Abstract
The utility model relates to a grounding sheet, comprising a main flat plate, wherein the middle part of the main flat plate is provided with a square hole and is provided with a plurality of circular holes near the square hole, a plurality of spines are convexly arranged on the periphery of each circular hole, and the spines are integrally connected with the main flat plate and are respectively higher than the upper and lower surfaces of the main flat plate. When in installation, the grounding sheet is mounted between a photovoltaic module and a crossbeam, and is positioned below a fastener. When the fastener is tightly screwed, the spines on the main flat plate can pierce the surface protective films of the photovoltaic module side frame and the crossbeam simultaneously to be in direct contact with the substrate of the materials, thereby realizing the reliable conductive connection. The grounding sheet has the advantages of concise and fast installation, as well as simple grounding method and structure, does not need to screw a bolt or connect a wire, and improves the installation efficiency.
Description
Technical field
The utility model belongs to the mounting technique field of photovoltaic module, particularly a kind of ground strip.
Background technology
Solar photovoltaic assembly has requirement to ground connection when mounted usually.Because the frame of photovoltaic module mostly adopts the aluminium frame, there are oxide layer or application layer in the surface of aluminium frame, and this oxide layer or application layer are nonconducting, might cause this aluminium frame imperfect earth.So, when the photovoltaic system of grounding requirement is installed, need manage to destroy this oxide layer or application layer, could guarantee the photovoltaic module effective grounding.The solution that has is welding or sets up earth connection, has so both increased mounting hardness, and needing increases extra parts, brings cost pressure, reduces installation effectiveness.
The utility model content
Technical problem to be solved in the utility model is, a kind of simple in structure and ground strip that can reliable ground is provided.
The utility model is achieved in that provides a kind of ground strip, and it comprises main dull and stereotyped, in the middle of main dull and stereotyped, be provided with square hole, also be provided with some circular holes near square hole, convex with some spines at the periphery of each circular hole, spine is connected with main dull and stereotyped one, and exceeds main dull and stereotyped upper and lower surface respectively.
Further, circular hole is symmetrically distributed on the main flat board.
Further, along main dull and stereotyped length direction, between square hole and main dull and stereotyped outer ledge, be respectively arranged with two row's circular holes.
Further, along main sheet width direction, between square hole and main dull and stereotyped outer ledge, be respectively arranged with two row's circular holes.
Further, circular hole quantity is eight.
Further, ground strip is made by metal conductive materials.
Compared with prior art, ground strip of the present utility model, it comprises main dull and stereotyped, is provided with square hole main in the middle of dull and stereotyped, also is provided with some circular holes near square hole, convexes with some spines at the periphery of each circular hole, spine exceeds main dull and stereotyped upper and lower surface respectively.During installation, the utility model is placed between photovoltaic module and the crossbeam, and is arranged on the below of securing member.When securing member screwed, the spine on the main flat board can puncture the surface protection film of photovoltaic component frame and crossbeam simultaneously, directly contacted with the ground of material, realized that ground connection connects reliably.Earthing mode of the present utility model is simple in structure, need not to increase bolt, nut, improves installation effectiveness.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model one preferred embodiment.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to shown in Figure 1, the schematic perspective view of ground strip embodiment of the present utility model.Ground strip 1 of the present utility model comprises main flat board 2, square hole 3, some circular holes 4 and some spines 5.
In the middle of main dull and stereotyped 2, be provided with square hole 3, be convenient to securing member and therefrom pass.Also be provided with some circular holes 4 near square hole 3, convex with some spines 5 at the periphery of each circular hole 4, spine 5 is connected with main dull and stereotyped 2 one, and exceeds respectively and lead dull and stereotyped 2 upper surface 21 and lower surface 22.
In the present embodiment, the quantity of circular hole 4 is eight, and is symmetrically distributed on main dull and stereotyped 2.Along main dull and stereotyped 2 length directions, between square hole 3 and main dull and stereotyped 2 outer ledges, be respectively arranged with two row's circular holes 4, four of every rows, totally eight.These eight circular holes 4 also meet main dull and stereotyped 2 Widths in edge and be respectively arranged with the arrangement requirements of two row's circular holes 4 between square hole 3 and main dull and stereotyped 2 outer ledges.That is to say that eight circular holes 4 both were divided into four rows along main dull and stereotyped 2 length direction symmetry, two of every rows also are divided into four rows, two of every rows along main dull and stereotyped 2 Width symmetry.Such arrangement mode has increased the area of arranging of spine 5, has enlarged the scope of application of the present utility model.
During use, ground strip 1 of the present utility model is installed between photovoltaic module and the crossbeam, and is positioned at the below of securing member.When securing member screwed, the spine 5 on the main flat board 2 can puncture the surface protection film of photovoltaic component frame and crossbeam simultaneously, directly contacts with the ground of material, realize that conduction connects reliably, and the ground connection effect was poor unlike common use earth connection.The utility model is installed fast succinct, and earthing mode is simple in structure, need not to twist bolt or wiring, improves installation effectiveness.
The ground connection that forms conduction for the crossbeam that is in contact with it connects, and in the present embodiment, ground strip 1 is made by metal conductive materials.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
