An electrical control system which controls an electrical device from two or more locations with independent control function, the system including a wall adapter having a first integrated circuit board, a first enclosure, and a second enclosure. The first enclosure includes a first push button, a first synchronizing push button, and a second IC board electrically connected to the wall adapter; and the second enclosure includes a second push button, a second synchronizing push button, and a third IC board. Each of the wall switch, the first synchronizing push button, and the second synchronizing push button is a system power control button and part of a synchronizing circuit that synchronizes the electrical control system to default system power controls upon being pressed by a user. Each of the first and second push buttons is a local button that controls a respective controlled receptable of a respective enclosure.

A printed circuit board is housed in a connector. A temperature sensor is mounted on the printed circuit board between two connection pads located on one of the faces of the printed circuit board. A contact housed in the connector is placed in thermal continuity with two thermal conduction lands, one of which is arranged on the same face of the printed circuit board as the connection pads and the other of which is arranged beneath the temperature sensor. Each of the connection pads is connected to a temperature measurement circuit.

A power adapter includes a housing, an electronic assembly and a protective assembly. The housing has a receiving cavity, and the housing is provided with at least one heat dissipation hole penetrating to the receiving cavity. The electronic assembly comprises a plurality of electronic elements located in the receiving cavity. The protective assembly comprises a connection portion connected to an outer wall of the housing and extending outward, and a protective portion connected to an extension end of the connection portion, the protective portion is spaced apart from the housing. The projection of the protective portion toward the housing covers the heat dissipation hole. The protective portion of the power adapter may shield the heat dissipation hole to prevent external dust from falling into the receiving cavity through the heat dissipation hole. Heat dissipated by the electronic assembly may be dissipated out through the heat dissipation hole.

A power adapter with a Lightning female socket includes a main body and a housing, a Lightning female socket and an adapter unit on the main body, the Lightning female socket being electrically connected to the adapter unit; the housing being provided with an opening communicated to the Lightning female socket, the housing being sleeved on an exterior of the main body, and making the opening correspond to the Lightning female socket; the adapter unit being capable of providing electrical energy directly or indirectly to the Lightning female socket and outputting voltage and current outwardly through the Lightning female socket. By designing a power adapter with a Lightning female socket, a charging device and system, communication with an external terminal device and charging to the outside is achieved through the Lightning female socket.

A connection assembly for connection to an audio device includes a connector module including a connector configured for electronic connection to a mating connector of the audio device and a releasable latch configured for retaining the connector module to the audio device, an actuator engageable with the connector module and being moveable to release the latch for removal of the connector module from the audio device, and locking structure configured to selectively resist movement of the actuator to release the latch.

A strap connector includes an insulating body, a conductive element, a locking member, a pressing block, and a strap connected with the pressing block. The locking member includes a main body portion and a locking elastic arm. The main body portion includes a top plate. The locking elastic arm extends from the top plate and is used for locking with a mating connector. The pressing block is slidable backwardly under the pulling of the strap, so that the pressing block presses the top plate downwardly, and then the locking elastic arm moves downwardly to realize unlocking. When the unlocking method disclosed in the present disclosure is performed, it is only necessary to ensure that the pressing block slides over the top plate, which improves the reliability of unlocking.

An EMC filter plug-in arrangement with an EMC filter to avoid or reduce electrical and/or electromagnetic interference caused by an electronic component, in particular an inverter of a refrigerant compressor. The EMC filter plug-in arrangement has an EMC filter, a plug-in housing formed for receiving the EMC filter and having electrical conductor contacts formed on the outside which are in electrical contact with the EMC filter, and a plug-in receptacle formed for arrangement with an electronic component into which the plug-in housing can be plugged in to provide electrical contact between the EMC filter and the electronic component.

An electrical household appliance includes electrical contacts. The electrical household appliance includes accesses to the electrical contacts for establishing an electrical plug connection.

An unauthorized connection detecting device to detect an unauthorized device connection at a connection part at which an electronic control unit mounted on a vehicle and an input and output unit are connected to each other is provided. The unauthorized connection detecting device includes a pair of connectors having one connector mounted on the electronic control unit and another connector mounted on the input and output unit, the pair of connectors being to be attached to each other, a protrusion or a conductor pattern formed on the another connector, a switch unit arranged on the one connector and to detect the protrusion or a conductor connection detecting unit arranged on the one connector and to be electrically connected to the conductor pattern, and an unauthorized connection identification unit to detect an unauthorized connection based on a state detected by the switch unit or the conductor connection detecting unit.

A semiconductor package includes a package substrate, a semiconductor chip on the package substrate, the semiconductor chip including a logic chip and a memory stack structure on the logic chip, a connector and a connector terminal below the package substrate, a molding layer that covers the semiconductor chip, the molding layer having a recess region on a top surface of the molding layer, a housing that covers the molding layer, and an air gap on the semiconductor chip, the air gap being defined by the housing and the recess region of the molding layer, and the molding layer separating the air gap from the memory stack structure of the semiconductor chip.
