An electrical coupling device, such as a surge protector for a rail or other conductive structure, includes a pair of terminals, and a jumper for selectively electrically coupling and decoupling the terminals. Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure. In one embodiment, a threaded rod may serve as the jumper and in one position electrically couples the terminals and in another position electrically decouples the terminals and one end of the threaded rod becomes exposed for use as a test point.

A bridge is configured to electrically connect the cathode connector to the anode connector with a dispenser cover in a closed orientation and further configured to electrically disconnect the cathode connector from the anode connector with a dispenser cover in an open orientation.

A system, method, and apparatus for retrofitting a fluorescent light fixture accommodating an LED-based lighting system. A track is electrically connected to the driver module. The track includes at least one electronic conductor that is connected along the length of the track. At least one track adapter may connect to the track, and the track adapter includes a locking mechanism that allows the track adapter to connect to the track at any location along the track and the track may be removed. The locking mechanism may permit the track adapter to be removable. At least one light engine module can connect to the track and may also be removable.

The invention relates to a high-voltage device (14) for a high-voltage application. The high-voltage dev ice comprises an electrically insulating housing (15), having a housing cover (16) that covers a housing interior (18), and covering means (10) for at least one electrical terminal (34) or electrical region to be protected from touching, which covering means are arranged in the housing interior (18). The covering means (10) have a protective cover (26). The protective cover covers the electrical terminal (34) or the electrical region, can be locked in a closed position by means of at least one locking element (30) and can be transferred into an open position by means of an opening operation. The at least one locking element (30) for the protective cover (26) within the housing is designed in such a way that the release of the at least one locking clement requires a duration, the electrical terminal (34) or the electrical region having transitioned into a touching-safe state after said duration has elapsed following the opening of the housing cover (16) and following the interruption of the high-voltage circuit triggered by the opening of the housing cover.

The present invention discloses a modular socket panel which includes a bottom layer adapted to be fixed to an embedded case in a wall and adapted to be electrically connected to a power supply provided by the embedded case, and a surface layer adapted to be directly or indirectly connected to the bottom layer in a non-fastening manner. The surface layer provides a power socket, which is electrically connected to the bottom layer. The modular socket panel disclosed in the present invention enables a user to mount a middle layer and the surface layer onto the bottom layer or remove the middle layer and surface layer from the bottom layer without any tool, and also enables the user to mount different middle layers in the modular socket panel when needed to implement different functions, for example adding more intelligent functions.

An elastic-clip junction box structure has multidirectional wire insertion effect and holds the wires quickly. The junction box structure includes a case body and at least one conductive clip disposed in the case body. The case body is formed with a first-direction wire socket and a second-direction wire socket with different insertion directions. The conductive clip has a first-direction clip mouth in communication with the first-direction wire socket and a second-direction clip mouth in communication with the second-direction wire socket. In use, the wire can be selectively inserted into the first-direction wire socket or the second-direction wire socket. Alternatively, wires can be respectively inserted into both the first-direction wire socket and second-direction wire socket. Accordingly, wires can be selectively inserted into the elastic-clip junction box structure in multiple directions and quickly and securely held by the first-direction clip mouth and second-direction clip mouth or released therefrom.

An electrical meter quick connect device has a housing with open faces. A first face is configured with connectors to mate to a electrical service panel in a meter connection manner, and a second face is configured with connectors to mate to a meter in an electrical service panel connection manner. First and second set of lines are within the housing, connected from the first face to the second face. A breaker switch is on the housing and coupled to at least one of the first and second set of lines. A third set of lines is connected to the breaker switch and exits a side of the housing, the third set including a ground line. An electrical vehicle charging line is coupled to the third set of lines. The device can be inserted between a meter and electrical service panel to provide an electric vehicle power connection.

A charging device is provided. The charging device includes an output terminal unit connected to an input terminal unit of a battery pack. The output terminal unit includes a terminal body including an output terminal connected to the input terminal unit and a terminal cover which covers the output terminal before the input terminal unit of the battery pack is connected to the output terminal unit and through which the output terminal passes while the input terminal unit of the battery pack is connected to the output terminal unit.

A connector 10 disclosed by an embodiment includes a cover (service cover 20) having a cover housing 21 and a cover connector 40, the cover connector 40 being integrally provided to the cover housing 21, and a device-side connector 50 having a receptacle 52, the cover housing 21 being fittable into the receptacle 52, a mating connector 60 configured to close an interlock circuit by being connected to the cover connector 40 being disposed inside the receptacle 52. The cover housing 21 includes preceding guide portions 27 configured to guide the cover connector 40 into a proper posture to be connectable to the mating connector 60 by sliding on an opening edge part 56 of the receptacle 52 prior to the connection of the cover connector 40 and the mating connector 60.

A battery pack includes a case, a first set of battery cells and a second set of battery cells received in the case, a circuit board, and a main power output interface. The first set of battery cells and the second set of battery cells can be connected in series or in parallel, and output two kinds of working voltage through the main power output interface. The battery pack further includes an extended power output interface and a switch provided between the first set of battery cells and the second set of battery cells. The battery pack can output a third voltage for an external device through the extended power output interface when the first set of battery cells and the second set of battery cells are connected in series through the switch. It's safe and reliable when charging the external device.
