Abstract
Abstract A means for terminating a cable wire shield (16) in an electrical connector (10) can provide effective protection against electromagnetic interference including radio frequency and electromagnetic pulse interference. <??>A metal plate (18) having at least one opening (20) is fixed in the open end of an electrical connector (10). In each opening (20) is fixed a hollow metal tube (21) through which the cable wires (15) pass. The metal shield (16) surrounding the cable wires (15) is electrically and mechanically fixed as a sleeve over the tube (21) and the plate (18) is secured to the connector shell (11) by means of a hollow metal adaptor (23) which passes over the cable and, when fixed to the connector, maintains the metal plate (18) in firm contact with the connector shell.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
Shield termination means (17) for connecting an electrical cable having a plurality of individual insulated conductors (15) surrounded by a shield (16) for protection against electromagnetic interference, including radio frequency and electromagnetic pulse radiation interference, to an electrical connector (10) having an outer metal shell (11) with an opening through which the cable wires (15) pass for connection therewithin, characterised by the following combination: a hollow metal adaptor (23) for securement to the connector shell (11) over the shell opening; a metal plate (18) for location within the shell opening, in contact with the shell, and having at least one opening (20) therethrough; a hollow metal tube (21) secured in said plate opening (20) through which tube the cable can pass and to which the cable shield (16) can be electrically and mechanically secured; said adapter (23) having parts (25) arranged to abut against the axially outwardly directed surface of the plate and a circumferential inner surface arranged for securement to the outer circumferential surface of the connector shell.

Claim 3
Dependent Claim
52 words
A method of connecting a shielded cable (as specified in claim 1) to an electrical connector (10) (as specified in claim 1) in which there is used shield termination means (17) according to claim 1, characterised in that the cable wire shield (16) is electrically and mechanically connected to the tube (21).
Claim 4
Dependent Claim
48 words
A method according to claim 2, characterised in that the cable wire shield (16) is electrically and mechanically connected to the tube (21) by a fusible metal ring (26) clamping the shield (16) around the surface of the tube (21) behind an enlargement (22) of the tube (21).
Claim 5
Dependent Claim
56 words
A method according to claim 2, characterised in that the cable wire shield (16) is electrically and mechanically connected around the tube (21) by metal ring means (27) received over the shield (16) and the underlying tube (21), said ring means (27) being clamped thereon by the heat-induced shrinking member (28) received over said ring means.
Claim 6
Dependent Claim
45 words
A method according to claim 2 characterised in that the cable wire shield (16) is electrically and mechanically connected around the tube (21) by a ferrule (29) located over the shield (16) and behind an enlargement (22) of the tube (21) and being clamped thereon.
Claim 7
Independent Claim
39 words
A method according to any of claims 2 to 5 characterised in that the shell outer surface adjacent the opening is knurled and the adapter (23) is clamped onto the knurled surface by the application of a magnetic field.
Claim 8
Independent Claim
56 words
A method according to any of claims 2 to 5 characterised in that the shell outer surface adajcent the opening therein is cylindrical and includes a first depression (31) extending circumferentially thereabout, said adapter (23) being received onto the cylindrical shell (11) and clamped thereto with parts of the adapter extending into the first depression (31).
Claim 9
Dependent Claim
35 words
A method according to claim 7, characterised in that a second circumferential depression (30) in the shell (11) includes an 0-ring (32) which is deformed into sealing relation by the adapter (23) being clamped thereover.
Claim 10
Dependent Claim
17 words
A method according to claim 8 wherein the second depression (30) is within the first depression (31).
Claim 11
Independent Claim
51 words
A method according to any of claims 2 to 8 characterised in that the walls defining the shell opening include a recessed shoulder (19), said metal plate (18) being in abuttment against said shoulder and said shell (11) being deformed inwardly continuously opposite the plate edges for securing the plate therewithin.
