Abstract
The invention provides a diode connection device for a photovoltaic wiring box. According to the diode connection device, the contact resistance of a diode and a connection sheet is small, the conversion efficiency of a photovoltaic battery is improved, and the connection between the diode and the connection sheet is stable. Therefore, the oxidation between the diode and the connection sheet can be effectively prevented; the release between the diode and the connection sheet can be prevented; and the connection reliability is improved. The diode connection device comprises a base. Connection sheets are arranged at the both ends of the base. The diode connection device is characterized in that a diode is fixed on the connection sheets by welding.
Description
Technical field
The present invention relates to the technical field of photovoltaic apparatus, be 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 invention provides a kind of diode jockey of photovoltaic junction box, make the contact resistance of diode and brace little, 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 present invention; 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.
Description of drawings
The diode jockey structural representation of the existing photovoltaic junction box of Fig. 1;
Fig. 2 is the diode jockey master TV structure sketch map of photovoltaic junction box of the present invention;
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 protection scope of the present invention.
Claims (4)
