Thermal mitigation features may be included in a Universal Serial Bus (USB) cable assembly or in the USB receptacle portion of a device. In one aspect, one or both ends of a USB cable jacket may have greater thermal conductivity than the portion between them. The portion having the greater thermal conductivity may dissipate excess heat from the cable into the environment. In another aspect, a USB cable connector or the USB receptacle portion of a device may include a thermoelectric heat pump. The thermoelectric heat pump may move excess heat from the cable assembly or receptacle into a portion of the cable assembly or device that dissipates the heat into the environment.

A component for an electrical connector, comprising a housing and a plurality of electrical contact elements, the ends of which are accessible at one end of the housing for connection to a mating connector component. The electrical contact elements are arranged in at least two segments which are separated from and shielded against each other. The outer contour of each of the at least two segments has at least two legs and a base side extending from one end of one leg to one end of the other leg, at least one leg of each segment forming an interior angle of 30° to 80° or 100° to 150° with the base side. The segments are arranged in a row with a shielding being provided between the legs of neighbouring segments.

A housing of a connector includes a first section and a second section connected to the first section and extending from the first section. The first section has a first dielectric constant. The second section has a second dielectric constant that is less than the first dielectric constant.

The invention relates to a kit of parts comprising DC, low voltage system of an elongated track and a plug. The elongated track has a first and a second end and comprises an elongated slot formed by a central groove with at least one shielded lateral groove, both grooves lying in a plane P. Typically two electric conductors are accommodated in said at least one lateral groove. A connector portion of the plug having a connector cross section which matches with a cross section of the slot. Both said slot cross section and connector cross section are asymmetrical with respect to a plane Q extending over the length axis perpendicular to plane P, and at least one of the slot cross section and connector cross section is mirror symmetrical with respect to said plane P. The symmetric and asymmetric requirements posed on both the cross section of the elongated track and the connector portion of the plug ensure that the connector portion only being insertable into the first end in the axial direction and, after a rotation of 180° over its connector axis, only being insertable in the axial direction into the second end of said track, with maintenance of the correct polarity The invention further relates to a plug suitable for use in the kit of parts according to the invention.

The present disclosure provides an electrical plug including a first temperature detection element and a second temperature detection element. When the processor determines that the temperature of the contact pins is greater than or equal to a temperature threshold according to a first detection signal outputted by the first temperature detection element and a second detection signal outputted by the second temperature detection element, the processor disables the electrical plug to transmit the input power to a load. When one of the temperature detection elements fails, the electrical plug determines whether the temperature of the electrical plug is greater than or equal to the temperature threshold according to the other one of the temperature detection elements. The electrical plug meets the redundant design required for functional safety to avoid unexpected hazards caused by the failure of a single temperature detection element. Therefore, the stability of the electrical plug is enhanced.
