[0001]
[Industrial application fields]
The present invention relates to a structure of a door for an automobile, and more particularly, to an electrical component attached to the door and a structure for assembling a wire harness for a door connected thereto.
[0002]
[Prior art]
A door for an automobile is generally constituted by a door frame outside the vehicle and a cover plate inside the vehicle (hereinafter referred to as “door trim”). A power window motor, a door locking solenoid, and the like are attached to the door frame, and a number of switches such as a trunk open switch and a power window switch are attached to the door trim.
As an example of this type of automobile door structure that uses a mounting plate to which a door wire harness is fixed, the wiring work associated with door assembly is facilitated, for example, as disclosed in JP-A-61-51706. This will be described with reference to FIG.
[0003]
FIG. 16 is an exploded perspective view of a conventional automobile door structure.
The flat door wire harness W integrated in advance is fixed to the mounting plate X with an adhesive tape or the like. In the door wire harness W, the main connector 1 and the connectors 7 and 9 of the branch lines 3 and 5 are fixed to one side of the mounting plate X toward the door frame A side. Further, on the other surface of the mounting plate X, the connectors 15 and 17 of the branch lines 11 and 13 are fixed toward the door trim B side.
[0004]
A connector 21 of a cowl side harness 19 from a vehicle body, a connector 25 of a power window motor 23, and a connector 29 of an automatic door locking solenoid 27 are fixed to the door frame A at predetermined positions. On the other hand, the connector 33 of the trunk open switch 31 and the connector 37 of the power window switch 35 are fixed at predetermined positions on the rear surface of the door trim B.
[0005]
Thus, in the conventional automobile door structure in which each element is assembled in advance at a predetermined position, first, the mounting plate X is fixed to the door frame A with an appropriate latch or the like, and at the same time, the connector 1 21, connectors 7 and 25, and connectors 9 and 29. Next, the door trim B is attached to the mounting plate X to which the door frame A is fixed, and the connectors 15 and 33 and the connectors 17 and 37 are joined.
According to such a conventional automobile door structure, the door wire harness W can be easily arranged in a narrow space in the door, and the connector of the electrical component is coupled simultaneously with the assembly of the door trim B. We were able to.
[0006]
[Problems to be solved by the invention]
However, in the conventional door structure for automobiles, the connectors 21, 25, 29 on the door frame A side, the connectors 1, 7, 9 on the placement plate X side, and the placement plate X side are arranged via the placement plate X. Since the connectors 15 and 17 and the connectors 33 and 37 on the door trim B side are coupled to each other at one time, considerable accuracy is required for positioning of these connectors. In addition, since the connector to be coupled is on the back side of the mounting plate X, blind work is unavoidable, and there is a risk of causing poor contact. In addition, since a large number of connectors must be coupled simultaneously, the insertion force increases, and in combination with the aforementioned blind work, a great amount of labor and time are required, resulting in a reduction in workability.
The present invention has been made in view of the above circumstances, and provides a door structure for an automobile in which a door frame and a door trim can be easily attached with a small force and electrical connection between an electrical component and a door wire harness is ensured. Therefore, the object is to improve workability and electrical reliability.
[0007]
[Means for Solving the Problems]

The opening window formed in the door frame, while fixed to the door frame by positioning the follower of the electrical component to the opening window, to fix the driving part of the electrical component to said cover plate, the vehicle body also fixing a door wire harness connected to the side of the wire harness, the electrical wiring of the driving portion release incapable permanently connected to the door wire harness, so that the driven portion is driven by the drive unit The cover plate is attached to the door frame in a state where the driven portion and the drive portion are engaged.
Further, in the automobile door structure, the conductors of the electric wiring of the drive unit and the wire harness for the door are permanently connected so as not to be released by any one of pressure welding, pressure bonding, or high-temperature soluble adhesive. Further, the electrical component is a power window and a door lock, the driven portion is a gear portion of the power window and a link portion of the door lock, the drive portion is a motor of the power window, and the door lock. It is a solenoid.
[0008]
[Action]
The assembly of the door frame and the cover plate is performed only by the engagement of the driven portion and the drive portion in the electrical component, and at the same time, a large insertion force for connecting a large number of connectors is not necessary. In addition, the electrical wiring of the electrical component driving unit is connected to the door wire harness in advance, so that the connecting work between the connectors is not required when the door frame and the cover plate are assembled. And the electric wiring of a drive part is electrically connected permanently, and it will not be in the unstable contact state which enabled cancellation | release, and a connection state will become reliable.
