Wire harness joint

摘要

The prior art used a joint box to be connected to wire harnesses within a motorcar. Such a joint box was heavy and bulk. Therefore, a number of such joint boxes could not be located within the motorcar at any position. This became an obstacle when the comfortability in the motorcar is to be improved. The present invention provides a wire harness joint comprising a wiring circuit assembly and an insulation film or insulation films applied to the wiring circuit assembly on one or both sides. The wiring circuit assembly includes a number of flexible flat cables (FFC) disposed separately so that they will not intersect one another. The wiring circuit assembly further includes connections for connecting the tips of a wire harness including a plurality of parallel disposed FFC's to the FFC's of the wiring circuit assembly. Each of the insulation films is formed with windows at positions corresponding to the connections.
