ABSTRACT:
A strain relief device for a multipole electrical plug connector, is constructed for holding a bunch of conductors either axially or at a right angle to its main axis. The device is also simplified in its structure so that the manufacture of its components and their assembly is facilitated. The device has a cap nut with a radially inwardly extending flange, and a housing with a radially outwardly facing circumferential channel. The housing has a through slot in its wall for temporarily and elastically compressing the housing radially inwardly so that the channel may engage the flange of the cap nut which is then locked in place, but rotatable relative to the housing. The flange either directly or indirectly helps compressing a sealing member in the connector proper. A conductor bundle holder includes a bail which can be secured to the housing in several different positions for holding a bundle of conductors either to extend axially or at an angle out of the housing.
