Abstract

PURPOSE:To prevent the damage of the coat of an electric wire and improve the quality of a terminal by forming the radius of the curved surface of one corner part of a barrel guide caulking groove smaller than the radius of the residual corner part, and making the part continued to both the corner parts into a flat surface. CONSTITUTION:When the insulation barrel A2 of an electric wire terminal is overlapped and wound on the coat of an electric wire (a), the insulation barrel A2 s pushed into the barrel guide caulking groove 21 of a second crimper 20, and a curved surface having a small radius is formed by one corner part 21a having the upper end part formed with a small radius and wound on the coat of the wire (a). A curved surface having a large radius is formed by the other corner part 21b having the upper end part formed with a large radius, and overlapped and wound on the coat of the wire (a). Thus, it is never caused that the thin coat of the wire (a) is broken by the insulation barrel A2 to loose the function as an insulator, and the quality of a cable terminal can be improved.

As shown in FIG. 3, the terminal body A made of a conductive material is formed by cutting and erecting the wire barrel A1 and a pair of insulation barrels A2. And the insulation barrels A2 are crimped to the end portions of the electric wires a.

On the other hand, a cable formed by bundling a plurality of electric wires a is used, for example, in wiring of an automobile, but the outer diameter of the cable is in the pipe despite the increase in the number of electric wires a used. Since it is difficult to make the cable thicker than the above because it is installed by pulling it in, it is becoming popular to use a cable in which the thickness of the wire a covered is thin.

A caulking device for an electric wire terminal in an electric wire processing machine of this type that has been already proposed is constructed as shown in FIGS. 4 to 6.

That is, in FIGS. 4 to 6, an anvil member 2 is installed on a machine frame 1 of an electric wire processing machine, and the anvil member 2 has a first anvil 3 as a wire anvil and an installation. A second anvil 4 as an anvil is provided in order, and a slide cutter 6 whose floating position is restricted by a cut holder 5 is urged upward by the elastic force of a pair of coil springs 7 on the front surface of the second anvil 4. It is installed so that it can be raised and lowered. A guide groove 6a for guiding the leader portion A3 and a cutter portion 6b guide the leader portion A3 of the terminal body A on the upper part of the slide cutter 6, and at the time of caulking operation, the terminal body A and the leader portion A3. It is designed to disconnect and. Further, the anvil member 2, the first anvil 3, the second anvil 4 and the slide cutter 6 constitute a lower die of the electric wire processing machine.

On the other hand, on the upper part of the upper machine frame 1 of the lower die, an elevating body 8 composed of a shank 8a and a spacer 8b is provided so as to move up and down by a crank mechanism (not shown). A first crimper 9 as a wire crimper and a second crimper 10 as an insulation crimper are attached to the front surface of the lifting body 8 so as to operate in cooperation with the first anvil 3 and the second anvil 4.

That is, in the lower portion of the first crimper 9, a centering groove 9a having a substantially inverted V shape is cooperated with the upper portion 3a of the first anvil 3 to crimp each wire barrel A1 of the terminal body A. At the lower portion of the second crimper 10, a centering groove 10a having a substantially inverted V shape is formed in cooperation with the upper portion 4a of the second anvil 4 and each insole of the terminal main body A is attached. It is formed so as to crimp the ration barrel A2. In addition, the lifting body 8
A cut-off punch 11 is screwed on the front surface of the first and second crimper 9 and 10 by means of a tightening screw rod 12.
The second crimper 10, the cut-off punch 11, and the tightening screw 12 constitute an upper die of the electric wire processing machine.

Therefore, the caulking device for the electric wire terminal in the electric wire processing machine described above is, as shown in FIG.
The terminal body A and the leader portion A3 are placed and placed on the lower slide cutter 6.

Next, the upper end of the lower die slide cutter 6 is transferred, for example, with one end (strip portion) a1 of the electric wire a being held by a clamp device 13 or a centering holding tool 14 provided on an index table. And stop. Then, since the upper die lifting body 8 descends by a crank mechanism (not shown), the centering groove 9a of the first crimper 9 cooperates with the upper portion 3a of the first anvil 3 to form each wire barrel of the terminal body A. When A1 is caulked, at the same time, the centering groove 1 of the second crimper 10 is
0a cooperates with the upper portion 4a of the second anvil 4 to crimp the respective insulation barrels A2 of the terminal body A, and the punch portion 11 of the cutoff punch 11
When the slide cutter 6 is pressed with a, the cutter portion 6b of the slide cutter 6 cuts the leader portion A3 of the terminal body A in cooperation with the second anvil 4.

[0010]

However, the caulking device for the electric wire terminal in the electric wire processing machine described above is shown in FIG.
As shown in FIG. 6, the centering groove 10a of the second crimper 10 cooperates with the upper portion 4a of the second anvil 4 to install the insulation barrel A2 of the terminal body A.
Since the upper ends of the insulation barrels A2 are caulked by being caulked from above into the sheath of the electric wire a due to the caulking, the electric wire with a thin wall thickness of the sheath is used for the upper ends of the insulation barrel A2. It is broken by
Not only does it lose its function as an insulator by contacting 1
The quality of the wire terminals is impaired and, in addition, many wires of this kind already on the market are wasted.

On the other hand, since the above-mentioned wire terminal molds are not compatible with each other, it is difficult to change them easily. There is a problem in that the cost will increase if it is prepared.

The present invention has been made in view of the above-mentioned circumstances, and an electric wire in which the insulation barrel of the terminal is overlapped and wound around the electric wire coating and crimped to form a thin coating wall thickness. Even if it is, the quality of the wire terminals is improved by not breaking the upper end of the insulation barrel and contacting the core wire and impairing the function as an insulator. An object of the present invention is to provide a caulking device for an electric wire terminal, which does not require a new mold for matching terminals.

[0013]

According to the present invention, a first anvil and a second anvil are sequentially provided on an anvil member of a machine frame, and a first crimper and a second crimper are provided on the machine frame directly above both anvils. In an electric wire processing machine that is vertically movable so as to operate in cooperation with an anvil, a barrel guide caulking groove is formed in the lower part of the second crimper, and the center of the barrel guiding caulking groove is set as a virtual center of both the anvils. The radius of the curved surface of one corner portion of the barrel guide caulking groove on the biased side is made smaller than the radius of the remaining corner portion, and the portion connecting to both corner portions is formed. It is formed on a smooth surface.

[0014]

According to the present invention, when the insulation barrel of the terminal is wrapped around the electric wire coating and crimped, the one insulation barrel is pushed into the barrel guide crimping groove of the second crimper while pushing the insulation barrel. The upper end of the wire is wrapped around the wire by forming a curved surface with a small radius at the corner with a small radius, while the other end of the insulation barrel has a large radius at the corner with a large radius. The curved surface of the wire is formed so that it overlaps with the coating of the electric wire and is wound and crimped so that the function as an insulator is not impaired and the quality of the electric wire terminal is improved.
