ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a grommet water stopping method and a wire-harness loosening jig which can loosen electric wires of a wire-harness in a grommet to surely inject a sealing agent among electric wires of the wire harness.
2. Description of the Prior Art
FIG. 16
illustrates a conventional grommet water stopping method in which a wire harness
83
is passed through a small diameter portion
82
of a resilient cup-shaped grommet
81
made of synthetic resin and the cup-shaped grommet
81
is filled with a sealing agent
84
in order to prevent water from invading from the small-diameter portion
83
. The sealing agent
84
is in a muddy liquid state which will be converted into a rubber state.
The above prior art, however, has a disadvantage in that water invades from gaps
85
among the electric wires constituting the wire harness
83
.
In order to overcome the above disadvantage, J-UM-A-1-58222 proposes a technique in which, as shown in
FIG. 17
, each of electric wires has a wave curve
88
and a sealing agent
90
is caused to fill gaps
89
formed by the wave curves
88
. In this technique, to form wave curves
88
for each electric wire, one by one is, very troublesome. Where the curves
88
are not located within grommet
91
, gap
89
may not be formed between the electric wires and the sealing agent
90
may not fill the gaps between the electric wires.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a grommet water-proof method and an electric wire loosening jig which can inject a sealing agent between the electric wires simply and without much labor and without difference in work.
In accordance with one aspect of the present invention, the operation of rotating and inverting a movable-side clamping portion or the operation of shifting such clamping portion permits a wire harness to be compressed in an axial direction so that the electric wires of the wire harness can be easily loosened. For this reason, a sealing agent can be injected among the electric wires without much labor and without difference in work.
In accordance with another aspect of the present invention, when the movable-side clamping portion is inverted, such clamping portion is shifted towards a fixing-side clamping portion. Thus, the degree of loosening the wire harness can be further increased at the rotating angle equal to the above aspect of the present invention. This increases working accuracy in the operation of loosening the wire harness.
In accordance with still another aspect of the present invention, a rachet mechanism prevents the movable-side clamping portion from being inverted at the time of twisting the wire harness, thus increasing workability.
The above and other objects and features of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings.
