JPS63166507A - Assembly of electronic trim part for vehicle - Google Patents

Abstract

PURPOSE:To obtain a light weight part, to reduce the manufacturing cost and to improve the productivity, by inserting an electronic trim part between a first layer and a second layer to be impregnated with a synthetic resin and carrying out heat press molding thereof monolithically. CONSTITUTION:A roof lining 1 is formed by laminating a base material 2 and a surface material 3, both being made of a fibrous felt material impregnated with a thermosetting phenolic resin, between a top force 11 and a bottom force 12 and by carrying out heat press molding. In this case, a harness 7 on both ends of which connecters 6 an 8 are set is inserted between the base material 2 and the surface material 3 in such a way that the connecter 6 may be buried at the setting position of a room light 5 and is molded. The shape is adjusted by cutting around the circumferential part of the roof lining 1 at the bottom for trimming. The cutter blade can cut the base material 2 only as a relief is set at the harness part. The harness 7 adhered on the surface material 3 is thereafter separated off and taken up to cut off the unnecessary part of the surface material 3.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for assembling electrical components such as wire harnesses disposed in various parts of a vehicle, and particularly relates to a method for assembling electrical components such as wire harnesses arranged in various parts of a vehicle, and in particular to a method for assembling electrical components such as wire harnesses disposed in various parts of a vehicle. Concerning how to assemble parts.

<Prior Art> Conventionally, when installing vehicle electrical components such as wire harnesses in various parts of a vehicle, damage to the insulation coating due to contact with sharp edges or welded parts of the vehicle body, or damage to the wire harness due to commotion, etc. In order to avoid fatigue of the insulation coating due to rubbing between wire harnesses, a tape, tube, or special protector is applied or wrapped as a protective member on the bundle of insulation coating made of vinyl chloride, etc. of the wire harness, and the insulation coating is wrapped in a bundle of insulation coatings made of vinyl chloride etc. of the wire harness. It was attached to the inside of the timber or the vehicle body bracket.

However, in the case of roof lining, for example, the wiring locations for the harness are limited, and the use of the protective member increases the weight, which not only increases manufacturing costs but also complicates assembly work. There was a problem.

Therefore, as shown in Japanese Utility Model Publication No. 57-1539, a method has been proposed in which a notch is formed in a part of the interior material of the vehicle and the wire harness is held by hooking it. It is necessary to perform the work of forming and then hooking the wire harness, and although the wire harness can be easily held, the above-mentioned problems cannot necessarily be solved because the wire harness is exposed on the surface. Furthermore, Japanese Utility Model Application Publication No. 59-14741 proposes an instrument panel in which the wire harness is formed into a thin plate shape and sandwiched between the pad and the panel. Protection is ensured, but the process of making the wire harness into a thin plate and assembling the pad and panel requires assembling the wire harness at certain points, which is a complicated process, and the above-mentioned problems still arise. points cannot always be resolved.

<Problems to be Solved by the Invention> In view of the problems of the prior art, the main purpose of the present invention is to provide an automotive electrical component that is lighter in weight, reduces manufacturing costs, and improves productivity. The purpose is to provide an assembly method.

<Means for Solving the Problems> According to the present invention, such an object is achieved by assembling electrical components for a vehicle into a vehicle interior material (= J method, in which at least one side is impregnated with a synthetic resin. a step of sandwiching the electrical component between a first layer and a second layer; a step of integrally heat press molding the first layer and the second layer; and a step of integrally heat press molding the first layer and the second layer; This is achieved by providing a method for assembling electrical components for a vehicle, which is characterized by comprising a step of trimming the inside of the vehicle 'IAvJ'.

In this way, it becomes possible to assemble electrical parts such as a harness at the same time as molding the vehicle interior material outside the vehicle, and there is no need to provide a separate protective member. Furthermore, electrical components can be arranged in a free layout.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a roof lining 1 of a vehicle having a method of assembling electrical components for a vehicle according to the present invention, seen from the front of the upper part.

The roof lining 1 is formed by laminating a base material 2 and a surface material 3 made of the same material as this N)tA2 in accordance with the shape of the roof of a vehicle body (not shown) and integrally molding the same by hot pressing. A room lamp 5 is provided on the passenger compartment side of the roof lining 1 at approximately the center thereof, and a connector 6, a σ base material 2, and a surface material 3 are installed in the hole 1a opened for connection to the room lamp 5. Power is supplied from a car assembly (not shown) via a harness 7 buried between the two.

As shown in FIG. 2, such a roof lining 1 includes a base material 2 made of 1AuIft felt material impregnated with thermosetting phenolic resin between an upper mold 11 and a lower mold 12, and a surface It is formed by forming a vi layer of material 3 and hot press molding. At this time, connectors 6 are attached to both ends.
and 8 are inserted and molded between the base material 2 and the surface material 3 so that the connector 6 is embedded in the position where the room light 5 is installed.

Then, the shape is adjusted by cutting the vicinity of the peripheral edge of the roof lining 1 with the lower trimming base. At this time, in order to prevent the harness 7 from being cut along with the edge of the roof lining 1, the cutter blade (not shown) is provided with a relief in the harness portion, so that only the base material 2 is cut. Make it. After cutting the base material 2, the harness 7 stuck to the surface material 3 is peeled off and lifted, and unnecessary portions of the surface material 3 are cut. In addition, in order to connect the connector 6 and the room lamp 5, a hole 1a is created by cutting approximately the center of the roof lining 1 where the connector 6 is buried. By making the cut, the connector 6 and the room lamp 5 can be easily connected.

FIG. 3 is a diagram corresponding to FIG. 2 showing a second embodiment based on the present invention, in which the base material 13 is made of a porous urethane material impregnated with a phenol resin, and the surface is made of polyvinyl chloride. An intermediate material 1 made of foamed urethane is placed between the material 14 and the material 14.
5, and after pasting the surface material 14 and the intermediate material 115 in advance, the connector 6 and the σ harness 7 are inserted between the base ttA 13 and the intermediate material 15 and press-molded. The operation and effects are similar to those of the embodiment.

The base material is not limited to the felt material or urethane material as shown in the above embodiments, but may also be a gel glass material that can be processed at a temperature that does not melt the insulating coating of the harness. It may also be grass or the like.

Further, in the above embodiment, an example of application to a roof lining as a vehicle interior material has been described, but this may be, for example, a structure in which a large number of harnesses are buried in the rim 2 or an S' tray.

<Effects of the Invention> As described above, according to the present invention, it is possible to assemble electrical components such as wire harnesses and connectors in a free layout at the same time when forming the conductor interior material, and it is also possible to separately provide a protective member. Since this is not necessary, the number of parts is reduced, the weight is reduced, and the cost is reduced, which is extremely effective.
