Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape with a different type of terminal and a terminal crimping machine for manufacturing an electric wire with a terminal which constitutes an assembled electric wire (wire harness) for an automobile.

[0002]

2. Description of the Related Art A wire harness is generally composed of a large number of electric wires W.
7 is provided with a tape or the like, and as shown in FIG. 7, a plurality of branch line portions W ₁ , W _2, ... Are provided for the main line portion W ₀ , and connectors c ₁ , c ₂ ... Is provided.

The wire harness W is roughly classified into a batch method and a set method. In the batch method, a fixed-length electric wire in which connector terminals are crimped to both ends of an electric wire cut into a predetermined length is individually produced in lots, and these are arranged two-dimensionally on a wiring board (not shown) as shown in FIG. The terminal of the terminal is inserted into the connector (housing).
As shown in FIG. 9, the set method is as follows. _First , all the wires w ₁ , w ₂ ... Which compose the wire harness W are bent in a U shape, and both ends are locked to the wire clips 52 arranged in parallel in the wire clamp tool 51. By doing so, the end portions of the electric wires are aligned on one side and arranged at equal pitches to form one harness set P ₁ .

This harness set P ₁ is provided with a terminal processing table 5
3 is intermittently fed in the direction of the arrow, and the electric wires are sequentially bent by the electric wire straightening device 54 so that the peeling device 55
After peeling off the insulating coating on the ends with a terminal crimping machine 56
_The desired terminal is crimped with any one of ₁ , 56 ₂ ... 56 _n . In the figure, reference numeral 57 denotes a composite head, which is provided with a pair of openable and closable electric wire clamp plates 58 and moves in parallel with the terminal processing table 53 to transfer or superpose the locked electric wires.

The wire harness W of FIG. 7 has an appearance similar to that of a vehicle, but it is grouped into branch lines W ₁ , W ₂ ... By connectors c ₁ , c ₂ ... As shown in FIG. 8, by using one wire clamp 51, the connector c ₁ , c ₂ ... Group or the ends of the wires can be aligned on one side, and further, the connectors c ₁ , c By removing the group ₂ ... and returning the group of electric wires w ₁ , w ₂ to the original locking position by the composite head 57, the state as shown in FIG. 10 can be easily restored. The set method was developed by focusing on these facts. In the figure, w ₀ indicates an electric wire in which a plurality (mostly two) of electric wires w are superposed for double crimping to one terminal.

[0006]

In the wire harness set type manufacturing method, the terminals 59 ₁ , 59 ₂ ... Group are crimped to the terminals of the wires w ₁ , w ₂ ... Group in FIG. It is necessary to equip a large number of terminal crimping machines 56 ₁ , 56 ₂ ... because the number reaches a considerable number due to the difference between female and male, shape and size, and the number increases as the scale of the wire harness increases. , Has a large space for mounting.

Further, the terminal crimping machines 56 ₁ , 56 ₂ ...
A so-called vertical chain terminal reel 59 'as shown in FIG.
In this case, the reel 59 'can be installed behind the terminal crimping machine 56 _{1 and the} like. However, in the case of using the laterally chained terminal 60 as shown in FIG. 11A, the side of the anvil 61 and the crimper 62 which is moved up and down by the ram 63 in the terminal crimping machine 56 ₁ ′ as shown in FIG. 11B. Since the terminal feeding device 64 must be installed in the terminal crimping machine 56 ₁ ′, the installation space for each terminal crimping machine 56 ₁ ′ becomes large. Therefore, not only is the terminal processing table 53 increased in size, but dedicated terminal crimping machines 56 ₁ , 56 ₂ ... 56 ₁ ′ are required for each type of terminal.
There is a problem that the device cost increases. In the figure, 65 is a terminal carrier, 65a is a terminal feeding hole, 66 is a terminal feeding claw, and 6
Reference numeral 7 represents a terminal supply lever.

The present invention has been made in view of the above problems, and in a so-called set type wire harness manufacturing method, a terminal crimping machine capable of crimping various kinds of terminals by one group and a tape with different types of terminals used for the crimping machine. The challenge is to provide.

Further, the terminal crimping machine is a terminal crimping machine including an anvil that supports terminals and a crimper that moves up and down by a ram facing the anvil, and the terminal crimping machine is provided with a plurality of pairs of anvils and crimpers corresponding to different terminals. It is characterized in that it is provided so as to be movable in a direction orthogonal to the elevation axis of the ram, and means for selecting and positioning a predetermined crimper and anvil with respect to the ram.

[0010]

In the tape with different types of terminals according to the present invention, a plurality of terminals including terminals of different types such as female and male, different sizes, shapes, etc. are arranged in advance in accordance with the order of crimping to electric wires by the wiring harness manufacturing program. Therefore, it suffices to intermittently feed the adhesive tape and crimp it in order, eliminating the loss time and wrong crimping for terminal selection. Further, the terminal crimping machine is provided with a plurality of pairs of crimpers and anvils as an assembly attached to and detached from the ram, and these can be selected and positioned according to the type of terminal. It is possible to provide a terminal crimping machine that does not require a mechanism or a crimping crimping mechanism, is downsized as a whole, and is suitable for space saving.
