(ES1072216-U)   NOVELTY - The box (1) has an electronic device or printed circuit board (PCB) embedded inside a housing base (2). Connection cables (5) are pressed through a ring. The connection cables are connected to interior of the box through a flange and fastening screws. A cap (4) is provided with a central depression (21), which is connected to the housing base by fixing screws (14) in holes of the base. Walls are formed around outer side fins (6). Two circular holes (7) are formed in a wider front part of the box. The connection cables are inserted into the circular holes.    USE - Junction box for use on back of a photovoltaic solar module.    ADVANTAGE - The box provides reliable electrical connection, and prevents electronic components and electrical connections of photovoltaic solar module from being damaged due to impact, vibration or fatigue. The box enhances durability and reliability of the photovoltaic solar module. The box increases dissipation of heat. The box has better chemical stability and optimum dielectric properties. The box is resistant to UV radiation and flame resistant.    DETAILED DESCRIPTION - A connector box for solar photovoltaic modules, that being especially conceived for assembly to the rear area of a solar photovoltaic module, and being of the type that is made up from a base housing (2) that includes cooling fins for the dissipation of the heat, on the inside of which there is a clamp for the holding of the input cables of the connector box, having a protector lid that is appropriately sealed, in such a way that parts that make up the box itself are manufactured from plastic materials that have high resistance to adverse weather conditions, likewise chemical products, the materials being provided with additives that provide resistance to ultra-violet radiation. There is the additional incorporation of means of heat dissipation, brought about in an electronic device or printed circuit board (PCB) (9) embedded on the inside of the base housing (2) by pressure, that provides the electrical connection through the connectors or connector cables (5) faced outwards so as to be connected to an external connection.
