Description
(1) technical field
The utility model relates to a kind of photovoltaic junction box.
(2) background technology
The photovoltaic terminal box is link important in solar power system, photovoltaic junction box includes the conductive component in box body and box body, and an end of box body connects busbar, the other end connecting cable of box body, electric current is inputted by busbar, then by cable, exported.In prior art, the metallic support of conductive component is all support rack type, namely comprises tube stay spring on support, support, by the tube stay spring, diode is clamped and welds together, and the terminal box of this structure, volume is larger, and electric current runs off more.
(3) summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of conductive component is carried out improved photovoltaic junction box.
The technical scheme in the invention for solving the technical problem is:
a kind of photovoltaic junction box that improves conductive component, comprise box body, be provided with conductive component in box body, described conductive component includes the metallic support that is arranged side by side and is connected to diode between metallic support, the upper end of described metallic support is provided with link, described upper link connects respectively busbar, the lower end that is positioned at the both sides metallic support is respectively arranged with lower link, described lower link connecting cable, described metallic support all is set to sheet, described diode is chip diode, and the upper link surface of described metallic support is provided with the bump of projection.
As preferably, bump is arranged to 4 * 4 matrix forms and is arranged.
As preferably, lower link is provided with the U-shaped card, and described cable is plugged in described U-shaped card, and is crimped on together.
The metallic support of stent-type is arranged to sheet, corresponding diode is transformed to chip diode by original pinned, greatly reduced the volume of terminal box, metallic support in box body can be one time punching molded, carry out again cutting and separating, chip diode directly is welded on above metallic support, has omitted the parts such as tube stay spring.The bump that is the projection that matrix form arranges is set on the upper link surface of metallic support, and busbar is connected on metallic support more reliably, is not easy to pull, and increases the contact area of busbar and metallic support.Cable is plugged in the U-shaped card of both sides metallic support and is crimped on together.
The beneficial effects of the utility model are: the utility model, by the improvement to the conductive component structure, makes the terminal box volume diminish, and the parts of connection reduce, and contact resistance reduces, and busbar connects also more reliable.
(4) description of drawings
Fig. 1 is part blast structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
as shown in Figure 1, a kind of photovoltaic junction box that improves conductive component, comprise box body 1, be provided with conductive component 6 in box body, conductive component includes the metallic support 5 that is arranged side by side and is connected to diode 4 between metallic support, metallic support 5 all is set to sheet, diode 4 is chip diode, the upper end of metallic support is provided with link 2, upper link connects respectively busbar, the upper link surface of metallic support is provided with into the bump 3 of the projection of 4 * 4 matrix forms arrangements, the lower end that is positioned at the both sides metallic support is respectively arranged with lower link 7, lower link 7 connecting cables, lower link is provided with the U-shaped card, cable is plugged in the U-shaped card, and be crimped on together.
The metallic support of stent-type 5 is arranged to sheet, corresponding diode 4 is transformed to chip diode by original pinned, greatly reduced the volume of terminal box, the parts that connect have been reduced, metallic support in box body can be one time punching molded, carry out cutting and separating, chip diode directly is welded on above metallic support again, has omitted the parts such as tube stay spring.Arrange and be the bump 3 that matrix form is arranged on the upper link surface of metallic support, busbar is connected on metallic support more reliably, is not easy to pull, and increases the contact area of busbar and metallic support.Cable is plugged in the U-shaped card of both sides metallic support and is crimped on together.
The utility model, by the improvement to the conductive component structure, makes the terminal box volume diminish, and link reduces, and contact resistance reduces, and busbar connects also more reliable.
