Description
Technical field
The invention belongs to photovoltaic junction box technical fields, more particularly, to a kind of high leakproofness photovoltaic junction box.
Background technique
High leakproofness photovoltaic junction box is a component indispensable in photovoltaic generating system, is that photovoltaic module can be just
Often the key element of conveying electric energy, conventional high leakproofness photovoltaic junction box are mounted on the back side of photovoltaic module outward, use
It draws, is electrically connected with being realized with adjacent photovoltaic module, to be concatenated into outward in by the positive and negative anodes exit of photovoltaic module
Entire photovoltaic generating system；Existing high leakproofness photovoltaic junction box because busbar grafting position the reason of, there are sealing effects
Difference, volume is bigger than normal, and installation is inconvenient, the big and at high cost disadvantage of the space occupied.
Summary of the invention
For overcome the deficiencies in the prior art, it is good to provide a kind of sealing effect, small in size, easy-operating high leakproofness light by the present invention
Lie prostrate terminal box.
To achieve the goals above, the present invention uses following technical scheme：A kind of high leakproofness photovoltaic junction box, including bottom
Seat, lid, is set to the intracorporal multiple diodes of the box, cable, conductive sheet and briquetting at the box body being connected with the pedestal；Institute
Pedestal is stated equipped with multiple busbar sockets, which is set to the middle of the base；Pressure spring is equipped in the box body, it should
Pressure spring is located above the reflux socket；The pressure spring includes fixed part and the press section that is connected with the fixed part, described to press
Splenium and the fixed part junction, which are equipped with, prevents turning over protrusion, described to prevent that turn over protrusion matches with the pedestal；The box body and lid
Sealant pouring and sealing structure is equipped between body.Busbar socket by being set to the middle part of pedestal, therefore the two sides of box body by the present invention
Space is vacated, and it makes use of the spaces in the middle part of terminal box, is saved to entire terminal box space, and which can be convenient for
Enough spacing are able to maintain in the case where box body small volume between diode, convenient for heat dissipation, thus the volume of entire box body
It is programmable smaller, reduce the cost of entire box body；Prevent turning over protrusion by being arranged on pressure spring, when pressure spring outwardly opens,
It is anti-turn over protrusion can be inconsistent with the upper surface of pedestal, so that pressure spring after moving to certain angle, can not turn over again, pressure
Spring is stablized in predeterminated position, to simplify the operation to pressure spring, need to only press down on, facilitate operation, likewise, because of pressure spring
It can not overturn, therefore the end of its bending will not improve the safety from operation upward；By the way that sealant pouring and sealing structure is arranged, mention
The high sealing waterproof performance of terminal box, so that terminal box is suitable for outdoor harsh weather.
Further, the sealant pouring and sealing structure include glue-filling slot on the box body, be set on the lid with
Encapsulating mouth that the glue-filling slot matches and prevent casting glue from overflowing the seal assembly of glue-filling slot；By pouring into casting glue, significantly
The sealed waterproof effect of terminal box is improved, while making box body closer in conjunction with lid, and then ensure that terminal box to room
The adaptability of outer harsh weather improves the service life of product.
Further, the seal assembly includes the first card slot being set on box body and the second card slot and first card
The first inserted sheet that slot matches, the second inserted sheet matched with second card slot, the first sealing on the outside of the first inserted sheet
Circle and the second sealing ring on the inside of the second inserted sheet；By the mutual cooperation of inserted sheet and card slot, so that the knot of box body and lid
Close it is even closer, while play prevent casting glue overflow effect, avoid casting glue and enter tray interior and influence inside
The operation of element；By the way that double-layer seal rings are arranged, the effect of sealing waterproof is externally played, extends product service life, internally
Prevent casting glue from overflowing, duplicate protection.
Further, multiple channels are equipped between the encapsulating slot and first card slot；It is connected to by the way that channel is arranged
Encapsulating slot and the first card slot, when so that box body being connected with lid, casting glue can touch the first inserted sheet, so that box body and lid
The connection of body is stronger.
Further, the diode is equipped with welding protrusion, and the conductive sheet is equipped with to match with the welding protrusion
The welding recess portion of conjunction；Setting welding protrusion and welding recess portion make between diode and conductive sheet so that diode accurately welds
Good connecting effect, conductive effect are strong.
Further, the box body is equipped with the first locating slot matched with the cable, and the briquetting is set to described
In first locating slot；The first locating slot, which is arranged, to position cable, so that briquetting is when being fixed locating slot, it is fixed
Effect is good.
Further, the briquetting is equipped with the second locating slot matched with the cable；Second locating slot can be with
A positioning groove matches, and a complete cylindrical chamber is formed, thus to the good fixing effect of cable.
Further, it is equipped with multiple first convex ribs in first locating slot, multiple the are equipped in second locating slot
Two convex ribs, first convex ribs are matched with the cable with second convex ribs；First convex ribs and the second convex ribs are set,
When briquetting is fixed to cable, good squeezing effect can be realized, therefore to the good fixing effect of cable.
Further, first convex ribs are arranged along first positioning groove length direction, and second convex ribs are described in
The setting of second positioning groove length direction；First convex ribs and the second convex ribs are set as being arranged along the length direction of slot, for along line
The length direction of cable, thus it is big with cable contact area, and the frictional force and squeezing effect to cable are good.
In conclusion busbar socket is arranged at the middle part of pedestal in the present invention, therefore busbar will be installed in pedestal
The space in the middle part of terminal box is utilized in portion position, saves entire terminal box space, so that the volume of entire box body is programmable more
Small, box body cost reduces；It is arranged after preventing that turning over protrusion makes pressure spring move to certain angle on pressure spring, can not overturns again backward, letter
Change and pressure spring is operated, need to only press down on；By the way that sealant pouring and sealing structure is arranged, the sealing waterproofness of terminal box is improved
Can, so that terminal box is suitable for outdoor harsh weather.
