Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a printing crimping tool for electric wires (cable cores), and in particular, a printing crimping tool that can attach terminal distinguishing symbols at the same time as terminal crimping. Regarding.

[Conventional technology and its issues]

Control cables and signal cables extending from measurement and control points are concentrated behind the control panel. It is extremely important to connect each core wire of these extended cables to the terminal board of the control panel without fail, and if this is done incorrectly, it may lead to a serious accident.

For this reason, especially for large control panels where many cables are connected, when crimping a terminal to each core wire of the cable, a distinguishing symbol (terminal number, etc.) is written on the tag or insulation tube of the terminal. I am trying to add .

However, the work of adding this symbol is quite troublesome and takes a lot of time.

Therefore, in view of the above, an object of the present invention is to provide a symbol for distinguishing the terminal at the same time as the crimping when the terminal is crimped to the electric wire such as the cable core.

[Means for solving problems]

In order to solve the above problems, in this invention,
The anvil-side lever and the press-side lever are rotatably connected via a pin in the middle, and the rear end of the anvil-side lever is extended to form an anvil-side grip, and the rear end of the press-side lever is extended. A press side grip is rotatably connected to the press side grip, and a side of the press side grip rearward from the connection point is connected to the anvil side grip by a rotating link,
At the tip of the press side lever, a terminal crimping fitting and a printing device are arranged side by side so that their crimping surfaces are coaxial, and at the tip of the anvil side lever,
The structure is such that an anvil for a crimping fitting and an anvil for a printing device are respectively provided, which face each other with the electric wire and its terminal interposed therebetween.

The above-mentioned printing device may be of any type as long as it is capable of marking a symbol indicating the type, such as numbers, Roman letters, katakana, etc., and various methods such as a stamp type, a stamp type, etc., can be used as the marking device.

[Effect]

The printing crimping tool configured in this way inserts the terminal into the end of the electric wire, inserts it between the crimping fitting and the crimping surface of the printing device, and the anvil with the tips of both levers open, and presses both grips. When you tighten your grip,
The rotating link increases the gripping force and transmits it to the tip of the lever, and the crimping fitting and its anvil crimp the terminal to the wire, and the marking device and its anvil stamp the symbol on the terminal or wire coating. will be attached.

If a tube is placed over the end of the wire in advance and the terminal is crimped through the tube, a symbol can be attached to the tube.

〔Example〕

As shown in FIG. 1, the anvil-side lever 1 and the press-side lever 2 are each made up of two plates integrated with a gap between them, and are rotatably connected via a pin 3 in the middle. The rear end of the anvil-side lever 1 is extended to form an anvil-side grip 4 covered with a synthetic resin cover 4a. A synthetic resin cover 5a is provided at the rear end of the press side lever 2.
The press-side grip 5 covered with
The rear side and the anvil side grip 4 are connected by a rotating link 7, and both grips 4, 5
When the grip is tightened, the grip force is increased through the link 7 and transmitted to the tips of both levers 1 and 2.

A ratchet 8 is formed on the link 7, and a rotary pawl 9 is urged by a spring 10 to be able to engage with the ratchet 8, and as shown in FIG. 2a, both grips 4 and 5 are opened. In the state,
When the pawl 9 comes off the ratchet 8 and grips the grips 4 and 5 from this state, the pawl 9 engages with the ratchet 8 and moves both grips 4 and 5 in the opening direction, as shown in FIG. The opening is prevented (the opening operation involves turning the pawl 9 as indicated by the arrow in Figure b, and the pawl 9 bites into the ratchet 8 and cannot rotate any further). Therefore, you can re-tighten it by changing your grip. When both grips 4 and 5 are fully grasped and the pawl 9 comes off the latch 8 as shown in FIG. The grips 4 and 5 open while slidingly contacting each other. This opening is done by link 7 and anvil lever 1.
This is done by the spring 11 between the two, and at that time, there is no problem because the claw 9 can rotate as shown by the arrow c in the same figure.

At the tip of the press side lever 2, a terminal crimping fitting 12 and a printing device 13 are arranged side by side with their crimping surfaces coaxially aligned, and at the tip of the anvil side lever 1, an electric wire P and its terminal a are interposed. An anvil 14 for the crimping fitting and an anvil 15 for the printing device are respectively provided which face each other. and press the tips of both levers 1 and 2,
Terminal a is crimped to the terminal of electric wire P, and a symbol is attached to it.

The printing device 13 has the same structure as an office device commonly called a number ring, and as shown in FIG. 17a, 17b, 17c (generic code: 17) are provided in the casing 18 so as to be articulated and rotatable, and side ratchets 19a, 19b, 19c (generic code: 19) of each ring 17 are connected to claws 20a, 20b, 20c. (Generic code: 20) is rotated by one character by vertical movement, thereby changing the characters facing the anvils 14, 15 one after another. The engraved “3” on the ratchets 19a and 19b
The portion 19a' corresponding to 19a' has a deeper trough than the others, and when the claws 20a and 20b enter the trough (at this time, the inscription "f" faces the anvil 15), for example. , the claw 20a is the ratchet 1
When the pawl 20b enters the trough 19a' of the ratchet 9a, the pawl 20b engages with the peak of the ratchet 19b, and as the pawl 20 moves up and down, the rings 17a and 17b rotate. Not only the pawl 20b but also the pawl 20c engage with the crest of the ratchet 19c, and as the pawl 20 moves up and down, the rings 17a, 17b, and 17c rotate. Therefore, one vertical movement of the claw 20 rotates the ring 17a by one character, one rotation of the ring 17a rotates the ring 17b by one character, and one rotation of the ring 17b rotates the ring 17a by one character. 17c rotates by one character.

The pawl 20 is rotatably attached to a rotating plate 21 of the casing 18, and is biased toward the ratchet 19 by a spring 22'. Rotating plate 2
1 includes a vertically movable rod 2 supported by a casing 18.
2 is attached so as to be swingable, and is biased counterclockwise (in the direction of the arrow) in FIG. The rotating plate 21 is moved upward in contact with the rotating plate 21, and as a result of this movement, the rotating plate 21 rotates clockwise in FIG. 3 against the force of the spring 23. When levers 1 and 2 open, spring 23
As a result, the rotating plate 21 is rotated in the reverse direction, and as the rotating plate 21 rotates, the pawl 20 rotates the ring 17 via the ratchet 19 (see FIG. 5). That is, the next inscription is made to face the anvil 15. For example, if the characters currently engraved are 1, 2, and 2, only the ring 17a is rotated to make the characters 1, 2, and 3 face each other.

In the figure, reference numeral 24 is a leaf spring that is brought into pressure contact with the ring 17, and this leaf spring 24 prevents the ring 17 from moving inadvertently.

This embodiment is configured as described above,
As shown in FIG. 6a, insert tube b and terminal a into the end of electric wire P,
With the tip of 2 open, insert it between the crimping fitting 12 and printing device 13 and anvils 14 and 15 (crimping groove 16), and grip both grips 4 and 5.The rotating link 7 increases the gripping force. As shown in FIG. “123” is engraved on b.

When the electric wire P is removed and applied in the same manner, the terminal a is crimped and the tube b has a "124"
is engraved.

By repeating this action, the terminal a is crimped onto the electric wire P, and markings for distinguishing each terminal are attached.

In addition, the crimp groove 16 according to the diameter of the electric wire P, for example,
1.25mm, 2.0mm... crimp groove on anvil 14,
15 may be arranged in the front-rear direction, and the printing device 13 may be movable and fixed so as to correspond to each groove.

[Effect of idea]

Since the present invention is configured as described above, terminal crimping and terminal distinguishing symbols can be performed at the same time, and the work efficiency is significantly improved.
