Abstract

An electrical connector combination thoroughly sealed against moisture and dirt and resistant to temperature variations and shaking forces consists of a male connector (1) equipped with connector prongs (3) set in a casing (2) and a female connector (10) having corresponding sockets (12) disposed in a casing (13) in which a compressible seal plug (22) is set which surrounds the conductors which are electrically and mechanically affixed to the connector sockets (12). The seal plug 12 is compressed by an assembly of rigid parts including the casing plug (13), a metallic washer (25) and a cap nut (27), the last of which can be screwed tight with a certain torque to clamp the assembly. A sealing effect is exerted on the conductors (11) and the casing plug (13) in a radial direction without exposing the seal plug (22) to rotary movement. A seal ring (9) is seated on a forward section (15) of the socket casing plug (13) extending into the male connector casing (2). This seal ring seals the joint of the connector parts with the help of a connection sleeve acting through a bayonnet lock, without the seal ring being able to yield radially.
