Abstract: A wiring harness arranging construction is provided to arrange a wiring harness in a position more toward a passenger compartment than a hinge and a weatherstrip. The construction includes a container casing 10 with a space 10p for accommodating a looped harness, an insertion opening 10f and a withdrawal opening 10g for the harness which are opposed to each other, and a harness fixing portion 10h projecting from the outer surface of the insertion opening 10f. After being inserted through the insertion opening 10f and wound around a windup spring 30 inside the casing 10, the wiring harness is withdrawn through the withdrawal opening 10g. The container casing 10 is secured to either one of a door and a body, and the wiring harness withdrawn from the container casing 10 is extended to the other of the door and the body and secured thereto by a clamp.

Abstract: A serial data communication device of an air conditioner including: an outdoor microprocessor having data transmitting/receiving terminals which transmit/receive a predetermined data; an indoor microprocessor having data transmitting/receiving terminals which transmit/receive data to/from the outdoor microprocessor; a rectification part for converting an alternating current power to a predetermined level of a direct current power to thereby supply the direct current power to the indoor/outdoor microprocessors; an outdoor interface part connected between the data transmitting terminal of the outdoor microprocessor and a direct power output terminal of the rectification part, for isolating the rectification part and the outdoor microprocessor through a first insulation switching part and simultaneously for constituting a first communication line; and an indoor interface part for isolating the rectification part and the indoor microprocessor through a second insulation switching part and simultaneously for const

Abstract: To provide an electrical connection box which can easily respond to a change in the circuit construction among different types of vehicles and among different grades of the same type of vehicles, and can be generally used, an internal circuitry of an electrical connection box is divided into a common circuitry 1 and a special circuitry 2. A conductive layer on which the common circuitry 1 is formed and another conductive layer on which the special circuitry 2 is formed are arranged one over the other at different levels in a casing of the electrical connection box. The common circuitry 1 comprises flat busbars 10, whereas the special circuitry 2 preferably comprises a wire, longitudinal busbars 20, or a flat circuit 25 such as a flexible printed circuit (FPC) or a printed circuit board (PCB). The common circuitry 1 and the special circuitry 2 may alternatively be formed of the same types of conductors or circuit members.
