The utility model discloses when welding operation, only need the electric iron and need not to prepare in addition the solder flux, for welding operation provides convenient, can improve welded efficiency, the soldering tin piece that stores up in the tin face converges between area and the connecting terminal in entering after high temperature melts, and the quantity and the position of soldering tin all can be guaranteed, can improve the welded quality.
Description
Technical field
The utility model relates to field of photovoltaic power generation, specifically a kind of splicing ear structural design simplifying the photovoltaic junction box of welding operation.
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.Traditional photovoltaic junction box is ensure welding of convergent belt in box and splicing ear, and the scheme generally adopted is that convergent belt is carried out bending, then by this folding surface and splicing ear plane-welding, to reach welding object.Such scheme Problems existing is: 1, can produce resilience to a certain degree after the folding surface of convergent belt and splicing ear plane-welding, can reduce weld strength; 2, 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; 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 the need to carrying out bending to convergent belt, but by making folding surface on splicing ear, and adopt one to weld convergent belt auxiliary mould to prop up the folding surface of convergent belt and splicing ear, the position of convergent belt during welding is fixed, for welding operation provides conveniently, the efficiency of welding can be improved.The program also comes with some shortcomings, and when namely welding, workman needs a hand-held electric iron, and another hand-held scolding tin operates, and in the gap making scolding tin enter after high temperature melt between convergent belt and splicing ear, thus realizes the object of welding.The operation easier of the program is comparatively large, and the consumption of scolding tin, the position of scolding tin are also difficult to grasp.
Utility model content
In order to solve the problem, applicant, through Improvement, now provides a kind of photovoltaic junction box connecting terminals structure of convenient welding.
The technical solution of the utility model is as follows:
A photovoltaic junction box connecting terminals structure for convenient welding, described splicing ear comprises a subject plane, a storage tin face and a solder side, and described subject plane, storage tin face, solder side connect successively, and the position of solder side is lower than the position in storage tin face.
Further, described storage tin face has sagging storage molten tin bath, in described storage molten tin bath, is placed with soldering tin block.
Further, bending angle between described storage tin face and subject plane.
Further, bending angle between described solder side and storage tin face, or at same plane.
Further, described solder side is provided with projection, and described projection abuts with convergent belt.
Advantageous Effects of the present utility model is:
The utility model, owing to being provided with storage tin face and soldering tin block on splicing ear, therefore when welding operation, only needs electric iron instrument, and without the need to preparing solder flux in addition, for welding operation provides conveniently, can improve the efficiency of welding; Soldering tin block in storage tin face enters between convergent belt and splicing ear after high temperature melt, and the consumption of scolding tin and position all can be ensured, can improve the quality of welding.
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 structure chart of the present utility model.
Fig. 2 is the installation stereogram of the utility model in photovoltaic junction box.
Fig. 3 is the installation vertical view of the utility model in photovoltaic junction box.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Refer to Fig. 1, adopt the solder side 4 that each splicing ear 1 of the present utility model includes a subject plane 2, the storage tin face 3 formed by a lateral buckling certain slope of subject plane 2 and formed by a lateral buckling certain slope in storage tin face 3.In the embodiment shown in fig. 1, between subject plane 2 and storage tin face 3, bend a less gradient, and stored up between tin face 3 and solder side 4 and bend nearly 90 degree.Also can take to store up the scheme that tin face 3 and solder side 4 are the same face in addition, both bend common opposing body plane 2.Storage tin face 3 has sagging storage molten tin bath 5, in storage molten tin bath 5, is placed with soldering tin block 6.Solder side 4 has outstanding projection 7.
Refer to Fig. 2 and Fig. 3, splicing ear 1 of the present utility model is installed into the general structure after photovoltaic junction box as follows: photovoltaic junction box comprises the base and lid that can cover, one piece of base plate is installed in base, base plate is installed multiple splicing ear of the present utility model 1, between splicing ear 1, diode is installed, article two, cable is connected through the briquetting be arranged in base one end with splicing ear 1, the other end of splicing ear 1 welds convergent belt 8 respectively, supports convergent belt 8 to splicing ear 1 in weldering convergent belt auxiliary mould 9 mounting seat.
Be installed on the weldering convergent belt auxiliary mould 9 in base, itself and position base are fixed, and between the solder side 4 being in base and splicing ear 1, and also projection is provided with on the side towards solder side 4.Convergent belt 8 is clipped between solder side 4 and weldering convergent belt auxiliary mould 9.One side surface of convergent belt 8 abuts with the projection 7 on solder side 4, and opposite side surface abuts with the projection on weldering convergent belt auxiliary mould 9.
During welding, with electric iron heating storage tin face 3, the soldering tin block 6 in the storage molten tin bath 5 in storage tin face 3 is at high temperature melted, and flows between convergent belt 8 and solder side 4 along the storage tin face 3 tilted, complete welding.
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.
