Description
Technical field
The utility model relates to a kind of photovoltaic junction box.
Background technology
Connected by cable between photovoltaic junction box, in prior art, both positive and negative polarity cable connection end is all that mutual anaemia is arranged usually, and namely box body right angle is drawn relatively, and like this, in some occasion, cable will necessarily bend, and causes certain bending loss.In addition, diode does not have location structure, comparatively random during installation.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of photovoltaic junction box improving to adapt to different occasion to cable outlet method.
The technical scheme in the invention for solving the technical problem is:
A kind of photovoltaic junction box of improvement, comprise box body and be arranged on the photovoltaic module in box body, it is characterized in that: the left and right sides of described box body tilts respectively and extendedly has the first cable connection end and the second cable connection end, the first described cable connection end and the second cable connection end form obtuse angle mutually, the metallic support that described photovoltaic module comprises sheet and the chip diode be connected between metallic support, described metallic support is respectively arranged with pin groove, the pin of described chip diode respectively correspondence to be arranged in pin groove and to be welded on metallic support.
As preferably, metallic support is also respectively arranged with the groove of coupling chip diode body, described chip diode body is corresponding to be respectively arranged in described groove.
As preferably, the angle of the first cable connection end and the second cable connection end is 100 ° ~ 120 °.
As preferably, box body comprises at the bottom of box and lid is located at upper box cover at the bottom of box, and described lid is also covered with the second lid, and busbar connecting hole is offered in the upper end of metallic support, and at the bottom of box, corresponding busbar connecting hole position offers busbar introduction hole.
As preferably, the lower end being positioned at the metallic support of both sides tilts respectively and extendedly has cable end, and cable end comprises opening up U-shaped intermediate plate, offers the crimping hole of corresponding U-shaped intermediate plate at the bottom of described box respectively.
The first cable connection end and the second cable connection end is obliquely installed respectively in the left and right sides of box body, angle is formed between first cable connection end and the second cable connection end, angle is obtuse angle, compared to generally arranged in parallel in prior art, like this in some occasions, cable can be avoided to bend, cause bending loss.
Metallic support arranges pin groove, the pin correspondence of chip diode is arranged on pin groove, metallic support also arranges groove, the body of chip diode also respectively correspondence be arranged in groove, the setting of pin groove and groove not only can position diode, unified position, and also reduce the whole height of photovoltaic module.
Busbar is introduced from the busbar introduction hole at the bottom of box, and the busbar connecting hole entered on metallic support is welded to connect.Cable puts into U-shaped intermediate plate, then by crimping hole operation by U-shaped intermediate plate clamping cables line.
The beneficial effects of the utility model are: the utility model is by changing the outlet method of cable, in some occasions, cable can not carry out bending connection, decreases bending loss, can be positioned diode by arranging of groove, facilitate installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 of improvement, the photovoltaic module comprising box body 2 and be arranged in box body, the left and right sides of box body tilts respectively and extendedly has the first cable connection end 13 and the second cable connection end 3, the first described cable connection end and the second cable connection end form obtuse angle mutually, the metallic support 5 that described photovoltaic module comprises sheet and the chip diode 12 be connected between metallic support, described metallic support is respectively arranged with pin groove 10, the pin of described chip diode respectively correspondence to be arranged in pin groove and to be welded on metallic support.Metallic support is also respectively arranged with the groove 11 of coupling chip diode body, described chip diode body is corresponding to be respectively arranged in described groove.The angle of the first cable connection end and the second cable connection end is 100 ° ~ 120 °.Box body to comprise at the bottom of box 7 and lid be located at upper box cover at the bottom of box, described lid is also covered with the second lid 1, busbar connecting hole 4 is offered in the upper end of metallic support, and at the bottom of box, corresponding busbar connecting hole position offers busbar introduction hole 6.The lower end being positioned at the metallic support of both sides tilts respectively and extendedly has cable end, and cable end comprises opening up U-shaped intermediate plate 8, offers the crimping hole 9 of corresponding U-shaped intermediate plate at the bottom of described box respectively.
The first cable connection end 13 and the second cable connection end 3 is obliquely installed respectively in the left and right sides of box body, angle is formed between first cable connection end and the second cable connection end, angle is obtuse angle, compared to generally arranged in parallel in prior art, like this in some occasions, cable can be avoided to bend, cause bending loss.
Metallic support arranges pin groove 10, the pin correspondence of chip diode is arranged on pin groove, metallic support also arranges groove 11, the body of chip diode also respectively correspondence be arranged in groove, the setting of pin groove and groove not only can position diode, unified position, and also reduce the whole height of photovoltaic module.
Busbar is introduced from the busbar introduction hole 5 at the bottom of box, and the busbar connecting hole 4 entered on metallic support is welded to connect.Cable puts into U-shaped intermediate plate 8, then is operated U-shaped intermediate plate clamping cables line by crimping hole 9.
The utility model is by changing the outlet method of cable, and in some occasions, cable can not carry out bending connection, decreases bending loss, can be positioned, facilitate installation by arranging of groove to diode.
