发明名称 Splice case with tight sealing grommet
摘要 A sealing grommet (40), used in cable splice cases (10) for connecting multiconductor telecommunication cables (100, 120), comprises a unitary elastomeric body with cable receiving passageways (50, 70). Each passageway is defined by an interior sidewall (52, 72) from which a plurality of longitudinally spaced circumferential ridges (54, 74) extend. For a substantial portion of its circumference, each ridge has an axis of projection (60, 82) which forms an oblique angle ( alpha , beta ) with respect to the axis (58, 80) of the passageway and is sufficiently elongated in longitudinal cross section so as to be capable of flexing with respect to the axis of projection during cable insertion and enlarging its opening diameter (DR, DSR) to accommodate and form a radial seal about a cable being inserted.
