Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a connector such as a wire harness routed on a vehicle.

[0002]

2. Description of the Related Art Conventionally, wire harnesses for various electric parts mounted on a vehicle are inserted into a hollow portion formed in a vehicle body, and only a connector connected to the electric parts is led out from an opening to form an electric part or the like. Connection to a connector or the like of another wire harness is generally performed.

Recently, for example, while a connector of an electric component has been fixed to a vehicle body, a wire harness has been integrally provided on an interior panel (interior material) or the like, and the connector has been fixedly held in a connectable state. It has been considered that a connector of an electrical component and a connector of a wire harness are fitted to each other by attaching a panel to a vehicle body in a fixed positional relationship. According to this, the work of arranging the wire harness and the work of connecting the connectors can be performed simultaneously with the mounting of the interior panel, and the working efficiency can be significantly improved.

[0004]

By the way, in the above case, if the connectors on the interior panel side and the vehicle body side are completely fixed, it is impossible to connect the connectors when there is an error in the mounting position of each connector. Or the connector housing may be damaged.

[0005] Therefore, one of the connectors is housed and attached to a holder which houses the connector in an elastically displaceable state, whereby the connector can be displaced in a direction orthogonal to the connector connection direction or the like, and the connector is displaced in the above-described manner. It is preferable to be able to absorb an error in the mounting position and the like.

However, when it is necessary to hold a large number of connectors, if each connector is housed in a holder and attached, the number of parts increases, which hinders cost reduction. There is naturally a limit to consolidating connectors.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem. A wire harness or the like is integrally provided in an interior material of a vehicle, and a connector such as a wire harness is attached to the interior material when the interior material is attached to a mounting portion. It is an object of the present invention to provide a connector mounting structure capable of appropriately connecting connectors with an inexpensive structure in a wiring structure configured to be connected to a mating connector fixed to a mounting portion.

[0008]

According to the present invention, a connector is mounted on an interior material of a vehicle.
In a wiring structure configured so that the connector is connected to a mating connector of the attached portion with the attachment of the interior material to the attached portion, the connector is attached to the interior material in a direction orthogonal to the connector connection direction. A holding portion for displaceably holding the connector is provided by integral molding, and the connector is attached to the holding portion.

According to this structure, the connector can be displaceably held only by directly setting the connector on the holding portion of the interior material. Therefore, a dedicated holder as in the related art is not required, and the number of components can be reduced.

In particular, a cylindrical portion protruding in the connector connection direction on the surface of the interior material and a plurality of spring pieces protruding toward the center on the inner surface of the cylindrical portion are provided. When the holding portion is configured so that each spring piece engages with the connector and supports the connector from the periphery by interposing the connector in the connector (Claim 2), the connector is provided in accordance with the elastic deformation of the spring piece. Can be displaceably held.

Further, if a cylindrical shield member made of a conductor is fitted inside the cylindrical portion (claim 3), the external electrostatic or magnetic influence on the connector can be cut off. it can.

The connectors 34 and 36 are attached to the door trim 14 in a state where the connectors 34 and 36 are respectively set in a pair of left and right connector holding portions 30 integrally formed with the door trim 14. By setting the connectors 34 and 36 in the connector holding section 30 in this manner, each connector 3
The displacement in the direction orthogonal to the connector connection direction of the connector 4, 36 and the appropriate inclination with respect to the connector connection direction are possible.

That is, as shown in FIGS. 1 and 2, the door trim 14 has a pair of left and right hollow protrusions each having a rectangular cross section and opening toward the rear of the vehicle corresponding to the positions of the connectors 22 and 24 of the main body 12. A (cylindrical portion) 40 is provided, and four spring pieces 42 extending from the respective component walls toward the center are formed inside the hollow protrusion 40. Then, the connectors 34 and 36 are set in the hollow projections 40. Specifically, the connectors 34 and 36 are pushed into the hollow projections 40 in a state in which the connectors 34 and 36 are directed rearward of the vehicle. As shown in (1), the tip of each spring piece 42 protrudes into a groove 42 formed on the side surface of each connector 34, 36, and each connector 34, 36 is supported by the spring piece 42.
Each of the connectors 34 and 36 is displaced in a direction orthogonal to the connector connection direction in accordance with the bending deformation of each spring piece 42, and can be appropriately tilted with respect to the connector connection direction.

As shown in FIG. 1, the hollow projection 40 has a slit 43 at a corner thereof.
An electric wire 38 connecting the connectors 34 and 36 to each other is released through the slit 43.

According to the back door 10 configured as described above, when the door trim 14 is attached to the main body 12, the connector housings of the connectors 22 and 24 of the main body 12 and the connectors 34 and 36 of the door trim 14 are accordingly attached. The main body 12 and the door trim 14 are fitted with the connector housing.

Generally, the door trim 14 is made of PP.
(Polypropylene) and other materials
The precision at the time of molding is lower than that of a connector or the like made of a material having excellent dimensional stability such as T (polybutylene terephthalate). Therefore, when the connector holding portion 30 is integrally molded with the door trim 14, the hollow protrusion 40 and the like are formed. There is a concern that an error may occur in the position and affect the connection between the connectors. However, the connector holding unit 30
Since it is a part for holding the connectors 34 and 36 in a displaceable manner, high precision is not required for molding. For example, even if there is a slight error in the position of the hollow projection 40, the connector 34, 36 This error is absorbed by the displacement. Therefore, even if the connector holding portion 30 is integrally molded with the door trim 14, the connection between the connectors is hardly affected.

As shown in this drawing, each of the connectors 34 and 36 is made of a metal conductor.
Is surrounded, the external electrostatic or magnetic influence is cut off, and a shielding effect for the connectors 34 and 36 is exhibited. Therefore, without using an expensive shielded connector, in other words, using a general connector, it is possible to suppress the influence of static electricity or the like at the connector connection portion, thereby providing a wiring structure resistant to static electricity or the like at low cost. It becomes possible.

Further, the structure of the connector holding portion 30, that is, the specific shape of the spring piece 42 formed in the hollow projection 40, the position of the slit 43, and the like are not limited to those shown in the drawings. It can be changed appropriately according to the shape and the wiring structure.
