Abstract
A lid for a junction box includes a structure which is arranged to connect and seal an opening of the junction box. The sealing prevents the ingress of foreign matter such as liquids or solid particles into the junction box. The structure is, or includes, a window that is transparent to visible light to enable visual inspection inside the junction box. The lid includes a cover that is opaque to UV or UV-IR wavelengths and is arranged to selectively: (a) shield the transparent portion of the structure from direct impingement of a wavelength or a band of wavelengths to prevent transmission of the wavelength or a band of wavelengths into the junction box; and (b) enable visual inspection inside of the junction box through the transparent portion.
Claims11
A junction box for use in an outside exposed environment comprising:
- a plurality of walls defining a cavity and an opening, the plurality of walls being opaque to at least UV radiation;
- a structure arranged to mechanically connect to one or more of the walls to close and seal the opening and the cavity, at least a portion of the structure being transparent to visible light to enable visual inspection inside the junction box;
- a cover for the at least a portion of the structure being transparent to visible light, the cover being opaque to at least UV electromagnetic radiation and arranged to be movable between a closed position where the cover overlies the at least a portion of the structure to prevent transmission of UV radiation into the junction box and an opened position where the cover is displaced from the at least a portion of the structure to enable visual inspection inside of the junction box;
- and
- a pivot coupling that couples the cover to the structure, the pivot coupling being located vertically above a centre of gravity of the cover wherein the cover is at least gravity biased toward the closed position.
