Abstract
A shielded connector assembly for interconnecting individual conductors in an electrical wire harness is provided with a ground ring which eliminates unshielded conductor wire segments after the individual conductor shielding has been stripped. A filter ring assembly is included in the connector assembly for filtering high frequency signals to eliminate cross talk between high and low frequency signal conductors in the same wire harness. Transmission leakage is also eliminated at the juncture between the individual conductors and a circuit board included in the assembly.
Claims12
An interface system for interconnecting individual signal conductor wires to at least one multiconductor path circuit board in a grounded environment, said system comprising:
- a) an ambient EMI-shielding housing which is grounded to said grounded environment, and in which said circuit board is disposed;
- b) an ambient EMI-shielding wire harness containing said individual signal conductor wires, each of said signal conductor wires having its own individual shielding sheath;
- and
- c) a grounding ring secured to said housing and electrically grounded by said housing said grounding ring having a first surface abutting said circuit board, said grounding ring including a plurality of passages through which individual stripped bare conductor wires extend prior to their being connected to said circuit board, and said grounding ring including a second surface distal of said first surface, which second surface projects toward said wire harness and extends beneath said individual shielding sheaths so that said second surface serves to electrically ground said bare conductor wires internally of their individual shielding sheaths.
An interface system for interconnecting individual signal conductor wires to at least one multiconductor path circuit board in a grounded environment, said system comprising:
- a) an ambient EMI-shielding housing which is grounded to said grounded environment, and in which said circuit board is disposed;
- b) a wire harness containing said individual signal conductor wires, each of said signal conductor wires having an individual shielding sheath, said individual shielding sheaths being stripped away from said conductor wires to create bare wire end portions which are electrically connected to selected conductor paths in said circuit board;
- and
- c) a grounding cap disposed adjacent to said circuit board, said grounding cap being electrically grounded to said housing, and said grounding cap having a plurality of blind passages which blind passages are positioned so as to receive individual increments of bare conductor wire which may project beyond said circuit board, whereby said grounding cap is operable to eliminate post circuit board interconductor wire interference caused by signal emissions from said projecting bare conductor wire increments.
An interface system for interconnecting individual signal conductor wires to at least one multi-conductor path circuit board in a grounded environment, said system comprising:
- a) an ambient EMI-shielding housing which is grounded to said grounded environment, and in which said circuit board is disposed;
- b) a wire harness containing said individual signal conductor wires, each of said signal conductor wires having an individual shielding sheath;
- and
- c) a filter ring in said assembly between said wire harness and said circuit board, said filter ring including restricted passages through which high frequency signal transmitting conductor wires extend, said restricted passages containing filters which are operable to prevent high frequency to low frequency inter-conductor wire cross talk within the interface system.
An interface system for interconnecting individual signal conductor wires to at least one multi-conductor path circuit board in a grounded environment, said system comprising:
- a) an ambient EMI-shielding housing which is grounded to said grounded environment, and in which said circuit board is disposed;
- b) a wire harness containing said individual signal conductor wires, each of said signal conductor wires having its own individual shielding sheath;
- c) a split ring housing interposed between said wire harness and said shielding housing, said split ring housing having mating halves which combine to form said split ring housing, said individual signal conductor wires passing through said split ring housing to said shielding housing;
- d) a cover plate interposed between said wire harness and said split ring housing, said cover plate including a passage through which said signal conductor wires pass from said wire harness into said split ring housing;
- and
- e) means for securing said cover plate to said mating halves of said split ring housing to join said halves together to form said split ring housing.
