HIGH-TEMPERATURE, HIGH-PRESSURE VACUUM RELAY

摘要

A relay assembly includes a switch body, an adaptor sleeve, a feed-through base, and an encapsulating resin. The switch body includes a flange extending orthogonally from a portion of a housing and leads. The adaptor sleeve is substantially cylindrical with apertures in the sleeve wall. A first end of the adaptor sleeve encircles at least a portion of the switch body and is attached to the flange. The feed-through base is attached to a second end of the adaptor sleeve to enclose the second end and includes holes through which conductors extend; contacts, inside the adaptor sleeve, joining each conductor to one of the leads; and insulators through which each conductor extends. The flange, adaptor sleeve, and feed-through base form an envelope around the portion of the housing, the contacts, and the leads. The resin fills the envelope and encapsulates the portion of the housing, the contacts, and the leads.

1. A relay assembly, comprising:
a switch body including a substantially cylindrical housing to house a coil and other internal switching components, wherein the switch body includes:
a flange extending orthogonally from a portion of the housing, andmultiple leads extending from an end of the cylindrical housing; a substantially cylindrical adaptor sleeve with one or more openings in a wall of the sleeve, wherein a first end of the adaptor sleeve encircles at least a portion of the switch body and is attached to the flange; a feed-through base, attached to a second end of the adaptor sleeve to enclose the second end of the adaptor sleeve, wherein the feed-through base includes:
multiple holes through which conductors extend from inside the adaptor sleeve to outside the adaptor sleeve,multiple contacts, inside the adaptor sleeve, joining each conductor to one of the multiple leads, andmultiple insulators, adjacent to each of the multiple holes, through which each conductor extends,wherein the flange, the adaptor sleeve, and the feed-through base form an envelope around the portion of the housing, the multiple contacts, and the multiple leads; and a resin encapsulating the portion of the housing, the multiple contacts, and the multiple leads within the envelope.
