CONNECTION BOX FOR FIBRE-OPTIC CABLE Russian patent published in 2015 - IPC G02B6/44 

FIELD: electricity.

SUBSTANCE: invention relates to connection box (1) for a fibre-optic cable, which includes at least a housing consisting of two parts with lower part (3) and cover plate (2), besides, inside the housing there located is at least one adjustment device (20) for connection coupling (30) for clamping of plug-in connectors for fibre glass, as well as at least one connection coupling (30) differing by the fact that adjustment device (20) is made in the form of a double frame that includes two first vertical posts (21) and two second vertical posts (22), with that, the first and the second posts (21, 22) are oriented vertically to lower part (3), besides, the second posts (22) in relation to the first posts (21) are located closer to front side (5, 40) of cover plate (2) and lower part (3), with that, connection coupling (30) has a possibility of being optionally fixed in the first or second posts (21, 22), besides, the side of the second posts (22) means front side (V), and the side of the first posts (21) means rear side (R), with that, connection coupling (30) inserted from the front side (V) is fixed in the second posts (22) so that its front part directed towards the front side (5, 40) ends with end surface (40) of lower part (3), with that, a plug-in connector for fibre glass, which is inserted in the front part of connection coupling (30), has a possibility of being removed at closed cover plate (2), with that, connection coupling (30) inserted from rear side (R) of adjustment device (20) is fixed in the first posts (21) so that its front part directed towards front side (5, 40) is located inside adjustment device (20), with that, the plug-in connector for fibre glass, which is inserted in the front part of connection coupling (30), is protected against being pulled out by means of closed cover plate (2).

EFFECT: achieving possible implementation of a connection box, the design of which provides for prevention of undesired removal of a plug-in connector for fibre glass.
