Abstract
The invention relates to a solar photovoltaic thin-film junction box, comprising a shell (1), an external cable (3) and an end terminal connection seat (5), wherein the end terminal connection seat (5) is fixedly installed in the shell (1); a wiring hole (1.1) is formed on the front wall of the shell (1); the external cable (3) penetrates through the wiring hole (1.1) and is connected with the end terminal connection seat (5); an installation hole (1.2) is formed on the bottom wall of the shell (1); a cable fixation block (4) is arranged in the installation hole (1.2); and the cable fixation block (4) is buckled with the wiring hole (1.1) so as to fix the external cable (3). The external cable of the solar photovoltaic thin-film junction box disclosed by the invention is fixed via the cable fixation block; and when the external cable is twisted or stressed by stretching, the end terminal connection seat cannot shift or sway with the external cable, so that a diode can be efficiently prevented from loosening or breaking off from the end terminal connection seat, thus ensuring the use stability and safety of the junction box.
Description
Technical field
The present invention relates to a kind of photovoltaic film terminal box, belong to the solar film battery technical field.
Background technology
At present, human burning mass mineral obtain the energy, have caused global environmental pollution and ecological disruption, and human existence and development have been caused huge threat.And solar energy limits, need not transportation, pollution-free, the inexhaustible energy as a kind of no region, becomes most important regenerative resource in the strategy of sustainable development, begins to replace traditional fossil energy gradually and comes the service for the mankind.In the solar film battery electricity generation system, adopt photovoltaic film junction box assembly to realize the electrical connection between the solar film battery panel usually.Therefore, in the design of this miniature terminal box, main Consideration is whether to guarantee stability and the fail safe of electrical connecting unit when using in the terminal box.Existing photovoltaic film terminal box mostly adopts traditional riveting connected mode to realize being connected of line end Connection Block and external cable in the terminal box; Its connection reliability is poor; Twisted or stretched when stressed at external cable; The line end Connection Block is influenced by it also can and be shifted thereupon or rock, and very easily causes diode to get loose or break from the line end Connection Block, and is stressed when big at external cable tensile strain; Even the phenomenon that external cable and line end Connection Block break off can occur, so the stability in use of terminal box and fail safe are relatively poor.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of photovoltaic film terminal box is provided, its line end Connection Block and external cable connection reliability are good, the stability in use of terminal box and safe.
The objective of the invention is to realize like this: a kind of photovoltaic film terminal box; It comprises housing, external cable and line end Connection Block; Said line end Connection Block is fixedly installed in enclosure interior, offers wiring hole on the antetheca of said housing, and said external cable passes wiring hole and is connected with the line end Connection Block; Offer installing hole on the diapire of said housing; Said installing hole is connected with wiring hole, is provided with the cable fixed block in the said installing hole, thereby said cable fixed block and wiring hole are interlocked external cable is fixed.
The said cable fixed block left and right sides is provided with step, and said cable fixed block bottom is provided with latch.
Said wiring hole has two, is arranged in juxtaposition about said two wiring holes.
The antetheca arranged outside of said housing has tubular configured joint, and the position of said tubular configured joint is corresponding with the position of wiring hole, is set with sealing shroud on the said tubular configured joint.
Compared with prior art, the present invention has following beneficial effect:
A kind of photovoltaic film of the present invention terminal box; Its external cable is fixed through the cable fixed block; When external cable twisting or stretch when stressed, the line end Connection Block can not be shifted thereupon or rock, and can prevent effectively that diode from getting loose or breaking from the line end Connection Block; The connection reliability of external cable and line end Connection Block improves greatly, has guaranteed stability and fail safe that terminal box is used.
