BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping tool for engraving a character on a terminal member while crimping a terminal member on the tip of a conductive wire.

[0002]

2. Description of the Related Art Conventionally, when forming a terminal at the tip of a conductive wire, a method of crimping the terminal member with a terminal crimping tool and crimping to the tip of the conductive wire has been generally used. Figure 9
FIG. 6 is a diagram showing a schematic configuration of a conventional terminal crimping tool. In FIG. 9, the terminal crimping tool 101 includes a grip portion 102, a lever 103, and a terminal insertion port 104. Further, inside the terminal insertion port 104, the fixed jaw 105 and the movable jaw 1
06 is provided.

The movable jaw 106 is connected to the lever 103, and interlocks with the movement of the lever 103, and the terminal insertion opening 1
Slide inside 04. The movable jaw 106 has a groove 106a on the upper surface thereof.

On the other hand, the conductive wire 12 is formed by coating the surface of the conductor portion 12a with an insulator 12b. Further, the terminal member 11 is a sleeve 11 used for crimping with the conductive wire 12.
b and a connecting portion 11a that functions as a terminal.
The sleeve 11b has a cylindrical shape having an inner diameter larger than that of the conductive wire 12, and has a slit in the height direction of the cylinder.

When crimping the terminal member 11 to the conductive wire 12, first, the conductor portion 12a at the tip of the conductive wire 12 is exposed. Next, the exposed conductor portion 12a is covered with the sleeve 11b. Subsequently, the terminal member 11 is inserted into the terminal insertion opening 104, and the slit of the sleeve 11b is placed in alignment with the groove 106a. Next, operate the lever 103 to move the movable jaw 1.

The sleeve 11b is caulked to connect the terminal member 11 to the conductive wire 1.
It can be crimped to 2.

By the way, it is general to use a plurality of conductive wires for the wiring of the device. Further, when connecting a plurality of devices, the number of conductive wires increases dramatically. Moreover, when a long conductive wire is used, it is difficult to confirm the connection source of the conductive wire. Therefore, in order to properly connect all the conductive wires, it is possible to confirm the information of the connection destination at the tip of the conductive wires, thereby reducing the labor required for wiring and preventing wiring mistakes.

In order to confirm the information of the connection destination at the tip of the conductive wire, it has been customary to label the conductive wire. FIG. 10 is a diagram showing a schematic configuration of a labeled conductive wire. In FIG. 10, the conductive wire 114 is crimped to the terminal member 11 by caulking the sleeve 11b, and a label 115 is provided near the sleeve 11b. By writing desired information such as the connection destination on the label 115, the information can be confirmed at the tip of the label 115.

Further, in order to confirm the information of the connection destination at the tip of the conductive wire, it has been practiced to use a terminal member which is pre-marked. FIG. 11 (a) is a diagram showing a schematic configuration of a terminal member having a pre-engraved mark, and FIG. 11 (b) is a diagram showing a schematic configuration of a conductive wire obtained by crimping the terminal member having a pre-engraved mark. Is. Figure 11
In (a), the terminal member 116 includes a connecting portion 116a and a sleeve 116b, and further, the sleeve 116.
An engraved mark 116c is provided on b. As the engraved mark 116c, a simple alphabet or number is used. Figure 11
In FIG. 11B, the conductive wire 117 presses the terminal member 116 shown in FIG. 11A by crimping the sleeve 16b. The operator who connects the conductive wire 117 has the marking 1
The connection work can be performed by determining the connection destination by 16c.

[0009]

However, in the case of labeling the conductive wires, it is necessary to label each of the conductive wires and enter or print necessary information, which is a troublesome work. There was a problem that it would be a heavy burden on the person.

Further, there is a problem that the information written or printed on the label is easily erased by rubbing or the like, and the label itself is peeled off so that the information cannot be confirmed.

Further, when a pre-engraved terminal member is used, the engraving uses simple alphabets or numbers to enhance versatility, and information corresponding to each conductive line cannot be written. There was a problem.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and provides a terminal crimping tool which reduces the operation burden on the operator and provides a sufficient information display capability to the tip of the conductive wire. With the goal.

Claims (8)

[Claims] 1. A pressure applied by a gripping operation of a predetermined lever, which is arranged in a crimping portion by covering a tip end portion of a conductive wire in which a conductor is covered with an insulator with a terminal member. A terminal crimping tool for deforming the terminal member to crimp the terminal member to the tip of the conductive wire, wherein an opening formed on the terminal member side of the crimping portion is formed with desired characters or symbols. A terminal crimping tool, characterized in that a member is mounted and a character or a symbol of the engraving member is engraved on the terminal member by a pressure associated with a gripping operation of the lever. 2. The engraving member is formed by a plurality of engraving element members respectively corresponding to different characters or symbols, and a character string or symbol engraved on the terminal member by a combination of the engraving element members. The terminal crimping tool according to claim 1, wherein rows can be selected. 3. The terminal crimping tool according to claim 2, wherein the plurality of engraving element members engrave a plurality of characters or symbols, respectively. 4. The engraving member is formed by a rotatable drum member, and a character or a symbol engraved on the terminal member can be selected by rotating the drum member. The terminal crimping tool according to 1. 5. The drum member is formed of a plurality of independently rotatable drum element members, and a character string or a symbol string engraved on the terminal member can be selected by rotating the drum element member. The terminal crimping tool according to claim 4, wherein: 6. The drum member is attachable to and detachable from the crimping section, and a character string or a symbol string engraved on the terminal member can be selected by replacing the drum member. The terminal crimping tool according to claim 4 or 5. 7. The terminal crimping tool according to claim 4, wherein the drum member or the drum element member is provided with a plurality of characters or symbols, respectively. 8. The terminal crimping tool according to claim 1, further comprising coloring means for coloring the characters or symbols engraved on the terminal member by the engraving member. .
