A shielded connection line for a magnetic resonance tomography system includes a signal conductor, a shield for the signal conductor, and a plug-in connector. The plug-in connector has a large number of connection contacts that are arranged in a two-dimensional matrix and are electrically insulated from each other in the plug-in connector. The signal conductor is in galvanic contact with a first connection contact, and three second connection contacts adjacent to the first connection contact and surrounding the first connection contact are galvanically connected to the shield.

A connector and assembly of a cabling category and comprising two mating zones connected by an intermediate zone. Each of the zones is manufactured such that Near End Cross Talk (NEXT) resulting from transmission of the high frequency signal across each zone is below a specified amount chosen such that NEXT introduced by a high frequency signal transmission between via all the zones is below a level as specified for the cabling category.

A rotatable plug structure for a power adapter includes a carrying base, two conductive terminals and a plug. The carrying base includes a first installation slot, a second installation slot and a channel connected between the two. The conductive terminals are secured onto the first and second installation slots; the conductive terminals include a main body, a wiring portion and a clamping member. The clamping member includes a pair of metal slats bent from the main body and extended to taper toward each other. The plug is rotatably installed on the carrying base and the conductive terminal; the plug includes a pivotal axle, a pair of insertion pins and a conductive connecting end. The plug swings freely about the pivotal axle between a deployed state and a retracted state; thereby, the conductive connecting ends are clamped by the clamping member or disengaged therefrom to overcome the improper contact problem.

A sealed electrical plug comprises at least one temperature sensor for monitoring an internal temperature of the electrical plug. The electrical plug further comprises a data cable that is wrapped by a shield for screening electrical noise so as to accurately capture and convey temperature data. The electrical plug further comprises a housing or holder for receiving the at least one temperature sensor, wherein the housing is capable of being embedded within an inner-mold of the electrical plug and positioned close to at least one pin. One or more seals may be placed at junctions between the at least one pin and the inner-mold and a cable for the data cable to seal the inner-mold from air, moisture and particles.

An overheat-protection device with a cord that includes a transmission wire to transmit electrical power and a sensor wire to transmit a signal, a plug attached to an end of the cord, and a thermistor includable in the plug and connected to the sensor wire. The signal may be received and/or analyzed by a sensing device, which may control a switching device to open and/or close a power circuit. The thermistor may detect a level of heat, which may be communicated as a signal via the sensor wires. The signal may be definable by the thermistor varying a level of resistance to the signal responsive to the level of detected heat. The thermistor may be a NTC thermistor and may be constructed from a thermal plastic or a ceramic.

A wiring device including a face contact; one or more line contact arms; one or more load contact arms; and a fault detection circuit. The one or more line contact arms having an upper line contact located on a bent portion of the line contact arm, and a lower line contact located on a substantially straight portion of the line contact arm. The one or more load contact arms having a load contact located on a bent portion of the load contact arm. The fault detection circuit that detects a fault condition in said wiring device and generates a fault detection signal when said fault condition is detected, wherein said fault detection signal electrically disconnects the face contact from the upper line contact and the lower line contact from the load contact.

Example retainer apparatus and related methods are disclosed. An example retainer apparatus disclosed herein includes a post having a first end to be received by an opening of a wall plate cover of an outlet and a second end opposite the first end. At least a portion of the post has a plurality of grooves positioned between the first end and the second end. The plurality of grooves forming a retainer-receiving portion. A plug retainer is moveably coupled to the post. The plug retainer to slide along the retainer-receiving portion in a linear direction relative to the grooves when the plug retainer is moved relative to the retainer-receiving portion of the post.

A smart plug that is partitioned into a plurality of printed circuit boards (PCBs) in a three dimensional manner to reduce its size. Aspects consider the effect of the possible increased internal temperature as the size of the smart plug is reduced. For example, thick metal foils connect various components of a smart plug to reduce heat dissipation within the smart plug. Also, a metal foil may transfer heat from contact metal on a PCB to a side wall of a plastic housing of the smart plug. The smart plug may comprise a computing device that obtains information identifying the attached electrical device and accesses device data about the time duration during which the attached electrical device exhibits transient characteristics. The computing device then uses the accessed data to effectively control the attached electrical device.
