Abstract
The utility model provides a diode connecting device of a photovoltaic junction box. The contact resistance between the diode and a connecting plate is reduced, the conversion rate of photovoltaic cells is improved, the connection between the diode and the connecting plate is stable, oxidation of the diode and the connecting plate is effectively prevented, loosening between the diode and the connecting plate is prevented, and the connecting reliability is improved. The diode connecting device comprises a base, wherein connecting plates are arranged at both ends of the base. The diode connecting device is characterized in that the diode is fixed on the connecting plates through welding.
Description
Technical field
The utility model relates to the technical field of photovoltaic apparatus, is specially a kind of diode jockey of photovoltaic junction box.
Background technology
In the photovoltaic industry, solar panel connects between the user, needs to adopt photovoltaic junction box; Adopt diode to connect solar panel and subscribers feeder in the photovoltaic junction box, see Fig. 1, see Fig. 1; In the photovoltaic junction box, what the diode jockey adopted is plug-type connected mode, inserts brace 2-1,2-2 and the installing hole 4-1, the 4-2 that are arranged on adjacent pans 1-1,1-2 to diode 3 two ends respectively and forms in the diode slot; After perhaps being fixed on diode on the fin, diode inserts in brace 2-1,2-2 and installing hole 4-1, the 4-2 formation diode slot through fin then, forms conduction path; Existing diode installing and connecting apparatus is on base, to go out installing hole 4-1,4-2, and brace 2-1,2-2 insert among installing hole 4-1, the 4-2 and form the diode slot with installing hole 4-1,4-2 then, form conduction path; Because the material that the fin in the existing photovoltaic junction box adopts usually is a brass; And brace is a red copper, and the electric conductivity of brass and red copper is different, and its contact resistance is big; Influence the transfer ratio of photovoltaic cell; Because be directly or through fin to peg graft indirectly between diode and the brace, the time has been grown oxidation easily between diode or fin and the brace, causes becoming flexible between diode or fin and the brace; Make loose contact between diode or fin and the brace, the poor reliability of its connection.
Summary of the invention
To the problems referred to above; The utility model provides a kind of diode jockey of photovoltaic junction box, makes the contact resistance of diode and brace little, has improved the transfer ratio of photovoltaic cell; And make diode stable with being connected of brace; Prevent the oxidation between diode and the brace effectively, prevented becoming flexible between diode and the brace, improved the reliability of its connection.
Its technical scheme is such, a kind of diode jockey of photovoltaic junction box, and it comprises base, said base two ends are provided with brace, it is characterized in that: diode is fixed by welding on the said brace.
It is further characterized in that: corresponding brace is that the protruding bending that is provided with on the said base forms on the said base; Said brace is provided with U-lag, and said diode is weldingly fixed in the said U-lag; Said base two ends are respectively arranged with two braces.
In the said structure of the utility model; Because diode is fixed by welding on the brace on the base, make diode stable with being connected of brace, prevented the oxidation between diode and the brace effectively; Prevent becoming flexible between diode and the brace; Improved the reliability of its connection, and the contact resistance of diode and brace is little, has improved the transfer ratio of photovoltaic cell.

Fig. 2 is the diode jockey master TV structure sketch map of the utility model photovoltaic junction box;
Fig. 3 is the structural representation of looking up of Fig. 2;
Fig. 4 is the diode sketch map.
Embodiment
See the diode jockey of Fig. 2, Fig. 3, Fig. 4, a kind of photovoltaic junction box; It comprises base 1; Base 1 is provided with two the brace 2-1, the 2-2 that are formed by protruding bending; Brace 2-1,2-2 are provided with U-lag 3-1,3-2, and diode 4-1,4-2 two ends are fixed by welding in respectively in brace 2-1,2-3 and 2-2,2-4 on the adjacent pans last U-lag 3-1,3-2 and 3-3, the 3-4.
Because the diode two ends are through being welded to connect on the brace on the base; Make diode stable with being connected of brace; Prevent the oxidation between diode and the brace effectively, prevented becoming flexible between diode and the brace, improved the reliability of its connection; And the contact resistance of diode and brace is little, has improved the transfer ratio of photovoltaic cell.
Brace is that the protruding bending that is provided with on the base forms; Base and brace are one-body molded; Prevent the loose shift of brace, made that the connection of the interior diode of photovoltaic junction box is stable, guaranteed the quality of connection of diode; U-lag is placed on the brace diode more simply, easily, and diode and brace are welded to connect.
It is for diode is connected with adjacent brace successively that the base both sides are respectively arranged with two braces, and the base both sides can be provided with a brace or a plurality of braces certainly.
In the present embodiment; The purpose of U-lag is for diode is securely fixed on the brace more, if brace does not adopt the U-lag inner structure certainly, diode is fixedly welded on the brace; The connection that also can effectively prevent diode is loosening; The contact resistance that reduces diode and brace is little, has improved the transfer ratio of photovoltaic cell, also is the protection range of the utility model.
Claims (4)
