Abstract

Abstract A multi-way connector assembly comprising a tubular metal outer casing (16) and a plurality of electrical lead-through terminations (22) which extend through the outer casing (16), the terminations (22) carrying respective annular discoidal filter capacitors (10) whose outer electrodes are connected electrically to a metal ground plane (12) which is itself connected electrically to the outer tubular metal casing (16). The inner electrodes of the capacitors (10) are electrically coupled to the associated lead-through terminations (22) by respective contact clips (24) which are adapted to enable relative displacement of the capacitors (10) and terminations (22) for purposes of assembly and disassembly, the metal ground plane plate (12) being held in electrical connection with the outer casing (16) by means of a removable locking means (18).

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 141 words
A multi-way connector assembly comprising a tubular metal outer casing (16) and a plurality of electrical lead-through terminations (22) which extend through the outer casing (16), the terminations (22) being connected to respective filter capacitors (10) having first electrodes formed by or connected electrically to a ground plane in the form of a metal plate (12) which is itself connected electrically to the outer metal casing (16), characterised in that second electrodes of the capacitors (10) are electrically coupled to the associated lead-through terminations (22) by contact clips (24) which are adapted to enable relative displacement of the capacitors (10) and terminations (22) for purposes of assembly and disassembly and in that the metal plate (12) forming the ground plane is held in a position providing electrical connection with the outer casing (16) by means of a removable locking means (18;50).
Claim 2
Dependent Claim 141 words
A multi-way connector assembly comprising a tubular metal outer casing (16) and a plurality of electrical lead-through terminations (22) which extend through the outer casing (16), the terminations (22) being connected to respective filter capacitors (10) having first electrodes formed by or connected electrically to a ground plane in the form of a metal plate (12) which is itself connected electrically to the outer metal casing (16), characterised in that second electrodes of the capacitors (10) are electrically coupled to the associated lead-through terminations (22) by contact clips (24) which are adapted to enable relative displacement of the capacitors (10) and terminations (22) for purposes of assembly and disassembly and in that the metal plate (12) forming the ground plane is held in a position providing electrical connection with the outer casing (16) by means of a removable locking means (18;50).
Claim 3
Dependent Claim 52 words
A multiway connector assembly as claimed in claim 1, wherein the capacitors are in the form of discrete annular discoidal filter capacitors (10) having outer electrodes connected rigidly to the metal ground plane plate (12) and inner electrodes which are electrically coupled to the associated lead-through terminations by respective contact clips (24).
Claim 4
Dependent Claim 34 words
An assembly as claimed in claim 2, wherein the contact clips (24) comprise tubular elements (26) having a plurality of inwardly biassed spring fingers (28) for engaging the periphery of the lead-through terminations (22).
Claim 5
Dependent Claim 25 words
An assembly as claimed in claim 3, wherein the contact clips (24) are soldered permanently to the inner peripheries of the associated discoidal capacitors (10).
Claim 6
Dependent Claim 64 words
An assembly as claimed in claim 1, wherein the capacitors are formed as a planar array in a multilayer ceramic disc having metal layers (54,56,62) incorporated therein to form the capacitor electrodes, the multilayer structure having a plurality of axial holes (58) communicating with internal metal electrodes and receiving respective contact clips (66) which couple said internal metal electrodes to the associated lead-through terminations.
Claim 7
Dependent Claim 104 words
An assembly as claimed in claim 1, wherein the capacitors are formed in pairs with respective inductors to form a plurality of pi-section filter arrays, each such array comprising an inner tube of ferrite material and an outer tube of a ceramic material whose inner periphery carries two spaced areas of metallisation (74,76) forming first and second capacitor electrodes and whose outer periphery carries a further area of metallisation (78) forming a third capacitor electrode, the third electrode being connected rigidly to the earth plane (12) and the first and second electrodes being coupled to the associated termination (22) by respective contact clips (82a,82b).
Claim 8
Dependent Claim 35 words
An assembly as claimed in any of claims 1 to 6, wherein the locking means comprises a screw-threaded locking ring (18) which is received within a correspondingly screw-threaded portion (20) of the outer casing (16).
Claim 9
Dependent Claim 30 words
An assembly as claimed in claim 7, wherein there is disposed between the metal plate (12) forming the ground plane and the locking ring (18) an annular spacer ring (19).
Claim 10
Dependent Claim 52 words
An assembly as claimed in any of claims 1 to 6, wherein the locking means (18) comprises a corrugated cylindrical clip (50) of a metallic material which is spring loaded between the inner periphery of the outer casing (16) and the outer periphery of the metal plate (12) forming the ground plane.
Claim 11
Dependent Claim 42 words
An assembly as claimed in any of claims 1 to 9, wherein the one ends of the terminations are soldered to respective further terminations (38) mounted in a connector device (36) whose outer periphery is received snugly within the outer casing (16).
Claim 12
Dependent Claim 38 words
An assembly as claimed in any of claims 1 to 10, wherein the component surfaces disposed within the outer casing (16) are provided with a conformal coating (85) of a flexible protective material such as polyurethane or epoxy.
