Abstract
A plug-in unit-mounting structure which makes it possible to efficiently mount plug-in units having different sizes in all slots. PIUs of printed board type which are different in size are mounted using respective mounting frames associated therewith. Box-shaped PIUs are also mounted using respective mounting frame associated therewith. However, no guide rail is provided on the metal shelf per se, for guiding each PIU for mounting the same therein.
Claims13
A plug-in unit-mounting structure for mounting plug-in units each having various circuit packages mounted on a printed board thereof, the structure comprising:
- a shelf comprising a back wiring board, and connectors and guide pins disposed separately on said back wiring board, the connectors being located for engagement with the plug-in units;
- and
- a mounting frame, removably fixed to said shelf before receiving any plug-in units, that receives at least one plug-in unit in a state in which the plug-in unit is fitted to an associated one of said connectors, the mounting frame including:
- a vertical frame part having upper and lower ends and a guide hole for positioning said mounting frame in said shelf, such that said guide hole is engaged with one of the guide pins disposed on said back wiring board;
- upper and lower frame parts respectively fixed to the upper and lower ends of the vertical frame part;
- and
- guide rails which are provided on the upper and lower frame parts and have a length based on a size of the plug-in unit.
An electronic apparatus comprising:
- a shelf comprising a back wiring board, and connectors and guide pins disposed separately on said back wiring board;
- a mounting frame removably fixed to said shelf before receiving any plug-in units, the mounting frame including:
- a vertical frame part having upper and lower ends and a guide hole for positioning said mounting frame in said shelf, such that said guide hole is engaged with one of the guide pins disposed on said back wiring board;
- and
- upper and lower frame parts respectively fixed to the upper and lower ends of the vertical frame part;
- guide rails provided on the upper and lower frame parts and having a length based on a size of a plug-in unit;
- and
- at least one plug-in unit that is mounted on said mounting frame and has a connector configured to be inserted and removed to and from one of the connectors provided on said back wiring board of said shelf.
