The present disclosure relates to an adapter for a 2-wire field device, especially a 2-wire field device of process and/or automation technology, comprising a communication unit for, especially wireless, especially bi directional, communication with an external unit, and an energy storage unit for supply of at least the communication unit with electrical energy. According to the present disclosure, the adapter includes a first connection element for, especially electrical, contacting of the adapter with a second, first connection element complementary, connection element of the field device, wherein the at least two connection elements are embodied for supply of at least the adapter with electrical energy and for exchanging information. Furthermore, the present disclosure relates to a transmitter with an adapter of the present disclosure as well as a 2-wire field device having an adapter of the present disclosure or a transmitter of the present disclosure.

The present disclosure provides a high-voltage isolating device and method. The high-voltage isolating device includes a power module and a shelf. The power module's back panel is provided with a first connecting portion, and the power module's front panel is provided with a first fastening member. The shelf includes a module slot for accommodating the power module. The module slot's rear end is provided with a second connecting portion, and the module slot's front end is provided with a second fastening member. Wherein in a first status, the first connecting portion is matched and connected with the second connecting portion, and the first fastening member is away from the second fastening member, and in a second status, the first connecting portion is disconnected from the second connecting portion, and the first fastening member and the second fastening member are matched and connected together by a padlock.

An adaptor plug assembly includes an adaptor plug and a mobile device which has a receiving unit. The adaptor plug includes a housing having a first connection end from which two terminals extends, and a second connection end in which three receptacle holes are defined. The two terminals are connected to the second connection end. A coil is mounted to one of the two terminals and electrically connected to a micro controller which includes a calculating unit, a transforming unit and a wire-less transmitting unit. The transforming unit receives current inducted by the coil and transforms the current into a first signal which is sent to and calculated by the calculating unit to be a second signal which is transmitted by the wire-less transmitting unit to the receiving unit of the mobile device. A power unit is installed in the housing provides power to the micro controller.

The present invention provides a battery clamp, comprising: a first and second wire clamps and a control device. Each of the first and second wire clamps is electrically connected to the control device. The control device comprises: a housing; a master-control board mounted within the housing; and connectors disposed at one side of the housing, and being electrically connected to the master-control board, comprising: at least a first and second electrode connectors, which are connected to an external power supply for receiving power, and at least one communication connector connected to the external power supply for building a communication connection between the battery clamp and the external power supply. The battery clamp is communicatively connected to the external power supply by the communication connector, thereby effectively solving the problems of a lithium battery in an external power supply e.g. battery bulge or explosion resulted from improper uses.

An electrical connector body is provided includes first and second housing portions formed from molded plastic. The housing portions include first and second interface surfaces that are configured to butt against one another to define a housing and one or more electrical components are disposed within an interior of the housing. The one or more electrical components may comprise connectors of a male or female cord cap, an in-line surge suppression circuit, and/or a compact automatic transfer switch. In one implementation, each of the first and second connector body portions may include a strain relief extension for engaging an electrical cord and a compression member (3691) may be disposed over the strain relief extensions to secure together the first and second connector body portions. The compression member may be selected from a set of compression members based on a size of the electrical cord.

A surge protector is configured to protect Ethernet equipment from an electrical surge. The surge protector includes an Ethernet cable input portion structurally configured to receive an Ethernet input cable, an Ethernet cable output portion structurally configured to receive an Ethernet output cable to connect to an Ethernet device, a ground plug portion having a dummy portion and a ground portion, and wherein the ground portion is structurally configured to connect to an electrical wall outlet so as to direct an electrical surge on the input Ethernet cable to a ground of the electrical wall outlet so as to protect equipment that is electrically connected with the output Ethernet cable from the electrical surge.

The present invention effectively prevents a short circuit from occurring between a power supply terminal and a ground electrode. In a plug-side connector (1), a first protection element (first capacitor 16a) is provided between a metal plate (center plate 12) and a ground electrode (11a) and a second protection element (second capacitor 16b) is provided between an outer jacket (15b) of a cable (15) and the ground electrode (11a), inside a shell part (23).

A controlled-power RJ45 socket includes a housing having a cavity to receive an RJ45 plug. The socket further includes electrical contacts positioned in the cavity and that come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket. A switch is positioned to disconnect the power to the electrical contacts of the RJ45 socket before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during a de-mating of the RJ45 plug from the RJ45 socket.

A connector module for a modular plug connector is provided having an overvoltage protection with at least one earth connection. A connector and a modular plug connector having a connector module of the above type is also provided.

A surge protector that can be mounted in a standard electrical enclosuresuch as a double gang enclosure. The surge protector includes one or more removable surge protection modules. The surge protection modules are accessible through the front of the surge protector. The removable module can be removed and replaced without dismounting the surge protector.
