Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ground terminal structure for a wire harness in a vehicle such as an automobile. The present invention also relates to a ground terminal mounting structure for fixing a wire harness ground terminal attached to an end of an electric wire of a vehicle wire harness to a vehicle body with a bolt.

[0002]

2. Description of the Related Art Wire harnesses are frequently used in vehicles such as automobiles. As shown in FIG. 1, a grounding system in these vehicles uses a minus (−)
By grounding the side to the body of the vehicle, the entire body is a grounded body. Therefore, several wire harness systems are combined in each area so that one or two ground wires are grounded to the body.
At this time, in order to secure the ground, the round terminals are generally bolted, and tapping type bolts are also used.

[0003] On the other hand, in recent years, the reuse of resources, that is, recycling has become a major issue, and has been spreading in various fields. Automotive parts are no exception, and there is a great deal of research on how to use them effectively.

In vehicles such as automobiles, attention has been focused on recovery of raw materials for steelmaking for blast furnaces from used vehicles, that is, recovery of high-quality scraps that can be used as raw materials for high-grade steel such as thin body plates of vehicles. To this end, in the dismantling work of used vehicles, recovery of non-ferrous metals, particularly separation of wire harnesses, has become a problem. In particular, among automobile wire harnesses, it is important how to reliably remove the wire harness from the vehicle body.

FIG. 2 shows a mounting structure of a ground terminal of a conventional automobile wire harness. In the figure, reference numeral 1 denotes a wire harness (for grounding), and a ground terminal 2 is attached to an end thereof. The ground terminal 2 has a round terminal shape,
In general, the bolt 3 is fixed to the body B of the vehicle by tightening. FIG. 3 shows the mounting state.

When removing such a grounding wire harness 1 from a used automobile, as shown in FIG. 4, the wire harness 1 is hoisted with a hoist (overhead crane) 4 or the like.
Pull up. However, the connection portion of the wire harness 1 by the connector tends to be broken at the lock portion and the coupling portion tends to come off. However, since the bolt of the ground terminal 2 is firmly tightened, a very strong force is required for removal. It is. In many cases, the wire harness 1 itself is torn off before the ground terminal portion is removed, and a part of the wire harness 1 remains on the body B side. For example, FIG. 4 shows the crimped portion of the wire being torn apart, leaving a small amount of coating. Also,
Indicates that the portion where the hoist 4 is hooked is torn, and a small amount of electric wire remains. As a result, the resin (the covering of the electric wire) remains on the body side, so that when the body (iron plate) is recycled, it is inevitable that impurities are mixed.

As described above, when impurities such as resin and copper are mixed into the recovered iron, the iron cannot be completely removed even if the iron is separated by a magnetic separator. In particular, when copper is mixed with iron, the iron becomes brittle, and high-quality iron cannot be regenerated. For normal shredder iron scrap, copper is 0.2
Currently, it is contained in an amount of about 0.3% by weight. However, in order not to make iron brittle, the copper content is required to be 0.06% by weight or less. Therefore, it has been desired to separate and collect such that a part of the ground wire harness does not remain.

Further, when removing the conventional grounding wire harness from the vehicle body, the fact is that the bolts are manually removed, and a lot of time and labor are required for sorting.

[0009]
