Latest Patents

One of Hajime Maejo's latest patents is a wire harness manufacturing system. This system includes a display unit, a wire cutting machine that draws an electric wire from a wire feed reel and cuts it to a predetermined length. The control unit directs the display unit to show a wire laying image and wire work identification information for each electric wire. The wire laying image features multiple wire images depicting the electric wires in their laid state, while the work identification information is displayed near the corresponding wire image. The memory unit stores the wire laying image and work instruction information, which includes the cut length of the electric wire. The control unit then sends this cut length information to the wire cutting machine.

Another notable patent is for a wire harness that consists of a cable with electric wires covered by a sheath. The design ensures that the electric wires are exposed from the end portion of the sheath. It includes a housing that accommodates the exposed electric wires, wire seal members to create a seal between the electric wires and the housing, and a holder with an elastic body. The holder features a cylindrical sheath-side cylinder portion that contacts the outer surface of the sheath and a cylindrical housing-side cylinder portion that contacts the outer surface of the housing. These components are integrally formed, and a first pressing member presses the housing-side cylinder portion toward the housing to secure it.
