  Hereinafter, the terminal crimping apparatus according to the embodiment will be described.

  First, the terminal-attached electric wire to be processed will be described. FIG. 1 is a side view showing the terminal-attached electric wire 10.

  The electric wire with terminal 10 includes an electric wire 12 and a terminal 20.

  The electric wire 12 is configured such that the outer periphery of the core wire portion 13 is covered with a covering portion 14 by extrusion coating or the like. The core wire portion 13 is configured by a single wire or a stranded wire of metal wires such as copper, copper alloy, aluminum, and aluminum alloy. The covering portion 14 at the end of the electric wire 12 is peeled off, and an exposed core portion 13 a is formed at a part in the extending direction of the electric wire 12, here, at the end of the electric wire 12.

  The terminal 20 is formed by appropriately pressing a metal plate material such as copper or copper alloy. A plating layer of tin, nickel, or the like may be formed on the surface of the terminal 20.

  The terminal 20 includes a mating connection portion 22, a core wire crimping portion 24, and a covering crimping portion 26.

  The counterpart connection portion 22 is a portion connected to a counterpart terminal or the like, and is here formed in a substantially cylindrical shape, a so-called female terminal shape. Then, a mating terminal (so-called male terminal) having a pin-shaped or tab-shaped connecting section is inserted and connected to the mating connection section 22. However, the mating connection portion 22 may be formed in a pin-shaped or tab-shaped shape, a so-called male terminal shape, or in an annular shape that can be connected to the mating member by a screw or the like. It may be.

  The core wire crimping portion 24 is configured to be crimpable to the exposed core wire portion 13a. Here, the core wire crimping part 24 includes a bottom plate part 24a and a pair of core wire crimping pieces 24b rising from one side to the other side of the bottom plate part 24a. Then, in a state where the exposed core wire portion 13a is disposed on the bottom plate portion 24a, the pair of core wire crimping pieces 24b are bent inward so as to hold the exposed core wire portion 13a, thereby exposing the core wire crimping portion 24. Crimped to the core wire portion 13a.

  The covering crimping portion 26 includes a bottom plate portion 26a and a pair of covering crimping pieces 26b. Then, in a state where the end portion of the covering portion 14 is disposed on the bottom plate portion 26a, the pair of covering crimping pieces 26b are bent inward so as to hold the covering portion 14, so that the covering crimping portion 26 is formed. It is crimped to the end portion of the covering portion 14. The core wire crimping part 24 is provided continuously to one end part side of the covering crimping part 26 in such a manner that the bottom plate part 24a is continuously connected to one end part of the bottom plate part 26a.

  The terminal crimping device 30 will be described. FIG. 2 is a front view showing the terminal crimping device 30, and FIG. 3 is a side view showing the terminal crimping device 30.

  The terminal crimping device 30 is a device for crimping the core wire crimping part 24, the covering crimping part 26, and the end of the electric wire 12 of the terminal 20.

  The terminal crimping device 30 includes a first anvil 32, a second anvil 34, a first crimper 40, a second crimper 50, and a lift drive unit 60 that moves the first crimper 40 and the second crimper 50 up and down. .

  The 1st anvil 32 is comprised so that mounting | wearing with the crimping | compression-bonding part 26 is possible. More specifically, the first anvil 32 is formed in a shape that protrudes upward from the base portion 31 of the terminal crimping device 30. On the upper surface of the first anvil 32, a first lower pressure-bonding surface having a cross-sectional arc-like groove shape on which the covering pressure-bonding portion 26 can be placed is formed.

  The 2nd anvil 34 is comprised so that the core wire crimping part 24 can be mounted. More specifically, the second anvil 34 is formed in a shape that protrudes upward from the base 31 of the terminal crimping device 30 at a position adjacent to the first anvil 32. On the upper surface of the second anvil 34, a second lower pressure-bonding surface having a cross-sectional arc-shaped groove shape on which the bottom plate portion 24a of the core wire crimping portion 24 can be placed is formed.

  The first anvil 32 and the second anvil 34 are arranged so as to be arranged in a straight line according to the arrangement relationship between the covering crimping portion 26 and the core wire crimping portion 24. Then, with the covering crimping portion 26 and the core wire crimping portion 24 placed and supported on each of the first anvil 32 and the second anvil 34, the end of the covering portion 14 is crimped into the core crimping portion 26. The exposed core portion 13a can be disposed in the portion 24.

  The first anvil 32 and the second anvil 34 may have an integrated configuration or may be configured separately.

  The first crimper 40 is disposed at an upper position facing the first anvil 32. Further, the second crimper 50 is disposed at an upper position facing the second anvil 34 at a position adjacent to the first crimper 40.

  The raising / lowering drive part 60 is comprised by actuators, such as an air cylinder, a hydraulic cylinder, and a linear motor, and raises / lowers the said 1st crimper 40 and the 2nd crimper 50. As shown in FIG.

  4 is a schematic side view showing the positional relationship between the anvils 32 and 34 and the crimpers 40 and 50, the electric wire 12 and the terminal 20, and FIG. 5 is a schematic front view showing the positional relationship.

  As shown in the figure, the cover crimping portion 26 is placed on the first anvil 32, and the core wire crimping portion 24 is placed on the second anvil 34. The first crimper 40 and the first crimper 40 and the first crimper 40 are driven by the elevating drive unit 60 in a state where the end portion of the covering portion 14 is disposed in the covering crimp portion 26 and the exposed core portion 13a is disposed in the core wire crimping portion 24. When the two crimpers 50 are driven downward, the coated crimping portion 26 placed on the first anvil 32 is crimped to the end of the coated portion 14 of the electric wire 12, and the core wire crimped placed on the second anvil 34. The part 24 is crimped to the exposed core part 13 a of the electric wire 12.

  By the way, in order to perform the crimping | compression-bonding of the terminal 20 efficiently, as shown in FIG. 5, the some terminal 20 may be supplied to the terminal crimping | compression-bonding apparatus 30 with the form connected by the elongate strip-shaped connection band 28. FIG. In the present embodiment, a terminal feed mechanism 38 is provided on one side of the anvils 32, 34 to send the plurality of terminals 20 in the form of chained terminals toward the anvils 32, 34 (see FIG. 2).

  Although the terminal 20 sent in the form of a chain terminal is cut from the connection band 28 during crimping, one side of the terminal 20 to be crimped is in the middle of the lowering of the first crimper 40 and the second crimper 50. Next, the terminal 20 to be crimped is waiting. For this reason, a sufficient empty space may not be secured next to the terminal 20 to be crimped. The lateral space of the terminals 20 is limited by the distance S between the terminals 20 held in parallel by the connection band 28.

  On the other hand, a crimper for crimping, for example, the second crimper 50 is formed in an elongated plate shape, and an elongated concave second crimper side mold surface 52 is formed upward from the center of the lower part. The innermost (upper) portion of the second crimper side mold surface 52 is formed on a pressing surface 53 having a shape in which two arc-shaped peripheral surfaces that protrude upward are arranged side by side. The pressing surface 53 faces the second anvil 34. The distal side (lower side) side surfaces of the second crimper side mold surface 52 are formed as a pair of inwardly facing side surfaces 54 extending from the both sides of the pressing surface 53 toward the second anvil 34 below. Is formed. The pair of side surfaces 54 are formed in a shape that sequentially expands toward the distal end side. Then, when the core crimping part 24 is placed on the second anvil 34 and the exposed crimping part 13a is disposed therein, the second crimper 50 is moved toward the second anvil 34 to move the bottom plate part. In a state where 24 a is supported on the second anvil 34, the pair of core wire crimping pieces 24 b are curved and deformed inward along the second crimper side mold surface 52 while being in sliding contact with the second crimper side mold surface 52. To do. Thereby, a pair of core wire crimping piece 24b is crimped to the edge part of the exposed core wire part 13a.

  In the second crimper 50, the upper pressing surface 53 of the second crimper side mold surface 52 mainly exerts a compressive force for crimping the core wire crimping portion 24. The lower side surface 54 of the second crimper side mold surface 52 mainly plays a role of guiding the pair of pieces of the core wire crimping portion 24 inward.

  However, as described above, there may be a case where a sufficient empty space cannot be secured on the side of the terminal 20 to be crimped, as in the case of the terminal 20 sent in the form of a chain terminal. In such a case, it is difficult to form the outer portion 51 of the side surface 54 of the second crimper side mold surface 52 of the second crimper 50 to be wide, and it is necessary to form it narrowly. Then, the strength of the outer portion 51 is insufficient, and if the terminal 20 is repeatedly crimped, the outer portion 51 of the second crimper 50 may be frequently cracked.

  Therefore, in the present embodiment, the second crimper 50 is configured as follows. 6 is a front view showing the second crimper 50, FIG. 7 is a side view showing the second crimper 50, FIG. 8 is a partially enlarged view of FIG. 6, and FIG. 9 is a partially enlarged view of FIG. is there. In FIG. 9, the 2nd anvil 34, the electric wire 12, and the terminal 20 are also shown with the virtual line. FIG. 10 is a schematic cross-sectional view showing the relationship between the terminal 20 and the second crimper side mold surface 52 during crimping.

  As shown in these drawings, the second crimper 50 is formed to have a thickness larger than the dimension L in the extending direction of the core wire crimping portion 24 so as to protrude from the covering crimping portion 26 to the side where the electric wire 12 extends. Is provided.

  That is, when the terminal 20 and the electric wire 12 to be disposed on the anvils 32 and 34 are assumed, the dimension of the core wire crimping portion 24 is L in the extending direction of the terminal 20 and the electric wire 12. The thickness dimension D of the second crimper 50 in the same direction is larger than the dimension L. For this reason, the outer part 51 of a pair of side surface 54 among the 2nd crimpers 50 can be made comparatively thick in the said direction, and the strength improvement of the said outer part 51 can be aimed at.

  Further, the surface of the second crimper 50 opposite to the extending direction of the electric wire 12, that is, the surface of the terminal 20 on the side of the mating connection portion 22 is the edge of the mating connection portion 22 of the core crimping portion 24. Located at or near the location. Thereby, the part by the side of the other party connection part 22 among the core wire crimping parts 24 can be crimped more reliably. Moreover, the damage etc. with respect to the exposed core wire part 13a can be suppressed by preventing the 2nd crimper 50 from protruding from the core wire crimping part 24 to the other party connection part 22 side as much as possible. But the surface on the opposite side to the extending direction of the electric wire 12 among the 2nd crimpers 50 may protrude from the core wire crimping part 24 and the other party connection part 22 side.

  Moreover, the edge part by the side of the other party connection part 22 among the 2nd crimper side metal mold | die surfaces 52 may be formed in the shape which opens gradually toward the said other party connection part 22 side. Thereby, the edge part by the side of the other party connection part 22 among the core wire crimping parts 24 can be formed in the bell mouth shape which opens gradually toward the said other party connection part 22 side.

  In addition, the surface of the second crimper 50 on the extending direction side of the electric wire 12 protrudes outward (on the coated crimping portion 26 side) from the edge of the core crimping portion 24 on the direction in which the electric wire 12 extends.

  By causing the second crimper 50 to protrude to the side where the electric wire 12 extends, the second crimper 50 is connected to the counterpart connection portion 22 when the counterpart connection portion 22 is wider than the core crimping portion 24. Interference can be made difficult.

  The second crimper side mold surface 52 includes a tapered portion 52a that gradually widens toward the side where the electric wire 12 extends, at the opening edge on the side where the electric wire 12 extends. The tapered portion 52a is formed so as to incline in a uniform manner from the region where the core wire crimping portion 24 is crimped to the region where the electric wire 12 extends. Here, the tapered portion 52a is formed in a shape that gradually widens at the opening edge of the pressing surface 53 like the outer peripheral surface of the cone. Further, the tapered portions 52a are formed in the pair of outer portions 51 so as to spread outward with a certain inclination while forming a flat surface. For this reason, the tapered portion 52a can be easily formed by cutting or the like. That is, if the tapered portion 52a has a portion having a plurality of inclination angles, each inclination angle portion is manufactured by separate cutting or the like. In this embodiment, the tapered portion 52a is manufactured. Can be easily formed by cutting or the like because it has a uniformly inclined structure.

  The tapered portion 52a is formed so as to gradually open from a portion of the second crimper side mold surface 52 that contacts the edge of the core wire crimping portion 24 on the extension side of the electric wire 12. For this reason, when the 2nd crimper side metal mold | die surface 52 crimps | bonds the core wire crimping part 24, the taper-shaped part 52a contacts the edge part by the side of the extension of the electric wire 12 of the core wire crimping part 24. FIG. Thereby, the part 24p which makes the bell mouth shape which opens gradually toward the said extension direction is formed in the extension side part of the electric wire 12 among the core wire crimping | compression-bonding parts 24. As shown in FIG. The bell mouth-shaped portion 24p suppresses the edge portion of the core wire crimping portion 24 from being in strong local contact with the exposed core wire portion 13a.

  Further, the tapered portion 52a is further opened outward from a portion where the bell mouth-shaped portion 24p is to be formed. That is, the tapered portion 52 a is also formed at a position where the core wire crimping portion 24 is not pressed. For this reason, the second crimper side mold surface 52 of the second crimper 50 is less likely to hit the root portion of the exposed core wire portion 13a, the portion of the terminal 20 between the core wire crimp portion 24 and the cover crimp portion 26, and the like.

  According to the terminal crimping device 30 configured in this manner, the second crimper 50 is formed with a thickness larger than the dimension in the extending direction of the core crimping portion 24, and therefore the second crimper side mold surface 52 The thickness D of the outer portion 51 can be increased to suppress the cracking.

  Moreover, since the 2nd crimper 50 protrudes from the core wire crimping | crimped part 24 in the side which the electric wire 12 extends, it respond | corresponds easily when it is difficult to ensure the space which arrange | positions the 2nd crimper 50 on the opposite side. Can do. For example, this is effective when the mating side connection portion 22 is thicker than the core wire crimping portion 24 and the outer portion 51 of the second crimper 50 cannot be disposed on both sides of the mating side connection portion 22 or portions facing it.

  Further, a tapered portion 52 a that gradually spreads is formed at the opening edge portion of the second crimper 50 on the side of the second crimper side mold surface 52 that protrudes from the core crimping portion 24. For this reason, when crimping, the 2nd crimper 50 becomes difficult to interfere with the peripheral part of the core wire crimping part 24 among the electric wires 12, especially the base end part of the exposed core wire part 13a, etc.

  The relatively narrow portion of the tapered portion 52a serves to form the bell mouth shaped portion 24p in the core wire crimping portion 24, and the widened portion of the tapered portion 52a is the proximal end of the exposed core portion 13a. It plays a role of avoiding interference with other parts. In this way, by forming the tapered portion 52a having two functions so as to be inclined in a uniform manner, the tapered portion 52a can be easily formed continuously.

{Modification}
The above embodiment has been described on the assumption that the terminal crimping device 30 crimps the crimping terminal 20, particularly the core wire crimping portion 24, but the present invention can also be applied to the case where the covering crimping portion 26 is crimped. In addition, the present invention is applicable when crimping crimp parts of various crimp terminals. For example, the configuration related to the second crimper 50 of the terminal crimping device 30 is also suitable for crimping the inner conductor crimping portion 130 of the inner and outer conductor crimping terminal 120 to the electric wire 110 as shown in FIGS. 11 and 12. .

  That is, the electric wire 110 is the coaxial electric wire 110 here. The coaxial cable 110 includes a central conductor (inner conductor) 111, an insulating endothelial layer 112 formed of an insulating resin and covering the outer periphery of the central conductor 111, and a braided layer (outer peripheral side) covering the outer periphery of the insulating endothelial layer 112. (Conductor) 113 and an outer skin layer (covering portion) 114 formed of an insulating resin and covering the outer periphery of the braided layer 113.

  The central conductor 111, the insulating endothelial layer 112, and the braided layer 113 are sequentially exposed from the end of the coaxial cable 110.

  The inner and outer conductor crimp terminal 120 includes an outer conductor terminal 122, an inner conductor crimp portion 130 and a capacitor component 134 incorporated in the outer conductor terminal 122.

  The outer conductor terminal 122 is formed by appropriately punching and bending a metal plate, and the connecting portion 124, the terminal intermediate portion 126, the outer conductor crimping portion 128, and the covering crimping portion 129 are connected in a straight line. It has been configured.

  The connection part 124 is formed in a cylindrical shape. In the connection part 124, the counterpart connection part connected to the counterpart terminal and the capacitor component 134 are accommodated via an insulating member such as a resin. A lead 134a of the capacitor component 134 extends from the connection portion 124 toward the terminal intermediate portion 126 side.

  The outer conductor crimping portion 128 is a portion that is crimped to the braided layer 113 of the electric wire 110, and has a configuration in which a pair of crimping pieces 128b are provided on both sides of the bottom portion 128a.

  The covering crimping portion 129 is a portion to be crimped to the outer skin layer 114 of the electric wire 110, and has a configuration in which a pair of crimping pieces 129b are provided on both sides of the bottom portion 129a.

  The terminal intermediate portion 126 has a pair of side pieces 126a that connect the connecting portion 124 and the outer conductor crimping portion 128, and the inner conductor crimping portion 130 is used between the pair of side pieces 126a. A space for connecting the lead 134a and the center conductor 111 is formed. Further, the upper portion of the terminal intermediate portion 126 is opened, and the bottom portion thereof is opened through the crimping operation hole 135h. Then, the inner conductor crimping portion 130 is crimped through the upper opening of the terminal intermediate portion 126 and the crimping hole 135h.

  The inner conductor crimping portion 130 has a terminal structure in which crimping pieces 130b are provided on both sides of the bottom portion 130a, and is a portion to be crimped to the center conductor 111 and the lead 134a.

  When the inner conductor crimping portion 130 is crimped to the center conductor 111 and the lead 134a, the configuration related to the first crimper 40 can be employed. That is, the inner conductor crimping portion 130 is crimped to the center conductor 111 and the lead 134a in the terminal intermediate portion 126, but there are a pair of side pieces 126a on both sides of the crimping portion. For this reason, it is difficult to ensure a sufficient work space for performing crimping on both outer sides of the inner conductor crimping portion 130.

  Therefore, as the crimper for crimping the inner conductor crimping portion 130 in a state where the inner conductor crimping portion 130 is disposed in the second anvil 34 and the center conductor 111 and the lead 134a are disposed in the inner conductor crimping portion 130, The crimper 150 having the same configuration as the second crimper 50 can be used. Also in this case, the thickness dimension D of the crimper 150 is made larger than the dimension L in the extending direction of the inner conductor crimping section 130, and the crimper 150 is connected to the extension side of the coaxial cable 110, that is, the outer conductor crimping section. It arrange | positions so that it may protrude to 128 side. Thereby, the intensity | strength of the both sides of the crimper 150 can be enlarged, and the crack can be suppressed effectively. In addition, the opening edge of the crimper side mold surface 152 corresponding to the second crimper side mold surface 52 on the side where the central conductor 111 extends (the base end side of the central conductor 111) is the same extending side. It forms in the taper-shaped part 52a which spreads gradually toward. For this reason, even if the strand of the center conductor 111 spreads and spreads, the crimper side mold surface 152 hardly interferes with the center conductor 111.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
