Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a crimping tool for crimping terminals for crimping terminals for connecting conductors of electric wires, and particularly to a crimping tool for crimping terminals to prevent crimp terminals from being bent and deformed during crimping. This invention relates to a crimping tool for crimping terminals.

[Prior Art] Conventionally, a crimp terminal crimping tool for crimping a terminal for connecting a conductor of an electric wire as described above has a crimp terminal 2 into which a conductor 1 to be connected is inserted, as shown in FIGS. 5 and 6. When connecting the crimp terminal 2 and the conductor 1, the crimp terminal 2, into which the conductor 1 to be connected is inserted, is placed on the die 8 of the crimping tool. The crimp terminal 2 and the conductor 1 are connected by pushing the plug 9 and crushing the pressed portion 3 of the crimp terminal 2.

[Problems to be Solved by the Invention] Such conventional crimp terminal crimping tools are composed of a die, a plug, and a K for partially crushing the crimp terminal into which the conductor to be connected is inserted. ,
As shown in Figure 7, crimp terminals are curved and deformed toward the side where the plug is pushed in. This deformation is unsightly and reduces product value, and terminals deformed in this way can be used by any other party. It makes installation work difficult, and
In order to prevent moisture from entering the conductor, when the terminal portion and the insulator are covered and sealed with insulating tape or shrink tube, there are problems such as the above-mentioned deformation impairs the sealing performance.

Means for Solving Problem E] In order to eliminate the problems in the conventional method described above, the present invention provides a method of crimping terminals for connecting conductors, as shown in FIGS. 1, 2, and 3. The crimping end is equipped with members 6 and 7 that hold down both sides 4 and 5 in the longitudinal direction of the crushed portion 3 of the crimp terminal 2 into which the conductor 1 to be connected is inserted.

[Function] According to the means of the present invention described above, the crimp terminal 2 into which the conductor 1 to be connected is inserted is placed on the die 8 of the crimp tool,
Both sides 4 in the longitudinal direction of the crushed portion 3 of the crimp terminal 2
and 5 are held down by holding members 6 and 7. After that, push in the plug 9 and press the crushed part 3 of the crimp terminal.
Connect crimp terminal 2 and conductor 1 by crushing.

In this case, since both sides of the crushed portion 3 of the crimp terminal 2 are pressed down by the pressing members 6 and 7, the crimp terminal 2 does not curve and deform as shown in FIG.

[Example] The present invention will be explained below with reference to embodiments shown in the drawings.

Figures 1, 2 and 3 show an embodiment of the crimp terminal crimping tool of the present invention, which is a die for partially crushing the crimp terminal 2 into which the conductor 1 to be connected is inserted. 8 and a plug 9 are provided, and holding members 6 and 7 are provided on both sides of the plug 9 to press down the longitudinally adjacent sides 4 and 5 of the crushed portion 3 of the crimp terminal 2.

According to the crimp terminal crimping tool configured as described above, the crimp terminal 2 into which the conductor 1 to be connected is inserted is placed on the die 8 of the crimp tool, and the crimp terminal 2 is pressed in the longitudinal direction of the crushed portion 3 of the crimp terminal 2. 4 and 5 on both sides of the crimp terminal 2 are held down by the semi-cylindrical surfaces of the pressing members 6 and 7 so as not to be crushed, and the plug 9 is pushed in to crush the crushed portion 3 of the crimp terminal 2 to connect the crimp terminal 2 and the conductor 1. . Therefore, in this case, both sides of the pressed portion 3 of the crimp terminal 2 in the longitudinal direction are pressed down by the pressing members 6 and 7, so that the crimp terminal 2 will not be bent or deformed.

E Effects of the Invention] As explained above, the crimp terminal crimping tool according to the present invention is a crimp terminal crimping tool for crimping a terminal for connecting a conductor. Since members are provided to press both sides of the crushed portion in the longitudinal direction, the terminal will not be deformed when the terminal is crimped. This has the excellent effect of not damaging the product value of the crimp terminal.
