A docking station has a base, a main casing, a cover body, a ventilation layer, and multiple first lateral openings. The main casing forms a first inner space and has multiple first through-holes. The ventilation layer is in gaseous communication with the first inner space via the first through-holes. The cover body is fixed to the main casing, and the ventilation layer is formed between the cover body and the main casing. The first lateral openings are formed in the cover body and in gaseous communication with the ventilation layer. When in use, heat generated by electronic components inside the first inner space makes air inside the first inner space flow upwards to the ventilation layer and subsequently exits the docking station via the first lateral openings. Meanwhile, cool air enters the first inner space via the first lateral openings to dissipate heat.

A circular power connector that can accommodate plugs of varying diameters includes a plurality of electrical terminals that include a contact beam extending from and monolithic with base, where the contact beam includes a contact portion, and a mounting portion that extends from and monolithic with a base for mounting the terminal to a substrate. The terminals are cylindrically arranged to receive a plug. Alternatively, each electrical terminal includes a frame portion, a first contact beam extending from the frame in a first direction, and a second contact beam extending from the frame in a second direction. Multiple electrical terminals are oriented so that the first and second contact beams for one terminal extend at an angle, preferably perpendicular, to the first and second contact beams of another electrical terminal, in a still further embodiment, an electrical terminal having two halves is provided.

A charging connector includes a housing and a cover. The housing includes a normal fitting part and a quick fitting part. The normal fitting part has a normal frontage to which a normal charging connector is finable. The quick fitting part has a quick frontage to which a quick charging connector is finable. The cover is configured to close the quick frontage. The quick fitting part has a terminal insertion hole through which a terminal of the quick charging connector is insertable inside the quick fitting part. The cover has a first protrusion extending toward the terminal insertion hole and holding the cover on the housing with the first protrusion being inserted into the terminal insertion hole.

Today, building automation and infrastructure provisioning are discrete deployments and systems such that electrical power distribution for consumption, electrical power and switching for lighting, environmental sensors, security sensors and the like are discrete and fixed. The present disclosure provides receptacles including electrical power outlets and light switches with configurable and reconfigurable additional functionality such that additional functions are distributed as necessary or required within the environment such as sensors, wireless interfaces, and data interfaces through the use of removable inserts. Further, these receptacles and inserts support artificial intelligence-based assisted living functionality through monitoring user activities with the artificial intelligence centralized or distributed locally or remotely accessed. These receptacles and inserts identify other electrical or electronic devices attached to them, allowing increased knowledge of the user's activities, as well as providing additional aspects of artificial intelligence-based assisted living such as power monitoring, and preventive maintenance.

A new and improved intrinsically safe barrier (“ISB”) provides advantages in connection with installation of field equipment in hazardous areas including Division 2/Zone 2 areas. In one embodiment the new ISB provides a pluggable/unpluggable ISB for use with a receiving terminal base adapted for individual field mounting and alternatively for use with a circuit mount terminal base to permit direct mounting of ISB on circuit boards. A highly effective heat sink design and potting material allows for heat dissipation to allow the ISB to serve a wider range of applications.
