[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire connecting structure for connecting electric wires using a crimping piece connected to a connecting piece via a bridge portion.

[0002]

2. Description of the Related Art Conventionally, when a branch wire is connected to a main electric wire, a crimp terminal 1 as shown in FIG. 3 is sometimes used. This crimp terminal 1 is composed of a plurality of crimping pieces 2 and one connecting piece 3.
For example, first, as shown in FIG. 4, a core portion 5 a of a branch 5 is disposed in the crimping piece 2. At this time, the distal end portion 5b is visually positioned, and the core wire 6a of the main line 6 is superimposed on the core wire 5a of the branch wire 5 arranged in the crimping piece 2, and then the crimping piece 2 is bent by a crimping mechanism (not shown). Then, the core wires 5a and 6a are crimped and connected, and the crimping piece 2 is cut from the bridging portion 4 at the cutting portion 2a by a cutting mechanism. In this manner, the core wires 5a and 6a connected via the crimping pieces 2 are wound with an insulating tape or the like and subjected to an insulation protection process.

[0003]

However, in the above-mentioned conventional example, since the core wire 5a of the branch wire 5 is positioned visually in the crimping piece 2, the operation requires skill. When the core wire 5a of the branch wire 5 is positioned so as to protrude too much as shown in FIG. 4, a part of the tip 5b of the core wire 5a made of a stranded wire is bent outward to break the insulating tape to be covered. This may cause a short circuit.

An object of the present invention is to solve the above-mentioned problems and to provide an electric wire connection structure in which a terminal portion of a core wire is prevented from being bent.

[0005]

According to the present invention, there is provided an electric wire connection structure for achieving the above-mentioned object, in which a crimping piece connected to a connecting piece via a band-like bridging portion is used to expose an exposed core wire. in the electric wire connection structure that connects the core of the branch line to the
By separating the bridging portion and the connecting piece, the connecting piece
Said crimping piece separated from the core of the branch line whose tip is placed on a piece the crimp to reach on the bridging portion, said branch lines the crimping piece overlaid on the core of the branch line by caulking Core
And a core wire of the main wire crimped and connected.

[0006]

In the electric wire connection structure having the above configuration,
When connecting the two core wires, the bridging portion of the crimping piece supports the tip of the core wire of the branch wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is an explanatory view of an apparatus for realizing the electric wire connection structure of the present invention. The crimping terminals 11 are manufactured in a state where the crimping pieces 12 are individually connected to the connecting pieces 13 via the band-shaped bridging portions 14 having a length D, and the crimping pieces 12 are sequentially conveyed onto the lower press die 15. It has become. Above the lower press die 15, an upper press die 16 which cooperates with the lower press die 15 and bends the crimping piece 12 is movably disposed. A slide cutter 17 for cutting between the parts 14 is installed so as to be slidable in the vertical direction. Slide cutter 1
A groove 17a for fitting the connecting piece 13 is provided on the side of the lower press die 15 on the side surface of the groove 7;
A regulating surface 17b for regulating the position of the distal end of the core wire 18a of the branch wire 18 disposed therein is provided. Further, on the upper surface of the slide cutter 17, a mounting surface 17c on which a main line 19 to be superimposed on the branch line 18 is mounted.

With such a configuration, when the core wire 18a of the branch wire 18 and the exposed core wire 19a of the main wire 19 are connected via the crimping piece 12 using the crimping terminal 11, the connecting piece 1
The crimping piece 12 is conveyed onto the lower press die 15 in a state where 3 is positioned in the groove 17a of the slide cutter 17,
The tip 18 of the core wire 18 a of the branch wire 18 is provided in the crimping piece 12.
b is arranged so as to abut the regulating surface 17 b of the slide cutter 17. On the core wire 18a of the branch wire 18, the core wire 19a of the main wire 19 is placed on the mounting surface 17c of the slide cutter 17.
The upper press die 16
Is lowered, the crimping piece 12 is bent, and the core wires 18a, 19a are bent.
Compression bonding is performed by caulking.

At the same time or before and after the slide cutter 17,
Is lowered, and the bridging portion 14 is cut by the cutting portion 14 a at a position near the connecting piece 13. At this time, the bridge portion 14 having the length D is left below the core wire 18a of the branch wire 18.

[0010]

As described above, the electric wire connection structure according to the present invention prevents the tip of the core wire from projecting by placing the tip of the core wire of the branch wire on the bridge portion.
