Then the applicant have developed a kind of photovoltaic diode, the outside of photovoltaic combiner box and photovoltaic module can be placed in, including packaging body, packaging body includes housing and the diode chip for backlight unit being placed in housing, two terminals that the negative electrode with diode chip for backlight unit is corresponding with anode are drawn at the two ends of packaging body respectively, the link buckle secure fit that terminals are corresponding with photovoltaic combiner box and photovoltaic module, the bottom of housing is fixedly installed heat dissipation base. Owing to the link on photovoltaic combiner box and photovoltaic module is more, this spline structure is when mounted, it is necessary to install one by one, too time-consuming, and needs once break down to investigate maintenance one by one, affects overhaul efficiency.
Utility model content
Based on the problems referred to above, this utility model purpose is in that to provide a kind of photovoltaic counnter attack diode, it is possible to realizes Fast Installation and malfunction elimination, has less volume.
For problem above, provide following technical scheme: a kind of photovoltaic counnter attack diode, it is characterized in that: include packaging body, packaging body includes housing and at least two diode chip for backlight unit being placed in housing, the anode of each diode chip for backlight unit is linked into an integrated entity by cross structure, cross structure is provided with anode connection end, anode connection end is placed in above cross structure and both are by elastic bend part realization elasticity connection, also including the Anode connection drawn from the side of packaging body, Anode connection is connected to anode connection end; The negative electrode of each diode chip for backlight unit forms independent cathode connection end respectively, also include the cathodic connection drawn from the side of packaging body, cathodic connection is connected to each cathode connection end, the end of described Anode connection and cathodic connection arranges and fixes, with photovoltaic combiner box and photovoltaic module buckle, the snap component being connected, and the bottom of housing is fixedly installed heat dissipation base.
This utility model is further arranged to, and the number of described diode chip for backlight unit is two.
This utility model is further arranged to, and described snap component is fastener corresponding with Anode connection and cathodic connection respectively and card retaining ring, and fastener is connected with card retaining ring buckle secure fit.
This utility model is further arranged to, and the anode connection end of described cross structure is formed by integrated punching.
The beneficial effects of the utility model: enter the structure having more by one and arrange, can arrange in packaging body and organize diode chip for backlight unit more, when mounted, grafting buckle can be rapidly performed by install, when a failure occurs, can pass through to pull out Anode connection and realize quick malfunction elimination, to realize the replacing of counnter attack diode further.
