Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a crimping tool and a crimping method, and more particularly to a crimping tool for crimping a cable to a crimp terminal.

[0002]

2. Description of the Related Art When a cable is crimped to a crimp terminal and this crimp terminal is connected to a relay terminal plate, a cable or a crimp terminal protection sleeve must be preliminarily crimped to a portion where neither a cable nor a crimp terminal protection sleeve is connected in order to prevent a connection error. An identification code may be entered by magic or the like.

For example, Japanese Unexamined Utility Model Publication No. 3-69864 discloses a process of stamping a portion (cable accommodating portion) of a crimp terminal insulating sleeve which is not crimped before a crimping process.

[0004]

The above prior art has the following problems.

[0005] The first problem is that when an identification code is written using a writing instrument such as magic, the written identification code becomes unreadable depending on the environment.

[0006] The second problem is that the aforementioned Japanese Utility Model Laid-Open Publication No. 3-6986.
According to the engraving method disclosed in Japanese Patent Publication No. 4 (1993), the number of man-hours is increased.

[0007] An object of the present invention is to provide a crimping tool and a crimping method capable of making an easily legible mark over a long period of time and reducing the number of steps.

[0008]

According to a first aspect of the present invention, there is provided a crimping tool including a crimping means and a marking means for performing marking simultaneously with crimping by the crimping means. Also,
A crimping tool according to the present invention, in a second aspect, includes one crimping / engraving means in which a plurality of engravings and a plurality of grooves are arranged in order, and a plurality of engravings or a plurality of grooves provided in one crimping / engraving means. And a second crimping / engraving means in which a plurality of grooves and a plurality of engravings are arranged in order so that they can be fitted to each other.

In the crimping method according to the present invention, a crimped terminal or a portion of a sleeve for protecting the terminal into which a cable is inserted is crimped using a stamp.

According to the present invention, a stamp suitable for the purpose is stamped on the crimp terminal simultaneously with the crimping. That is, the inscription is stamped on the portion to be crimped to be crimped. Therefore, since the stamp is formed by a sufficiently strong pressure (a large pressure necessary for crimping), the stamp is not easily worn, and even if the stamp is exposed for a long period of time or in a severe environment, the content of the stamp is not changed. Easy to read. As a result, a wiring connection error is prevented beforehand, and wiring work efficiency is improved. For example, at the time of replacing the cable, by checking the stamp of the crimp terminal portion, a connection error can be prevented. Further, since the pressing step and the engraving step are performed simultaneously, the number of steps is reduced.
