1. A terminal assembly comprising:
a connector housing having an opening at a first end for receiving a cable, the opening having an inner surface defined by a housing inner diameter; and
a strain relief device having an annular base and a cylindrical portion extending from the annular base, the cylindrical portion having an inner surface having a diameter selected to surround the cable and an outer surface having an outer diameter configured to fit within the opening of the connector housing, the fit between the cylindrical portion of the strain relief device and the inner surface of the connector housing generating a clamping force between the strain relief device and the cable, the strain relief device including a plurality of ribs extending axially along the outer surface of the cylindrical portion, the plurality of ribs configured to deform due to exertion of force by the inner surface of the connector housing on the plurality of ribs generated by inserting the cylindrical portion within the opening of the connector housing.
