Description of the Related Art When crimping an electric wire to a terminal fitting, first, a long strip-shaped plate material is punched out by a press, and a predetermined terminal fitting shape is formed from one side edge of an elongated carrier by bending or the like. A chain terminal is obtained by protruding a large number of terminal metal pieces in a cantilever manner in parallel. Then, while the chain terminals are intermittently fed into the automatic machine, the electric wires are sequentially crimped to the respective terminal metal pieces, and the crimped terminal metal pieces are separated from the carrier. As an automatic machine for crimping an electric wire to a terminal metal piece while feeding a chain terminal as described above, Japanese Utility Model Laid-Open No. 5-17981 and Japanese Utility Model Publication No.
No. 31,673. With these automatic machines,
The feed terminal is hooked into the pilot hole formed at a constant pitch in the carrier, and the chain terminal is sent at a constant pitch.When the feed claw returns while sliding on the carrier, the chain terminal follows and goes backward. This is prevented by a braking device. The braking device includes a receiving member for slidingly contacting the lower surface of the carrier, and an elastic pressing member for pressing the upper surface of the carrier to elastically sandwich the carrier between the receiving member and the elastic pressing member. The movement of the chain terminal in the return direction is restricted by frictional resistance between the member and the carrier.

的としている。Since the surface of a general chain terminal is formed by punching a smooth plate material, the surface of the carrier is also smooth. However, when friction is used as a means for preventing the carrier from returning as described above, if the surface of the carrier is smooth, the necessary frictional resistance (braking force) cannot be reliably obtained, and the chain terminal cannot be properly fed. It may stop at a position slightly returned from the position. In this case, at the crimping position, the barrel portion of the terminal metal piece is displaced with respect to the anvil on the automatic machine side, and when the anvil is lowered in this state, the barrel portion is not formed into a shape that properly holds the electric wire, The core wire of the electric wire protrudes from the barrel portion, or the barrel portion cuts into the resin coating of the electric wire so as to break through. In addition, the side edge of the carrier opposite to the terminal metal piece is slid on the guide, but the carrier is moved from the terminal metal piece side to the guide side while the carrier is sent by the feed claw. Since there is no means for pressing the carrier, the carrier may be separated from the guide. If the carrier is displaced in a direction away from the guide, the terminal fitting may not be formed into a normal shape. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to reliably restrict the return movement of a carrier and to reliably position the carrier along a guide.

した。According to a first aspect of the present invention, there is provided a chain terminal in which a large number of terminal metal pieces are cantilevered in parallel from one side edge of an elongated plate-shaped carrier. In the machine, the terminal metal piece is positioned by sliding a side edge of the carrier opposite to the terminal metal piece on a guide means, and the carrier is clamped to restrict return. By being intermittently fed while applying a braking force to the terminal metal piece, a crimping process is performed on the terminal metal piece. A linear non-slip portion that extends obliquely from the terminal metal piece side to the guide means side toward the feed direction is formed.

によって確実に位置決めされる。According to the first aspect of the present invention, even if a force in the return direction acts on the carrier during intermittent feeding in the automatic machine, the linear anti-slip portion is caught by the pinching operation on the carrier. Since a large frictional resistance is generated, the return of the carrier is reliably prevented. Also,
At the time of the feeding operation, a snagging resistance occurs at the linear non-slip portion due to the pinching operation on the carrier,
The hooking resistance acts as a pressing force on the guide means side with respect to the carrier due to the inclination of the linear antiskid portion. Therefore, the carrier is always pressed against the guide means, so that the terminal fitting piece is reliably positioned by the guide means.

加工とが順次に施される。When the lifting / lowering body 24 moves upward and the crimping die 25 and the cutter (not shown) are at a position retracted above the chain terminal 10, the cam roller 26 engages with the upper end of the cam groove 29 to swing. The moving body 27 is in a standby position inclined as shown by a chain line in FIG. In this state, the feed arm 30 is on standby while engaged with the pilot hole 13. When the elevating body 24 moves down from this standby state, the rocking body 27 and the feed arm 3 are engaged by the engagement between the cam groove 29 and the cam roller 26.
0 swings, and accordingly, the feed claw 30A moves to the crimping position side while being engaged with the pilot hole 13, so that
The chain terminal 10 moves by the same distance as the arrangement pitch of the terminal metal pieces 12. Then, the cam roller 26 is moved to the cam groove 29.
After reaching the bent portion (shown by a solid line in FIG. 2), the cam groove 2
Since the lower area of the lower arm 9 is directed in the up-down direction, the swinging body 27 and the feed arm 3 are thereafter moved even if the elevating body 24 moves down.
0 does not swing, so that the chain terminal 10 is held in a fixed position. Then, as the elevating body 24 moves down, the core portion of the terminal of the electric wire W from which the resin coating has been removed is supplied to the barrel portion 12B, and a cutter (not shown) connects the terminal metal piece 12 and the carrier 11 to each other. The part 14 is cut, and at the same time, the crimping die 25 crimps the electric wire W to the barrel part 12B (FIG. 4 shows a crimping step). After crimping, lift 2
After the crimping die 4 moves up and the crimping die 25 separates from the barrel portion 12B and the cam roller 26 reaches the bent portion of the cam groove 29, the swinging body 27 and the feed arm 30 return in the returning direction with the upward movement of the elevating body 24. The feed pawl 30A is disengaged from the engaged pilot hole 13 and slides on the upper surface of the carrier 11 in a direction opposite to the feed direction. Then, the elevating body 24 and the oscillating body 27
Is returned to the original standby position, the feed claw 30A engages with the pilot hole 13 on the rear side in the feed direction and stands by. Thereafter, by repeating the above-described operation, each terminal fitting piece 12
, An electric wire crimping process and a separation process from the carrier 11 are sequentially performed.

Means 32 are provided. The braking means 32 is provided with an L-shaped pressing body 34 placed on the upper surface of a support 33 whose side surface is the guide surface 23, and an adjustment bolt 36 penetrated through a vertical guide hole 35 of the pressing body 34.

The structure is brought into pressure contact. The carrier 11 is elastically sandwiched between the lower surface 38A of the clamping portion 38 and the receiving surface 22, and frictional resistance is generated between the upper and lower surfaces of the carrier 11 therebetween.

ている。The chain terminal 1 is formed by the frictional resistance.
The movement of zero is regulated. In particular, when the feed pawl 30A moves backward while sliding on the upper surface of the carrier 11, a moving force in the return direction acts on the chain terminal 10 which is stationary. It is designed to be kept stationary. However, since the function of regulating the movement by the braking means 32 continues to be exerted even in the step of sending the chain terminal 10, the frictional resistance must not be so large as to hinder the feeding to the chain terminal 10. Therefore, the magnitude of the frictional resistance can be arbitrarily adjusted by changing the screwing amount of the adjusting bolt 36.

When frictional resistance is generated between the lower surface 38A of the pressing portion 38 and the upper surface of the carrier 11 and the receiving surface 22 and the lower surface of the carrier 11 with the feed of the chain terminal 10, the lower surface 38A of the pressing portion 38 The direction of the resistance acting on the chain terminal 10 side from the surface 22 side does not have a fixed directionality, and therefore, the chain terminal 10 moves obliquely to the normal feed direction (the direction parallel to the guide surface 23). Is concerned. However, in the present embodiment, as a countermeasure, means for providing the carrier 11 of the chain terminal 10 with directionality is provided. That is, in the area except for the pilot hole 13 and its periphery on the upper surface and the lower surface of the carrier 11, a linear non-slip portion extending linearly in an oblique direction with respect to the normal feed direction (the length direction of the carrier 11). 15 are formed. The linear non-slip portions 15 are formed of a large number of fine triangular cross-section grooves engraved on both upper and lower surfaces of the carrier 11, and the respective linear non-slip portions 15 are parallel to each other.
The inclination of the linear anti-slip portion 15 with respect to the feed direction is such that the terminal metal piece 1
The direction extends from the two side edges to the guide surface 23 side edge. When the carrier 11 is moved by the feed claw 30 </ b> A, the lower surface 38 </ b> A of the pressing portion 38 and the receiving surface 22 are positioned with respect to the groove edge of the linear non-slip portion 15 by providing the oblique linear non-slip portion 15. This causes a drag, which creates a directional resistance. That is,
Due to the inclination of the linear anti-slip portion 15, the snagging resistance acts as a pressing force against the carrier 11 toward the guide surface 23. As a result, the side edge of the carrier 11 opposite to the terminal metal piece 12 is always pressed against the guide surface 23, and the carrier 11 is positioned in the width direction (the direction perpendicular to the feed direction), so that the terminal The metal piece 12 is securely positioned with respect to the guide surface 23. Further, since the linear anti-slip portion 15 is formed, in addition to the frictional resistance caused by the elasticity of the compression coil spring 37, the pressing portion 38 and the receiving portion are provided between the pressing portion 38 and the receiving surface 22 and the carrier 11. Since a large resistance is generated due to the hooking between the surface 22 and the groove edge of the linear anti-slip portion 15, the function of preventing the chain terminal 10 from loosening is improved. Further, since the linear anti-slip portions 15 are formed on both the upper and lower surfaces of the carrier 11, the reliability of the braking function due to the engagement with the braking means 32 and the function of pressing the carrier 11 toward the guide surface 23 side are also improved. But higher.
