Abstract
Abstract A connector housing unit for an electrical connector having a threaded fastener including a bolt and a nut. The bolt is provided in an outer connector housing of the connector housing unit and the nut is provided in an inner connector housing. A tentative fastening device and a tentative stoppage device are provided on the connector housings and located in such positions that the component parts of the tentative fastening device are engaged with each other at the same time as the component parts of the tentative stoppage device are engaged with each other. The bolt can move within a prescribed range in the axial direction of the bolt as the connector housings remain tentatively fastened to each other. Therefore, the threads of the bolt and the nut will not be damaged if the tentatively fastened connector housings are pried relative to each other.
