Description

A kind of solar cell frame

Technical field

The utility model 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 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 close-connected solar cell frame of the adjacent 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 solar cell frame, 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 forward surface of described first plugboard and the second plugboard is all shaped with slide block; The another side of described first plugboard and the second plugboard is provided with jagged hangnail;

Gripper shoe is provided with in the opening of described U-board material, cavity is formed between described gripper shoe and U-board material, the one side that described gripper shoe is positioned at cavity is shaped with groove, closely cooperates with corresponding U-board material in the cavity that described first plugboard and the second plugboard insert adjacent U-board material respectively.

Further, multiple reinforcement is all arranged at intervals with in the hollow structure of described first plugboard and described second plugboard.

Further, described slide block is provided with convex lines.

The beneficial effects of the utility model are: arrange gripper shoe in solar cell frame, make 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; First plugboard and the second plugboard forward surface arrange the groove in slide block engage, can insert in U-board material by pilot angle key, make installation more convenient and accurate, and arrange some convex lines in shoe surface, can strengthen the fastness connected; Angle key body is provided with some jagged hangnails, the bonding strength of angle key and U-board material 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.
