BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping device for crimping and attaching a chain terminal to a strip of an electric wire, and more particularly to a chain terminal guiding device in this terminal crimping device.

[0002]

2. Description of the Related Art A terminal crimping device of this type already proposed has a structure as shown in FIGS.

That is, in FIG. 3 to FIG. 5, a terminal guide rail 2 for guiding a chain terminal n and an anvil 3 for crimping are continuously provided on a lower portion 1a of a machine frame 1 of the terminal crimping device. An elevator crimper 4 is provided on the machine frame 1 above 3 so as to be able to move up and down so as to press the terminal to the strip of the electric wire W in cooperation with the anvil 3.
The lifting crimper 4 is connected to an output shaft 5 of a driving device (not shown), and the side rod 4a of the lifting crimper 4 is connected.
The cam roller 6 is pivotally mounted on the pin shaft 6a. Further, a swing arm rod 7 is pivotally attached to the machine frame 1 near the cam roller 6 so as to swing freely by a support shaft 8. In the middle of the swing arm rod 7, a cam groove 9 is formed. Are formed so as to loosely fit the cam roller 6. Furthermore, since the cam roller 6 is fitted in the cam groove 9 when the elevating and lowering crimper 4 moves up and down, the swing arm rod 7 is pivotally mounted around the support shaft 8 so as to be swingable. , The lower part 7 of this swing arm rod 7
“A” is vertically extended to above the terminal guide rail 2.
A feed claw 10 is pivotally attached to a lower portion 7a of the swing arm rod 7 by a pin shaft 11, and is elastically urged downward by a coil spring 12 so as to be locked to a chain terminal n and intermittently. A flat holding plate 13 is attached to the terminal guide rail 2 in the vicinity of the feed claw 10 so as to be transferred to the coil spring 1.
A pair of front and rear tightening bolts 15 provided with 4 are attached so as to prevent the chain terminal n from rising. That is, the terminal barrel n1 of the chain terminal n is sandwiched between the terminal guide rail 2 and the pressing plate 13 so as to prevent the coil barrel 14 from floating due to the elasticity of each coil spring 14. Also, the above-mentioned pressing plate 1
3, a spring-like guide plate 16 is laid so as to guide the feed claw 10 and to be engaged with the terminal barrel n1 of the chain terminal n for intermittent transfer. Further, a fixed blade 17 is provided beside the anvil 3, and a flat shear blade 18 is provided on the lifting crimper 4 on the fixed blade 17 so as to separate the bridge n1 of the chain terminal n. Has been. Furthermore, the above-mentioned terminal guide rail 2
At the inlet portion 2a of the, a peculiarity guide plate 19 is attached so as to press the winding peculiarity of the chain terminal n. To guide you smoothly.

Therefore, in the above-mentioned terminal crimping device, a strip is formed in advance on the end of the electric wire W, and when the terminal is crimped to this strip, the electric wire W is clamped by a rotating disk (not shown). It is grasped and intermittently stopped on the anvil 3 and stands by.

On the other hand, in the terminal crimping device described above, the elevating crimper 4 is lowered by the output shaft 5 of the driving device, and the elevating crimper 4 and the anvil 3 simultaneously crimp the chain terminal n waiting on the strip. , The fixed blade 17 and the shear blade 18 separate the bridge n1 of the chain terminal n and lower the cam roller 6 along the cam groove 9 of the swing arm rod 7, so that the swing arm rod 7 is supported. It swings around the shaft 8, and thereby the feed claws 10 transfer the chain terminals n one pitch at a time along the terminal guide rail 2 to the anvil 3.

On the other hand, as shown in FIG. 4A, the terminal barrel n1 of the chain terminal n is connected to the terminal guide rail 2
When the coil springs 14 are sandwiched between the pressing plate 13 and the holding plate 13 with appropriate elasticity so as to prevent them from rising, FIG.
, The terminal barrel n1 of the chain terminal n is accurately and intermittently transferred by the feed claw 10.

[0007]

However, in the above-described terminal crimping device, as shown in FIG. 4B, the terminal barrel n1 of the chain terminal n is located between the terminal guide rail 2 and the holding plate 13. When the coil springs 14 are prevented from being lifted up by the strong elasticity, the terminal barrel n1 is deformed and is not accurately and intermittently transferred, causing a problem.

On the other hand, the terminal barrel n1 of the chain terminal n
5B, the terminal barrel n1 is not deformed when the coil springs 14 are prevented from being lifted between the terminal guide rail 2 and the pressing plate 13 by the weak elasticity, but FIG.
As shown in FIG. 3, there is a problem that the chained terminal n is transferred by the feed claw 10 and the crimping position of the terminal is deviated to cause a problem in the terminal crimping operation.

In order to solve the above-mentioned problems, the present invention provides a terminal crimping device for crimping and attaching a chain terminal to a strip of an electric wire so that the chain terminal is provided between a terminal guide member and a movable guide member. To provide a terminal crimping device capable of improving the quality by eliminating the deformation of the terminal barrel by holding the same while increasing the contact area by pressing and increasing the frictional force to eliminate the deformation of the terminal crimping position. With the goal.
