SOLUTION: For attaching a dash insulator 10, first the lower end 14 of a dash insulator main body 11 is placed on a cab floor 31, a retainer stop hole is fitted in a retainer while aligning a blower opening 15 with the blower opening 33 of a dash panel 32 and then the dash insulator main body 11 is positioned in the dash panel 32. A stopper 25 is hung through the blower openings 15 and 33 in the blower opening 33. Then, the dash insulator main body 11 is pressed and fixed to the dash panel 32 by the retainer. Then, a cooler unit 35 is attached to the dash panel 32 by aligning the same with the blower opening 33 and holding a water proof gasket 36.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dash insulator used for a dash panel of an automobile.

[0002]

2. Description of the Related Art In a cooling device used for an automobile, for example, a truck, a cooler unit having a built-in evaporator is attached to a dash panel.
The panels are soundproofed and insulated so that the dash insulators are retained on the inside surface to block out noise outside the vehicle and to insulate them. In this cooling system, the blower built into the cooler unit uses the dash
Positioned opposite the blower opening of the panel, and a wire harness is coupled below the blower side of the cooler unit. In such a layout, water droplets condensing on the surface of the cooler unit may drip at the connection point of the wire harness,
Since the truck is washed with water in the cab, a waterproof connector is generally used at the connection point.
And such protections were costly.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to protect a connecting portion of a wire and a harness from water drops and car wash water without complicating an assembling operation, and to connect the wire and harness without a waterproof connector. To provide a dash insulator.

[0004]

Means corresponding to the object and the operation thereof
A dash insulator body attached to the inner surface of the dash panel with the blower opening aligned with the blower opening of the dash panel, and a top end so that it can be inserted into the blower openings. It has a stopper that protrudes, is overlapped with the dash insulator main body, and is joined to the lower end side of the dash insulator main body so that it can be folded back,
And, when the dash insulator main body is attached to the dash panel, the stopper is hooked through the blower openings, and a wire / harness waterproofing sheet for keeping the dash insulator main body superimposed on the dash insulator main body is included. When the dash insulator body is attached to the dash panel, the stopper is removed from the blower opening, and the waterproof sheet is folded over the connection point of the wire harness.

Punched out.

[0007] The wire harness waterproof sheet 13 is
It is cut into a predetermined shape and size from a vinyl chloride sheet. Since the wire harness waterproof sheet 13 is required to have self-sustainability and foldability in addition to waterproofness, a relatively thin vinyl chloride sheet is used. More specifically, the waterproof sheet 13 is provided with the blower openings 1.
A stopper 25 protruding from the upper end 23 so that the retainer stopper hole 27 can be inserted into the predetermined position.
28 and the vinyl chloride sheet 12
The dash insulator body 11 is superposed on the dash insulator body 11 and is joined to the lower end side of the dash insulator body 11 in a foldable manner.

The waterproof sheet 13 is connected to the stopper 25
Into the blower opening 15 and the retainer stopper holes 27 and 2
8 is positioned in the dash insulator main body 11 in the left-right direction with the retainer retaining holes 20 and 21 of the dash insulator main body 11, respectively.
The lower end 24 is connected to the dash insulator main body 1.
1 is vertically positioned on the dash insulator main body 11 in accordance with the lower end 14 thereof, and FIG.
The lower end portion 26 is joined to the dash insulator body 11 and the vinyl chloride sheet 12 as shown by hatching in FIG. The lower end portion 26 has a joint width of the wire harnesses 37, 38, 3 to avoid water pools.
9, 40, 41, 42, 43 and connection points 44, 45
It is desirable that the height be determined so as to be folded back over. Of course, the waterproof sheet 13 may be joined between the lower end 24 and the lower end 14 of the dash insulator main body 11. Further, the lower end 24 of the waterproof sheet 13 is attached to the dash insulator body 11.
May be cut to a size located above its lower end 14.
