A dual connector system includes a host circuit board with first and second electrical connectors. The first electrical connector has a housing with a card slot, first contacts and a latching feature. The second electrical connector has a housing with second contacts. The dual connector system includes a dual connector module having a module circuit board having contact pads. The dual connector module has a latch movable between a latched position and an unlatched position. The latch engages the latching feature of the first electrical connector in the latched position to hold the dual connector module in a mated position. A release mechanism is operably coupled between the dual connector module and at least one of the first electrical connector and the second electrical connector. The release mechanism forces the dual connector module to an unmated position after the latch is moved from the latched position to the unlatched position.

A connector includes a housing and a multi-layer peripheral structure disposed on the housing. The multi-layer peripheral structure is configured to enclose one or more pins and to expand in response to exposure to a liquid for disconnecting the connector from an electronic component without user intervention. The multi-layer peripheral structure may include an outer layer that may include a permeable material, a middle layer disposed within the outer layer, where the middle layer may include a material that expands when wet, and an inner layer disposed within the middle layer.

A power line disconnect apparatus includes a housing; an electrical connector that projects from a surface of a connector plate coupled to the housing, the electrical connector configured to receive a plug of a power cable; an ejector pin configured to project through a first aperture in the connector plate and eject the plug from the electrical connector; a microswitch configured to activate and deactivate a power circuit associated with the power cable; and a sensor pin configured to project through a second aperture in the connector plate, the sensor pin having a sensor pin extension, the sensor pin extension configured to control the microswitch.

A power cord disconnect apparatus and methods of disconnecting a power cord. An ejection mechanism may include a scotch yoke assembly, the scotch yoke being reciprocatable to engage and eject a power cord plug out of a receptacle. The apparatus may include a power circuit with a normally-open first switch closing in response to the plug being inserted into the receptacle and a normally-closed second switch opening in response to a signal, power being transferred between the power cord and the power circuit when the first switch and second switch are closed, power being prevented if either the first or second switch opens.

Provided is a plug for use as a disconnector for current transformers. Two types of short circuits are provided in the plug. A first short circuit is used for diverting overvoltages by short-circuiting the electrical contacts in the plug. A second short circuit is provided for short-circuiting electrical contacts in the plug when the plug is not contacted. The short circuits are designed in such a way that the first short circuit is used as a fuse when the second short circuit fails.
