Abstract
The utility model relates to a junction box structure of a solar photovoltaic assembly, comprising a body and characterized in that each side of the bottom edge of the body is provided with at least more than one cylindrical protrusion of which the diameter and the height are 1-6mm. The utility model has the advantages that under the premise of enough applying the same silica gel, though the addition of the protrusions and the grit finish, the contact areas between the silica gel and the junction box and between the silica gel and the photovoltaic assembly are increased so as to achieve the larger sealing bonding strength.
Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly terminal box, relates in particular to the polycrystalline substance of this terminal box.
Background technology
As everyone knows, terminal box being installed is important link in solar photovoltaic assembly manufacturing process.Have only terminal box correctly has been installed effectively, one-piece assemblies could be connected to another part assembly, and then the mode of assembly module by series, parallel connected into a power generation applications system.
Since in the use after assembly is installed be glass upwards, backboard faces down tilted-puttedly, has only enough silica gel could produce enough bonding strengths to overcome terminal box and the silica gel peeling force because of the generation of conducting oneself with dignity.And there is open defect in the terminal box of using in the market.
At present the assembly manufacturing is generally used the smooth terminal box in bottom surface, is to install manually and install what generally use, and this just exists very big hidden danger of quality and defective.Because do not have special frock and instrument, be difficult to guarantee whether the silica gel use amount is sufficient, even the silica gel amount is enough, also be difficult to avoid because of the inhomogeneous risk that silica gel is pushed away of exerting oneself, and then cause the minimizing of remaining silica gel amount, terminal box and backboard to reduce until the consequence that comes off because of bond area reduces bonding strength.
Summary of the invention
The utility model technical issues that need to address have provided a kind of solar photovoltaic assembly junction box structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: body; Every side setting at the lower surface edge of body is more than one at least, diameter and highly be the cylindrical protrusions body of 1-6mm.
Compared with prior art, the beneficial effects of the utility model are: under the prerequisite of smearing identical enough silica gel amounts, handle by increasing raised body and frosting technology, can increase silica gel and terminal box, silica gel and photovoltaic module backboard contact area, to reach the purpose of bigger seal bond intensity.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: body 1; Every side setting at the lower surface edge of body 1 is more than one at least, diameter and highly be the cylindrical protrusions body 2 of 1-6mm;
Described raised body 2 is 8 altogether, and every side is 2;
The structure after frosting technology is handled is all adopted on the surface of described body 1 bottom and raised body 2.
Make mould by improving terminal box, make finish after, form 8 diameters and highly be the cylindrical protrusions of 1-6mm at 8 diverse locations of bottom edge.Use such terminal box under the prerequisite of smearing same silica gel amount, only need applying light to the terminal box can not vertical moving (salient point contacts with backboard), so just can prevent to greatest extent that silica gel is extruded away, just can guarantee to have enough silica gel to produce enough adhesive strengths; (2) comprise that the salient point bottom surface handles with frosting technology around terminal box bottom surface and the salient point, can further increase the contact area of terminal box and silica gel like this, further increase adhesive strength.The purpose of above corrective measure is further to strengthen terminal box and backboard bonding strength, guarantees that terminal box does not come off, keeps the normal operation of electricity generation system in the shelf-life.
Claims (3)
