Abstract

Abstract A minature connector capable of providing an electrically shielded connection at close pin spacings comprises a double sided printed circuit board (PCB) having parallel tracks etched on an upper surface and contacts soldered thereto. A screening shell having insulation material on an inner surface encloses the PCB end contacts and is electrically connected to the edges of the undersurface of the PCB to complete a rectangular-section screening casing. A stack of such assemblies is enclosed in a grouper housing to form, for example, a six by four connector array which is electrically shielded.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 192 words
A shielded connector for connecting a cable or cables to a backplane having at least one row of parallel connection pins, the connector comprising a support plate of insulating material carrying a number of spaced parallel pin socket contacts on one face thereof and an electrically conductive layer forming a grounded plane on the other face thereof, the pin socket contacts being adapted for electrical connection to respective wires of said cable or cables, and a screening shell joined to the support plate to form a casing of rectangular cross section enclosing the pin socket contacts, the screening shell comprising an electrically conductive outer layer which is electrically connected to the ground plane layer of the support plate and an inner layer of an insulating material, said screening shell embracing transversely opposed edges of the support plate such that corresponding edge portions of the screening shell underlie the opposed support plate edge portions and such that insulating material is absent from the screening shell edge portions in a manner such that electrical contact is made between the screening shell and the electrically conductive layer on said other face of the support plate.
Claim 2
Dependent Claim 192 words
A shielded connector for connecting a cable or cables to a backplane having at least one row of parallel connection pins, the connector comprising a support plate of insulating material carrying a number of spaced parallel pin socket contacts on one face thereof and an electrically conductive layer forming a grounded plane on the other face thereof, the pin socket contacts being adapted for electrical connection to respective wires of said cable or cables, and a screening shell joined to the support plate to form a casing of rectangular cross section enclosing the pin socket contacts, the screening shell comprising an electrically conductive outer layer which is electrically connected to the ground plane layer of the support plate and an inner layer of an insulating material, said screening shell embracing transversely opposed edges of the support plate such that corresponding edge portions of the screening shell underlie the opposed support plate edge portions and such that insulating material is absent from the screening shell edge portions in a manner such that electrical contact is made between the screening shell and the electrically conductive layer on said other face of the support plate.
Claim 3
Dependent Claim 39 words
A connector according to claim 1 wherein the support plate is formed of double-sided printed circuit board, which has been etched on said one face to provide tracks on which the respective contacts are mounted in electrical contact therewith.
Claim 4
Dependent Claim 30 words
A connector according to claim 1 wherein the screening shell is formed of conductive metal and the inner layer of insulating material comprises expanded polytetrafluorethylene impregnated with a thermosetting resin.
Claim 5
Dependent Claim 40 words
A connector according to claim 1 wherein the spaced parallel pin socket contacts have two outermost pin socket contacts that are electrically interconnected and adapted to be attached to ground wires of a pair of cables attached to the connector.
Claim 6
Dependent Claim 17 words
A connector according to claim 1 wherein the pin contacts are spaced apart at 2 mm centres.
Claim 7
Dependent Claim 37 words
A connector according to claim 1 wherein the screening shell has a rearwardly extending portion in a rearward reduced width region of the support plate adapted for attachment of the cable or cables to the support plate.
Claim 8
Dependent Claim 18 words
A connector according to claim 1 which is compatible with the METRAL (trademark) 2 mm spacing connector protocol.
Claim 9
Dependent Claim 162 words
A shielded connector for connecting a cable or cables to a backplane having at least one row of parallel connection pins, which connector comprises a group of assemblies arranged in a stack and held within a grouper housing, each assembly comprising a support plate of insulating material carrying a number of spaced parallel pin socket contacts on one face thereof and an electrically conductive layer forming a ground plane on the other face thereof, the pin socket contacts being adapted for electrical connection to respective wires of said cable or cables and a screening shell joined to the support plate to form a casing of rectangular cross-section enclosing the pin socket contacts, the screening shell comprising an electrically conductive outer layer which is electrically connected to the ground plane layer of the support plate and an inner layer of an insulating material; said grouper housing holding together the stack of assemblies such that the pin socket contacts are held in an array.
Claim 10
Dependent Claim 162 words
A shielded connector for connecting a cable or cables to a backplane having at least one row of parallel connection pins, which connector comprises a group of assemblies arranged in a stack and held within a grouper housing, each assembly comprising a support plate of insulating material carrying a number of spaced parallel pin socket contacts on one face thereof and an electrically conductive layer forming a ground plane on the other face thereof, the pin socket contacts being adapted for electrical connection to respective wires of said cable or cables and a screening shell joined to the support plate to form a casing of rectangular cross-section enclosing the pin socket contacts, the screening shell comprising an electrically conductive outer layer which is electrically connected to the ground plane layer of the support plate and an inner layer of an insulating material; said grouper housing holding together the stack of assemblies such that the pin socket contacts are held in an array.
Claim 11
Dependent Claim 33 words
A connector according to claim 8 wherein the grouper housing is formed of a resilient material and is adapted to be fitted around the stock of assemblies after attachment of respective cables thereto.
Claim 12
Dependent Claim 88 words
A connector according to claim 8 wherein the screening shell and support plate of each assembly protrudes forwardly of the parallel pin socket contacts, and wherein the grouper housing comprises a front end portion to allow electrical contact with the respective pin socket contacts through said end portion, the end portion comprising a plurality of ridges along its inner face, each ridge locating within said forwardly protruding portion of a respective screening shell support plate assembly such as to hold the assemblies in position within the grouper housing.
Claim 13
Dependent Claim 35 words
A connector according to claim 8 wherein the grouper housing is open at either lateral side thereof to enable a plurality of such connectors to be connected side-by-side to the backplane at minimal mutual spacing.
Claim 14
Dependent Claim 18 words
A connector according to claim 8 which is compatible with the METRAL (trademark) 2 mm spacing connector protocol.
