Abstract
A telecommunications apparatus 10 includes a sub-rack unit 15 and a plurality of plug-in units inserted from a front side of the sub-rack unit 15 in a Y1 direction and mounted in the sub-rack unit 15. The plug-in unit 16 includes a plug-in unit main body and an aluminum case 41 that covers so as to envelope the plug-in unit main body. An intermediate guide rail member 22 is inserted from the front of the sub-rack unit 15 and mounted by tightening a lock bolt member similarly inserted from the front of the sub-rack unit 13.
Claims21
A telecommunications apparatus comprising a sub-rack unit having a back wiring board and a guide rail portion and a plurality of plug-in units inserted and loaded into the sub-rack unit from a front surface thereof along the guide rail portion, the plug-in comprising:
- a metallic front member;
- a printed board fixedly mounted at one edge on the metallic front member and having, at a leading edge in a direction of insertion, a connector designed to be connected to the back wiring board when loaded;
- and
- a metallic case that envelopes the printed board and has an opening on a leading edge in a direction of insertion that exposes the connector,
- the plug-in unit configured so that an edge of the opening on the leading edge in the direction of insertion of the metal case contacts the sub-rack unit in a state in which the plug-in unit is mounted in the sub-rack unit;
- wherein at least one intermediate guide rail member is provided so as to divide the internal space of the sub-rack unit and provide a guide rail portion at a predetermined intermediate position of the sub-rack unit along which the plug-in unit is inserted into the sub-rack unit.
A telecommunications apparatus comprising a sub-rack unit having a back wiring board and a guide rail portion and a plurality of plug-in units inserted and loaded into the sub-rack unit from a front surface thereof along the guide rail portion,
- the sub-rack unit configured so as to have a back wiring board frame plate having ribs provided on a front of the back wiring board,
- the plug-in unit comprising:
- a metallic front member;
- a printed board fixedly mounted at one edge on the metallic front member and having, at a leading edge in a direction of insertion, a connector designed to be connected to the back wiring board when loaded;
- and
- a metallic case that envelopes the printed board and has an opening on a leading edge in a direction of insertion that exposes the connector,
- the plug-in unit configured so that an entire peripheral edge of the opening on the leading edge in the direction of insertion of the metallic case contacts the back wiring board frame plate ribs in a state in which the plug-in unit is mounted in the sub-rack unit;
- wherein at least one intermediate guide rail member is provided so as to divide the internal space of the sub-rack unit and provide a guide rail portion at a predetermined intermediate position of the sub-rack unit along which the plug-in unit is inserted into the sub-rack unit.
A plug-in unit that is inserted and mounted in a sub-rack unit having a back wiring board and a guide rail, the plug-in unit comprising:
- a metallic front member;
- a printed board fixedly mounted on the metallic front member and having a connector on an end in a direction of insertion such that, when inserted, the connector is connected to the back wiring board;
- and
- a metallic case having an opening that exposes the connector on the end in the insertion direction and that covers so as to envelope the printed board;
- wherein the plug-in unit has a size selected from a plurality of ones corresponding to a space in the sub-rack unit, said space being defined by an intermediate guide rail member which provides a guide rail portion at a predetermined internal position of the sub-rack unit along which the plug-in unit is inserted into the sub-rack unit.
