Abstract
The utility model relates to an improving diode connection structure photovoltaic junction box which comprises a box body. A plurality of metal supports are in order arranged inside the box body, wherein diodes are connected among the metal supports and slots are respectively disposed on the metal supports. Pins of the diodes are clamped into the slots and are connected through a tin welding connection structure. The improving diode connection structure photovoltaic junction box not only increases clamping power and prevents looseness of the diodes, but also enlarges contact areas and reduces contact resistance by improving connection structure of the diodes.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box.
Background technology
Diode is connected between the metallic support, and its syndeton and mode also have very big influence to photovoltaic junction box, in the prior art; Need diode be inserted and be installed in the jack of metallic support; But, because chucking power is not enough, diode is prone to loose; And particularly repeatedly the plug after, clamping force a little less than.In addition, mostly be to contact or the line contact between the pin of diode and the metallic support, contact resistance is bigger.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of chucking power bigger, and increases the photovoltaic junction box of the improvement diode syndeton of contact area.
The technical scheme that the utility model solves its technical problem is:
A kind of photovoltaic junction box that improves the diode syndeton; Comprise box body; Be arranged in order in the described box body and be provided with the number of metal support, be connected with diode between the described metallic support, be respectively arranged with draw-in groove on the described metallic support; Described diode pin snap in the draw-in groove, and connect through the soldering syndeton.
As preferably, be provided with plastic feet in the described box body, snapped in the triangle jump ring on the described plastic feet, the both sides of described triangle jump ring are respectively arranged with flank, and the middle part of described triangle jump ring is set to arc.
Draw-in groove is set on metallic support, and the pin of diode snaps in the draw-in groove and through the soldering syndeton and connects, and like this, diode not only is connected firmly, and has increased the pin of diode and the contact area between the metallic support, has reduced contact resistance.Adopt the flank structure in triangle jump ring both sides, be bumped in the plastic feet after the product assembling, increased plastic feet to the power of holding tightly that the triangle jump ring produces, be difficult for skidding off when making things convenient for the folding of triangle jump ring folder busbar, arcuate structure can be submitted the clamping force to busbar to.
The beneficial effect of the utility model is: the utility model has not only increased chucking power and has prevented that diode from getting loose, and increased contact area through improving the syndeton of diode, has reduced contact resistance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Of Fig. 1; A kind of photovoltaic junction box that improves the diode syndeton comprises box body 4, is arranged in order in the box body to be provided with number of metal support 5; Be connected with diode 1 between the metallic support 5; Be respectively arranged with draw-in groove 3 on the metallic support, the pin 2 of diode snaps in the draw-in groove 3, and connects through the soldering syndeton.In box body, be provided with plastic feet 7, snapped in triangle jump ring 6 on the plastic feet 7, the both sides of triangle jump ring are respectively arranged with flank 8, and the middle part of triangle jump ring is set to arc.
Draw-in groove 3 is set on metallic support, and the pin 2 of diode snaps in the draw-in groove and through the soldering syndeton and connects, and like this, diode not only is connected firmly, and has increased the pin of diode and the contact area between the metallic support, has reduced contact resistance.Adopt flank 8 structures in triangle jump ring 6 both sides; Be bumped in the plastic feet 7 after the product assembling; Increased plastic feet to the power of holding tightly that the triangle jump ring produces, be difficult for skidding off when making things convenient for the folding of triangle jump ring folder busbar, arcuate structure can be submitted the clamping force to busbar to.
The utility model has not only increased chucking power and has prevented that diode from getting loose, and increased contact area through improving the syndeton of diode, has reduced contact resistance.
