Abstract

Disclosed is waterproof junction box which comprises a base, a cover, and a vent valve. The blow valve comprises a first circular column, a second circular column, and a waterproof breathable film. The first circular column and the second circular column are both hollow. The first circular column is disposed on the surface of the cover and towards the base, and a first inner hole and a bottom of the first inner hole are disposed inside the first circular column. The bottom of the first inner hole is provided with an open zone, and the first inner hole is larger than the open zone. The hole wall of the first inner hole forms a first screw thread, and the bottom of the hole wall of the first inner hole is provided with an annular flange. The surface of the second circular column forms a second screw thread. The second screw thread and the first screw thread are capable of being rotationally connected together. The first circular column accommodates the second circular column. When the second circular column is screwed into the first circular column, the waterproof breathable film is fixed. The junction box of the utility model has a waterproof function.

Description

Waterproof junction box
Technical field
The utility model relates to terminal box, especially a kind of waterproof junction box.
Background technology
Supply falls short of demand owing to the energy, and many countries more and more pay close attention to the application of solar cell.Without any pollution, so solar cell industry development rapidly to environment for solar energy.The voltage that single solar cell provides is low, and electric current is little, but by terminal box the solar cell serial or parallel connection is connected, and can form high voltage and heavy current.Because solar cell in outdoor application, when raining or there was dampness in the air, damages solar cell easily.
Summary of the invention
The purpose of this utility model is: the terminal box that a kind of waterproof is provided.
The technical solution adopted in the utility model is: waterproof junction box comprises pedestal, lid and ventilation valve.Breather valve comprises first cylinder, second cylinder and waterproof ventilated membrane.First cylinder and second cylinder are hollow.First cylinder is arranged on the surface of lid towards base, and there are first endoporus and bottom in inside.Open zone is arranged at the bottom, and first endoporus is greater than open zone.Form first screw thread on the hole wall of first endoporus, annular flange flange is arranged on the bottom.Second periphery forms second screw thread, and second screw thread and first screw thread can be rotatably connected, and second cylinder is taken in first cylinder.When second cylinder was screwed into first cylinder, waterproof ventilated membrane was fixed.
Second cylindrical first end is provided with the corresponding first cylindrical annular flange flange of cannelure.Two ends of annular flange flange are fixed by two projections respectively, and projection stretches into cannelure.Waterproof ventilated membrane and is bonded on second cylindrical first end between second cylindrical first end and the first cylindrical bottom.When second cylinder was screwed into first cylinder, waterproof ventilated membrane was fixed.
The first cylindrical annular flange flange and the second cylindrical cannelure axially arrange along open area, so waterproof ventilated membrane can be at open area outside axial restraint, the developing zone is covered fully by waterproof ventilated membrane.When the pressure balance of terminal box inner air and outer air, waterproof ventilated membrane can prevent that sealing enters.
The beneficial effects of the utility model are: the terminal box that provides has waterproof action.

Fig. 2 is the terminal box base that provides of the utility model and the decomposition view of ventilation valve.
Fig. 3 is the cross-sectional view of the terminal box ventilation valve that provides of the utility model.
Number in the figure shows: 1 pedestal, 2 second cylinders, 3 waterproof ventilated membranes, 4 bases, 5 lids, 6 breather valves, 11 zones, 12 bottoms, 13 first endoporus, 14 first screw threads, 15 annular flange flange, 21 first ends, 22 second ends, 23 second endoporus, 24 second screw threads, 25 cannelures, 26 lids, 151 projections, 152 projections, D distance, S1 pitch, S2 pitch, T1 thickness.
Embodiment
As depicted in figs. 1 and 2, terminal box 10 comprises base 4, is installed in pedestal 1, lid 5 and breather valve 6 on the base 4.Breather valve 6 comprises that first cylinder 1, second cylinder 2 and waterproof ventilated membrane 3, the first cylinders 1 and second cylinder 2 are hollow.First cylinder 1 is arranged on and covers 5 surface towards base 4, and there are first endoporus 13 and bottom 12 in inside.There are open zone 11, the first endoporus 13 bottom 12 greater than open zone 11.Form first screw thread 14 on the hole wall of first endoporus 13, annular flange flange 15 is arranged on the bottom 12.Second cylinder, 2 surfaces form second screw thread, 24, the second screw threads 24 and first screw thread 14 can be rotatably connected, in second cylinder, 2 incomes, first cylinder 1.Second cylinder 2 comprises first end 21, second end 22 and second endoporus 23.Second end 22 of second cylinder 2 comprises and covers 26 that when second cylinder 2 was screwed into first cylinder 1, lid 26 was stayed the outside.
Fig. 3 is the cross-sectional view of the ventilation valve 6 of terminal box 10.First end 21 of second cylinder 2 is provided with the annular flange flange 15 of cannelure 25 corresponding first cylinders 1.Two ends of annular flange flange 15 are fixed by two projections 151 and 152 respectively, and projection 151 and 152 stretches into cannelure 25.Waterproof ventilated membrane 3 and is bonded on first end 21 of second cylinder 2 between the bottom 12 of first end 21 of second cylinder 2 and first cylinder 1.When second cylinder 2 was screwed into first cylinder 1, waterproof ventilated membrane 3 was fixed.
The annular flange flange 15 of first cylinder 1 and the cannelure 25 of second cylinder 2 axially arrange along open area 11, so waterproof ventilated membrane 3 can be at open area 11 outside axial restraints, developing zone 11 is covered fully by waterproof ventilated membrane 3.When terminal box 10 inner air and outer air pressure balances, waterproof ventilated membrane 3 can prevent that sealing enters.The top of the annular flange flange 15 of first cylinder 1 and the cannelure 25 of second cylinder 2 forms a specific distance B less than the pitch S1 of first screw thread 14, and distance B is less than the half pitch S2 of first screw thread 14.The thickness T 1 of waterproof ventilated membrane 3 is greater than distance B.Distance B can be suitably fixing waterproof ventilated membrane 3, avoid waterproof ventilated membrane 3 to be subjected to the injury of second screw thread 24.
