A component assembly system includes a supporting profiled rail, a functional component, and a bridging module configured to electrically connect to the functional component. The bridging module includes a module retention device configured to hold the bridging module on the supporting profiled rail. The functional component is configured to partly seat onto the bridging module, and includes a component retention device configured to hold the functional component on the supporting profiled rail. A locking slide is configured to releasably fix a functional component to a supporting profiled rail. The locking slide is configured to positively engage around the supporting profiled rail.

A system includes (i) a module configured to be mounted on a panel and (ii) a clamp. The clamp includes a retaining section configured to receive and retain a threaded structure. The retaining section is also configured to be connected to and apply force against the module. The clamp also includes a contact section configured to contact the panel and apply force against the panel. The clamp further includes a connecting portion connecting the retaining section and the contact section. The connecting portion is configured to allow part of the threaded structure to contact the contact section in order to create the forces applied against the panel and the module. The connecting portion can be elastic such that a separation of the retaining section and the contact section changes as the threaded structure pushes against the contact section.

The locking actuator assembly includes an actuator supported for axial and rotational movement by the I/O module, the actuator movable from an unlocked position having a first end of the actuator extending from a housing of the I/O module to a locked position wherein a second end of the actuator extends from the housing. The second end of the actuator includes a flange adapted to pass through a corresponding slot in a surface of the I/O base such that when the actuator is rotated the at least one flange restricts withdrawal of the actuator from the slot in the I/O base.

There is provided a rail attachment apparatus for an electrical device in which a biasing elastic function is imparted to a slider itself, whereby the slider can be adjusted to be thin and the number of components can be decreased. The rail attachment apparatus includes a nipping portion that nips one side edge of an attaching rail fixed to an attaching surface of the electrical device, and a slider that is opposed to the nipping portion and slidably held at the other side edge of the attaching rail in a direction intersecting with this attaching rail. The slider is provided with integrally formed bending elastic portions which bias the slider in a direction to enable nipping the attaching rail.

An assembly of an electrical device includes: at least one electrical functional assembly which has a supporting element and electrical or electronic functional components arranged on the supporting element; a fastening device for fastening the electrical device to a higher-level assembly; a heat sink core element having at least one face wall; and an external element connectable to the heat sink core element. The heat sink core element forms a supporting structure of the electrical device on which supporting structure the fastening device is arranged. The external element is connectable to the heat sink core element such that the at least one electrical functional assembly is accommodated between the at least one face wall of the heat sink core element and the external element.

A standard track smart home system, comprising: a gateway device (1), a power interface of the gateway device (1) being respectively connected to a power supply live line (L) and a power supply zero line (N), the gateway device (1) remotely connecting to at least one user terminal, and the gateway device (1) being also used for connecting to a plurality of first expansion devices (10); and a standard track (T), the gateway device (1) and the plurality of first expansion devices (10) being arranged side by side on the standard track (T) and connected to one another by means of a plurality of wiring terminals, and outgoing interfaces of each of the first expansion devices (10) being respectively connected to one or more smart home devices.

An industrial controller with a modular backplane includes multiple modules, where each module includes a base and a chassis. Electrical connectors located on each side of the base engage the base of an adjacent module such that the bases are electrically connected. The backplane is defined by and extends through each of the bases connected to each other. A chassis is inserted into each base. Each chassis includes an embedded switch and a local circuit. The embedded switch is in communication with the base, and the local circuit performs the operation of the corresponding module. The embedded switch receives data transmitted along the backplane between bases. The embedded switch reads the data intended for the module and passes the data to the local circuit for further processing. Similarly, the embedded switch receives data from the local circuit and inserts the data on the backplane for transmission to the appropriate module.

A device for use in a building management system (BMS) is a controller device. The device includes a base comprising a first processor and a base interface, the first processor being configure to provide control operations for a device in the building system, and a first module installable on and removable from the base. The first module includes a first module interface for receiving power from and communicating with the base via the base interface. In some embodiments, the device includes an optional a second module installable on and removable from the base, the second module comprising a second module interface for receiving power from and communicating with the base via the base interface.

A carrier-rail bus assembly including a number of n mechanically contiguous bus-circuit-plate sections electrically connected via bus-circuit paths and installed in a carrier rail, an electronic control unit being configured such that it detects whether an apparatus is inserted in an installation position i, respective installation position i being allotted a bus address, which is assigned to the apparatus inserted on the carrier rail on the respective bus-circuit-plate section in respective installation position i. A related method for assigning a bus address is also disclosed.

A building controller may include a housing having a back plate and a mounting clip, which may be slidably disposed relative to the back plate between a wall mount position used when mounting the building controller to the wall, and a DIN rail mount position used when mounting the building controller to a DIN rail. When in the wall mount position, the mounting clip and the back plate may be configured to hold the mounting clip in the wall mount position until at least a first threshold sliding force is applied to the mounting clip. When in the DIN rail mount position, the mounting clip and the back plate are configured to hold the mounting clip in the DIN rail mount position until at least a second threshold sliding force is applied to the mounting clip.
