Abstract: An electrical plug removal device for use with electrical plugs of the type having an electrical cord, a cord cap or plug, and electrically conductive spaced apart blades or prongs, the electrically conductive spaced apart blades being plugged into an electrical outlet or receptacle. Many people remove an electrical plug from an electrical outlet by simply taking hold of the electrical cord and pulling on the electrical cord to remove the electrical plug from the electrical outlet. This action results in damage to the electrical cord or to the electrical plug itself that may lead to electric shock or electrocution of the person removing an electrical plug in this manner, or may lead to an electrical fire. The electrical plug removal device is constructed from thin non-conductive semi-flexible material designed to be used with a variety of electrical plugs having different types of cord caps and different shapes, configurations and numbers of electrically conductive spaced apart blades or prongs.

Abstract: An electrical connector assembly according to the current invention comprises a receptacle and a right angle header for connecting two or more printed circuit boards. A composite action beam is located in the receptacle and has a movable end and a fixed end. During an initial phase of the pin insertion cycle, the movable end of the composite action beam deflects so as to minimize the force necessary to insert the pin into the connector housing. During an intermediate phase of the insertion cycle, the movable end contacts an inside wall of the connector and the composite action beam functions as a two-end supported beam. The composite action beam supported at both ends exerts sufficiently high normal force against the inserted pin so as to retain the pin in the inserted position. Thus, the composite action beam reduces insertion force without compromising normal retention force once the pin is inserted.

Abstract: A female connector housing (10) is equipped with a rotating arm (20) which is flat with the housing (10) when the connection is complete, and is raised when the connection is incomplete. When a male connector housing (30) is inserted in the female connector housing (10), its protrusion (31) is pressed against the bottom surface (24) of the rotating arm (20) moving the rotating arm (20) away from the female connector housing (10). When the connection is accomplished, the rotating arm (20) returns to its original position against the female connector housing (10). Designated FIG. 2.

Abstract: A charger-side connector is moved toward a battery-side connector through the engagement of a positioning projection formed on the battery-side connector in a guide groove formed on the charger-side connector by rotating an outer tube. At this time, the outer tube is retained relative to an inner tube in predetermined positional relation by straight grooves and plunger mechanisms. The retaining positions are determined in accordance with conditions of connection between power and signal terminals of one connector and power and signal terminals of the other connector, and therefore the rotational condition as viewed from the outside indicates the connected condition of the terminals.

The slider is movable between a cable admitting position remote from the mouth and a cable connecting position adjacent the mouth, forcing the cable into electrical connection with the protuberances.

Abstract: An electrical connector has a first connector body which has a deflectable locking member with an engagement catch and a second connector with an opening for receiving the locking member and engagement catch. A coupling assurance device can be positioned in the first connector body and allow coupling of the first and second connector bodies, due to the flexibility of the locking member, and yet prevent unintentional decoupling of the first and second connector bodies unless the coupling assurance device is removed.

Abstract: An electrical connector is disclosed having a movable contact retainer that cooperates with the connector housing to either retain or release the contacts. The retainer in movable from a closed position where the contacts are secured in place with respect to the connector housing and to an open position where the contacts are free to be removed for repair or replacement. A latch mechanism is provided that is operable from outside of the connector to move the contact retainer to either of its two positions. The latch mechanism includes a latch lever having a raised surface that, when depressed flush with a surface on the connector housing by means of a tool and pushed in the appropriate direction, is made to move from its closed position to its open position.

Abstract: An electrical connector assembly (10) of the type having a pair of mateable cylindrical plug and receptacle shells (18,22) secured together by a rotatable coupling ring (16). The connector assembly is provided with a decoupling retardation mechanism which includes engageable teeth (34) on the interior of the coupling ring (16) and a pair of leaf spring members (46,72) mounted to the plug shell (18) inwardly of the teeth (34). The leaf spring member (46,72) includes a fixed beam portion (62,82) having a projection (64,84) which engages the teeth (34). The sides of the teeth and the projection are steeper on one side than the other. The steeper side is the one which is engaged when the coupling ring (16) is rotated in the direction to decouple the shells (18,22). Accordingly, greater torque is required to decouple the shells than to couple the shells.
