Abstract: An electrical socket and method of making an electrical socket. The socket includes a body that has spaced contact beams extending between the first and second ends and an inner receiving area for accepting a mating pin. The contact beams are configured for aligning into a hyperbolic geometry. Each of the contact beams has a middle section between first and second end sections. Each middle section has a pre-formed contour that defines a cross-section of each contact beam that defines a fully radiused, inner contact area without sharp edges such that each middle section extends further into the inner receiving area than the first and second end sections when the contact beams are aligned into the hyperbolic geometry and such that the fully radiused, inner contact areas of the contact beams are positioned for contact with the mating pin when inserted into the inner receiving area of the socket body.

Abstract: A flat plug-in connector assembly includes a flat contact, a mating plug connector, and a contact chamber. The flat contact has a middle strip having opposite first and second sides and further has a first end that forms a blade contact section. The mating plug connector includes a pair of contact springs for accommodating the blade contact section. The flat contact further includes first and second spring arms for damping relative movements between the blade contact section and the contact springs. The first and second spring arms are integrally formed in one piece at the first and second sides of the flat contact. The first and second spring arms have first and second free end sections in a form of first and second detent hooks. The flat contact is inserted in the contact chamber with the first and second detent hooks being displaceable supported in the contact chamber.

Abstract: A charging plug for charging a mobile terminal, includes a plug element for carrying current, and also includes a portion extending beyond the plug element. That portion is long enough to prevent the plug element from contacting the mobile terminal, if the mobile terminal requires a smaller current. However, the portion is short enough to allow the plug element to contact the mobile terminal if the mobile terminal is equipped to handle the current carried by the plug element. According to an additional embodiment, the portion extending beyond the plug element will provide the smaller current if the smaller current is required.

Abstract: A female electrical terminal has clamping segments 13 with contact faces 15A for tab-type terminals and contact faces 14A for pin-type terminals. A receiving segment 16 has a tab-type terminal contact face 15B and pin-type terminal contact faces 14B. The space between the tab-type terminal contact faces 15A and 15B forms a tab-type terminal insertion slot 17. The space enclosed by the pin-type terminal contact faces 14A, 14A, 14B forms a pin-type terminal insertion slot 19. Various configurations are disclosed.

Abstract: The female terminal (10) of the present invention is electrically connectable with both first and second male terminals 1a, 3a having different thickness. This female terminal has a tubular portion (11) in which either one of the first and second male terminals is inserted. In the tubular portion a common contact portion (13) for contacting in common with the first or second male terminal, and first and second individual contact portions (15, 16) are provided. The first individual contact portion (15) contacts with the first male terminal (3a), while the second individual contact portion (16) contacts with the second male terminal (1a). Either one of the common contact portion and the first and second individual contact portions is formed with a spring plate (12).

Abstract: A cable adaptor assembly is disclosed that allows any type of plug to be adapted to any type of socket. The arrangement consists of at least two cable members each having a plug and socket separated by an electric cord wherein the plug and socket on any given cable member are of distinct configurations. This assembly allows an operator to quickly adapt a given electric plug from an appliance to a particular wall outlet.

Abstract: A brush holder assembly for a commutator type electric motor includes a substantially circular base plate of insulating material having a central aperture for receiving the motor commutator.

Abstract: An adapter for a twist-lock extension cord in which the adapter replaces the female plug-end of the extension cord. The adapter has a face plate in which are formed three curved cutouts for receiving the three curved electrodes of a twist-lock male plug. There are also provided on the face plate two straight cutouts for receiving the two electrodes of a standard household male plug. One of the curved cutouts is ground, and also receives the ground of the standard household-type male plug. Three terminals are provided, one associated with the ground cutout, and each of the other two associated with a pair of one curved and one straight cutout. A clamp secures the exposed wires of the extension cord to the adapter for connection to the terminals, thereby converting the extension cord to one that receives not only twist-lock male plugs but also standard household-type male plugs.
