Description of the Related Art Conventionally, in this type of electric terminal crimping tool, a pair of crimpers for axially rotatably supporting the tip of the case and clamping the terminals by clamping the terminals at the outer ends thereof, and the crimpers are opened. An urging member for urging the link member, a link mechanism in which the other end portions of a pair of links each of which has one end portion pivotally attached to the inner end of each crimping element are pivotally attached to each other; The pressing member having a female spiral hole on the center line, and a spiral rod screwed into the female spiral hole of the pressing member and connected to a forward / reverse rotation motor driven by a battery, and the forward / reverse rotation motor. Some have a forward / reverse rotation drive and an operation switch for stopping. Some forward / reverse rotation motors are equipped with a load detector that stops when the load received from the outer end of the crimping element exceeds a predetermined value during crimping by normal rotation.

作動し押圧部材先端がリンク機構から離れるのである。When the forward / reverse rotation motor is normally rotated by the switch while the crimping element is opened by the biasing member, the spiral rod rotates on its own axis, and the pressing member screwed to the spiral rod is linked. Moving toward the mechanism, the tip of the pressing member presses the other ends (pivotally attached parts) of both links of the link mechanism. Both the pressed links act to push open the inner ends of both crimpers, and the crimpers rotate about the support shaft to close their outer ends so that the terminals can be crimped. When the forward / reverse rotation motor is reversely rotated, each member operates in the opposite manner to the above case, and the tip of the pressing member separates from the link mechanism.

Here, for example, while holding the ring-shaped terminal in one hand between the crimper outer ends, operate the switch with the other hand to rotate the forward / reverse rotation motor forward, and both crimpers lightly grasp the terminals. At that point, the forward / reverse rotation motor is stopped. Then, the tip of the electric wire is inserted into the inside of the ring-shaped terminal with the one hand, and the forward / reverse rotation motor is normally rotated to crush the terminal to crimp the terminal and the electric wire.

があった。During the above-mentioned work, it is difficult to stop the forward / reverse rotation motor so that the terminal is lightly gripped by the outer end of the crimp, and in particular, when the terminal has a plurality of sizes, It was difficult to properly handle the size of, and this work required skill. That is, when an unskilled operator operates the conventional electric terminal crimping tool,
Not only does the forward / reverse rotation motor stop too early to grasp the terminal, but on the contrary, it delays and crushes the terminal, the switch operation for grasping the terminal with the crimp is wrong, and the fingertip with the crimp is used. It had the drawback of being easily pinched and injured.

Crimper outer end 3a,
When grabbing the terminal with 3a, the biasing force of the pressing spring 11 is used instead of the electric force, so that even an inexperienced worker does not crush the terminal, and one hand holds the electric wire and the other hand. Since the hand of the operator has the manual lever 12, the operator accidentally touches the operating portion 14 of the switch mechanism to operate the forward / reverse rotation motor 7, and the fingertips are pressed against the outer ends 3a, 3a of the crimping element.
There is no danger of being injured by being caught in. Since the limit switch mechanism is provided, not only is it possible to prevent the pressing member 10 from proceeding beyond a predetermined range and to apply an unreasonable load to the forward / reverse rotation motor 7, but also to require a load detector as in the conventional example. Therefore, the manufacturing cost can be reduced.

Here, when the grip of the manual lever 12 is loosened or released, the terminal is gripped with a force that does not cause the outer ends 3a, 3a of the crimping elements to drop due to the urging force of the pressing spring 11. When the terminal is gripped in this way, an electric wire (not shown) is inserted into the terminal with one hand, and the operation portion 14 of the switch mechanism is inserted.
Slide to the tip of Case 1 and insert it into the forward rotation side. By this switching, the forward / reverse rotation motor 7 is normally rotated and the terminals are crushed, and the crimping work is completed.

ある。In this embodiment, the crimper outer ends 3a, 3a are used.
When grasping the terminal with, press the spring 11
Since the urging force of is used, even an inexperienced worker will not crush the terminal, and since one hand holds the electric wire and the other hand holds the manual lever 12,
Since the operator does not accidentally touch the operating portion 14 of the switch mechanism, there is no risk of accidental operation and the injury of being caught by the fingertips being sandwiched between the crimper outer ends 3a, 3a. Further, since the limit switch mechanism is interlocked with the movement of the pressing member 10 to prevent the pressing member 10 from moving beyond a predetermined range, the forward / reverse rotation motor 7 is not subjected to an unreasonable load, and load detection as in the conventional example is performed. There is an advantage that the manufacturing cost and the like can be reduced without requiring a container. Furthermore, since the battery is separate from the case 1, the case 1 has the advantages of being lightweight and having high operability.

ではない。In the above embodiment, the manual lever 12, which is the opening tool, is pivotally supported by the support shaft 4 of the bearing 2. However, the opening lever may be directly supported near the tip of the case 1, and the opening tool may be crimped. A structure different from that of the manual lever 12 may be used as long as the outer ends 3a, 3a can be opened. The mechanism for preventing the pressing member 10 from moving beyond the predetermined range and imposing an unreasonable load on the forward / reverse rotation motor 7 is not limited to the limit switch mechanism. The present invention is not limited to the above-described embodiments, such as providing an indicator lamp to be turned on.

効果を有する。As described above, according to the present invention, when the terminal is gripped by the crimping element, the biasing force of the manual lever and the pressing spring is used instead of the electric force. Since the switch is not crushed and the switch is not touched by mistake, there is an effect that there is no danger of being inadvertently actuated and the fingertip being caught by the outer end of the crimping device, resulting in injury.
