Description

  The present invention relates to a crimp terminal that is cut and separated from a terminal connection body constituted by a band-shaped carrier and a plurality of closed barrel-type crimp terminals protruding from one end side in the width direction of the carrier, and an insulation-coated electric wire The present invention relates to an electric wire crimping apparatus for crimping and connecting an electric wire tip portion where a conductor is exposed from an insulating coating, and a method of manufacturing an electric wire with a crimp terminal.

  As a crimping terminal, an open barrel type crimping terminal in which the crimping part that crimps and connects the tip of the electric wire exposed from the insulation coating of the insulation-coated electric wire opens at the proximal end side of the crimping part. A closed barrel type crimp terminal in which the inside of the crimping part is formed in a hollow shape so that the tip of the electric wire can be inserted into the crimping part from the insertion port is often used.

In the case of the above-described open barrel type crimp terminal, for example, the wire is crimped to the insulation-coated wire using the wire crimping device disclosed in Patent Document 1.
Specifically, the belt-shaped carrier, the crimp terminal arranged regularly at a constant interval on at least one end side in the width direction of the carrier, and a connecting portion that couples the crimp terminal and the carrier are integrally formed. The terminal connection body is fed out from the reel, and the crimp terminal is intermittently sent to the wire insertion position provided in the wire crimping device in order to place the wire tip of the insulated coated wire in the crimp portion of the crimp terminal. And the electric wire front-end | tip part of an insulation coating electric wire is arrange | positioned to the crimping | compression-bonding part of the said crimping terminal arrange | positioned in the said electric wire insertion position, and the said crimping | crimping part is crimped with an anvil (6, 7) and a crimper (14, 15). Thus, the end portion of the electric wire is crimped to the crimping portion to connect the insulated coated wire to the crimping terminal, and the crimping terminal and the carrier are separated by the slide cutter (5). By repeating these steps, it was possible to continuously produce a large number of crimped terminal-attached wires in which an open barrel-type crimp terminal was crimped to the tip of the insulated coated wire.

  However, in the open barrel type crimp terminal manufactured in this way, the tip end of the insulated wire is peeled off and the tip of the wire is placed in a crimped part that opens in a U shape, and the crimped part is caulked. Because of the crimping connection, the wire tip and the inside of the crimping part are exposed in the crimped state. For this reason, in a severe use environment, there is a possibility that the inside of the crimping portion and the conductor surface in the crimping connection portion are corroded and the conductivity is lowered.

  On the other hand, since the closed barrel type crimp terminal has a crimped portion formed in a hollow shape, by inserting the tip of the insulated coated electric wire from the insertion port provided in the crimped portion and crimping the connection The tip of the electric wire inserted inside can be covered without a gap in the entire circumferential direction. Therefore, it is considered that the crimp terminal and the conductor of the insulation-coated electric wire can be reliably conducted, and corrosion that occurs on the inner surface of the crimp portion and the conductor surface at the crimp connection portion can be prevented.

  However, when the electric wire crimping device disclosed in Patent Document 1 is used for a closed barrel type crimp terminal, the carrier is pulled in along with the cutting operation of the slide cutter. The position of the crimp terminal to be crimped (hereinafter referred to as “upstream crimp terminal”) also varies.

  Therefore, when the upstream crimping terminal is disposed at the electric wire insertion position, the position of the electric wire insertion port of the upstream crimping terminal may be shifted from a predetermined position. In particular, the closed barrel type crimp terminal may be formed so that the diameter of the crimp portion of the crimp terminal is substantially equal to the diameter of the covered electric wire inserted into the crimp terminal in order to improve the water-stopping property. If the position of the wire insertion port is deviated from a predetermined position, there is a possibility that the wire cannot be reliably inserted into the upstream crimp terminal. Moreover, since the space | interval of the crimp terminals arrange | positioned along a carrier is narrow with the shrinking | reduction of the crimp terminal in recent years, the crimp terminal of the crimp terminal resulting from a carrier being drawn in with the cutting | disconnection operation | movement of a slide cutter. It is considered that the influence of the position shift becomes large. Therefore, it is considered that the wire tip cannot be reliably inserted into a predetermined position of the crimp portion of the crimp terminal, and the crimp terminal and the wire tip cannot be reliably crimped.

  As shown in FIG. 1, the lower wire guide portion 62 is a lower wire side semicircle 62a which is a semicircle formed on the side surface on the wire side (+ X side) of the terminal cutting separating member 60 so that the arc side is downward. On the terminal-side (−X side) side surface of the terminal cutting separating member 60, and the groove portion of the frustum with the lower terminal-side semicircle 62 b that is a semicircle formed so that the arc-side is on the lower side being the upper surface Form.

  The length of the diameter of the lower terminal side semicircle 62b is equal to the length of the inner diameter of the wire insertion slot 131, and the diameter of the lower wire side semicircle 62a is larger than the length of the diameter of the lower terminal side semicircle 62b. It is large and equal to the length of the diameter of the upper electric wire side semicircle 52a.

  The slit 63 is a hollow cutting / separating means formed in the terminal cutting / separating member 60 in order to cut and separate the female crimp terminal 100 and the carrier 150, and the terminal cutting / separating member 60 is attached to the punch member 50. A slit port 63 a is provided so that the carrier 150 moving along the terminal conveyance guide portion 21 enters the slit 63 at a position before being pressed.

  The slit port 63a is a rectangular entrance provided on the side surface of the terminal cutting / separating member 60 on the −Y direction side so that the carrier 150 that has moved along the terminal conveyance guide portion 21 enters the terminal cutting / separating member 60. The length of the long side is substantially the same as the width of the carrier 150, and the length of the short side is higher than the height of the carrier 150 (see FIG. 6B). The slit port 63a has a configuration in which a portion corresponding to the short side of the rectangle on the −X direction side is opened (see FIGS. 4 and 6B).

  Further, the slit 63 forms a rectangular parallelepiped space with the bottom surface of the rectangle forming the slit opening 63a and the height of the imaginary line L shown in FIG. 4 in the + Y direction, and the carrier 150 is formed in the portion forming the space. A carrier cutting means 64 for cutting the connecting portion, and a connecting portion cutting means 65 for cutting the connecting portion 160, and a space in which the cut carrier piece 150a can be moved is formed in the lower portion of the space, and a slider is formed in the lower portion of the space. 66.

The carrier cutting means 64 is a cutting means provided on the upper side of the slit port 63a formed on the side surface in the -Y direction (see FIG. 1).
On the other hand, the connection part cutting means 65 is a cutting means provided in the upper side part which forms the slit 63 in the -X direction side surface of the terminal cutting separation member 60 (refer FIG. 4).

  In the present embodiment, the carrier cutting means 64 and the connecting portion cutting means 65 are configured as one body, but in the present invention, the carrier cutting means 64 and the connecting portion cutting means 65 are limited to an integrated configuration. It is good also as an aspect comprised as another body instead of being done.

  The slider 66 is a slope provided in a space formed below the slit 63 formed in the terminal cutting / separating member 60 and has a predetermined angle with respect to the carrier 150 as shown in FIGS. Thus, the carrier slice 150a of the cut carrier 150 can be moved to a desired position.

  The wire crimping apparatus 1 having the above configuration can lower the crimper jig 40 and the punch member 50 by the lifting mechanism 22 provided in the base body 20. By lowering the punch member 50, the punch pressing portion 51 of the punch member 50 presses the punch receiving portion 61 of the terminal cutting separation member 60, and at the same time, the upper electric wire side semicircle 52a and the lower electric wire side semicircle 62a The upper terminal side semicircle 52b and the lower terminal side semicircle 62b are in contact with each other.

  Here, as described above, the upper terminal-side semicircle 52b and the lower terminal-side semicircle 62b have the same diameter. Moreover, since the lengths of the diameters of the upper electric wire side semicircle 52a and the lower electric wire side semicircle 62a are also equal, the truncated cone shape formed by combining the punch member 50 and the terminal cutting separation member 60 is directed to the -X side. As a result, a tapered guide portion 70 having a tapered diameter is formed.

  Subsequently, using the wire crimping apparatus 1 having the above-described configuration, the female crimp terminal 100 and the carrier 150 coupled to the terminal connector 10 are cut and separated, and the crimp portion 130 of the female crimp terminal 100 is separated. A manufacturing method for manufacturing the electric wire with crimp terminal 300 in which the tip end side of the covered electric wire 200 is inserted and crimped to connect the female crimp terminal 100 and the covered electric wire 200 will be described with reference to FIGS.

  First, the crimp terminal-equipped electric wire 300 including the terminal arrangement process (step s1), the terminal temporary fixing process (step s2), the carrier separation process (step s3), the electric wire insertion process (step s4), and the electric wire crimping process (step s5). The manufacturing process will be briefly described with reference to FIG.

  First, in the terminal arrangement step (step s1), the female crimp terminal 100 that has moved along the terminal conveyance guide portion 21 is arranged at the electric wire insertion preparation position Po where the tip of the covered electric wire 200 can be moved to a position where it can be inserted. To do. Next, by lowering the crimper jig 40, the female crimp terminal 100 is temporarily fixed by the anvil jig 30 and the crimper jig 40, and the covered electric wire 200 is moved to a position where it can be inserted into the crimp part 130 ( Step s2). Then, by lowering the punch member 50, the terminal cutting / separating member 60 is pressed down, and the female crimp terminal 100 and the carrier 150 are cut and separated, and the punch member 50 and the delicate cutting / separating member 60 insert the electric wire. Is formed (step s3), and the lead wire 210, which is the tip of the covered wire 200, is inserted into the wire insertion port 131 of the female crimp terminal 100 along the taper guide portion 70 (step s4). ). Then, the female crimp terminal 100 into which the covered electric wire 200 is inserted is crimped with the anvil jig 30 and the crimper jig 40, so that the female crimp terminal 100 and the coated electric wire 200 are crimped and connected (step s5).

Hereinafter, each process will be described in detail.
First, the terminal arrangement process (step s1) will be described with reference to FIG.

  In the terminal arrangement step (step s1), the female crimp terminal 100 connected to the carrier 150 through the connecting portion 160 by moving the terminal connecting body 10 in the + Y direction by a carrier feeding mechanism (not shown) is used as the base body 20. Is conveyed in the + Y direction along the terminal conveyance guide portion 21 provided for At this time, since the positioning hole 151 is provided in the carrier 150, when the carrier 150 reaches a predetermined position, the movement of the carrier can be temporarily stopped at that position. Therefore, the female crimp terminal 100 can be intermittently conveyed to the wire insertion preparation position Po.

At that time, as shown in FIG. 6C, the crimper jig 40 is disposed in the upward direction (+ Z direction) of the female crimp terminal 100, and the anvil jig 30 is disposed in the downward direction (−Z direction). Will be placed. In other words, moving the female crimp terminal 100 to the electric wire insertion preparation position Po means moving the female crimp terminal 100 to a position between the anvil jig 30 and the crimper jig 40.
When the female crimp terminal 100 is located at the electric wire insertion preparation position Po, the crimper jig 40 and the punch member 50 are located above the female crimp terminal 100 (see FIG. 6).

Next, the terminal temporary fixing step (step s2) will be described with reference to FIG.
When the female crimp terminal 100 is arranged at the electric wire insertion preparation position Po, the crimper jig 40 is lowered by the lifting mechanism 22 provided in the base body 20, so that the female crimp terminal 100 is crimped. The lower end portion of the crimping portion 130 of the female crimp terminal 100 is placed on the anvil jig 30 by being pressed by the tool 40, and the insulation crimper leg portion is the lower end portion of the insulation crimper 41 and the wire crimper 42. 41a and the wire crimper leg part 42a temporarily fix the crimping part 130 (cover crimping part 132 and conductor crimping part 133) of the female crimp terminal 100 from both sides in the Y direction of the crimping part 130 (see FIG. 7). Accordingly, the anvil jig 30 and the crimper jig 40 are temporarily fixed so that the female crimp terminal 100 is lightly sandwiched, and the female crimp terminal 100 is disposed at a position where the covered electric wire 200 can be inserted into the crimp portion 130. It will be.

Next, the carrier separation step (step s3) will be described with reference to FIGS.
As described above, after the crimper jig 40 is lowered to temporarily fix the female crimp terminal 100, the punch receiving portion 61 is disposed at a position where the punch pressing portion 51 is opposed by lowering the punch member 50. Will be pressed. By pressing the punch receiving portion 61, the terminal cutting / separating member 60 moves downward, and the carrier 150 inserted into the slit 63 through the slit port 63a comes into contact with the upper surface of the slit 63 (illustrated). (Omitted).

When the carrier 150 is in contact with the upper surface of the slit 63, the carrier 150 is in contact with the carrier cutting means 64 provided in the slit 63, and the carrier cutting means 64 is cut by further pressing the terminal cutting separating member 60. Is done. (See FIG. 8 (c)). At this time, since the female crimp terminal 100 is coupled to the coupling portion 160, the female crimp terminal 100 and the carrier 150 are not completely separated (see FIG. 8B).
Note that the cutting of the carrier 150 means shearing by the carrier cutting means 64.

  When the terminal cutting / separating member 60 is further pressed, the connecting portion cutting means 65 comes into contact with the connecting portion 160 that connects the female crimp terminal 100 and the carrier 150, and the connecting portion 160 can be cut (FIG. 9). reference).

  Note that the cutting of the connecting portion 160 means shearing by the connecting portion cutting means 65.

  As described above, by cutting the carrier 150 by the carrier cutting means 64 and cutting the connecting portion 160 by the connecting portion cutting means 65, the female crimp terminal 100 and the carrier 150 can be cut and separated. . The female crimp terminal 100 is supported by the anvil jig 30. The separated piece of the carrier 150 (the carrier piece 150a) is not supported and falls, and moves to a predetermined position on the downstream side along the slider 66 provided below the slit 63 ( (See FIG. 9). As a result, the carrier slice 150a is discharged, and the carrier slice can be prevented from accumulating in the slit. Therefore, after cutting the female crimp terminal 100 and the carrier 150, it is possible to prevent the upstream crimp terminal from moving to the wire insertion preparation position Po.

Next, an electric wire insertion process (step s4) and an electric wire crimping process (step s5) for inserting the covered electric wire 200 into the female crimp terminal 100 will be described with reference to FIGS.
As described above, by lowering the punch member 50 by the lifting mechanism 22, the terminal cutting / separating member 60 can be moved to a position where the female crimp terminal 100 and the carrier 150 can be cut and separated.

  At this time, the upper wire guide portion 52 provided in the punch member 50 and the lower wire guide portion 62 provided in the terminal cutting / separating member 60 are combined with each other in the vertical direction. In this state, a taper guide portion 70 that is a tapered guide that decreases in diameter toward the −X side is configured (see FIGS. 8 to 10).

  Further, by lowering the punch member 50 and the terminal cutting / separating member 60, as shown in FIG. 9A and FIG. 9B, the upper electric wire side semicircle 42b which is a component of the taper guide portion 70 and the lower portion A circle formed by the electric wire side semicircle 52b is a position corresponding to the position of the electric wire insertion port 131. Therefore, by inserting the covered electric wire 200 in the −X-axis direction along the taper guide portion 70, the electric wire tip portion 201 which is the tip portion of the covered electric wire 200 can be inserted into the electric wire insertion port 131 (FIG. 9). And FIG. 10).

  As shown in FIG. 11, the crimping jig 40 is further lowered with respect to the crimping portion 130 into which the covered electric wire 200 has been inserted in this manner, whereby the covered crimping portion 132 is moved by the insulation anvil 31 and the insulation crimper 41. The conductor crimping part 133 can be caulked with the wire anvil 32 and the insulation crimper 41. Thereby, the electric wire 300 with a crimp terminal in which the female crimp terminal 100 and the covered electric wire 200 are crimp-connected can be manufactured. Moreover, since the inside of the slit 63 is vacant by moving the manufactured electric wire 300 with a crimp terminal, the upstream crimp terminal is moved to the wire insertion preparation position Po by moving the carrier 150 along the terminal conveyance guide portion 21. can do.

  As described above, by repeating the terminal arrangement step (step s1) to the wire crimping step (step s5), the wire tip portion 201 where the conductive wire 210 is exposed from the insulating resin 220 at the tip portion of the covered wire 200 is closed. It is possible to manufacture the electric wire 300 with the crimp terminal that is securely inserted into the barrel-type female crimp terminal 100 and crimped to the crimp portion 130 of the female crimp terminal 100, the wire tip portion 201, and the covering portion 202.

  Here, in this embodiment, the carrier 150 is cut by the carrier cutting means 64 and then the connecting portion 160 is cut by the connecting portion cutting means 65, whereby the carrier 150 and the female crimp terminal 100 are cut. However, if the position of the wire insertion slot 131 of the female crimp terminal 100 adjacent to the −Y side is not affected, the carrier 150 does not necessarily have to be cut first.

  For example, the cutting with the connecting portion 160 by the connecting portion cutting means 65 may be cut first, or the cutting of the carrier 150 with the carrier cutting means 64 and the cutting of the connecting portion 160 with the connecting portion cutting means 65 may be performed simultaneously. Also good.

  In the present embodiment, the crimping portion 130 of the female crimp terminal 100 is lightly sandwiched between the anvil jig 30 and the crimper jig 40, and at the same time, the insulation crimper leg 41a and the wire that are the configuration of the insulation crimper 41 The crimping portion 130 is temporarily fixed by the wire crimper leg portion 42 a which is the configuration of the crimper 42. That is, when the anvil jig 30 and the crimper jig 40 are used as temporary fixing means for the female crimp terminal 100, the position of the female crimp terminal 100 is temporarily fixed, and the carrier 150 is cut by the carrier cutting means 64. In addition to preventing the carrier 150 from being easily pulled in the cutting direction, it is possible to obtain an effect that the carrier 150 is easily cut.

  Further, in this embodiment, the carrier cutting means 64 and the connecting portion cutting means 65 are configured to cut perpendicularly to the width direction of the carrier 150 and the connecting portion 160, but the carrier 150 and the connecting portion 160 are cut. Therefore, it is sufficient that the female crimp terminal 100 and the carrier 150 can be cut and separated, and the invention is not limited to the case of cutting perpendicularly to the width direction of the carrier 150 and the connecting portion 160. For example, the carrier 150 may be cut obliquely with respect to the width direction.

  Further, as in the present embodiment, the blade shapes of the carrier cutting means 64 and the connecting portion cutting means 65 do not have to be limited to a linear shape, and other shapes such as a wave shape with respect to the width direction of the carrier 150 and the like. It may be in shape.

  In this embodiment, the female cutting terminal 100 and the carrier 150 adjacent to the upstream side are completely cut by the carrier cutting means 64, but when the covered electric wire 200 is inserted into the female crimping terminal 100. As long as the female crimp terminal 100 and the carrier 150 can be cut and separated, the embodiment is not limited to this embodiment. For example, the cutting by the carrier cutting means 64 is performed in the width direction or the thickness direction of the carrier 150. It is also possible to have a configuration in which a portion is partially cut, and when the connecting portion 160 is cut by the connecting portion cutting means 65, the partially cut portion is bent by a load or the like related to the connecting portion 160.

  As described above, the conductor 210 has the covered electric wire 200 having the electric wire tip 201 exposed from the insulating resin 220 on the tip side, the electric wire insertion port 131 into which the electric wire tip 201 can be inserted, and the electric wire tip 201 is crimped. The wire insertion port 131 of the female crimp terminal 100 arranged in parallel at a predetermined interval to the female crimp terminal 1 connected by crimping to the female crimp terminal 100 including the closed barrel crimp unit 130 to be connected, and the female crimp A belt-like carrier 150 extending in a direction orthogonal to the longitudinal direction of the terminal 100 is connected via a connecting portion 160 and also moved from the terminal connector 10 that moves from the upstream side to the downstream side in the longitudinal direction of the carrier 150. Inserting a wire into the terminal cutting separating member 60 for cutting and separating the mold crimp terminal 100 and the female crimp terminal 100 separated from the terminal connector 10 The female crimp terminal 100 is provided with an anvil 30 and a crimper 40 for crimping the wire tip portion 201 inserted into the crimp portion 130 from 131 and the crimp portion 130, and crimped to the terminal cutting separation member 60 with the anvil 30 and the crimper 40. In contrast, the carrier cutting means 64 for cutting the carrier 150 between the upstream crimping terminal adjacent to the upstream side, the female crimping terminal 100 crimped by the anvil 30 and the crimper 40, and the connecting part 160 for coupling the carrier 150 to each other. The connecting wire cutting means 65 for cutting the wire 210 is securely inserted into the closed barrel-type crimp terminal, with the conductor 210 exposed from the insulating resin 220 at the tip of the covered wire 200. The crimping part 130 of the mold crimping terminal 100 and the wire tip part 201 can be crimped.

  More specifically, the carrier 150 connecting the female crimp terminal 100 and the upstream crimp terminal is cut by the carrier cutting means 64, so that even if the carrier 150 is pulled in by the cutting operation of the carrier cutting means 64, the adjacent upstream Without affecting the carrier 150 of the side crimp terminal, the wire insertion port 131 of the upstream crimp terminal can be prevented from shifting from a predetermined position at the wire insertion position.

  Therefore, the female crimp terminal 1 can securely crimp the hollow crimp portion 130 in the closed barrel type female crimp terminal 100 and the wire tip portion 201 inserted into the crimp portion 130.

  Moreover, as a manufacturing method of manufacturing the electric wire 300 with a crimp terminal using the female crimp terminal 1, the wire insertion port 131 of the female crimp terminal 100 arranged in parallel at a predetermined interval and the longitudinal direction of the female crimp terminal 100 are provided. A band-shaped carrier 150 extending in a direction orthogonal to the terminal is connected via a connecting portion 160, and the female crimp terminal 100 is cut from the terminal connector 10 that moves from the upstream side to the downstream side in the longitudinal direction of the carrier 150. Then, the terminal cutting / separating member 60 that separates the terminal connector 10 and the female crimp terminal 100 is separated and separated (step s3), and the coated wire 200 is inserted into the wire insertion port 131 of the female crimp terminal 100. The insertion step (step s4) of inserting the electric wire tip 201 and the covered electric wire 200 inserted into the crimp portion 130 by the insertion step are connected to the pressure of the female crimp terminal 100. The crimping step (step s5) for crimping to the portion 130 is performed in this order, and the separating step (step s3) is performed by the carrier cutting means 64 using the carrier 150 between the female crimp terminal 100 and the upstream female crimp terminal. The same effect can be obtained by cutting the female crimp terminal 100 and the connecting portion 160 with the connecting portion cutting means 65 while cutting.

  Further, in the wire crimping device 1, terminal cutting and separation in which the female crimp terminal 100 and the carrier 150 are cut when viewed from the direction in which the covered wire 200 is inserted into the wire insertion port 131 of the female crimp terminal 100 by the lifting mechanism 22. In order to retract the member 60 to a position outside the inner diameter of the electric wire insertion port 131, the electric wire tip 201 which is the tip of the covered electric wire 200 can be easily and reliably inserted into the electric wire insertion port 131 of the crimping portion 130. it can.

  More specifically, after the connecting portion 160 is cut by the terminal cutting / separating member 60, the terminal cutting / separating member 60 is retracted to a position outside the inner diameter of the electric wire insertion port 131 by the elevating mechanism 22, so that the terminal cutting / separating member 60 After the carrier 150 and the female crimp terminal 100 are cut and separated, the terminal cutting separation member 60 is not positioned between the wire insertion slot 131 and the tip of the covered wire 200, and the tip of the covered wire 200 is crimped. It can be easily and reliably inserted into the 130 wire insertion slots 131.

  Further, since the carrier cutting means 64 and the connecting portion cutting means 65 are integrally configured as the terminal cutting / separating member 60, the carrier 150 and the connecting portion 160 can be cut in one operation. That is, the female crimp terminal 100 and the carrier 150 can be cut and separated without providing a new mechanism for the connecting portion cutting means 65.

Further, since the cutting direction of the carrier cutting means 64 and the cutting direction of the connecting portion cutting means 65 are the same as the direction in which the terminal cutting separating member 60 is retracted, the configuration of the wire crimping device 1 can be made simple. .

  Furthermore, by using the conductor 210 made of an aluminum-based material as the conductive wire, it is possible to reduce the weight as compared with a covered wire having a wire conductor made of copper wire, and an electric wire with a crimp terminal excellent in electrical conductivity. Can be made.

  Furthermore, the female crimp terminal 100 is provided with a sealing portion 134 in which the opposite end of the wire insertion port 131 in the crimp portion 130 is formed in a flat shape, whereby the covered electric wire 200 is provided in the crimp portion 130. By providing the sealing portion 120 on the side opposite to the side where the electric wire tip portion 201 is inserted, it is possible to ensure a certain water stoppage in the direction opposite to the insertion direction of the electric wire tip portion 201. Therefore, the electric wire with a crimp terminal with higher water-stopping property can be made.

  Further, the terminal cutting / separating member 60 is provided with a slit 63, the carrier cutting means 64 is configured at the upstream end portion of the slit 63, and the connecting portion cutting means 65 is configured at the opposite end portion facing the crimp terminal in the slit 63. In addition, by providing the slit 63 with the slider 66 that inclines downward toward the downstream side, the carrier segment 150a can be discharged by moving the carrier segment 150a downward toward the downstream side. Further, the carrier piece 150a does not stay in the slit 63, and the upstream crimp terminal can smoothly move to the wire insertion position for inserting the wire tip portion 201 of the covered wire 200 in order to crimp the covered wire 200. .
