Abstract
A plug-in type junction box comprises an upper cover and a lower box, the lower box is covered with the upper cover, and a seal ring is arranged between the upper cover and the lower box. A supporting body of a first conducting strip, a spring distracting part having a certain distance with the supporting body, parallel with the supporting body and used for distracting an bow spring preforming and a perforation used for penetrating through a second conducting strip are arranged in the lower box, wherein, the cross section of the spring distracting part is increased from top to bottom gradually. The supporting body is covered with the first conducting strip, the bow spring preforming is arranged on the inner side of the upper cover and corresponds to the position of the spring distracting part; the second conducting strip is contacted with the first conducting strip via the perforation, the bow spring preforming is splayed under the role of the spring distracting part to support the first conducting strip and the second conducting strip tightly. The plug-in type junction box of the utility model has the advantages of convenient assembly and maintenance.
Description
Technical field
The utility model relates to a kind of plug-in type terminal box, especially a kind of assembling and plug-in type solar junction box easy to maintenance.
Background technology
Existing terminal box, especially solar junction box, generally comprise loam cake, following box, described loam cake covers on the described following box, is provided with sealing ring between described loam cake and the described following box, is provided with electric elements in the box down described, electric elements one end is connected with solar panels, and the other end is an electric energy output end.At present, described electric elements (being generally diode in series) and the solar panels end that joins normally adopts welding manner, this employing welding manner, there are the following problems, the one, very inconvenient during welding because the welding space is little, and ferrochrome is easy to damage is scalded in following box bottom surface; The 2nd, adopt welding manner, in case the welding position breaks down, its maintenance is also very inconvenient, it needs the professional, utilizes ferrochrome just can keep in repair, otherwise the general operation personnel can't keep in repair.
The utility model content
In order to address the above problem, the utility model provides a kind of assembling and plug-in type terminal box easy to maintenance to society.
The technical solution of the utility model is: design a kind of plug-in type terminal box, comprise loam cake, following box, described loam cake covers on the described box down, be provided with sealing ring between described loam cake and the described following box, be provided with the supporter of first conducting strip in the described box down, be parallel to described supporter and be provided with the shell fragment that is used to strut the semielliptic spring compressing tablet and strut parts with described supporter is separated by a distance, the cross section that described shell fragment struts parts increases from the top down gradually, and the perforation that is used to pass second conducting strip, described first conducting strip covers on the supporter, described semielliptic spring compressing tablet is arranged on the described loam cake medial surface, and with described shell fragment to strut position component corresponding, described second conducting strip contacts with described first conducting strip by perforation, described semielliptic spring compressing tablet struts under the parts effect at described shell fragment and opens, and described first conducting strip and second conducting strip are held out against.
As to improvement of the present utility model, described second conducting strip and the contacted position of first conducting strip are between described first conducting strip and described semielliptic spring compressing tablet.
As to improvement of the present utility model, described first conducting strip and the contacted position of second conducting strip are between described second conducting strip and described spring pressuring plate.
As to improvement of the present utility model, described semielliptic spring compressing tablet is fixedlyed connected with described loam cake by screw.
As to improvement of the present utility model, described supporter is identical with the shape of conducting strip homonymy away from the side that described shell fragment struts parts.
As to improvement of the present utility model, described sealing ring is made with rubber.
As to improvement of the present utility model, described sealing ring is made with silica gel.
The utility model is owing to adopt the mode of semielliptic spring compressing tablet compressing contact to replace original welding manner, like this, not only when producing, have advantage easy to assembly, and when maintenance, do not need the professional to use professional tool just can keep in repair yet, use maintenance to become very convenient yet.
