Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to a protective cover of a photovoltaic connector. Background Art

[0002] Offshore photovoltaics refers to photovoltaic power stations built on the ocean. Compared to terrestrial photovoltaics, offshore photovoltaics occupy less land and generate 5%-10% more power. This is due to the open, unobstructed water surface, long hours of sunshine, and light reflected from the water. Offshore photovoltaic midstream refers to the contractors who undertake offshore photovoltaic projects. Project types are categorized as either pile-based fixed-mounted offshore photovoltaics or floating offshore photovoltaics. During the operation of offshore photovoltaics, the photovoltaic connectors in the junction boxes on the back of the modules are subject to corrosion from seawater and the surrounding ecosystem. Existing offshore photovoltaic connectors mostly use a single-layer waterproof structure, which has poor waterproof performance. Therefore, protective covers are often installed on the outside of the photovoltaic connectors to ensure safe and reliable operation in harsh marine environments.

[0003] Existing protective covers, such as a photovoltaic connector emergency protective cover disclosed in patent publication number CN117254301A, include a base, a shell and a top cover. The top of the base is provided with a receiving groove, the shell is constituted as a hood-like structure and a sealing cover is provided on the receiving groove, and the top cover is provided on the shell and is sealed and buckled with the base.

[0004] The structure of the protective cover is relatively complex, and when the photovoltaic connector is connected and transmits current, a certain amount of heat will be generated due to the existence of contact resistance. The protective cover cannot dissipate the heat in time, and the heat accumulates in the protective cover, which can easily cause the performance of the photovoltaic connector to degrade or be damaged due to excessive temperature. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the protective cover of the existing photovoltaic connector cannot dissipate heat in time, and the heat accumulates in the protective cover, which easily leads to performance degradation or damage of the photovoltaic connector due to excessive temperature.

[0006] In order to solve the above problems, the technical solution of the present invention is: a protective cover for a photovoltaic connector, comprising a bottom shell and a top cover, the middle part of the bottom shell and the top cover are provided with an arc groove, the two arc grooves together form a accommodating cavity for placing the photovoltaic connector, and wire grooves are symmetrically provided at both ends of the arc groove, the wire grooves on the bottom shell and the top cover together form a circular wire hole, a fixing ring is fixed at the top edge of the top cover, the bottom shell and the top cover are provided with annular grooves on the outside of the arc groove, a sealing ring is installed inside the annular groove, the thickness of the sealing ring is greater than the depth of the annular groove, an I-shaped installation groove is provided on the arc groove, the installation groove runs through the inner and outer surfaces of the arc groove, and a heat dissipation component is installed inside the installation groove.

[0007] Furthermore, the top cover and the fixing ring are integrally formed, and the fixing ring is movably clamped inside the bottom shell.

[0008] Furthermore, a plurality of slots are provided on the side surface of the bottom shell, and a plurality of positioning strips adapted to the slots are fixedly connected to the side surface of the fixing ring.

[0009] Furthermore, the heat dissipation assembly is fixed to the bottom shell and the top cover by insert injection molding.

[0010] Furthermore, the heat dissipation assembly includes a heat conducting plate installed on the inner side of the arc groove and a heat dissipation plate installed on the outer side of the arc groove. The heat conducting plate and the heat dissipation plate are connected and fixed by a connecting plate, and the connecting plate and the heat conducting plate are made of the same material.

[0011] The advantages of this utility model compared with the existing technology are: this utility model effectively improves the sealing of the protective cover through the double-layer sealing ring, and the protection level reaches IP68; the heat generated by the photovoltaic connector during operation is dissipated in time through the heat dissipation component, effectively preventing the performance degradation or damage of the photovoltaic connector caused by excessive temperature.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 3As shown, a protective cover for a photovoltaic connector includes a bottom shell 1 and a top cover 2. The bottom shell 1 and the top cover 2 are both provided with an arc groove in the middle, and the two arc grooves together form a accommodating cavity for placing the photovoltaic connector. Wire grooves are symmetrically provided at both ends of the arc groove. The wire grooves on the bottom shell 1 and the top cover 2 together form a circular wire hole. A fixing ring 3 is fixed at the top edge of the top cover 2. The top cover 2 and the fixing ring 3 are integrally formed, and the fixing ring 3 is movably clamped in the inside of the bottom shell 1. A plurality of card grooves are opened on the side of the bottom shell 1, and a plurality of positioning strips 5 adapted to the card grooves are fixed to the side of the fixing ring 3. The bottom shell 1 and the top cover 2 are both provided with annular grooves on the outside of the arc grooves. A sealing ring 4 is installed in the annular groove, and the thickness of the sealing ring 4 is greater than the depth of the annular groove.

[0020] Place the photovoltaic connector in the arc-shaped groove on the bottom shell 1, and place the cables at both ends in the wire groove. Place the top cover 2 on the inner side of the bottom shell 1 and press it tightly so that the positioning bar 5 is engaged in the groove, thus completing the fixation of the top cover 2 and the bottom shell 1. At this time, the two sealing rings 4 on the bottom shell 1 and the top cover 2 are squeezed against each other, and the double-layer sealing ring 4 effectively improves the sealing of the accommodating cavity, and the protection level reaches IP68.

[0021] like Figure 1 、 Figure 4 and Figure 5 As shown, an I-shaped mounting groove is provided on the arc groove, the mounting groove runs through the inner and outer surfaces of the arc groove, and a heat dissipation component is installed inside the mounting groove, and the heat dissipation component is fixed to the bottom shell 1 and the top cover 2 by insert injection molding. The heat dissipation component includes a heat conducting plate 6 installed on the inner side of the arc groove and a heat dissipation plate 7 installed on the outer side of the arc groove. The heat conducting plate 6 and the heat dissipation plate 7 are connected and fixed by a connecting plate 8, and the connecting plate 8 is made of the same material as the heat conducting plate 6.

[0022] The heat conducting plate 6 transfers the heat inside the accommodating cavity to the heat dissipating plate 7 through the connecting plate 8, and the heat is dissipated through the heat dissipating plate 7, thereby improving the heat dissipation effect of the protective cover and preventing the performance degradation or damage of the photovoltaic connector due to excessive temperature.

[0023] In specific use, the photovoltaic connector is placed in the arc groove on the bottom shell 1, and the top cover 2 is clamped and fixed on the inner side of the bottom shell 1, and the sealing of the protective cover is effectively improved by the double-layer sealing ring 4; the heat generated when the photovoltaic connector is working is absorbed by the heat conduction plate 6, and then transferred to the heat dissipation plate 7 through the connecting plate 8, and the heat is dissipated through the heat dissipation plate 7, thereby realizing timely heat dissipation and effectively preventing the performance degradation or damage of the photovoltaic connector caused by excessive temperature.
