Abstract

The utility model discloses a slot type edge junction box applied in a solar double-glass assembly, which comprises a box cover and a box body. The box cover and the box body are mutually clamped. The box body comprises a cuboid-shaped box chamber with one face provided with an opening. A diode is arranged inside the box chamber along the length direction. The ends of the two base pins of the diode are respectively fixedly connected with a heat radiation metal sheet. Two heat radiation metal sheets are also located inside the box chamber. One box body side surface located on the box chamber opening and another box body side surface opposed to the former side surface respectively extend towards the same direction to form sheet-shaped wing parts. A gap between the two wing parts forms a U-shaped slot where the double-glass assembly can be clamped. A communicating slit is present between the slot and the box chamber. The slit is applied for the leading-out wire of the double-glass assembly to be inserted into the box chamber and further connected with the base pins of the diode. The junction box which has a simple structure and is designed in a way to satisfy the IEC standard prevents water leakage and electric conduction problems. Meanwhile, the junction box is simple and convenient to install and operate.

Above-mentioned purpose of the present utility model realizes by the following technical solutions: a kind of card slot type edge terminal box that is applied to the two glass assemblies of solar energy, the lid and the box body that comprise mutual engaging, described box body has the box chamber of the rectangular build of an opening, be built-in with along its length diode in the box chamber, the termination of two pins of diode is fixedly connected with respectively a slice heat dissipation metal plate, two heat dissipation metal plates also are positioned at described box chamber, it is characterized in that: described box body is in a side that is positioned at box chamber opening and a side relative with this side alar part from sheet to same direction that extend to form respectively, space between two alar parts consists of the U-shaped draw-in groove that can clamp two glass assemblies, have the slit that is communicated with between described draw-in groove and the box chamber, the lead-out wire that this slit is used for two glass assemblies stretches in the box chamber and is connected with the pin of diode.

The utility model adopts the lower end with the terminal box of draw-in groove, and draw-in groove clamps two glass assembly back box chambeies and fills with casting glue, and also seals with silica gel in the draw-in groove, can make like this terminal box very firmly be bonded in the edge of two glass assemblies.

In the utility model, the termination of two pins of described diode is welded with respectively a slice heat dissipation metal plate.

The utility model can be done following improvement: described box body is offered respectively an excessive glue groove in the outside along its length, described box chamber, does not overflow outside the box body when guaranteeing that casting glue is filled the box chamber fully.

Compared with prior art, the utlity model has following remarkable result:

(1) the utility model directly bonds to the assembly edge with present edge terminal box and changes the lower end into the terminal box of card slot type, is stuck in the assembly edge and has also solved the design problem that does not satisfy the IEC standard simultaneously;

(2) the utility model terminal box is also used silica gel and is sealed draw-in groove, can make like this terminal box very firmly be bonded in the edge of two glass assemblies, also is not easy to occur leaking, the conduction problem;

(3) the utility model card slot type terminal box fitting operation is simple, is convenient to install.

Embodiment

A kind of card slot type edge terminal box that be applied to solar energy two glass assemblies extremely shown in Figure 7 such as Fig. 1, the lid 1 and the box body 2 that comprise mutual engaging, box body 2 has three side sealing and closes, the box chamber 3 of the rectangular build of an opening, the face at the opening place in box chamber 3 is the side, be built-in with along its length diode 4 in the box chamber 3, the termination of two pins 41 of diode 4 is fixedly connected with respectively a slice heat dissipation metal plate 5, the mode that specifically is fixedly connected with adopts welding, heat dissipation metal plate 5 can adopt the materials such as copper, two heat dissipation metal plates 5 also are positioned at box chamber 3, box body 2 is in a side that is positioned at box chamber opening and a side relative with this side alar part 7 from sheet to same direction that extend to form respectively, the alar part 7 that namely has two sheets in the lower end of box body 2, space between two alar parts 7 consists of the U-shaped draw-in groove 8 that can clamp two glass assemblies 9, have the slit that is communicated with between draw-in groove 8 and the box chamber 3, the lead-out wire that this slit is used for two glass assemblies 9 stretches in the box chamber 3 and is connected with the pin 41 of diode 4.This terminal box is when clamping two glass assembly 9, draw-in groove 8 clamps, dispel the heat the preferably casting glue filling better with sealing of two glass assembly 9 back box chambeies, the devices such as electronic component in the box chamber 3 are all carried out the casting glue encapsulation, and also seal with silica gel in the draw-in groove 8, so just terminal box firmly is bonded in the edge of two glass assemblies.
