PHOTOGALVANIC INSTALLATION ELECTRICAL CONNECTION DEVICE Russian patent published in 2019 - IPC H02S40/34 H02S40/36 E04D13/18 

FIELD: construction.

SUBSTANCE: group of inventions relates to an external skin panel of a building and an electrical junction box for it. Building outer skin panel comprises: an upper transverse edge comprising an upper overlapping area for overlapping by an adjacent panel; a lower transverse edge comprising a lower overlapping area for overlapping the adjacent panel; central part connecting transverse edges and closed by at least one photovoltaic module comprising electric pole on one of its longitudinal ends and electric pole of reverse polarity at other end; passage located in the lower overlapping area, through which passes an electric wire connecting one of two electric poles of the photovoltaic module to the electrical connector located on the back side of the panel in the lower overlapping area; an opening in the upper overlapping area, in which an electrical junction box is installed, connected to the other electric pole of the photovoltaic module by means of an electric wire. Junction box comprises: bottom; a sidewall surrounding the bottom extending perpendicular thereto, having on its outer side a peripheral flange configured to hold the junction box in place in the opening; wire output located in the junction box portion located above the peripheral flange and configured to connect the electrical junction box to the other electrical terminal of the photovoltaic module; an inner cavity confined by a bottom and a wall, having an electrical terminal with an axis perpendicular to the bottom, configured to connect an electrical connector located on the back side of the adjacent outer skin panel; detachable electric switch connecting electric terminal with wire output and located on side wall of junction box.

EFFECT: easier assembling of panels and connection by wires of photovoltaic modules.
