Abstract
Abstract An electrical shielding arrangement is provided for interconnected printed circuit boards through an electrical connector (e.g. edge connector). One of the boards has the edge connector secured to it and includes a metal ground plane and a plated through hole which extends through the board and which makes effective contact with the metal ground plane. The plated through hole receives as a press fit therein a metal fixing pin or stud of compliant metal which extends from the base of the connector body and the top end of which is positioned for making electrical contact with a metal ground plane included in a printed circuit board the edge of which is received by a cavity provided in the connector body. The connector has spring contacts which make electrical contact with contact pads or the like at or near the edge of the inserted board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
An electrical shielding arrangement for printed circuit or wiring boards electrically interconnected by means of an electrical connector, characterised in that one of the boards to which the connector is secured includes a conductive ground plane and at least one plated through hole which extends through the board and makes effective electrical connection with the ground plane of the board at least for electrical shielding purposes and which receives as a press or force fit therein a conductive fixing pin or stud, preferably of compliant metal, one end of which extends from the body of the connector and the other end of which is positioned for making effective electrical connection, preferably directly, with a metal ground plane included in a further printed circuit or wiring board.
Claim 2
Dependent Claim
126 words
An electrical shielding arrangement for printed circuit or wiring boards electrically interconnected by means of an electrical connector, characterised in that one of the boards to which the connector is secured includes a conductive ground plane and at least one plated through hole which extends through the board and makes effective electrical connection with the ground plane of the board at least for electrical shielding purposes and which receives as a press or force fit therein a conductive fixing pin or stud, preferably of compliant metal, one end of which extends from the body of the connector and the other end of which is positioned for making effective electrical connection, preferably directly, with a metal ground plane included in a further printed circuit or wiring board.
Claim 3
Dependent Claim
164 words
An electrical shielding arrangement between printed circuit boards electrically connected by means of an edge connector, characterised in that one of the boards to which the edge connector is secured includes a conductive ground plane and at least one plated through hole which extends through the board and makes an effective electrical connection, at least for electrical shielding purposes, with the ground plane of the board and which receives as a press or force fit therein a conductive fixing pin or stud, preferably of compliant metal, one end of which extends from the insulating body at the edge connector and the other end of which is positioned for making effective electrical connection, at least for electrical shielding purposes, with a conductive ground plane included in a printed circuit board having an edge thereof received by an edge-receiving cavity of the connector body so that spring contacts of the edge connector make electrical contact.with contact means positioned at or near the edge of the board.
Claim 4
Dependent Claim
164 words
An electrical shielding arrangement between printed circuit boards electrically connected by means of an edge connector, characterised in that one of the boards to which the edge connector is secured includes a conductive ground plane and at least one plated through hole which extends through the board and makes an effective electrical connection, at least for electrical shielding purposes, with the ground plane of the board and which receives as a press or force fit therein a conductive fixing pin or stud, preferably of compliant metal, one end of which extends from the insulating body at the edge connector and the other end of which is positioned for making effective electrical connection, at least for electrical shielding purposes, with a conductive ground plane included in a printed circuit board having an edge thereof received by an edge-receiving cavity of the connector body so that spring contacts of the edge connector make electrical contact.with contact means positioned at or near the edge of the board.
Claim 5
Dependent Claim
67 words
An electrical shielding arrangement as claimed in claim 2, characterised in that the end of the fixing pin or stud remote from the printed circuit board to which the connector is secured engages with a plated edge of the board inserted into the edge-receiving cavity of the connector, the plated edge being electrically connected, at least for shielding purposes, with the ground plane of the inserted board.
Claim 6
Dependent Claim
127 words
An electrical shielding arrangement as claimed in claim 2 or 3, characterised in that the spring contacts of the connector have curved parts which engage with dome-shaped contact pads or pads otherwise having a convex profile attached to the board near its edge so that as the board edge is inserted into the connector cavity the curved parts of the spring contacts ride up over the contact pads beyond the centre lines thereof and thereby provide forces at the positions of contact engagement which act to enhance retention of the board in the connector cavity and establish pressure engagement between an end of the fixing pin or stud and the conductive ground plane of the board, either directly or through a plated edge of the inserted board.
Claim 7
Dependent Claim
65 words
An electrical shielding arrangement as claimed in claim 4, characterised in that the angle of inclination of the connector spring contacts relative to the direction of insertion and withdrawal of the board on the respective sides of the curved parts of the contacts provides for ease of insertion of the board into the connector and high retentivity of the board within the connector once inserted.
Claim 8
Dependent Claim
28 words
An electrical shielding arrangement as claimed in any preceding claim, characterised in that a substantial part of the connector body is embraced by a metal shroud or cover.
