Background technology
Solar energy is renewable resource, converts solar energy into electrical energy both energy savings and alleviation power shortage, can reduce environmental pollution again.Therefore, solar-photovoltaic technology is more and more subject to concern and the favor of the public.
Solar cell produces photoelectric material, and it utilizes photovoltaic effect that transform light energy is become electric energy.At present, photovoltaic module is widely used in structure electricity generation system, or for as building curtain wall or to be installed on the roof of building first-class.
Photovoltaic junction box for realizing the interconnected of photovoltaic module and external power source assembly, by the power stage of photovoltaic module to outside.The more important thing is, photovoltaic component terminal box is also the bypass protector of photovoltaic module.When photovoltaic module internal cell occur hidden split or blocked by shade time produce hot spot effect, photovoltaic module generation hot spot effect place temperature sharply raises, if now none-disk terminal protective device, is easily burnt by photovoltaic module and even threatens whole photovoltaic plant.
Photovoltaic module is connected with terminal box by the convergent belt of drawing, and usual manner takes metal clamping or add tin welding mode to connect.But metal snap fit As time goes on, the elastically-deformable spring leaf of its generation effect produces mechanical fatigue gradually, is easy to cause convergent belt to loosen and even departs from; And adding for tin welding convergent belt for routine, present module manufacturer major part by manual operation, and is difficult to detect whether occur rosin joint, once there is rosin joint, probably produces arc spark under assembly power generation situation, threatens the safety of photovoltaic module.
Summary of the invention
The purpose of this utility model is to provide a kind of photovoltaic junction box with bypass integration module, and it has parts and connects comparatively tight, and work is feature comparatively reliably.
The technical scheme that the utility model adopts is: the photovoltaic junction box with bypass integration module, comprise box body and lid, photovoltaic bypass module is provided with in this box body, this photovoltaic bypass module is electrically connected with cable and convergent belt, the other end of this cable extends outside this box body, simultaneously, casting glue is filled with in this box body, described photovoltaic bypass module has installing hole, and the bottom of this box body is provided with the pilot hole aligned with installing hole, one end of this convergent belt is successively connected in this photovoltaic bypass module by the mode of soldering through after pilot hole and corresponding installing hole.
The guide vane end stop of the back-up block supporting this photovoltaic bypass module and the avris being stuck in this photovoltaic bypass module is provided with in described box body.
Described cable is welded in this photovoltaic bypass module by the mode of medium frequency welding.
The outer surface of described cable is fixed on this box body by ultrasonic technique.
Described photovoltaic bypass module is the anti-photovoltaic bypass module filling technique and prepare.
The utility model is advantageously: parts connect comparatively tight, work comparatively reliable.The photovoltaic junction box with bypass integration module of the present utility model is when installing convergent belt, convergent belt is through pilot hole and installing hole, ensure that the correct of installation and conveniently then improve production efficiency, and the mode combined with soldering is fixed by installing hole, make the connection of convergent belt comparatively firm, improve reliability and the useful life of terminal box work.And, by the mode of preferred weld, make the connection of cable also comparatively firm, improve the reliability of product work further.

Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: the photovoltaic junction box with bypass integration module, comprises box body 10 and covers the lid 20 on this box body 10.Photovoltaic bypass module 30 is provided with in this box body 10.This photovoltaic bypass module 30 is electrically connected with cable 40 and convergent belt (not shown on figure), and the other end of this cable 40 extends outside this box body 10.Meanwhile, casting glue (not shown on figure) is filled with in this box body 10.
Further say, shown in composition graphs 3, this photovoltaic bypass module 30 to have installing hole 31.This installing hole 31 is usually in flat.The bottom of this box body 10 is provided with the pilot hole 11 aligned with installing hole 31.Obviously, installing hole 31 must be multiple, thus pilot hole 11 is also multiple, and pilot hole 11 and installing hole 31 align between two.One end of this convergent belt is successively connected in this photovoltaic bypass module 30 by the mode of soldering through after pilot hole 11 and corresponding installing hole 31.Like this, by the guiding of pilot hole 11 and installing hole 31, the connection of convergent belt is made to have modularization trend, thus not easily wrongly installed and more for convenience.Meanwhile, by the fixing mode combined with soldering of installing hole 31, make the connection of convergent belt very solid and reliable.
Continue to optimize:
The guide vane end stop 13 of the back-up block 12 supporting this photovoltaic bypass module 30 and the avris being stuck in this photovoltaic bypass module 30 is provided with in this box body 10.Namely; those guide vane end stops 13 and those back-up blocks 12 make the unsettled setting of this photovoltaic bypass module 30; the heating position of this photovoltaic bypass module 30 inside chip is avoided directly to contact with the shell at this box body 10 back side; protect the photovoltaic component back plate be connected with this terminal box, ensure that the long-term reliability of photovoltaic module.
This cable 40 is welded in this photovoltaic bypass module 30 by the mode of medium frequency welding.Certainly, cable 40 is generally 2.More excellent, the outer surface of cable 40 is fixed on this box body 10 by ultrasonic technique.This ensures that, the reliability that cable 40 connects.
