Abstract
The utility model discloses an aluminum section used for a solar cell frame. The section of the aluminum section used for the solar cell frame is of an L shape. An upper end of a vertical edge of the L-shaped aluminum section is provided with a clamping port. An upper clamping face and a lower clamping face arranged from inside out in the clamping port are inclined back to back. The upper clamping face narrows downward and a clamping connection port of the upper clamping face is a knuckle. The lower clamping face protrudes upward slightly. Positioning grooves are arranged in the upper clamping face and/or the lower clamping face. A clamping connection port of the lower clamping face is a knuckle. The length of the upper clamping face is shorter than the length of the lower clamping face. A lower end of the lower clamping face is provided with a transition support connected with a lower support board integrally. By adopting the above scheme, the lower clamping face is enlarged and the support of the lower clamping face is strengthened. Point contact of the lower clamping face and an assembly in traditional technique is changed to be surface contact, so that a support area of the assembly is enlarged, the support force of the assembly is increased and the anti-pressure capability of the assembly is improved substantially. Therefore, the aluminum section used for the solar cell frame can meet use requirements for the assembly in areas with heavy snowfall.
Description
Technical field
The utility model relates to a kind of structure of aluminium section bar, is specifically related to a kind of aluminium section bar for the solar cell frame.
Background technology
One necessary group frame operation is arranged in the production of crystal silicon solar battery component, the aluminium section bar that is about to have ad hoc structure is cut into frame according to certain group angle mode, evenly inject silica gel in the groove structure that four frames are corresponding, insert respectively in the frame groove of four frames on assembly four limits, by extruding, assembly four limits and frame are bonded together by silica gel, reach the effect of fixing and black box, form module frame.At present, aluminium section bar commonly used has cross section structure form as shown in Figure 1, large, outer little in the mould shape groove of its clip assembly, near inclination, card interface lower boundary round edge is large relatively for upper and lower two card access surfaces, because its mould shape groove is longer, its support force to assembly is better, but during groove injecting glue (especially manual injecting glue), it is inhomogeneous injecting glue often to occur, thereby seal not in placely around causing behind the assembly group frame, have a strong impact on weatherability and the useful life of assembly; And lower frame is some contact to the support of assembly substantially, fragile assembly in transportation and under the impact of external environment.Aluminium section bar commonly used also has cross section structure form as shown in Figure 2, the inside and outside in the same size of its mould shape groove, upper and lower two card access surfaces are parallel, the lower boundary at card interface place is very little fillet, the contact area of this aluminium section bar and assembly is less, support force is relatively poor, is not suitable for the snowfall larger area and uses; During groove injecting glue (especially manual injecting glue), it is inhomogeneous injecting glue often to occur, thereby seals not in placely around causing behind the assembly group frame, has a strong impact on weatherability and the useful life of assembly; And lower card access surface is some contact to the support of assembly substantially, fragile assembly in transportation and under the impact of external environment.In a word, there is certain familiar lacunas in the structure of the aluminium section bar of existing battery component group frame, sealing property or the support degree of assembly have been reduced, along with the raising to the battery component performance requirement, performance requirement to group frame aluminium section bar is also more and more higher, both require its support force large behind the group frame, required again its good sealing effect.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provides a kind of support force large, and good sealing effect is for the aluminium section bar of solar cell frame.
For achieving the above object, the technical solution of the utility model is a kind of aluminium section bar for the solar cell frame of design, the cross section of described section bar is L-shaped, it is characterized in that, upper end at the stile of described L-shaped section is provided with bayonet socket, described bayonet socket is gone up from inside to outside, lower two card access surfaces tilt relatively dorsad, described upper card access surface is tightened up downwards, the card interface place of described upper card access surface is knuckle, the described lower card access surface dimpling that makes progress, card access surface and/or lower card access surface are provided with detent on described, the card interface place of described lower card access surface is knuckle, described upper card access surface is shorter than lower card access surface, is provided with an excessive support that is connected as a single entity with lower supporting plate in described lower card access surface lower end.
Wherein preferred technical scheme is that the both sides of described aluminium section bar lower supporting plate and L-shaped section and lower card access surface form the groove of square-section.
Further preferred technical scheme is that described lower supporting plate is provided with reinforcement in groove inwall one side.
Further preferred technical scheme also has, and the bottom surface of described L-shaped section is corrugated surface.
Advantage of the present utility model and beneficial effect are: adopted such scheme owing to should be used for the aluminium section bar of solar cell frame, it has increased time card access surface, and lower card access surface increased support, contacted by the point in the conventional art between lower card access surface and the assembly and become the face contact, increased the Area of bearing to assembly, strengthen the support force to assembly, greatly promoted the anti-pressure ability of assembly, can satisfy the use of the assembly of snowfall larger area.Expansion type design in section bar cross section mould shape groove adopts is convenient to play glue, and has greatly been promoted the sealing property of assembly behind the injecting glue.Make its use that is more suitable for snowfall, rainfall larger area, and not fragile assembly in transportation and in the abominable external environment.
