Description

The Welding Structure of terminal and convergent belt in a kind of photovoltaic junction box
Technical field
The utility model relates to field of photovoltaic power generation, is specifically related to a kind of Welding Structure for the terminal in the photovoltaic junction box of photovoltaic generating system and convergent belt.
Background technology
In the electric connection technology of photovoltaic generating system, employing photovoltaic junction box realizes the electrical connection between photovoltaic module and inverter usually.The structure of common photovoltaic junction box is as follows: comprise the base and lid that mutually cover, mounting base in base, mounting terminal on base plate, terminal installs diode, and cable is connected with terminal through the briquetting be arranged in base, by convergent belt and terminal soldering.Electric charge is collected in the effect of convergent belt, is connected by often a string electric current, collects output.For ensureing that convergent belt is good with welding of terminal, need enough welding contact-making surfaces, the scheme generally adopted at present is that convergent belt is carried out bending, then by this folding surface and terminal plane-welding, to reach welding object.Such scheme Problems existing is: one, can produce resilience to a certain degree after the folding surface of convergent belt and terminal plane-welding, can reduce weld strength; Two, during welding, the position of convergent belt is not fixed, and can produce movement, increases welding operation difficulty, and welding quality is difficult to ensure; Three, add one bending process more, affect production efficiency.
Utility model content
In order to solve the problem, applicant, through Improvement, now provides the Welding Structure of terminal and convergent belt in a kind of photovoltaic junction box.
The technical solution of the utility model is as follows:
A Welding Structure for terminal and convergent belt in photovoltaic junction box, comprising:
Multiple terminal, is installed in photovoltaic junction box base, the solder side that each terminal includes a subject plane and formed near a lateral buckling of convergent belt by described subject plane;
Welding tooling, is arranged between photovoltaic junction box base and the solder side of terminal, and the position base of itself and photovoltaic junction box is fixed;
Multiple convergent belt, one side forms gap with corresponding terminal solder side, and the solder of welding is poured in described gap; The another side of described convergent belt abuts with welding tooling.
Its further technical scheme is: the bending angle between the solder side of described terminal and subject plane is 90 ~ 110 degree.
And its further technical scheme is: described solder side is provided with the first kind projection; Described welding tooling is provided with the second kind projection on the side towards terminal soldering junction.
Advantageous Effects of the present utility model is:
The utility model makes folding surface on terminal, and without the need to carrying out bending to convergent belt, and adopt a welding tooling to prop up convergent belt and terminal, the position of convergent belt during welding is fixed, for welding operation provides conveniently, the efficiency of welding can be improved; Meanwhile, make between convergent belt and terminal, to form solder flux seam by the projection on folding surface, ensure the groundwater increment of solder flux, the intensity of welding can be improved; Further, under the effect of surface tension of liquid, solder flux can remain between convergent belt and terminal and not leak.
Advantage of the present utility model provides in the description of embodiment part below, and part will become obvious from the following description, or be recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is the exploded view of the photovoltaic junction box adopting technical solutions of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the sectional view of the photovoltaic junction box adopting technical solutions of the utility model.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Refer to Fig. 1, adopt the general structure of the photovoltaic junction box of technical solutions of the utility model as follows: to comprise the base 2 and lid 1 that can mutually cover for a pair, one piece of base plate 3 is installed in base 2, base plate 3 is provided with multiple terminal 7, between multiple terminal 7, diode 6 is installed, article two, cable 9 is connected with terminal 7 through two briquettings 8 be arranged in base 2, and the other end of each terminal 7 is welded with convergent belt 5 respectively, abuts in welding tooling 4 mounting seat 2 with each convergent belt 5.
Refer to Fig. 2, Fig. 3 and Fig. 4, be installed on each terminal 7 in base 2, the solder side 7b including a subject plane 7a and formed near the lateral buckling about 90 ~ 110 degree of convergent belt 5 by this subject plane 7a, solder side 7b is extruded with a projection 7c.Be installed on the welding tooling 4 in base 2, itself and base 2 position are fixed, and between the solder side 7b being in base 2 and terminal, and on the side towards terminal soldering junction 7b, be provided with multiple projection 4a.The quantity of convergent belt 5 is equal with the quantity of terminal 7, and position is clipped between the solder side 7b of terminal and welding tooling 4.A surface of convergent belt 5 abuts with the projection 7c on terminal soldering junction 7b, and another surface abuts with the projection 4a on welding tooling 4.Projection 7c makes to form the gap of pouring into solder between the solder side 7b of convergent belt 5 and terminal.
Installation procedure of the present utility model and action principle are: first installed by terminal 7, and the solder side 7b then against terminal places convergent belt 5, puts into welding tooling 4 simultaneously.Put into the process of welding tooling 4, convergent belt 5 props up by the projection 4a on welding tooling 4, and its direction towards the solder side 7b of terminal is moved, until make convergent belt 5 withstand projection 7c on the solder side 7b of terminal, thus welding tooling 4 is interfered mutually with terminal 7 with convergent belt 5, convergent belt 5.Finally, between convergent belt 5 and the solder side 7b of terminal, pour into scolding tin to weld.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection range of the present utility model.
