Abstract
Abstract A shielded electrical connector for surface connection to a printed circuit board comprises an electrically insulative body supporting a plurality of electrical contacts. Each contact includes a first portion for making contact with a complementary contact of a mateable connector when in use, and a second portion adapted to be connected to a surface of a printed circuit board. The connector further includes electrically conductive shielding contact means mounted on the body for shielding or grounding the electrical contacts. The shielding contact means comprises a plurality of electrically connected shielding finger contacts that are adapted to be connected to the printed circuit board surface. As such, when the connector is mounted to the circuit board, the electrical contacts and the finger contacts may be simultaneously connected to conductive pads on the printed circuit board by conventional reflow soldering techniques.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
A shielded connector for surface connection to a printed circuit board, which connector comprises a body of electrically insulating material, a multiplicity of electrical contacts, each contact having a first portion for making contact with a contact of a mateable connector, in use, and a second portion adapted to be connected to a surface of a printed circuit board, electrically conductive shielding contact means mounted on said body for shielding or grounding said electrical contacts, which shielding contact means comprise a plurality of electrically connected shielding finger contacts adapted to be connected to said printed circuit board surface, and hinge means for hingedly engaging the shielding contact means with the body at a location remote from the finger contacts, said hinge means including a rolled edge portion of the shielding contact means and lip means on said body.
Claim 2
Dependent Claim
138 words
A shielded connector for surface connection to a printed circuit board, which connector comprises a body of electrically insulating material, a multiplicity of electrical contacts, each contact having a first portion for making contact with a contact of a mateable connector, in use, and a second portion adapted to be connected to a surface of a printed circuit board, electrically conductive shielding contact means mounted on said body for shielding or grounding said electrical contacts, which shielding contact means comprise a plurality of electrically connected shielding finger contacts adapted to be connected to said printed circuit board surface, and hinge means for hingedly engaging the shielding contact means with the body at a location remote from the finger contacts, said hinge means including a rolled edge portion of the shielding contact means and lip means on said body.
Claim 3
Dependent Claim
58 words
A connector as claimed in claim 1 wherein each finger contact of the shielding contact means passes between an associated pair of electrical contacts such that connections between said finger contacts and a printed circuit board, in use, lie nearer an edge of the printed circuit board than connections between the electrical contacts and the printed circuit board.
Claim 4
Dependent Claim
46 words
A connector as claimed in claim 2 comprising holding means intermediate the hinge means and free ends of the finger contacts for engaging the body at one or more locations spaced apart form the hinge means to hold together the shielding contact means and the body.
Claim 5
Dependent Claim
46 words
A connector as claimed in claim 3 wherein the holding means comprise tang means engageable with an abutment surface of the body such that, with the hinge means engaged, the holding means operates with a snap-fit once the tang means have moved past the abutment surface.
Claim 6
Dependent Claim
36 words
A connector as claimed in claim 1 wherein the electrical contacts are arranged in at least one row and the finger contacts are arranged in a row parallel to the or each row of electrical contacts.
Claim 7
Dependent Claim
42 words
A connector as claimed in claim 1 comprising two sets of electrical contacts and shielding contact means, one set for contacting one side of a printed circuit board, and the other set for contacting the other side of a printed circuit board.
Claim 8
Dependent Claim
22 words
A connector and printed circuit board assembly comprising a printed circuit board and a surface mounted connector as claimed in claim 1.
Claim 9
Dependent Claim
119 words
A method of surface mounting a shielded connector as claimed in claim 1 on a printed circuit board, comprising the steps of: (a) assembling the connector, (b) providing on the printed circuit board solder pads at locations corresponding to the desired locations of the electrical contacts and the finger contacts on the board, (c) engaging the connector with the printed circuit board such that the electrical contacts and the finger contacts lie against respective solder pads, (d) heating the assembled connector and printed circuit board sufficiently to melt the solder, and (e) cooling the assembly to fuse the solder, whereby the electrical contacts and the finger contacts are simultaneously connected to the solder pads on the printed circuit board.
Claim 10
Dependent Claim
17 words
A method as claimed in claim 8 wherein the heating step is carried out in an oven.
