Preferably, the crown of said teeth stretches out along the vertical direction on the pressure-bearing portion surface at teeth place.
Preferably, said symmetry folder is provided with a kink.
Preferably, said conducting strip integral body is one-body molded.
The utility model also relates to a kind of battery board bracket, and its characteristics are: comprise described conducting strip, a guide rail and an earthing device, wherein, conducting strip is arranged on the guide rail top, and cell panel is placed on pressure-bearing portion top, and said earthing device is electrically connected with said guide rail.
Preferably, said earthing device comprises that an earth clip, is used for said earth clip is fixed in T type bolt, an outer sawtooth on the guide rail, and wherein, said outer sawtooth is electrically connected with said earth clip.
Preferably, said earth clip comprises a body and a clamping part, and whole clamping part outer surface is an electric conducting material.
Preferably, said earth clip integral body is one-body molded.
Preferably, support also comprises a lead through said clamping part, and the part that said lead contacts with clamping part is a plain conductor.
Preferably, said lead one end ground connection.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: the utility model imports the earth with the static of cell panel effectively, and is safe in utilization, and dependable performance is avoided thunderbolt effectively.

Embodiment
The embodiment of the utility model will describe with reference to accompanying drawing.In Figure of description, element or device with similar structures or function will be used the components identical symbolic representation.Accompanying drawing for the ease of each embodiment of explanation the utility model, is not to carry out the explanation of exhaustive to the utility model just, neither the scope of the utility model be limited.
Fig. 1 and Fig. 2 have disclosed the structural representation of an embodiment of conducting strip under the utility model.In this embodiment, conducting strip comprises a pressure-bearing portion 11, one symmetry folders 12; One portable end 13 is with many to teeth 14, and symmetry folder 12 is arranged on the side of pressure-bearing portion 11, extends to the vertical direction on pressure-bearing subordinate surface; Portable end 13 is arranged on another surface of pressure-bearing portion 11; Upper surface direction to vertical pressure-bearing portion 11 is extended, and every pair of teeth 14 are separately positioned on two surfaces up and down of pressure-bearing portion 11, conduct between each teeth 14.In a preferred embodiment, pressure-bearing portion 11 is provided with four pairs of teeth.The crown of teeth 14 stretches out along the pressure-bearing portion surface direction at vertical teeth place, the battery component aluminium frame and the guide rail oxide layer that make crown to puncture to be placed on it.
In a preferred embodiment; The lower end of symmetry folder 12 is provided with a pair of kink 121; Distance between this kink 121 is pressed from both sides the distance between 12 less than symmetry, like this, and when symmetry folder 12 is placed on the guide rail; Kink 121 has formed bigger elasticity and has added the power of holding, and conducting strip more stably is fixed on the guide rail.Said conducting strip can be one-body molded.
Fig. 3 and Fig. 4 show conducting strip and are placed on the sketch map on the guide rail.Under this state, symmetry folder 12 plays the effect of fixed-conductive film, and conducting strip relies on this two symmetries folder 12 to be installed on the upper surface of guide rail 3.Teeth 14 contact with the upper surface of guide rail 3 fully on the lower surface.Portable end 13 extends upward, and makes things convenient for the user to adjust the installation site of conducting strip on guide rail 3.In the present embodiment, be provided with four pairs of teeth above the pressure-bearing portion 11, the front crown of teeth 14 and the effect of back side crown are the oxide-films that punctures battery component aluminium frame and guide rail surface respectively, thereby make the whole metal parts conducting of mounting system form path.
Guide rail 3 is the assembly material of general solar photovoltaic bracket, is generally processed by shaped steel or angle steel, and there is oxide layer on the surface.In the present embodiment, guide rail 3 is provided with band 31, and band 31 is worked in coordination with symmetry folder kink 121, makes conducting strip add more firmly and is held on the guide rail 3.
