Abstract
The utility model discloses a conjunction box of a photovoltaic cell. The conjunction box comprises a box body and a box cover, wherein conducting strips are installed in the box body, diodes in gaps between the conducting strips respectively connect the conducting strips, and the box body is covered by the box cover. The conjunction box also comprises an embedded piece which is installed in the box body and positioned under the conducting strips, wherein the embedded piece includes a groove which can be cooperated with the conducting strips in installation. The conducting strips are molded via once stamping and form an integral body. The conjunction box further comprises a bus bar which is fixed on the conducting strips through spot welding. Cable through holes are respectively formed in the left and right sides outside the box body, and an ultrasonic sheet is positioned in each cable through hole and cooperated with the through hole. The embedded piece is processed by heatproof material and is mainly used for supporting the conducting strips. The conducting strips are molded via once stamping, thereby simplifying manufacturing and assembly process. The ultrasonic sheets employ the ultrasonic bonding technology, thereby saving the cost and improving the product stability compared with fixing nuts in the cables.
Description
Technical field
The utility model belongs to the part field of solar-energy photo-voltaic cell, relates in particular to a kind of photovoltaic cell junction box.
Background technology
Diode and metallic conduction sheet are the critical components of photovoltaic cell junction box.At present the operating procedure of terminal box is first connection box set to be installed completely, then metallic conduction sheet is put into after terminal box, then welding diode on metallic conduction sheet.Adopt the shortcoming of such operating procedure to be: operation easier and the efficiency of in terminal box, metallic conduction sheet and diode being welded are lower.
Summary of the invention
The purpose of this utility model is to provide a kind of photovoltaic cell junction box, thereby reduces the assembling difficulty of terminal box, improves the welding quality of metallic conduction sheet and diode.
For this reason, the technical solution adopted in the utility model is such: a kind of photovoltaic cell junction box, comprise box body and lid, and conducting strip is housed in box body, between conducting strip gap, there is diode to be connected, by lid, bound; It is characterized in that: it also comprises an embedded component, described embedded component is arranged in box body and is positioned under conducting strip, on described embedded component, has groove, and described groove can coordinate and install with conducting strip; Described conducting strip is one time punching molded, is an integral body; It also comprises busbar, and described busbar is fixed on conducting strip by spot welding; The right outside side of box portion left has respectively a cable through hole, and each cable through hole has one ultrasonic, and described ultrasonic is matched with through hole.
Further, described embedded component adopts exotic material; Conducting strip adopts wicking processing or conducting strip full wafer to adopt zinc-plated processing in spot welding place; Described ultrasonic adopts ultrasonic welding process to be welded on cable through hole.
Further, described box body outside has two clamps, has respectively a wire fixing clamp on each clamp, and wire fixing clamp is fixed on box body outside by clamp buckle.
Further, between described box body and lid, adopt casting glue form to seal.
The beneficial effect of the technical program: embedded component is to process with exotic material is mainly for supporting conducting strip.And conducting strip is one time punching molded, manufacture and assembly technology have been simplified.Ultrasonic technique that adopts ultrasonic bonding, compares that cable place nut is fixing had both saved cost, has improved again the stability of product.Terminal box adopts casting glue form in water proofing property, has both played the good thermolysis of inside configuration, has simplified again structure, and profile is smaller and more exquisite before comparing.Busbar adopts spot welding form, and it is zinc-plated that conducting strip spot welding place adopts wicking processing or conducting strip full wafer to adopt, and is all in order to improve the reliability of spot welding.
