     This application is a division of U.S. patent application Ser. No. 11/712,421, filed Mar. 1, 2007, which application claims priority of Japanese Patent Application No. 2006-106027, filed Apr. 7, 2006, the entire contents of which are incorporated herein by reference. 
    
    
     FIELD OF INVENTION 
     The present invention relates to a terminal crimping apparatus and a method for crimping a terminal, which crimps an electric wire to a terminal having crimping pieces, the ends of which are curved in the direction of approaching each other. 
     RELATED ARTS 
     When constructing a wiring harness, in which a terminal is electrically connected to an electric wire, i.e., by crimping the crimping piece of the terminal to the electric wire, various crimping apparatus is used (as an example, refer Patent Document 1). The terminal crimping apparatus has an anvil, a crimper, and a driving unit. The anvil and the crimper are arranged movably in the direction of approaching and parting each other to crimp an end of the electric wire to the crimping piece of the terminal by inserting the end of the electric wire in between the crimping pieces. The driving unit moves the anvil and the crimper in the direction of approaching and parting each other. 
     In the mentioned terminal crimping apparatus referred in Patent Document 1, a braid of a shielded wire in which the inner terminal is previously crimped to the core is crimped to an outer terminal, which is electrically isolated from the inner terminal while containing the same. The outer terminal has a bottom plate for positioning the braid of the shielded wire on the surface of the bottom plate and a pair of crimping pieces extending from outer edges of the bottom plate. By inserting the braid of the wire between the crimping pieces and then, bending the crimping pieces towards the bottom plate the outer terminal is electrically connected with the braid. The crimping piece of the outer terminal is more tightly contacted with the braid of a shielded wire by crimping, since each end of the crimping pieces parted from the bottom plate are previously curved in the direction of approaching each other. 
     In the mentioned terminal crimping apparatus referred in Patent Document 1, after the inner terminal is inserted into the outer terminal, the braid of a shielded terminal connected with the inner terminal is inserted in between the crimping pieces and the inner terminal is inserted in between the outer terminal while the crimping pieces are bent by moving the anvil towards the crimper close to each other. The terminal crimping apparatus shown in Patent Document 1 assembles the terminal of a coaxial cable by assembling the outer terminal and the inner terminal and connecting the shielded wire to the outer terminal. 
     Patent Document 1 is JP 3456422. 
     SUMMARY OF THE INVENTION 
     In a terminal crimping apparatus by prior art as referred in Patent Document 1, since the crimping piece has a curved end there was a possibility of a problem that the braid wire is interfered with the end of the crimping piece when inserting the braid wire of the shield wire between the crimping pieces. When the braid is interfered with the end of the crimping piece, the crimping piece shall be crimped while the braid is not thoroughly inserted in between the crimping pieces. Thereby, was a possibility that the braid and the crimping pieces, that is, the outer terminal are not sufficiently connected with each other. Therefore, by using the crimping apparatus mentioned in Patent Document 1, there was a possibility that the braid (i.e., the shielded wire) is not securely crimped to the terminal. 
     An object of the present invention is to provide a reliable terminal crimping apparatus and a terminal crimping method, which crimps an electric wire to a terminal having crimping pieces, ends of which curve in a direction of approaching each other. 
     In order to attain the mentioned object, a terminal crimping apparatus according to the present invention, for connecting an electric wire and a terminal, in which a pair of crimping pieces extending vertically from a bottom plate is formed at each end farther from the bottom plate with a curved portion curved to approach each other to crimp the terminal by bending the crimp pieces so as to make the ends thereof close to the bottom plate, includes a first die for placing the terminal on a surface thereof, a second die arranged correspondingly to the first die and freely approaching and parting the first die to crimp the crimp pieces by approaching the first die, and a third die arranged correspondingly to the first die and freely approaching and leaving from the first die to approach the first die before the second die crimps the crimping piece so as to push the electric wire toward the bottom plate and insert the electric wire between the pair of crimp pieces. 
     A terminal crimping apparatus mentioned above is further characterized in that the third die is arranged slidably in a direction of which the first die and the second die approach and part with each other and is urged towards the first die by an urging device, further projecting towards the first die than the second die when the third die is separated from the first part. 
     A terminal crimping apparatus mentioned above further including a driving unit for moving the third and the second dies to approach and part together from the first die, and the driving unit is a servomotor. 
     In a terminal crimping apparatus mentioned above, the first die and the second die are arranged slidably in the direction of approaching and parting each other. A positioning jig is provided to urge towards the first die by an urging device and position the terminal by approaching towards the first die and clamping the terminal between the first die and itself before the third die inserts the electric wire in between the crimping pieces. 
     In a terminal crimping apparatus mentioned above includes a detecting device in which detects whether or not the third parts has inserted the electric wire in between the pair of crimping pieces. 
     A terminal crimping apparatus mentioned above includes a pressure-contact member, which connects the electric wire to a pressure-contact portion provided at the terminal by pressing the electric wire towards the pressure-contact portion. 
     In a terminal crimping method according to the present invention, a pair of a crimping pieces extends vertically from a bottom plate of a terminal which is curved in a direction of approaching each other at an end thereof farther from the bottom plate is bent towards the bottom plate of the terminal to crimp the electric wire to the crimping pieces. The method includes the steps of positioning the terminal on a surface of a first die, inserting the electric wire in between the pair of crimping pieces, moving the first die and a second die towards each other, and crimping the electric wire with the crimping pieces. 
     In the terminal crimping apparatus according to the present invention, the electric wire is securely inserted in between the curved crimping pieces by having a third die which inserts the electric wire in between the pair of crimping pieces-by pressing the electric wire towards the bottom plate before the second die crimps the crimping pieces. 
     Further, since the second die presses the electric wire towards the bottom plate, relative displacement of the electric wire and the terminal in the lengthwise direction of the electric wire is prevented. 
     In a terminal crimping apparatus according to the present invention, since the third die is slidably attached to the second die, both the third die and the second die can slide in the direction of approaching and parting the first die with only one driving means. Further, since the third die projects more towards the first die than the second die by an urging device, when both the third die and the second die are moved in the direction of approaching and parting the first die with only one driving device, the third die is still capable of inserting the electric wire in between the pair of crimping pieces before the second die crimps the crimping pieces. Still further since the third die is arranged slidably with the second die and urged by an urging device while the second die crimps the crimping pieces, the third die slides respectively with the second die by the pressing force of the first die repelling the urging force of the urging means. 
     In a terminal crimping apparatus according to the present invention, because the servomotor is used as the driving device for moving the second die and the third die, the second die and the third dies are enabled to moved towards the first die in a sequential steps, in which the third die inserts the electric wire in between the crimping pieces, and the second die crimps the crimping pieces. 
     In a terminal crimping apparatus according to the present invention, because the terminal crimping apparatus is provided with a positioning jig for positioning the terminal, before the third part inserts the electric wire in between the crimping pieces, the electric wire is securely inserted in between the pair of crimping pieces-by the third die. 
     In a terminal crimping apparatus according to the present invention, because the terminal crimping apparatus is provided with a detecting means for detecting whether or not the third part has inserted the electric wire in between the crimping pieces, crimping work could be temporary stopped to prevent any defection, such as an insufficient insertion so that the defection rate of crimping the electric wire to the crimping terminal can be reduced. 
     In a terminal crimping apparatus according to the present invention, because the second die is capable of pressure-contacting the electric wire to the pressure-contact portion of the terminal, it is possible to pressure-contact the electric wire to the pressure-contact portion while crimping the electric wire to the crimping pieces. 
     In a terminal crimping method according to the present invention, because the electric wire is inserted in between the pair of crimping pieces before the crimping work, the electric wire is securely positioned in between the curved crimping pieces. 
     EFFECTS OF THE INVENTION 
     As mentioned above, in the present invention the electric wire can be connected securely to a terminal by crimping, since the electric wire is securely inserted in between the curved crimping pieces. 
     Further, because the electric wire and the terminal are prevented from displacement in relation with each other in the lengthwise direction of the electric wire, the electric wire and the terminal are securely crimped while the electric wire and the terminal maintains a relative position thereof. Therefore, the electric wire with the terminal can be produced in a preferred quality. 
     In the present invention, because both the third die and the second die is moved in the direction of approaching and parting the first die with only one driving unit, the number of components is reduced and the production cost of the terminal crimping apparatus will be reduced. 
     Further when the second die and the third die is moved in the direction of approaching and parting the first die with one driving unit, the third part inserts the electric wire in between the crimping pieces before the second die crimps the crimping pieces and the electric wire is securely crimped with the curved crimping pieces of a terminal. 
     Still further, while the second die crimps the crimping pieces, since the third die slides respectively with the second die with the pressing force of the first die repelling the urging force of the urging means, obstruction of the crimping work by the third die, while the second die crimps the crimping pieces is prevented. Therefore, the electric wire is securely attached to the terminal. 
     In the present invention, because the second die and the third die could be moved towards the first die stepwisely by divided steps, in which the third die inserts the electric wire in between the crimping pieces, and the second die crimps the crimping pieces, the completion of each step could be monitored, whereby the defection rate is reduced and prevents deterioration in the quality. 
     In the present invention, because the third die is capable of inserting the electric wire in between the pair of crimping pieces, the electric wire is securely crimped to the terminal. 
     In the present invention, because the terminal crimping apparatus is provided with the detecting means for detecting weather or not the third part has inserted the electric wire in between the crimping piece, the defection while crimping the electric wire to the crimping terminal is reduced. 
     In the present invention, because the wire is pressure contacted to the pressure contact portion during the crimping work of the electric wire to the crimping pieces, and the braid conductor to the crimping piece, and while pressure-contacting the core to the pressure contact portion, it is possible to crimp a shielded wire (as the electric wire) to a terminal for a shielded wire in one step. Therefore, the crimping work (the shielded wire to the terminal for a shielded wire) is done in one process and prevents an increase in the work step. 
     In the present invention, because the electric wire is securely positioned in between the curved crimping pieces, the electric wire is securely crimped to the terminal.

The second crimper  48   b  moves towards the sheath crimping pieces  27  and bends the sheath crimping pieces  27  in the direction of approaching the bottom plate  20  and the sheath crimping pieces  27  crimps the insulating sheath  7  of the shielded wire  2 . 
     The positioning mold  50  is supported by the RAM  49 , slidably in the vertical direction. Namely, the positioning mold  50  is arranged slidable to the crimper  48 . A part of the positioning mold  50  projects from the RAM  49  towards the anvil  47  and is prevented from falling off downward from the RAM  49  by the RAM  49  and others. The positioning mold  50  is shaped in a pole-shape, extending in the vertical direction. The positioning mold  50  is urged towards the plug  3  of the anvil  47  by a sprig  56  acting as an urging means. When the anvil  47  and the crimper  48  is in a position distanced apart from each other, the positioning mold  50  projects more from the RAM  49  towards the anvil  47  than the crimper  48   a ,  48   b.    
     Further, as shown in  FIG. 7  the positioning mold  50  faces the plug pin  8  of the plug  3 , which is placed on the anvil  47 , along in the direction of the anvil  47  and the crimper  48  approaching to and parting from and with each other, namely, in the vertical direction. 
     As shown in  FIG. 7 , at the end near the anvil  47  of the positioning mold  50  a positioning dent  57  is arranged. The positioning dent  57  is dented at the surface end, near to the anvil  47  of the positioning mold  50 . When the RAM  49  descends and the anvil  47  and the crimper  48  approaches each other, the plug pin  8  of the plug  3  which is placed on the anvil  47  is positioned inside the positioning dent  57 . When the RAM  49  descends before the wire inserting mold  51  inserts the braided conductor  6  of the shielded wire  2  in between the pair of crimping pieces  24 , and before the crimper  48   a ,  48   b  crimps the crimping pieces  24 , 25 , 27 , the positioning mold  50  positions the plug pin  8  of the plug  3  inside of the positioning dent  57 , placing the plug pin  8  of the plug  3  between the anvil  47 . Which means that the positioning mold  50  positions the plug  3  by putting the plug pin  8  of the plug  3  between the anvil  47 . 
     The wire-inserting mold  51  is attached to the RAM  49  slidably in the vertical direction. Namely, the wire-inserting mold  51  is arranged slidable to the crimper  48 . The wire-inserting mold  51  is prevented from falling off from the RAM  49 , by the RAM  49  supporting the wire-inserting mold  51  with a part of the wire-inserting mold  51  supported in a position projecting towards the anvil  47 . The wire-inserting mold  51  is urged towards the plug  3  which is placed on the anvil  47  by an urging means, such as the spring  58 . The wire-inserting mold  51  is placed between the crimpers  48   a ,  48   b . When the anvil  47  and the crimper  48  is in a position distanced apart from each other, the wire-inserting mold  51  projects from the RAM  49  towards the anvil  47  more than the crimpers  48   a ,  48   b , and projects less towards the anvil  47  than the positioning mold  50  from the RAM  49 . 
     Further, the wire-inserting mold  51  is directed in the direction of the anvil  47  and the crimper  48  approaching and parting, vertically facing the space between the crimping portions  21 , 22  of the plug  3 , which is placed on the anvil  47 . In other words, the wire-inserting mold  51  approaches to and parts from the space between the crimping portions  21 , 22  of the plug  3 , which is placed on the anvil  47 . 
     As shown in  FIG. 9 , the wire pressing mold  51  consists of, a pair of parallel portions  59  positioned parallel with each other, and a linking plate  60  which links the pair of parallel portions  59  together, and a wire inserting portion  61 . The lengthwise direction of the parallel portion  59  is parallel with the vertical direction. The linking portion  60  links the lower portion of each of the parallel portion  59 . The wire inserting portion  61  is arranged substantially in the middle of the linking portion  60 , projecting from the linking portion  60  towards the anvil  47 . A wire positioning dent  62  is arranged on the wire inserting portion  61 . The wire positioning dent  62  is dented in an arc shape at the edge near towards the anvil  47  of the wire inserting portion  61 . When the RAM  49  descends and the anvil  47  and the crimper  48  moves close with each other the braid conductor  6  exposed at the end of the shielded wire  2  is held by a chuck  69  of a wire carrying device  31  and positioned inside of the wire positioning dent  62 . 
     When the RAM  49  descends, the wire-inserting mold  51  presses the braided conductor  6  of the shielded wire  2 , which is held by the chuck  69  in the direction of the plug  3 , placed on the anvil  47 . Before the crimpers  48   a ,  48   b  crimps the crimping pieces  24 ,  25 ,  27 , the wire-inserting mold  51  inserts the braid conductor  6  of the shielded wire  2  between the pair of crimping pieces  24  by pressing the braided conductor  6  of the shielded wire  2  towards the bottom plate  23 . 
     A wide portion  63  and a narrow portion  64  is arranged on one of the parallel portion  59   a  of the wire inserting mold  51 , and the inner edges of the wide portion  63  and the narrow portion  64  faces the other parallel portion  59   b  of the wire inserting mold  51 , and are arranged in one plane. Needless to say, the wide portion  63  is arranged wider in width than the narrow portion  64 . On one of the parallel portion  59   a  a cut out is arranged by cutting out a part of the outer edge of the parallel portion  59   a.    
     The pressure-contact mold  52  is formed into a plate shape and fixed to the RAM  49 . The pressure-contact mold  52  projects more towards the anvil  47  than the RAM  49 . The pressure-contact mold  52  faces the anvil  47  along the vertical direction while facing the conductor core  4  exposed at the end of the shielded wire  2 , which is fixed to the chuck  69 . The pressure-contact mold  52  is directed towards the pressure-contact portion  12  of the plug  3  on the anvil  47  in the vertical direction (i.e. in the direction of the anvil  47  and crimper  48  approaching and parting) and inserts the conductor core  4  of the shielded wire  2  in the pressure-contact portion  12 . 
     When the RAM  49  moves up and down, the pressure-contact mold  52  is moved in the direction of approaching and parting the pressure-contact portion  12  of the plug  3 . The pressure-contact mold  52  crimps the conductor core  4  with the pressure-contact portion  12  by approaching together with the crimper  48 , towards the anvil  47  and inserts the conductor core  4  of the shielded wire  2 , which is fixed to a chuck  69 , in between the slit  15  of the pressure-contact blade  14  of the pressure-contact portion  12 . 
     As the structure mentioned, the applicator  30  moves the anvil  47  and the crimper  48  close with each other with the driving force of the servomotor  38 , and the positioning mold  50  positions the plug  3  on the anvil  47 , and then, the applicator  30  further drives the servomotor  38 , moving the anvil  47  and the crimper  48  close with each other and inserts the braided conductor  6  of the shielded wire  2  which is fastened to the chuck  69  of the wire carrying device  31 , in between the pair of inner crimping pieces  24  of the braid crimping portion  21  by pressing the braided conductor  6  of the shielded wire  2  with the wire inserting mold  51  towards the direction of the bottom plate. 
     Then, the applicator  30  further drives the servomotor  38 , moving the anvil  47  and the crimper  48  close with each other, and crimps the braid conductor  6  of the shielded wire  2  and the insulating sheath  7  to the plug  3 , by bending the crimping pieces  24 ,  25 , 27  towards the direction of the bottom plate  20 , 23  with the crimpers  48   a ,  48   b , while inserting the conductor core  4  of the shielded wire  2  in between the slit  15  of the pressure-contact blade  14  of the pressure-contact portion  12 , with the pressure-contact mold  52 . As mentioned, by the driving force of the servomotor  38  the applicator  30  moves the anvil  47  and the crimper  48  close with each other while an end of the shielded wire  2  and the plug  3  is placed between the anvil  47  and the crimper  48 , and crimps an end of the shielded wire  2  to the plug  3 . 
     While doing so, the crimping pieces  24 , 25  crimps the braided conductor  6  of the shielded wire  2  by bending the crimping pieces  24 ,  25  of the crimping portion  21  towards the bottom plate  20 ,  23 , with the first crimper  48   a . The sheath crimping pieces  27  crimps the insulating sheath  7  of the shielded wire  2  by the second crimper  48   b  bending the sheath crimping pieces  27  towards the bottom plate  20 . 
     The distance between the crimper  48   a ,  48   b  and the anvil  47  changes in accordance to the outer diameter of the plug  3  and the shielded wire  2 . For instance, when crimping an electric wire with a relatively large outer diameter, the crimpers  48   a ,  48   b  and the anvil  47  will be relatively distanced apart, and when crimping an electric wire with a relatively small outer diameter, the distance between the crimper  48   a ,  48   b  and the anvil  47  will be relatively close. 
     As shown in  FIG. 2 , a wire carrying device  31  consists of, a vertical wall  65 , a linier guide  66 , a driving means (not shown) for the sliding movement, a fluctuating cylinder  67 , a chuck cylinder  68 , and the pair of chuck  69 . 
     The vertical wall  65  is arranged as standing vertically from the bottom plate  35  of the main body  28 . The linier guide  66  has a rail  70  and a slider  71 . The rail  70  extends in a straight line. The rail  70  is attached to the vertical wall  65 . The lengthwise direction of the rail  70  is parallel with the horizontal direction. The slider  71  is attached to the rail  70 , slidably along the lengthwise direction of the rail  70 . The driving means for the sliding movement moves the slider  71  in the lengthwise direction of the rail  70 . 
     The fluctuating cylinder  67  has a cylinder body  72  and a rod  73 , which is arranged free to move up and down from the cylinder body  72 . The cylinder body  72  is attached to the slider  71  of the linier guide  66 . The cylinder body  72  is attached to the slider  71  in a position where a projecting rod  73  moves downward in the vertical direction from the cylinder body  72 . 
     The chuck cylinder  68  consists of, a cylinder main body  74 , and a pair of chuck rods  75 . The cylinder main body  74  is attached to the projecting rod  73  of the fluctuating cylinder  67 . The pair of chuck rods  75  extending parallel with each other in a straight line. The chuck cylinder  68  moves each of the chuck rods  75  in the direction of approaching and parting each other. The chuck cylinder  68  is arranged in a position where the pair of chuck rods  75  extends downward from the cylinder main body  74 , and the longitudinal edge of the chuck rods  75  are positioned parallel with the vertical axis. The chucks  69  are each attached to the chuck rods  75 . The insulating sheath  7  of the shielded wire  2  is put in between the pair of chucks  69 , and the chuck cylinder  68  moves the pair of chucks  69  in the direction of approaching and parting each other. 
     The wire carrying device  31  with the aforementioned structure moves the chuck cylinder  68  along the rail  70  of the linear guide  66  along the lengthwise direction of the rail  70 , while the projecting rod  73  of the fluctuating cylinder  67  extends and retracts. Each one of the pair of chuck rods  75  of the chuck cylinder  68  moves in the direction of approaching to and parting from each other and places the shielded wire  2  with the insulating sheath  7 , or the braided conductor  6  removed at the end, which is held by a rod (not shown) in between the chucks  69 . Thereafter, the wire carrying device  31  carries the shielded wire  2  from the rod  73  to the applicator  30  by the chuck cylinder  68  moving along in the longitudinal length of the rail  70  of the linear guide  66 . Thereafter, an end of the shielded wire  2 , which is held between the chuck  69  is positioned on top of the plug  3 , which is placed on the anvil  47 , by the wire carrying device  31 . Likewise, the wire carrying device  31  carries the shielded wire  2 , one by one from a rod (not shown) to the applicator  30 . 
     As shown in  FIG. 7 , the first sensor  32  is arranged on the anvil  47 . In the figure, the first sensor  32  is a proximity switch, which detects whether or not the positioning mold  50  has correctly positioned the plug  3  onto the anvil  47 . The first sensor  32  detects the existence of the positioning mold  50  when the positioning mold  50  correctly positions the plug  3  inside the positioning dent  57  having the plug  3  abutting against the anvil  47 . The first sensor  32  does not detect the existence of the positioning mold  50  when the positioning mold  50  fails to position the plug  3  correctly inside the positioning dent  57 , and when the plug  3  is distanced from the anvil  47 . The first sensor  32  detects whether or not the positioning mold  50  has positioned the plug  3  inside the positioning dent  57  or if the plug  3  is positioned onto the anvil  47 , by detecting the existence of the positioning mold  50 . 
     As shown in  FIG. 9 , a second sensor  33  is attached to an attachment  79  of a device body  28 . The sensor attachment  79  is fixed to the device body  28 , aligned along a radial direction of the plug  3 , which is placed on the anvil  47 , and also aligning with one of the parallel portion  59   a  having a wide portion  63  and a narrow portion  64  for the wire-inserting mold  51 , namely, the parallel portion  59   a  with a cut-out. 
     The second sensor  33  is arranged in a position aligning with one of the parallel portion  59   a  of the wire inserting mold  51  and the plug  3 , namely, in the radial direction of the shielded wire  2 . Further, the second sensor  33  is placed in between the anvil  47  and the wire-inserting mold  51  which is in a positioned furthest apart from the anvil  47  vertically (in the direction of anvil  47  and crimper  48  approaching and parting). 
     In the figure, the second sensor  33  is a proximity switch detecting whether or not the wire inserting mold  51  is in a position where the braided conductor  6  of the shielded wire  2  is inserted between the pair of crimping pieces  24  of the braid crimping portion  21 . The second sensor  33  detects the existence of the wide portion  63 , when the braided conductor  6  of the shielded wire  2  positioned inside of the wire positioning dent  62  by the wire inserting mold  51 , is inserted in between the pair of crimping pieces  24 , and when the wide portion  63  of one of the parallel portion  59   a  of the wire inserting mold  51  faces the second sensor  33 . 
     The second sensor  33  does not detect the existence of the wide portion  63 , when the braid conductor  6  of the shielded wire  2  placed inside of the wire positioning dent  62  by the wire inserting mold  51 , runs on to one of the crimping piece  24  and the narrow portion  64  of one of the parallel portion  59   a  of the wire inserting mold  51  faces the second sensor  33 . The second sensor  33  detects whether or not the braided conductor  6  of the shielded wire  2  is correctly inserted between the pair of inner crimping pieces  24  by detecting the existence of the wide portion  63  of the wire-inserting mold  51 . 
     The control device  34  is a computer with the well-known ROM, RAM, CPU, which is connected to the mentioned servomotor  38  of the actuating portion  29 , or with the sensors  32 , 33  and such, which controls the connected devices and controls the terminal crimping apparatus  1  as a whole. 
     The ROM memorizes the program movement of the CPU (i.e. the terminal crimping apparatus  1 ). The RAM temporary contains the data, while the CPU executes an operation. The CPU commands the terminal crimping apparatus  1  to operate accordingly with the programmed movement, memorized by the ROM. When crimping the plug  3  to the end of a shielded wire  2 , the CPU first drives the servomotor  38 , moving the RAM  49  towards the anvil  47  to a place where the positioning mold  50  places the plug  3  into the positioning dent  57 , and the plug  3  abutting against the anvil  47 . 
     When the CPU receives an information indicating the existence of the positioning mold  50 , detected and sent by the first sensor  32 , the CPU further drives the servomotor  38  and moves the RAM  49  towards the anvil  47 . If the CPU does not receive an information indicating the existence of the positioning mold  50  from the first sensor  32 , the CPU stops the servomotor  38  and sends a signal of an error (indicating the plug  3  not being positioned by the positioning mold  50 ) to an output device connected to the control device  34 . The CPU then commands the output device to output a signal of error indicating the plug  3  not being positioned correctly by the positioning mold  50 . 
     The CPU further drives the servomotor  38  and moves the RAM  49  towards the anvil  47  to a place where the wire inserting mold  51  inserts the braid conductor  6  of the shielded wire  2 , which is placed inside the wire positioning dent  62 , in between the pair of crimping pieces  24 . 
     When the CPU receives an information indicating the existence of the wide portion  63  of one of the parallel portion  59   a  of the wire inserting mold  51 , detected and sent by the second sensor  33 , CPU further drives the servomotor  38 , moving the RAM  49  towards the anvil  47 . If the CPU does not receive an information indicating the existence of the wide portion  63  on one of the parallel portion  59   a  of the wire inserting mold  51  from the second sensor  33 , the CPU stops the servomotor  38  and sends an information of an error (indicating the wire inserting mold  51  has failed to insert the braided conductor  6  of the shielded wire  2  in between the pair of inner crimping piece  24 ) to the output device. The CPU then commands the output device to output a signal of an error, indicating the wire-inserting mold  51  has failed to insert the braided conductor  6  of the shielded wire  2  in between the pair of inner crimping piece  24 . 
     The CPU further drives the servomotor  38  and crimps the shielded wire  2  with the plug  3 , by bending the crimping pieces  24 ,  25 ,  27  with the anvil  47  and the crimper  48 . The CPU then drives the servomotor  38 , and parts the anvil  47  and the crimper  48  away from each other. By this way, the CPU drives the servomotor  38  in sequence and moves the anvil  47 , the crimper  48 , and the wire-inserting mold  51 , closer in accordance to each of the working steps, in which the wire inserting mold  51  inserts the braided conductor  6  of the shielded wire  2  between the pair of crimping pieces  24 , and the crimper  48  crimps the crimping pieces  24 ,  25 ,  27 . 
     The procedure of crimping an end of the shielded wire  2  to the plug  3  by the aforementioned terminal crimping apparatus  1  will now be explained. As shown in  FIGS. 2 and 3 , by using the servomotor  38 , the anvil  47  and the crimper  48  are distanced furthest apart while one plug  3  is being placed onto the anvil  47 . At the same time, the crimping portion  12  (i.e. an opening) arranged on the main body  13  of the plug pin  8  is placed on the opposite side of the pressure-contact mold  52  and the crimping pieces  24 , 25  of the braid crimping portion  21  is placed on the opposite side of the crimper  48   b . The wire carrying device  31  places an end of a single shielded wire  2  which is taken from a rod between the anvil  47  and the crimper  48 . Further, the positioning mold  50  is spaced apart at the opposite side of the plug  3  placed on the anvil  47 , as shown in  FIG. 7 , and the wire inserting mold  51  is also spaced apart at the opposite side of the plug  3  placed on the anvil  47 , as shown in  FIG. 9 . 
     The CPU of the control device  34 , then moves the servomotor  38  of the applicator  30 , gradually moving the anvil  47  and the crimper  48  close together. Then, the positioning mold  50  gradually approaches towards the plug  3  placed on the anvil  47 , and gradually inserts the plug  3  into the positioning dent  57 . The plug  3  inserted into the positioning dent  57  is then positioned by the positioning mold  50  to the anvil  47 . The first sensor  32  then detects the positioning mold  50  has placed the plug  3  in position of the anvil  47 , and the CPU of the control device  34  further drives the servomotor  38 , further moving the anvil  47  and the crimper  48  close with each other. 
     When the plug  3  is not correctly positioned on the positioning dent  57  and placed between the positioning mold  50  and the anvil  47 , the positioning mold  50  presses the plug  3  placed on the anvil  47  in the direction of the RAM  49 , whereby sinks the plug  3  into the RAM  49 . Thereupon, the first sensor  32  detects the plug  3  not correctly positioned by the positioning mold  50  onto the anvil  47 , and the CPU of the control device  34  stops the servomotor  38 . Accordingly, the CPU commands the output device to output a signal o error, indicating the plug  3  not correctly positioned to the anvil  47 . 
     When the first sensor  32  detects that the positioning mold  50  has positioned the plug  3  onto the anvil  47 , the wire inserting mold  51  abuts on the braided conductor  6  of the shielded wire  2 , and the wire inserting mold  51  positions the braided conductor  6  of the shielded wire  2 , which is held by the chuck  69 , into the wire positioning dent  62 , as shown in  FIG. 4 . Then the CPU of the control device  34  further drives the servomotor  38  and the wire inserting mold  51  presses the braided conductor  6  of the shielded wire  2  towards the bottom plate  23 , whereby the braided conductor  6  of the shielded wire  2  is inserted in between the pair of inner crimping pieces  24  of the crimping portion  21 , as shown in  FIGS. 5 and 10 . 
     The second sensor  33  will not detect the existence of the wide portion  63  of one of the parallel portions  59   a  of the wire-inserting mold  51  and detects the braided conductor  6  of the shielded wire  2  which is inserted in between the pair of inner crimping pieces  24 . The CPU of the control device  34  then further drives the servomotor  38  to move the anvil  47  and the crimper  48  close with each other. 
     When the braided conductor  6  of the shielded wire  2  is not positioned in the wire positioning dent  62  as shown in  FIG. 11 , the braided conductor  6  runs onto one of the pair of crimping pieces  24 , and the braided conductor  6  of the shielded wire  2  will be put in between one of the pair of inner crimping pieces  24 , and the wire pressing mold  51  presses the braided conductor  6  more towards the RAM  49  than when the braided conductor  6  is correctly inserted between the pair of inner crimping pieces  24  and sinks the braided conductor  6  into the RAM  49 . The second sensor  33  detects the existence of the wide portion  63  of one of the parallel portion  59   a  of the wire inserting mold  51 , and infers that the wire pressing mold  51  has not pressed the braided conductor  6  of the shielded wire  2  correctly between the pair of inner crimping piece  24 , and the CPU of the control device  34  stops the movement of the servomotor  38 . The CPU of the control device  34  commands the output device to send a signal of an error, indicating the wire-inserting mold  51  has failed to insert the braided conductor  6  of the shielded wire  2  correctly in between the pair of inner crimping pieces  24 . 
     When the wire inserting mold  51  inserts the braided conductor  6  of the shielded wire  2  between the pair of inner crimping pieces  24 , the pressure-contact mold  52  presses the conductor core  4  of the shielded wire  2  towards the crimping portion  12 . When the second sensor  33  detects the wire inserting mold  51  inserting the braided conductor  6  of the shielded wire  2  between the pair of inner crimping pieces  24  (shown in  FIG. 6 ), the CPU of the control device  34  further drives the servomotor  38 , and the crimper  48   a ,  48   b  crimps the crimping pieces  24 , 25 , 27  and the pressure-contact mold  52  presses the conductor core  4  in between the slit  15  of the crimping blade  14  of the crimping portion  12 . 
     The aforementioned terminal crimping apparatus  1 , crimps the plug  3  to an end of the shielded wire  2  as explained. When the crimping work of the plug  3  to an end of the shielded wire  2  is completed, the CPU of the control device  34  of the terminal crimping apparatus  1  separates the anvil  47  and the crimper  48  apart, by controlling the servomotor  38 . After separating the anvil  47  and the crimper  48  apart, the wire carrying device  31  carries an end of a next shielded wire to the applicator  30 , and the next plug  3  is positioned onto the anvil  47  and crimps the next plug  3  to an end of the next shielded wire  2 . 
     The aforementioned positioning mold  50  does not obstruct the crimper  48   a ,  48   b  crimping the crimping pieces  24 ,  25 ,  27  by sliding in the direction of sinking inside of the RAM  49 , while the plug  3  is positioned on the anvil  47 , and while the crimper  48   a ,  48   b  crimps the crimping pieces  24 ,  25 ,  27 . Further, the mentioned wire inserting mold  51  does not obstruct the crimping work of the crimpers  48   a ,  48   b  by sliding in the direction of sinking inside of the RAM  49  while the braided conductor  6  of the shielded wire  2  is inserted between the pair of crimping pieces  24  and the crimpers  48   a ,  48   b  crimps the crimping pieces  24 ,  25 ,  27 . 
     In the embodiment, the shielded wire  2  is securely inserted in between the curved crimping pieces  24  by the crimper  48  pressing the shielded wire  2  towards the bottom plate  23  before crimping the crimping pieces  24 ,  25 ,  27 , and by having the wire pressing mold  51 , which inserts the shielded wire  2  in between the pair of crimping pieces  24 . Therefore, the shielded wire  2  can be crimped to the plug  3  securely. The embodiment is capable of crimping and pressure-contacting simultaneously by the crimper  48  pressing the shielded wire  2  towards the bottom plate  23  before the crimper  48  crimps the crimping pieces  24 ,  25 ,  27 . 
     Still further, the shielded wire  2  and the plug  3  are prevented from moving out of their relative position in the lengthwise direction of the shielded wire  2 , by the wire inserting mold  51  inserting the shielded wire  2  towards the bottom plate  23 . Therefore, it is possible to securely crimp the shielded wire  2  to the plug  3  while maintaining a desired position in relation with each other. 
     Accordingly, the present invention enables to produce a plug  3  having a shielded wire  2  with the quality desired. 
     Since the wire inserting mold  51  is arranged slidably to the crimper  48 , both the wire inserting mold  51  and the crimper  48  can be moved in the direction of approaching to and parting from the anvil  47  with only one servomotor  38 , and reduces the number of components used in the terminal crimping apparatus  1 . Therefore, the production cost of the terminal crimping apparatus  1  is reduced. 
     By the wire inserting mold  51  projecting more towards the anvil  47  than the crimper  48 , the wire inserting mold  51  is enabled to insert the shielded wire  2  in between the pair of crimping pieces  24  before crimping the crimping pieces  24 , 25 , 27 , and both the crimper  48 , and the wire inserting mold  51  are being moved towards the direction of approaching and parting the anvil  47  by the servomotor  38 . Therefore, it is possible to securely crimp the shielded wire  2  to the plug  3  with the curved crimping pieces  24 . 
     Moreover, since the wire inserting mold  51  is slidably arranged to the crimper  48 , and slides when the crimper  48  is urged by a spring  58  while crimping the crimping pieces  24 , by the wire inserting mold  51  pressed by the anvil  47 , repelling the urging force of the spring  58  and sliding against the crimper  48 , obstruction by the wire-inserting mold  51  during the crimping work (the crimper  48  crimping the crimping piece  24 ) is prevented. Consequently, enables to securely attach the shielded wire  2  to the plug  3 . 
     Since a servomotor  38  is used as the driving means for moving the crimper  48  and the wire inserting mold  51 , the crimper  48  and the wire inserting mold  51  can be moved in sequences, in which, the crimper  48  inserts the shielded wire  2  in between the crimping pieces  24 , and the crimper  48  crimping the crimping pieces  24 . Accordingly, completion of each work phase can be monitored, enabling to reduce the defection rate in the finished product (the crimped shielded wire  2  equipped with a plug  3 ), preventing deterioration in the quality of the wire. 
     Since the wire inserting mold  51  has a positioning mold  50  which positions the plug  3  before the shielded wire  2  is inserted in between the inner crimping piece  24 , the shielded wire  2  is securely inserted in between the pair of inner crimping pieces  24  of the plug  3 . Therefore, the shielded wire  2  will be securely crimped to the plug  3 . 
     Since the wire inserting mold  51  has a second sensor  33 , which detects weather or not the shielded wire  2  is securely inserted in between the crimping pieces  24  and enabling to temporary stop the work before any crimping failure occurs and reduces the defection rate of crimping the shielded wire  2  to the plug  3 . 
     Since the pressure-contact mold  52  is capable of pressure-contacting the conductor core  4  of the shielded wire  2  to the pressure-contact portion  12  of the plug  3 , it is possible to crimp the conductor core  4  of the shielded wire  2  to the pressure-contact portion  12 , while crimping the shielded wire  2  with the crimping pieces  24 ,  25 ,  27 , at the same time, whereby the shielded wire  2  is crimped to a plug  3  of the shielded wire  2  in one sequence. Therefore, it is possible to attach the shielded wire  2  to the plug  3  of the shielded wire  2  in one step, reducing the number of work sequence. 
     By the aforementioned embodiment, a terminal crimping method explained from hereinunder can be acquired. 
     A terminal crimping method, where a plug  3  including a pair of crimping pieces  24  which stands vertically from a bottom plate  23 , and each of the pair of crimping pieces  24  standing from the bottom plate  23  has a curved portion  26 . The curved portion  26  is arranged at each end of the crimping pieces  24  further from the bottom plate  23  and bended in the direction of approaching each other. 
     After the plug  3  on the surface of the anvil  47  is fixed into position, the shielded wire  2  is inserted in between the pair of crimping piece  24 , and the anvil  47  and the crimper  48  is then moved in the direction of approaching each other and crimps the shielded wire  2  in between the pair of crimping pieces  24 , by bending the pair of crimping pieces  24  towards the direction of the bottom plate  23 . 
     In the aforementioned embodiment, an end of a shielded wire  2  with a conductor core  4  is crimped to a plug  3  including a pressure-contacting portion  12 . The present invention, however, is capable of crimping a braided conductor  6 , or an end of a shielded wire without a conductor core with a conventional crimping terminal, which does not have the pressure-contacting portion. 
     The presented embodiment only represents a typical of an embodiment of the present invention, and does not limit the use of the present invention into the mentioned embodiment. In other words, the present invention can be adapted into various embodiments if not digressed from the scope of the invention.
