ABSTRACT:
A separable waterproof electrical connector for a plurality of pairs of axially interconnectable cylindrical electrical terminals coupled to the ends of insulated wires, each terminal having an annular external recess in its cylindrical peripheral surface.
The connector comprises a pair of elongated, rigid, non-conductive elastomeric, tubular members having generally complementary end portions fitted one into the other. A soft elastomeric sealing sleeve is concentrically interposed between the interengaged end portions to prevent the passage of moisture therebetween. Releasable clamping means on the exterior of the tubular member end portion hold the latter in engagement.
Each elastomeric tubular member has an interior partition wall extending laterally of its longitudinal axis in juxtaposition to the interengaged end portions. Each partition wall has a plurality of axially extending apertures therethrough that are equally spaced around the longitudinal axis of the tubular members. The electrical terminals are seated in the apertures.
A portion of the wall of each aperture comprises an axially extending cantilevered locking member hinged at one end to the partition wall and having a detent spaced from its hinged end. The detent is adapted to engage the external recess on the terminal seated in a respective aperture to prevent axial displacement of the latter. Each partition wall has an axially extending cavity communicating with the locking members. A displaceable plug means is seated in the partition cavity in abutting relation to the locking member to hold the detents on the latter in the respective terminal recesses.
A grommet is seated in the tubular member outwardly of the partition wall through which the insulated wires extend. The grommets are in sealing engagement with the interior walls of the tubular members and the insulated wires in watertight relation.
