Abstract
The utility model discloses a junction box for a solar battery module. The junction box comprises an upper lid (1), a casing (2), a diode (6), a cable (7) and a wiring module arranged in the casing (2), as well as an outer bracket (5) and an inner bracket (4), and is characterized in that the cable (7) is directly connected with the casing (2) after being punched by a wire fastener (8), the diode (6) is in pin plug-in connection with the inner bracket (4) in a soldering manner, a dimensional trough-type empty-out structure is arranged below the casing (2), and a radiator (3) is embedded into the empty-out structure.
Description
Technical field
The utility model relates to a kind of terminal box that is used for electro-optical package, this terminal box is installed on the back side of electro-optical package and in inside and has wiring element, described wiring element is as the conductor of plate side and being connected of supply lines that will energising, the electricity that will produce by solar panels by means of the described supply lines electric supply installation in the electrical network that lead.
Background technology
At present, the terminal box that is used for solar module of prior art has the following disadvantages: 1. binding post and Wiring module adopt and peg graft or the screw fixed form, are easy to generate loosening in the use.2. contacting of the copper sheet in bypass diode and the plug connector is some contact, wobble effects terminal box function of use in Product transport and the use.3. temperature is higher in the box body during diode operation can not effectively dispel the heat to the outside.Therefore, the technical staff thirsts for this is improved.
The utility model content
For overcoming the deficiencies in the prior art, provide a kind of terminal box that is used for solar module of architecture advances.
For achieving the above object, the utility model is realized by following technical solution:
A kind of terminal box that is used for solar module comprises loam cake 1, housing 2, diode 6, cable 7, is arranged at Wiring module and support arm 5 and inner support 4 in the housing 2; Cable 7 by Line pressing buckle 8 punching presses after directly and housing 2 link together.Described diode 6 adopts pin to peg graft and the scolding tin welding manner is connected on the inner support 4.Adopt the three-dimensional grooved structure of soaring below the described housing 2, be inlaid with radiator 3 at this structure place of soaring.
Compared with prior art, the beneficial effects of the utility model are: the conducting better effects if, radiating effect is obvious, product strength is high, characteristics simple in structure, reasonable in design, loading, unloading convenient.
Description of drawings
For ease of understanding the utility model, the spy is further instruction in addition in conjunction with the accompanying drawings:
Fig. 1 is the internal structure schematic diagram that the utility model adopts cable to be connected with the inner conductor punching press;
Fig. 2 is that the utility model adopts pin to peg graft and scolding tin Welding Structure schematic diagram;
Fig. 3 is that the utility model adopts edge heat spreader structures schematic diagram;
Fig. 4 is the utility model superstructure schematic diagram.
Embodiment
For the ease of understanding the utility model, the spy is further described in conjunction with embodiment, but present embodiment should not regarded as any restriction of the present utility model.
In conjunction with each accompanying drawing, a kind of terminal box that is used for solar module comprises loam cake 1, housing 2, diode 6, cable 7, is arranged at Wiring module and support arm 5 and inner support 4 in the housing 2; Cable 7 by Line pressing buckle 8 punching presses after directly and housing 2 link together.Described diode 6 adopts pin to peg graft and the scolding tin welding manner is connected on the inner support 4.Adopt the three-dimensional grooved structure of soaring below the described housing 2, be inlaid with radiator 3 at this structure place of soaring.
When installing and using, radiator 3 connects together with housing 2 bottoms by injection moulding; Cable 7 connects together with support arm 5 by punching press; Then support arm 5, inner support 4 are installed to the relevant position of housing 2; Then diode 6 is inserted in support arm 5 and inner support 4 draw-in grooves by cathode and anode directions; Weld the pin of diode 6 again with scolding tin; Again by ultrasonic bonding Line pressing buckle 8; Then loam cake is incorporated on the housing 2; Promptly finish the assembling of terminal box.
When mounted:
1. cable directly and the punching press of terminal box inner conductor link together.Thereby avoided traditional socket connection mode to bring loose contact to cause the too high damage of conductor local temperature bypass diode.Punching press connects can increase cable and the terminal box intensity that is connected firmly again.
2. the connection of diode adopts pin to peg graft and the scolding tin welding manner., avoided because of the vibrations in the handling process, or installed and used in the process, and made bypass diode the situation of loose contact occur, improved the functional reliability of this terminal box, increased contact area simultaneously, promote electric conductivity and heat transfer property.
3. the terminal box base is inlayed radiator; radiator and box body bottom are injection molded into one; being designed to the trip form on the radiator simultaneously prevents under the radiator high-temperature condition bad in conjunction with effect; on the basis of existing photovoltaic terminal box, set up radiator; so that in time reduce the temperature of box internal heat generation device; prolonged the useful life of terminal box, more effective protection solar panel.
Claims (3)
1. a terminal box that is used for solar module comprises loam cake (1), housing (2), diode (6), cable (7), is arranged at Wiring module and support arm (5) and inner support (4) in the housing (2); It is characterized in that: cable (7) by Line pressing buckle (8) punching press after directly and housing (2) link together.
2. the terminal box that is used for solar module according to claim 1 is characterized in that: described diode (6) adopts pin to peg graft and the scolding tin welding manner is connected on the inner support (4).
3. the terminal box that is used for solar module according to claim 1 and 2 is characterized in that: adopt the three-dimensional grooved structure of soaring below the described housing (2), be inlaid with radiator (3) at this structure place of soaring.
