BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a wiring apparatus for a vehicle according to the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a perspective view of a vehicle having a wiring device according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a wiring device of a vehicle according to an embodiment of the present invention.

1 and 2, a wiring device 100 of a vehicle according to an embodiment of the present invention includes a ceiling plate 105, a conductive pattern layer 110, and a fixed mounting portion 210 .

The sealing plate 105 is located above or below the ceiling panel 20 provided inside the ceiling of the vehicle 10. For the sake of convenience, the sealing plate 105 is shown inside the ceiling of the vehicle 10 so as to be positioned above the ceiling panel 20.

The conductive pattern layer 110 is formed by printing a conductive ink along a trajectory set on the sealing plate 105 provided in the ceiling of the vehicle 10. [ At this time, the sealing plate 105 is made of an insulating material such as a resin material. In particular, the conductive ink is printed on the sealing plate 105 by a piezoelectric inkjet method or the like, whereby the conductive pattern layer 110 is formed. The conductive ink is an ink liquid having conductor properties. That is, for the wiring of the vehicle 10, the conductive pattern layer 110 is typically formed by circuit-patterning the sealing plate 105 provided inside the vehicle 10, so that a floor panel (not shown) ), The weight is greatly reduced as compared with wiring by wiring harness. Of course, the sealing plate 105 may be the ceiling panel 20 itself. In addition, as the conductive pattern layer 110 is circuit-patterned on the sealing plate 105, a structure such as a clip (not shown) for fixing the wiring harness becomes unnecessary.

The wiring of the vehicle 10 serves to supply power from the battery 60 mounted in the engine room to each electrical component (not shown). The conductive pattern layer 110 of the sealing plate 105 receives power from the battery 60 through the A-pillars 30 of the vehicle 10 and receives the power from the A pillars 30 and the B pillar 30 40 and the C pillar 50 is applied to each electric component. Here, the electric component is an electronic product to be mounted on the vehicle 10 such as a reading window, an actuator for window operation, a black box, an interior lamp, and a tail lamp.

At this time, when the conductive pattern layer 110 is formed over one sealing plate 105, the sealing plate 105 must be replaced even when any part of the conductive pattern layer 110 is broken or short-circuited. Thus, the maintenance cost increases.

Accordingly, the sealing plate 105 is composed of the fragmented unit sealing plates 107, and each of the unit sealing plates 107 forms the conductive pattern layer 110 along the set trajectory. The conductive pattern layers 110 of the respective unit sealing plates 107 are electrically connected along the set trajectory. That is, the conductive pattern layer 110 is discontinuously patterned on the sealing plate 105 along the set trajectory.

In addition, when the conductive pattern layer 110 is formed on the inside of the A pillar 30, the B pillar 40, and the C pillar 50, it takes a lot of manufacturing cost, . Accordingly, it is preferable that the cable members 120 and 130 are wired inside the A pillar 30, the B pillar 40 and the C pillar 50. Particularly, as the cable members 120 and 130 are wired inside the A pillar 30, the B pillar 40, and the C pillar 50, the degree of freedom of laying out of the cable members 120 and 130 is improved.

More specifically, a power supply cable member 120 for electrically connecting one side of each of the conductive pattern layers 110 to the battery 60 is provided, and an electric component (not shown) corresponding to the other side of the corresponding conductive pattern layer 110 And a power supply cable member 130 for electrically connecting the power supply cable member 130 and the power supply cable member 130 to each other. Of course, the power supply cable member 120 and the power supply cable member 130 are not limited to the number of strands. At this time, the power supply cable member 120 should be firmly fixed to the unit sealing plate 107 on which the conductive pattern layer 110 is formed. Similarly, the power supply cable member 130 must be firmly fixed to the unit sealing plate 107 on which the conductive pattern layer 110 is formed.

FIGS. 3 and 4 are exploded perspective views of a wiring apparatus of a vehicle according to an embodiment of the present invention, and FIGS. 5 and 6 are sectional views of a wiring apparatus of a vehicle according to an embodiment of the present invention.

2, 3, and 5, the unit sealing plate 107 disposed at one edge of the sealing plate 105 has a power supply pin 142 (corresponding to one side of each corresponding conductive pattern layer 110) ). At this time, each unit sealing plate 107 penetrates the first via hole 112 to correspond to one side of the conductive pattern layer 110. The power supply pin 142 is inserted into the first via hole 112 and fixed by bonding or soldering. Of course, one or more power supply pins 142 are provided, and the first via holes 112 are formed in a number corresponding one to one to the power supply pins 142.

Further, the power supply pin 142 is covered so as to be partially exposed to the power supply housing 144. The power supply housing 144 is made of an insulating material as an injection material. Then, the power supply housing 144 is opened to both sides, and the power supply pin 142 is inserted to the rear side so as to be exposed to the front side.

In addition, the power supply cable member 120 is connected to the first mail connector 146 to be connected to the power supply pin 142. That is, the power supply cable member 120 is connected to the power supply pin 142 while the first mail connector 146 is coupled to the power supply housing 144. More specifically, the first mail connector 146 has a power supply connection pin 148 to correspond to the power supply pin 142 in a one-to-one correspondence. It is preferable that the power supply connection pin 148 is inserted into the power supply pin 142 to connect the power supply pin 142 to the power supply connection pin 148. Of course, it is preferable that the power supply housing 144 and the first mail connector 146 are detachably coupled by a locking device (not shown). Particularly, it is preferable that the power supply housing 144 is fixed to the corresponding unit sealing plate 107.

In one embodiment, the power supply housing 144 forms a first recessed groove 145 on the rear side for inserting the corresponding unit sealing plate 107. Thus, one side edge of the unit sealing plate 107 is inserted into the first recessed trench 145. At this time, the power supply pin 142 is stably supported in the power supply housing 144. At this time, the power supply housing 144 should be detached from the corresponding unit sealing plate 107. Thus, the first concave groove portion 145 projects a first coupling protrusion 149 on the inner side facing each other. In addition, the corresponding unit sealing plate 107 forms the first receiving recess 147 for receiving the first engaging protrusion 149. That is, when the unit sealing plate 107 is inserted into the first recessed groove portion 145 of the power supply housing 144, the first contact block 143 on both sides, which is divided by the first recessed groove portion 145, The coupling protrusion 149 is extended to a predetermined length. When the first coupling protrusion 149 is inserted into the first receiving recess 147, the first contact block 143 comes into contact with the corresponding surface of the unit sealing plate 107 facing the first contact block 143. Accordingly, the power supply housing 144 is firmly fixed to the sealing plate 105.

Referring to FIGS. 2, 4 and 6, a corresponding unit sealing plate 107 mounts a power applying pin 152 so as to correspond to the other side of each of the conductive pattern layers 110. At this time, the corresponding unit sealing plate 107 penetrates the second via hole 114 to correspond to the other side of the conductive pattern layer 110. The power applying pin 152 is inserted into the second via hole 114 and fixed by bonding or soldering. Of course, one or more power supply pins 152 are provided, and the second via holes 114 are formed in a number corresponding one-to-one to the power supply pins 152.

Further, the power applying pin 152 is covered so as to be partially exposed to the power applying housing 154. The power applying housing 154 is made of an insulating material as an injection material. Then, the power supply housing 154 is opened to both sides, and the power supply pin 152 is inserted to the rear side so as to be exposed to the front side.

In addition, the power supply cable member 130 is connected to the second mail connector 156 so as to be connected to the power supply pin 152. That is, while the second mail connector 156 is coupled to the power supply housing 154, the power supply cable member 130 is connected to the power supply pin 152. More specifically, the second mail connector 156 has a power supply connection pin 158 so as to correspond one-to-one to the power supply pin 152. It is preferable that the power supply connection pin 158 is inserted into the power supply pin 152 so as to be conductive. Of course, it is preferable that the power applying housing 154 and the second mail connector 156 are detachably coupled by a locking device (not shown). In particular, it is preferable that the power supply housing 154 is fixed to the unit sealing plate 107.

In one embodiment, the power supply housing 154 forms a second recessed groove 155 on the rear side for inserting the corresponding unit sealing plate 107. Thus, the unit sealing plate 107 is inserted into the second recessed groove 155. At this time, the power applying pin 152 is stably supported in the power applying housing 154. At this time, the power applying housing 154 should be detached from the unit sealing plate 107. Thus, the second recessed groove portion 155 projects the second engagement protrusion 159 on the inner side facing each other. In addition, the corresponding unit sealing plate 107 forms the second receiving recess 157 to accommodate the second engaging protrusion 159. That is, when the corresponding unit sealing plate 107 is inserted into the second recessed groove 155 of the power supply housing 154, the second contact blocks 153 on both sides, which are divided by the second recessed groove 155, The second fastening protrusions 159 are extended by a predetermined length. When the second coupling protrusion 159 is inserted into the second receiving groove 157, the second contacting block 153 facing the second coupling protrusion 159 comes into contact with the corresponding surface of the unit sealing plate 107. Accordingly, the power supply housing 154 is firmly fixed to the sealing plate 105.

7 is a cross-sectional view of a sealing plate of a vehicle according to an embodiment of the present invention.

Referring to FIG. 7, the sealing plate 105 formed of the unit sealing plate 107 forms a coating layer 160 by coating a coating liquid before the conductive pattern layer 110 is formed. That is, the coating layer 160 is coated with the coating liquid on the upper surface of the unit sealing plate 107. Then, conductive ink is applied to the upper surface of the coating layer 160 to form the conductive pattern layer 110. The reason for forming the coating layer 160 is that blurring occurs when the conductive ink is directly applied to the unit sealing plate 107.

In addition, an insulating layer 170 is formed on the upper surface of the conductive pattern layer 110. The insulating layer 170 is formed by printing an insulating ink on the upper surface of the conductive pattern layer 110. The insulating ink is coated on the upper side of the unit sealing plate 107 including the conductive pattern layer 110 or only on the upper side of the conductive pattern layer 110 and then dried by UV beam irradiation or the like. At this time, the insulating layer 170 plays a role of having high wettability and adhesiveness when adhering to the conductive pattern layer 110, and protects the conductive pattern layer 110. Particularly, the insulating ink forming the insulating layer 170 is preferably an ink liquid having a high dimensional stability because the form of the insulating ink is hardly deformed at the time of curing.

A waterproof layer 180 is formed on the insulating layer 170. The waterproof layer 180 forms the uppermost layer of the unit sealing plate 107 and is coated with a film or coated with a transparent silicone resin and then dried to protect foreign substances such as water from entering the conductive pattern layer 110 .

FIG. 8 is a perspective view showing a unit sealing plate and a ceiling panel according to an embodiment of the present invention. FIG. 9 is a cross-sectional view of a unit sealing plate and a ceiling panel according to an embodiment of the present invention.

2, 8, and 9, the unit sealing plate 107 must be fixedly coupled to the ceiling panel 20, which is usually provided inside the ceiling of the vehicle 10. [ At this time, a unit sealing plate 107 located along the trajectory of the sealing plate 105 among the plurality of unit sealing plates 107 is bound to the ceiling panel 20, and the neighboring unit sealing plates 107 are opposed to each other By inserting the edges together, all the unit sealing plates 107 are fixed. That is, the hook 212 protrudes from the lower surface of the unit sealing plate 107 disposed along the edge of the sealing plate 105.

The unit sealing plate 107 located along the trajectory of the ceiling plate 105 is fixed to the ceiling panel 20 by the fixing portion 210. That is, the fixed mounting portion 210 serves to connect and fix the unit sealing plate 107 to the ceiling panel 20.

Here, the fixed mounting portion 210 includes a hook 212 and a hook hole 214.

The hook 212 protrudes from the lower surface of the corresponding unit sealing plate 107. At this time, the hooks 212 are preferably integrally formed with the unit sealing plate 107, and can be deformed into various shapes. Of course, the number of hooks 212 is not limited.

Further, the hook holes 214 are formed in the ceiling panel 20 so as to correspond one-to-one with the hooks 212, respectively. Thus, the hooks 212 are prevented from being detached from the corresponding hook holes 214, so that each of the unit sealing plates 107 is fastened to the ceiling panel 20.

Of course, the unit sealing plate 107 may be bonded to the interior material other than the ceiling panel 20.

FIG. 10 is an enlarged view showing a structure in which a conductive pattern layer is jumping between unit sealing plates according to an embodiment of the present invention.

As shown in Fig. 10, the conductive pattern layer 110 is formed in a non-contact manner by the separated unit sealing plate 107. Fig. At this time, the conductive pattern layer 110 should have continuity along the set trajectory. Thus, the non-continuous conductive pattern layer 110 on the set locus is electrically connected by the jump portion 220. That is, the jumping portion 220 serves to electrically connect the non-continuous conductive pattern layer 110 by the unit sealing plate 107.

The jump portion 220 includes a terminal pin 222, a terminal groove portion 224, and a fuse member 226.

The terminal pins 222 are mounted on each of the unit sealing plates 107 so as to correspond to the adjacent conductive pattern layers 110. At this time, the unit sealing plate 107 penetrates the terminal hole 223 at a position corresponding to the conductive pattern layer 110. The terminal pin 222 is inserted into the terminal hole 223 and comes into contact with the conductive pattern layer 110 at the same time. At this time, the terminal pin 222 is inserted into the terminal hole 223 and fixed by bonding or the like.

The terminal groove portion 224 is recessed on the upper side of each of the terminal pins 222.

In addition, the fuse member 226 serves to electrically connect the neighboring conductive pattern layers 110 on the set trajectory. More specifically, the fuse member 226 has bridges 227 that are inserted and electrically connected to correspondingly adjacent terminal groove portions 224, respectively. The bridge 227 is inserted into the terminal groove 224 of the corresponding terminal pin 222. At this time, the bridge 227 comes into contact with the terminal pin 222 and maintains a state of being energized. The pair of bridges 227 are electrically connected to each other inside the fuse member 226.

The unit sealing plates 107 disposed along the edge of the sealing plate 105 are bound to the ceiling panel 20 by the hooks 212 and the adjacent unit sealing plates 107 are connected to the fuse member 226 So that all of the unit sealing plates 107 are engaged with each other.
