An inverter (1) for a grounded direct voltage source, in particular for a photovoltaic generator (2), a battery or a fuel cell, for converting the direct voltage into an alternative voltage with a DC-DC converter (3) and a pulse inverter that is supplied by said DC-DC converter (3), said DC-DC converter (3) being configured to be an oscillating circuit inverter and comprising a series resonant oscillating circuit, said DC-DC converter (3), which is configured to be an oscillating circuit inverter, being configured to be a series-compensated oscillating circuit inverter with a choke (L1) and a series-mounted capacitor array consisting of two or several oscillating circuit capacitors, a rectifier bridge branch including 2 diodes (D3, D4; D5, D6, . . . ), being connected to each of the partial oscillating circuit capacitors, said rectifier bridge branch being connected with its positive or its negative pole to output side intermediate circuit capacitors which are preferably connected in series so that said DC-DC converter (3) delivers at least two bipolar output voltages and is combined with the pulse inverter (4) with a divided voltage intermediate circuit that is supplied from the oscillating circuit inverter.

The embodiment of the invention relates to the field of connection structures and terminals, in particular to a FPC connection structure and a terminal. Thus, through simple structure connection, grounding of a flexible printed circuit FPC is achieved and grounding of an acoustic device is achieved. In the embodiment of the invention, the FPC connection structure comprises a first contact and a second contact. The first contact is connected with a spring sheet which is conducted with a grounding wire on a main board FCB. The second contact is connected with the acoustic device. The first contact and the second contact are arranged on the FPC which is used for conducting the first contact and the second contact. According to the invention, the first contact is connected with the spring sheet of the grounding wire, and the second contact is connected with the first contact and the acoustic device, so through the simple structure connection, grounding of the flexible printed circuit FPC is achieved and grounding of the acoustic device is also achieved.

The invention brings forward a solar energy support guide rail, a clamp block, an intermediate-voltage block, and a side-voltage block in cooperative usage. The guide rail comprises a main body; and a first groove-shaped track is arranged at the top of the main body, a nut track is arranged at one side wall of the main body, and a second groove-shaped track is arranged at the other side wall of the main body. The opening direction of the first groove-shaped track is arranged upwardly; the opening direction of the second groove-shaped track is perpendicular to the opening direction of the first groove-shaped track and is against the main body; the opening direction of the nut track is perpendicular to the opening direction of the first groove-shaped track and is against the main body; and the opening direction of the second groove-shaped track is opposite to the opening direction of the nut track. The solar energy support guide rail can be installed in an outer hexagonal mode or by means of the clamp block; and because of the diversified installation ways, requirements under different backgrounds can be met.

The invention discloses a novel integrated combined electrical appliance. The novel integrated combined electrical appliance comprises a three-station disconnecting switch, a vacuum breaker or a load switch or a load switch-fuse combined electrical appliance which is matched with the three-station disconnecting switch, and an operating mechanism, wherein the three-station disconnecting switch is arranged on the upper side of the integrated combined electrical appliance and distributed in the sequence of front, middle and back; other electrical elements are embedded into epoxy embedded poles and arranged below the disconnecting switch; the epoxy embedded poles are spliced together to form a partition plate so as to separate a bus room from a switching cable room; in addition, the upper outgoing lines of the other electrical elements form the disconnecting link rotating pivots of the three-station disconnecting switch; the operating mechanism is a novel difunctional spring operating mechanism and is arranged at the front end of the integrated combined electrical appliance; a torsional spring energy storage mechanism at the upper end of the operating mechanism drives the rotating shafts of the three-station disconnecting switch to act so as to open and close; and a spring winding energy storage mechanism at the lower end of the operating mechanism drives the other electrical elements to operate. Current sensor installing rooms and line slots are reserved at the lower ends of the epoxy embedded poles, so that the novel integrated combined electrical appliance has a compact structure and is safe in use, room and fault sources are reduced, and cost is lowered.
