A shielded electrical connector usable in conjunction with a household electrical appliance such as a cordless iron. The connector comprises a plug and a socket, the socket having a movable baffle which is held closed when the plug is not engaged with the socket, to isolate the socket's electrical contacts behind a shield section of the baffle. The socket also has a baffle arm, isolated from the shield section of the baffle, by which the baffle may be opened. The plug bears a projection which engages the baffle arm as the plug engages the socket. The socket also has an electrical switch which activates the socket's electrical contacts after the plug is substantially engaged with the socket.

A descrambler or decoder for premium scrambled television signals compares the tier of the received signal with the contents of a memory associated with the descrambler. The memory of each descrambler establishes the tiers which are to be decoded according to what the user of the descrambler has requested or paid the system operator for. The memory is in the form of a small plug which mates with a receptacle which is coupled to a tier comparator within the descrambler. The memory plug includes a predetermined circuit for each tier arrangement which a user or subscriber may request. Due to its small size and physical arrangement, the tier-establishing memory is resistant to tampering by the user, thereby preventing access to premium programming by unauthorized subscribers.

Circuit transfer apparatus is described for use in transferring from time-responsive control to temperature-responsive control, and vice-versa, in a microwave oven. The low cost, miniaturized apparatus is mounted to the wall of the oven's cooking cavity and is operated from within the cavity by insertion or withdrawal of the cable plug of the heat-sensitive food probe. The probe plug cooperates with insulative elements to activate spring-leaf sheet metal contacts mounted in the housing of the apparatus, to thereby effect the circuit transfer. The housing also serves as mechanical retention means for the probe plug.

An electrical connector structure is disclosed having low, or zero, insertion force interengaging terminals which do not engage initially as the connector mating portions are moved together, but which are automatically moved into engagement as the mating portions are moved into their fully mated position. This automatic engagement results from a lever, or cam, effect which converts relative telescoping motion of the mating portions into relative lateral motion of the low insertion force terminals therein.

The plug-switch includes a pair of terminal blades projecting outwardly of a housing for insertion in an electrical socket, and first and second pairs of contacts. A carrier member, which is movable within the housing between first and second positions, is normally biased to its first position by spring means and is movable from its first position to its second position by engagement with a member associated with an electrical socket. A pair of contact members, which are carried by the carrier member, serve to bridge either the terminal blades and one pair of the contacts or the terminal blades and the other pair of the contacts.

A safety feature in the form of a disconnect element for an electric socket structure is disclosed. The socket structure is formed of plastic material which is shaped to lock into openings provided to support and locate electric lights in automotive vehicles or the like. A separate ground element is employed with each socket to enable completion of an electric circuit. The safety feature forms a part of the ground element and automatically disconnects the ground element from the source of power in the event a lamp socket falls from, or is removed from, its respective opening.

An output adapter intended for use with electricity distribution tracks provided with exposed track conductors has an on-off switch and a resilient clamp which can be moved outwardly from the adapter to engage a track and lock the adapter thereto in a position in which the contacts of said switch can be moved to the ''''on'''' position in abutment with the track conductors.

In a tape recorder provided with a power jack which includes a rod-like conductive member, a relay conductive member insulated from the rod-like conductive member, and an elastic conductive member having elasticity and being capable of moving a first position, at which the elastic conductive member is separated from the relay conductive member by inserting a plug to the power jack, and a second position, at which is in contact with and electrically connected to the relay conductive member, a main switch for the tape recorder comprises a cylindrical rotary member having an inner periphery, an outer periphery and a recess formed in the outer periphery. The rotary member is adapted to snugly fit on the rod-like conductive member of the power jack when inserted thereinto, and is rotatable on and about the rod-like conductive member between a first position, at which the outer periphery and the elastic conductive member are in contact with each other and the elastic conductive member is located in the first position, and a second position, at which the recess corresponds to and face the elastic conductive member to locate the elastic conductive member in the second position.
摘要:
An electrical housing and switch box are provided, in which the housing is provided with a first opening through which wires are brought to the interior thereof, and a second opening adapted to receive the switch box. A plurality of contacts are mounted in the housing adjacent the second opening. The switch box is provided with a plurality of connectors adapted to slide into and engage with the contacts to provide an operative assembly.
