Abstract

The utility model discloses a photovoltaic junction box. The photovoltaic junction box comprises a box body and a connecting piece, wherein the connecting piece is arranged in the box body; a busbar is arranged on the box body and extends to and is electrically connected with a photovoltaic component; and a wiring terminal is arranged on the connecting piece and electrically connected with the busbar in a clamping and welding combined manner. The photovoltaic junction box can solve the problems of heating and combustion, which are caused by poor connection between the photovoltaic component and the junction box.

Description

A kind of photovoltaic junction box
Technical field
The utility model relates to the photovoltaic power generation technology field, relates in particular to a kind of photovoltaic junction box.
Background technology
At present, the electric connecting mode of the binding post of photovoltaic junction box and component bus bar is mainly the mechanical snap mode.But, adopt the mechanical snap mode to be easy to occur the situation of virtual connection, reliability is low.In the actual motion of photovoltaic module, the electric current of assembly is very high, and generally more than 8A, if having virtual connection between the binding post of the output lead of photovoltaic module and terminal box, the phenomenon of the burning of will generating heat causes connecing the box body distortion even burns.
The utility model content
The utility model proposes a kind of photovoltaic junction box, can solve the heating combustion problem that photovoltaic module and terminal box bad connection cause.
The photovoltaic junction box that the utility model embodiment provides comprises box body and connector; Described connector is arranged on the inside of described box body; Also be provided with busbar on the described box body, described busbar extends to photovoltaic module, and is electrically connected with described photovoltaic module; Described connector is provided with binding post, is electrically connected with the mode that welding combines by clamping between described binding post and the described busbar.
In a preferred implementation, described binding post is provided with rotation and presses fastener; Press fastener that described busbar is fixed on the described binding post by described rotation.
In another preferred implementation, the termination of described busbar is provided with jump ring, can holding on described binding post.
The photovoltaic junction box that the utility model embodiment provides, adopt the electric connection mode of the double insurance that welding combines with clamping between the busbar of its binding post and photovoltaic module, the reliability height, can avoid occurring between the output lead of photovoltaic module and the terminal box binding post phenomenon of virtual connection effectively, can solve the heating combustion problem that photovoltaic module and terminal box bad connection cause well, the useful life that can also improve terminal box.
Description of drawings
Fig. 1 is the structural representation of the photovoltaic junction box that provides of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Referring to Fig. 1, be the structural representation of the photovoltaic junction box that provides of the utility model embodiment.
The photovoltaic junction box that present embodiment provides comprises box body 1 and connector 2; Connector 2 is arranged on the inside of box body 1; Also be provided with busbar on the box body 1, busbar extends to photovoltaic module, and is electrically connected with described photovoltaic module; Connector 2 is provided with binding post, is electrically connected with the mode that welding combines by clamping between binding post and the busbar.
Preferably, the welding manner between described binding post and the described busbar is the tin brazing mode.
As shown in Figure 1, be provided with a plurality of connectors in the box body 1; Be provided with diode 3 between two adjacent connectors.
More specifically, box body 1 is provided with installing hole; Busbar is drawn from the bottom of photovoltaic module, passes described installing hole, is connected on the binding post of terminal box.
In a preferred implementation, the binding post of terminal box is provided with rotation and presses fastener; Press fastener that busbar is fixed on the binding post by rotation.
In another preferred implementation, the termination of busbar is provided with jump ring, can holding on binding post.
The photovoltaic junction box that the utility model embodiment provides, adopt the electric connection mode of the double insurance that welding combines with clamping between the busbar of its binding post and photovoltaic module, the reliability height, can avoid the output lead of photovoltaic module and the phenomenon of the appearance virtual connection between the terminal box binding post effectively, can solve the heating combustion problem that photovoltaic module and terminal box bad connection cause well, the useful life that can also improve terminal box.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
