Abstract
The utility model relates to a kind of angle key for connecting solar cell frame, comprise angle key body, described angle key body comprises the first plugboard and the second plugboard, described first plugboard and the second plugboard are hollow structure, first plugboard and the second plugboard affixed and make the cross section of described angle key body L-shaped, the forward surface of described first plugboard and the second plugboard is equipped with jagged hangnail.This solar cell frame angle key is easy for installation, and can be cost-saving, improves connection compactness and the mechanical strength of frame.
Description
Technical field
The utility model relates to a kind of angle key for connecting solar cell frame.
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 packaging technology 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 close-connected angle key for connecting solar cell frame of the frame of solar cell can also be made.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of angle key for connecting solar cell frame, comprise angle key body, described angle key body comprises the first plugboard and the second plugboard, described first plugboard and the second plugboard are hollow structure, first plugboard and the second plugboard affixed and make the cross section of described angle key body L-shaped, the forward surface of described first plugboard and the second plugboard is equipped with jagged hangnail.
Further, multiple reinforcement is all arranged at intervals with in the hollow structure of described first plugboard and the second plugboard.
Further, described first plugboard and the second plugboard are shaped with chamfering respectively away from the side of affixed point.
Further, the forward surface of described first plugboard and the second plugboard is shaped with at least one groove in the position near junction.
The beneficial effects of the utility model are: the forward surface of the first plugboard and the second plugboard is equipped with jagged hangnail, by the frictional force of hangnail, can strengthen the bonding strength of angle key and solar cell frame, not easily landing; First plugboard and the second plugboard are shaped with chamfering respectively away from the side of affixed point, facilitate angle key and frame to carry out grafting.Two plugboards are arranged the hollow structure of band reinforcement, the intensity of angle key can also be ensured while alleviating angle key weight and saving production cost.The forward surface of the first plugboard and the second plugboard is formed with at least one groove in the position near junction, can not only reduce concentrated stress, prevent angle bond fission, can also save material, cost-saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the angle key for connecting solar cell frame of the present utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cross sectional representation of Fig. 1.
Embodiment
Embodiment
The angle key for connecting solar cell frame of the present embodiment, as shown in Figure 1 and Figure 2, comprises angle key body, and the length that this angle key body comprises the first plugboard 1 and the second plugboard 2, first plugboard 1 and the second plugboard 2 is 30-50mm, and thickness is 4-6mm; First plugboard 1 and the affixed cross section of angle key body that makes of the second plugboard 2 L-shaped.
First plugboard 1 and the second plugboard 2 are all set to hollow structure 5, are all arranged at intervals with multiple reinforcement 7 in hollow structure 5, to improve mechanical strength and the stability of angle key body.
The forward surface of the first plugboard 1 and the second plugboard 2 is all shaped with jagged hangnail 4, and hangnail 4 all tilts to the junction of the first plugboard 1 and the second plugboard 2.
First plugboard 1 and the second plugboard 2 are shaped with chamfering 3 respectively away from the side of affixed point.
First plugboard 1 is being shaped with groove 6 with the second plugboard 2 one side in opposite directions near the position of junction.
Angle key for connecting solar cell frame of the present utility model is not limited to the various embodiments described above, and all employings are equal to replaces the technical scheme formed and all drop on the protection range that the utility model requires.
