Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in circuit wires with connector terminals used, for example, as automotive wires.

Generally, the wires in an automobile wire system are color-coded for the purpose of distinguishing them from each other.

This color classification is usually done by applying color-coded bands extending like stripes on the ground color of the insulator.

This color classification is achieved not by color printing on the insulators, but by supplying resins of different colors (ground color and identification color) to an extruder and extruding these different colored resins onto the conductor. It is being done.

However, since there are about 100 circuits in an automobile wiring harness, several dozen types of wires must be prepared in order to color-code the circuit wires for each circuit.

Therefore, the material in the extruder has to be replaced for each different circuit wire, and since the length of the wire manufactured differs depending on the color, inspection is troublesome, making process control complicated. Therefore, inventory management was troublesome.

An object of the present invention is to provide a circuit wire with a connector terminal that is easy to manufacture and manage without having to be color-coded by the insulator itself.

The embodiments of the present invention will be described in detail with reference to the drawings.
Figures 1 and 2 respectively show a circuit wire 10 with a connector terminal according to the present invention, in which the insulated wire 12 is separated from the conductor 14 and the monochrome insulator 16 extruded thereon, and the connector terminal 18 is insulated. Conductor 1 exposed at the end of wire 12
The connector main body 24 has a first crimp holding part 20 which is crimped to the insulator 16 and a second crimp holding part 22 which is crimped to the insulator 16.

The connector terminal 18 is attached to the insulated wire 12 by being crimped to the conductor 14 and the insulator 16 using these first and second crimp holding parts.

As shown in the east figure, the circuit wire 10 with a connector terminal of the present invention is further provided with a colored piece 26 which is crimped together with the insulator 16 of the insulated wire 12 on the second crimp holding portion 22 of the connector terminal 18.

The colored piece 26 is crimped at the same time as the connector terminal 18 is crimped, for example, by feeding out a colored tape from a colored tape roll installed in a terminal crimping machine and cutting it into a predetermined length.

The colored piece 26 is preferably made of a material that is semi-hard and has high wear resistance and tensile strength, such as vinyl chloride,
Examples include polypropylene and nylon.

In the embodiment of FIGS. 1 and 2, the colored piece 26 is cut from a tape section formed by cutting a colored tape as described above, and in the embodiment of FIG. 1, this tape section is cut from an insulated wire. In the embodiment shown in FIG. 2, the tape sections are provided so as to be wound along the circumferential surface of the insulated wire 120.

Length l of the colored piece 26 protruding from the second crimp holding part 22
(See FIG. 2) must be sufficiently recognizable from the outside when the connector terminal 18 is attached to a connector housing (not shown).

An automobile wire harness is formed by bundling a large number of circuit wires 10 with connector terminals and wrapping most of the wire length with tape.

After assembly, since the part near the connector terminal 18 is not wrapped with tape, the colored piece 26 is exposed and the circuit wire 12
can be identified.

According to the present invention, as described above, since the colored piece is crimped together with the insulated wire by the connector terminal that is crimped and connected to the insulated wire, there is no need to color the insulated wire itself. A single color simplifies the wire manufacturing process and inventory management, and since the colored piece is crimped onto a somewhat elastic insulator rather than onto a conductor, it can be easily cut at the edge of the crimping holding part. It is possible to reliably identify circuit wires without any problems.
