Technical field
The present invention relates to a kind of photovoltaic film terminal box, belong to solar film battery technical field.
Background technology
At present, mankind's mineral that burn in a large number obtain the energy, have caused global environmental pollution and ecological disruption, and the mankind's survival and development have been caused to huge threat.And solar energy as one without regional limits, without transport, pollution-free, the inexhaustible energy, become most important regenerative resource in the strategy of sustainable development, gradually start to replace traditional fossil energy and come for mankind service.In solar film battery electricity generation system, conventionally adopt photovoltaic film junction box assembly to realize the electrical connection between solar film battery panel.Therefore,, in the design of this miniature terminal box, main Consideration is whether can to guarantee stability and the fail safe in the time of application of electrical connecting unit in 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 terminal box, its connection reliability is poor, twisted or stretched when stressed at external cable, line end Connection Block also can be subject to it affect and be shifted thereupon or rock, very easily cause diode to get loose or break from line end Connection Block, stressed when larger at external cable tensile strain, the phenomenon that even there will be external cable and line end Connection Block to disconnect, therefore the stability in use of terminal box and fail safe are poor.
Summary of the invention
The object 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 object of the present invention is achieved like this: a kind of photovoltaic film terminal box, it comprises housing, external cable and line end Connection Block, described line end Connection Block is fixedly installed in enclosure interior, on the antetheca of described housing, offer wiring hole, described external cable is connected with line end Connection Block through wiring hole, on the diapire of described housing, offer installing hole, described installing hole is connected with wiring hole, in described installing hole, be provided with cable fixing block, thereby described cable fixing block and wiring hole are interlocked, external cable fixed.
The described cable fixing block left and right sides is provided with step, and described cable fixing block bottom is provided with latch.
Described wiring hole has two, and described two wiring holes left and right is arranged in juxtaposition.
The antetheca arranged outside of described housing has tubular configured joint, and the position of described tubular configured joint is corresponding with the position of wiring hole, on described tubular configured joint, is set with sealing shroud.
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 by cable fixing block, when external cable twisting or stretch when stressed, line end Connection Block can not be shifted thereupon or rock, can effectively prevent that diode from getting loose or breaking from line end Connection Block, the connection reliability of external cable and line end Connection Block improves greatly, has ensured stability and fail safe that terminal box is used.
