Description
Technical field
The utility model relates to a kind of solar cell frame connection angle key.
Background technology
The rectangular-shaped body that current solar cell frame is mainly assembled into by two long edge frame made of aluminum profiles and two short edge frame made of aluminum profiles, and in the package technique of edge frame made of aluminum profiles, be mainly connected by screw length frame.Namely on a frame, setting an installing hole, a mounting groove is set in another frame, by being inserted in mounting groove through installing hole by screw, connecting adjacent frame.But use screw cross-under can not ensure the compactness of frame junction, on the contrary, screw can not be interted in the place due to solar cell frame buckle cell panel, and therefore use screw to connect the solar cell frame obtained, its stability and firmness are not high.
In the last few years, also started to occur using some plug-in unit to connect length frame.An aluminium section bar plug-in unit for such as square, two ends insert respectively noted glue aluminium section bar long margin frame and aluminium section bar minor face money in, realize connect.But use aluminium profile materials and parts, energy consumption is very large, and cost also increases thereupon.Therefore, use aluminium profile plug-in unit, cost is higher.Meanwhile, if the aluminium section bar plug-in unit of one closed, quality becomes large, and then increases the weight of solar cell frame, affects its mechanical strength.Although also have the design alleviating its weight done for plug-in unit now, be that its internal structure is set to hollow-core construction, outside is the aluminium shape surface of plug-in unit.But the design of complete hollow reduces the intensity of plug-in unit, and then also have impact on stability and the intensity of solar cell frame.
Utility model content
The technical problems to be solved in the utility model is: propose one can reduce cost again can enhance mechanical strength, the frame of solar cell close-connected solar cell frame connection angle key can also be made.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of solar cell frame connection angle key, comprise angle key body, described angle key body comprises the first Plug Division and the second Plug Division, described first Plug Division is vertical affixed with the second Plug Division, described first Plug Division comprises the first plugboard and the second plugboard, and described second Plug Division comprises the 3rd plugboard and the 4th plugboard; The opposite face of the opposite face of described first plugboard and the second plugboard, the 3rd plugboard and the 4th plugboard is provided with sawtooth, and the another side of the another side of described first plugboard and the second plugboard, the 3rd plugboard and the 4th plugboard is all shaped with jagged hangnail.
Further, the junction of described first Plug Division and described second Plug Division is provided with outer chamfering.
Further, the forward surface of described first plugboard and the 3rd plugboard is shaped with at least one groove in the position near junction.
Further, described sawtooth is in the same size.
The beneficial effects of the utility model are: two Plug Divisions arrange two plugboards respectively, can coordinate corresponding frame, make the connection of frame more tight and firm; The opposite face of the opposite face of the first plugboard and the second plugboard, the 3rd plugboard and the 4th plugboard is provided with sawtooth, has both saved cost, has turn improved card and the degree of angle key body and frame; The another side of the another side of the first plugboard and the second plugboard, the 3rd plugboard and the 4th plugboard is all shaped with jagged hangnail, by the resistance of hangnail, can strengthen the bonding strength of angle key and solar cell frame, not easily landing; The outside of the corner of angle key is designed to chamfering structure, not only saves material, also prevent the danger scratched by wedge angle when staff assembles frame.Be shaped with at least one groove at the forward surface of the first plugboard and the 3rd plugboard in the position near junction, can concentrated stress be reduced, prevent angle bond fission.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, solar cell frame connection angle of the present utility model key is described further.
The structural representation of Fig. 1 the utility model embodiment;
Fig. 2 is the cross sectional representation of Fig. 1.
Detailed description of the invention
