Abstract
The utility model relates to a photovoltaic junction box. The junction box comprises a bottom box and a box cover which is buckled on the bottom box. A support of a metal is successively provided with two jacks at a vertical direction. One side of each jack is downwardly extended so as to form a first clamping piece respectively. Two lateral sides of the support are provided with side edges which are extended upwardly respectively. Side edges are provided with two gaps respectively. A gap position corresponds with a jack position. A lower spring is arranged below the support. Two sides of the lower spring are provided with second clamping pieces respectively. The first clamping pieces and the second clamping pieces can be mutually clamped. According to the utility model, through improving the structure of the metal support, the structure is simple and reliable; manufacturing is convenient and cost is saved.
Description
Technical field
The utility model relates to a kind of photovoltaic terminal box.
Background technology
Photovoltaic junction box is between the solar cell array of solar module formation and the connector between the solar charging controller for electric consumption.Generally comprise interior metallic support of box body and box body and the diode on the metallic support, in the prior art, metallic support includes support and last spring, as shown in Figure 1, cooperation by last spring and support clamps diode, last spring is arranged on the support top, and the pin of diode passes spring and is clamped in the support, and last spring and support branch are arranged and comparatively bother.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of photovoltaic junction box of going up spring and the setting of support integral type.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box, comprise end box and the lid that is fastened on the end box, be provided with metallic support in the box of the described end, described metallic support comprises support, described support is disposed with two jacks in a longitudinal direction, one side of described jack is extended with first intermediate plate respectively downwards, the both lateral sides of described support is respectively arranged with upwardly extending side, be respectively arranged with two breach on the described side, and the corresponding described jack position of described gap position, the below of described support is provided with down spring, and the described both sides of spring down are respectively arranged with second intermediate plate, and described first intermediate plate and second intermediate plate can clamp mutually.
As preferably, first intermediate plate and the second intermediate plate camber, the bottom of described breach also is an arc.
As preferably, metallic support is arranged on the plastic feet, and described plastic feet is assemblied in the box of the described end.
As preferably, the edge of end box is provided with reinforcement.
Support and last spring integral type are provided with, promptly are provided with side in the both sides of support, breach is set on the side, then the pin of diode is introduced from indentation, there, is inserted in the jack, and first intermediate plate of jack one side and second intermediate plate of following spring clamp diode.Following spring structure is comparatively simple, just is provided with for clamping diode.First intermediate plate and second intermediate plate all are arranged to arc, and the bottom of breach also is set to arc, is in order to cooperate the cylindrical setting of pin, can to increase contact area like this, reducing contact resistance.Metallic support is installed in earlier on the plastic feet, refills to allocate in the end box, and than the metallic support that directly is assembled in the end box, its metallic support size is less, can save cost.The edge of end box also is provided with reinforcement, strengthens the structural strength of end box.
The beneficial effects of the utility model are: the utility model passes through the improvement to the structure of metallic support, makes it simple in structure, and is easily manufactured, also saved cost.
