Description
Technical field
This utility model relates to field of photovoltaic power generation, specifically the terminal structure of the photovoltaic junction box of a kind of convenient welding.
Background technology
In the electric connection technology of photovoltaic generating system, photovoltaic junction box is generally adopted to realize the electrical connection between photovoltaic module and inverter. Traditional photovoltaic junction box is ensure welding of convergent belt in box and terminal, it is common to the scheme of employing is that convergent belt carries out bending, then by this folding surface and terminal plane-welding, to reach to weld purpose. Such scheme there is the problem that 1, can produce a degree of resilience after the folding surface of convergent belt and terminal plane-welding, can reduce weld strength; 2, during welding, the position of convergent belt is not fixed, and can produce mobile, increase welding operation difficulty, and welding quality is difficult to ensure that; 3, add one bending process more, affect production efficiency.
The applicant once proposed the Welding Structure of terminal and convergent belt in a kind of photovoltaic junction box in Chinese patent " 2015206233772 ", it is without carrying out bending to convergent belt, but by making folding surface on terminal, and adopt a weldering convergent belt auxiliary mould to prop up the folding surface of convergent belt and terminal, the position of convergent belt during welding is made to fix, provide conveniently for welding operation, it is possible to improve the efficiency of welding. The program there is also some shortcomings, and when namely welding, workman needs a hand-held flatiron, and another hand-held scolding tin is operated, and makes scolding tin enter after high temperature melt in the gap between convergent belt and terminal, thus realizing the purpose of welding. The operation easier of the program is relatively big, the consumption of scolding tin, scolding tin position be also difficult to grasp.
Utility model content
In order to solve the problems referred to above, applicant, through Improvement, now provides a kind of photovoltaic junction box terminal with reserved stannum.
The technical solution of the utility model is as follows:
A kind of photovoltaic junction box terminal with reserved stannum, described terminal includes a subject plane and the solder side formed by described subject plane near a lateral buckling of convergent belt, bending angle between described subject plane and solder side is 70��110 degree, and described solder side is placed with reserved stannum.
Further, described solder side is provided with projection or preformed groove, and described reserved stannum wraps up projection or is placed in preformed groove.
Advantageous Effects of the present utility model is:
This utility model, owing to placed reserved stannum on the solder side of terminal, therefore only needs flatiron when welding operation, without additionally preparing solder flux, provides conveniently for welding operation, it is possible to improve the efficiency of welding; After flatiron is put on reserved stannum, reserved stannum high temperature melt enters between terminal solder side and convergent belt, and the consumption of scolding tin and position all can be ensured, it is possible to improve welding quality.
Advantage of the present utility model provides in the description by detailed description of the invention part below, and part will become apparent from the description below, or is recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structure chart after this utility model removes reserved stannum.
Fig. 2 is complete structure figure of the present utility model.
Fig. 3 is this utility model installation diagram in photovoltaic junction box.
Fig. 4 is this utility model installation sectional view in photovoltaic junction box.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Referring to Fig. 1 and Fig. 2, each terminal 1 of the present utility model all includes a subject plane 2 and the solder side 3 formed by a nearly right angle of lateral buckling of subject plane 2. In embodiment shown in Fig. 1 and Fig. 2, between subject plane 2 and solder side 3, it is bent to 90 degree. As it is shown in figure 1, be provided with sagging preformed groove 4 on solder side 3, in preformed groove 4, it is placed with reserved stannum 5; Or the projection 6 of several projections can also be set in solder side 3. The effect arranging projection 6 has 2 points, one is to make the reserved stannum 5 being placed on solder side 3 form enclosed mass as shown in Figure 2, two is that projection 6 abuts the space forming certain altitude with convergent belt 7 surface when welding, enters this space, thus ensureing the thickness of scolding tin after reserved stannum 5 high temperature melt.
Refer to Fig. 3 and Fig. 4, population structure after terminal 1 of the present utility model is installed into photovoltaic junction box is as follows: photovoltaic junction box includes base and the lid that can cover, one piece of base plate is installed in base, base plate is installed multiple terminal of the present utility model 1, diode is installed between terminal 1, the briquetting that two lines cable is passed through in base is connected with one end of terminal 1, the other end of terminal 1 props up convergent belt 7, weldering convergent belt auxiliary mould 8 inserts between convergent belt 7 and base, makes convergent belt 7 be adjacent to the solder side 3 of terminal 1.
Referring to Fig. 3 and Fig. 4, during welding, flatiron welded header is placed directly on after the reserved Xi5Chu of the solder side 3 of terminal 1 is adjacent to 1.5��2 seconds and removes, the reserved stannum 5 of flatiron heating, makes reserved stannum 5 high temperature melt, flows between convergent belt 7 and solder side 3, and scolding tin completes.
Above-described is only preferred implementation of the present utility model, and this utility model is not limited to above example. It is appreciated that the oher improvements and changes that those skilled in the art directly derive under the premise without departing from spirit of the present utility model and design or associate, is all considered as being included within protection domain of the present utility model.
