Description

The present invention relates to a vehicle panel such as a ceiling panel of an automobile.

  For example, an electrical component such as a room lamp is mounted on a ceiling panel of an automobile, and a harness for supplying power to the electrical component is generally assembled (for example, Patent Document 1). See). The harness is configured by attaching a connector to end portions of a plurality of electric wires.

  When laying an electric wire on a ceiling panel of an automobile, it is necessary to accurately grasp the electric wire laying specifications determined in advance according to the vehicle type and grade, and to set the laying position and length of the electric wire in an appropriate state. On the other hand, in recent years, the number of electrical components mounted on automobiles has increased, and wire harnesses connected to these electrical components often have many branches of wires, and the wiring mode of the wires is often complicated. Moreover, even if the vehicle type is the same, the wiring mode of the electric wire is often different for each grade. Therefore, the work of accurately sensing such a difference and appropriately assembling the wire harness to the ceiling panel is cumbersome and has poor workability.

  Patent Document 1 describes means for completing a wire harness assembled to a ceiling panel by attaching electric wires to the ceiling panel of an automobile using a double-sided tape. According to such means, the conventional general means, that is, a wire harness having a predetermined specification is produced using a dedicated jig for producing a wire harness, and then compared with a means for assembling the wire harness to a ceiling panel. Then, the workability becomes good.

  However, in the case of adopting the means described in Patent Document 1, even if an attempt is made to apply a double-sided adhesive tape for electric wires to a ceiling panel, the attaching position is not clarified, and where the double-sided adhesive tape is applied. It is difficult to see if it is appropriate. In addition, the end of the wire is connected to the electrical component via a connector, but the mounting position of the electrical component is often different depending on the vehicle type and grade, so the proper length when connecting the electrical wire to the electrical component is It is also difficult to grasp the length and set the appropriate length.

It is a principal part top view of the state which attached the connector to the electric wire shown in FIG.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  The ceiling panel P shown in FIG. 1 is attached to the lower surface side of the roof 10 of the automobile 1 and is entirely in the form of a resin plate, for example. The ceiling panel P is attached to the lower surface side of the roof 10 with the wire harness H assembled on the upper surface side thereof. The wire harness H has a connector 3 attached to the tip of the electric wire 2 and is manufactured by a method described later.

  As shown in FIG. 2, the ceiling panel P is provided with an opening 90 for attaching the room lamp 4, an electric wire laying path 6, a mark portion 7 for measuring, and a display portion 8 for instructing electric wire arrangement. Yes. These portions are three-dimensional parts that are simultaneously molded during resin molding of the ceiling panel P. The room lamp 4 is attached to the lower surface side of the ceiling panel P.

  The electric wire laying path 6 is a path for laying the electric wire 2, and is a concave groove provided on the upper surface of the ceiling panel P. More specifically, the electric wire laying path 6 is a concave groove formed in a series from, for example, a predetermined position of the front edge 91 of the ceiling panel P to a predetermined position near the opening 90. In the present embodiment, the electric wire laying path 6 is substantially L-shaped in plan view, and extends from the front edge 91 of the ceiling panel P in the front-rear direction of the ceiling panel P (the left-right direction in FIG. 2A). 1 path 6a and the 2nd path | route 6b extended in the width direction of the panel P for ceilings from the end of this 1st path | route 6a.

  As shown in FIG. 4, the measuring mark portion 7 has a length of the protruding portion 21 of a predetermined length in a state in which the tip end portion of the electric wire 2 protrudes from the one end portion 60 of the electric wire laying path 6. This is a portion for defining the length L1. The protruding portion 21 is a portion that is bent toward the opening 90 side to be connected to the room lamp 4 as indicated by an arrow N1 in FIG. In FIG. 2, the measuring mark portion 7 is provided at a position separated from the one end portion 60 of the electric wire laying path 6 by a distance L1. Further, the measuring mark portion 7 is located on the extension line of the second path 6 b of the electric wire laying path 6. As shown in FIG. 2B, the measuring mark portion 7 has a convex shape protruding upward from the upper surface of the ceiling panel P. In addition, the mark part 7 for measurement may not be on the extension line of the 2nd path | route 6b, and may be shifted | deviated from on this extension line.

  The display unit 8 for indicating the electric wire arrangement indicates a correct arrangement of the electric wires 2 when connecting the electric wires 2 and the connectors 3. For example, the display unit 8 is a portion in which characters such as “white” and “red” are displayed side by side. is there. These characters are characters expressed by narrow grooves or protrusions. The connector 3 is used for connection with a connector (not shown) of the room lamp 4. The electric wire 2 is obtained by coating a metal conducting wire with a resin and color-coding them. For example, a white electric wire 2a and a red electric wire 2b make a pair. When the display unit 8 lays such electric wires 2a and 2b on the vehicle panel P, as shown in FIG. 4, in the second route 6b of the electric wire laying route 6, the tip side portion of the white electric wire 2a is displayed. The left side of the connector 3 is instructed to connect the tip side portion of the red electric wire 2b to the right side of the connector 3. Of course, when the electric wires 2a and 2b have a color different from the above (for example, “white”, “blue”, etc.), the display unit 8 is displayed in accordance with the color.

  Next, an example of a method for laying the electric wire 2 on the ceiling panel P will be described.

First, as shown in FIG. 3, a double-sided tape 19 is attached to the electric wire laying path 6. This double-sided tape 19 corresponds to an example of an adhesion means in the present invention. Note that an adhesive may be used as the bonding means. In the drawing, the double-sided tape 19 is stretched in a continuous state, but the present invention is not limited to this, and the double-sided tape 19 may be stuck in an intermittent state. Since the electric wire laying path 6 has a concave groove shape, the location where the double-sided tape 19 should be applied is easy to understand, and it is possible to apply it accurately so as not to protrude from the electric cable laying path 6.

  Next, as shown in FIG. 4, the electric wire 2 is laid in the electric wire laying path 6. About the front end side part of the electric wire 2, it is set as the protrusion part 21 which protruded from the 2nd path | route 6b. In this case, each end of the electric wire 2 is brought into contact with the side surface of the measuring mark portion 7. As a result, the protruding portion 21 can be accurately set to the predetermined length L1. Instead of such a method, the electric wire 2 may be cut at the position of the measuring mark portion 7 after the protruding portion 21 of the electric wire 2 is set longer. On the other hand, the portions other than the protruding portion 21 of the electric wire 2 are adhered to the electric wire laying path 6 by using the double-sided tape 19 applied in advance.

  Thereafter, the connector 3 is connected to the tip of the electric wire 2. Since the electric wires 2a and 2b are arranged in the left and right directions corresponding to the display unit 8 for indicating the electric wire arrangement, the electric wires 2a and 2b are connected to the connector 3 in a state where the connector 3 is set in a predetermined direction (for example, face up). When connected to, these positive and negative polarities are correct. Therefore, it is appropriately prevented that the polarity is wrongly connected.

  As shown in FIG. 5, after connecting the connector 3 to the electric wire 2, the base portion of the protruding portion 21 is bent, and the distal end portion of the connector 3 and the electric wire 2 is passed through the opening 90. Thereby, connection with the room lamp 4 can be achieved. In this case, since the length of the protruding portion 21 is the appropriate length L1 using the measuring mark portion 7, when the connection with the room lamp 4 is attempted, the length is insufficient, or Excessiveness can be avoided appropriately, and the length can be made appropriate with some margin. As understood from this, the position of the measuring mark portion 7 is determined in advance so that the protruding portion 21 of the electric wire 2 has an appropriate length as described above. If the length of the protruding portion 21 is defined using the mark portion 7, the protruding portion 21 can be set to an appropriate length that matches the specification of the automobile without performing particularly difficult work.

  According to the method as described above, by laying the electric wire 2 directly on the ceiling panel P, the production of the wire harness H and the assembly of the wire harness H to the ceiling panel P can be performed simultaneously. In addition, as described above, the work of attaching the electric wire 2 to the electric cable laying path 6, the operation of connecting the electric wire 2 and the connector 3 so as not to make a mistake in polarity, and the operation of attaching the double-sided tape 19, and the room A series of operations such as the operation of connecting the electric wire 2 to the lamp 4 can be performed easily and appropriately, and the workability is good. In addition, since the electric wire laying path 6, the measuring mark portion 7, and the display portion 8 are integrally formed with the vehicle panel P, the entire vehicle panel P can be easily manufactured. For example, there is no inconvenience of providing the portion using a printing technique.

The present invention is not limited to the contents of the embodiment. The specific configuration of each part of the vehicle panel according to the present invention can be variously modified within the range intended by the present invention .

In the above embodiment, the case where electrical wiring to a room lamp is performed as an example has been described for ease of understanding, but a plurality of lamps may be attached to the ceiling panel. However, it goes without saying that the present invention can be applied.
The electrical component referred to in the present invention is not limited to a room lamp. Other lamps such as a map lamp are included, and other electric devices such as a motor are also included. The vehicle panel referred to in the present invention is not limited to a ceiling panel but is a concept including a door panel, for example.

  The wire laying path, the measuring mark part, and the display part indicating the electric wire arrangement only have to be integrally formed on the vehicle panel as a three-dimensional part. For example, the measuring mark part is replaced with a convex shape. It may be formed in a concave shape. The electric wire laying path may be one in which a plurality of convex portions are formed on the upper surface of the vehicle panel. The display unit indicating the electric wire arrangement may be displayed using, for example, a symbol instead of the electric wire color.
