A modular plug attaching and detaching tool includes a first holder configured to accommodate a plurality of modular plugs in an aligned state and a second holder configured to press unlocking claws of the plurality of modular plugs when the second holder is attached to the first holder. The first holder includes an engagement groove extending in an inserting direction of the modular plug. The second holder includes an engagement part configured to engage with the engagement groove of the first holder by being moved in the inserting direction.

Tool and method for attaching and detaching modular plugs

A communication apparatus which occupies small space and yet can be connected with numerous external cables and which permits a cooling arrangement to be constructed at low cost. An information processing device constituting the communication apparatus has external cable connection ports provided on both top and bottom surfaces thereof, and thus, more external cables can be connected than in the case of connecting the cables to the side surfaces. Also, the external cables connected to the ports are guided along the top and bottom surfaces toward the front of the communication apparatus with their heights restricted by external cable covers and, therefore, do not occupy substantial space above and below the device. Further, since the external cables are connected to the top and bottom surfaces, the front and rear surfaces of the device have spare space, making it possible to construct a ventilation arrangement such as vent holes and fans.

A cooling structure for electronic equipment including a plurality of electronic devices superposed on each other, each of the electronic devices having a lower part where an air ventilation part configured to ventilate air so as to cool the electronic device is provided, the cooling structure includes an air intake and exhaust hole forming part which is formed at an upper part of a first one of the electronic devices and below the air ventilation part of a second one of the electronic devices provided on the first electronic device. Air outside of the electronic equipment is taken into an inside of the second electronic device or air inside of the first electronic device is exhausted to the outside of the electronic equipment via the air intake and exhaust hole forming part, so that an amount of the air ventilated inside of the first electronic device is controlled.

A warp prevention structure for a printed circuit board, capable of serving also to perform the slack handling of cables. The warp prevention structure includes a first warp prevention fitting mounted on the printed circuit board in the vicinity of an upper edge thereof so as to extend along the upper edge, and a second warp prevention fitting mounted on the printed circuit board in the vicinity of a lower edge thereof so as to extend along the lower edge. Each of the first and second warp prevention fittings is integrally formed with a plurality of cable holders arranged at equal intervals.
