Description

(54) IMPROVEMENTS IN OR RELATING TO CONNECTOR ARRANGEMENTS.
(71) THE MARCONI COMPANY LIMITED, a British Company, of Marconi House, New Street, Chelinsford, Essex. CMl lPL.
do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to connector arrangements, and concerns for example edge launch connector arrangements for making connection to a triplate circuit.
A serious difficulty which is experienced with edge launch connectors for triplate circuits (as at present known) is that of tracking. Essentially, a triplate circuit consists of a sandwich of three conductive layers, of which the middle one is usually patterned, with insulating material between them. In one preferred form a triplate circuit consists of a sandwich of three layers of which the middle layer is a layer of insulating material having a conductive pattern on one or both sides, and the two outer layers are of insulating material with metallised outer coverings. The edge launch connector consists essentially of a conductive member carried by an insulating member within a housing; the conductive member has a spade at one end to fit between the middle layer of the triplate circuit and one or other of the outer layers (contacting part of the conductive pattern carried by the middle layer), whilst the other end of the conductive member is hollow to permit the central conductor of a co-axial cable to pass there through to engage the spade.
A limitation upon the voltage which maq be applied to the triplate circuit via the edge connector arises due to the tracking between the conductive member of the edge launch connector and the outer metallised coverings of the triplate circuit. The limitation can be serious where the voltage to be applied to the triplate circuit is relatively high (as, for example, where the triplate circuit is utilised to feed an antenna system).
One object of the present invention is to provide an improved edge launch connector arrangement for a triplate circuit in which titis limitation is reduced.
Accordingly, this invention provides an edge connector for making connection to a multilayer circuit, such as a triplate circuit feeding or embodying an aerial, so as to enable the circuit to be fed with a high voltage signal with a reduced risk of tracking, in which connector an insulating member carries a conductive member shaped at one end to engage the circuit, the insulating member being shaped at its outer end in such a manner as to extend (in use) over and beyond the edge of the circuit on both sides, the connector being for use with a circuit the metallised outer coverings on the outer layers of which are cut back to accommodate the projection of the insulating member over and beyond the edge of the circuit, the insulating member of the edge connector comprising a hollow stem carrying a channel section the walls of which project (in use) beyond the edge of the circuit, the arrange- ment being such that the hollow stem is a sliding fit in a conductive block which is clamped between two outer conductive plates each of which has a recess to accommodate the walls of the channel section so that in use the walls are clamped onto the underlying insulating material exposed by the cutting back, whilst the two outer conductive plates are clamped onto the metallised outer coverings adjacent the exposed underlying insulating material.
Preferably, the recesses in the two outlet conductive plates are tapered, and the wails of the channel section are so shaped and dimensioned as to fit therein.
The conductive member of the edge connector is preferably located within the hollow, conveniently tubular, stem of the insulating member, and is shaped to accept at its outer end the inner conductor of a co-axial cable, the tublar stem of the insulating member being recessed at its end remote from the channel section to accommodate the tubular insulator of the co-axial cable thereby to provide a relatively long tracking distance.
The invention extends, of course, to an edge connector as described and claimed herein in combination with a triplate circuit.
The invention is illustrated in and further described with reference to the drawing accompanying the Provisional Specification, which drawing is an exploded perspective view of an edge launch connector in accordance with the present invention. To the right of the edge connector, as viewed, is represented a portion of a triplate circuit to which the connector is to be connected.
kefening to the drawing, the edge connector consists of a copper block 1 through which passes a cylindrical hole 2. Attached by means d screws 3 to the block 1 are upper and lower plates 4 and 5 respectively.
These plates 4 and 5 are stepped (at 6) and each has a similar tapering recess (as 7 in tbe, case of lower plate 5).
A PTFE insulating member 8 is provided w a hollow cylindrical steal 9 dilnensioned to be a sliding fit within the hole 2 extending through the block 1. Upon the stem 9 is a channel section 10 the walls of which are shaped to kate in the recesses (such as 7) ia the upper and lower plates 4 and 5.
The stem 9 of the member 8 is ~vii',^S with a hole 11 which extends through the base of the channel section 10. Withht the hole 11 there is a metal co-axial connector 12 one end (13) of which is formed as a spit cinder. dimensioned to accept the probe of a co-axial connector and the other end (14) of which is shaped like a spade for connection into the triplate circuit 15 shown to the right, as viewed, of the drawing. The coaxial hole lis enlarged, as shown in dashed outhne at 16, towards the end of the cylindrBl portion 9 so as to provide reces sed accommodation for the end d a co-axial connector (not shown), thus providing a relatively long path for possible tracking in this region.
Turning to the triplate circuit 15, this consists of three layers 17, 18 and 19 of insulating material. The ,tw;o outer layers 17 and 19 have outer metall15ed coverings 20 and 21 respectivelyy and the middle layer 18 has a conductive pattem on one side (of wiiich pattern only part, referenced 22, is shown). In use, the spade end 14 of the metal connector 12 fits between layer 18 and 17 in contact with part 22 lof the conductive pattern on layer 18.
As so far descried, the triplate circuit 15 is wed known per se. However, the metal lised coverings 20 and 21 are cut back, as shown at 23 in the case of metallised cover ing 21, b accept the shape of the walls of the channel section 1Q, which walls fit within the recesses such as 7 in the upper and lower plates 4 and 5 of the edge connector. By this means, because the PTFE member 8 extends over the edge of the triplate circuit I5, with the metallised coverings 20 and 21 cut back accordingly, the tracking distance between the metal connector 12 and the metallised coverings 20 and 21 is considerably increased compared to a known edge launch connector in which the insulating member corresponding to insulating member 8 has a face which is flush with the edge of the triplate circuit 15.
When the edge connector is in position, with the spade end 14 of the metal connector 12 in contact with part 22 of the conductive pattern on layer 18, it is fixed to the triplate circuit by means of screws passing through holes 24 in 'the upper plate 4 and holes 25 extending through the sandwich of the triplate circuit 15 and screwed into screw holes 26 dn the lower plate 5.
The layer 18 may have conductive patterns on both sides, where for example couplers or dividers are formed as known per se.

An edge connector for making connection to a multi-layer circuit, such as a triplate circuit feeding or ernbodying an aerial, so as to enable the circuit to be fed with a high voltage signal with a reduced risk of tracking, in which connector an insulating member carries a conductive member shaped at one end to engage the circuit, the insulating member being shaped at its outer end in such a manner as to extend (in use) over and beyond the edge of the circuit on both sides, the connector being for use with a circuit the metaelsed outer coverings on the outer layers of which are cut back to accommodate the projection of the insulating member over and beyond the edge of the circuit, the insulating member of the edge connector comprising a hollow stem carrying a channel section the walls of which project (in use) beyond the edge of the circuit, the arrangement being such that the hollow stem is a sliding fit in a oonductive block which is clamped between two outer conductive plates each of which has a recess to accommodate the walls of the channel section, so that in use the walls are clamped onto the underlying. insulating material exposed Iby the cutting ck, whilst the two outer conductive plates are clamped onto the metallised outer coverings adjacent the. exposed underling insulating materiaL 2.
