Abstract: A latching insulated electrical connector apparatus has a first electrically insulating housing having a plurality of abutting electrical insulating members mounted therein and having an electrical contact mounted between each pair of adjacent insulating members. The first housing has a hinge cutout therein. A second electrically insulating housing has an open end and a plurality of protruding electrical contacts mounted therein, each of which aligns with one of the electrical contacts mounted between each pair of insulating members. The second housing has a hinge pin attached thereto across said open end thereof and a pair of locking lugs thereon. The hinge pin is positioned to align with the first housing hinge cutout and one of the locking lugs.

Abstract: The present invention is illustrated in one form as an inline electrical circuit breaker system for an electrical extension cable comprising an intermediate coupler having opposite end terminals adapted for electrically coupling a female terminal of a first electrical cable to a male terminal of a second electrical cable. A recess is formed in the coupler and has a pair of opposite end walls, the recess being adapted for receiving a circuit breaker. A first power bus segment extends from one of the opposite end terminals through an adjacent one of the opposite end walls and partially into the recess. A second power bus segment extends from another of the opposite end terminals through an adjacent one of the pair of opposite end walls and partially into the recess. The circuit breaker includes terminals for coupling the first and second power bus segments for establishing a current path through the coupler when the breaker is installed in the recess.

Abstract: A connector for electrical cables having a mechanism to prevent inadvertent disconnection. The connector includes a substantially solid block female component having a housing containing a concave, surface of revolution, curved surface with a plurality of electrical contacts on that surface and a substantially solid block male component having a housing containing a convex, corresponding surface of revolution, curved surface with a plurality of electrical contacts on that surface. One of those housings includes a pin spaced from and substantially parallel to the axis of the surface of revolution. The other housing typically has a pair of spaced notches in the housing at a corresponding distance from and substantially parallel to the axis of its surface of revolution. Thus, the notches can be engaged with the pin and the housings relatively rotated to bring the concave and convex surfaces and their associated electrical contacts into a wiping engagement.

Abstract: Disclosed is an apparatus and a related method for removing sand, trash and other materials from a spa, pool, aquarium or other fluid bodies and which includes a hollow, generally tubular member with an exhaust opening along the tubular member near the bottom end for venting fluid, and with a fabric bag fixed over the exhaust opening for passing the fluid but retaining the recovered material. One-way valve near the bottom end and in the exhaust opening ensure that fluid flow passes only upwardly through the tubular member and thereafter out of the exhaust opening.
