Abstract

A connector assembly having enhanced shielding against electromagnetic interference. A second ground connection between the plug and the socket is provided which is in the form of a contact ring. The additional contact ring has grounding fingers and is spaced behind the first contact ring to provide a multiple barrier against interference. The slots of one contact ring are offset from the slots of the other ring.

Claims

1. A connector assembly comprising a plug and a socket for lines shielded against electromagnetic waves and having at least one conductor, with a first, at least partially elastic ground contact ring disposed in an annular groove in the housing of either the plug or the socket and establishing a ground connection between the plug and the socket, characterized in that at least one additional ground contact ring is provided which establishes a second ground connection between the plug and the socket, said additional ground contact ring being at least partially elastic and being disposed in said annular groove and at an axial distance from said first ground contact ring, each ground contact ring being formed of a spring steel strip and having a first edge portion immovably fastened to said annular groove and a second edge portion in the form of a spring comb having spring fingers oriented radially, said spring fingers being defined by radial slots extending from said second edge portion to said first edge portion and said spring fingers having free ends, the free ends of said spring fingers of each contact ring facing the free ends of the other contact ring but being spaced therefrom and being offset in the circumferential direction such that said slots of one of said contact rings confront the free ends of said spring fingers of said other contact ring, whereby the shielding effectiveness is improved.

2. The connector assembly of claims 1, characterized in that said first edge portions of said contact rings are disposed at opposite endwalls of said annular groove and said spring combs have a concave form.
