Abstract

PURPOSE:To allow easy repeated disconnection of a connector in a short time by splitting a nut into split nuts and providing a mechanism to engage or disengage the split nuts with/from drive screws. CONSTITUTION:First, sliders 2, 2' are opened. If the sliders are closed, locking keys 9, 9' are pushed inside toward the center axis to unlock the sliders 2, 2'. When unlocked, the slider 2 is in a naturally opened condition. The sliders 2, 2' are inserted into outside rails 64, 64' on both sides of a connector. At this time, as split nuts 28, 28' are not engaged with drive screws, the drive screws are moved to an arrow G. Next, the sliders 2, 2' are closed by pushing the sliders 2, 2' to an arrow F and pulling a handle 18 to an arrow G, and held at the positions. On the other hand, when the fitted connector is disconnected, the sliders 2, 2' are replaced to do the same way as the above.
