Latest Patents

One of Hiroaki Arai's latest patents is a hook and method for separating wire harnesses. This invention features a hook that comprises a pair of hook bodies, a pair of hook portions, a movable pressing portion, an operating portion, and a link unit. The hook bodies are formed of two plates that are disposed apart from each other. The hook portions are integrally fixed to the lower ends of the hook bodies. The movable pressing portion is rotatably supported between the hook portions, while the operating portion is subject to a tension load from a hoist. The link unit connects the movable pressing portion to the operating portion. When the operating portion is pulled upward, the movable pressing portion presses a wire harness against the hook portion, enhancing its functionality.

Another significant patent is a detachable attachment structure and electric connection box. This invention features a case main body with an attachment bracket that has a screw hole. The attachment bracket is designed with a slit that communicates with the screw hole and extends radially outward. When the wiring harness is pulled or twisted during the recovery of the case main body, the axial portion of a securing bolt expands the slit, allowing the attachment bracket to detach from the securing bolt. A taper portion is formed at the entrance side of the slit to guide the penetration of the securing bolt.
