Abstract

The present invention uniformly wraps the wire harness that supplies electricity to various mechanical, electrical, and electronic devices installed in the engine room of the vehicle so that the wire harness is shielded from the high temperature of the engine and noise is not generated even if it is vibrated. It is devised for the structure of the pad.

Description

Structure of pad that serve to protect wire harness in car engine-room}

The present invention is designed for the structure of the electric wire protection pad of the car engine room. When the car engine is operated to drive, the inside of the car engine room has a high heat emitted from the engine. Wire harnesses considering the heat resistance in which the devices are mounted and electrically connected to each other organically with wires, so that a relatively large number of electric wires are connected between each device and the devices, in particular, the wires used in the engine room are bundles of several strands. I'm using.

In particular, wire harnesses in which wires used to supply electricity to each electric and electronic device mounted in an engine room having high heat in general are set in a bundle in a bundle. This wire harness acts as the central nerve of the car and the electric passage that operates various electrical equipments smoothly. However, these wire harnesses are relaxed by long time elapsed or constantly generated vibrations, and the noises are caused by bumping against peripheral devices. There are cases where several wires are partially bound, so the unbounded spirals are disordered and the engine room itself looks very messy.

<Code Description of Main Parts of Drawing>

1. PAD 2,2a. Raising 3. Pad heart material

4,4a. Adhesive layer 5. Glass fiber 6,6a. Double sided adhesive tape layer

7. Aluminum sheet layer 8.

In order to solve the problems such as vibration, noise, and poor appearance of the conventional wire harness as described above, the present invention has a sufficient buffering property and reflects high heat so that the life of the wire can be extended while maintaining a uniform state throughout the wire. Based on the accompanying drawings devised to solve the problems of the conventional wire harness by winding the present invention will be described below.

The pad structure of the wire harness protection pad (PAD) 1 of the automobile engine room, which is embodied by the present invention, is made of a composite material such as flame retarded polyester and the like, and a fine brushed fabric (2) (2a) is formed on the upper and lower surfaces thereof. (3) On both the upper and lower surfaces, respectively, the double-sided adhesive tape layers 6 and 6a coated with the adhesive layers 4 and 4a are laminated on the upper and lower surfaces, and the upper and lower surfaces of the adhesive tape layer 6 The glass fiber 5 is bonded and the aluminum sheet layer 7 of predetermined thickness is laminated on the upper surface of the glass fiber 5 and the paper 8 is attached to the adhesive layer 4a of the adhesive tape layer 6a. The structure of the wire harness protection pad 1 of the automobile engine room implemented above is comprised.

The double-sided adhesive tape (6) (6a) of the pad (1) implemented according to the present invention configured as described above is preferably made of a glass fiber (5) in consideration of the damage to the pad core material (3) ) Is preferably a synthetic fiber such as a flame retardant polyester having a buffering capacity.

By winding the wire harness protection pad implemented by the present invention configured as described above to the wire harness surface at a constant pitch, the appearance is clean and the pad core material absorbs the shock during vibration and the high temperature inside the engine room penetrates into the pad 1. By heat reflection of the aluminum sheet layer 7 adhered to the pad outer surface, the wire harness is shielded from heat, thereby extending the life of the wire harness.

Claims (1)

In constructing the structure of the pad 1 for protecting the wire harness of the automobile engine room, the pad core material 3 is made of a composite material such as flame retarded polyester and the like, and fine brushed fabrics 2 and 2a are formed on the upper and lower surfaces. Each of the double-sided contact tape layers 6 and 6a coated with the adhesive layers 4 and 4a on the upper and lower surfaces thereof is also laminated on the lower surface, and the glass fiber is formed on the upper surface of the adhesive layer 4 of the adhesive tape layer 6. (5) to bond the aluminum sheet layer (7) of predetermined thickness on the upper surface of the glass fiber (5), and to attach the film (8) to the adhesive layer (4a) of the adhesive tape layer (6a).
