DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning module for a vehicle provided inside an instrument panel of a vehicle, and more particularly to a vehicle air conditioning module for electrically connecting to an electrical component mounted on a mounting surface of the instrument panel. The present invention relates to a vehicle air conditioning module provided with a connector.

[0002]

2. Description of the Related Art Generally, an air conditioner for a vehicle mounted on an automobile or the like is disposed substantially in the center of an instrument panel and fixed to a vehicle body directly or via a fixing bracket or the like.

A sub-wire harness for an air conditioner is routed and fixed on the surface of an air conditioner for a vehicle, and a servo motor for mode switching, a servo motor for air mixing, an air conditioning control unit, and a floor unit are mounted on the air conditioner for a vehicle. And the like are electrically connected to the electrical components by a connector. Also,
The air conditioner sub-wire harness is provided with a connector for electrically connecting to the vehicle-side wire harness, and is connected to the vehicle-side wire harness connector when or after the air conditioner is mounted on the vehicle. You.

When the vehicle air conditioner is directly fixed inside the instrument panel, the connector of the sub wire harness for the air conditioner is connected to the connector of the wire harness for the instrument panel.

[0005] The instrument panel wire harness is provided with a trunk line routed across both ends of the instrument panel, a branch line branched from the trunk line portion, and a branch line provided with a connector at the tip end. And a part. The main line is fixed to the back of the instrument panel main body, or to a reinforce or air conditioning duct mounted inside the instrument panel. The branch line is used for electrical components such as an air conditioner mounted on the instrument panel, an electrical component control unit, an electrical junction box, or a center cluster panel or an instrument panel mounted on the mounting surface of the instrument panel. Connected.

When the instrument panel wire harness is mounted on the instrument panel, the trunk line is routed inside the instrument panel, and after fixing, the connector provided at the tip of the branch line is connected to the instrument panel. It fits into the electrical connector of the electrical component mounted beforehand inside the panel. At this time, if the branch line is too long to hold the route, the middle of the branch line may be fixed inside the instrument panel. In addition, the connectors connected to electrical components such as the center cluster panel and the instrument panel mounted on the mounting surface of the instrument panel that are not mounted on the instrument panel are mounted on the instrument panel body. It is left unfixed near the opening.

On the other hand, for example, a center cluster panel disposed at the center of the mounting surface of the instrument panel includes:
Electrical components such as an air conditioner operation switch group, an audio device, and an audio device operation switch group are provided, and a connector for an instrument panel wire harness is provided on a back surface thereof. The center cluster panel is fixedly mounted around a mounting opening formed in the center of the mounting surface of the instrument panel.

FIG. 6 is an explanatory view for explaining a conventional mounting method when an electric component is mounted on a mounting surface of an instrument panel.

As shown in FIG. 6A, a wire harness 2 for an instrument panel is provided in the vicinity of a mounting opening 20b formed substantially at the center of a mounting surface 20a of an instrument panel 20.
One connector 22 is left without being fixed.

Next, as shown in FIG. 6B, the connector 22 of the instrument panel wire harness 21 is connected to the mounting surface 20 of the instrument panel 20 through the mounting opening 20b.
It is pulled out to the side a and fitted to a connector 24 provided on an electrical component 23 such as a center cluster panel.

Thereafter, as shown in FIG. 6C, the electric component 23 is fixedly attached to the mounting surface 20a around the mounting opening 20b.

The branch portion of the instrument panel wire harness 21 provided with the connector 22 connected to the connector 24 of the electrical component 23 is pulled out from the mounting opening 20b to the mounting surface 20a side of the instrument panel 20, and the electrical component 23 In order to perform the work of connecting to the connector 24, it is necessary to provide an extra length in advance to the instrument panel wire harness 21.

However, as described above, since the work of mounting the electrical component 23 such as the center cluster panel on the mounting surface 20a of the instrument panel 20 is performed manually, the wire harness 2 for the instrument panel is used.
1 connector 22 with one hand through the mounting opening 20b.
Pull out to the mounting surface 20a side of the instrument panel 20, support the electrical component 23 with the other hand,
Since the two and the 24 had to be fitted together, it was a very laborious and difficult operation.

Further, since it is necessary to provide an extra length in advance at the branch portion of the instrument panel wire harness 21, the extra length of the electric wire causes an increase in cost. In addition, since the extra length is provided, after the electrical component 23 is mounted, the branch line portion comes into contact with other mounted components inside the instrument panel 20, causing abnormal noise, wire harness breakage, and short circuit due to electric wire damage. May occur. If an abnormal noise prevention component, an electric wire protection component, or the like is attached to the branch line portion in order to prevent the occurrence of these inconveniences, the cost increases significantly.

The present invention has been made in order to solve the above-mentioned problem. At the same time as mounting the electrical component on the mounting surface of the instrument panel, the electrical component connecting connector to be connected to the connector of the electrical component is provided. An object of the present invention is to provide a vehicle air-conditioning module that can improve workability and reduce costs by providing the module.

The electrical component connecting connector may be an electromagnetic induction type connector.

According to the vehicle air conditioning module of the present invention,
At the same time as mounting the electrical component on the mounting surface of the instrument panel, the electrical component connection connector is connected to the connector of the electrical component. Further, an instrument panel wire harness having an extra length as in the related art becomes unnecessary.

The electric component D may be configured to transmit electric power, an electric signal, and the like. In this case, since the connectors 4 and 5 are electrically connected even in a non-contact state, it is possible to prevent poor connection between the connectors 4 and 5 due to a dimensional error, an assembly error, or the like.

Further, as shown in FIG.
A power supply connector 8 is provided on the upper surface of the air conditioner. The air conditioner main body side power supply connector 8 and the electrical component connection connector 5 are connected by an air conditioner sub-wire harness 9 fixed to the surface of the air conditioner main body 1 by bonding and fitting.

It is directly connected to the connector 4 of the electrical component D mounted on the mounting surface 3a of the panel 3 via the mounting opening 3b.

Accordingly, since the electrical component D is attached to the mounting surface 3a of the instrument panel 3 and the electrical component connecting connector 5 is connected to the connector 4 of the electrical component D at the same time, the work of connecting the connectors is simplified. The workability is greatly improved.

Further, since a conventional wire harness for an instrument panel having an extra length is unnecessary, cost can be reduced, and there is a problem such as generation of abnormal noise due to the extra length of the wire harness and short-circuit due to damage of the electric wire. This eliminates the need for abnormal noise prevention parts and electric wire protection parts, thereby reducing costs.

The present invention is not limited to the above embodiment, and various changes can be made within the technical scope described in the claims. The present invention is also applied to the case of the electrical component D other than the center cluster panel.
