It is cut and separated from the connecting piece 16 of the carrier 15. The male side chain terminal 10 ′ is obtained by replacing the female terminal 17 of the conventional five female side chain terminal 10 with a male terminal, and the other configurations are the same.

  The terminal crimping is performed between the anvil 5 and the crimper 3 in the same manner as in FIG. 3 (FIG. 3 shows a state before the anvil support 6 is rotated by 90 °, and in FIG. Crimping is performed after rotating 90 °). As shown in FIG. 8, the crimper 3 is moved up and down integrally with the ram 4, and as the ram 4 moves up, the horizontal chain terminals are fed one pitch at a time, and the ram 4 is driven by a driving means 2 such as a vertical cylinder.

  As a driving means for the anvil support base 6 in FIG. 2, a reversible motor, an air pressure type rotary actuator, a horizontal two-stage telescopic air cylinder, a dual cylinder, or the like can be set as necessary.

As in the first embodiment, each of the terminal support portions 49 ₁ and 49 ₂ includes an anvil 5 that is a lower mold, a terminal pressing unit, and a cutter pressing unit. The terminal pressing means is constituted by a vertical pneumatic cylinder 40 (FIG. 8) and a terminal pressing plate 41 or a pressing block connected to the rod 40a of the cylinder 40 as in the conventional example of FIG. The cylinder 40 is disposed not on the terminal support portions 49 ₁ and 49 ₂ but on the device frame 8 (FIG. 8) or the like above the one crimping position C and the two chain terminal supply positions B and B ′ of the anvil support base 6. It is also possible.

  The cutter pressing means is a cutter pressing plate 42 or a pressing block integrally formed with the terminal pressing plate 41 as shown in the conventional example of FIG. When the rod 40a of the cylinder 40 is lowered, the cutter holding plate 42 presses the shear blade (cutter) 24 of the example of FIG. 8 downward to cut the connecting piece 16 of the carrier 15 of the side chain terminals 10 and 10 ′. 17, 17 ′ are separated. The terminal pressing plate 41 and the cutter pressing plate 42 can be provided not on the cylinder 40 but directly on the ram 4 or via a spring.

The shear blade 24 (FIG. 8) as the carrier cutting means is fixedly arranged separately from the anvil support base 6 at the chain terminal supply positions B and B ′ on both the left and right sides as in the conventional example of FIG. Alternatively, as in the conventional example 8, the terminal support portions 49 ₁ and 49 ₂ of the anvil support base 6 may be arranged integrally.

2, the female terminal 17 ₁ of the front end of the horizontal linkage pin 10 of the pre-female in the first contact support member 49 ₁ is disposed on the anvil 5 is fixed in the terminal holding means. Simultaneous to substantially simultaneously the wire 26 to the female terminal 17 in the first contact support member 49 ₁ for crimp connection, the male terminal 17 ₁ of the front end of the horizontal linkage pin 10 'of the male in the second terminal support part 49 ₂ of the right 'Is cut and separated from the carrier 15 by the carrier cutting means.

After draining the female terminal with the wire 26 'from the first terminal support part 49 _1, the anvil support table 6 is rotated 90 ° clockwise as indicated by arrow E in the driving unit, the first terminal support part 49 ₁ is empty At the same time as moving to the chain terminal supply position B of the left female lateral chain terminal 10 in this state, the second terminal support portion 49 ₂ supports the male terminal 17 ₁ ′ and the central first terminal support portion Move to position 49 ₁ (terminal crimping position C).

In this state, the electric wire 26 is crimped and connected to the male terminal 17 ₁ ′ at the second terminal support portion 49 ₂ at the terminal crimping position C, and at the same time or almost simultaneously, the first terminal support portion at the left chain terminal supply position B. 49 ₁ of the female terminal 17 from the carrier 15 the tip of the horizontal chain terminals 10 of the female on the anvil 5 is cut and separated by the carrier cutting means.

Then, after the second male terminal wire with the terminal supporting portion 49 ₂ of the terminal crimping position C is discharged, the anvil support base 6 is rotated 90 ° counterclockwise as indicated by arrow D, first as shown in FIG. 2 again At the same time second terminal supporting portion 49 ₂ is moved to the 'chained terminals supply position B of the' horizontal chained terminals 10 of the male, moving the first terminal support part 49 ₁ is left terminal crimping position C carrying the female terminal 17 To do. Hereinafter, the above process is repeated to efficiently produce two types of electric wires with terminals (in this example, electric wires with male terminals and electric wires with female terminals).

  The electric wires with male terminals and the electric wires with female terminals, which have been alternately crimped at the terminal crimping position C, are alternately discharged from the terminal support portion 49 in a state of being gripped by the clamps of equal pitch on the timing belt, for example. At that time, the terminal pressing means is released. For example, the electric wire with male terminal and the electric wire with female terminal can be separated and taken out from each clamp by a selective clamp in a subsequent process.

  In the embodiment of FIG. 2, the male terminal 17 ′ and the female terminal 17 are used as the two types of terminals. However, for example, different types of female terminals 17 may be used instead of the male terminal 17 ′ (two types of terminals). It is also possible to use a different type of male terminal 17 ′ (to use two types of male terminals 17 ′) instead of the female terminal 17.

Further, the same type of male terminal 17 ′ or female terminal 17 is used instead of different types of terminals (the same type of horizontal chain terminal 10 or 10 ′ is supplied in parallel to the left and right chain terminal supply positions B and B ′. It is also possible. Even in this case, instead of reciprocating the single terminal support portion 49 as in the prior art, the two terminal support portions 49 ₁ , 49 ₂ are simultaneously rotated to move the electric wire with the terminal in a time almost half that of the conventional case. Can be produced.

  In the embodiment of FIG. 2, the two horizontal chain terminals 10 and 10 ′ are used. For example, it is possible to efficiently produce a terminal-attached electric wire using four to four types of horizontal chain terminals. is there.

The horizontal chain terminals 10 and 10 ′ are supplied to the chain terminal supply positions B in the tangential direction of the circular anvil support 6.

  For example, the terminal is cut and separated from the first horizontal chain terminal at the terminal support portion at the left 60 ° position, and is moved to the center crimping position by the clockwise rotation of the anvil support base 6. The terminal is cut and separated from the second horizontal chain terminal at the position, and after the electric wire with the first terminal is discharged, it is moved to the center crimping position by the clockwise rotation of the anvil support base 6, and simultaneously with the crimping, the left 60 ° The terminal is cut and separated from the third horizontal chain terminal at the position, and after the electric wire with the second terminal is discharged, the anvil support base 6 is moved to the center crimping position by the clockwise warping, and simultaneously with the crimping, the left 120 ° The terminal is cut and separated from the fourth horizontal chain terminal at the position, and after the electric wire with the third terminal is discharged, it is moved to the center crimping position by the rotation of the anvil support base 6 in the clockwise direction, and the process of repeating the process is repeated. Same type or Production of the type of the wire with terminals is carried out. The rotation direction and rotation angle of the anvil support base 6 can be arbitrarily set, and which terminal is crimped in which order can be appropriately set.

  In each of the embodiments shown in FIGS. 1 and 2, one side chain terminal (one carrier 15) is used as the side chain terminals 10 and 10 ', but both side chain terminals (two carriers 15) are used. It is also possible to use a book). In this case, the carrier cutting means is disposed before and after the terminal.

  Further, it is possible to perform the crimping process using the vertical chain terminals instead of the horizontal chain terminals 10 and 10 '. The vertical chain terminal is an existing terminal in which front and rear ends of a plurality of terminals 17 and 17 ′ are connected in series by a short connecting piece (carrier) 16. In this case, the terminals 17 and 17 ′ are arranged in the terminal support portion 49 at the terminal supply positions B and B ′ in the vertical direction instead of the horizontal direction in FIGS. 1 and 2, and the electric wire is circular at the terminal crimping position C. Are arranged in the tangential direction. The carrier cutting means uses a shear blade for cutting the connecting piece 16 between the terminals.
