DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness assembly buried in urethane insulation of a refrigerator.

[0002]

2. Description of the Related Art Conventionally, harnesses have been bundled into a plurality of bundled harnesses and buried in urethane insulation of a refrigerator. That is, as shown in FIG. 5, the lower figure a is attached, and a board c provided with the holder b is prepared along the lower figure a. Next, the harness d is arranged along the lower figure a and hooked on the holder b. Then, the bundled portion is stopped with a tape e so as not to be separated, and then removed from the board c to form an assembly f.

[0003] The assembly f of the harness d thus made
Was attached to the back of the hood liner g, as shown in FIG.

[0004]

However, in the case of the above-mentioned assembly f of the harness d, since the harness d is bundled by the tape e or the like, the cross section becomes circular and the size becomes large. Therefore, as shown in FIG. 7, when this assembly f is embedded in the urethane heat insulating material h of the refrigerator, the harness d
Only the thickness i of the nearby heat insulating material h is locally reduced with respect to the entire thickness j, so that a sufficient heat insulating effect cannot be obtained, resulting in a disadvantage that dew condensation occurs from this portion. Also, when urethane is poured, only the gap in the vicinity of the harness d is locally narrowed, so that the urethane flow is deteriorated, and voids and the like are generated, which causes inconvenience such as dew condensation. for that reason,
It is conceivable to increase the thickness of the urethane heat insulating material layer as a whole, but in this case, there is a disadvantage that the appearance of the refrigerator in relation to the capacity becomes large.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a harness assembly capable of improving the heat insulating effect and preventing poor filling of urethane heat insulating material. .

[0006]

A harness assembly according to the present invention for solving the above-mentioned problems is a harness assembly buried in urethane insulating material of a refrigerator-freezer.
A harness is sandwiched and adhered between two flexible sheet materials in a state of being arranged in a plane.

Further, any one of the sheet materials is made of release paper having an adhesive layer.

Further, the sheet material is made to have air permeability.

[0009]

According to the present invention, a harness is provided with a flexible
Since it is sandwiched and adhered between two sheet materials in the state of a flatly arranged assembly, it becomes a plate with an even thickness as a whole, and even if it is embedded in urethane insulation material, it will be a local insulation material Does not become thin. In addition, make the sheet material breathable.
The harness assembly and place urethane insulation
When filling and foaming, generation of voids is prevented.

Further, since one of the sheet materials is release paper having an adhesive layer, after releasing the release paper, the adhesive layer is pressed against the back surface of the hood liner to attach the harness assembly. can do.

Furthermore, since the sheet material is transparent,
When placing the harness, you can check the lower diagram of the board and check the bonding condition.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a use state of the harness assembly 1.

That is, in the harness assembly 1, the harness 11 is provided between the two flexible sheets 12 and 13.
They are sandwiched and adhered in a state where they are arranged in a plane.

The harness assembly 1 is assembled as follows. That is, as shown in FIG. 2, first, the sheet material 12 is arranged on the lower diagram for disposing the harness 11 and the board 2 on which the pins 21 used for fixing the harness 11 are erected. A hole 14 is formed in the sheet material 12 in advance at a position corresponding to the pin 21 on the board 2 so that the sheet material 12 can be in close contact with the board 2. In this close contact state, the board 2 is formed so as to be transparent so that the following figure can be confirmed, and the surface thereof is coated with an adhesive.

Next, referring to the following figure on the board 2,
The harness 11 is hooked on the pin 21 and the harness 11 is attached to the surface of the sheet material 12.

After all the harnesses 11 have been attached, a sheet material 13 is further placed on the surface of the sheet material 12. The sheet material 13 is coated with an adhesive on the back surface facing the harness 11 and is formed to be transparent like the sheet material 12.

Then, the sheet material 12 and the sheet material 13 are bonded together, and the harness 11 is sandwiched between the two sheet materials 12 and 13.

Thereafter, the board 2 is pulled out, and the harness assembly 1 is completed.

The harness assembly 1 has a predetermined connector 15 attached to an end of each harness 11 and is attached to the back of the hood liner 4. At this time, since the harness assembly 1 includes the flexible sheet materials 12 and 13 and the bendable harness 11, the harness assembly 1 can be stuck to the back surface of the hood liner 4 without gaps. This attachment can be performed by applying an adhesive or the like to the surface of the sheet material 12. Alternatively, the sheet material 12 may be a release paper having an adhesive layer, and the release paper may be peeled off and adhered to the hood liner 4 when the sheet material 12 is adhered to the hood liner 4.

Thereafter, as shown in FIG. 3, an outer shell 5, a base plate 6,
Electrical box 7, back plate 8, bottom plate 9
The space 10 (see FIG. 4) for providing the urethane heat insulating material 3 is formed.

Then, a urethane liquid is injected from a urethane liquid injection port 81 provided in the back plate 8, and the space 1
0, and the urethane heat insulating material 3 is formed in the space 10.
Is filled. At this time, since the harness assembly 1 is formed in a sheet shape, the flow of the urethane liquid and the urethane insulation 3
Can be filled without hindering foaming. Also,
If the sheet materials 12 and 13 are made of a material having air permeability, generation of voids at the time of urethane foaming can be eliminated, and a good urethane heat insulating material 3 can be obtained.

After that, necessary parts (not shown) are attached to form a refrigerator-freezer (not shown).

The refrigerator-freezer thus constructed (not shown)
Since the harness assembly 1 is formed in a sheet shape as shown in FIG.
Can be filled with the urethane heat insulating material 3, and the occurrence of dew condensation can be prevented.

[0025]

As described above, according to the present invention, the entire plate becomes a plate having a uniform thickness, and even if it is buried in the urethane heat insulating material, the thickness of the heat insulating material is not locally small. Can be prevented from occurring. Also, harness assembly
When placing and foaming urethane insulation, voids
Good urethane with no defects
Insulation material can be obtained.

After the release paper is peeled off, the harness assembly can be attached by pressing the pressure-sensitive adhesive layer against the back surface of the hood liner, so that the harness assembly can be easily attached.

Further, by making the sheet material transparent,
Confirmation and bonding of the board below when placing
Because you can check the condition, always use a stable harness assembly
Obtainable.
