A modularly expandable enclosure including a top end plate, a bottom end plate, and one or more elongated tray modules. The top end plate, the bottom end plate and the tray modules define an interior space of the enclosure. Opposite vertical ends of each tray module define an upper end connecting portion and a lower end connecting portion. The upper end connecting portion is configured for engagement with the top end plate and further configured for engagement with a lower end connecting portion of a vertically upwardly adjacent module tray. The lower end connecting portion is configured for engagement with the bottom end plate and further configured for engagement with an upper end connecting portion of a vertically downwardly adjacent tray module.

An automatic switching interface box for generators in residential dwellings and small commercial applications provides a breaker box transfer switch for generators powering one or more electrical loads. In power blackout situations, the breaker box transfer switch uses a power control relay to keep the load power on, which eliminates the need for a hot generator plug, because the plug in box is not powered. The generator power output cord is plugged onto the male plug of the interface box, or hard wired thereto. If the auxiliary generator had been started and is at rated voltage, the load is immediately and automatically switched from the utility connection to the generator as electrical source. The relay keeps the prongs of the male plug safely unpowered until the generator is attached since the relay coil is powered by the generator output and the plug is connected to the normally open contacts.

Various components and subcomponents of a pluggable modular system for electrical junction boxes are described herein. In various embodiments, a jbox interface chassis is configured to be wired and fastened within an electrical junction box to provide a hot-swappable pluggable interface between the wires in the electrical junction box and each of a plurality of hot-swappable pluggable modular devices. The jbox interface chassis may include a front pluggable interface configured to electrically mate with a corresponding rear pluggable interface on a casing of each pluggable modular device. As an example, the jbox interface chassis may include a plurality of slots or holes to receive a corresponding plurality of blades or pins on the casing of each pluggable modular device. Additionally, device adapters are described herein to convert a wide variety of legacy electrical devices into pluggable modular devices.

A composite connection socket includes a metal housing, an insulative main body, a first row conductive terminal and a second row conductive terminal. The metal housing includes an accommodating space formed therein, and the insulative main body is received inside the accommodating space. The insulative main body includes a first side plate, a second side plate and a base; the first side plate and the second side plate are arranged corresponding to each other and protrude from the base. The first row conductive terminal is arranged on the first side plate and complies with a micro USB communication protocol interface. The second row conductive terminal is arranged on the second side plate and complies with a lightning standard interface. The composite connection socket is able to commonly accommodate two cable connectors of different standards of a micro USB connector or a lightning connector inserted therein.

A connector assembly includes a first connector and a second connector, the first connector having a first contact and a mounting portion together with a projecting portion which passes through a through-hole of a connector holding plate to project on a side of a second face of the connector holding plate along a fitting direction when the first connector is mounted on a first face of the connector holding plate through the mounting portion, the second connector having a second contact and a second contact holding portion which has a first connector receiving portion extending along the fitting direction and an abutment portion formed at an end of the second contact holding portion on a side of the first connector and configured to be abutted against the second face of the connector holding plate.
