Description
Technical field
The present invention relates to electronic component technology field, especially relate to a kind of photovoltaic junction box being easy to assemble.The invention still further relates to the preparation method that this is easy to the photovoltaic junction box assembled.
Background technology
Photovoltaic junction box application is convenient, simple, thus in photovoltaic industry, obtain extensive employing.But the photovoltaic junction box used now is master mainly with assembling parts in assembling mode.That is, the parts such as base, body frame, diode are assembled one by one, thus comparatively loaded down with trivial details, and assembly quality is difficult to ensure.
Summary of the invention
The object of this invention is to provide a kind of photovoltaic junction box being easy to assemble, it has total quality preferably feature.The invention also discloses the preparation method that this is easy to the photovoltaic junction box assembled.
First technical scheme of the present invention is: be easy to the photovoltaic junction box assembled, comprise base and upper cover, hardware is provided with in this base, this hardware front end is welded with diode, rear end is electrically connected with 2 connectors, described diode adopts the chip diode of TO-263 encapsulation, this diode is electrically connected with this hardware by the mode of Reflow Soldering, simultaneously, this hardware adopts copper sheet preparation, this hardware is fixed in a holder, between the edge of this hardware and the edge of this holder, there is tunnel, and, this holder is fixed on this base, this base is penetrating up and down, this holder is provided with the briquetting be pressed in by this connector on this hardware.
Angle α between the bearing of trend of described 2 connectors is: 35 °≤α≤50 °.
The advantage being easy to the photovoltaic junction box assembled of the present invention is: be easy to assembling.The photovoltaic junction box being easy to assemble of the present invention adopts modularized design to a certain extent, when it is prepared can by diode and hardware in advance assembly welding become module, finally entirety is loaded in base, thus improves overall efficiency of assembling.
Second technical scheme of the present invention is: this is easy to the preparation method of the photovoltaic junction box assembled, the described installation step being easy to the photovoltaic junction box assembled is: first this diode is welded into module by the mode of Reflow Soldering and this hardware, then by the mode of thermofussion welding, module is fixed on this holder, then this holder is connected in this base, afterwards by the mode of electric resistance welding by the cable welding of this connector on this hardware, this briquetting is fixed on this holder by the mode finally by ultrasonic bonding.
The preparation method being easy to the photovoltaic junction box assembled of the present invention passes through optimize connected mode and optimize assemble sequence, not only ensure this photovoltaic junction box and there is preferably quality on the whole, and prepared according to modular mode, reduce the assembly difficulty of this photovoltaic junction box, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
In figure:
10, base;
20, upper cover;
30, hardware;
40, diode;
50, connector;
60, holder;
70, briquetting.
Embodiment
Embodiment, as shown in Figure 1: be easy to the photovoltaic junction box assembled, comprise base 10 and upper cover 20.Be provided with hardware 30 in this base 10, this hardware 30 front end is welded with diode 40, rear end is electrically connected with 2 connectors 50, the rear end of this connector 50 extend out to outside this base 10.Further say, the chip diode that this diode 40 adopts TO-263 to encapsulate, this diode 40 is electrically connected with this hardware 30 by the mode of Reflow Soldering.Meanwhile, this hardware 30 adopts copper sheet to prepare.That is, this diode 40 and this hardware 30 form modularization, to improve assembling speed.Like this, ensure the consistency that this diode 40 welds to improve product quality.And, adopt the chip diode of TO-263 encapsulation that this diode 40 is fully fitted with copper sheet after welding.This hardware 30 is fixed in a holder 60.There is between the edge of this hardware 30 and the edge of this holder 60 tunnel (not shown on figure).That is, between the edge of this hardware 30 and the edge of this holder 60, there is gap, to increase creepage distance, make it can reach system voltage scope and be up to about 1000V.And this holder 60 is fixed on this base 10, and this base about 10 is penetrating.Like this, not only save plastic material, and the radiating effect of hardware 30 prepared by copper sheet is better.This holder 60 is also provided with the briquetting 70 be pressed in by this connector 50 on this hardware 30.
Further say, the angle α between the bearing of trend of these 2 connectors 50 is: 35 °≤α≤50 °.More excellent, the angle α between the bearing of trend of these 2 connectors 50 is 45 °.Like this, in-site installation is facilitated.
This is easy to the preparation method of the photovoltaic junction box assembled, except the step such as moulding process of routine, this installation step of photovoltaic junction box being easy to assemble is: first this diode 40 is welded into module by the mode of Reflow Soldering and this hardware 30, then by the mode of thermofussion welding, module is fixed on this holder 60, then this holder 60 is connected in this base 10, afterwards by the mode of electric resistance welding by the cable welding of this connector on this hardware 30, this briquetting 70 is fixed on this holder 60 by the mode finally by ultrasonic bonding.Like this, give full play to the advantage of various welding procedure, made this photovoltaic junction box quality more stable, and by optimizing installation step, having given full play to the advantage of modular assembly, having greatly improved production efficiency.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
