Abstract
Abstract A multi-polar shielded connector (15) includes a housing (24) having a plurality of accommodating portions (23) where end portions (17) of a plurality of shielded wires (16) together with terminals 18 are accommodated, respectively, a shielding member (25) provided in the housing (24), for covering the plurality of accommodating portions (23) in a lump to shield the end portions (17) of the shielded wires (16) and the terminals (18) connected to the end portions (17), a plurality of shield contact members (26) conductively contacting with respective braid wires (21) of the shielded wires 16, respectively, and a conductive block (27) assembled in the housing (24), for conductively connecting with the shielding member (25) and conductively connecting with the shielding member (25) to conductively connect the shielding member (25) and the shield contact members (26) to each other. Accordingly, in a multi-polar shielded connector, the number of component parts can be reduced, the structure can be simplified, a size reduction can be made possible, and manufacturing costs can be decreased.
