A structure for introducing an optical cable into a communication apparatus includes an adapter (3) to be affixed to a side wall (21) forming a part of the casing (2) of the apparatus. A case (4) is fitted in a bore axially extending throughout the center of the adapter (3). A ring nut assembly (5) holds an optical cable (6) at its center and is connected to the adapter (3) in such a manner as to cover the case (4). The cable (6) includes a tension merber (61) introduced into the casing (2) via the case (4) and adapter (3) and affixed by a tension member affixing portion (46) disposed in the casing (2). In this condition, the cable (6) is firmly affixed by the ring nut assembly (5) and tension member affixing portion (46), i.e., at two points. The fibers of the cable (6) are therefore free from breakage ascribable to a twisting force or a pulling force. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a new optical cable introducing structure which is small size, desirable in water-proof, maintenance and general-purpose applicability, and frees an optical cable from damage, and an optical cable connecting method for the same.
It is another object of the present invention to provide a new optical cable introducing structure capable of adapting itself to optical cables having different diameters while facilitating the replacement of such optical cables, and an optical cable connecting method for the same.
It is still another object of the present invention to provide a new optical cable introducing structure surely preventing an optical cable from being damaged, and an optical cable connecting method for the same.
It is a further object of the present invention to provide a new optical cable introducing structure capable of obviating a dead space existing in the casing of a conventional communication apparatus and promoting the efficient use of a limited space available in the casing to thereby miniaturize the apparatus, and an optical cable connecting method for the same.
In accordance with the present invention, in a structure for introducing an optical cable into the casing of a communication apparatus, an optical cable is affixed at at least two positions.
In a preferred embodiment, the cable is affixed at at least two positions outside of the casing of the apparatus.
The above cable is affixed at at least one position by means for affixing the cable itself and at at least another position by means for affixing a tension member included in the cable.
In a preferred embodiment, the structure includes an adapter to be mounted to the casing while holding the cable at its center, a ring nut assembly connected to the adapter while holding the cable at its center, and a case intervening between the ring nut assembly and the adapter.
Specifically, a plurality of cases identical in outside diameter, but different in inside diameter, are prepared and selectively used in accordance with the outside diameter of the cable
