Abstract
The utility model discloses a prevent anti - photovoltaic terminal box of adorning, the on -line screen storage device comprises a base, be equipped with equal ascending anodal wiring hole of opening and negative pole wiring hole in this base, this positive pole wiring hole is the same with the bore depth in this negative pole wiring hole, and simultaneously, this base in -connection has the diode, this diode has anodal pin and negative pole pin, after buckling, this positive pole pin downward 90 is formed with anodal vertical section, the vertical section of negative pole that is formed with after this negative pole pin downward 90 is buckled, and, the vertical section of this positive pole is pegged graft downtheholely in this positive pole wiring, the vertical section of this negative pole is pegged graft downtheholely in this negative pole wiring, slow -witted post is prevented to downthehole being equipped with of negative pole wiring, and the length of the vertical section of this positive pole is greater than the length of the vertical section of this negative pole. The utility model has the advantages that: the qualification rate is higher.
Description
Technical field
This utility model relates to photovoltaic module technical field, especially relates to a kind of anti-reverse mounting photovoltaic junction box.
Background technology
At present, most diodes within photovoltaic junction box are circular shaft shape, and pin is to install after straight line or bending symmetric length.So, when assembling, anti-loaded phenomenon easily occurs, thus reduces the qualification rate of product to a certain extent, even can cause the destruction of solar photovoltaic assembly.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-reverse mounting photovoltaic junction box, and it has the advantages that qualification rate is higher.
This utility model the technical scheme is that anti-reverse mounting photovoltaic junction box, including base, opening positive terminal hole the most upwards and negative terminal hole it is provided with in this base, this positive terminal hole is identical with the hole depth in this negative terminal hole, simultaneously, connect in this base and have diode, this diode has positive pole pin and negative pole pin, it is formed with the vertical section of positive pole after the downward 90 ° of bendings of this positive pole pin, the vertical section of negative pole being formed after the downward 90 ° of bendings of this negative pole pin, and, the vertical section of this positive pole is plugged in this positive terminal hole, the vertical section of this negative pole is plugged in this negative terminal hole, it is provided with fool proof post in described negative terminal hole, and the length of the vertical section of this positive pole is more than the length of the vertical section of this negative pole.
This utility model is advantageously: qualification rate is higher.It is provided with fool proof post in the negative terminal hole of anti-reverse mounting photovoltaic junction box of the present utility model, and two pins of diode have the length vertical section of different positive poles and the vertical section of negative pole.The situation that diode is anti-loaded once occur, then fool proof post can head on the length vertical section of longer positive pole, makes diode cannot keep level, and a pin cannot insert in wiring hole even in.So, it is ensured that workman does not haves installation reversely in the case of operational error yet, thus not only the qualification rate of product is improved, and has more stopped because of the anti-loaded destruction causing solar photovoltaic assembly of diode.

Detailed description of the invention
Embodiment, as shown in Fig. 1 and Fig. 2: anti-reverse mounting photovoltaic junction box, including base 10, is provided with opening positive terminal hole 21 the most upwards and negative terminal hole 22 in this base 10, this positive terminal hole 21 is identical with the hole depth in this negative terminal hole 22.Meanwhile, connecting and have diode 30 in this base 10, this diode 30 has positive pole pin 31 and negative pole pin 32.It is formed with the vertical section of positive pole 311, the vertical section of negative pole 321 being formed with after the downward 90 ° of bendings of this negative pole pin 32 after the downward 90 ° of bendings of this positive pole pin 31.And, the vertical section of this positive pole 311 is plugged in this positive terminal hole 21, and the vertical section of this negative pole 321 is plugged in this negative terminal hole 22.Obviously, positive terminal hole 21 and negative terminal hole 22 are arranged in pairs, and the most only have a pair positive terminal hole 21 and negative terminal hole 22 in this base 10, and the most non-only one of corresponding diode 30.
Further say, be provided with fool proof post 40 in this negative terminal hole 22, and the length of the vertical section of this positive pole 311 is more than the length of the vertical section of this negative pole 321.Such as, the length of the vertical section of this positive pole 311 is equal to the hole depth in this positive terminal hole 21, and when installing correct, the vertical section of this positive pole 311 is plugged in this positive terminal hole 21 completely；Meanwhile, the length sum of the height of this fool proof post 40 and the vertical section of this negative pole 321 is equal to the hole depth in this positive terminal hole 21, thus the vertical section of negative pole 321 also can be plugged in this negative terminal hole 22 completely.Otherwise, when diode 30 is anti-loaded, under the effect of this fool proof post 40, the vertical section of this positive pole 311 cannot be in grafting enters this negative terminal hole 22 completely, and on the premise of keeping this diode 30 level, and the vertical section of this negative pole 321 cannot be introduced in this positive terminal hole 21.So, the situation of the anti-loaded diode of workman 30 has been stopped, it is ensured that stablizing of product quality.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
