Abstract: Inner and outer helically wound wire tension members (26, 28) are expanded into the cone (38) of cup body (32). Epoxy plug (40) is poured therein. When tension is applied, plug (40) slides within its cup (34) to compressively lock the tension members in the plug. Bosses (42, 44) are formed on the cup and cable sheath (30) and flexible sleeve (50) is sealed to both bosses. This provides sealing during stretching with increased tension.

Abstract: A child-proof outlet cover includes a base mountable over an electrical outlet faceplate and a pair of caps attached to the base with flexible strips. The caps are retained in the closed position on upstanding walls around openings in the base, which provide access to the outlet sockets.

The connector housing is preferably molded of a relatively rigid plastic and includes means for retaining the sealing members locked in place within the cavities.

Abstract: The cable of this invention comprises a pair of solid, flat, flexible electrical conductors of beryllium-copper attached to a reinforcing webbing of braided nylon. The ends of the conductors are soldered to electrical connector sockets and pins which are supported by glass reinforced resin disks. The webbing is tensioned while being molded inside a water impermeable elastomer which also encompasses the conductors, disks, and end portion of the sockets and pins. A second molding operation covers the water impermeable elastomer with a tough elastomer to form the cable including integral connector bodies incorporating the sockets and pins.

Abstract: A connector for making connections to the post of an automotive lead-acid battery is disclosed. The connector includes a body portion having a pair of bifurcated ring portions each defining a circular opening therethrough, and a locking ring portion, also defining a circular opening therethrough with a pair of lugs affixed to the locking ring. The circular openings of each are designed to slip over and surround the battery post and when the locking ring is turned by means of the lugs, the lugs come into contact with the ring portions of the body causing the three rings to cut into the battery post around its total circumference by cam action and to lock in position by friction.

Abstract: A terminal pin extends through a first housing portion and has a flange. A hard bead having a high melting temperature is disposed on the flange. At least one layer of insulating material is disposed on the bead and is provided with a lower melting temperature than the bead. A second housing portion is attached to the first housing portion as by welding to define a housing. The layer of insulating material is melted and the terminal pin is pressed in a direction, while the layer is molten, to eliminate any air pockets in the layer and to provide for a hermetic sealing of the layer of insulating material to the bead, the terminal pin and the housing. Instead of a single layer of insulating material, at least a pair of insulating materials may be used. These layers may have melting temperatures less than the bead and the layer closest to the bead may have a higher melting temperature than the layer removed from the bead. The assembly of the connector may be accomplished by the rotation of a turntable.
