A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

A connecting element for mounting an electrical circuit board to an electrical flat conductor, in particular a busbar, has a flat or substantially flat mounting surface for applying and mounting the connecting element to the circuit board, and a tulip contact for receiving the flat conductor in an electrically contacting manner. The tulip contact includes at least one clamping element and a support element, between which a receptacle for the flat conductor is provided, and wherein the tulip contact preferably extends at a mounting angle greater than 45° and less than 135° with respect to the mounting surface. An electrical circuit board having such a contact element, a terminal block having such an electrical circuit board, and a method for automated mounting of such a terminal block are also provided.

A safety ground terminal apparatus can include a ground terminal operable to switch between a common ground connection or a isolated ground connection, wherein the ground terminal comprises a hinge point that is connectable to a base of a housing via a rail in an arrangement that allows for a disconnection from the common ground connection when the isolated ground connection is required and without compromising electrical contact. The ground terminal can provide a watertight ground connection irrespective of the type of ground connection requirement. The common ground connection or the isolated ground connection can be achieved without any additional parts assembled.

Electrical connectors, electrical modules, and systems are provided. In one aspect, an electrical connector includes a housing defining a side surface, an electrical conductor supported by the housing and including an engagement portion proximate the side surface of the housing. The engagement portion is adapted to engage another electrical conductor of another electrical connector. The connector also includes a magnet supported by the housing proximate the side surface of the housing, a projection extending from the side surface of the housing, and a receptacle defined in the side surface of the housing. In other aspects, an electrical module includes at least one of these electrical connectors. In further aspects, a system includes a plurality of these modules and the modules are selectively couplable together.

A terminal row for a terminal device, which can be attached to an electronics housing in an insertion direction and which can be connected to an electronic component that is to be accommodated in the electronics housing, has a predetermined number of single electrical conductors or connectors connected thereto to produce a connection between the single electrical conductors or connectors and the electronic component. The terminal row includes a plurality of main housings, at least two of the plurality of main housings being different, wherein the main housings are separate from one another in a pre-assembly state and configured to be attached to one another in a row direction to form the terminal row.

The building electrical wiring system includes a component box to attach to a wall frame, and a current plate configured to be mounted at a back of the component box having a plurality of receiving slots corresponding respectively to hot, neutral and ground. A component device, such as a switch, includes internal component circuitry terminating in a plurality of conductor stems to insert into a respective receiving slot of the current plate. An electrical jumper bar includes an insulated conductor extending between opposite ends which include a respective prong for each conductive path and configured to electrically couple the current plate to another current plate associated with another component device.

An electrical connection jumper is of the screw type for terminal blocks of switchboards. The jumper includes conducting body including at least two sub-bodies, each with a shape substantially in the form of an overturned “U”, insulating body including at least two sub-bodies with a substantially parallelepiped shape made of suitable insulating material, connected together longitudinally by a vertical membrane with a reduced thickness in the transverse direction. Insulating body has a plane for coupling with the conducting body. The coupling plane includes, between each sub-body and adjacent sub-body, a pair of arched lugs arranged opposite each other in the transverse direction and extending in the longitudinal direction so that the respective vertical arms are respectively connected to each one of the adjacent sub-bodies. Each arched lug has a tooth extending in the transverse direction towards the inside of the insulating body in empty space between the two sub-bodies.

Apparatus and associated methods relate to a quick-connector conversion system having a front cover and a rear module. In an illustrative example, the front cover includes apertures from which a plurality of connector ports extend through. Each connector port of the plurality of connector ports is in electrical communication with a first communication module. A rear module includes a second communication module electrically connected to a plurality of input/output (I/O) terminals such that when the front cover aligns with the rear module, the first communication module pluggably connects to the second communication module. When the first communication module and the second communication module are pluggably connected, the plurality of connector ports electrically connects to the plurality of the I/O terminals.

A safety ground terminal apparatus can include a ground terminal operable to switch between a common ground connection or a isolated ground connection, wherein the ground terminal comprises a hinge point that is connectable to a base of a housing via a rail in an arrangement that allows for a disconnection from the common ground connection when the isolated ground connection is required and without compromising electrical contact.
