Title: Good or bad determination of wire harness
Inventor: ITAYA NOBUYUKI
IPC: H01R43/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a high-quality product by restraining a defective product from leaking without being detected in a manufacturing process of a wire harness. SOLUTION: A laser measuring instrument 30 is arranged between a wire transferring mechanism 20 in the upstream of a manufacturing line and a crimping machine 40 in the downstream. The laser measuring instrument 30 measures the outside diameter of a wire (w) throughout its total length by arranging two sets of opposite pairs of projectors and light receivers on the front and back surfaces of a frame 2 vertically erected in two directions perpendicular to each other, by forming holes in the projection width for passing the wire (w) to pass it and by projecting light during its passing.  When the outside diameter of the wire (w) is different by its tolerance or more from a normal one, it is determined that there is a defective factor such as a depression and a crack on its surface, and the looseness of a core resulting in the breakage of the core or a contact failure has occurred inside the sheath. By virtue of the determination, a high-quality product can be provided without omission of its inspection as compared with the case in which quality determination of press contact is carried out only by the measurement of the press contact height and a continuity test.

CONSTITUTION:The acceleration Gv of wheels is calculated from the respective average wheel velocities of a vehicle having been input into a speed change stage control part 26a, and then the difference G between this Gv and the vehicle body acceleration G detected by an acceleration sensor 22 is obtained. By comparing this  G with a predetermined threshold valve  G, if  G> Gs, it is judged that there is slip, and further the vehicle body acceleration G is made to be the maximum frictional coefficient mumax of a road, which is compared with the criterion value mus for a low mu road surface, and if mumax<mus, it is judged that the road surface is to be a low mu road surface. On the other hand, the speed change stage signal P comforming to the present operating condition is corrected by the correcting signals or the like from a low mu road surface judging means 35, and a speed change stage control signal 29 is output.
