Abstract
The utility model discloses a combined type photovoltaic conjunction box. The conjunction box is composed of an anode box and a cathode box, and a connecting box is arranged between the anode box and the cathode box. Taking the anode box as an example, the anode box comprises a bottom base and a cover plate, and the bottom base and the cover plate are in buckling connection; the anode box also comprises a bottom plate, and a first conducting strip and a second conducting strip are arranged on the bottom plate; the anode box further comprises a diode fixed between the two conducting strips; the bottom plate and components arranged on the bottom plate are fixed on the bottom base by reflow soldering; and a cable interface is arranged on the side wall of the bottom base of the anode box, and an angle ranges from 20 degrees to 45 degrees is formed between a center axis of the cable interface and a horizontal axis of the bottom base of the anode box. Each cable interface of the conjunction box is inclined by a certain angle, by employing such a manner in bonding components and the conjunction box, a phenomenon that the components and the conjunction box are infirmly bonded due to the interference between a cable and component frames when a conjunction box of the same kind is horizontally led out, the cable cannot be excessively fold when being connected with the components, so that the service lifetime of the cable is prolonged.
Description
Technical field
The utility model belongs to the solar battery connecting box field, especially relates to a kind of composite type photovoltaic junction box.
Background technology
Along with the application of solar power generation is more and more general, with the closely-related terminal box of its application, also constantly weed out the old and bring forth the new, many groups solar module that solar power generation adopts matrix form to arrange becomes electric energy by sunlight conversion, each group solar module is connected with photovoltaic cell junction box, and terminal box is connected with the other parts of solar power system again.
At present, battery connecting box has been a kind of comparatively ripe product, generally comprises box body, lid, and sheet metal is housed in box body, with diode, is connected between sheet metal; Box side wall is provided with cable interface, in box body, also is provided with the busbar jockey.In terminal box, the cable interface of terminal box sidewall is generally horizontal outlet, but during the horizontal outlet of terminal box, because cable and module frame are interfered the poor attachment phenomenon caused, can cause the operational failure of terminal box integral body, when assembly connected simultaneously, cable can the transition bending.On the other hand, need specific parts at fixed-conductive film, this can increase the volume of terminal box, and can reduce to a certain extent the production efficiency of terminal box.
Summary of the invention
In order to address the above problem, the utility model provides a kind of composite type photovoltaic junction box, thereby reaches improvement purpose.
Adopt following technical scheme for this reason, the composite type photovoltaic junction box, by anodal box and negative pole box, formed, between anodal box and negative pole box, has connecting box, described anodal box and negative pole box structure are Mirror Symmetry, the anodal box of take is example, it comprises base and cover plate, both are fastened and connected mutually, anodal box also comprises a base plate, the first conducting strip and the second conducting strip are installed on described base plate, it also comprises a diode, described diode is fixed between two conducting strips, and by reflow soldering, the parts on base plate and base plate are fixed on base, it is characterized in that: also have a cable interface on described anodal box base sidewall, the central shaft of described cable interface and the trunnion axis of anodal box base have the angle of 20-45 °.
Further technical scheme, what described anodal box plate adopted is exotic material; Described diode is fixed between two conducting strips by selecting the tin cream subsides.
By such technical scheme, the cable interface of terminal box has the inclination of certain angle, this mode is in the bonding terminal box of assembly, in the time of can avoiding the horizontal outlet of similar terminal box because cable and module frame are interfered the poor attachment phenomenon caused, when simultaneously assembly connected, cable can the transition bending, effectively guarantee effective work of cable, improved cable useful life.In addition, this terminal box is not specifically designed to the instrument of location conducting strip, can reduce small product size, has saved a large amount of man-hours, has improved simultaneously Product Precision.
