ABSTRACT:
The invention relates to an improved strain relief adapted for mounting within a connector housing so as to protect a terminated cable assembled thereto from damage as a result of flexure of the cable relative to the housing. The strain relief including a sleeve having a proximal portion, a distal portion, and a central lumen disposed therebetween. The sleeve being adapted to slidingly receive the cable within the central lumen. The distal portion of the strain relief includes a substantially rigid tube that has a pair of shoulders which project radially-outwardly from an external surface of the distal portion in diametrically-opposed relation to one another. An annular shoulder is positioned in spaced relation to the pair of shoulders and projects radially-outwardly from the external surface of the strain relief. A recess is defined between the pair of shoulders and the annular shoulder. The strain relief structure is adapted to be assembled to a correspondingly shaped receptacle portion of a connector housing.
