Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A high voltage electrical coupling comprising: a conductive connector with a plurality of separated spring contact fingers adapted to engage in a mating connector and extending from a common disk-shaped base connected to a cable; an annular insulating member around the connector between the fingers and the base and pressed flatwise against the base so as to form a seal between the base and fingers; and an insulative shroud of pressure-injection material molded around the insulating member, the base and the cable with the spring fingers substantially unconfined.
Claim 2
Dependent Claim
88 words
A high voltage electrical coupling comprising: a conductive connector with a plurality of separated spring contact fingers adapted to engage in a mating connector and extending from a common disk-shaped base connected to a cable; an annular insulating member around the connector between the fingers and the base and pressed flatwise against the base so as to form a seal between the base and fingers; and an insulative shroud of pressure-injection material molded around the insulating member, the base and the cable with the spring fingers substantially unconfined.
Claim 3
Dependent Claim
13 words
A coupling according to claim 1 wherein the shroud is of elastomeric material.
Claim 4
Dependent Claim
19 words
A coupling according to claim 1 wherein the shroud wholly contacts the connector with no substantial intervening air space.
Claim 5
Dependent Claim
14 words
A coupling according to claim 1 wherein the shroud is of injection molded material.
Claim 6
Dependent Claim
15 words
A coupling according to claim 1 wherein the annular insulating member is of elastomeric material.
Claim 7
Dependent Claim
22 words
A coupling according to claim 5 wherein the elastomeric material of the annular member is bonding-compatible with the material of the shroud.
Claim 8
Dependent Claim
27 words
A coupling according to claim 1 wherein the annular insulating member has a flange embedded in the shroud and opposing withdrawal of the connector from the shroud.
Claim 9
Dependent Claim
18 words
A coupling according to claim 7 wherein the shroud extends over the connector base to the spring fingers.
Claim 10
Dependent Claim
14 words
A coupling according to claim 1 including an insulated cable connected to the connector.
Claim 11
Dependent Claim
23 words
A coupling according to claim 9 wherein the insulation of the cable has a circumferential groove, and the shroud extends into the groove.
Claim 12
Independent Claim
104 words
The method of molding insulation on an assembly of a cable attached to a connector having spring fingers extending from a base comprising: fitting an annular member of resilient insulation around the connector between the fingers and the base, sealing the member in a socket of a mold with the fingers extending from one side of the member into the socket; and injecting insulative material into the mold onto the other side of the member thereby to seal the member in the socket and exclude insulative material from the fingers while expelling air from within the mold on the other side of the member.
