These electrical components are supplied with voltage from the capacitor 65.

The wiring 90 (see Fig. 4) refers to a lead that interconnects each electric component of the vehicle 10 and implements the circuit.

4 is a schematic view of a vehicle 10 in which one or more wires 90 are disposed.

4, the wiring 90 is connected to the main wiring 90-1 disposed in front of the vehicle 10, the engine wiring 90-2 connected to the engine, and the capacitor 65, A voltage supply line 90-3 for supplying a voltage to the driver's seat 10 and floor wirings 90-a and 90-b for connecting wirings disposed in front of and behind the vehicle 10, Front door wiring lines 90-5 and 90-6 disposed in the adjacent doors 71 and 72 and rear door wiring lines 90-7 and 90-90 disposed in the doors 73 and 74 close to the rear seats 23 and 24, A wiring 90-4 connecting the electric components mounted on the driver's seat 21 and the front passenger seat 22 and a wiring 90-9 connecting the electric components mounted on the rear seats 23 and 24 .

5 is an external view of the hot wire pattern 90-10, the antenna pattern 90-11, and the guard pattern 90-12 mounted on the rear glass 39 of the vehicle 10. Fig.

Referring to FIG. 5, the heat ray pattern 90-10 generates heat by using electric current, thereby transferring heat to the rear glass 39. FIG. As a result, the liquid frost on the rear glass 39 is vaporized due to heat, and fogging is prevented.

The antenna pattern 90-11 is mounted on the rear glass 39 to receive radio waves.

The antenna pattern 90-11 can receive radio waves of a specific frequency band and can receive radio waves of, for example, the AM radio broadcast band.

In this case, the radio wave in the AM radio broadcast band is medium-frequency wave of 535 Hz or more and 1605 Hz or less that is amplitude modulated (AM), and is susceptible to noise. In addition, the radio wave in the AM radio broadcasting band is low in transmittance of concrete, and thus is difficult to be transmitted in a room in a large city. In addition, radio waves in the AM radio broadcast band have a characteristic of propagating along the surface of an object.

Hereinafter, the radio wave in the AM radio broadcast band will be described as an example, but the antenna pattern 90-11 can receive various radio waves such as radio waves in the FM radio broadcast band.

The antenna pattern 90-11 is disposed close to the heating wire pattern 90-10 on the rear glass 39. The antenna pattern 90-11 is also placed close to the C-pillar 38 of the vehicle 10 and other wirings 90 mounted on the package tray 35.

Generally, the air and the rear glass 39 of the vehicle 10 are heated by the air or the rear glass 39 due to factors such as a nonconductive material, water vapor in the air, or impurities adhering to the rear glass 39 of the vehicle 10 So that current can be energized.

In this case, the noise generated from the wirings 90 adjacent to the antenna pattern 90-11 can be transmitted to the antenna pattern 90-11 using the air or the rear glass 39 as a medium.

As a result, the radio wave reception performance of the antenna pattern 90-11 is lowered.

Therefore, the vehicle 10 according to the embodiment arranges the guard pattern 90-12 between the antenna pattern 90-11 and the other wiring 90 mounted on the rear side of the vehicle 10, so that the guard pattern 90 -12) absorb the noise generated from the other wirings 90 instead of the antenna pattern 90-11.

Hereinafter, the hot wire pattern 90-10 will be described as an example of another wire 90 mounted on the rear side of the vehicle 10. [

6 is a frontal layout view of the hot wire pattern 90-10, the antenna pattern 90-11, and the guard pattern 90-12 viewed from the inside of the vehicle 10, The antenna pattern 90-11, and the guard pattern 90-12, which are viewed from the side of the antenna pattern 90-10.

6 and 7, the antenna pattern 90-11 and the hot wire pattern 90-10 are disposed on the rear glass 39 inside the vehicle 10 at a distance.

The guard pattern 90-12 is disposed between the antenna pattern 90-11 and the hot wire pattern 90-10.

In this case, the guard pattern 90-12 is also spaced apart from the antenna pattern 90-11 and the heating line pattern 90-10.

Both ends of the guard pattern 90-12 are connected to the ground terminal G (see Fig. 4) of the capacitor 65 of the vehicle 10. [

Both ends of the guard pattern 90-12 are connected to the ground terminal G so that the guard pattern 90-12 can flow the noise absorbed from the heating line pattern 90-10 to the ground terminal G. [

According to one embodiment, the guard pattern 90-12 may be disposed in close proximity to the hot wire pattern 90-10 such that the absorption rate of the noise is increased.

7, the distance d1 between the guard pattern 90-12 and the hot line pattern 90-10 is larger than the distance d1 between the hot line pattern 90-10 and the antenna pattern 90-11 the guard pattern 90-12 may be arranged so as to be smaller than the predetermined value by a predetermined value. In this case, a preset value can be obtained experimentally.

According to another embodiment, the guard pattern 90-12 may be implemented with a conductor having a low impedance Z so that the absorption rate of the noise is increased.

The impedance Z1 represents the degree of difficulty of current flow, and the impedance Z1 between the guard pattern 90-12 and the hot line pattern 90-10 is less than the impedance Z1 between the hot line pattern 90-10 and the antenna pattern 90-11 Z2), it is possible to cause the noise to be more absorbed in the guard pattern 90-12 than the antenna pattern 90-11.

For example, if the impedance Z1 between the guard pattern 90-12 and the hot line pattern 90-10 is equal to or smaller than the impedance Z2 between the hot line pattern 90-10 and the antenna pattern 90-11 A guard pattern for small size may be implemented. Even in this case, the preset value can be obtained experimentally.

According to another embodiment according to Fig. 8, the guard pattern 90-12 may be implemented as a plurality of disconnection lines.

Generally, an AC (AC) signal has a characteristic that the higher the frequency, the more the surface is energized. This is called a skin effect.

When the noise is an AC signal, this skin effect can occur when noise is absorbed in the guard pattern 90-12.

Therefore, the guard pattern 90-12 according to another embodiment is realized by a plurality of disconnection lines, thereby increasing the surface area of the conductor and increasing the skin effect, thereby absorbing more noise.

According to another embodiment of FIG. 9, the guard pattern 90-12 may be embodied as a conductor having a predetermined thickness.

Fig. 10 is a view for explaining the characteristics of the conductor.

10, the conductor has a thickness t and a length L, and the cross-section A of the conductor is embodied in a circle having a radius r. The radius r of the lead is half of the thickness t and the cross-section A is proportional to the square of the radius r.

Due to its own physical properties, the conductors have an impedance. The impedance is inversely proportional to the cross-sectional area (A) of the conductor, and is proportional to the length (L).

Therefore, as the impedance of the guard pattern 90-12 made of conductive lines increases, the noise absorbed by the guard pattern 90-12 decreases.

9, the guard pattern 90-12 is implemented so that the thickness t of the guard pattern 90-12 is greater than a preset value, and the impedance of the guard pattern 90-12 It is possible to increase the noise absorption rate of the guard pattern 90-12.

Even in this case, the preset value may be an experimentally obtained value.

According to another embodiment, an antenna pattern 90-11 disposed on the rear glass 39 of the vehicle 10, an antenna pattern 90-11 disposed on the rear glass 39 of the vehicle 10, The guard pattern 90-12, which is disposed between the hot line pattern 90-10 and the antenna pattern 90-11 and the hot line pattern 90-11 and connected to the ground terminal G of the capacitor 65, The present invention can be embodied as a vehicle-use glass wiring device.

The glass wiring apparatus for a vehicle may be disposed on the side glass 50 and the front glass 31 as well as being disposed on the rear glass 39 of the vehicle 10 as described above. It is also possible for the vehicle-use glass wiring apparatus to include, in addition to the heat ray pattern 90-11, another wiring pattern 90-10 which is disposed apart from the antenna pattern 90-11 on the rear glass 39.

The description of the wiring pattern, the antenna pattern, and the guard pattern included in the vehicle-use glass wiring apparatus is omitted in the description of the vehicle 10.

Hereinafter, a method of manufacturing a glass wiring apparatus for a vehicle will be described. 11 is a flowchart of a method for manufacturing a vehicular wiring device.

The patterns may be arranged in a single strand, or may be arranged in a plurality of single strands.

Subsequently, the electric component corresponding to the antenna pattern is connected to the antenna pattern, and the electric component corresponding to the heating line pattern is connected to the heating line pattern (S1120).

The electrical component corresponding to the antenna pattern may be, for example, an AVE device and a capacitor that provide radio service to the driver.

The electric component corresponding to the hot wire pattern may be, for example, the front wiring and the capacitor of the vehicle.

Next, a guard pattern is placed or mounted between the antenna pattern and the hot line pattern on the rear glass (S1130).

In this case, the guard pattern can be arranged so that the distance between the guard pattern and the hot line pattern is smaller than the distance between the hot line pattern and the antenna pattern by a predetermined value.

The guard pattern may be implemented so that the impedance between the guard pattern and the hot line pattern is smaller than the impedance between the hot line pattern and the antenna pattern by a preset value.

Further, the guard patterns may be arranged in a plurality of disconnection lines.

In addition, a guard pattern may be implemented so that the guard pattern is realized by a plurality of disconnection lines.

Further, a guard pattern may be implemented so that the conductor of the guard pattern has a thickness equal to or larger than a predetermined value.

Then, both ends of the guard pattern and the ground terminal of the capacitor are connected (S1140).

Thus, both ends of the guard pattern are connected to the ground terminal of the capacitor, so that the potential is maintained at 0V, and the noise received from the hot line pattern flows to the ground terminal.

On the other hand, in the above-described method of manufacturing the glass wiring device, the glass wiring device is arranged on the rear glass. However, the present invention is not limited to this and includes arranging the glass wiring device on the front glass or the side glass of the vehicle.
