inserted in the said recessed groove part 70h so that the width direction outer side surface of the leg part 91 may slidably contact with the sliding contact surface 71b of the guide part 71. FIG.

  Thereafter, the ram member 48 is raised by driving the elevating drive mechanism 49. At this time, if the crimping portion 28 or the co-crimping terminal 38 bites 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 the operation, the outer conductor terminal 22 is separated, the co-crimp terminal 38 is separated, and thereafter, the crimping of the crimp 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, when the co-crimp terminal 38 is crimped within the pair of side pieces 26 a of the outer conductor terminal 22, the widthwise outer surface of the leg portion 91 is slid on the guide portion 71. It is possible to prevent the leg portion 91 of the second upper mold 90 formed in a narrow width from coming into sliding contact with the contact surface 71b to be opened. Further, the leg portion 91 is guided into the concave groove portion 70h and can be smoothly inserted by the leg portion side guide portion 91a provided in the leg portion 91 and the guide portion side guide portion 71a provided in the guide portion 71. .
