Abstract: A flexible circuit board inspecting apparatus for conducting an inspection on a flexible circuit board includes a transport path and an inspection part mechanism. The transport path is configured to successively transport the flexible circuit board having a plurality of unit circuit boards arranged thereon. The inspection part mechanism is configured to bring and distance a jig for inspecting the flexible circuit board transported on the transport path close to and from the flexible circuit board. The transport path includes a longitudinal transport portion for transporting the flexible circuit board in a downward vertical direction. The inspection part mechanism moves the jig in a direction perpendicular to the flexible circuit board transported on the longitudinal transport portion to bring and distance the jig close to and from the flexible circuit board.

Abstract: An insulation inspection technique for allowing the occurrence of sparks to be detected more satisfactorily and allowing a board in which sparks have occurred to be more satisfactorily detected as being detective is provided. An insulation inspection apparatus detects a voltage induced between insulation inspection target wiring patterns by the application of a voltage during a time period from the start of the voltage application between the insulation inspection target wiring patterns to a predetermined time when the voltage between the insulation inspection target wiring patterns has stabilized. When a voltage drop due to sparks occurring between the insulation inspection target wiring patterns is detected during the time period, the board to be inspected is determined to be defective. In particular, supply current during the time period is set in accordance with the number of inspection points of an upstream wiring pattern of the insulation inspection target wiring patterns.

Abstract: A contact terminal includes a tubular body and a first conductor. The tubular body has an end-side cutout provided in a shape cut out from one axial-direction end surface toward an other axial-direction side at one axial-direction end portion of the tubular body, a hole that is open at the one axial-direction end portion, and a pair of arms interposed between the end-side cutout and the hole. The first conductor includes a first insertion including an inclined portion having an outside diameter gradually increased toward one axial-direction side, and a first straight portion connected to the one axial-direction side of the inclined portion and having an outside diameter constant along the axial direction. The outside diameter of the first straight portion is larger than an inside diameter of the tubular body. The first straight portion is configured to be in contact with the pair of arms.
