Castellated optical fiber cable retention structure

摘要

A cable retention structure defining a castellated fiber cable clamping surface. The castellated surface has a series of alternating small and large cavities distributed along the axial direction. The small cavities are sized such that when the castellated surface is pressed against the buffer jacket exterior of the fiber cable, the small cavities will be able to clamp the fiber cable jacket within its full dimensional tolerance range. The large cavities are sized to provide sufficient clearance to accommodate the relatively soft material of the cable jacket which cannot be accommodated by the small cavities. The cable jacket is securely held by the retention structure to prevent slipping. Accordingly, fiber cables having buffer jackets with large dimensional variations can still be securely retained by the castellated retention structure in accordance with the present invention.

主权项

1. An optical fiber cable retention structure, comprising a first body comprising a castellated structure for engaging a cable jacket, wherein a sectional profile of the castellated structure comprises alternating valleys and peaks, and wherein the peaks have a substantially flat top surface; and
a second body opposing the first body, wherein when the cable jacket is clamped between the castellated structure of the first body and the second body with opposing surfaces of the first body and second body in mating contact, the peaks of the castellated structure of the first body press on the cable jacket and the valleys of the castellated structure of the first body receive excess material of the cable jacket that flows to the valleys under pressure of the peaks, thereby forming a castellated surface profile corresponding to the castellated structure of the first body, and interlocking the castellated surface profile of the cable jacket to the castellated structure of the first body.
