The appearance inspection device inspects an appearance of a crimp terminal by capturing an image of the crimp terminal with a camera while applying illumination light onto the crimp terminal. The device includes an illumination unit for applying illumination light onto a crimp terminal and cameras that capture an image of the crimp terminal. A planar gradation light source having brightness that gradually changes in a predetermined direction from one side on an illumination surface toward another side is provided as the illumination unit. The cameras are disposed such that the gradation light source is reflected on an image obtained by the camera capturing the image of the crimp terminal, as a reflected image on a surface of the crimp terminal.

Appearance inspection device of crimp terminal

A waterproof connector includes a resin housing; a conductor extended from the resin housing, and provided with a recess portion at a portion of a part embedded in the resin housing; and a sealing agent interposed in a gap between the conductor which includes the recess portion and the resin housing.

Waterproof connector and fabricating method therefor

The present invention is to provide an apparatus for coloring an electrical wire to improve a visibility and design of the electrical wire. The apparatus includes a coloring device for ejecting a liquid coloring material to an outer surface of the electrical wire and a sliding device for moving relatively the coloring device in a direction perpendicular to a longitudinal direction of the electrical wire so as to color each whole outer surface of a plurality of coloring regions thereof responsive to a belt-shaped design pattern.

Apparatus and method for coloring electrical wire

A wire coloring apparatus including a roller is provided to prevent drag of a colorant, which is jetted on an electric wire and not dried yet, the guide roller is arranged at a downstream side of a coloring nozzle, which jets a colorant toward a highest point of an outer surface of the electric wire moving along a lengthwise direction thereof, in a moving direction of the electric wire. The guide roller is formed with a pair of tapered surfaces catching and supporting the electric wire and approaching to each other in accordance with nearing to a rotating axis. When a radius Rof the electric wireis 1.2 mm, an angle &#x3b8;formed by the pair of tapered surfaces is designed at least 60 degrees and not more than &#x3b8;degrees.
