DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crimping die structure for crimping a crimp terminal to a wire end and a waterproof plug at a time while a waterproof plug having a wire insertion hole is fitted to the end of the wire. .

[0002]

2. Description of the Related Art Generally, a waterproof connector terminal has a structure as shown in FIG.
Rubber stoppers 1A and 1B shown in FIGS. 1 and 12 are used in the state shown in FIG. That is, the rubber stoppers 1A, 1B
Has a base 6 in the first half, a bulge 5 in the second half, and a center hole 4 passing therethrough.
A and 1B are fitted to the electric wire 2 and the terminal 3 is crimped to the base 6 to manufacture the waterproof connector terminal. Then, the waterproof connector terminal is inserted into the terminal receiving hole of the waterproof connector. And attach it. In the mounted state, the bulging portion 5 is pressed against the peripheral wall of the terminal accommodating chamber,
Thereby, waterproofing is achieved.

[0003] In recent years, a manufacturing apparatus for automating the manufacturing of the above-described waterproof connector terminal has been tried. In general, the process of this manufacturing apparatus includes a cutting step of cutting the covered electric wire W to a predetermined length (see FIG. 14A), and a rubber plug 1A at an end Wa of the cut electric wire W. A rubber plug insertion step of fitting with the insertion tool G (see FIGS. 14B and 14C),
A stripping step of stripping the coating of the end Wa of the electric wire W by the stripping blade C (see FIGS. 14D and 14E), and the electric wire stripped by the fixed lower die LD and the movable upper die UD. A terminal crimping step (see FIGS. 14F and 14G) of crimping the crimp terminal T together with the rubber plug 1A to the end Wa of W is included.

[0004]

However, there have been cases where the rubber plug attached to the electric wire supplied to the terminal crimping step is displaced in the longitudinal direction of the electric wire. In this case, the crimp terminal cannot be crimped to the rubber stopper, or the rubber stopper is crimped in a displaced state.

[0005] Originally, rubber stoppers tended to be easily displaced with respect to the electric wire for the following reasons, which contributed to the above-mentioned problem. That is, a) In order to reduce the cost by sharing, one type of rubber plug is usually adapted to a plurality of types of electric wires having different thickness sizes (outer diameter sizes of the covering portion). Therefore, the connection between the waterproof plug and the electric wire may be relatively loose, and
b) The rubber plug contains a lubricating oil such as silicone oil for facilitating insertion into the connector. For the reasons a) and b), the rubber plug tends to slide on the electric wire. As a result, the rubber stopper tends to be displaced with respect to the electric wire.

Also, since an elastic rubber plug tends to escape when compressed during crimping, if the rubber plug is supplied to the terminal crimping step with the rubber plug mounted at an appropriate position with respect to the electric wire, Even in such a case, the rubber stopper sometimes shifts in the longitudinal direction of the electric wire (in the direction away from the crimp terminal) during crimping. On the other hand, instead of the above-mentioned automated process, in the case of a manual process of crimping by holding an electric wire by hand,
In some cases, the rubber stopper has come into contact with something, resulting in displacement, which has the same problem as in the case of the automation process.

Next, the operation in the terminal crimping step will be described in detail with reference to FIGS. As shown in FIG. 15A, the electric wire W has an end W
A portion Wb that is a predetermined distance from the chucking arm CA [for example, provided on the circumference of a rotary transfer section (turntable) as shown in FIG. 11 of Japanese Patent Publication No. 3-5029). ]. Then, with the rotation of the rotary transfer unit, the end Wa of the electric wire
Is transported and positioned at a predetermined height between the fixed mold LD and the movable mold UD.

Next, the movable UD descends due to terminal crimping. As shown in FIG. 15B, when the movable UD reaches the bottom dead center, the end Wa of the electric wire is moved to the movable mold UD. Due to the UD, it is pushed down by a predetermined amount from the height as shown in FIG. Therefore, the height of the end portion Wa of the electric wire W becomes lower than the height of the sandwiched portion Wb. As a result, FIG.
(C) As shown in FIG.
The crimping has been performed with a predetermined angle θ (eg, θ = 10 °).

As shown in FIG. 16, the waterproof connector terminal having the crimp terminal T inclined with respect to the electric wire W and the rubber plug 1A is inserted into the terminal receiving hole H1 formed in the housing H of the waterproof connector WPC as shown in FIG. If you try, rubber stopper 1A
Bulge 5 is hooked on the peripheral portion of the terminal receiving hole H1,
As a result, there were cases where the rubber plug 1A could not be inserted or the rubber stopper 1A came off the crimp terminal T. Also, the core wire sometimes protruded from the crimp terminal. In order to avoid these problems, it is necessary to correct the inclination after crimping, which is troublesome.

Accordingly, a first object of the present invention is to provide a crimping die structure capable of preventing poor crimping due to escape of a waterproof plug during crimping. A second object of the present invention is to provide a crimping die structure that can prevent a crimping terminal from being crimped in an inclined state with respect to a waterproof plug. A third object of the present invention is to provide a crimping die structure capable of correcting a displacement of a waterproof plug with respect to an electric wire during crimping.

In order to achieve the first object, the crimping die structure according to the first aspect comprises a fixed type on which the crimping terminal is set, and a plurality of crimping terminals connected in a chain by a band-like connecting portion.

The end W2 of the wire W into which the rubber stopper 1A has been fitted and which has been peeled off is, for example, on the circumference of a rotary transfer section (turntable) as shown in FIG. 11 of Japanese Patent Publication No. 3-5029. The provided chucking arm (corresponding to the arm CA in FIG. 1 of this embodiment) is transported by being rotated while holding a portion W3 of a predetermined distance from the end W2 of the electric wire W, and is transferred to the final crimping metal. It is designed to be positioned at a predetermined position between the anvil 12 and the crimper 13 having the mold structure. On the other hand, at a predetermined position on the anvil 12, a large number of crimp terminals T connected in a chain in a direction perpendicular to the paper surface by a connection portion Tc are intermittently arranged one by one in accordance with supply of one electric wire W. It is designed to be sent.

At the upper end of the cutter holder CH, a stopper CH1 for positioning the upper stop position of the slide cutter 16 by contacting the engagement protrusion 16d of the slide cutter 16 is formed.

The upper surface 16a of the slide cutter 16 is provided with a recess 16e for accommodating a part of the bulge 5 of the rubber plug 1A. A pair of surfaces 16f and 16g that define the housing recess 16e and receive the end surface of the rubber plug 1A.
Are perpendicular to the longitudinal direction of the electric wire and are parallel to each other. The bottom surface 16h of the housing recess 16e is formed in a curved surface that can substantially follow the outer peripheral surface of the bulging portion 5 of the rubber plug 1A.

On the end face of the slide cutter 16 on the anvil side, the connection portion Tc of the crimp terminal T placed on the anvil 12 (the crimp terminals are formed in a belt shape) with the slide cutter 16 positioned at the upper stop position. Part to connect)
Is formed, and a concave portion 16b for holding this is formed. That is, when the slide cutter 16 is positioned at the upper stop position, as shown in FIG.
The height of b is such that the connection portion Tc of the crimp terminal T placed on the anvil 12 can be just introduced.

Referring to FIG. 2, the upper surface 16a of the slide cutter 16 is pressed by the pressing protrusion 141 (see FIG. 2) at the lower end edge of the crimper holding portion 14A which is lowered at the time of caulking, so that the slide cutter 16 is pressed. 16 descends while compressing the compression coil spring 17,
The connection portion Tc of the crimp terminal T introduced into the recess 16b is cut by shearing.

Referring to FIGS. 1 and 2, crimper holding portion 14A is provided with crimper 13 and crimper holding portion 14 by bolts B inserted into a pair of screw insertion holes 143.

And a lower end flange portion 18b formed with an accommodating concave portion 18c capable of accommodating a part of the above. The shape of the housing recess 18c is substantially the same as the shape of the housing recess 16e of the slide cutter 16, and the surfaces 18f and 18g correspond to the surfaces 16f and 16g, respectively, and the bottom surface 18h corresponds to the bottom surface 16h. The surfaces 16f and 18f prevent the rubber plug 1A from escaping in a direction away from the crimp terminal T (X direction in the figure). In addition, the surfaces 16g and 18g prevent the rubber plug 1A from escaping in the direction closer to the crimp terminal T (the direction opposite to the X direction in the figure).

The main body 18a is introduced into a vertical groove 142 formed in the crimper holding portion 14A.
A compression coil spring 19 that elastically urges the contact member 18 downward is interposed between the upper surface d of a and the upper frame 11.
