초록 ▼

A unitary, permanently-locked, strain-relief bushing and a tool for applying same in an aperture in a support panel. The bushing comprises two generally concave, complementary portions interconnected by a flexible web. Each complementary portion comprises a shank segment having an especially configured shouldered end and a grip segment frangibly secured thereto axially extending from the shouldered end. The tool for applying the bushing into the aperture comprises an open-sided barrel, a plunger within the barrel and an especially configured mounting recess at the front end of the barrel. The mounting recess firmly receives the shank shouldered ends when the complementary portions are folded, concave portion to concave portion permitting an electric conductor or the like to be received in the bore thus defined by the complementary portions. The shank segments are inserted into the aperture whereupon the plunger is actuated to contact the front end of the grip segments and sever the grip segments from the shank segments. Further travel of the plunger forces the grip segments within the shank segments and permanently locks the conductor within the bushing and the bushing within the support panel.

대표청구항 ▼

A one-piece, molded strain-relief bushing for holding an electric conductor fixed relative to an aperture in a support panel through which the conductor extends and adapted to be applied to and permanently locked in said aperture by means of a tool, said bushing comprising: first and second complementary portions and a flexible web portion securing said first portion to said second portion and permitting said portions to be folded into face-to-face relationship; each complementary portion including a grip block segment having a generally cylindrical exterior surface and a shank segment having a generally cylindrical interior surface, said grip block segment axially aligned with said shank segment and frangibly secured thereto at an end thereof; cam means on the external surface of said shank segment to secure said shank segment within said aperture; and locking means to permanently secure (a) said shank segments within said aperture when said bushing is inserted therein, (b) said grip block segments within said shank segments when said grip block segments are telescopically received within said shank segments, and (c) said conductor within said grip block segments when said grip block segments are folded about said conductor and are telescopically received within said shank segments, said locking means including: aligning means to assure a proper predetermined position of said grip block segments within said shank segments when said bushing is locked in said aperture by said tool; said interior surface of each shank segment having an annular rib adjacent said end to which said grip block segment is frangibly secured, said interior surface further including a generally cylindrical portion tapering inwardly in a direction from said annular rib toward the end of said shank segment oppositely disposed from said grip block segment and said interior surface defining a recess disposed between said annular rib and said generally cylindrical portion.
