5 'integrally has a fixing clip 167 at the tip of a guide pin 166 for positioning. The exposed conductors of the terminal portions 150 and 158 of each of the wire harnesses 115 and 116 function as surface contact terminals by applying conductive plating. The female connector housing 159 and the terminal portion 158 constitute a female connector 168.

As shown in FIGS. 31 to 32, by attaching the pillar trim 118 to the molded ceiling 117 (or by attaching the molded ceiling 117 to the pillar trim 118), both connectors 157 and 168 are fitted together, and both wire harnesses 115 and 116 is connected. The guide pins 165, 165 'with clips are engaged with the engagement holes 155, 155', and the two end portions 150, 158 are securely aligned. Further, the spring piece 164 is connected to the terminal 150 on the side of the convex 152.
And the terminal 158 is bent by the repulsive force of the spring piece 164.
Presses into contact with the terminal unit 150, and reliable electrical connection is performed. The clip 167 is engaged with the upper surface of the molded ceiling 117 through the engagement holes 155 and 155 '. As a result, the connectors 157 and 168 are securely locked. Both terminals 15
The non-connection portions of 0 and 158 are separated by a boss 154.

According to the present embodiment, the wire harness 11
By dividing 5, 116 into a roof part and a pillar part and integrally forming the molded bodies 117, 118, the number of steps for assembling the wire harness to the body is reduced. Further, the number of components of the exterior parts (clamps, protectors, etc.) of the wire harness is reduced. In addition, since the FFC (flexible flat circuit) 115 is directly circuitized inside the roof unit 120, the number of components such as connectors of the roof unit 120 is reduced. In addition, the use of the reflector 129 serving as a lamp socket and a contact also simplifies the structure of the FFC contact portion and reduces the number of FFC contacts inside the roof unit 120. In addition, the connection structure of the connectors 157, 168 of both the wire harnesses 115, 116 is simplified, and reliable electrical connection is obtained.

[0057]

As described above, according to the first aspect of the present invention, since the bent portion between the roof and the pillar does not occur in the wire harness, the roof wire harness and the pillar wire harness can be automatically wired. Machines can be routed independently and linearly, thereby increasing the efficiency of wiring work. According to the second aspect, since the connectors are temporarily fixed to each other, the work of tightening the fixing screws is facilitated, and the number of screw components is reduced by using the fixing screws together. According to the third and fifth aspects, the connection work of the wire harness is made more efficient by the pressure welding. According to the fourth and sixth aspects, it is possible to support connection of optional parts for each grade by the control board without changing the specification of the roof wire harness. Thereby, the part number of the roof wire harness is reduced.

According to the seventh aspect, the harness circuit can be smoothly and reliably selected by sliding the slide switch corresponding to the flat wire harness. Also,
According to the eighth aspect, the control board can be easily and reliably connected to the flat wire harness. According to the ninth and eleventh aspects, the roof wire harness and the pillar wire harness can be easily and reliably connected to the flat wire harness. Further, according to the tenth aspect, since the reflector also serves as the lamp socket and the contact, the number of components in the lamp unit is reduced, and the structure of the lamp unit is simplified and the cost is reduced. According to claim 11,
The connector is positioned and fixed by the guide pin with clip, and the number of components is reduced.
