Abstract
The invention relates to the field of a solar power supply component, in particular to a connection terminal for a photovoltaic terminal box, which is provided with a connection terminal body, a metal spring leaf and a small tab, wherein the small tab is arranged in the middle of the connection terminal body, and the metal spring leaf comprises a metal spring leaf head and a metal spring leaf tail which are respectively arranged at the head part and the tail part of the connection terminal body. In operation, the terminal metal spring leaf and wires can be combined by simply using the most common slotted screwdriver instead of the complicated special tool in the prior art, thereby realizing fast and convenient operation. Besides, diodes are connected in a clamping mode, thereby ensuring that the connection is faster and more convenient than welding and the cost is greatly lowered. In addition, the connection terminal is connected with solar package leads by means of spring clamping, thereby facilitating the operation of installation personnel and saving time.
Description
Technical field:
The present invention relates to a kind of sun-generated electric power field of components, especially relate 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 objective of the invention is for provide a kind of easy for installation, cost is lower and the photovoltaic junction box binding post that is connected firmly.
The technical solution adopted for the present invention to solve the technical problems 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.
Advantage of the present invention is: 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 invention.
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:
The present invention is further described below in conjunction with drawings and Examples.
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 invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
