Abstract

Two protective molded plastic hood embodiments are disclosed that are particularly adapted for use in securing multi-conductor cables to connector plugs of the type typically having one or more arrays of terminals of either the soldered or solderless type associated therewith. Each plastic hood, by having a pressure pad integrally connected to a pressure pad-receiving hood extension formed as an integral rearward portion of the main body of the hood, advantageously allows the composite hood not only to be of one-piece construction, but allows the pressure pad to be key-way guided in a telescopic manner into the hood extension. This insures that reliable, diametrically opposed clamping forces, provided by a cable tie, will always be imparted against a section of cable when positioned between the pad and hood extension, regardless of the diameter of the cable (or cables). In addition, cooperative cable engaging ribs of the pressure pad and hood significantly augment cable strain-relief otherwise effected by only the cable tie-initiated clamping force.

As also realized in accordance with one preferred embodiment, the pressure pad, as distinguished from the hood extension, is adapted to nest the head of the cable tie therewithin, such that the height of the hood extension may be at the same elevation as the main body portion of the hood and, thereby, minimize the height of the composite assembly. Finally, with both of the disclosed hood embodiments being of one-piece molded plastic construction, and being adapted to effect a sliding snap-on type of locked securement with an associated connector plug, no auxiliary fastening members are required.
