Switchable Electrical Connector
US Patent:
4120552, Oct 17, 1978
Filed:
Jul 7, 1977
Appl. No.:
5/813521
Inventors:
Edward D. Winkler - Reading MA
Earl E. Dalrymple - Waltham MA
Earl E. Dalrymple - Waltham MA
Assignee:
Anderson Power Products, Inc. - Boston MA
International Classification:
H01R 1354, H01R 3330
US Classification:

Abstract:
A switchable electrical connector for use in explosion prone environments is disclosed. The connector utilizes two pairs of electrical connectors; the first pair provides a circuit switching function while the second pair permits the removable connection of a suitable load. Sealing means are used for the first pair of electrical connectors to isolate any switching arcs from the environment. A mechanically actuated interlock is employed to prevent electrical engagement of the first pair of connectors before engagement of the second pair of connectors and to prevent disengagement of the second pair of connectors before the disengagement of the first pair of connectors.
