Abstract
A high voltage CRT anode electrical coupling has a connector with several spring contact fingers extending from a base and an insulating ring around the connector between the base and fingers. An insulative shroud is molded around ring and base leaving the fingers unconfined.
Claims11
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.

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.
