[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elongate type having a plurality of cylindrical sleeves for fixing and holding a metal crimp terminal having a cylindrical crimp portion for receiving an electric wire and a donut-shaped or fork-shaped flat plate portion. And a structure for mounting the insulation sleeve strip and the crimp terminal.

[0002]

2. Description of the Related Art Conventionally, as this kind of insulating sleeve band,
A large number of cylindrical sleeves connected in a parallel direction to fit and hold a cylindrical crimping portion in a longitudinal direction through a bendable connecting plate portion have been disclosed by, for example, Japanese Patent Publication No. 61-10 / 1986.
No. 948 and JP-A-6-24134.

[0003]

However, in the above-mentioned means, when the crimp terminals are held in the insulating sleeve band, the cylindrical crimp portions of the crimp terminals must be fitted into the respective cylindrical sleeves. The operation was troublesome, and it took time to remove the crimp terminal from the sleeve after inserting the electric wire into the cylindrical crimp portion of the crimp terminal and crimping the crimp portion from the outer surface of the sleeve. That is, even if the tubular sleeve portion is cut from the sleeve band at the same time as the crimping, the tubular sleeve clings to the periphery of the tubular crimping portion of the crimp terminal, and it takes time to remove it.

Accordingly, the present invention provides a crimp terminal which can be easily and reliably attached to an insulating sleeve band with a predetermined holding force, and which can be easily removed from the insulating sleeve band simultaneously with the crimping of the crimp terminal. It is a main object of the present invention to provide a mounting structure of an insulating sleeve band and a crimp terminal which can separate the crimp terminals.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the mounting structure of the long insulating sleeve strip and the crimp terminal according to the present invention, a metal crimp terminal A having a cylindrical crimp portion 4 for receiving an electric wire and a donut-shaped or fork-shaped flat plate portion 5. And a plurality of bendable connecting plate portions 2 for connecting the base portions 1 in a parallel posture and at an appropriate distance from each other by a synthetic resin material. A long insulating sleeve strip 3 which is formed by molding, a convex portion 7 for receiving the hole 6 of the flat plate portion 5 of the crimp terminal A on the upper surface of the base 1 of the insulating sleeve band 3, and a flat plate portion. An engagement pin 9 is provided for engaging the jaw 8 of the rim 5 to prevent the crimping terminal A from coming off in the axial direction of the cylindrical crimping portion 4. This is a structure in which the inner edge of the hole 6 of the flat plate portion 5 is caulked by a resultant force.

Further, in the present invention, a plurality of base portions 1 for holding a metal crimp terminal A having a cylindrical crimp portion 4 for receiving an electric wire and a donut-shaped or fork-shaped flat plate portion 5 are provided.
And a bendable connecting plate portion 2 for connecting these base portions 1 in a parallel posture and at an appropriate distance from each other, and a long insulating sleeve band integrally molded with a synthetic resin material. 3, a concave portion 7 'for receiving the flat plate portion 5 of the crimp terminal A is formed on the upper surface of the base portion 1 of the insulating sleeve band 3 along the outer contour of the flat plate portion 5, and the concave portion 7' Is characterized in that at least a part of the outer edge of the crimp terminal A is caulked to the outer peripheral edge of the flat plate portion 5 of the crimp terminal A with a predetermined engaging force.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 6 show a first embodiment of the present invention, for holding a metal crimp terminal A having a cylindrical crimp portion 4 for receiving an electric wire and a donut-shaped flat plate portion 5. A plurality of base portions 1 and a bendable connecting plate portion 2 for connecting the base portions 1 in a parallel posture and at an appropriate distance from each other are integrally molded with a synthetic resin material. A long insulating sleeve strip 3 is provided.

A cylindrical projection 7 for receiving the hole 6 of the flat plate portion 5 of the crimp terminal A on the upper surface of the base 1 of the insulating sleeve band 3 and a jaw 8 of the flat plate portion 5 of the crimp terminal A are engaged. An engagement pin 9 is provided to prevent the crimp terminal A from coming off in the axial direction (arrow direction) of the cylindrical crimp portion 4. The upper edge of the convex portion 7 is caulked to the inner edge of the hole 6 of the flat plate portion 5 with a predetermined engaging force. The predetermined engagement force is
When the insulating sleeve band 3 holding the crimp terminal A is wound up in a reel shape or loaded in a crimping device to perform a crimping operation, the crimp terminal can be reliably held without falling off the insulating sleeve band. However, it is an engaging force enough to press down the upper surface of the convex portion 7 with a push rod 13 described below to remove the crimped portion and to separate the crimp terminal A.

When the crimp terminal A is mounted on the base 1 of the insulating sleeve strip 3, the hole 6 of the flat plate portion 5 of the crimp terminal A is inserted into the projection 7 of the base 1, as shown in FIGS. Thereafter, the upper end of the convex portion 7 is slightly pressed with the heated caulking bar 10 and caulked, whereby the projection 7 can be easily attached.

The back surface of the base 1 is preferably formed by cutting off the thickness as shown in FIGS. 3 to 6 in order to reduce the material and prevent deformation due to shrinkage during molding. The flexible connecting plate 2 is not limited to the two parallel strips shown in the above embodiment, but may be a cross or a single thin plate.

As shown in FIG. 7, the crimp terminal A attached to the insulating sleeve band 3 may have a plate-like portion 7 'formed in a fork shape. In this case, the upper end edge of the convex portion 7 is caulked in the hole 6 'opened toward the front end.

For the crimp terminal A attached to the insulating sleeve band 3 as described above, for example, as shown in FIG. Then, the electric wires are connected by crimping with the crimping tools 11, 11. At this time, if the push rod 13 is fixed to the upper crimping tool 11 in a parallel posture, the protrusion 7
Is pressed, the crimped portion is released, and the crimp terminal A can be separated from the insulating sleeve band 3.

FIG. 10 shows another embodiment of the present invention. In this embodiment, the base portion 1 is replaced with the projection 7.
A concave portion 7 'for receiving the flat plate portion 5 of the crimp terminal A is provided on an upper surface of the crimp terminal A. The concave portion 7 ′ is formed along the outer contour of the flat plate portion 5. A protruding portion 12 for caulking is provided at a part of the outer edge of the concave portion 7 ′. The outer peripheral edge of the flat plate portion 5 is caulked with the predetermined engagement force. As in the first embodiment, when the insulating sleeve band 3 is carried or loaded into the crimping device, the crimp terminal does not fall out of the insulating sleeve band during its operation as in the first embodiment. .

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to these embodiments. For example, in the embodiment shown in FIG. 12, several caulking portions may be provided or may be formed over the entire circumference of the concave portion 7 '.
In addition, the present invention can be appropriately modified and implemented as long as it has the constituent elements, achieves the above-described object, and has the following effects.

[0015]

According to the present invention, since the mounting structure of the long insulating sleeve band and the crimp terminal is constructed as described above, the crimp terminal can be easily and reliably mounted on the insulating sleeve band with a predetermined holding force. It is possible to prevent the crimping terminal from dropping off the insulating sleeve band during its operation when the insulating sleeve band is wound up in a loop or when the crimping device is loaded on the crimping device. Providing a simple push rod has a remarkable effect that the crimp terminal can be separated from the insulating sleeve band at the same time as the crimp terminal is crimped.
