Abstract
The utility model discloses a low-power solar photovoltaic junction box, which comprises an upper cover and a lower box that are fastened with each other. Two connecting pieces are arranged inside the lower box, an anode lead-out wire and a cathode lead-out wire of a photovoltaic cell panel are connected to the lower box and respectively connected with the input ends of the two connecting pieces, cables are respectively connected with the output ends of the two connecting pieces in the eccentric positions and tightly clamped inside the lower box by fixed clamping blocks; a socket connector and a plug connector are arranged outside the lower box, the cables are led out from the lower box and respectively connected with the socket connector and the plug connector, and seal rings are respectively arranged at the lead-out sites of the cables; and a bypass diode is arranged between the two connecting pieces. The low-power solar photovoltaic junction box has simple structure, small space inside the box and low production cost, is easy to assemble, and reduces the use amount of encapsulating material of photovoltaic component manufacturers.
Description
Technical field
The utility model relates to the Application of Solar Energy field, is specifically related to a kind of small-power photovoltaic terminal box.
Background technology
Solar energy photovoltaic system is the work system of generating, transmission, (accumulate), control, (inversion) and output, and terminal box is exactly a hop wherein.
Other effect of terminal box also has: the photovoltaic panel lead-out wire be connected and fixed and to the protection of photovoltaic panel island effect.The protection of photovoltaic panel island effect realizes by bypass diode.
For the small-power terminal box, little because of its electric current, caloric value is little, so but its heat-dissipating space requires just point, so also can reduce production costs.
At present, small-power terminal box product is because the sealing and fixing size restrictions at stube cable position, cause its volume bigger, thereby make production cost higher, also make photovoltaic module manufacturer production cost improve (the embedding materials indirect cost when comprising terminal box direct cost and its assembling) indirectly.
The utility model content
The purpose of this utility model provides a kind of small-power photovoltaic terminal box, improves the easy assembling of product, reduces portion size, reduces the part materials, and the solar junction box product of a kind of easy assembling and reduction consumptive material is provided.
The technical solution of the utility model is as follows:
A kind of small-power photovoltaic terminal box, include the loam cake and the following box that are interlocked, it is characterized in that: be provided with two braces in the box under described, there are the positive and negative lead-out wires of two of photovoltaic battery panel to insert in the described boxes down and link to each other with the input of described two braces respectively, the eccentric position of described two brace outputs is connected with cable respectively, and having fixedly, fixture block is clamped on down described cable in the box; Described box down is provided with socket connector and pin connector outward, and described cable is drawn from following box respectively and linked to each other with pin connector with socket connector respectively, and the position of drawing of described cable is respectively equipped with sealing ring; Be connected with bypass diode between described two braces.
Described small-power photovoltaic terminal box is characterized in that: the input of described two braces links to each other by the mode that flexure strip is pegged graft respectively with two positive and negative lead-out wires of photovoltaic battery panel.
The beneficial effects of the utility model:
The utility model is drawn the position to cable and has been adopted the sealing ring sealing and cable has been adopted the fixed form of fixture block chucking, thereby makes its structure simpler, easily assembling, and production cost reduces; In addition, the utility model is at the eccentric position stube cable of brace output, and the space diminishes in the terminal box thereby make, and has reduced photovoltaic module manufacturer's Embedding Material consumption, thereby has reduced its production cost.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
Referring to Fig. 1, a kind of small-power photovoltaic terminal box, include the loam cake 10 and the following box 9 that are interlocked, be provided with two braces 6 in the following box 9, there are two positive and negative lead-out wires accesses of photovoltaic battery panel also to link to each other with the input of two braces 6 respectively in the box 9 down, the eccentric position of two brace 6 outputs is connected with cable 3 respectively, and having fixedly, fixture block 5 is clamped on down cable 3 in the box 9; Following box 9 outer socket connector 1 and the pin connectors 2 of being provided with, cable 3 is drawn from following box 9 respectively and is linked to each other with pin connector 2 with socket connector 1 respectively, and the position of drawing of cable 3 is respectively equipped with sealing ring 4; Be connected with bypass diode 8 between two braces 6.
The input of two braces 6 links to each other by the mode that flexure strip 7 is pegged graft respectively with two positive and negative lead-out wires of photovoltaic battery panel.
