Abstract: A solderable electric connector formed of a metal sheet as a single body includes a flat bottom portion soldered to a conductive pattern of a printed circuit board (PCB), an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof, and a housing vertically bent and extended from one end of the bottom portion in a width direction and surrounding the elastic fastening portion. Herein, a front end of the housing is vertically bent downwards and forms a supporting plate and a penetration hole is formed in a certain location on the supporting plate. Also, a pressurizing projection projects from a top surface of the elastic fastening portion and a metal core of a wire passing through the penetration hole is pressurized between the pressurizing projection and a bottom surface of the housing and coupled therewith.

Abstract: A solderable electric connector formed of a metal sheet as a single body includes a flat bottom portion soldered to a conductive pattern of a printed circuit board (PCB), an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof, and a first housing vertically bent and extended from one end of the bottom portion in a width direction and surrounding the elastic fastening portion. Herein, a front end of the first housing is vertically bent downwards and forms a supporting plate and a penetration hole is formed in a certain location on the supporting plate. Also, a pressurizing projection projects from a top surface of the elastic fastening portion and a metal core of a wire passing through the penetration hole is pressurized between the pressurizing projection and a bottom surface of the first housing and coupled therewith.

Abstract: Disclosed is a junction box which includes voltage and current sensors that are connected to both ends of bypass diodes provided within the junction box to sense currents and voltages of the solar cell module; a MPPT controller that tracks a maximum power point from current and voltage values sensed from the voltage and current sensors; and a voltage controller that includes a switch for controlling an operation of the solar cell module, and controls a voltage corresponding to the tracked maximum power point to be output.

Abstract: The present invention relates to a smart junction box for a solar cell module, and provides a smart junction box for a solar cell module which enables an operator to easily connect and separate ribbon cables using the operation of the levers of pressing units, thereby being able to improve the contact stability of ribbon cables, and which has a heat sink structure, thereby effectively emitting the heat generated by the ribbon cables and the diodes to the outside. For this purpose, the smart junction box for a solar cell module of the present invention includes bus bars for transmitting electricity flowing from ribbon cables; and pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars depending on whether both ends of the lever projected by the manipulation of an operator are inserted into recesses formed in a body.
