A container box for use in a communication apparatus. The container box has a container case defining an internal space; partitions connected to the container case for partitioning the internal space to have at least two accommodating chambers; and a container cover corresponding to each of the at least two accommodating chambers. Each cover is connected to the container case for independently closing and opening the at least two accommodating chambers. Wherein the at least two accommodating chambers each have differing degrees of waterproof level.

Container for use in a communication apparatus having a plurality from one another in waterproof level of independent chambers which are different

In an electronic unit which comprises a heat source, is supported in a casing, and should be kept below an allowable temperature, a movable heat sink is brought into thermal contact with the heat source and an external heat sink of the casing. Preferably, the movable heat sink is movable into and out of the thermal contact with the heat source and is slidably guided by a guide member of the casing. More preferably, a resilient thermal conductive member is interposed between the heat source and the movable heat sink.

Cooling arrangement comprising for a heat source a heat sink movable on an external sink

An attaching arrangement for attaching, to a communications apparatus container box, an optical cable case which includes a case body for accommodating an optical cable and a case end portion attached to the case body. The attaching arrangement includes: a first rotary hinge having a first rotary hinge axis for rotatably attaching the case end portion to the container box around the first rotary hinge axis; and a second rotary hinge having a second rotary hinge axis perpendicular to the first rotary hinge axis for rotatably attaching the case end portion to the container box around the second rotary hinge axis. In a preferred implementation, the attaching arrangement further includes: a slide rail slidably attached to an inner surface of the container box along a direction parallel to the second rotary hinge axis so that the slide rail is slidable from an inside of the container box to an outside of the container box and from the outside of the container box to the inside of the container box. The first and second rotary hinges rotatably attach the case end portion to a forward end of the slide rail in an advancing direction in which the slide rail moves from the inside of the container box to the outside of the container box.
