A fail proof electrical connector apparatus offers a unique structure for solar photovoltaic (PV) system installations. The apparatus includes a compact connector enclosure that can be installed at flexible locations of a solar module. The tabs of the connector enclosure connect to various solar cells of the module. The insertion pins of the tabs are mounted inside plugs of a pin connector, which connects to a cable. The cable comprises a one-plug end and a multiple-plug end with a wire connecting both. Of the two or more plugs of the multiple-plug end, only one active plug is electrically connected to the wire. The cable is connected to the module with the active plug being inserted to a center plug of the pin connector, and the one-plug end connected to an outer plug of the pin connector of an adjacent module, thus, achieving fail proof, reliable installations while saving labor hours.

An adapter includes a socket portion and a power-taking portion. The power-taking portion is connected to a bottom of the socket portion, and the power-taking portion is configured to enter an electrified guide rail to take power. The socket portion includes a socket portion body, a fixed support, a locking member and an unlocking member. The fixed support is disposed at a bottom of the socket portion body. The locking member runs through the fixed support, and the locking member is configured to be limited within the electrified guide rail in a locked state and to be released from the electrified guide rail in an unlocked state. The unlocking member is connected to the fixed support, and the unlocking member is configured to enable the locking member to be switched between the locked state and the unlocked state.

Provided is a battery charging system for charging an internal battery of a jump starter device, including a universal serial bus (USB) connector for receiving power from a direct-current (DC) port of a vehicle, a voltage detection circuit configured to detect a voltage of a vehicle battery, and a USB driver configured to control charging power from the USB connector to the internal battery of the jump starter device based at least in part on the detected voltage of the vehicle battery.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.
