Abstract
Abstract A screening arrangement for a multi-pin cable connector in which a known connector formed of synthetic material is screened by the use of a metal liner which is simply pressed into position within opposite halves of the known connector. The liner provides a low ohmic contact of the cable screen with the associated apparatus to which it is connected as well as suitable screening of the interior of the connector housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A multi-pin cable connector comprising: a housing formed of synthetic material and including a pair of mating halves and a metal pin connector base for being secured within the housing, said metal pin connector base having means for being coupled to a multi-wire cable having an associated cable screen, each of the internal walls of said mating halves having a metal liner and a metal bracket, said metal brackets of respective halves of said housing being arranged to clamp the cable screen therebetween wherein the housing halves are assembled, said metal brackets, liners, and pin base being associated together within the housing to form low-ohmic contacts between each of said brackets, liners and pin base.
Claim 2
Dependent Claim
115 words
A multi-pin cable connector comprising: a housing formed of synthetic material and including a pair of mating halves and a metal pin connector base for being secured within the housing, said metal pin connector base having means for being coupled to a multi-wire cable having an associated cable screen, each of the internal walls of said mating halves having a metal liner and a metal bracket, said metal brackets of respective halves of said housing being arranged to clamp the cable screen therebetween wherein the housing halves are assembled, said metal brackets, liners, and pin base being associated together within the housing to form low-ohmic contacts between each of said brackets, liners and pin base.
Claim 3
Dependent Claim
57 words
A multi-pin cable connector in accordance with claim 1 wherein each of said housing halves has a main recess for receiving the pin connector base and a further recess for receiving said cable screen, said metal liner extending across the surface of said main recess and said metal bracket being held into position in said further recess.
Claim 4
Dependent Claim
32 words
A multi-pin connector in accordance with claim 1 wherein said metal liner has projecting spikes which lodge into the respective halves of the synthetic material housing, thereby locking the liner into position.
Claim 5
Dependent Claim
33 words
A multi-pin connector in accordance with claim 1 wherein said liner is formed from a liner blank having tabs which are bent into position to make low-ohmic contacts with the pin connector base.
Claim 6
Dependent Claim
35 words
A multi-pin connector in accordance with claim 1 wherein the metal brackets are of spring material such that the assembling of the connector housing causes the cable screen to be lockingly held in position therein.
Claim 7
Dependent Claim
35 words
A multi-pin connector in accordance with claim 5 wherein the metal brackets are self-spring biasing within the respective housing halves to be self-retaining such that they do not become dislodged when the housing is dismantled.
Claim 8
Dependent Claim
41 words
A multi-pin connector in accordance with claim 6 wherein said metal brackets each comprise partially circular collar portions for clamping the cable screen therebetween and each bracket has a pair of supporting legs for making low-ohmic contact with said metal liner.
Claim 9
Dependent Claim
41 words
A multi-pin connector in accordance with claim 4 wherein each of said tabs is bent perpendicularly to the plane of the metal liner blank and wherein each tab of both of said liners make low-ohmic contact with said metal pin base.
