The mode that junction box structure of the prior art adopts multiple working of plastics to assemble, such as, Authorization Notice No. CN 203708192U, a kind of photovoltaic junction box described in invention in authorized announcement date on July 9th, 2014, include box body, be provided with diode modules and wiring board in box body, described cartridge outer surface is inlaid with radiator, the diode modules being positioned at box body is attached at the radiator back side, and is electrically connected with the copper conductor on wiring board.Adopt the terminal box of multiple working of plastics assembling mode, produce problems in an assembling process: install loaded down with trivial details, assemble not in place.In use also may produce box body cracking, the problems such as sealing difference.
For above-mentioned technical problem, application number 201010505274.8, the patent application in September 28 2010 applying date provides a kind of Integral injection molded junction box and manufacture method thereof, described Integral injection molded junction box comprises: lid, box body, diode, conducting strip and cable, welding diode on conducting strip, and is bundled together with the mode of conducting strip plastic-injection; Cable is connected to the binding post place of conducting strip, and with the conducting strip be bundled together and diode again use the mode of plastic-injection and box body one-body molded, and to be formed in box body.Although foregoing invention application saves the installation labour cost of terminal box, but, in actual applications, because terminal box will bear higher temperature, the phenomenon of layering may be there is in the plastic cement that quadric injection mould is formed, cause that the intensity of terminal box reduces, malformation, sealing decline.
Summary of the invention
Technical problem solved by the invention: the terminal box adopting secondary injection molding, due to the more difficult control of injecting condition, terminal box not easily fuses into one, in use, under the effect of high temperature, the two-layer plastic cement of terminal box may layering, so by causing that the intensity of terminal box reduces, malformation, sealing decline.
The invention provides following technical scheme: a kind of terminal box of direct injection mo(u)lding, comprise diode, electric conductor, cable, box body, lid, described diode is arranged on electric conductor, described cable is connected with electric conductor, the structure of described box body is single injection-molded, described box body is provided with connection chamber, and the junction of described box body parcel electric conductor and cable, described diode is positioned at connection chamber.
By technique scheme, diode, electric conductor, cable are integrally imbedded in bed die after connecting, after matched moulds, single injection-molded box body, box body forms connection chamber, the junction of electric conductor and cable is wrapped in box body, and the free end of cable gives prominence to box body, and diode and partially conductive body are positioned at connection chamber.Busbar is inserted in described connection chamber, then encapsulating, afterwards, lid buckle closure, on described connection chamber, forms complete photovoltaic junction box.By technical solutions according to the invention, the junction box body technical problem that in use easy to crack, sealing is poor can be solved; It also avoid through the shaping terminal box of Multi-step injection molding in use, may there is the risk of layering in terminal box under high temperature action.The terminal box of direct injection mo(u)lding of the present invention, not only simplify the production process of terminal box, improve production efficiency, thoroughly solve the assembling of usual loose mail and the uniform security risk problem brought, and improve the degree of protection of terminal box, and ensure that the long-term effectiveness of degree of protection.
As a further improvement on the present invention, described electric conductor is structure as a whole.Diode connects the two ends of electric conductor, and so, diode still can play the effect of protection solar module.As further improvement, described electric conductor is provided with protuberance, and described protuberance offers draw-in groove, and described diode two ends are provided with connecting portion, and described connecting portion is closely connected in draw-in groove.Design like this, both ensure that the connection between diode and electric conductor, eliminated again the trouble that prior art adopts welding manner, was conducive to simplifying procedure of processing, cost-saving.As further improvement, described electric conductor is provided with outstanding both ends, and described cable is connected with electric conductor by both ends.
As a further improvement on the present invention, the edge of described connection chamber is provided with outstanding buckle, and the edge of described lid has draw-in groove, and described outstanding buckle is fastened in draw-in groove.
