PURPOSE:To obtain a shelf which restrains the radiation of sprious radio waves from a circuit package of a printed board, facilitate wiring connection without decreasing the packaging ratio, and simplifies maintenance, by constituting a shelf main body, a back board, and a front cover which are individually specified. CONSTITUTION:A circuit package 1 is provided with an outer connection terminal 2 in the front side, and a connector 3 in the rear side, which connector 3 is used for backward plug-in connection. A shelf main body 5 is equiped with a guide means 51 which accommodates the packages 1 in a parallel arrangement. Connectors 31, with which the connectors 3 of the circuit packages 1 are insertion-connected, are arranged on a back board 6 which is constituted of a printed wiring board for mutual connection. A connection wiring means 71 covers the front side of the shelf main body 5, elctromagnetically shields the shelf inside, comes into contact-connection with outer connection terminals 2 of the circuit packages 1 mounted in the inside, and constitutes mutual wiring connection. Connection connectors 8 which are connected with the connection wiring means 71 and connect it with outer wirings 88 are arranged on a front side cover 7, so as to face the front side. |
