Abstract

An electrical mating connector has a basic body of an insulating material with a collar surrounding the plug-in region of the contact elements, the basic body being provided with a conductive coating for the purpose of shielding and that an interposed, elastic, conductive seal is provided for connecting the coating to a printed circuit board.

Claims

1. An electrical connector for a circuit board operable to be connected with a mating connector, the electrical connector comprising a connector body made of an insulating material, said connector body forming a recess having a bottom part and a recess wall means extending from said bottom part, said bottom part having passages, contact elements passing through circuit passages and extending into said recess, said bottom part being disposed on said circuit board, conductive sealing means between said connector body and said circuit board providing an electrically conductive seal means between said connector body and said circuit board, contact means on said recess wall means disposed to face said recess, and a conductive coating on said recess wall means and on said contact means, said contact means making electrical contact with an interconnected mating connector disposed in said recess.

2. An electrical connector according to claim 1 wherein said conductive sealing means comprises receiving means in said bottom part of said connector body, said conductive sealing means further comprising an elastic and conductive sealing material disposed in said receiving means.

3. An electrical connector according to claim 2 wherein said receiving means comprises a recess in said bottom part of said connector body, said elastic and conductive sealing material being disposed in said recess.

4. An electrical connector according to claim 1 wherein said contact meads comprises thickened projections projecting from said recess wall means and facing said recess, said thickened projections contacting said interconnected mating connector disposed in said recess.

5. An electrical connector according to claim 1 wherein said recess wall means has integrally formed flexible tongues which biasingly contact said interconnected mating connector disposed in said recess.

6. An electrical connector according to claim 5 wherein each of said tongues is a three-sided tongue formed by three cut-outs in said recess wall means.

7. An electrical connector according to claim 5 wherein said tongues have tongue end portions and a thickened section on said tongue end portion facing said recess, said thickened section engaging said interconnected mating connector disposed in said recess.

8. An electrical connector according to claim 1 wherein said recess wall means comprises a recess wall structure and a frame means disposed on said recess wall structure, said conductive coating extending over said frame means, said frame means having an inside section facing said recess, said inside section of said frame means making electrical contact with said interconnected mating connector disposed in said recess.

9. An electrical connector according to claim 8 wherein said conductive coating extends between said frame means and said conductive seal means and between said circuit board and said conductive seal means.

10. An electrical connector according to claim 8 wherein said inside section of said frame means has flexible tongues integrally formed with said inside section, said tongues being operable to biasingly contact said interconnected mating connector disposed in said recess.

11. An electrical connector according to claim 10 wherein said conductive coating extends over said frame means including said tongues.

12. An electrical connector according to claim 8 further comprising an elastic and electrically conductive sealing material between said frame means and said circuit board.

13. An electrical connector according to claim 8 wherein said recess wall structure has a terminating end along with an inside face and an outside face, said frame means having a generally U-shaped cross-sectional configuration having spaced leg walls and an end wall, said recess wall structure being disposed in said U-shaped configuration such that said terminating end of said recess wall structure is juxtaposed to said end wall of said recess and said inside and outside faces of said recess wall structure are juxtaposed to the respective spaced leg walls.

14. An electrical connector according to claim 1 wherein said recess wall means comprises a recess wall structure and a plurality of flexible tongues juxtaposed to said recess wall structure, said flexible tongues and said recess wall structure being connected to said bottom part.

15. An electrical connector according to claim 14 wherein said recess wall structure, said tongues and said bottom part are integrally formed as a one-piece unit.

16. An electrical connector according to claim 14 wherein said recess wall means further comprises integrally formed ribs extending from said recess wall structure toward said recess, said ribs being disposed on either side of said flexible tongues.

17. An electrical connector according to claim 14 wherein said flexible tongues are spaced from said recess wall structure.

18. An electrical connector according to claim 16 wherein said ribs have an inner rib wall facing said recess, said flexible tongues having thickened projections which extend beyond said inner rib wall of said ribs into said recess.

19. An electrical connector according to claim 18 wherein said conductive coating extends over said recess wall structure, said flexible tongues, said ribs and said thickened projections.

20. An electrical connector for a circuit board operable to be connected with a mating connector, the electrical connector comprising a connector body made of an insulating material, said connector body forming a recess having a bottom part and a recess wall means extending from said bottom part, said bottom part having passages, contact elements passing through said passages and extending into said recess, said bottom part being disposed on said circuit board, said recess wall means comprising a recess wall structure and a frame means disposed on said recess wall structure, electrically conductive seal material between said frame means and said circuit board providing an elastic and electrically conductive seal between said frame means and said circuit board, contact means on said frame means disposed to face said recess, and a conductive coating on said frame means and on said contact means, said contact means making electrical contact with an interconnected mating connector disposed in said recess.
