A photovoltaic array () for generating DC power by receiving sunlight is installed in a balcony () of the individual unit, the DC power is converted by an inverter () into AC power, and the AC power output from the inverter () is supplied to the plurality of electrical loads in a distributed manner by a distribution board () of the individual unit. On the other hand, a magnitude of DC power generated by the photovoltaic array or a lithium-ion battery and a magnitude of electrical power consumed by the electrical loads are compared by an electrical power comparator. Depending on the comparison result, an electrical power switch may supply the DC power via the inverter to the electrical loads or a low-voltage system, or may supply electrical power from the low-voltage system to the electrical loads or the lithium-ion battery.

Connecting structure of coaxial cable and coaxial connector

A coaxial connector with a switch can be used even when an internal ANT and an RF circuit on a printed wiring board are inversely arranged by mounting the connector through the reverse mounting. The connector is mounted on a printed wiring board by engaging a notch portion in an edge thereof and comprises a normally closed terminal, a common terminal, an insulator, a shell, and a housing. A pair of connecting portions of the shell are horizontally symmetric with respect to a vertical plane passing the center or nearly the center of the housing. The connecting portions of the normally closed terminal and the common terminal are also horizontally symmetric with respect to the vertical plane. A top surface and a bottom surface of each of the connecting portions are vertically symmetric with respect to a horizontal plane passing the centers or nearly the centers of the connecting portions.

Coaxial connector with switch

A coaxial cable connector plug includes a connector body having the end of a coaxial cable fixed therein and a housing having an insertion hole to accommodate the connector body. The housing has a cantilever-like engagement nail extending in the insertion hole, thereby permitting the connector body to be caught by a frusto-conical transition in the insertion hole. The housing has a catch hole made in the vicinity of the cable-inlet of the housing. When a wedge-like retainer is inserted into the remaining space between the connector body and the floor of the housing, the wedge-like retainer is caught by the hook end, thus filling the remaining space and making the coaxial cable tightly retained in the housing. With this arrangement, the connector body can be removed from the housing so as to be reused.

Coaxial connector

A connector receptacle has an outer conductor inserted in its housing, the outer conductor having an insulator inserted in its inner space, and the insulator having a terminal piece embedded therein for connecting with a counter part. The housing has a longitudinal slot made therein, and the outer conductor includes a split conductor body having two opposite flap projections formed on its joint edges. The conductor body is inserted in the housing with the opposite flap projections press-fitted in the slot. This arrangement assures that complete shielding is provided and that the receptacle parts are tightly assembled.

Electric connector

A resilient, curved switch terminal is elastically flexed when deflected by a connector pin inserted into a coaxial connector. The switch terminal is sufficiently long to provide a broad range of resiliency that accommodates plug pins of various dimensional tolerances. The switch terminal contacts a fixed terminal in a normally closed contact position. A connector pin in a mating connector opens the normally closed contact while making a new contact through the connector pin. The terminals are long enough to prevent solder flux from flowing to contacting portions. Solder flux residue is avoided on contacting portions and a more reliable contact is obtained. The portion of the switch terminal that contacts the plug pin is slanted to prevent accumulation of any contaminants such as dust or plating residue that enters the coaxial connector. The slanted contact portion also facilitates assembly of the coaxial connector switch. The resulting coaxial connector is easier to manufacture and has greater reliability while presenting a thin and compact aspect.

A lock mechanism by which a mating connector socket to be mounted on a printed wiring board of an electronic equipment can be formed into a small size, and even if the direction of mounting of the connector socket is inverted, or if the electronic equipment itself is turned upside down, the locking can be easily released. In a connector plug (10) for electrically connecting a mating connector socket (20), mounted on a printed wiring board of an electronic equipment, to another electronic equipment through an electric cable (30), when the connector plug (10) is fitted in the connector socket (20), this fitted condition is locked by a lock mechanism, and the lock mechanism of the connector plug includes retractable lock pawls (12) provided at a face side of a fitting portion (11) of a generally rectangular parallelepiped shape, and lock release buttons (14) provided respectively at opposite side surfaces of a finger grip portion (13).

Connector plug-locking mechanism

A coaxial connector with a switch has a central terminal, an outer terminal, and a switch terminal. When a plug is inserted in the coaxial connector, the central terminal is connected to the plug central terminal of the plug, while the outer terminal is connected with the plug outer terminal. At this time, the switch terminal comes into contact with the plug outer terminal, and it is electrically connected to the outer terminal via the plug outer terminal. The outer terminal is shaped as a cylindrical shell, and the switch terminal is positioned so as to face the outer terminal. When the plug is inserted, the plug outer terminal is inserted between the outer terminal and the switch terminal, whereby the switch terminal is electrically connected to the outer terminal, and the switch is activated. When the plug is not inserted, the switch terminal is separated from the outer terminal and, accordingly, the switch is not activated.
