Embodiment Construction

[0021] Figure 1 is a schematic illustration of a protective box 10 commonly used in the terminal portion of a telecommunications network - for serving a large number of subscribers from a single point.

[0022] The protective box 10 generally has the form of a cuboid with an inlet face 12 and an outlet face 14 at opposite ends. The entry face 12 has at least one entry hole 16 for passage of fiber optic telecommunication cables.

[0023] There are also additional holes 17 in the inlet face 12 of the protective box. These additional holes 17 are used to enable individual telecommunication cables to enter and exit the protective box.

[0024] Referring to FIG. 2 , means 18 for a sealed connection of telecommunication cables are designed to be housed in access holes 16 formed in the inlet face 12 of the protective box 10 .

[0025] The connection device 18 of the invention comprises in particular a tubular plug 20 and a plurality of tubes 22, wherein each tube 22 is intended to ...

Abstract

The invention relates to a device for the leakproof connection of telecommunication cables (18), comprising a tubular cap (20) which is intended to be housed in an inlet in a telecommunications protection casing and a plurality of tubes (22) which are each intended to receive at least one telecommunication cables (34). According to the invention, the tubes (22) are disposed longitudinally in the cap (20) such as to extend straight through same, and a resin (28) is poured between the tubes (22) such as to ensure that the tubes are retained mechanically in the cap and that the connection device is leakproof.

Description

technical field [0001] The present invention relates to the field of telecommunications in general. More particularly it relates to a device for the sealed connection of telecommunication cables, such as fiber optic cables, for use in protective boxes for distribution lines. Background technique [0002] Fiber optic cables used to construct telecommunication lines are joined by connectors and splices. To protect them from moisture and other environmental agents (oil, acid or other contaminants), cable terminations and connectors are generally placed in sealed protective boxes, which are themselves placed in telecommunications structures ( basements, cabinets, wiring ducts, etc.). [0003] Such protective boxes - generally tubular or parallelepiped in shape - have inlets, which are usually located in two opposite faces. These inlets need to be completely sealed with respect to their own closure means and with respect to their cable inlets. [0004] Furthermore, the cable ...
