Solar cell frame
Technical field
The present invention relates to a kind of 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.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, the solar cell frame stability of assembling thus is very low, battery component is longer for service time, the more chipping or phenomenon that comes off, therefore, the design carried out solar cell frame is concerning important.
Summary of the invention
The technical problem to be solved in the present invention is: propose one can reduce cost again can enhance mechanical strength, the close-connected solar cell frame of the adjacent frame of solar cell can also be made.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of solar cell frame, and comprise four blocks of U-board materials that angle key is connected with head and the tail, adjacent U-board material is fixedly connected with by angle key; Described angle key comprises 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 two sides of described first plugboard and the second plugboard is equipped with jagged hangnail; Be provided with supporting bracket in the opening of described U-board material, between described supporting bracket and U-board material, form cavity, closely cooperate with corresponding U-board material in the cavity that described first plugboard and the second plugboard insert adjacent U-board material respectively.
Further, the side that described supporting bracket is positioned at cavity is also shaped with that several are protruding.
Further, multiple reinforcement is all arranged at intervals with in the hollow structure of described first plugboard and described second plugboard.
Further, the forward surface of described first plugboard and the second plugboard is shaped with at least one groove in the position near junction.
Beneficial effect of the present invention is: arrange supporting bracket in solar cell frame, makes itself and frame form the framework of a hollow, and angle key connects two adjacent frames by this framework of grafting, easy to operate; Angle key is set to " L " shape structure, adjacent frame can be made vertically to connect, make connection more tight; Angle key body is provided with some jagged hangnails, the side of cavity convexes to form friction with supporting bracket is positioned at, the bonding strength of angle key and frame can be strengthened, not easily landing; Two plugboards of angle key are set to the hollow structure being with reinforcement, can also ensure to be connected mechanical strength and the stability of the solar cell frame after for entirety while alleviating angle key weight and saving production cost; Be formed with at least one groove at the first plugboard of angle key and the forward surface of the second plugboard in the position near junction, can not only concentrated stress be reduced, prevent angle bond fission, can also material be saved, cost-saving.

Embodiment
Embodiment
The solar cell frame of the present embodiment, as shown in Fig. 1 ~ Fig. 5, comprise four blocks of U-board materials 1 that angle key is connected with head and the tail, adjacent U-board material 1 is fixedly connected with by angle key; Described angle key comprises angle key body, and it is affixed and make the cross section of angle key body L-shaped that this angle key body comprises the first plugboard 4 and the second plugboard 5, first plugboard 4 and the second plugboard 5; First plugboard 4 and the second plugboard 5 are hollow structure 9, are all arranged at intervals with multiple reinforcement 7 in this hollow structure 9; The two sides of the first plugboard 4 and the second plugboard 5 is equipped with jagged hangnail 6.
Supporting bracket 2 is provided with in the opening of U-board material 1, cavity 3 is formed between supporting bracket 2 and U-board material 1, side supporting bracket 2 being positioned at cavity 3 is shaped with several projections 8, closely cooperate with corresponding U-board material 1 in the cavity 3 that first plugboard 4 and the second plugboard 5 insert adjacent U-board material 1 respectively, hangnail 6 strengthens Connected degree with protruding 8 phase mutual friction, the not easily landing of angle key.
First plugboard 4, being shaped with groove 9 with the second plugboard 5 one side in opposite directions in the position near junction, can reducing concentrated stress, prevent angle bond fission.
Solar cell frame of the present invention is not limited to the concrete technical scheme described in above-described embodiment, and all employings are equal to replaces the protection range that the technical scheme formed is application claims.
