Abstract
Abstract A multiway connector assembly comprising a tubular metal outer casing (18), a plurality of electrical lead-through terminations (12) which extend through the outer casing, the terminations being coupled to respective pi-section filters (10), each of which is formed by two annular discoidal capacitors (14a, 14b) separated by a tubular inductive element (16). The outer electrodes of the capacitors of the pi-section filters are connected to metal earth planes (16) which are held in the outer casing (18) by a first releasable retention clip (24) such as to be in electrical connection with the casing. The inner electrodes of the capacitors are connected to associated ones of the terminations (12) by way of respective contact clips (32) which enable relative displacement of the capacitors and terminations for purposes of assembly and disassembly. A plurality of transient absorption devices (48) are mounted on a circuit board (50) through which the lead-through terminations (12) extend and which is held releasably in the outer casing (18) by way of a further retention clip (56) such as to connect the one sides of the transient absorption devices (48) to the casing. The circuit board (50) is coupled to the terminations (12) by further contact clips (32) which connect the terminations to the other sides of the associated transient absorption devices (48).

A multiway connector assembly comprising a tubular metal outer casing (18), a plurality of electrical lead-through terminations (12) which extend through the outer casing (18), the terminations (12) being coupled to respective pi-section filters (10), each of which is formed by two annular discoidal capacitors (14a, 14b) separated by a tubular inductive element (16), the outer electrodes of the capacitors of the pi-section filters being connected to metal earth planes (16a, 16b), characterised in that the metal earth planes (16a, 16b) are held in the outer casing (18) by first releasable retention means (22, 24) such as to be in electrical connection with the casing (18), and the inner electrodes of the capacitors (14a, 14b) being connected to associated ones of the terminations (12) by way of respective contact clips (32) which are adapted to enable relative displacement of the capacitors and terminations for purposes of assembly and disassembly, and in that a plurality of transient absorption devices (48) are mounted on a circuit board (50) through which the lead-through terminations (12) extend and which is held releasably in the outer casing (18) by way of said first or a further retention means such as to connect the one sides of the transient absorption devices (48) to the casing (18), the circuit board being coupled to the terminations (12) by further contact clips (32) which connect said terminations (12) to the other sides of the associated transient absorption devices (48).
Claim 2
Dependent Claim
240 words
A multiway connector assembly comprising a tubular metal outer casing (18), a plurality of electrical lead-through terminations (12) which extend through the outer casing (18), the terminations (12) being coupled to respective pi-section filters (10), each of which is formed by two annular discoidal capacitors (14a, 14b) separated by a tubular inductive element (16), the outer electrodes of the capacitors of the pi-section filters being connected to metal earth planes (16a, 16b), characterised in that the metal earth planes (16a, 16b) are held in the outer casing (18) by first releasable retention means (22, 24) such as to be in electrical connection with the casing (18), and the inner electrodes of the capacitors (14a, 14b) being connected to associated ones of the terminations (12) by way of respective contact clips (32) which are adapted to enable relative displacement of the capacitors and terminations for purposes of assembly and disassembly, and in that a plurality of transient absorption devices (48) are mounted on a circuit board (50) through which the lead-through terminations (12) extend and which is held releasably in the outer casing (18) by way of said first or a further retention means such as to connect the one sides of the transient absorption devices (48) to the casing (18), the circuit board being coupled to the terminations (12) by further contact clips (32) which connect said terminations (12) to the other sides of the associated transient absorption devices (48).
Claim 3
Dependent Claim
58 words
A multiway connector assembly as claimed in claim 1, wherein there is a first earth plane (16a) associated with and rigidly connected to first ones (14a) of the two capacitors of the pi-section filters and a second earth plane (16b) associated with and rigidly connected to the second ones (14b) of the two capacitors in the pi-section filters.
Claim 4
Dependent Claim
29 words
A multiway connector assembly as claimed in claim 2, wherein there is a second said releasable retention means ( 56) associated specifically with retention of said circuit board (50).
Claim 5
Dependent Claim
54 words
A multiway connector assembly as claimed in claim 3, wherein said second releasable retention means comprises a spring retention clip (56) adapted to be received in a circular internal groove (57) in the wall of the housing (18) and a resilient thrust washer (54) disposed between the clip (56) and the circuit board (50).
Claim 6
Dependent Claim
59 words
A multiway connector assembly as claimed in any of claims 2 to 4, wherein the first releasable retention means comprises a spring retention clip (24) adapted to be received in a circular internal groove (25) in the wall of the housing (18) and a resilient thrust washer (22) disposed between the clip (24) and the second earth plane (16b).
Claim 7
Dependent Claim
112 words
A multiway connector assembly as claimed in any of claims 1 to 5, wherein at least some of said clips (32) comprise a tubular member (36) whose one end is longitudinally slotted to form a plurality of contact fingers (38) which are bent slightly inwardly so that they will firmly grip the periphery of a lead-through termination (12) when pushed over same, the tubular member (36) also having an outwardly directed flange (40) which can be used to solder the clip to one of the discoidal capacitors (14), with a cylindrical portion at the other end of the clip received snugly within the inner periphery of that one of the discoidal capacitor.
Claim 8
Dependent Claim
88 words
A multiway connector assembly as claimed in any of claims 1 to 5, wherein at least some of said clips (32) comprise a metal tube whose one end is adapted to be received snugly within the inner periphery of one of the capacitors (14) and whose other end is deformed outwardly and inwardly to form a narrowed mouth (44) which resiliently grips a termination (12) passed therethrough, shoulder portions (46) being provided on the clips (42) to form areas where the clips can be soldered to the capacitors.
