ABSTRACT:
A connector, comprising an elongated body (1) of electrically insulating material, which has at its ends elements (6) for fastening the connector, and which carries several contact elements (2) of electrically conducting material. When assembled, one or more of the contact elements (2) being connected to an electrode (14) of one or more filter elements formed on a substrate (12), another electrode (15) of which is connected to a screen of electrically conducting material partially enclosing the contact elements (2). Said screen comprises a first frame-type cover (16) which is made up of two halves (18) and encloses the contact ends (3) of the contact elements (2), having lips (20) which project in the direction of the connection ends (4) of the contact elements (2), and to which said other electrode (15) of the filter elements is connected. Further, a second frame-type cover (17) partially enclosing the connection ends (4) of the contact elements (2) and to which also said other electrode (15) of the filter elements is connected. Said first (16) and second (17) frame-type covers engaging with each other in a manner such that the substrate (12) with the filter elements is confined between them and a connector optimum screened against interference signals is obtained.
