Abstract
The utility model relates to the field of solar power components, in particular to a connecting terminal for a photovoltaic junction box. The connecting terminal for the photovoltaic junction box is provided with a connecting terminal body, metal spring pieces and a small spring piece, wherein the small spring piece is arranged at the middle part of the connecting terminal body, the metal spring pieces are divided into a head metal spring piece and a tail metal spring piece, and the head metal spring piece and the tail metal spring piece are respectively arranged at the head and the tail of the connecting terminal body. The utility model has the advantages that when working, the combination of connecting metal spring pieces and conducting wires can be realized only by adopting a most common straight screwdriver, and a complicated special tool adopted nowadays does not need to be adopted, which is quick, simple and convenient. Moreover, diodes are connected by adopting the modes of clamping and connecting, which is quicker, simpler and more convenient than general welding. Furthermore, the cost is also lowered greatly. In addition, the clamping and connecting modes of springs are adopted when the connecting terminal is connected with a lead of a solar component, which is convenient for the operation of installation personnel and saves the time.
Description
Technical field:
The utility model relates to a kind of sun-generated electric power field of components, especially relates to a kind of photovoltaic junction box binding post.
Background technology:
Solar junction box is the important component part of solar-electricity source component, be widely used in the various sun-generated electric power devices, because the binding post in the terminal box is the critical component of the cell module panel busbar of connecting circuit components and parts, therefore just require binding post to have safe and reliable connectivity, the stronger power of holding and the contact pressure of adding arranged, less contact resistance, good corrosion resistance and conductivity.
Along with the continuous development of heliotechnics, the specification requirement of the terminal box specification that component palette is used also improves constantly, and the specification of terminal box develops to little and thin direction, and this just makes the terminal box volume inside more and more littler.Original design adopts contact chip and diode or busbar to be welded, but the time rosin joint appears easily or overlong time causes the too high meeting of temperature that diode is burnt out in welding, particularly when replacing and maintenance maintenance diode, very easily burn out, this is for very inconvenience of operation in the open air, so the utmost point needs a kind of not only handled easily but also is beneficial to the binding post of connection.
Summary of the invention:
The purpose of this utility model be for provide a kind of easy for installation, cost is lower and the photovoltaic junction box binding post that is connected firmly.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of photovoltaic junction box binding post, be provided with binding post body, metal spring sheet and little shell fragment, described little shell fragment is arranged at the middle part of binding post body, described metal spring sheet is divided into head metal spring sheet and afterbody metal spring sheet, and is arranged at the head and the afterbody of binding post body respectively.
Combining of metal spring sheet and lead for convenience, further: described metal spring sheet and little shell fragment all adopt cage construction.
In order to increase cable tension, further: the contact-making surface of described binding post body and head metal spring sheet, afterbody metal spring sheet is provided with tongue.
In order to prevent the displacement of metal spring sheet at the binding post body, further: the two ends of described binding post body respectively offer a buckling groove, and described head metal spring sheet and afterbody metal spring sheet are fixed on the buckling groove.
Further: described buckling groove is the serpentine shape.
The utility model has the advantages that: in work, only need to adopt modal Flathead screwdriver can realize combining of wiring metal spring leaf and lead, need not to adopt as it is the instrument of loaded down with trivial details special use, fast and convenient, and diode adopts snap fit to connect, more fast and convenient than general welding, and cost also reduces greatly.Adopt the mode of spring clamping connection when binding post connects the solar components lead-in wire in addition, make things convenient for the operation of installation personnel, save time.
Description of drawings:
Fig. 1 is a stereogram of the present utility model.
Fig. 2 is the stereogram of Fig. 1 another side.
Among the figure: 1, binding post body; 1-1, tongue; 1-2, buckling groove; 2-1, afterbody metal spring sheet; 2-2, head metal spring sheet; 3, little shell fragment.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of photovoltaic junction box binding post shown in Fig. 1~2, be provided with binding post body 1, metal spring sheet and submissile sheet 3, described submissile sheet 3 is arranged at the middle part of binding post body 1, described metal spring sheet is divided into head metal spring sheet 2-2 and afterbody metal spring sheet 2-1, and be arranged at the head and the afterbody of binding post body 1 respectively, described binding post body 1 and head metal spring sheet 2-2, the contact-making surface of afterbody metal spring sheet 2-1 is provided with tongue 1-1, combining of metal spring sheet and lead for convenience, described metal spring sheet and submissile sheet 3 all adopt cage construction.And in order to prevent the displacement of metal spring sheet at the binding post body, can respectively offer a buckling groove 1-2 at the two ends of binding post body 1, described head metal spring sheet 2-2 and afterbody metal spring sheet 2-1 are fixed on the buckling groove 1-2, and its buckling groove 1-2 can be the serpentine shape.
When connecting, submissile sheet 3 clamping diodes, be easy for installation and removal, it is very convenient when the metal spring sheet connects lead, only need to adopt modal Flathead screwdriver can realize combining of metal spring sheet and lead, need not to adopt as it is the instrument of loaded down with trivial details special use, fast and convenient, and the pulling force of tongue 1-1 design the increase especially lead and terminal.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
