Fig. 2 is the structural representation of the utility model insulating body shown in Figure 1;
Fig. 3 is the structural representation of the utility model cover shown in Figure 1.
Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
See also Fig. 1, the solar junction box 1 of the utility model good water-proof effect comprises an insulating body 10, a cover 20 that matches with described insulating body 10, is located at electric elements (not shown) and solidus device (not shown) in the described insulating body 10.
See also Fig. 1 to Fig. 3, described insulating body 10 is provided with an opening towards described cover 20 and roughly rectangular receiving space 11.Described electric elements and solidus device are contained in the described receiving space 11.One sidewall of described receiving space 11 is provided with two wire holes 12 that run through described sidewall and space.The side of described insulating body 10 outwards convexes with first engaging lug 13 of some spaces.Described first engaging lug 13 be provided with one run through described first engaging lug 13 up and down run through groove 131.The described sidewall that runs through groove 131 is provided with one and extends and exceed the clamping part 14 of described first engaging lug, 13 top edges towards cover 20.The end of described clamping part 14 stretches out and is formed with a pothook 141.Described cover 20 is provided with some described cover 20 and rounded air-vents 21 of running through.Described air-vent 21 is roughly rounded arrangement on described cover 20.Described air-vent 21 places are provided with the film (not shown) of unidirectional seepage.The groove 22 that the medial surface of described cover 20 is concaved with a circle and is connected with described air-vent, described film is located in the described groove 22.The edge of described cover 20 stretch out be formed with some spaces and with described first engaging lug, 13 corresponding second engaging lugs 23.Described second engaging lug 23 is provided with a buckle slot 231 that runs through described second engaging lug 23 up and down and match with described clamping part 14.Described pothook 141 is arranged in the described buckle slot 231.
Please continue to consult Fig. 1 to Fig. 3, in use, at first described electric elements and solidus device are located in the receiving space 11 of described insulating body 10.One end of cable is located on the described solidus device, and described wire hole 12 is passed to stretch out described receiving space 11 in the opposite end of described cable.Since solar junction box more than 1 in the open air, outside work, so need the good structure of water resistance.Need very dry environment to satisfy the conduction demand of electric elements in the solar junction box 1 in the described solar junction box 1.After solar junction box 1 assembling, except that air-vent 21 all-sealed structure in the solar junction box 1.Described air-vent 21 is provided with the film of unidirectional seepage, thereby can stop solar junction box 1 outer water to infilter in the solar junction box 1 to play waterproof effect preferably; And the water vapour in the solar junction box 1 can by described film outside solar junction box 1 seepage to satisfy airing function.Thereby the solar junction box 1 of the utility model good water-proof effect not only air permeable effect is good but also increased good waterproof effect greatly.
