ABSTRACT:
A line cord strain relief attachment assembly facilitates insertion and replacement of a two conductor line cord terminated by relatively small geometry terminal lug connectors, rather than a larger modular style multiconductor connector, such as an RJ-45 plug. The line cord strain relief attachment assembly includes a generally cylindrically configured strain relief element, made of a suitable flexible and waterproof material and having a flange spaced apart from one end of the element. The strain relief element has a diameter proximate to that of a generally circular aperture in a rear wall of the test set. Adjacent to the one end of the strain relief element its cross-section is reduced to form a sloped recess region. A line cord retention wedge has a slot which conforms with the recess region of the strain relief element. The slot is bounded by opposing ramp-configured walls, that are sloped to conform with the sloped surface of the tapered recess region of the strain relief element. As a result, when the line cord retention wedge is inserted into the test set and engages the sloped recess region of the strain relief element, the strain relief element is drawn into the aperture of the test set, bringing the flange of the strain relief element into sealing engagement with the external surface of the test set.
