A junction connector assembly integrated with a fuse may include an inner housing having a 1-1-th bus bar, a 1-2-th bus bar, and a second bus bar disposed therein to be spaced apart from one another and a first opening portion formed on one side surface to protrude first terminal portions of the 1-1-th bus bar and the 1-2-th bus bar; and a fuse configured to electrically connect the 1-1-th bus bar and the 1-2-th bus bar to each other, the fuse being inserted and fixed into the first opening portion.

A connector includes: a first connector including a first main terminal; a second connector including a second main terminal and a boss having a protruding shape; and a fitting detection circuit configured to detect fitting of the first connector and the second connector. The first connector further includes a rotatable lever used for a fitting operation to the second connector and a fitting disengagement operation from the second connector. The lever includes a lock configured to lock, when the lock contacts the boss in the fitting disengagement operation, a rotation of the lever in a state where the fitting is not detected by the fitting detection circuit and also in a state where the first main terminal and the second main terminal are connected.

An electric plug having a switch for coupling a cable to a source of electric power. Electrically conductive prongs are configured to be coupled to the source of electric power when conductive prongs are inserted into an electric power outlet. A switch disposed within the plug electrically couples the plurality of prongs to the cable only after the prongs are electrified by the source of electric power.

A power supply system includes a housing comprising internal power circuitry; a receptacle panel removably coupled to the housing; and a circuit interrupter, such as a circuit breaker or fused disconnect switch, held in the housing. The circuit breaker includes a switch handle that is externally accessible and configured to allow a user to translate the switch handle between OFF and ON positions, the OFF position associated with electrical isolation of the power receptacle panel from a power output path between the receptacle panel and the internal power circuitry. In the OFF position, even when the power supply system is in an ON state, the receptacle panel is in electric isolation from the internal power circuitry and de-energized to thereby allow a user to remove the receptacle panel to thereby allow a hot swap with another receptacle panel.

A power distribution system includes a bus plug having an electrical switch configured to selectively control energization of the bus plug. The bus plug includes an electrical switch having a control knob operable to selectively control energization of the bus plug, and an actuator having an actuator adaptor coupling that couples movement of the actuator to the control knob. The bus plug includes a partition wall separating the internal volume into a line side and a load side. The bus plug includes an external handle coupled to mechanical linkages, and an adaptor bracket fixed to at least one of the mechanical linkages and oriented to interact with the control knob. The bus plug includes an actuator operable to move the mechanical linkages. Methods of controlling energization of a bus plug with a remote application and communication module configured to operate an actuator are also provided.

A power conversion device is provided for supplying power to an electronic device. The power conversion device includes a power supply connector, a voltage conversion circuit, a switch circuit and a detection circuit. The power supply connector is configured to couple with the electronic device. The voltage conversion circuit is configured to provide a suitable voltage level for the electronic device. The switch circuit is coupled between the voltage conversion circuit and the power supply connector. When the power supply connector is coupled with the electronic device and a ground pin of the power supply connector is fully shielded, the detection circuit configures the switch circuit to be conducted for supplying power to the electronic device.

A connector includes a first and second connector housings, a first and second terminals provided in the first and second connector housings, the second terminal including contact pieces with a gap therebetween, the gap being larger than a width dimension of the first terminal. The second connector housing includes pressing plate portions. The second terminal is to be accommodated between the pressing plate portions, the second terminal being displaceable between a first position and a second position, a part of the contact pieces extends beyond distal ends of the pressing plate portions when the second terminal is in the first position, the part of the contact pieces are completely retracted into a space between the pressing plate portions when the second terminal is in the second position. The contact pieces are to be pushed such that the contact pieces contact the terminal plate portions.

The charger includes first and second connectors, each including an opposing surface. One of the opposing surface of the first connector and the opposing surface of the second connector includes, on a first opposing surface, a male power terminal and a male signal terminal for a power cutoff signal projecting from the first opposing surface, and the other one of the opposing surface of the first connector and the opposing surface of the second connector is provided with a female power terminal which the male power terminal is to be fitted into and a female signal terminal which the male signal terminal is to be fitted into on a second opposing surface. A length of the male signal terminal in a direction in which the male signal terminal projects is shorter than a length of the male power terminal in a direction in which the male power terminal projects.
