The utility model solves the technical scheme that its technical problem adopts: a kind of plug-in type photovoltaic cell component terminal box, comprise by the receptacle portion of each busbar of photovoltaic cell component access insulated from each other with by the plug box of power transmission cable sealing access, opening of described plug box and can cover receptacle portion, in plug box, there is the intercalation part matching with described receptacle portion, described intercalation part has the binding post with quantity such as described busbars, between adjacent binding post, be connected with diode, the binding post at two ends respectively with power transmission cable just, negative pole is connected, described binding post and busbar conducting, plug box and receptacle portion are pegged graft and are sealed on the backboard that is fixed on photovoltaic cell component.
And busbar is provided with the conducting portion of binding post the elastic pressure parts that both are reliably contacted, guarantee effectively conducting between busbar and binding post.
The integrative-structure that intercalation part and plug box are injection mo(u)lding.
In order better to improve the radiating effect of terminal box, each binding post lower end is also connected with radiating copper sheet, and diode is arranged in radiating copper sheet.
Further, a part for diode thickness direction and the pin of diode embed plug box, and the pin of diode is between radiating copper sheet and plug box.
The beneficial effects of the utility model are: the plug-in type photovoltaic cell component terminal box method that the utility model provides, simple in structure, without the encapsulating of windowing add a cover, easy for installation, save man-hour and labor and materials, significantly reduced making and the installation cost of terminal box.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Plug-in type photovoltaic cell component terminal box as shown in Figures 1 to 4, comprises by the receptacle portion 6 of each busbar 7 accesses insulated from each other of photovoltaic cell component with by the plug box 1 of power transmission cable 4 sealing accesses.Power transmission cable 4 and outside lead-out terminal 13 connections.By 12 bonding connections of 3M two-sided tape, fixing by fluid sealant 9 sealings between plug box 1 bottom surface and the backboard 8 of photovoltaic cell component between the backboard 8 of receptacle portion 6 and photovoltaic cell component, install simple and cost-saved.
1 one openings of plug box and can cover receptacle portion 6, have the intercalation part 5 matching with described receptacle portion 6 in plug box 1.Preferably, intercalation part 5 is the integrative-structure of injection mo(u)lding with plug box 1, reduces the operation of additionally making respectively intercalation part 5 and plug box 1, simplifies work flow, has effectively reduced the cost of manufacture of terminal box.
Described intercalation part 5 has the binding post 2 for the treatment of the quantity such as busbar 7 of wiring with the backboard 8 of photovoltaic cell component.Binding post 2 is provided with busbar 7 conducting portions the elastic pressure parts 11 that both are reliably contacted, and guarantees effectively conducting between busbar 7 and binding post 2.In order to guarantee better the electric connection of busbar 7 and binding post 2, elastic pressure parts 11 can embed and be fixed in receptacle portion 6, and elastic pressure parts 11 suppresses busbar 7 and binding post 2 to be fitted and connected.In addition, the electric connection mode of busbar 7 and binding post 2 is not limited in by elastic pressure parts 11 suppresses laminating, also can realize by other technologies means, only needs binding post 2, busbar 7 after patching, to be adjacent to and forms path.
Between adjacent binding post 2, be connected with diode 3, the binding post 2 at two ends is connected with the positive and negative electrode of power transmission cable 4 respectively.In order better to improve the radiating effect of terminal box, each binding post 2 lower end is also connected with radiating copper sheet 10, and diode 3 is arranged in radiating copper sheet 10.Further, a part for diode 3 thickness directions and the pin of diode 3 14 embed plug box 1, and the pin 14 of diode 3 is between radiating copper sheet 10 and plug box 1.Preferably, 1/4th of diode 3 self thickness embeds plug boxes 1, and what 10 of radiating copper sheet had self thickness at least partly embeds plug box 1.
The heat that during work, diode 3 produces can conduct to backward outer the distributing of plug box 1 by pin 14, radiating copper sheet 10, and plug box 1 is structure as a whole with intercalation part 5, further improves loose heat conducting area, is convenient to effectively outwards heat radiation.The terminal box internal heat dissipating so arranging is good, and working temperature can be stabilized in critical field, and compared to the terminal box of traditional metal material, the cost of manufacture of terminal box significantly reduces.
When the plug-in type photovoltaic cell component terminal box of so design is installed, only need receptacle portion 6 fixedly be sticked on the backboard 8 of photovoltaic cell component by 3M two-sided tape 12, then busbar 7 laminatings for the treatment of wiring on backboard 8 are located to elastic pressure parts 11 surfaces in receptacle portion 6, 1 respective socket portion 6 positions of the plug box with binding post 2 and intercalation part 5 that then bottom are coated with to fluid sealant 9 patch and plug box 1 is pressed to fluid sealant 9 fits completely with the backboard 8 of photovoltaic cell component, binding post 2 is electrically connected good with busbar 7, can complete photovoltaic cell component terminal box is installed.After backboard 8 laminatings of plug box 1 and photovoltaic cell component, directly formed hermetic state, plug box 1 surface is also without offering in addition window, without to plug box 1 encapsulating or add a cover in addition.The photovoltaic cell component terminal box that the mode that this employing patches is made and installed has not only been saved labor and materials, also saved man-hour, simplified installation procedure, can make terminal box be fixed in time on the backboard 8 of photovoltaic cell component, before avoiding 8 fluid sealants of backboard 9 of terminal box and photovoltaic cell component to solidify, terminal box is subjected to displacement, and is more convenient to install and improve installation accuracy.
Above-mentioned execution mode is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
