Abstract
Abstract A grounding plate having a flanged edge wall continuously around its periphery is press fit into the open end of a connector part shell. The plate provides a continuous intimate contacting relationship between the plate flange and the inner wall of the connector shell. A plurality of openings are formed in the plate aligned with the connector contacts contained within the connector part. A length of shielding braid, which can be identical to that carried by a cable wire has one open end soldered onto a cable wire shield. A metal ferrule grounding plug has an open end which is soldered or otherwise electrically and mechanially secured to the other end of length of shield braid. The outer end of the grounding plug has a radially outwardly directed flange and a slotted side wall, such that the plug on being inserted into a grounding plate opening is compressed, and then when the flange has passed through the plate it snaps outwardly to lock the plug in place. An alternative form includes a removable grounding plate held within the connector part end by an end cap or connector shell extender.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
180 words
A cable shield termination system, comprising: an electrical connector part having a metal shell with an open end via which the cable with an electrical contact on its end it introduced; a metal disk received within the shell open end, said disk having edges which conductively engage an inner wall of the metal shell and an opening extending through the disk of sufficient dimensions to enable passage of the cable and electrical contact; a hollow metal grounding plug of external dimensions permitting fitting and contacting receipt within the disk opening and an internal opening sufficient to allow the cable to pass therethrough said grounding plug having a slotted side wall, first and second radially extending flanges larger than the disk opening cross-section, and the spacing between the first and second flanges being approximately equal to the disk thickness; and a predetermined length of a hollow tubular metal shield with one end conductively secured within the grounding plug opening, the other end of said tubular metal shield being for receipt on the cable and for conductive securement to the cable shield.
Claim 2
Dependent Claim
180 words
A cable shield termination system, comprising: an electrical connector part having a metal shell with an open end via which the cable with an electrical contact on its end it introduced; a metal disk received within the shell open end, said disk having edges which conductively engage an inner wall of the metal shell and an opening extending through the disk of sufficient dimensions to enable passage of the cable and electrical contact; a hollow metal grounding plug of external dimensions permitting fitting and contacting receipt within the disk opening and an internal opening sufficient to allow the cable to pass therethrough said grounding plug having a slotted side wall, first and second radially extending flanges larger than the disk opening cross-section, and the spacing between the first and second flanges being approximately equal to the disk thickness; and a predetermined length of a hollow tubular metal shield with one end conductively secured within the grounding plug opening, the other end of said tubular metal shield being for receipt on the cable and for conductive securement to the cable shield.
Claim 3
Dependent Claim
22 words
A cable shield termination system as in claim 1, in which the metal disk is press fit within the shell open end.
Claim 4
Dependent Claim
23 words
A cable shield termination system as in claim 2, in which the metal disk includes a continuous flange arranged about the disk periphery.
Claim 5
Dependent Claim
26 words
A cable shield terminations system as in claim 1, in which the cable shield and the hollow tubular metal shield are constructed of a metallic braid.
Claim 6
Dependent Claim
35 words
A cable shield termination system as in claim 1, in which the grounding plug further includes a unitary hollow sleeve which is received within the hollow tubular metal shield and electrically and mechanically secured thereto.
Claim 7
Dependent Claim
47 words
A cable shield termination system as in claim 1, in which the metal disk is releasably and slidably received within the metal shell open end, and means threadably received onto the metal shell open end to secure the metal disk in conductive contact with the metal shell.
Claim 8
Dependent Claim
35 words
A cable shield termination system as in claim 1, in which the spacing between the inwardly facing surface of the metal disk and the contact is so small as to preclude looping of the cable.
Claim 9
Dependent Claim
25 words
A cable shield termination system as in claim 1, in which the metal disk is mechanically and electrically secured to the metal shell by welding.
Claim 10
Dependent Claim
27 words
A cable shield termination system as in claim 1, in which the metal disk is mechanically and electrically secured to the metal shell by a conductive adhesive.
Claim 11
Independent Claim
155 words
A system for terminating a wire shield, comprising: a junction box having an open-ended electrically conductive shell through which the wire with a first electrical contact affixed to its end is introduced; conductive plate means covering the shell open end, said plate means having an opening located to be aligned with a second electrical contact located within the shell and complementary to the first contact; means for conductively and mechanically securing the plate means to the shell in a gap free manner; and a metal grounding plug for conductive securement to the wire shield and having an internal bore for receiving the wire therethrough, said grounding pug having external dimensions enabling receipt within the plate means opening, said grounding plug having a slotted side wall, first and second radially extending flanges larger than the conductive plate means opening, and the spacing between the first and second flanges being approximately equal to the plate means thickness.
Claim 12
Independent Claim
155 words
