Disclosed is an electronic device that includes a first cover, a second cover opposite the first cover, a side housing disposed between the first cover and the second cover and including a plate disposed between the first cover and the second cover and a frame surrounding the plate and connected with the first cover and the second cover, a display disposed between the plate and the first cover, and a printed circuit board disposed between the plate and the second cover and including a first surface facing the plate, a second surface facing the second cover, and side surfaces provided between the first surface and the second surface, at least some of the side surfaces including plated areas. The plate includes a connection structure to which the printed circuit board is electrically connected, the connection structure includes a recess, the recess including a first sidewall, a second sidewall facing the first sidewall, a first conductive structure comprising a conductive material disposed on the first sidewall, and a second conductive structure comprising a conductive material disposed on the second sidewall, and at least part of the printed circuit board is disposed in the recess such that the plated areas contact the first conductive structure and the second conductive structure.

An electrical connection box includes: a frame main body; a lid assembled to the frame main body; a plate-shaped member sandwiched between the frame main body and the lid; and a bus bar which has a main body arranged on a surface of the plate-shaped member and a terminal portion bent from the main body toward the lid. The bus bar has a protrusion protruding from a side surface of the terminal portion. The lid has a bus bar holding portion into which the terminal portion is inserted. In the bus bar holding portion, a wall portion opposing the side surface of the terminal portion has a holding groove into which the protrusion is press-fitted.

A double-ended socket system for safely and easily seating a double-ended lamp is disclosed. The system has two socket assemblies spaced a distance corresponding to the length of a double-ended lamp. Each socket assembly has a housing with a recess that houses a cylindrical socket for receiving a lamp end that rotates between a disengaged orientation and an engaged orientation. The housing has an attached electrical connector connected to a power source. The socket has another attached electrical connector that contacts the electrical connector of the housing only when the socket is rotated to the engaged orientation, thus eliminating the electrical shock hazard of conventional double-ended socket systems. The lamp may be removed only while in the disengaged orientation. A user may install a double-ended lamp into the socket system by use of only one hand. A method of use of a double-ended socket system is also disclosed.

An electrical line coupling system is presented. The coupling system can include a string light system that includes a fastening system, fastening device, string light kit, coupling system, mounted coupling system, and/or connection apparatus. The coupling system can leverage components and/or designs of electrical lines (e.g., plugs, connectors, sockets, etc.) to facilitate coupling of the electrical line to an object and/or surface.

A flat and detachable electrical connection system between a flat lighting module and a lampholder is described. The flat lighting module comprises a lighting panel, control circuitry for controlling the lighting panel, and electrical contact pads connected to the control circuitry, all supported at least in part by a mechanical support plate; the mechanical support plate being at least partially enclosed in a housing with a provision or opening so that light can be emitted from the lighting panel; and where the mechanical support plate includes a male mechanical support connector section that extends out from the mechanical support plate in the same plane as the thickness of the lighting module; and where the male mechanical support connector section includes means for non-permanent locking or latching of the lighting module to the lampholder. The lampholder comprises a female mechanical connector into which the male mechanical support connector section of the lighting module engages and which includes means for non-permanent locking or latching of the male mechanical support connector section of the lighting module; and a male electrical extension that extends out from the female mechanical connector and which engages the electrical contact pads in the lighting module to supply electrical power or communication signals or both to the control circuitry when the lighting module and lampholder are connected. The lighting panel may be LED or OLED and the electrical connection system may be used in a luminaire or lamp.

A home security light bulb adapter includes a bulb connector having male threads, a bulb socket having female threads, a camera, sensors, a wireless communications interface, and a processor. When the bulb connector is connected to a bulb fixture, the camera and the bulb socket are switched on when the sensors sense a motion. The processor then sends data to a remote device over a network via the wireless communications interface.
