PURPOSE:To prevent the discharge of noises to the outside of a box body while obviating intrusion to a printed board of external noises by fast sticking a shelf front frame plate member to the internal side face of a box-body side plate under the state in which an inserting section, to which the other party side connector is connected, is formed to the box-body side plate and inserted into a window for the connector and fixing a card edge type connector. CONSTITUTION:Both the surface and the rear except a contact edge 11 of a printed board 10 having slits 15 in the contact edge 11 section are covered with a pan-shaped shield plate 10A. Consequently, the periphery of the contact 22 of a card edge type connector 20 brought into contact elastically with a contact pattern 12 is covered with a metallic shelf 23 and the contact 22 is shielded. The metallic shelf 23 is grounded to a box-body side plate 2 through a shelf front frame plate member 26. Consequently, noises are discharged into a box body from not only contact 22 itself but also the contact pattern 12 section, and the noises are hardly discharged to the outside of the box body. Even when noises intrude into the box body from the clearance of a cover and the box body, the noises hardly penetrate into the printed board. |
