Abstract
The utility model relates to a photovoltaic junction box with an improved structure, comprising a box body and a box cover covering the box body, wherein inside the box body there is provided one or more groups of conductive metal components, the tail portion of the conductive metal components is connected with cables, press blocks are pressed inside the box body, and the press blocks fasten the cables through screws. The photovoltaic junction box with an improved structure fixes the cables inside the box body, thereby increasing the connection reliability of the cables; and in addition, the photovoltaic junction box is provided with metal outer hoops, thereby increasing contact area, reducing contact resistance and reducing heat generation.
Description
(1) technical field
The utility model relates to a kind of photovoltaic terminal box.
(2) background technology
Photovoltaic junction box needs connecting cable that electric energy is exported, and the connection reliability of cable is a very important performance, in the prior art, in use for some time, the phenomenon that cable can occur throwing off.
(3) summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of photovoltaic junction box of architecture advances.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box of architecture advances, include box body and the lid that covers on box body, be provided with a group or more conductiving metal part in the described box body, the afterbody connecting cable of described conductiving metal part, also compress a briquetting in the described box body, and described briquetting is by the screw lock cable.
As preferably, the afterbody of conductiving metal part arranges the cable link of tubulose, the end of described cable connects a metal outer net circle, described metal outer net circle comprises the elastic portion that is surrounded circle by flexure strip, described metal outer net circle inserts and is connected to described cable link, and described flexure strip is stretched in the cable link.
Also compress a briquetting in box body, cable is connected by screw briquetting, and namely cable tightly is fixed in the box body by briquetting, the phenomenon that gets loose can not occur, and has increased connection reliability.Cable connection metal outer net circle, metal outer net circle are that the flexure strip circle becomes, then be inserted in the cable link after, flexure strip opens with the cable link and fully contacts, and has increased contact area, has reduced contact resistance, has reduced heat generation.
The beneficial effects of the utility model are: the utility model is fixed on cable in the box body by arranging of briquetting, has improved the connection reliability of cable, in addition, setting by metal outer net circle, increase contact area, reduced contact resistance, reduced heat generation.
(4) description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, a kind of photovoltaic junction box of architecture advances, include box body 1 and the lid that covers on box body, be provided with a group or more conductiving metal part in the described box body, the afterbody connecting cable 5 of described conductiving metal part, also compress a briquetting 3 in the described box body, and described briquetting 3 is by screw 2 locking cable lines 5.The afterbody of conductiving metal part arranges the cable link of tubulose, the end of described cable connects a metal outer net circle 4, described metal outer net circle 4 comprises the elastic portion that is surrounded circle by flexure strip, described metal outer net circle 4 inserts and is connected to described cable link, and described flexure strip is stretched in the cable link.
Also compress a briquetting 3 in box body, cable 5 connects briquetting 3 by screw 2, and namely cable tightly is fixed in the box body by briquetting 3, the phenomenon that gets loose can not occur, and has increased connection reliability.Cable connection metal outer net circle, metal outer net circle are that the flexure strip circle becomes, then be inserted in the cable link after, flexure strip opens with the cable link and fully contacts, and has increased contact area, has reduced contact resistance, has reduced heat generation.
The utility model is fixed on cable in the box body by arranging of briquetting, has improved the connection reliability of cable, and in addition, the setting by metal outer net circle has increased contact area, has reduced contact resistance, has reduced heat generation.
