Abstract

PROBLEM TO BE SOLVED: To enhance the reliability of a connector device in which socket connectors of edge type are fitted with a dustproof cover so as to preclude intrusion of foreign matter such as dust into the connector case. SOLUTION: Those of socket connectors 5 which are out of service for a long period of time are fitted with a dustproof cover 21 to cover a board insert hole 7 provided in a connector case 6. The cover 21 precludes intrusion of foreign matter such as dust into the hole 7. This also prevents foreign matter from staying as pinched by connection pins to cause poor performance of electric insulation and precludes occurrence of imperfect contacting of connection pins with the edge connector terminal to lead to enhancement of the reliability of the connector device.
